The tool changing driving member 221 is connected with the first chain wheel 222 and/or the second chain wheel 223 to drive the first chain wheel 222 and the second chain wheel 223 to rotate.

The support plate 225 is used for carrying the tool holder 210 structure, and a plurality of support plates 225 are connected with the chain 224 to move under the driving of the chain 224. Specifically, a plurality of clamping jaws 2300 may be disposed on any supporting plate 225, and the plurality of clamping jaws 2300 are spaced apart along the length direction of the tool structure 300, so as to clamp the tool structure 300 more stably.

Of course, the tool changing drive assembly 220 can drive the plurality of support plates 225 to move periodically by other drive means besides chain drive, such as belt drive, multi-stage gear drive, etc.

Referring to fig. 2 and 3, in one embodiment, the tool holder 210 specifically includes a frame 211 and a mounting plate 212. Tool changing drive assembly 220 is mounted on mounting plate 212 and is coupled to tool post 210 via mounting plate 212.

So set up, can guarantee that bearing plate 225 is the stable position in the motion process along with chain 224.

In one embodiment, the jaws 2300 are capable of resiliently gripping the tool structure 300.

Referring to fig. 4-6, in one embodiment, the machine tool apparatus 100 includes a base assembly 110, a headstock 150, a support structure 120, and an alignment drive structure 130. The supporting frame structure 120 is slidably engaged with the base assembly 110, and the supporting frame structure 120 includes a plurality of clamping jaws 121, and the plurality of clamping jaws 121 are used for correspondingly clamping the plurality of connection kits 320. The alignment driving structure 130 is connected to the supporting frame structure 120 to drive the plurality of clamping jaws 121 to move along the first direction to positions corresponding to the plurality of connecting members 320. That is, the supporting frame structure 120 can slide in a first direction relative to the base assembly 110, so that the positions of the clamping jaws 121 and the connecting sleeves 320 correspond to each other. The first direction is referred to as a direction K in fig. 4, 5, and 6.

In the machine tool device 100, the gun drill 310 is provided with the plurality of connection kit parts 320 at intervals, and the plurality of clamping jaws 121 can clamp the plurality of connection kit parts 320 correspondingly. It will be appreciated that a plurality of connection sets 320 are axially spaced apart. That is, the plurality of coupling kits 320 are held by the plurality of holding claws 121, so that the gun drill 310 can be stably mounted on the base unit 110 and stably mounted on the machine tool device 100 while being axially fixed to the entire support frame structure 120.

The alignment driving structure 130 is connected to the supporting frame structure 120, and the alignment driving structure 130 can drive the plurality of clamping jaws 121 to move along the first direction to positions corresponding to the plurality of connecting kits 320. In other words, the alignment driving mechanism 130 can drive the plurality of jaws 121 to move in the first direction, so that the positions of the plurality of jaws 121 correspond to different positions of the plurality of connection kits 320. Further, the plurality of jaws 121 can be automatically adapted to grip the connection kit 320 of different types of gun drills 310 to automatically adapt to and grip different types of tool structures 300.

In one embodiment, the machine tool apparatus 10 further comprises a control system (not shown, the same applies below) coupled to each of the plurality of jaws 121 to control the opening and clamping of any of the jaws 121. The plurality of clamping jaws 121 may be embodied as pneumatic clamping jaws 121, i.e. the control system enables the plurality of clamping jaws 121 to automatically clamp or unclamp the tool structure 300 by pneumatic control.

Referring to fig. 5, in one embodiment, the headstock 150 can drive the gun drill 310 to move to drill a workpiece. Specifically, the spindle box 150 is provided with an insertion hole (not shown, the same applies below) for inserting and matching with the tool shank 311 of the gun drill 310. The headstock 150 can drive the gun drill 310 to integrally rotate through the tool shank 311, so as to realize the drilling movement of the gun drill 310. Specifically, the insertion hole is opened along a first direction, and the tool structure 300 can insert the tool shank 311 into the insertion hole along the first direction. Further, the headstock 150 is movable in the first direction. Thus, after the supporting frame structure 120 is connected to the tool structure 300, the spindle box 150 can move in the first direction to actively insert and mate the insertion hole with the tool shank 311. Of course, the tool holder 311 may be inserted into the receptacle by driving the tool assembly 300 to move in the first direction by the alignment driving mechanism 130.

Referring to fig. 7, in one embodiment, the base assembly 110 includes a column 111, a sliding platform 112, and a ram 113. The supporting frame structure 120 and the alignment driving structure 130 are disposed on the ram 113, the ram 113 is disposed on the sliding table 112, the sliding table 112 is disposed on the column 111, and the sliding table 112 can slide along the second direction relative to the column 111. A preset included angle is formed between the second direction and the first direction. The tool structure 300 can be moved to different stations by sliding the slide table 112 relative to the column 111. Of course, when tool changing is required, the sliding table 112 can slide relative to the column 111, so that the supporting frame structure 120 can move to the position corresponding to the tool magazine 200 in the second direction, and the clamping jaws 121 can clamp the tool structure 300 conveniently. Referring to arrow M in fig. 7, the first direction and the second direction may be perpendicular to each other, and of course, there may be other preset angles between the first direction and the second direction.

Referring again to fig. 1 and 2, in one embodiment, the tool magazine 200 is capable of moving in a third direction toward and away from the machine tool device 100 to provide or retract the tool structure 300 to the machine tool device 100. It will be appreciated that the magazine 200 stores a number of different types of tools. When the machine tool device 100 needs to replace different types of tools, after the tool magazine 200 is moved in a direction approaching the machine tool device 100 along the third direction to a position where the tool structure 300 can be clamped by the clamping jaws 121, the alignment driving structure 130 drives the clamping jaws 121 to move along the first direction to positions corresponding to the connecting suites 320 on the tool structure 300 to be clamped, so that the clamping jaws 121 can automatically adapt to and clamp different types of tool structures 300, and the tool structure 300 can be automatically loaded. In addition, in this embodiment, the tool magazine 200 can automatically move closer to and away from the machine tool device 100 in the third direction, so that automatic tool loading, automatic tool unloading, and automatic tool changing of the machine tool device 10 can be realized by cooperation of the tool magazine 200 and the machine tool device 100.

Referring to fig. 6, in one embodiment, the supporting frame structure 120 includes a first supporting frame 122 and a second supporting frame 123, which are slidably engaged with the base assembly 110. The first support frame 122 and the second support frame 123 are respectively provided with at least one clamping jaw 121. The alignment driving structure 130 is connected to both the first support frame 122 and the second support frame 123 to respectively drive the first support frame 122 and the second support frame 123 to move along the first direction. In other words, the alignment driving structure 130 drives the clamping jaws 121 on the first supporting frame 122 and the second supporting frame 123 to move along the first direction respectively. With this arrangement, the alignment driving structure 130 can be simplified as much as possible while ensuring that all the plurality of gripping claws 121 can move in the first direction.

It can be understood that, since the plurality of clamping jaws 121 all move along the first direction, at least one clamping jaw 121 is disposed on each of the first supporting frame 122 and the second supporting frame 123, and the movement of any clamping jaw 121 is not affected. When the first support frame 122 or the second support frame 123 includes two or more clamping jaws 121, the clamping capability can be improved.

Of course, the supporting frame structure 120 may also include a third supporting frame, a fourth supporting frame, etc. similar to the first supporting frame 122 and the second supporting frame 123 described above according to the number of the clamping jaws 121 or other requirements.

Referring to fig. 6, in one embodiment, the base assembly 110 is provided with a bracket rail 113a extending along a first direction. The alignment driving structure 130 includes a first driving rod 131 and a second driving rod 132. The first driving rod 131 is connected to the first support frame 122 to drive the first support frame 122 to move along a first direction, and the first driving rod 131 extends along the first direction. It is understood that the first driving rod 131 can be a lead screw, and the first supporting frame 122 is sleeved on the first driving rod 131 and is in threaded fit with the first driving rod 131, so that when the first driving rod 131 rotates, the first supporting frame 122 can be driven to move along an axis of the first driving rod 131, that is, the first supporting frame 122 is driven to move along the first direction.

Of course, in some embodiments, the alignment driving mechanism 130 may be other linear drivers, such as when the alignment driving mechanism 130 is an electric push rod, the first driving rod 131 is an output rod of the electric push rod. The first support frame 122 is connected to a first driving rod 131, and the first driving rod 131 can move along a first direction to push the first support frame 122 to move along the first direction.

Further, the first support frame 122 is in sliding fit with the support slide rail 113a, and the movement of the first support frame 122 along the first direction can be limited and guided by the support slide rail 113a, so that the first support frame 122 can accurately move along the first direction.

Referring to fig. 6, in one embodiment, the second driving rod 132 is connected to the second supporting frame 123 to drive the second supporting frame 123 to move along the first direction. The second drive rod 132 extends in a first direction and/or the second drive rod 132 moves in the first direction. The connection and driving manner of the second driving rod 132 and the second supporting frame 123 is similar to that of the first driving rod 131 and the first driving frame, and therefore, the connection and driving manner is not described again. It is understood that the second support frame 123 can also be slidably engaged with the rack rail 113a to ensure that the second support frame 123 accurately moves along the first direction. Of course, the second support frame 123 may be slidably engaged with other slide rails. That is, two sliding rails may be respectively disposed to be slidably engaged with the first support frame 122 and the second support frame 123.

For convenience of understanding, the first driving rod 131 and the second driving rod 132 are taken as lead screws in each embodiment for description, and therefore, the description of each embodiment is not repeated.

Referring to fig. 8 and 9 in conjunction with fig. 4 to 6, in one embodiment, an axis of the gun drill 310 when the cradle structure 120 and the gun drill 310 are clamped is defined as a reference axis, and the reference axis is parallel to the first direction. The base assembly 110 is provided with a guide sleeve seat 140, and the guide sleeve seat 140 is provided with a bearing sleeve hole 141 coaxial with the reference axis. The alignment driving structure 130 is used for driving a connection kit 320 to penetrate into the bearing sleeve hole 141 and to be clamped with the hole wall of the bearing sleeve hole 141. The connection sleeve 320 is sleeved on the gun drill 310, so that when the clamping jaws 121 clamp the connection sleeve 320, the connection sleeve 320 clamped by the clamping jaws 121 can slide along the reference axis relative to the gun drill 310 and penetrate into the bearing sleeve hole 141 under the driving of the alignment driving structure 130. So set up, through the joint cooperation of connecting external member 320 and bearing housing hole 141 pore wall, can further guarantee the stability of the relative base subassembly 110 position of gun drill 310.

The guide sleeve seat 140 may be specifically disposed at an end of the ram 113 far from the headstock 150, that is, the guide sleeve seat 140 is disposed at an end of the ram 113 near the worktable 400.

To facilitate understanding of the connection kit 320 and the guide sleeve seat 140, a specific embodiment is described below. In one embodiment, referring to fig. 5 and 6, the plurality of connection sets 320 of the cutter structure 300 includes at least one bearing sleeve 330 and at least one damping sleeve 340. The cutter structure 300 may specifically include 3 connecting members 320, including 2 damping sleeves 340 and 1 bearing sleeve 330. Correspondingly, the supporting frame structure 120 includes 3 clamping jaws 121, wherein 2 clamping jaws 121 are disposed on the first supporting frame 122. Referring to fig. 6, the first support frame 122 is closer to the guide sleeve seat 140 than the second support frame 123, the bearing sleeve 330 is one of the plurality of connection sleeves 320 closest to the guide sleeve seat 140, and the clamping jaw 121 for clamping the bearing sleeve 330 is one of the first support frame 122 relatively close to the guide sleeve seat 140.

Referring to fig. 10 to 12, when the tool magazine 200 transports the tool assembly 300 to a position where it can be held by the supporting frame assembly 120, as shown in fig. 10, the 2 clamping jaws 121 on the first supporting frame 122 can respectively hold the bearing sleeve 330 and one of the damping sleeves 340. As shown in fig. 12, the bearing sleeve 330 can be driven by the first support frame 122 to penetrate into the bearing sleeve hole 141 and be clamped with the hole wall of the bearing sleeve hole 141. Subsequently, the first support frame 122 can bring the damping sleeve 340 clamped by the first support frame to move axially to a desired position of the damping sleeve 340.

It will be appreciated that this arrangement enables the machine tool apparatus 100 to include 4 positions for axially supporting the gun drill 310 in the case where the support frame structure 120 includes only the first support frame 122 and the second support frame 123. The 4 positions refer to 2 clamping jaws 121, the guide sleeve holder 140 and the spindle box 150.

It should be noted that the damping sleeve 340 and the bearing sleeve 330 are not separated from the gun drill 310 when the tool structure 300 is in any normal state of working or storage. It can be understood that the gun drill 310 has a larger dimension in the axial direction than in the radial direction, i.e. the gun drill 310 tends to have an elongated shape, which is prone to radial run-out during the machining process, thereby affecting the machining accuracy. The gun drill 310 is connected to the machine tool device 100 through the shock-absorbing bush 340 and the bearing bush 330, so that radial run-out of the gun drill 310 during machining can be reduced.

Referring to fig. 5, the bearing housing 330 is disposed at an end of the gun drill 310 away from the tool shank 311, that is, the bearing housing 330 is disposed at an end of the gun drill 310 close to the cutting portion. It can be understood that the end of the gun drill 310 for cutting is a large shaking portion of the gun drill 310, so that the gun drill 310 can be more effectively supported by the guide sleeve seat 140 in cooperation with the bearing sleeve 330.

Referring to fig. 9 in combination with fig. 13, in an embodiment, a limiting member 142 is disposed on the guide sleeve base 140, and the limiting member 142 is used for being clamped with a connection sleeve 320 passing through the bearing sleeve hole 141 to fix the connection sleeve 320 relative to the guide sleeve base 140. That is, the stopper 142 is engaged with the connection sleeve 320, so that the connection sleeve 320 is stably located in the guide sleeve seat 140.

Specifically, the limiting member 142 is used to be engaged with the bearing housing 330. The outer side of the bearing sleeve 330 is provided with a limiting groove 321, and the limiting member 142 can extend into the limiting groove 321 to abut against the groove wall of the limiting groove 321, so that the bearing sleeve 330 is fixed relative to the guide sleeve seat 140.

Please continue to refer to fig. 9 in combination with fig. 13, in an embodiment, specifically, the guide sleeve seat 140 is further provided with a limiting driving element 143 and a sensing element 144 connected to the limiting driving element 143, the limiting driving element 143 is connected to the limiting element 142, the sensing element 144 is configured to be triggered when the connection sleeve 320 passes through the bearing sleeve hole 141, and the sensing element 144 can control the limiting driving element 143 to start when triggered, so as to drive the limiting element 142 to be clamped with the connection sleeve 320 or separated from the connection sleeve 320 through the limiting driving element 143.

Referring to fig. 9, in one embodiment, a first fixing portion 322 and a second fixing portion 323 are disposed on any one of the connection members 320. The first fixing portion 322 and the second fixing portion 323 are distributed along the axial direction of the connection sleeve. The tool magazine 200 is connected to the first fixing portion 322, and the clamping jaw 121 clamps the second fixing portion 323. By such arrangement, the tool magazine 200 and the supporting frame structure 120 can be conveniently connected with the tool structure 300, and any one of the tool magazine 200 and the supporting frame structure 120 is connected with the tool structure 300.

Referring to fig. 9 in conjunction with fig. 10 to 12, in an embodiment, the limiting groove 321 is the first fixing portion 322. The first supporting frame 122 can be clamped at the second fixing position 323 through the clamping jaw 121 to fix the bearing sleeve 330 relative to the first supporting frame 122, so that the first supporting frame 122 can drive the bearing sleeve 330 to move into the bearing sleeve hole 141, and at this time, the limiting member 142 can correspond to the second fixing position 323, so that the limiting member 142 can directly extend into the limiting groove 321 to abut against the groove wall of the limiting groove 321. It will be appreciated that the tool magazine 200 is now separated from the tool arrangement 300, i.e. the tool magazine 200 is not connected to the second fastening location 323 on the tool arrangement 300.

Referring to fig. 3 to 15, in one embodiment, the claw 2300 of the tool magazine 200 includes a first claw member 2310, a second claw member 2320, a holder 2330, and an adjustment member 2340. The first and second pawls 2310 and 2320 are pivotally connected, and the first and second pawls 2310 and 2320 form a simple lever. The pivot 2370 is a pivot at the pivot connection between the first claw 2310 and the second claw 2320, and the holder 2330 elastically abuts against the first claw 2310 and/or the second claw 2320 on the same side of the pivot 2370, so that the first claw 2310 and the second claw 2320 on the side of the cutter structure 300 close to the pivot 2370, so that the holder 2330 holds the cutter structure 300. It will be appreciated that the holder 2330 brings the first and second jaw members 2310 and 2320 closer to each other by way of resilient abutment, i.e., the jaw 2300 grips the workpiece by way of resilient abutment under the action of the holder 2330. In other words, the jaw 2300 can be elastically clamped to the tool structure 300 at all times by the holder 2330. That is, when an external force can resist the elastic clamping force of the jaw 2300, the tool structure 300 can be separated from the jaw 2300 by pulling the tool structure 300 by the external force.

With the tool magazine 200 configured as above, when the tool magazine 200 moves in the third direction to the clamping jaws 121 to clamp the tool structure 300, only one of the tool magazine 200 and the supporting frame structure 120 needs to move in a direction away from each other to separate the tool structure 300 from the tool magazine 200, thereby facilitating automatic tool loading of the machine tool apparatus 10.

Referring to fig. 10-12, the latch 2300 may be specifically configured to clamp the first securing location 322 on the connecting sleeve 320.

Referring to fig. 15 and 16, the adjusting member 2340 is coupled to the first and/or second claw members 2310 and 2320 on the same side of the fulcrum 2370, so that the first and second claw members 2310 and 2320 on the same side of the fulcrum 2370 are close to or away from each other. In other words, the adjusting member 2340 can be connected with at least one of the first claw member 2310 and the second claw member 2320 on the same side of the lever, so that the included angle between the first claw member 2310 and the second claw member 2320 can be controlled, and therefore the opening and the clamping of the clamping jaws 2300 can be controlled. So set up, can be convenient for deposit, put cutter structure 300. It will be appreciated that to ensure that the jaws 2300 are able to securely grip the tool structure 300, the gripping force provided by the holder 2330 to the jaws 2300 tends to be high, so that it is laborious and time consuming to overcome the grip of the jaws 2300 by only manual force when loading the tool structure 300 in bulk into the magazine 200. The adjusting piece 2340 controls the opening and the clamping of the clamping jaws 2300, so that the cutter structure 300 can be stored and stored conveniently.

It should be noted that, for the holding member 2330 and the adjusting member 2340, both drive one of the first claw member 2310 and the second claw member 2320 to move relative to the other, so the holding member 2330 and the adjusting member 2340 only need to be connected to at least one of the first claw member 2310 and the second claw member 2320 to achieve the above-mentioned driving effect.

With continued reference to fig. 3-15, in one embodiment, the latch 2300 includes a retention portion 2350. The first claw 2310 includes a first hook portion 2311 and a first manipulation portion 2312 located on the other side of the fulcrum 2370 opposite to the first hook portion 2311, that is, the first hook portion 2311 and the first manipulation portion 2312 are respectively located on two sides of the fulcrum 2370. The second claw member 2320 includes a second hooking portion 2321 and a second manipulating portion 2322 located on the other side of the fulcrum 2370 opposite to the second hooking portion 2321, that is, the second hooking portion 2321 and the second manipulating portion 2322 are located on two sides of the fulcrum 2370 respectively.

The first hook portion 2311 and the second hook portion 2321 are located on the same side of the fulcrum 2370 and are both used for contacting the cutter structure 300, and the limiting member 142 is disposed between the first hook portion 2311 and the second hook portion 2321 and can be abutted against the first hook portion 2311 and the second hook portion 2321 at the same time, so that the jaw 2300 has a minimum opening angle. With this arrangement, the first hook 2311 and the second hook 2321 are prevented from rotating to contact with each other by the holder 2330. Referring to fig. 15, that is, even after the cutter structure 300 is separated from the jaw 2300, the jaw 2300 can be opened at a certain angle, and the first hooking portion 2311 and the second hooking portion 2321 are spaced apart from each other. Accordingly, the tool structure 300 can be pushed into the jaw 2300 from the space between the first hooking portion 2311 and the second hooking portion 2321, so that the jaw 2300 can be restored to the clamping of the tool structure 300. That is, providing the jaws 2300 with a minimum opening angle facilitates returning the tool structure 300 to the magazine 200.

Specifically, the end of the first hook 2311 and the end of the second hook 2321 away from the fulcrum 2370 are provided with the introduction surface 2301, and the introduction surface 2301 is inclined with respect to the middle plane between the first hook 2311 and the second hook 2321. The introduction surface 2301 can facilitate the tool structure 300 to gradually expand the jaw 2300. The above-mentioned intermediate plane participates in 15 and is denoted by U in fig. 16.

It is understood that the minimum opening angle of the clamping jaw 2300 can be reasonably set according to the radial dimension of the tool structure 300 on the basis of ensuring that the clamping jaw 2300 can stably clamp the tool structure 300, and the minimum opening angle can be specifically set by a person skilled in the art according to actual requirements, so that the minimum opening angle is not particularly limited herein.

It should be noted that the retaining member 2330, the adjustment member 2340 and the stopper 2350 are used to control the degree of opening and closing of the jaws 2300. Since the first claw 2310 and the second claw 2320 are rotatably connected to form a simple lever structure integrally formed by the claw 2300, the holding member 2330, the adjusting member 2340 and the limiting portion 2350 are connected to the first claw 2310 and the second claw 2320 on the same side of the fulcrum 2370 respectively, so that the purpose of controlling the opening and closing degree of the claw 2300 can be achieved, and the specific positions of the three can be designed according to the requirements of spatial distribution in the claw 2300 or the overall spatial distribution of the tool magazine 200. For example, the stopper 2350 may be disposed between the first manipulation part 2312 and the second manipulation part 2322 to ensure that the jaw 2300 has a minimum opening angle.

In one embodiment, specifically, the holder 2330 is an elastic member, and the holder 2330 can be disposed between the first manipulation part 2312 and the second manipulation part 2322 and abut against the first manipulation part 2312 and the second manipulation part 2322 at the same time. Thus, the first hook 2311 and the second hook 2321 can be moved closer to each other or at least have a movement tendency of being moved closer to each other by a simple lever and principle. When the holder 2330 is disposed between the first manipulating portion 2312 and the second manipulating portion 2322, the limiting member 142 can be disposed between the first hooking portion 2311 and the second hooking portion 2321 to reasonably distribute an internal space of the hooks.

Referring to fig. 15 and 16, in other embodiments, the claw 2300 further includes a housing 2360, and the first claw member 2310 and the second claw member 2320 are disposed in the housing 2360. The holders 2330 are elastic members and are two in number, wherein two ends of one holder 2330 abut against the housing 2360 and the first hook 2311 respectively, and two ends of the other holder 2330 abut against the housing 2360 and the second hook 2321 respectively. So configured, the holder 2330 can be prevented from affecting the space on the jaw 2300 for clamping, and a space for placing the tool structure 300 in the jaw 2300 is ensured. It is understood that the first and second fingers 2310, 2320 may be secured to the support plate 225 by a housing 2360.

In one embodiment, the first and second claw members 2310 and 2320 and the housing 2360 are provided with a contact groove 2361, and the holder 2330 extends into the contact groove 2361, and the holder 2330 can be limited by the contact groove 2361.

Referring to fig. 15 and 16, in one embodiment, the adjusting member 2340 includes a handle body 2341, a pulling body 2342, a first connecting body 2343 and a second connecting body 2344. The first connecting body 2343 is coupled to the first claw member 2310, and the second connecting body 2344 is coupled to the second claw member 2320. The first linkage body 2343 and the second linkage body 2344 are located on the same side of the fulcrum 2370, and the pulling body 2342 is coupled to both the first linkage body 2343 and the second linkage body 2344 to drive the two bodies to move towards or away from each other. That is, the pulling body 2342 is connected between the first connecting body 2343 and the second connecting body 2344 to pull or push the first connecting body 2343 and the second connecting body 2344 to move relative to each other, so as to drive the first claw member 2310 and the second claw member 2320 to move relative to each other, and thus the clamping jaws 2300 are opened and closed. The handle body 2341 is connected to the traction body 2342, and the handle body 2341 can drive the traction body 2342 to move when rotating.

Specifically, the handle body 2341 includes a cam portion 2341a. The cam portion 2341a is rotatably coupled to the traction body 2342, the outer surface of the cam portion 2341a abuts against the first coupling body 2343, and the distance from the position where the cam portion 2341a is rotatably coupled to the traction body 2342 to each position on the outer surface is different. With this arrangement, the cam portion 2341a can drive the traction body 2342 and the first connecting body 2343 to move relative to each other when rotating, so as to drive the claw 2300 to open and close. It will be appreciated that the pull body 2342 is now inserted through the first linkage 2343 and slidably coupled to the first linkage 2343.

Further, the first connection body abuts the side of the first jaw 2310 away from the second jaw 2320, and the second connection body abuts the side of the second jaw 2320 away from the first jaw 2310. The pulling body 2342 is movably inserted through the first connecting body 2343, the first claw member 2310 and the second claw member 2320 in sequence, and is connected to the second connecting body 2344. Referring to fig. 15 and 16, for example, when the handle body 2341 rotates, a distance between a rotary joint of the handle body 2341 and the pulling body 2342 and the first abutting portion changes, that is, the pulling body 2342 slides relative to the first connecting body 2343, the first claw member 2310 and the second claw member 2320, and drives the second connecting body 2344 to move along with the pulling body 2342, so that the distance between the first connecting body 2343 and the second connecting body 2344 changes, and the opening and closing degree between the first claw member 2310 and the second claw member 2320 changes.

It can be appreciated that because the pull body 2342 is disposed through the first and second jaw members 2310 and 2320, the pull body 2342 is capable of guiding and limiting the rotational movement of the first and second jaw members 2310 and 2320 relative to one another.

In one embodiment, the traction body 2342 may be a flexible structure such as a traction rope, a traction wire, or the like.

Of course, the traction body 2342 may be a rigid structure such as a traction rod or a traction shaft. At this time, the first and second claw members 2310 and 2320 are formed with a through hole 2302, the diameter of the through hole 2302 is slightly larger than the radial dimension of the pulling body 2342, so as to prevent the through hole 2302 from abutting against the pulling body 2342 and being unable to rotate with each other.

In one embodiment, the adjusting element 2340 is connected to the first manipulating part 2312 and the second manipulating part 2322, that is, the pulling body 2342 penetrates through the first manipulating part 2312 and the second manipulating part 2322. The first connecting body 2343 abuts against one side of the first manipulating part 2312, which is far away from the second manipulating part 2322, and the second connecting body 2344 abuts against one side of the second manipulating part 2322, which is far away from the first manipulating part 2312.

Correspondingly, the holder 2330 abuts against the first hook 2311 and the second hook 2321.

In one embodiment, any one of the plurality of support plates 225 can be moved to a pre-installation station by the tool change drive 221. That is, the tool changing driving member 221 drives the first chain wheel 222 and the second chain wheel 223 to rotate, so as to drive any supporting plate 225 to move to the pre-installation station by the chain 224. It will be appreciated that the pre-mounting station for the support plate 225 described above refers to the rotation of the support plate 225 to a position at which the tool structure 300 carried by the support plate 225 can be gripped by the jaws 121 of the machine tool arrangement 100. The carrier plate 225 indicated by the arrow C in figure 2 is at the pre-installation station.

Referring to fig. 2, 10 and 17, in one embodiment, the tool magazine 200 further includes a locking member 212a and a positioning member 225a. The locking member 212a is disposed on the tool holder 210, the number of the positioning members 225a is plural, and the plurality of positioning members 225a are disposed on the plurality of support plates 225 in a one-to-one correspondence. The tool changing drive 221 is coupled to each of the plurality of support plates 225 to drive any one of the support plates 225 to a pre-installation station, and the lock 212a is coupled to a positioning member 225a located on the support plate 225 at the pre-installation station to secure the support plate 225 relative to the tool post 210. That is, by fitting the positioning member 225a, any one of the support plates 225 can be accurately and stably positioned at the pre-installation station. Thus, the machine tool device 100 is convenient to cooperate with the tool magazine 200 to clamp the tool structure 300 on the tool magazine 200. Specifically, any one of the support plates 225 is accurately and stably located at the pre-installation station, so that a positioning error between the machine tool device 100 and the tool magazine 200 can be avoided, and the plurality of clamping jaws 121 can be guaranteed to accurately clamp the corresponding connection kit 320.

Referring to fig. 17, in one embodiment, the positioning element 225a and the locking element 212a can be positioned by a plug-in fit. Specifically, one of the locking member 212a and the positioning member 225a is provided with an insertion hole 225b, and the other is provided with a movable positioning pin 212b. With any of the support plates 225 in the pre-installation position, the positioning pins 212b can be inserted into the receptacles 225 b. Further, the positioning pin 212b may be driven to be inserted into the insertion hole 225b by an air cylinder, a hydraulic cylinder, or an electric push rod, or may be separated from the insertion hole 225 b.

The locking member 212a may be specifically provided on the mounting plate 212 to facilitate a locating engagement with the locating member 225a located on the support plate 225.

It should be noted that each movable, variable-state structure, etc. of the machine tool apparatus 10 may be controlled by a control system. For example, the sliding table 112 can be controlled by the control system to move in the second direction relative to the column 111, the tool magazine driving device 500 can be controlled by the control system to drive the tool magazine 200 to move in the third direction, and the positioning pin can be controlled by the control system to be inserted into or separated from the jack.

An embodiment of the application also provides an automatic tool changing method. The automatic tool changing method comprises a tool loading method and a tool unloading method.

The cutter installing method comprises the following steps:

and S11, adjusting the positions of the gun drill 310 to be installed and the plurality of connecting external members 320 in the tool magazine 200 to be in a pre-installation station. That is, the chain 224 is driven by the tool changing driving member 221 to move the carrying plate carrying the tool structure 300 to be mounted to the pre-mounting position.

And S12, controlling the plurality of clamping jaws 121 to move along the first direction respectively, so that the plurality of clamping jaws 121 correspond to the plurality of connecting kits 320 on the pre-installation station respectively. Specifically, the alignment driving structure 130 may drive the plurality of clamping jaws 121 to move to positions corresponding to the plurality of connection kits 320 along the first direction, so that the plurality of clamping jaws 121 can clamp the plurality of connection kits 320 correspondingly.

S13, the tool magazine 200 is driven to move in a direction to approach the base unit 110, and the plurality of clamping jaws 121 clamp the plurality of connection kits 320 correspondingly. Specifically, the plurality of clamping jaws 121 clamp the second fixing location 323 on the connection kit 320.

S14, the headstock 150 and/or the gun drill 310 are driven to move in the first direction, so that the shank 311 of the gun drill 310 is inserted into the headstock 150. In this way, the tool shank 311 and the main spindle box 150 are in driving connection, so that the main spindle box 150 drives the gun drill 310 to integrally rotate through the tool shank 311.

And S15, driving the tool magazine 200 to move in the direction away from the base assembly 110. Specifically, the tool magazine 200 may be driven by the tool magazine 200 to move in a third direction away from the base assembly 110. It will be appreciated that since the jaws 2300 resiliently grip the tool structure 300, the tool structure 300 can be disengaged from the jaws 2300 when the jaws 121 grip the coupling assembly 320 and the tool magazine 200 is moved in a direction away from the base assembly 110.

It should be understood that steps S11 and S12 do not have strict sequence difference, and S11 and S12 can also be performed simultaneously.

In one embodiment, step S11 further includes: the control positioning pin shaft is inserted into the jack, so that the locking piece 212a is inserted into the positioning piece 225a for positioning. So that the support plate 225 can be accurately and stably positioned at the pre-installation station.

In one embodiment, the knife loading method further comprises the following steps:

s16, one of the clamping jaws 121 and the corresponding connection kit 320 are driven to move along the first direction toward the direction close to the guide sleeve seat 140, and move to the connection kit 320 to penetrate through the guide sleeve seat 140. Specifically, the connection sleeve 320 penetrating the guide sleeve seat 140 may be a bearing sleeve 330, and the clamping jaw 121 clamping the connection sleeve 320 is one clamping jaw 121 on the first support frame 122 close to the guide sleeve seat 140.

S17, the guide sleeve base 140 is clamped with the connecting sleeve 320, so that the connecting sleeve 320 is fixed relative to the guide sleeve base 140. Specifically, the clamping jaw 121 drives the bearing sleeve 330 to move towards the guide sleeve seat 140, and when the bearing sleeve 330 moves to the position, the bearing sleeve 330 can trigger the sensing element 144, so that the sensing element 144 drives the limiting element 142 to be clamped with the connection kit 320 through the limiting driving element 143, and the bearing sleeve 330 is fixed relative to the guide sleeve seat 140.

S18, the driving jaw 121 retracts to the initial position along the first direction.

In one embodiment, the method for unloading the cutter comprises the following steps:

and S21, driving one clamping jaw 121 to move towards the direction close to the guide sleeve seat 140 along the first direction until the clamping jaw 121 can clamp the connecting sleeve 320 penetrating through the guide sleeve. I.e. the jaws 121 are able to grip the bearing housing 330.

S22, the guide sleeve seats 140 release the connection sleeve 320, the clamping jaws 121 clamp the connection sleeve 320, and the plurality of clamping jaws 121 are driven to move along the first direction to the position, corresponding to the position of the plurality of clamping jaws 2300 on the tool magazine 200, of the plurality of connection sleeve 320.

And S23, driving the main spindle box 150 and/or the gun drill 310 to separate the main spindle box 150 from the gun drill 310.

S24, the magazine 200 is driven to move in a direction approaching the base unit 110, the plurality of claws 2300 grip the plurality of connection kits 320, and the plurality of jaws 121 release the plurality of connection kits 320.

And S25, driving the tool magazine 200 to move in a direction away from the base assembly 110.

In one embodiment, in step S22, the control system may specifically directly control the limiting driving element 143, and the limiting element 142 is driven by the limiting driving element 143 to separate from the limiting groove 321, so that the guide sleeve seat 140 releases the connection sleeve 320. Alternatively, the sensing member 144 may sense that the clamping jaws 121 clamp the connection kit 320, thereby allowing the guide sleeve holder 140 to release the connection kit 320.

In one embodiment, step S24 further comprises:
