Compared with the prior art, the beneficial effect of this application lies in:

(1) The supporting seat on the left side can horizontally rotate on the rack on the left side, so that when one end of the supporting seat on the left side rotates to the upward loading station, a flange to be processed is clamped on a corresponding clamping mechanism, and the loading operation can be completed; in a similar way, the flanges needing to be processed can be clamped on the two clamping mechanisms on the left side, so that the production and processing efficiency is improved.

(2) The connecting line between the turning mechanism and the drilling mechanism penetrates through the rotating axis of the left supporting seat, so that after the feeding operation is completed, the left supporting seat is controlled to rotate clockwise until two ends of the supporting seat respectively face the drilling mechanism and the turning mechanism, the drilling mechanism is used for drilling one corresponding flange, so that a bolt hole is formed, correspondingly, the turning mechanism is just used for performing first turning on the other corresponding flange, namely turning on one end face, one half of outer ring face and one inner ring face of the flange; simultaneously, because the left supporting seat is clockwise rotation, consequently, the flange is earlier through drilling processing, carries out lathe work again, can carry out the chamfer to the one end of bolt hole simultaneously during lathe work promptly. That is, the drilling work and the first turning work are performed simultaneously, further improving the efficiency of the production work.

(3) After the flanges clamped on the clamping mechanism on the left side are sequentially drilled and turned for the first time, the supporting seat on the left side is continuously controlled to rotate clockwise, the supporting seat on the right side simultaneously rotates clockwise, when the clamping mechanism at one end of the supporting seat on the right side is aligned with the clamping mechanism on the left side, the clamping mechanism on the right side slides leftwards until the flanges on the clamping mechanism on the left side are clamped, the clamping mechanism on the left side loosens the flanges, at the moment, the flanges on the clamping mechanism on the left side are transferred to the clamping mechanism on the right side, an unprocessed end face of the flange just faces the outer side corresponding to the clamping mechanism, and the clamping mechanism on the right side slides rightwards after clamping the flanges, so that the flanges are completely separated from the clamping mechanism on the left side; in a similar way, the flanges after drilling and first turning can be clamped on the two clamping mechanisms on the right side. After the flange clamped on the clamping mechanism on the left side is transferred, the flange can continuously return to a loading station for clamping again. That is to say, the flange can automatically shift and adjust the direction of the flange after the first turning process, and the flange does not need to be clamped and positioned again manually.

(4) Because the connecting line between the turning mechanism and the milling mechanism penetrates through the rotating axis of the right supporting seat, after the flange is transferred to the right clamping mechanism, the right supporting seat is controlled to rotate clockwise until the two ends of the right supporting seat respectively face the turning mechanism and the milling mechanism, and the turning mechanism can perform secondary turning on one corresponding flange, namely, turning on one end surface, the other half of the outer ring surface and the other end chamfer of the bolt hole which are not machined by the flange; meanwhile, the milling mechanism can mill the other corresponding flange, so that the internal spline is formed. That is, the second turning and milling are carried out simultaneously, and the production and processing efficiency is further improved; moreover, since the right support seat also rotates clockwise, before the milling process, the turning process and the chamfering process can be performed on the inner annular surface of the flange through the first turning process (or the second turning process), so that a necessary processing basis is provided for milling the internal spline.

(5) After the flange is milled, the supporting seat on the right side is continuously controlled to rotate clockwise until the corresponding clamping mechanism faces the blanking station, and then the flange can be taken down to complete blanking operation; after the flange is taken down, the corresponding clamping mechanism can continue to rotate clockwise along with the supporting seat on the right side, so that the flange is clamped on the clamping mechanism on the left side again.

(6) According to the above, when the feeding station and the blanking station are arranged in the same operation area, namely, the feeding station and the blanking station are both positioned between the drilling mechanism and the milling mechanism and are positioned right in front of the turning mechanism; when the loading operation is carried out, one end of the supporting seat on the left side faces to the operation area so as to carry out one loading operation, and two ends of the supporting seat on the right side just face to the turning mechanism and the milling mechanism so as to carry out second turning on one flange and mill one flange while loading; when the blanking operation is carried out, one end of the supporting seat on the right side faces to an operation area so as to carry out the blanking operation once, and the two ends of the supporting seat on the left side just face to the drilling mechanism and the turning mechanism so as to carry out the drilling processing on one flange and carry out the turning processing on one flange for the first time while blanking. That is, the production efficiency can be greatly improved by the processing mode; in addition, the feeding station and the blanking station can be positioned in the same operation area, and the feeding operation and the blanking operation are staggered, so that all operations can be completed by only one operator, and the requirement on labor force is reduced; in the whole machining process, for the same flange, an operator only needs to complete one-time clamping positioning and one-time taking-out operation, so that the manual workload is small, and the working efficiency is higher. In addition, the turning mechanism can be horizontally and rotatably arranged behind the two supporting seats, so that when the feeding operation is carried out, the turning mechanism rotates anticlockwise to the clamping mechanism on the supporting seat facing to the right side, and the corresponding flange is turned for the second time; when the blanking operation is carried out, the turning mechanism rotates clockwise to the clamping mechanism on the supporting seat facing the left side, so that the corresponding flange is turned for the first time; that is to say, this digit control machine tool only need be equipped with one the turning mechanism, and equipment cost is lower.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1 to 5, an embodiment of the present application provides a numerical control machine tool for flange 300 machining, including a drilling mechanism 1, a turning mechanism 2, a milling mechanism 3, two frames 4, two supporting seats 5, and four clamping mechanisms 6 for clamping a flange 300; the two racks 4 are arranged at left and right intervals, and the two supporting seats 5 are respectively arranged on the two racks 4 in a horizontally rotatable manner; the two clamping mechanisms 6 are respectively arranged at two ends of the supporting seat 5 on the left side, and the distances between the two clamping mechanisms 6 and the rotating axis of the supporting seat 5 are equal; the other two clamping mechanisms 6 can be horizontally arranged at two ends of the right supporting seat 5 in a sliding manner, and the sliding directions of the two clamping mechanisms 6 are parallel to each other; the drilling mechanism 1 is arranged at the left front of the left supporting seat 5, and the milling mechanism 3 is arranged at the right front of the right supporting seat 5; the turning mechanism 2 is horizontally and rotatably arranged behind the two supporting seats 5, a connecting line between the turning mechanism 2 and the drilling mechanism 1 penetrates through the rotating axis of the supporting seat 5 on the left side, and a connecting line between the turning mechanism 2 and the milling mechanism 3 penetrates through the rotating axis of the supporting seat 5 on the right side.

As shown in fig. 2, since the left support seat 5 can horizontally rotate on the left frame 4, when one end of the left support seat 5 rotates to the upward loading station, the flange 300 to be processed is clamped on a corresponding clamping mechanism 6, and the loading operation can be completed; in a similar way, the flanges 300 to be processed can be clamped on the two clamping mechanisms 6 on the left side, so that the production and processing efficiency is improved.

As shown in fig. 3, since a connection line between the turning mechanism 2 and the drilling mechanism 1 passes through a rotation axis of the left support seat 5, after the feeding operation is completed, the left support seat 5 is controlled to rotate clockwise, and when two ends of the support seat 5 face the drilling mechanism 1 and the turning mechanism 2 respectively, the drilling mechanism 1 is used for drilling a corresponding flange 300, so as to form a bolt hole 301 (as shown in fig. 19); correspondingly, the turning mechanism 2 is just used for turning the other corresponding flange 300 for the first time, namely, turning one end face, a half outer ring face and an inner ring face of the flange 300; furthermore, since the left support seat 5 is rotated clockwise, one end of the bolt hole 301 can be chamfered at the same time when the flange 300 is first subjected to the drilling process and then subjected to the first turning process. That is, the drilling work and the first turning work are performed simultaneously, further improving the efficiency of the production work.

As shown in fig. 4, after the flange 300 clamped on the left clamping mechanism 6 is sequentially drilled and turned for the first time, the left supporting seat 5 is continuously controlled to rotate clockwise, and meanwhile, the right supporting seat 5 rotates clockwise until one clamping mechanism 6 at one end of the right supporting seat 5 is aligned with one clamping mechanism 6 at the left side, the right clamping mechanism 6 slides leftwards until the flange 300 on the left clamping mechanism 6 is clamped, the left clamping mechanism 6 releases the flange 300, at this time, the flange 300 on the left clamping mechanism 6 is transferred to the right clamping mechanism 6, an unprocessed end face of the flange 300 just faces the outer side of the corresponding clamping mechanism 6, and the right clamping mechanism 6 slides rightwards after clamping the flange 300, so that the flange 300 is completely separated from the left clamping mechanism 6; similarly, the flange 300 after drilling and first turning can be clamped on the two clamping mechanisms 6 on the right side. After the flange 300 clamped on the left clamping mechanism 6 is transferred, the flange can continuously return to the loading station for clamping again. That is to say, after the flange 300 is subjected to the first turning process, the direction of the flange 300 can be automatically transferred and adjusted, and the flange 300 does not need to be manually clamped and positioned again.

As shown in fig. 3, since a connection line between the turning mechanism 2 and the milling mechanism 3 passes through a rotation axis of the right-side support seat 5, after the flange 300 is transferred to the right-side clamping mechanism 6, the right-side support seat 5 is controlled to rotate clockwise until two ends of the right-side support seat 5 respectively face the turning mechanism 2 and the milling mechanism 3, the turning mechanism 2 performs a second turning process on a corresponding flange 300, that is, a non-processed end surface of the flange 300, the other half of the outer ring surface, and a chamfer of the other end of the bolt hole 301 are subjected to turning process; at the same time, the milling mechanism 3 mills the respective other flange 300 to form the internal spline 302 (as shown in fig. 20). That is, the second turning and milling are simultaneously carried out, and the production and processing efficiency is further improved; moreover, since the right-side support seat 5 also rotates clockwise, the inner annular surface of the flange 300 can be turned and chamfered by the first turning (or the second turning) before the milling process, thereby providing a necessary processing basis for milling the internal spline 302. After the flange 300 is milled, the right supporting seat 5 continues to be controlled to rotate clockwise until the corresponding clamping mechanism 6 faces the blanking station, and then the flange 300 can be taken down to complete blanking operation; after the flange 300 is taken down, the corresponding clamping mechanism 6 can continue to rotate clockwise along with the supporting seat 5 on the right side, so that the flange 300 is clamped on the clamping mechanism 6 on the left side again.

As shown in fig. 2 to 4, the feeding station and the discharging station are disposed in the same operation area 200, that is, the feeding station and the discharging station are both located between the drilling mechanism 1 and the milling mechanism 3 and directly in front of the turning mechanism 2. As shown in fig. 2, when the loading operation is performed, one end of the left support seat 5 faces the operation area 200 so as to perform one loading operation, and both ends of the right support seat 5 just face the turning mechanism 2 and the milling mechanism 3 so as to perform a second turning process on one flange 300 and perform a milling process on one flange 300 while the loading operation is performed. As shown in fig. 3, when the blanking operation is performed, one end of the support seat 5 on the right side faces the operation area 200 so as to perform the blanking operation, and both ends of the support seat 5 on the left side just face the drilling mechanism 1 and the turning mechanism 2 so as to drill one flange 300 and perform the first turning on one flange 300 while blanking. That is, the production efficiency can be greatly improved by the processing mode; in addition, the feeding station and the blanking station can be positioned in the same operation area 200, and the feeding operation and the blanking operation are staggered, so that all operations can be completed by only one operator, and the requirement on labor force is reduced; moreover, in the whole machining process, for the same flange 300, an operator only needs to complete one-time clamping and positioning and one-time taking-out operation, the manual workload is small, and the working efficiency is higher. In addition, since the turning mechanism 2 is horizontally and rotatably arranged behind the two supporting seats 5, when the feeding operation is performed, the turning mechanism 2 rotates counterclockwise to the clamping mechanism 6 on the supporting seat 5 facing the right side, so that the corresponding flange 300 is turned for the second time; during blanking operation, the turning mechanism 2 rotates clockwise to the clamping mechanism 6 on the support seat 5 facing the left side, so that the corresponding flange 300 is turned for the first time; that is to say, the numerical control machine tool only needs to be equipped with one turning mechanism 2, and the equipment cost is lower.

It should be noted that the drilling mechanism 1, the turning mechanism 2, and the milling mechanism 3 are all prior art, and detailed description thereof is omitted in this application. In addition, the present application does not limit the horizontal rotation mounting manner of the turning mechanism 2, for example, the entire turning mechanism 2 is mounted on a rotating platform, and the horizontal rotation of the turning mechanism 2 can be realized by controlling the horizontal rotation of the rotating platform, so that the turning mechanism 2 can alternately perform the first turning process and the second turning process. In addition, the present application does not limit the horizontal rotation installation manner of the support base 5, for example, a vertical shaft 52 is installed at the lower side of the support base 5, the vertical shaft 52 is rotatably installed inside the frame 4 through a bearing and a bearing seat, and meanwhile, a servo motor is installed inside the frame 4, and an output shaft of the motor is connected with the vertical shaft 52 through a transmission mechanism, so that the vertical shaft 52 (i.e., the support base 5) can be driven by the servo motor to horizontally rotate by a designated angle, so as to complete the corresponding operation.

Referring to fig. 5, 6, and 8, in the present embodiment, each of the four chucking mechanisms 6 includes a case 61, a rotary shaft 62, a driving member, and a chucking member 63; the two box bodies 61 are respectively arranged at two ends of the left support, and the distances between the two box bodies 61 and the rotating axis of the support seat 5 are equal; the other two boxes 61 are respectively arranged on the right supporting seat 5 in a horizontally sliding manner, and the sliding directions of the two boxes 61 are parallel to each other; the four rotating shafts 62 are respectively rotatably arranged on the four box bodies 61, and the two rotating shafts 62 positioned on the same box body 61 are coaxially arranged along the horizontal direction; the four driving members are respectively arranged inside the four box bodies 61, and the four driving members are respectively used for driving the four rotating shafts 62 to rotate; four clamping pieces 63 are coaxially provided at outer ends of the four rotating shafts 62, respectively, and the four clamping pieces 63 are used to automatically clamp or unclamp the flange 300, respectively. Wherein, the clamping location to flange 300 can be realized to the clamp through clamping piece 63's clamp, and when taking place to rotate through driving piece drive rotation axis 62, rotation axis 62 can drive corresponding clamping piece 63 and realize rotating. When the clamping member 63 rotates, the flange 300 clamped on the clamping member 63 also rotates. When the drilling mechanism 1 adopts a single drill, after each bolt hole 301 is drilled, the clamping member 63 clamps the flange 300 to rotate by 60 degrees (60 degrees is an included angle between two adjacent bolt holes 301, the flange 300 is provided with six bolt holes 301, namely, the included angle between two adjacent bolt holes 301 is 60 degrees), so that the next bolt hole 301 is drilled continuously, and the like until the six bolt holes 301 are drilled. When the turning mechanism 2 is a lathe, the driving member drives the rotating shaft 62 to rotate at a high speed during the first turning and the second turning, and the rotating shaft 62 can drive the clamping member 63 (i.e., the flange 300) to rotate at a high speed, so as to achieve the turning. In the present invention, the rotatable mounting manner of the rotating shaft 62 is not limited, and for example, the rotating shaft 62 is rotatably mounted on the housing 61 through a bearing. In addition, the driving member itself is a conventional one, for example, the driving member is a motor, and an output shaft of the motor is connected to the rotating shaft 62 through a transmission mechanism, so that the rotating shaft 62 can be driven to rotate by the motor. In the present invention, the slide-mounting manner of the two cases 61 on the right-hand support base 5 is not limited, and for example, a guide rail is provided on the support base 5, a guide groove at the lower end of the case 61 is slidably connected to the guide rail, and the case 61 is driven to slide horizontally by a lead screw drive mechanism.

As shown in fig. 9 and 10, the open end of the case 631 is coaxially connected to the rotary shaft 62 through the cover 632; at least three sliding grooves 6311 are radially arranged on the end surface of the casing 631, which is far away from the rotating shaft 62, the included angle between two adjacent sliding grooves 6311 is equal, and the inner wall of each sliding groove 6311 is provided with a limit groove 6312 (as shown in fig. 10 and 13) for communicating the inside of the casing 631; as shown in fig. 9 to 11, the number of the sliding blocks 633 is at least three, each sliding block 633 is slidably connected to each sliding groove 6311, and a seal is formed between each sliding block 633 and the corresponding limiting groove 6312 (as shown in fig. 13, the limiting groove 6312 is sealed by the sliding block 633, so as to prevent chips and cooling liquid generated in the machining process from entering the inside of the housing 631 through the limiting groove 6312); as shown in fig. 11 to 13, a clamping block 6331 is disposed on a side surface of each slider 633 away from the cover 632, and a clamping block 6332 is disposed on a side surface of each slider 633 close to the cover 632; each clamping block 6332 is slidably connected to each limiting groove 6312, and a tapered surface 6333 is arranged at one end of each clamping block 6332 close to the cover body 632; the number of the first springs 635 is at least three, each first spring 635 is arranged inside the housing 631, and each first spring 635 is used for driving each fixture block 6332 to slide radially outwards; piston ring 634 is axially slidably disposed inside casing 631, a tapered ring surface 6341 is disposed between an end surface of piston ring 634 away from cover 632 and an inner ring surface, and a closed cavity 638 is defined between piston ring 634, casing 631, and cover 632; the second spring 636 is disposed inside the casing 631, and the second spring 636 is used for driving the piston ring 634 to slide in a direction close to the cover 632. The inside of the rotating shaft 62 is coaxially provided with a passage 621 (as shown in fig. 12) for communicating with the chamber 638, a rotating port of the third rotating joint 637 is coaxially communicated with an end of the passage 621 far from the chamber 638, and a fixed end of the third rotating joint 637 is fixed to the corresponding case 61 (as shown in fig. 6 or fig. 8). As shown in fig. 12 and 13, when the chamber 638 is filled with liquid or gas through the third rotary joint 637 until the piston ring 634 is driven to slide away from the cover 632, the tapered ring surface 6341 forces the respective locking blocks 6332 to slide radially inward through the respective tapered surfaces 6333, thereby automatically clamping the flange 300 between the respective locking blocks 6331. When the liquid or gas in the cavity 638 is exhausted, the piston ring 634 slides to a direction close to the cover 632 under the action of the second spring 636, so as to automatically realize the reset; at this time, each latch 6332 is also slid radially outward by the first spring 635, so that the flange 300 clamped between the latches 6332 is automatically released. The rotation port and the fixed end of the third rotation joint 637 can rotate relative to each other, so that liquid (or gas) can be introduced into or removed from the channel 621 when the fixed end of the third rotation joint 637 is not fixed and the rotation shaft 62 rotates.

When the first manifold 72 is externally connected with positive pressure (i.e. liquid or gas is supplied into the first manifold 72), the corresponding first control valve 74 is opened, so that liquid or gas can be supplied into the corresponding third rotary joint 637, thereby clamping the flange 300; when the first manifold 72 is connected externally with a negative pressure, the corresponding first control valve 74 is opened, and the liquid or gas in the corresponding third rotary joint 637 can be discharged, so that the clamping effect on the flange 300 is released. In addition, the rotation port and the fixed end of the first rotary joint 71 can allow relative rotation, so that when the support base 5 rotates, the fixed end of the first rotary joint 71 can rotate relative to the rotation port (i.e., the first manifold 72) of the first rotary joint 71 in an adaptive manner, thereby avoiding interference. In addition, since relative sliding between the box 61 on both sides of the first rotary joint 71 and the supporting seat 5 below does not occur, the first branch pipe 73 can adopt a rigid structure, so that the fixed end of the first rotary joint 71 is not fixed by the bracket 51; of course, the first branch pipe 73 may also be of a flexible structure, and the fixed end of the first rotary joint 71 needs to be fixed by the bracket 51.
