As shown in fig. 1 to 5, the present invention provides a metal cutting machine tool capable of rapid clamping, comprising:
The disc workbench 1 is provided with a plurality of guide grooves 2 uniformly distributed in the radial direction of the disc workbench 1, and the guide grooves 2 extend from the circumferential edge of the disc workbench 1 to the circle center of the disc workbench 1;
the surface of the disc workbench 1 is provided with a concentric ring group 3, each ring of the concentric ring group 3 is uniformly divided into a plurality of arc-shaped shells 4 by a plurality of guide grooves 2, and the arc-shaped shells 4 are arranged on the disc workbench 1 through a spring assembly 5;
The clamping body 6, the clamping body 6 includes a driving component 7 installed inside the disc workbench 1 and a claw body 8 arranged in the guide groove 2, the claw body 8 protrudes out of the plane of the disc workbench 1, and the driving component 7 is used for synchronously driving the plurality of claw bodies 8 to move along the guide groove 2 until contacting with the surface of a metal piece to be processed placed on the disc workbench 1.
The invention provides a technical scheme capable of realizing automatic clamping of a metal piece to be cut on a workbench, which mainly comprises the step of enabling an arc-shaped shell 4 to be provided with position adjustment in the longitudinal direction (the axial direction of the whole disc workbench) through a spring assembly 5, namely, when the metal piece is placed on the disc workbench 1, the metal piece to be cut has certain adaptability to the irregular metal piece to be cut (the surface of the metal piece to be cut, which contacts the disc workbench 1), meanwhile, the height of the arc-shaped shell 4 pressed by the metal piece to be cut is reduced, so that the height difference exists between two adjacent arc-shaped shells 4 in the radial direction of the disc workbench 1, and the metal piece to be cut can be pre-clamped through the generated height difference.
At this time, the driving assembly 7 works, the driving assembly 7 drives the plurality of claw bodies 8 to move along the guide groove 2 until the claw bodies are contacted with the surface of the metal piece to be cut, wherein the positions of the claw bodies 8 for the metal piece to be cut are stressed and changed, and the corresponding supporting points are found between the metal piece with the cut and the arc-shaped shell 4 again, that is, more supporting positions exist between the claw bodies 8 and the arc-shaped shell 4, so that stable clamping is completed.
That is, the clamping of the machine tool provided by the invention is based on the pre-clamping of the metal piece to be cut and the common clamping of the claw bodies 8 driven by the driving device, so that the rapid clamping process of the metal piece to be cut is realized, the manual clamping operation of the manual clamping on each claw body 8 is avoided, and the position adjustment of the metal piece to be cut in the clamping process is avoided.
Of course, in view of the actual clamping situation, the surface of the jaw 8 contacting the metal piece may be provided with a rubber pad to avoid direct contact with the surface of the metal piece to be cut.
Further, in order to realize rapid clamping of the claw body 8, the disc workbench 1 comprises an upper workbench body 101, a middle workbench body 102 and a lower workbench body 103, which are mainly in disc-shaped structures, a plurality of guide grooves 2 are arranged on the surface of the upper workbench body 101, the guide grooves 2 extend to the center of the middle workbench body 102 along the axial direction of the upper workbench body 101, and a driving assembly 7 is arranged on the middle workbench body 102; the upper bench body 101 is fixedly connected with the lower bench body 103 through the fixing rod 104, the fixing rod 104 penetrates through the middle bench body 102, and the center through hole 105 for the fixing rod 104 to penetrate is formed in the middle bench body 102, so that when the metal piece to be cut is clamped, a large force is needed to be provided, the claw body 8 is directly driven by the driving device to clamp the metal piece, the stress of the metal piece in the cutting process directly acts on the driving part of the clamping assembly, the driving part is easy to damage in the long-time working process, the claw body 8 is arranged on the middle bench body 102, the middle bench body 102 is provided with a certain mass, and the acting force acting on the claw body 8 firstly needs to overcome the moment of inertia of the middle bench body 102 around the fixing rod 104, and then is transmitted to the driving assembly 7 through the acting force.
Further, in order to improve the stability of clamping, the method of increasing the friction force is mainly adopted, so on the basis of the above, the upper surface and the lower surface of the middle platform body 102, which are close to the outer ring, are provided with annular grooves 106, and the upper platform body 101 and the lower platform body 103 are provided with friction ring bodies 107 matched with the annular grooves 106, that is, the friction contact between the friction ring bodies 107 and the annular grooves 106 is adopted, so that the contact stability of the claw body 8 and the metal piece to be cut is realized.
Then, in the design of the driving assembly 7, the driving assembly 7 comprises a plurality of pneumatic cylinders 71, the pneumatic cylinders 71 are uniformly arranged at the circumference of the bottom of the middle platform body 102, the end parts of the piston push rods 72 of the pneumatic cylinders 71 are connected to the middle platform body 102 along the tangential direction of the middle platform body 102, the end parts of the pneumatic cylinders 71 far away from the middle platform body 102 are fixedly connected to the lower platform body 103, wherein the pneumatic cylinders 71 synchronously work to drive the middle platform body 102 to rotate around the fixing rods 104, so that the middle platform body 102 is driven to rotate.
The surface of the middle table body 102 contacting the upper table body 101 is uniformly distributed with a plurality of arc grooves 73 along the radial direction of the surface, the arc grooves 73 extend from the circumferential edge of the middle table body 102 to the center of the middle table body 102, and the claw body 8 is slidably mounted in the arc grooves 73. The projections of the arc-shaped groove 73 and the guide groove 2 in the longitudinal direction are crossed, and the claw body 8 is always positioned at the intersection of the arc-shaped groove 73 and the guide groove 2, so that the claw body 8 is not fixedly connected with the driving assembly 7, but is limited by the arc-shaped groove 73 and the guide groove 2 at the same time, and the clamping stability of the claw body 8 is ensured.
The main working principle of the driving of the claw body 8 is that, as the middle platform body 102 rotates under the driving of the pneumatic cylinder 71, the guide groove 2 is fixed, so that the claw body 8 moves along the arc-shaped groove 73 under the guiding restriction of the guide groove 2 (namely, the projection intersection point of the arc-shaped groove 73 and the guide groove 2 is constantly changed due to the middle platform body 102).
Because the claw body 8 needs to synchronously slide in the arc-shaped groove 73 and the guide groove 2, the invention further designs the claw body 8 which meets the sliding requirement, the claw body 8 comprises a sliding seat 81 matched with the guide groove 2, the bottom of the sliding seat 81 is provided with a shaft body 82 extending into the arc-shaped groove 73, and the tail end of the shaft body 82 is provided with a lantern ring 83 in a rolling way; of course, the contact type of the sliding seat 81 and the guide groove 2 is preferably rolling contact, and does not depart from the guide groove 2, and the contact of the same collar 83 with the arc-shaped groove 73 is also rolling contact, and does not depart from the arc-shaped groove 73.
The whole connecting body of the sliding seat 81 and the shaft 82 forms an angle of 70-90 degrees with the horizontal plane, so that the claw body 8 can clamp the surface of the metal piece to be cut at a certain angle, namely, the horizontal component force along the metal piece to be cut is increased, the clamping force is improved, and the clamping stability is ensured.
Further, in order to improve stability of the claw body 8 when moving along the arc-shaped groove 73 and the guide groove 2, a plurality of guide rods 108 are arranged on the upper surface of the middle platform body 102, the guide rods 108 are in one-to-one correspondence with the arc-shaped grooves 73, one end of each guide rod 108 is arranged on the circle center position of the middle platform body 102 through a rotating shaft seat 109, and the other end of each guide rod 108 penetrates through the shaft body 82 along the radial direction of the shaft body 82, so that the acting force direction of the claw body 8 is limited to 3, specifically, the length direction of the guide groove 2, the length direction of the guide rod 108 and the circle center direction of the arc-shaped groove 73, and the intersection point of the extension lines of the three directions is the position of the claw body 8;
of course, in order to accommodate the restriction in three directions and the change in position, the shaft 82 of the pawl 8 needs to be rotatably connected to the slide mount 81.
Further, in the invention, in order to lock the metal piece at any position by the claw body 8 in the process of matching with the driving state of the pneumatic cylinder 71 to the middle table body 102, the middle table body 102 can also lock at any position to ensure the stability of clamping the metal piece by the claw body 8.
Further, in order to achieve stable clamping of the claw body 8 when the claw body 8 is in contact with the surface of the metal piece to be cut at any position (matched with the arc-shaped shell 4), and the middle table body 102 can be locked, the end part of the piston push rod 72 of the pneumatic cylinder 71 is connected with the middle table body 102 through the elastic piece 9. The elastic piece 9 comprises a guide sleeve 91 fixedly connected with a middle platform body 102, a guide shaft 92 is sleeved in the guide sleeve 91, one end of the guide shaft 92 is hinged with the end of the piston push rod 72, the other end of the guide shaft 92 extending out of the guide sleeve 91 is provided with a stop pad 93, and a spring 94 is sleeved on the guide shaft 92 between the stop pad 93 and the guide sleeve 91. The bottom of middle stage body 102 rotates and installs driving disk 95, and driving disk 95's peripheral edge is connected with the junction of guiding axle 92 and piston push rod 72 through connecting piece 98, and driving disk 95's centre of a circle department is provided with locking circle 96, and locking circle 96 cup joints with dead lever 104, and locking circle 96's surface and middle stage body 102 threaded connection, locking circle 96's inner circle is provided with along locking circle 96 axial protruding 97, and protruding 97 increases along locking circle 96's axial height gradually.
In a specific implementation process, the piston push rod 72 of the pneumatic cylinder 71 pushes the guide shaft 92 to move along the guide sleeve 91 during the extension action, at this time, the guide shaft 92 compresses the spring 94 through the stop pad 93, and force is applied to the guide sleeve 91, so that the pneumatic cylinder 71 drives the middle table 102 to rotate around the fixed rod 104, at this time, the claw body 8 is not in contact with the metal piece, and at this time, the transmission disc 95 and the middle table 102 synchronously rotate.
When the claw body 8 contacts with the metal piece to be clamped and clamping is completed, the position of the claw body 8 cannot move in the guide groove 2 and the arc-shaped groove 73, the piston push rod 72 of the pneumatic cylinder 71 continues to perform extension action, namely, the stop pad 93 further compresses the spring 94, the middle table body 102 stops rotating, the guide shaft continues to move along the guide sleeve 91, the piston push rod 72 pushes the transmission disc 95 to rotate through the connecting piece, the transmission disc 95 rotates relative to the middle table body 102 at the moment, the locking ring 96 and the middle table body 102 are spirally combined, the locking ring 96 moves along the axial direction of the fixed rod 104, the protrusion 97 contacts with the surface of the fixed rod 104, and acting force along the radial direction of the fixed rod 104 is generated.
In the above process, the transmission disk 95 has a certain movement space in the axial direction of the intermediate stage 102.
In the invention, the middle table body 102 and the fixing rod 104 can be locked in the mode, and simultaneously, the lower surfaces of the middle table body 102 and the upper table body 101 can be tightly contacted, so that the contact friction force between the friction ring body 107 and the ring groove 106 between the middle table body 102 and the upper table body 101 is increased; thus, no matter where the claw body 8 and the metal piece to be cut are located on the upper stage body 101, and how the shape of the metal piece to be cut with the tape is, the intermediate stage body 102 can be locked in position after the claw body 8 completes the clamping action.
It is added that the friction ring body 107 and the ring groove 106 are provided on a surface near the circumferential edge of the structure.
Further, the guide groove 2 in the present invention specifically includes a straight groove body structure or a convex arc groove body structure provided in the radial direction of the upper stage body 101.
