DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-9The present invention provides a technical solution: a clamping tool for processing cemented carbide plates, a plate placement groove 2 is arranged on one side of a mounting platform 1, and an L-shaped electric slide rail 3 is installed above the mounting platform 1 and the plate placement groove 2, an electric slider 301 used in conjunction with the L-shaped electric slide rail 3 is installed inside the L-shaped electric slide rail 3, and the electric slider 301 is connected to a hydraulic rod 303 through a connecting block 302, and the hydraulic rod 303 can drive a suction cup positioning mechanism 4 to perform lifting operations, a positioning plate 5 used in conjunction with the suction cup positioning mechanism 4 is slidably arranged above the mounting platform 1, and a clamping plate mechanism 6 is installed on the top of the positioning plate 5.

[0036] Specifically, the suction cup positioning mechanism 4 includes a first mounting plate 401, and two groups of first connecting members 402 are arranged at the bottom of the first mounting plate 401, a first rotating column is rotatably arranged between the first connecting members 402, and the outer side of the first rotating column is connected to the first mounting block 404 arranged on the top of the second mounting plate 403, two groups of second connecting members 405 are arranged at the bottom of the first mounting plate 401, and a second rotating column is rotatably arranged between the second connecting members 405, one end of the second rotating column is connected to the first driving motor 406 arranged on the outer side of the second connecting member 405, and an anti-rotation device is installed at the output end of the first driving motor 406. The anti-rotation device is a prior art and will not be described in detail. By arranging the anti-rotation device, the second rotating column can be prevented from being rotated on the plate The second rotating column rotates under the action of weight, and the outer side of the second rotating column is movably connected with the second mounting block 408 arranged on the top of the second mounting plate 403 through a V-shaped telescopic connecting arm 407. The V-shaped telescopic connecting arm 407 includes a first connecting arm, and one end of the first connecting arm is movably connected with the second connecting arm. A side plate 7 is arranged on one side of the second mounting plate 403, and two groups of driving rods 701 are installed on the outer side of the side plate 7, and a stop block 702 is arranged on the inner side of the two groups of driving rods 701. The height of the driving rod 701 is greater than the stop block 702. Two groups of driving rod inserts 8 used in conjunction with the driving rod 701 are fixedly arranged on the top of the positioning plate 5. A vacuum tube 4031 is arranged inside the second mounting plate 403, and the vacuum tube 4031 is connected to the vacuum tube 4031 and the vacuum tube 4031 is arranged at the bottom of the second mounting plate 403. The suction cup 4032 is connected to the suction cup 4032, one end of the vacuum tube 4031 is connected to the vacuum pump 4033 arranged on the top of the outer side of the second mounting plate 403 through the exhaust pipe, the vacuum tube 4031 is connected to the exhaust pipe 4034, one end of the exhaust pipe 4034 runs through the outer side of the second mounting plate 403, and an electric valve matching it is installed inside the exhaust pipe 4034. By setting the exhaust pipe 4034, it is easy to change the vacuum state of the vacuum suction cup 4032, so that the vacuum suction cup 4032 no longer absorbs objects. When in use, under the action of the L-shaped electric slide rail 3 and the electric slider 301, the vacuum suction cup 4032 moves to the top of the plate placement slot 2, and the hydraulic rod 303 drives the vacuum suction cup 4032 to descend. When the vacuum suction cup 4032 is in contact with the plate placement slot 2, the hydraulic rod 303 drives the vacuum suction cup 4032 to descend. When the top plate in the slot 2 contacts, the vacuum pump 4033 is turned on. Under the action of the vacuum pump 4033, the gas inside the vacuum suction cup 4032 is extracted, so that the vacuum suction cup 4032 is adsorbed and connected with the top of the plate. At this time, the plate is moved to the top of the positioning plate 5 by the action of the L-shaped electric slide rail 3 and the electric slider 301. After the placement is completed, the hydraulic rod 303 drives the second mounting plate 403 to move up. After moving up to a certain height, the first driving motor 406 is turned on. Under the action of the first driving motor 406, the second mounting plate 403 is driven to rotate around the first connecting piece 402 through the V-shaped telescopic connecting arm 407. When the second mounting plate 403 rotates 90 degrees, the driving rod 701 is vertically located above the driving rod insert 8.The hydraulic rod 303 is turned on to insert the driving rod 701 into the driving rod inserting tube 8 and the stopper 702 does not contact the top of the plate. At this time, the positioning plate 5 and the plate clamped above the positioning plate 5 can be driven to move horizontally through the L-shaped electric slide rail 3 and the electric slider 301. When the positioning plate 5 does not need to move, the L-shaped electric slide rail 3 and the electric slider 301 are closed, and the hydraulic rod 303 is turned on again to drive the stopper 702 to move downward so that the stopper 702 presses down the plate, thereby limiting the position of the plate and the positioning plate 5 to a certain extent.

[0037] Specifically, the drive rod insert 8 includes an open cylinder 801, and the bottom of the open cylinder 801 is fixedly connected to the top of the positioning plate 5. A movable plate 802 is arranged inside the open cylinder 801. The movable plate 802 is slidably connected to the inside of the open cylinder 801, and the bottom of the movable plate 802 is connected to the inner bottom of the open cylinder 801 through a symmetrically arranged spring 803. When the stop block 702 contacts the top of the plate, the spring 803 is in a compressed state. Under the influence of the reaction of the spring 803, downward pressure can be applied to the positioning plate 5, thereby playing a certain positive role in limiting the position of the positioning plate 5.

[0038] Specifically, the clamping plate mechanism 6 includes a second drive motor 601, and the second drive motor 601 is installed on the outside of the positioning plate 5. A mounting groove is opened inside the positioning plate 5, and a gear 602 is arranged inside the mounting groove. The second drive motor 601 can drive the gear 602 to rotate, and the gear 602 is meshed with two sets of rack plates 603. One end of the rack plate 603 is fixedly connected to the first slider 604, and the first slider 604 is connected to the second slider 606 through a connecting rod 605. The top of the second slider 606 is connected to the clamping plate 608 slidably arranged on the top of the positioning plate 5 through a connecting rod 607, and a movable through groove used in conjunction with the connecting rod 607 is opened on the positioning plate 5.

[0039] Further explanation: a first transverse limit slide bar 9 is symmetrically arranged inside the installation groove, and the first transverse limit slide bar 9 is slidably connected to the first slider 604. By setting the first transverse limit slide bar 9, the moving direction of the first slider 604 can be limited, thereby improving the stability of the first slider 604 when moving. The second slider 606 moves in the moving groove opened in the positioning plate 5, and the second slider 606 is slidably connected to the second transverse limit slide bar 10 symmetrically arranged in the moving groove. By setting the second transverse limit slide bar 10, the moving direction of the second slider 606 can be limited, thereby improving the stability of the second slider 606 when moving.

[0040] When it is necessary to clamp and limit the plate placed above the positioning plate 5, the second drive motor 601 is turned on, and the gear 602 rotates under the action of the second drive motor 601. The gear 602 rotates to drive the two sets of rack plates 603 to move, thereby driving the second slider 606 to move through the first slider 604 and the connecting rod 605. Under the action of the movement of the second slider 606, the connecting rod 607 drives the clamping plate 608 to move synchronously, and the two sets of clamping plates 608 continue to approach each other to clamp and limit the plate placed inside.
