Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping device for mechanical automation with anti-pressure damage function. Background Technology

[0002] Machine tool fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They contact the positioning reference of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the correct relative position of the workpiece with respect to the cutting tool and the machining motion of the machine tool during processing. Using fixtures to clamp workpieces is convenient and fast, and can significantly reduce auxiliary time. Fixtures are commonly used in mechanical automation to facilitate the clamping and fixing of workpieces.

[0003] When using a clamp to hold a workpiece, two sets of clamping plates are usually moved in opposite directions to hold the workpiece. To prevent excessive force from damaging the workpiece, springs and rubber pads are usually used. However, springs and rubber pads are easily damaged after prolonged use. Since they are usually fixed to one side of the clamping plates, they are difficult to replace. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Refer to Figure 1-5This utility model provides a technical solution: a clamp for mechanical automation with anti-pressure injury function, including a workbench 1. A movable plate 5 is mounted on one side of the workbench 1 via a first moving mechanism. The first moving mechanism includes a motor 2 fixedly mounted on one side of the workbench 1. A first bidirectional threaded rod 3 is fixedly mounted on the output end of the motor 2. A first moving block 4 is threadedly fitted onto the surface of the first bidirectional threaded rod 3. The top of the first moving block 4 and the bottom of the movable plate 5 are fixedly mounted to facilitate the movement of the movable plate 5. A T-shaped groove 6 is formed on the top of the movable plate 5. A T-shaped block 7 is slidably mounted on the inner wall of the T-shaped groove 6. A first mounting groove 8 is formed on one side of the T-shaped block 7. A first mounting post 11 is mounted inside the movable plate 5 via a second moving mechanism. The second moving mechanism includes a second bidirectional threaded rod 9 rotatably mounted inside the movable plate 5. The surface of the threaded rod 9 is threaded with a second moving block 10. One side of the second moving block 10 and one end of the first mounting post 11 are fixedly installed to facilitate the movement of the first mounting post 11. The inside of the moving plate 5 is provided with a sliding groove 25. The inner wall of the sliding groove 25 is in contact with the surface of the second moving block 10 to limit the movement of the second moving block 10, making the movement of the second moving block 10 more stable. One side of the T-shaped block 7 is fixedly installed with a connecting plate 12 to facilitate the positioning of the connecting plate 12. One side of the connecting plate 12 is fixedly installed with a telescopic rod 13 and a first spring 14. One end of the first spring 14 is fixedly installed with a mounting plate 15. The top of the mounting plate 15 is provided with a positioning groove 16. The inner wall of the positioning groove 16 is slidably installed with a positioning block 17. One side of the positioning block 17 is provided with a second mounting groove 18. The inside of the mounting plate 15 is provided with a slot 19.

[0024] Specifically, a second mounting post 23 is installed inside the slot 19 via a reset mechanism. The reset mechanism includes a sliding post 20 slidably mounted on the inner wall of the slot 19. A sliding plate 22 is fixedly mounted at one end of the sliding post 20. A second spring 21 is fixedly mounted on the inner wall of the slot 19. One end of the second spring 21 is fixedly mounted to one side of the sliding plate 22. One side of the sliding plate 22 is fixedly mounted to one end of the second mounting post 23, facilitating the movement of the second mounting post 23. The inner wall of the first mounting slot 8 mates with the surface of the first mounting post 11. The inner wall of the second mounting slot 18 mates with the surface of the second mounting post 23. A rubber pad 24 is fixedly mounted on one side of the positioning block 17, facilitating the positioning of the rubber pad 24. There are two sets of first moving blocks 4 and moving plates 5 arranged symmetrically. There are also two sets of mounting plates 15 and rubber pads 24 arranged symmetrically. The reset mechanism drives the second mounting post 23... Once the mounting post 23 leaves the inner wall of the second mounting groove 18, the limiting installation of the positioning block 17 can be released, and the rubber pad 24 can be removed. Then, the positioning block 17 on one side of the new rubber pad 24 is inserted into the inner wall of the positioning groove 16. The reset mechanism drives the second mounting post 23 to be inserted into the inner wall of the second mounting groove 18, which limits the rubber pad 24 and facilitates its replacement. The second moving mechanism drives the two sets of first mounting posts 11 to leave the inner wall of the first mounting groove 8, which releases the limiting of the connecting plate 12. Then, the telescopic rod 13 and the first spring 14 can be removed. Then, the new T-shaped block 7 is inserted into the inner wall of the T-shaped groove 6. The second moving mechanism drives the two sets of first mounting posts 11 to be inserted into the inner wall of the first mounting groove 8, which installs the connecting plate 12 and then the telescopic rod 13 and the first spring 14, facilitating their replacement.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0026] In use: When using this mechanical automation fixture with anti-crushing function, the workpiece is placed on top of the worktable 1. The motor 2 drives two sets of first bidirectional threaded rods 3 to rotate. The first bidirectional threaded rods 3 drive two sets of first moving blocks 4 to move in opposite directions. The first moving blocks 4 drive two sets of moving plates 5 to move in opposite directions. The moving plates 5 drive two sets of rubber pads 24 to move in opposite directions, thus clamping the workpiece. The cooperation of the telescopic rod 13, the first spring 14, and the rubber pads 24 prevents crushing of the workpiece. The motor 2 drives the two sets of rubber pads 24 to move in opposite directions, thus releasing the workpiece for easy removal. By pulling the sliding column 20, the sliding plate 22 is moved. The sliding plate 22 drives the second mounting column 23 away from the inner wall of the second mounting groove 18, thus releasing the limiting installation of the positioning block 17 and removing the rubber pad 24. Then, the positioning block 17 on one side of the new rubber pad 24 is inserted into the inner wall of the positioning groove 16. The second spring 21 resets and moves the slide plate 22. The slide plate 22 moves the second mounting post 23 into the inner wall of the second mounting groove 18, which limits the rubber pad 24 and facilitates its replacement. By rotating the second bidirectional threaded rod 9, the two sets of second moving blocks 10 move in opposite directions. The second moving blocks 10 move the two sets of first mounting posts 11 away from the inner wall of the first mounting groove 8, which releases the limit of the connecting plate 12. Then, the telescopic rod 13 and the first spring 14 can be removed. A new T-shaped block 7 is then inserted into the inner wall of the T-groove 6. By rotating the second bidirectional threaded rod 9, the two sets of first mounting posts 11 are inserted into the inner wall of the first mounting groove 8, which allows the connecting plate 12 to be installed. Then, the telescopic rod 13 and the first spring 14 can be installed, which facilitates the replacement of the telescopic rod 13 and the first spring 14. This achieves the purpose of facilitating the replacement of the telescopic rod 13, the first spring 14, and the rubber pad 24. The structure is simple and easy to use.
