[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] refer to Figures 1 to 5This utility model provides a hydraulic drawing machine jaw replacement structure, including a base plate 1. A mounting sleeve 2 is fixedly connected to the top of the base plate 1. A mounting cavity 3 is formed inside the mounting sleeve 2. Two drive blocks 4 are symmetrically slidably connected inside the mounting cavity 3. A moving block 5 is fixedly connected to one side of each drive block 4. A motion drive assembly for driving the two drive blocks 4 is provided inside the mounting cavity 3. A sliding opening 6 communicating with the outside of the mounting sleeve 2 is formed on one side of the mounting cavity 3. The side of the moving block 5 away from the drive blocks 4 extends to the outside of the mounting sleeve 2 through the sliding opening 6. A disassembly / assembly assembly is provided on the side of the moving block 5 away from the drive blocks 4. A clamping plate 7 is installed inside the disassembly / assembly assembly. The disassembly / assembly assembly includes a clamping plate 7 fixedly connected to the mounting sleeve 2. The moving block 5 has a support plate 8 on the side away from the driving block 4. An L-shaped support 9 is slidably connected to the side of the two support plates 8 that are close to each other. A trapezoidal clip 10 is fixedly connected to the side of the two L-shaped supports 9 that are close to each other. A slot 11 is opened on one side of the clamping plate 7. The trapezoidal clip 10 is slidably engaged in the slot 11. A rotating hole 12 is opened in the L-shaped support 9. A rotating rod 13 is rotatably connected in the rotating hole 12. An internal hexagonal head 14 is fixedly connected to the end of the rotating rod 13 away from the moving block 5. A locking screw 15 is fixedly connected to the end of the rotating rod 13 away from the internal hexagonal head 14. A locking screw hole 16 is opened on the side of the moving block 5 that is close to the L-shaped support 9. The locking screw 15 is threadedly connected in the locking screw hole 16.

[0025] In use, the base plate 1 is installed on the motion module of the hydraulic drawing machine. The clamping plate 7 is locked by the trapezoidal clamping strip 10 and the extended part of the L-shaped support 9. Activating the motion drive assembly drives the two drive blocks 4 to move closer or further apart, thereby clamping or releasing the workpiece using the clamping plate 7. When it is necessary to remove the clamping plate 7, the internal hexagonal head 14 is rotated using a tool, causing the rotating rod 13 to drive the locking screw 15 out of the locking screw hole 16. During this process… The L-shaped support 9 will slide away from the moving block 5, so that the trapezoidal locking strip 10 will gradually slide out of the slot 11. After the trapezoidal locking strip 10 has slid out completely, the clamping plate 7 can be removed. Conversely, when the clamping plate 7 needs to be installed, the slot 11 is aligned with the trapezoidal locking strip 10, and then the locking screw 15 is screwed back into the locking screw hole 16. The trapezoidal locking strip 10 will then be re-engaged into the slot 11, thereby locking the clamping plate 7 in conjunction with the protruding part of the L-shaped support 9.

[0026] This setup allows for quick assembly and disassembly of the clamping plate 7 using the locking screw 15 and locking screw hole 16, effectively improving the assembly and disassembly efficiency of the clamping plate 7 and ensuring the efficient use of the hydraulic drawing machine. Furthermore, by setting the L-shaped support 9, trapezoidal locking strip 10, and locking groove 11, the clamping plate 7 can be stably fixed while improving the ease of assembly and disassembly, thereby further improving the working efficiency of the hydraulic drawing machine.

[0027] Furthermore, a first T-shaped slider 17 is fixedly connected to the side of the L-shaped support 9 near the support plate 8. A first sliding groove 18 is provided on the support plate 8. The first T-shaped slider 17 is slidably connected in the first sliding groove 18. A plurality of limiting posts 19 are fixedly connected to the side of the moving block 5 near the clamping plate 7. A plurality of limiting holes 20 are provided on the side of the clamping plate 7 near the moving block 5. The limiting posts 19 are inserted into the limiting holes 20.

[0028] In use, the first T-shaped slider 17 and the first sliding groove 18 can restrict the rotation of the L-shaped support 9 while ensuring the stable sliding of the L-shaped support 9, thereby effectively improving the sliding effect of the L-shaped support 9 and ensuring the convenient disassembly and assembly of the clamping plate 7. By setting the limiting post 19 and the limiting hole 20, when installing the clamping plate 7, the limiting post 19 can be inserted into the limiting hole 20 first, thereby initially limiting the clamping plate 7 so that the trapezoidal clip 10 can be accurately inserted into the slot 11, thereby further improving the installation convenience and stability of the clamping plate 7.

[0029] Furthermore, the motion drive assembly includes a second sliding groove 21 formed on the bottom surface of the mounting cavity 3, a second T-shaped slider 22 fixedly connected below the drive block 4, the second T-shaped slider 22 being slidably connected within the second sliding groove 21, a drive rod 23 being rotatably connected within the mounting cavity 3, both ends of the drive rod 23 extending to the outside of the mounting sleeve 2, and both ends of the drive rod 23 being fixedly connected to connectors 24, the drive rod 23 having a positive thread 25 and a negative thread 26, and the two drive blocks 4 being threadedly connected to the positive thread 25 and the negative thread 26 respectively.

[0030] In use, the drive rod 23 is connected to an external drive source via the connector 24 to drive the drive rod 23 to rotate. The rotation of the drive rod 23 will drive the two drive blocks 4 to move closer or further apart through the opposite directions of the positive thread 25 and the negative thread 26, thereby clamping or releasing the workpiece. With this setting, the positive thread 25, the negative thread 26 and the drive block 4 can be used to achieve the clamping drive of the clamping plate 7, and the axial locking characteristics of the thread can be used to prevent the clamping plate 7 from loosening, thereby effectively improving the clamping effect of the clamping plate 7.

[0031] It should be noted that the peripheral drive source is preferably a motor, and the above-mentioned clamping method of the clamping plate 7 is only one driving method provided in this application. In actual design and manufacturing, the clamping plate 7 can be clamped and driven by the same hydraulic drive or other driving methods as the prior art.

[0032] Furthermore, anti-slip texture 27 is provided on the side of the two clamping plates 7 that are close to each other, and mounting holes 28 are provided on the base plate 1.

[0033] When in use, the anti-slip texture 27 can further improve the clamping effect of the clamping plate 7, preventing the workpiece from slipping and affecting the normal use of the equipment, while the mounting hole 28 can facilitate the assembly of the equipment with the motion module of the hydraulic drawing machine, thereby using the motion module to perform drawing operations on the workpiece.

[0034] The working principle of this utility model:

[0035] In use, the base plate 1 is installed on the motion module of the hydraulic drawing machine. The clamping plate 7 is locked by the trapezoidal clamping strip 10 and the extended part of the L-shaped support 9. Activating the motion drive assembly drives the two drive blocks 4 to move closer or further apart, thereby clamping or releasing the workpiece using the clamping plate 7. When it is necessary to remove the clamping plate 7, the internal hexagonal head 14 is rotated using a tool, causing the rotating rod 13 to drive the locking screw 15 out of the locking screw hole 16. During this process… The L-shaped support 9 will slide away from the moving block 5, so that the trapezoidal locking strip 10 will gradually slide out of the slot 11. After the trapezoidal locking strip 10 has slid out completely, the clamping plate 7 can be removed. Conversely, when the clamping plate 7 needs to be installed, the slot 11 is aligned with the trapezoidal locking strip 10, and then the locking screw 15 is screwed back into the locking screw hole 16. The trapezoidal locking strip 10 will then be re-engaged into the slot 11, thereby locking the clamping plate 7 in conjunction with the protruding part of the L-shaped support 9.
