Detailed implementation manner

[0026] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments may be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0027] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0028] In the present utility model, unless otherwise stated, the orientations such as "upper, lower" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction; similarly, for the convenience of understanding and description, "left, right" are usually with respect to the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms are not used to limit the present utility model.

[0029] Please refer to Figures 1-5 , a mechanical clamping claw for a numerical control machine tool, including a claw base 1, a clamping claw mechanism is arranged on the claw base 1, the clamping claw mechanism includes an adjusting base 2, an adjusting bolt 3, a clamping claw 4 and a mounting hole 5, multiple groups of adjusting bases 2 are arranged on the claw base 1, multiple groups of adjusting bolts 3 are arranged on the claw base 1, the clamping claw 4 is arranged outside multiple groups of adjusting bases 2, the mounting hole 5 is arranged on the clamping claw 4, a clamping mechanism is arranged on the clamping claw 4, the clamping mechanism includes a clamping rod 6, a clamping groove 7, a clamping sleeve 8, a clamping block 9, an unlocking block 10, an unlocking sleeve 11 and a sliding sleeve 12, the clamping rod 6 is arranged on the adjusting base 2, the clamping groove 7 is arranged on the clamping rod 6, the clamping sleeve 8 is arranged on the clamping claw 4, the clamping block 9 is arranged in the clamping sleeve 8, the unlocking block 10 is arranged at the outer end of the clamping block 9, the unlocking sleeve 11 is arranged on the clamping sleeve 8, and the sliding sleeve 12 is arranged on the outer wall of the unlocking sleeve 11.

[0030] Multiple groups of clamping blocks 9 are slidably installed in the clamping sleeve 8 and the outer ends extend out of the clamping sleeve 8, and multiple groups of unlocking blocks 10 are arranged at the outer ends of multiple groups of clamping blocks 9. This design allows the clamping blocks 9 to slide in the clamping sleeve 8, increasing the flexibility and adaptability of the device. The installation of the unlocking blocks 10 enables unlocking through external operations when needed, improving the operation convenience and safety.

[0031] A telescopic spring 13 is connected between each group of clamping blocks 9 and the clamping sleeve 8. The telescopic spring 13 provides a restoring force, enabling the clamping block 9 to remain stable during sliding, absorbing external force impacts, reducing wear, and extending the service life of the device.

[0032] The top of the unlocking sleeve 11 is provided with an unlocking surface 14, which is set as an inclined surface. The unlocking sleeve 11 is provided with multiple unlocking grooves 15. The inclined unlocking surface 14 and the multiple unlocking grooves 15 improve the smoothness and reliability of the unlocking operation, making the unlocking process more convenient and efficient.

[0033] The clamping sleeve 8 is provided with multiple sliding rods 16, which are slidably connected to the sliding sleeve 12. The design of the sliding rods 16 enables the sliding sleeve 12 to move flexibly to adapt to different working requirements. This sliding connection reduces direct contact, reduces wear, and improves the durability of the device.

[0034] Multiple compression springs 17 are provided at the inner top of the clamping sleeve 8. The compression springs 17 provide stable pressure, ensuring the stability and normal operation of the internal structure of the clamping sleeve 8. The compression springs 17 help protect the internal components when subjected to external force impacts and improve the durability of the device.

[0035] In this embodiment, when installing the jaw 4, the mounting hole 5 provided on the jaw 4 is installed on the clamping rod 6, and then the clamping sleeve 8 is sleeved on the clamping rod 6. When the clamping groove 7 provided on the clamping rod 6 moves to the inside of multiple clamping blocks 9, the telescopic spring 13 pushes the clamping block 9 to be clamped in the clamping groove 7 to clamp and fix the clamping rod 6. At this time, the sliding sleeve 12 is limited by the limiting component, so that the unlocking sleeve 11 cannot be pushed by the pushing spring 24. When it is necessary to disassemble the jaw 4, operate the limiting component to release the limit on the sliding sleeve 12, and push the sliding sleeve 12 to slide along the sliding rod 16 through multiple pushing springs 24. The sliding sleeve 12 pushes the unlocking sleeve 11 so that the unlocking surface 14 provided at its top abuts against both sides of the unlocking block 10. At this time, the unlocking block 10 moves outwards, driving the clamping block 9 to extend out of the clamping sleeve 8. The unlocking sleeve 11 continues to move, causing the clamping block 9 to move into the unlocking groove 15. The two sides of the unlocking groove 15 lift the two sides of the unlocking block 10, causing the locking foot clamping block 9 to move out of the clamping groove 7, releasing the clamping and fixing of the clamping rod 6. Then the clamping sleeve 8 can be detached from the clamping rod 6, and the jaw 4 can be disassembled.

[0036] Please refer to Figure 4, as an implementation of the limit component: A limit component is provided on the clamping sleeve 8. The limit component includes a control sleeve 18, a support rod 19, a limit plate 20, a limit block 21, a mounting plate 22, and a tension spring 23. The control sleeve 18 is rotatably mounted outside the clamping sleeve 8. Multiple groups of support rods 19 are provided on the outer wall of the control sleeve 18. Multiple groups of limit plates 20 are provided on multiple groups of support rods 19. Multiple groups of limit blocks 21 are provided on the outer wall of the sliding sleeve 12. Multiple groups of mounting plates 22 are provided at the top of the clamping sleeve 8. Multiple groups of tension springs 23 are provided between multiple groups of mounting plates 22 and multiple groups of support rods 19. The design of the limit component limits the movement range of the sliding sleeve 12 and prevents equipment damage caused by excessive movement. The adapted design of the spacing between the arc-shaped plates and the limit block 21 ensures the accuracy and smoothness of the limiting operation. The setting of the tension spring 23 provides an additional restoring force and increases the stability of the component.

[0037] Multiple groups of limit plates 20 are all set as arc-shaped plates. The spacing between multiple groups of limit plates 20 is adapted to the limit block 21. Push springs 24 are provided on multiple groups of the sliding rods. The setting of the push springs 24 provides an additional restoring force, enabling the sliding rod 16 to remain stable during the sliding process, reducing wear, and extending the service life of the equipment. The push springs 24 help the sliding rod 16 quickly return to its original position, improving the response speed and working efficiency of the equipment.

[0038] More specifically, after the clamping rod 6 is clamped and fixed by multiple groups of clamping blocks 9, rotate the control sleeve 18 to drive multiple groups of limit plates 20 to rotate to both sides of the limit block 21 and abut against the limit plates 20, so that the sliding sleeve 12 cannot be pushed by the push spring 24. Rotating the control sleeve 18 to drive multiple groups of limit plates 20 to disengage from the limit sleeve can release the limit. The tension spring 23 connected between multiple groups of support rods 19 and the mounting plate 22 can pull the support rod 19 to drive the control sleeve 18 and the limit plate 20 to return to their original positions.

[0039] In summary, when the overall device is in use or running: when installing the clamping jaw 4, install the mounting hole 5 provided on the clamping jaw 4 on the clamping rod 6, and then sleeve the clamping sleeve 8 on the clamping rod 6. When the clamping groove 7 provided on the clamping rod 6 moves to the inner side of the multiple groups of clamping blocks 9, the clamping blocks 9 are pushed to be clamped in the clamping groove 7 by the telescopic spring 13, and the clamping rod 6 is clamped and fixed. At this time, the sliding sleeve 12 is limited by the limiting component, so that the unlocking sleeve 11 cannot be pushed by the push spring 24. When the clamping jaw 4 needs to be disassembled, the limiting component is operated to release the sliding sleeve 12. The limit is set, and the sliding sleeve 12 is pushed along the sliding rod 16 by multiple sets of push springs 24. The sliding sleeve 12 pushes the unlocking sleeve 11 so that the unlocking surface 14 set on its top is connected to the two sides of the unlocking block 10. At this time, the unlocking block 10 moves outward to drive the clamping block 9 to extend out of the clamping sleeve 8. The unlocking sleeve 11 continues to move so that the clamping block 9 moves into the unlocking groove 15, and the two sides of the unlocking groove 15 push up the two sides of the unlocking block 10, so that the locking foot clamping block 9 moves out of the clamping groove 7, releasing the clamping fixation of the clamping rod 6, and then the clamping sleeve 8 can be separated from the clamping rod 6, and the clamping jaw 4 can be disassembled.

[0040] After the clamping rod 6 is clamped and fixed by multiple sets of clamping blocks 9, the control sleeve 18 is rotated to drive the multiple sets of limit plates 20 to rotate to both sides of the limit blocks 21, and the limit plates 20 are abutted, so that the sliding sleeve 12 cannot be pushed by the push spring 24. The control sleeve 18 is rotated to drive the multiple sets of limit plates 20 to disengage from the limit sleeve to release the limit. The tension spring 23 connected between the multiple sets of support rods 19 and the mounting plate 22 can pull the support rod 19 to drive the control sleeve 18 and the limit plate 20 to return to their original position.

[0041] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
