[0029] A punch assembly and positioning assembly includes a connecting ring 1, four conical plates 3 are installed on the top of the connecting ring 1, a threaded ring 4 is provided at the bottom of the conical plate 3, a positioning ring 5 is provided inside the threaded ring 4, and two clamping devices 7 are provided inside the connecting ring 1 for clamping the punch 2;

[0030] The clamping device 7 includes rack 1 701, rack 2 704, wedge 1 705, wedge 2 706, gear 702, fixed shaft 703, two springs 709, two positioning shafts 708, slider 707 and arc plate 7010. Rack 1 701 and rack 2 704 are connected to gear 702, the fixed shaft 703 passes through gear 702, wedge 1 705 is connected to rack 2 704, wedge 2 706 is connected to slider 707, the positioning shaft 708 is connected to slider 707, the spring 709 is passed through the positioning shaft 708, and the slider 707 is connected to the arc plate 7010.

[0031] In this example, two clamping devices 7 are symmetrically installed inside the connecting ring 1, and a hole that matches it is provided inside the connecting ring 1. A protruding shaft is provided at the bottom of the positioning ring 5 for connecting to the rack 701. The positioning ring 5 is rotatably connected to the threaded ring 4, and the positioning ring 5 is located inside the threaded ring 4.

[0032] It should be noted that the symmetrical installation layout of the two clamping devices 7 helps to balance the torque and ensure uniform distribution of the clamping force. The positioning ring 5 and the threaded ring 4 are connected by rotation, so that the positioning ring 5 can rotate freely inside the threaded ring 4.

[0033] In this example, rack 1 701 is fixedly connected to the protruding shaft 6 at the bottom of the positioning ring 5, gear 702 is rotatably connected to the fixed shaft 703, and gear 702 is installed inside the connecting ring 1 through the fixed shaft 703, the bottom of rack 2 704 cooperates with gear 702, wedge 1 705 is installed on the toothless side of rack 2 704, and wedge 1 705 is installed on the top of rack 2 704.

[0034] It should be noted that rack 1 701 and the protruding shaft 6 at the bottom of the positioning ring 5 are fixedly connected to ensure stable transmission between rack 1 701 and the positioning ring 5. Rack 2 704 cooperates with gear 702 to realize the rotation of gear 702 to drive rack 2 704 to perform linear motion.

[0035] In this example, wedge block 2 706 is installed in the middle position of the back of slider 707. Slider 707 is T-shaped, and the middle part of slider 707 is hollowed out. The inner ring of connecting ring 1 is provided with a through hole that matches slider 707. The front end of slider 707 is connected to arc plate 7010.

[0036] It should be noted that wedge block 2 706 is installed in the middle position of the back of slider 707. Such a layout helps to balance the movement of slider 707. The through hole set in the inner ring of connecting ring 1 allows slider 707 to move freely inside connecting ring 1 while maintaining a firm connection with connecting ring 1.

[0037] In this example, two positioning shafts 708 are symmetrically installed at the upper and lower ends of the slider 707, and two protruding shafts 6 are provided inside the connecting ring 1 to limit the movement of the positioning shafts 708. The positioning shafts 708 pass through the slider 707, and the spring 709 is located between the protruding shafts 6 inside the connecting ring 1 and the slider 707.

[0038] It should be noted that the function of the positioning shaft 708 is to ensure that the slider 707 maintains the correct position during movement, thereby ensuring the accuracy of the punch 2 assembly. The spring 709 provides a certain buffer during the movement of the slider 707 to improve the stability and reliability of the system.

[0039] In this example, the four conical plates 3 are arc-shaped, and the outer rings of the four conical plates 3 are provided with external threads that match the threaded ring 4. The threaded ring 4 is threadedly connected to the bottom of the conical plates 3, and the inner rings of the four conical plates 3 are expanded.

[0040] It should be noted that the arc plate 7010 is designed to match the shape of the punch 2 to provide better contact and positioning during the assembly process. By cooperating with the threaded ring 4, the conical plate 3 can provide precise positioning and stable clamping.

[0041] To summarize: When the punch 2 needs to be clamped, first, pass the punch 2 through the connecting ring 1 and the conical plate 3 at the top. Next, tighten it upward along the thread of the outer ring of the conical plate 3. This action will cause the conical plate 3 to gradually move inward under the push of the threaded ring 4, thereby achieving the clamping and positioning of the punch 2. As the threaded ring 4 rises, the internal positioning ring 5 will also push the rack 1 701 upward along the axis, causing the gear 702 to start rotating and drive the rack 2 704 to move downward. When the rack 2 704 moves downward, the wedge 1 705 on its back will push the wedge 2 706 outward. The outward movement of the wedge 2 706 pushes the arc plate 7010 outward through the slider 707, ultimately achieving a firm clamping of the punch 2 located inside the connecting ring 1. Every component in this process works together precisely to ensure the accuracy and safety of the operation.

[0042] Beneficial effects:

[0043] The punch assembly and positioning component, through the design of rack 1 and point positioning ring, enables the clamping device and the conical plate on the top of the connecting ring to cooperate. In the process of clamping the punch, the operator only needs to tighten the threaded ring upward along the thread of the outer ring of the conical plate to easily achieve the assembly and positioning of the punch. The function of the clamping device is further enhanced by the design of wedge block 1 and wedge block 2, so that the clamping device can clamp the punch quickly and firmly.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
