Description

Technical Field

[0001] This utility model relates to the field of chamfering device technology, specifically a copper busbar punching and chamfering die. Background Technology

[0002] Chamfering and punching holes in copper busbars is a metalworking process primarily used in the processing of copper busbars in power and electrical equipment. Chamfering involves grinding the edges of holes in the copper busbar to remove sharp edges, preventing injury to personnel or damage to other components during use. Chamfering and punching holes in copper busbars improves installation efficiency and safety, and also contributes to enhanced reliability of electrical connections.

[0003] Traditional devices for punching and chamfering copper busbars have low flexibility. When multiple holes need to be chamfered after the copper busbar is fixed, the chamfering device is not easy to move at multiple points, which makes it inconvenient to use. Therefore, it is necessary to develop a copper busbar punching and chamfering mold. Utility Model Content

[0044] One end of the positive and negative double-headed lead screw 107 extends and rotatably passes through the side wall of a fixed plate 106 and is equipped with a handwheel 108.

[0045] The copper busbar to be processed is placed on two pads 102.

Example

[0046] Based on Embodiment 1, the first driving mechanism includes a ring gear 206 fixedly disposed on the bottom wall of the rotating plate 200 in an annular shape, and a vertical servo reduction motor 207 fixedly disposed on the side wall of the support column 101. The output shaft of the servo reduction motor 207 is provided with a gear 208 that meshes with the ring gear 206.

[0047] Start the servo geared motor 207, which drives the rotating plate 200 to rotate through the gear 208 and the gear ring 206. Example

[0048] Based on Embodiment 1, the second driving mechanism includes a first opening 209 opened on the upper and lower walls of the rotating plate 200. The opening direction of the first opening 209 is consistent with the moving direction of the U-shaped frame 201, and the upper end of the U-shaped frame 201 slides and penetrates the first opening 209.

[0049] Mounting plates 210 are symmetrically arranged on both sides of the top of the rotating plate 200 above the first opening 209. A first lead screw 211 parallel to the first opening 209 is rotatably arranged between the side walls of the two U-shaped frames 201. The first lead screw 211 is screwed through the side wall of the rotating U-shaped frame 201.

[0050] A servo geared motor 212 is fixedly installed on the top of the rotating plate 200. The output shaft of the servo geared motor 212 is connected to the end of the first lead screw 211 through a coupling.

[0051] The third driving mechanism includes a second opening 213 on the upper and lower walls of the U-shaped frame 201. The opening direction of the second opening 213 is consistent with the moving direction of the convex frame 202, and the upper end of the convex frame 202 slides and passes through the second opening 213.

[0054] When it is necessary to adjust the chamfering tool 205, the servo geared motor 212 can be started to drive the first lead screw 211 to rotate, so that the U-shaped frame 201 moves along the first opening 209, thereby adjusting the position of the chamfering tool 205. Alternatively, the servo geared motor 215 can be used to drive the second lead screw 214 to rotate, so that the convex frame 202 moves along the second opening 213, which also serves to adjust the position of the chamfering tool 205.

[0055] In practical use, the copper busbar to be processed is placed on two pads 102. The handwheel 108 drives the double-headed screw 107 to rotate, thereby adjusting the distance between the two pads 102 so that the two clamping plates 103 clamp the copper busbar on the left and right sides to clamp and fix the copper busbar.

[0056] When the chamfering tool 205 needs adjustment, the servo reducer motor 212 can be started to rotate the first lead screw 211, causing the U-shaped frame 201 to move along the first opening 209, thereby adjusting the position of the chamfering tool 205. Alternatively, the servo reducer motor 215 can be started to rotate the second lead screw 214, causing the convex frame 202 to move along the second opening 213, which also adjusts the position of the chamfering tool 205. In combination with starting the servo reducer motor 207, the rotating plate 200 can be rotated through the gear 208 and the gear ring 206, which allows the chamfering tool 205 to move at multiple points, making it convenient to chamfer holes at different positions on the copper busbar. Finally, the electric cylinder 203 is started to lower the chamfering tool 205 to contact the hole, and then the chamfering motor 204 is started to rotate the chamfering tool 205 to perform the chamfering operation on the hole.

[0057] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
