[0002] Copper busbar is a high-current conductive product, suitable for electrical engineering projects such as high and low voltage electrical appliances, switch contacts, power distribution equipment, bus ducts, etc. It is also widely used in ultra-large current electrolytic smelting projects such as metal smelting, electrochemical plating, and chemical caustic soda. In the process of copper busbar processing, holes need to be opened at corresponding positions inside the copper busbar to facilitate the subsequent docking between the copper busbars. Therefore, a drilling machine is needed to drill holes in the copper busbar.

Auxiliary handles 404 are fixedly installed on the top of the movable rods 403. A wedge-shaped surface 402 is provided on the side where the auxiliary handle 404 and the limit seat 405 are close to each other. By pulling the auxiliary handle 404, the auxiliary handle 404 can drive the limit plate 408 on the same side to move upward along the guide rod 407, and the auxiliary handle 404 can be elastically moved. The spring 406 will be compressed, and the limit plate 408 and the inner bottom end of the limit frame 401 will separate from each other. Then, the auxiliary handle 404 will be turned, and the wedge surface 402 will be misplaced, so that the movable rod 403 can be temporarily fixed. At the same time, the copper bar to be processed is placed in the limit frame 401, and then the auxiliary handle 404 is turned. The spring 406 will push the limit plate 408 to move downward, so that the copper bar to be processed can be quickly limited.

A plurality of evenly distributed adjustment holes are provided in the middle of the top end of the workbench 1. Since the limiting frames 401 are mounted on the workbench 1 by fixing bolts, when it is necessary to adjust the spacing between the limiting frames 401, the fixing bolts can be used in conjunction with the adjustment holes to adjust the limiting frames 401, which is beneficial for limiting copper bars of different sizes.

[0024] A copper bar drilling assembly 3 is provided at the middle of the top of the workbench 1. A dust removal assembly 2 is provided in the copper bar drilling assembly 3. The copper bar drilling assembly 3 comprises a support frame 301. The support frame 301 is fixedly mounted at the middle of the top of the workbench 1. A hydraulic cylinder 302 is symmetrically fixedly mounted at the top of the support frame 301. A mounting plate 303 is fixedly mounted at the driving end of the hydraulic cylinder 302. A drilling member 304 is fixedly mounted in the middle of the mounting plate 303. The dust removal assembly 2 comprises a plurality of fixed brackets 204. The plurality of fixed brackets 204 are all fixedly mounted at the top of the mounting plate 303. An annular tube 205 is fixedly mounted in the middle of the plurality of fixed brackets 204. A plurality of evenly distributed branch pipes 206 are fixedly mounted at the lower periphery of the annular tube 205. A storage box 201 is fixedly mounted in the middle of one side of the top of the support frame 301. A connecting hose 203 is fixedly installed on one side of the storage box 201 near the middle of the workbench 1. The bottom of the connecting hose 203 is fixedly installed on the surface of the annular tube 205 and is connected to the annular tube 205. A fan 202 is installed on the outer periphery of the connecting hose 203 near the storage box 201. The drilling part 304 can be moved downward by controlling the hydraulic cylinder 302. At this time, the stepping motor and other driving parts in the drilling part 304 can drive the drill bit to rotate, so that the copper busbar can be drilled. While drilling, a large amount of fine impurities will be generated on the surface of the copper busbar. At this time, by controlling the fan 202, the fine impurities generated in the drilling process can be passed through the branch pipe 206, the annular tube 205 and the connecting hose 203 into the storage box 201, so as to avoid tiny metal particles from flying and affecting the health of the staff.

[0025] In actual use, the staff pulls the auxiliary handle 404, at which time the movable rod 403 can move the limit plate 408 upward, and then rotates the auxiliary handle 404 180° clockwise to dislocate the wedge-shaped surface 402 between the limit seat 405 and the auxiliary handle 404. At this time, the auxiliary handle 404 can abut against the upper part of the limit seat 405, and then the staff places the copper bar to be processed on the lower part of the limit plate 408, and then rotates the auxiliary handle 404 180° counterclockwise. At this time, with the cooperation of the spring 406, the limit plate 408 cooperates with the limit frame 401 to limit and fix the copper bar, and at the same time, the wedge-shaped surface 402 between the limit seat 405 and the auxiliary handle 404 The surfaces 402 can overlap, thereby completing the limit fixation of the copper bar. At the same time, the hydraulic cylinder 302 is controlled to drive the drilling member 304 to move downward, so that the copper bar can be drilled. Since there is a certain height difference between the limit frame 401 and the workbench 1, the drilling member 304 can drill the copper bar normally. While drilling, a large number of tiny metal particles will be generated on the surface of the copper bar. At this time, by controlling the fan 202, the tiny metal particles can be passed through the branch pipe 206, the annular pipe 205 and the connecting hose 203 into the storage box 201, and the tiny metal particles can be collected in a centralized manner to avoid the tiny metal particles being inhaled into the body during the copper bar processing, causing damage to the body.
