Description

TECHNICAL FIELD

[0001] The utility model belongs to power battery technical field, especially, a kind of cleaning mechanism and its tool for high-efficiency cleaning hole welding slag.

BACKGROUND

[0002] In recent years, with the continuous improvement of scientific and technological level, and the increasing attention of countries around the world to energy problems, power batteries have been widely used in various industries due to their high power, high energy density and safety and reliability. However, while power batteries are widely used in various industries, there are still difficulties in their production process. When the battery box floor is welded with multiple screws, the welding points are dense and the splashing is large, which can cause a large amount of welding slag in the holes of the parts. The anti-splashing baffle cannot effectively prevent the welding slag. In order to ensure that the next process is not affected, the staff needs to use tools to clean the welding slag in each hole of the part. Since there are too many holes in a single part, the staff cannot guarantee that each hole is cleaned, resulting in a large number of defective products.

[0003] The patent with publication number CN 219852408 U discloses a tool for removing welding slag, which includes a handle, a vertical rod, a file, a knocking mechanism and a jet mechanism. The rear end of the handle is connected to the jet mechanism for blowing off the knocked-off welding slag. The front end of the handle is fixedly connected to the vertical rod. The top end of the vertical rod is provided with the file. The lower part of the vertical rod is connected to the knocking mechanism. This scheme provides a welding slag removal tool suitable for removing welding slag from the surface of a welded workpiece. If used to remove welding slag from multiple holes, it can only be cleaned one by one, which is low in efficiency and may result in missed cleaning.

[0004] The patent with publication number CN202517137U discloses a device for removing welding slag from the inner hole of a flange pipe, which includes a bidirectional pump. The pump is connected to hydraulic lines a and b. The flange of the flange pipe overlaps the flange of the cylinder body of the device and is fixed to the cylinder body by a connecting half sleeve installed on the outer edge of the flange. This scheme fixes the cylinder body and the flange of the flange pipe to be cleaned into one body by the connecting half sleeve to realize the forward and backward movement of the piston rod in the cylinder body, which drives the cutting head to smoothly cut the welding slag on the inner wall of the flange pipe. Similarly, this scheme can only clean one by one, which is low in efficiency and may result in missed cleaning.

[0005] Therefore, it is necessary to provide a cleaning mechanism and its tool for high-efficiency cleaning hole welding slag to solve the above technical problems.
