Description

Technical Field

[0001] This utility model relates to the field of charging box manufacturing technology, and in particular to a welding point grinding device for charging box manufacturing. Background Technology

[0002] With the rapid development of the new energy industry, the production quality of charging boxes, as core equipment for power storage and transmission, directly affects their safety and stability. In charging box production, welding is a crucial step in connecting box components; however, weld points often have defects such as protrusions and burrs, requiring grinding to achieve a smooth surface.

[0003] In existing solder joint grinding devices, the grinding machine drives the grinding head to rotate through the connecting shaft to grind the solder joints of the charging box. During grinding, the metal fragments or powder are ground into metal shavings or powder, which are adsorbed on the surface of the grinding head due to static electricity. The residual impurities are transferred to other solder joints with the grinding head, affecting the grinding quality. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a welding point grinding device for charging box production, which can clean the impurities adsorbed on the grinding head by high pressure gas after a single grinding, prevent the impurities from being transferred to other welding points with the grinding head, and ensure the quality of subsequent grinding.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution: A welding point grinding device for charging box production includes a machine base, a support frame installed at the top of the machine base, the support frame having an inverted L-shaped structure, and a drive mechanism connected to the horizontal end of the support frame. A grinding mechanism is installed at the middle of the bottom end of the drive mechanism, and a stabilizing mechanism is provided at the bottom end of the drive mechanism outside the grinding mechanism. The stabilizing mechanism includes an elastic telescopic rod and a stabilizing plate, and a blowing mechanism is provided on the stabilizing plate. The blowing mechanism includes an annular air passage opened in the stabilizing plate, and multiple sets of high-pressure nozzles are connected to the air passage. The high-pressure nozzles are fixed in an inclined shape on the inner wall of the stabilizing plate, and an external interface is installed on one side of the stabilizing plate, which is connected to the air passage.

[0006] Preferably, the driving mechanism includes a cylinder fixed to the top of the support frame, a piston rod connected inside the cylinder, the piston rod passing through the top of the support frame, and a mounting plate fixed to the bottom end of the piston rod.

[0007] Preferably, the polishing mechanism includes a polishing machine fixed to the bottom end of the mounting plate, a connecting shaft is mounted on the polishing machine, and a polishing head is fixed to the bottom end of the connecting shaft, the polishing head being located above the stabilizing plate.

[0008] Preferably, there are two sets of elastic telescopic rods, and the movable end of the elastic telescopic rod is fixedly connected to the stabilizing plate, which has an annular hollow structure.

[0009] Preferably, guide rods are symmetrically fixed at the top of the mounting plate, the top of the guide rods has a convex structure, and the guide rods are slidably connected to the support frame.

[0010] By adopting the above technical solution, this utility model has the following beneficial technologies: By setting up a blowing mechanism, after the grinding head completes a single pass, the stabilizing plate is reset via the elastic telescopic rod. At this time, the external interface of the blowing mechanism is connected to the external air supply pipeline. High-pressure gas enters the air passage through the external interface and exits through the air passage from the high-pressure nozzle. The high-pressure gas ejected from the high-pressure nozzle can be directly blown towards the grinding head, thereby cleaning the impurities adsorbed on the grinding head and preventing the impurities from being transferred to other welding points with the grinding head, thus ensuring the quality of subsequent grinding.
