Machining device for automobile swing arm

Abstract

The invention discloses a machining device for an automobile swing arm, and relates to the technical field of automobile part machining. The machining device comprises a conveying system, a power connection assembly, a suspension assembly, an upper rail, a lower rail and a rail electrode. According to the machining device, by arranging different rails and being assisted by the power connection assembly of a special structure, power-off groove entering of products can be smoothly achieved,. a contact rod is ensured to work only when entering an electrophoretic coating process, the contact rod can be ensured not to be polluted in other processes by arranging a sealing cover, and the product quality caused by poor contact is avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile parts processing, and in particular relates to a processing device for an automobile swing arm. Background technique [0002] The car swing arm is the connection mechanism between the frame and the wheel, which plays a vital role in maintaining the stability of the vehicle. It needs to be coated with a layer of paint on its surface in the final processing process. The current mainstream coating method is The use of electrophoretic spraying is mostly realized through continuous automated electrophoretic coating production lines. For this kind of production line, the method of charging into the tank is often used, but charging into the tank will cause ladder-like defects on the coating film on the product. Currently, for power-off tank ( That is, the production line where the workpiece to be coated is completely immersed in the electrophoretic paint and then powered) is rare, part of the reason i...

[0002] The car swing arm is the connection mechanism between the frame and the wheel, which plays a vital role in maintaining the stability of the vehicle. It needs to be coated with a layer of paint on its surface in the final processing process. The current mainstream coating method is The use of electrophoretic spraying is mostly realized through continuous automated electrophoretic coating production lines. For this kind of production line, the method of charging into the tank is often used, but charging into the tank will cause ladder-like defects on the coating film on the product. Currently, for power-off tank ( That is, the production line where the workpiece to be coated is completely immersed in the electrophoretic paint and then powered) is rare, part of the reason is that the power connection part is exposed to the production environment for a long time, and the conductive contact will be polluted after multiple processes, resulting in poor power connection , which in turn causes the input current of the product to fluctuate, affecting product quality. In addition, if the power connection device adopts electric drive, each suspension component needs to carry a backup power supply. Considering the problem of charging, the production continuity is poor
