Technical Field

[0001] The utility model relates to the technical field of gearboxes, in particular to a painting device for processing automobile gearbox covers. Background Technique

[0002] The gearbox, as a core component of an automobile, is mainly divided into two categories: manual and automatic. The structure of a manual gearbox mainly consists of gears and shafts, and its working principle is to achieve changes in speed and torque through different gear combinations. Relatively speaking, an automatic gearbox is more complex. It consists of a hydraulic torque converter, planetary gears, a hydraulic variable pitch system, a hydraulic control system, and other components, and achieves the effects of speed change and torque change through hydraulic transmission and precise gear combinations.

[0003] The gearbox plays a crucial role in a vehicle. It can flexibly change the transmission ratio, thereby increasing the torque of the driving wheels and regulating their speeds. The rapid development of technology has also driven the innovation of gearboxes. From the early manual gearboxes to the current continuously variable transmissions, and from the design without a synchronizer to the design with a synchronizer, the operation of drivers has become more convenient.

[0004] Before the gearbox is installed in a vehicle, in order to ensure the durability and corrosion resistance of its appearance, it is usually necessary to spray paint on its surface. However, due to the often irregular shape of the gearbox, there may be inaccessible dead corners during the spraying process, and insufficient spraying in these areas may affect the service life of the gearbox. Therefore, we propose a painting device for processing automobile gearbox covers that is convenient to achieve uniform covering spraying to solve the above problems. Content of the Utility Model
