Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, specifically to a rust-proof spraying device for bearing parts. Background Technology
[0002] Bearing components are the various parts that make up a bearing, mainly including the inner ring, outer ring, rolling elements, and cage. The inner and outer rings are usually made of high-carbon chromium bearing steel and are processed through forging, turning, grinding, and other processes to obtain high-precision dimensions and surface finish. The rolling elements come in various forms such as steel balls and rollers, and their processing must ensure good roundness and surface quality. The cage is generally made of low-carbon steel or copper alloy and is formed through processes such as stamping and injection molding. Its function is to separate the rolling elements and guide their movement. After these parts are precision machined, they are assembled into bearings to achieve high-precision rotational motion support, and are widely used in various types of mechanical equipment.
[0003] Currently, when manufacturing bearing parts, a spraying device is needed to apply rust-proof coating to the surface of the bearing parts. However, when spraying the edges of the bearing parts, some of the coating will not reach the bearing parts and will fall onto the surface of the workbench. This requires workers to clean it up afterward. Once the coating material dries, it is not easy to clean, and the cleaning process is troublesome and time-consuming, which affects the use of the spraying device. Utility Model Content

This facilitates subsequent cleaning of the paint by the staff and allows the collecting plate 5 to be replaced, reducing downtime and improving the efficiency of the device. This, in turn, increases the device's processing efficiency for bearings.
[0027] Furthermore, the mounting plate 4 has a mounting groove 11 inside, and a motor 12 is fixedly installed inside the mounting groove 11.
