Coating device

Abstract

The invention relates to a coating device. A coating device is used for coating a to-be-coated part and comprises a vacuum chamber; the at least one rotating disc is located in the vacuum chamber, the rotating disc is internally provided with a disc cavity used for containing a to-be-coated part, a disturbance rod is arranged in the disc cavity, and a gap is formed between the disturbance rod and the bottom wall of the disc cavity; and the transmission mechanism is positioned in the vacuum chamber and is used for driving the turntable to rotate around the central axis of the turntable relative to the disturbance rod, so that the disturbance rod changes the rolling direction of the to-be-coated part in the disc cavity. When the rotating disc rotates relative to the disturbance rod, friction cannot be generated between the disturbance rod and the bottom wall of the disc cavity due to the existence of the gap, so that a rubbing object generated due to friction between the disturbance rod and the bottom wall of the disc cavity can be prevented from being adhered to the surface of the to-be-coated part, and the film layer uniformity of the surface of the to-be-coated part can be ensured as much as possible.

Description

technical field [0001] The present invention relates to the technical field of coating devices, in particular to coating devices. Background technique [0002] Bearings are widely used in all walks of life, and their performance and quality also directly affect the performance and life of the corresponding complete machine products. Therefore, the demand for bearings has been developing in the direction of high performance and long life, so that the balls and grooves in the bearings are affected. The lubricity and wear resistance of the road put forward higher requirements. Under such development needs, high-precision ball and channel coatings came into being. [0003] In the field of medical device applications, the CT tube, the core component of the CT machine, is mainly used to generate X-rays, so as to irradiate various parts of the human body / animal to check the pathological conditions of each part. When the CT machine is working, the CT tube is in a high temperature,...

AI Technical Summary

Problems solved by technology

[0005] Based on this, it is necessary to provide a coating device that can improve the uniformity of the film on the surface of the ball in view of the technical problem that the ball is coated with the current coating device and the uniformity of the film on the surface of the ball is poor.
