Abstract

The invention discloses a vacuum coating device for an inner surface of an elongated tubular part. The device comprises a support base, a support table and a laser discharge tube of which two ends arerespectively provided with a first rubber plug and a second rubber plug through sealing resin and the device also comprises a compound plating head for evaporation coating, a gas suction system for monitoring and maintaining a vacuum degree, a pressure regulating system for communicating the compound plating head and releasing large current and a transmission system for achieving uniform movementof the compound plating head. The transmission system comprises a stepping motor, a motor controller, a synchronous toothed opening belt, two synchronous toothed wheels, an electrode tube clamping slider, a timing belt pressure plate, an aluminum profile rail, a rolling ring and an electrode tube. Through use of the moving discharge electrode and the compound plating head preventing touch damage,the consistency of the discharge intensity at any positions and distances between the positions and the tube wall is ensured in the vacuum plating process so that uniform coating on the inner wall ofthe elongated tube is realized. The vacuum coating device is worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of electroplating equipment, more specifically, it relates to a vacuum coating device for the inner surface of a slender tubular part. Background technique [0002] Laser tubes are widely used in the laser cutting industry as industrial consumables. For laser tubes of the same power, price and service life are the main factors affecting sales, and the key to determining service life is the life of the laser discharge tube. The laser discharge tube has early failure due to inner surface corrosion and oxidation, and the ordinary treatment process is difficult to meet the requirements of inner surface strengthening. Therefore, the coating process is generally used in China, and the conventional electroplating method has problems such as electrolyte pollution and easy peeling of the film. , Gradually adopt the vacuum coating process to process the inner surface of the laser discharge tube. [0003] Vacuum coat...
