The invention relates to a dynamic sealing device capable of doing reciprocating motion at a high speed and a method. The dynamic sealing device comprises at least two control channels, at least two dynamic sealing mechanisms, a control device, a workpiece driving device, a gap adjusting mechanism, a motor and a transmission gear. The two sides of a vacuum chamber are correspondingly connected with the control channels, and the two dynamic sealing mechanisms are correspondingly connected with the two sides of the vacuum chamber through the control channels. Each dynamic sealing mechanism comprises a sealing plate and two rubber rollers with grooves. Every two rubber rollers are vertically arranged. The outer circumferential surfaces of every two roller bodies are in tight contact with each other. The sealing plates are located on the rear sides of the rubber rollers. Flanges in tight fit with the grooves are arranged at the two ends of the surface of the front side of each sealing plate. A workpiece hole is formed in each sealing plate. A gap channel is arranged on the front side of each sealing plate. Tapered plates are arranged on the left side and the right side of each gap channel. The dynamic sealing device is suitable for high-speed reciprocating motion of special-shaped workpieces with the high-roughness outer surfaces, and the airtightness is high.
Description
technical field [0001] The invention belongs to the technical field of vacuum sealing, and relates to a vacuum dynamic sealing system for high-speed reciprocating motion of circular, plate-shaped, elliptical and other special-shaped workpieces with high-roughness outer surfaces, in particular to a high-speed reciprocating motion Dynamic sealing device and method. Background technique [0002] The traditional sealing technology is used for the reciprocating motion sealing of workpieces with rough surfaces, which has high wear, high energy consumption, short life, and poor sealing effect. The vacuum dynamic sealing device of the present invention for the reciprocating motion of workpieces with rough surfaces has low wear and long life, and is suitable for high-speed reciprocating motions of circular, plate-shaped, elliptical and other special-shaped workpieces with high-roughness outer surfaces, and has strong sealing performance .
