A high-pressure-resistant eccentric cover for machine tools and its forming process

Abstract

The invention discloses a high-pressure-resistant eccentric cover for machine tools and its forming process, which includes an upper eccentric sleeve, a lower eccentric sleeve, an eccentric runner and a movable installation opening. The eccentric rotation of the parts in between, wherein the tooth grooves on the central base wheel in the eccentric runner and the inner tooth grooves in the inner gear ring are meshed with each other, a buffer groove is set at the rear side of the inner gear ring, and filled Two sets of buffer washers, during the long-term eccentric rotation of the eccentric runner, the buffer washers provide buffer force to the inner gear ring and the center base wheel, thereby reducing the friction loss during the rotation of the center base wheel, and the external Under the action of high-strength impact force, it can effectively protect the center base wheel and the inner gear ring, avoid problems such as cracking or breaking, reasonably reduce the friction loss in the eccentric cover parts, and improve its impact resistance, effectively improving the eccentric cover. service life.

Description

technical field [0001] The invention relates to the technical field of machine tool accessories, in particular to a high-pressure-resistant eccentric cover for machine tools and its forming process. Background technique [0002] Machine tools refer to machines that manufacture machines, also known as machine tools or machine tools. They are customarily referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing. , as well as casting, forging, welding, stamping, extrusion, etc., but all parts with higher precision requirements and finer surface roughness requirements generally need to be final processed on machine tools by cutting methods.

[0002] Machine tools refer to machines that manufacture machines, also known as machine tools or machine tools. They are customarily referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing. , as well as casting, forging, welding, stamping, extrusion, etc., but all parts with higher precision requirements and finer surface roughness requirements generally need to be final processed on machine tools by cutting methods. Machine tools play an important role in the modernization of the national economy The eccentric cover plays an important role in the construction of the machine tool. The eccentric cover is an important part of the transfer part of the machine tool. Through the interaction of a group of parts with different centers, the circular movement of the connection part on the same horizontal plane can be realized, so as to facilitate the alignment of the machine tool. Parts are processed at different angles in various directions. The pressure bearing strength of the eccentric cover in the prior art is weak, and the wear degree of the eccentric part is relatively serious due to long-term activities, and the risk of cracking or even breaking of the eccentric cover is prone to occur, thus It affects the processing quality of the parts being processed, and after the eccentric cover has cracks, the processing accuracy of the parts is greatly reduced
