Self-positioning bridge type grinding tool equipment for rocker arms

Abstract

The invention relates to self-positioning bridge type grinding tool equipment for rocker arms, which is characterized by comprising a flange plate (1), wherein the front end face of the flange plate (1) is connected with a fixed ring; a cover plate (5) is arranged at the upper half of the front end face of the fixed ring (2); a rotation shaft (6) penetrates into the cover plate (5), the fixed ring (2) and the flange plate (1); the rotation shaft (6) is located right above the center of the fixed ring (2); an eccentric wheel (7) which is arranged in the fixed ring (2) is arranged on the rotation shaft (6); a spring bolt (11) is arranged blow the eccentric wheel (7); a pressing plate (8) and a bearing seat (9) arranged up and down are arranged in the fixed ring (2); a cushion block (10) is arranged above the pressing plate (8); and a spring leaf (12) is arranged between the spring bolt (11) and the cushion block (10). The self-positioning bridge type grinding tool equipment for rocker arms has the advantages of being better in quality of grinding inner holes of rocker arms and higher in positioning efficiency.

Description

Technical field [0001] The invention relates to a self-positioning bridge grinding tool for a rocker arm. Background technique [0002] Due to the rapid development of modern science and technology, the machinery industry, electronics industry, aerospace industry, chemical industry, etc., especially the defense industry, require cutting-edge science and technology products to develop in the direction of high precision, high speed, high power, and miniaturization. Long-term reliable work under high temperature, high pressure, heavy load or corrosive environment. In order to meet these requirements, a large number of precision parts with new structures, new materials and complex shapes have appeared. Their mechanisms and shapes have become more and more complex, the performance of materials has become stronger and tougher, and the accuracy requirements have become higher and higher. The requirements of roughness and integrity are becoming stricter and stricter, making machine manu...

AI Technical Summary

Problems solved by technology

Foreign rocker arms are mainly manufactured by professional manufacturers, and high-precision CNC lathes and CNC grinding equipment are generally used. They are characterized by short production cycles, stable quality, long service life, and rapid development and meeting market demand. However, due to high product precision requirements, in In the rocker arm industry in relatively developed countries such as the United States, Germany, Britain, Sweden, and Japan, the above processing methods are generally used, so the manufacturing cost of foreign rocker arms is also high under the premise of high quality.

Domestic rocker arms produced by general domestic manufacturers have poor inner hole grinding quality and low positioning efficiency, which cannot satisfy customers
