Eccentric shaft machining tool and machining method

Abstract

The invention disclose an eccentric shaft machining tool and machining method. The tool comprises a left eccentric sleeve, a right eccentric sleeve, a left nut and a right nut, blind holes are formed in the center of the left eccentric sleeve and the center of the right eccentric sleeve, a left threaded sleeve integrally connected with the left eccentric sleeve is arranged at an opening of the blind hole of the left eccentric sleeve, a first eccentric hole and a second eccentric hole are formed in the other end of the left eccentric sleeve, a right threaded sleeve integrally connected with the right eccentric sleeve is arranged at a blind hole opening of the right eccentric sleeve, a third eccentric hole and a fourth eccentric hole are formed in the other end of the right eccentric sleeve, and three expansion joints are evenly distributed on the circumference of each of the left threaded sleeve and the right threaded sleeve. The tool is simple in structure and convenient to operate, repeated benchmark correction is not needed in the continuous machining process, assembly line automatic operation can be achieved, eccentric shafts can be produced on a large scale through universal simple equipment, limitation of special equipment is overcome, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an eccentric shaft processing tool and a processing method, belonging to the technical field of mechanical processing. Background technique [0002] In mechanical transmission, rotary motion is changed to reciprocating motion or reciprocating motion is changed to rotary motion, which is mostly realized by eccentric shaft parts. Eccentric shafts are used in many fields, such as automotive engines, aero engines, and gear transmission with few tooth differences. device etc. [0003] With the development of production and technological innovation, in many high-precision transmission devices, the demand for high-precision eccentric shafts is increasing, and higher and higher requirements are put forward for the accuracy and eccentric structure of eccentric shafts, such as single eccentric, double eccentric Eccentricity, multi-eccentricity, symmetrical eccentricity, asymmetrical eccentricity, etc. The eccentric circle diameter accu...

AI Technical Summary

Problems solved by technology

[0004] At present, the processing of the eccentric outer circle of the high-precision eccentric shaft must be completed by special equipment (such as crankshaft grinder, coordinate grinder, etc.), the equipment purchase cost is high, the production efficiency is low, and the manufacturing cost of a single part is high, so it is difficult to achieve mass production and improve market competition. force
