Problems solved by technology

[0003] The following problems are often encountered in the process of crankshaft manufacturing and processing: 1. The crankshaft needs to be ground during the production process, but the contact area between the crankshaft and the ground execution end is too small, so that the connecting journal cannot always be in contact with the ground end during the rotation process. 2. When the crankshaft is polished by the belt, the belt wears quickly, and it is difficult to select the critical point of the belt to replace the belt, so that the belt with high wear degree can grind the crankshaft not strong enough

Abstract

The invention relates to a manufacturing process of an engine camshaft, which uses a surface grinding device, the surface grinding device includes a base, a fixing unit and a grinding unit, the upper left side of the base is provided with a fixing unit, and the grinding unit is installed on The right side of the upper end of the base; the invention increases the contact area and time between the connecting journal and the grinding belt by increasing the contact area between the engine camshaft and the grinding execution end, so that the connecting journal cannot always be in contact with the grinding end during the rotation process , so that the problem of incomplete grinding of the connecting journal is solved; the present invention keeps the wear degree of the grinding end above a certain value by continuously replacing the grinding belt at the execution end, and solves the problem of poor grinding effect.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine camshaft manufacturing process. Background technique [0002] The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine to work. The crankshaft is subjected to the combined action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance. Usually we refer to the engine speed as the crankshaft speed. [0003] The following problems are often encountered in the process of crankshaft manufacturing and proce...
