Abstract

The invention relates to a precise automobile part remanufacturing pretreatment method. Precise automobile part remanufacturing pretreatment equipment is used in the method and comprises a base and a cleaning device, and the cleaning device is arranged on the upper surface of the base. The method can solve the following problems that the used cleaning equipment only drives an engine crankshaft to rotate, so that a cleaning brush in the cleaning equipment forms a brushing action on the engine crankshaft, the cleaning efficiency of the engine crankshaft is reduced through unilateral rotation, in the process of brushing the engine crankshaft by the cleaning brush in the cleaning equipment, greasy dirt on the engine crankshaft can be brushed down and attached to the cleaning brush at the same time, the existing cleaning equipment does not remove the greasy dirt attached to the cleaning brush in time, the engine crankshaft is difficult to clean, the cleaning time of the crankshaft is prolonged, and the working efficiency is reduced.

Description

technical field

[0001] The invention relates to the field of auto parts manufacturing, in particular to a remanufacturing pretreatment method for precision auto parts. Background technique

[0002] The crankshaft is the most important part of 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. The crankshaft is subjected to the centrifugal force of the rotating mass, the periodically changing gas inertial force and The combined effect of reciprocating inertial force makes the crank bearing subject to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work uniformly, and have good balance; when maintaining and repairing the engine, it is necessary to The crankshaft is disassembled and inspected to determine whether the crankshaft can be used again. If it cann...
