Polishing machine for automobile engine crankshaft

Abstract

The invention relates to the technical field of crankshaft polishing, in particular to an automobile engine crankshaft polishing machine which comprises a main box body, a polishing cavity is formed in the main box body, a telescopic clamping column is arranged on the left wall in the polishing cavity, a clamping cavity is formed in the telescopic clamping column, and a clamping table is fixedly arranged on the right end face of the telescopic clamping column. Displacement grooves which are provided with rightward openings and are evenly distributed are formed in the right side of the telescopic clamping column, fixing rods are fixedly arranged on the side walls, away from the clamping cavity, of the displacement grooves, telescopic springs capable of stretching out and drawing back are arranged on the outer circle faces of the fixing rods, and guiding sliding rails which are symmetrical left and right are fixedly arranged on the lower wall of the front side of the polishing cavity. The placing plate is fixedly arranged in the fixing shell, the friction shaft is rotationally arranged in the placing plate, the friction cavity is formed in the friction shaft, the contact shell is fixedly arranged on the side, away from the circle center of the fixing shell, of the friction cavity, the friction block makes contact with the crankshaft, rotating polishing is driven through rotation of the motor, efficiency is improved, polishing is uniform, and deformation is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of crankshaft polishing, in particular to an automobile engine crankshaft polishing machine. Background technique [0002] The engine crankshaft is an important part in the engine, and its processing requirements are more complicated. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. Therefore, the crankshaft needs sufficient strength and rigidity. , The surface of the journal needs to be wear-resistant and other characteristics. [0003] For the prior art, crankshaft polishing often requires multiple steps, and rapid polishing cannot be completed at one time. The use of polishing machines is extremely important in production. However, the traditional process is time-consuming and labor-intensive, the manual polishing efficiency is low, the precision cannot be completely controlled, and the pheno...

Problems solved by technology

[0003] For the existing technology, crankshaft polishing often requires multiple steps, and rapid polishing cannot be completed at one time. The use of polishing machines is of great significance in production.

However, the traditional process is time-consuming and labor-intensive, the efficiency of manual polishing is low, the precision cannot be completely controlled, and the phenomenon of workpiece scrapping is very easy to occur, so a device to solve the above problems is needed
