Polishing machine used for machining automobile crankshaft

Abstract

The invention discloses a polishing machine used for machining an automobile crankshaft and relates to the field of machining of automobile parts. The polishing machine comprises a box. A first motor is fixedly connected to the bottom of the inner wall of the box. A first belt wheel is fixedly connected to one end of an output shaft of the first motor. The surface of the first belt wheel is in transmission connection with a feeding device through a first belt. A second motor is fixedly connected to the bottom of the inner wall of the box. A first lead screw is fixedly connected to the output shaft end of the second motor through a first coupling. A sliding table is slidably connected to the bottom of the inner wall of the box and located on the right side of a third vertical plate. A supporting rod is fixedly connected between the two sides of the inner wall of the sliding table. The first lead screw is connected with the supporting rod in an engaged mode. A third motor is fixedly connected to the top of the sliding table. A lifting device is fixedly connected to the output end of the third motor. By adoption of the polishing machine for machining the automobile crankshaft, the problems that traditional crankshaft polishing equipment is complex in structure, and manual clamping is needed are solved, cost is reduced, labor is saved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of automobile parts processing, in particular to a polishing machine for automobile crankshaft processing. 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 action 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. The surface of the journal needs to be wear-resistant, work uniformly, and have good balance. In crankshaft processing, polishing is an important one. The link determines the service life of the crankshaft. The existing polishing device has a complex structure, ...
