Polishing machine for machining engine connecting rod

Abstract

The utility model relates to a polishing machine for machining an engine connecting rod, which comprises a working table, a door-shaped frame is fixedly arranged at the top of the working table, a translation mechanism is arranged in the door-shaped frame, and an adjusting mechanism is arranged at the top of the working table; and the translation mechanism comprises a driving motor, the driving motor is fixedly installed on the left side of the door-shaped frame, and an output shaft of the driving motor is fixedly connected with a lead screw. According to the polishing machine for machining the engine connecting rod, by arranging the adjusting mechanism and the translation mechanism, after one end of the connecting rod is polished by the polishing head, the supporting plate is driven by the electric guide rail to move forwards or backwards, and then the lead screw can be driven by the driving motor to rotate, so that the moving block drives the polishing head to translate to the other end of the connecting rod; and then the electric guide rail drives the supporting plate to move back to the original position, the other end of the connecting rod can be continuously ground, the direction of the connecting rod does not need to be adjusted, use is convenient, and the grinding efficiency is improved.
