Abstract

The invention relates to a crankshaft thrust surface polishing device which comprises a longitudinal shifting mechanism, a transverse feeding strainer mechanism and a tape mechanism, wherein the transverse feeding strainer mechanism comprises a gas cylinder, a piston rod, a sliding supporting, a splint, a pressure rod, a taper-shaped expansion rod and an expansion block, etc. The sliding supporting moves along a guide lever arranged on the seat transversely and horizontally. The invention pushes the sliding supporting via a gas cylinder piston rod and simultaneously drives a pressure rod to press the taper-shaped expansion rod tightly to make the expansion block expand and make a sand belt cling to bilateral thrust faces. The tape mechanism comprises a sand belt, a sand belt drive wheel, a sand belt driven wheel and a ratchet wheel, wherein the sand belt drive wheel drives the ratchet wheel and tapes. The sand belt shifts from the sand belt driven wheel to the sand belt drive wheel and moves a preconcerted distance. The ratchet wheel locates via a steel ball localizer. The invention has simple operation, greatly reduced working intensity of workers, high production efficiency, safe and reliable performance, high processing smooth finish and is an ideal crankshaft thrust face buffing device.

Description

technical field [0001] The invention relates to a polishing device, in particular to a crankshaft thrust surface polishing device. Background technique [0002] We know that the crankshaft is one of the important machine parts, its structure and stress are complex, the workload is heavy, and the requirements for internal metallurgical quality, casting quality and forming precision are very high. The surface roughness of the thrust surface of the crankshaft of the automobile engine is high, and it must reach Ra≤0.4 according to the performance technical requirements. Usually, the surface roughness can only reach Ra≥0.63 after finishing. To effectively solve this problem, it must be polished. The existing crankshaft thrust surface polishing device generally adopts a special crankshaft thrust surface polishing machine, which has complex structure, high price, low work efficiency and inconvenient use. Wherein the tape take-up mechanism utilizes gear shifting to drive to reali...
