Abstract

A mechanism of vertical lathe for machining the curved surface on the top of piston is composed of vertical tool carrier, copying plate for said curved surface, linkage plate, power cylinder on said linkage plate, slide plate sliding up and down for installing tool carrier on it, and fulcrum with curved arm, lateral branch arm and lower branch arm.

Description

technical field [0001] The invention belongs to machining tooling, in particular to a device for turning and repairing the curved top surface of a piston on a vertical lathe. Background technique [0002] For cargo ships traveling at sea, the diameter of the piston of the diesel engine is generally about 0.4-1 meter, and the top of the piston is mostly a concave surface. When the diesel engine ignites and explodes, the concave surface of the top of the piston will withstand a high temperature of thousands of degrees. After about one year of use, serious erosion points will appear, making the excessively smooth concave surface uneven, affecting the normal operation of the diesel engine. The purchase of a piston with a diameter of 1 meter for the above-mentioned diesel engine usually costs about 100,000 yuan. Therefore, after the top of the piston is corroded, it is generally used after repair. The general repair shop does not have the equipment to process the above-mentioned...
