End-face grinding device for air intake and exhaust valves of internal combustion engines

Abstract

An end-face grinding device for air intake and exhaust valves of internal combustion engines structurally comprises a roller, an under carriage, a motor, a controller, a speed governor, a protective cover, a limit rod and a grinding wheel. The under carriage is concave, and has hard outer surface and hollow inside, and the left and right sides of the under carriage are the same and parallel to each other; the speed governor is arranged on the controller. The end-face grinding device has the advantages that, with the arrangement of the speed governor, rotation speed is changed through a variable-speed chip by turning a speed-adjusting knob and is subjected to parallel process through a processing unit, while an actuator is used for controlling operation of a controlled object, so that end-face grinding speed can be increased or decreased according to states of products, precision of the grinding work can be improved, and the work efficiency is improved as the end-face grinding can be completed with single feeding; besides, by application of the end-face grinding device, surface quality of the workpieces under end grinding can be improved, end-face grinding efficiency can be improved, labor intensity of workers can be reduced, and the purpose of guaranteeing both quality and productivity of finish products can be achieved.

Description

technical field [0001] The invention relates to an end grinding device for an intake and exhaust valve of an internal combustion engine, which belongs to the technical field of auto parts production.
