A grinding device for a valve plate

Abstract

The invention discloses a valve plate grinding device. The valve plate grinding device comprises a rack. The rack comprises two supporting rods arranged vertically. A supporting plate is transverselyarranged between the two supporting rods. Bearings are symmetrically arranged on the sidewalls of the two supporting rods. Rotary rods arranged transversely are inserted in the bearings. The two rotary rods are connected with a valve plate through a fixing device. The rotary rods are of a hollow structure. The fixing device comprises a loop bar arranged transversely. A moving bar arranged transversely is arranged on one side of the loop bar. The other side of the loop bar is provided with a thread cavity. A threaded rod arranged transversely is in threaded connection with the interior of the thread cavity. The valve plate grinding device is fast and convenient to operate in the process of mounting and fixing the valve plate and firm in fixation, can conduct grinding on the other side of the valve plate without dismantling the valve plate and can also be used for conducting grinding on an uneven surface of the valve plate, the valve plate can be ground smooth, and the grinding efficiency is high.

Description

technical field The invention relates to the technical field of machining, in particular to a grinding device for a valve plate. Background technique At present, the surface of the valve body needs to be polished after the valve plate is manufactured to remove the burrs on the surface of the valve plate. In the prior art, the valve plate is mainly manually held on the grinding wheel for grinding. A large amount of manpower is required, and at the same time, the hand-held valve plate will not be stable enough, so that the surface of the polished valve plate is still not smooth enough to meet the qualified standard, and the grinding efficiency is relatively poor, which is not conducive to the mass production of the valve plate. For this reason, we propose a kind of grinding device of valve plate to solve the above problems. Contents of the invention The object of the present invention is to propose a grinding device for a valve plate in order to solve the problems existing...
