Polishing device for double-hole valve seat

Abstract

The invention discloses a polishing device for a double-hole valve seat, and relates to the technical field of valve seat machining. The polishing device aims at solving the problems that an existingvalve seat is polished manually, the manual operation is low in efficiency, the labor cost is high, and the product polishing precision cannot be guaranteed. According to the scheme, the polishing device comprises a bottom plate, a clamping mechanism is arranged at the top of the bottom plate in a sliding mode, supporting plates fixedly connected with the two sides of the top of the bottom plate are movably arranged outside the clamping mechanism in a sleeving manner, a transverse plate is fixedly connected to the sides, close to each other, of the two supporting plates, a hydraulic cylinder is fixedly connected to the bottom of the transverse plate, and an output shaft of the hydraulic cylinder is fixedly connected with a speed reducer. According to the polishing device, valve seats withdifferent sizes can be conveniently fixed and polished, and large-range synchronous polishing is facilitated; and meanwhile, the position of the valve seat can be adjusted during polishing, the polishing efficiency is improved, the integration and automation degree of the whole device is high, and the labor cost of enterprises is saved.

Description

technical field [0001] The invention relates to the technical field of valve seat processing, in particular to a grinding device for a double-hole valve seat. Background technique [0002] During the production of the valve seat, the valve body needs to be polished. The existing grinding operations are generally handled by the staff with hand-held grinding equipment. However, the hand-held operation of the staff is not only inefficient, but also unable to work for a long time, which will cause wrist It is tiring, and the precision of grinding cannot be guaranteed, which leads to the inability to improve the production efficiency of the enterprise, and the labor cost is high. For this reason, we propose a grinding device for double-hole valve seats. Contents of the invention [0003] The grinding device for a double-hole valve seat proposed by the present invention solves the problem that the existing valve seat grinding relies on manual operation, and the manual operation ...
