Valve clack sphere grinding machine of double eccentric semi-ball valve

Abstract

The invention discloses a valve clack sphere grinding machine of a double eccentric semi-ball valve. A frame (1), a motor (2), a loading workpiece rotating main shaft (4) and a tool (5) are arranged on an engine base (3), wherein the frame is arranged on the upper part of the engine base and provided with an angle adjustment frame (6) with adjustable angles; a rotating auxiliary shaft (7) is fixedly connected to the angle adjustment shaft; a grinder clamping mechanism (8) is arranged on the rotating auxiliary shaft, and a semispherical grinder body (9) is fixedly connected to the grinder clamping mechanism; the lower part of the engine base corresponding to the rotating auxiliary shaft (7) is provided with the loading workpiece rotating main shaft which simultaneously rotates with the rotating auxiliary shaft and has opposite direction to the rotating auxiliary shaft, and the tool used for fixing a semi-sphere is arranged on the loading workpiece rotating main shaft; and the upper end of the tool is a semispherical positioning disk eccentrically arranged on the loading workpiece rotating main shaft. Through the adjustment of the angle adjustment frame, the grinder rotates on a semi-ball valve clack at a uniform speed so as to form mutually crossed reticular tracks and achieve an ideal ball grinding surface.

Description

technical field [0001] The invention relates to a hemispherical grinder, in particular to a spherical grinder for double eccentric hemispherical valve discs. technical background [0002] The existing spherical surface grinding machine for hemispherical valves mainly uses a grinding tool (grinding pot) plus abrasives to rotate the valve disc ball in a semi-suspended state in the pot, and grinds by manual multi-directional swings, which is not only labor-intensive, but also low in production efficiency. Moreover, the artificial swing is not standardized, the grinding efficiency is low, and the spherical crown cannot reach the ideal spherical state, which directly affects the product quality. Contents of the invention [0003] The object of the present invention is to propose a double eccentric hemispherical valve disc spherical grinder aiming at the deficiencies of the above-mentioned prior art. The grinding tool rotates at a constant speed on the hemispherical valve disc ...

Problems solved by technology

[0002] The existing spherical surface grinding machine for hemispherical valves mainly uses a grinding tool (grinding pot) and an abrasive to rotate the disc sphere to be placed in a semi-suspension state in the pot, and it is ground by manual multi-directional swings, which not only has high labor intensity but also low production efficiency. Moreover, the artificial swing is not standardized, the grinding efficiency is low, and the ground spherical crown cannot reach the ideal spherical state, which directly affects the product quality
