Clamp for turning end face of flange of flange gate valve body

Abstract

The invention relates to a clamp for turning the end face of a flange of a flange gate valve body, which is characterized in comprising a right-angle bent plate, an elastic locating supporting component which is arranged on a horizontal plate of the right-angle bent plate for putting the valve body, and a pneumatic pressure head component which is arranged on a vertical plate of the right-angle bent plate which is connected with a main shaft for downwards pressing the valve body. The elastic locating supporting component consists of a valve body support block, a clamping plate, a spring sleeve, a spring, a screw bolt and an adjusting screw nut, wherein the screw bolt is penetrated through a through hole of the screw bolt of the valve body support block and the spring, is penetrated out of a through hole of the bottom of the spring sleeve, and is fixed by the adjusting screw nut; and the pneumatic pressure head component consists of an air cylinder, a bearing connector, a connecting rod, a bending pull arm, a press head bracket and a press head, wherein one square head end of the bending pull arm is inserted into a square hole of the press head, the other end thereof is articulated with the connecting rod and is connected with a piston rod, and the top end of the bent angle of the bending pull arm is articulated with the press head bracket. The clamp has the advantages of rapidly and exactly locating the end face of the flange of the valve body, guaranteeing the marching quality, and improving the production efficiency.

Description

technical field [0001] The invention relates to a fixture for valve processing, in particular to a fixture for turning the flange end face of a flange gate valve body. Background technique [0002] Flange gate valves are widely used in many fields such as water supply engineering, sewage treatment engineering and chemical industry in urban construction as fully open and fully closed valves in pipelines. In the manufacturing process of the flanged gate valve body, it is necessary to turn the end face of the double flange to ensure that the two ends are parallel to each other and perpendicular to the axis of the valve body. The current method is manual operation, and the three-jaw chuck is used for calibration and positioning. It needs two operations, which is time-consuming, laborious, slow and has large errors, and the production efficiency is low. Contents of the invention [0003] The main purpose of the present invention is to solve the above problems, to provide a fix...
