Valve machining tool

Abstract

The invention discloses a valve machining tool which comprises a worktable and a clamping device. The clamping device is arranged at the top end of the worktable, an inner cavity of the clamping device is formed in an arc-shaped groove, a stopper is fixedly arranged on one inner side of the arc-shaped groove, containing grooves are formed in two sides of the inner wall of the arc-shaped groove, fastening rings are arranged in the containing grooves and movably connected with the containing grooves, a tightly locked screw cap is arranged on one side of the top of the clamping device, a screw isarranged at one end of the tightly locked screw cap, and one end of the screw penetrates one side wall of the clamping device. According to the valve machining tool, the clamping device is modularlydisassembled, the clamping device is only replaced when being damaged, the service life of the valve machining tool is prolonged, and different clamping devices can be replaced according to differentvalve machining shapes, so that the reuse rate of the of the whole valve machining tool is greatly increased. The valve machining tool is simple in structure, convenient to operate, safe to use and high in valve positioning efficiency.

Description

technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to a valve processing tooling. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that allows the medium (liquid, gas, powder) in the piping and equipment to flow or stop and can control its flow. The processing accuracy of the valve directly affects the sealing performance of the entire pipeline. At present, most valves have horizontal flange surfaces at both ends, which are convenient for processing and positioning; with the demand of the market, there have been valve bodies with one end flange as a horizontal surface and the other end flange as an inclined surface, which cannot be achieved by using conventional tooling. Clamping and positioning are not convenient for processing horizontal flange surfaces, especially for large valve bodies, which are supported by conventional to...

Problems solved by technology

At present, most valves have horizontal flange surfaces at both ends, which are convenient for processing and positioning; with the demand of the market, there have been valve bodies with one end flange as a horizontal surface and the other end flange as an inclined surface, which cannot be achieved by using conventional tooling. Clamping and positioning, it is not convenient to process the horizontal flange surface, especially for large valve bodies, it is supported by conventional tooling, and the structure is not stable enough
