Fixing fixture for welding repair of valve body cracks

Abstract

The invention relates to the technical field of valve body repair fixing fixtures, in particular to a valve body crack welding repair fixing fixture, including a support frame, the support frame has an L-shaped structure, a rotating motor is fixedly installed on the support frame, and the output end of the rotating motor is fixed. A connecting frame with a concave structure is installed, and spring pull rods are symmetrically fixed in the connecting frame. The telescopic ends of the two spring pull rods pass through the connecting frame and are fixedly installed with a connecting block. The side of the two connecting blocks close to each other is rotated and installed with a No. 1 cylinder. ; The efficiency of the existing valve body crack treatment method is relatively low and the labor cost is high, and manual support cannot guarantee the stability of the valve body; the present invention clamps and fixes the cracked valve body quickly and The valve body can be adjusted from multiple angles according to the position of the crack, which solves the problem of low repair efficiency in existing repair methods and reduces labor costs.

Description

technical field [0001] The invention relates to the technical field of a valve body repair fixing fixture, in particular to a valve body crack welding repair fixing fixture. Background technique [0002] The valve body is a major part of the pipeline. The valve body adopts different mechanical manufacturing methods according to its applicable pressure level, such as casting and forging. [0003] During the use of the valve body, the valve body often has cracks due to factors such as external force impact or excessive internal pressure. These cracks will affect the strength of the valve body and bring hidden dangers to the use of the valve, so the valve body has cracks. After that, it cannot continue to be used, and directly returning the cracked valve body to the furnace for rebuilding will directly increase the use cost of the valve body and is not conducive to environmental protection. Therefore, most of the existing valve body crack treatment methods are welded Solder is...

Problems solved by technology

[0003] During the use of the valve body, the valve body often has cracks due to factors such as external force impact or excessive internal pressure. These cracks will affect the strength of the valve body and bring hidden dangers to the use of the valve, so the valve body has cracks. After that, it cannot continue to be used, and directly returning the cracked valve body to the furnace for rebuilding will directly increase the use cost of the valve body and is not conducive to environmental protection. Therefore, most of the existing valve body crack treatment methods are welded Solder is filled into the gaps of the cracks to repair the cracks. At present, most of the cracks on the valve body are welded and repaired by manually supporting the valve body to keep the cracks on the valve body in a horizontal state. Therefore, two operators are often required to cooperate with the operation. The efficiency of repairing the cracks on the valve body in this way is relatively low and the labor cost is high, and manual support cannot guarantee the stability of the valve body. It is easy to cause deviation when welding and repairing cracks on the valve body, which brings inconvenience to the welding repair of cracks on the valve body
