During the processing of valve bodies, the valve bodies need to be welded and fixed to the matching pipelines. Due to the special shape of the valve bodies, it is difficult to position and fix them well with traditional fixtures. The applicability is poor, manual assistance is required for fixation, which is difficult to control, unreliable, and difficult to ensure welding quality. Summary of the invention

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

The clamp has a novel structure, convenient valve body positioning, reliable clamping, and strong practicality.

[0006] Furthermore, a limiting portion is provided on the valve body positioning seat, and a limiting groove corresponding to the valve body port is provided on the limiting portion, which can limit the lateral free shaking of the valve body, thereby improving the stability of the valve body and improving the clamping effect.

[0007] Furthermore, the support portion is provided with an arc section corresponding to the valve body shell, which increases the contact area between the support portion and the valve body shell, improves the supporting effect of the support portion on the valve body shell, and thus improves the stability of the clamping.

[0008] Furthermore, a turntable is provided on both sides of the workbench, which is used to connect with the rotating shaft. Under the drive of a driving device such as a motor, the turntable is driven to rotate through the rotating shaft, and then the workbench is driven to rotate, thereby changing the contact position between the welding head and the valve body, which is beneficial to improving the welding efficiency.

[0009] Furthermore, the workbench is provided with a fixing part, which is fixedly connected to the turntable by bolts, and the fixing is reliable. The workbench and the turntable are detachable, and can be installed and used at any time, which is flexible and convenient.

[0010] Furthermore, an avoidance groove is provided on the pressure rod, and the avoidance groove is used to avoid the pipeline connected to the valve body, which will not affect the welding of the valve body and the pipeline. The structure is compact and the applicability is improved.

[0011] Furthermore, the driving mechanism adopts a stroke cylinder, which has the advantages of simple structure, light weight, easy installation and maintenance, easy adjustment, and strong adaptability.

[0012] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0013] When installing the valve body, embed the valve body interface into the positioning hole of the valve body, and embed the valve body port into the limiting groove of the limiting part to realize the rapid positioning of the valve body on the valve body positioning seat, and then start the stroke cylinder, the piston rod of the stroke cylinder extends upward, driving the tail end of the pressure rod to rotate upward, and the front end of the pressure rod rotates downward and presses against the valve body shell. The valve body is pressed on the valve body positioning seat by two symmetrically distributed pressure rods. The valve body positioning seat limits the lateral movement of the valve body, and the limiting part limits the lateral free shaking of the valve body. The valve body cannot move freely, has high stability, and is reliably clamped, which prevents displacement during welding and affects the welding quality. BRIEF DESCRIPTION OF THE DRAWINGS
