Description

Technical Field

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. When producing and processing valves, they need to be clamped and fixed with fixtures.

[0003] After searching, the existing announcement number CN211760996U is a kind of positioning tool for valve manufacturing, including a slide rail and a clamp, the slide rail is movably connected with a slider, the number of sliders is two, the bottom ends of the two sliders are fixedly installed with a sleeve, the number of sleeves is two, the internal movability of the two sleeves is connected with a screw rod, the right end of the screw rod is provided with a motor, and the output shaft of the motor is fixedly connected to the right end of the screw rod. By providing a screw rod and connecting the screw rod with the motor, when the motor is turned on, the screw rod can rotate accordingly. At the same time, because the threads on the left and right ends of the screw rod are in opposite directions, the sleeves sleeved on the outer surface of the screw rod move away or closer relatively, thereby driving the clamp to clamp the valve. The motor can always provide power and the clamp will not loosen;

[0004] In the current existing technology, common valves have a columnar structure on the outside. When clamping, they are mostly clamped and fixed on the outer surface by a clamp, which has poor stability and easily causes damage to the clamping position of the valve outer surface. Therefore, it is necessary to design a tooling fixture for valve manufacturing to solve the above problems. Utility Model Content

[0007] A column is vertically welded on the surface of the support frame, and a support tube is fixedly connected to the top of the column. Guide holes are equidistantly opened on the surface of the support tube. A guide rod is slidably inserted into the guide hole of the support tube, a positioning ball head is fixedly connected to the top of the guide rod, and a follower seat is fixedly connected to the bottom end of the guide rod, and a return spring is sleeved on the outside of the guide rod.

[0015] 1. The support frame is installed and fixed through a locking member. The columnar valve is held and sleeved outside the support cylinder. By starting the electric push rod through an external control device, the conical seat moves smoothly relative to the support cylinder. Under the thrust of the conical seat, the driven seat drives the guide rod to slide relative to the support cylinder until the positioning ball head at the end face of the support cylinder fits on the inner wall of the pipeline of the valve.
