Embodiment Construction

[0020] Such as figure 1 As shown, a precision three-way valve air tightness testing equipment, the equipment includes a frame 1, jig tooling 2, jig moving positioning device 3, lower switch valve device 4 and detection device 5. The jig tooling 2 is installed on the jig moving positioning device 3. The jig tooling 2 includes a jig mounting plate 201 and four jig mechanisms 20 thereon for installing three-way valves. A plurality of jig mechanisms 20 can reduce the The number of loading and unloading of the three-way valve improves the efficiency of detection. The jig moving and positioning device 3 is arranged on the frame 1 , and the jig moving and positioning device 3 is used for moving and positioning the jig tooling 2 . The lower switching valve device 4 includes a vertical movement mechanism 41 , a clamping mechanism 42 and a valve switching mechanism 43 . An up and down movement mechanism 41 is provided in the frame 1 . The clamping mechanism 42 is arranged on the up a...

Abstract

The invention relates to the field of valve switches. A lower switch valve device for precision three-way valve air tightness detection includes an up and down movement mechanism, a clamping mechanism and a valve switch mechanism; the clamping mechanism includes a mounting box, a rotating shaft, a chuck, a coupling and a clamping mechanism Cylinder; the rotating shaft is vertically arranged inside the installation box, and the outer casing of the rotating shaft is covered with a tapered outer casing, and the upper part of the outer casing has a clamping groove for the collet; the upper part of the rotating shaft is slidably installed with a collet, and The chuck is located in the housing, and the shape of the top of the chuck corresponds to the clamping groove; the lower part of the rotating shaft is connected to the coupling; the lower part of the coupling is equipped with a clamping cylinder, and the valve switch mechanism is installed on the upper part of the clamping mechanism. The switch mechanism is used to rotate the clamping mechanism to open or close the valve. The technical effect of the present invention is that the clamping cylinder pulls down the rotating shaft to move the chuck down, tightens the upper part of the chuck through the clamping groove to clamp the three-way valve, and facilitates the opening and closing of the subsequent valve.
