Description

Technical Field

[0001] The utility model relates to the technical field of distribution valves, in particular to a rapid positioning device for a distribution valve test bench. Background Art

[0002] The distribution valve is an important component in the hydraulic system, used to control flow and direction. The working principle of the distribution valve is based on the effect of hydraulic pressure. Before using the distribution valve, it is usually necessary to send it to the distribution valve test bench to test the quality of the distribution valve.

[0003] When conducting experiments on a distribution valve, the distribution valve is usually placed on a test bench, and the distribution valve is positioned by rotating the screws around it to drive the clamp to move. As a result, when conducting experiments on the distribution valve, positioning and releasing the distribution valve takes a lot of time, which affects the experimental efficiency of the distribution valve and reduces the experimental efficiency of the distribution valve.

[0004] According to the publication number: CN216504664U, a fixing device for stainless steel valve processing is provided, which includes a device body and a support block. A groove is provided at the center of the top of the device body, and a filter plate is installed in the groove. A fixing ring is fixedly installed on the outer circle of the groove at the top of the device body through multiple groups of mounting rods. Four groups of rotating screws are installed through the threads on the fixing ring. One end of the rotating screw is connected to and installed with a limit block. The backs of both ends of the limit block are connected and installed with the fixing ring through a fixing mechanism. The utility model has four groups of rotating screws installed through the threads on the fixing ring. One end of the rotating screw is connected to and installed with a limit block. The stainless steel valve is limited and fixed by the limit block. The limit block is adjusted by rotating the rotating screw, which is convenient for fixing stainless steel valves of different aperture sizes, realizing the adjustable effect of the fixing device and improving the applicability of the fixing device.

[0005] According to the fixing device introduced above, the distribution valve is positioned by rotating the screws around to drive the clamping block to move. As a result, when the distribution valve is tested, positioning and releasing it takes a lot of time, which affects the experimental efficiency of the distribution valve and reduces the experimental efficiency of the distribution valve. Therefore, we need to propose a rapid positioning device for the distribution valve test bench. Utility Model Content

After the experiment is completed, the turntable 42 is rotated counterclockwise to allow the bidirectional screw 41 to drive the moving seats 43 at both ends away from the distribution valve, so that the positioning block 8 releases the distribution valve, and then the positioning rod 106 is pulled out and moved out of the inner cavity of the first positioning hole 104 and the second positioning hole 105 to release the position of the slider 101. The distribution valve can be taken out of the experimental fixed table 1, thereby realizing rapid positioning and release of the distribution valve, reducing the impact on the experimental efficiency of the distribution valve, and improving the experimental efficiency of the distribution valve.
