Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] like Figures 1 to 8 As shown, a solenoid valve helium inspection tool comprises: a base 1, an air supply mechanism 2, a clamping mechanism 3 and an intermediate bearing plate 5; the air supply mechanism 2 is arranged below the base 1; the clamping mechanism 3 is arranged above the base 1 and connected to the base 1 through a first support column assembly 4; the intermediate bearing plate 5 is arranged between the base 1 and the clamping mechanism 3 and connected to the base 1 through a second support column assembly 6; Among them, an air intake shaft 101 is provided at the center position of the base 1, and a through hole is provided inside the air intake shaft 101. The air supply mechanism 2 includes an air pump 201 and an air supply pipeline plate 202. A valve regulator 7 is provided between the air supply pipeline plate 202 and the air pump 201. The valve regulator 7 includes a valve switch 701 and a first pressure gauge 702 and a second pressure gauge 703 arranged at the pipeline openings at both ends; one end of the valve regulator 7 is connected to the air supply pipeline plate 202, and the other end is connected to the air pump 201, and the air intake is adjusted through the valve switch 701.

[0022] The specific implementation process of the present invention is to place the solenoid valve above the middle carrier plate 5, and set a cylinder above the clamping mechanism 3. The cylinder pushes the clamping mechanism 3, and the clamping mechanism 3 moves downward through the first sliding bearing 403. The sealing shaft 301 blocks the air hole above the solenoid valve. As the cylinder continues to press downward, the second sliding bearing 603 causes the middle carrier plate 5 to drive the solenoid valve to move downward until the intake shaft 101 passes through the middle carrier plate 5 and enters the solenoid valve. After the clamping mechanism 3 and the middle carrier plate 5 are clamped and installed on the solenoid valve, turn on the air pump 201 and enter the solenoid valve through the pipeline in the air supply mechanism 2 and the intake shaft 101. When the air pressure values ​​of the first pressure gauge 702 and the second pressure gauge 703 at the left and right ends of the valve adjustment switch 701 remain stable, the pressure values ​​of the two gauges are consistent. At this time, the valve switch 701 is closed. If the indication of the second pressure gauge 703 remains unchanged, it indicates that the sealing performance of the solenoid valve is good. The present invention can adapt to the detection requirements of solenoid valves of different sizes through the setting of the clamping mechanism 3, the intermediate bearing plate 5 and the bottom plate 1, and can accurately control the gas flow and pressure in the gas supply pipeline through the setting of the valve regulator 7, thereby effectively ensuring the accuracy and reliability of the solenoid valve detection results.

[0023] In the present invention, four groups of first support column assemblies 4 are arranged and arranged at four diagonal positions of the base 1; the first support column assembly 4 includes a vertically arranged connecting shaft 401, a first spring 402 arranged between the base 1 and the clamping mechanism 3 and sleeved on the connecting shaft 401, and a first sliding bearing 403 slidably arranged on the connecting shaft 401; the first sliding bearing 403 is fixedly arranged on the clamping mechanism 3, and the first spring 402 performs contraction and extension movement with the up and down movement of the first sliding bearing 403. By adjusting the position of the first sliding bearing 403 through the sliding connection between the first sliding bearing 403 and the connecting shaft 401, the preload force of the first spring 402 can be increased or decreased as needed, thereby adjusting the clamping force of the clamping mechanism 3 on the solenoid valve.

[0024] In the present invention, a sealing shaft 301 is provided on the side of the clamping mechanism 3 facing the base 1, a sealing structure is provided on the sealing shaft 301, and the end edge of the sealing shaft 301 is rounded; a sealing groove 8 is provided around the connection between the sealing shaft 301 and the clamping mechanism 3, and a sealing ring is provided in the sealing groove 8.

[0025] The tight fit between the sealing shaft 301 and the solenoid valve can effectively prevent leakage of gas or liquid and ensure the stability of the gas environment in the intermediate carrier plate 5, thereby improving the accuracy and reliability of helium detection of the solenoid valve. The groove and rounded corner design on the sealing shaft 301 can disperse the stress and impact force generated by the clamping mechanism 3 during the clamping process to avoid structural deformation or damage.

[0026] In the present invention, the upper surface of the intermediate carrier plate 5 is provided with a mounting groove 501, and the bottom of the mounting groove 501 is provided with an air inlet hole 5011, which penetrates the intermediate carrier plate 5 and is connected to the through hole of the air inlet shaft 101 arranged on the base 1; a sealing groove 8 is arranged around the air inlet hole 5011, and positioning holes 9 are symmetrically arranged on both sides of the lower part of the intermediate carrier plate 5. The setting of the air inlet hole 5011 enables the gas to directly and efficiently enter the intermediate carrier plate 5, thereby ensuring the accuracy and stability of the gas flow during the helium detection of the solenoid valve; the air inlet hole 5011 penetrates the intermediate carrier plate 5 and is connected to the air inlet shaft 101 on the base 1, which simplifies the gas flow path, reduces the resistance and loss of the gas during the circulation process, and improves the detection efficiency; the setting of the sealing groove 8 can accommodate sealing elements such as a rubber sealing ring, effectively preventing the gas from leaking from the gap between the mounting groove 501 and the intermediate carrier plate 5, and ensuring the air tightness of the intermediate carrier plate.

[0027] As a preferred embodiment of the above embodiment, the second support column assembly 6 includes an adjustment shaft 601, a second spring 602 disposed in the positioning hole 9, and a second sliding bearing 603 disposed at the upper end of the adjustment shaft 601; the second sliding bearing 603 is slidably connected to the adjustment shaft 601, and the distance between the intermediate bearing plate 5 and the base 1 is adjusted by the second sliding bearing 603. The second spring 602, as an elastic element, can absorb and disperse the stress and impact force generated by the tooling during use, thereby protecting the intermediate bearing plate 5 and the base 1 from damage, and the height adjustment of the second sliding bearing 603 can ensure the close fit between the solenoid valve and the intake shaft 101, prevent gas or liquid leakage, and help improve the accuracy and reliability of the helium detection of the solenoid valve.

[0028] In the present invention, the upper end of the air intake shaft 101 is rounded, and a sealing groove 8 is provided around the connection between the air intake shaft 101 and the base 1; a sealing groove 8 is provided at the contact position between the air intake shaft 101 and the air supply pipeline plate 202, which can accommodate sealing elements such as rubber sealing rings to ensure a close fit between the air intake shaft 101 and the base 1 to prevent leakage of gas or liquid.

[0029] As a preferred embodiment of the above embodiment, a spring hole 102 corresponding to the positioning hole 9 is provided on the upper part of the base 1; the upper end of the second spring 602 is placed in the positioning hole 9, and the lower end of the second spring 602 is placed in the spring hole 102, so that the second spring 602 can be firmly installed between the base 1 and the intermediate bearing plate 5, providing additional support and stability for the entire tooling; the coordinated use of the spring hole 102 and the positioning hole 9 ensures that the second spring 602 can be correctly positioned and installed, providing the necessary pressure regulation and buffering functions for the intermediate bearing plate 5, and the second spring 602 can automatically detach the inspected solenoid valve from the tooling, reducing the disassembly process and improving the inspection efficiency.

[0030] In the present invention, the air supply pipeline plate 202 includes an air groove 2021 connected to the through hole of the air intake shaft 101, and a multi-way air intake passage 2022 arranged in the air groove 2021 on one side of the air pump 201; one end of the multi-way air intake passage 2022 converges to the air groove 2021; and in the preferred embodiment, the multi-way air intake passage 2022 gradually diffuses outward in the direction away from the air groove 2021, and a control valve is provided in each air intake passage 2022. The diameters of the multi-way air intake passage 2022 are different, and multiple air intake passages 2022 can be opened at the same time according to different gas flow requirements to speed up the gas supply speed in the solenoid valve, reduce the inflation waiting time, and improve the detection efficiency.

[0031] The gas to be tested of multiple air intake devices is delivered to the air tank 2021 by the air pump 201. According to the actual gas flow demand and the detection requirements, the air supply mode is adjusted by controlling the air passage 2022 of the corresponding air intake passage 2022 through the control valve. In the independent control mode, each air intake device is equipped with a separate control valve, which can control the on and off of each air passage separately; in addition, multiple sets of detection fixtures can be set on the air supply pipeline plate 202, and the multiple air intake passages 2022 correspond to each other one by one. A centralized control valve is used to realize synchronous control, so that multiple air intake devices can be supplied with gas at the same time, thereby realizing the test air supply requirements of multiple solenoid valves and improving the detection efficiency.

[0032] The multi-gas circuit setting allows different solenoid valves to be controlled individually, increasing the flexibility of operation. In addition, the multi-gas circuit system can integrate gas sources from different sources, improving the stability of gas supply and preventing gas outages and gas cuts caused by problems with a single gas source.
