Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic valve detection equipment, and in particular relates to a electromagnetic valve comprehensive detection workbench. Background Art

[0002] Existing solenoid valve detection usually uses observation method directly, because the solenoid valve is like a switch, which can realize the on-off function after the coil voltage is applied. For example, if the solenoid valve that controls the air source does not receive the air source after the voltage is applied, it means that the solenoid valve is not working, or the solenoid valve is not disconnected, and it can be judged that the solenoid valve is damaged. The above detection method requires a lot of manpower and there are detection errors, which makes it inconvenient to accurately detect and judge the on-off status of a large number of solenoid valves. In addition, if conventional ventilation detection is used, it can only determine the on-off of the solenoid valve, and cannot further detect the flow status of the internal medium.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses an online solenoid valve detection station [201110201569.0], which includes an air intake component, a fixture, a signal acquisition module and a process control module. The air intake component includes an air pressure regulation and control module and a pressure maintaining component for controlling the air intake pressure. One end of the air intake component is connected to the external air source, and the other end is connected to the air inlet of the solenoid valve under test; the signal acquisition module is used to collect the air pressure signal of the same measured point in time; the process control module judges the air tightness of the valve under test by processing the data signal collected in time by the signal acquisition module. The device uses a pressure sensor and adopts a pressure maintaining method to realize dry leak detection of the device under test. The pressure sensor is connected to the acquisition module, and the air pressure values ​​in different time periods are collected, and the software quantitatively analyzes to determine whether the device under test is leaking.

[0004] The above solution solves the problem of air tightness detection of existing solenoid valves to a certain extent, but the solution still has many shortcomings, such as the lack of means for detecting the flow state of the internal medium. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figures 1-4 As shown, a solenoid valve comprehensive testing workbench includes a main platform body 1 installed on the testing platform, and the main platform body 1 is adjusted to a specified height according to actual needs; a plurality of testing stations 2 are arranged on the upper end of the main platform body 1 for fixing the solenoid valves one by one, and the testing stations 2 are equipped with clamping components 3 to apply clamping torque to prevent loosening and dislocation. In order to realize the flow state detection of the medium inside the solenoid valve, a gas guide component 4 that can switch between series and parallel states is arranged between adjacent testing stations 2 to switch the gas flow path, and cooperates with the sensor element to detect the flow rate and pressure fluctuation state. A switching component 5 corresponding to the testing station 2 and the gas guide component 4 is arranged in the main platform body 1 to ensure the air tightness of the switching point.

[0024] Specifically, the main table body 1 adopts a modular design, which specifically includes an upper table board 11 and a lower table board 12. A support column 13 is connected between the upper table board 11 and the lower table board 12 to provide an assembly space for the solenoid valve. A support platform 14 is fixed on the lower table board 12 and the support platform 14 is isolated from the lower table board 12. The detection stations 2 are arranged at equal intervals on the support platform 14, and multiple detection stations 2 can detect multiple solenoid valves at one time. At the same time, the main table body 1 can carry a corresponding circuit detection system to detect the solenoid valve control circuit one by one.

[0025] In-depth, each detection station 2 has a detection slot 21 for the solenoid valve to be inserted, and the port shape of the detection slot 21 is adapted to the outer wall of the solenoid valve. A hollow opening 22 is left between adjacent detection stations 2 to accommodate the corresponding air guiding component 4, and a conducting opening 23 is left between the detection slot 21 and the hollow opening 22 for the air guiding component 4 to pass through and connect with the solenoid valve port.

[0026] Further, similar to a conventional fixture, the clamping component 3 includes pneumatic push rods 31 installed on both sides inside the detection slot 21. The telescopic ends of the pneumatic push rods 31 are connected with clamping blocks 32, and different clamping blocks 32 can be selected for different solenoid valves for adaptation. A clamping plate 33 that abuts against the solenoid valve is arranged at the port of the detection slot 21 for further limiting to prevent the solenoid valve from completely falling into the detection slot 21 and affecting subsequent replacement.

[0027] Even further, the air guiding component 4 adopts external air supply, including a nozzle 41 installed in the hollow opening 22. A switching component that corresponds to the detection stations 2 one by one and is connected with the nozzle 41 is installed outside the support platform 14. On the one hand, the switching component controls the on-off of the nozzle 41, and on the other hand, it adjusts the air path state of adjacent solenoid valves.

[0028] In addition, the switching component includes paired three-way valves 42. One outlet of each three-way valve 42 is connected with the nozzle 41, and the other outlet is connected with the inlet of another three-way valve 42. Stop valves 43 are respectively installed between the three-way valves 42 and the nozzle 41. In adjacent three-way valves 42, the outlet of one three-way valve 42 is connected with the inlet of the solenoid valve, and the inlet of the other three-way valve 42 is connected with the outlet of the solenoid valve.

[0029] By controlling the on-off of the stop valves 43, the parallel connection of multiple solenoid valves is realized. When there is no solenoid valve in the detection station 2, the corresponding stop valve 43 is closed so that the air guiding component 4 corresponding to the detection station 2 is in an isolated state.

[0030] At the same time, the nozzle 41, the three-way valves 42, and the three-way valves 42 are connected with each other through a transparent hose 44. The transparent hose 44 is connected with a flow meter and a pressure sensor. The transparent hoses 44 are connected with each other through the three-way valves 42 to form a complete loop, and only one air source is needed to detect multiple solenoid valves.

[0031] Visibly, the adapter assembly 5 includes an adapter plate 51 fixed on the nozzle 41 and fitting with the solenoid valve. The diameter of the adapter plate 51 is larger than the diameter of the solenoid valve port. A sealing ring 52 is fixed at the fitting position of the adapter plate 51 and the solenoid valve to seal the connection. A pressing cylinder 53 is installed between the adapter plate 51 and the hollow opening 22 to provide a pressing moment for the sealing ring 52 made of elastic material.

[0032] Obviously, a support platform 14 is installed at the lower end of the main body 1 and located below the detection station 2. The support platform 14 has a support block 15 fixed to the lower end of the main body 1 and a support plate 16 perpendicular to the support block 15. A limiting plate 17 that abuts against the lower end of the solenoid valve is provided at the upper end of the support plate 16. When the solenoid valve is inserted into the detection slot 21, the lower limiting plate 17 provides support and limitation. For different solenoid valves, the height of the limiting plate 17 can be adjusted for adaptation.

[0033] Preferably, 5 detection stations 2 are provided on the main body 1, and up to 5 solenoid valves can be detected at one time. The detection stations 2 are equipped with light sensors to judge whether the solenoid valves are accurately positioned, ensuring the accurate positioning of the clamping assembly 3 and the adapter assembly 5 with the solenoid valves.

[0034] In summary, the principle of this embodiment is that multiple detection stations 2 are provided on the main body 1 for the insertion of solenoid valves. The clamping assembly 3 clamps and fixes them, and the adapter assembly 5 conducts air. The air guiding assembly 4 adjusts the air flow path according to actual needs, and cooperates with the sensing elements to independently detect the internal medium flow state of each solenoid valve.

Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
