Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve testing technology, and in particular to a fixed fixture for electromagnetic valve testing. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Solenoid valves can be used with different circuits to achieve desired control, ensuring both precision and flexibility. Different solenoid valves function in different positions within a control system; the most common types are check valves, safety valves, and directional control valves.

[0003] The prior art patent document with publication number CN220104425U provides a solenoid valve testing fixture. The beneficial effect of this utility model is that, through the combined action of the set water tank, water pipe, submersible pump and flow detector, the internal leakage of the solenoid valve body can be detected during the use of the device. This prevents leakage caused by incomplete closure of some solenoid valve bodies due to poor internal sealing during the production process, thereby improving the product qualification rate of the solenoid valve body.

[0004] However, the solenoid valve testing fixture disclosed in the above patent has low fixing efficiency for solenoid valves during use and is not convenient for loading and unloading solenoid valves, thus reducing the efficiency of solenoid valve testing. Therefore, it is necessary to propose a fixing fixture for solenoid valve testing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fixing fixture for solenoid valve testing, so as to solve the problem mentioned in the background art that the existing solenoid valve testing equipment has low fixing efficiency for solenoid valves during use and is inconvenient for loading and unloading solenoid valves, thereby reducing the efficiency of solenoid valve testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed fixture for testing electromagnetic valves, including a testing platform, two symmetrically distributed support plates fixedly installed on the top of the testing platform, a hydraulic rod fixedly installed on the side of the support plate, a clamping plate fixedly installed on the telescopic end of the hydraulic rod, and an adjustment component installed on the side of the clamping plate;

[0007] The adjustment assembly includes a side ring, which is fixedly disposed on the edge of the side of the clamping plate. A sleeve rod is fixedly disposed on the inner wall of the side ring. Several sleeve rods are disposed in a ring and evenly distributed. A telescopic rod is slidably disposed inside the sleeve rod. A limit plate is fixedly disposed at one end of the telescopic rod that extends movably out of the sleeve rod end. A spring is fixedly connected between the limit plate and the inner wall of the side ring. The spring is movably sleeved on the outer ring of the sleeve rod and the telescopic rod. The end of the limit plate away from the clamping plate has an arc-shaped structure.

[0008] A detection assembly is provided between the clamping plate and the detection table;

[0009] A conveying assembly is provided on the top of the testing station.

[0010] Preferably, the detection assembly includes a sealing gasket, which is fixedly disposed on the side of the clamping plate. A water hole is opened in the middle of the clamping plate. A water pipe is fixedly disposed at the bottom of the clamping plate. The water pipe and the water hole are interconnected. A water tank is fixedly disposed at the top of the detection platform. A water pump is disposed at the top of the water tank. The water outlet of the water pump is connected to one of the water pipes. A flow detector is disposed on the other water pipe.

[0011] Preferably, the sealing gasket has a through hole in the middle that communicates with the water hole.

[0012] Preferably, the conveying assembly includes a chute, which is fixedly formed inside the testing table. A lead screw is rotatably arranged inside the chute, and a slider is threadedly connected to the outer ring of the lead screw. An electric push rod is fixedly arranged on the top of the slider, and a placement platform is fixedly arranged at the telescopic end of the electric push rod. An arc-shaped placement groove is formed on the upper surface of the placement platform.

[0013] Preferably, a handle is fixedly connected to one end of the lead screw that extends movably out of the front side of the testing platform.

[0014] Preferably, the slider and the groove are adapted to each other.

[0015] Preferably, the central axes of the two clamps are on the same horizontal line.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. In the process of using this utility model, the solenoid valve is placed between two clamping plates, and the two hydraulic rods are activated simultaneously to move the two clamping plates closer to each other. After the limit plates on both sides move closer to each other to adjust the solenoid valve, the solenoid valve is fixed. When it is necessary to unload the solenoid valve, the hydraulic rods are activated in the opposite direction to move the two clamping plates away from each other, so that the solenoid valve can be quickly disassembled. This solves the problem that the existing solenoid valve testing equipment has low fixing efficiency for solenoid valves and is inconvenient for unloading and loading solenoid valves, thus reducing the efficiency of solenoid valve testing.

[0018] 2. By installing the conveying assembly, place the solenoid valve on the placement slot, turn the handle to drive the lead screw to rotate, which in turn drives the slider, electric push rod and placement platform to move, so that the solenoid valve is approximately between the two clamping plates. Both flange ends of the solenoid valve cantilever out of the end of the placement platform. When the arc-shaped structure at the end of the limiting plate contacts the limiting plate, start the electric push rod to drive the placement platform to move downward, so that the limiting plates on both sides move closer to each other. After the solenoid valve is adjusted, it is fixed. There is no need to manually remove the solenoid valve to fix it, which improves the safety of the device detection.

[0019] 3. After the solenoid valve is fixed by installing the detection components, start the water pump. Water from inside the tank enters the water hole connected to it through one of the water pipes, then enters the solenoid valve, and is discharged from the other water hole to another water pipe. After the flow detector has a reading, the air inside the solenoid valve is purged. Then close the solenoid valve and continue to supply water to the inside of the solenoid valve. At this time, observe whether the flow detector has a reading to check the sealing performance of the solenoid valve, thus improving the convenience of device testing. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-4 The fixture shown includes a testing platform 1. Two symmetrically distributed support plates 2 are fixedly mounted on the top of the testing platform 1. Hydraulic rods 3 are fixedly mounted on the sides of the support plates 2. Clamping plates 4 are fixedly mounted on the telescopic ends of the hydraulic rods 3. The central axes of the two clamping plates 4 are on the same horizontal line. Adjustment components are provided on the sides of the clamping plates 4. The adjustment components include side rings 5, which are fixedly mounted on the edge of the side of the clamping plates 4. Sleeve rods 6 are fixedly mounted on the inner wall of the side rings 5. Several sleeve rods 6 are arranged in a ring and evenly distributed. Telescopic rods 7 are slidably mounted inside the sleeve rods 6. A limit plate 9 is fixedly mounted on one end of the telescopic rod 7 that extends movably out of the end of the sleeve rod 6. A spring 8 is fixedly connected between the limit plate 9 and the inner wall of the side ring 5. The spring 8 is movably sleeved on the outer ring of the sleeve rods 6 and the telescopic rod 7. The end of the limit plate 9 away from the clamping plate 4 has an arc-shaped structure.

[0027] In use, this invention places the solenoid valve between two clamping plates 4 and simultaneously activates two hydraulic rods 3, causing the clamping plates 4 to move closer together. The arc-shaped structure at the end of the limiting plate 9 guides the flange end of the solenoid valve between the limiting plates 9. Through the arrangement of the sleeve rod 6, telescopic rod 7, and spring 8, the limiting plates 9 apply equal thrust to the periphery of the flange end of the solenoid valve, thus aligning the flange end of the solenoid valve as closely as possible with the clamping plates 4. No manual alignment of the flange end of the solenoid valve with the clamping plates 4 is required. Once the flange end of the solenoid valve and the sealing gasket 10 are tightly fitted, the hydraulic rods 3 are stopped, completing the rapid fixation of the solenoid valve. When unloading the solenoid valve, the hydraulic rods 3 are activated in reverse, causing the clamping plates 4 to move away from each other, allowing for quick disassembly of the solenoid valve. This solves the problem of low fixing efficiency and inconvenience for unloading and loading solenoid valves in existing solenoid valve testing equipment, thereby reducing the efficiency of solenoid valve testing.

[0028] Furthermore, a detection assembly is provided between the clamping plate 4 and the detection platform 1. The detection assembly includes a sealing gasket 10, which is fixedly installed on the side of the clamping plate 4. A water hole 11 is opened in the middle of the clamping plate 4, and a through hole communicating with the water hole 11 is opened in the middle of the sealing gasket 10. A water pipe 12 is fixedly installed at the bottom of the clamping plate 4, and the water pipe 12 is communicating with the water hole 11. A water tank 16 is fixedly installed at the top of the detection platform 1, and a water pump is installed at the top of the water tank 16. The outlet of the water pump is connected to one of the water pipes 12, and a flow detector 17 is installed on the other water pipe 12.

[0029] After the solenoid valve is fixed, the water pump is started. Water from inside the water tank 16 enters through one of the water pipes 12 into the water hole 11 connected to it, then enters the solenoid valve, and is discharged from the other water hole 11 onto another water pipe 12. After the flow detector 17 has a reading, the air inside the solenoid valve is purged. Then the solenoid valve is closed, and water continues to be supplied to the inside of the solenoid valve. At this time, the flow detector 17 is observed to check whether it has a reading to check the sealing performance of the solenoid valve, thus improving the convenience of device testing.

[0030] Furthermore, a conveying assembly is provided on the top of the testing table 1. The conveying assembly includes a chute, which is fixedly opened inside the testing table 1. A lead screw 13 is rotatably installed inside the chute. A handle is fixedly connected to one end of the lead screw 13 that extends movably out of the front side of the testing table 1. A slider is threadedly connected to the outer ring of the lead screw 13. The slider and the chute are adapted to each other. An electric push rod 14 is fixedly installed on the top of the slider. A placement platform 15 is fixedly installed at the telescopic end of the electric push rod 14. An arc-shaped placement groove is opened on the upper surface of the placement platform 15.

[0031] Specifically, place the solenoid valve on the placement slot, turn the handle to rotate the lead screw 13, which in turn moves the slider, electric push rod 14, and placement platform 15, so that the solenoid valve is approximately positioned between the two clamping plates 4. Both flange ends of the solenoid valve protrude beyond the end of the placement platform 15. When the arc-shaped structure at the end of the limiting plate 9 contacts the limiting plate 9, start the electric push rod 14 to move the placement platform 15 downward, so that the limiting plates 9 on both sides move closer to each other to adjust the solenoid valve. Then fix it, without having to manually remove the solenoid valve to fix it, thus improving the safety of the device testing. After the solenoid valve test is completed, reverse the operation to pull the solenoid valve off.

[0032] Working Principle: In use, the solenoid valve is placed on the placement slot. Turning the handle rotates the lead screw 13, causing the slider, electric push rod 14, and placement platform 15 to shift, positioning the solenoid valve approximately between the two clamping plates 4. Both flange ends of the solenoid valve protrude beyond the ends of the placement platform 15. Simultaneously, the two hydraulic rods 3 are activated, causing the two clamping plates 4 to move closer together. When the arc-shaped structure at the end of the limiting plate 9 contacts the limiting plate 9, the electric push rod 14 is activated, causing the placement platform 15 to shift downwards, bringing the limiting plates 9 closer together to adjust the solenoid valve. After this adjustment, the solenoid valve is fixed between the two clamping plates 4, ensuring the clamping plates 4 and the solenoid valve are properly aligned. After aligning the flange ends of the solenoid valves and securing them, start the water pump. Water from inside the water tank 16 enters through one of the water pipes 12 into the connected water hole 11, then into the solenoid valve, and finally exits through the other water hole 11 onto another water pipe 12. Once the flow detector 17 registers a reading, the air inside the solenoid valve is purged. Then, close the solenoid valve and continue supplying water to its interior. At this point, observe whether the flow detector 17 registers a reading to check the solenoid valve's sealing performance. When it is necessary to unload the solenoid valve, reverse the hydraulic rod 3 to displace the two clamping plates 4 away from each other, allowing the solenoid valve to be quickly disassembled.
