Description

Technical Field

[0001] This utility model belongs to the technical field of solenoid valve fixing fixtures, and in particular relates to a fixing fixture for solenoid valve testing. Background Technology

[0002] With the acceleration of industrial automation and the widespread application of fluid control systems, solenoid valves, as actuators capable of precisely controlling the flow of fluids, are widely used in many industries such as chemical, hydropower, machinery manufacturing, and automotive. Their operational stability and control accuracy directly affect the operating efficiency and safety performance of the entire fluid system. Before solenoid valves are put into practical use, they must undergo rigorous testing for sealing performance, response speed, and pressure resistance. As a core auxiliary device in the testing process, the clamping stability and adaptability of solenoid valve testing fixtures directly affect the accuracy of test data and the efficiency of testing work. Therefore, high-performance solenoid valve testing fixtures are needed to provide reliable assurance for testing work.

[0003] However, the existing fixtures have a relatively simple fixing method, which can only fix the solenoid valve in one direction. The clamping stability is insufficient, and displacement is prone to occur during the testing process, which can cause the solenoid valve to loosen and affect the testing stability. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing fixture for testing solenoid valves. By setting a fixing part, it solves the problem that the existing fixing fixtures have a relatively simple fixing method during use, which can only fix the solenoid valve in one direction, resulting in insufficient clamping stability, easy displacement during testing, and loosening of the solenoid valve, thus affecting the stability of the test.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a fixing fixture for testing electromagnetic valves, comprising a support frame, and further comprising: two electromagnetic valve sections, which are arranged in a mirror image on the front side of the support frame; two fixing sections, which are arranged in a mirror image above the support frame; two rotating sections, which are arranged in a mirror image on the top of the support frame; each fixing section includes a fixing assembly, which is arranged above the support frame; and a power assembly, which is mounted on the fixing assembly; the fixing assembly includes a cross plate arranged above the support frame, the front side of which is fixed. A product fixing block is connected, and a detection block is fixedly connected to the product fixing block. Two fixing columns are fixedly connected to the detection block. A power component is provided on the cross plate, and a connector is installed below the product fixing block. The detection block is model KQF1330F. The power component includes a cylinder fixedly connected to the front side of the cross plate. A pre-pressure column fixing block is fixedly connected to the output end of the cylinder. A pre-pressure column is provided on the detection block. The pre-pressure column is located below the pre-pressure column fixing block. The connector includes a lower air nozzle fixing block fixedly connected to the lower part of the product fixing block. A through-plate connector passes through the lower air nozzle fixing block. The through-plate connector communicates with the detection block.

[0006] Furthermore, the solenoid valve section includes a solenoid valve disposed below the cross plate, and a lock nut straight connector is connected to the solenoid valve. A filter nozzle is connected to the side of the lock nut straight connector away from the solenoid valve.

[0007] Furthermore, the rotating part includes a vertical beam fixedly connected to the top of the support frame, a rotary cylinder fixedly connected to the front side of the vertical beam, and a plurality of fixed columns 2 fixedly connected to the output end of the rotary cylinder, and each of the plurality of fixed columns 2 fixedly connected to the cross plate; there are four fixed columns 2 arranged in a circular array.

[0008] Furthermore, the power assembly includes a second cylinder fixedly connected to the front side of the cross plate, and a fixing member is provided at the output end of the second cylinder; the second cylinder is located on the left side of the cross plate, and the fixing member includes a side nozzle fixing block fixedly connected to the output end of the second cylinder; the side nozzle fixing block is adapted to the product fixing block and the detection block.

[0009] This utility model has the following beneficial effects: 1. By setting up a fixing part, during use, the solenoid valve is placed on the product fixing block and the detection block. The cylinder one drives the pre-pressure column fixing block to move and squeeze the pre-pressure column to complete the fixing. Together with the product fixing block, the solenoid valve is clamped in the vertical direction. Then, the cylinder two pushes the side air nozzle fixing block close to the solenoid valve, and the lateral fixing and air circuit connection are completed simultaneously. With the coordinated adjustment of cylinder one and cylinder two, the on and off control of the solenoid valve air inlet is realized. The solenoid valve is fixed in multiple directions in the vertical and lateral directions. The clamping stability is strong, and the displacement during the detection process is avoided from affecting the stability of the detection. The operation process is simplified and the detection efficiency is improved. 2. By setting up a rotating part, after the rotary cylinder is started, its output end drives the cross plate to rotate through the fixed column two, which in turn drives the solenoid valve carried by the cross plate to rotate synchronously. The integrated transmission structure simplifies the angle adjustment process, improves the overall operation efficiency, and is suitable for automated detection scenarios.

[0018] It should be noted that the control of the two cylinders 215, the two cylinders 221, and the two rotary cylinders 312 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0019] A specific application of this embodiment is as follows: In use, the solenoid valve 112 is placed on the product fixing block 212 and the detection block 213.

With the cooperation of the pre-pressure column fixing block 216 and the product fixing block 212, the solenoid valve 112 is fixed up and down. Then, the second cylinder 221 is activated, which pushes the side air nozzle fixing block 222 closer to the solenoid valve 112 to fix and connect the solenoid valve 112. The rotary cylinder 312 is activated, and the output end of the rotary cylinder 312 drives the cross plate 211 to rotate through the second fixing block 313, thereby driving the solenoid valve 112 to rotate. The air inlet of the solenoid valve 112 is blocked and opened by the first cylinder 215 and the second cylinder 221.

[0020] It should be added that during the test, the first step is to test the air tightness of the iron head, with the rubber head facing upwards, no power on, air entering through port B, and port C blocked. Port A does not need to be blocked. This is the original state of the product after it is clamped. Step 2: After turning the product around, test the air tightness of the glue head with the iron head facing upwards. The voltage and current can be adjusted to 1-24V and 1-1000mA. Air enters through port B, and port A is blocked. Port C does not need to be blocked. At the same time, the internal resistance can be tested - this is the state of the product after rotation. Step 3: Measure the exhaust time. With the iron head facing up and no power on, air enters through port B. Block port A. Port C does not need to be blocked. The product is still in the state after rotation. The exhaust capacity can be switched between 100CC and 500CC. Working principle: Through electrical coordination, the product's airtightness and exhaust performance are tested to ensure they meet the requirements. The flip test tightens the testing standards, checking whether the product can exhaust normally when reversed. This achieves automatic tube insertion, solving the complexity of the original manual tube insertion test.
