Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve wiring technology, specifically a wiring device for a solenoid valve with a wire. 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. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most common types are check valves, safety valves, directional control valves, and speed control valves.

[0003] After the solenoid valve is manufactured, it needs to be tested for performance. During the performance test, the solenoid valve is usually installed in the test fixture and then oil is introduced. The valve body performance is checked by adjusting the pressure and flow parameters of the oil.

[0004] Before testing a solenoid valve, the leads and terminals of the solenoid coil must pass through the hollow hole of the flux sleeve (used to represent the installation position and matching conditions of the solenoid valve under actual working conditions). Especially during large-scale testing, manual threading is not only inefficient and can easily cause operator fatigue, but improper operation may also damage the coil leads or terminals.

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1 A wire-threading device for a solenoid valve includes a platform 1, a spring guide post 2 on the top of the platform 1, a linear bearing seat 3 slidably mounted on the top outer wall of the spring guide post 2, a circular helical spring 6 at the bottom of the linear bearing seat 3, a linear bearing 4 on the inner wall of the linear bearing seat 3, a linear guide shaft 5 on the top of the linear bearing 4, parallel pneumatic grippers 7 on both sides of the bottom of the platform 1, and a needle cylinder 12 on one side of the top of the linear bearing seat 3.

[0016] There are four spring guide posts 2, and a circular helical spring 6 is sleeved on the outer wall of the spring guide post 2. The two ends of the circular helical spring 6 are fixedly connected to the top of the platform 1 and the bottom of the linear bearing seat 3, respectively. There are two parallel pneumatic grippers 7, which are symmetrically distributed with the horizontal center line of the platform 1 as the center.

[0017] according to Figure 1-2 As shown, a gripper finger 8 is provided on one side of the parallel gripper 7, a DC brushless motor 9 is provided on the top of the gripper finger 8, a drive wheel 10 and a driven wheel 11 are provided on the bottom of the gripper finger 8, a wire harness sleeve 13 is provided at the bottom of the needle cylinder 12, an anti-detachment sleeve 14 is provided at the bottom of the wire harness sleeve 13, and a magnetic flux sleeve 15 is provided on the outside of the drive wheel 10.

[0018] The device includes two brushless DC motors 9, which are respectively positioned above the left and right sides of the two gripper fingers 8. The output shafts of the brushless DC motors 9 extend through the gripper fingers 8 to the bottom of the gripper fingers 8 and are fixedly connected to the drive wheels 10. The top of the driven wheels 11 is rotatably connected to the bottom of the gripper fingers 8 via a rotating shaft. The top of the magnetic flux sleeve 15 is movably connected to the inner sides of the two drive wheels 10 and the two driven wheels 11. The anti-detachment sleeve 14 and the wire harness sleeve 13 are located above the center of the magnetic flux sleeve 15.

[0019] In use, the DC brushless motor 9 is first installed on the gripper fingers 8 of the parallel gripper 7. A drive wheel 10 is installed at the output end of the DC brushless motor 9. When the parallel gripper 7 is closed, the drive wheel 10 and driven wheel 11 clamp the gear on the magnetic flux sleeve 15. When the DC brushless motor 9 rotates, the threads of the magnetic flux sleeve 15 begin to screw into the external threads of the solenoid valve. After the threads are screwed in, the magnetic flux sleeve 15 will have a downward stroke. To maintain the gripping wheels and prevent displacement between the drive wheel 10, driven wheel 11, and the gear on the magnetic flux sleeve 15, an elastic follower mechanism is designed. The follower mechanism consists of a linear guide shaft 5, a linear bearing 4, a circular helical spring 6, and a spring guide post 2. The elastic follower mechanism releases the stroke of the circular helical spring 6 to counteract the displacement of the magnetic flux sleeve 15 caused by screwing in. The gear on the drive wheel 10 meshes with the gear on the magnetic flux sleeve 15. Then, the DC brushless motor 9 starts to rotate, driving the drive wheel 10 and the magnetic flux sleeve 15 to fix the magnetic flux sleeve 15. Then: 1. The rod of the needle-type cylinder 12 extends out, and together with the wire harness sleeve 13 and the anti-detachment sleeve 14, passes through the hollow hole of the magnetic flux sleeve 15. 2. Move the anti-detachment sleeve 14 to the top. 3. Arrange the wire harness terminals 16 side by side and insert them sequentially into the slots of the wire harness sleeve 13. 4. Lower the anti-detachment sleeve 14 to the bottom, and the wire harness terminal 16 will no longer be able to fall off from the slot opening. 5. The needle cylinder 12 retracts, carrying the wire harness sleeve 13, the anti-detachment sleeve 14, and the wire harness terminal 16 through the magnetic flux sleeve 15 to complete the wire threading operation. The anti-detachment sleeve 14 is moved to the top, and the wire harness terminal 16 is taken out from the slot.

[0020] In summary, the wiring device for the solenoid valve with wire has the following advantages through the arrangement of the wire harness sleeve 13, the anti-derailment sleeve 14, the magnetic flux sleeve 15, and the wire harness terminal 16: 1. Wire harness sleeve 13: The end of the needle cylinder 12 rod can pass through the hollow hole of the magnetic flux sleeve 15 with the movement of the needle cylinder 12 rod; the wire harness sleeve 13 is designed with a slot to facilitate the installation of the wire harness terminal 16, which cannot fall off from the bottom and will not damage the connector terminal. 2. Anti-detachment sleeve 14: It is coaxially fitted with the wire harness sleeve 13 and can move axially. When it is moved to the bottom of the wire harness sleeve 13, it can prevent the connector from falling off from the side. When it is moved to the top of the wire harness sleeve 13, the connector can be taken out from the side. 3. Flux sleeve 15: Used to replace the installation and operating environment of the solenoid valve in actual working conditions; 4. Wiring harness terminal 16: The end wire of the solenoid valve coil.
