Description

Technical Field

[0001] This utility model relates to a tooling fixture for assembling an electromagnetic valve core. Background Technology

[0002] In the manufacturing process of solenoid valves, valve core assembly is an extremely critical and precise step. The fit between the valve core and the valve body is highly precise, typically with very small clearances. During assembly, it is essential to strictly ensure that the coaxiality and clearance between the valve core and the valve body meet the design requirements. Otherwise, it will severely affect the flexibility of the valve core's movement and sealing performance, leading to unstable operation of the solenoid valve, sluggish action, jamming, or even leakage, greatly reducing the overall performance and reliability of the solenoid valve.

[0003] Traditional manual assembly methods have numerous limitations and cannot meet the stringent precision requirements of modern industry for solenoid valve assembly. During manual assembly, operators rely on visual inspection and experience to determine the valve core position. However, the accuracy of human visual inspection is limited, making it difficult to accurately judge the relative position of the valve core and the valve body mounting hole, easily leading to deviations. Furthermore, it is difficult for operators to maintain a consistently high level of hand stability; even slight tremors or uneven force can cause the valve core to deviate from its intended assembly position, compromising the consistency and repeatability of the assembly process. In addition, differences in operating habits and skill levels among operators result in inconsistent quality and poor product uniformity in manually assembled solenoid valves.

[0004] Therefore, a tooling fixture for assembling the valve core of an electromagnetic valve is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling fixture for assembling solenoid valve cores, so as to solve the problems of low precision and poor assembly effect of traditional manual valve core assembly mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a solenoid valve core assembly fixture, including a base, a support plate on the upper part of the base, a guide assembly for assembling the solenoid valve core on the support plate, and a fixing member for fixing the solenoid valve body located directly below the guide assembly.

[0007] The base clamps and fixes the solenoid valve body with a fastener, and then the solenoid valve core is linearly assembled into the valve core mounting hole of the solenoid valve body via a guide assembly.

[0008] Preferably, the guiding assembly includes a guide groove formed at the support plate, and a guide rod is disposed inside the guide groove.

[0009] The outer periphery of the guide rod is connected to a lateral adjusting rod via a guide slide plate. A guide plate is slidably connected to one side of the lateral adjusting rod. The front end of the guide plate has a guide hole that mates with the solenoid valve core, so that the solenoid valve core can move linearly through the guide hole.

[0010] Preferably, a reset spring is provided inside the guide groove, and the reset spring is located below the guide slide plate, so that the guide slide plate can be elastically reset inside the guide groove by the reset spring.

[0011] Preferably, the bearing plate has a transverse adjustment groove at the lower part of the guide vertical groove, the transverse adjustment groove is provided with a transverse slide rail inside, and a transverse sliding seat is slidably connected to the outside of the transverse slide rail. The front end of the transverse sliding seat is connected to the bearing sleeve through a connecting plate. A pre-aiming sleeve is detachably connected to the inside of the bearing sleeve, and the outer diameter of the pre-aiming sleeve matches the inner diameter of the valve core mounting hole of the solenoid valve body.

[0012] Preferably, the upper part of the connecting plate is provided with a vertical guide rail, and the vertical guide rail is connected to the guide plate. The middle part of the guide plate is provided with a vertical groove that cooperates with the vertical guide rail, so that the guide plate slides linearly on the upper part of the connecting plate through the vertical guide rail.

[0013] Preferably, the transverse adjustment groove is provided with an adjustment screw, the tail end of which is provided with an adjustment knob, and the adjustment knob is located on the side of the support plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention provides a precise linear movement path for the valve core through a specially designed guide component. In particular, the guide hole at the front end of the guide plate engages with the solenoid valve core, ensuring that the valve core moves accurately along the intended trajectory. This achieves high-precision assembly of the valve core and valve body, effectively solving the problem of valve core position deviation caused by the limited accuracy of human visual inspection in traditional manual assembly. It also meets the stringent requirements for coaxiality and fit clearance between the solenoid valve core and valve body.

[0018] The pre-aiming sleeve, which is detachably connected inside the bearing sleeve, has an outer diameter that matches the inner diameter of the valve core mounting hole in the solenoid valve body.

Furthermore, the detachable design of the pre-aiming sleeve allows for replacement according to the specific valve body model, further expanding the applicability of this tooling fixture. This enables it to meet the production and assembly requirements of various types of solenoid valves, reducing the cost for companies to purchase different types of assembly equipment.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-5 This utility model provides a tooling fixture for assembling a solenoid valve core, including a base 1, a support plate 2 on the upper part of the base 1, a guide assembly 3 for assembling the solenoid valve core on the support plate 2, and a fixing member 4 for fixing the solenoid valve body located directly below the guide assembly 3.

[0028] The guide assembly 3 includes a guide groove 31 formed in the support plate 2. A guide rod 32 is disposed inside the guide groove 31. A lateral adjusting rod 34 is connected to the outer periphery of the guide rod 32 via a guide slide plate 33. A guide plate 35 is slidably connected to one side of the lateral adjusting rod 34. The front end of the guide plate 35 has a guide hole 351 that mates with the solenoid valve core, so that the solenoid valve core can move linearly through the guide hole 351. A return spring 317 is disposed inside the guide groove 31, and the return spring 317 is located below the guide slide plate 33, so that the guide slide plate 33 can be elastically reset inside the guide groove 31 by the return spring 317. The support plate 2 has a horizontal adjustment groove 36 at the lower part of the guide vertical groove 31. A horizontal slide rail 37 is provided inside the horizontal adjustment groove 36. A horizontal sliding seat 38 is slidably connected to the outer side of the horizontal slide rail 37. The front end of the horizontal sliding seat 38 is connected to the support sleeve 310 via a connecting plate 39. A pre-aiming sleeve 311 is detachably connected inside the support sleeve 310, and the outer diameter of the pre-aiming sleeve 311 matches the inner diameter of the valve core mounting hole of the solenoid valve body. A vertical guide rail 312 is provided at the upper part of the connecting plate 39, and the vertical guide rail 312 is connected to the guide plate 35. A vertical sliding groove 313 is provided in the middle of the guide plate 35 to cooperate with the vertical guide rail 312, so that the guide plate 35 slides linearly on the upper part of the connecting plate 39 via the vertical guide rail 312. An adjusting screw 314 is provided inside the transverse adjusting groove 36. An adjusting knob 315 is provided at the tail end of the adjusting screw 314, and the adjusting knob 315 is located on the side of the support plate 2. A threaded adjusting hole 316 is provided in the middle of the transverse sliding seat 38, and the threaded adjusting hole 316 cooperates with the adjusting screw 314.

[0029] The fixing member 4 includes two sets of fixing plates 41 that slide linearly on the base 1, and the inner wall of the two sets of fixing plates 41 cooperates with the outer wall of the solenoid valve body.

[0030] The base 1 clamps and fixes the solenoid valve body with the fixing member 4, and then the solenoid valve core is linearly assembled into the valve core mounting hole of the solenoid valve body via the guide component 3.

[0031] The working principle of the electromagnetic valve core assembly fixture provided by this utility model is as follows:

[0032] First, place the solenoid valve body on the fixing part 4 of the base 1, and clamp and fix the valve body in a suitable position by moving the fixing plate 41 to ensure that the valve body is stable and does not move during the assembly process.

[0033] Place the pre-aiming sleeve 311, which mates with the valve core mounting hole, onto the bearing sleeve 310. Rotate the adjusting knob 315 to make the adjusting screw 314 rotate within the transverse adjusting groove 36. Since the threaded adjusting hole 316 in the middle of the transverse sliding seat 38 mates with the adjusting screw 314, the transverse sliding seat 38 will move along the transverse slide rail 37, thereby driving the guide assembly 3 to move horizontally until the pre-aiming sleeve 311 moves and inserts into the valve core mounting hole of the valve body.

[0034] Hold the upper part of the aiming sleeve 311 with your hand, leaving a gap for the valve core to pass through, to ensure that the valve core is inserted slowly and controllably. At this time, insert the solenoid valve core into the guide hole 351 of the guide assembly 3. The guide hole 351 provides a precise linear guide path for the valve core.

[0035] The operator pushes the valve core downwards via the guide plate 35 (the guide plate 35 slides on the outer periphery of the guide rod 32 via the guide slide plate 33, compressing the return spring 317, causing the return spring 317 to undergo elastic compression). The valve core moves along the guide hole 351 towards the valve core mounting hole in the valve body. The guide assembly 3 ensures that the valve core moves in a straight line, accurately aligning with the valve core mounting hole and inserting it. At this time, the fixing member 4 continuously stabilizes the valve body, preventing it from shifting or shaking during the valve core insertion process.

[0036] After assembly, the return spring 317 in the guide groove 31 comes into play. The return spring 317 is located below the guide slide plate 33. After the valve core is inserted into the valve body, the guide slide plate 33 returns to its initial position under the elastic action of the return spring 317, preparing for the next assembly.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
