Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve body processing technology, specifically a positioning fixture for processing long slot holes in electromagnetic valve bodies. Background Technology

[0002] As a core component of fluid control systems, the precision of the solenoid valve body structure directly affects its sealing performance, response speed, and service life. The elongated slots on the valve body are typically used to install valve cores, guide components, or form specific flow channels, requiring extremely strict requirements for positional accuracy, symmetry, and dimensional tolerances. In traditional machining processes, elongated slots are often produced using milling or wire cutting, necessitating multiple clamping and positioning operations of the valve body to ensure the relative positional relationship between the machined surface and the reference surface.

[0003] Currently, the machining of long slots in valve bodies often uses general-purpose fixtures (such as flat-jaw pliers or three-jaw chucks) with locating pins or pads for clamping, which has the following problems:

[0004] Insufficient positioning accuracy: Valve bodies are mostly irregularly shaped, and general-purpose clamps are difficult to stably fit the reference surface, which can easily lead to the slot position being out of tolerance due to clamping offset;

[0005] Low repeatability: When processing different models of valve bodies, it is necessary to frequently change or adjust the fixture components, which affects the batch production cycle. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for machining long slots in solenoid valve bodies, which can improve the clamping effect on different solenoid valve bodies.

[0007] This utility model provides the following technical solution: a positioning fixture for machining long slots in the body of a solenoid valve, comprising a base, a support plate fixedly connected to the base, a V-shaped plate fixedly connected to the support plate, a groove provided on the V-shaped plate, a driving mechanism fixedly connected to the base, a fixing mechanism threadedly connected to the driving mechanism, a side plate and a side plate respectively fixedly connected to both sides of the base, a plurality of clamping components I arranged at equal intervals fixedly connected to the side plate I, and a plurality of clamping components II arranged at equal intervals fixedly connected to the side plate II.

[0009] Furthermore, the driver is a reversible motor.

[0010] Furthermore, the fixing mechanism includes a slider threadedly connected to a threaded rod, and a second V-shaped plate is fixedly connected to the slider, the second V-shaped plate having a second groove.

[0011] Furthermore, the clamping assembly includes a cylinder fixedly connected to a side plate, a rotating shaft fixedly connected to the front end of the cylinder, and connecting plates rotatably connected to both ends of the rotating shaft, with a pressing plate connected to both connecting plates.

[0012] Furthermore, the clamping assembly two includes a cylinder two fixedly connected to the side plate two, a rotating shaft two fixedly connected to the front end of the cylinder two, and connecting plates two rotatably connected to both ends of the rotating shaft two, and a pressing plate two connected to both connecting plates two.

[0013] Furthermore, the clamping component two and the clamping component one are symmetrical about the two sides of the base, and each clamping component two is independently controlled with respect to the clamping component one.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This positioning fixture for machining long slots in solenoid valve bodies can fix solenoid valve bodies of different models and sizes by adjusting the position of the fixing mechanism and by cooperating with clamping component one and clamping component two. Furthermore, the adjustment method is simple and quick, which can reduce adjustment time and improve the cycle time of mass production. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 2A positioning fixture for machining long slots in the body of a solenoid valve includes a base 1, a support plate 2 fixedly connected to the base 1, a V-shaped plate 3 fixedly connected to the support plate 2, a groove 4 formed on the V-shaped plate 3, a drive mechanism fixedly connected to the base 1, a fixing mechanism threadedly connected to the drive mechanism, a side plate 5 and a side plate 6 fixedly connected to the two sides of the base 1 respectively, a plurality of clamping components 1 arranged at equal intervals fixedly connected to the side plate 5, and a plurality of clamping components 2 arranged at equal intervals fixedly connected to the side plate 6.

[0021] like Figures 1 to 2 As shown, the positioning fixture for machining long slots in the body of a solenoid valve in this utility model first adjusts the position of the fixing mechanism through the drive mechanism so that the solenoid valve body can be placed on the fixing mechanism and V-plate 3, or in the groove 4 on the fixing mechanism and V-plate 3. Then, according to the length of the solenoid valve body, the number of clamping components 1 and 2 is selected, so that the clamping components 1 and 2 are used to squeeze and fix both sides of the solenoid valve body. The flanges at both ends of the solenoid valve body can be placed on the groove 4 on the fixing mechanism and V-plate 3. The fixing mechanism is adjusted again so that the solenoid valve body is clamped between the fixing mechanism and the groove 4 on the V-plate 3, thus initially fixing the solenoid valve body containing the flanges.

[0022] like Figure 1 As shown, the driving mechanism includes a fixed block 7 fixedly connected to the base 1, a driver 8 fixedly connected to the fixed block 7, a threaded rod 9 fixedly connected to the output end of the driver 8, the threaded rod 9 being rotatably connected to the fixed block 7 and the support plate 2, and a slide rod 10 fixedly connected between the fixed block 7 and the support plate 2.

[0023] Specifically, the driver 8 is activated, which causes the threaded rod 9 to rotate, thereby causing the fixing mechanism to move along the direction of the threaded rod 9 and the slide bar 10, thereby adjusting the distance between the fixing mechanism and the V-plate 3.

[0024] like Figure 1 As shown, the driver 8 is a forward and reverse rotating motor.

[0025] Specifically, the forward and reverse motor can make the threaded rod 9 rotate forward or backward, thereby adjusting the position of the fixing mechanism.

[0026] like Figure 1 As shown, the fixing mechanism includes a slider 11 threadedly connected to a threaded rod 9, a V-shaped plate 12 fixedly connected to the slider 11, and a groove 13 formed on the V-shaped plate 12.

[0027] Specifically, the rotation of the threaded rod 9 allows the slider 11 to move along the direction of the threaded rod 9 and the slide rod 10. Because the size and model of the solenoid valve body are different, some have flanges at both ends, and some have hexagonal columns at both ends. The flanges at both ends of the solenoid valve body are placed on groove 2 13 and groove 1 4 respectively. Through the driving mechanism, the flange at one end of the solenoid valve body can first abut against the inner wall of groove 2 13 and push the solenoid valve body to move. The flange at the other end of the solenoid valve body abuts against the inner wall of groove 1 4, thereby fixing the solenoid valve body. For solenoid valve bodies with hexagonal columns or other shapes at both ends, it is only necessary to adjust the distance between V-shaped plate 2 12 and V-shaped plate 1 3, place the solenoid valve body on V-shaped plate 2 12 and V-shaped plate 1 3, and use clamping component 1 and clamping component 2 to clamp both sides.

[0028] like Figure 1 As shown, the clamping assembly includes a cylinder 14 fixedly connected to a side plate 5. A rotating shaft 15 is fixedly connected to the front end of the cylinder 14. Both ends of the rotating shaft 15 are rotatably connected to connecting plates 16. A pressing plate 17 is connected to both connecting plates 16.

[0029] Specifically, after placing the solenoid valve body on V-shaped plate 2 12 and V-shaped plate 1 3, cylinder 1 14 is activated. Cylinder 1 14 pushes the rotating shaft 15 to move to one side of the solenoid valve body until the pressing plate 17 abuts against the solenoid valve body. The pressing plate 17 can rotate around the rotating shaft 15 through the connecting plate 16 to adjust according to the irregularities on the surface of the solenoid valve body, thereby strengthening the fixing effect.

[0030] like Figure 1 As shown, the clamping assembly 2 includes a cylinder 2 18 fixedly connected to the side plate 2 6. The front end of the cylinder 2 18 is fixedly connected to a rotating shaft 2 19. Both ends of the rotating shaft 2 19 are rotatably connected to a connecting plate 20. The two connecting plates 20 are connected to a pressing plate 21.

[0031] Specifically, cylinder 218 is activated, which pushes shaft 219 to move towards the other side of the solenoid valve body until the pressing plate 21 abuts against the solenoid valve body. The pressing plate 21 can rotate around shaft 219 via connecting plate 20 to adjust according to the irregularities on the surface of the solenoid valve body, thereby strengthening the fixing effect.

[0032] like Figures 1 to 2 As shown, the clamping component two and the clamping component one are symmetrical about the two sides of the base 1, and each clamping component two is independently controlled with respect to the clamping component one.

[0033] Specifically, depending on the length of the solenoid valve body, the clamping assembly 2 and clamping assembly 1 on the side closest to the V-shaped plate 3 can be activated in sequence to simultaneously squeeze and fix both sides of the solenoid valve body and limit its shaking.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
