Detailed Implementation
[0021] 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.
[0022] The solenoid valve mentioned in this utility model is mainly used in automotive oil pump systems to control the opening and closing of the oil pump circuit. Due to differences in oil pump types, the fixed position of the solenoid valve differs from that of the oil pump; therefore, the key difference lies in the angle between the center line of the bracket and the center line of the coil. The structure of the solenoid valve is as follows... Figure 4 As shown, it mainly includes a bracket 15, a housing 16, a coil 17, etc. A top view of the solenoid valve compatible with this embodiment is shown below. Figure 5 As shown, the main difference lies in the angle between the centerline of the solenoid valve bracket and the centerline of the solenoid valve coil.
[0023] The present invention provides a compatible tooling for assembling various types of solenoid valves, such as... Figure 1 As shown, the fixture includes a tooling body 1, the top surface of which has a positioning surface for placing a solenoid valve; the positioning surface has a valve core positioning hole 2, and an annular housing groove 4 concentric with the valve core positioning hole is formed around the valve core positioning hole; on one side of the valve core positioning hole 2, the positioning surface has a coil positioning groove 6 along the radial direction A of the valve core positioning hole 2; the positioning surface has four bracket-shaped grooves 5 formed by rotating around the center of the valve core positioning hole 2 as the center and the radial direction A of the valve core positioning hole 2 as the starting line, at different angles α. The positioning surface is rotated around the center of the valve core positioning hole 2 as the center and the radial direction A of the valve core positioning hole 2 as the starting line, at different angles α, where the angle α may be 45 degrees, 167 degrees, 225 degrees, or 300 degrees, to accommodate various configurations such as... Figure 5 The different types of solenoid valves shown.
[0024] like Figure 1-3As shown, on the positioning surface, a protruding column 3 is formed between the valve core positioning hole 2 and the housing groove 4, which facilitates the fixing and positioning of the solenoid valve housing 11. The end of the protruding column 3 is rounded to improve lubrication and reduce frictional resistance. Starting from the left side of the positioning surface, a robotic arm movable groove 8 is provided towards the valve core positioning hole 2. The depth of the robotic arm movable groove 8 is greater than the bracket irregular groove 5 but less than the depth of the housing groove 4, so as to facilitate the robotic arm to pick up the solenoid valve and prevent interference. A valve sleeve positioning groove 9 is provided on the right side of the robotic arm movable groove 8, which is used to store the material valve sleeve 13 of the next process. The lower right center of the tooling body 1 is hollowed out, which can save materials, reduce costs, and facilitate the staff to pick up the tooling when changing the tooling. Several positioning holes 7 are provided on the top of the tooling body 1, which are used to position the equipment of the next process to grab the material of the previous process. Several positioning holes 10 are provided on the bottom of the tooling body 1, which are used to position the tooling with the tray. Several fixing bolt holes 11 are provided on the tooling body 1, which are used to fix the tooling with the tray.
[0025] During assembly, first place the bracket 12 into the tooling body 1. At this time, the surface of the bracket 12 is in close contact with the surface of the protruding column 3 formed between the valve core positioning hole 2 and the housing groove 4 of the tooling body 1. The irregular part of the bracket 12 is placed in the irregular groove 5 of the bracket. The irregular groove 5 of the bracket and the protruding column 3 are on the same horizontal plane. Then, the coil 14 is installed into the specific housing groove 4 of the housing 13. This assembled part is placed in the tooling body 1. At this time, the surface of the coil 14 is in close contact with the surface of the bracket 12. The coil 14 is placed along the direction of the coil positioning groove 6 on the positioning surface of the tooling body. Then, the wide end of the valve sleeve 15 is placed in the valve sleeve positioning groove 9 on the positioning surface of the tooling body 1. This process is completed. When the next pallet flows into this station, the above operation is repeated again.
