[0045] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0046] Combination Figures 1 to 8 As shown, an assembly and positioning fixture for valve faucet production includes a mounting base 1 and a positioning component 2. The mounting base 1 has a mounting cavity 11 and a positioning groove 12. The positioning component 2 is disposed in the mounting cavity 11 and extends to the outside of the mounting base 1 for clamping and fixing the valve faucet onto the mounting base 1.

[0047] The system incorporates a positioning component on the mounting base. This component can adapt to valve cores of different sizes and shapes, clamping and fixing valve cores of varying specifications onto the mounting base to ensure they do not shift during assembly. This is crucial for ensuring assembly quality. Furthermore, it allows for the convenient installation of components such as bushings and gaskets onto the valve faucet, significantly improving the overall assembly efficiency of the control valve.

[0048] Specifically, a column 13 is provided at the center of the mounting cavity 11, and a positioning component 2 is sleeved on the column 13. The positioning component 2 includes: a drive plate 21, a mounting block 22, a slider 24, a clamping plate 25, a connecting plate 26, a drive screw 27, and a drive handle 28. A triangular drive plate 21 is rotatably mounted on a column 13. Multiple mounting blocks 22 are arranged around the drive plate 21, and a first groove 23 is provided on the mounting block 22. A slider 24 is slidably embedded in the first groove 23. A clamping plate 25 is provided on one side of the slider 24, and the top end of the clamping plate 25 passes through the mounting base 1 and extends to the outside of the mounting base 1. One end of the connecting plate 26 is rotatably connected to the lower part of the slider 24, and the other end of the connecting plate 26 is rotatably connected to the upper part of the drive plate 21. A drive screw 27 is rotatably mounted on the mounting base 1, one end of the drive screw 27 extends into the mounting cavity 11 and is rotatably connected to one of the sliders 24, and the other end of the drive screw 27 extends to the outside of the mounting base 1. A drive handle 28 is mounted on the end of the drive screw 27 that extends to the outside of the mounting base 1.

[0049] Among them, will be as follows Figure 1 The workpiece is placed in the positioning groove 12 on the mounting base 1. Next, the operator rotates the handle 28, and the drive screw 27 rotates accordingly. The rotation of the drive screw 27 will drive the slider 24 to move the clamping plate 25 to slide on the track of the mounting block 22. Since one end of the connecting plate 26 is rotatably connected to the lower part of the slider 24 and the other end is rotatably connected to the upper part of the drive plate 21, this allows the movement of the slider 24 to be synchronized with the rotation of the drive plate 21. While the drive plate 21 rotates relative to the column 13, the drive plate 21 drives the other connecting plates 26, the connecting plates 26 drive the corresponding sliders 24, and the sliders 24 drive the clamping plates 25 to slide on the track of the mounting block 22, so that the corresponding clamping plates 25 synchronously perform clamping actions on the workpiece to fix the corresponding workpiece on the mounting base 1.

[0050] Combination Figure 3 , Figure 4 and Figure 6 As shown, a limiting groove 241 is provided on one side of the slider 24 that is rotatably connected to the drive screw 27; a rotating block 271 is provided at the end of the drive screw 27 that is rotatably connected to one of the sliders 24, and the rotating block 271 is rotatably embedded in the limiting groove 241. The limiting groove 241 has a convex shape.

[0051] The rotating block 271 is rotatably embedded in the limiting groove 241. The limiting groove 241 has a convex structure, which can ensure the connection stability between the drive screw 27 and one of the sliders 24. The rotating block 271 serves as the connecting component between the drive screw 27 and the slider 24, converting the rotational motion of the drive screw 27 into the linear motion of the slider 24.

[0052] Combination Figure 3 and Figure 8 As shown, the mounting base 1 has multiple second sliding grooves 14, and the clamping plate 25 is slidably embedded in the second sliding grooves 14. The number of clamping plates 25 is the same as the number of second sliding grooves 14, and one side of the clamping plate 25 is set with an arc-shaped structure.

[0053] The second slide groove provides guidance and positioning for the clamping plate. The clamping plate slides within the second slide groove, ensuring stability during movement and preventing unnecessary shaking or offset. The number of second slide grooves matches the number of clamping plates, ensuring that each clamping plate has a corresponding slide groove, allowing for individual or synchronous control of the position and movement of each clamping plate. Simultaneously, one side of the clamping plate 25 is designed with an arc shape, ensuring that its structure perfectly matches the workpiece structure. The arc-shaped clamping plate better conforms to the workpiece surface, providing a more uniform and stable clamping force.

[0054] Figure 6 and Figure 7 As shown, a limiting component 3 is provided on the upper part of the clamping plate 25. The limiting component 3 includes a fixing plate 31, a spring 32, and a limiting block 33. The spring 32 is located at the lower part of the fixing plate 31; the limiting block 33 is slidably disposed on one side of the clamping plate 25, and the upper part of the limiting block 33 is connected to the bottom end of the spring 32. A guide groove 251 is provided on the clamping plate 25; a guide block 331 is provided on one side of the limiting block 33, and the guide block 331 is slidably embedded in the guide groove 251. An inclined chamfer 332 is provided on the other side of the limiting block 33.

[0055] In this way, under the action of the inclined chamfer 332, when the clamping plate 25 gradually approaches the workpiece, the workpiece of different specifications will exert a certain squeezing force on the limiting block 33, and the spring 32 will gradually be compressed until the limiting block 33 is located above the workpiece. Under the joint action of the spring 32, the workpiece is fixedly clamped. At the same time, under the combined action of the guide groove 251 and the guide block 331, the sliding of the limiting block 33 is guided.

[0056] The working principle of this utility model is as follows:

[0057] Place the valve faucet workpiece to be assembled into the positioning groove 12 of the mounting base 1, ensuring the workpiece is in the correct assembly position. The operator rotates the drive handle 28, causing the drive screw 27 to rotate accordingly. The rotation of the drive screw 27 drives the slider 24, which is connected to one end, to move along the first slide groove 23. Since the upper end of the connecting plate 26 is rotatably connected to the drive plate 21 and the lower end is rotatably connected to the slider 24, the linear motion of the slider 24 is converted into the rotational motion of the drive plate 21 through the connecting plate 26. The rotation of the drive plate 21 drives the clamping plate 25 on the mounting block 22 to move synchronously, causing the clamping plate 25 to slide along the second slide groove 14 on the mounting base 1. During the sliding process, the clamping plate 25, due to its arc-shaped structure, can better fit the surface of the workpiece, improving the fit. Provides uniform and stable clamping force. As the clamping plate 25 gradually approaches the workpiece, the limiting block 33 is subjected to the workpiece's squeezing force, and the spring 32 is compressed. When the limiting block 33 reaches the upper position of the workpiece, the elastic force of the spring 32 and the inclined chamfer 332 of the limiting block 33 work together to fix and clamp the workpiece. The guide groove 251 and the guide block 331 are combined to guide the sliding of the limiting block 33, ensuring the stability and accuracy of the clamping process. After the clamping plate 25 fixes the workpiece on the mounting base 1, the operator can easily install components such as bushings and sealing gaskets. After assembly, the operator rotates the drive handle 28 again, and the drive screw 27 rotates in the opposite direction. The clamping plate 25 then returns to its original position, releasing the clamping of the workpiece.

[0058] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
