Description

Technical Field

[0001] This invention relates to the field of tooling and fixture technology, and in particular to a valve processing positioning tooling. Background Technology

[0002] In modern industrial manufacturing, valves, as key components for controlling fluid flow, play a vital role in various piping systems. However, in the valve manufacturing process, especially when it comes to the connection between the flange and the cylinder, traditional manual assembly methods have revealed a series of problems.

[0003] Precise positioning is difficult to achieve manually, especially when dealing with non-standard geometries such as elliptical cylinders. Their irregular shape makes precise alignment between the two flanges and the cylinder extremely challenging. Furthermore, manual assembly is inefficient and susceptible to operator skill levels, increasing the likelihood of assembly errors and impacting production efficiency and product quality. More importantly, inaccurate positioning between the flanges and the cylinder can create leaks during subsequent welding processes, severely compromising the valve's overall performance and reliability. Summary of the Invention

[0004] This application provides a valve processing positioning fixture, which solves the technical problem of poor accuracy in manual valve assembly in the prior art.

[0005] This application provides a valve machining positioning fixture, including:

[0006] A base plate, wherein a first positioning post is provided on the base plate;

[0007] The bracket is fixedly mounted on the base plate;

[0008] The second positioning post is fixedly mounted on the bracket, and the first positioning post and the second positioning post are coaxially arranged.

[0009] The first limiting block is fixedly mounted on the base plate.

[0010] In some embodiments, the bracket is provided with a clearance mechanism corresponding to the first positioning post below it.

[0011] In some embodiments, a reinforcing rib is provided between the bracket and the base plate.

[0012] In some embodiments, the upper end of the first limiting block is higher than the upper end of the second positioning post.

[0013] In some embodiments, a second limiting block is further provided on the base plate, and the second limiting block is slidably disposed on the base plate.

[0014] In some embodiments, a sliding groove is provided on the base plate, a slider is provided at the lower end of the second limiting block, the second limiting block is slidably disposed in the sliding groove by the slider, a baffle is provided at the end of the sliding groove, a lead screw is provided in the sliding groove along the length direction and passes through the slider and the baffle, the lead screw is rotatably connected to the inner wall of the sliding groove and the baffle, and the lead screw is threadedly engaged with the slider.

[0015] The beneficial effects of this application are as follows:

[0016] The valve processing positioning fixture provided in this application first mates one flange with the first positioning post, then places the cylinder on the lower flange, and then mates the other flange with the second positioning post, so that the two flanges clamp the cylinder in the middle. The two flanges abut against the first limiting block, so that the two flanges can automatically align during installation, reduce human intervention, improve the positioning accuracy between the flange and the cylinder, reduce manual operation, and improve production efficiency.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0023] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0024] This application provides a valve processing and positioning fixture, which solves the technical problem of poor accuracy in manual valve assembly in the prior art.

[0025] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0026] Example 1

[0027] like Figure 1 As shown, this application provides a valve machining positioning fixture, including:

[0028] Base plate 1, on which a first positioning post 2 is provided;

[0029] The bracket 3 is fixedly mounted on the base plate 1;

[0030] The second positioning post 4 is fixedly mounted on the bracket 3, and the first positioning post 2 and the second positioning post 4 are coaxially arranged.

[0031] The first limiting block 5 is fixedly mounted on the base plate 1. The upper end of the first limiting block 5 is higher than the upper end of the second positioning post 4, so that the flange can abut against the side of the first limiting block 5.

[0032] First, one flange is fitted with the first positioning post 2. Then, the cylinder is placed on the flange below. Next, the other flange is fitted with the second positioning post 4, so that the two flanges clamp the cylinder in the middle. The two flanges abut against the first limiting block 5, allowing the two flanges to automatically align during installation, reducing human intervention. The combination design of positioning posts and limiting blocks effectively improves the positioning accuracy between the flanges and the cylinder, reducing welding quality problems caused by inaccurate positioning. The use of tooling simplifies the assembly process, reduces manual operations, and thus improves production efficiency. At the same time, by reducing assembly errors and rework, the production cycle is further shortened.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Preferably, the support 3 is provided with a clearance below the first positioning post 2 to facilitate the placement of the cylinder below the support 3.

[0035] Furthermore, a reinforcing rib 6 is provided between the bracket 3 and the base plate 1. The reinforcing rib 6 improves the stability of the bracket 3 and prevents the bracket 3 from deforming during use.

[0036] Example 2

[0037] Preferred, such as Figure 2 As shown, a second limiting block 7 is also provided on the base plate 1, and the second limiting block 7 is slidably disposed on the base plate 1.

[0038] A sliding groove 8 is provided on the base plate 1. A slider 9 is fixedly provided at the lower end of the second limiting block 7. The second limiting block 7 is slidably disposed in the sliding groove 8 through the slider 9. A baffle 10 is provided at the end of the sliding groove 8. A lead screw 11 is provided in the sliding groove 8 along the length direction and passes through the slider 9 and the baffle 10. The lead screw 11 is rotatably connected to the inner wall of the sliding groove 8 and the baffle 10. The lead screw 11 is threadedly engaged with the slider 9. An adjustment handle 12 is fixedly provided at the end of the lead screw 11.

[0039] After the flange is installed on the first positioning post 2 and the second positioning post 4, the flange rests against the first limiting block 5, and the lead screw 11 is rotated by rotating the adjusting handle 12. During the rotation of the lead screw 11, the slider 9 moves relative to the lead screw 11, thereby causing the second limiting block 7 to move in the slide groove 8. The flange is limited by the first limiting block 5, the second limiting block 7, the first positioning post 2 and the second positioning post 4, so that the positioning accuracy between the flange and the cylinder can be further improved.

[0040] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.

[0041] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
