Description

Technical Field

[0001] This utility model relates to the field of valve body processing technology, specifically to a wedge tool for aligning a filter valve body. Background Technology

[0002] In modern industrial production, filter valve bodies are key components that ensure the stable operation of fluid systems, making their manufacturing precision and assembly quality crucial. Currently, filter valve bodies are mostly manufactured using casting processes. While this process can meet the needs of large-scale production, it is difficult to guarantee the consistency of the hole positions at the valve body ends.

[0003] In existing technologies, due to various factors affecting the casting process, such as mold precision, molten metal flow state, and uneven cooling rate, each valve body will have a certain degree of deviation in size and shape. This leads to the fact that in the subsequent assembly process, traditional assembly methods are prone to misalignment due to valve body position shift. Once the valve body is misaligned, it affects the appearance quality of the entire filtration system, resulting in problems such as poor sealing and fluid leakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a wedge tool for aligning a filter valve body, comprising: a tooling base plate, a positioning hole formed in the wall of the tooling base plate, a valve body slidably connected to the inner wall of the positioning hole, pressure plates symmetrically arranged on the outside of the valve body, a sliding groove formed in the outer wall of the tooling base plate, a wedge block slidably connected to the inner wall of the sliding groove, an installation hole formed in the outer wall of the tooling base plate, and a through groove formed in the inner wall of the sliding groove.

[0005] Preferably, the outer wall of the bottom end of the valve body is slidably connected to the inner wall of the positioning hole, and the outer wall of the pressure plate is slidably connected to the outer wall of the valve body. The valve body to be aligned is placed into the positioning hole, which initially limits the valve body's position, ensuring that the outer wall of the bottom end of the valve body slides against the inner wall of the positioning hole, thus preventing significant displacement of the valve body during initial placement.

[0006] Preferably, a positioning screw is slidably connected to the inner wall of the pressure plate, and an installation rod is fixedly connected to the outer wall of the bottom end of the pressure plate. The installation rod at the bottom end of the pressure plate is aligned with the installation hole, allowing the installation rod to slide within the installation hole, thus achieving initial positioning of the pressure plate on the tooling base plate. Simultaneously, the positioning screw slidably connected to the inner wall of the pressure plate is aligned with the corresponding threaded hole on the tooling base plate. Rotating the positioning screw causes the pressure plate to move downwards along the axis of the positioning screw, as the outer wall of the positioning screw is threadedly connected to the inner wall of the tooling base plate.

[0007] Preferably, the outer wall of the positioning screw is threaded to the inner wall of the tooling base plate, and the outer wall of the mounting rod is slidably connected to the inner wall of the mounting hole. The pressure plate moves downward along the axis of the positioning screw until the outer wall of the pressure plate is tightly slidably fitted against the outer wall of the valve body, generating sufficient clamping force on the valve body. Through the combined action of the two symmetrically arranged pressure plates, the aligned valve body is firmly fixed to the tooling base plate.

[0008] Preferably, the inner wall of the wedge block is threaded with a limit screw, and the outer wall of the wedge block is symmetrically fixedly connected with end face blocks. The wedge block located at the large end of the sliding groove is pushed, causing it to slide along the inner wall of the sliding groove towards the valve body. The outer wall of the wedge block is symmetrically fixedly connected with end face blocks. During the sliding process, the contact between the end face blocks and the outer wall of the valve body is continuously observed until the outer walls of the two end face blocks of the wedge block are completely slidably contacted with the outer wall of the valve body.

[0009] Preferably, the outer wall of the end face block is slidably connected to the outer wall of the valve body, the outer wall of the limiting screw is slidably connected to the inner wall of the through groove, and the bottom end of the limiting screw is slidably connected to the bottom outer wall of the tooling base plate. Tightening the limiting screw, the wedge block is fixed in its current position by the threaded connection between the limiting screw and the wedge block and the sliding limiting effect with the through groove, preventing the wedge block from shifting during subsequent operations and causing the valve body to deviate from its correct position.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention utilizes a combination structure of wedge blocks and end face blocks, based on the principle that two points determine a straight line. The end face blocks, symmetrically fixed to the outer wall of the wedge blocks, adhere to the outer wall of the valve body, forcibly correcting positional deviations caused by casting. This adjusts the valve body to a uniform reference position. During the fixing stage, the mounting rod and mounting hole provide rapid positioning, and the positioning screw rotates and tightens. Two symmetrically arranged pressure plates apply stable pressure from both sides of the valve body through the clamping force of the positioning screw, ensuring the valve body fits tightly against the tooling base plate. This achieves rapid fixing of the valve body by the pressure plates. The entire process eliminates cumbersome procedures, significantly shortening the time for valve body alignment and fixing, substantially improving operational efficiency on the production line, and reducing labor costs.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art.

[0018] Example:

[0019] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a wedge tool for aligning a filter valve body, comprising: a tooling base plate 1, a positioning hole 3 in the wall of the tooling base plate 1, a valve body 2 slidably connected to the inner wall of the positioning hole 3, pressure plates 4 symmetrically arranged on the outside of the valve body 2, a sliding groove 9 in the outer wall of the tooling base plate 1, a wedge block 5 slidably connected to the inner wall of the sliding groove 9, an installation hole 8 in the outer wall of the tooling base plate 1, and a through groove 12 in the inner wall of the sliding groove 9.

[0020] The bottom outer wall of valve body 2 is slidably connected to the inner wall of positioning hole 3, and the outer wall of pressure plate 4 is slidably connected to the outer wall of valve body 2.

[0021] The inner wall of the pressure plate 4 is slidably connected with a positioning screw 7, and the bottom outer wall of the pressure plate 4 is fixedly connected with an installation rod 6.

[0022] The outer wall of the positioning screw 7 is threaded to the inner wall of the tooling base plate 1, and the outer wall of the mounting rod 6 is slidably connected to the inner wall of the mounting hole 8.

[0023] The inner wall of the wedge block 5 is threaded with a limit screw 10, and the outer wall of the wedge block 5 is symmetrically fixed with an end face block 11.

[0024] The outer wall of the end face block 11 is slidably connected to the outer wall of the valve body 2, the outer wall of the limiting screw 10 is slidably connected to the inner wall of the through groove 12, and the bottom end of the limiting screw 10 is slidably connected to the bottom outer wall of the tooling base plate 1.

[0025] Working principle:

[0026] When in use, first loosen the limiting screw 10 connected to the inner wall of the wedge block 5. Since the outer wall of the limiting screw 10 is slidably connected to the through groove 12 of the inner wall of the sliding groove 9 of the tooling base plate 1, and its bottom end slides with the bottom outer wall of the tooling base plate 1, after loosening, the wedge block 5 can be pushed to move in the sliding groove 9. Push the wedge block 5 to the large end of the sliding groove 9 to leave enough space for the valve body to be placed later. Place the valve body 2 to be aligned into the positioning hole 3. Use the positioning hole 3 to initially limit the valve body 2, so that the bottom outer wall of the valve body 2 slides and fits with the inner wall of the positioning hole 3, ensuring that the valve body 2 will not deviate significantly when initially placed.

[0027] Push the wedge block 5 located at the large end of the sliding groove 9 to slide it along the inner wall of the sliding groove 9 towards the valve body 2. The outer wall of the wedge block 5 is symmetrically fixed with end face blocks 11. During the sliding process, continuously observe the fit between the end face blocks 11 and the outer wall of the valve body 2 until the outer walls of the two end face blocks 11 of the wedge block 5 are completely slidably fitted with the outer wall of the valve body 2. Through the precise fit between the two end face blocks 11 and the outer wall of the valve body 2, the positional offset of the valve body 2 caused by casting errors is forcibly corrected, allowing the valve body 2 to be adjusted to the correct reference position, completing the alignment. After alignment, tighten the limiting screw 10. Utilize the threaded connection between the limiting screw 10 and the wedge block 5, as well as the sliding limiting effect with the through groove 12, to fix the wedge block 5 in its current position, preventing the wedge block 5 from shifting during subsequent operations and causing the valve body 2 to deviate from its correct position.

[0028] Align the mounting rod 6 at the bottom of the pressure plate 4 with the mounting hole 8, and slide the mounting rod 6 in the inner wall of the mounting hole 8 to achieve the initial installation and positioning of the pressure plate 4 on the tooling base plate 1. At the same time, align the positioning screw 7, which is slidably connected to the inner wall of the pressure plate 4, with the corresponding threaded hole on the tooling base plate 1. Rotate the positioning screw 7. Since the outer wall of the positioning screw 7 is threadedly connected to the inner wall of the tooling base plate 1, as the positioning screw 7 rotates, it drives the pressure plate 4 to move downward along the axis of the positioning screw 7 until the outer wall of the pressure plate 4 slides tightly against the outer wall of the valve body 2, and generates sufficient clamping force on the valve body 2. Through the combined action of the two symmetrically arranged pressure plates 4, the aligned valve body 2 is firmly fixed on the tooling base plate 1, preventing the valve body 2 from changing position during subsequent processing or assembly, and ensuring that the valve body 2 is always in the correct position.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
