Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and more specifically, it relates to an adjustable valve processing fixture. Background Technology

[0002] Valves, as key components of fluid control systems, are widely used in petroleum, chemical, power, water treatment, pharmaceutical, and metallurgical industries. The manufacturing and processing of valves are related to their sealing performance, durability, and safety. Therefore, after forging, valves need to be milled and polished. However, the clamping fixtures currently used for polishing can easily partially obstruct the flanges of valves that require polishing on multiple sides. After polishing one side, the valve position needs to be changed, which increases processing time and reduces processing efficiency. Furthermore, valves of different sizes can cause different clamping force points, resulting in deviations in their stability.

[0003] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an adjustable valve processing tool to achieve a more practical purpose. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides an adjustable valve processing fixture to solve the issues of insufficient grinding efficiency caused by valve processing fixtures, and the fact that valves of different sizes are prone to different clamping force points, resulting in deviations in stability.

[0005] The purpose and effect of this utility model of an adjustable valve processing fixture are achieved by the following specific technical means:

[0006] An adjustable valve processing fixture includes a base, with symmetrically arranged support bodies on both sides of the base, and a side frame at the rear end of the base. The support body includes a side plate, and a fork-shaped bracket is installed on the side plate. A pad is detachably installed on the branch of the fork-shaped bracket. A pressure column is passed through the top of the side frame, and a horizontal block is installed at the bottom of the pressure column. Both ends of the horizontal block are provided with pressure rods.

[0007] Furthermore, the fork-shaped bracket is slidably mounted on the side plate, and a positioning bolt is provided at one end of the side plate. One end of the positioning bolt is inserted into the fork-shaped bracket and threadedly connected to it, while the other end is rotatably connected to the end of the side plate.

[0008] Furthermore, scale lines are provided on the side plate.

[0009] Furthermore, a sliding cavity is laterally formed inside the side frame, and the sliding cavity is connected to the hole through which the pressure column passes through the side frame. A pin block is slidably arranged inside the sliding cavity, and a triangular pin is connected to the front end of the pin block. Multiple toothed grooves are vertically formed on the side of the pressure column, and the inclined surface of the toothed grooves faces upward and matches the triangular pin. A telescopic rod is provided at the rear end of the pin block, and the telescopic rod passes through the side frame. A return spring is sleeved on the telescopic rod between the pin block and the sliding cavity.

[0010] Furthermore, the pressure column is provided with a movable groove, the horizontal block is slidably engaged in the movable groove, and a compression spring is provided between the horizontal block and the top of the movable groove.

[0011] Furthermore, a support strip is provided on the base between the two supports, and the top surface of the support strip is recessed to cooperate with the valve to be processed.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The valve end flange is supported by a fork-shaped bracket. The pressure column at the top presses down, causing the pressure rod to abut against the edge of the valve flange. This point contact and triangular compression fixing method increases stability without affecting the grinding and polishing of the valve end face. It can simultaneously grind the valve end faces of both ends and three ends (three-way valves), improving processing efficiency.

[0014] 2. The removable pads allow for the replacement of pads of different thicknesses on the fork bracket to accommodate valves of different sizes. This ensures that the circumferential angles of the two support points on the valve flange are consistent, guaranteeing consistent clamping and fixing stability. Attached Figure Description

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides an adjustable valve processing fixture, including a base 1, with symmetrical support bodies arranged on both sides of the base 1. The support bodies are used to support the inlet and outlet flanges at both ends of the valve or at the inlet and outlet.

[0026] The support body includes a side plate 301, on which a fork-shaped bracket 302 is mounted. A pad 303 is detachably installed on the branch of the fork-shaped bracket 302. The valve end flange is supported by the fork-shaped bracket 302. The inclined support at two points prevents the valve from sliding and rolling off. The detachable pad 303 allows the pads 303 of different thicknesses to be replaced on the fork-shaped bracket 302 according to different valve sizes. This ensures that the circumferential angles on the valve flanges at the two support points are consistent, guaranteeing consistent clamping and fixing stability.

[0027] A support bar 2 is provided on the base 1 between the two supports. The top surface of the support bar 2 is recessed and matches the valve to be processed. The support bar 2 can support the middle of the valve and increase the contact area of ​​the valve.

[0028] Before processing, a side frame 4 is provided at the rear end of the base 1. A pressure column 5 is passed through the top of the side frame 4. A horizontal block 8 is installed at the bottom of the pressure column 5, and pressure rods 9 are provided at both ends of the horizontal block 8. The pressure column 5 presses down so that the two pressure rods 9 abut against the edge of the valve flange. The three-point contact and triangular compression fixing of the fork bracket 302 and the pressure rod 9 increase its stability without affecting the polishing of the valve end face. The valve end faces of both ends and three ends (three-way valve) can be polished at the same time, which improves the processing efficiency.

[0029] The fork-shaped bracket 302 is slidably mounted on the side plate 301, and a positioning bolt 304 is provided at one end of the side plate 301. One end of the positioning bolt 304 is inserted into the fork-shaped bracket 302 and threadedly connected to it, while the other end is rotatably connected to the end of the side plate 301. By rotating the positioning bolt 304, the fork-shaped bracket 302 can be moved back and forth on the side plate 301, thereby adjusting the radial position of the two fork-shaped brackets 302, which can accommodate some valves whose inlets and outlets are not on the same axis.

[0030] The side plate 301 is equipped with scale lines 305, which can precisely adjust the position of the fork-shaped bracket 302 and read the value in real time.

[0031] like Figure 2 and Figure 3 As shown, a sliding cavity 15 is horizontally opened in the side frame 4. The sliding cavity 15 is connected to the pressure column 5 through the hole in the side frame 4. A pin block 10 is slidably arranged in the sliding cavity 15. A triangular pin 13 is connected to the front end of the pin block 10. The pin block 10 and the triangular pin 13 can slide horizontally in the sliding cavity 15. Multiple toothed grooves 14 are vertically opened on the side of the pressure column 5. The inclined surface of the toothed grooves 14 faces upward and matches the triangular pin 13. When the pin block 10 moves to the leftmost end, the triangular pin 13 can be inserted into one of the toothed grooves 14 to position the pressure column 5.

[0032] A telescopic rod 11 is provided at the rear end of the pin block 10. The telescopic rod 11 passes through the side frame 4, and a return spring 12 is sleeved on the telescopic rod 11 between the pin block 10 and the slide cavity 15. The return spring 12 squeezes the pin block 10, causing the triangular pin 13 to engage with the tooth groove 14 to position the pressure column 5. When the pressure column 5 is pressed down, the inclined surface of the tooth groove 14 in contact with the triangular pin 13 causes the downward pressure to generate a lateral force, which drives the triangular pin 13 to move into the slide cavity 15. After the triangular pin 13 moves into the next tooth groove 14 after it has shifted from one tooth groove 14, the return spring 12 can drive the triangular pin 13 to re-engage with the tooth groove 14. This design allows the pressure column 5 to move only downward and not upward, which is convenient for clamping and positioning the valve. When it is necessary to contact the valve for fixing, the telescopic rod 11 is pulled to disengage the triangular pin 13 from the tooth groove 14, which allows the pressure column 5 to move upward.

[0033] Because the positioning position of the downward movement of the pressure column 5 is affected by the size of the tooth groove 14, the pressure column 5 is provided with a movable groove 6, the horizontal block 8 is slidably locked in the movable groove 6, and a compression spring 7 is provided between the horizontal block 8 and the top of the movable groove 6. After the pressure column 5 moves down and the pressure rod 9 contacts the valve, if the triangular pin 13 is not just locked into the deepest part of the tooth groove 14 at this time, the pressure column 5 can continue to be squeezed downward, so that the triangular pin 13 is locked into the next tooth groove 14 to position the pressure column 5, and the valve can be pressed.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
