AI Technical Summary
During the manufacturing process of the ball valve body, burrs in the end flange hole may come into contact with the positioning rod, making it difficult to insert or causing damage to the positioning rod, thus affecting its service life.
A rubber sleeve is fitted onto the positioning rod and connected to the positioning rod by a pressure head threaded together. The deformability of the rubber sleeve allows it to deform within the hole to accommodate burrs and prevent the positioning rod from being scratched. At the same time, the rubber sleeve can be replaced separately to extend its service life.
This allows for smooth insertion of the positioning rod into the end flange hole, protecting the positioning rod from damage, extending the service life of the rubber sleeve, and facilitating positioning and deburring operations during processing.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve processing technology, and in particular to a ball valve processing anti-deviation mechanism. Background Technology
[0002] The integral casting of a ball valve body is a manufacturing process that involves pouring liquid metal or alloy directly into a mold, allowing it to cool and solidify to form a complete ball valve body structure without the need for subsequent welding or other connection methods. This method can improve the overall strength, sealing performance, and durability of the ball valve.
[0003] After the ball valve body is cast, two end flanges and one top flange will be formed on its surface. The holes on the end flanges and top flange need to be deburred by precision machining. Since the shape of the ball valve body is not a regular rectangle, a clamp is required for clamping. A clamp formed by inserting positioning rods on the end flanges of the ball valve body is used to restrict the position of the ball valve body during the ball valve processing.
[0004] To prevent the ball valve body from shaking during processing, the inner diameter of the positioning rod needs to be the same as the inner diameter of the hole on the end flange. However, after the positioning rod is inserted into the hole on the end flange, there is a possibility that the positioning rod cannot be smoothly inserted into the hole of the end flange with burrs, or that the burrs in the end flange hole will scratch the positioning rod, affecting its service life. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ball valve processing anti-deviation mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a ball valve processing anti-deviation mechanism, comprising:
[0007] The ball valve body has end flanges integrally formed at both ends and a top flange integrally formed at the top.
[0008] The base is located on the underside of the ball valve body;
[0009] Two clamping plates are provided, and the end flanges are arranged parallel to the clamping plates.
[0010] Positioning rods are installed on the middle of the upper surface of the base and on the opposite sides of the two clamping plates, with multiple positioning rods that mate with the holes on the end flanges.
[0011] A rubber sleeve is fitted onto the positioning rod, and multiple rubber sleeves are provided;
[0012] The pressure head is threadedly connected to one end of the positioning rod, thereby limiting the relative position of the rubber sleeve and the positioning rod;
[0013] The pressure plate is installed on the lower part of the side of the clamp plate facing the ball valve body, and cooperates with the positioning rod on the base to limit the position of the end flange.
[0014] A screw is rotatably mounted on both of the two clamping plates on opposite sides. The screw is threadedly connected to the base, and a handle is mounted on the end of the screw away from the clamping plate.
[0015] Optionally, the base may also include:
[0016] There are two ear seats, which are symmetrically installed on the upper surface of the base. Each ear seat has a screw hole on its opposite side, and the screw is threaded into the screw hole.
[0017] Optionally, the clamping plate further includes:
[0018] The T-shaped sliders are symmetrically installed on the lower surface of the clamping plate. The upper surface of the base has two T-shaped grooves on both sides of the ball valve body that mate with the T-shaped sliders. The T-shaped sliders are slidably installed in the corresponding T-shaped grooves.
[0019] Optionally, two support seats are symmetrically installed on the lower surface of the base. The support seats are L-shaped and have four slag discharge ports evenly distributed on their lower surfaces. The four slag discharge ports are respectively connected to four T-shaped sliding grooves.
[0020] Optionally, the pressure head further includes:
[0021] A threaded head is installed at the center of the side of the pressure head facing the positioning rod. The side of the positioning rod facing the pressure head has a threaded hole, and the threaded head is threaded into the threaded hole. The side of the pressure head away from the threaded head has an internal hexagonal hole at the center that mates with an internal hexagonal wrench.
[0022] Optionally, the pressure head has a conical structure, and the diameter of the end of the pressure head near the positioning rod is larger than the diameter of the positioning rod.
[0023] Optionally, a rubber block is provided on the lower side of the pressure plate, and multiple rubber heads are evenly installed on the upper surface of the rubber block. Multiple insertion holes that mate with the rubber heads are opened on the lower surface of the pressure plate. The rubber heads are inserted into the insertion holes and the rubber heads and insertion holes are interference fit.
[0024] Optionally, the rubber head and the rubber block are integrally formed, and the thickness of the end flange and the distance between the rubber block and the base are the same.
[0025] The beneficial effects of this utility model are:
[0026] Screw the threaded end on the pressure head into the threaded hole on the positioning rod to complete the assembly of the pressure head and the positioning rod. At this time, multiple rubber sleeves are confined to the positioning rod. Because the rubber sleeves are deformable, after the structure formed by the positioning rod and the rubber sleeves is inserted into the hole on the end flange, the burrs in the hole on the end flange will deform the rubber sleeves, thus facilitating the insertion of the positioning rod into the hole on the end flange. At the same time, the rubber sleeves protect the positioning rod from being scratched or damaged. The multiple rubber sleeves are in contact end to end, making it easy to replace the damaged rubber sleeves individually. Furthermore, the rubber sleeves rotate around the positioning rod, making it easier for the damaged parts of the rubber sleeves to face the area of the burrs in the hole on the end flange, which helps to improve the service life of the rubber sleeves.

[0042] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0043] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a ball valve processing anti-deviation mechanism, including a ball valve body 2, wherein both ends of the ball valve body 2 are integrally formed with end flanges 22, and the top of the ball valve body 2 is integrally formed with a top flange 21. The base 1 is set on the lower side of the ball valve body 2, and two support seats 10 are symmetrically installed on the lower surface of the base 1. The support seats 10 have an L-shaped structure. The support seats 10 are installed at the required position using screws to complete the restriction of the position of the base 1.
[0044] See Figure 1 , Figure 2 , Figure 4 and Figure 5 Two clamping plates 3 are slidably mounted on the upper surface of the base 1. End flanges 22 are arranged parallel to the clamping plates 3. Screws 31 are rotatably mounted on the opposite sides of both clamping plates 3. Two lugs 32 are symmetrically mounted on the upper surface of the base 1, each with a screw hole 34 on its opposite face, allowing the screws 31 to be threaded into the screw holes 34, thus completing the threaded connection between the screws 31 and the base 1. A handle 33 is mounted on the end of the screw 31 furthest from the clamping plate 3. Two T-shaped sliders 35 are symmetrically mounted on the lower surface of the clamping plates 3. The upper surface of the base 1 is positioned at the ball valve... Both sides of body 2 are machined with two T-shaped grooves 11 that cooperate with T-shaped sliders 35, so that T-shaped sliders 35 can be slidably installed in the corresponding T-shaped grooves 11, improving the stability of the connection between clamping plate 3 and base 1. The lower surface of the support seat 10 is evenly provided with four slag discharge ports 12, which are respectively connected to four T-shaped grooves 11. The debris falling into the T-shaped grooves 11 will be discharged from the slag discharge ports 12 under the push of T-shaped sliders 35. The screw 31 is rotated by the handle 33, thereby changing the relative position of clamping plate 3 and base 1.
[0045] See Figures 1-5Multiple positioning rods 8, which mate with holes on the end flanges 22, are installed on the middle of the upper surface of the base 1 and on the opposite sides of the two clamping plates 3. Multiple rubber sleeves 4, with their ends in contact, are fitted onto the positioning rods 8, allowing the conical pressure head 5 to be threadedly connected to one end of the positioning rod 8. This restricts the relative position of the rubber sleeves 4 and the positioning rods 8. The diameter of the end of the pressure head 5 closest to the positioning rod 8 is larger than the diameter of the positioning rod 8, so that the threaded head 52 is installed at the middle of the side of the pressure head 5 facing the positioning rod 8. Then, a threaded hole 81 is opened on the side of the positioning rod 8 facing the pressure head 5, allowing the threaded head 52 to be threaded into the threaded hole 81, completing the assembly of the pressure head 5 and the positioning rod 8. The pressure head 5 has an internal hexagonal hole 51 at the center of the side facing away from the threaded head 52, which is compatible with an internal hexagonal wrench. This allows the pressure head 5 to be turned with the internal hexagonal wrench, and the screw 31 to drive the clamping plate 3 to move. This allows the positioning rods 8 on the two clamping plates 3 to be inserted into the corresponding holes on the two end flanges 22, thereby clamping and limiting the ball valve body 2. This also facilitates the deburring of the holes on the top flange 21. The multiple positioning rods 8 on the base 1 are inserted into the corresponding holes on one end flange 22. Then, the structure formed by the clamping plate 3 and the pressure plate 6 clamps the lower end flange 22, which facilitates the deburring of the holes on the end flange 22.
[0046] See Figures 1-5 The pressure plate 6 is installed on the lower part of the side of the clamping plate 3 facing the ball valve body 2, so that the pressure plate 6 and the positioning rod 8 on the base 1 cooperate to restrict the position of the end flange 22. A rubber block 7 is provided on the lower side of the pressure plate 6. Multiple rubber heads 71 are evenly installed on the upper surface of the rubber block 7. The rubber heads 71 and the rubber block 7 are integrally formed. Multiple insertion holes 61 that mate with the rubber heads 71 are opened on the lower surface of the pressure plate 6. After the rubber heads 71 are inserted into the insertion holes 61, the rubber heads 71 and the insertion holes 61 are interference-fitted to complete the insertion of the rubber block 7 and the pressure plate 6. The thickness of the end flange 22 is the same as the distance between the rubber block 7 and the base 1. The design of the rubber block 7 makes it easy for the pressure plate 6 to press smoothly onto the end flange 22. The threaded head 52 on the pressure head 5 is screwed into the positioning rod 8. Within the threaded hole 81 on the positioning rod 8, the pressure head 5 and the positioning rod 8 are assembled. At this time, multiple rubber sleeves 4 are confined on the positioning rod 8. Because the rubber sleeves 4 have deformable properties, after the structure formed by the positioning rod 8 and the rubber sleeves 4 is inserted into the hole on the end flange 22, the burrs in the hole on the end flange 22 will deform the rubber sleeves 4, thereby facilitating the insertion of the positioning rod 8 into the hole on the end flange 22. At the same time, under the protection of the rubber sleeves 4, the positioning rod 8 is prevented from being scratched or damaged. Multiple rubber sleeves 4 are in contact end to end, making it easy to replace the damaged rubber sleeves 4 individually. Furthermore, the rubber sleeves 4 rotate around the positioning rod 8, making it easier for the damaged part of the rubber sleeve 4 to face the area of the burrs in the hole on the end flange 22, which is beneficial to improving the service life of the rubber sleeves 4.
