Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing technology, specifically a burr removal device for valve manufacturing. Background Technology

[0002] In modern industry, valves, as an important component of fluid control systems, are widely used in various fields such as petroleum, chemical, power, metallurgy, and urban infrastructure. With the development of industrial technology and the increasing demands for production efficiency and product quality, the requirements for the manufacturing precision and internal structure of valves are becoming increasingly stringent.

[0003] However, during valve manufacturing, especially after casting or machining, irregular burrs or flash often form on the inner wall of the valve. If these burrs are not effectively treated, they will not only directly affect the sealing performance of the valve, but may also increase the resistance of fluid passing through the valve, affecting fluid transmission efficiency. In severe cases, they may even lead to equipment failure or safety accidents. In addition, the presence of burrs will accelerate the wear of internal valve components and shorten the valve's service life. Traditional burr removal methods mainly include manual grinding, chemical solvent corrosion, or mechanical polishing with specific abrasives. However, these methods generally suffer from low efficiency, unstable treatment results, and difficulty in adapting to complex valve inner walls. Furthermore, in some cases, such as when dealing with large valves or valves made of high-hardness materials, the above methods are inadequate and cannot meet the high standards required by modern industrial production.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1-6 As shown, a burr removal device for valve manufacturing includes: a processing table 1, an electric guide rail 11 fixedly installed on the top of the processing table 1, a processing platform 12 fixedly installed on the slide of the electric guide rail 11, and an equipment cabinet 13 provided on the processing table 1; a rotating component, which is located on the processing platform 12 and is used to rotate the valve; and a lifting component, which is located inside the equipment cabinet 13 and is used to adjust the grinding height.

[0028] The equipment cabinet 13 is equipped with a drive motor 14 inside. One end of the drive motor 14 is connected to a grinding head 15. The drive motor 14 is fixedly installed on the top of the moving platform 32. The drive shaft of the drive motor 14 extends to the outside through the moving slot 34. The equipment cabinet 13 is equipped with a control panel.

[0029] When deburring the valve body, the valve body is placed on the processing table 12, and then the processing table 12 is moved by the electric guide rail 11 to the side of the equipment cabinet 13, so that the grinding head 15 is inserted into the inside of the valve body. Then, the grinding head 15 is lowered by the lifting component to fit against the inner wall of the valve body. Then, the drive motor 14 is started to drive the grinding head 15 to rotate. The rotation of the grinding head 15 causes friction with the inner wall of the valve body, thereby removing the burrs on the inner wall of the valve body. After one part is ground, the valve body is rotated by the rotating component to grind away the burrs around the inner wall of the valve body. With the electric guide rail 11 feeding the valve body, the inner wall of the valve body is ground smooth.

[0030] Example 2

[0031] Based on Embodiment 1, the rotating assembly includes: a mounting groove 2, a rotating roller 21, a mounting cavity 22, a reducer 23, a drive gear 24, a tooth groove 25, a through groove 26, and a chain 27. The top of the processing table 12 is provided with a mounting groove 2. Two rotating rollers 21 are rotatably connected between the inner walls of opposite sides of the mounting groove 2. The processing table 12 is provided with a mounting cavity 22. The mounting cavity 22 is provided with a reducer 23. One end of the reducer 23 is driven and connected to the drive gear 24. A tooth groove 25 is provided at the middle position of the two rotating rollers 21. A through groove 26 is provided between the mounting groove 2 and the mounting cavity 22. A chain 27 is connected between the two tooth grooves 25 and the drive gear 24.

[0032] The processing table 12 is fixedly installed with a gantry frame 4. The processing table 12 has two placement slots 41 on its top. The installation cavity 22 has multiple heat dissipation slots a42 on one side. The gantry frame 4 is fixedly installed with a pneumatic rod 43 on its top. The output end of the pneumatic rod 43 extends through the gantry frame 4 to the outside and is fixedly connected to a clamping frame 44. The clamping frame 44 has a pressing groove 45 at its bottom.

[0033] The flanges at both ends of the valve body are placed in the two placement slots 41, and the valve body is placed between the two rotating rollers 21. Then, the pneumatic rod 43 is activated to push the clamping frame 44 downward, so that the pressure groove 45 of the clamping frame 44 presses the valve body down, thereby pressing and fixing the valve body to prevent rotation during grinding. When it is necessary to rotate the valve body, the pneumatic rod 43 is controlled to retract a certain distance, driving the clamping frame 44 to move upward a certain distance to separate it from the valve body. Then, the reducer 23 is activated to drive the drive gear 24 to rotate, and the rotation of the drive gear 24 drives the chain 27 to move. When the chain 27 moves, it drives the two toothed grooves 25 to rotate synchronously. The toothed grooves 25 drive the rotating roller 21 to rotate. The rotating roller 21 has anti-slip texture on the outside to improve friction. When the rotating roller 21 rotates, it drives the valve body to rotate and adjust its state. It works with the grinding head 15 to grind the entire inner wall of the valve body. When the valve body is rotated again, the drive motor 14 will stop working. After the rotation adjustment is completed, it will be fixed. The control pneumatic rod 43 pushes the clamping frame 44 to move downward, so that the pressing groove 45 of the clamping frame 44 presses the valve body. Then the drive motor 14 is turned on to grind.

[0034] Example 3

[0035] Based on Embodiment 1, the lifting assembly includes: a guide plate 3, a base plate 31, a moving platform 32, an electric push rod 33, and a moving groove 34. Two guide plates 3 are fixedly installed on the inner wall of the equipment cabinet 13, and a base plate 31 is fixedly connected between the two guide plates 3. A moving platform 32 is provided on the base plate 31, and an electric push rod 33 is provided below the base plate 31. The top of the electric push rod 33 is connected to the bottom of the moving platform 32. A moving groove 34 is provided on the side of the equipment cabinet 13 near the electric guide rail 11.

[0036] Among them, multiple heat dissipation slots b5 are opened on one side of the equipment cabinet 13, and a limit switch 51 is fixedly installed on the inner wall of the equipment cabinet 13 near the top.

[0037] When the grinding head 15 is raised or lowered, the electric push rod 33 is activated to move the moving table 32 by controlling the ejection or retraction. The moving table 32 moves between the two guide plates 3. The two guide plates 3 guide the moving table 32 so that the moving table 32 drives the drive motor 14 to move smoothly. The drive motor 14 drives the grinding head 15 to move up and down, thereby controlling the degree of grinding. The limit switch 51 and the base plate 31 limit the moving distance of the moving table 32. The heat dissipation groove b5 facilitates the heat dissipation of the drive motor 14.
