Description
Technical Field
[0001] This invention relates to the field of tubular component processing technology, specifically a grinding device for processing tubular components. Background Technology
[0002] A grinding device is a piece of equipment used to smooth the surface of an object. It is a combination of mechanical equipment or tools used to grind, polish or finish the surface of an object. Its core task is to remove the surface layer of the material through physical or chemical means to achieve the transformation from "rough" to "fine". Tubular components are those components with closed or semi-closed cross sections and internal cavities. During the processing of tubular components, grinding devices are used to grind the tubular components to improve their geometric accuracy and assembly assurance.
[0003] The existing technical solution has the following defects: when the grinding device grinds the tubular parts, it uses a fixed clamp to hold and limit the tubular parts. Because the fixed clamp is used to limit the tubular parts, the limiting effect of the tubular parts is poor. Therefore, we propose a grinding device for processing tubular parts in order to solve the problems mentioned above. Summary of the Invention
[0004] The purpose of this invention is to provide a grinding device for processing tubular parts, so as to solve the problem that when the grinding device proposed in the background art grinds tubular parts, the clamping and limiting of the tubular parts by the fixing clamp leads to poor limiting effect of the tubular parts.

A rotating rod is mounted on the upper side of the grinding wheel, and a rotating shaft is installed on the rear side of the rotating rod. A connecting wheel is installed on the rear side of the rotating shaft, and a connecting structure is installed on the outer side of the connecting wheel. The connecting structure includes a connecting belt, a pulley, and a fan blade. The connecting belt is located on the outer side of the connecting wheel, and a pulley is connected to the lower end of the connecting belt. A fan blade is installed on the front side of the pulley.
[0006] Preferably, a hydraulic cylinder is fixedly installed inside the middle side of the base plate, and a fixing plate is connected to the lower inside of the base plate. An mounting plate is installed on the upper side of the hydraulic cylinder, and a limit plate is fixedly installed on the upper middle side of the mounting plate.
[0007] Preferably, a fixing block is also fixedly installed on the upper right side of the mounting plate, and a second motor is fixedly installed on the middle right side of the fixing block.
[0008] Preferably, a connecting plate is fixedly installed on the upper left side of the mounting plate, and a third motor is fixedly installed on the upper left side of the connecting plate. A mounting rod is installed on the output end of the third motor, and a movable rod is connected to the right side of the mounting rod. A connecting rod is installed on the right side of the movable rod, and a mounting block is installed on the right side of the connecting rod.
[0009] Preferably, an electric telescopic rod is fixedly installed on the inner right side of the bracket, and a fixed rod is fixedly installed on the inner rear side of the bracket. A movable plate is installed on the left side of the electric telescopic rod, and a connecting plate is fixedly installed on the rear side of the movable plate. A first motor is fixedly installed on the inner middle side of the movable plate, and the output end of the first motor is connected to the rotating rod.
[0010] Preferably, the rotating rod and the rotating shaft are meshed, and the rotating shaft and the connecting plate are rotatably connected, and a tapered structure is provided on the lower inner side of the connecting plate.
[0011] Preferably, the adjusting rod and the connecting block are connected by a threaded transmission, and the vertical cross-section of the connecting block is a cross-shaped structure.
[0012] Preferably, the support block and the rotating block are connected by a telescopic sliding connection, and the outer side of the support block is provided with a protrusion structure.
[0013] Preferably, the mounting rod and the movable rod form a worm gear structure, and the movable rod and the connecting rod are rotatably connected.
[0014] Preferably, a movable block is also fixedly installed on the right side of the mounting block, and a movable block is connected to the inner middle side of the movable block. The right side of the movable block and the output end of the second motor are both connected to the rotating block.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects: the grinding device for processing tubular parts is provided with a movable structure that can move the airbag, thereby limiting the tubular parts of different sizes, and is provided with a connecting structure that can rotate the fan blade, thereby blowing away the debris generated during grinding. 1. By rotating the adjusting rod, the adjusting rod rotates inside the rotating block, causing the connecting block, which is threadedly connected to the adjusting rod, to slide outward inside the rotating block. This causes the connecting block to push the support block to slide outward, which in turn causes the support block to compress the spring, thereby causing the support block to push the airbag to slide outward. This facilitates the limiting of tubular components of different sizes. 2. By placing the tubular component outside the fixed block, the third motor is started, causing the mounting rod to rotate inside the connecting plate. This causes the movable rod, which forms a worm gear structure with the mounting rod, to rotate on the right side inside the connecting plate. Consequently, the connecting rod, which is rotatably connected to the movable rod, rotates, causing the mounting block, which is rotatably connected to the connecting rod, to slide to the right. This causes the mounting block to drive the moving block to slide to the right on the upper outer side of the limiting plate. The moving block then moves to the left side of the tubular component, where the moving block and the fixed block limit the tubular component. An external air pump then inflates the airbag, causing it to expand and adhere to the inner wall of the tubular component, facilitating the limiting of the tubular component. 3. By starting the first motor, the first motor drives the rotating rod to rotate inside the moving plate, thereby causing the rotating rod to drive the grinding wheel to grind the tubular parts. The rotation between the rotating rod and the moving plate causes the rotating shaft connected to the rotating rod to rotate inside the rear side of the moving plate. This rotating shaft drives the connecting wheel to rotate inside the upper side of the connecting plate, which in turn drives the connecting belt to move. The connecting belt drives the pulley to rotate inside the lower side of the connecting plate, which in turn drives the fan blade to rotate inside the connecting plate. This fan blade rotation generates wind power. When the wind power passes through the conical structure opened on the lower side of the connecting plate, the air is forced to pass through an outlet with a smaller area than the fan blade, and the air velocity is significantly increased. This allows the air to blow away the debris generated during grinding, making it convenient to blow away the debris while grinding. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0019] Please see Figures 1-9 The present invention provides the following technical solution: A grinding device for processing tubular parts includes: a base plate 1, a hydraulic cylinder 2, a fixed plate 3, a mounting plate 4, a fixed block 5, a bracket 6, a movable plate 7, a first motor 8, a rotating rod 9, a grinding wheel 10, a connecting plate 11, a second motor 12, a rotating block 13, an adjusting rod 14, a connecting block 15, a spring 16, a support block 17, an airbag 18, a limiting plate 19, a connecting plate 20, a third motor 21, a mounting rod 22, a movable rod 23, a connecting rod 24, a mounting block 25, a movable block 26, a movable block 27, a fixed rod 28, a rotating shaft 29, a connecting wheel 30, a connecting belt 31, a pulley 32, a fan blade 33, and an electric telescopic rod 34. When using it for work, specifically such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, an adjusting rod 14 is movably installed inside the center of the rotating block 13, a connecting block 15 is movably installed outside the adjusting rod 14, a spring 16 is fixedly installed inside the rotating block 13, a support block 17 is fixedly installed inside the spring 16, and an airbag 18 is fixedly installed outside the support block 17. Manually turning the adjusting rod 14 causes it to rotate inside the center of the rotating block 13. This rotation between the adjusting rod 14 and the rotating block 13 causes the adjusting rod 14 to move within the center of the connecting block 15. The threaded connection allows the connecting block 15 to slide outward from inside the rotating block 13 under the action of the thread between the adjusting rod 14 and the connecting block 15. This sliding action between the connecting block 15 and the rotating block 13 causes the cross-shaped connecting block 15 to push the support block 17 to slide outward. As a result, the support block 17 drives the spring 16 to compress under the action of sliding outward, which in turn causes the support block 17 to drive the airbag 18 to slide outward, making it convenient to limit the movement of tubular components of different sizes. Specific examples Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, a limiting plate 19 is fixedly installed on the middle side of the upper end of the mounting plate 4, a connecting plate 20 is fixedly installed on the left side of the upper end of the mounting plate 4, a third motor 21 is fixedly installed on the left side of the upper end of the connecting plate 20, a mounting rod 22 is installed at the output end of the third motor 21, a movable rod 23 is connected to the right side of the mounting rod 22, a connecting rod 24 is installed to the right side of the movable rod 23, a mounting block 25 is installed to the right side of the connecting rod 24, and a movable block 26 is fixedly installed to the right side of the mounting block 25. The tubular component is manually placed outside the fixed block 5, and the controller starts the third motor 21, causing the third motor 21 to drive the mounting rod 22 to rotate inside the connecting plate 20. Thus, the rotation between the third motor 21 and the mounting rod 22 causes the mounting rod 22 to... The movable rods 23 are connected by a worm gear, which causes the movable rods 23 to rotate on the right side inside the connecting plate 20. Under the rotation between the movable rods 23 and the connecting plate 20, the movable rods 23 drive the connecting rods 24 to rotate, which causes the mounting block 25, which is rotatably connected to the connecting rods 24, to slide to the right. This causes the mounting block 25 to drive the moving block 26 to slide to the right on the outer side of the upper end of the limiting plate 19, so that the moving block 26 moves to the left side of the tubular component. This allows the moving block 26 and the fixed block 5 to limit the tubular component. Then, an external air pump inflates the airbag 18, causing the airbag 18 to expand and fit against the inner wall of the tubular component, facilitating the limitation of the tubular component. Specific examples Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, a hydraulic cylinder 2 is fixedly mounted inside the middle of the base plate 1 via a controller located on the right side of the base plate 1. A fixed plate 3 is fixedly installed on the lower side of the base plate 1. An mounting plate 4 is fixedly installed on the upper side of the hydraulic cylinder 2. A fixed block 5 is fixedly installed on the upper right side of the mounting plate 4. A second motor 12 is located on the right side of the fixed block 5. A movable block 27 is movably installed inside the middle of the movable block 26. Rotating blocks 13 are installed on the right side of the movable block 27 and at the output end of the second motor 12. The controller controls the start of the hydraulic cylinder 2, so that the hydraulic cylinder 2 drives the mounting plate 4 on the base plate 1. The mounting plate 4 slides upward inside the fixed plate 3, thereby causing the mounting plate 4 to move the tubular component to fit against the grinding wheel 10. The controller controls the start of the second motor 12, which drives the rotating block 13 to rotate in the middle of the fixed block 5. This causes the rotating block 13 to rotate the tubular component, which in turn causes the moving block 27 to rotate inside the moving block 26 via the rotating block 13, enabling the different surfaces of the tubular component to be ground. Then, a bracket 6 is fixedly installed on the upper rear side of the base plate 1. An electric telescopic rod 34 is fixedly installed on the right side inside the bracket 6. A fixed rod 28 is fixedly installed on the rear side inside the bracket 6. A movable plate 7 is fixedly installed on the left side of the electric telescopic rod 34. A first motor 8 is fixedly installed on the upper side inside the movable plate 7. A rotating rod 9 is installed at the output end of the first motor 8. A grinding wheel 10 is fixedly installed on the lower side of the rotating rod 9. The controller controls the start of the first motor 8, so that the first motor 8 drives the rotating rod 9 to rotate inside the movable plate 7, thereby causing the rotating rod 9 to drive the grinding wheel 10 to grind the tubular parts. The connecting plate 11 is fixedly installed on the lower rear side of the movable plate 7. A rotating shaft 29 is installed on the middle rear side of the rotating rod 9. A connecting wheel 30 is fixedly installed on the rear side of the rotating shaft 29. A connecting belt 31 is set on the outer side of the connecting wheel 30. A pulley 32 is installed on the inner side of the lower end of the connecting belt 31. A fan blade 33 is fixedly installed on the front side of the pulley 32. Under the rotation between the rotating rod 9 and the movable plate 7, the rotating shaft 29, which is meshed with the rotating rod 9, rotates on the rear side inside the movable plate 7. This causes the rotating shaft 29 to drive the connecting wheel 30 to rotate on the upper side inside the connecting plate 11. Then, under the rotation of the connecting wheel 30, the connecting wheel 30 drives the connecting belt 31 to move. This causes the connecting belt 31 to drive the pulley 32 to rotate on the lower side inside the connecting plate 11. The pulley 32 drives the fan blade 33 to rotate inside the connecting plate 11, which in turn generates wind. The wind passes through the conical structure on the lower side of the connecting plate 11, forcing the air to pass through an outlet with a smaller area than the fan blade 33, which significantly increases the air velocity. This allows the air to blow away the debris generated during grinding, making it convenient to blow away debris while grinding. The controller activates the electric telescopic rod 34, which drives the moving plate 7 to slide inside the upper side of the bracket 6. This causes the moving plate 7 to slide outside the fixed rod 28, which in turn moves the grinding wheel 10, improving the grinding effect on tubular parts.
