Description

Technical Field

[0001] This invention relates to a grinding device, specifically a fan impeller grinding device with a self-priming dust collection function, belonging to the technical field of grinding devices. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas; it is a type of driven fluid machinery. After the fan impeller is cast, it will have burrs and flash, requiring polishing to obtain a sufficiently smooth surface before it can be put into use.

[0003] Traditional polishing equipment mostly involves workers using hand-held polishing tools to polish and grind the impeller, removing burrs and flash. This method is not only inefficient but also difficult to control in terms of precision. Generally, a brush is used to clean the metal shavings after polishing. Although this achieves the purpose of cleaning, the metal shavings and dust generated during the polishing process can easily spread everywhere, causing harm to people and the environment. Therefore, some factories use protective covers to prevent waste from flying when polishing blades.

[0004] However, existing protective covers are all transparent baffles that block waste chips. However, this kind of protection can only prevent waste chips from splashing outwards onto the operator, but it cannot reduce the accumulation of waste chips on the workbench. The impeller blades are arranged in a vortex-like ring, and ordinary baffles are not effective enough in blocking waste chips. Waste chips splashed on other blades will affect the grinding of other blades, easily causing scratches on the blades and affecting product quality. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this invention is to provide a fan impeller grinding device with self-collecting dust function to solve the above-mentioned problems. In order to solve the problem that in the prior art, the impeller blades are arranged in a vortex-shaped ring, and the ordinary baffle is not effective in blocking waste. Waste splashes on other blades will affect the grinding of other blades, easily causing scratches on the blades and affecting product quality.

The gear meshes with the arc-shaped rack. The first motor starts and drives the gear to rotate, which in turn drives the arc-shaped rack to rotate, thereby causing the fixing ring to rotate.

[0017] Preferably, a first slide rail is fixedly connected to both sides of the top of the machine body, and a second slide rail is provided between the two first slide rails. The two ends of the second slide rail are fixedly connected to the moving ends of the two first slide rails respectively.

[0018] Preferably, the grinding assembly includes a second motor, a third motor, a rotating shaft, and a grinding wheel. A support disc is fixedly connected to the outer side of the rotating shaft. The second motor is fixedly connected to the bottom end of the electric cylinder. Movable brackets are fixedly connected to both sides of the second motor. A second bracket is provided between the two movable brackets. A first connecting rod is fixedly connected to both sides of the second bracket.

The two second connecting rods are fixedly connected to both sides of the inner wall of the second bracket respectively, supporting and limiting the third motor, allowing the third motor to deflect around the second connecting rods.

[0019] Preferably, a rotating plate is fixedly connected to the output end of the second motor, a movable plate is provided on one side of the rotating plate, an electric push rod is fixedly connected inside the rotating plate, the output end of the electric push rod is fixedly connected to the movable plate, and sliding rods are fixedly connected to both sides inside the rotating plate.

A connecting plate is fixedly connected to the bottom of the movable plate, and a hinge rod is rotatably connected to the bottom of the connecting plate. The hinge rod is hinged to the top of the third motor, so that the electric push rod can start and drive the movable plate to extend and retract, thereby driving the connecting plate and the hinge rod to move and adjust the tilt angle of the third motor.

[0020] This invention provides a fan impeller grinding device with a self-priming dust collection function, which has the following beneficial effects:

[0021] This fan impeller grinding equipment with self-priming dust collection function uses a fixed ring to drive multiple tie rods to move, which in turn push multiple connecting blocks to move. These connecting blocks are fixedly connected to multiple push blocks, thus moving the push blocks and causing them to move multiple arc-shaped support plates. Because one corner of each arc-shaped support plate is rotatably connected to a support rod, the support plate is limited, causing it to deflect around the support rod. As the arc-shaped support plates rotate, they drive the push blocks and connecting blocks to rotate. When the connecting blocks move, they... The movement of the casings causes multiple casings to retract inwards and deflect around multiple support rods, aligning the multiple casings with the multiple blades of the impeller. The impeller blades also deflect around the central axis, so that the multiple casings are fitted onto the outside of the multiple blades during movement. In addition, because the blades have a certain tilt angle, the angle of the impeller is adjusted by bolts to adjust the angle of the casings, so that the angle of the casings is consistent with the tilt angle of the blades. After the multiple casings are fitted onto the multiple blades, they protect the blades and can also block and collect the grinding debris generated during the grinding of the blades, preventing it from splashing.

[0022] This fan impeller grinding device with self-priming dust collection function uses a third motor to drive the rotating shaft and grinding wheel into the housing. The grinding wheel is located inside the housing and fits against the blades. At the same time, the rotating shaft passes through the through groove and slides along the through groove. The third motor starts and drives the rotating shaft and grinding wheel to rotate, so that the grinding wheel grinds the blades. The rotating shaft drives the grinding wheel to move inside the housing. When the grinding wheel grinds the blades, the rotating shaft slides inside the through groove. Because mounting plates are fixedly connected to both sides of the top of the housing, and one side of the mounting plate is equipped with bristles, the bristles pass through multiple bristles when the rotating shaft moves. The multiple bristles block the grinding generated during grinding and prevent the grinding particles from passing through the through groove.

[0023] This fan impeller grinding equipment with self-priming dust collection function is activated by a second motor, which drives a rotating plate to rotate. The rotating plate then drives a moving plate, which in turn drives a connecting plate and a hinge rod to rotate. This, in turn, drives a third motor to rotate. When the third motor deflects, it drives a second connecting rod to rotate inside a second bracket, while the first connecting rod rotates inside a moving bracket. The moving bracket and the second bracket support the third motor, allowing for adjustment of its angle to accommodate different blade orientations during grinding. An electric push rod activates the moving plate, which in turn moves the connecting plate and the hinge rod. This causes the hinge rod to tilt the third motor, allowing for adjustment of its tilt angle to accommodate different blade orientations. Attached Figure Description

[0039] This invention provides a fan impeller grinding device with a self-priming dust collection function.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14The system includes a body 1, inside which is a cradle assembly. A fixing plate 6 is mounted on top of the cradle assembly. The cradle assembly includes two supports 2, two rocker arms 3, and a base plate 4. The two supports 2 are fixedly connected to both sides of the body 1. The two rocker arms 3 are rotatably connected to opposite sides of the two supports 2. A motor output shaft is located inside each support 2 and connected to the rocker arms 3, allowing the rocker arms 3 to rotate. The base plate 4 is fixedly connected between the two rocker arms 3. A platform 5 is fixedly connected to the top of the base plate 4. The fixing plate 6 is mounted on top of the platform 5 for easy fixation. A three-jaw chuck 24 is fixedly connected to the top of the fixing plate 6. The three-jaw chuck 24 and its corresponding control system can be purchased components. The clamping action should meet the standard. A collar 7 is provided on the top of the fixed plate 6. Multiple support rods 8 are fixedly connected to the top of the fixed plate 6 in a circular array. All support rods 8 pass through the collar 7 and are fixedly connected to the collar 7. Arc-shaped support plates 9 are rotatably connected to the outside of the multiple support rods 8. Push blocks 13 are fixedly connected to the top of the rear side of the multiple arc-shaped support plates 9. A housing 15 is provided on the top of the multiple push blocks 13. A grinding component is provided at the top of the inside of the machine body 1. The grinding component is used to adapt to the real-time angle required for grinding while meeting the requirements of multi-angle adjustment. It needs to be implemented by intelligent PLC control (the PLC control system is not considered as an improvement discussed in this application, and there are many existing technologies that can be adopted).

[0041] Both sides of the top of the body 1 are fixedly connected to a first slide rail 25. A second slide rail 26 is arranged between the two first slide rails 25. The two ends of the second slide rail 26 are fixedly connected to the moving ends of the two first slide rails 25 respectively. A moving seat 27 is slidably connected to the moving end inside the second slide rail 26. The moving seat 27 has the characteristic of lateral sliding, which allows the structure suspended at the bottom to move laterally with it (to... Figure 2 (View Perspective) An electric cylinder 28 is fixedly connected to the bottom of the movable base 27. The grinding assembly includes a second motor 29, a third motor 33, a rotating shaft 35, and a grinding wheel 36. A support disc 52 is fixedly connected to the outer side of the rotating shaft 35. The second motor 29 is fixedly connected to the bottom of the electric cylinder 28. Movable brackets 30 are fixedly connected to both sides of the second motor 29. A second bracket 31 is provided between the two movable brackets 30. First connecting rods 32 are fixedly connected to both sides of the second bracket 31. The two first connecting rods 32 are rotatably connected to the two movable brackets 30 respectively, so that... The second bracket 31 can deflect around the first connecting rod 32. The third motor 33 is located inside the second bracket 31. The third motor 33 has two second connecting rods 34 fixedly connected to both sides. The two second connecting rods 34 are respectively fixedly connected to the inner walls of the second bracket 31, supporting and limiting the third motor 33, allowing it to deflect around the second connecting rods 34. A rotating plate 37 is fixedly connected to the output end of the second motor 29. A movable plate 38 is provided on one side of the rotating plate 37. An electric push rod 39 is fixedly connected inside the rotating plate 37.

[0042] The output end of the push rod 39 is fixedly connected to the moving plate 38. Slide rods 40 are fixedly connected to both sides inside the rotating plate 37. The two slide rods 40 pass through the moving plate 38 and are slidably connected to the moving plate 38. A connecting plate 41 is fixedly connected to the bottom of the moving plate 38. A hinge rod 42 is rotatably connected to the bottom of the connecting plate 41. The hinge rod 42 is hinged to the top of the third motor 33, so that the electric push rod 39 is started to drive the moving plate 38 to extend and retract, thereby driving the connecting plate 41 and the hinge rod 42 to move and adjust the tilt angle of the third motor 33. The electric push rod is also called an electric cylinder, electric telescopic rod, bamboo joint telescopic rod, etc.

[0043] Multiple limiting blocks 10 are fixedly connected in a circular array on the outer side of the fixed plate 6. A fixing ring 11 is provided on the top of the fixed plate 6. The fixing ring 11 is slidably connected to the inside of the multiple limiting blocks 10 to support the fixing ring 11. Multiple pull rods 12 are hinged in a circular array on the top of the fixing ring 11. Connecting blocks 14 are fixedly connected to one side of each of the multiple push blocks 13. The ends of the multiple pull rods 12 away from the fixing ring 11 are respectively hinged to the multiple connecting blocks 14. The arc-shaped support plate 9 is limited by the pull rods 12. The arc-shaped support plate 9 is actually a semi-elliptical structure with an arc-shaped concave area. The design provides a good external transition when in contact with other components. When the fixed ring 11 rotates, it drives the pull rod 12 to move, thereby driving the connecting block 14 and the push block 13 to move. One of the limiting blocks 10 is fixedly connected to a first motor 21 on one side. The output end of the first motor 21 is fixedly connected to a gear 22. An arc-shaped rack 23 is fixedly connected to one side of the fixed ring 11. The gear 22 and the arc-shaped rack 23 are meshed and connected. The first motor 21 starts and drives the gear 22 to rotate, which in turn drives the arc-shaped rack 23 to rotate, thereby driving the fixed ring 11 to rotate.

[0044] The push block 13 is thicker than the arc-shaped support plate 9 and has a certain weight. When the push block 13 moves with the arc-shaped support plate 9, it has better stability. Each of the multiple push blocks 13 is fixedly connected to a fixed shaft 44 on one side. Multiple sleeves 15 are rotatably connected to the top of multiple vertical plates 45. Each of the multiple sleeves 15 has a through groove on its top. Each of the multiple sleeves 15 has a mounting plate 16 fixedly connected to both sides of its top. Two mounting plates 16 are respectively set on both sides of the through groove. Brush bristles 17 are fixedly connected to the opposite side of each of the two mounting plates 16. Two brush bristles 17 are staggered and fit into the through groove, blocking it and preventing the grinding material collected inside the housing 15 from splashing out. (Additionally, depending on actual usage needs, the brush bristles 17 can be replaced with existing snap-fit ​​modular brush bodies with corresponding snap-fit ​​interfaces for quick replacement after wear. The snap-fit ​​type can be a groove that snaps into the edge and is tightened with a fastening screw or a spring-loaded snap-fit ​​structure. This is only a partial expansion and will not be elaborated further.) Multiple housings 15 have... Multiple connecting pipes 18 are fixedly connected, with one end of each connecting pipe 18 extending into the interior of multiple housings 15. The other end of each housing 15 passes through multiple vertical plates 45 and is rotatably connected to the vertical plates 45, providing fixed support for the housings 15 and connecting them to the vertical plates 45. Each connecting pipe 18 has a fixedly connected wheel 20 on its outer side, and each wheel 20 is fixedly connected to the vertical plate 45 by bolts. This allows for easy adjustment of the angle between the connecting pipes 18 and the housings 15 via the wheels 20, and also enables the wheels 20 to be positioned by the bolts. The casing 15 has transparent side arc plates 46 on both sides. A center plate 50 is fixedly connected to the bottom of the casing 15. Limiting plates 49 are fixedly connected to both sides of the center plate 50. A multi-stage telescopic plate 47 is fixedly connected between the casing 15 and the two transparent side arc plates 46. A sliding plate 48 is fixedly connected to one side of the bottom of the two transparent side arc plates 46. The two sliding plates 48 are slidably connected to the inside of the two limiting plates 49. Springs 51 are provided inside the two limiting plates 49. The two ends of the springs 51 are in contact with the sliding plate 48 and the limiting plate 49, respectively.

[0045] Specifically, the impeller is first placed on top of the fixed plate 6. The impeller is rotated to align its blades with the positions of the multiple housings 15. The three-jaw chuck 24 is then activated to clamp and fix the central shaft of the impeller. Once the impeller is fixed, the first motor 21 is activated, driving the gear 22 to rotate. When the gear 22 rotates, it drives the arc-shaped rack 23 to rotate, causing the arc-shaped rack 23 to drive the fixed ring 11 to rotate. The fixed ring 11 then drives multiple pull rods 12 to move, thereby pushing multiple connecting blocks 14 to move. The multiple connecting blocks 14 are fixedly connected to multiple push blocks 13, thus driving the multiple push blocks 13 to move. The multiple push blocks 13 then drive the multiple arc-shaped support plates 9 to move. Since one corner of the arc-shaped support plate 9 is rotatably connected to the support rod 8, the arc-shaped support plate 9 is limited, thus… Multiple arc-shaped support plates 9 are deflected around the support rod 8 as the center. When the multiple arc-shaped support plates 9 rotate, they drive the push block 13 and the connecting block 14 to rotate. When the connecting block 14 moves, it drives the sleeve 15 to move, causing the multiple sleeves 15 to retract inward and deflect around the multiple support rods 8. This makes the multiple sleeves 15 correspond to the multiple blades of the impeller. The impeller blades also deflect around the central axis, so that the multiple sleeves 15 are fitted onto the outside of the multiple blades when they move. In addition, because the blades have a certain tilt angle, the angle of the rotating wheel 20 is adjusted by bolts to adjust the angle of the sleeves 15 so that the angle of the sleeves 15 is consistent with the tilt angle of the blades. After the multiple sleeves 15 are fitted onto the multiple blades, they protect the blades and can also block and collect the grinding generated by the blades during grinding to prevent splashing.

[0046] The first slide rail 25 is activated, driving the second slide rail 26 to move. The second slide rail 26 then moves the moving seat 27, adjusting the position of the third motor 33 for grinding. The electric cylinder 28 is activated, driving the second motor 29 to descend, which in turn drives the third motor 33 to descend for grinding. The third motor 33 moves to one side of one of the housings 15, causing it to drive the rotating shaft 35 and grinding wheel 36 into the housing 15. The grinding wheel 36 is positioned inside the housing 15, fitting against the blades. Simultaneously, the rotating shaft 35 passes through the through groove and moves along... The grinding wheel 36 rotates along the through groove, driven by the third motor 33. This causes the grinding wheel 36 to grind the blades. The rotating shaft 35 moves the grinding wheel 36 inside the housing 15. While the grinding wheel 36 is grinding the blades, the rotating shaft 35 slides inside the through groove. Since mounting plates 16 are fixedly connected to both sides of the top of the housing 15, and bristles 17 are provided on one side of the mounting plates 16, the bristles 17 pass through the multiple bristles 17 when the rotating shaft 35 moves. The multiple bristles 17 block the grinding generated during grinding, preventing the grinding particles from passing through the through groove.

[0047] The second motor 29 starts and drives the rotating plate 37 to rotate. The rotation of the rotating plate 37 drives the moving plate 38 to rotate, which in turn drives the connecting plate 41 and the hinge rod 42 to rotate, thereby driving the third motor 33 to rotate. When the third motor 33 deflects, it drives the second connecting rod 34 to rotate inside the second bracket 31, and the first connecting rod 32 to rotate inside the moving bracket 30. The moving bracket 30 and the second bracket 31 support the third motor 33, thereby adjusting the angle of the third motor 33 to adapt to the direction of the blade for grinding. The electric push rod 39 starts and drives the moving plate 38 to move, which in turn drives the connecting plate 41 and the hinge rod 42 to move. The hinge rod 42 drives the third motor 33 to tilt, thereby adjusting the tilt angle of the third motor 33 to adapt to the tilt angle of different blades for easy adjustment.

[0048] After the blade enters the housing 15, if the blade width is large, the middle section of the blade pushes the two transparent side arc plates 46 to move to both sides after the blade tip enters the housing 15. This causes the transparent side arc plates 46 to stretch the two multi-stage telescopic plates 47. Simultaneously, the transparent side arc plates 46 move the sliding plate 48, compressing the spring 51 and allowing the sliding plate 48 to slide inside the limiting plate 49. This facilitates the opening of the two transparent side arc plates 46 to accommodate the blade width, ensuring a close fit between the housing 15 and the blade, enhancing the protective effect. Meanwhile, the rotating shaft 3... A support disc 52 is installed on the outer side, with the size of the support disc 52 being slightly larger than that of the grinding wheel 36. When grinding, the support disc 52 extends into the housing 15 and pushes the transparent side arc plate 46 to both sides, so that the grinding wheel 36 will not come into contact with the transparent side arc plate 46. Furthermore, the diameter of the grinding wheel 36 is larger than the widest part of the blade. When grinding the blade, the waste chips will not fly outward, but will be concentrated inside the housing 15 and will not easily leak out due to the cooperation of the bristles 17. This setting eliminates the need for manual cleaning, reduces workload, lowers the possibility of machine operation hazards, and improves processing quality.
