Description

[0002] As a lightweight and high-strength manufacturing material, aluminum rods have been widely used in many fields such as transportation, construction, and aviation. In these fields, the surface quality and dimensional accuracy of aluminum rods have an important impact on the performance and service life of the products. Through grinding, defects and burrs on the surface of aluminum rods can be removed, and their surface finish and dimensional accuracy can be improved to meet various application requirements.

[0003] In order to improve the heat dissipation effect, the existing grinding wheel has a heat dissipation groove on the outer surface of the grinding wheel. However, in the process of grinding the aluminum rod, a lot of dust and aluminum chips are easily accumulated on the outer surface of the grinding wheel and inside the heat dissipation groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The positioning frame is driven to slide by the cylinder, and the positioning frame drives the positioning shaft to move during the sliding process, so that the grinding wheel on the outer side of the positioning shaft moves away from the rubber wheel. During the movement, the inclined sliding block is resisted by the inclined sliding plate and slides away from the inclined sliding plate. During the sliding process of the inclined sliding block, the mounting block is driven to slide. The sliding of the mounting block makes the arc positioning plate 1 no longer resist the inner wall of the positioning groove 1, so that the elastic restoring force of the spring 1 pushes the arc positioning plate 2 to resist the inner wall of the positioning groove 2. When the speed of the grinding wheel is accelerated, it is affected by the eccentric effect of the eccentric block, and the grinding wheel will vibrate, so that the dust on the outer surface of the grinding wheel and the inside of the heat dissipation groove falls off;

[0016] 2. Use the vacuum pump to suck air into the vacuum cylinder, and then use the vacuum pipe to suck air to the grinding position of the grinding wheel, so that the dust generated by grinding is sucked into the filter box, and then filtered through the baffle plate and input into the exhaust pipe. When the grinding wheel slides, the vacuum cylinder slides with it, and absorbs the dust generated by the vibration of the grinding wheel, so as to prevent the dust generated by the grinding of the aluminum rod from flying;

[0017] 3. The torsion spring shaft drives the arc scraper to contact the outer wall of the grinding wheel, so that the large dust attached to the outer surface can be scraped off when the grinding wheel rotates and grinds. After that, when the grinding wheel rotates, the trapezoidal baffle is inserted into the heat dissipation slot and then pushed out, so that the row plate is constantly bumped and hits the outer wall of the grinding wheel, thereby promoting the dust on the outer surface of the grinding wheel and the inside of the heat dissipation slot to fall off. Then, the shaking generated by the grinding wheel hits the trapezoidal baffle, so that the air hole transmits the air from the vacuum pump to the exhaust pipe to eject, which promotes the cleaning of the dust on the surface of the grinding wheel. At the same time, through the angle between the row plate and the grinding wheel, the blown dust will be pushed to diffuse from the angle to flow in the direction of the intake pipe, which promotes the absorption of dust by the intake pipe.

The outer walls of the positioning shafts 7 and the connecting rods 9 are jointly sleeved with a grinding wheel 10, and a plurality of heat dissipation grooves 35 are opened on the outer wall of the grinding wheel 10. An eccentric block 21 is fixedly installed at the center of the inner wall of the grinding wheel 10, and the eccentric block 21 does not contact the connecting rod 9. A driven ring 20 is fixedly installed at one end of the grinding wheel 10. The grinding wheel 10 A positioning ring 201 is fixedly installed at one end away from the driven ring 20, and the driven ring 20 and the positioning ring 201 are both rotatably connected to one side of the positioning frame 6 at the corresponding position. The outer wall of each mounting block 8 is provided with four bevel grooves 11 at equal intervals along the center of the positioning shaft 7, and the inner wall of each bevel groove 11 is slidably connected with a bevel block 12, and each bevel block 12 is fixedly installed with an arc positioning plate 13 at one end away from the mounting block 8, and a positioning groove 14 is provided on the inner wall of the grinding wheel 10, and the positioning groove 14 slides with the arc positioning plate 13. The outer wall of the mounting block 8 is also provided with four slide grooves 15 at equal intervals along the center of the positioning shaft 7, and the slide groove 15 is located on the side close to the driven ring 20, and a slider 16 is slidably connected in the cavity of the slide groove 15, and a spring 17 is fixedly installed on the end of the slider 16 away from the mounting block 8, and a circular arc positioning plate 2 18 is fixedly installed on the end of the spring 17 away from the slider 16, and a positioning groove 2 19 is provided on the inner wall of the grinding wheel 10, and the positioning groove 2 19 is slidably connected with the circular arc positioning plate 2 18, and a flapping structure is provided on one side of the connecting rod 9, wherein the reference Figure 6 The support plate 1 is L-shaped with an inclined upper end, and the rubber wheel 2 is rotatably connected to one side of the inclined surface. At the same time, the rubber wheel 2 can rotate, and the aluminum rod 47 is driven to rotate by the rotation of the rubber wheel 2. At the same time, the rotation speed of the rubber wheel 2 is always slower than the rotation speed of the grinding wheel 10.

[0031] Among them, an inclined sliding block 22 is fixedly installed on one end of the positioning shaft 7 close to the driven ring 20, and an inclined sliding block 23 is slidably connected to the outer wall of the inclined sliding block 22. The inclined sliding block 22 is embedded in the cavity of the inclined sliding block 23, and the contact surface between the inclined sliding block 22 and the inclined sliding block 23 is provided with a beveled edge, and the lower end of the inclined sliding block 23 is fixedly connected to the outer wall of the support plate 1, and a reset cylinder 44 is fixedly installed on the positioning frame 6 close to the side of the positioning ring 201, and the reset cylinder 44 is slidably connected to one end of the positioning shaft 7, and a spring three 45 is fixedly installed inside the reset cylinder 44, and the spring three 45 and the side surface of the positioning shaft 7 are in conflict with each other.

[0032] Specifically, the driven ring 20 and the positioning ring 201 are limited by two positioning frames 6, so that the grinding wheel 10 between the driven ring 20 and the positioning ring 201 cannot slide to both sides. When the cylinder 4 pushes the L-shaped connecting plate 5 to move in the direction away from the roller 3, it will drive the grinding wheel 10 and the positioning shaft 7 to move together. During the movement of the positioning shaft 7, the inclined sliding block 22 will conflict with the inclined edge in the cavity of the inclined sliding plate 23, and the positioning shaft 7 will be driven to slide in the direction away from the inclined sliding plate 23 through the conflict of the inclined edges. During the sliding process of the positioning shaft 7, the mounting block 8 is driven to move.

[0033] Furthermore, when the grinding wheel 10 performs rotational grinding on the aluminum rod 47, the grinding wheel 10 rotates on the outer side wall of the arc positioning plate 13, and the inner side wall of the grinding wheel 10 does not contact the positioning shaft 7, the mounting block 8 and the connecting rod 9. Both ends of the connecting rod 9 are connected to a mounting block 8. The positions of the bevel grooves 11 and the slide grooves 15 provided on the two mounting blocks 8 are both toward the driven ring 20. When the positioning shaft 7 is pushed to slide away from the driven ring 20, the bevel blocks 12 and the slide blocks 16 on the two mounting blocks 8 will slide in the corresponding grooves. The positioning groove 14 and the positioning groove 2 19 are used to limit the corresponding arc positioning plate 13 and the arc positioning plate 2 18. While sliding, the arc positioning plate 13 is contracted toward the mounting block 8 through the upper beveled edge of the beveled groove 11, so that the arc positioning plate 13 no longer limits the grinding wheel 10. At this time, the grinding wheel 10 is limited by the spring 17 pushing the arc positioning plate 2 18 to contact the inner wall of the positioning groove 2 19. The contact of the arc positioning plate 2 18 with the grinding wheel 10 is a soft connection. At this time, when the grinding wheel 10 rotates rapidly, it is affected by the eccentric block 21 installed on the inner wall of the grinding wheel 10, resulting in an unstable center of gravity of the grinding wheel 10, so that the grinding wheel 10 begins to shake, and the dust on the outer surface of the grinding wheel 10 and the inside of the heat dissipation groove 35 are shaken off through the high-frequency shaking of the grinding wheel 10.

[0034] Among them, a filter box 24 is fixedly installed on the upper end of the support plate 1, a baffle 46 is fixedly installed in the cavity of the filter box 24, a telescopic tube 25 is fixedly installed on the end of the filter box 24 close to the roller 3, and an air suction cylinder 26 is fixedly installed on the end of the telescopic tube 25 away from the filter box 24, and both ends of the air suction cylinder 26 are fixedly connected to the L-shaped connecting plate 5 corresponding to the position, an air pump 29 is fixedly installed on the upper end of the filter box 24, and the input ends on both sides of the air pump 29 are connected to the filter box 24, and the upper end of the filter box 24 A connecting pipe 30 is fixedly installed on the output end, an exhaust pipe 31 is fixedly installed on the end of the connecting pipe 30 away from the vacuum pump 29, a pressure relief valve 49 is connected to the top of the inner cavity of the exhaust pipe 31, a connecting block 48 is fixedly installed between the exhaust pipe 31 and the baffle 46, and the connecting block 48 is used to support the exhaust pipe 31. When the cylinder 4 drives the suction cylinder 26 and the grinding wheel 10 to slide, the filter box 24 and the exhaust pipe 31 will not move, and the telescopic tube 25 performs telescopic movement during the sliding of the suction cylinder 26.

[0035] Specifically, refer to Figure 6 The inclination angle of the suction pipe 27 is fifty degrees toward the direction of the aluminum rod 47, so that when the heat dissipation groove 35 performs counterclockwise grinding on the aluminum rod 47, the generated dust can fly in the direction of the suction pipe 27. At the same time, during the grinding process, the vacuum pump 29 sucks air into the filter box 24 through the input ends on both sides, and then through the conduction of the telescopic tube 25 and the suction cylinder 26, the suction pipe 27 on the outer wall of the suction cylinder 26 can suck air, so that when the dust is ground by the grinding wheel 10, it can further float in the direction of the suction pipe 27, and finally be sucked into the filter box 24 through the suction pipe 27. At the same time, the heavy aluminum powder will fall into the collection bin 28. Then, when the dust enters the filter box 24, it needs to be sucked into the connecting pipe 30 by the suction pump 29. During the absorption process, it will first be filtered by the baffle 46, and then transported to the exhaust pipe 31 through the connecting pipe 30. At the same time, if the air pressure inside the exhaust pipe 31 is too high, the air will be discharged through the pressure relief valve 49.

[0036] Among them, the beating structure includes a row plate 32, and the row plate 32 can interfere with the outer wall of the grinding wheel 10. A torsion spring shaft 33 is fixedly installed at one end of the row plate 32 away from the grinding wheel 10. The torsion spring shaft 33 is rotatably connected to the side surface of the exhaust pipe 31. An arc scraper 50 is fixedly installed at one end of the row plate 32 away from the torsion spring shaft 33. The arc scraper 50 can interfere with the outer wall of the grinding wheel 10.

[0037] The outer surface of the row plate 32 near the grinding wheel 10 is provided with an air hole 38, and the row plate 32 is provided with an air groove 36 connected with the air hole 38. A hose 37 is fixedly installed between the air groove 36 and the exhaust pipe 31, and the hose 37 can be bent with the rotation of the row plate 32. A trapezoidal baffle 34 is slidably connected between the air hole 38 and the air groove 36, and the trapezoidal baffle 34 extends to the outer wall of the row plate 32 and is adapted to the heat dissipation groove 35. One side of the trapezoidal baffle 34 is penetrated by an opening A connecting groove 39 is provided, and the connecting groove 39 can be connected with the air groove 36. A plurality of springs 40 are fixedly installed between the lower end of the trapezoidal baffle 34 and the row plate 32. Baffles 46 are fixedly installed on both sides of the row plate 32, and the side surfaces of the baffles 46 are in contact with the two ends of the grinding wheel 10. A motor 41 is welded to the lower surface of the positioning frame 6, and a driving wheel 42 is fixedly installed at the output end of the motor 41. A driving belt 43 is commonly sleeved on the outer side wall of the driving wheel 42 and the driven ring 20.

[0038] Specifically, refer to Figure 6 The elastic restoring force generated by the torsion spring shaft 33 makes the row plate 32 always fit the grinding wheel 10 in the clockwise direction. At the same time, when the grinding wheel 10 is away from the row plate 32, the arc scraper 50 will contact the lower surface of the grinding wheel 10, and the surface of the arc scraper 50 is smooth. The friction generated by the grinding wheel 10 on the surface of the arc scraper 50 is small. When the heat dissipation groove 35 is embedded with excessive grinding debris, the arc scraper 50 will scrape it off to prevent the debris from contacting the aluminum rod 47 for the second time and damaging the outer surface of the aluminum rod 47. When the grinding wheel 10 is pushed by the cylinder 4 and moves in the direction of the row plate 32, the row plate 32 will be ground. The wheel 10 pushes and rotates slightly around the torsion spring shaft 33, so that the trapezoidal baffle 34 contacts the side surface of the grinding wheel 10. When the grinding wheel 10 rotates, the trapezoidal baffle 34 slides to the inside of the heat dissipation groove 35 and then passes through the bevel on the trapezoidal baffle 34 and is pushed out of the heat dissipation groove 35. Thereafter, the trapezoidal baffle 34 will repeatedly bump on the outer surface of the grinding wheel 10, so that the row plate 32 continuously swings and hits the outer surface of the grinding wheel 10, so that the dust on the outer surface of the grinding wheel 10 can be beaten out. At the same time, the grinding wheel 10 is fixed with a soft connection at this time, and a certain shaking will occur during the beating process, which promotes the falling of dust.

[0039] Furthermore, as the rotation speed of the grinding wheel 10 increases, the grinding wheel 10 will shake due to the influence of the eccentric block 21, and the shaking amplitude will be further increased by the beating of the row plate 32. At this time, during the violent shaking of the grinding wheel 10, when the trapezoidal baffle 34 is pushed out from the inside of the heat dissipation groove 35, the shaking of the grinding wheel 10 will cause the trapezoidal baffle 34 to be unable to immediately contact the outer side wall of the grinding wheel 10, thereby generating a drop. After the drop is generated, the grinding wheel 10 shakes and then hits the upper end of the trapezoidal baffle 34, so that the spring 240 at one end of the trapezoidal baffle 34 is hit and compressed by a large force, and the trapezoidal baffle 34 slides. The through groove 39 will be connected with the air groove 36, so that the air groove 36, the connecting groove 39 and the air hole 38 are connected. After the connection, the gas ejected from the vacuum pump 29 to the inside of the exhaust pipe 31 will flow out from the air hole 38, and the air hole 38 will then spray toward the outer surface of the grinding wheel 10 at an angle, thereby promoting the dust on the surface of the grinding wheel 10 to fall off. At the same time, there is an angle between the row plate 32 and the grinding wheel 10 at this time. When the air hole 38 sprays the surface of the grinding wheel 10, the air carrying dust will diffuse from the area of ​​the angle, and the direction of the angle is toward the direction of the suction pipe 27, so that the dust shed by the slapping and spraying will fly in the direction of the suction pipe 27, making it easier for the suction pipe 27 to absorb the dust.

[0040] Working principle: the positioning frame 6 is driven to slide by the cylinder 4, and the positioning frame 6 drives the positioning shaft 7 to move during the sliding process, so that the grinding wheel 10 outside the positioning shaft 7 moves in the direction away from the rubber wheel 2. During the movement, the inclined sliding block 22 is resisted by the inclined sliding plate 23 and slides in the direction away from the inclined sliding plate 23. During the sliding process of the inclined sliding block 22, the mounting block 8 is driven to slide. The sliding of the mounting block 8 makes the circular arc positioning plate 13 no longer resist the inner wall of the positioning groove 14, so that the circular arc positioning plate 2 18 is pushed to resist the inner wall of the positioning groove 2 19 through the elastic restoring force of the spring 17. When the speed of the grinding wheel 10 is accelerated, it is affected by the eccentric effect of the eccentric block 21, and the grinding wheel 10 will vibrate, thereby causing the dust on the outer surface of the grinding wheel 10 and the inside of the heat dissipation groove 35 to fall off. When the grinding wheel 10 is pushed in the direction away from the rubber wheel 2, the staff can replace the aluminum rod 47 that has been polished on the upper end of the roller 3.

[0041] Next, the suction pump 29 sucks air into the suction cylinder 26, and the suction cylinder 26 then sucks air toward the grinding position of the grinding wheel 10 through the suction pipe 27, so that the dust generated by grinding is sucked into the filter box 24, and then filtered through the baffle 46 and input into the exhaust pipe 31. When the grinding wheel 10 slides, the suction cylinder 26 slides together, and the dust generated by the vibration of the grinding wheel 10 is absorbed together, so as to prevent the dust generated by the grinding of the aluminum rod 47 from flying;

[0042] Finally, the arc scraper 50 is driven by the torsion spring shaft 33 to contact the outer wall of the grinding wheel 10, so that the large dust attached to the outer surface can be scraped off when the grinding wheel 10 rotates and grinds. After that, when the grinding wheel 10 rotates, the trapezoidal baffle 34 is inserted into the heat dissipation groove 35 and then pushed out, so that the row plate 32 is constantly bumped and slaps the outer wall of the grinding wheel 10, thereby promoting the dust on the outer surface of the grinding wheel 10 and the inside of the heat dissipation groove 35 to fall off. Then, the shaking generated by the grinding wheel 10 hits the trapezoidal baffle 34, so that the air hole 38 transmits the air from the vacuum pump 29 to the exhaust pipe 31 to eject, thereby promoting the cleaning of the dust on the surface of the grinding wheel 10. At the same time, through the angle generated between the row plate 32 and the grinding wheel 10, the blown dust will be pushed to diffuse from the position of the angle to flow in the direction of the intake pipe 27, thereby promoting the absorption of dust by the intake pipe 27.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
