Abstract

The application belongs to the field of bearing processing, and particularly relates to a surface burr removing device for automobile bearings, which comprises a lifting platform, a fixing plate, a collecting ring, a first liquid guide pipe and the like. By adopting the application, the inner wall of the polishing head polishing part is cooled by warm water after being pre-cooled by cold water in contact with the first baffle, the second baffle and the heat conduction plate, so as to avoid the direct contact of the cold water with the high-temperature polishing head for cooling, and further avoid the too fast temperature reduction of the polishing head, which affects the performance and service life of the polishing head. The polishing block is further cooled by the warm water from the outer surface of the polishing block, and the inner wall of the bearing outer ring is washed and cooled at the same time, so as to prevent the high-temperature burn and deformation of the polishing block and the bearing outer ring due to polishing. The problem of the direct contact of the cold water with the high-temperature polishing head, which causes the too fast temperature reduction of the polishing head and leads to the reduction of the service life of the polishing head, is solved.

Description

TECHNICAL FIELD

[0001] The application belongs to the field of bearing processing, and particularly relates to a surface burr removing device for automobile bearings. BACKGROUND

[0002] In the prior art, when polishing a bearing, cold water is usually sprayed to cool the polishing head and the bearing. The cold water splashes everywhere immediately after contacting the polishing head, and cannot sufficiently cool the polishing head. As the polishing time increases, the temperature of the polishing head gradually increases. When the cold water directly contacts the high-temperature polishing head, the temperature of the polishing head decreases too fast, which causes the polishing head to bear a large thermal stress and reduces the service life of the polishing head. In addition, the sizes of burrs on the bearing are different, and the polishing amount required by different areas of the bearing is different. The existing device cannot monitor the polishing condition in real time, and frequent shutdown is required to observe the polishing condition, which is prone to over-polishing. SUMMARY

[0031] The polishing assembly comprises second water pipes 203, first return springs 204, a polishing block 205 and second liquid guide pipes 206; the polishing block 205 is slidingly connected in the mounting cylinder 103; the polishing block 205 is fixedly connected with and communicated with two second water pipes 203 on the side of the center of the mounting cylinder 103; one first return spring 204 is sleeved on each of the two second water pipes 203; the two first return springs 204 are fixedly connected with the mounting cylinder 103, and the two first return springs 204 are fixedly connected with the polishing block 205; the two second water pipes 203 are slidingly connected with the mounting cylinder 103; the upper second water pipe 203 is communicated with the mounting cylinder 103; the lower second water pipe 203 is fixedly connected with and communicated with the second liquid guide pipe 206; a plurality of water spraying pipes 004 are arranged on the second liquid guide pipe 206 and face the inner wall of the bearing outer ring 005 and the polishing block 205.

[0032] The polishing assembly further comprises limiting frames 301 and buckles 302; the polishing block 205 is arranged in a detachable structure and comprises a polishing head 001 and a mounting seat 002, two limiting frames 301 are inserted into the polishing head 001 and the mounting seat 002, and a limiting rod for limiting the polishing head 001 and the mounting seat 002 is arranged on the limiting frame 301; two buckles 302 are arranged on each limiting frame 301, a buckle groove matched with the buckle 302 is arranged on the mounting seat 002, and all the buckles 302 are clamped with the mounting seat 002; when the polishing head 001 needs to be replaced, the limiting frame 301 is taken out of the polishing head 001 and the mounting seat 002, and the polishing head 001 is taken out of the mounting seat 002, so that the polishing head 001 can be replaced.

[0033] The polishing assembly further comprises first partitions 401, second partitions 402, heat-conducting plates 403 and third water pipes 404; the first partitions 401 and the second partitions 402 are fixedly connected to the inner wall of the polishing head 001, the first partitions 401 divide the polishing head 001 into two isolated cavities, and a space for water flow is arranged between the lower side of the second partitions 402 and the inner wall of the polishing head 001; a through groove communicated with the outside is formed in the top of the polishing head 001, and an electric control valve is arranged in the through groove; the third water pipes 404 are fixedly connected with and communicated with the upper second water pipes 203; a plurality of heat-conducting plates 403 are fixedly connected between the first partitions 401 and the second partitions 402, and the first partitions 401 and the second partitions 402 are made of heat-conducting metal materials; a through hole 003 opposite to the third water pipes 404 is formed in the first partitions 401.

[0034] When working, the bearing outer ring 005 is placed on the lifting platform 1, and then the lifting platform 1 drives the bearing outer ring 005 to rise, so that the inner wall of the bearing outer ring 005 extrudes the polishing head 001, and then the mounting seat 002 drives the second water pipe 203 to slide in the mounting cylinder 103, so that the first reset spring 204 is compressed, and when the inner wall of the bearing outer ring 005 is completely attached to the polishing head 001, the first reset spring 204 releases the elastic force to make the mounting seat 002 drive the second water pipe 203 to move back to the original position. At this time, the bearing outer ring 005 is fixed by clamping the outer ring surface of the bearing outer ring 005 by the external clamping device, and the first water pipe 202 is connected to the water supply device, and the cold water is sent into the mounting cylinder 103 through the fixed pipe 201, and then the cold water is introduced into the second water pipe 203 above and sprayed out through the third water pipe 404, and then enters the space between the first partition plate 401 and the second partition plate 402 through the through hole 003 on the first partition plate 401. During this process, the valve in the top slot of the polishing head 001 needs to be opened to make the inside of the polishing head 001 communicate with the outside, so that the air in the polishing head 001 can be normally discharged along the slot, otherwise the cold water cannot normally fill the inside of the polishing head 001 due to the influence of air pressure. With the injection of cold water, the cold water gradually fills the cavity near the bearing center inside the polishing head 001, and when the cavity is filled, the valve in the slot is closed. Then continue to inject cold water into the second water pipe 203, and the excess cold water will flow into the cavity far away from the bearing center inside the polishing head 001, and then the second water pipe 203 below discharges to flow.

[0035] Then the driving motor 105 is started, the output shaft of the driving motor 105 drives the flat gear 106 to rotate the gear ring 104, the gear ring 104 drives the mounting cylinder 103 to rotate in the fixed ring 102, the mounting cylinder 103 drives the polishing assembly to rotate, and the inner wall of the bearing outer ring 005 is polished by the polishing head 001 to remove burrs. After starting the polishing work, the water injection speed of the third water pipe 404 after starting the polishing can be adjusted according to the difficulty of polishing, that is, the rotating speed of the polishing head 001, because the rotation produces centrifugal force on the cold water, although the through hole 003 is relatively small and is located at a high position, and the curved channel formed by arranging the second partition plate 402, the water in the internal cavity near the bearing center inside the polishing head 001 will not produce a large-scale backflow phenomenon through the through hole 003, but will be inevitably affected. Therefore, the cavity can be kept with enough water by increasing the water output of the third water pipe 404.

[0036] In this process, polishing will cause the temperature of the polishing head 001 to rise rapidly, and the cold water will first contact the first partition plate 401, the second partition plate 402 and the heat conduction plate 403 to absorb part of the heat, and be heated to become warm water. Then the heated warm water fills the polishing head 001 and contacts the inner wall of the polishing part of the polishing head 001, realizing heat conduction by the first partition plate 401, the second partition plate 402 and the heat conduction plate 403. Through the pre-cooling of the cold water in contact with the first partition plate 401, the second partition plate 402 and the heat conduction plate 403, and then through the warm water after heating to cool the inner wall of the polishing part of the polishing head 001, it is avoided that the cold water directly contacts the direct polishing area of the high-temperature polishing head 001 for cooling, thereby avoiding that the temperature of the polishing head 001 decreases too fast to affect its performance and service life. Because the water temperature in the internal cavity of the polishing head 001 close to the bearing center increases, the heat is conducted to the first partition plate 401, and then from the internal cavity of the polishing head 001 away from the bearing center, through the upper second water pipe 203 into the lower second water pipe 203, the flowing cold water flows out to cool the first partition plate 401, so as to maintain the constant temperature of the warm water. Finally, the water heated in the polishing block 205 is guided out through the lower second water pipe 203, sprayed into the inner wall of the bearing outer ring 005 and the outer surface of the polishing block 205 through the water spray pipe 004 on the second liquid guide pipe 206, and then the warm water further cools the polishing block 205 through the outer surface of the polishing block 205, and at the same time, the bearing outer ring 005 is washed and cooled to prevent the polishing block 205 and the bearing outer ring 005 from being burned and deformed due to high temperature generated by polishing.

[0037] Embodiment 2

[0038] Based on the embodiment 1, as shown in Figures 3-5 It further comprises an oil pipe 501, a control valve 502 and an adjusting unit; the oil pipe 501 is fixedly connected in the fixed pipe 201; the mounting cylinder 103 is provided with a circular groove 006; the mounting cylinder 103 is rotationally connected with the oil pipe 501, and the oil pipe 501 is in communication with the circular groove 006; the oil pipe 501 is provided with the control valve 502; the mounting cylinder 103 is connected with four adjusting units; each adjusting unit is connected with one polishing assembly.

[0039] The adjusting unit comprises an oil cylinder 503, a piston rod 504, a first oil guide pipe 505, a second oil guide pipe 506, an oil storage bag 507, a fixed sheet 508 and a second reset spring 509; the oil cylinder 503 is fixedly connected in the mounting cylinder 103; the piston rod 504 is slidably connected in the oil cylinder 503, and the piston rod 504 is in contact with the first partition plate 401 on the side away from the center of the mounting cylinder 103; the piston rod 504 is slidably connected with a polishing block 205; the first oil guide pipe 505 is fixedly connected and communicated with the oil cylinder 503; the first oil guide pipe 505 is communicated with the circular groove 006; four second oil guide pipes 506 are fixedly connected and communicated with the oil cylinder 503 on the side away from the first oil guide pipe 505; the oil storage bag 507 is commonly communicated with all the second oil guide pipes 506; the fixed sheet 508 is fixedly connected with the piston rod 504; the second reset spring 509 is fixedly connected with the fixed sheet 508; and the second reset spring 509 is fixedly connected with the polishing block 205.

[0040] The electronic oil pressure gauge 510 is further included; the electronic oil pressure gauge 510 is arranged on the oil delivery pipe 501 and located below the control valve 502; and the oil pressure in the oil delivery pipe 501 is monitored through the electronic oil pressure gauge 510.

[0041] The trapezoidal block 601 and the conical head 602 are further included; one conical head 602 is fixedly connected with each limiting rod of the limiting frame 301; the trapezoidal block 601 is fixedly connected with the piston rod 504 on the side away from the center of the mounting cylinder 103; and the trapezoidal block 601 is in contact with the first partition plate 401.

[0042] Because the burrs on the bearing outer ring 005 are different in size and length, the polishing amount required for different areas of the bearing is different. If the polishing head 001 is directly attached to the surface of the bearing, the protruding long burrs can be easily flattened during the rotation and polishing process. After flattening, the burrs are polished, which can also cause the contact probability of other areas without burrs with the polishing head 001 to increase, which can increase the possibility of over-polishing, increase the difficulty of polishing, and prolong the time. Open the control valve 502, deliver hydraulic oil into the oil delivery pipe 501 through the hydraulic oil delivery device, and then guide the oil into the oil cylinder 503 through the first oil guide pipe 505, push the piston rod 504 to slide in the oil cylinder 503, and the piston rod 504 pushes part of the hydraulic oil in the oil cylinder 503 into the oil storage bag 507 through the second oil guide pipe 506, so that the oil storage bag 507 expands, and at the same time, the piston rod 504 pushes the first partition plate 401, and then the polishing block 205 moves away from the center of the mounting cylinder 103, thereby increasing the polishing amount of the inner wall of the bearing outer ring 005. By this method, the possibility of over-polishing can be reduced, and the gap between the polishing head 001 and the bearing is gradually reduced during the polishing process. Therefore, the polishing debris or dust generated in the early stage of the polishing process has more space to be discharged from the gap. If the polishing head 001 is directly pushed to the bottom, all polishing debris or dust needs to be discharged through the narrow gap, which is slow and can hinder the polishing process.

[0043] When the polishing head 001 needs to be replaced, the device is not working, and the polishing head 001 is manually pulled to make the polishing block 205 slide on the piston rod 504, so that the second reset spring 509 is stretched, and at the same time, the polishing block 205 moves the second water delivery pipe 203, so that the first reset spring 204 is stretched, and then the trapezoidal block 601 presses the conical head 602. At this time, the limiting frame 301 and the buckle 302 are outside the mounting cylinder 103, and then the limiting frame 301 is quickly ejected from the polishing head 001 and the mounting seat 002 by pressing the conical head 602 through the trapezoidal block 601, so that the buckle 302 is separated from the mounting seat 002, and then the limiting frame 301 is taken out, and the polishing head 001 is quickly replaced.
