Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing outer ring polishing device. Background Technology

[0002] In the bearing manufacturing industry, the surface quality of the bearing outer ring directly affects the bearing's assembly accuracy, operational stability, and service life. Polishing, as a key process in bearing outer ring processing, requires the removal of burrs, scratches, and oxide layers from the outer ring surface through grinding and lapping to achieve the surface roughness required by the design. This reduces frictional losses during bearing operation, lowers noise, and improves sealing performance. Existing bearing outer ring polishing equipment uses a single-unit polishing method, resulting in low processing efficiency.

[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN214080851U, published on August 31, 2021) provides a bearing outer ring polishing device. This device places multiple bearing outer rings onto positioning shafts. The bearing outer rings are housed within the gap between the polishing table and the polishing wheel. Then, a motor is activated, driving the polishing wheel to rotate. The bearing outer rings are then uniformly polished under the synergistic effect of the polishing table and the polishing wheel. Furthermore, since several positioning shafts are provided, and each positioning shaft can accommodate multiple bearing outer rings, multiple bearing outer rings can be polished simultaneously during the operation of the bearing outer ring polishing device, thereby improving the polishing effect on the bearing outer rings.

[0004] In the above-mentioned process, multiple bearings are fitted onto the positioning shaft and locked with nuts. Then, the bearings are polished using a polishing table. During this process, the specifications of the positioning shaft are fixed. When polishing bearings of different specifications, different models of positioning shafts need to be replaced, which makes the operation cumbersome and time-consuming. At the same time, debris is generated during the polishing process. If the debris is not handled in time, it will fly everywhere, which will affect the safety of the operators and the cleanliness of the work area. Utility Model Content

[0005] The purpose of this utility model is to provide a bearing outer ring polishing device to solve the problems mentioned in the background art. In the process of using the existing bearing outer ring polishing device, multiple bearings are sleeved on the positioning shaft and locked with nuts. Then, the bearings are polished by the polishing table. In this process, the specifications of the positioning shaft are fixed. When polishing bearings of different specifications, different models of positioning shafts need to be replaced, which makes the operation cumbersome and time-consuming. At the same time, during the polishing process, debris is generated. If the debris is not handled in time, it will fly everywhere, which will affect the safety of the operator and the cleanliness of the work area.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing outer ring polishing device, comprising a base, a rotating cylinder rotatably connected to the center of the top surface of the base, a positioning plate slidably disposed at equal angles on the outer side of the rotating cylinder, a bearing outer ring sleeved on the outer side of the positioning plate, and polishing discs connected to the four corners of the top of the base via electric push rods, the polishing discs contacting the surface of the bearing outer ring.

[0007] The rotary drum is equipped with an adaptive adjustment component, which adjusts the position and curvature of the positioning plate according to the specifications of the outer ring of the bearing being processed, thereby improving positioning stability.

[0008] The base has symmetrical dust collection plates on its top left and right sides. The dust collection plates are located around the outer ring of the bearing. The dust collection plates are connected to the dust pump on the rear side of the base through connecting pipes. The base and the inside of the rotating drum are equipped with a coordinating mechanism to drive the adjustment of the dust collection plates.

[0009] Furthermore, a first motor is installed inside the base, and the output end of the first motor is connected to a rotating drum. The rotating drum drives the outer ring of the bearing to rotate synchronously through a positioning plate.

[0010] Furthermore, the adaptive adjustment assembly includes a second motor installed inside the rotating drum. The output end of the second motor is connected to a first screw. The outer side of the middle part of the first screw is connected to the second screw through a bevel gear connector. The second screw is rotatably connected to the rotating drum. A positioning plate is threadedly connected to the outer side of the second screw, and a flange is installed on the outer side of the positioning plate.

[0011] Furthermore, the positioning plate forms a telescopic sliding structure through the second screw. The positioning plate is configured as a "T" shape when viewed from above, and the outer end of the positioning plate is configured as an arc shape. The outer end of the positioning plate abuts against the inner wall of the outer ring of the bearing.

[0012] Furthermore, both sides of the outer end of the positioning plate are hinged with sliding rods, which are slidably connected to the support cylinder, which is hinged to the outer middle part of the positioning plate.

[0013] Furthermore, the outer sides of the upper and lower sides of the first screw are threaded with pressure plates, which are slidably connected to the upper and lower sides inside the rotating drum. The bottom of the pressure plate is slidably sealed with the air chamber. The upper air chamber is connected to the inside of the support cylinder through a connecting pipe. After the slide rod slides out, the curvature of the positioning plate is adjusted so that it can better fit the inner wall of the outer ring of bearings of different specifications.

[0014] Furthermore, the collaborative mechanism includes symmetrically opened transverse grooves on the top of the base, a fixed cylinder is installed in the transverse groove, a slide is slidably connected in the fixed cylinder, a dust suction plate is installed on the top of the slide, and the fixed cylinder is connected to the air chamber on the lower side through a connecting pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This bearing outer ring polishing device adjusts the extension distance and curvature of the positioning plate according to the specific specifications of the bearing outer ring being processed during use. This better adapts to the bearing outer ring and more firmly positions and fixes it, avoiding the tedious operation of frequently changing positioning components. At the same time, the dust collection plate can be adjusted simultaneously while the positioning components are being adjusted, so that the waste chips during the polishing process can be cleaned up in a timely manner.

[0017] 1. Furthermore, the first screw bevel gear connector drives the second screw to rotate. The rotation of the second screw drives the positioning plate to extend and retract radially along the rotating drum, adjusting the extension distance to fit bearing outer rings of different diameters. At the same time, when the first screw rotates, it drives the upper and lower pressure plates to slide inside the rotating drum, compressing the air chamber and causing the internal gas to be transported through the connecting pipe to the support cylinder on the outer side of the middle of the positioning plate. The slide rod inside the support cylinder is pushed outward by the air pressure. Because the slide rod is hinged to the outer end of the positioning plate, the extension of the slide rod will cause the outer end of the positioning plate to unfold, adjusting its arc curvature to fit the bearing outer rings with different inner wall curvatures. Finally, through extension and retraction adjustment and curvature adaptation, a firm positioning is achieved, avoiding frequent replacement of positioning components.

[0018] 2. Furthermore, during the adjustment of the positioning plate, the gas generated by the pressure plate in the lower air chamber is simultaneously transported through the connecting pipe to the fixed cylinder in the horizontal groove at the top of the base. The slide in the fixed cylinder is pushed by the air pressure to slide along the horizontal groove, which drives the dust collection plate installed at the top to move synchronously, so that the dust collection plate can be close to the outer side of the outer ring of bearings of different specifications. In conjunction with the dust pump on the rear side of the base, negative pressure is generated through the connecting pipe to suck away the metal debris generated during the polishing process in real time, preventing debris from accumulating or splashing and affecting the polishing accuracy and operational safety.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1 - Figure 2 and Figure 4 As shown, this utility model provides the following technical solution: a bearing outer ring polishing device, including a base 1, a rotating cylinder 3 rotatably connected to the center of the top surface of the base 1, a positioning plate 4 slidably arranged at equal angles on the outer side of the rotating cylinder 3, a bearing outer ring 6 sleeved on the outer side of the positioning plate 4, polishing discs 8 connected to the four corners of the top of the base 1 by electric push rods 7, the polishing discs 8 contacting the surface of the bearing outer ring 6, an adaptive adjustment component is provided inside the rotating cylinder 3, and the adaptive adjustment component adjusts the position and curvature of the positioning plate 4 according to the specifications of the bearing outer ring 6 to improve positioning stability, dust suction plates 9 are symmetrically arranged on the left and right sides of the top of the base 1, the dust suction plates 9 are located outside the bearing outer ring 6, the dust suction plates 9 are connected to the dust suction pump 10 on the rear side of the base 1 through a connecting pipe, and a coordinating mechanism for adjusting the dust suction plates 9 is provided inside the base 1 and the rotating cylinder 3.

[0028] like Figure 1 - Figure 4As shown, the usage process is as follows: The bearing outer ring 6 to be tested is placed on the positioning plate 4 outside the rotating drum 3. Then, the positioning plate 4 is accurately positioned for bearing outer rings 6 of different specifications through the adaptive adjustment component. The electric push rod 7 drives the polishing plate 8 to fit against the outer wall of the bearing outer ring 6. With the help of the cooperative mechanism, the dust suction plate 9 is synchronously adapted with the positioning adjustment. The dust suction pump 10 provides suction for the dust suction plate 9. After the rotating drum 3 rotates, the bearing outer ring 6 can be rotated for polishing. The coordinated operation of rotary polishing and real-time dust suction effectively solves the problems of cumbersome positioning and untimely dust removal in traditional devices. It realizes efficient, stable and clean polishing of bearing outer ring 6. The integrated mechanism of adaptive positioning adjustment, synchronous dust suction and efficient rotary polishing achieves accurate positioning, real-time dust removal and uniform polishing of bearing outer rings 6 of different specifications. Through the linkage of the positioning plate 4, the dust suction plate 9 and the polishing component, the polishing efficiency and quality stability are effectively improved.

[0029] Example 2:

[0030] Based on Embodiment 1, a precise positioning mechanism is also disclosed; please refer to [reference needed]. Figure 1 - Figure 2 and Figure 5 - Figure 6 As shown, its specific structure is as follows: A first motor 2 is installed inside the base 1. The output end of the first motor 2 is connected to a rotating drum 3. The rotating drum 3 drives the outer ring 6 of the bearing to rotate synchronously through the positioning plate 4. The adaptive adjustment component includes a second motor 11 installed inside the rotating drum 3. The output end of the second motor 11 is connected to a first screw 12. The outer side of the middle part of the first screw 12 is connected to a second screw 13 through a bevel gear connector. The second screw 13 is rotatably connected to the rotating drum 3. The outer side of the second screw 13 is threadedly connected to the positioning plate 4. A flange 5 is installed on the outer side of the positioning plate 4. The positioning plate 4 forms a telescopic sliding structure through the second screw 13. The positioning plate 4 is shaped like a "T" when viewed from above. The positioning plate 4 has an arc-shaped structure at its outer end, which abuts against the inner wall of the bearing outer ring 6. Both sides of the outer end of the positioning plate 4 are hinged with slide rods 17, which are slidably connected to the support cylinder 16. The support cylinder 16 is hinged to the outer middle part of the positioning plate 4. The outer sides of the first screw 12 are threaded with pressure plates 14, which are slidably connected to the upper and lower sides inside the rotating cylinder 3. The bottom of the pressure plate 14 is slidably connected to the air chamber 15. The upper air chamber 15 is connected to the inside of the support cylinder 16 through a connecting pipe. After the slide rods 17 slide out, the curvature of the positioning plate 4 is adjusted so that it fits better against the inner wall of the bearing outer ring 6 of different specifications.

[0031] refer to Figure 1 - Figure 2 and Figure 5 - Figure 6As shown, during use, the adaptive adjustment component achieves precise positioning of the bearing outer ring 6. Before processing, according to the specifications of the bearing outer ring 6, the second motor 11 inside the rotating drum 3 is started. The second motor 11 drives the first screw 12 to rotate, which in turn drives the second screw 13 inside the rotating drum 3 to rotate synchronously through the bevel gear connector. Since the positioning plate 4 is threadedly connected to the second screw 13, and the positioning plate 4 is slidably set on the outside of the rotating drum 3, the rotation of the second screw 13 will drive the positioning plate 4 to extend and retract radially along the rotating drum 3, adjusting the extension distance to adapt to bearing outer rings 6 of different diameters. Meanwhile, when the first screw 12 rotates, it drives the upper and lower pressure plates 14 to slide inside the rotating drum 3, compressing the air chamber 15 so that the internal gas is transported through the connecting pipe to the support cylinder 16 on the outer side of the middle part of the positioning plate 4. The slide rod 17 inside the support cylinder 16 is pushed outward by the air pressure. Since the slide rod 17 is hinged to the outer end of the positioning plate 4, the extension of the slide rod 17 will drive the outer end of the positioning plate 4 to unfold, adjusting its arc curvature to fit the bearing outer ring 6 with different inner wall curvatures. Finally, through extension and retraction adjustment and curvature adaptation, a firm positioning is achieved, avoiding frequent replacement of positioning components.

[0032] Example 3:

[0033] Based on Embodiment 2, a dust collection coordination adjustment mechanism is also disclosed; please refer to [reference needed]. Figure 3 - Figure 6 As shown, its specific structure is as follows: The collaborative mechanism includes a horizontal groove 18 symmetrically opened on the top of the base 1, a fixed cylinder 19 installed in the horizontal groove 18, a slide 20 slidably connected in the fixed cylinder 19, a dust suction plate 9 installed on the top of the slide 20, and the fixed cylinder 19 is connected to the air chamber 15 on the lower side through a connecting pipe.

[0034] like Figure 3 - Figure 6 As shown, during use, the coordinating mechanism drives the dust-collecting plate 9 to move synchronously with the positioning adjustment. During the adjustment of the positioning plate 4, the gas generated by the pressure plate 14 squeezing the lower air chamber 15 is simultaneously transported through the connecting pipe to the fixed cylinder 19 in the horizontal groove 18 at the top of the base 1. The slide 20 in the fixed cylinder 19 is pushed by the air pressure to slide along the horizontal groove 18, driving the dust-collecting plate 9 installed at the top to move synchronously, so that the dust-collecting plate 9 can be close to the outer side of the outer ring 6 of different specifications of bearings. In conjunction with the dust pump 10 on the rear side of the base 1, a negative pressure is generated through the connecting pipe to suck up the dust during the polishing process in real time. To prevent the accumulation or splashing of metal shavings from affecting polishing accuracy and operational safety, the first motor 2 inside the base 1 starts, driving the rotating drum 3 to rotate the positioning plate 4 and the outer ring of the bearing 6 synchronously. At the same time, the electric push rods 7 at the four corners of the top of the base 1 extend, pushing the polishing pad 8 into close contact with the surface of the outer ring of the bearing 6. The surface polishing is achieved by the rotation of the outer ring of the bearing 6 and the squeezing friction of the polishing pad 8. During the polishing process, the dust suction plate 9 continuously sucks up the shavings, while the positioning plate 4 ensures that the outer ring of the bearing 6 rotates smoothly by stable clamping, avoiding uneven polishing caused by shaking.
