Description

Technical Field

[0001] The present application relates to the technical field of bearing ring processing, and particularly relates to a bearing ring polishing device for bearing production and processing. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotational accuracy. According to the different friction properties of the moving elements, bearings can be divided into two major categories: rolling bearings and sliding bearings.

[0003] During the production process of bearings, it is necessary to polish the inner and outer circumferential sides of the bearing rings. However, when the existing bearing ring polishing devices are in use, they can only polish the inner circumferential side or the outer circumferential side of the bearing ring once. When polishing, two polishing operations are required. Since it needs to be fixed during polishing, it needs to be installed or removed twice, thus affecting the polishing efficiency. Therefore, the present application proposes a bearing ring polishing device for bearing production and processing. Utility Model Content

[0004] The purpose of the present application is to solve the problem that when the existing polishing device polishes the inner and outer circumferential sides of the bearing ring, it can only polish one side of the bearing ring at a time, and two operations are required, thus affecting the polishing efficiency.

Detailed implementation manners

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0028] As Figures 1-7 shown, a bearing ring polishing device for bearing production and processing proposed in an embodiment of the present application includes:

[0029] Base 1, the base 1 includes a base plate, and supports are installed at the four corners of the bottom of the base plate;

[0030] The rotating guide member 2 includes a plurality of first vertical plates 201 arranged in an annular array on the top of the base 1. A plurality of adjusting rods 202 are slidably penetrated through the plurality of first vertical plates 201. Guide wheels 203 are rotatably arranged at one ends of the plurality of adjusting rods 202 close to each other. An adjusting part 204 is arranged on the base 1 for adjusting the synchronous reverse movement of the plurality of adjusting rods 202. Preferably, the guide wheels 203 are vertically rotatably arranged on the adjusting rods 202. When guiding the bearing ring, first, the adjusting part 204 is used to adjust the plurality of adjusting rods 202 to slide close to each other synchronously. The bearing ring is placed on the plurality of adjusting rods 202, so that the plurality of guide wheels 203 are located inside the bearing ring. Then, the adjusting part 204 is used to adjust the plurality of adjusting rods 202 to slide away synchronously, so that the plurality of guide wheels 203 abut and overlap the inner side of the bearing ring. Since the guide wheels 203 are rotatably arranged on the adjusting rods 202, the bearing ring can be positioned and its normal rotation is not affected;

[0031] The rotating grinding member 3 includes two second vertical plates 301 arranged on the top of the base 1. Two sliding rods 302 are connected between the two second vertical plates 301. Two first support plates 303 and two second support plates 304 are slidably arranged on the two sliding rods 302. Grinding wheels 305 penetrate through the two first support plates 303. Rotating wheels 306 are rotatably arranged on the two second support plates 304. Preferably, as Figure 1 shown, when placing the bearing ring, a section of the ring body of the bearing ring is located between the two grinding wheels 305, and a section of the ring body is located between the two rotating wheels 306. An adjusting member 307 and a driving member 308 are arranged between the two second vertical plates 301. The adjusting member 307 is used to adjust the synchronous reverse sliding of the two first support plates 303 and the synchronous reverse sliding of the two second support plates 304. The driving member 308 is used to drive the two grinding wheels 305 to rotate synchronously in the reverse direction and drive the two rotating wheels 306 to rotate synchronously in the reverse direction. After the bearing ring is placed, the adjusting member 307 is used to adjust the synchronous reverse sliding of the two first support plates 303, so that the two grinding wheels 305 abut and overlap the inner and outer side walls of the bearing ring. The two second support plates 304 are adjusted to slide synchronously in the reverse direction, so that the two rotating wheels 306 clamp and abut the inner and outer side walls of the bearing ring. Then, the driving member 308 drives the two rotating wheels 306 to rotate synchronously in the reverse direction, and the stress of the synchronous reverse rotation of the two rotating wheels 306 is used to drive the bearing ring to rotate. The driving member 308 drives the two grinding wheels 305 to rotate synchronously in the reverse direction, so that the two grinding wheels 305 respectively grind the inner and outer sides of the bearing ring. When the bearing ring rotates, its inner and outer walls are evenly ground;

[0032] The bearing ring is supported and rotated by a plurality of guide wheels 203 to position it without affecting its normal rotation. The two rotating wheels 306 rotate synchronously in opposite directions, thereby driving the bearing ring to rotate under the stress of rotational resistance. When the bearing ring rotates, the two grinding wheels 305 grind its inner and outer walls, so that the inner and outer walls of the bearing ring are synchronously grinded at one time, thereby improving the grinding and polishing efficiency.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the adjusting portion 204 includes a rotating shaft 2041 that rotates and penetrates the base 1, a disc 2042 is fixedly provided on the rotating shaft 2041, a plurality of support rods 2043 are eccentrically hinged on the disc 2042, and the free ends of the plurality of support rods 2043 are respectively hinged to the plurality of adjusting rods 202, a worm gear 2044 is fixedly provided on the rotating shaft 2041, a worm 2045 that is transmission-engaged with the worm gear 2044 is rotationally provided on the base 1, and the worm gear 2045 is twisted to rotate, and the worm gear 2045 is transmission-engaged with the worm gear 2044, Thereby, the rotating shaft 2041 and the disk 2042 can be driven to rotate synchronously. Since the support rod 2043 is eccentrically hinged on the disk 2042, when the disk 2042 rotates, several support rods 2043 respectively pull or resist several adjusting rods 202 to achieve the function of adjusting the several adjusting rods 202 to slide closer or away synchronously. At the same time, the meshing of the worm 2045 and the worm wheel 2044 is self-locking, so that the rotating shaft 2041 can be self-locked after being rotated to ensure the stability of the bearing ring rotation guide.

[0034] like Figure 6 and Figure 7 As shown, in some embodiments, the adjusting member 307 includes two bidirectional screw rods 3071, and the two bidirectional screw rods 3071 rotate and penetrate the two second vertical plates 301 respectively. The two first support plates 303 are respectively threadedly sleeved on the two ends of one of the bidirectional screw rods 3071, and the two second support plates 304 are respectively threadedly sleeved on the two ends of the other bidirectional screw rod 3071. One of the bidirectional screw rods 3071 is twisted to rotate, and under the action of the bidirectional thread, the two first support plates 303 are driven to slide in the opposite direction synchronously. The other bidirectional screw rod 3071 is twisted, and under the action of the bidirectional thread, the two second support plates 304 are driven to slide in the opposite direction synchronously. At the same time, the thread cooperation between the first support plate 303 and the second support plate 304 and the bidirectional screw rod 3071 is self-locking to ensure its stability after adjustment.

[0035] like Figure 4As shown, in some embodiments, two bidirectional lead screws 3071 are coaxially arranged and their relative ends are fixedly connected. Connecting the two bidirectional lead screws 3071 coaxially and fixing them enables twisting one of the bidirectional lead screws 3071 to drive the other bidirectional lead screw 3071 to rotate synchronously. When installing or removing the bearing ring, only one bidirectional lead screw 3071 needs to be rotated, thereby improving convenience.

[0036] As Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the driving member 308 includes a spline rod 3081 that rotatably penetrates through two second vertical plates 301. One end of the spline rod 3081 is connected to a motor 3082 disposed on one of the second vertical plates 301. Four spline sleeves 3083 are slidably sleeved on the spline rod 3081. The four spline sleeves 3083 are respectively rotatably connected to two first support plates 303 and two second support plates 304. Preferably, both the first support plate 303 and the second support plate 304 are configured as rectangular frame structures. L-shaped plates are connected to both the first support plate 303 and the second support plate 304. The spline sleeve 3083 is rotatably disposed on the L-shaped plate. Driven bevel gears 3084 are fixedly provided on both two grinding wheels 305 and two rotating wheels 306. Driving bevel gears 3085 are fixedly provided on the four spline sleeves 3083. The four driving bevel gears 3085 are respectively in tooth engagement with the four driven bevel gears 3084. Since the spline sleeve 3083 and the spline rod 3081 are in spline fit, the spline sleeve 3083 can slide in the axial direction along the spline rod 3081. At the same time, when the spline rod 3081 rotates, it can drive the spline sleeve 3083 to rotate synchronously. Since the spline sleeve 3083 is rotatably connected to the first support plate 303 and the second support plate 304 through the L-shaped plate, no matter how the first support plate 303 and the second support plate 304 are moved and adjusted, the driving bevel gear 3085 and the driven bevel gear 3084 always remain in an engaged state. When the motor 3082 does work, its output shaft drives the spline rod 3081 to rotate, thereby driving the four spline sleeves 3083 and the four driving bevel gears 3085 to rotate synchronously. By using the tooth engagement between the driving bevel gear 3085 and the driven bevel gear 3084, two grinding wheels 305 and two rotating wheels 306 are driven to rotate synchronously. It should be noted that the two driving bevel gears 3085 corresponding to the two grinding wheels 305 are oppositely arranged, so the two grinding wheels 305 rotate synchronously in opposite directions. The two driving bevel gears 3085 corresponding to the two rotating wheels 306 are oppositely arranged. Therefore, the two rotating wheels 306 rotate synchronously in opposite directions.

[0037] As Figure 2As shown, in some embodiments, a through groove 4 is formed through one end of the adjusting rod 202 close to the guide wheel 203. A supporting wheel 5 is rotatably arranged on opposite sides of the inner wall of the through groove 4. Through the formed through groove 4 and the supporting wheel 5 rotatably arranged in the through groove 4, when placing the bearing ring, the bearing ring is lapped on the supporting wheel 5, so that the bearing ring does not contact the adjusting rod 202, thereby reducing the contact friction force and making the rotation of the bearing ring smoother.

[0038] As Figure 6 shown, in some embodiments, a rubber sleeve 6 is fixedly arranged on the outer surface of the rotating wheel 306. A plurality of annularly distributed ridges are arranged in an array on the outer surface of the rubber sleeve 6. Through the arranged rubber sleeve 6 and the ridges, by utilizing the deformable property of its material, the contact friction force between the rotating wheel 306 and the bearing ring is increased, so that the rotation effect of the two rotating wheels 306 on the bearing ring is better and the rotation is more stable.

[0039] As shown in 7, in some embodiments, the grinding wheel 305 adopts a hundred-leaf wheel, and the hundred-leaf wheel is called a strong elastic grinding disc. By adopting the hundred-leaf wheel as the grinding wheel 305, it is not necessary to make hard contact and lap with the bearing ring. When ensuring that the two rotating wheels 306 make effective rotational contact with the bearing ring, the grinding wheel 305 will not only interfere with the rotation of the bearing ring, but also can effectively grind the bearing ring.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
