Description

Technical Field

[0001] This utility model belongs to the technical field of bearing ring processing equipment, and in particular relates to a rolling ring device for bearing ring preparation. Background Technology

[0002] According to the published patent CN215237499U, a rolling device for automotive clutch bearing rings includes a placement platform. A fixed frame is provided on one side of the placement platform. An internal gear ring is provided on the inner wall of the top of the fixed frame. A driving gear is provided inside the top of the fixed frame. A driven gear is provided between the driving gear and the internal gear ring. A slotted plate is provided on the outer side of the bottom of the driven gear. The position of the clamping plates can be adjusted by a hydraulic cylinder, allowing four clamping plates to clamp and fix bearing rings of different sizes. Simultaneously, a support plate provides support for the bearing rings. Furthermore, the driven gear can rotate within the inner wall of the fixed frame due to the driving gear and the internal gear ring. However, the following shortcomings still exist: While the aforementioned equipment can clamp and fix the bearing rings during use, the fixed position of the slotted plate prevents adjustment of the diameter of the slotted plate's movement trajectory. Therefore, when rolling bearing rings, only workpieces of the same diameter can be produced, reducing the applicability of the device. Thus, we propose a rolling device for bearing ring preparation. Utility Model Content

[0003] The purpose of this utility model is to provide a rolling device for preparing bearing rings. Through the positioning mechanism and auxiliary mechanism, it solves the problem that although the above-mentioned equipment can clamp and fix the bearing rings, the diameter of the grooved plate cannot be adjusted due to the fixed position of the grooved plate. Therefore, when rolling the bearing rings, only workpieces of the same diameter can be processed, which reduces the applicability of the device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a rolling device for preparing bearing rings, including an operating table, a bearing ring being slidably connected to the top outer wall of the operating table, and a positioning mechanism being provided on the outer wall of the operating table. The positioning mechanism includes a roller, a drive shaft is fixedly connected to the inner wall of the roller, a motor is fixedly connected to the top outer wall of the drive shaft, a motor frame is fixedly connected to the outer wall of the motor, a fixing block is fixedly connected to the top outer wall of the operating platform near the roller, several telescopic rods are fixedly connected to the outer wall of the fixing block near the bearing ring, several springs are fixedly connected to the outer wall of the telescopic rods near the fixing block, a rotating shaft is rotatably connected to the inner wall of the telescopic rod away from the fixing block, a second roller is fixedly connected to the outer wall of the rotating shaft, a third roller is slidably connected to the inner wall of the bearing ring away from the roller, a second rotating shaft is fixedly connected to the outer wall of the third roller, a hydraulic cylinder is rotatably connected to the outer wall of the second rotating shaft, and an auxiliary mechanism is provided on the outer wall of the operating platform.

[0005] Furthermore, the outer wall of the roller is slidably connected to the inner wall of the bearing ring, the outer walls of several springs are fixedly connected to the outer wall of the fixing block, the outer wall of the second roller is slidably connected to the outer wall of the bearing ring, and the outer wall of the hydraulic cylinder is fixedly connected to the outer wall of the operating table.

[0006] Furthermore, the auxiliary mechanism includes several electric telescopic rods, the outer walls of which are fixedly connected to the inner wall of the operating table. A connecting plate is fixedly connected to the bottom output end of each electric telescopic rod, and the outer wall of the connecting plate is slidably connected to the inner wall of the operating table.

[0007] Furthermore, the outer wall of the connecting plate is fixedly connected to the outer wall of the motor frame, and the inner wall of the connecting plate is provided with a plurality of limiting grooves, and the inner walls of the plurality of limiting grooves are slidably connected with sliders.

[0008] Furthermore, each of the bottom outer walls of the slider is fixedly connected to a rotating shaft three, and the outer wall of the rotating shaft three is rotatably connected to a roller four, and the outer walls of several roller four are slidably connected to the outer wall of the bearing ring.

[0009] Furthermore, a support block is fixedly connected to the top outer wall of the connecting plate, and a worm gear is rotatably connected to the inner wall of the support block.

[0010] Furthermore, a rotating shaft four is rotatably connected to the central axis of the top outer wall of the connecting plate near the worm, and a worm wheel is fixedly connected to the outer wall of the rotating shaft four near the worm, with the outer wall of the worm wheel meshing with the outer wall of the worm.

[0011] Furthermore, a connecting rod is fixedly connected to the outer wall of the rotating shaft four, and several connecting rods two are rotatably connected to the outer wall of the connecting rod. The inner wall of the connecting rod two is rotatably connected to the outer wall of the slider.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a telescopic rod on a fixed block. When the equipment is in use, the motor rotation drives the transmission shaft to rotate, causing the rollers to rotate. Because the third roller at the other end tightens the bearing ring, and the spring, through its own elasticity, constantly compresses the rotating shaft, causing the second roller to always press against the outer wall of the bearing ring, the third roller rotates, causing the bearing ring to rotate. At this time, the hydraulic cylinder is activated, causing the second rotating shaft and the third roller to gradually move away from the rollers. This achieves a certain degree of limiting effect on the bearing ring during the ring rolling process, preventing significant displacement during the rolling process. Furthermore, by rotating the bearing ring, the rolling accuracy of the device can be improved.

[0013] 2. This utility model incorporates sliders within a limiting groove. During operation, rotating the worm gear drives the worm wheel, causing the fourth rotating shaft to rotate. This rotation, in turn, drives the connecting rod, which in turn moves the second connecting rod. The movement of the second connecting rod simultaneously pulls multiple sliders, causing them to slide within the limiting groove. The movement of these sliders, in turn, drives the third rotating shaft, causing the fourth roller to move. By adjusting the distance between the fourth rollers, the maximum diameter of the bearing ring after ring rolling can be limited before the ring rolling process. This also makes the device more stable during the ring rolling process.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 As shown, this utility model is a rolling device for preparing bearing rings, including an operating table 1. A bearing ring 101 is slidably connected to the top outer wall of the operating table 1. A positioning mechanism 2 is provided on the outer wall of the operating table 1. Through the provided roller 201, when the roller 201 rotates, it can drive the bearing ring 101 to rotate, which facilitates the subsequent rolling process of the bearing ring 101. Positioning mechanism 2 includes a roller 201. A drive shaft 202 is fixedly connected to the inner wall of the roller 201. A motor 203 is fixedly connected to the top outer wall of the drive shaft 202. A motor frame 204 is fixedly connected to the outer wall of the motor 203. A fixing block 205 is fixedly connected to the top outer wall of the operating table 1 near the roller 201. The motor frame 204 can fix the position of the motor 203 to prevent the motor 203 from shaking violently during operation. Several telescopic rods 206 are fixedly connected to the outer wall of the fixing block 205 near the bearing ring 101. Several springs 207 are fixedly connected to the outer wall of the telescopic rods 206 near the fixing block 205. The telescopic rods 206 are located away from the fixing block 205. A rotating shaft 208 is rotatably connected to the inner wall of one end of the spring 207. The telescopic rod 206 can support and limit the spring 207 to prevent the spring 207 from shaking violently during the extension and retraction process. A roller 209 is fixedly connected to the outer wall of the rotating shaft 208. A roller 210 is slidably connected to the inner wall of the bearing ring 101 away from the roller 201. A rotating shaft 211 is fixedly connected to the outer wall of the roller 210. A hydraulic cylinder 212 is rotatably connected to the outer wall of the rotating shaft 211. An auxiliary mechanism 3 is provided on the outer wall of the operating table 1. The hydraulic cylinder 212 can support and limit the rotating shaft 211. When the user starts the hydraulic cylinder 212, the hydraulic cylinder 212 shortens, which can drive the rotating shaft 211 to move, causing the roller 210 to move towards the hydraulic cylinder 212.

[0020] The outer wall of roller 201 is slidably connected to the inner wall of bearing ring 101. The outer walls of several springs 207 are fixedly connected to the outer wall of fixing block 205. The outer wall of roller 209 is slidably connected to the outer wall of bearing ring 101. The outer wall of hydraulic cylinder 212 is fixedly connected to the outer wall of operating platform 1. Auxiliary mechanism 3 includes several electric telescopic rods 301. The electric telescopic rods 301 can provide a certain support for connecting plate 302. After the ring rolling process is completed, the electric telescopic rods 301 are activated to lift the connecting plate 302 as a whole, so that bearing ring 101 can be removed. The outer walls of several electric telescopic rods 301 are fixedly connected to the inner wall of operating platform 1. A connecting plate 302 is fixedly connected to the bottom output end of the retractable rod 301. The outer wall of the connecting plate 302 is slidably connected to the inner wall of the operating table 1. The connecting plate 302 can fix the position of the motor frame 204 to prevent the motor frame 204 from shifting and causing the auxiliary mechanism 3 of 201 to shake. The outer wall of the connecting plate 302 is fixedly connected to the outer wall of the motor frame 204. Several limiting grooves 303 are provided on the inner wall of the connecting plate 302. A slider 304 is slidably connected to the inner wall of each limiting groove 303. The limiting groove 303 can limit the movement trajectory of the slider 304, so that it can only move linearly along the direction of the limiting groove 303 within the limiting groove 303.

[0021] A rotating shaft 305 is fixedly connected to the bottom outer wall of several sliders 304. Rollers 306 are rotatably connected to the outer wall of the rotating shaft 305. The outer walls of the rollers 306 are slidably connected to the outer wall of the bearing ring 101. A support block 307 is fixedly connected to the top outer wall of the connecting plate 302. The support block 307 supports and limits the worm 308, preventing it from disengaging from the worm wheel 310. The worm 308 is rotatably connected to the inner wall of the support block 307. A rotating shaft 309 is rotatably connected to the central axis of the top outer wall of the connecting plate 302 near the worm 308. The rotating shaft 309 is close to the worm 308. A worm gear 310 is fixedly connected to the outer wall of one end of the worm 308. The rotating shaft 309 can support the worm gear 310, so that the worm gear 310 can only rotate on the rotating shaft 309. The outer wall of the worm gear 310 meshes with the outer wall of the worm 308. A connecting rod 311 is fixedly connected to the outer wall of the rotating shaft 309. Several connecting rods 312 are rotatably connected to the outer wall of the connecting rod 311. The inner wall of the connecting rods 312 is rotatably connected to the outer wall of the slider 304. When the connecting rods 312 can transmit power to the slider 304, when the connecting rod 311 drives the connecting rods 312 to move, the movement of the connecting rods 312 will pull the slider 304 to slide in the limiting groove 303.

[0022] One specific application of this embodiment is: When the equipment is to be used, the calcined bearing ring 101 is first fixed between roller 201 and roller 209, and roller 210 is inserted into the bearing ring 101. Then, the motor 203 is started. The rotation of the motor 203 drives the drive shaft 202 to rotate, causing the roller 201 to rotate. Because roller 210 at the other end pulls the bearing ring 101 tight, and the spring 207 constantly compresses the rotating shaft 208 through its own elastic force, causing roller 209 to always press against the outer wall of the bearing ring 101, the rotation of roller 210 will drive the bearing ring 101 to rotate. At this time, the hydraulic cylinder 212 is started, causing the rotating shaft 211 and roller 210 to gradually move away from the roller 201. At this time, the bearing ring 101 will gradually expand under the pulling force of roller 210. Due to the interaction between roller 3 210, roller 201, and roller 209, the bearing ring 101 can always be rolled in the appropriate position to ensure the rolling accuracy. Before rolling, the worm 308 is rotated. The rotation of the worm 308 can drive the worm wheel 310 to rotate, causing the rotating shaft 4 309 to rotate. The rotation of the rotating shaft 4 309 can drive the connecting rod 311 to rotate. The rotation of the connecting rod 311 will drive the connecting rod 2 312 to move. When the connecting rod 2 312 moves, it will simultaneously pull multiple sliders 304 to slide within the limiting groove 303. When the sliders 304 move, they will drive the rotating shaft 305 to move, causing the roller 4 306 to move. By adjusting the distance between the rollers 4 306, the maximum diameter of the bearing ring 101 can be limited. At the same time, during the rolling process, the expansion process of the bearing ring 101 can be made smoother.
