Description

Technical Field

[0001] This utility model belongs to the field of bearing ring processing technology, and in particular relates to an end face grinding machine for bearing rings. Background Technology

[0002] According to the published patent CN218051736U, a bearing ring end face grinding device includes a machine body with an upper turntable and a lower turntable mounted on it. The machine body is equipped with drive mechanisms for rotating the upper and lower turntables respectively, and a dust removal assembly is also installed on the machine body. An upper grinding piece is mounted on the lower side of the upper turntable, allowing simultaneous grinding of both end faces of the workpiece. It can also grind workpieces of different specifications, effectively improving the efficiency of small-batch production. However, it still has the following shortcomings:

[0003] While the aforementioned equipment can grind both ends of bearing races, the simple fixing device may cause displacement of the bearing races during grinding. Furthermore, since the dimensions of the fixing device are fixed, it can only grind bearing races of the same diameter, reducing the applicability of the equipment. Therefore, we propose an end face grinder for bearing races. Utility Model Content

[0004] The purpose of this utility model is to provide an end face grinding machine for bearing rings. Through the positioning mechanism and disassembly mechanism, it solves the problems of the above-mentioned equipment, which can grind both ends of the bearing rings, but the bearing rings may shift during the grinding process due to the simple fixing device. In addition, since the size of the fixing device is fixed, it can only grind bearing rings of the same diameter, which reduces the applicability of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an end face grinding machine for bearing rings, including an operating table and bearing rings. A controller is fixedly connected to the outer wall of the operating table, and a positioning mechanism is provided on the inner wall of the operating table.

[0007] The positioning mechanism includes an electric telescopic rod. A rotating shaft is rotatably connected to the central axis of the inner wall of the operating platform near the electric telescopic rod. A rack is fixedly connected to the bottom output end of the electric telescopic rod. A gear is fixedly connected to the outer wall of the rotating shaft near the rack. An annular limiting block is fixedly connected to the outer wall of the rotating shaft away from the gear. Several limiting shafts are rotatably connected to the inner wall of the annular limiting block. A connecting rod is fixedly connected to the outer wall of each of the several limiting shafts. A second limiting shaft is fixedly connected to the inner wall of the connecting rod away from the limiting shaft. A clamping plate is rotatably connected to the outer wall of each of the several second limiting shafts. Several anti-slip grooves are formed on the inner wall of the clamping plate. Several limiting sliding grooves are formed on the inner wall of the operating platform near the clamping plate. A disassembly mechanism is provided on the outer wall of the operating platform.

[0008] Furthermore, the outer wall of the electric telescopic rod is fixedly connected to the inner wall of the operating table, the outer wall of the gear meshes with the outer wall of the rack, the inner walls of several clamping plates are slidably connected to the outer walls of the bearing rings, and the inner wall of the limiting groove is slidably connected to the outer walls of the clamping plates.

[0009] Furthermore, the disassembly mechanism includes several support frames, the outer walls of which are fixedly connected to the top outer wall of the operating table, and an electric telescopic rod is fixedly connected to the outer walls of which are also fixedly connected.

[0010] Furthermore, a motor is fixedly connected to the inner wall of each of the electric telescopic rods II, and a rotating shaft II is fixedly connected to the bottom output end of the motor via a coupling.

[0011] Furthermore, a limiting slide sleeve is fixedly connected to the outer wall of one end of the rotating shaft near the bearing ring, and a limiting slide rod is slidably connected to the inner wall of the limiting slide sleeve.

[0012] Furthermore, a spring is fixedly connected to the outer wall of the end of the limiting slide rod near the limiting slide rod sleeve, and the outer wall of the spring is fixedly connected to the outer wall of the limiting slide rod sleeve. A grinding disc is slidably connected to the outer wall of the end of the limiting slide rod away from the spring.

[0013] Furthermore, the inner wall of the grinding disc is provided with several mounting grooves, and the inner wall of the limiting slide rod near the mounting groove is rotatably connected to a threaded rod, and the outer wall of the threaded rod is threadedly connected to a connecting rod II.

[0014] Furthermore, the outer wall of the second connecting rod is rotatably connected to several locking blocks, and the inner wall of the limiting slide rod near the locking block is fixedly connected to several fixed shafts, and the inner wall of the locking block near the fixed shaft is provided with an arc-shaped groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a gear on a rotating shaft. When the equipment is needed, after grinding, the controller controls the electric telescopic rod to shorten it. The shortening of the electric telescopic rod drives the rack to move, which in turn drives the gear to rotate on the electric telescopic rod. The rotation of the electric telescopic rod drives the annular limit block to rotate, which in turn drives the limit shaft to rotate, thus pulling the connecting rod. This achieves the goal of positioning the bearing during the grinding of the bearing ring, preventing displacement or even detachment during subsequent grinding, which could lead to insufficient grinding accuracy or even grinding failure, thereby improving the grinding accuracy of the device.

[0017] 2. This utility model incorporates a spring on the limiting slide rod. During operation, rotating the threaded rod causes the fixed axis to move towards the limiting slide rod. The movement of the connecting rod then moves the locking block. Since the other end of the locking block is fixed to the fixed shaft via an arc groove, the block initially moves a straight line a short distance towards the limiting slide rod, then gradually converges towards the center along the arc groove. This ensures that when the bearing ring is being polished by the grinding disc, it remains firmly against the end face of the bearing ring, preventing loosening and polishing failure. Furthermore, when the grinding disc wears out after prolonged use and needs replacement, the device facilitates easy installation and removal without the need for additional tools, making it quite convenient.

[0018] 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

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 As shown, this utility model is an end face grinding machine for bearing rings, including an operating table 1 and a bearing ring 102. A controller 101 is fixedly connected to the outer wall of the operating table 1, and a positioning mechanism 2 is provided on the inner wall of the operating table 1. Through the controller 101, the user can freely control the start and stop of the electric telescopic rod 201, the electric telescopic rod 302, and the motor 303.

[0031] The positioning mechanism 2 includes an electric telescopic rod 201. A rotating shaft 202 is rotatably connected to the central axis of the inner wall of the operating platform 1 near the electric telescopic rod 201. A rack 203 is fixedly connected to the bottom output end of the electric telescopic rod 201. A gear 204 is fixedly connected to the outer wall of the rotating shaft 202 near the rack 203. Because the rack 203 and gear 204 mesh with each other, the rack 203 will drive the gear 204 to rotate when it moves, which in turn will drive the rotating shaft 202 to rotate. An annular limiting block 205 is fixedly connected to the outer wall of the rotating shaft 202 away from the gear 204. Several limiting shafts 206 are rotatably connected to the inner wall of the annular limiting block 205, and the outer walls of the several limiting shafts 206 are all fixedly connected to... Link 207 has a second limiting shaft 208 fixedly connected to the inner wall of the end of link 207 away from limiting shaft 206. Limiting shaft 206 can limit the position of link 207, so that it can only rotate on limiting shaft 206, preventing link 207 from falling. Clamping plates 209 are rotatably connected to the outer walls of several second limiting shafts 208. Several anti-slip grooves 210 are opened on the inner wall of clamping plates 209. Several limiting slide grooves 211 are opened on the inner wall of the end of operating table 1 near clamping plate 209. A disassembly mechanism 3 is provided on the outer wall of operating table 1. The movement trajectory of clamping plate 209 can be limited by the limiting slide grooves 211, so that it can only slide in a straight line along the direction of limiting slide groove 211.

[0032] The outer wall of the electric telescopic rod 201 is fixedly connected to the inner wall of the operating table 1. The outer wall of the gear 204 meshes with the outer wall of the rack 203. The inner walls of several clamping plates 209 are slidably connected to the outer wall of the bearing ring 102. The inner wall of the limiting groove 211 is slidably connected to the outer wall of the clamping plate 209. The disassembly mechanism 3 includes several support frames 301. The support frames 301 can support and limit the electric telescopic rod 302 to prevent the support frames 301 from tipping over. The outer walls of several support frames 301 are fixedly connected to the top outer wall of the operating table 1. The electric telescopic rod 302 is fixedly connected to the outer walls of several support frames 301. Motors 303 are fixedly connected to the inner walls of the device. When motors 303 are started, their rotation drives the second rotating shaft 304 to rotate, which in turn drives the limiting slide sleeve 305 to rotate. The bottom output end of motor 303 is fixedly connected to the second rotating shaft 304 via a coupling. The outer wall of the end of the second rotating shaft 304 near the bearing ring 102 is fixedly connected to the limiting slide sleeve 305. The inner wall of the limiting slide sleeve 305 is slidably connected to the limiting slide rod 306. The limiting slide sleeve 305 can limit the movement trajectory of the limiting slide rod 306, so that it can only slide in a straight line within the limiting slide sleeve 305, and at the same time, it can prevent the limiting slide rod 306 from slipping off.

[0033] A spring 307 is fixedly connected to the outer wall of the limiting slide rod 306 near the limiting slide rod sleeve 305. The outer wall of the spring 307 is fixedly connected to the outer wall of the limiting slide rod sleeve 305. A grinding disc 308 is slidably connected to the outer wall of the limiting slide rod 306 away from the spring 307. The limiting slide rod 306 can limit the movement trajectory of the spring 307 to prevent the spring 307 from breaking during extension and retraction. Several mounting grooves 309 are provided on the inner wall of the grinding disc 308. A threaded rod 310 is rotatably connected to the inner wall of the limiting slide rod 306 near the mounting groove 309. A connecting rod is threadedly connected to the outer wall of the threaded rod 310. Link 2 314 can limit the position of the locking block 311. At the same time, when link 2 314 moves, it will drive the locking block 311 to move as well. Several locking blocks 311 are rotatably connected to the outer wall of link 2 314. Several fixed shafts 313 are fixedly connected to the inner wall of the end of the limiting slide bar 306 near the locking block 311. An arc-shaped groove 312 is opened on the inner wall of the end of the locking block 311 near the fixed shaft 313. Since the fixed shaft 313 can only slide in the arc-shaped groove 312, the arc-shaped groove 312 can limit the movement trajectory of the locking block 311 so that it can only move along the direction of the arc-shaped groove 312.

[0034] One specific application of this embodiment is:

[0035] When the equipment is needed, the bearing ring 102 is fixed between multiple clamping plates 209. Then, the electric telescopic rod 302 is activated, causing the motor 303 to extend and retract towards the bearing ring 102, so that the grinding disc 308 is pressed against the two end faces of the bearing ring 102. Then, the motor 303 is activated, and the rotation of the motor 303 drives the rotating shaft 304 to rotate, which in turn drives the limiting slide sleeve 305 to rotate. The rotation of the limiting slide sleeve 305 drives the limiting slide 306 to rotate, and the limiting slide 306 rotates... The movement of the lever 311 causes the grinding disc 308 to rotate, grinding the end face of the bearing ring. After grinding, the controller 101 controls the electric telescopic rod 201 to shorten it. The shortening of the electric telescopic rod 201 causes the rack 203 to move, which in turn causes the gear 204 to rotate on the electric telescopic rod 201. The rotation of the electric telescopic rod 201 causes the annular limit block 205 to rotate, which in turn causes the limit shaft 206 to rotate, pulling the connecting rod 20. 7. When the connecting rod 207 moves, it drives the second limiting shaft 208 to move. The movement of the second limiting shaft 208 pulls the clamping plate 209 to slide within the limiting slide groove 211. When the clamping plate 209 gradually moves to both ends and loosens the bearing ring 102, the bearing ring 102 can be removed normally. If the grinding disc 308 wears out after long-term use and needs to be replaced, rotate the threaded rod 310 to drive the fixed shaft 313 to move closer to the limiting slide rod 306. When the connecting rod 214 moves, it drives the locking block 311 to move. The other end of the locking block 311 is fixed to the fixed shaft 313 by the arc groove 312. Therefore, when the locking block 311 moves in the direction of the limiting slide bar 306, it will first move in a straight line for a distance, and then gradually converge towards the middle for a distance along the bending direction of the arc groove 312. At this time, the locking block 311 will no longer be locked in the mounting groove 309, and the grinding disc 308 can be removed and replaced as a whole. The spring 307 can always squeeze the grinding disc 308 through its own elastic force so that it always sticks to the end face of the bearing ring during the grinding process.
