Description

Technical Field

[0001] This invention relates to the field of bearing ball machining technology, specifically to a grinding equipment for machining high-precision bearing balls. Background Technology

[0002] Bearing balls, also known as bearing steel balls or rolling elements, are the core components of rolling bearings. They are wear-resistant transmission elements with a standard spherical shape installed between the inner and outer raceways of the bearing. They are usually made of high-strength, high-hardness materials with excellent wear resistance, such as ceramics and stainless steel. Their main function is to convert the sliding friction between the inner and outer rings of the bearing into rolling friction during operation. By rolling themselves, they reduce transmission resistance, while evenly distributing radial and axial loads, ensuring the bearing's rotational accuracy, improving transmission efficiency, and extending the overall service life of the bearing.

[0003] Existing ball grinding equipment for processing bearings typically uses a vibratory feeder to transport the balls to the processing station for grinding. Separate feed and discharge tracks are used to transport the balls before and after processing. If the balls are not sized correctly, they must be placed back on the vibratory feeder for secondary processing. This not only results in poor processing efficiency but also increases the workload for workers. Therefore, we now offer a ball grinding equipment for processing high-precision bearing balls, which eliminates the drawbacks of existing devices. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0045] In one embodiment, such as Figures 1-7As shown, a high-precision bearing ball grinding equipment includes a main body 1. A fixed universal joint 11 is installed at one end of the main body 1. A support plate 10 is fixedly connected to one end of the fixed universal joint 11. The support plate 10 is located inside the main body 1. A fixed plate 9 is installed at the end of the support plate 10 away from the fixed universal joint 11. A grinding turntable 8 is provided at the end of the fixed plate 9 away from the support plate 10. A transmission plate 7 is fixedly connected to the end of the grinding turntable 8 away from the fixed plate 9. A conveying mechanism for conveying the balls before and after processing is provided on the main body 1.

[0046] The conveying mechanism includes: a support frame 207 installed at one end of the main body 1 of the equipment, a vibratory plate 205 fixedly connected to the top of the support frame 207, the vibratory plate 205 being located on one side of the fixed universal assembly 11, a feed chute 202 being provided on the side of the fixed plate 9 and the support plate 10 near the vibratory plate 205, the bottom of the inner wall of the feed chute 202 being inclined, and a vibration motor 208 being installed at the bottom of the support frame 207;

[0047] The main body 1 of the equipment is equipped with a pushing mechanism for precisely pushing the transmission disc 7;

[0048] In this embodiment, it should be noted that the main body 1 of the equipment is equipped with a conveying component for conveying coolant, which can cool the ball bearings.

[0049] When in use, the ball bearings are placed in the inner cavity of the vibratory feeder 205. At this time, the push mechanism can drive the drive motor 6 and the transmission shaft to move stably. At the same time, the grinding turntable 8 is moved synchronously under the drive of the transmission shaft through the transmission disc 7 until the grinding turntable 8 moves to the appropriate position. This allows for convenient adjustment of the position of the grinding turntable 8.

[0050] Then, the ball can be conveyed to the grinding turntable 8 and the fixed plate 9 through the conveying mechanism. At the same time, the drive motor 6 is started to drive the grinding turntable 8 to rotate through the transmission shaft and transmission plate 7. At this time, the grinding turntable 8 performs grinding operation on the ball through the groove at the end and drives the ball to move. During this process, the waste generated by grinding falls into the inner cavity of the waste recycling tray 12 under the action of gravity and coolant, so as to collect the waste.

[0051] When the ball separates from the outer wall of the fixed plate 9, the ball moves to the inner cavity of the vibratory plate 205 under the action of gravity through the conveying mechanism. This allows the ball to be recycled after grinding. Repeating the above operation ensures that the ball is processed to a qualified state.

[0052] In one embodiment, such as Figures 1-7 As shown, the conveying mechanism includes: a first guide assembly disposed on the vibratory feeder 205;

[0053] The first guide assembly includes: a second guide frame 206 fixedly connected to one end of the vibratory feeder 205, the second guide frame 206 contacting the outer wall of one end of the support plate 10, the second guide frame 206 being located at one end of the feed trough 202, and a partition 204 fixedly connected inside the vibratory feeder 205, the partition 204 being located at one end port of the second guide frame 206;

[0054] The vibratory feeder 205 is equipped with a second guide assembly for recovering the balls;

[0055] The second guide assembly includes: a first guide frame 203 fixedly connected to the top of one end of the vibratory feeder 205. The first guide frame 203 is spiral in shape and is located above the second guide frame 206. The first guide frame 203 is fixedly connected to the partition plate 204. A discharge frame 201 is fixedly connected to the end of the first guide frame 203 away from the vibratory feeder 205. The discharge frame 201 is inclined in shape and is located inside the feed trough 202. Through the cooperation of the first guide assembly and the second guide assembly, the balls before and after grinding can be individually fed and discharged.

[0056] In one embodiment, such as Figures 2-4 As shown, the push organizations include:

[0057] A movable component mounted on the main body 1 of the device;

[0058] The moving component includes: a bearing seat 307 disposed above the main body 1, the bearing seat 307 being located at the end of the transmission disk 7 away from the grinding turntable 8, a pusher frame 302 being fixedly connected to the outer wall of the bearing seat 307, a drive motor 6 being installed at the end of the bearing seat 307 away from the transmission disk 7, a drive shaft being fixedly connected to the end of the transmission disk 7 away from the grinding turntable 8, the bearing seat 307 being rotatably sleeved on the outer wall of the drive shaft, the drive shaft being driven by the output end of the drive motor 6, a dust cover 5 being disposed at the top of the main body 1, the dust cover 5 being fixedly connected to the bearing seat 307, the pusher frame 302 being located inside the dust cover 5, a control panel 4 being installed at one end of the main body 1, the control panel 4 being located on one side of the dust cover 5, a waste recycling tray 12 being disposed inside the main body 1, the waste recycling tray 12 extending through to the outside of one end of the main body 1, and the waste recycling tray 12 being located below the fixed universal assembly 11;

[0059] The main body 1 of the equipment is equipped with a pusher component for pushing the pusher frame 302 to move back and forth;

[0060] The pusher frame 302 is provided with a limiting component for limiting the movement of the pusher frame 302;

[0061] The pushing component includes: two guide rods 305 symmetrically arranged above the main body 1 of the equipment; a support sleeve 306 is rotatably sleeved on the outer wall of the two guide rods 305 near the transmission disk 7; the support sleeve 306 is fixedly connected to the main body 1 of the equipment; a pushing frame 302 is located between the two guide rods 305; a moving block 304 is provided on the outer wall of the two guide rods 305; the moving block 304 is fixedly connected to the pushing frame 302.

[0062] A drive component is provided on the main body 1 of the device;

[0063] The drive assembly includes two servo motors 303 symmetrically arranged above the main body 1 of the equipment. Both servo motors 303 are fixedly connected to the main body 1 of the equipment via a mounting bracket. The two servo motors 303 are located at the ends of the two guide rods 305 away from the transmission disk 7. The two guide rods 305 are driven by the output ends of the two servo motors 303. Through the cooperation of the moving assembly, the pushing assembly and the drive assembly, the grinding turntable 8 can be moved precisely to the designated position.

[0064] In one embodiment, such as Figures 2-4 As shown, the limiting component includes two guide rails 301 symmetrically fixedly connected to the bottom of the pusher frame 302. The outer walls of the two guide rails 301 are slidably fitted with connecting slides. The main body of the equipment 1 is fixedly connected to the connecting slides. Through the mutual cooperation between the guide rails 301 and the connecting slides, the movement of the pusher frame 302 can be limited.

[0065] The above embodiments disclose a grinding equipment for processing high-precision bearing ball bearings. In use, the ball bearings are placed in the inner cavity of the vibratory plate 205. At this time, two servo motors 303 are started to drive the guide rod 305 to move the moving block 304. Simultaneously, the pusher frame 302, driven by the moving block 304, slides along the inner wall of the connecting slide via the guide rail 301. At this time, the bearing seat 307, driven by the pusher frame 302, drives the drive motor 6 and the transmission shaft to move stably. At the same time, the grinding turntable 8 moves synchronously through the transmission plate 7 driven by the transmission shaft until the grinding turntable 8 moves to a suitable position. This allows for convenient adjustment of the position of the grinding turntable 8.

[0066] Then, the vibration motor 208 is started to make the vibratory plate 205 vibrate slightly. At this time, the balls in the inner cavity of the vibratory plate 205 are moved along the inner wall of the second guide frame 206, the partition plate 204, and the feed chute 202 under the vibration conveying of the vibratory plate 205 to the grinding turntable 8 and the fixed plate 9. At the same time, the drive motor 6 is started to drive the grinding turntable 8 to rotate through the transmission shaft and the transmission plate 7. At this time, the grinding turntable 8 performs grinding operation on the balls through the groove at the end and drives the balls to move until the balls move to the top of the discharge frame 201. During this process, the waste generated by grinding falls into the inner cavity of the waste recycling tray 12 under the action of gravity and coolant, so as to collect the waste.

[0067] When the ball separates from the outer wall of the fixed plate 9, the ball comes into contact with the inner wall of the discharge frame 201 under the action of gravity. Then the ball rolls along the inner wall of the discharge frame 201 and the first guide frame 203 into the inner cavity of the vibratory plate 205. This allows the ball to be recycled after grinding. Repeating the above operation ensures that the ball in the inner cavity of the vibratory plate 205 is processed to a qualified state.

[0068] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
