Description

Technical Field

[0001] The utility model relates to the technical field of bearing inner ring processing, in particular to a grinding device for bearing inner ring processing. Background Art

[0002] Bearings are key components in mechanical equipment, primarily used to support rotating shafts, reduce friction, and ensure precise rotational motion. There are many types of bearings, and they can be categorized into various types based on characteristics such as load-bearing direction, rolling element type, self-aligning capability, number of rolling element rows, and whether components can be separated. The machining of bearing inner rings typically requires high precision and surface quality, so grinding equipment is crucial in the bearing manufacturing process.

[0003] For example, a grinding device for processing bearing inner rings disclosed in Chinese patent CN212762590U realizes the selection of different grinding wheels according to different types of bearings through the threaded connection between the threaded column and the grinding wheel, and the coordinated use of the fixing hole, the fixing ring and the mold, thereby realizing the grinding of the inner rings of bearings of different types, solving the problem that the existing bearing grinding device grinds a relatively single type of bearings. The sliding groove and the slider are both T-shaped, which facilitates the guiding effect of the transmission box and achieves the stability of the transmission device during the descent process. The coordinated use of the transmission device drives the rotation of multiple grinding wheels, realizing the grinding of multiple bearing inner rings, solving the problem that the grinding of a single bearing takes time, resulting in increased time cost and reduced production efficiency.

[0004] Although this structure can grind multiple bearing inner rings simultaneously, the device is not convenient for clamping bearings of different sizes, resulting in inconvenience in stable grinding of bearings of different sizes. Therefore, we propose a grinding device for bearing inner ring processing that can clamp bearings of different sizes to make their grinding more stable. Utility Model Content

[0009] Preferably, the clamping plate is made of rubber material and is arranged in an arc surface. Under its limitation, the contact area between the clamping plate and the bearing body can be increased, and the clamping plate made of rubber material can increase the friction coefficient between the clamping plate and the bearing body, thereby stably clamping the bearing body.

[0010] Preferably, the limit blocks are slidingly arranged inside the processing table. There are three limit blocks, which are distributed around the center of the leak plate. When they are restricted by the three groups of limit blocks, when they move together, they drive the push block and the clamping plate to move accordingly, and quickly clamp the bearing body in the center.

[0011] Preferably, the first magnetic plate and the second magnetic plate magnetically repel each other, and the push plate is slidingly arranged inside the slide groove. Under its restriction, when the rotating column no longer rotates, the second magnetic plate can be pushed into the slide groove, causing the grinding brush to vibrate and shake off the debris attached to the inside of the grinding brush.

[0012] Preferably, there are six grinding brushes, which are distributed around the center of the rotating cylinder. Under these restrictions, the rotating grinding brushes can grind the bearing body.

At this time, the motor is started, and the rotating column fixedly installed at its output end rotates accordingly. Under the action of centrifugal force, the second magnetic plate sliding inside the slide groove is swung toward the outside of the slide groove, so that the second magnetic plate drives the push plate and the grinding brush to move, so that the grinding brush contacts the inner wall of the bearing body, thereby grinding the bearing. The inside of the body is ground. When the grinding is completed, the rotating column no longer rotates. Under the magnetic repulsion limit of the first magnetic plate and the second magnetic plate, the second magnetic plate is reset and pushed, so that the second magnetic plate drives the push plate to slide into the inside of the slide groove. At this time, the grinding brush generates a vibration force to vibrate the debris attached to the inside of the grinding brush. The operator does not need to clean the grinding brush. When the size of the bearing body is large, the rotating column speed is accelerated, and the part thrown out by the push plate is longer, so that the grinding brush contacts and grinds with the inner wall of the bearing body. This structure can grind bearing bodies of different sizes, and there is no need to frequently replace the grinding device due to different sizes of bearing bodies. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of a grinding device for machining a bearing inner ring provided by the present invention is as follows: Figures 1 to 6 Shown: A grinding device for machining a bearing inner ring, comprising a machining table 1;

[0025] The top surface of the processing table 1 is provided with a bearing body 3;

[0026] A debris removal mechanism 2 is provided on the outside of the bearing body 3;

[0027] And a processing component 4 is arranged outside the bearing body 3, the processing component 4 includes a clamping component 41 arranged outside the bearing body 3, the clamping component 41 includes a debris port 411 opened on the top surface of the processing table 1, a leak plate 412 is fixedly installed inside the debris port 411, a support plate 413 is arranged below the leak plate 412, a screw 414 is rotatably connected to the bottom of the support plate 413, a sleeve block 415 is sleeved on the outer wall of the screw 414, a connecting plate 416 is hinged on the outer wall of the sleeve block 415, and the connecting plate 416 is hinged to a limit block 417 at one end away from the sleeve block 415, a push block 418 is fixedly installed on the top surface of the limit block 417, and a clamping plate 419 is hinged on the end of the push block 418.

[0028] In this embodiment, when grinding the inner ring of the bearing body 3, it is necessary to clamp it first, place the bearing body 3 on the top surface of the leak plate 412, and rotate the screw 414. Since the limit block 417 is slidably connected to the groove body opened on the top surface of the processing table 1, and the end of the connecting plate 416 is hinged to the sleeve block 415 and the limit block 417, when the screw 414 is rotated, the sleeve block 415 can move downward, and the sleeve block 415 pulls the limit block 417 through the connecting plate 416, so that the three limit blocks 417 move together, and the limit block 417 drives the push block 418 The clamping plate 419 moves accordingly, so that the clamping plate 419 contacts the outer wall of the bearing body 3 and clamps the bearing body 3. This structure can quickly clamp the bearing body 3 and can clamp bearing bodies 3 of different sizes. When the bearing body 3 is not placed at the center of the leak plate 412, it can be pushed against the outer wall of the bearing body 3 under the restriction of the hinged clamping plate 419. When the bearing body 3 produces debris during grinding, it can fall through the leak plate 412 to prevent the debris from accumulating on the top surface of the processing table 1, thereby affecting the grinding effect of the bearing body 3.

[0029] Furthermore, the clamping plate 419 is made of rubber and is set in an arc surface. Under its limitation, the contact area between the clamping plate 419 and the bearing body 3 can be increased, and the clamping plate 419 made of rubber can increase the friction coefficient between the clamping plate 419 and the bearing body 3, thereby stably clamping the bearing body 3.

[0030] Furthermore, the limit block 417 is set to slide inside the processing table 1. There are three limit blocks 417, which are distributed around the center of the leak plate 412. Under the restriction of the three groups of limit blocks 417, when they gather together, they drive the push block 418 and the clamping plate 419 to move accordingly, and quickly clamp the bearing body 3 in the center.

[0031] Example 2: Based on Example 1, a preferred embodiment of a grinding device for machining a bearing inner ring provided by the present invention is as follows: Figures 1 to 6 As shown: the grinding assembly 42 includes a slide rod 421 fixedly mounted on the top surface of the processing table 1, a slide plate 422 is slidingly provided on the outer wall of the slide rod 421, a telescopic rod 423 is fixedly mounted on the bottom of the slide plate 422, a mounting plate 424 is provided on the side of the slide plate 422 away from the telescopic rod 423, a motor 425 is fixedly mounted on the bottom of the mounting plate 424, a rotating rod 426 is fixedly mounted on the output end of the motor 425, a rotating column 427 is fixedly mounted on the end of the rotating rod 426, a sliding groove 428 is provided on the outer wall of the rotating column 427, a first magnetic plate 429 is fixedly mounted on the inner wall of the sliding groove 428, a second magnetic plate 430 is slidingly provided inside the sliding groove 428, a push plate 431 is fixedly mounted on the side wall of the second magnetic plate 430, and a grinding brush 432 is fixedly mounted on the end of the push plate 431 away from the second magnetic plate 430.

[0032] In this embodiment, when it is necessary to grind the clamped bearing body 3, the telescopic rod 423 is started, which drives the slide plate 422 to slide on the outer wall of the slide rod 421 and move downward, so that the slide plate 422 drives the mounting plate 424 and the motor 425 to move accordingly, so that the rotating rod 426 fixedly installed at the output end of the motor 425 is sleeved inside the bearing body 3. At this time, the motor 425 is started, and the rotating column 427 fixedly installed at its output end rotates accordingly. Under the action of centrifugal force, the second magnetic plate 430 slidingly arranged inside the slide groove 428 is swung toward the outside of the slide groove 428, so that the second magnetic plate 430 drives the push plate 431 and the grinding brush 432 to move, so that the grinding brush 432 contacts the inner wall of the bearing body 3, and grinds the inside of the bearing body 3. During the grinding process, when the grinding is completed, the rotating column 427 stops rotating. Under the restriction of the magnetic repulsion between the first magnetic plate 429 and the second magnetic plate 430, the second magnetic plate 430 is reset and pushed, so that the second magnetic plate 430 drives the push plate 431 to slide into the inside of the slide groove 428. At this time, the grinding brush 432 generates a vibration force to vibrate the debris attached to the inside of the grinding brush 432. The operator does not need to clean the grinding brush 432. When the size of the bearing body 3 is larger, the rotation speed of the rotating column 427 is accelerated, and the part thrown out by the push plate 431 is longer, so that the grinding brush 432 contacts and grinds with the inner wall of the bearing body 3. This structure can grind bearing bodies 3 of different sizes, and there is no need to frequently replace the grinding device due to the different sizes of the bearing body 3.

[0033] Furthermore, the first magnetic plate 429 and the second magnetic plate 430 magnetically repel each other, and the push plate 431 is slidingly arranged inside the slide groove 428. Under its restriction, when the rotating column 427 no longer rotates, the second magnetic plate 430 can be pushed into the slide groove 428, causing the grinding brush 432 to vibrate and shake off the debris attached to the inside of the grinding brush 432.

[0034] In addition, there are six grinding brushes 432 , which are distributed around the center of the rotating column 427 . Under the restriction of the rotating grinding brushes 432 , the rotating grinding brushes 432 can grind the bearing body 3 .

[0035] The above is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention. It should also be noted that the various components of the present invention are not limited to the above-mentioned overall application. The various technical features described in the specification of the present invention can be selected for use alone or in combination according to actual needs. Therefore, the present invention naturally covers other combinations and specific applications related to the utility model points of this case.
