[0015] A cleaning method for a bearing processing cleaning device comprises the following steps:

[0016] S1. Loading of bearing rings: First, roughly place the outer ring of the bearing in the fixed groove manually, and then place the inner ring of the bearing on the inner side of the outer ring of the bearing through the fixed arm with limited claws;

[0017] S2. Positioning: the inner ring of the bearing placed by the fixing arm can be placed exactly at the center of the fixing groove. When the fixing arm is pressed down, the position of the outer ring of the bearing is adjusted by the positioning assembly so that it is concentric with the inner ring of the bearing;

[0018] S3. Adjust the bearing outer ring cleaning mechanism, and the piston rod of the electric push rod returns to its original position, so that the limit claw releases the restriction on the bearing inner ring. Driven by the piston rod of the electric push rod, the extended protrusion contacts the guide block, thereby causing the rack to move. Driven by the rack, the second connecting rod rotates, so that the second cleaning brush head originally facing the bearing inner ring faces the bearing outer ring;

[0019] S4, cleaning, by adjusting the motor to drive the fixed arm to rotate, during the rotation process, the bearing outer ring cleaning mechanism is used to clean the raceway on the inner side of the bearing outer ring, and the bearing inner ring cleaning mechanism is used to clean the raceway on the outer side of the bearing inner ring;

[0020] S5, eccentric adjustment. After cleaning, the fixed arm returns to its original position and rises. Driven by the fixed arm, the lever contacts the outer ring of the bearing, thereby causing the outer ring of the bearing to be eccentric to the inner ring of the bearing.

[0021] The present invention has the following beneficial effects:

[0022] 1. A bearing processing cleaning device and a cleaning method thereof can fix and transport the inner ring of the bearing by setting a fixed arm with a limiting claw. After the inner ring of the bearing is loaded, it is only necessary to start the adjusting motor. Under the drive of the adjusting motor, the fixed arm reciprocates, and the bearing outer ring cleaning mechanism and the bearing inner ring cleaning mechanism rotate synchronously with the fixed arm. The raceway on the inner side of the bearing outer ring can be cleaned by the second cleaning brush head and the second nozzle on the bearing outer ring cleaning mechanism, and the raceway on the outer side of the bearing inner ring can be cleaned by the first cleaning brush head and the first nozzle on the bearing inner ring cleaning mechanism. The present invention can quickly complete the cleaning of the inner and outer rings of the bearing during the process of placing the inner ring of the bearing by setting a fixed arm with a bearing outer ring cleaning mechanism, a bearing inner ring cleaning mechanism and a limiting claw, thereby greatly improving the processing efficiency.

[0023] 2. A cleaning device for bearing processing and a cleaning method thereof, wherein a bearing outer ring fixing seat with a positioning assembly is provided, wherein the positioning assembly mainly comprises a positioning rod, a first transmission plate, a second transmission plate and an adjustment seat, and correspondingly, a top head is also provided on the fixing arm. When loading, the fixing arm places the bearing inner ring in the fixing groove from top to bottom. During its movement, the top head contacts the adjustment seat to press the adjustment seat downward. With the movement of the adjustment seat, the adjustment seat contacts the second transmission plate, thereby pushing the second transmission plate to move. One end of the second transmission plate contacts the first transmission plate, thereby pushing the first transmission plate to deflect. The other end of the first transmission plate contacts the positioning rod. Under the push of the first transmission plate, the positioning rod overcomes the resistance of the rebound spring and moves into the fixing groove. During this process, the positioning rod contacts the outer peripheral portion of the bearing outer ring in the fixing groove, thereby achieving the purpose of adjusting the position of the bearing outer ring.

[0024] The present invention arranges a positioning component on the bearing outer ring fixing seat, so that in the initial stage of loading, the operator does not need to accurately place the workpiece in the fixing groove, which greatly reduces the loading difficulty and improves the loading efficiency.

[0025] 3. The cleaning equipment and cleaning method for bearing processing are provided with a second connecting rod with a lever. When loading, the limit claw extends out to press against the inner ring of the bearing. When loading is completed, the telescopic rod of the electric push rod returns to its original position. During this process, the limit claw retracts into the fixed arm. At the same time, as the extension protrusion contacts with the guide block, the guide block moves with the rack under the push of the extension protrusion. As the rack moves, the second connecting rod rotates, so that the second cleaning brush head faces the outer ring of the bearing. In this way, as the fixed arm rotates, the outer ring of the bearing can be cleaned by the second cleaning brush head. After cleaning is completed, the fixed arm rises and returns to its position. During this process, the lever contacts with the outer ring of the bearing. Under the push of the lever, the outer ring of the bearing is eccentric with the inner ring of the bearing.

[0026] The present invention provides a second connecting rod with a lever, and after cleaning is completed, the inner ring and the outer ring of the bearing can be automatically adjusted to the eccentric device, so that subsequent assembly work becomes simpler. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figures 1 to 6A bearing processing cleaning device comprises a frame 1, a conveyor belt 2 is arranged on the frame 1, a fixed arm 3 is arranged on one side of the frame 1, and a fixed cross bar 4 is arranged on the fixed arm 3, a bearing inner ring cleaning mechanism is arranged at one end of the fixed cross bar 4, and a bearing outer ring cleaning mechanism is arranged at the other end of the fixed cross bar 4, comprising a first connecting rod 5, a first cleaning brush head 501 is arranged on the first connecting rod 5, and first nozzles 502 are arranged on both sides of the first cleaning brush head 501;

[0036] The bearing outer ring cleaning mechanism comprises a second connecting rod 6, which is rotatably connected to the fixed cross bar 4, and a second cleaning brush head 601 is provided on the second connecting rod 6, and second nozzles 602 are provided on both sides of the second cleaning brush head 601;

[0037] The conveyor belt 2 is provided with a bearing outer ring fixing mechanism, and the bearing outer ring fixing mechanism includes a bearing outer ring fixing seat 7, a fixing groove 701 is provided in the middle of the bearing outer ring fixing seat 7, and the bearing outer ring fixing seat 7 is provided with a plurality of positioning components for positioning the bearing outer ring.

[0038] A top head 301 is provided at one end of the fixed arm 3 , and a plurality of limit claws 8 are provided on the fixed arm 3 . The limit claws 8 are elastically connected to the fixed arm 3 through a second spring 9 , and the limit claws 8 are distributed on the fixed arm 3 .

[0039] By providing a fixed arm 3 with a bearing outer ring cleaning mechanism and a bearing inner ring cleaning mechanism, the cleaning of the bearing inner ring and the bearing outer ring raceway can be completed during the loading and unloading process of the bearing inner ring, which is more convenient to use. Specifically, a plurality of limit claws 8 are provided on the fixed arm 3. Under normal circumstances, the limit claws 8 are retracted into the fixed arm 3. When it is necessary to move the bearing inner ring to the bearing outer ring fixing seat 7, it is only necessary to insert the fixed arm 3 into the bearing inner ring, and then the electric push rod 10 works. Under the push of the electric push rod 10, the limit claws 8 extend from the fixed arm 3 and then contact the bearing inner ring. Under the action of the limit claws 8, the bearing inner ring is fixed to the fixed arm 3, and then the fixed arm 3 moves with the bearing inner ring to the top of the bearing outer ring fixing seat 7, and then the fixed arm 3 moves downward. When the specified position is reached, the electric push rod 10 returns to its position, and the limit claws 8 return to their original position under the pull of the second spring 9. After losing the restriction of the limit claws 8, the bearing inner ring is separated from the fixed arm 3;

[0040] Subsequently, the fixed arm 3 reciprocates under the drive of the adjusting motor 18, and the bearing outer ring cleaning mechanism and the bearing inner ring cleaning mechanism rotate synchronously with the fixed arm 3. The shapes of the first cleaning brush head 501 and the second cleaning brush head 601 are both consistent with the cross-section of the ball raceway. The second cleaning brush head 601 and the second nozzle 602 on the bearing outer ring cleaning mechanism can clean the raceway on the inner side of the bearing outer ring, and the first cleaning brush head 501 and the first nozzle 502 on the bearing inner ring cleaning mechanism can clean the raceway on the outer side of the bearing inner ring.

[0041] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 6 The positioning assembly includes a positioning rod 702, a first transmission plate 703, and a second transmission plate 704. The positioning rod 702 is elastically connected to the bearing outer ring fixing seat 7 through a rebound spring 705. The first transmission plate 703 is rotatably connected to the bearing outer ring fixing seat 7, and one end of the first transmission plate 703 is in contact with the positioning rod 702. The second transmission plate 704 is slidably connected to the bearing outer ring fixing seat 7, and one end of the second transmission plate 704 is in contact with the first transmission plate 703.

[0042] An adjustment seat 706 is provided in the fixing groove 701 , and the adjustment seat 706 is elastically connected to the bearing outer ring fixing seat 7 through a first spring 707 , and one end of the adjustment seat 706 abuts against the second transmission plate 704 , and a slope is provided on one side of the second transmission plate 704 close to the adjustment seat 706 .

[0043] In order to improve the feeding efficiency of the bearing outer ring, the present application sets a fixing groove 701 on the bearing outer ring fixing seat, and the fixing groove 701 is interference fit with the bearing outer ring. Therefore, when loading, the operator only needs to roughly place the bearing outer ring in the fixing groove 701. When cleaning, in order to reduce the cleaning dead angle, the bearing inner ring and the bearing outer ring are preferably kept in a concentric state. Therefore, the present application also sets a positioning component for adjusting the position of the bearing outer ring at the bearing outer ring fixing seat 7. The positioning component mainly includes a positioning rod 702, a first transmission plate 703, a second transmission plate 704 and an adjustment seat. Correspondingly, a head 301 is also provided on the fixed arm 3. When loading, the fixed arm 3 places the bearing inner ring on the fixed seat from top to bottom. In the groove 701, during its movement, the top head 301 conflicts with the adjustment seat 706, pressing the adjustment seat 706 downward, and as the adjustment seat 706 moves, the adjustment seat 706 conflicts with the second transmission plate 704, thereby pushing the second transmission plate 704 to move, and one end of the second transmission plate 704 conflicts with the first transmission plate 703, thereby pushing the first transmission plate 703 to deflect, and the other end of the first transmission plate 703 conflicts with the positioning rod 702. Under the push of the first transmission plate 703, the positioning rod 702 overcomes the resistance of the rebound spring 705 and moves into the fixed groove 701. In this process, the positioning rod 702 conflicts with the outer periphery of the bearing outer ring in the fixed groove 701, thereby achieving the purpose of adjusting the position of the bearing outer ring.

[0044] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 6 The fixed arm 3 is a hollow structure, and an electric push rod 10 for adjusting the limiting claw 8 is arranged inside the fixed arm 3 . A triangular protrusion 801 is arranged at one end of the limiting claw 8 close to the electric push rod 10 .

[0045] A rack 11 is provided inside the fixed cross bar 4, and the rack 11 is elastically connected to the fixed cross bar 4 through a third spring 12. A guide block 13 is provided at one end of the rack 11 away from the second connecting rod 6, and the second connecting rod 6 is meshed with the rack 11 through a gear.

[0046] An extension protrusion 14 is provided on the piston rod of the electric push rod 10 , and the position of the extension protrusion 14 corresponds to the position of the guide block 13 .

[0047] The second connecting rod 6 is rotatably connected to the fixed cross rod 4 via a bearing, and a shifting rod 15 is provided on the second connecting rod 6 , and the shifting rod 15 is located at the center of the second cleaning brush head 601 .

[0048] A lifting component for driving the fixed arm 3 to lift and lower is also provided on one side of the frame 1, and the lifting component includes a support frame 17, one end of the support frame 17 is rotatably connected to the frame 1, and a movable rod 19 is provided on the support frame 17, a lifting cylinder 16 is provided on one side of the support frame 17, and the piston rod of the lifting cylinder 16 is fixedly connected to the movable rod 19, the movable rod 19 is L-shaped, and an adjusting motor 18 is provided on the movable rod 19, and the output shaft of the adjusting motor 18 is fixedly connected to the fixed arm 3, and a driving motor 20 for driving the support frame 17 to rotate is provided on the frame 1.

[0049] During the bearing processing, the bearing needs to be assembled after the cleaning of all parts is completed. The general assembly process is to place the inner ring and the outer ring of the bearing together first, and then adjust the position of the inner ring and the outer ring of the bearing to make it as eccentric as possible, then put the ball into the gap between the inner ring and the outer ring of the bearing, and then adjust the position of the inner ring and the outer ring of the bearing to make it concentric, and then separate the balls through the ball separator, and finally install the retaining frame. The present application provides a second connecting rod 6 with a lever 15, which can automatically adjust the inner ring and the outer ring of the bearing to the eccentric device after cleaning, so that the subsequent assembly work becomes simpler. Specifically, the second connecting rod 6 can be rotated, and when the limit claw 8 is in the extended state In the state, the second cleaning brush head 601 and the lever 15 are facing the inner ring of the bearing. When the loading is completed, the telescopic rod of the electric push rod 10 returns to its original position. During this process, the limit claw 8 retracts into the fixed arm 3. At the same time, as the extending protrusion 14 contacts with the guide block 13, the guide block 13 moves with the rack 11 under the push of the extending protrusion 14. With the movement of the rack 11, the second connecting rod 6 rotates, so that the second cleaning brush head 601 faces the outer ring of the bearing. In this way, as the fixed arm 3 rotates, the outer ring of the bearing can be cleaned by the second cleaning brush head 601. After cleaning is completed, the fixed arm 3 rises and returns to its original position. During this process, the lever 15 contacts with the outer ring of the bearing. Under the push of the lever 15, the outer ring of the bearing and the inner ring of the bearing are eccentric.

[0050] The reason why a rotatable second connecting rod 6, a second cleaning brush head 601 and a lever 15 are provided is that the position of the outer ring of the bearing cannot be determined during the loading process. Therefore, in the process of the fixed arm 3 moving from top to bottom, it is easy for the lever 15 to conflict with the outer ring of the bearing. When this happens, it is easy to cause damage to the lever 15. Therefore, the present invention provides a rotatable second connecting rod 6, a second cleaning brush head 601 and a lever 15. When the second cleaning brush head 601 and the lever 15 reach the predetermined position, the lever 15 rotates, so that the lever 15 will avoid the outer ring of the bearing during the descent. At the same time, in the process of the fixed arm 3 driving the inner ring of the bearing to move, the lever 15 is located in the raceway outside the inner ring of the bearing, which can play a limiting role on the inner ring of the bearing, and can cooperate with the limiting claw 8 to better fix the inner ring of the bearing.

[0051] A cleaning method for a bearing processing cleaning device comprises the following steps:

[0052] S1. Loading the bearing ring: first, roughly place the outer ring of the bearing in the fixing groove 701 manually, and then place the inner ring of the bearing on the inner side of the outer ring of the bearing by the fixing arm 3 with the limiting claw 8;

[0053] S2, positioning, the inner ring of the bearing placed by the fixing arm 3 can be placed exactly at the center of the fixing groove 701, and when the fixing arm 3 is pressed down, the position of the outer ring of the bearing is adjusted by the positioning assembly so that it is concentric with the inner ring of the bearing;

[0054] S3, adjusting the bearing outer ring cleaning mechanism, the piston rod of the electric push rod 10 returns to its original position, prompting the limit claw 8 to release the restriction on the bearing inner ring, and the extended protrusion 14 is driven by the piston rod of the electric push rod 10 to contact the guide block 13, thereby prompting the rack 11 to move, and the second connecting rod 6 is driven by the rack 11 to rotate, so that the second cleaning brush head 601 originally facing the bearing inner ring is directed toward the bearing outer ring;

[0055] S4, cleaning, by adjusting the motor 18 to drive the fixed arm 3 to rotate, during the rotation process, the bearing outer ring cleaning mechanism is used to clean the raceway on the inner side of the bearing outer ring, and the bearing inner ring cleaning mechanism is used to clean the raceway on the outer side of the bearing inner ring;

[0056] S5, eccentric adjustment. After cleaning is completed, the fixed arm 3 returns to its original position and rises. Driven by the fixed arm 3, the lever 15 contacts the outer ring of the bearing, thereby causing the outer ring of the bearing to be eccentric with the inner ring of the bearing.

[0057] The present application skillfully combines the cleaning of the bearing assembly with the assembly of the bearing assembly, thereby not only greatly improving the cleaning efficiency of the bearing assembly, but also effectively improving the assembly efficiency of the bearing assembly.

[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
