Description

Technical Field

[0001] The present invention belongs to the technical field of bearing ring processing and grinding, and particularly relates to a grinding processing device for thin-walled bearings that prevents deformation. Background Art

[0002] During the production process of bearings, the inner walls of some bearings are designed to be conical to match the ends of the rotating shafts. This not only enables the bearings to horizontally limit the rotating shafts when clamped at the ends of the rotating shafts, but also, by grinding a conical surface on the inner wall of the bearing ring, the contact area between the bearing ring and the connecting piece can be increased, thereby further enhancing the stability of the rotating shaft.

[0003] However, during the grinding process of the bearing ring, as the grinding progresses, the thickness of the inner wall of the bearing ring continuously decreases, and the connection tightness between the grinding piece and the bearing ring decreases. At the same time, as the grinding continues, the contact area between the grinding piece and the inner wall of the bearing ring increases, and at this time, more debris is produced. The debris is easily thermally adhered to the grinding surface and the inner wall of the bearing ring, resulting in an increase in abnormal vibration during the grinding of the bearing ring, causing the bearing ring to shift and affecting the grinding accuracy of the bearing ring.

Specific implementation manners

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0041] As Figures 1-9 shown, a thin-wall bearing grinding and processing device for preventing deformation provided by the present invention includes a workbench 1. A moving frame 2 is slidably connected to the upper end surface of the workbench 1. A power component 10 for driving the moving frame 2 to slide horizontally is arranged on the workbench 1. The power component 10 consists of a motor and a threaded shaft. The threaded shaft is fixedly connected to the output shaft of the motor. The motor drives the threaded shaft to rotate. The threaded shaft drives the moving frame 2 to move horizontally along the end surface of the workbench 1 through screw transmission. A sleeve 16 is rotatably connected to the moving frame 2. A second driving component 11 for driving the sleeve 16 to rotate is arranged on the moving frame 2. The other end of the sleeve 16 far from the second driving component 11 is rotatably connected to a plurality of grinding rollers 14. Third electric rods 15 are rotatably connected between the grinding rollers 14 and the side end surface of the sleeve 16. The sleeve 16 can be connected to an external water pipe, and an adjusting component 3 for controlling the water spraying area is arranged at one end of the sleeve 16 close to the grinding rollers 14. Limiting components 4 for limiting the ports of the bearing rings are arranged on the grinding rollers 14;

[0042] A fixed frame 12 is fixedly arranged on the workbench 1 at a position opposite to the moving frame 2. Connecting frames 13 are fixedly connected to the side walls on both sides of the fixed frame 12. Clamping mechanisms 7 for radially limiting the bearing rings are fixedly connected to the connecting frames 13. The bearing rings can move along the axis of the sleeve 16 under the clamping of the clamping mechanisms 7;

[0043] A thrust component 5 for limiting one end of the bearing ring is provided on the fixing frame 12. The thrust component 5 can adjust the abutting force between the bearing ring and the grinding roller 14 in a telescopic movement manner. A positioning component 6 capable of adjusting the position and posture of the bearing ring is further provided on the thrust component 5. A cleaning mechanism 8 for cleaning the inner wall of the bearing ring is connected to the fixing frame 12. The cleaning mechanism 8 is connected to a filtering mechanism 9 capable of absorbing and collecting impurities on the inner wall of the bearing ring.

[0044] A control system. During the grinding process, the control system can adjust the grinding accuracy of the bearing ring by controlling the adjusting component 3, the limiting component 4, the thrust component 5, the positioning component 6, the clamping mechanism 7, the cleaning mechanism 8, and the filtering mechanism 9.

[0045] In this embodiment, during grinding, the bearing ring is placed in the middle of the clamping mechanism 7 and fixed by the clamping mechanism 7. Then, the power component 10 is started, and the power component 10 drives the moving frame 2 to move horizontally along the end face of the workbench 1. All the grinding rollers 14 are in contact with one end side wall of the bearing ring. At the same time, the thrust component 5 at the other end of the bearing ring extends, and the thrust component 5 and all the grinding rollers 14 squeeze the bearing ring from both ends until the abutting force between all the grinding rollers 14 and the bearing ring reaches a preset pressure value range. At this time, the thrust component 5 and all the grinding rollers 14 stop moving, and all the positioning components 6 are in contact with the outer wall of the bearing ring. At this time, the cleaning mechanism 8 is in contact with the inner wall of the bearing ring.

[0046] The second driving component 11 is started and drives the sleeve 16 to rotate. The sleeve 16 drives all the grinding rollers 14 to grind the inner wall of the bearing ring. As the grinding roller 14 grinds, the inner wall thickness of one end of the bearing ring gradually becomes smaller. At this time, the thrust component 5 extends, so that the abutting force between the bearing ring and the grinding roller 14 is within a preset range. As the bearing ring is stressed during grinding at one end, the bearing ring is prone to displacement, resulting in a large deviation in the grinding thickness of each part of the inner wall of the bearing ring. In this solution, at the grinding end, the limiting component 4 and the grinding roller 14 are respectively in contact with and limit the outer wall and the inner wall of one end of the bearing ring, so as to increase the stability of the grinding end of the bearing ring. When the pressure difference between each limiting component 4 and the bearing ring exceeds a preset pressure threshold, at this time, the control system controls all the positioning components 6 to increase the limiting force on the bearing ring, and at the same time, the control system controls the thrust component 5 to extend to increase the limiting force in the horizontal direction of the bearing ring.

[0047] As all the grinding rollers 14 are grinding, all the grinding rollers 14 gradually move toward the inside of the bearing ring, and the contact area between all the grinding rollers 14 and the inner wall of the bearing ring increases, which increases the grinding debris generated by grinding. At the same time, the heat of the bearing ring itself increases, and the grinding debris sticks to the grinding rollers 14 and the inner wall of the bearing ring, which can easily affect the grinding accuracy of the bearing ring. In this solution, external cooling water cools the grinding area of ​​the bearing ring through the sleeve 16. At the same time, as the contact area between all the grinding rollers 14 and the inner wall of the bearing ring increases, the adjustment component 3 can control the increase in the spraying area of ​​the cooling water, the impurity removal mechanism 8 can scrape off the residue on the inner wall of the bearing ring, and the filtering mechanism 9 absorbs and collects impurities and water vapor on the inner wall of the bearing ring.

[0048] like Figure 3 As shown, a deformation-resistant thin-walled bearing grinding processing device provided by the present invention, the adjustment component 3 includes a No. 1 electric telescopic sleeve 31 and a spray hole 32, and a plurality of spray holes 32 are arranged on the end of the sleeve 16 close to the grinding roller 14, and a retractable No. 1 electric telescopic sleeve 31 is fixedly connected to the outside of the sleeve 16, and the No. 1 electric telescopic sleeve 31 can seal the spray holes 32 on the sleeve 16.

[0049] In this embodiment, the No. 1 electric telescopic sleeve 31 moves along the length direction of the sleeve 16 through telescopic motion, thereby controlling the number of conduction holes 32 at one end of the sleeve 16. When the contact area between all grinding rollers 14 and the inner wall of the bearing ring increases, the No. 1 electric telescopic sleeve 31 contracts, thereby increasing the spray area of ​​the external cooling water on the grinding part.

[0050] like Figure 4 As shown, a deformation-resistant thin-walled bearing grinding processing device provided by the present invention, the limit assembly 4 includes an elastic telescopic sleeve 41 and a turntable 42, the grinding roller 14 is externally threadedly connected with the retractable elastic telescopic sleeve 41, and the elastic telescopic sleeve 41 is rotatably connected with the turntable 42.

[0051] In this embodiment, the elastic telescopic sleeve 41 pushes the turntable 42 to elastically abut against the outer wall of the grinding end of the bearing ring. The turntable 42 can clamp and limit the grinding end of the bearing ring together with the grinding roller 14, thereby increasing the stability of the grinding part during grinding of the bearing ring and avoiding one end of the bearing ring from shifting during grinding.

[0052] like Figure 7As shown in the figure, a grinding and processing device for a thin-walled bearing that prevents deformation provided by the present invention. The thrust assembly 5 includes a second electric telescopic sleeve 51 and a fixed sleeve 52. The second electric telescopic sleeve 51 is fixedly connected to the end face of the fixed frame 12. The telescopic end of the second electric telescopic sleeve 51 is fixedly connected to a fixed sleeve 52. The fixed sleeve 52 is set to be frustum-shaped, and the top surface of the fixed sleeve 52 is in communication with the second electric telescopic sleeve 51, and the bottom surface of the fixed sleeve 52 is provided with an opening. A third pressure sensor is provided between the telescopic end and the fixed end of the fixed sleeve 52.

[0053] In this embodiment, the fixed sleeve 52 is frustum-shaped, so that when the fixed sleeve 52 abuts against one end of the bearing ring, it can position the bearing ring horizontally and vertically at the same time, increasing the centering effect of the bearing ring. The fixed sleeve 52 and all the grinding rollers 14 together clamp the bearing ring horizontally. When grinding, when the third pressure sensor senses that the abutting force between the fixed sleeve 52 and the inner wall of the bearing ring decreases to the preset pressure threshold, at this time, the control system controls the fixed sleeve 52 to extend, so that the bearing ring can stably abut against all the grinding rollers 14, ensuring the grinding effect of the bearing ring.

[0054] As Figure 8 As shown in the figure, a grinding and processing device for a thin-walled bearing that prevents deformation provided by the present invention. The positioning assembly 6 includes a first electric rod 61 and a rubber block 62. A plurality of first electric rods 61 are fixedly arranged on the side wall of the fixed sleeve 52. The telescopic ends of the first electric rods 61 are all fixedly connected to rubber blocks 62, and all the rubber blocks 62 are arranged inside the fixed sleeve 52.

[0055] In this embodiment, all the first electric rods 61 drive all the rubber blocks 62 to jointly clamp one end of the bearing ring, ensuring that the axis of the bearing ring coincides with the axis of the sleeve 16, so that the side wall thickness of the bearing ring is uniform when grinding; when the bearing ring is misaligned, at this time, the control system controls all the first electric rods 61 to extend, so that all the first electric rods 61 further clamp the bearing ring, avoiding the misalignment of the bearing ring.

[0056] As Figure 6 As shown in the figure, a grinding and processing device for a thin-walled bearing that prevents deformation provided by the present invention. The clamping mechanism 7 includes a second electric rod 71, a guide seat 72 and a clamping plate 73;

[0057] Both ends of the connecting frame 13 are fixedly connected to second electric rods 71. The telescopic ends of the second electric rods 71 are all fixedly connected to guide seats 72. The arc surface of the guide seat 72 is horizontally slidably connected to a clamping plate 73.

[0058] In this embodiment, two second electric rods 71 are started simultaneously. The two second electric rods 71 extend simultaneously and drive two guide seats 72 to move. The two guide seats 72 drive two clamping plates 73 to clamp the bearing ring at the same time.

[0059] As Figure 5 and Figure 9 shown, a thin-walled bearing grinding and processing device for preventing deformation provided by the present invention. The impurity removal mechanism 8 includes a rotating sleeve 81, a sliding sleeve 82, a third electric telescopic sleeve 83, an arc plate 84, a rubber scraping strip 85, and a first driving component 86;

[0060] The rotating sleeve 81 is rotatably connected to the fixed frame 12. A first driving component 86 for driving the rotating sleeve 81 to rotate is arranged on the fixed frame 12. The rotating sleeve 81 is slidably connected with a sliding sleeve 82 along the length direction. The sliding sleeve 82 is fixedly connected with a third electric telescopic sleeve 83. The telescopic end of the third electric telescopic sleeve 83 is fixedly connected with an arc plate 84. A plurality of rubber scraping strips 85 are arranged on the arc plate 84 along the same rotation direction.

[0061] The third electric telescopic sleeve 83 drives all the arc plates 84 to approach the inner wall of the bearing ring. All the rubber scraping strips 85 are in contact with the inner wall of the bearing ring. The first driving component 86 drives the rotating sleeve 81 to rotate. The rotating sleeve 81 drives the sliding sleeve 82 to rotate. The sliding sleeve 82 drives the rubber scraping strips 85 on all the arc plates 84 to scrape the debris adhered to the inner wall of the bearing ring. All the rubber scraping strips 85 can fit with the inner wall of the bearing ring. On the one hand, it improves the ability to scrape the debris on the inner wall of the bearing ring. On the other hand, the rubber scraping strips 85 can elastically limit the bearing ring and increase the anti-vibration ability when the bearing ring is ground. Further, the rotation direction of the rotating sleeve 81 is opposite to the rotation direction of the sleeve 16, so that the grinding direction of all the grinding rollers 14 on the bearing ring and the rotation direction of all the rubber scraping strips 85 are opposite, so that all the rubber scraping strips 85 can offset part of the friction force in a single rotation direction when the bearing ring is rubbed, and increase the stability of the bearing ring.

[0062] Both the first driving component 86 and the second driving component 11 are composed of a motor and a gear transmission pair.

[0063] As Figure 5 shown, a thin-walled bearing grinding and processing device for preventing deformation provided by the present invention. The filtering mechanism 9 includes a filtering box 91, a conduit 92, and an air pump 93;

[0064] The rubber scraping strip 85 is provided with strip-shaped grooves, and the strip-shaped grooves are in communication with the arc-shaped plate 84 and the third electric telescopic sleeve 83. The rotating sleeve 81 is provided with strip-shaped holes along the length direction, and the strip-shaped holes are in communication with the third electric telescopic sleeve 83 through the end holes on the sliding sleeve 82. The filter box 91 is fixedly connected to the fixing frame 12. One end of the conduit 92 is communicated with the filter box 91, and the other end of the conduit 92 is rotatably connected to one end of the rotating sleeve 81. The conduit 92 is connected with an air pump 93.

[0065] In this embodiment, the air pump 93 pumps air. The debris scraped off by the rubber scraping strip 85 enters the rotating sleeve 81 through the strip-shaped grooves on the rubber scraping strip 85. After that, the debris is filtered in the filter box 91. The suction force of the air pump 93 can collect the debris and prevent the debris from remaining on the rubber scraping strip 85, thus affecting the vibration damping effect of the rubber scraping strip 85 on the bearing ring.

[0066] A thin-walled bearing grinding and processing device for preventing deformation provided by the present invention, the regulation system includes:

[0067] A monitoring module, which includes a first pressure sensor and a second pressure sensor. The end faces of the turntable 42 facing the grinding roller 14 are both provided with first pressure sensors, and the end faces of the rubber blocks 62 facing away from the first electric rod 61 are both provided with second pressure sensors;

[0068] A storage module, which is used to store the pressure differences between all the first pressure sensors at the same time, and the pressure differences between all the second pressure sensors at the same time;

[0069] A processing module, which compares the pressure differences between all the first pressure sensors at the same time and the pressure differences between all the second pressure sensors at the same time with the preset pressure thresholds in the processing module respectively, and forms judgment information; the processing module is preferably a computer processor;

[0070] A control module, which controls the adjustment assembly 3, the limit assembly 4, the thrust assembly 5, the positioning assembly 6, the clamping mechanism 7, the impurity removal mechanism 8 and the filtering mechanism 9 according to the judgment information in the processing module. The control module is preferably a plc controller.

[0071] In this embodiment, when the pressure difference between all the first pressure sensors at the same time exceeds the preset pressure threshold in the processing module, it indicates that the grinding end of the bearing ring is displaced; when the pressure difference between all the second pressure sensors at the same time exceeds the preset pressure threshold in the processing module, it indicates that the other end of the bearing ring away from the grinding end is displaced;

[0072] The detection module can detect both ends of the bearing ring simultaneously, thereby enhancing the monitoring effect on the bearing ring. When the bearing ring has a position offset, the control module then controls all the first electric rods 61 to extend, so that all the first electric rods 61 further clamp the bearing ring. At the same time, it controls the fixed sleeve 52 to extend, enabling the bearing ring to stably abut against all the grinding rollers 14. Further, the regulation system controls all the third electric telescopic sleeves 83 to extend, and drives the rubber scraping strip 85 to further abut against the inner wall of the bearing ring through the third electric telescopic sleeves 83, increasing the overall stability of the bearing ring and preventing the bearing ring from continuously offsetting subsequently. At the same time, the control module controls the power of the air pump 93 to increase, preventing the opening of the strip-shaped groove on the rubber scraping strip 85 from decreasing and causing debris accumulation.
