Description

Technical Field

[0001] This application relates to the technical field of intelligent equipment manufacturing, and particularly relates to a grinding device for processing the outer ring of a bearing. Background Art

[0002] The outer ring of a bearing is one of the components of the bearing. It is located on the outside of the bearing and is used to support the balls and inner ring located inside it. The outer ring moves relative to the inner ring and the balls to form a rotational support function for the rotating mechanical components. When grinding the outer ring of the bearing, it is necessary to cover its entire surface (including the end face, outer groove, and outer ring surface). However, the grinding devices in the prior art have a relatively simple structure and cannot achieve a one-time and efficient grinding operation for the outer ring of the bearing. Specifically, it is manifested in: rigid clamping and fixing of the outer ring of the bearing before grinding, and the need to change positions after grinding (the clamping parts need to be changed for grinding the end face and outer ring surface). This makes the grinding efficiency of the outer ring of the bearing very low, which is obviously not sufficient for the bearing processing that requires one-time and efficient shipment, and seriously reduces the production capacity and increases the manufacturing cost. Application No. CN201920714288.7 discloses a grinding device for processing the outer ring of a bearing with a measurement structure: it only solves the problem of synchronous grinding of the outer groove and the outer ring surface, and it still requires changing the clamping position for grinding the end face of the outer ring of the bearing. Therefore, the efficiency problem during the grinding process of the outer ring of the bearing has not been completely solved. Therefore, through the above objective analysis and comparison and research with the prior art in this application, a grinding device for processing the outer ring of a bearing is proposed. Summary of the Invention

[0003] This application proposes a grinding device for processing the outer ring of a bearing, which has the advantage of high grinding efficiency and is used to solve the problem that all grinding coverage cannot be achieved after one-time clamping and fixing in the prior art.

[0004] To achieve the above object, this application adopts the following technical solution: A grinding device for processing the outer ring of a bearing, comprising: A support base, a fixed table and a first hydraulic cylinder are respectively installed at the bottom and top inside the support base, and a moving mechanism is installed on the front surface of the support base; The telescopic end of the first hydraulic cylinder is fixedly installed with a moving frame. A second motor is installed on the front surface of the moving frame. A roller is rotatably installed inside the moving frame. A buffer sleeve is fixedly sleeved on the outer surface of the roller. Connecting frames are installed on both the front and back surfaces of the moving frame. A first grinding stone is fixedly connected to the side of the connecting frame facing the roller; A pillar is fixedly installed inside the fixed table. A first rotating plate and a second rotating plate are movably sleeved on the outer surface of the pillar. A second grinding stone and a third grinding stone are respectively fixedly installed on the upper surfaces of the first rotating plate and the second rotating plate. A workpiece is placed on the upper surfaces of the second grinding stone and the third grinding stone. A left limiting block is fixedly connected to the bottom of the first rotating plate. A right limiting block is fixedly connected to the bottom of the second rotating plate. A spring is elastically arranged between the left limiting block and the right limiting block.

[0005] Preferably, the moving mechanism includes a second hydraulic cylinder fixedly installed on the front surface of the support base. The telescopic end of the second hydraulic cylinder is fixedly connected to a connecting seat. A third hydraulic cylinder is fixedly installed inside the connecting seat. The telescopic end of the third hydraulic cylinder is fixedly installed with a fixed frame. A first motor is installed inside the fixed frame. A grinding wheel is installed on the output shaft of the first motor.

[0006] Preferably, the buffer sleeve is made of hard rubber, and the outer surface of the buffer sleeve abuts against the outer surface of the workpiece.

[0007] Preferably, a plurality of threaded holes are formed in both the front and back surfaces of the moving frame. Bolts are threadedly installed inside the threaded holes. The connecting frame is press-fitted and installed on the surface of the moving frame through the bolts. The first grinding stone abuts against the end surface of the workpiece.

[0008] Preferably, the connecting frame is made of stainless steel, and the side of the bottom of the connecting frame facing away from the roller is designed to be upturned.

[0009] Preferably, two guide columns are fixedly installed at the top of the inner wall of the support base. The bottom ends of the guide columns are downwardly adapted to penetrate through the bottom of the moving frame.

[0010] Preferably, a placement groove is formed inside the fixed table. The left side of the left limiting block and the right side of the right limiting block respectively abut against the left and right sides of the inner wall of the placement groove.

[0011] Preferably, clamping grooves are formed on the opposite surfaces of the left limiting block and the right limiting block. The two ends of the spring are elastically connected to the inner walls of the two clamping grooves respectively.

[0012] Preferably, when the included angle between the first rotating plate and the second rotating plate increases through rotation, the opposite surfaces of the left limiting block and the right limiting block are adapted to abut against each other.

[0013] The beneficial effects of the present invention are as follows: 1. This device has been redesigned to achieve the function of clamping a workpiece once and comprehensively synchronously grinding it, effectively improving the grinding efficiency of the device. The workpiece is supported by a first rotating plate and a second rotating plate that rotate at an angle to each other. The second grinding stone and the third grinding stone on them are in contact with the outer surface of the workpiece. Then, in cooperation with the moving frame, rollers, and buffer sleeves driven by a first hydraulic cylinder, the workpiece is clamped synchronously in three directions. At the same time, by setting two groups of connecting frames and a first grinding stone on the front and back sides of the moving frame, the first grinding stone is in contact with the end face of the workpiece. Then, through the two-axis movement of the moving mechanism, the outer surface of the grinding wheel is in contact with the outer groove of the workpiece. Then, a second motor drives the rollers and the buffer sleeves to rotate, and the friction between the buffer sleeve and the outer surface of the workpiece drives the workpiece to rotate self-rotationally. Finally, the synchronous grinding of the outer ring surface, outer groove, and end face of the workpiece is achieved. This design can significantly improve the grinding efficiency of the device.

[0014] 2. The end face grinding function of this device has been expanded, that is, the device can adapt to workpieces of different shapes and sizes by changing the position of the connecting frame on the surface of the moving frame. By opening multiple groups of threaded holes on the front and back sides of the moving frame and using bolts to fix the connecting frame, the connecting frame can make a circular motion around the arc surface at the bottom of the moving frame. According to workpieces of different sizes, change the position fixed by the bolts. As long as the connecting frame drives the first grinding stone to cover the end face of the workpiece, the end face of the workpiece can be ground comprehensively during self-rotation. This design not only simplifies the fixed clamping process of the workpiece but also improves the applicability of the device.

[0015] 3. On the inner wall of the placement groove, a left limit block and a right limit block are respectively in contact with the two sides of the inner wall of the placement groove, one on the left and one on the right. The first rotating plate is fixedly connected to the left limit block, and the second rotating plate is fixedly connected to the right limit block. The purpose of this design is to maintain the left-right symmetry of the first rotating plate and the second rotating plate in a stationary state. Since this device needs to adapt and support workpieces of different sizes, the rotation and rest of the first rotating plate and the second rotating plate need to be symmetrically set so as to keep the centers of workpieces of different sizes on a vertical line. When the workpiece is on the upper surfaces of the second grinding stone and the third grinding stone and presses down on the first rotating plate and the second rotating plate, the first rotating plate and the second rotating plate start to drive the left limit block and the right limit block to make a circular motion towards each other. Finally, the included angle between the first rotating plate and the second rotating plate is maintained at a fixed value by the contact of the left limit block and the right limit block. At this time, the first rotating plate and the second rotating plate can provide rigid support for the workpiece. When the left limit block and the right limit block move, the spring generates a resilience force through compression and forms a clamping force on the workpiece to provide buffering for the downward movement of the workpiece.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts belong to the scope of protection of the present application.

[0020] Please refer to Figures 1-9 , this embodiment discloses a grinding device for processing the outer ring of a bearing, including: Support base 1, a fixed platform 14 and a first hydraulic cylinder 2 are respectively installed at the bottom and top inside the support base 1, and a moving mechanism 4 is installed on the front of the support base 1; The telescopic end of the first hydraulic cylinder 2 is fixedly installed with a moving frame 5. A second motor 8 is installed on the front of the moving frame 5. A roller 6 is rotatably installed inside the moving frame 5. A buffer sleeve 7 is fixedly sleeved on the outer surface of the roller 6. Connecting frames 11 are installed on both the front and back of the moving frame 5. A first grinding stone 12 is fixedly connected to one side of the connecting frame 11 facing the roller 6; A support column 15 is fixedly installed inside the fixed platform 14. A first rotating plate 17 and a second rotating plate 19 are movably sleeved on the outer surface of the support column 15. A second grinding stone 18 and a third grinding stone 20 are respectively fixedly installed on the upper surfaces of the first rotating plate 17 and the second rotating plate 19. A workpiece 13 is placed on the upper surfaces of the second grinding stone 18 and the third grinding stone 20. A left limiting block 21 is fixedly connected to the bottom of the first rotating plate 17. A right limiting block 22 is fixedly connected to the bottom of the second rotating plate 19. A spring 24 is elastically arranged between the left limiting block 21 and the right limiting block 22; This device has been redesigned to achieve the function of clamping a workpiece 13 once and comprehensively and synchronously grinding it, effectively improving the grinding efficiency of the device. The workpiece 13 is supported by the first rotating plate 17 and the second rotating plate 19 that rotate at an angle to each other. The second grinding stone 18 and the third grinding stone 20 on them are in contact with the outer surface of the workpiece 13. Then, in cooperation with the moving frame 5, the roller 6 and the buffer sleeve 7 driven by the first hydraulic cylinder 2, the workpiece 13 is clamped synchronously in three directions. At the same time, by setting two groups of connecting frames 11 and the first grinding stone 12 on the front and back sides of the moving frame 5, the first grinding stone 12 is in contact with the end face of the workpiece 13. Then, through the two-axis movement of the moving mechanism 4, the outer surface of the grinding wheel 46 is in contact with the outer groove of the workpiece 13. Then, the second motor 8 drives the roller 6 and the buffer sleeve 7 to rotate, and the friction between the buffer sleeve 7 and the outer surface of the workpiece 13 drives the workpiece 13 to rotate automatically. Finally, the synchronous grinding of the outer ring surface, the outer groove and the end face of the workpiece 13 is realized. This design can significantly improve the grinding efficiency of the device.

[0021] In this embodiment, the moving mechanism 4 includes a second hydraulic cylinder 41 fixedly installed on the front of the support base 1. The telescopic end of the second hydraulic cylinder 41 is fixedly connected to a connecting seat 42. A third hydraulic cylinder 43 is fixedly installed inside the connecting seat 42. The telescopic end of the third hydraulic cylinder 43 is fixedly installed with a fixed frame 44. A first motor 45 is installed inside the fixed frame 44. A grinding wheel 46 is installed on the output shaft of the first motor 45; The entire moving mechanism 4 serves to move the spatial position of the grinding wheel 46. After the workpiece 13 is pressed and fixed downward by the buffer sleeve 7, the second hydraulic cylinder 41 drives the connecting seat 42 to move up and down. After the third hydraulic cylinder 43 drives the grinding wheel 46 into the inner ring area of the workpiece 13, the second hydraulic cylinder 41 continues to adjust the height of the grinding wheel 46 so that the outer surface of the grinding wheel 46 abuts against the outer groove of the workpiece 13. When the second motor 8, the roller 6, and the buffer sleeve 7 drive the workpiece 13 to rotate, the grinding wheel 46 can either remain fixed and slide against the outer groove area of the workpiece 13 to provide a grinding function, or reverse under the drive of the first motor 45 to improve the grinding efficiency of the outer groove of the workpiece 13.

[0022] In this embodiment, the buffer sleeve 7 is made of hard rubber, and the outer surface of the buffer sleeve 7 abuts against the outer surface of the workpiece 13; The buffer sleeve 7 is responsible for contacting the workpiece 13 and preventing the workpiece 13 from directly contacting rigid components and being damaged. Moreover, the flexible characteristics of the buffer sleeve 7 enable it to generate frictional force after deforming when abutting against the workpiece 13 and drive the workpiece 13 to rotate. The second grinding stone 18 and the third grinding stone 20 are not fixed either under the support of the first rotating plate 17 and the second rotating plate 19. When the first hydraulic cylinder 2 drives the downward moving frame 5, the roller 6, and the buffer sleeve 7 downward, they will rotate downward and increase the angle between the first rotating plate 17 and the second rotating plate 19 to provide buffering for the workpiece 13.

[0023] In this embodiment, a plurality of sets of threaded holes 9 are opened on the front and back surfaces of the moving frame 5. Bolts 10 are installed with internal threads in the threaded holes 9, and the connecting frame 11 is press-fitted and installed on the surface of the moving frame 5 through the bolts 10. The first grinding stone 12 abuts against the end face of the workpiece 13; The device expands the end face grinding function of the workpiece 13, that is, the device can adapt to workpieces 13 with different outer shapes and sizes by changing the position of the connecting frame 11 on the surface of the moving frame 5. By opening a plurality of sets of threaded holes 9 on the front and back sides of the moving frame 5 and using bolts 10 to fix the connecting frame 11, the connecting frame 11 can make a circular motion around the arc surface at the bottom of the moving frame 5. According to workpieces 13 of different sizes, change the position where the bolts 10 are fixed. As long as the connecting frame 11 drives the first grinding stone 12 to cover the end face of the workpiece 13, the end face of the workpiece 13 can be comprehensively ground during its rotation. This design not only simplifies the fixed clamping process of the workpiece 13 but also improves the applicability of the device.

[0024] In this embodiment, the connecting frame 11 is made of stainless steel, and the side of the bottom of the connecting frame 11 facing away from the roller 6 is designed to be upturned; The connecting frame 11 is made of stainless steel and can be bent and deformed to a certain extent and restored. With this design, when the connecting frame 11 drives the first grinding stone 12 to cover the end face of the workpiece 13, the workpiece 13 pushes the first grinding stone 12 and the connecting frame 11 outward through limiting. At this time, the reaction force generated by the deformation of the connecting frame 11 can not only make the first grinding stone 12 fit more closely with the end face of the workpiece 13, but also prevent the workpiece 13 from tipping over through the front-back symmetric design, further improving the stability of the workpiece 13.

[0025] In this embodiment, two groups of guide posts 3 are fixedly installed at the top of the inner wall of the support base 1, and the bottom ends of the guide posts 3 are adaptively penetrated downward through the bottom of the moving frame 5; The guide posts 3 can penetrate through both sides of the moving frame 5. When the hydraulic cylinder 1 drives the moving frame 5 to move up and down, the guide posts 3 mainly provide a guiding function for the moving frame 5.

[0026] In this embodiment, a placement groove 16 is opened inside the fixed table 14, and the left side of the left limit block 21 and the right side of the right limit block 22 are respectively abutted against the left and right sides of the inner wall of the placement groove 16; On the inner wall of the placement groove 16, the left limit block 21 and the right limit block 22 are respectively abutted against the two sides of the inner wall of the placement groove 16, one on the left and the other on the right. The first rotating plate 17 is fixedly connected to the left limit block 21, and the second rotating plate 19 is fixedly connected to the right limit block 22. The purpose of this design is to maintain the left-right symmetry of the first rotating plate 17 and the second rotating plate 19 in the static state. Since this device needs to adaptively support workpieces 13 of different sizes, the rotation and stillness of the first rotating plate 17 and the second rotating plate 19 need to be symmetrically arranged so as to keep the centers of workpieces 13 of different sizes on a vertical line. When the workpiece 13 is located on the upper surfaces of the second grinding stone 18 and the third grinding stone 20 and presses down on the first rotating plate 17 and the second rotating plate 19, the first rotating plate 17 and the second rotating plate 19 start to drive the left limit block 21 and the right limit block 22 to perform circumferential movement towards each other. Finally, the included angle between the first rotating plate 17 and the second rotating plate 19 is maintained at a fixed value through the abutment of the left limit block 21 and the right limit block 22. At this time, the first rotating plate 17 and the second rotating plate 19 can provide rigid support for the workpiece 13. When the left limit block 21 and the right limit block 22 move, the spring 24 generates a restoring force through compression and forms a clamping force on the workpiece 13, providing buffering for the workpiece 13 when it moves downward.

[0027] In this embodiment, clamping grooves 23 are opened on the opposite surfaces of the left limit block 21 and the right limit block 22, and the two ends of the spring 24 are elastically connected to the inner walls of the two groups of clamping grooves 23 respectively; The clamping grooves 23 elastically support the left limit block 21 and the right limit block 22, so as to buffer the workpiece 13 when the first rotating plate 17 and the second rotating plate 19 support the workpiece 13.

[0028] In this embodiment, when the included angle between the first rotating plate 17 and the second rotating plate 19 increases due to rotation, the opposite surfaces of the left limiting block 21 and the right limiting block 22 are adapted and abutted against each other; When the left limiting block 21 and the right limiting block 22 are abutted, the included angle between the first rotating plate 17 and the second rotating plate 19 reaches the maximum and stops rotating, thereby providing a rigid support for the workpiece 13.

[0029] Working principle: When the device is working, first, the first hydraulic cylinder 2 is started, and it drives the moving frame 5 and the roller 6 to move upward to the highest point. The workpiece 13 is placed on the upper surfaces of the second grinding stone 18 and the third grinding stone 20, and the workpiece 13 is kept stable by relying on the frictional force of the second grinding stone 18 and the third grinding stone 20 on the outer surface of the workpiece 13; Then, the first hydraulic cylinder 2 is started, and it drives the moving frame 5, the roller 6 and the buffer sleeve 7 downward, so that the outer surface of the buffer sleeve 7 abuts against the outer surface of the workpiece 13. At this time, the moving frame 5, the roller 6 and the buffer sleeve 7 continue to move downward, thereby pressing the first rotating plate 17 and the second rotating plate 19 to rotate around the axis of the support column 15 downward. The included angle between the first rotating plate 17 and the second rotating plate 19 increases. As Figure 5 、 Figure 6 shown, when the first rotating plate 17 and the second rotating plate 19 rotate outward respectively, they will respectively drive the left limiting block 21 and the right limiting block 22 to make circumferential motions towards each other at the same time, compress the spring 24. When the opposite surfaces of the left limiting block 21 and the right limiting block 22 are abutted, the first rotating plate 17 and the second rotating plate 19 stop rotating and provide a rigid support for the workpiece 13; Before the buffer sleeve 7 contacts the outer surface of the workpiece 13 for a period of time, the two groups of connecting frames 11 and the first grinding stone 12 located on the front and rear sides of the moving frame 5 also move downward accordingly. First, the upturned part at the bottom end of the workpiece 13 abuts against the end of the workpiece 13, and forms pressures with the same magnitude and opposite directions on the front and rear ends of the workpiece 13 to maintain the stability of the workpiece 13. Then, the connecting frame 11 bends towards the side away from the workpiece 13 under the limiting action of the end of the workpiece 13, and the first grinding stone 12 is also pushed outward by the workpiece 13 through its chamfer design, so that the first grinding stone 12 abuts against the end of the workpiece 13; Then, the second hydraulic cylinder 41 is started and drives the connecting seat 42 to move, so that the axes of the first motor 45 and the grinding wheel 46 are at the same height as the center of the workpiece 13. Then, the third hydraulic cylinder 43 is started, and it pushes the fixed frame 44, the first motor 45 and the grinding wheel 46 forward, so that the grinding wheel 46 enters the inner ring area of the workpiece 13. Then, the second hydraulic cylinder 41 is started to continue driving the connecting seat 42, the fixed frame 44 and the grinding wheel 46 downward, so that the outer surface of the grinding wheel 46 abuts against the outer groove of the workpiece 13; Finally, enter the grinding stage. Start motor two 8, which drives the roller 6 and the buffer sleeve 7 to rotate. The buffer sleeve 7 drives the workpiece 13 to rotate through the frictional force generated by abutting against the workpiece 13, causing a rolling abutment between the buffer sleeve 7 and the workpiece 13. At this time, while the workpiece 13 is rotating on its own axis, its outer ring surface is ground by sliding abutting against the second grinding stone 18 and the third grinding stone 20. At the same time, the front and rear groups of the first grinding stones 12 just abut against the end face of the workpiece 13 and slide relative to each other for end face grinding. Start motor one 45 and drive the grinding wheel 46 to rotate. The rotation direction of the grinding wheel 46 is opposite to the rotation direction of the workpiece 13, thereby completing the grinding of the outer groove area of the workpiece 13.
