Description

Technical Field

[0001] The present invention belongs to the technical field of inner bearing grinding and polishing, and particularly relates to a bearing inner ring processing device. Background Art

[0002] The inner ring of a bearing is a key component of a rolling bearing. It is located inside the bearing and is usually used in cooperation with a journal. For example, in a bearing installed on a motor shaft, the inner ring is tightly sleeved on the outer periphery of the motor shaft. Its main function is to provide a stable annular raceway for the rolling elements and rotate together with the shaft.

[0003] In the prior art, after the production of the bearing inner ring, it is necessary to grind and polish the inner wall of the bearing inner ring so that the accuracy is higher when the bearing inner ring is in cooperation with the journal.

[0004] When the bearing inner ring is ground and polished, the inner ring of the bearing is clamped and fixed by a fixture at the position of the machining lathe. Then, the grinding structure penetrates into the inner side of the bearing inner ring, and the inner wall of the bearing inner ring is ground and polished by the grinding structure. After the polishing is completed, the bearing inner ring is removed from the fixture position. The whole process is inefficient. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a bearing inner ring grinding device with high grinding efficiency.

[0006] The technical solution adopted to solve the above technical problem is: a bearing inner ring processing device, including a chain conveyor belt arranged inside a processing support frame. A plurality of evenly distributed inner ring fixators for fixing the bearing inner ring are fixedly connected to the surface of the chain conveyor belt. A processing integrated structure for polishing the bearing inner ring is fixedly connected to the middle of any one side of the processing support frame.

[0007] Through the above technical solution, the chain conveyor belt can drive the inner ring fixator to move. The inner ring of the bearing is clamped and fixed by the inner ring fixator. When the chain conveyor belt drives the corresponding inner ring fixator to move to the position of the processing integrated structure, the inner ring of the bearing at the position of the inner ring fixator is ground and processed by the processing integrated structure. The degree of mechanization is high and the grinding efficiency is high.

[0008] The plurality of inner ring fixators include a fixed mounting seat fixedly connected through the chain conveyor belt. A protective housing is fixedly connected to the upper surface of the fixed mounting seat. A limiting and adjusting structure is arranged on the inner wall of the protective housing. Two symmetrically arranged inner ring claws for clamping and fixing the bearing inner ring penetrate through the upper surface of the protective housing.

[0009] Through the above technical solution, the fixed mounting seat is made of stainless steel material, which is fixedly connected to the chain plate of the chain plate conveyor belt, so as to stably fix the inner ring holder on the surface of the chain plate conveyor belt, making it more stable during operation and grinding. The protective shell can protect the internal structure, preventing metal powder from falling onto the internal structure during grinding and affecting the normal use of the internal structure. Moreover, the protective shell has the function of fixedly supporting the internal structure. The limit adjustment structure can fix and position when the inner ring jaws are pressed together, so that the bearing inner ring is fully fixed by the inner ring jaws.

[0010] Furthermore, a guiding arc-shaped block is fixedly connected to the center position of the upper surface of the fixed mounting seat. The upper surface of the guiding arc-shaped block is provided with an arc-shaped groove, and an installation groove is opened at the bottom position of the arc-shaped groove of the guiding arc-shaped block. A jacking spring is fixedly connected to the bottom position of the installation groove.

[0011] Through the above technical solution, the arc-shaped groove arranged at the position of the guiding arc-shaped block is arranged in a "U" shape, which can be slidably matched with the rotation connecting claws arranged in an arc shape, enabling the horizontal positioning blocks to cooperate with each other. Moreover, the installation groove arranged at the position of the guiding arc-shaped block can install the jacking spring. When the jacking spring is pressed down by the rotation connecting claws, the jacking spring is compressed and stores energy. When the limit adjustment structure no longer fixes and limits the rotation connecting claws, the jacking spring quickly jacks up, causing the inner ring jaws to reset.

[0012] Furthermore, rotation connecting claws arranged in an arc shape are fixedly connected to the lower surface positions of both inner ring jaws. The outer side positions of the rotation connecting claws are slidably connected to the arc-shaped grooves of the guiding arc-shaped block, and the bottoms of both rotation connecting claws are in contact with the top of the jacking spring. A limit fixing shaft is rotatably connected through both rotation connecting claws. Clamping and fixing structures are arranged at both ends of the limit fixing shaft near the limit adjustment structure, and both ends of the limit fixing shaft are slidably connected through the side wall of the protective shell.

[0013] Through the above technical solution, when the rotation connecting claws rotate around the limit fixing shaft, the inner ring jaws can be closed or unfolded to clamp and fix or release the bearing inner ring. The limit fixing shaft can install the limit rotation connecting claws, and the rotation connecting claws can rotate around the limit fixing shaft to adjust the closing and unfolding of the inner ring jaws. Moreover, the limit fixing shaft can enable the rotation connecting claws to move in the vertical direction, making the rotation connecting claws cooperate with the arc grooves of the guiding arc-shaped block. The clamping and fixing structures can cooperate with the limit adjustment structure to assist in fixing the limit fixing shaft.

[0014] Furthermore, the clamping and fixing structure includes a spring groove opened on the surface of the limit fixing shaft. A clamping slider is slidably connected to the inner wall of the spring groove. A slope is arranged on the lower surface position of the clamping slider, and a clamping spring is fixedly connected between the clamping slider and the inner wall of the spring groove.

[0015] Through the above technical solution, the spring groove can be used to install the clamping slider and the clamping spring. A slope is provided on the lower surface of the clamping slider, which can cooperate with the slope on the upper surface of the positioning pin, so that the clamping slider cooperates with the positioning pin, the clamping slider is pressed into the spring groove, the limit fixing shaft is pressed down, and the clamping spring makes the clamping slider reset and eject. The clamping slider is blocked by the positioning pin to prevent the limit fixing shaft from rebounding.

[0016] Furthermore, the limit adjustment structure includes a limit groove block fixedly connected to the inner wall of the protective housing. A limit slider is slidably connected to the position of the limit groove block. A positioning fixed block is fixedly connected to the position of the limit slider. A plurality of uniformly distributed pin slots are opened from top to bottom at both ends of the positioning fixed block. A positioning pin is slidably connected to the inner walls of the plurality of pin slots. A positioning spring is fixedly connected between the positioning pin and the inner wall of the pin slot. A slope is provided on the upper surface of the positioning pin.

[0017] Through the above technical solution, the limit groove block can support and limit the limit slider, facilitating the lateral adjustment of the limit adjustment structure. When the positioning pin no longer cooperates with the clamping slider when the limit slider and the positioning fixed block move laterally, the control toggle rod rebounds under the action of the jacking spring.

[0018] Furthermore, a control toggle rod is fixedly connected to the middle position of any one side of the positioning fixed block. The control toggle rod is slidably connected through the protective housing. A slope is provided at the outer end of the control toggle rod located outside the protective housing. A reset spring is fixedly connected between the side of the positioning fixed block close to the control toggle rod and the inner wall of the protective housing, and the reset spring is concentric with the control toggle rod.

[0019] Through the above technical solution, when the inner ring retainer moves as a whole, when the control toggle rod moves to the position of the toggle block, the toggle block will squeeze the control toggle rod, so that the control toggle rod will squeeze the positioning fixed block, causing the positioning fixed block to shift laterally, separating the positioning pin from the clamping slider, realizing the separation of the inner ring jaws. During this process, the reset spring is stretched. When the control toggle rod and the toggle block are no longer in contact, the positioning fixed block laterally moves back to its original position under the action of the reset spring.

[0020] Furthermore, elastic cushion seats are fixedly connected to the inner walls of the two inner ring jaws. The elastic cushion seats are made of copper material. Horizontal positioning blocks are fixedly connected to both sides of the two inner ring jaws.

[0021] Through the above technical solution, the elastic pad seat made of copper material is relatively soft and will not cause indentations on the outer surface of the inner ring of the bearing when clamping the inner ring of the bearing with the inner ring jaws, effectively protecting the inner ring of the bearing. The horizontal positioning block can perform lateral positioning on the inner ring of the bearing to prevent the inner ring of the bearing from disengaging from the inner ring jaws during grinding and polishing.

[0022] Furthermore, a main drive motor is fixedly connected to the side wall position of the processing support frame through a fixing frame. The drive end of the main drive motor faces the side of the chain conveyor belt and is connected to the rotating shaft of the chain conveyor belt through a speed reducer. One end of the upper surface of the processing support frame and near the control toggle rod is fixedly connected with a toggle block.

[0023] Through the above technical solution, the main drive motor provides power for the operation of the chain conveyor belt, and the speed reducer can make the chain conveyor belt maintain a suitable speed and increase the output torque of the main drive motor. The control toggle rod can be adjusted through the toggle block, so that the inner ring jaws open. When the chain conveyor belt moves to the end of the processing support frame, under the action of gravity, the polished inner ring of the bearing is collected in the article collection structure.

[0024] Furthermore, the processing integrated structure includes a polishing platform fixedly connected to the middle position of the side wall of the processing support frame. The upper surface of the polishing platform is fixedly connected with a horizontal adjuster for adjusting in the X-axis direction and the Y-axis direction. The surface of the horizontal adjuster is fixedly connected with a height adjuster, and the telescopic end of the height adjuster is fixedly connected with a polishing machine main body.

[0025] Through the above technical solution, the polishing platform can support the entire processing integrated structure. The horizontal adjuster enables the polishing machine main body to move together with the inner ring fixator. At the same time, the horizontal adjuster facilitates the polishing head of the polishing machine main body to extend into the inner side of the inner ring of the bearing, and through the horizontal adjuster, the polishing machine main body and the inner ring of the bearing move synchronously for convenient grinding. The horizontal adjuster consists of two vertically crossed electric linear guide rails, which can realize the adjustment of the height adjuster and the polishing machine main body in the X-axis direction and the Y-axis direction.

[0026] The beneficial effects of the present invention are as follows: By setting the inner ring fixator in the present invention, the inner ring of the bearing to be polished is placed between the inner ring jaws at the corresponding position, and the inner ring of the bearing is pressed downward so that the inner ring of the bearing is clamped and fixed. Then, the inner ring of the bearing is ground and polished by the polishing machine main body. After the polishing is completed, the two inner ring jaws can be opened through the toggle block. When the inner ring of the bearing rotates below the chain conveyor belt, the inner ring of the bearing drops under the action of gravity to complete automatic material taking. The entire grinding process is highly efficient and highly mechanized. The manual operation part is far away from the polishing machine main body, and the use and operation are safer.

Detailed implementation manners

[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the 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.

[0036] As Figure 1-7As shown in the figure, a bearing inner ring processing device according to this embodiment includes a chain plate conveyor belt 3 arranged in a processing support frame 1. A number of evenly distributed inner ring fixators 2 for fixing the bearing inner ring are fixedly connected to the surface of the chain plate conveyor belt 3. A processing integrated structure 4 for polishing the bearing inner ring is fixedly connected to the middle of any one side of the processing support frame 1. The chain plate conveyor belt 3 can drive the inner ring fixator 2 to move. By clamping and fixing the inner ring of the bearing with the inner ring fixator 2, when the chain plate conveyor belt 3 drives the corresponding inner ring fixator 2 to move to the position of the processing integrated structure 4, the processing integrated structure 4 grinds and processes the bearing inner ring at the position of the inner ring fixator 2. It has a high degree of mechanization and high grinding efficiency.

[0037] The processing integrated structure 4 includes a polishing platform 40 fixedly connected to the middle position of the side wall of the processing support frame 1. A horizontal adjuster 43 for adjusting in the X-axis direction and the Y-axis direction is fixedly connected to the upper surface of the polishing platform 40. A height adjuster 42 is fixedly connected to the surface of the horizontal adjuster 43. The telescopic end of the height adjuster 42 is fixedly connected to a polishing machine main body 41. The polishing platform 40 can support the entire processing integrated structure 4. The horizontal adjuster 43 enables the polishing machine main body 41 to move together with the inner ring fixator 2. At the same time, the horizontal adjuster 43 facilitates the polishing head of the polishing machine main body 41 to extend into the inner side of the bearing inner ring, and through the horizontal adjuster 43, the polishing machine main body 41 moves synchronously with the bearing inner ring to facilitate grinding. The horizontal adjuster 43 is composed of two vertically crossed electric linear guides, which can realize the adjustment of the height adjuster 42 and the polishing machine main body 41 in the X-axis direction and the Y-axis direction.

[0038] A main drive motor 5 is fixedly connected to the side wall position of the processing support frame 1 through a fixing frame. The drive end of the main drive motor 5 faces the side of the chain plate conveyor belt 3 and is connected to the rotating shaft of the chain plate conveyor belt 3 through a speed reducer. A toggle block 6 is fixedly connected to one end of the upper surface of the processing support frame 1 and close to the control toggle lever 26. The main drive motor 5 provides power for the operation of the chain plate conveyor belt 3, and through the speed reducer, the chain plate conveyor belt 3 can maintain a suitable rotational speed and increase the output torque of the main drive motor 5. By adjusting the control toggle lever 26 through the toggle block 6, the inner ring claw 202 is unfolded. Then, when the chain plate conveyor belt 3 moves to the end of the processing support frame 1, under the action of gravity, the polished bearing inner ring is collected in the article collection structure.

[0039] A number of inner ring fixers 2 include a fixed mounting base 20 fixedly connected to the chain plate conveyor belt 3 in a penetrating manner. A protective housing 201 is fixedly connected to the upper surface of the fixed mounting base 20. A limiting and adjusting structure is provided on the inner wall of the protective housing 201. Two symmetrically arranged inner ring claws 202 for clamping and fixing the inner ring of the bearing are provided through the upper surface of the protective housing 201. The fixed mounting base 20 is made of stainless steel material and is fixedly connected to the chain plate of the chain plate conveyor belt 3, so as to stably fix the inner ring fixer 2 on the surface of the chain plate conveyor belt 3, making it more stable during operation and grinding. The protective housing 201 can protect the internal structure, preventing metal powder from falling onto the internal structure during grinding and affecting the normal use of the internal structure. Moreover, the protective housing 201 has the function of fixedly supporting the internal structure. The limiting and adjusting structure can perform fixed positioning when the inner ring claws 202 are pressed down and closed, so that the inner ring of the bearing is fully fixed by the inner ring claws 202.

[0040] Elastic cushion seats 210 are fixedly connected to the inner walls of the two inner ring claws 202. The elastic cushion seats 210 are made of copper material. Horizontal positioning blocks 200 are fixedly connected to both sides of the two inner ring claws 202. The copper elastic cushion seats 210 are relatively soft and will not cause indentations on the outer surface of the inner ring of the bearing when clamping the inner ring of the bearing with the inner ring claws 202, effectively protecting the inner ring of the bearing. The horizontal positioning blocks 200 can perform lateral positioning on the inner ring of the bearing to prevent the inner ring of the bearing from detaching from the inner ring claws 202 during grinding and polishing.

[0041] The limiting and adjusting structure includes a limiting groove block 28 fixedly connected to the inner wall of the protective housing 201. A limiting slider 203 is slidably connected to the position of the limiting groove block 28. A positioning and fixing block 27 is fixedly connected to the position of the limiting slider 203. A number of uniformly distributed pin slots 204 are opened from top to bottom at both ends of the positioning and fixing block 27. A positioning pin 206 is slidably connected to the inner walls of the number of pin slots 204. A positioning spring 205 is fixedly connected between the positioning pin 206 and the inner wall of the pin slot 204. A slope is provided on the upper surface of the positioning pin 206. The limiting groove block 28 can support and limit the limiting slider 203, facilitating lateral adjustment of the limiting and adjusting structure. When the limiting slider 203 and the positioning and fixing block 27 move laterally and the positioning pin 206 no longer cooperates with the clamping slider 209, the control toggle lever 26 rebounds under the action of the jacking spring 22.

[0042] A control toggle lever 26 is fixedly connected to the middle position on either side of the positioning and fixing block 27. The control toggle lever 26 is slidably connected through the protective housing 201. A slope is provided at the outer end of the control toggle lever 26 located outside the protective housing 201. A return spring 25 is fixedly connected between the side of the positioning and fixing block 27 close to the control toggle lever 26 and the inner wall of the protective housing 201, and the return spring 25 is concentric with the control toggle lever 26. When the inner ring retainer 2 moves as a whole, when the control toggle lever 26 moves to the position of the toggle block 6, the toggle block 6 will squeeze the control toggle lever 26, causing the control toggle lever 26 to squeeze the positioning and fixing block 27, causing the positioning and fixing block 27 to shift laterally, separating the positioning pin 206 from the clamping slider 209, realizing the separation of the inner ring jaws 202. During this process, the return spring 25 is stretched. When the control toggle lever 26 and the toggle block 6 are no longer in contact, the positioning and fixing block 27 moves horizontally and resets under the action of the return spring 25.

[0043] A guiding arc-shaped block 21 is fixedly connected to the central position on the upper surface of the fixed mounting base 20. The upper surface of the guiding arc-shaped block 21 is provided with an arc-shaped groove, and an installation groove 23 is opened at the bottom position of the arc-shaped groove of the guiding arc-shaped block 21. A jacking spring 22 is fixedly connected to the bottom position of the installation groove 23. The arc-shaped groove provided at the position of the guiding arc-shaped block 21 is arranged in a "U" shape and can be slidably matched with the arc-shaped rotating connection claw 29, enabling the horizontal positioning blocks 200 to cooperate with each other. And the installation groove 23 provided at the position of the guiding arc-shaped block 21 can install the jacking spring 22. When the jacking spring 22 is pressed down by the rotating connection claw 29, the jacking spring 22 is compressed and stores energy. When the limiting and adjusting structure no longer fixes and limits the rotating connection claw 29, the jacking spring 22 quickly jacks up, causing the inner ring jaws 202 to reset.

[0044] Arc-shaped rotating connection claws 29 are fixedly connected to the lower surface positions of the two inner ring jaws 202. The outer side positions of the rotating connection claws 29 are slidably connected to the arc-shaped grooves of the guiding arc-shaped block 21, and the bottoms of the two rotating connection claws 29 are in contact with the tops of the jacking springs 22. A limiting and fixing shaft 24 is rotatably connected through the positions of the two rotating connection claws 29. Clamping and fixing structures are provided at both ends of the limiting and fixing shaft 24 close to the limiting and adjusting structure. Both ends of the limiting and fixing shaft 24 are slidably connected through the side walls of the protective housing 201. When the rotating connection claws 29 rotate at the position of the limiting and fixing shaft 24, the inner ring jaws 202 can be closed or unfolded to clamp and fix or release the inner ring of the bearing. The limiting and fixing shaft 24 can install the limiting and rotating connection claws 29, and the rotating connection claws 29 can rotate around the limiting and fixing shaft 24 to adjust the closing and unfolding of the inner ring jaws 202. And the limiting and fixing shaft 24 can enable the rotating connection claws 29 to move in the vertical direction, enabling the rotating connection claws 29 to cooperate with the arc grooves of the guiding arc-shaped block 21. The clamping and fixing structure can cooperate with the limiting and adjusting structure to assist in fixing the limiting and fixing shaft 24.

[0045] The clamping and fixing structure includes a spring groove 207 formed on the surface of the limit fixing shaft 24. A clamping slider 209 is slidably connected to the inner wall of the spring groove 207. A slope is provided on the lower surface of the clamping slider 209. A clamping spring 208 is fixedly connected between the clamping slider 209 and the inner wall of the spring groove 207. The spring groove 207 can install the clamping slider 209 and the clamping spring 208. The slope provided on the lower surface of the clamping slider 209 can cooperate with the slope on the upper surface of the positioning pin 206, so that the clamping slider 209 cooperates with the positioning pin 206, causing the clamping slider 209 to be pressed into the spring groove 207, pressing down the limit fixing shaft 24, and the clamping spring 208 causes the clamping slider 209 to reset and eject. The positioning pin 206 blocks the clamping slider 209 to prevent the limit fixing shaft 24 from rebounding.

[0046] The working principle of this embodiment is as follows. When it is necessary to polish the corresponding inner ring of the bearing, place the inner ring of the bearing between the two inner ring jaws 202 and press down the inner ring of the bearing, so that the inner ring jaws 202 and the rotating connection jaws 29 move downward. Under the action of the guiding arc block 21, the two rotating connection jaws 29 are brought closer together, and then the two inner ring jaws 202 are brought closer together to fix and clamp the inner ring of the bearing. Adjust the height regulator 42 so that the center of the grinding head of the polishing machine main body 41 is on the same horizontal plane as the center of the clamped inner ring of the bearing. Start the main drive motor 5 and the horizontal regulator 43;

[0047] Drive the chain conveyor belt 3 by the main drive motor 5. When the inner ring of the bearing moves to the position of the polishing machine main body 41, the horizontal regulator 43 drives the polishing machine main body 41 to move and penetrate into the inside of the inner ring of the bearing, and polish it with the grinding head of the polishing machine main body 41. And the horizontal regulator 43 drives the height regulator 42 and the polishing machine main body 41 to move together with the chain conveyor belt 3 to fully polish the inner ring of the bearing. After polishing, the polishing machine main body 41 moves out of the inner ring of the bearing;

[0048] When the inner ring fixer 2 moves to the position of the toggle block 6, the toggle block 6 will squeeze the control toggle rod 26, so that the control toggle rod 26 drives the positioning and fixing block 27 to move horizontally at the position of the limit groove block 28, then the positioning pin 206 is separated from the clamping slider 209, and under the action of the jacking spring 22, the two inner ring jaws 202 are unfolded and no longer clamp the inner ring of the bearing. And when the inner ring fixer 2 moves to the lower position of the processing support frame 1 with the chain conveyor belt 3, the polished inner ring of the bearing drops under the action of gravity to complete the unloading.

[0049] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
