Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to a bearing raceway processing device. Background Art

[0002] A bearing generally consists of four parts: an inner ring, an outer ring, rolling elements and a cage. The function of the inner ring is to cooperate with the shaft and rotate with the shaft, the function of the outer ring is to cooperate with the bearing seat, and the rolling elements are evenly distributed between the inner ring and the outer ring with the help of the cage. The cage can make the rolling elements evenly distributed, and the bearing raceway is a general term for the rolling surfaces of all rolling elements. After the inner ring and the outer ring of the bearing are processed, there are often many burrs on the surface of the bearing raceway. Therefore, the raceways of the inner ring and the outer ring need to be polished before the bearing is used. When using the existing bearing raceway surface processing device, it is necessary to adjust the position of the polishing block so that the polishing block is close to the raceway. After use, it is also necessary to adjust the position of the polishing block so that the polishing block is separated from the raceway. When polishing the raceway of the inner ring, it is necessary to frequently adjust the position of the polishing block, which is not conducive to the use of the processing device.

[0003] A Chinese patent with application number CN202210122389.1 discloses a bearing raceway surface processing device, including a grinding module, the grinding module includes a connection frame, the top surface of the connection frame is provided with a fixed disk, the side of the fixed disk is fixedly connected to a clamping module, the top surface of the fixed disk is fixedly connected to a power mechanism for driving the connection frame to rotate, the inner side surface of the connection frame is slidably connected to a sliding plate, and the inner side surface of the connection frame is rotatably connected to an adjustment screw connected to the sliding plate. In the present invention, the return spring 1 is fixedly connected to the sliding block, and when the raceway is polished, under the action of the return spring 1, the grinding block can always be in close contact with the raceway, which is conducive to improving the grinding effect, and after the grinding is completed, the sliding block can be directly opened, and then the inner ring can be removed, and there is no need to frequently adjust the position of the grinding block, which is conducive to the use of the processing device.

[0004] However, when the device in the above patent is grinding the raceway of the inner ring of the bearing, it is unable to cool the inner ring of the bearing.

When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 11 As shown, a bearing raceway processing device of the present invention comprises: a machine table 1, a fixing mechanism 2 for fixing the inner ring of the bearing, a grinding mechanism 3 for grinding the fixed inner ring of the bearing, and a cooling mechanism 4 for cooling the inner ring of the bearing during the grinding process.

[0023] The fixing mechanism 2 includes: a mounting frame 21 fixedly mounted on the machine 1, a linkage plate 22 movably mounted in the mounting frame 21, a power source 23 for driving the linkage plate 22 to move, the power source 23 is fixedly connected to the mounting frame 21, a guide component 28 for limiting the movement of the linkage plate 22, a round rod 24 fixedly mounted on the linkage plate 22, a pressing plate 25 fixedly mounted on the end of the round rod 24, a positioning plate 26 fixedly mounted on the pressing plate 25, and a positioning plate 27 fixedly mounted on the machine 1, wherein the positioning plate 27 is fixedly sleeved on the liquid guide tube 4225; the guide component 28 includes: a guide block 282 fixedly mounted on the linkage plate 22, and a guide rail 281 for guiding the guide block 282 to slide; the guide rail 281 is fixedly connected to the mounting frame 21.

[0024] When fixing the inner ring of the bearing, first place the inner ring of the bearing on the machine table 1 and sleeve it on the positioning plate 27. The positioning plate 27 matches the size of the inner ring of the bearing. Through the setting of the positioning plate 27, the inner ring of the bearing can be positioned, the fixing efficiency of the inner ring of the bearing can be improved, and the displacement of the inner ring of the bearing in the horizontal direction can be avoided.

[0025] At this time, by starting power source 23, the linkage plate 22 is driven to move downward, the linkage plate 22 drives the round rod 24 to move downward, the round rod 24 drives the pressure plate 25 to move downward, and the pressure plate 25 drives the positioning plate 1 26 to move downward. When the pressure plate 25 presses against the top of the bearing inner ring, the positioning plate 1 26 is inserted into the bearing inner ring, and the positioning plate 1 26 matches the size of the bearing inner ring. Through the positioning plate 1 26, the bearing inner ring can be further positioned, thereby improving the fixing efficiency of the bearing inner ring and avoiding the horizontal displacement of the bearing inner ring.

[0026] Through the cooperation between positioning plate 1 26 and positioning plate 2 27, the inner ring of the bearing can be dually positioned, and the positions near the top and near the bottom of the inner ring of the bearing can be positioned, effectively avoiding the horizontal displacement of the inner ring of the bearing, and greatly improving the stability of the inner ring of the bearing during grinding.

[0027] Through the cooperation between the pressing plate 25 and the machine 1, the top and bottom of the inner ring of the bearing can be squeezed and fixed, thereby preventing the inner ring of the bearing from being displaced in the vertical direction, and further improving the stability of the inner ring of the bearing during grinding.

[0028] In the present application, by setting up the fixing mechanism 2, the inner ring of the bearing can be fixed from different directions, which greatly improves the stability of the inner ring of the bearing during grinding, avoids the problem of the inner ring of the bearing affecting the grinding accuracy due to shaking, and improves the production quality of the inner ring of the bearing.

[0029] It is to be added here that the power source 23 is preferably: a cylinder.

[0030] The grinding mechanism 3 includes: a grinding piece 31, a power source 32 for driving the grinding piece 31 to move horizontally, a guide component 2 322 for limiting the horizontal movement of the grinding piece 31, and a rotating component 33 for driving the grinding piece 31 to rotate; the guide component 2 322 includes: a guide block 2 3222 fixedly mounted on the grinding piece 31, and a guide rail 2 3221 for guiding the guide block 2 3222 to slide; the rotating component 33 includes: a movable frame 331 fixedly connected to the power source 32, a driven gear 332 fixedly connected to the movable frame 331, a driving gear 333 meshing with the driven gear 332, and a power source 4 334 for driving the driving gear 333 to rotate; the guide rail 2 3221 is fixedly connected to the movable frame 331.

[0031] Since the grinding mechanism 3 is installed on the linkage plate 22, when the linkage plate 22 moves downward, the grinding mechanism 3 can be driven to move downward, so that when the fixing mechanism 2 completes the fixing of the bearing inner ring, the grinding mechanism 3 is moved to the required horizontal position. Then, through the setting of the fixing mechanism 2, on the one hand, the different positions of the bearing inner ring can be fixed, which greatly improves the stability of the bearing inner ring during grinding, avoids the problem of the bearing inner ring shaking affecting the grinding accuracy, and improves the production quality of the bearing inner ring; on the other hand, when the bearing inner ring is fixed, the grinding mechanism 3 is moved to the required horizontal position.

[0032] When the grinding mechanism 3 reaches the required horizontal position, the grinding piece 31 can be driven to approach the outer side of the inner ring of the bearing by starting the power source three 32. The grinding piece 31 includes: an installation box 311 fixedly connected to the guide block two 3222, a grinding cylinder 313 rotatably installed on the installation box 311, and a power source five 312 for driving the grinding cylinder 313 to rotate; that is, by starting the power source three 32, the grinding cylinder 313 can be driven to stick to the raceway on the outer side of the inner ring of the bearing, and the power source three 32 can drive the grinding piece 31 to move horizontally, so that the grinding depth of the grinding cylinder 313 on the raceway of the inner ring of the bearing can be adjusted, thereby improving the adaptability of use.

[0033] When the power source three 32 can drive the grinding piece 31 to approach the inner ring of the bearing, the grinding piece 31 can drive the guide block two 3222 to slide on the guide rail two 3221. Through the mutual cooperation between the guide block two 3222 and the guide rail two 3221, the grinding piece 31 can be guided and limited, thereby improving the stability of the grinding piece 31 when moving.

[0034] At this time, by starting the power source four 334, the driving gear 333 is driven to rotate, the driving gear 333 drives the driven gear 332 to rotate, the driven gear 332 drives the movable frame 331 to rotate, and the movable frame 331 drives the power source three 32 to rotate, which can drive the grinding piece 31 to rotate, so that the grinding cylinder 313 can rotate along the circumference of the inner ring of the bearing while also rotating, so that the raceway outside the inner ring of the bearing can be fully polished.

[0035] It is to be added here that the power source three 32 is preferably: a cylinder; the power source four 334 is preferably: a motor; the power source five 312 is preferably: a motor.

[0036] The cooling mechanism 4 includes: an external cooling component 41, an internal cooling component 42, a stirring component 43 for stirring the coolant, and a cold source for cooling the coolant in the liquid storage tank.

[0037] It is to be added here that the cold source can be selected as: a refrigeration unit.

[0038] The external cooling component 41 includes: a nozzle 411, and a delivery component 412 for delivering coolant to the nozzle 411; the delivery component 412 includes: a cooling box 4121, a pump body 4122, a liquid inlet pipe 4123 connecting the pump body 4122 and the cooling box 4121, an annular pipe 4125 connected to the nozzle 411, and a liquid outlet pipe 4124 connecting the annular pipe 4125 and the pump body 4122.

[0039] When cooling the outer side of the inner ring of the bearing, by starting the pump body 4122, the coolant in the machine 1 is drawn out through the liquid inlet pipe 4123, and transported to the annular pipe 4125 through the liquid outlet pipe 4124, and then sprayed on the outer side of the inner ring of the bearing through the nozzle 411, thereby cooling the outer side of the inner ring of the bearing, avoiding the problem that a large amount of heat is generated in the inner ring of the bearing during the grinding process, which easily leads to the deformation of the inner ring of the bearing due to heat, and improving the production quality of the inner ring of the bearing.

[0040] It should be added here that there are multiple nozzles 411, which are evenly distributed in a ring shape on the annular tube 4125, so that coolant can be fully sprayed on the polished area on the outer side of the inner ring of the bearing, so that the polished area on the outer side of the inner ring of the bearing is fully cooled, thereby improving the cooling effect on the outer side of the inner ring of the bearing.

[0041] The inner cooling component 42 includes: an annular water bag 421, and a second conveying component 422 for conveying coolant to the annular water bag 421; when the annular water bag 421 expands, it supports the inner ring of the bearing from the inside and cools the inner side of the inner ring of the bearing; the second conveying component 422 includes: a liquid storage tube 4221 fixedly installed on the machine 1, a piston 4222 movably installed in the liquid storage tube 4221, a driving unit 4223 for driving the piston 4222 to move, and a liquid guide tube 4225 connecting the liquid storage tube 4221 and the annular water bag 421; the part of the liquid storage tube 4221 located above the piston 4222 stores coolant, and the part located below the piston 4222 stores air.

[0042] The driving unit 4223 includes: a fixed plate fixedly installed in the cooling box 4121, a threaded rod 42231 rotatably installed on the liquid storage tube 4221 and the fixed plate, a power source 42233 for driving the threaded rod 42231 to rotate, the power source 42233 is fixedly connected to the fixed plate, a threaded tube 42232 threadedly connected to the threaded rod 42231, and a limiting unit 42234 for limiting the threaded tube 42232 when it moves; the threaded tube 42232 is fixedly connected to the piston 4222; the limiting unit 42234 includes: a limiting tube 422341 fixedly installed in the liquid storage tube 4221, the limiting tube 422341 is sleeved on the threaded tube 42232, and a limiting bar 422342 fixedly installed on the threaded tube 42232; a limiting groove is provided in the limiting tube 422341, and the limiting bar 422342 slides in the limiting groove.

[0043] The annular water bag 421 in the present application is made of a soft and durable material (such as latex or silicone) and has good expandability; the annular water bag 421 is in a circular ring shape, and when liquid is injected into the annular water bag 421, the volume of the annular water bag 421 will gradually increase, thereby achieving expansion.

[0044] After the inner ring of the bearing is fixed, the annular water bag 421 is positioned between the positioning plate 1 26 and the positioning plate 2 27. When the annular water bag 421 expands, it is restricted by the positioning plate 1 26 and the positioning plate 2 27, so that the annular water bag 421 can only expand along the circumferential direction of the liquid guide tube 4225, thereby preventing the annular water bag 421 from expanding along the axial direction of the liquid guide tube 4225.

[0045] The setting of positioning plate 1 26 and positioning plate 2 27 in the present application can, on the one hand, play a dual positioning role for the inner ring of the bearing, effectively preventing the inner ring of the bearing from being displaced in the horizontal direction, and greatly improving the stability of the inner ring of the bearing during grinding; on the other hand, it plays a limiting role when the annular water bag 421 collides, so that the annular water bag 421 can only expand along the circumferential direction of the liquid guide tube 4225, thereby preventing the annular water bag 421 from expanding along the axial direction of the liquid guide tube 4225.

[0046] When the inner side of the bearing inner ring is cooled, the power source 42233 is started to drive the threaded rod 42231 to rotate, and the threaded rod 42231 drives the threaded tube 42232 to move. When the threaded tube 42232 moves, the limit bar 422342 can be driven to slide in the limit groove on the limit tube 422341. Through the cooperation between the limit bar 422342 and the limit tube 422341, the threaded tube 42232 can be limited when moving, thereby preventing the threaded tube 42232 from rotating with the threaded rod 42231, and making the threaded tube 42232 move upward along the axial direction of the threaded rod 42231.

[0047] The piston 4222 is driven upward by the threaded tube 42232, and the piston 4222 squeezes the coolant in the liquid storage tube 4221, so that the coolant flows through the liquid guide tube 4225 and enters the annular water bag 421. At this time, the annular water bag 421 expands, and the expanded annular water bag 421 is tightly attached to the inner side of the bearing inner ring, thereby cooling the inner side of the bearing inner ring, avoiding the problem that a large amount of heat is generated in the grinding process of the bearing inner ring, which easily leads to the heat deformation of the bearing inner ring, and further improves the production quality of the bearing inner ring.

[0048] In the present application, the outer cooling component 41 and the inner cooling component 42 cooperate with each other to achieve synchronous cooling of the outer side and the inner side of the bearing inner ring, which has a good cooling effect, prevents the deformation of the bearing inner ring during grinding, and greatly improves the production quality of the bearing inner ring.

[0049] It should be added here that the power source 42233 is preferably: a motor.

[0050] When the expanded annular water bag 421 is tightly attached to the inner side of the bearing inner ring, on the one hand, the inner side of the bearing inner ring is cooled, thereby avoiding the problem that a large amount of heat is generated by the bearing inner ring during the grinding process, which may easily cause the bearing inner ring to deform due to heat, and further improves the production quality of the bearing inner ring; on the other hand, the inner side of the bearing inner ring can be squeezed, thereby supporting the bearing inner ring, further improving the stability of the bearing inner ring during grinding, and preventing the bearing inner ring from shifting and affecting the grinding accuracy.

[0051] The cooling mechanism 4 also includes: a recovery component 44 for recovering the used coolant; the recovery component 44 includes: a collection tank 441 opened on the machine 1, the collection tank 441 is arranged in a ring shape, connecting the collection tank 441 with a through hole 442 in the machine 1, and a plurality of through holes 442 are arranged, which increases the efficiency of the coolant flowing into the cooling box 4121 and filters the used coolant. The filter net 443 is movably installed in the collection tank 441.

[0052] The used coolant mixed with the iron filings generated by grinding the inner ring of the bearing flows into the collecting tank 441, and the coolant can be filtered through the filter screen 443. The filtered coolant flows into the cooling box 4121 through the through hole 442, thereby realizing the recycling of the coolant, improving the utilization rate of the coolant, and saving production costs.

[0053] It is added here that, since the filter screen 443 is movably installed in the collecting tank 441, the filter screen 443 can be easily disassembled, and then the filter screen 443 can be easily cleaned or replaced.

[0054] The stirring assembly 43 includes: an axial stirring unit 431 for axially stirring the coolant, and a fan blade 432 for circumferentially stirring the coolant; the axial stirring unit 431 includes: an air bag 4331, an air guide tube 4332 connecting the air bag 4331 and the liquid storage tube 4221, a movable plate 4333 fixedly installed on the air bag 4331, and a reset unit 4334 for driving the movable plate 4333 to reset; the reset unit 4334 includes: a slide groove provided on the fixed plate, a slider 43341 slidably installed in the slide groove, a fixed rod 43342 for positioning the slider 43341, and a reset spring 43343 for driving the movable plate 4333 to reset; the slider 43341 is fixedly connected to the movable plate 4333; both ends of the fixed rod 43342 are fixedly connected to the slide groove; the fan blade 432 is fixedly sleeved on the threaded rod 42231.

[0055] By setting up a cold source, the coolant in the cooling box 4121 can be cooled, thereby ensuring the cooling effect on the outer side of the inner ring of the bearing, and the liquid storage tube 4221 is immersed in the coolant in the cooling box 4121. When the coolant in the cooling box 4121 is cooled, the coolant in the liquid storage tube 4221 can be cooled, thereby ensuring the cooling effect on the inner side of the inner ring of the bearing.

[0056] By starting the power source 42233, the threaded rod 42231 is driven to rotate, and the threaded rod 42231 drives the threaded tube 42232 to move. Through the cooperation between the limit bar 422342 and the limit tube 422341, the threaded tube 42232 can be limited when moving, thereby preventing the threaded tube 42232 from rotating with the threaded rod 42231, so that the threaded tube 42232 moves along the axial direction of the threaded rod 42231, and the piston 4222 is driven to move through the threaded tube 42232.

[0057] When piston 4222 moves downward, the air in liquid storage tube 4221 can be squeezed into airbag 4331, and airbag 4331 can be driven to expand. The expansion of airbag 4331 can drive movable plate 4333 away from liquid storage tube 4221, and movable plate 4333 can drive slider 43341 to slide in the inner cavity of slide groove, and drive return spring 43343 to compress; when piston 4222 moves upward, the air in airbag 4331 can be sucked into liquid storage tube 4221. At this time, airbag 4331 contracts to a normal state, and movable plate 4333 is driven to approach liquid storage tube 4221. At this time, the elastic force of return spring 43343 can drive slider 43341 to reset, and slider 43341 drives movable plate 4333 to reset. Since airbag 4331 itself has a certain elasticity, movable plate 4333 can also be driven to reset when airbag 4331 is reset, thereby ensuring the reset effect of movable plate 4333.

[0058] Through the reciprocating movement of the movable plate 4333, the coolant in the cooling box 4121 can be axially stirred, so that the coolant produces convection, thereby enabling the coolant to continuously flow and penetrate each other, thereby improving the effect of axial stirring, and further enabling the coolant to be cooled evenly when the cold source cools the coolant, thereby ensuring the cooling effect of the coolant.

[0059] In the present application, the piston 4222 moves upward or downward, which can drive the annular water bag 421 to expand or recover, so as to cool the inner side of the inner ring of the bearing, thereby avoiding the problem that a large amount of heat is generated in the inner ring of the bearing during the grinding process, which may easily lead to the deformation of the inner ring of the bearing due to heat, thereby improving the production quality of the inner ring of the bearing; the inner side of the inner ring of the bearing can be squeezed, thereby supporting the inner ring of the bearing, further improving the stability of the inner ring of the bearing during grinding, and preventing the inner ring of the bearing from shifting and affecting the grinding effect; on the other hand, the movable plate 4333 can be driven to move, thereby realizing axial stirring of the coolant in the cooling box 4121, so that the coolant generates convection, thereby causing the coolant to flow continuously and penetrate each other, thereby improving the effect of axial stirring, and then when the cold source cools the coolant, the coolant is cooled evenly, thereby ensuring the cooling effect of the coolant.

[0060] When the threaded rod 42231 rotates, the fan blades 432 can be driven to rotate. The rotation of the fan blades 432 can achieve circumferential stirring of the coolant, so that the coolant forms a continuous circulation flow in the circumferential direction, so that the coolant can be mixed more fully, and then when the cold source cools the coolant, the coolant is cooled evenly, further ensuring the cooling effect of the coolant.

[0061] In the present application, the stirring component 43 is provided to stir the coolant axially and circumferentially, so that the coolant can be mixed more fully, and then when the cold source cools the coolant, the coolant is cooled evenly, thereby ensuring the cooling effect of the coolant.

[0062] As a further extension of the present application, although the iron filings in the coolant can be filtered through the filter net 443, a small amount of coolant mixed with iron filings will flow into the cooling box 4121, causing pollution to the coolant in the cooling box 4121 and affecting the cooling effect. Therefore, the present application also includes: a connecting spring 5 fixedly installed in the machine 1, and a magnetic rod 6 fixedly installed at the end of the connecting spring 5; the magnetic rod 6 is immersed in the coolant; a plurality of connecting springs 5 ​​and magnetic rods 6 are provided, and are distributed in a circular array in the cooling box 4121; through the provision of a plurality of magnetic rods 6, the iron filings in the coolant can be adsorbed, thereby improving the cleanliness of the coolant and ensuring the cooling effect of the coolant.

[0063] When the stirring assembly 43 stirs the coolant, due to the elastic connection of the connecting spring 5 to the magnetic rod 6, the magnetic rod 6 can swing with the flow of the coolant, thereby expanding the adsorption range of the magnetic rod 6 in the coolant, and the flow of the coolant makes the magnetic rod 6 fully contact with the coolant, thereby improving the adsorption effect of iron filings in the coolant, and greatly improving the cleanliness of the coolant.

[0064] In addition, the movable plate 4333 in the present application can be made of a magnetic material. When the movable plate 4333 moves, on the one hand, it can axially stir the coolant so that the coolant can be more fully mixed, and then when the cold source cools the coolant, the coolant is cooled evenly, thereby ensuring the cooling effect of the coolant; on the other hand, it can adsorb iron filings in the coolant, further improving the cleanliness of the coolant, thereby ensuring the cooling effect of the coolant.

[0065] By setting the magnetic rod 6 and the movable plate 4333, the coolant can be doubly purified, and the magnetic rod 6 and the movable plate 4333 are set up vertically, which can adsorb iron filings in the coolant at different depths, greatly improving the cleanliness of the coolant.
