Description

Technical Field

[0001] The invention belongs to the technical field of bearing ring grinding, in particular to a grinding machine for machining the inner circle of a horizontal bearing ring. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. In the actual production and processing of bearings, they need to be polished with the help of grinders, especially the inner circle of the bearing ring requires ball rotation, so higher smoothness requirements are required.

[0003] Chinese invention patent CN108000262B discloses a bearing internal cylindrical processing grinder, which fixes the bearings through a bearing fixing seat I and can meet the needs of bearings of different sizes and models. When the grinder is working, the support plate is in close contact with the bottom of the bearing fixing seat I, supporting the bottom of the bearing fixing seat I and preventing damage to the bearing fixing seat I and the connecting plate. The grinding machine has low grinding accuracy and poor grinding effect.

[0004] Chinese invention patent CN108326695B discloses a bearing inner ring grinder, which includes a bed, a feeding mechanism, a loading and unloading mechanism, a workpiece mounting mechanism, a grinding mechanism, and a cleaning mechanism arranged on the bed for cleaning grinding wheel dust waste. The cleaning mechanism includes a spray pipe arranged on the bed and located above the workpiece mounting mechanism, and a collection table arranged on the lower side of the bed. The grinder cannot realize batch grinding production processing.

[0005] When the grinding wheel needs to be installed and fixed on the output end of the grinding motor, if the grinding wheel and the output end of the grinding motor are not coaxial, or impurities are attached to the outer surface of the grinding wheel, the grinding wheel will rotate eccentrically and grind the inner circle of the bearing ring, affecting the grinding effect. In the existing technology, manual inspection and calibration are required, which leads to low detection accuracy and poor detection accuracy.

[0006] In addition, in the prior art, when the grinding wheel and the inner circle of the bearing ring are cooled by means of coolant, the coolant is easy to adhere to the outer surface of the grinding wheel and form water mist. The formation of the water mist can easily cause the grinding wheel to slip during the grinding process, and the debris generated during the grinding process is adsorbed on the outer surface of the grinding wheel under the adsorption force of the water mist. The debris is easy to cause wear after the grinding wheel rotates and contacts the inner circle of the bearing ring. The above processes will reduce the dryness and smoothness of the grinding wheel and cause damage to the grinding of the inner circle of the bearing ring.

[0007] As the grinding wheel rotates and grinds, it wears out and its diameter decreases. If the grinding wheel feed rate is not adjusted in time, the grinding efficiency of the grinding wheel on the inner circle of the bearing ring will also decrease. As the grinding wheel and the inner circle of the bearing ring are continuously grinding, the temperature of the grinding wheel will continue to change, and the strength of the grinding wheel will also change, thereby reducing the durability of the grinding wheel and the stability of the grinding wheel inner circle.

[0008] In view of the above problems existing in the prior art, the present invention provides a grinding machine for machining the inner circle of a horizontal bearing ring. Summary of the Invention

The other end of the refrigerant pipe 408 is connected to the connecting hole 413. Refrigerant gas is provided inside the refrigerant pipe 408. The refrigerant gas generated by the refrigerator flows along the refrigerant pipe 408 into the connecting hole 413 for circulation. The connecting hole 413 is evenly connected to a plurality of exhaust holes 414 on the side close to the grinding wheel 315. The exhaust holes 414 match the outer surface of the grinding wheel 315, and the refrigerant gas inside the connecting hole 413 is discharged along the plurality of exhaust holes 414 and cools the side of the grinding wheel 315 away from the grinding position of the inner circle of the bearing ring. , to avoid the coolant pipe 316 from forming water mist that adheres to the outer surface of the grinding wheel 315 and causes the grinding wheel 315 to slip and reduce the grinding effect, thereby effectively improving the thoroughness of cleaning the outer surface of the grinding wheel 315, a plurality of cleaning brushes 419 are evenly provided on the side wall of the horizontal plate 407 near the grinding wheel 315, and the cleaning brushes 419 and the exhaust holes 414 are symmetrically distributed along both sides of the scraper 411, and the plurality of cleaning brushes 419 and the exhaust holes 414 are staggered. The cleaning brushes 419 cooperate with the scraper 411 to achieve thorough and effective cleaning and scraping off of the impurity water mist attached to the outer surface of the grinding wheel 315, further improving the cleaning effect and ensuring thorough cleaning.

[0055] When it is necessary to clamp and fix the grinding wheel 315 and the output end of the grinding motor 314, due to the circular structure of the grinding wheel 315 itself and the need to rotate for grinding, the concentricity of the grinding wheel 315 and the grinding motor 314 and the smoothness of the outer surface of the grinding wheel 315 directly affect the grinding effect. In the prior art, manual detection and calibration are required, which leads to problems such as low detection precision and poor detection accuracy. At the same time, when the coolant pipe 316 sprays coolant and cools the grinding position of the grinding wheel 315 and the inner circle of the bearing ring, the coolant easily adheres to the outer surface of the grinding wheel 315 to form water mist. As the grinding wheel 315 rotates and grinds the inner circle of the bearing ring, the water mist causes the grinding wheel 315 to slip, thereby reducing the grinding effect. The grinding wheel 315 and the inner circle of the bearing ring form debris when grinding. The debris will adhere to the outer surface of the grinding wheel 315 under the action of its own static electricity and the adsorption force of the water mist. If the debris is not removed in time, the debris will easily cause extrusion damage to the subsequent grinding position of the grinding wheel 315 and the inner circle of the bearing ring, thereby reducing the stability and smoothness of the inner circle of the bearing ring; at the same time, when the grinding wheel 315 is continuously polished, it will be worn out, and the diameter of the grinding wheel 315 itself will be reduced synchronously. If the feed amount of the grinding wheel 315 is not adjusted at this time, the grinding efficiency of the grinding wheel 315 and the inner circle of the bearing ring will be reduced; and as the grinding work of the grinding wheel 315 and the inner circle of the bearing ring is continuously carried out, when the temperature of the grinding wheel 315 changes, the strength of the grinding wheel 315 itself will change synchronously, thereby reducing the durability of the grinding wheel 315 and the grinding stability of the inner circle of the bearing ring.

[0056] In order to solve the above-mentioned problems, when the horizontal bearing ring inner circle processing grinding machine is actually used, the base 101 is first placed in a suitable position, and the base 101 is elastically supported and protected by the buffer pad 102. In the initial state, the adjustment seat 312 is in the initial position, and the distance between the adjustment seat 312 and the rotating disk 207 is much larger than the width of the bearing ring, thereby avoiding the grinding wheel 315 from affecting the clamping of the bearing ring, and the cross plate 407 is synchronously in the initial position, the distance value detected by the distance sensor 410 is at the initial value, and the distance between the cross plate 407 and the axis of the grinding motor 314 is much larger than the radius of the grinding wheel 315, which also avoids the scraper 411 from affecting the installation of the grinding wheel 315.

[0057] Afterwards, the bearing ring is hoisted between multiple arc-shaped magnetic plates 211 with the help of a hoisting assembly. The control panel 106 controls multiple first electric push rods 209 to start simultaneously and drive the slider 210 to move toward each other in the slide groove 208. The slider 210 moves and drives the arc-shaped magnetic plate 211 to move. Multiple arc-shaped magnetic plates 211 move toward each other and clamp and fix the outer surface of the bearing ring. The magnetic attraction of the arc-shaped magnetic plate 211 itself is used to improve the clamping and fixing effect of the bearing ring. At this time, since the multiple arc-shaped magnetic plates 211 move the same distance and clamp and fix the outer surface of the bearing ring together, the bearing ring and the rotating disk 207 are coaxial, thereby improving the subsequent grinding accuracy and grinding stability of the inner circle of the bearing ring.

[0058] After the bearing ring is clamped, the grinding wheel 315 is plugged and fixed to the output end of the grinding motor 314. At the same time, the control panel 106 controls the second electric push rod 403 to start and drives the cross plate 407 to move close to the end of the grinding wheel 315 through the follower rod 404. The cross plate 407 moves and drives the scraper 411 to move. When the end of the scraper 411 is pressed and contacted with the outer surface of the grinding wheel 315, the scraper 411 squeezes the connecting spring 412 and moves close to the inner wall end of the side groove 409. The distance value detected by the distance sensor 410 decreases. When the distance value detected by the distance sensor 410 reaches the set distance preset value, it means that the cross plate 407 has reached the appropriate position, and the scraper 411 and the cleaning brush 419 are tightly pressed and contacted with the outer surface of the grinding wheel 315. The scraper 411 and the cleaning brush 419 can scrape and clean the outer surface of the grinding wheel 315.

[0059] Afterwards, the control panel 106 controls the grinding motor 314 to start and drive the grinding wheel 315 to rotate. The grinding wheel 315 rotates and continuously changes its contact position with the scraper 411. With the help of the scraper 411, the outer surface of the grinding wheel 315 can be scraped and cleaned, further improving the cleanliness of the outer surface of the grinding wheel 315, and avoiding the reduction of grinding accuracy due to impurities when a new grinding wheel 315 is directly polished against the inner circle of the bearing ring.

[0060] And if the grinding wheel 315 is coaxial with the grinding motor 314, when the grinding wheel 315 and the scraper 411 rotate and contact, the position of the scraper 411 will not change, and the distance value detected by the distance sensor 410 will not change and will be equal to the set distance preset value. However, when the grinding wheel 315 and the grinding motor 314 are not coaxial, as the grinding wheel 315 continues to rotate, the contact distance between the grinding wheel 315 and the scraper 411 continues to change, and under the elastic force of the connecting spring 412, the scraper 411 is driven to continuously move inside the side groove 409, and the distance value detected by the distance sensor 410 continues to change. Then the control panel 106 controls the grinding motor 314 to stop rotating and readjust the position of the grinding wheel 315, further improving the installation accuracy and coaxiality of the grinding wheel 315, avoiding eccentric installation of the grinding wheel 315 and reducing subsequent grinding accuracy and grinding effect.

[0061] After the installation and fixation of the grinding wheel 315 is completed, the control panel 106 controls the moving motor 303 to start and drive the screw rod 304 to rotate. The screw rod 304 is threadedly engaged with the nut block 306 and drives the nut block 306 to move back and forth inside the top groove 302. The nut block 306 drives the movable plate 307 to move back and forth above the support seat 301, thereby adjusting the position of the grinding wheel 315 in the front and rear directions. Similarly, the control panel 106 controls the hydraulic push rod 310 to start and drive the limit block 311 to move inside the limit groove 308. The limit block 311 drives the adjustment seat 312 to move back and forth above the movable plate 307, thereby driving the grinding wheel 315 to move back and forth and reach the grinding position, and the specific grinding position is located at the end of the grinding wheel 315 away from the horizontal plate 407.

[0062] When the grinding wheel 315 and the inner circle of the bearing ring are squeezed and contacted with each other, the control panel 106 controls the grinding motor 314 to start and drive the grinding wheel 315 to rotate. At the same time, the drive motor 205 starts and drives the rotating disk 207 to rotate through the transmission shaft 206. The rotating disk 207 drives the bearing ring to rotate through multiple arc-shaped magnetic plates 211, and the rotation direction of the bearing ring is opposite to the rotation direction of the grinding wheel 315, further realizing the contact grinding effect of the grinding wheel 315 on the inner circle of the bearing ring. At the same time, the control panel 106 controls the pump body inside the coolant tank to start, and the coolant in the coolant tank is discharged to the grinding position along the coolant pipe 316 and sprayed. Cooling down, at the same time, the refrigerator starts and discharges the refrigerant gas along the refrigerant pipe 408 and the docking hole 418 to the inside of the connecting hole 413, and initially the sliding plate 417 partially blocks the connecting hole 413, and the refrigerant gas is finally discharged along the exhaust hole 414 and cools the water mist attached to the outer surface of the grinding wheel 315, and cooperates with the cleaning brush 419 to scrape off the water mist, thereby improving the cleanliness and dryness of the outer surface of the grinding wheel 315, avoiding affecting the subsequent grinding, and at the same time using the scraper 411 to scrape off impurities attached to the outer surface of the grinding wheel 315, further improving the cleanliness and smoothness of the grinding wheel 315.

[0063] As the grinding progresses, when debris adheres to the outer surface of the grinding wheel 315, the grinding wheel 315 rotates to the side of the horizontal plate 407 and is squeezed and contacted with the scraper 411. If the debris adsorption strength is low, the scraping effect of the cleaning brush 419 and the scraper 411 can be reduced and quickly removed. If the debris adsorption strength is very high and the cleaning brush 419 and the scraper 411 alone cannot scrape it off, the debris is squeezed and contacted with the scraper 411 and drives the scraper 411 to squeeze the connecting spring 412 along the side groove 409 away from the grinding wheel 315. 5 ends move, the distance value detected by the distance sensor 410 decreases, then the control panel 106 controls the second electric push rod 403 to start and drives the cross plate 407 to move toward the end close to the grinding wheel 315 through the follower rod 404, and when the cross plate 407 moves, it simultaneously drives the internal scraper 411 and the cleaning brush 419 to move, and under the elastic connection action of the connecting spring 412, the elastic squeezing force of the scraper 411 and the cleaning brush 419 on the debris attached to the outer surface of the grinding wheel 315 is increased, thereby further improving the scraping effect of the scraper 411 on the debris.

[0064] At the same time, when the horizontal plate 407 moves, the extrusion force between the scraper 411 and the grinding wheel 315 increases, and the scraper 411 squeezes the connecting spring 412 along the side groove 409 and moves inward a distance that increases, the volume of the side groove 409 decreases, and the expansion material inside the side groove 409 enters the adjustment groove 415 under the action of the extrusion force and pushes the sliding plate 417, the sliding plate 417 squeezes the return spring 416 and moves away from the side groove 409 end, and the sliding plate 417 drives the docking hole 418 to move, and the overlapping area of ​​the docking hole 418 and the connecting hole 413 increases, so the amount of refrigerant gas entering the connecting hole 413 along the refrigeration pipe 408 increases, and the corresponding refrigerant gas inside the connecting hole 413 The discharge volume along the multiple exhaust holes 414 increases, and the refrigerant gas forms a pulsed air flow wave, with the help of the air flow wave, the cleaning brush 419 and the outer surface of the scraper 411 can be cleaned by wind impact, further improving the cleanliness and dust-freeness of the outer surface of the scraper 411 and the cleaning brush 419, avoiding contamination of the outer surface of the scraper 411 and the cleaning brush 419 during long-term use and reducing the subsequent scraping and cleaning effect of the outer surface of the grinding wheel 315. At the same time, the pulsed gas can also perform wind impact on the debris attached to the outer surface of the grinding wheel 315, thereby cooperating with the scraper 411 and the cleaning brush 419 to further improve the scraping and cleaning effect of the debris, and the refrigerant gas is more versatile and more adaptable.

[0065] As the grinding wheel 315 continues to grind and the grinding efficiency remains constant, the inner diameter of the bearing ring continues to increase steadily. The control panel 106 controls the moving motor 303 to work continuously and stably. The moving motor 303 drives the moving plate 307 to move continuously backward through the screw rod 304 and the nut block 306. The moving plate 307 drives the grinding wheel 315 to move continuously backward through the adjustment seat 312 and always maintains the contact grinding depth with the inner circle of the bearing ring, thereby ensuring that the grinding is carried out continuously and stably. However, as the grinding wheel 315 continues to rotate and grind, the grinding wheel 315 will also wear and its diameter will decrease. If the loss of the grinding wheel 315 itself is not taken into account, the contact extrusion force between the grinding wheel 315 and the inner circle of the bearing ring will be reduced, thereby reducing the grinding accuracy.

[0066] When the diameter of the grinding wheel 315 decreases, the position of the cross plate 407 remains unchanged, and the scraper 411 is driven to move closer to the end of the grinding wheel 315 under the elastic force of the connecting spring 412. The scraper 411 always maintains an extruded contact state with the grinding wheel 315, and the distance value detected by the distance sensor 410 increases. The distance increase value is the wear of the grinding wheel 315 itself, and the control panel 106 controls the moving motor 303 to start and drive the screw rod 304 to rotate. The screw rod 304 drives the moving plate 307 to move backward through the threaded engagement with the nut block 306, and the moving plate 307 drives the grinding wheel 315 backward through the adjusting seat 312, and the grinding The grinding extrusion force between the wheel 315 and the inner circle of the bearing ring is restored to the optimal state, and in order to ensure the scraping effect of the scraper 411 and the cleaning brush 419 on the outer surface of the grinding wheel 315, the control panel 106 controls the second electric push rod 403 to start and drives the cross plate 407 to move toward the end of the grinding wheel 315 through the follower rod 404. The cross plate 407 drives the scraper 411 to move through the connecting spring 412. The scraper 411 and the outer surface of the grinding wheel 315 still reach the optimal extrusion scraping force. The distance value detected by the distance sensor 410 reaches the set distance preset value. Repeat the above process to continue scraping and cleaning the outer surface of the grinding wheel 315.

[0067] As the grinding wheel 315 continuously squeezes and grinds with the inner circle of the bearing ring, if the cooling effect of the coolant on the grinding position does not meet the requirements, the temperature of the grinding wheel 315 at the grinding position will continue to rise and cause damage to the grinding position. When the grinding wheel 315 rotates and reaches the end of the horizontal plate 407, if the temperature of the grinding wheel 315 rises, the volume of the expansion material inside the side groove 409 increases, but because the end of the scraper 411 and the outer surface of the grinding wheel 315 are squeezed and contacted with each other, the position of the scraper 411 does not move, and the distance detected by the distance sensor 410 does not change. The internal pressure of the side groove 409 continues to increase, and the extrusion force exerted by the expansion material on the sliding plate 417 continues to increase. The sliding plate 417 squeezes The reset spring 416 moves toward the end away from the side groove 409, and the sliding plate 417 moves, which simultaneously drives the docking hole 418 to move. The overlapping area of ​​the docking hole 418 and the connecting hole 413 increases, and the amount of refrigerant gas inside the refrigeration tube 408 entering the connecting hole 413 along the docking hole 418 increases. The amount of refrigerant gas inside the connecting hole 413 is finally discharged to the outer surface of the grinding wheel 315 along the exhaust hole 414, and the amount of gas increases. With the help of the increased gas amount, the outer surface of the grinding wheel 315 can be cooled and cooled, thereby ensuring that the temperature of the outer surface of the grinding wheel 315 is always at a suitable temperature, avoiding damage to the grinding position when the grinding wheel 315 is continuously grinding and the temperature continues to rise, and effectively improving the grinding accuracy and grinding quality.

[0068] As the discharge volume of the refrigerant gas inside the exhaust hole 414 changes, and the positions of the scraper 411 and the cleaning brush 419 do not change, the wind cleaning efficiency of the outer surface of the scraper 411 and the cleaning brush 419 by the refrigerant gas is improved, and the pulse gas circulation is realized in conjunction with the continuous change in the discharge volume of the refrigerant gas, thereby further improving the cleaning of water mist or debris attached to the outer surface of the grinding wheel 315, and improving the dryness and smoothness of the outer surface of the grinding wheel 315.

[0069] When the grinding is completed, the grinding of the inner circle of the bearing ring meets the requirements. At this time, the control panel 106 controls the grinding motor 314 to stop working, and the second electric push rod 403 moves in the opposite direction and drives the cross plate 407 to move in the opposite direction through the follower rod 404 to return to its original position. At the same time, the moving motor 303 and the hydraulic push rod 310 both move in the opposite direction to drive the adjustment seat 312 to return to its original position. The hoisting setting fixes the outer surface of the bearing ring. The first electric push rod 209 starts in the opposite direction and drives the slider 210 to return to its original position. The slider 210 drives multiple arc-shaped magnetic plates 211 to return to their original position. The arc-shaped magnetic plates 211 cancel the clamping and fixation of the outer surface of the bearing ring. Replace the new bearing ring and repeat the above process.

[0070] The grinding machine has high grinding precision, good grinding effect and high grinding efficiency for the inner circle of the bearing ring, meets the actual grinding needs for the inner circle of the bearing ring, has strong adaptability, high stability, simple operation and guarantees batch grinding production requirements; at the same time, the axis of the grinding wheel 315 can be adjusted before grinding to ensure that the grinding wheel 315 and the grinding motor 314 are coaxially arranged, and the outer surface of the grinding wheel 315 can be pre-cleaned to avoid contamination during the subsequent grinding of the inner circle of the bearing ring, thereby improving the grinding precision and grinding effect of the grinding wheel 315; during the grinding process, the outer surface of the grinding wheel 315 can also be scraped and cooled to avoid water mist generated when the coolant cools the grinding position and causes grinding The wheel 315 slips, and debris generated after grinding causes damage to the grinding position, thereby improving the dryness and smoothness of the grinding; and as the grinding continues, when the diameter of the grinding wheel 315 changes, it is accurately detected with the help of the scraper 411, and the position of the grinding wheel 315 is subsequently adjusted to ensure that the grinding wheel 315 continues to perform the grinding process accurately; when the grinding wheel 315 is continuously grinding and the temperature rises, the amount of refrigerant gas discharged through the exhaust hole 414 increases accordingly, thereby cooling the grinding wheel 315, ensuring that the temperature of the grinding wheel 315 is at an appropriate temperature at all times, and effectively improving the grinding accuracy and grinding stability of the grinding wheel 315.
