Description

Technical Field

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

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. In other words, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during transmission. Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface.

[0003] The bearing includes an outer ring and an inner ring. In the production process of the bearing, in order to ensure the smoothness of the bearing and suitability for installation, the outer side of the outer ring needs to be polished. At present, conventional bearing polishing devices require manual loading and unloading and clamping, with a low degree of automation, and usually adjust the grinding degree of the bearing by controlling the feed amount of the polishing wheel. However, the polishing wheel wears during use. This control method will cause errors in the grinding process of the bearing, which is not conducive to the use of bearings that require high-precision processing.

[0024] 1.

[0025] 2. In the present invention, a novel automatic polishing device for bearing processing is described. By starting a driving motor, a polishing motor and an electric push rod, the output shaft of the driving motor drives the active pulley to rotate, the active pulley drives the driven pulley and the rotating drum to rotate through a belt, the rotating drum drives the outer ring of the bearing to rotate, the polishing motor drives the polishing wheel to rotate, and the rotation speed of the polishing wheel is opposite to that of the outer ring of the bearing.

As the outer ring of the bearing is ground, the slide plate gradually moves downward under the action of the compression spring, and drives the trapezoidal plate to move downward through the connecting rod. When the trapezoidal plate contacts the wedge plate, the wedge plate is pushed to move leftward and the control button is pressed.

The higher polishing wheel speed can make the abrasive grains contact the workpiece surface more frequently, thereby refining the surface and improving the polishing quality. At the same time, the lower feed speed ensures a more delicate polishing process, reducing scratches or unevenness caused by too fast feed. The higher relative linear speed between the polishing wheel and the outer ring of the bearing can make the abrasive grains leave finer scratches on the workpiece surface, thereby improving the polishing fineness. When the trapezoidal plate contacts the stop button, the controller controls the output end of the electric push rod to contract, thereby driving the polishing wheel to move downward to complete the polishing work;

[0027] 4. In the present invention, the novel automatic polishing device for bearing processing controls the driving motor to stop running and controls the output end of the first cylinder to contract, thereby driving multiple clamping plates to approach each other and release the clamping, and then controls the cooperation between the feeding mechanism and the clamp to realize automatic clamping and unloading of the polished bearing outer ring;

[0028] 5. In the present invention, the novel automatic polishing device for bearing processing can realize automatic fixing and loading and unloading of the bearing outer ring through the cooperation of the material rack, feeding mechanism and clamp, and realize automatic polishing processing in cooperation with the polishing mechanism. At the same time, the polishing parameters can be controlled by the abutment wheel through the cooperation with the linkage mechanism, and the control is more accurate.

The sliding frame 609 drives the driving plate 607 and the piston plate 605 to move up and down by cooperating with the guide rail 404. The conduction direction of the four one-way valves 606 is from left to right, so that when the piston plate 605 moves up and down and causes the upper and lower spaces of the compression box 601 to change alternately, water can be introduced from the water inlet pipe 604 into the water outlet pipe 602, and sprayed out from the cooling nozzle 603, thereby realizing the cooling of the bearing and the polishing wheel 401;

[0063] The compression spring 502 and the slide plate 501 are arranged so that the abutment wheel 5 can maintain the abutment with the outer ring of the bearing. As the outer ring of the bearing is ground, the slide plate 501 gradually moves downward under the action of the compression spring 502, and drives the trapezoidal plate 504 to move downward through the connecting rod 503. When the trapezoidal plate 504 contacts the wedge plate 20, it pushes the wedge plate 20 to move left and presses the control button 18. When the control button 18 is pressed, the signal is transmitted to the controller 10. The controller 10 controls the speed of the driving motor 303 and the polishing motor 405 to increase, and controls the feed speed of the electric push rod 402 to decrease, thereby increasing the cutting frequency of the abrasive particles, thereby having It helps to reduce the roughness value of the workpiece surface. The higher speed of the polishing wheel 401 can make the abrasive particles contact the workpiece surface more frequently, thereby refining the surface and improving the polishing quality. At the same time, the lower feed speed ensures that the polishing process is more delicate, reducing scratches or unevenness caused by too fast feed. The higher relative linear speed between the polishing wheel 401 and the outer ring of the bearing can make the abrasive particles leave finer scratches on the workpiece surface, thereby improving the polishing fineness. When the speed of the driving motor 303 is increased, the frequency of the up and down movement of the piston plate 605 can also be increased, thereby increasing the water spraying speed of the cooling nozzle 603 to improve the cooling effect and meet the requirements of fine polishing.

[0064] When the trapezoidal plate 504 contacts the stop button 19, the controller 10 controls the output end of the electric push rod 402 to contract, thereby driving the polishing wheel 401 to move downward to complete the polishing work;

[0065] By controlling the driving motor 303 to stop running and controlling the output end of the first cylinder 16 to contract, the multiple clamping plates 11 are driven to approach each other to release the clamping, and then the feeding mechanism 8 and the clamp 9 are controlled to cooperate to realize the automatic clamping and unloading of the polished bearing outer ring;

[0066] In this embodiment, the linkage mechanism is set to adjust the polishing parameters according to the movement of the abutment wheel 5, so that the normal polishing speed and feed speed can be used when the trapezoidal plate 504 is not in contact with the wedge plate 20. After the trapezoidal plate 504 is in contact with the wedge plate 20, it indicates that the required grinding degree is about to be reached. At this time, the control button 18 and the controller 10 can cooperate to increase the rotation speed of the polishing wheel 401 and the outer ring of the bearing and reduce the feed speed of the polishing wheel 401, so as to perform fine polishing, which not only ensures the polishing fineness, but also avoids the problem of too long time consumption, and at the same time has the effect of energy saving. The stop button 19 controls the polishing work to stop according to the movement of the abutment wheel 5, and the abutment wheel 5 can be made of wear-resistant material. It is manufactured so that when in use, it rotates with the outer ring of the bearing, so that the relative movement speed between the outer ring of the bearing and the abutment wheel 5 is small and negligible, and therefore the grinding it receives is also very small, thereby ensuring the accuracy of the control of the size of the outer ring of the bearing. It should be noted that in order to conveniently reflect the relevant structure in the accompanying drawings, the distance between the trapezoidal plate 504, the wedge plate 20 and the stop button 19 is shown to be larger, while the grinding amount of the outer ring of the bearing is relatively small during actual processing. The trapezoidal plate 504, the wedge plate 20 and the stop button 19 are actually very small, thereby meeting the actual processing requirements and avoiding waste of materials. This embodiment mainly provides a way of controlling polishing parameters, so that the polishing of the bearing can be achieved more accurately and the yield rate can be improved.
