[0045] Specifically, the switchable binding mechanism includes a regular polygonal frame 10, a plurality of clamping rods 11, a plurality of arc-shaped clips 12 and a plurality of electric push rods 14. The regular polygonal frame 10 is fixedly mounted on the bottom ends of the plurality of fixed arms 9. The plurality of clamping rods 11 are slidably mounted on the inner wall of one side of the corresponding regular polygonal frame 10. Specifically, the plurality of clamping rods 11 are evenly divided into two layers, an upper and a lower layer.

The output ends of the multiple electric push rods 14 are fixedly connected to the top ends of the corresponding clamping rods 11, and the multiple arc-shaped clips 12 are fixedly installed on the bottom ends of the corresponding clamping rods 11. The arc-shaped clips 12 are detachably fixed on the clamping rods 11. The arc-shaped clips 12 of corresponding specifications are replaced according to the size of the automobile bearing. The multiple arc-shaped clips 12 located on the upper layer roughly form a "hoop", and the multiple arc-shaped clips 12 located on the lower layer also roughly form a "hoop". The two "hoops" constitute two upper and lower fixing points for the inner ring or outer ring of the automobile bearing, and reliable fixation can be achieved through a single fixing point.

[0046] In this embodiment:

[0047] In the initial state, the output ends of the multiple electric push rods 14 are all in a retracted state. When in use, the outer ring or inner ring of the automobile bearing is placed between the multiple arc-shaped clips 12, and then the output ends of the multiple electric push rods 14 are started to extend, and the multiple electric push rods 14 will push the corresponding clamping rods 11 to move toward the center of the regular polygonal frame 10, and the clamping rods 11 drive the corresponding arc-shaped clips 12 to move, so that the arc-shaped clips 12 contact the outer ring or inner ring of the automobile bearing, and the multiple arc-shaped clips 12 cooperate to clamp and fix the outer ring or inner ring of the automobile bearing;

[0048] Then, the output ends of the two first hydraulic cylinders 7 are started to retract downward, and the two first hydraulic cylinders 7 drive the lifting plate 5 to slowly descend, and the lifting plate 5 drives the switching type fixing mechanism to move downward, so that the outer ring or inner ring of the automobile bearing can be immersed in the abrasive 3. Then, the first motor 16 is started to run, and the first motor 16 drives the second gear 18 to rotate, and the engagement transmission between the second gear 18 and the first gear 17 drives the rotating drum 8 to rotate, and the rotating drum 8 drives the switching type fixing mechanism to rotate, and the switching type fixing mechanism drives the outer ring or inner ring of the automobile bearing to rotate, and the outer ring or inner ring of the automobile bearing will generate friction with the abrasive 3 during the rotation process, so that the burrs on the surface can be ground off. After a period of time, on the basis of keeping the first motor 16 running, the output ends of the multiple electric push rods 14 located on the upper layer are started to retract a certain distance. The plurality of arc-shaped clips 12 located on the upper layer are separated from the outer ring or inner ring of the automobile bearing, so that the portion originally clamped by the arc-shaped clips 12 of the upper layer can contact the abrasive 3, and then the output ends of the two first hydraulic cylinders 7 are started to extend upward by a certain distance until the arc-shaped clips 12 located on the upper layer rise to the upper part of the abrasive 3, and then the output ends of the plurality of electric push rods 14 located on the upper layer are started to extend, so that the plurality of arc-shaped clips 12 located on the upper layer re-clamp the outer ring or inner ring of the automobile bearing, and then the output ends of the plurality of electric push rods 14 located on the lower layer are started to retract, so that the plurality of arc-shaped clips 12 located on the lower layer are separated from the outer ring or inner ring of the automobile bearing, so that the portion originally clamped by the plurality of arc-shaped clips 12 of the lower layer can contact the abrasive 3, so that the burrs on the outer ring or inner ring of the automobile bearing can be cleaned in all directions;

[0049] After the above-mentioned burr cleaning is completed, the first motor 16 is turned off, and then the output ends of the two first hydraulic cylinders 7 are started to extend, so that the lifting carrier plate 5, the switchable fixing mechanism, etc. are reset upward, and finally the output end of the electric push rod 14 located on the upper layer is started to retract, so that the outer ring or inner ring of the automobile bearing can be released. The outer ring or inner ring of the bearing after the burr cleaning is completed can be taken away.

[0050] Compared with the related art, the automobile bearing surface treatment equipment provided by the present invention has the following beneficial effects:

[0051] Through the arrangement of the material box 2, the abrasive 3, the lifting plate 5, the first hydraulic cylinder 7, the rotating drum 8, the switchable fixing mechanism, the first motor 16 and other components, the switchable fixing mechanism has two fixing points for the outer ring or the inner ring of the automobile bearing. When the first hydraulic cylinder 7 is started, the outer ring or the inner ring of the bearing that has been fixed can be completely put into the abrasive 3. After the first motor 16 is started, the switchable fixing mechanism can be driven to rotate, so that the outer ring or the inner ring of the automobile bearing except the part that is fixed generates friction with the abrasive 3. After the two fixing points of the outer ring or the inner ring of the bearing are switched and fixed by the switchable fixing mechanism, the inner ring or the outer ring of the automobile shaft bearing can be fully cleaned of burrs. By using the automobile bearing surface treatment equipment, the burr cleaning work on the surface of the inner ring or the outer ring of the automobile bearing can be completed at one time, which has the advantages of efficient processing, time saving and simple operation.

[0052] Second embodiment:

[0053] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0054] Please refer to Figure 5-Figure 7 In the automobile bearing surface treatment equipment provided in this embodiment, a second hydraulic cylinder 20 is also fixedly installed on the top of the bottom plate 1, and a feed guide column 19 is installed on the output end of the second hydraulic cylinder 20. The top end of the feed guide column 19 extends into the material box 2, and the feed guide column 19 is movably connected to the material box 2. A circular opening is opened at the bottom of the material box 2, and the diameter of the circular opening is adapted to the diameter of the feed guide column 19. The feed guide column 19 can slide up and down and rotate in the circular opening. In the initial state, the feed guide column 19 is in the highest position, and its top end protrudes from the abrasive 3. When the outer ring or inner ring of the automobile bearing is burred, after the inner ring or outer ring of the bearing is fixed First, the output ends of the two first hydraulic cylinders 7 are started to retract, so that the inner ring or outer ring of the bearing contacts the top of the feed guide column 19, and then the output end of the second hydraulic cylinder 20 is started to retract, so that the feed guide column 19 and the outer ring or inner ring of the bearing descend at the same speed. In this way, the resistance of the outer ring or inner ring of the bearing entering the abrasive 3 can be greatly reduced, and the inner ring or outer ring of the bearing can be prevented from being relatively displaced with the arc-shaped clamping piece 12 due to excessive reverse force. At the same time, excessive friction can also be prevented from being applied to the bottom of the outer ring or inner ring of the bearing. The outer ring or inner ring of the bearing stops after descending a sufficient distance, and the feed guide column 19 then descends a certain distance to distance itself from the outer ring or inner ring of the bearing.

[0055] In this embodiment, in order to ensure that the abrasive 3 can completely cover the outer ring or inner ring of the bearing, a rotating support seat 21 is fixedly installed at the output end of the second hydraulic cylinder 20, and the feed guide column 19 is rotatably installed on the rotating support seat 21. A plurality of L-shaped round rods are fixedly installed on the outer wall of the feed guide column 19, and a rotating push blade 25 is fixedly installed on the top of the plurality of L-shaped round rods. A third gear 22 is fixedly sleeved on the outer wall of the feed guide column 19, a second fixed plate is fixedly installed at the bottom of the rotating support seat 21, and a second motor 23 is fixedly installed on the top of the second fixed plate. A fourth gear 24 is fixedly sleeved on the output end of the second motor 23, and the third gear 22 is meshed with the fourth gear 24. After the feed guide column 19 drops to the lowest position, the second motor 23 is started to run, driving the feed guide column 19 to rotate, and the feed guide column 19 drives the plurality of rotating push blades 25 to rotate, so that the abrasive 3 can be forced to flow, and part of the abrasive 3 will flow to the center position, thereby ensuring that the outer ring or inner ring of the bearing is completely covered by the abrasive 3.

[0056] In this embodiment:

[0057] After the inner ring or outer ring of the bearing is fixed by the switchable fixing mechanism, the output ends of the two first hydraulic cylinders 7 are started to retract, driving the inner ring or outer ring of the bearing to move downward until it contacts the top of the feed guide column 19, and then the output end of the second hydraulic cylinder 20 is started to retract, so that the feed guide column 19 and the outer ring or inner ring of the bearing are descended at the same speed. After the outer ring or inner ring of the bearing descends a sufficient distance, the operation of the first hydraulic cylinder 7 is stopped, and the second hydraulic cylinder 20 continues to operate until the feed guide column 19 descends to the lowest position, so that a distance will be opened between the feed guide column 19 and the outer ring or inner ring of the bearing, and finally the second motor 23 is started to operate, and the second motor 23 drives the feed guide column 19 to rotate, and the feed guide column 19 drives multiple rotating push blades 25 to rotate, and the rotation The moving rotating push blade 25 will force the abrasive 3 in the upper layer to flow, and some abrasives 3 will flow to the center position, so that the outer ring or inner ring of the bearing can be completely covered by the abrasive 3, and then the subsequent burr cleaning work can be carried out; through the arrangement of the feeding guide column 19, the second hydraulic cylinder 20, the rotating support seat 21, the second motor 23, the rotating push blade 25 and other components, the outer ring or inner ring of the bearing can follow the feeding guide column 19 to descend and enter the abrasive 3, which can effectively avoid the relative displacement of the inner ring or outer ring of the bearing with the arc-shaped clamping piece 12 due to excessive reverse force, thereby improving the reliability of the device, and at the same time, it can also avoid the bottom of the outer ring or inner ring of the bearing from being excessively rubbed by the abrasive 3, which is beneficial to the protection of the inner ring or outer ring of the automobile bearing.

[0058] Third embodiment:

[0059] The third embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0060] Please refer to Figure 8-Figure 13 In the automobile bearing surface treatment equipment provided in this embodiment, a side support seat is also fixedly installed on the outer wall of one side of the lifting carrier plate 5, and a blower 26 is fixedly installed on the top of the side support seat. One end of a connecting pipe 27 is fixedly installed at the air outlet of the blower 26. The end of the connecting pipe 27 away from the blower 26 extends into the protective box 15 and is rotatably sealed and connected to the top of the rotating drum 8. After the burr cleaning is completed, the blower 26 is started to blow air into the connecting pipe 27, and finally the wind is ejected from the rotating drum 8 and sprayed toward the inner ring or outer ring of the bearing, so that the abrasive 3 attached to the inner ring or outer ring of the bearing can be blown off.

[0061] In this embodiment, in order to prevent the abrasive 3 from scattering everywhere, an annular groove 201 is opened on the top of the material box 2, and a retaining ring 29 is slidably installed in the annular groove 201. Two fixing ears 30 are fixedly installed on the outer wall of the retaining ring 29. Two support plates 31 are fixedly installed on the bottom of the material box 2. Third hydraulic cylinders 32 are fixedly installed on the top of the two support plates 31. The output ends of the two third hydraulic cylinders 32 are fixedly connected to the corresponding fixing ears 30. Before blowing air onto the outer ring or inner ring of the bearing, the output ends of the two third hydraulic cylinders 32 are started to extend, so that the retaining ring 29 can move upward, and finally the retaining ring 29 can surround the inner ring or outer ring of the bearing. In this way, the blown abrasive 3 will not be scattered everywhere due to the shielding of the retaining ring 29, and will eventually fall back into the material box 2.

[0062] In this embodiment, in order to remove the abrasive 3 on the inner ring or outer ring of the bearing more thoroughly, an air guide cylinder 28 is fixedly installed at the bottom of the rotating drum 8. Specifically, the air guide cylinder 28 includes an outer cylinder 2801, a conical inner cover 2802 and a plurality of fixed rods 2803. The outer cylinder 2801 is fixedly installed at the bottom of the rotating drum 8, the conical inner cover 2802 is arranged in the outer cylinder 2801, and the plurality of fixed rods 2803 are arranged between the conical inner cover 2802 and the outer cylinder 2801. One end of the plurality of fixed rods 2803 is fixedly connected to the inner wall of the outer cylinder 2801, and the other end is fixedly connected to the outer wall of the conical inner cover 2802. After the wind sprayed from the rotating drum 8 enters the air guide cylinder 28, it will be sprayed through the gap between the conical inner cover 2802 and the outer cylinder 2801 in a ring shape. In this way, the wind can be more concentrated and directed to be sprayed onto the inner ring or outer ring of the bearing, so that the abrasive 3 can be removed more thoroughly.

[0063] In this embodiment:

[0064] After the burr cleaning is completed, the output ends of the two third hydraulic cylinders 32 are first started to extend, so that the retaining ring 29 moves upward until the retaining ring 29 surrounds the inner ring or outer ring of the bearing, and then the blower 26 is started to blow air into the connecting pipe 27. The wind in the connecting pipe 27 will enter the rotating drum 8, and then enter the air guide tube 28. Finally, the wind will be sprayed to the inner ring or outer ring of the bearing in an annular shape through the bottom of the air guide tube 28, so that the abrasive 3 attached to the inner ring or outer ring of the bearing can be blown off. The blown-off abrasive 3 is blocked, so it will not be scattered everywhere, and will eventually fall back into the abrasive 3; through the arrangement of the blower 26, the connecting pipe 27, and the air guide tube 28, the abrasive 3 attached to the inner ring or outer ring of the bearing can be better cleaned up, reducing the difficulty of cleaning the inner ring or outer ring of the bearing in subsequent processes; through the arrangement of the retaining ring 29, the fixing ear 30, and the third hydraulic cylinder 32, the inner ring or outer ring of the bearing can be surrounded to prevent the blown-off abrasive 3 from being scattered everywhere, thereby effectively reducing the loss of the abrasive 3.
