DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0025] Reference Figures 1 - 3 A grinding tool for grinding a gearbox bearing, comprising a workbench 1, a driving mechanism mounted on the workbench 1, a feeding mechanism, a grinding mechanism and a material taking mechanism, the driving mechanism comprising a toothed disc 2, a gear 3, a motor 4 and a rotating disc 5, the toothed disc 2 is rotatably mounted on the workbench 1, the rotating disc 5 is fixed on the toothed disc 2, the gear 3 is mounted at the output end of the motor 4 and is meshed and connected to the toothed disc 2;

[0026] The feeding mechanism is installed on the upper side of the workbench 1, including a fixed frame 6, a bearing cylinder 7, a cylinder 8 and a push seat 9. The bearing cylinder 7 is installed on the fixed frame 6, the cylinder 8 is installed in the middle of the fixed frame 6, and the push seat 9 is installed at the output end of the fixed frame 6;

[0027] The grinding mechanism is installed on the upper side of the workbench 1, and includes a second fixing frame 10, a second motor 11, a first lead screw 12, a first moving seat 13, a third motor 14, and a grinding disc 15. The second motor 11 is installed on the second fixing frame 10. The first lead screw 12 is fixed at the output end of the second motor 11. The first moving seat 13 is in transmission connection with the first lead screw 12 and moves up and down along the sliding column inside the second fixing frame 10. The third motor 14 is installed on the first moving seat 13, and the grinding disc 15 is installed at the output end of the third motor 14;

[0028] The material taking mechanism is installed on the lower side of the workbench 1, and includes a third fixing frame 18, a fourth motor 19, a second lead screw 20, a second moving seat 21, a fifth motor 22, a third lead screw 23, a third moving seat 24, a rotating seat 25, and a bearing column 26. The fourth motor 19 is installed in the middle of the third fixing frame 18. The second lead screw 20 is installed at the output end of the fourth motor 19. The second moving seat 21 is in transmission connection with the second lead screw 20 and slides along the slide rail on the third fixing frame 18. The fifth motor 22 is installed at the top end of the second moving seat 21. The third lead screw 23 is installed at the output end of the fifth motor 22. The third moving seat 24 is in transmission connection with the third lead screw 23 and moves up and down along the sliding column on the second moving seat 21. The rotating seat 25 is rotatably installed on the second moving seat 21 and is limited by a pin shaft 27. Two bearing columns 26 are oppositely installed on the rotating seat 25;

[0029] The rotating disc 5 is an overall disc mechanism. To ensure the normal pushing of the bearing, the front part of the first fixing frame 6 is an arc structure, which is set to be adapted to the radian of the rotating disc 5. At the same time, to facilitate the normal rotation of the rotating disc 5, when one of the placement grooves 501 moves to correspond to the feeding end of the first fixing frame 6, the other placement groove 501 is directly below the grinding disc 15, and the third one is directly above one of the bearing columns 26.

[0030] A positioning component is also installed at the lower end of the second fixing frame 10. The positioning component includes a second cylinder 16 and a pressing end 17. The second cylinder 16 is installed on the second fixing frame 10, and the pressing end 17 is installed at the output end of the second cylinder 16; after the bearing moves to directly below the grinding disc 15, the second cylinder 16 is driven to push the pressing end 17 to apply pressure to the bearing, so that the bearing is limited in the placement groove 501. And the top surface height of the pressing end 17 is set to be lower than the top surface height of the rotating disc 5. The bearing protrudes from the placement groove 501. When the grinding disc 15 grinds the bearing, the rotating disc 5 and the pressing end 17 will not affect the normal grinding of the bearing.

[0031] At least three placement grooves 501 are formed on the rotating disc 5, which are arranged at equal angles. The width of the upper half of the placement groove 501 is adapted to the diameter of the bearing, and the width of the lower half is adapted to the diameter of the bearing column 26; the bearing can be normally pushed to the upper half of the placement groove 501. After the bearing processing is completed, the bearing column 26 moves upward, passes through the placement groove 501 and the bearing, so as to facilitate the removal of the bearing from the placement groove 501.

[0032] The pushing seat 9 is slidably arranged in contact with the fixing frame 1-6, and one end of the pushing seat 9 is provided with a baffle, and the other end and the bottom are open, and the opening width is greater than the width of the first cylinder 8; after the piston rod of the first cylinder 8 contracts, the pushing seat 9 can slide to the position of the first cylinder 8. At this time, the bottom of the bearing cylinder 7 is not blocked by the pushing seat 9 and drops from the bearing cylinder 7 onto the fixing frame 1-6. Then, the first cylinder 8 can be driven to push the pushing seat 9 to push the bearing to move into the placement groove 501. (It should be noted that the top surface height of the pushing seat 9 is set lower than the upper end surface of the bearing); the bearing cylinder 7 is fixed to the two side plates of the fixing frame 1-6 through the support plate, and its bottom is set higher than the height of the bearing. After the bearing drops from the bearing cylinder 7, it will not affect the normal pushing of the bearing and ensure the normal feeding.

[0033] Working principle: Multiple bearings can be placed in the bearing cylinder 7 in advance, and then the first cylinder 8 can be driven to push the pushing seat 9 to push the lowermost bearing into a placement groove 501 of the rotating disk 5. The driving motor 1-4 drives the toothed disk 2 to rotate through the gear 3, and the toothed disk 2 drives the rotating disk 5 to rotate synchronously. At this time, the placement groove 501 with the bearing is conveyed directly below the grinding disk 15. The second cylinder 16 is driven to push the pressing end 17 to position the bearing in the placement groove 501. At this time, the second driving motor 11 drives the moving seat 1-13 to move downward along the sliding column inside the fixing frame 2-10 through the first lead screw 12, and the third driving motor 14 is driven until the grinding disk 15 is in contact with the end face of the bearing, and then the end face of the bearing can be polished;

[0034] After the bearing is polished, it is rotated by the rotating disk 5 to the material taking mechanism, so that the placement groove 501 is directly above one group of the second cylinders 16. At this time, the fifth driving motor 22 can be driven to drive the moving seat 3-24 to move upward along the slide rail installed on the moving seat 2-21 through the third lead screw 23, so that the corresponding group of bearing columns 26 pass through the placement groove 501 and through the middle of the bearing. At this time, the fourth driving motor 19 drives the moving seat 2-21 to move along the slide rail on the fixing frame 3-18 through the second lead screw 20, so that the bearing column 26 pulls out the bearing at the placement groove 501. At this time, the bearing drops onto the bearing column 26 for collection;

[0035] When one group of the bearing columns 26 collects a certain amount of bearing shafts, the pin shaft 27 can be removed from the rotating seat 25, the rotating seat 25 is rotated to exchange the positions of the two bearing columns 26, and then the pin shaft 27 is inserted into the rotating seat 25 and the moving seat 2-21, and the bearing can be removed from the bearing column 26; this device is convenient for feeding, grinding treatment, and automatic collection.

[0036] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
