Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, in particular to a bearing roller positioning grinding device. Background Art

[0002] A bearing is a machine element that limits relative motion to a desired range of motion and reduces friction between moving parts.

[0003] There are many types of bearings, and roller bearings are a more common type. The difference between roller bearings and other bearings is that the rollers inside them are cylindrical in structure, which has good precision and rigidity. In order to reduce the friction coefficient of roller bearings before assembly, the rollers need to be ground. At present, when grinding roller bearings, the two ends of the rollers are usually clamped by a clamping mechanism, and then the rollers are driven to rotate, and the rollers are ground with a grinding device. This processing method is relatively simple and inefficient. Only one roller can be ground in a single operation, which cannot meet production needs when processing large quantities of rollers. At the same time, conventional roller grinding devices can only grind the outer arc surface of the roller. When the fillets at both ends of the roller need to be ground, additional grinding is required, which is very inconvenient. Therefore, there is an urgent need to invent a bearing roller positioning grinding device. Summary of the Invention

[0028] Reference Figures 1-11 A bearing roller positioning and grinding device includes a base 1, a rotating base 2 is rotatably installed on the top of the base 1, a lifting hydraulic cylinder 3 is fixedly installed in the rotating base 2, a supporting tray 4 is fixedly installed on the telescopic end of the lifting hydraulic cylinder 3, a clamping module 8 is provided on the top of the supporting tray 4, a rotating motor 6 is fixedly installed on the top of the supporting tray 4, and a rotating frame 7 is fixedly installed on the output end of the rotating motor 6. The base 1 is used to play a fixing and supporting role. The rotating base 2 can be adjusted to a small angle on the base 1 through the rotating motor, which is convenient for driving the positioned roller to align with the grinding module 13. The lifting hydraulic cylinder 3 is used to push the supporting tray 4 and the clamping module 8 to lift and lower back and forth, and the grinding module 13 can be used to realize the grinding of the roller.

[0029] The top of the base 1 is located on the outside of the rotating base 2 and is fixedly installed with a circular ring-shaped mounting base 9 through several support columns. The top of the mounting base 9 is provided with several evenly distributed mounting grooves 10. A mounting frame 11 is slidably installed in the mounting groove 10. A mounting box 12 is fixedly installed on the top of the mounting frame 11. A grinding module 13 is fixedly installed in the mounting box 12 by bolts. The mounting base 9 cooperates with the mounting groove 10 to connect the mounting frame 11. The mounting frame 11 is slidably connected to the mounting groove 10 through an electric slider. The mounting frame 11 cooperates with the mounting box 12 to push the grinding module 13 to the specified position. When the supporting tray 4 drives the clamping module 8 to rise and fall back and forth, it can drive the roller to contact the corresponding grinding module 13 to achieve grinding.

[0030] The clamping module 8 consists of an upper clamping ring 14 and a lower clamping ring 15. Both the upper clamping ring 14 and the lower clamping ring 15 are circular ring structures. The bottom of the lower clamping ring 15 is fixedly connected to the supporting tray 4 through a number of columns, and the top of the upper clamping ring 14 is fixedly installed above the lower clamping ring 15 through a number of downward-pressing telescopic rods. When placing the bearing rollers, first, the upper clamping ring 14 is raised by operating. At this time, the upper clamping ring 14 is separated from the lower clamping ring 15. At this time, several rollers can be placed on the lower clamping ring 15 in turn. After the placement is completed, the upper clamping ring 14 is operated to descend to the specified position. At this time, several rollers will be clamped between the upper clamping ring 14 and the lower clamping ring 15.

[0031] The upper clamping ring 14 and the lower clamping ring 15 are provided with a plurality of evenly distributed positioning grooves 16 on the side close to each other. The opening positions of the plurality of positioning grooves 16 on the upper clamping ring 14 and the lower clamping ring 15 correspond to each other. A positioning slider 17 is slidably installed in the positioning groove 16, and a support roller 18 is rotatably installed on the outer wall of the positioning slider 17. A positioning rod 19 is fixedly installed on the top of the lower clamping ring 15 and on both sides of the positioning groove 16. An auxiliary sleeve 20 is rotatably installed on the outer wall of the positioning rod 19. A positioning socket 21 is provided on the bottom of the upper clamping ring 14 and on both sides of the positioning groove 16. The top of the positioning rod 19 is inserted in the positioning socket 21. When the roller is placed on the lower clamping ring 1 5, the depression at the bottom of the roller will be inserted into the supporting roller 18. When the upper clamping ring 14 is lowered to the specified position, the supporting roller 18 on the upper clamping ring 14 will be inserted into the depression at the top of the roller. A rubber layer is fixedly installed on the outer wall of the supporting roller 18. The rubber layer can fill the depressions at both ends of the roller when the supporting roller 18 is inserted, thereby increasing the clamping effect of the roller. The positioning rod 19 can limit one end of the roller. When the upper clamping ring 14 is lowered to the specified position, the top of the positioning rod 19 will be inserted into the corresponding positioning socket 21. The auxiliary sleeve 20 on the outer wall of the positioning rod 19 can rotate with the roller, thereby improving the smoothness of the roller rotation.

[0032] An expansion groove 22 is provided on the outer wall of the rotating frame 7, and an expansion airbag 23 is fixedly installed in the expansion groove 22. A number of evenly distributed fixing plates 24 are fixedly installed on the inner wall of the expansion airbag 23. The fixing plates 24 are in an arc-shaped structure. The plurality of fixing plates 24 form a circular ring structure. Elastic tension springs 25 are fixedly installed between the plurality of fixing plates 24. When the upper clamping ring 14 and the lower clamping ring 15 clamp the plurality of rollers, the expansion airbag 23 in the expansion groove 22 can contact the plurality of rollers after expansion. The expanded expansion airbag 23 will push the roller to contact the auxiliary sleeve 20 on the two corresponding positioning rods 19. Since the top and bottom of the roller are respectively plugged into the corresponding support roller 18, the support roller 18 can be driven by the positioning slider 17 to The rollers can be moved in a certain distance between the upper clamping ring 14 and the lower clamping ring 15. At this time, part of the roller will protrude from the upper clamping ring 14 and the lower clamping ring 15. At this time, the rotation of the rotating frame 7 itself can drive several rollers to rotate synchronously. In conjunction with the reciprocating lifting of the supporting tray 4, several rollers can be driven to contact with the grinding module 13 while rotating to achieve grinding. The fixed plate 24 can enhance the friction coefficient between the expansion airbag 23 and the roller, and at the same time avoid contact between the inner ring wall of the upper clamping ring 14 and the lower clamping ring 15 after the expansion airbag 23 is inflated. The expansion airbag 23 is made of elastic material and has a certain elasticity. The elastic tension spring 25 can drive several fixed plates 24 to quickly reset when the expansion airbag 23 contracts.

[0033] A number of evenly distributed expansion and telescopic rods 26 are fixedly installed on the inner wall of the expansion groove 22. The telescopic ends of the expansion and telescopic rods 26 are fixedly connected to the fixed plate 24. The expansion and telescopic rods 26 can push the fixed plate 24 to expand outward by telescoping, thereby realizing the expansion of the expansion airbag 23. At the same time, the friction coefficient between the expansion airbag 23 and the roller can be further improved.

[0034] The grinding module 13 consists of a grinding base 27 and a grinding block 28. The grinding base 27 is fixedly connected to the mounting box 12 by bolts. Two symmetrically arranged telescopic pushing rods 29 are fixedly installed in the grinding base 27. The telescopic ends of the telescopic pushing rods 29 are hinged on the grinding block 28. The end of the grinding block 28 away from the telescopic pushing rods 29 has an arc-shaped structure. The grinding base 27 is used to be fixedly connected to the mounting box 12, and the grinding block 28 is used to grind the roller.

[0035] The top and bottom of the grinding block 28 are both provided with inclined surfaces. When the two telescopic push rods 29 in the grinding base 27 are also in the retracted state, the grinding block 28 is in a vertical state at this time, and the outer wall of the roller protruding from the upper clamping ring 14 and the lower clamping ring 15 can be ground during the lifting and lowering of the clamping module 8. When the clamping module 8 drives the roller to descend to the bottom of the grinding block 28, at this time, the telescopic end of the telescopic push rod 29 located at the top of the grinding base 27 is extended to push the grinding block 28 to tilt. When the clamping module 8 drives the roller to rise, it will drive the top edge of the roller to contact the tilted grinding block 28, so that the top edge of the roller can be ground. When the roller 8 drives the roller to continue to rise, the extended telescopic rod 29 is operated to retract, driving the grinding block 28 to reset to a vertical state, which is convenient for the smooth passage of the roller. When the clamping module 8 drives the roller to rise above the grinding block 28, the telescopic end of the telescopic rod 29 located at the lower part of the grinding base 27 is extended to push the grinding block 28 to tilt in the opposite direction again. When the clamping module 8 drives the roller to descend, the bottom edge of the roller will be driven to contact the tilted grinding block 28, so that the bottom edge of the roller can be ground. When the clamping module 8 drives the roller to continue to descend, the extended telescopic rod 29 is operated to retract, driving the grinding block 28 to reset to a vertical state, which is convenient for the smooth passage of the roller.

[0036] A positioning spring rod 30 is fixedly installed in the positioning slide 16. The telescopic end of the positioning spring rod 30 is fixedly connected to the positioning slider 17. The positioning spring rod 30 can give the positioning slider 17 a reset function. After the roller grinding is completed, when the expansion airbag 23 shrinks, it can drive the roller away from the auxiliary sleeve 20 for easy removal.

[0037] An adjustment slot 31 is provided in the lower clamping ring 15 and below the positioning slot 16. An adjustment slider 32 is slidably installed in the adjustment slot 31. A sensing unit 1 33 is fixedly installed on the top of the adjustment slider 32. A sensing unit 2 34 is fixedly installed on the bottom of the positioning slider 17. A driving screw 35 is rotatably installed in the adjustment slot 31. The driving screw 35 passes through the adjustment slider 32 and is threadedly connected to the adjustment slider 32. A number of evenly distributed adjustment knobs 36 are rotatably installed on the outer wall of the lower clamping ring 15. The adjustment knob 36 is fixedly connected to one end of the driving screw 35. The inflated airbag 23 contacts the roller and pushes the roller The roller plays a certain degree of pushing role, and when the outer diameter of the roller is ground, it will shrink accordingly. At this time, the roller will be further close to the auxiliary sleeve 20 under the push of the expansion airbag 23, and at the same time, it will drive the positioning slider 17 to move. The adjustment knob 36 can be rotated according to processing needs, and the adjustment slider 32 can be driven to move to the specified position by driving the screw 35. When the positioning slider 17 moves to the specified position, it will drive the sensing unit 1 33 and the sensing unit 2 34 to sense each other. At this time, the control unit operates the mounting frame 11 at the corresponding position to move, driving the grinding module 13 away from the corresponding roller to avoid excessive grinding.

[0038] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.
