They require delicate operation steps during processing, including fine grinding of their outer angles. However, the existing fine grinding equipment for rolling bearing outer angle processing still has certain defects, such as:

[0003] For example, a bearing ring grinding device with publication number CN210550181U can effectively grind bearing rings of different models by manual adjustment, thereby improving the application range of the grinding device. However, the existing fine grinding device for rolling bearing external angle processing cannot adaptively perform self-fast positioning processing on workpieces between different bearings, and needs to be manually fine-tuned repeatedly, which results in certain limitations in use.

[0035] A first airbag 12 is bonded to the inner side of the docking member 10, and the positions of the first airbag 12 and the fixing rod 11 correspond to each other, and a first air hose 13 is installed through the outer side of the first airbag 12, and an adhesive layer 15 is bonded to the inner side of the edge of the first air hose 13, and a second airbag 14 is docked at the end of the first air hose 13;

[0036] The resisting member 16 has a bearing connected to the outside of the docking member 10, and the inner end of the resisting member 16 is docked with the outer side of the second airbag 14, and the axial end of the resisting member 16 is nested with a second torsion spring 17;

[0037] The third airbag 18 is adhesively connected to the bottom of the base 1, and the third airbag 18 corresponds to the bottom position of the supporting member 3. A connecting member 19 is nested on the outer side of the base 1, and the upper end of the connecting member 19 is butt-jointed with a third traction rope 20 extending upward along the outer side of the base 1. A fine grinding roller 22 is connected to the upper end bearing of the base 1, and the axial end of the fine grinding roller 22 is butt-jointed with the end of the third traction rope 20, and a third torsion spring 21 for resetting is nested on the axial end of the fine grinding roller 22.

[0038] The bearing member 3 forms a nested structure along the upper end of the base 1 through the nesting member 2, and the nesting member 2 is a spherical structure when viewed from the front, and the middle end of the bearing member 3 forms a telescopic support structure with the movable member 23. The connecting shaft 4 is provided with a first torsion spring 401, a first traction rope 402 and a docking handle 403, and the outer side of the shaft end of the connecting shaft 4 is docked with the first torsion spring 401 for resetting, and the outer side of the connecting shaft 4 is nested and docked with the first traction rope 402, while the upper end of the first traction rope 402 is connected to the outer side of the nesting member 2, and the end of the first traction rope 402 is docked with the docking handle 403. The docking handle 403 drives the nesting member 2 through the first traction rope 402 to form a traction mechanism, and the first traction rope 402 cooperates with the connecting shaft 4 and the first torsion spring 401 to form a reset structure. The limiting member 7 forms a traction structure with the movable member 23 through the second traction rope 8, and the limiting members 7 are symmetrically distributed about the center point of the movable member 23, and the symmetrical limiting members 7 form a nested structure through the fixing rod 11.

[0039] The bearing workpiece to be processed is placed vertically on the upper end of the carrier 3. At this time, the pre-stressed movable part 23 will be forced to move downward. At this time, the second traction rope 8 connected to the outer side will drive the connected limiter 7 to stretch the reset spring 6 to move toward each other, thereby self-limiting the nested docking of the middle ends of the contacting workpieces. At the same time, when the two limiters 7 are nested and docked under force, the first airbag 12 at the inner end will be stressed, and then the air will be supplied to the inside of the second airbag 14 on the outside through the first air supply hose 13, so that it is pressurized and expanded to push the outer resistance member 16 to rotate outward. According to the different inner diameters of the bearing workpieces, the self-moving resistance member 16 can adaptively limit the inner end of the bearing workpiece for the second time, while realizing the self-centering of the workpiece to ensure the accuracy of its later grinding.

[0040] The abutment 16 contacts the inflated second airbag 14 to form a rotating structure along the outer side of the docking member 10, and the second airbag 14 is connected to the first airbag 12 through the first air hose 13, and the first airbag 12 forms a pressed structure with the fixing rod 11.

The third airbag 18 is deformed in the process of contacting the bearing member 3, and forms an air supply structure to the inside of the bellows 1802 through the second air hose 1801, and the bellows 1802 pushes the connecting member 19 to form a sliding structure. The fine grinding roller 22 forms a traction structure with the connecting member 19 through the third traction rope 20, and the moving direction of the fine grinding roller 22 is the same as the moving direction of the bearing member 3, and the shaft end of the fine grinding roller 22 forms a quick reset mechanism through the third torsion spring 21.

[0041] The handheld docking handle 403 cooperates with the corresponding first traction rope 402 to drive the spherical nesting part 2 to rotate at a corresponding angle, so that the supporting part 3 of the upper end positioning object moves synchronously. At this time, the supporting part 3 will squeeze the third airbag 18 in contact with the corresponding angle, so that it supplies air to the inside of the bellows 1802 at the end, and then push the connecting part 19 and the third traction rope 20 to move downward, thereby driving the corresponding angle of the fine grinding roller 22 to move at a corresponding angle through the third traction rope 20, so as to accurately allow the user to fine-tune the angle by himself.

[0042] Working principle: When using this movable positioning type rolling bearing external angle processing fine grinding equipment, according to Figure 1-7First, place the device at the position where work is required. The pre-stressed movable member 23 will be forced to move downward. At this time, the second traction rope 8 docked with the outer side will drive the connected limiter 7 to stretch the reset spring 6 to move toward each other, thereby nesting and docking the middle ends of the contacting workpieces to self-limit. At the same time, when the two limiters 7 are nested and docked, the first airbag 12 at the inner end will be stressed, and then the first air supply hose 13 will be used to supply air to the inside of the second airbag 14 on the outside, so that it is pressurized and expanded to push the outer resistance member 16 to rotate outward. According to the different inner diameters of the bearing workpiece, the resistance member 16 that self-moves at an angle can adaptively limit the inner end of the bearing workpiece for the second time, while realizing the self-centering of the workpiece. The user can hold the docking handle 403 and cooperate with the corresponding first traction rope 402 to drive the spherical nesting part 2 to rotate at the corresponding angle, so that the supporting part 3 of the upper end positioning object can move at the same angle. At this time, the supporting part 3 will squeeze the third airbag 18 in contact with the corresponding angle, so that it can supply air to the inside of the bellows 1802 at the end, and then push the connecting part 19 and the third traction rope 20 to move downward, so that the corresponding angle of the fine grinding roller 22 can be driven by the third traction rope 20 to move at the corresponding angle, so that the user can accurately fine-tune the angle by himself. While the program operates the structure, it cooperates with the manual secondary precise operation to meet the processing needs of different angles, thereby increasing the overall practicality.
