Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a positioning device for processing a bearing ring. Background Art

[0002] Bearing rings are parts that connect bearings and bearing seats. They mainly include inner rings and outer rings, as well as many special types of rings, such as tapered inner rings, tapered outer rings, wide inner rings, lock inner rings, lock outer rings, stamped outer rings, etc. These rings are designed according to specific application scenarios and needs to meet different working conditions. Grinding is the final processing in the processing of bearing rings and rollers, called finished product processing. It makes the size accuracy and shape accuracy of the rings meet the design requirements and provide qualified rings for bearing assembly;

[0003] The Chinese publication number is: CN116852260A, which discloses a positioning device for processing bearing rings, including: two mutually hinged support parts; a grabbing part, wherein the grabbing part is located between the two support parts and is used to hook the bearing ring; wherein the support part fits the outer wall of the bearing ring, is used to support the bearing ring, and fixes the bearing ring by cooperating with the grabbing part; a limiting part is connected between the two support parts, and the spacing between the two support parts is maintained by the limiting part. The positioning device for processing bearing rings described in the present invention uses two support parts to support the outer wall of the bearing ring, and then the grabbing part hooks the inner wall of the bearing ring to form a three-point clamping, so it effectively solves the technical problem of the poor application range of the existing bearing ring positioning device when in use, thereby realizing the same clamping of bearing rings of different models;

[0004] Although the above invention can achieve the clamping of different types of bearing rings by three-point clamping of the bearing rings through two supporting parts and a grabbing force, it does not take into account that before the bearing rings are ground, they are generally placed in a designated position by a worker and then positioned and fixed by a positioning device, and then removed by a worker. In this manual conveying and grinding method, on the one hand, the worker is required to position the bearing before grinding or other processes, which is time-consuming and labor-intensive. On the other hand, during positioning, in a specific vertical positioning process, the bearing is prone to tilt, resulting in damage to the bearing during tightening or stretching of the fixture.

[0040] like Figure 1-Figure 3 As shown, a tightening plate 11 is fixedly connected to the top of the conveyor belt 1, a motor No. 2 is fixedly connected to the outer wall of the guard plate 12, a correction roller 21 is fixedly connected to the output end of the motor No. 2, and a transmission belt 211 for making the correction rollers 21 on both sides rotate in the same direction is arranged on the outer wall of the correction roller 21 at one end close to the motor No. 2, the rotating rod 23 as a whole consists of a threaded part 231 and a smooth part 232, and a cross column 241 is arranged in the middle of the contraction plates 24 on both sides, the contraction plate 24 close to the motor No. 2 is fixedly connected to the cross column 241, and the contraction plate 24 away from the motor No. 2 is slidably connected to the cross column 241.

[0041] like Figure 6 As shown, a slope 2431 is provided on the top of the No. 1 sliding block 243 , and a pad 2432 is fixedly connected to the No. 1 sliding block 243 at one side close to the fixing assembly 3 .

[0044] It can be seen that when the bearing needs to be positioned and fixed, and when the bearing ring needs to be ground after the previous process is completed, the bearing ring is conveyed flat by the conveyor belt 1 toward the correction roller 21, and then the tightening plate 11 stably conveys it to the correction roller 21. At this time, the correction roller 21 is in a non-rotating state. After the bearing ring is conveyed to the correction roller 21, it is in a lying state. At this time, the rotating rod 23 rotates under the drive of the second motor 22, and the positioning component 4 slides toward the fixing component 3 under the action of the threaded part 231 of the rotating rod 23, and drives the shrinking plate 24 on this side to also push toward the fixing component 3, and merges the shrinking plates 24 on both sides.

[0045] Embodiment 2

[0046] Different from the first embodiment, in order to realize the vertical fixation of bearing rings of different widths, as Figure 7-Figure 9As shown, the fixing assembly 3 includes a No. 1 support frame 31, the bottom of the No. 1 support frame 31 is fixedly connected to a driving base 35, one side of the driving base 35 is fixedly connected to one side of the retracting plate 24, a No. 1 threaded rod 32 is arranged on the top of the driving base 35, the No. 1 threaded rod 32 is rotatably connected to the No. 1 support frame 31, the middle end outer wall of the No. 1 threaded rod 32 is fixedly connected to a partition 321, the No. 1 threaded rod 32 is divided into an upper half and a lower half by the partition 321, both sides of the No. 1 support frame 31 are fixedly connected to a fixed extension rod 311, one side of the fixed extension rod 311 is slidably connected to a sliding clamp 312, one side of the sliding clamp 312 is fixedly connected to a telescopic rod 313, the telescopic rod 313 is telescopically connected to the fixed extension rod at one end away from the sliding clamp 312 On the inner side of the rod 311, the outer wall of the telescopic rod 313 is sleeved with a spring 314, the upper half of the No. 1 threaded rod 32 is threadedly connected to the No. 1 sliding member 33, and the No. 1 sliding member 33 is rotatably connected to a rotating rod 331 on the side close to the guard plate 12, and the rotating rod 331 is fixedly connected to a No. 2 sliding block 332 at the end away from the No. 1 sliding member 33, and the No. 2 sliding block 332 is fixedly connected to a fixed roller 333 on the side away from the guard plate 12, and the outer wall of the rotating rod 331 is sleeved with a sliding column 334, and the No. 2 sliding block 332 is slidably connected in the sliding column 334, and the sliding column 334 is rotatably connected to the outer wall of the correction roller 21, wherein: the lower half of the No. 1 threaded rod 32 is threadedly connected to the No. 2 sliding member 34, and one side of the No. 2 sliding member 34 is rotatably connected to a downward pressure roller 341.

[0047] Thus, it can be known that after the bearing ring is pushed to the position of the fixed component 3, one side of the bearing ring will be against the fixed extension rod 311. At this time, under the drive of the driving base 35, the No. 1 threaded rod 32 rotates, and the No. 1 threaded rod 32 will drive the No. 1 sliding member 33 and the No. 2 sliding member 34 to slide downward together. In the process of the No. 1 sliding member 33 sliding downward, it will drive the rotating rod 331 and the sliding column 334 to rotate inwardly by a certain angle. At this time, the rotating rod 331 will slide toward the inner side of the lower end of the sliding column 334, and at the same time drive the No. 2 sliding block 332 and the fixed roller 333 to slide downward, press the inner wall of the bearing ring downward, and use The correction roller 21 fixes the bearing ring, and the downward movement of the No. 2 sliding member 34 will drive the downward pressure roller 341 to move downward at the same time, fixing the lower end of the bearing ring on the pad 2432 and the downward pressure roller 341. At this time, the correction roller 21 will drive the bearing ring to rotate under the drive of the No. 1 motor 2, and then grind the bearing ring. This allows the bearing ring to be fixed by the No. 1 support frame 31, the No. 2 support frame 41, the fixed roller 333 and the downward pressure roller 341, and at the same time, the bearing roller can be rotated and ground while being fixed by the rotation of the correction roller 21, and the bearing ring can be prevented from being damaged by collision under the action of each roller.
