[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model provides a technical solution: a bearing ring processing device for bearing production and processing, including a worktable 1, a placement frame 2 rotatably connected to the top of the worktable 1 via a bearing and a rotating shaft, a first clamping mechanism 3 is provided inside the placement frame 2, and the first clamping mechanism 3 is located at the top of the worktable 1, a pair of support plates 5 are fixedly connected to the top of the worktable 1, and telescopic cylinders 4 are fixedly connected to the top of each pair of support plates 5, a motor 6 is fixedly connected to one end of the telescopic cylinder 4 located on one side, and a mounting plate 7 is fixedly connected to the output end of the motor 6, and a second clamping mechanism 8 is provided at one end of the telescopic cylinder 4 located on the other side, and the second clamping mechanism 8 is located on one side of the placement frame 2.
[0024] According to the overall structure of the device, when the inner wall or end face of the bearing ring needs to be processed, the bearing ring is placed on the placement frame 2 and its outer wall is clamped and fixed by the first clamping mechanism 3. However, when the outer wall of the bearing ring needs to be processed, the clamping method of the first clamping mechanism 3 will hinder the processing of the outer wall. At this time, the telescopic cylinder 4 on the other side drives the second clamping mechanism 8 to clamp and fix the inner wall of the bearing ring, so as to facilitate the processing of the outer wall of the bearing ring. The switching between the first clamping mechanism 3 and the second clamping mechanism 8 can satisfy the clamping and fixing of the outer wall, inner wall or end face of the bearing ring during processing, without the need for cumbersome disassembly and replacement, reducing time waste and improving the processing efficiency of the bearing ring. Then, the processing tool corresponding to the processing method is installed on the mounting plate 7, and the telescopic cylinder 4 on one side drives the motor 6 and the processing tool to move towards the bearing ring until the processing tool contacts the bearing ring. Then, under the drive of the motor 6, the bearing ring is processed.
[0025] like Figure 1 and Figure 2 As shown, the first clamping mechanism 3 includes a first bidirectional electric telescopic rod 301. The bottom end of the first bidirectional electric telescopic rod 301 is fixedly connected to the inner bottom end of the placement frame 2 through a pair of vertical plates. Both ends of the first bidirectional electric telescopic rod 301 are fixedly connected to movable sleeve blocks 302, and the top end of the movable sleeve blocks 302 is fixedly connected to a movable plate 304. A pair of straight guide grooves 305 are chiseled in the inner top end of the placement frame 2, and the top end of the movable plate 304 passes through the straight guide grooves 305 and extends to its top. The ends of the pair of movable plates 304 that are close to each other are fixedly connected to clamping plates 306. A pair of round rods 303 are fixedly connected between the inner walls of the placement frame 2. A pair of round holes are chiseled in the outer wall of the movable sleeve blocks 302, and the movable sleeve blocks 302 are sleeved between the outer walls of the pair of round rods 303 through the pair of round holes.
[0026] With the first clamping mechanism 3 in place, the first bidirectional electric telescopic rod 301 pulls a pair of movable sleeve blocks 302 to move towards each other along a pair of round rods 303, which in turn causes a pair of movable plates 304 to move towards each other along a pair of guide straight grooves 305, thereby causing a pair of clamping plates 306 to move towards each other and clamp and fix the outer wall of the bearing ring, so as to satisfy the clamping and fixing during the processing of the inner wall or end face of the bearing ring.
[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the second clamping mechanism 8 includes a connecting plate 801. One end of the connecting plate 801 is fixedly connected to one end of the telescopic cylinder 4 located on the other side. A second bidirectional electric telescopic rod 802 is fixedly connected to one end of the connecting plate 801 near the placement frame 2. A pair of pressing blocks 803 are slidably connected to one end of the connecting plate 801 near the placement frame 2. The ends of the pair of pressing blocks 803 that are close to each other are fixedly connected to the two ends of the second bidirectional electric telescopic rod 802. A slider 804 is fixedly connected to one end of each pair of pressing blocks 803 near the connecting plate 801. A pair of sliding grooves 805 are chiseled on one end of the connecting plate 801 near the placement frame 2. The slider 804 is located in the sliding grooves 805 and is slidably connected to them.
[0028] With the second clamping mechanism 8 in place, the telescopic cylinder 4 on the other side pushes the connecting plate 801 toward the bearing ring, causing a pair of extrusion blocks 803 to extend into the bearing ring. It also drives the second bidirectional electric telescopic rod 802 to move apart, causing the pair of extrusion blocks 803 to come into contact with the inner wall of the bearing ring and be extruded and fixed, so as to satisfy the clamping and fixing during the processing of the outer wall of the bearing ring.
[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the inner walls of a pair of clamping plates 306 are provided with anti-slip textures, and the outer walls of a pair of extrusion blocks 803 are provided with anti-slip textures.
[0030] The anti-slip texture makes the clamping plate 306 and the pressing block 803 more secure and stable when clamping and fixing the bearing ring.
[0031] like Figure 5 As shown, a slide cylinder 9 is fixedly connected to the inner top of the workbench 1. A rack plate 11 is fixedly connected to the output end of the slide cylinder 9, and a gear 10 is meshed with one end of the rack plate 11. The top end of the gear 10 is fixedly connected to the rotating shaft at the bottom of the placement frame 2.
[0032] The slide cylinder 9 drives the rack plate 11 to move, which in turn drives the gear 10 to rotate 180°, so as to drive the placement frame 2 to rotate 180°, so as to switch the machining end face of the bearing ring.
[0033] Working principle: When the outer wall of the bearing ring needs to be processed, the telescopic cylinder 4 on the other side pushes the connecting plate 801 towards the bearing ring, causing a pair of pressing blocks 803 to extend into the bearing ring. This drives the second bidirectional electric telescopic rod 802 to move apart, causing the pair of pressing blocks 803 to contact the inner wall of the bearing ring for pressing and fixing. Then, a processing tool corresponding to the processing method is installed on the mounting plate 7. The telescopic cylinder 4 on one side drives the motor 6 and the processing tool towards the bearing ring until the processing tool contacts the bearing ring. Then, driven by the motor 6, the bearing ring is processed. When processing the inner wall or end face of the bearing ring is required, the bearing... The bearing ring is placed on the placement frame 2. The first bidirectional electric telescopic rod 301 pulls a pair of movable sleeve blocks 302 to move towards each other along a pair of round rods 303, causing a pair of movable plates 304 to move towards each other along a pair of guide straight grooves 305, causing a pair of clamping plates 306 to move towards each other, clamping and fixing the outer wall of the bearing ring. The motor 6 then drives the corresponding processing tool to process it. During the processing of the bearing ring end face, after the end face of one side is processed, the slide cylinder 9 drives the rack plate 11 to move, causing it to drive the gear 10 to rotate 180°, so as to drive the placement frame 2 to rotate 180°, switching the end face of the other side to correspond with the processing tool, so that the processing tool can process the end face of the other side.
[0034] The wiring diagrams for the telescopic cylinder 4, motor 6, first bidirectional electric telescopic rod 301, second bidirectional electric telescopic rod 802, and slide cylinder 9 in this solution are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected based on actual use. Therefore, the control methods and wiring layouts for the telescopic cylinder 4, motor 6, first bidirectional electric telescopic rod 301, second bidirectional electric telescopic rod 802, and slide cylinder 9 will not be explained in detail.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
