[0033] Specifically, when the clamping device is used, the shaft outer ring 18 is placed in the space between the plurality of arc plates 6 and the clamping plate 13 on the top of the hollow cylinder 3. At this time, the threaded rod 7 is rotated. Since the threaded rod 7 is rotatably connected to the top of the hollow cylinder 3 and the bottom end thereof is threadedly connected to the pressing block 8, rotating the threaded rod 7 will cause the pressing block 8 to move upward in the hollow cylinder 3. During the upward movement of the pressing block 8, the sliding blocks 5 located in the sliding grooves 4 will be extruded. Since the sliding blocks 5 are slidable in the sliding grooves 4 and the outer wall thereof is rotatably connected to the arc plates 6, the extrusion of the pressing block 8 will cause the plurality of sliding blocks 5 to slide outward along the sliding grooves 4, thereby driving the plurality of arc plates 6 to open outward, preliminarily fixing the shaft outer ring 18 from the inside. At the same time, after the shaft outer ring 18 is placed, a certain pressure is generated on the two clamping plates 13. Since the two clamping plates 13 are connected to the telescopic rods 10 in the moving grooves 9 on the top of the workbench 1 through the moving blocks 11, respectively, the moving blocks 11 will move inward along the moving grooves 9, the telescopic rods 10 are compressed, the two clamping plates 13 are close to the shaft outer ring 18, and during the approach of the clamping plate 13 to the shaft outer ring 18, the clamping side plates 17 are subjected to the reaction force of the shaft outer ring 18, so that the moving column 16 pulls the spring 15 outward from the circular groove 14, the plurality of clamping side plates 17 are further stably clamped from the side of the shaft outer ring 18, and finally the shaft outer ring 18 is firmly fixed to facilitate subsequent machining operation. The stable and straight movement of the moving block 11 is realized, so as to ensure that the clamping plate 13 can accurately clamp and position the shaft outer ring 18.
[0034] With reference to Figure 1 And Figure 5 The recycling mechanism 2 comprises a connecting frame 201 which serves to support and connect. The top of the plurality of connecting frames 201 is fixedly connected to the bottom of the workbench 1, so as to stably connect the recycling mechanism 2 and the workbench 1. The front side of the connecting frame 201 is provided with a sliding opening 202 which serves as a sliding track for the recycling box 203. The recycling box 203 is slidably connected in the sliding opening 202 and is used to collect the waste generated during machining. The top of the workbench 1 is provided with a recycling groove 204 on the front and rear sides. The recycling groove 204 can guide the machining waste to be concentrated. The adjacent side of the two recycling grooves 204 is provided with a discharging opening 205 at the bottom. The discharging opening 205 facilitates the waste to fall from the recycling groove 204 into the recycling box 203. The front side of the recycling box 203 is fixedly connected with an observation window 25 at the left end. The observation window 25 is convenient for the operator to observe the waste collection in the recycling box 203. The outer wall of the observation window 25 is fixedly connected with a protective shell 26 which serves to protect the observation window 25;
[0035] Specifically, when the bearing outer ring machining is started, various types of machining waste will accumulate on the workbench 1. Since the top of the workbench 1 is provided with recycling grooves 204 on the front and rear sides, the waste will gradually slide into the recycling grooves 204 due to gravity and mechanical vibration during the machining process. The recycling grooves 204 are designed at a specific inclination angle to facilitate the concentration of waste. On the bottom of the side adjacent to the two recycling grooves 204, a discharge port 205 is provided. After the waste slides to the bottom of the recycling groove 204, it will fall downward through the discharge port 205. The waste falling from the discharge port 205 will directly fall into the recycling box 203, achieving effective collection of machining waste. When the waste in the recycling box 203 collects to a certain amount, the recycling box 203 can be easily slid out of the connecting frame 201 along the sliding port 202, and the waste can be conveniently and uniformly treated. The operator does not need to open the recycling box 203, but can directly observe the inside of the box through the observation window 25 to know whether the recycling box 203 needs to be cleaned in time.
[0036] Referring to Figure 1 , Figure 4 and Figure 5 , one end of each of the plurality of moving columns 16 is fixedly connected with a limiting block 21 on the left and right sides. The interior of each of the plurality of clamping plates 13 is provided with a limiting groove 22 on the left and right sides. Each of the plurality of limiting blocks 21 is slidably connected with the interior of the corresponding limiting groove 22. One side of each of the plurality of clamping side plates 17 is fixedly connected with a fixed plate 23. One side of each of the plurality of fixed plates 23 is fixedly connected with a plurality of rubber pads 24. The front lower part of the recycling box 203 is provided with a handle groove 27. The interior of the handle groove 27 is designed to be smooth. The top right side of the workbench 1 is fixedly connected with a switch 28. The switch 28 is electrically connected with the telescopic rod 10.
[0037] Specifically, the movement trajectory of the moving column 16 is limited by the cooperation of the limiting block 21 fixedly connected to one end of the moving column 16 and the limiting groove 22 opened in the inside of the clamping plate 13, which prevents the moving column 16 from deviating or shaking when it is pressed, thereby ensuring that the clamping side plate 17 applies stable and uniform clamping force to the shaft outer ring 18, ensuring the positional stability of the shaft outer ring 18 during processing. The elasticity of the rubber pad 24 prevents damage to the surface of the shaft outer ring 18 caused by rigid clamping. The rubber pad 24 increases the friction, making the clamping more stable. When the clamping side plate 17 fixes the shaft outer ring 18, it plays a role in preventing the shaft outer ring 18 from moving during processing. When it is necessary to pull out the recycling box 203 to handle waste, the operator's hand can be comfortably held in the handle slot 27, which is opened in the lower middle part of the front side of the recycling box 203 and has a smooth design inside, providing a stable point of application, making it easier for the operator to apply force, making the pulling out operation of the recycling box 203 more convenient. The operator can control the extension and retraction of the telescopic rod 10 by operating the switch 28, which is fixed to the right side of the top of the workbench 1 and electrically connected to the telescopic rod 10, thereby achieving flexible adjustment of the position of the clamping plate 13 to adapt to shaft outer rings 18 of different sizes.
[0038] Working principle: When using this bearing outer ring processing clamping device, place the shaft outer ring 18 between the space between the top of the hollow cylinder 3 and the clamping plate 13. Then turn the threaded rod 7 to make the pressing block 8 move upwards inside the hollow cylinder 3. When the pressing block 8 moves upwards, it will press the sliding block 5 in the sliding groove 4. Because the sliding block 5 can slide in the sliding groove 4, the pressing of the pressing block 8 will make the multiple sliding blocks 5 slide outward along the sliding groove 4, thereby driving the multiple arc plates 6 to open outward, preliminarily fixing the shaft outer ring 18 from the inside. At the same time, start the two telescopic rods 10, and the two clamping plates 13 approach the shaft outer ring 18. During the approach of the clamping plate 13 to the shaft outer ring 18, the clamping side plate 17 is subjected to the reaction force of the shaft outer ring 18, causing the moving column 16 to pull the spring 15 outward from the circular groove 14. The elastic deformation of the spring 15 generates an internal tensile force, and the multiple clamping side plates 17 further stably clamp the shaft outer ring 18 from the side, ensuring that the shaft outer ring 18 does not move during processing, ensuring the precision and quality of processing;
[0039] And in the bearing outer ring processing, the waste will be scattered on the workbench 1, and the top of the workbench 1 is provided with recycling groove 204, because the top of the workbench 1 is provided with recycling groove 204, the waste will gradually slide to the recycling groove 204 due to gravity and mechanical vibration in the processing, before the device works, the recycling box 203 is slid into the appropriate position, so that it is aligned with the discharge port 205, the waste falls from the recycling groove 204 to the recycling box 203 below through the discharge port 205, when the recycling box 203 is full of waste, it can be easily slid out along the sliding port 202 for waste cleaning or subsequent processing.
[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
