[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a ball cage retainer end face fine milling device, including a cabinet 1, a collecting tank 3 is opened on the top of the cabinet 1, a fixing frame 4 is fixedly connected inside the collecting tank 3, a first motor 5 is fixedly connected inside the fixing frame 4, a rotating rod 6 is fixedly connected to the output end of the first motor 5, both ends of the rotating rod 6 are rotatably connected to connecting rods 7, one end of the two connecting rods 7 are rotatably connected to sliders 9, the proximal ends of the two sliders 9 are rotatably connected to rotating shafts 10, the proximal ends of the two rotating shafts 10 are fixedly connected to clamps 11, the other end of the right rotating shaft 10 is fixedly connected to a worm gear 15, the outer side of the worm gear 15 is meshingly connected to a worm 16, a flushing assembly is installed inside the cabinet 1, and the rear end of the cabinet 1 is fixedly connected to a fine milling assembly.

[0025] Specifically, the fixing frame 4 is fixed inside the collecting tank 3 through the cabinet 1, and then the first motor 5 is fixed through the fixing frame 4, so that the device is stable and not easy to shake during operation, and then the rotating rod 6 is driven to rotate by the first motor 5, so that the connecting rod 7 connected at both ends of the rotating rod 6 moves, and then the slider 9 is driven to slide inside the slide groove 8 respectively, so that the clamping operation of the ball cage retainer is realized through the two clamping plates 11, so that it will not be offset during fine milling, resulting in deviations in machining accuracy and affecting the final machining effect. Then the worm 16 can be rotated, and the worm wheel 15 is driven by the worm 16 to rotate, and then the rotating shaft 10 is rotated, so that the clamped ball cage retainer is turned over, so that the worker can change the machining surface without removing it, thereby improving the machining efficiency.

[0026] Reference Figure 4 The flushing component includes a water tank 19, which is fixedly connected to the inside of the cabinet 1, and the outside of the water tank 19 is fixedly connected to a filter box 20, and the outside of the filter box 20 is fixedly connected to a water pump 21, and the output end of the water pump 21 is fixedly connected to a water pipe 22; the other end of the water pipe 22 is fixedly connected to the top of the support frame 2, and the other end of the water pipe 22 is fixedly connected to a high-pressure nozzle.

[0027] Specifically, through the operation of the water pump 21, the water in the water tank 19 enters the filter box 20, and then the impurities therein are filtered out and transported to the fine milling drill bit 14 through the water pipe 22 to flush the processed ball cage retainer, so that the cutting debris is washed away in time, keeping the cutting area clean, and improving the processing efficiency and accuracy. The flushing water flow enters the collecting tank 3, passes through the filter plate 17 to filter out the debris, and then enters the water tank 19 through the connecting pipe 18, thereby fully utilizing the water and saving water resources.

[0028] Reference Figure 1 The fine milling assembly includes a support frame 2, which is fixedly connected to the top rear end of the cabinet 1, and a cylinder 12 is fixedly connected to the top of the support frame 2. The output end of the cylinder 12 is fixedly connected to a second motor 13, and the output end of the second motor 13 is fixedly connected to a fine milling drill bit 14.

[0029] Specifically, the support frame 2 is fixed at the top rear end of the cabinet 1. The support frame 2 fixes the cylinder 12, so that the cylinder 12 is always in a straight line when pushing the second motor 13 to move. At the same time, the second motor 13 drives the fine milling drill 14 to process the ball cage retainer stably without shaking, ensuring the processing accuracy without error, thereby ensuring the processing effect.

[0030] Reference Figure 1 , Figure 2 and Figure 4A placement rack 23 is fixedly connected to the top of the cabinet 1, and a plurality of supporting feet are arranged at the bottom of the cabinet 1; a filter plate 17 is fixedly connected to the inside of the collecting tank 3, and a connecting pipe 18 is fixedly connected to the bottom of the collecting tank 3, and one end of the connecting pipe 18 is fixedly connected to the outside of the water tank 19; slide grooves 8 are provided on both sides of the top of the cabinet 1, and the inner wall of the slide groove 8 is slidably connected to the outside of the slider 9; the two ends of the worm 16 are respectively rotatably connected to the inside of the slider 9, and one end of the worm 16 is fixedly connected to a turning handle.

[0031] Specifically, by fixing the placement frame 23 on the top of the cabinet 1, the ball cage retainer to be processed is supported, which is convenient for clamping by the clamping assembly. Multiple supporting feet make the placement of the cabinet 1 more stable, thereby ensuring the processing effect. The debris flushed during processing is collected through the collection trough 3 for easy processing. At the same time, the debris in the water is filtered out by the filter plate 17, and then enters the water tank 19 through the connecting pipe 18. Finally, the water is fully utilized through the flushing assembly, thereby improving the water utilization rate and saving water resources. The slide groove 8 restricts the bottom of the slider 9 so that the two sliders 9 remain in a straight line when moving, thereby ensuring the clamping effect. The worm gear 15 can be driven to rotate by rotating the worm 16, and then the processing surface of the processed ball cage retainer can be adjusted, so that the surface can be changed and fine milling can be achieved without removing it, thereby improving work efficiency.

[0032] Working principle: When fine milling the ball cage retainer, first place the retainer on the placement rack 23, then start the first motor 5, and drive the rotating rod 6 to rotate through the first motor 5, so that the connecting rod 7 connected at both ends moves, and then drives the two sliders 9 to slide along the slide groove 8 respectively. After approaching each other, the retainer is clamped by the clamping plate 11 to achieve the fixation of the retainer to prevent it from moving during fine milling, thereby causing deviation in fine milling and affecting the final use. Then, the worm 16 is rotated by the turning handle, and then the worm wheel 15 is driven to rotate, so that the clamped ball cage retainer rotates, so that it does not need to be removed, and the fine milling surface can be changed, which is convenient for workers to process and improves work efficiency. Start the cylinder 12, so that the cylinder 12 pushes the second motor 13 close to the ball cage retainer on the placement rack 23, and the fine milling drill 14 at the output end of the second motor 13 is used for processing, thereby achieving fine milling operation, reducing friction during use, and ensuring stable operation. While fine milling is being performed, the water pump 21 is started. At this time, the water in the water tank 19 is filtered by the filter box 20 under the action of the water pump 21, enters the water pipe 22 from the output end of the water pump 21, and is finally sprayed out from the nozzle at the other end to flush the ball cage retainer being fine milled to flush away the debris, and at the same time cool the fine milling drill bit 14, thereby improving the processing quality and extending the service life of the drill bit.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
