[0029] 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.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a grinding device for gear processing, including a box body 1, which is the main body of the entire device and provides support and protection. A switch door 11 is provided on the front of the box body 1, and the switch door 11 is located on the front of the box body 1, which is convenient for loading and removing gears and ensuring safety during the grinding process. Four groups of symmetrically arranged support legs 12 are fixedly connected to the bottom surface of the box body 1, and the support legs 12 are used to provide stable support and balance for the device. The inner walls on both sides of the box body 1 are respectively fixedly connected with a cylinder 2 and a motor 3, and the output end of the cylinder 2 is rotatably connected with a pressure plate 21, and the output end of the motor 3 is fixedly connected with a turntable 31. The output end of the cylinder 2 is used to drive the pressure plate 21 to press the gear against the side wall of the turntable 31, and the turntable 31 is driven to rotate by the output end of the motor 3, so that the gear and the pressure plate 21 rotate synchronously.

[0031] Reference Figure 2-Figure 4The surface of the cylinder 2 and the bottom surface of the motor 3 are both provided with a grinding assembly 4. The grinding assembly 4 is provided with two groups, which are respectively located on the surface of the cylinder 2 and the bottom surface of the motor 3, and are responsible for grinding the outer wall, surface and bottom surface of the gear to improve the efficiency of gear processing. The grinding assembly 4 includes an elastic telescopic rod 41, which is fixedly connected to the bottom surface of the motor 3. The bottom end of the elastic telescopic rod 41 is fixedly connected with a horizontal plate 42. The elastic telescopic rod 41 is used to drive the horizontal plate 42 to fit tightly with the outer wall of the gear. The surface of the horizontal plate 42 is provided with a slide groove 43, and the interior of the slide groove 43 is slidably connected with a vertical plate 44. The slide groove 43 is used to provide a moving track for the vertical plate 44. The vertical plate 44 is used to fit with the surface of the gear. The inner wall of the slide groove 43 is fixedly connected with a guide rod 45, which passes through and is slidably connected to the side wall of the vertical plate 44. The guide rod 45 is used to position and guide the vertical plate 44, so that the vertical plate 44 is more stable during movement. The vertical plate 44 is elastically connected to the inner wall of the slide groove 43 through a return spring 46, and the return spring 46 is sleeved on the outer wall of the guide rod 45. The return spring 46 is used to elastically support the vertical plate 44, so that the vertical plate 44 and the surface of the gear are tightly fitted together. The side wall of the vertical plate 44 and the surface of the cross plate 42 are provided with a frosted surface 47. When the gear rotates, it fits with the frosted surfaces 47 of the vertical plate 44 and the cross plate 42, thereby achieving comprehensive grinding of the gear and improving processing efficiency.

[0032] Reference Figure 2 An inclined plate 5 is fixedly connected between the inner walls of the box body 1, and a chip discharge port 6 is opened on the side wall of the box body 1. The end of the inclined plate 5 corresponds to the position of the chip discharge port 6. The inclined plate 5 is used to guide the generated debris to slide off the gear and enter the chip discharge port 6, and discharge the generated debris through the chip discharge port 6 to keep the device clean.

[0033] Working principle: When in use, first put the gear to be processed into the box body 1 through the switch door 11, and then start the cylinder 2 and the motor 3. The output end of the cylinder 2 drives the pressure plate 21 to press the gear against the side wall of the turntable 31 to ensure that the gear will not move or slip during the grinding process. Subsequently, the output end of the motor 3 starts to drive the turntable 31 to rotate, so that the gear and the pressure plate 21 rotate synchronously. Due to the setting of the grinding component 4, the outer wall, surface and bottom surface of the gear will be effectively polished during the rotation process. The elastic telescopic rod 41 of the grinding component 4 can ensure that the horizontal plate 42 always keeps a close fit with the outer wall of the gear, and the vertical plate 44 in the slide 43 is supported by the elastic force of the return spring 46 and fits closely with the surface of the gear. In this way, when the gear rotates, its surface will produce friction with the frosted surface 47 of the horizontal plate 42 and the vertical plate 44, thereby achieving the grinding effect. During the grinding process, the generated debris will slide along the inclined plate 5 and finally be discharged from the box body 1 through the chip discharge port 6 to keep the inside of the device clean.

[0034] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
