[0027] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0028] Embodiment 1

[0029] Refer to Figures 1-4 , which is an embodiment of the present utility model, and provides a processing die for a star-shaped sleeve. This processing die for the star-shaped sleeve includes a grinding frame 1. A rotating assembly 3 is fixedly connected to the bottom of the inner wall of the grinding frame 1 near the center. A water spraying assembly 4 is fixedly connected to the upper surface of the grinding frame 1 near the edge. A grinding assembly 2 is fixedly connected to the upper surface of the grinding frame 1 near the center;

[0030] The grinding assembly 2 includes a motor 201 fixedly connected to the grinding frame 1. The output end of the motor 201 is fixedly connected to a rotating shaft 203. Two transmission belts 202 are rotatably connected to the outer wall of the rotating shaft 203 near the center. The other end of the transmission belt 202 is rotatably connected to another rotating shaft 203. A rotating rod 204 is fixedly connected to the lower surface of the rotating shaft 203. A main gear 211 is fixedly connected to the lower surface of the rotating rod 204. Two sub-gears 213 are meshed and rotatably connected to both sides of the main gear 211. Another sub-gear 213 is provided at the front end of the main gear 211. A plurality of gear strips 212 are meshed with the outer walls of the plurality of sub-gears 213. The other end of the gear strip 212 is fixedly connected to the inner wall of the transmission belt 209. A grinding strip 210 is fixedly connected to the outer wall of the transmission belt 209. By driving the rotating rods 204 on both sides by the rotation of the motor 201, driving the main gear 211 to rotate by the rotating rod 204, and simultaneously driving the transmission belt 209 to rotate, the arc-shaped grooves on the outer wall of the star-shaped sleeve are ground by the grinding strip 210 on the outer side of the transmission belt 209. By using the relatively soft characteristic of the transmission belt 209 to fit the outer wall of the star-shaped sleeve, it can be ground better.

[0031] A support column 215 is fixedly connected below the secondary gear 213. The lower surface of the support column 215 is rotatably connected to a support plate 214. A sliding groove 216 is formed on the upper surface of the support plate 214. Another support column 215 is rotatably connected to a sliding block 217 below. The sliding block 217 slides inside the sliding groove 216. A second elastic member 218 is fixedly connected to one side of the sliding groove 216. The other end of the second elastic member 218 is fixedly connected to the sliding block 217. When the star sleeve rotates, the secondary gear 213 at the top of the drive belt 209 is pushed to move backward through the second elastic member 218. When the star sleeve rotates to the arc groove at the other end, the second elastic member 218 returns to its original position and continues to polish the arc groove on the outer wall of the star sleeve, avoiding manual replacement.

[0032] The bottom of the rotating shaft 203 is rotatably connected to a buffer chamber 205. The top of the inner wall of the buffer chamber 205 is fixedly connected to a first elastic member 206. The other end of the first elastic member 206 is fixedly connected to a connecting rod 207. The top of the connecting rod 207 is slidably connected to the buffer chamber 205. The first elastic member 206 is used to reduce the jitter of the grinding head during high-speed rotation or operation, making the grinding process more stable.

[0033] The bottom of the connecting rod 207 is fixedly connected to a protective disc 208. The bottom of the protective disc 208 is fixedly connected to a grinding disc 219 near the center. The protective disc 208 is used to prevent the grinding disc 219 from hurting the staff.

[0034] The rotating assembly 3 includes a fixed disc 301 fixedly connected to the grinding frame 1. A rotating member 302 is rotatably connected near the center of the fixed disc 301. A transmission column 303 is fixedly connected near the side of the fixed disc 301. An arc-shaped rotating disc 305 is attached to the outer wall of the rotating member 302. Transmission grooves 306 are formed at the four corners of the arc-shaped rotating disc 305. The transmission grooves 306 are adapted to the transmission column 303. By inserting the transmission column 303 into the transmission grooves 306, the arc-shaped rotating disc 305 is rotated by 90 degrees, avoiding the problem of incorrect rotation angle.

[0035] The bottom of the arc-shaped rotating disc 305 is rotatably connected to a support rod 304. The other end of the support rod 304 is fixedly connected to the bottom of the inner wall of the grinding frame 1. A connecting platform 307 is fixedly connected above the arc-shaped rotating disc 305. A limiting column 308 is fixedly connected near the center of the upper surface of the connecting platform 307. The limiting column 308 is used to limit the star sleeve.

[0036] A plurality of third elastic members 309 are fixedly connected to the outer wall of the limiting column 308. The other end of the third elastic members 309 is fixedly connected to a support plate 310. The support plate 310 is used to prevent the star sleeve from shaking.

[0037] The water spraying assembly 4 includes a water storage tank 42 fixedly connected to the grinding frame 1. One side of the water storage tank 42 is fixedly connected with a delivery pipe 43. The other end of the delivery pipe 43 is clamped to one side of a water pump 41. The other side of the water pump 41 is clamped with a water pipe 44. The other end of the water pipe 44 is fixedly connected with a spray head 45. By spraying water, the heat generated on the grinding surface can be quickly taken away, effectively reducing the temperature of the grinding surface, reducing heat accumulation, and avoiding material deformation, wear and deterioration caused by high temperature.

[0038] During the use process, the rotation of the motor 201 drives the rotating rods 204 on both sides. The rotating rods 204 drive the main gear 211 to rotate, and at the same time drive the transmission belt 209 to rotate. The grinding strips 210 on the outer side of the transmission belt 209 are used to grind the arc-shaped grooves on the outer wall of the star-shaped sleeve. Due to the relatively soft characteristics of the transmission belt 209, it can fit the outer wall of the star-shaped sleeve for better grinding. At the same time, the transmission column 303 extends into the transmission groove 306, causing the arc-shaped rotating disk 305 to rotate 90 degrees, so that the star-shaped sleeve pushes the transmission belt 209, and the sub-gear 213 at the top of the transmission belt 209 moves backward through the second elastic member 218. When the star-shaped sleeve rotates to the arc-shaped groove at the other end, the second elastic member 218 returns to its original position and continues to grind the arc-shaped groove on the outer wall of the star-shaped sleeve. The top uses the first elastic member 206 to reduce the jitter of the grinding head during high-speed rotation or operation.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
