[0026] Embodiment two, please refer to Figures 1-14The second embodiment is improved on the basis of the first embodiment.

A cover plate 302 is fixedly connected to the top of the cylindrical pipe 301. A second positioning slot 303 is formed in the top of the cover plate 302. Two second L-shaped plates 304 are symmetrically and slidably connected in the cylindrical pipe 301 and slide through the cover plate 302. Arc-shaped clamping plates 305 are fixedly connected to the ends of the second L-shaped plates 304. First guide slots 306 are symmetrically formed in the bottom of the cylindrical pipe 301 and slidably match the two second L-shaped plates 304. Second guide slots 307 are symmetrically and throughly formed in the bottom of the second positioning slot 303 and slidably match the two second L-shaped plates 304. First sleeve pipes 308 are symmetrically and fixedly connected to the bottom of the cylindrical pipe 301. Trigger rods 309 are slidably connected in the first sleeve pipes 308 and slide through the cover plate 302. First springs 310 are fixedly connected between the trigger rods 309 and the first sleeve pipes 308. Straining rods 311 are hingedly connected between adjacent trigger rods 309 and second L-shaped plates 304. Insert rods 312 are slidably inserted on the outer walls of the trigger rods 309. Grooves are formed in the outer walls of the trigger rods 309. Second springs are fixedly connected between the insert rods 312 and the grooves. Clamping holes 313 are symmetrically and throughly formed in the outer walls of the cylindrical pipe 301 and match the two insert rods 312. First U-shaped plates 314 are symmetrically and fixedly connected to the outer walls of the cylindrical pipe 301. Jack rods 315 are slidably connected to one outer side of the first U-shaped plates 314 and match the clamping holes 313. Baffles 316 are fixedly connected to one end of the jack rods 315. Third springs 317 are fixedly connected between the baffles 316 and the first U-shaped plates 314.

[0027] The operation process of the embodiment is as follows. First, the shaft sleeve is accurately inserted into the second positioning slot 303 on the cover plate 302 to ensure that the initial positioning is accurate. Then, pressure is applied downward on the shaft sleeve to stably move it downward, thereby extruding the trigger rod 309 below, driving the trigger rod 309 to move downward along the axial direction, and the downward movement of the trigger rod 309 further drives the connected insert rod 312 to move downward synchronously until the end of the insert rod 312 is accurately aligned with the position of the clamping hole 313. At this time, under the elastic force of the second spring, the insert rod 312 is quickly pushed into the clamping hole 313 to complete the locking operation of the trigger rod 309 (in this process, the first spring 310 stores elastic energy due to compression). At the same time, the downward movement of the trigger rod 309 swings the straining rod 311 through linkage, prompting the straining rod 311 to drive the second L-shaped plate 304 to move close to the inner wall of the shaft sleeve, thereby driving the arc-shaped clamping plate 305 to move synchronously to the inner wall of the shaft sleeve, achieving quick and firm fixation of the shaft sleeve. This clamping mechanism ensures that the shaft sleeve remains stable during subsequent grinding processing, effectively avoiding vibration or displacement, thereby ensuring high-quality completion of the grinding process. Next, by pressing the baffle 316 at the same time, the driving top rod 315 moves to the inside of the card hole 313, and the end of the top rod 315 is in contact with the plug rod 312, forcing the plug rod 312 to retreat away from the card hole 313, thereby releasing the locking state of the plug rod 312 and the card hole 313, and at the same time, under the elastic recovery action of the first spring 310, the trigger rod 309 is pushed back to the original position, and the upward movement of the trigger rod 309 drives the second L-shaped plate 304 and the arc-shaped clamping plate 305 to move away from the inner wall of the shaft sleeve through the supporting rod 311, quickly releasing the clamping force on the shaft sleeve, and at the same time, the trigger rod 309 lifts the shaft sleeve upward during the upward movement, thereby achieving rapid disassembly of the shaft sleeve, making the replacement operation of the shaft sleeve extremely simple and efficient, and significantly improving the convenience of maintenance and adjustment; The device is designed ingeniously and can accommodate and process four groups of shaft sleeves at the same time. Among them, three groups of shaft sleeves can be ground synchronously, and the other group of shaft sleeves is in a non-processing state and is reserved for replacement. By driving the rotating assembly 2 to rotate 90° by the first motor 102, when the three groups of shaft sleeves are processed, the rotating assembly rotates them to the non-processing station, which is convenient for the operator to disassemble and replace them. This layout ensures that the shaft sleeves on the three stations can be ground synchronously, and the fourth station is always in a replaceable state, thereby realizing the cooperation of processing and replacement. This design not only significantly improves the consistency and processing quality of shaft sleeve grinding, but also greatly improves the overall production efficiency, ensuring the continuity and efficiency of the production process.

[0031] The operation process of the embodiment is as follows: the sun gear 208 starts to rotate under the driving of the power, the rotation is transmitted to the worm 402 through the second sleeve 401 in close engagement with the sun gear 208, the worm 402 can not only move axially up and down inside the second sleeve 401, but also rotate synchronously with the second sleeve 401 due to the sliding fit structure formed between the second clamping rod 404 on the worm 402 and the second sliding groove 403 on the inner wall of the second sleeve 401, the rotation of the worm 402 further drives the worm wheel 509 in engagement therewith to rotate, the worm wheel 509 drives the second bevel gear 508 through the second rotating rod 507, the second bevel gear 508 meshes with the first bevel gear 505 to transmit power to the first bevel gear 505, and then drives the cleaning roller 504 to rotate through the first rotating rod 503, the cleaning roller 504 cleans the outer wall of the shaft sleeve during rotation, effectively removes the debris generated during polishing, prevents the debris from adhering to the outer wall of the shaft sleeve during grinding to cause secondary scratches, and thus guarantees the smoothness and overall quality of the outer wall of the shaft sleeve; At the same time, one of the cylindrical pipes 301 drives the annular guide plate 605 to rotate synchronously during rotation, and the rotating motion of the annular guide plate 605 periodically presses against the abutting rod 603. Under the elastic force of the first return spring 405, the abutting rod 603 moves up and down along the contour direction of the annular guide plate 605, the abutting rod 603 pushes the abutting plate 406 through the annular sleeve 604, and under the elastic restoring force of the first return spring 405, the abutting rod 603 drives the worm 402 to move up and down axially, which further transmits to the cleaning assembly 5 connected to the worm 402, so that the cleaning assembly 5 moves up and down as a whole, thereby expanding the cleaning coverage of the cleaning roller 504 and enhancing the cleaning effect, ensuring that the cleaning of the outer wall of the shaft sleeve is more comprehensive and thorough.

[0033] The operation process of the embodiment is as follows: by controlling the rotating motion of the first sprocket 108, the second sprocket 706 is effectively driven to rotate synchronously through the high-strength transmission chain, so that one of the driving transmission rods 703 starts to rotate, and the belt pulley 705 at the top of the transmission rod 703 starts to operate, and the other two groups of transmission rods 703 are simultaneously driven to rotate synchronously through the belt, and the synchronous rotation of the three transmission rods 703 further drives the three groups of grinding rollers 704 mounted on the rods to move in concentric circles. In this process, by controlling the extension and retraction motion of the hydraulic cylinder 114, the entire grinding assembly 7 moves smoothly from top to bottom along the vertical direction, and at the same time, the rotation of the shaft sleeve is matched, and finally the outer surface of the shaft sleeve is fully, uniformly and high-precision ground.
