[0028] As a technical optimization of this utility model, the moving mechanism includes a sliding plate 6, which can move along the length of the frame 1. Multiple support arms 4 are mounted on the top of the sliding plate 6, one more than the number in the grinding mechanism. Clamping components are mounted on the bottom of the end of each support arm 4 furthest from the sliding plate 6. A sliding rod 24 is mounted on the top of the frame 1 below the sliding plate 6 along the length. Multiple telescopic cylinders 25 are mounted on the top of the frame 1 below the sliding rod 24. The telescopic cylinders 25 can drive the sliding rod 24 to move vertically. A horizontal motor 21 is installed on one side wall of the slide rod 24. The output end of the horizontal motor 21 is connected to a lead screw 22. A connecting block 23 is fitted on the external thread of the lead screw 22. One side of the connecting block 23 is slidably installed with the slide rod 24 via a slider. The top of the connecting block 23 is connected to the bottom of the sliding plate 6. Multiple guide blocks 28 are sequentially connected to one side of the slide rod 24. Multiple vertical rods 27 are installed on the top of the frame 1 on the side of the slide rod 24. A guide rail 29 is vertically installed on one side of the vertical rod 27. The guide blocks 28 are slidably installed with the guide rail 29.

[0029] As a technical optimization of this utility model, the clamping assembly on the support arm 4 near the synchronous belt 3 is mounted on the side plate 9, and the clamping assemblies on the other support arms 4 are all mounted on the bottom of the movable seat 17. The clamping assembly includes two grippers 10, and one side of the gripper 10 is connected to an electric slide plate 11. The bottom of the movable seat 17 and the side wall of the side plate 9 are provided with sliding grooves for the electric slide plate 11 to slide. The grippers 10 can clamp and move the workpiece as the electric slide plate 11 moves.

[0030] As a technical optimization of this utility model, a second mounting bracket 8 is installed on the top of the frame 1 between the sliding plate 6 and the first mounting bracket 7. Multiple pressing cylinders 5 are sequentially installed on the top of the second mounting bracket 8. The telescopic ends of the pressing cylinders 5 extend downwards through the second mounting bracket 8. A guide rod 18 is connected to the top of the movable seat 17, and the telescopic ends of the pressing cylinders 5 can abut against the top of the guide rod 18. The downward extension of the telescopic ends of the pressing cylinders 5 presses down on the guide rod 18, making the workpiece more stable during the grinding process.

[0031] As a technical optimization of this utility model, a vertically extendable electric telescopic rod 15 is installed on the top of the frame 1 below each grinding mechanism and the sliding plate 6. A support base 16 is connected to the top of the electric telescopic rod 15, and a clamping assembly is also installed on the top of the support base 16. A sliding groove is provided on the top of the support base 16, and the gripper 10 is slidably mounted on the top of the support base 16 via an electric sliding plate 11 and the sliding groove. The support base 16 is located directly below the corresponding clamping cylinder 5. The electric telescopic rod 15 can drive the support base 16 to move up and down. During the grinding process, the workpiece can be moved vertically as needed, allowing the outer wall of the workpiece to be fully ground.

[0032] In use, this invention features three grinding mechanisms mounted on the top of the frame 1, each equipped with a different type of grinding belt. From one end near the synchronous belt 3 to the other, these belts are for preliminary rough grinding, fine grinding, and final polishing. Several workpieces are placed sequentially on the synchronous belt 3, which moves towards one end of the frame 1. When a workpiece at the end of the synchronous belt 3 reaches a preset pick-up position, the synchronous belt 3 stops. The telescopic cylinder 25 drives the slide bar 24 downwards, causing the moving mechanism at the pick-up point above the synchronous belt 3 to move downwards. Two grippers 10 on the moving mechanism insert into two holes at the end of the workpiece. Then, the electric slide plate 11 drives the grippers 10 to clamp the workpiece. Next, the telescopic cylinder 25 drives the moving mechanism upwards to a preset height. The horizontal motor 21 drives the lead screw 22 to rotate forward, and the connecting block 23 moves on the lead screw 22 and slide bar 24, causing the sliding plate 6 to move away from the synchronous belt 3. Until the workpiece to be processed moves to the roughing station, the moving mechanism moves downwards, placing the workpiece on the support seat 16 of the grinding station. Then, the sliding plate 6 moves upwards and towards one end of the synchronous belt 3, returning to its original position, and then moves downwards again. At this time, the moving seat 17 on the grinding station presses down on the top of the workpiece, and the moving mechanism near the synchronous belt 3 clamps the workpiece at the pick-up position on the synchronous belt 3 again. After the workpiece at one station is ground, the combined use of the moving clamping structure and the sliding plate 6 allows the workpiece to move vertically and horizontally, placing it sequentially at subsequent grinding stations. After rough grinding, fine grinding, and polishing, the workpiece is finally moved by the clamping mechanism to the end of the frame 1 furthest from the synchronous belt 3 and falls into the pre-prepared receiving box for collection.

[0033] After the workpiece is placed in the grinding station, the grippers 10 on the movable seat 17 and the support seat 16 can clamp and limit the workpiece. Furthermore, the telescopic end of the upper pressing cylinder 5 extends downwards to press the guide rod 18, making the workpiece more stable during grinding. Since the movable seat 17 and the support seat 16 are rotatably mounted to the support arm 4 and the electric telescopic rod 15 respectively, and a rotating motor is installed between the top of the movable seat 17 and the support arm 4, the movable seat 17 can drive the workpiece to rotate during grinding, allowing the outer wall of the workpiece to be thoroughly ground.

[0034] During grinding, the drive motor 12 rotates the mounting plate 19, causing the grinding belt on the outer wall of the grinding wheel 14 to contact the outer wall of the workpiece. Then, the grinding motor drives the drive wheel 20 to rotate, causing the grinding belt to rotate and grind the outer wall of the workpiece. As the workpiece rotates during grinding, and since the outer wall of the workpiece is not circular, the drive motor 12 rotates along with the mounting plate 19, ensuring stable grinding of the workpiece by the grinding belt.
