[0026] As shown in Figures 1-3As shown, the reciprocating grinding assembly 7 includes a boss 701, a drive pin 702, a guide rod 703, a connecting plate 704, and a drive rod 705. The drive rod 705 passes through the boss 701 and is fixedly connected to the boss 701. The drive pin 702 is fixedly connected to the outside of the guide rod 703. A drive groove 11 is provided on the outside of the boss 701, and the drive pin 702 is movably engaged with the drive groove 11. Both ends of the guide rod 703 are fixedly connected to the connecting plate 704. The boss 701 is movably connected to the support frame 3 through the drive rod 705, and the guide strips 6 are rotatably connected to the inner side of the connecting plate 704. The guide rod 703 passes through the support frame 3 and is movably connected to the support frame 3. Both ends of the top of the support frame 3 are movably connected to the sleeve. The sleeve 12 and guide strip 6 pass through the sleeve 12 respectively, and the guide strip 6 is movably connected to the sleeve 12. The outer side of the support frame 3 is fixedly connected to the servo motor 13, and the output end of the servo motor 13 is fixedly connected to one end of the drive rod 705. The reciprocating grinding assembly 7 also includes a first synchronous pulley 706, a second synchronous pulley 707 and a synchronous belt 708. The first synchronous pulley 706, the second synchronous pulley 707 and the synchronous belt 708 are all symmetrically arranged. The first synchronous pulley 706 is fixedly connected to the outer side of the sleeve 12, the second synchronous pulley 707 is fixedly connected to the outer side of the drive rod 705, and the synchronous belt 708 is sleeved on the outer side of the first synchronous pulley 706 and the second synchronous pulley 707. The first synchronous pulley 706, the second synchronous pulley 707 and the synchronous belt 708 constitute a belt drive structure.
[0027] The servo motor 13 is started, driving the drive rod 705 to rotate, causing the boss 701 to rotate synchronously. Due to the movable engagement between the drive pin 702 and the drive groove 11, the support frame 3 restricts the movement direction of the guide rod 703, thereby causing the guide rod 703 to reciprocate. Under the action of the connecting plate 704, the grinding wheel 5 is driven to reciprocate synchronously. The drive rod 705 rotates, simultaneously driving the synchronous wheel 707 to rotate. Under the action of the synchronous belt 708, the sleeve 12 rotates synchronously, thereby causing the guide bar 6 and the grinding wheel 5 to rotate synchronously. This allows the grinding wheel 5 to swing back and forth during rotation, improving the grinding effect on the workpiece 4. Furthermore, grinding wheels 5 are provided on both sides of the workpiece 4, further improving the grinding efficiency of the workpiece 4.
[0028] like Figure 1 and Figure 4As shown, the centering component 10 includes a clamping block 1001, a moving block 1002, a connecting rod 1003, and a connecting block 1004. The clamping block 1001, the moving block 1002, and the connecting rod 1003 are symmetrically arranged. The clamping block 1001 is fixedly connected to the end of the moving block 1002. One end of the connecting rod 1003 is movably connected to the outside of the moving block 1002 through a rotating shaft, and the other end of the connecting rod 1003 is movably connected to both sides of the connecting block 1004 through a rotating shaft. Hydraulic rods 14 are fixedly connected to the inner side of the support plate 8, and the telescopic end of the hydraulic rod 14 is fixedly connected to the connecting block 1004. A set of symmetrical sliding grooves 15 are opened on the inner side of the support plate 8, and the moving blocks 1002 are slidably connected to the inside of the sliding grooves 15. A servo motor 2 16 is fixedly connected to the outside of one of the support plates 8, and the output end of the servo motor 2 16 is fixedly connected to the rotating shaft of the turntable 9.
[0029] The workpiece 4 is placed on the opposite side of the turntable 9. Then, the connecting block 1004 is moved downward by the hydraulic rod 14. Under the action of the connecting rod 1003, the moving block 1002 is pulled closer to each other along the slide groove 15 until the clamping block 1001 performs the centering operation on the workpiece 4. Then, the two turntables 9 are controlled by the slide rail 2 to clamp the end of the workpiece 4. Then, the clamping block 1001 is released from clamping the workpiece 4. This makes the axis of the workpiece 4 quickly aligned with the axis of the turntable 9, which helps to improve the grinding stability of the workpiece 4 and avoids the workpiece 4 from shifting position during the grinding process, thereby ensuring the grinding quality of the workpiece 4.
[0030] Working principle: In use, firstly, the linear movement of the support frame 3 is controlled by slide rail 1, and the linear movement of each support plate 8 is controlled by slide rail 2. During use, the workpiece 4 is placed on the opposite side of the turntable 9. Then, the connecting block 1004 is moved downwards by the hydraulic rod 14. Under the action of the connecting rod 1003, the moving block 1002 is pulled closer to each other along the slide groove 15 until the clamping block 1001 centers the workpiece 4. Next, the two turntables 9 are clamped at the end of the workpiece 4 by slide rail 2. Then, the clamping block 1001 is released from the workpiece 4, and the turntable 9 is rotated by servo motor 2 16, thus controlling the rotation of the workpiece 4. Finally, servo motor 13 is started to drive... The drive rod 705 rotates, causing the boss 701 to rotate synchronously. Due to the movable engagement between the drive pin 702 and the drive groove 11, the support frame 3 restricts the movement direction of the guide rod 703, thereby causing the guide rod 703 to reciprocate. Under the action of the connecting plate 704, the grinding wheel 5 reciprocates synchronously. The drive rod 705 rotates, simultaneously driving the synchronous wheel 707 to rotate. Under the action of the synchronous belt 708, the sleeve 12 rotates synchronously, thereby causing the guide bar 6 and the grinding wheel 5 to rotate synchronously. The rotation direction of the two grinding wheels 5 and the workpiece 4 is controlled to be the same, thereby performing high-speed grinding on the surface of the workpiece 4. The movement direction of the support frame 3 is controlled by the slide rail 1, thereby grinding different positions of the workpiece 4.

Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
