[0015] 1. This utility model utilizes a first motor to drive a rotating rod, which in turn drives a horizontal plate and a grinding mechanism connected below the horizontal plate to rotate, achieving dual-station switching. Once the workpiece on one station has been ground, the first motor is activated, and the rotating rod rotates 180°, moving the grinding mechanism to the other station. At this point, unloading and loading operations can be performed at the station where grinding has been completed, while the grinding mechanism can immediately begin grinding the workpiece on the other station, significantly reducing the time wasted on changing materials and improving production efficiency.

[0016] 2. In this utility model, through the first transmission mechanism, the third motor drives the first lead screw to rotate, so that the first crossbar can move back and forth along the first lead screw, thereby adjusting the position of the grinding roller in the horizontal direction to meet the grinding needs of different workpieces; in the second transmission mechanism, the hydraulic cylinder works, and its piston rod extends and retracts to drive the second crossbar to move up and down, thereby adjusting the height of the grinding roller, realizing the grinding of different thickness parts of the workpiece, and improving the flexibility and accuracy of grinding.

[0017] 3. In this utility model, through the third transmission mechanism, when the rotating rod rotates, it drives the first bevel gear fixedly sleeved at its lower end to rotate. The first bevel gear meshes with two second bevel gears, causing the internal threaded tube to rotate. The second lead screw inside the internal threaded tube drives the slide plate to slide in the placement shell under the action of the thread, realizing automatic clamping and loosening of the workpiece. Moreover, by adjusting the rotation of the threaded rod in the adjustment mechanism, the distance between the clamping plate and the slide plate can be finely adjusted to adapt to workpieces of different sizes, thus improving the versatility of the grinding machine.

[0027] Reference Figure 1-3 A first transmission mechanism is provided on the lower side of the horizontal plate 10 to drive the first horizontal bar 11 to move back and forth. The first transmission mechanism includes a first lead screw 16 and a second side plate. The two second side plates are fixedly set on both sides of the lower surface of the horizontal plate 10. The first lead screw 16 is rotatably set between one end of the two second side plates. One end of the first horizontal bar 11 is threadedly connected to the first lead screw 16. A third motor 15 is fixedly set on the outer side of one of the second side plates. The output end of the third motor 15 is fixedly connected to one end of the first lead screw 16. A limit rod 17 is set parallel to one side of the first lead screw 16. The two ends of the limit rod 17 are fixedly connected to the corresponding second side plates respectively. One end of the first horizontal bar 11 is movably sleeved with the limit rod 17, so that the first horizontal bar 11 can move stably along the first lead screw 16.

[0028] Reference Figure 1-3 A second transmission mechanism is provided on the lower side of the first crossbar 11 to drive the second crossbar 12 to move longitudinally. The second transmission mechanism includes a hydraulic cylinder 13, which is fixedly installed in the middle of the lower surface of the first crossbar 11. The piston rod end of the hydraulic cylinder 13 is fixedly connected to the second crossbar 12. Fixed tubes 20 are fixedly installed at both ends of the upper surface of the second crossbar 12. A movable rod 21 is movably sleeved inside the fixed tube 20. The upper end of the movable rod 21 is fixedly connected to the first crossbar 11.

[0029] Reference Figure 1-3The lower end of the rotating rod 9 is provided with a third transmission mechanism that drives the sliding plates 4 on both sides to move. The third transmission mechanism includes a first bevel gear 24 and a second bevel gear 25. The side of the housing 2 near the rotating rod 9 is provided with an internally threaded tube 7. The internal threads of the internally threaded tube 7 are connected to a second lead screw 8. One end of the second lead screw 8 extends to the inner side of the housing 2 and is fixedly connected to the sliding plate 4. The first bevel gear 24 is fixedly sleeved on the lower end of the rotating rod 9. The two second bevel gears 25 are fixedly sleeved on the outer wall of the corresponding internally threaded tube 7. The two second bevel gears 25 are respectively meshed with the two sides of the first bevel gear 24.

[0030] Reference Figure 1-3 An adjustment mechanism is provided between the clamping plate 3 and the slide plate 4 to adjust the distance between them. The adjustment mechanism includes a threaded rod 5. One end of the slide plate 4 has a threaded hole, and the threaded rod 5 is threaded into the inside of the threaded hole. One end of the threaded rod 5 is fixedly connected to the clamping plate 3. The slide plate 4 has a through hole at the end away from the threaded hole. A slide rod 6 is slidably arranged inside the through hole. One end of the slide rod 6 is fixedly connected to the clamping plate 3, so that the clamping plate 3 can move stably. The longitudinal sections of the slide plate 4 and the housing 2 are both rectangular, so that the slide plate 4 cannot rotate, that is, it can slide stably.

[0031] In this invention, during use, firstly, according to the size of the workpiece, the distance between the clamping plate 3 and the sliding plate 4 is adjusted by the adjusting mechanism. The threaded rod 5 rotates within the threaded hole of the sliding plate 4, causing the clamping plate 3 to move closer to or away from the sliding plate 4. Simultaneously, the sliding rod 6 slides within the through hole of the sliding plate 4, ensuring the stability of the clamping plate 3's movement. The workpiece is placed between the sliding plate 4 and the clamping plate 3 on one side of the workstation. Automatic clamping is achieved through the third transmission mechanism. The first motor 23 is started, driving the rotating rod 9 to rotate. The first bevel gear 24 at the lower end of the rotating rod 9 rotates accordingly. The first bevel gear 24 meshes with the second bevel gear 25, causing the internal threaded tube 7 to rotate. The second lead screw 8, under the action of the thread, pushes the sliding plate 4 to slide within the placement shell 2, thereby clamping the workpiece. Then, the second motor 19 is started, driving the grinding roller 14 to rotate. The grinding roller 14 is adjusted through the first transmission mechanism. At the horizontal position of position 4, the third motor 15 is started, which drives the first lead screw 16 to rotate. The first crossbar 11 moves back and forth on the first lead screw 16. The limiting rod 17 ensures the stability of the movement of the first crossbar 11. Then, the height of the grinding roller 14 is adjusted through the second transmission mechanism. The hydraulic cylinder 13 is started, and the piston rod of the hydraulic cylinder 13 extends and retracts, driving the second crossbar 12 to move up and down. The fixed tube 20 and the movable rod 21 play a guiding role to ensure that the second crossbar 12 moves smoothly. After the position of the grinding roller 14 is adjusted, the workpiece is ground. When the workpiece on this side is ground, the first motor 23 is started, and the rotating rod 9 rotates 180° to rotate the grinding mechanism to the other side. At this time, unloading and loading operations can be performed at the workpiece that has been ground, and the grinding mechanism can immediately grind the workpiece on the other side. This cycle is repeated to achieve efficient and continuous grinding work.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
