[0014] The operation method of the crystal rod processing device is as follows: S1: The user places the crystal rod on the clamping plate on the lower rotating motor. The two clamping plates of the device are located between the horizontal plate and the bottom of the support frame. The first cylinder and the second cylinder are operated by the device system to move. The second cylinder drives the grinding shell on the support frame to move. The crystal rod is assisted in positioning by the movable clamping end of the first cylinder and the grinding shell. Then the lifting cylinder drives the upper rotating motor to move downward, so that the clamping plate on the upper rotating motor can press and fix the crystal rod. Then the first cylinder is reset, and the grinding shell is pressed tightly on the crystal rod. S2: Then the lower rotating motor and the upper rotating motor jointly drive the clamped crystal rod to rotate, and at the same time the driving motor drives the screw to rotate counterclockwise. At this time, the screw will drive the corresponding grinding shell to rotate synchronously through the moving table, the connecting arm and the regulating frame. The three grinding shells together constitute a complete rigid grinding cylinder to quickly and roughly grind the surface of the crystal rod.

At this time, the limit block on the rotating table is just aligned with the lower guide groove, and the transmission block enters the arc groove at the bottom of the docking piece; S4: Since the one-way teeth are locked, the rotating table will not be able to rotate at this time. The screw can drive the two moving tables to approach each other through the thread groove.

The grinding shell drives the winding rod and the transmission block to move synchronously through the outer cylinder. During this process, the limit block at the bottom of the grinding shell will enter the lower guide groove, and the transmission block will drive the docking piece and the guide table to slide along the upper guide groove. The servo motor on the guide table drives the docking piece to rotate under the control of the system program, and the docking piece will drive the transmission block and the winding rod to rotate, and the fine grinding belt on the winding rod will be unfolded. At this time, the fine grinding belts between adjacent grinding shells will be pulled apart, and then the second cylinder will be started again, so that the middle part of the unfolded fine grinding belt can fit on the outer wall of the crystal rod, thereby performing fine grinding operation on the rotating crystal rod. In the above process, the servo motor can also periodically switch forward or reverse, so that the fine grinding belt can be pulled back and forth to further improve the fine grinding effect.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the crystal rod processing device and the use method thereof have a grinding structure with stronger functionality and both flexible and rigid grinding capabilities. The rigid state is used to perform rapid rough grinding on the crystal rod, while the flexible state can perform fine grinding on the surface of the crystal rod, and the processing accuracy of the device is better. The specific contents are as follows: 1. Three one-way teeth with equal angles are fixedly connected to the side wall at the bottom of the limiting ring, and a force-bearing tooth plate is arranged on the side of the outer wall of the limiting ring. A pressure spring is fixedly connected between the end face of the force-bearing tooth plate and the inner wall of the storage box, and the tooth head side of the force-bearing tooth plate is fitted with corresponding one-way teeth to form a one-way limiting structure. There are three grinding shells with equal angles around the screw rod, and the three grinding shells are fitted together to form a complete rigid grinding cylinder structure. A regulating frame is arranged in the middle of the inner wall of the grinding shell, and a connecting arm with an "eight" shape is hinged on the middle horizontal axis of the regulating frame. The end of the connecting arm away from the regulating frame is rotatably connected to the corresponding moving platform, and the upper and lower ends of the screw rod are respectively threadedly connected to the corresponding moving platform to form a transmission structure, so that the screw rod can drive the regulating frame to rotate through the moving platform and the connecting arm. At this time, the regulating frame will drive the grinding shell to rotate synchronously, thereby realizing hard grinding; 2. The flexible fine grinding mechanism includes an outer cylinder, the inner side of the outer cylinder is coaxially rotated with a winding rod, both ends of the winding rod are rotatably embedded in the corresponding engaging blocks, the middle part of the fine grinding belt is located between the outer wall of the loading block and the inner wall of the grinding shell, the middle part of the fine grinding belt is located on the side of the adjacent grinding shell fitting surface, both ends of the fine grinding belt are respectively wound and fixed on the corresponding winding rod, and the fine grinding belt slides through the discharge port of the outer cylinder, when the three grinding shells are away from each other, the fine grinding belt will unfold to facilitate flexible fine grinding of the crystal rod.
