This equipment is relatively high in price, and if higher precision and more complex shape are to be achieved, more expensive configurations are needed. For existing inventory equipment, it is difficult to complete complex modification work, and the cycle is long. Usually, the grinding wheel is modified by custom-made modification device, but this way is high in cost, long in cycle, poor in precision control and cannot be adjusted. SUMMARY

[0018] Wherein, servo motor Z axis 9 and servo motor X axis 2 can be moved by moving slide, and drive moving platform to realize two-dimensional motion.

[0019] In the embodiment, various special-shaped grinding wheels or tools for similar purposes can be flexibly ground without customizing special tooling fixtures.

[0020] Wherein, upper and lower slide 10 and translation slide 4 can be moved on moving device by ball screw.

[0021] In the embodiment, the platform is more stable during movement.

[0022] Wherein, speed reducer 17 can stabilize the power transmitted from servo motor A axis 14 to a certain value.

[0023] In the embodiment, the swing arm is prevented from being damaged at too fast speed.

[0024] The swing arm 18 drives the pen seat under the drive of the motor, so that the grinding tool 20 makes circular motion around the center axis of the speed reducer 17.

[0025] In the embodiment, the top position of the grinding tool is always at the position of the moving circle center during the motion, which not only improves the grinding of various shapes, but also ensures the continuity during the grinding.

[0028] Working principle: before starting, the grinding part is fixed on the rotating chuck of the machine tool, and after the machine tool is started, the grinding part makes circular rotation and friction cutting with the top end of the grinding tool 20. The swing arm 18 drives the pen seat under the drive of the motor, so that the grinding tool 20 makes circular motion around the center of the top tip. With the cooperation of the industrial camera 21, the grinding part tip of the top of the grinding tool 20 is adjusted to the circle center during the circular motion of the grinding tool 20, so that the subsequent process can be smoothly carried out. After the debugging is completed, the prepared data is imported into the machine, and then the machine is driven by the servo motor X shaft and the servo motor Z shaft, and the translation platform and the upper and lower moving platform are used to transport the grinding device to the specified position. Then, according to the required grinding shape, the swing arm starts to make circular motion, so as to continuously adjust the posture of the grinding tool. At the same time, the industrial camera 21 feeds back the working state in real time, not only to observe whether the turning state meets the expectation, but also to check whether the top position of the grinding tool deviates. After the grinding is completed, the translation platform and the upper and lower moving platform will return to the initial position under the drive of the servo motor, and wait for the next grinding object.
