[0021] Please refer to Figures 1-5 ;

[0022] A high-safety training five-axis turntable includes a left fixed base 1, a right fixed base 2, and a base 3. The left fixed base 1 and the right fixed base 2 are respectively provided with a left rotating shaft 11 and a right rotating shaft 21. The centers of the left rotating shaft 11 and the right rotating shaft 21 are respectively provided with a corresponding left fixed shaft 12 and a right fixed shaft 22. Preferably, the left fixed shaft 12 and the right fixed shaft 22 have the same structural dimensions and are both on the same horizontal plane. The two ends of the base 3 are fixedly connected to the left fixed shaft 12 and the right fixed shaft 22, respectively. The outer ends of the left fixed shaft 12 and the fixed shaft extend... Outside the left fixed seat 1 and the right fixed seat 2, the outer end of the right fixed shaft 22 is provided with a drive assembly 23 to drive its rotation. The drive assembly 23 drives the right fixed shaft 22 to rotate. Since the base 3 is connected to the right fixed shaft 22, when the right fixed shaft 22 rotates, the entire base 3 also rotates, realizing the rotation function along the axial direction of the right fixed shaft 22. A main rotating shaft 4 is vertically mounted on the base 3, and a turntable 5 is mounted on the main rotating shaft 4. A fixture (not shown in the figure) is mounted above the turntable 5 to clamp the workpiece for processing. The turntable 5 is located on the left fixed seat 1. The outer end is equipped with a second drive assembly 13 that drives the main rotating shaft 4 to rotate. By driving the main rotating shaft 4 through the second drive assembly 13, the turntable 5 and the fixture on it can rotate together, so as to adjust the angle of the workpiece for processing.

The lower end face of the silicone sleeve 34 contacts the bottom of the annular groove 51. Through the action of the rollers 33 and the silicone sleeve 34, the vibration of the turntable 5 during processing can be reduced. The silicone sleeve 34 reduces wear on the turntable 5 during rotation, improving the safety, stability, and processing accuracy of the equipment. In addition, the silicone sleeve 34 reduces wear on the roller 33 itself and reduces noise emitted by the roller 33 when the turntable 5 rotates. When the silicone sleeve 34 wears out after long-term use, the telescopic end of the telescopic cylinder 32 can be retracted to allow the output shaft to exit the annular groove 51. Then, a new silicone sleeve 34 can be replaced, and the telescopic end of the telescopic cylinder 32 can be extended to allow the roller 33 to return to the annular groove 51 and contact the bottom surface of the annular groove 51, ensuring the effective fixing of the turntable 5.

The size of the positioning grooves 31 matches the size of the telescopic cylinder 32 and is used for positioning the telescopic cylinder 32. The cylinder can be directly placed into the corresponding positioning groove 31 to complete the initial positioning without additional measurement or adjustment. When fixing the telescopic cylinder 32 with screws from the bottom of the base 3, there is no need to frequently correct the position, which improves the installation speed and ensures the consistency of each installation.
