[0029] Working principle: When in use, when the inclination angle of the table 106 is adjusted according to the drilling needs, the drive motor 15 is started, and the output shaft of the drive motor 15 drives the second sprocket 14 to rotate. The second sprocket 14 drives the two screw rods 9 to rotate through the chain 16 and the corresponding first sprocket 12. Under the action of the threaded holes opened on the moving rod 8, the two screw rods 9 rotate to drive the two moving rods 8 to move vertically, and the moving rod 8 drives the corresponding guide block 11 to slide on the L-shaped guide rod 10. Since the threads of the two screw rods 9 are rotated in opposite directions, the two moving rods 8 move in opposite directions. When the moving rod 8 on the left moves upward, the moving rod 8 on the right moves downward, and when the moving rod 8 on the left moves upward, the moving rod 8 on the right moves downward. Then the left side of the table 106 is squeezed, so that the table 106 rotates to the right, and the table 106 drives the roller 5 to rotate. When the table 106 rotates, its tilt angle changes. When the required tilt angle is adjusted according to the use needs, the driving motor 15 is stopped, and the moving rod 8 is fixed under the action of the threaded locking force of the threaded hole and the corresponding screw 9 itself, so as to achieve the adjustment and fixation of the tilt angle of the table 106. After the adjustment, the two support rollers 7 support the table 106 on both sides of the bottom. By supporting both sides of the bottom of the table 106 after the adjustment, the support stability is improved, and the situation that the table 106 tilts to one side during the drilling process can be effectively reduced;

[0030] Next, the part to be drilled is placed on the top of the table 106, and then the electric push rod 3 is started forward, and the output shaft of the electric push rod 3 drives the corresponding pressing block 2 to move downward, and the two pressing blocks 2 move downward at the same time to press the part, and then the first electric telescopic rod 102 is started according to the drilling position, and the output shaft of the first electric telescopic rod 102 drives the second electric telescopic rod 103 to move horizontally, and the second electric telescopic rod 103 drives the drilling threaded rod 105 to move horizontally through the driving motor 104. When it is adjusted to the required position, the first electric telescopic rod 102 is stopped, and when drilling, The second electric telescopic rod 103 is started forward, and the output shaft of the second electric telescopic rod 103 drives the driving motor 104 to move downward, and the driving motor 104 drives the drilling threaded rod 105 to move vertically. At the same time, the driving motor 104 is started, and the output shaft of the driving motor 104 drives the drilling threaded rod 105 to rotate. The drilling threaded rod 105 rotates and moves vertically to perform the drilling operation. By driving the two pressing blocks 2 to move vertically to press the parts before drilling, there is no need for manual fixing by personnel, which can effectively reduce the risk of personnel being injured during use and reduce safety hazards.
