[0017] The clamping assembly includes a support plate 9, two guide rails 10, two clamping plates 11, a guide rod 12, and a handwheel 13.

[0019] The driving components include a motor 16, a first gear 17, and a first gear ring 18. The first gear ring 18 is fixedly sleeved on the outer side of the bottom of the ring body 7. The motor 16 is fixedly installed in the base 101. The first gear 17 is fixedly sleeved on the output end of the motor 16 and meshes with the first gear ring 18. The motor 16 has a self-locking function.

[0020] The limiting mechanism includes a linkage component, multiple sets of clamping assemblies, and a suction ring 19. The suction ring 19 is fixedly embedded inside the bottom side of the housing 4. The multiple sets of clamping assemblies are evenly distributed in a ring on the outside of the housing 4. The clamping assemblies include a sleeve 20, a sealing block 21, a screw 22, a screw sleeve 23, and a locking block 24. The end of the sleeve 20 is fixedly installed inside the side wall of the housing 4. The sealing block 21 is slidably fitted inside the sleeve 20. The end of the screw sleeve 23 is fixedly connected to the outer end of the sealing block 21. The screw 22 is rotatably fitted on the end of the sleeve 20 and threadedly fitted with the screw sleeve 23. The locking block 24 is slidably fitted on the inner end of the sleeve 20 and fixedly connected to the end of the sealing block 21. The bottom side of the outer end of the sleeve 20 is fixedly connected to the suction ring 19 through a conduit 25.

[0021] The linkage components include multiple second gears 26, a second gear ring 27, multiple clamps 28, a motor 29, a frame 30, and a third gear 31. The multiple second gears 26 are respectively fixedly installed on the outer ends of multiple screws 22. The multiple clamps 28 are all vertically fixedly installed on the bottom of the support plate 9 and are evenly distributed in a ring. The second gear ring 27 is rotatably embedded in the bottom end of the multiple clamps 28 and meshes with the multiple second gears 26. The frame 30 is fixedly connected to the inner side of one of the clamps 28. The motor 29 is fixedly installed in the frame 30. The third gear 31 is fixedly installed on the output end of the motor 29 and meshes with the second gear ring 27. The motor 29 has a self-locking function.

[0022] When using this equipment to perform hole machining on a workpiece, the workpiece is placed between two clamping plates 11, and the handwheel 13 is turned. The handwheel 13 drives the guide rod 12 to rotate, and the two clamping plates 11 are brought closer together through the thread to clamp the workpiece.

[0023] After the workpiece is fixed, the equipment is operated through the control panel. First, the angle of the workpiece is adjusted. The three telescopic cylinders 6 are activated through the control panel. The three telescopic cylinders 6 extend or retract, causing the top ball bearings 8 to rise or fall, so that the three points of the top tips of the three ball bearings 8 are at different heights. Since the three ball bearings 8 are not on a straight line, the vertices of the three ball bearings 8 determine a plane. Since the lengths of the three telescopic cylinders 6 are different, an inclined surface is formed.

[0024] All three balls 8 are in contact with the bottom side of the support plate 5, which causes the support plate 5 to drive the sleeve 4 to deflect on the ball 3, thereby causing the support plate 9 to form an inclined surface, thus causing the workpiece to be in an inclined state. When it is necessary to change the inclination angle of the workpiece, it is only necessary to adjust the length of the three telescopic cylinders 6 to make the clamping assembly obtain different inclination angles, thereby causing the workpiece to deflect. There is no need to adjust the relative position between the workpiece and the clamping plate 11, so that the angle between the workpiece and the drill bit can be flexibly adjusted for inclined hole operation.

[0025] After the length of the telescopic cylinder 6 is adjusted and its height is fixed, the motor 16 is started. The motor 16 drives the first gear ring 18 to rotate through the first gear 17. The first gear ring 18 drives the ring body 7 to rotate. The ring body 7 drives the three telescopic cylinders 6 located on it to rotate. With the support of the ball bearing 8, the support plate 5 drives the sleeve 4 to rotate on the ball 3 at a certain fixed tilt angle, thereby realizing a 360-degree adjustment of a certain tilt angle, which makes it easier to adjust the tilt orientation of the workpiece. Since the friction between the sleeve 4 and the ball 3 is greater than the friction between the ball bearing 8 and the bottom surface of the support plate 5, the support plate 5 will not rotate with the ball bearing 8.

[0026] After the tilt angle of the workpiece is adjusted, the motor 29 is started. The motor 29 drives the second gear ring 27 to rotate through the third gear 31. The second gear ring 27 drives multiple second gears 26 to rotate simultaneously. The second gears 26 drive the screw 22 to deflect. The screw 22 drives the screw sleeve 23 to move. The screw sleeve 23 drives the sealing block 21 to move. The sealing block 21 drives the locking block 24 to move closer to the ball 3. Finally, the locking block 24 tightly abuts against the ball 3, so that the relative position between the sleeve 4 and the ball 3 is fixed, thereby realizing the position limitation of the workpiece, which is convenient for the drill bit to perform drilling operations.

[0027] When the motor 29 drives the locking block 24 to approach the ball 3, the sealing block 21 moves closer to the ball 3 and draws the air in the suction ring 19 into the sleeve 20 through the conduit 25, so that the suction ring 19 is adsorbed on the ball 3, thereby further restricting and fixing the sleeve 4.

[0028] After the position is adjusted, both motor 16 and motor 29 stop running and are in a self-locking state.

[0029] With the cooperation of the limiting mechanism, multiple clamping blocks 24 on the upper side of the sleeve 4 are pressed and fixed to the ball 3, and the bottom side is attracted and fixed to the ball 3 by the suction ring 19, realizing the limiting structure of upper clamping and lower suction, thereby realizing the relative fixation of the position between the sleeve 4 and the ball 3, so that the workpiece position is fixed, preventing the workpiece from moving during drilling operations and ensuring processing accuracy.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
