[0018] Example 1, as Figure 1-2 As shown, this utility model provides a technical solution: a drilling fixture for a bearing support, including a drilling base 1, a support plate 2, and a turntable 4. A rotary positioning shaft 3 is mounted inside the drilling base 1 via a bearing, and the turntable 4 is mounted on the outer wall of the rotary positioning shaft 3. An annular slide rail 19 is mounted at the top of the drilling base 1, and a slider adapted to the annular slide rail 19 is mounted at the bottom of the turntable 4. A first arc-shaped groove 7 is formed inside the turntable 4, and a moving block 8 is provided above the turntable 4. A second arc-shaped groove 9 is formed on the side of the turntable 4 away from the first arc-shaped groove 7. A holding block 10 is provided at the top of the turntable 4 above the second arc-shaped groove 9. A limiting mechanism for fixing the position is provided inside the holding block 10 and the moving block 8. The limiting mechanism includes a transverse groove 15 and a positioning screw 16. The transverse groove is formed inside the moving block 8 and the holding block 10. 15. A positioning screw 16 is provided inside the transverse groove 15, which penetrates the first arc-shaped groove 7. A nut block 17 is provided on the outer wall of the positioning screw 16. The outer wall of the nut block 17 engages with the outer wall of the positioning screw 16. A rubber block 18 is sleeved on the outer wall of the positioning screw 16. By moving the positioning screw 16 at the first arc-shaped groove 7 and the transverse groove 15, the positions of the moving block 8 and the holding block 10 are adjusted. By engaging the nut block 17 with the positioning screw 16, and by engaging the rotating displacement screw 14 with the outer wall of the threaded block 13, the triangular tilting block 12 moves within the slide rail 11. The position of the triangular tilting block 12 positions and holds the bearing support body 5. Since the inclinations of the inner sides of the triangular tilting blocks 12 are the same, the position of the bearing support body 5 can be automatically fixed and clamped when clamping the bearing support body 5.

[0019] Example 2, as Figure 1-2As shown, this utility model provides a technical solution: a drilling fixture for a bearing support, including a slide rail 11 mounted on the top of a turntable 4, and a triangular inclined block 12 arranged inside the slide rail 11 through a sliding groove. A bearing support body 5 sleeved on the outer wall of a rotary positioning shaft 3 is arranged between the triangular inclined block 12 and the pressing block 10. A threaded block 13 is installed on the inner wall of a moving block 8, and a displacement screw 14 connected to the triangular inclined block 12 through a bearing is arranged inside the threaded block 13. A first motor 6 is arranged at the bottom of a drilling base 1, and the output end of the first motor 6 is connected to the bottom end of the rotary positioning shaft 3 through a coupling. A support plate 2 is mounted on the top of the drilling base 1, and a second cylinder 23 is arranged at the bottom end of the support plate 2. The output end of the second cylinder 23 is installed with a component connected to the support plate 2. A first cylinder 20 is adapted to the inner sliding groove, and a second motor 21 is installed at the output end of the first cylinder 20. A drilling component 22 is installed at the output end of the second motor 21 through a coupling. By starting the second cylinder 23, the first cylinder 20 is pushed to move in the sliding groove inside the support plate 2, thereby the first cylinder 20 pushes the drilling component 22 to move downward to contact the bearing support body 5. Then, the second motor 21 is started to drive the drilling component 22 to drill holes in the bearing support body 5. When drilling is required in other positions, the first motor 6 is started to drive the rotary positioning shaft 3 to rotate, thereby the rotary positioning shaft 3 drives the turntable 4 to rotate in the annular slide 19, and the turntable 4 drives the bearing support body 5 to rotate, so that holes are drilled in the bearing support body 5.

[0020] Working principle: First, connect the external power supply. The operator can place the bearing support body 5 on the outer wall of the rotating positioning shaft 3, and then move the pressing block 10 to fit under the bearing support body 5. Next, rotate the nut block 17 to engage with the outer wall of the positioning screw 16. After the rubber pad 18 is fixed in place with the turntable 4 and the pressing block 10, the insertion rod can be removed from the moving block 8, and the displacement screw 14 will be separated. Then, rotate the displacement screw 14 to engage with the threaded block 13. The threaded block 13 will drive the triangular tilting block 12 to move within the slide rail 11. The triangular tilting block 12 will then position and press the bearing support body 5. Since the inclination of the inner sides of the triangular tilting blocks 12 is the same, the shaft can be automatically aligned when clamping the bearing support body 5. The bearing support body 5 is fixedly clamped at its position. Finally, the insertion rod can be inserted into the moving block 8 through the displacement screw 14 for easy fixation. The second motor 21 is started to drive the drilling part 22 to drill holes in the bearing support body 5. When drilling is required in other positions, the first motor 6 is started to drive the rotating positioning shaft 3 to rotate. The rotating positioning shaft 3 drives the turntable 4 to rotate in the annular slide 19. The turntable 4 then drives the bearing support body 5 to rotate, thus drilling holes in the bearing support body 5. When the inner and outer diameter positions of the bearing support body 5 need to be adjusted, the second cylinder 23 is started to push the first cylinder 20 to move left and right in the support plate 2, thereby adjusting the left and right drilling positions of the bearing support body 5.

[0021] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
