[0022] Refer to Figures 1 - 3 , a clamping and positioning tooling for processing a guiding seat, including a frame body 1. An adjustable punching component is installed on the upper surface of the frame body 1. A base 2 is fixed on the upper surface of the frame body 1 by bolts. A rotating groove 13 is opened inside the base 2. A turntable 22 is rotatably connected inside the rotating groove 13. A fixing frame 8 is fixed on one side of the turntable 22 by bolts. A rotating shaft is rotatably connected inside the fixing frame 8. One end of the rotating shaft is key-connected with a first bevel gear 7. A plurality of fixing blocks 6 are fixed on the outer wall of one side of the turntable 22 by bolts. A lead screw 10 is rotatably connected inside the fixing block 6. One end of the lead screw 10 is key-connected with a second bevel gear 9, and the first bevel gear 7 meshes with the second bevel gear 9. A plurality of first chutes 11 are opened inside the turntable 22. A support rod 12 is slidably connected inside the first chute 11, and the support rod 12 passes through the first chute 11 and is threadedly connected with the lead screw 10. The circular guiding seat to be positioned is sleeved outside between the plurality of support rods 12. Then, the first bevel gear 7 is rotated to drive the plurality of second bevel gears 9 to rotate, so that the lead screw 10 drives the support rods 12 to move outward respectively until the support rods 12 are in close contact with the inner wall of the circular guiding seat, thereby clamping and positioning the circular guiding seat. A fixing component for restricting the rotation of the turntable 22 is provided inside the base 2.

[0023] In the present utility model, it should be noted that the fixing component includes a second chute 14 which is opened inside the base 2. A plug frame 4 is slidably connected in the second chute 14. A spring 3 is sleeved outside the plug frame 4, and both ends of the spring 3 are fixed to the plug frame 4 and the second chute 14 respectively. A plurality of jacks 5 are opened on the circumferential outer wall of the turntable 22, and the top end of the plug frame 4 is inserted into the jack 5. When it is necessary to adjust the position of the circular guide seat to be polished, press down the plug frame 4 to make it move downward along the second chute 14, and the spring 3 contracts until the top end of the plug frame 4 moves out of the jack 5. Then rotate the turntable 22 to change the position of the circular guide seat. Release the plug frame 4, and the spring 3 rebounds and resets to make the plug frame 4 insert into the jack 5 at the corresponding position, thereby fixing the rotated turntable 22 again. The drilling component includes two guide rails 17 which are fixed to the upper surface of the frame body 1 by bolts. A U-shaped frame 21 is slidably connected between the two guide rails 17. The guide rails 17 can guide the U-shaped frame 21 to move stably. A third chute 20 is opened inside the U-shaped frame 21. A threaded rod 16 is rotatably connected inside the third chute 20.

[0024] Working principle: When positioning the circular guide seat, first put the circular guide seat to be positioned outside between multiple support rods 12, and then rotate the knob to drive the second bevel gear 9 to rotate by the first bevel gear 7, so that the lead screw 10 drives the support rods 12 to move outward respectively until the support rods 12 are in close contact with the inner wall of the circular guide seat, thereby clamping and positioning the circular guide seat. When grinding the guide seat, rotate the threaded rod 16 to drive the carriage 15 to move downward along the third chute 20, so that the drill bit moves to the corresponding position where the circular guide seat needs to be ground. Then start the motor, and the drill bit rotates to push the U-shaped frame 21 to move along the guide rail 17, so that the drill bit grinds the guide seat. When adjusting the position where the circular guide seat is to be ground, press down the insertion frame 4 to move it downward along the second chute 14, and the spring 3 contracts until the top end of the insertion frame 4 moves out of the insertion hole 5. Then rotate the turntable 22 to change the position of the circular guide seat. Release the insertion frame 4, and the spring 3 rebounds and resets to insert the insertion frame 4 into the insertion hole 5 at the corresponding position, thereby fixing the rotated turntable 22 again.
