[0017] Reference Figure 1 , Figure 2 The utility model provides a rapid positioning mechanism for a drilling machine, including a support plate 1, a lifting drill 2, a positioning cylinder 3 and a hole cleaning mechanism 4 are installed on the upper surface of the support plate 1, the positioning cylinder 3 and the hole cleaning mechanism 4 are installed on both sides of the lifting drill 2, a through hole matching with the lifting drill 2, the positioning cylinder 3 and the hole cleaning mechanism 4 is opened on the support plate 1, a material guide groove 5 is arranged on the lower surface of the support plate 1, a feeding hole 501 is opened at one end of the material guide groove 5, a pushing cylinder 14 is installed on the support plate 1, a push rod 15 is arranged in the material guide groove 5, the push rod 15 is connected with the piston rod of the pushing cylinder 14, an axle pin 16 enters the material guide groove 5 from the feeding hole 501 through the vibrating loading plate, and then the pushing cylinder 14 pushes the axle pin 16 to the bottom of the positioning cylinder 3, and the piston rod of the positioning cylinder 3 extends to press the axle pin 16 against the bottom of the material guide groove 5.

[0018] The support plates 1 on both sides of the material guide trough 5 are respectively installed with an advance and retreat cylinder 9 and a material clamping cylinder 12. Two material clamping columns 13 are slidably installed on one side of the material guide trough 5 adjacent to the material clamping cylinder 12. The two material clamping columns 13 are respectively installed below the positioning cylinder 3 and the lifting drill 2;

[0019] An advance and retreat groove 101 is provided on the support plate 1 between the material guide groove 5 and the advance and retreat cylinder 9, and a guide column 7 is installed in the advance and retreat groove 101. An advance and retreat block 6 is provided on the guide column 7. The piston rod of the advance and retreat cylinder 9 is connected to the advance and retreat block 6 to drive it to approach or move away from the material guide groove 5. A material transfer slide 8 and a material transfer cylinder 11 are installed on the advance and retreat block 6. The piston rod of the material transfer cylinder 11 is connected to the slider of the material transfer slide 8. Two clamping cylinders 10 are installed on the slider of the material transfer slide 8. The spacing between the two clamping cylinders 10 is equal to the spacing between the two clamping columns 13.

[0020] During operation, after the axle pin 16 is pushed to the bottom of the positioning cylinder 3, the piston rod of the positioning cylinder 3 extends, and the positioning column (not shown) thereon presses the axle pin 16 against the bottom of the material guide trough 5, and the clamping cylinder 12 pushes the clamping column 13 to press and fix the side of the axle pin 16, and then the advance and retreat cylinder 9 drives the clamping cylinder 10 to move the material guide trough 5 to clamp the axle pin 16, and the material moving cylinder 11 pushes the slider of the material moving slide rail 8 to move, thereby moving the axle pin 16 to the bottom of the lifting drill 2 and the hole cleaning mechanism 4.

[0021] Through the action of the positioning cylinder 3 and the clamping cylinder 12, the shaft pin 16 is closely contacted and positioned with the bottom and one side wall of the material guide trough 5, thereby avoiding vibration and displacement of the shaft pin 16 when the lifting drill 2 is drilling, thereby ensuring the quality of the finished product and avoiding damage to the drill bit of the lifting drill 2; in addition, since the material guide trough 5 is arranged on the lower surface of the support plate 1, the metal debris generated by the drilling naturally falls to the bottom of the support plate 1 during the processing, avoiding accumulation on the upper surface of the support plate 1 and affecting the operation of the lifting drill 2.
