Detailed Description

Referring to fig. 1-7, the clamping mechanism of the full-automatic screw driving machine of the present invention comprises a finger cylinder 1 (also known as a pneumatic finger, a pneumatic clamping jaw or a pneumatic clamping finger) and a clamping jaw 3 mounted on a clamping arm 2 of the finger cylinder 1. The clamping jaw 3 comprises a clamping seat 4 and a clamping finger 5, wherein the clamping seat 4 is arranged oppositely, and the clamping finger 5 is arranged on the clamping seat 4.

And a longitudinal through hole 6 is arranged between the clamping seat 4 and the clamping finger 5. A screwdriver head 7 (a screwdriver head arranged on an electric hand drill or an electric screwdriver) is arranged in the through hole 6. The upper end of the clamping finger 5 is rotatably connected with the clamping seat 4, and the upper end of the clamping finger 5 is provided with an elastic part 8, so that the lower end of the clamping finger 5 can deflect left and right. When a force is applied to the lower end of the clamping finger 5 to the left side, the lower end of the clamping finger 5 can be deviated along with the force.

Preferably, the bottom of the clamping seat 4 is provided with a mounting groove 9, one side of the upper end of the clamping finger 5 is mounted in the mounting groove 9 through a rotating shaft 10, a gap 11 is formed between the upper end surface of the clamping finger and the mounting groove 9, and the other side of the upper end of the clamping finger 5 is provided with an elastic part 8. The elastic member 8 is a spring. By the structure, the clamping finger 5 can be deviated, and the stability of the clamping finger 5 in the clamping seat 4 is ensured.

Preferably, the lower end of the clamping finger 5 is provided with a circular groove 12 and a square groove 13. Through the cooperation of circular groove 12 and square groove 13, can be simultaneously fixed the circular spiral shell head 19 at screw 18 top and the square gasket 20 that sets up on the screw 18 simultaneously to the realization is got the screw clamp that has gasket (or tile), guarantees simultaneously to get the stability of getting.
