Summary of the invention
The utility model provides a kind of powerful pull feeder.
For achieving the above object, the technical solution adopted in the utility model is: a kind of powerful pull feeder, comprises the gentle source supply device of cylinder, and sliding in the cylinder chamber of described cylinder is provided with a piston, and this piston is stretched towards the side of the front end housing of cylinder and is provided with pawl in two; Pawl interval in described two and be symmetricly set on described piston, slide and be provided with two outer pawls in the outside of the front end housing of described cylinder, the corresponding described interior pawl of this outer pawl is provided with the pilot hole matched with interior pawl profile, the pilot hole that described interior pawl stretches into described outer pawl is arranged, and two air supply pipes of described source of the gas feeding mechanism are communicated to the cylinder chamber of described piston both sides respectively.
Preferred technical scheme is: the end defining described interior pawl and piston fixing is stiff end, and the other end is free end, in described two pawl free end between distance be greater than pawl in two stiff end between distance.
Preferred technical scheme is: described source of the gas feeding mechanism is air compressor.
Preferred technical scheme is: the front end of described outer pawl is fixed with the claw treating insert product in order to clamping.
Preferred technical scheme is: the surface of the connecting portion of described outer pawl and claw is provided with serration.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the pressure of the present invention's gas of utilizing source of the gas feeding mechanism to provide promotes piston movement, then utilizes lever principle to perform holding action, so chucking power is large, and chucking power can adjust;
2, the degree of tightness of claw of the present invention completes by cylinder, so surface of the work can not be damaged;
3, pressure adjustable joint of the present invention, can regulate pressure according to actual conditions.
