Embodiment
With reference to Fig. 1 to Fig. 5, a kind of foward-push collet chuck, including collet chuck axle sleeve 1, tapered sleeve 2, collet chuck 3, pull rod device 4 and equipment
Adpting flange 5, the front portion of the collet chuck 3 are provided with chuck 31, and the chuck 31 has a wedge surface one, the equipment adpting flange 5 with
The rear portion of the collet chuck axle sleeve 1 is fixedly connected, and the equipment adpting flange 5 is cyclic structure, and surface is provided with screw, for setting
Standby to be fixedly connected, the collet chuck axle sleeve 1 is the hollow-core construction of both ends open, has one in the middle part of its inwall to the extension of its axle center
Annular support part 11, the both sides of the annular support part 11 are respectively equipped with collet chuck 3 and pull rod device 4, the excircle of the collet chuck 3
Face is provided with the tapered sleeve 2 coordinated with it, and the front inner wall of the tapered sleeve 2 has wedge surface two, the wedge surface two and the phase of wedge surface one
Coordinate, be uniformly provided with some through holes 12 on the annular support part 11, some pins 6 are each passed through the through hole 12 and one
End is fixedly connected with the rear end of the tapered sleeve 2, and its other end is fixedly connected with the pull rod device 4, and the length of the pin 6 is big
In the thickness of the annular support part 11, when the pull rod device 4 moves in the rear end forward end of the collet chuck axle sleeve 1, band
The tapered sleeve 2 is moved to advance and extrude the chuck 31.
As shown in fig. 6, the pull rod device 4 includes the first packing ring 41, branch sleeve 43 and second packing ring 42, the connection
