Summary of the invention:
The technical problem to be solved in the present invention is: a kind of anchor clamps that workpiece with cavity is fixed are provided.
In order to solve the above problems, the invention provides a kind of inner stationary fixture, comprise clip base, bearing pin, power arm; rocking arm, rocker arm shaft, fixed head; returning spring; slip clamp axle and reply pin, it is T-shaped that clip base becomes, its inside is provided with the cavity that cooperates with described bearing pin; described fixed head is horizontally arranged with sliding tray and spring holddown groove; middle place is provided with the hole corresponding with described cavity, and described returning spring is fixed in the spring holddown groove, about described slip clamp axle is divided into two; and be arranged in the sliding tray; reply pin and be arranged on the fixed head, wherein reply pin and returning spring and be weldingly connected, described sliding clamp and clip base are threaded; described bearing pin one end is provided with the frustum of a cone; bottom this bearing pin and described rocking arm ball-type hinged, the other end of rocking arm is connected with power arm, described rocker arm shaft is hinged on the clip base.
Use the inside stationary fixture of technical solution of the present invention that following benefit is arranged: 1, because bearing pin one end is provided with the frustum of a cone, this bearing pin bottom and described rocking arm ball-type are hinged, and the other end of rocking arm is connected with power arm; rocker arm shaft is hinged on the clip base, use power arm can drive bearing pin and move up and down; 2, because bearing pin one end is provided with the frustum of a cone, bearing pin moves up and down in the process, and the frustum of a cone as long as fix the power arm end, just can fix workpiece by fixing inner chamber so that described slip clamp axial-radial moves; 3, because described returning spring is fixed in the spring holddown groove, described slip clamp axle is arranged in the sliding tray, replys pin and is arranged on the fixed head, replys pin and links to each other with returning spring, its objective is to allow the slip clamp axle have one to automatically reply function; 4, because sliding clamp and clip base are threaded, can conveniently install and take out slip clamp axle and interior fittings.
Further, for so that described returning spring and reply pin and can conveniently weld, described answer pin and returning spring weld are set to the plane.
Further, in order to strengthen anchor clamps to the arc inner chamber chuck(ing) capacity of workpiece, the jaw of described slip clamp axle is set to concave surface.
At last, for so that rocking arm and power arm junction do not produce interference, described rocking arm and power arm tie point place are provided with bar hole, and the power arm corresponding section is provided with fixed pin shaft; when rocking arm rotates around rocker arm shaft, and bar hole can play the relative position of adjusting rocking arm and power arm.
Description of drawings:
Fig. 1 is the structural representation of the inner stationary fixture of the present embodiment;
Fig. 2 is the top view of Fig. 1.
The specific embodiment:
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As depicted in figs. 1 and 2: inner stationary fixture, comprise clip base 6, bearing pin 3, power arm 7, rocking arm 10; rocker arm shaft 9; fixed head 1, returning spring 2, slip clamp axle 5 and reply pin 4; 6 one-tenths of clip base are T-shaped; its inside is provided with the cavity that cooperates with bearing pin 3, and fixed head 1 is horizontally arranged with sliding tray and spring holddown groove, and middle place is provided with the hole corresponding with cavity; returning spring 2 is fixed in the spring holddown groove; about slip clamp axle 5 is divided into two, and be arranged in the sliding tray are replied pin 4 and are arranged on the slip clamp axle 5; wherein answer sell 4 and returning spring 2 be weldingly connected; slip clamp axle 5 and clip base 6 are threaded, and bearing pin 3 one ends are provided with the frustum of a cone, and the bottom of this bearing pin 3 and rocking arm 10 ball-types are hinged; the other end of rocking arm 10 is connected with power arm 7, and rocker arm shaft 10 is hinged on the clip base 6.
Bearing pin 3 one ends are provided with the frustum of a cone, and the bottom of bearing pin 3 and rocking arm 10 ball-types are hinged, and the other end of rocking arm 10 is connected with power arm 7, and rocker arm shaft 9 is hinged on the clip base 6, use power arm 7 can drive bearing pin 3 and move up and down; Bearing pin 3 moves up and down in the process, the frustum of a cone so that slip clamp axle 5 to radially mobile, the jaw place radius of circle of two slip clamp axles 5 increases, so that slip clamp axle 5 clamping work pieces, as long as fix power arm 7 ends this moment, just can fix workpiece by fixing inner chamber; Returning spring 2 is fixed in the spring holddown groove, slip clamp axle 5 is arranged in the sliding tray, replying pin 4 is arranged on the slip clamp axle 5, replying pin 4 links to each other with returning spring 2, its objective is and allow the slip clamp axle have one to automatically reply function, because slip clamp axle 5 and clip base 6 are threaded, and can conveniently install and take out slip clamp axle 5 and interior fittings.
