Abstract
The utility model relates to a spiral auxiliary pin puller. The left and right ends of a stay bar are respectively provided with an internal thread, and the internal threads have opposite spiral directions; the interior of the left-hand thread is in threaded connection with a baffle; the lower part of the baffle is connected with a fixed supporting point; the right-hand thread at the other side of the stay bar is in threaded connection with a threaded pin with a boss; the outer end of the threaded pin is connected with a fork lug; The middle of the stay bar is provided with a through hole; the through hole is internally provided with a manual rotary pin. The spiral auxiliary pin puller is not only simple in structure, but also rapid in pin pulling speed, and thus can be used for improving the working efficiency.
Description
Technical field
The utility model relates to the auxiliary pin removal of a kind of spiral, for assembling the dismounting of field alignment pin.
Background technology
Part, in the time of assembling, needs alignment pin location, after assembling, and rainy rigging error accumulative total sometimes, artificial unloading's alignment pin is time-consuming, effort.
Summary of the invention
The technical problems to be solved in the utility model is to provide the auxiliary pin removal of a kind of spiral, and the auxiliary pin removal of this spiral is not only simple in structure, and the speed of pulling pin is fast, thereby has improved operating efficiency.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of spiral is assisted pin removal, two ends, left and right at strut are respectively equipped with the internal thread that the hand of spiral is contrary, connect baffle plate at left hand thread internal thread, and the below of baffle plate is connected with fixing fulcrum; Opposite side right-handed thread internal thread at strut connects the threaded with boss, threaded outer end yoke ear; Centre at strut is provided with through hole, is provided with manual rotation pin in through hole.
The auxiliary pin removal of this spiral adopts said structure, can position one end of strut by fulcrum, by the rotation of manual rotation pin, can listen the screw-in of the fork ear of opposite side, and by fork ear, pin is extracted.
Brief description of the drawings
Fig. 1 is the structural representation of the auxiliary pin removal of spiral.
Fig. 2 is that the C of Fig. 1 is to view.
Fig. 3 is that the D of Fig. 1 is to view.
Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of spiral is assisted pin removal, is respectively equipped with at the two ends, left and right of strut 2 internal thread that the hand of spiral is contrary, connects baffle plate 5 at left hand thread internal thread, and the below of baffle plate 5 is connected with fixing fulcrum 6; Opposite side right-handed thread internal thread at strut 2 connects the threaded 1 with boss, threaded 1 outer end yoke ear 7; Centre at strut 2 is provided with through hole, is provided with manual rotation pin 3 in through hole.
In use, the fork ear 7 that is threaded pin is inserted on alignment pin to be removed 4, then the dextrorotation part of strut 2 is flexibly connected with threaded 1, left-handed part is connected with the threaded portion of baffle plate 5, and baffle plate 5 is fixedly connected with fulcrum 6, manual rotation pin 3 is rotated, threaded 1 is under the effect of the revolving force of strut 2, move to the right, thereby alignment pin to be removed 4 is extracted from part.
