Multiple square positioning through hole are provided with wall, is matched in the positioning through hole and is fitted with tensioning block, the outer end of the tensioning block
For tight lifting pin shaft sleeve workpiece, the inner of the tensioning block is inclined plane, and the inclined plane and the mandril in hollow-core construction
Slopes which match, is moved by the mobile promotion tensioning block of mandril in positioning through hole, realizes clamping and the pine of pin sleeve workpiece
Open, one end of the mandril is contacted with the end of adjusting screw rod, and the other end of the mandril is provided with resetting spring.
Multiple positioning through hole circumferentially array distribution in hollow-core construction.
It is in hollow-core construction that the locating shaft is overall, and the both ends of the locating shaft are both provided with adjusting screw rod, the adjusting
The end of screw rod is both provided with mandril, and resetting spring is provided between two mandrils, and each mandril corresponds to one group of tensioning
Block, for holding out against corresponding pin sleeve workpiece.
The utility model has an advantageous effect in that compared with prior art：The utility model can be good at improving axis pin
The shortcomings that set is difficult to remove positioning tool because of welding deformation, significantly improves the dimensional accuracy of spot-welded, improves production
Efficiency.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
In figure：1 it is locating shaft, 2 be adjusting screw rod, 3 be positioning through hole, 4 be tensioning block, 5 be pin sleeve workpiece, 6 is multiple
