[0014]pull bar promotes slide mass, at first slide mass slides and promotes on supporting surface that locking body swings Work-sheet pressing and matrix the most at last in locking section, locking section and positioning section have a flex point, slide mass is crossed flex point, in positioning section, slide, locking body is subject to the reaction force of workpiece, produce clockwise moment, cause pull bar to there is the trend swung clockwise, because pull bar and matrix slide through, therefore, matrix has limited the swing of pull bar, and positioning section has been realized the stable position after workpiece locking.Pull bar gives slide mass rightabout power, and the slide mass backhaul discharges workpiece.

the accompanying drawing explanation

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

Fig. 1 is the structural representation (removed storage tank one side part) of workpiece of the present invention in locking state.

The right view that Fig. 2 is Fig. 1.

Fig. 3 is the structural representation (removed storage tank one side part) of workpiece of the present invention in release conditions.

The right view that Fig. 4 is Fig. 3.

In figure: 1 matrix, 2 locking bodies, 3 supporting surfaces, 4 seal faces, 5 inclined plane I, 6 inclined plane II, 7 slide masses, 8 slideways, 9 pull bars, 10 bearing pins, at the bottom of 11 storage tanks, 12 stage clips, 13 workpiece.

The specific embodiment

As shown in Fig. 1～4, a kind of automatic locking positioning device comprises matrix 1 andlocking body 2, matrix has the supportingsurface 3 that bearsworkpiece 13, locking body comprises head and rake, be integrative-structure, locking body has receives the be locked recess of part of workpiece, recess has in turn the workpiece that the connects seal face relative with supporting surface under locking state, with theinclined plane I 5 of extending towards the oblique below of workpiece on the corresponding joint face of thickness of workpiece and rake, rake also has the inclined plane II 6 relative with the inclined plane I, the matrix of the end of rake and supporting surface below is hinged, locking body has theslideway 8 that holdsslide mass 7 and slide for slide mass, slideway has the positioning section that the locking section of extending along inclined plane II direction and workpiece extend along the thickness of workpiece direction under locking state, pullbar 9 slides through matrix and is connected with slide mass and drives slide mass, pull bar is driven by drive unit, there is the storage tank of receiving locking body to swing on matrix.

Above-mentioned automatic locking positioning device, the end of described locking body rake is hinged with matrix by thebearing pin 10 that is set up in the storage tank both sides, when workpiece discharges fully, the inclined plane II of rake with at the bottom of storage tank, 11 contact, matrix has the pilot hole that holds pull bar, and workpiece is under locking state, and pilot hole is identical with the bearing of trend of slideway positioning section, at the bottom of pilot hole one end is communicated with storage tank, the other end forms the bottom outlet mouth.

Above-mentioned automatic locking positioning device, in motion process, described slide mass unanimously moves along the bearing of trend of slideway positioning section.
