Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is top view of the present utility model;

Fig. 2 is structural representation of the present utility model;

Fig. 3 is the perspective view of position-limit mechanism of the present utility model;

Fig. 4 is the perspective view that ejects material fetching mechanism of the present utility model.

The specific embodiment:

The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.

Embodiment; see accompanying drawing 1 ~ 4; small-sized hollow part precise positioning carrier; comprise base 1, position-limit mechanism I and eject the material fetching mechanism II; described base is provided with an anti-shape boss 2, and part 3 is placed on the anti-shape boss, and the profile of anti-shape boss is the opening profile in the middle of the part; mainly prevent the part rotation, shield simultaneously.

Described position-limit mechanism I is by pressing plate 4, locating piece 5, bulb plunger 6, retainer spring 7 and shake hands 8 to form, and described base is provided with a groove identical with the locating piece width, and locating piece is placed in the groove, can slide before and after groove; Described locating piece front is 90 ° V-arrangement, for an angle of withstanding part, clamps part; Fill a pressing plate on the described locating piece, and pressing plate is locked on the base, is used for preventing that locating piece from coming off; The groove of described base has a pit a9, the locating piece bottom surface is provided with a boss 10, retainer spring is equipped with in the boss front, boss and retainer spring all place in the pit a, thus, under the effect that does not have external force, locating piece is in to the state that protracts because of the elastic force of spring always, thereby clamp part part is accurately located, the power that is equivalent to clamp part is exactly elastic force.One handle is housed on the described locating piece; Described locating piece bottom surface is provided with an arc groove 11; Described bulb plunger is contained on the base; When picking and placeing part, locating piece need to unclamp, need to use the arc groove of handle, bulb plunger and locating piece bottom surface this moment, the bulb of bulb plunger top is flexible, the bulb piece compression that is positioned is in compressive state when clamping part, after locating piece is pulled back certain distance, arc groove can be moved the position of bulb plunger to, and bulb is no longer compressed, is ejected in the groove, locating piece is no longer to reach, at this moment pick and place part with regard to cocoa, when needing locating element, again locating piece is pushed away forward, state before locating piece returns, reciprocal thus.

Because the centre of part rest area is anti-shape boss, so part is put into easily, but be not easy to take out, just part need to be ejected this moment and prevent the shape boss.

The described material fetching mechanism II that ejects is comprised of knock pin 12, mounting blocks 13, spring 14, rotating shaft 15, spill spin block 16, button connecting axle 17 and button 18, described base end face is provided with a pit b19, in the pit b rotating shaft is housed, fills spill spin block on the rotating shaft, spill spin block rotates along rotating shaft; Described mounting blocks places the spill spin block top, and three knock pins and spring are housed on the mounting blocks, is provided with and three three holes that knock pin is corresponding at the part lay down location on the described base; Described button connecting axle lower end contacts with spill spin block, and the upper end passes base and button links together.When not being subjected to the state of external force, mounting blocks is in lowermost end because of elastic force, the corresponding bottom that is in of knock pin, spill spin block one end is spacing by base, other end contact mounting blocks, with button toward pressing down, the button connecting axle is simultaneously to moving down, the spill spin block rotation, mounting blocks moves up, and knock pin upwards moves simultaneously, part is ejected, state before release-push, knock pin will recover, reciprocal thus.
