The specific embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, and namely the simple equivalent of being done with the utility model claim and description in every case changes and modifies, and all still belongs within the utility model patent covering scope.
As shown in Figure 1, 2, 3, a kind of scroll chuck detent mechanism, comprise pedestal 1, in described pedestal, be provided with driving mechanism 2 and the outside by the intermeshing main drive gear 3 of teeth and auxiliary driving gear 4, described driving mechanism can drive described main drive gear around its axis rotation, and described auxiliary driving gear centre is formed for placing the cavity 41 of product 11 to be positioned; Be provided with the cover plate 5 that is fixed on the described pedestal at described auxiliary driving gear lateral surface, at interval form three respectively along the chute 6 of described auxiliary driving tooth radius direction on this cover plate, be movably equipped with a slide block 7 that can move along this chute in this each chute; Also be interval with three jaws 8 that point to its axle center respectively on the described auxiliary driving gear lateral surface, these three jaws are away from an end of the described auxiliary driving gear axis end of three slide blocks near described auxiliary driving gear axis that be connected respectively; Corresponding described three jaw position places are provided with an identical deep-slotted chip breaker 9 respectively on the described auxiliary driving gear lateral surface, and the distance of this deep-slotted chip breaker from the one end to described auxiliary driving gear axis diminishes gradually to the distance of the other end to described auxiliary driving gear axis; Also be installed with a cam bawl 10 respectively near described auxiliary driving gear one side on described three slide blocks, the other end of this cam bawl is inserted in the described deep-slotted chip breaker respectively and can slides along this deep-slotted chip breaker.During work, start driving mechanism and drive the main drive gear rotation, main drive gear since its outside and the auxiliary driving gear be connected with a joggle by teeth, therefore the transmission meeting of main drive gear drives this auxiliary driving gear rotation, because three slide blocks are limited in respectively in three chutes, three cam bawl other ends are limited in respectively in three deep-slotted chip breakers and slide simultaneously, three cam bawls slided along this deep-slotted chip breaker in three deep-slotted chip breakers respectively when therefore the auxiliary driving gear rotated, because being gradually to the distance of auxiliary driving gear axis, three deep-slotted chip breaker one ends and the other end reduce, can drive three jaws when therefore three cam bawls move respectively respectively to close auxiliary driving gear axis or away from the motion of auxiliary driving gear axis direction in three deep-slotted chip breakers, and then realize the clamping of jaw and open action.Status architecture schematic diagram when as shown in Figure 4, clamping product for this scroll chuck detent mechanism.
