Specific works principle is as follows: first the stiff end of fixed bar and manikin head are fixed, now screw rod is towards the installing port of manikin head, by dummy neck as installing port place, rotating screw bolt make the end of mounting blocks and dummy neck against, be rotated further screw rod, mounting blocks promotes the installing port that dummy neck is pushed to manikin head by dummy neck, thus completes the installation of dummy neck and manikin head; Above-mentioned steps can complete by means of only a people, therefore enormously simplify the mounting complexity of dummy neck, can be completed the installation of dummy neck by rotating screw bolt, handles simple and can realize the installation of dummy neck fast; Rotating screw bolt can the displacement of fine adjustment dummy neck, also just can control dummy neck decrement accurately, ensure that the consistance that dummy neck is installed, thus improve accuracy and the reliability of collision experiment data.
In the auxiliary installation device of above-mentioned dummy neck, the extended line of described screw rod and the extended line of fixed bar have intersection point.When installing dummy neck fixed bar and the center line of manikin head's installing port coplanar, this structure make screw rod and fixed bar coplanar, the acting force making screw rod be applied to dummy neck linearly acts on dummy neck.
In the auxiliary installation device of above-mentioned dummy neck, the relative fixed bar of described kink is obliquely installed, and described screw rod is mutually vertical with between kink, and have angle a between described kink and fixed bar, the size of described angle a is 95 ° ~ 105 °.Have certain angle between manikin head and neck, said structure can ensure that the acting force of screw rod when neck being pressed into the installing port of manikin head linearly acts on neck.
In the auxiliary installation device of above-mentioned dummy neck, described mounting blocks is cylindrical, one end of described mounting blocks has groove, the groove bottom of described groove has fixed orifice, the other end end face of described screw rod and mounting blocks against, described mounting blocks is fixed through fixed orifice and screw rod by bolt.Said structure can mounting blocks for convenience detach.
In the auxiliary installation device of above-mentioned dummy neck, the stiff end of described fixed bar is fixed with fixed head, described fixed bar is parallel with fixed head, and described fixed head has connecting hole.Manikin head has installed surface, installed surface has mounting hole, fixed head can be fitted to be fixed on installed surface and connecting hole is alignd with mounting hole and is connected, and fixed head is fixed on manikin head through connecting hole and mounting hole by bolt.
In the auxiliary installation device of above-mentioned dummy neck, described screw rod is fixed with manual pulley away from one end of stiff end.Manual pulley energy handled easily person rotating screw bolt, and rapid operation.
Compared with prior art, the auxiliary installation device of this dummy neck have install dummy neck time can control dummy neck decrement accurately and easy to operate advantage.
