Locating pin device and jig suitable for multiple vehicle types

The invention belongs to the field of automobile industry, and discloses a positioning pin device suitable for multiple vehicle types and a jig using a positioning pin. The positioning pins with the cross sections in different shapes do three-dimensional movement according to the set displacement, so that the positioning pins do not need to be replaced when more than two vehicle types are switched on a production line, the rigidity of the positioning pins is guaranteed, interference is avoided when the different vehicle types are switched, and the production efficiency is improved. The device can be applied to assembly of parts needing to be positioned of various vehicle types. 本发明属于汽车工业领域，公开了一种适应多车型的定位销装置及使用该定位销的治具。通过设置多个横截面为不同形状的定位销按设定的位移做三维移动，使得在生产线上切换两种以上车型时不用更换定位销，该设计既保证了定位销的刚度，又能保证在不同车型间切换时不产生干涉，可应用于各类车型需要定位的部件组装。
