Positioning pin for positioning during drilling of vehicle body part

Abstract

The utility model relates to a positioning pin for positioning during drilling of a vehicle body part, which is characterized by comprising a positioning section (2) and a consumable section (1) which are connected with each other, and the hardness of the consumable section (1) is smaller than that of the positioning section (2). Compared with the prior art, according to the positioning pin for positioning during drilling of the vehicle body part, the hardness of the consumable section is smaller than that of the positioning section; in the drilling process, the consumable section can be drilled by the drill bit to be abraded, but due to the fact that the hardness of the consumable section is smaller than that of the drill bit, the service life of the drill bit is effectively prolonged. Besides, compared with an arc-shaped groove in the end of a positioning pin in the prior art, the positioning pin for positioning during drilling of the vehicle body part still has a larger supporting area for supporting the vehicle body part even if the end of the positioning pin is abraded, and the positioning pin can rotate slowly in the machining process, so that the service time of the positioning pin can be guaranteed.
