Vehicle body front face precision detection tool

The invention provides a vehicle body front face precision detection tool comprising detection units which are provided with positioning mechanisms which are used for positioning a vehicle body front face, and detection holes; a framework which is used for fixing the detection units and is provided with reference holes which are used for calibrating the fixing positions of the detection units; and scribing pins which are used for detecting the precision requirement of the vehicle body front face and can be matched with the detection holes. According to the vehicle body front face precision detection tool, the vehicle body front face is positioned by the detection units and the framework, and the size and position of the assembling holes of all the parts and components on the vehicle body front face are detected via matching of the scribing pins and the detection holes so that operation is easy, detection time is short and precision detection of the vehicle body front face can be completed by two workers within 120 seconds.
