Separable positioning device

The invention belongs to the technical field of body-in-white welding, and particularly relates to a separable positioning device which comprises a positioning unit and a positioning foundation, the positioning unit is separably installed on the upper portion of the positioning foundation, a sleeve module and a limiting groove are arranged on the upper portion of the positioning foundation, and the positioning unit comprises an upper positioning part and a lower positioning part. According to the separable positioning device, the mode that the positioning unit is separated from the positioning base is utilized, the position in positioning contact with a body in white is made into a non-standard part, other positions are made into standard parts, and therefore the clamp is quite high in compatibility production capacity, simple in structural design and low in development cost. 本发明属于白车身焊接技术领域，具体是一种可分离式定位装置，包括：定位单元和定位基础，定位单元可分离安装在定位基础上部，定位基础上部设置有套筒模块和限位槽，定位单元包括上定位部和下定位部，上定位部可拆卸安装在下定位部上方，本发明可分离式定位装置利用定位单元和定位基础分离的
