The invention provides an automobile frame balance shaft assembly assembling hole location sample frame. The assembling hole location sample frame comprises a rigid rectangular framework formed by four rigid support rods and locating pins, and locating holes are formed in the four corners of the rigid rectangular framework; the spacing distance between the locating holes is matched with that of assembling holes of a balance shaft assembly; the locating pins are arranged in the locating holes, each locating pin is a step cylinder with a hexagon bolt head, the diameter of small steps of the locating pins is matched with that of the assembling holes of the balance shaft assembly, and the diameter of big steps of the locating pins is matched with that of the locating holes formed in the rigid rectangular framework. The automobile frame balance shaft assembly assembling hole location sample frame and the frame assembly assembling method have the advantages that precise locating is conducted on the assembling holes of the balance shaft assembly by adopting the automobile frame balance shaft assembly assembling hole location sample frame, and frame assembly assembling is completed as the criterion, so that the assembling efficiency and the assembling quality of a whole automobile are effectively improved.
Description
field of invention [0001] The invention relates to the assembly technology of the automobile frame assembly, in particular to an assembly hole position sample frame of the balance shaft assembly of the automobile frame and an assembly method of the automobile frame. Background technique [0002] At present, the quality control of the assembly of the vehicle frame assembly in the prior art generally controls the outer width of the vehicle frame assembly (that is, the width of the outer belly of the left and right longitudinal beams of the vehicle frame), that is, the outer width of the vehicle frame assembly is used as the The fixed datum of the left and right longitudinal beams of the frame. When the outer width of the vehicle frame assembly meets the quality control requirements, the left and right longitudinal beams of the vehicle frame are fixedly connected together by installing the balance shaft beam assembly and other parts, thereby forming the vehicle frame assembly. ...
