Description
Technical Field
The invention relates to the technical field of automobile assembly, in particular to a pre-matching adjusting and positioning tool for a front cover of an automobile body and an installation process.
Background
The installation process of the opening and closing piece (door and cover) of the automobile body manufacturing workshop in the automobile manufacturing industry aims to meet the requirements of meeting the man-machine engineering and the assembly precision on the premise of meeting the productivity, and a set of popular process and equipment design is provided; however, the phenomenon that the matching precision meets the requirement after one-time assembly and rework is nearly one hundred percent of the requirement due to poor man-machine engineering generally exists, and the one-time quality qualification rate, the capacity and the traffic report rate are greatly influenced.
The typical problems of the prior art are as follows: after the front cover and the fender are installed, the gap and the surface difference between the front cover and the fender as well as the front door cannot be installed once and then are qualified, the fender harness has a huge body shape and is hung in the air, and the operation of the process of installing the fender is complicated and the working hours exceed the standard; the front cover mounting tool has poor man-machine engineering in the front cover mounting process; the specific reasons are as follows:
1. the front cover hinge is positioned by a tool, stable position precision is provided in the height direction relative to the side wall main positioning hole of the vehicle body, the height position of the front cover after installation is determined, the front door is installed and adjusted without reference to the side wall main positioning hole (the height of the front cover hinge) for matching, the rear part of the front fender is aligned with the rib line of the front door in the height direction, and finally the matching of the front cover and the front fender in the height direction (the gap and the surface difference) is in a problem;
2. the left and right fender panels are installed with a consistent gap (controlled by a gap block) with the left and right front doors, but the front and rear position degrees of the fender panels are accumulated by the matching deviation of the gaps between the rear door and the rear part of the side wall and between the front door and the rear door, so that the front and rear position degrees of the left and right fender panels are inconsistent. The front cover mounting tool is positioned on the vehicle body by two holes on the left fender and the right fender, so that the front cover mounting tool has offset fluctuation on the vehicle body, and the orientation of the front cover after the front cover is mounted is offset. Finally, the reworking is caused because unstable out-of-tolerance often occurs to the matching gaps and the surface differences of the front cover, the fender and the front door;
3. the fender harness is positioned on the vehicle body by adopting a main reference hole at the lower part of the front longitudinal beam, the harness is in a three-dimensional structure with a huge and heavy body, and is driven by a pneumatic hoist hung in the air, so that the operation is time-consuming;
4. the front cover harness is in a fixed tripod form, an operator needs to lift the front cover over the harness and then position the front cover on a positioning pin and a reference of the harness, the harness is taken out after the installation, one person needs to prop the front cover to a certain angle on the side surface, the harness is lifted out by the other person, and the whole man-machine is poor.
