Background
On an automobile production line, if a certain part size is out of tolerance, assembly difficulty can influence production line beats and even cause full line production stoppage. Therefore, the quality control of each part is required, and the most effective tool for rapidly and accurately judging whether the size, shape and position of the part are qualified or not is the gauge.
The automobile checking fixture can be divided into an assembly checking fixture and a single piece checking fixture according to the state of the part. The assembly gauge can be used for checking the size, the characteristics and the position characteristics of more than two parts after being combined. In practical development, we often add a single piece of alignment hole/face to the assembly fixture to enable positioning detection of the single piece on the assembly fixture. Therefore, on one hand, the development of part of single-piece inspection tools can be reduced, on the other hand, the assembly welding can be facilitated, the size state of the sub-level parts can be quickly detected and known, and particularly in epidemic situation period, the number of times for the sub-level parts to be visited by a distribution provider can be reduced.
In the current practical inspection tool development, the positioning points are usually fastened by self-tapping screws, and single inspection tools are often developed, so that the state of the single inspection tool is confirmed by the single inspection tool.
As shown in fig. 1, fig. 1 is a schematic structural diagram of another checking fixture in the prior art, the checking fixture adopts a positioning pin 3' of a cross fork, and the positioning pin is lifted up by pushing upwards to leave one positioning groove 11' of a simulation block 1', and falls down after rotating by 90 degrees to fall into a positioning groove of another different height, so that the lifting of the reference point is realized, but the positioning groove needs to be machined on the simulation block of the checking fixture body, the machining precision requirements of the two grooves are high, the whole occupied space is large, the manufacturing cost is high, and the application is less.
How to overcome the defects is a technical problem to be solved by the person skilled in the art.
