[0002] The JW4G frame is a supporting part of the railway engineering vehicle. It is currently the main product of the workshop. Many of its accessories are space dimensions. The relative size tolerance of each part after welding is required to be ±1mm; there are four front and rear seats, which are located on the inner side of the side beam of the frame. spatial location (such as figure 1 As shown), the size of the workpiece has been finished in place before welding, and the accuracy of the size after welding is guaranteed by the combination. During the combination, there are requirements for both height and horizontal and vertical dimensions, and there is currently no special measuring tool to measure its size. , it is very difficult to assemble. If you do not rely on tooling positioning, it is difficult to achieve the technical requirements of the dimensions after assembly.
