Abstract
A dump truck sub-frame assembly welding die is characterized in that six supporting legs are symmetrically welded on the lower part of a base plate. Two longitudinal beam positioning channel beams are symmetrically welded on the base plate for horizontally positioning the sub-frame left longitudinal beam and the sub-frame right longitudinal beam. Longitudinal beam clamping devices makes the sub-frame left and right longitudinal beams clamped on the base plate. Every crossbeam has positioning and clamping devices. Two trip shaft supports are positioned by positioning spindles and the shaft holes of the two trip shaft supports are ensured to be at the same center line. The sub-frame size, shape and position precision can be guaranteed due to the two longitudinal beams, each crossbeam and two trip shaft supports are all precisely positioned. The operating efficiency of the subsequent installing debugging process is improved. The dump truck using reliability is also improved. The sub-frame assembly welding operating efficiency can also be enhanced. The sub-frame assembly welding man-hour is significantly reduced.
