Background
Before the die forging connecting rod is sent into a machine tool for further processing, the R parts at the two ends of the die forging connecting rod are die-forged and formed, so that the die forging connecting rod cannot be clamped when the machine tool is used for processing the die forging connecting rod (see figure 1), the left claw and the right claw of the machine tool can clamp the outer circle of the thin end, but the upper claw and the lower claw cannot be clamped, and an auxiliary tool is added to finish the die forging connecting rod. Besides being incapable of clamping, the center also has the problem of being incapable of supporting. The common G60 connecting rod blank weighs 5360kg, tip holes must be drilled at two ends, the bed tail tip can extend out to tightly prop up the center hole, but the length of the bed head tip extends out to 150mm at maximum, and the depth of the connecting rod blank concave R is 300-500 mm, and the extending amount of the bed head tip is far beyond.
At present, a plate bar is welded at the thin end of a blank, which is equivalent to plugging a part of R part, so that center holes are conveniently punched at two ends like a traditional workpiece, and clamping alignment is completed. However, the welded portion is often a sample area, which interferes with the sample taking, and the thermal welding also has a certain influence on the performance of the sample taking. The turnover process is added when the plate ribs are welded, the process of sawing the plate ribs is added after welding, and the processing process of the connecting rod blank is added, so that time and energy are consumed.
