The invention relates to an auxiliary supporting device and method for machining holes in a combined transmission box body. The device is composed of an auxiliary supporting system and a pre-adjusting device. The auxiliary supporting system is mainly composed of a center base and a plurality of supporting rods evenly distributed on the center base, pre-adjusting measuring rings with various diameters are arranged on the pre-adjusting device according to needs, the heights of the pre-adjusting measuring rings are different, and a boss is arranged in the center of the pre-adjusting device and matched with a shaft hole of the center base for positioning. The auxiliary supporting device for machining the holes in the combined transmission box body is simple in structure and high in operability, in the machining process of large thin-wall high-precision box bodies such as the comprehensive transmission box body of an armored vehicle, the rigidity of the box bodies can be effectively improved, and the machining precision and the machining quality of the box bodies of the type can be improved.
Description
technical field [0001] The invention belongs to the technical field of machining, and in particular relates to an auxiliary support device and method for machining holes of a comprehensive transmission box body. Background technique [0002] The integrated transmission box is an important part of the transmission system of the armored vehicle, and its processing quality directly affects the reliability of the transmission system of the armored vehicle, and in severe cases, it will also affect the maneuverability of the entire armored vehicle. The comprehensive transmission box is a large thin-walled aluminum alloy part with a complex structure and high precision requirements, especially for the accuracy of the trunnion holes used to assemble the planetary transmission mechanism, torque converter bracket, etc. The position accuracy of each group of trunnion hole systems is very demanding. high. When processing the trunnion hole system in the existing scheme, a special fixtur...
