Abstract

The invention discloses a rotation arm connecting component installing hole machining device. The rotation arm connecting component installing hole machining device comprises a base. The base is provided with a workbench. A positioning base frame is arranged at the top end of the workbench and comprises a vertical plate and a transverse plate which are perpendicular to each other. The transverse plate is fixedly connected with the workbench. A positioning core column is arranged at the middle position of the side face of the vertical plate. Two pressing devices are symmetrically arranged on the two sides of the positioning core column. A moving positioning plate is arranged at the top end of the vertical plate. One end of the moving positioning plate is movably connected with the verticalplate, and the other end of the moving positioning plate is connected with a three-hole drill plate. The base is further provided with a centering clamping device, and the centering clamping device iscomposed of two symmetrically-arranged centering clamping device bodies. The rotation arm connecting component installing hole machining device has the beneficial effects that the rotation arm connecting component installing hole machining device is convenient and fast to operate, labor is saved, the efficiency is improved, meanwhile, the product quality is effectively controlled, and generated economic benefits are obviously improved.

Description

technical field [0001] The invention relates to the technical field of railway vehicle swivel arms, in particular to a mounting hole processing device for a connecting part of a swivel arm, which includes the positioning processing of the mounting holes of anti-drop beam bolts and the mounting holes of special-shaped connecting rods on the swivel arm. Background technique [0002] combine figure 1 and figure 2 As shown, the boom is an important load-carrying part of a railway passenger car, including a pivot arm center plate 100 and a pivot arm rocker 200 and other components. One side of the rotating arm center plate 100 is an annular groove, and the center of the annular groove is provided with a conical boss 300, which is connected with the spring seat of the vehicle frame through a compressed spring during use, and the saddle surface of the rotating arm is installed on the rolling bearing of the wheel set. Its lower end is equipped with an anti-off beam to prevent the...
