Processing method of steering vertical axle seat of 8×8 wheeled armored vehicle

Abstract

The invention relates to a processing method for a steering vertical shaft seat of a wheeled armored vehicle, in particular to a precision processing method for a steering vertical shaft seat of an 8×8 wheeled armored vehicle. Through a special processing machine tool, the method of processing the vertical shaft seat by reverse pulling is adopted, which solves the technical problems such as the high rework probability of the vertical shaft seat of the steering shaft seat and the welding deformation of the shaft seat hole. The processing process is as follows: install the special processing machine tool under the ground level, install the wheeled armored vehicle on the positioning and clamping device of the special processing machine tool, make the boring tool pass through the bottom hole of the vertical shaft seat from bottom to top, and make the boring tool go from Up and down movement completes the machining of the shaft seat hole. In the process of processing, a special measuring device is used to realize the measurement with a tool, and the diameter of the boring tool is adjusted according to the measurement data to complete the machining of the vertical shaft seat. The invention avoids the structural limitation of the 8×8 wheeled infantry fighting vehicle, and completes the machining of the vertical shaft seat from bottom to top on the outside of the vehicle, ensures the position and aperture of the vertical shaft seat, and reduces the rework probability of the vertical shaft seat.

Description

Technical field: [0001] The invention relates to a processing method for a steering vertical shaft seat of a wheeled armored vehicle, in particular to a precision processing method for a steering vertical shaft seat of an 8×8 wheeled armored vehicle. [0002] technical background: [0003] The 8×8 wheeled armored vehicle adopts the rare H-type transmission, which requires accurate position and high precision of the power steering shaft in the steering mechanism. The vertical shaft seat for the steering shaft is fixed on the inner floor of the vehicle. Due to the structural limitations of the 8×8 wheeled infantry fighting vehicle, the usual processing method cannot be realized. At present, it can only be manufactured by welding, which has the following two disadvantages 1. It is not easy to control the position accuracy of the vertical shaft seat, and the rework rate is high; 2. The vertical shaft seat is welded and easily deformed when heated, which increases the friction bet...
