Abstract

A suspension-type drilling device, comprising a suspension system (2), a control system (1) and a drilling mechanism (3). A bow-shaped arm (207) in the suspension system (2) is connected to a balancing lead screw (306) in the drilling mechanism (3) by means of a horizontal adjusting sliding block (208). The control system (1) is connected to a driving motor of the drilling mechanism (3) by means of a cable (102). For vehicle structures of special vehicles of different models and the positions and sizes of grouped holes around an axle hole, a fixed drilling device is designed to be of a suspension type, a fixed drilling size is designed to be adjustable, and process automation is achieved for manual clamping and manual drill bit rod replacement; in this way, the machining of grouped holes around axle holes of various vehicle types is met, and the universality and the low cost of the device are realized, thereby reducing the labor intensity of personnel and improving the production efficiency.
