Abstract

The invention provides a drilling device for workpieces with special-shaped structures. The drilling device comprises a positioning shaft and a drilling template; the positioning shaft and the drilling template designed to match with the workpieces with the special-shaped structures to be machined; a shaft sleeve sleeves the positioning shaft; and an L-shaped right-angled plate connected with theshaft sleeve is contacted with the drilling template in parallel for positioning and clamping from two angles and multiple dimensions of the drilling template surface and the positioning axis. The drilling device is simple, novel and compact in structure and accurate in positioning, and guarantees the size precision of each hole of the workpieces.

Description

technical field [0001] The invention belongs to the field of drilling jigs, in particular to a drilling device for workpieces with special-shaped structures. Background technique [0002] The double-rod DC electric switch machine is used in railway signal products to change the opening direction of the switch, lock the switch switch rail, and respond to the position status of the switch rail. A special-shaped structure workpiece needs to be processed with three M8 threaded holes according to its assembly requirements. and side M4 holes. Its structure is as Figure 8 , Figure 9 and Figure 10 As shown, it includes an L-shaped right-angle plate, and the shaft sleeve is vertically arranged on the L-shaped right-angle plate. Due to its special-shaped structure, it is difficult to guarantee the position of the drilling positioning fixture on the market, and it is not easy to guarantee the size of the direct drilling, and there are easy dimensional deviations between multiple ...
