Socket shell hole composite drilling device

Abstract

The invention provides a socket shell hole composite drilling device which consists of a pressing screw, a pressing block, a drill jig body, a positioning shaft and a handle. The drill jig body is ofa rectangular frame structure, the center of the drill jig body is provided with a stepped inner hole, the upper side surface, the lower side surface and the right stepped surface of the drill jig body are provided with drilling guide holes, the symmetrical center of the guide holes is provided with a positioning hole, and the positioning hole communicates with the stepped inner hole; the pressingblock is arranged in the stepped hole of the drill jig body, a gap is formed between the appearance of the pressing block and the stepped inner hole of the drill jig body, the pressing block and thedrill jig body slide mutually within a set distance range, the head of the pressing screw is connected with the pressing block, the distance of the pressing block can be adjusted by rotating the screw, the positioning shaft is of a stepped cylindrical structure, a groove is formed in the outer circular surface with the smaller diameter, a cylindrical hole is formed in the outer circular surface with the larger diameter, and the cylindrical handle is pressed into the cylindrical hole in an interference manner. The device meets the requirements of carrying out cylindrical surface drilling and flange surface drilling through one-time positioning compaction, effectively cuts burrs in side hole wall holes, and solves the problem of burr removal after drilling in cross holes.

Description

technical field [0001] The invention relates to a composite drilling tool for socket housing holes used for special electrical connectors, in particular to a composite drilling device for socket housing holes. Background technique [0002] In the structural design of electronic products, cylindrical shell parts are often used, which are usually used in the occasions where two parts are positioned and matched with each other and fixedly connected. When drilling the cylindrical surface of the cylindrical shell and the flange surface of the shell, two methods are usually used: one is to use high-precision equipment to use the center drill point drill for positioning, and then use the drill to drill along the positioning point; the other is Using different drilling devices to process holes on the cylindrical surface and flange holes separately, the work efficiency is very low, and it is not suitable for mass production. Due to different processing procedures and inconsistent po...
