Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, wherein conventional techniques are not described in detail.
Please refer to fig. 2, which is a schematic diagram of the hole guiding device with a semi-closed structure according to the present invention.
The utility model discloses semi-enclosed construction draws hole device from inside to outside by the base member, compression screw, compact heap, drill bushing, locating pin, guide bush, drive nut etc. constitute. The basal body is divided into two parts, wherein one part is positioned in the cavity, and the other part is positioned outside the cavity. The positioning pin is divided into a conical section, a cylindrical section and a threaded section, and the diameter of the tip of the cone is phi 1 and is the same as the inner diameter of a circular ring on the inner surface of a workpiece; the cylindrical section is matched with the guide sleeve by a hole shaft and is in smooth contact with the guide sleeve; the thread section is in common thread fit with the driving nut. The positioning pin and the driving nut are installed in the guide sleeve together, and the guide sleeve is installed in the cavity of the base body in a matched mode through the hole shaft.
