Abstract

The utility model discloses a multipurpose drilling machine driven by electric-and man-power for processing metal and wood, solving the problems of simple purpose, imbalanced operation, poor quality of drilling hole, and laborious operation. The multipurpose drilling machine driven by electric-and man-power is characterized in that in the premise of maintaining the primary function and the working range of an electric hand drill, a suite of supporting devices to fix the electric hand drill are added, so that the rotation of the electric hand drill is steady, the quality and accuracy of boring is enhanced, and after different woodworking tool grinders are replaced, various processing of the material of wood, the density plate, etc can be carried out. As a machine with multi-function, the electric hand drill can be used separately after separating from the body.

Description

Multipurpose drilling machine driven by electric-and man-power

The utility model is a kind of electric hand drill multiple purpose aeroplane that is applicable to metal and timber processing.

Though existing electric hand drill itself has compact conformation, many advantages such as easy to use, purposes is single, can only be used for holing on metal or other material.And, because the electric hand drill rotating speed is higher, except operator's both hands and health, there is not other support again during boring, therefore, very not steady during work, the hole that gets out is second-rate, and its perpendicularity and positional precision be difficult to guarantee, and operation is effort relatively also.

The purpose of this utility model provides a kind of electric hand drill multiple purpose aeroplane, promptly under the prerequisite that keeps the original function of electric hand drill and the scope of application, set up the fixedly bracing or strutting arrangement of electric hand drill of a cover, form light-duty bench drill, thereby make the electric hand drill stability of rotation, improve the quality and the precision of boring; After changing different cutters, also can carry out multiple processing, realize a tractor serves several purposes materials such as timber or density board.

The utility model is achieved in that it has a support, a guide pillar is installed on support, the body that can adjust up and down is installed on guide pillar, be connected with clamping fixture seat on the body, said clamping fixture seat can slide on body, the anchor clamps that are used for fixing electric hand drill are installed on clamping fixture seat and electric hand drill is installed therein, the clamping fixture seat both sides also are processed with tooth bar; Operating grip and the sector gear that is fixed together is installed in the side of body, and sector gear is meshed with tooth bar on the clamping fixture seat, and the sense-finding switch of control electric hand drill also is installed in the another side of body.During use, move operating grip downwards, sector gear rotates thereupon, and it moves up and down sector gear by the rack drives on the clamping fixture seat, and simultaneously, the tooth bar on the clamping fixture seat is stirred sense-finding switch, and electric hand drill is rotated.

Advantage of the present utility model is, simple in structure, easy to use, promptly kept the original characteristics of electric hand drill, improved the quality and the precision of boring again, drill bit has been taken off, after changing different wood cutters, also can carry out multiple processing to materials such as timber or density board, can groove milling on timber or density board, deburring, clip, chamfered edge, beat square hole etc., a tractor serves several purposes.Electric hand drill itself with also can use separately after body separates.
