Description

[0001] Jig Apparatus For Hand Drill [0002]

More particularly, the present invention relates to a jig mechanism for drilling work, which can freely change the position of a hand drill during hole drilling such as repetitive drilling, reaming, tapping, etc., thereby improving the efficiency of the machining operation, The present invention relates to a jig tool for a hand drill which is very convenient to use and portability and can improve the convenience of work.

Drills are widely used in many industries. Especially, the hand drill, which is designed to be held by the worker with one hand, is a power tool that is generally used in a home. Hand drills are used to drill holes or fasten screws in a member. They can also be classified as rechargeable or non-rechargeable.

In the case where various members such as wood, synthetic resin, and aluminum are to be connected to each other, when it is difficult to directly connect with a screw, there are many cases where a small hole is drilled in advance and a screw is screwed in place. At this time, the hole should be drilled in the correct position of the member. A jig means is useful for drilling at predetermined positions of various members having the same specifications. If there is no auxiliary means such as a jig, each member should be measured, marked, and spaced each time, and then drilled. This slows down the operation very slowly, and furthermore, miscalculation of the position or drilling of the hole causes the perpendicularity to the workpiece to be inadequate. The same problem arises when the depth of the hole is fixed. It is also difficult to provide a proper jig when drilling a hole with a certain depth.

As for a drill jig, Korean Patent Application No. 10-2003-0075091 is a prior art example. This document includes a plurality of supports to be clamped to a workpiece to be drilled; A guide bar coupled to both ends of the support portion and extending in the longitudinal direction of the workpiece; A ball bush installed on the guide bar to slide on the guide bar; A mounting plate provided on the ball bush; A shaft mounted on an upper portion of the mounting plate in a vertical direction; A drill holder fitted to the shaft and having a drill mounted on one side thereof; A handle portion for vertically moving the drill holder in the vertical direction; The drill jig for hole drilling according to the present invention is characterized in that, when a plurality of aligned holes are formed in a workpiece, the drill jig according to the present invention has a complicated dictionary There is proposed a drill jig for hole processing which can form a hole by a single operation without any work and can easily form hundreds of holes in a longitudinal direction for a short time.

It is a drill-only device for professionally machining holes and not for general use and not for hand drills.

As a jig for a hand drill, Korean Patent Application No. 10-2012-0024195 has been disclosed. In this technique, a hand drill jig device for supporting a hand drill includes a fixing portion fixed to an object to be processed, And a drill supporting part supported by the rotor of the hand drill. According to the structure, a fixing part fixed to the object to be placed on the ceiling; And a drill supporting part which is supported in a region of the entire area of the fixing part and is supported by a rotator of the hand drill, wherein the fixing part includes a plurality of pawls, the fixing part includes a pawl extending in one direction, The drill supporting portion includes: a support main body portion penetrated by the respective claw portions of the plurality of fixing portions; A pole support portion for supporting between the support main body portion and the pole portion; And a rotor support portion supported by the support body portion between the adjacent pole portions and supporting the rotor of the hand drill.

This device appears to be a dedicated jig for drilling holes in the flange of the H. beam. That is, it is difficult to control the depth of perforation, and it is difficult to use for slabs and plates.
