Abstract

(57) [Summary] [Objective] Prevents the workpiece from jumping up when the tool is removed during drilling work on a drilling machine, and when entering and exiting the tool during tapping when tapping. It was invented with a particular emphasis on the safety of people who work by suppressing the rotating action applied to the workpiece. [Structure] (a) A rolling bearing 2 and a sliding bearing 3 are provided on the support body 1 and a rotation stop bar 4 for detachably attaching the support body is detachably provided. (B) A shank 5 and a male screw are formed on the upper part of the rotating shaft 6 of the chuck A, and the rolling bearing 2 is fitted with a washer 8 and a nut 7. (C) A lower adjustment stopper 12, a pressing spring 13, and a washer 8 are set in this order on a slide shaft 11 having a holding portion 10, and are inserted into a slide bearing 3, and further an upper adjustment stopper 14 is attached. .

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applied to a chuck of a drilling machine or a tapping machine used for drilling or tapping work, and prevents splashing of a work by using it, and injuries, blades, or work pieces. It is a drill chuck with a mechanism to prevent the workpiece from flipping up, which can be done safely, accurately and efficiently without damage to the workpiece. When drilling with a conventional drilling machine, when the blade penetrates a workpiece (especially a thin object), when it is pulled out, a rebounding action occurs and a rotational force is applied to the workpiece, so that the hand holding the workpiece There was an irrational point that I put a lot of effort into it, but it was a very dangerous work, because the work piece was often turned around, and injuries and blades were damaged, and defective products were produced.
Tapping and the like were similar when entering and exiting the blade. The present invention has been devised so that people who perform such work can make holes and tap stands accurately, efficiently and particularly safely. The following is a description of the drawings. (A) The vertical length of the support body 1 A rolling bearing 2 and a sliding bearing 3 are provided in a given direction, and a rotation stop bar 4 for detachably attaching the support body to the support of a drilling machine is provided on its side surface.

(B) Put the chuck A having the shank 5 and the rotating shaft 6 with the male screw on the upper part in the rolling bearing 2, and further install the washer 8
Put it in and attach with nut 7.

(C) A slide shaft 11 provided with a holding portion 10 having a set screw 9 at the lower portion, a downward adjustment stopper 12 for adjusting the spring pressure according to the length of the tool C and the thickness of the workpiece D, a pressing spring 13, and a washer. Set in the order of 8, insert into the slide bearing 3, and then install the upper adjustment stopper 14. Since the present invention has the above-mentioned structure, when this is used, the shank 5 is put into the chuck B of the drilling machine, the tool C is attached to the chuck A of the present invention, and the spring is adjusted according to the thickness of the workpiece. Adjust the pressure and fix it with both upper and lower adjustment stoppers, and then apply the rotation stop bar 4 to the support of the drilling machine and work according to the conventional drilling procedure on the drilling machine, so that the push spring 13 works Since the pressing portion 10 strongly presses the work piece when it is pulled out, there is no splashing and the work piece is not rotated, so that the work can be performed accurately and efficiently. In addition, as an example, the following can be done: (a) A V groove is formed on the bottom surface of the pressing portion 10 so that the valley of the sharp edge of the blade fits, and is provided with a guide for a round bar or a pipe.

(B) An abutment guide is provided on the bottom surface of the pressing portion 10.

(C) The sliding shaft mechanism of the present invention is provided outside the rolling bearing of the chuck B of the drilling machine body.
