Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drill device with a brush that is effective in removing chips.

[Prior Art] When drilling a hole using a drill, chips are generated and accumulate around the bottom and top surface of the hole. It was customary to remove such chips by blowing them off with air after or during the drilling process.

[Problems that the invention aims to solve] Removal of chips using air often requires stopping the rotation of the drill, and there are also problems such as chips being scattered over a wide area around the drill. It was hot. Furthermore, when threading is performed, the bottom of the hole must be particularly carefully cleaned, since chips remaining at the bottom of the hole may damage the tap screw tool.

[Means for Solving the Problems] The brush-equipped drill device according to the present invention is constructed by directly attaching a mounting base on which a brush is installed to a drill tool using a set screw.

[Function] In the device of the present invention, the brush rotates together with the rotation of the drill, so the brush cleans the upper surface of the drilled hole while rotating, and generates a swirling airflow, which cleans the area as the drill is pulled up. Blow away the chips from around the hole.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.
In the figure, 1 is a drill chuck, 2 is a drill tool attached to the drill chuck 1, 3 is a mounting base provided with an insertion hole 4 for the drill tool 2, 5 is a set screw for fixing the mounting base 3 to the drill tool 2, 6
is a brush installed on the mounting base 3, and the drill tool 2
is set up around. 7 is a hole drilled in the workpiece 8. The material and shape of the brush 6 are selected to be soft so as not to damage the surface of the workpiece 8.

Next, when drilling with this drill device, the tip of the brush 6 is adjusted so that it finally contacts the upper surface of the workpiece 8 in a somewhat bent manner depending on the depth of the hole 7 to be drilled. Then, the mounting base 3 is fixed to the drill tool 2 with the setscrew 5. Next, the drill tool 2 is rotated to drill a predetermined hole.
At this time, the brush 6 also rotates around the drill tool 2, so the chips discharged along the groove of the drill tool 2 remain around the top surface of the hole 7, but reach the predetermined machining depth. Then, it is cleaned by the rotating brush 6. Further, after the machining is completed, if the drill tool 2 is pulled up while rotating, the chips that fall around the hole 7 are removed by the swirling airflow generated by the rotating brush 6.
Therefore, no chips remain around the bottom or top of the machined hole and are removed cleanly.

[Effects of the invention] As described above, according to the invention, the mounting base on which the brush is installed is attached around the drill tool so that it rotates together with the drill tool. The airflow and cleaning action prevent chips from remaining around the bottom and top of the drilled hole, and there is no need to stop the rotation of the drill tool each time.
