AI Technical Summary

Technical Problem

Existing drilling devices face the issue of pipe clogging due to dust accumulation, leading to reduced suction force and potential workpiece quality deterioration, necessitating frequent and labor-intensive cleaning.

Method used

A drilling device with a labyrinth-shaped bent passage section in the suction path and a detachable recovery device that allows dust to accumulate, reducing the likelihood of pipe clogging by facilitating easy cleaning and maintenance.

Benefits of technology

The solution effectively reduces the workload of pipe cleaning by minimizing dust adherence to the piping, maintaining efficient dust removal, and ensuring high-quality workpiece production.

Abstract

To provide a drilling device which enables reduction of a workload of pipe cleaning.SOLUTION: A drilling device (1) includes: an installation base (40) having a drill part which performs drilling to a workpiece (W), and a discharge chamber (43) which is disposed at the opposite side of the drill part with respect to an installation surface on which the workpiece (W) is installed and to which powder dust occurring when drilling is performed by the drill part is discharged; a dust collector (20) which collects powder dust of the discharge chamber (43); a pipe (21A) which is connected to the dust collector (20) and forms a suction path (SP1) for suctioning powder dust; and a recovery device (50) which is detachably attached to the pipe (21A) so as to be disposed in the suction path (SP1) and configured so that powder dust is accumulated more easily than in the pipe (21A).SELECTED DRAWING: Figure 1
