Hole drilling device

Abstract

To provide a drilling device which can prevent deterioration of position accuracy of drilling.SOLUTION: A drilling device (1) includes: an installation base 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 (42s) 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 suctions powder dust in the discharge chamber (43) to collect the powder dust; and an air inflow valve (70) which is connected to the discharge chamber (43) and may switch a state of the drilling device (1) between an inflow state where air flows into the discharge chamber (43) and a blocking state in which the inflow of air into the discharge chamber (43) is blocked.SELECTED DRAWING: Figure 2

Claims

1. A drilling section for drilling holes in the workpiece, A mounting base having a mounting surface for placing the workpiece, and a discharge chamber positioned on the opposite side of the mounting surface from the drilling section, from which dust generated during the drilling process is discharged. A dust collector that sucks up and collects dust from the aforementioned discharge chamber, An air inlet valve connected to the discharge chamber, which can be switched between an inflow state that allows air to flow into the discharge chamber and a blocked state that blocks the inflow of air to the discharge chamber, A pressure sensor for detecting the pressure in the discharge chamber, The system includes a control unit that controls the air inlet valve, The control unit shuts off the air inlet valve when the pressure in the discharge chamber detected by the pressure sensor is higher than a predetermined pressure, and opens the air inlet valve when the pressure in the discharge chamber detected by the pressure sensor is lower than the predetermined pressure. A hole-drilling device characterized by the following features.

2. Equipped with a pressure reducer, The mounting surface of the aforementioned mounting stand is in communication with the vacuum pump, and a suction through-hole for adsorbing a workpiece is formed on the mounting surface. The drilling device according to feature 1.

3. A pressure sensor for detecting the pressure in the discharge chamber, The system includes a control unit that provides notification when the pressure in the discharge chamber detected by the pressure sensor is below a predetermined pressure, The drilling device according to feature 1.

4. The aforementioned drilling unit is a laser irradiator that drills holes in a workpiece by irradiating it with laser light. A drilling device according to any one of claims 1 to 3.
