Embodiment Construction

[0037] will refer to Figures 1 to 15 Embodiments of the drilling device according to the present invention are described. like figure 1 The drilling device 1 shown is a rotary percussion drill for drilling holes in a workpiece W. As shown in FIG. The housing of the drilling device 1 is formed by the handle part 10 , the motor housing 20 and the gear housing 60 . In the following, the front-back direction is defined such that figure 1 The right side (the top end side of the end drill bit 2 ) is the front side of the drilling device 1 . Further, the up-down direction is defined so that it is perpendicular to the front-back direction. The side where the handle portion 10 extends from the motor housing 20 is the lower side in the up-down direction. The workpiece W is located on the front side of the drilling device 1 . The length of the shell along the front-to-back direction, that is, figure 1 The length along the left and right direction is about 30cm (centimeter) to 40c...

Abstract

A power tool includes: a motor driving an end bit; a housing accommodating the motor; a distance measuring sensor provided at the housing; and a controlling section connected to the distance measuring sensor. The controlling section is configured to exclude an abnormal value from measurement value measured by the distance measuring sensor.

Description

technical field [0001] The present invention relates to a power tool, and more particularly, to a drill capable of measuring the depth of a hole in a workpiece drilled by an end drill. Background technique [0002] Drilling devices are conventionally known, such as percussion drills that drill holes in workpieces by rotating and applying a striking force to an end bit. In order to generate the impact force, the drilling device includes a motor, a cylinder, a piston arranged in the cylinder, an action conversion mechanism that converts the rotational force of the motor into the reciprocating action of the piston, a striker driven by the piston, and an intermediate piece struck by the striker . An end bit is mounted on the end portion of the drilling device. The striker strikes the middle piece so that the strike force is transmitted to the end bit via the middle piece. The rotational force of the motor is transmitted to the end bit so that the end bit rotates around its ax...
