Problems solved by technology

Traditional electric drills are generally not equipped with tools to measure the drilling depth of the electric drill, so it is difficult to control the drilling depth of the electric drill bit, or for example, when a row of holes with the same spacing needs to be drilled, the traditional electric drill needs to be marked with markings, and the operation is relatively difficult. trouble

Embodiment 1

[0016] Embodiment 1 When in use, the electric drill bit 2 vertically drills into the plane, and the drilling depth of the electric drill is controlled according to the moving distance of the light spot formed by the concentrated light beam on the plane when the electric drill bit 2 drills in.

[0017] see figure 2 , Embodiment 2, an electric drill depth control structure, including an electric drill body 1, an electric drill bit 2 is arranged on the electric drill body 1, a light source 3 capable of emitting a concentrated beam is arranged on the electric drill body 1, and the light source 3 and the The electric drill body 1 is rotatably connected, the light source 3 is provided with a pointer 4, the electric drill body 1 is provided with an indexing plate 5, and the indexing plate 5 is marked with the concentrated light beam emitted by the light source 3 and the The angle of the electric drill bit 2 makes the angle between the concentrated beam and the electric drill bit 2 a...

Embodiment 2

[0018] Embodiment 2 When in use, the angle formed by the concentrated light beam emitted by the light source 3 and the electric drill bit 2 is adjusted to be x, and the electric drill bit 2 is drilled into the plane vertically. Move the distance to control the drilling depth of the electric drill. The moving distance of the light spot on the wall is y, so the drilling depth of the electric drill bit 2 is cotx×y. The length marked on the index plate 5 makes the distance between the electric drill bit 2 and the light spot It can be read directly from the index plate 5, which is more convenient to use.

[0019] The above-mentioned embodiments can all be used for the operation of drilling large round holes, determine a point on the surface to be drilled, and then the electric drill rotates around this point, while ensuring that the electric drill bit 2 is always perpendicular to the surface and the concentrated light beam is always irradiated on the determined point , a large circ...

Abstract

The invention discloses an electric drill depth control structure which comprises an electric drill body. The electric drill body is provided with an electric drill bit and a light source capable of emitting concentrated light. The concentrated light emitted by the light source and the electric drill bit form a certain angle. The light source capable of emitting concentrated light is disposed on the electric drill body, so that drilling depth of the electric drill is controlled according to motion of a spot of the light on a machining surface during use of the electric drill.

Description

technical field [0001] The invention relates to an electric tool, in particular to an electric drill depth control structure. Background technique [0002] The electric drill is a commonly used power tool, and it is also the power tool product with the largest demand. The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and works, and drives the operating device through the transmission mechanism. The gear increases the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. Traditional electric drills are generally not equipped with tools to measure the drilling depth of the electric drill, so it is difficult to control the drilling depth of the electric drill bit. trouble. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a...
