Problems solved by technology

[0007] Both of the above two structures have obvious disadvantages: the former has a small operating space and often requires two-handed operation, which is very inconvenient; the latter structure is often locked with the help of tools, and there is a certain distance between the positioning point of the movable block and the drill bit in the axial direction, often Use will cause the spindle to deviate and make noise

Embodiment 1

[0036] Such as Figures 1 to 4 As shown, a bench drill mainly includes: a fuselage 10 , a column 20 , a drill assembly 30 , an adjustment and positioning mechanism 40 and a base 50 . The drill assembly 30 is slidably installed on the fuselage 10 , and the fuselage 10 is slidably installed on the column 20 . The adjustment of the large displacement in the processing process is realized by lifting the fuselage 10 on the column 20 , and the adjustment of the small displacement is realized by lifting the drill assembly 30 on the fuselage 10 .

[0037] The base 50 has a worktable for fixing workpieces for processing, and usually the worktable is parallel to the horizontal plane so as to facilitate the fixing of workpieces. One end of the column 20 is fixed on the machine base 50, and its axis is perpendicular to the worktable.

[0038] One side of the fuselage 10 is provided with a positioning pin 101 , and the positioning pin 101 can be installed on the fuselage 10 along its axi...

Embodiment 2

[0052] The difference from Embodiment 1 is that in this embodiment, the outer end of the rotating shaft 407 is connected with a shrapnel, and the end of the shrapnel abuts against the knob 403 . This method can replace the compression spring 402 and omit the fixing part 401 .

Embodiment 3

[0054] The difference from Embodiment 1 is that in this embodiment, a positioning protrusion that can be matched with a positioning pin is directly formed on the outer wall of the knob, and there is no need to set a positioning ring 405 for positioning.

Abstract

The invention discloses a bench drill. The bench drill comprises a body, a drill bit assembly and an adjusting and positioning mechanism, wherein the adjusting and positioning mechanism can be operated to drive the drill bit assembly to move relative to the body; the adjusting and positioning mechanism comprises a rotating shaft and a knob; a user can operate the rotating shaft to drive the drill bit assembly to move relative to the body; the knob can be movably connected with the rotating shaft in the axial direction of the knob and can also be rotatably connected with the rotating shaft in a unidirectional manner along the axis of the knob; the knob can be positioned at a first axial direction or a second axial direction; when positioned at the first axial position, the knob can be limited in a rotating process; and when positioned at the second axial position, the knob cannot be limited in the rotating process. The bench drill has the beneficial effects that the adjusting precision of the drilling depth can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric tools, and in particular relates to a bench drill. Background technique [0002] At present, drilling machines have been widely used in factories, homes and other places to drill holes of various diameters and depths on various materials. [0003] This type of drilling machine usually includes an adjustment positioning mechanism to control the depth of the drilled hole, which can realize repeated drilling of holes with the same depth. [0004] There are two common adjustment and positioning mechanisms: one is fixed on the handle turntable, and the other is fixed on the spindle sleeve of the drilling machine. [0005] The former is to put a metal ring on the fixed disk of the handle of the drill press. The outer ring of the metal ring is screwed with a locking knob. There is a positioning scale on the metal ring. After positioning, it is locked with the knob, and it rotates with the rotation of t...
