A portable three-hole drilling machine

Abstract

The invention discloses a portable three-hole drilling machine. The portable three-hole drilling machine comprises a triangular fixing frame. All corners of the fixing frames are perpendicularly fixedto one ends of fixing rods separately. The other end of each fixing rod is fixedly provided with a suction cup and sleeved with a limiting ring fixedly connected with the fixing rod. The middle of each fixing rod is sleeved with a sleeve slidably connected with the fixing rod. A spring connected to the outer wall of each fixing rod in a sleeving mode is arranged between the corresponding sleeve and the corresponding limiting ring. A fixing plate corresponding to the fixing frame is fixed between the sleeves and is triangular. Three sliding grooves are arrayed at the central position of the fixing plate. Sliding blocks slidably connected with the sliding grooves are arranged in the sliding grooves. Baffles which are attached to the fixing plate are fixed to the upper end and the lower endof each sliding block correspondingly. A fixing block is fixed to the baffle on one side of each sliding block so that the drilling machine can be carried conveniently. The drilling machine is designed to be triangular according to plates where three holes need to be drilled at equal intervals, so that it is ensured that the distances between the holes are the same, the holes to be drilled can beadjusted conveniently, time and labor are saved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a portable three-hole drilling machine. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Generally, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. When processing the triangular fixed plate of parts, it is often necessary to use a drilling machine to open holes. To open three equilateral triangular drilling holes on the plate, it is very troublesome to open multiple sets of such drilling holes, and it is necessary to constantly adjust the position of the drill bit. And repeatedly measuring whether the distance between the drilled holes is an equilateral triangle can be said to be cumbersome, complicated, time-consuming and laborious. The existing drilling machines are usually single-bit drilling machines, which are not suitabl...

When processing the triangular fixed plate of parts, it is often necessary to use a drilling machine to open holes. To open three equilateral triangular drilling holes on the plate, it is very troublesome to open multiple sets of such drilling holes, and it is necessary to constantly adjust the position of the drill bit. And repeatedly measuring whether the distance between the drilled holes is an equilateral triangle can be said to be cumbersome, complicated, time-consuming and laborious. The existing drilling machines are usually single-bit drilling machines, which are not suitable for this type of drilling, and the existing drilling machines are large in size and not suitable for drilling. It is convenient to carry and move for drilling work, so it is necessary to invent a portable drilling machine to drill holes for this group of three equilateral triangular drilling holes
