Problems solved by technology

[0002] Usually, when a manual electric drill is used to drill holes on pipelines or other arc surfaces, due to the lack of limited positioning, it is easy to cause the drill bit to slip during the drilling process, which is inconvenient to operate, the position of the drilled hole is deviated, and the drilled hole does not reach the target. to the desired effect
However, drilling holes on fixed tools such as bench drills has poor flexibility and cannot meet the requirements of temporarily adding holes to piping parts of large-scale units.

Abstract

The invention provides a drill hole positioning device which comprises a positioning part, a guiding frame and a guiding cylinder. The positioning part is provided with a concave positioning area matched with the outer surface of a workpiece to the machined. The guiding frame is connected to the positioning part. The guiding cylinder is connected with the guiding frame in the guiding direction in a rectilinear motion mode, and is provided with an inner hole for being connected with an electric drill so that the drill bit of the electric drill can penetrate through the inner hole and extend towards the concave positioning area. The drill hole positioning device can effectively prevent the drill hole deviation caused by the sliding of the hand-operated electric drill in the process of pipeline part drilling, and the precision of a matched hole is improved.

Description

technical field [0001] The invention relates to a positioning device, in particular to a drilling positioning device for a manual electric drill. Background technique [0002] Usually, when a manual electric drill is used to drill holes on pipelines or other arc surfaces, due to the lack of limited positioning, it is easy to cause the drill bit to slip during the drilling process, which is inconvenient to operate, the position of the drilled hole is deviated, and the drilled hole does not reach the target. to the expected effect. However, punching holes on fixed tools such as bench drills has poor flexibility and cannot meet the requirements of temporarily increasing the hole position on the piping parts of large-scale units. Contents of the invention [0003] The object of the present invention is to provide a drilling positioning device, which can effectively prevent slipping when using a manual electric drill to drill holes on pipelines or other arc surfaces, resulting...
