A portable galvanized steel pipe automatic drilling equipment and drilling method thereof

Abstract

The invention relates to a portable automatic drilling device for galvanized steel pipes and a drilling method of the portable automatic drilling device. The portable automatic drilling device comprises a mounting plate, wherein an adjusting fixing device is mounted on the mounting plate; a steel pipe body is clamped and fixed on the adjusting fixing device; a drilling performing device is mountedon the outer side of the lower end of the mounting plate; and two clamping positioning devices are mounted on the drilling performing device and symmetrically positioned on the upper side and the lower side of the drilling performing device. The portable automatic drilling device can solve the following problems in the existing steel-pipe drilling operation process: an electric drill is needed tobe hand-held manually to drill holes in steel pipes; human body posture adjustment according to the position of a hole to be drilled is needed; when a drill bit contacts the surface of a steel pipe,misplacement is liable to happen, thereby affecting the accuracy of a drilling position; rapid vibration of the electric drill during drilling can easily cause the drill bit to snap due to an operation error, so that a potential safety hazard exists; and in addition, the drilling time for a thicker steel pipe is long, so that manually hand-holding the electric drill while maintaining a fixed working posture for a long time is needed and thus the labor intensity is high.

Description

technical field [0001] The invention relates to the technical field of galvanized steel pipe processing, in particular to a portable galvanized steel pipe automatic drilling device and a drilling method thereof. Background technique [0002] Galvanized steel pipes are currently widely used in the transportation of gas and heating. The early laying of gas and heating requires a large number of galvanized steel pipes for connection. The connection between galvanized steel pipes requires the use of sleeves to connect two steel pipes. The galvanized steel pipe is processed. In order to ensure the stability of the butt joint of the steel pipe, it is necessary to drill the surface of the casing, fasten the steel pipe with the help of existing tools through the specified aperture, and then perform sealing treatment. The missing casing needs manual temporary processing, which is an important step in processing the casing when drilling. However, in the existing steel pipe drilling pr...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a portable galvanized steel pipe automatic drilling device and its drilling method, which can solve the existing problems in the existing steel pipe drilling process that the steel pipe needs to be drilled manually with a hand-held electric drill, and manual drilling is required. Adjust the posture of the body according to the position of the drilling hole. When the drill bit touches the surface of the steel pipe, it is easy to dislocate, which affects the accuracy of the drilling position. The rapid vibration of the electric drill during drilling is likely to cause the bit to break due to misoperation, which poses a safety hazard, and the specification is relatively small. It takes a long time to drill thick steel pipes, and manual hand-held electric drills maintain a fixed position for a long time, which is labor-intensive, poor stability and low work efficiency. It has the advantages of low labor intensity, good stability and high work efficiency
