Abstract

A wiring board punching marking tool for a power grid includes a cross framework and four positioning marking components, wherein the cross framework includes a left arm, a right arm, a front arm and a rear arm; the four positioning marking components are mounted on the four arms respectively. The tool has the benefits that the centers of all mounting holes can be confirmed as per positions of the mounting holes in equipment, then the positioning marking components of the punching marking tool are fixed on all the arms of the cross framework, then the punching marking tool is placed on a wiring board, the positioning marking components are beat through a rawhide hammer, so that the center position of a punched hole in the wiring board can be obtained, and position reference points of four holes forming a square when the four hole centers are connected can be obtained through one-time positioned fixing and marking, obtained shapes and position precision of the four holes can be finally guaranteed, the probability of one-time qualified marking for the hole distance of the wiring board can be improved, waste of metal materials can be reduced, and the construction efficiency of secondary construction can be improved.

Description

Technical field

[0001] The invention relates to the technical field of secondary construction of electric power systems, in particular to a hole marking tool for wiring boards for power grids. Background technique

[0002] The wiring board is the intermediate link between the equipment and the transmission line, and its main material is copper or copper-aluminum transition. Because every power transmission line must be connected to the equipment, the wiring board is one of the most common parts of power grid machinery parts, and it is also a part that is installed and replaced frequently. According to the needs of mechanical installation, four holes are generally punched on the wiring board, and the centers of the four holes are connected with a straight line to form a square. The hole distance and shape of the four holes on the wiring board must be strictly corresponding to the equipment. Only when the hole distance and shape of the connecting holes are the same, bolts can be u...
