Description

A metal caliper hole plotter

technical field

The invention relates to the technical field of a caliper hole drawing device, in particular to a caliper hole drawing device for a small metal plate.

Background technique

At present, it is often necessary to draw a line to locate the screw holes during the maintenance of the power system. The distance between the screw holes has very strict requirements on the size, and a slight deviation in the size may cause the screw to not be able to be inserted later. Manually drawing lines to locate screw holes is not only difficult and imprecise, but also inconvenient and requires many processes. The construction work with a large amount of engineering is in the place where the screw holes need to be connected. If the hole distance is not suitable, it will not only consume a lot of time for secondary processing, but also damage the material itself. Electric workers often use a steel tape measure as the main tool to draw the screw hole distance of the high-voltage wire lead plate. The tape measure drawing process is cumbersome, time-consuming and labor-intensive, and cannot guarantee the quality of the project.

Contents of the invention

In order to overcome the shortcomings of the prior art, the present invention proposes a small metal surface caliper hole drawing device, which is characterized in that it includes a ruler (1), a square A (2) and a square B (4), and the ruler ( 1) It is in the shape of a long strip, and the shapes of square A (2) and square B (4) are T-shaped, and the square A (2) and square B (4) are respectively equipped with positioning knob A (3) and positioning knob B (5), there is a groove (6) in the middle of square A (2) and square B (4), the ruler (1) is embedded in the groove (6) between square A (2) and square B (4), The square A (2) and the square B (4) can slide relative to the straightedge (1) along the two edges of the straightedge (1).

The cross section of the groove (6) is trapezoidal, and that of the ruler (1) is also trapezoidal.

The cross-sectional shapes of the square A (2) and the square B (4) are both Ω-shaped.

A scale is set on one side of the ruler (1), and scales are set on both edges of the T-head of the square A (2) and the square B (4) and the gap of Ω.

The beneficial effects of the present invention are: its structure is simple, easy to use and low in cost, and it is mainly used for drawing and positioning the screw holes of the high-voltage lead wiring board. It is convenient to drill and perforate the wiring board, improve work efficiency and improve project quality.
