Description

A kind of lattice scoring tool

Technical field

The utility model relates to scoring tool, and particularly a kind of lattice scoring tool can be used as the instrument use that lattice line in the sheet metal operation, perforate location and other industries are drawn ruling.

Background technology

At present, relate in the metallic plate perforate through regular meeting in the sheet metal operation, the perforate location needs line earlier, cooperates punctuate, line then on the line plane usually with metal board foot and angle square.Because line nib thickness differs, certain error that the line nib can form when metal board foot edge moves is simultaneously because also there is error in the cooperation of human eye and hand; So the lattice that marks line is also inaccurate; Be difficult to satisfy,, the situation of doing over again often occur because the location line is inaccurate in designing requirement.Ruling, efficient is low, of poor quality also brings many troubles to subsequent handling.

So how just can make the lattice line not receive condition and human factor domination? Therefore; The instrument that exploitation is exclusively used in lattice line is for increasing work efficiency, improve the quality of products, simplify the operation operation and enhance productivity significant; And present domestic colleague does not have this type of instrument that is exclusively used in the lattice line to occur as yet, does not see that document has the report of technical article in this respect yet.

Summary of the invention

The purpose of the utility model is exactly for overcoming the deficiency of prior art; To a lattice line difficult problem; A kind of design of scoring tool is provided, adopts a kind of cursor structure scoring tool of innovation, make it the ruling of confirming the drafting position of ruling exactly and can drawing any size.

The utility model is to realize through such technical scheme: a kind of lattice scoring tool, it is characterized in that, and constitute by standard board foot, backboard, angle positioning rule and vernier;

Standard board foot upper surface is processed with chute; Standard board foot end is the lower limit of right angle projective structure; Backboard is a rectangle metallic plate; The metallic plate right panel is provided with axis hole;

The angle positioning rule is a chi plate that has the position sign, and chi plate head end is the upper limit of right angle projective structure; Chi plate head end also be processed with backboard on the corresponding axis hole in axis hole position;

Vernier is a square, comprises crossfoot and perpendicular chi, and crossfoot is vertical each other with perpendicular chi, and the crossfoot back side is processed with feather key, and the chute on feather key and the standard board foot is slidingly matched;

The back side, top of standard board foot is fixed on the backboard Left-Hand Panel, cooperates through axis hole on bearing pin, the angle positioning rule and the axis hole on the backboard, and the angle positioning rule is connected on the backboard right panel; And to make the angle positioning rule be that rotate in the axle center with the bearing pin;

Chute on the standard board foot and the feather key on the crossfoot are slidingly matched, and standard board foot and vernier are movably linked together; Vernier is that track moves up and down with the chute;

When the angle positioning rule was in the start angle position, standard board foot and angle positioning rule were parallel to each other, and two chis distance each other can be the arbitrfary point in the 2-10cm scope, is 0 point with the bearing pin axle center, and the extended line on edge is crossed the bearing pin axle center in the long limit of angle positioning rule.

The beneficial effect of the utility model is: use the lattice scoring tool, need not calculate and can mark required ruling, not only accurate positioning; Eliminated simultaneously because the line error that manual operations exists; So the ruling that marks is accurately consistent, be exclusively used in draw ruling and in given line scope even lattice, it is easy and simple to handle; Operating efficiency, product quality and production efficiency have been improved greatly, creative and promotional value.
