Abstract

The utility model discloses a projection marking tool, including frame, guide pen and drawing pen, the frame is the U -shaped, and guide pen and drawing pen are installed in the both ends that the frame is relative, and the nib of guide pen is relative with the nib of drawing pen, guide pen and drawing pen are respectively through spout support mounting in frame, on guide pen and drawing pen are fixed in the spout support through pinch -off blades respectively. The beneficial effect of the utility model: projection marking tool with the projection of surplus line in one side that the operator easily observed, effectively avoided causing the part trouble because of errors in observation, the processsing efficiency of components is increased. Projection marking tool operating method is simple, does not need higher operative skill, projection marking tool can adjust or change support and drawing pen, is applicable to the part of all kinds of sizes.

Description

A kind of projection scoring tool

Technical field

This utility model relates to a kind of hand-operated tools, the instrument particularly rule。

Background technology

Along with the development of composite extensive use in aircaft configuration and Composites Molding Techniques, the structure of composite material parts also becomes increasingly complex。Due to Composites Molding Techniques, the surplus line of the composite after molding, generally in the inner side of part, it has not been convenient to on-the-spot blanking operation。

Existing be usually execute-in-place work while observe inner side surplus line, blanking。Owing to observing part medial and lateral frequently, very easily cause operational error, cause part rejection, and working (machining) efficiency is very low。

Summary of the invention

The purpose of this utility model is to provide a kind of safe and reliable, instrument of ruling conveniently and efficiently。

This utility model one projection scoring tool, including framework, guides pen and bow pen, and framework is U-shaped, guides pen to be installed on the two ends that framework is relative with bow pen, and the nib guiding pen is relative with the nib of bow pen。

Described guiding pen and bow pen are installed on framework respectively through chute support。

Described guiding pen and bow pen are fixed on chute support respectively through clamping plate。

Described bow pen includes pen core, spring, baffle plate and handwriting, and pen core is installed in handwriting, and spring is positioned over pen core top, arranges baffle plate between spring and pen core。

Bow pen and guiding pen are all fixed on framework, adjust the relative position guiding pen and bow pen according to demand；Pen is guided to be used for guiding line, it is not necessary to dyestuff (during if desired for labelling, the replaceable guiding pen having dyestuff)；Bow pen is used for the surplus line projection of part side to part opposite side, can change pen core by threaded engagement, and in bow pen, the design of baffle plate and spring can ensure that bow pen passes through a degree of rough surface simultaneously。

The beneficial effect that technical solutions of the utility model are brought:

The side that surplus line projection is easily observed by projection scoring tool operator, effectively prevent because error in observation causes Parts Breakdown；Improve the working (machining) efficiency of part；Projection scoring tool operational approach is simple, it is not necessary to higher operant skill；Projection scoring tool can adjust or change support and bow pen, it is adaptable to the part of needles of various sizes。

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail。

See Fig. 1 to Fig. 4, this utility model one projection scoring tool, including framework 3, guide pen 1 and bow pen 2, framework 3 is U-shaped, guides pen 1 to be installed on the two ends that framework 1 is relative with bow pen 2, and the nib guiding pen 1 is relative with the nib of bow pen 2。Pen 1 and bow pen 2 is guided to be installed on framework 3 respectively through chute support 11。Pen 1 and bow pen 2 is guided to be fixed on chute support 11 with by clamping plate 13 respectively。

Bow pen 1 includes pen core 7, spring 5, baffle plate 6 and handwriting 8, and pen core 7 is installed in handwriting 8, and spring 5 is positioned over pen core 7 top, arranges baffle plate 6 between spring 5 and pen core 7。

Specifically used method:

Use front PLSCONFM part thickness whether more than the adjusting range of framework and bow pen, if greater than the scope of framework and bow pen, then need to change bow pen or framework, otherwise, then can use；Confirm that the surplus line ultimate range to blank limit is whether more than the adjusting range of framework simultaneously, if greater than the adjusting range of framework, then need to remove unnecessary clout or replacing framework, otherwise, then can use。Confirmed can use after, the pen that guides of scoring tool is positioned over the side of existing surplus line, bow pen is positioned over the side that need to rule, and uses and guides the existing surplus line of pen to slide, and the bow pen of opposite side can leave the surplus line of needs at part。
