Description

Marking tool for plate-shaped parts

Technical Field

The application relates to an aviation manufacturing technology, in particular to a marking tool for assembling plate-shaped parts.

Background

The wing of the airplane is a main bearing part of the airplane, the wing rib is the most important component of the wing, and the assembly precision of the wing rib and the wall plate directly influences the service and safety of the airplane. At present, guide holes connected with wall plates on the wing ribs of airplane with partial models are manufactured by numerical control of a machine tool. However, the limitation of a large number of types of airplanes due to the special structure of the wing rib appearance exists, the guide holes for connecting the wing ribs and the wing wall plates can be arranged only by manual marking of workers, and particularly for some large-sized airplanes, the total number of holes for connecting the wing ribs and the wing wall plates of the airplanes is very large, and the number of manufactured holes is very large. The traditional marking off mode relies on the workman to use the steel plate chi to get completely and gets, and the marking off process relies on workman's manual operation completely, and not only marking off efficiency is very low, and the precision is difficult for guaranteeing. Therefore, a marking tool is needed to simplify the process of marking and making holes on the rib edge strip, which not only can effectively improve the efficiency of marking and making holes, but also can effectively improve the hole making precision of the rib edge strip.

Disclosure of Invention

In order to improve the precision of a large amount of manual rulings of current aircraft wing rib and wallboard connection hole site, the utility model aims to provide a marking tool of plate-like part.

The utility model provides a marking tool of platelike part, its characterized in that, this marking tool contains marking off board and limiting plate, the marking off board be a square flat structure, four sides of marking off board are for drawing a line the benchmark, the limiting plate be a square plate structure that is less than the marking off board, the limiting plate setting forms boss structure at the upper surface middle part of marking off board, the side of limiting plate is parallel with the side of marking off board, the side of limiting plate is for fixing a position the benchmark, each side of limiting plate and the distance between the corresponding side of marking off board form one and draw a line standard distance.

The marking tool comprises four marking standard distances, and the four sides of the limiting plate respectively form one marking standard distance with the corresponding side of the marking plate.

When the plate-shaped part marking device is used, one marking standard distance is selected according to the marking requirements of the plate-shaped part, the lower surface of the marking plate of the marking tool is attached to the upper surface of the plate-shaped part, the positioning reference edge of the marking tool corresponding to the marking standard distance is attached to the side edge of the plate-shaped part, and then the plate-shaped part is marked along the marking reference edge.

The method has the advantages that the four common marking standard distances are arranged on one marking tool, different marking requirements of the plate-shaped part on a production site can be met, and the positioning reference and the marking reference corresponding to the marking standard distances can be selected at will according to the marking requirements of the plate-shaped part. The scribing tool has the advantages of high scribing efficiency, simple structure and convenience in use.

The present application is described in further detail below with reference to the accompanying drawings of embodiments.

Detailed Description

Refer to the accompanying drawing, plate part's marking tool of this application contains marking off board 1 and limiting plate 2, marking off board 1 be a square flat structure, four sides of marking off board 1 are for drawing a line benchmark 3, limiting plate 2 be a square plate structure that is less than the marking off board, limiting plate 2 sets up at the upper surface middle part of marking off board 1, forms the boss structure, the side of limiting plate 2 is parallel with marking off board 1's side, limiting plate 2's side is

location benchmark

4, 3 location benchmarks of also drawing a line benchmark 4 are parallel relation, each side of limiting plate 2 and the distance between the marking off board 1 corresponds the side form one and draw a line standard distance.

In the embodiment, the marking tool comprises A, B, C, D four standard distances, and a standard distance is formed between each of the four sides of the limiting plate 2 and the corresponding side of the marking plate 1. These four gauge distances may cover the standard distance requirements for scoring commonly used for aircraft ribs. In the implementation, the side edge of the scribing board is preferably chamfered.

In the embodiment, a marking tool is selected to mark the hole position of one edge strip 5 on a certain wing rib. The rim 6 is a plate-like structure.

The method comprises the following steps:

the upper surface of the scribing tool scribing board 2 is reversely attached to the upper surface of the edge strip 5, the positioning reference edge 4 of the scribing tool corresponding to the scribing standard distance is selected to be attached to the reference side edge 6 of the edge strip 5, and then the upper surface of the edge strip 5 is scribed 7 along the scribing reference edge 3.

(1) Draw a line with a margin A

And selecting a scribing reference 3 with a scribing standard distance of 'A' and a positioning reference 4 on the scribing tool, wherein the positioning reference 4 is attached to the edge 6 of the flange strip, and scribing 7 on the surface of the flange strip along the scribing reference 3, as shown in FIG. 4.

(2) And drawing a line with the edge distance B.

And selecting a scribing reference 3 with a scribing standard distance of 'B' and a positioning reference 4 on the scribing tool, wherein the positioning reference 4 is attached to the edge 6 of the flange strip, and scribing 7 on the surface of the flange strip along the scribing reference 3, as shown in FIG. 5.

(3) And drawing a line with the edge distance of C.

And selecting a scribing reference 3 and a positioning reference 4 with a scribing standard distance of 'C' on the scribing tool, wherein the positioning reference 4 is attached to the edge 6 of the flange strip, and scribing 7 on the surface of the flange strip along the scribing reference 3, as shown in FIG. 6.

Through the work, the influence of human errors on hole site precision is reduced, the assembly quality of the wing rib and the wall plate is effectively improved, and the quality and the reliability of the airplane are further improved.
