Abstract

The utility model relates to a stereometric supplementary sample board. The utility model adopts the technical scheme that the stereometric supplementary sample board is formed by a substrate, a reinforcing plate and a limiting plate; the substrate is formed by making a working part and a supplementary part into an integrated structure and processing a notch I and a limiting hole on the supplementary part; the reinforcing plate is provided with a notch II; the limiting plate is of a concave structure; the reinforcing plate is inserted into the notch I of the substate; the limiting plate is inserted in the notch II of the reinforcing plate; and both ends of the limiting plate pass through the limiting hole of the substrate. According to the utility model, the weight of the sample board can be reduced, deformation of the sample board is reduced, materials of the sample board are saved, production cost is reduced, the stereometric supplementary sample board is convenient to use and store, and production efficiency is improved.

Description

A kind of solid is added model

Technical field

The utility model relates to a kind of improvement of model, belongs to Machining Technology field.

Background technology

Some External Shapes on aircraft are comparatively complicated, also have the hole of some on part, and these hole number are many, arrange complexity, when these parts of processing, just inconvenience is processed with Digit Control Machine Tool, and need produce with traditional processing mode, normally by model, process.A kind of length is as shown in Figure 1 greater than the thin and long units of 1000mm, when design model, in order to guarantee that model has enough strength and stiffness, need on model, increase the extra section for strengthening.The problem that existing model exists is: 1. extra section and working portion are structure as a whole, and process, therefore with steel plate, model deadweight is larger, the probability that has increased model distortion, even may, because model is out of shape excessive cannot use, affect the part production cycle; 2. size is larger, is not easy to use and deposit; 3. the model of every kind of part is all single-minded fixing structure, and between different models, part is not general, has wasted the manufactured materials of model, has improved production cost.

Summary of the invention

In order to overcome the above problems, the purpose of this utility model is to provide a kind of solid and adds model, alleviates model weight, reduces model distortion, saves sample sheet material, reduces production costs, and conveniently uses and deposits, and enhances productivity.

The technical solution adopted in the utility model is: a kind of solid is added model, substrate, stiffener and limiting plate, consists of; Described substrate is: working portion and add part and make integrative-structure, is provided with gap I and spacing hole adding in part; Described stiffener is provided with gap II; Described limiting plate is concave structure; Stiffener is inserted in the gap I of substrate, and limiting plate is inserted in the gap II of stiffener, and then its two ends are through the spacing hole of substrate.

Above-mentioned solid is added model, and the part of adding on substrate is provided with through hole.

The beneficial effects of the utility model are: while 1. using, substrate, stiffener and limiting plate are fitted together, while not using, preserve respectively, therefore, alleviated the weight of substrate, reduced the probability of model distortion; 2. stiffener and limiting plate can be general, therefore for different thin and long units, as long as change substrate, save sample sheet material, reduced production cost; 3. owing to adopting assembly type, therefore use and deposit conveniently.The utility model is simple in structure, and convenient processing and manufacture is easy to use and deposit, and can save material more than 60%, can improve strength and stiffness more than 70% simultaneously.

The specific embodiment

As shown in Fig. 2-7, a kind of solid is added model, substrate (10), stiffener (20) and limiting plate (30), consists of.

As shown in Figure 4, substrate (10) is: by working portion (11) with add part (12) and make integrative-structure, be provided with gap I (13), spacing hole (14) and the through hole (15) for carrying on (12) adding part.

Stiffener (20) is provided with gap II (21).

Limiting plate (30) is concave structure.

Stiffener (20) is inserted in the gap I (13) of substrate (10), the reinforcement structure that forms a kind of " ten " font, matrix limiting plate (30) is inserted in the gap II (21) of stiffener (20), then its two ends are through the spacing hole (14) of substrate (10), for relatively moving of restricting substrate (10) and stiffener (20).
