The utility model discloses an auxiliary tool, including sunken board and a plurality of sunken grooves of distribution in its periphery, the material of sunken board is the aluminum alloy, and the shape is the rectangle; the dimension of the sunken groove is designed according to the sunken standard of the L-shaped angle material and comprises a sunken groove length and a sunken groove width, the sunken groove length is larger than the width of a processed surface, the sunken groove width is larger than the thickness of the processed surface, the sunken groove is perpendicular to the rectangular edge, the sunken plate is milled by a numerical control milling machine, and the sharp corner of the sharp edge is rounded. The accuracy of the sinking plate is improved, the consumption of raw materials is saved, and the edge quality and the surface quality are good.

Description

A auxiliary fixtures that is used for L section bar shaping to sink

Technical Field

The utility model belongs to the design of auxiliary fixtures, concretely relates to an auxiliary fixtures that is used for L section bar shaping to sink is applicable to the angle section bar and takes shape when sinking and uses.

Background

The L-shaped angle section part with the sinking type is used as a connecting piece of an airplane body structure and is generally divided into an L-shaped section and an L-shaped plate bending angle section. The method for manufacturing the L-shaped angle part with the subsidence of the airplane belt is generally stamping or manual forming.

The standard sizes of L-shaped angle parts of sheet metal bands are different, when the parts are provided with two or more than two sags and the distance between the sags is less than or equal to 90mm, the parts can not be stamped to be totally sagged, workers are required to manually form the individual sags, and the workers are required to self-manufacture the sagged plates when forming the sags, but the parts are various and large in quantity, and when the sagged plates are manufactured by adopting the traditional method, the deviation causes the ultra-poor sagging of the parts, the surface quality of the parts is poor, the production efficiency is low, and a large amount of waste of raw materials is caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome at present when manual shaping sinks because the less unsatisfactory problem of processing effect who exists of size provides an auxiliary fixtures that is used for L section bar shaping to sink.

The utility model discloses in one aspect, provide an auxiliary fixtures that is used for L section bar shaping to sink for with L section bar processing for have the difference in height two parts, it includes sunken board and distributes at its peripheral a plurality of sunken grooves, the material of sunken board is the aluminum alloy, the shape is the rectangle; the dimension of the sunken groove is designed according to the sunken standard of the L-shaped angle material and comprises a sunken groove length and a sunken groove width, the sunken groove length is larger than the width of a processed surface, the sunken groove width is larger than the thickness of the processed surface, the sunken groove is perpendicular to the rectangular edge, the sunken plate is milled by a numerical control milling machine, and the sharp corner of the sharp edge is rounded.

Advantageously, the tool is also used for inspecting parts.

Advantageously, when the auxiliary tool is used for forming sinking of the L-shaped section, the sinking transition area of the L-shaped section is clamped into the corresponding sinking groove, and the two parts of the L-shaped section are respectively knocked to be tightly attached to the sinking plate through the hammer on the upper side and the lower side of the sinking plate.

Has the advantages that: adopt the utility model is used for L section bar takes shape sunken auxiliary fixtures can alleviate the manual work that takes shape the sunken board of panel beating by a wide margin, has improved the precision of the board that sinks, has practiced thrift the consumption of raw and other materials, and the sunken shaping of conduct L type provides the powerful guarantee, guarantees the part qualification rate more than 95%, and edge quality and surface quality are better.

The features, functions, and advantages that have been discussed can be achieved independently in various examples or may be combined in yet other examples. Further details of the examples can be seen with reference to the following description and the accompanying drawings.

Drawings

The illustrative examples, as well as a preferred mode of use, further objectives, and descriptions thereof, will best be understood by reference to the following detailed description of an example of the present invention when read in conjunction with the accompanying drawings, wherein:

fig. 1 is the structure schematic diagram of the auxiliary tool of the utility model.

Detailed Description

The disclosed examples will be described more fully with reference to the accompanying drawings, in which some (but not all) of the disclosed examples are shown. Indeed, many different examples may be described and should not be construed as limited to the examples set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring to the attached drawing 1, according to the sinking standard of various common L-shaped angle bars, a digital model of a sinking plate of a part is designed, an auxiliary tool comprises the sinking plate 1 and a plurality of sinking grooves 2 distributed on the periphery of the sinking plate 1, and the sinking plate 1 is made of aluminum alloy.

When the auxiliary tool is machined, all sunken digifax are arranged on one aluminum plate, and a plurality of sunken rows are milled on one aluminum plate by using a numerical control milling machine, so that the accuracy of the tool size is ensured. The sharp corners of the sharp edges need to be rounded, so that the parts are prevented from being pressed and scratched during processing.

And (3) during sinking processing, step 1: checking a part appearance template or drawing to determine a part sinking standard;

step 2: finding out the position of the corresponding part according to the sinking position of the part shown by the part shape template, and marking out the sinking position of the part by using a scriber;

and step 3: selecting a sinking plate according to the sinking standard requirement of the part, aligning the position of the sinking plate with the marking line of the marking pin, and then striking the sinking area of the part overlapped with the sinking plate by using a hammer.

The auxiliary tool is not only used for forming sinking of the L-shaped angle section, but also is convenient for checking parts.

The tool is a rigid part, and the size of the tool is designed according to the sinking standard of the part. When the auxiliary tool is used, the auxiliary tool with the corresponding specification is selected according to the sinking standard of the part, and the part is formed.

The sinking standard of the auxiliary tool can be changed according to the part standard, and the auxiliary tool is provided with a plurality of standard sinking grooves 2.

The description of the different advantageous arrangements has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the examples in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Additionally, the different advantageous examples may describe different advantages as compared to other advantageous examples. The example or examples selected are chosen and described in order to best explain the principles of the examples, the practical application, and to enable others of ordinary skill in the art to understand the disclosure for various examples with various modifications as are suited to the particular use contemplated.
