Description

Anodic oxidation anchor clamps for aluminium part

Technical Field

The utility model belongs to the technical field of aviation part manufacturing, and particularly relates to an anodic oxidation clamp for an aluminum part.

Background

The jig plays an important role in conducting power during the anodic oxidation process, and for the jig for aluminum oxidation, not only is good conductivity required, but also the contact area (ideally point contact) between the part and the jig is reduced as much as possible, and more importantly, the jig should have good elasticity to firmly clamp the part, because an oxide film is rapidly generated on the surface of the part during oxidation, if the contact point is changed due to the unclamping between the jig and the part, the conductivity is affected, and the defects such as no oxidation, poor quality of the oxide film and the like are caused.

The clamping piece of the currently common aluminum part anodizing clamp is mostly made of an aluminum alloy material, but the aluminum alloy clamping piece is poor in elasticity, not easy to clamp and fasten and easy to break, and an alkali corrosion is needed before clamping every time to remove a surface oxide film.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides an anodic oxidation clamp for an aluminum part.

The technical scheme of the utility model is as follows:

an anodic oxidation fixture for aluminum parts comprises a hollow fixture main shaft, wherein the upper end of the fixture main shaft is bent, a thin copper sheet is lined at the bent part of the upper end of the fixture main shaft, and a plurality of clamping sheets are arranged on two sides of the fixture main shaft in a layered mode along the axial direction.

Preferably, the length of the jig main shaft and the number of the clamp pieces are determined according to the size and the number of the parts, and the width of the clamp pieces is determined according to the size and the weight of the parts.

Preferably, both ends of the clamping piece are sharp-angled.

Preferably, the middle part of the clamping piece is riveted on the clamp main shaft through an aluminum rivet, and the thin copper piece is riveted at the bent part at the upper end of the clamp main shaft through the aluminum rivet.

in the figure: the device comprises a thin copper sheet 1, an aluminum rivet 2, a clamp main shaft 3 and a clamping sheet 4.

Detailed Description

The present invention will be further described with reference to the following examples, however, the scope of the present invention is not limited to the following examples.

Example 1: the anodic oxidation fixture for the aluminum part comprises a hollow fixture main shaft 3, wherein the upper end of the fixture main shaft 3 is bent, a thin copper sheet 1 is lined at the bent part of the upper end of the fixture main shaft 3, and a plurality of clamping sheets 4 are arranged on two sides of the fixture main shaft 3 in a layered mode along the axial direction.

Preferably, the length of the jig main shaft 3 and the number of the clamp pieces 4 are determined according to the size and the number of the parts, and the width of the clamp pieces 4 is determined according to the size and the weight of the parts.

Preferably, the two ends of the clamping piece 4 are in a sharp angle shape, so that the contact area with the part can be reduced.

Preferably, the middle part of the clamping sheet 4 is riveted on the clamp main shaft 3 through an aluminum rivet 2, and the thin copper sheet 1 is riveted at the bent part at the upper end of the clamp main shaft 3 through the aluminum rivet 2.

Preferably, the grip piece 4 is a titanium alloy piece.

Preferably, the fixture main shaft 3 is made of hard aluminum.

The preparation and use processes of the utility model are as follows:

firstly, a main shaft 3 of the clamp is cut, the clamping quantity is determined according to the size of a part, in the embodiment, a sparse clamp suitable for a large part can select a single side of 10 clamping pieces 4, a dense clamp suitable for a small part can select a single side of 20 clamping pieces 4, and the width of the clamping pieces 4 is determined according to the size and the weight of the part, so that sufficient elasticity and clamping force are ensured, good contact is ensured, and the part is prevented from being burnt or falling.

And secondly, drilling two small holes at the contact part of the clamping piece 4 and the clamp main shaft 3, and riveting one side of the clamping piece by using an aluminum rivet 2.

And thirdly, bending the upper end of the clamp main shaft 3, which is contacted with the conductive rod, lining a thin copper sheet 1, and riveting by using an aluminum rivet 2.

And fourthly, when the clamp is used, the clamping piece 4 is bent according to the size of the part, the part is clamped firmly and is not damaged, and attention is paid to bending the clamping piece 4, so that the clamping piece cannot be pulled forcefully excessively, otherwise, a riveted part is easy to damage, and the service life of the clamp is influenced. If the aluminum rivet 2 is slightly loosened after being used for a period of time, the aluminum rivet 2 can be knocked and then riveted tightly.

The use of the clamp is characterized in that the correct clamping position (non-decorative surface) is adopted, air is prevented from being trapped, parts are prevented from being overlapped, the parts are prevented from being deformed or loosened, and the plate and common parts are clamped by different clamps to control different time and ensure quality.

Sixthly, the main shaft 3 of the clamp is made of hard aluminum material, and the clamp is washed clean after use so as to avoid corrosion of bath solution, and water is preferably dripped when the clamp is not used so as to avoid galvanic corrosion with the clamping sheet 4.

Seventhly, manufacturing according to the requirements of the tool clamp drawing;

eighthly, after the tool clamp is manufactured, testing the tool clamp, and if necessary, improving the tool clamp;

and ninthly, manufacturing the fixture diagram drawn according to the main shape and size.
