Description

Adjustable skin edge compactor

Technical Field

The utility model belongs to the technical field of the aircraft frock, a covering edge collet with adjustable is related to.

Background

In a certain project, more structural members or systems need to be installed on the outer side of the skin of the barrel section of the fuselage, and when the part of parts are positioned, the assembly deviation is caused because tools such as traditional clamps cannot be used for compressing or clamping the rest of skins, and even the aerodynamic appearance of the surface of the skin is out of tolerance.

SUMMERY OF THE UTILITY MODEL

The utility model provides a covering edge collet with adjustable for the position that the covering edge can't adopt conventional collet compresses tightly, and high-quality operation when realizing aircraft assembly has solved the problem that the covering edge is difficult to the location clamp tightly.

The technology of the utility model is as follows:

an adjustable skin edge compactor comprises a machining piece compactor, a fixing plate, a special bolt and a nut.

The machining workpiece pressing device is of an inverted concave structure, two ends of the inverted concave structure are parallel, one side of the inverted concave structure is provided with two axisymmetric square holes, and the square holes are symmetrical with the center line of the machining workpiece pressing device.

The special bolt is of a threaded structure at two ends, the fixing plate is provided with two threaded holes, and the two threaded holes correspond to the square hole of the machining part pressing device. The special bolt penetrates through the square hole of the machining part pressing device and is connected with the threaded hole of the fixing plate; the upper end of the special bolt is fixed through a gasket and a nut.

The specific implementation process comprises the following steps:

3.1, making primary holes at the edges of the skins according to an adjustable range, wherein the primary holes can be made at the allowance of the skins, and can also be made at normal hole positions so as to make final holes in the subsequent process.

3.2, threading the pressing device through the skin hole and fixing by using a screw.

3.3, the nut on the upper part is screwed down to compress, so that the compressing purpose is achieved.

The utility model has the advantages that:

the utility model discloses accord with the standard requirement and guarantee again fast effectively, this design is innovative on the method, can't realize the utility model a special collet at traditional collet, to the assembly structure requirement at special position, make effectual instrument use at the scene fast, can exert very big effect in each project, the single can shorten nearly 2 hours of cost such as cycle for the company, convenient for material collection, the application is wide, the cost is lower, conveniently duplicates, the facilitate promotion, for accelerating the production development progress, contribution is made to reduce cost. The manufacturing process is novel in design, is rich in creativity and practicability, can be applied to the aircraft assembly industry, can achieve the effects of rapidness and effectiveness as long as related requirements are met, can protect driving and navigation for the production progress, and has a very wide application prospect.

Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

As shown in fig. 1 and 2, an adjustable skin edge compactor comprises a machining part compactor 1, a fixing plate, a special bolt 2 and a nut 3.

Machine add a collet 1 for falling the character cut in bas-relief shape structure, the both ends of falling the character cut in bas-relief shape structure are parallel, the one side of falling the character cut in bas-relief shape structure is equipped with two axisymmetric quad slit, and the quad slit uses the central line symmetry of machine add a collet 1.

The special bolt 2 is of a threaded structure at two ends, the fixing plate is provided with two threaded holes, and the two threaded holes correspond to the square hole of the machining part pressing device 1. A special bolt 2 penetrates through the square hole of the machining part pressing device 1 and is connected with the threaded hole of the fixing plate; the upper end of the special bolt 2 is fixed through a gasket and a nut 3.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
