Problems solved by technology

During the adjustment process, the reliability of manually adjusting the verticality of the screw rod is poor. When using a square to adjust, the square will easily cause depressions on the surface of the adhesive and affect the flatness of the cured adhesive surface. In addition, this method is time-consuming and inefficient. product assembly cycle

Embodiment Construction

[0024] This part is the embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.

[0025] A device for improving the verticality of pre-embedded screws according to the present invention includes a pressing part 1 and a bushing 2. The pressing part 1 is a structure that matches the plane shape of the area to be processed with adhesive. The pressing part 1 is provided with There are the same number of mounting holes as the embedded screws, the number of bushings 2 is the same as the number of mounting holes, the outer diameter of the bushing 2 matches the outer diameter of the mounting hole, and the inner diameter of the bushing 2 matches the diameter of the screw shaft of the embedded screw.

[0026] Wherein, the mounting hole of the pressing part 1 has an internal thread, the bushing 2 has an external thread, and the internal thread of the pressing part 1 matches the external thread of the bushing 2 . Connec...

Abstract

The invention belongs to the technical field of mechanical processing, and discloses a device and a method for improving the perpendicularity of a pre-embedded screw. The device comprises a compression element and bushings, wherein the compression element is of a structure matched with the appearance of a plane of an adhesive area filled by a part which needs to be processed; the compression element is provided with installation holes which have the same amount with pre-embedded screws, the amount of the bushing is the same with the amount of the installation holes; the external diameter of each bushing is matched with the external diameter of each installation hole; and the internal diameter of each bushing is matched with the diameter of a screw rod of each pre-embedded screw. By use ofthe device, the defects that in an airplane radome or composite material manufacture element assembling process, the screw rod of the pre-embedded fastening screw and the like have poor perpendicularity, is unstable and has low efficiency in an area where adhesive is poured can be effectively eliminated, multi-time reworking is avoided, so that production cost is lowered, and a good quality benefit and economic benefit can be obtained.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a device and method for pre-embedding screws in an adhesive, in particular to a device and method for improving the verticality of pre-embedded screws. Background technique [0002] In the machine-added assembly process of aircraft radome or composite material parts, a large number of screws and other connectors or fasteners are used, and there are scenarios where the screws are embedded in the adhesive for installation. Specifically, the adhesive is filled around the screw installation area, and the screw is placed in the adhesive after the screw is turned upside down. After the adhesive is cured, the corresponding washer and nut are installed on the screw rod; and the screw is mainly installed. In the annular groove of a part, the adhesive is also filled in the groove. [0003] At present, the method adopted is to place the undercut screw in the area where the adhe...
