Description

Technical Field

[0001] The utility model belongs to the technical field of jigs, and particularly relates to a jig for an aircraft cabin door lock seat. Background Art

[0002] The titanium alloy lock seat is a part of the aircraft cabin door. At present, a general flat-jaw vice is used for clamping during production and processing. The material of the lock seat is titanium alloy, which has a high hardness. During processing, the cutting force is large, and its fixation requires high stability. However, the reliability of the parts during the clamping process using a general flat-jaw vice is poor, and the clamping cannot be positioned, completely relying on the technical level and ability of workers. Therefore, defective products are often produced, increasing the scrap cost and being unfavorable for batch processing. Content of the Utility Model

[0003] The purpose of the utility model is to provide a jig for an aircraft cabin door lock seat with high clamping stability, accurate positioning effect, and simple clamping operation, so as to solve the problems raised in the above background art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A jig for an aircraft cabin door lock seat, including a tooling main body, the tooling main body includes an installation platform, a fixed punch, and a clamping mechanism. The fixed punch is fixedly connected to the upper surface of the installation platform. The clamping mechanism is fixedly connected to both sides of the fixed punch. The clamping mechanism includes side bosses and screws connected to the side bosses. The two side bosses are arranged in parallel, the axes of the screws are arranged in parallel, and the axis of the screw is perpendicular to the side surface of the fixed punch close to the side boss. The installation platform provides support for the entire jig. The outer profile surface of the fixed punch matches the inner hole of the aircraft cabin door lock seat. The fixed punch is used for fixing the aircraft cabin door lock seat. The aircraft cabin door lock seat is sleeved on the fixed punch. The clamping mechanism cooperates with the fixed punch to fasten the aircraft cabin door lock seat. The screw is threadedly connected to the side boss, and the side boss provides support for the screw. The screw can adjust the tightening force on the aircraft cabin door lock seat by screwing. The axis of the screw is perpendicular to the side surface of the fixed boss, which enables the tightening force of the screw to be better transmitted to the aircraft cabin door lock seat, thereby achieving the best tightening effect.

[0006] Further, 4 bases are fixedly connected to the bottom of the tooling main body, and the bases are respectively arranged on both sides of the fixed punch. The function of the base is to level the installation platform to prevent the entire jig from being inclined and fixed due to insufficient flatness of the bottom surface of the installation platform. The 4 bases are symmetrically arranged to make the force evenly distributed.

[0007] Further, the base is composed of pull studs. It is simple to install and easy to replace.

[0008] Further, the clamping mechanism further includes a pin, the pin is connected to the fixed punch, and the axis of the pin is parallel to the axis of the screw. The pin is used for further fastening the aircraft cabin door lock seat.

[0009] Further, the side boss and the tooling body are integrally formed. The integral structure enables the side boss to provide a more stable support for the screw and the pin, making the clamping stability of the fixture better.

[0010] Further, the fixed punch and the tooling body are detachably connected. The fixed punch is replaceable, enabling the fixture to replace fixed punches of different models and shapes, so that the fixture can clamp and process a variety of parts, increasing the adaptability of the fixture.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] A fixed punch is provided on the installation platform for sleeving and fixing the aircraft cabin door lock seat, and the clamping mechanism is arranged opposite and parallel to the side of the fixed punch for fastening the installation platform. Screws and pins are used to fasten the aircraft cabin door lock seat respectively, making the fastening and positioning of the fixture more stable. At the same time, this clamping method solves the problem that the aircraft cabin door lock seat cannot be stably fixed through the traditional fixing form due to the lack of an effective pressing structure. Compared with the traditional fixing form of pressing with a pressing strip, the structure of this fixture is simple, and the operation process is simple and convenient, effectively improving the clamping stability and clamping efficiency.
