Description

Technical Field

[0001] The present invention belongs to the technical field of machining, and relates to a liftable universal riveting supplementing tooling adaptable to different types of cabin doors. Background Art

[0002] Aircraft cabin doors are typical movable components on an aircraft, used to provide access for personnel, cargo, and equipment to various areas of the cabin. Generally, 6 cabin doors of three types, namely boarding doors (front and rear boarding doors), service doors (front and rear service doors), and cargo doors (front and rear cargo doors), need to be installed on the whole aircraft. During the assembly and manufacturing process of aircraft cabin doors, after riveting the main structural areas, a certain number of fasteners need to be supplemented and installed, that is, the riveting supplementing work. The riveting supplementing work of cabin door products needs to be carried out on a clamping tooling. Since the outer shape curvatures, lengths, and widths of the above-mentioned cabin door products are different (even for the same type of cabin door, for example, the product curvatures, lengths, and widths of the front and rear boarding doors are not exactly the same), currently, aircraft manufacturing workshops mainly adopt the following method: design a set of special riveting supplementing tooling for each cabin door to ensure the clamping and positioning of each cabin door product during riveting supplementing. A total of 6 sets of full-set cabin door riveting supplementing tooling need to be manufactured to assist the riveting of cabin door products.

[0003] The above solution is a common method adopted by current aircraft assembly workshops, that is, customizing special clamping tooling for different cabin doors, and finally completing the riveting assembly manufacturing of various types of cabin door products. Using the above method will have the following problems:

[0004] (1) The utilization rate of the tooling is low. Since the riveting supplementing work is a small amount of work remaining after the main structure riveting is completed, customizing special tooling will result in a low utilization rate of the riveting supplementing tooling for each door, and the utilization rate of the tooling cannot be maximized.

[0005] (2) The large number of tooling leads to high manufacturing costs and occupies a large amount of production site area.

[0006] (3) To achieve the purpose of ergonomics, the current tooling needs to be used in conjunction with a work ladder to meet the riveting requirements at different height positions. Summary of the Invention

[0007] In order to solve the above technical problems, the present invention provides a liftable universal riveting supplementing tooling adaptable to different types of cabin doors, which can adapt to the clamping and positioning of 6 doors of 3 types, namely front / rear boarding doors, front / rear service doors, and front / rear cargo doors, through an adjusting frame assembly and a clamping device assembly.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

After the fork ends pass through both sides of the upper pressing plate assembly 03-01-04, their ports are connected to the lower pressing plate assembly 03-01-05 through pins. A tightening screw is installed in the middle of the other end of the pressing assembly 03-01-03, and the tail end of the tightening screw abuts against the upper pressing plate assembly 03-01-04. By tightening the tightening screw, clamping force is provided for the upper and lower pressing plate assemblies to clamp the hatch product.

[0015] The adjustable clamps 03-03, 03-04, 03-05 and 03-06 have basically the same structure, and each includes a base assembly 03-03-01, a fork assembly 03-03-02, a pressing assembly 03-03-03, an upper pressing plate assembly 03-03-04, a lower pressing plate assembly 03-03-05, pin A 03-03-06, pin B 03-03-07 and pin C 03-03-08.

PVC blocks are installed at the clamping ends of the upper pressing plate assembly 03-03-04 and the lower pressing plate assembly 03-03-05 to prevent scratching the hatch product. The pressing assembly 03-03-03 is a fork-shaped structural member. After the fork ends pass through both sides of the upper pressing plate assembly 03-03-04, their ends are connected to the lower pressing plate assembly 03-03-05 through pins. A tightening screw is installed in the middle of the other end of the pressing assembly 03-03-03.

By tightening the tightening screw, clamping force is provided for the upper and lower pressing plate assemblies to clamp the hatch product.

[0046] As Figure 7 (a) and Figure 7(b) The adjustable clamps 03-03, 03-04, 03-05 and 03-06 shown have basically the same structure, and each includes a base assembly 03-03-01, a fork assembly 03-03-02, a pressing assembly 03-03-03, an upper pressing plate assembly 03-03-04, a lower pressing plate assembly 03-03-05, pin A 03-03-06, pin B 03-03-07 and pin C 03-03-08.

There is an insertion plate 03-05-01 at its top. Openings are provided on the insertion plate 03-05-01 according to different hatch curvatures. The out-of-plane displacement of the adjustable clamp 03-05 is controlled through the through holes in the vertical direction of the upper frame assembly 02-01 in cooperation with the locking pin 03-05-02 to meet the requirements of different hatch curvature profiles.

[0048] The clamping component 03 is a component with adjustable degrees of freedom, which realizes adjustable degrees of freedom through 4 adjustable clamps. Specifically: the diameter of the pin A 03-03-06 is the same as the size of the corresponding opening on the ear fork component 03-03-02, and the diameter of the pin B 03-03-07 is 1 / 3 of the size of the corresponding opening on the ear fork component 03-03-02. The purpose is to ensure that the component composed of the pressing component 03-03-03, the upper pressing plate component 03-03-04, and the lower pressing plate component 03-03-05 can be finely adjusted and rotated around the pin A to achieve the purpose of adjusting the degrees of freedom in the warp direction; the diameter of the pin C 03-03-08 is 1 / 3 of the size of the corresponding opening on the sleeve structure of the base component 03-03-01. The purpose is to ensure that the component composed of the ear fork component 03-03-02, the pressing component 03-03-03, the upper pressing plate component 03-03-04, and the lower pressing plate component 03-03-05 can be finely adjusted and rotated within the sleeve structure to achieve the purpose of adjusting the degrees of freedom in the weft direction.

[0049] The following takes the former service door as an example to further elaborate on this repair riveting tooling in detail.

[0050] First, adjust the width of the frame component 02 according to the door type. Insert the locking bolt 02-05 into the pin holes on both sides of the vertical frames of the upper frame component 02-01 and the lower frame component 02-02 to lock it. Use the lift component 01-07 to adjust the overall height of the frame component 02 to meet ergonomics. Insert the pins 02-03 on the two corner seats on both sides of the lower frame component 02-02 into the stop plates 01-05 and 01-06 on the bracket component 01 to achieve the purpose of fixing the frame component 02, as Figure 8 shown.

[0051] Place the former service door product on the lower frame component 02-02. Lock the lower edges of the product at points A and B with the fixed clamps. Adjust the off-plane displacement of the adjustable clamp 03-05 at point C through the insertion plate 03-05-01, and insert the locking bolt 03-05-02 to form a three-point fixed lock of "one on top and two at the bottom" for the product.
