Detachable combined notch template and application method thereof

Abstract

The invention belongs to the field of aeronautical manufacture engineering, and provides a detachable combined notch template and an application method thereof. The detachable combined notch template comprises four milling and cutting template assemblies forming a continuous closed loop. Every two adjacent milling and cutting template assemblies share one positioning basic hole, in other words, the number of the positioning basic holes is four, each positioning basic hole is used by each of the two corresponding milling and cutting template assemblies once, and therefore the four milling and cutting template assemblies are independently used. The four milling and cutting template assemblies each mill and cut a gate frame skin by a distance when independently used, a complete closed loop can be formed by the four milled and cut parts of the gate frame skin, and the milling and cutting work of the whole gate frame skin is completed. The detachable combined notch template is simple in structure and can be repeatedly detached and used, the allowance selection of a metal plate skin is sufficiently considered during design, and the field operation can be more user-friendly.

Description

technical field [0001] The invention belongs to the field of aviation manufacturing engineering, and relates to a detachable combined incision template and a using method thereof. Background technique [0002] The finishing device is mainly used to complete the finishing work such as reaming, face milling, skin milling and other finishing work of butt joint reaming, face milling and skin milling of aircraft parts or segments. At the same time, it can jointly complete some joint, drilling, compensation processing and other work. [0003] The skins of aircraft are generally sheet metal parts. Sheet metal parts are processed at room temperature or high temperature (400 to 700 degrees), using materials such as steel plates, aluminum plates, and titanium plates that are relatively soft and ductile. Sheet metal processing equipment tools or thermoforming equipment, the process of manufacturing products of various shapes and structures. The production process of sheet metal proce...

Problems solved by technology

[0005] It is used for the milling and finishing device of the aircraft door frame. Due to the large size of the aircraft door, if the cutting device is made as a whole, the weight will be heavy, which is not conducive to the operation and handling of the workers on site, and it is extremely inconvenient to use.
