In the assembly of an aircraft component skin, in order to accurately position the skin, it is generally required to add one or more process tabs to the edge of the skin part during manufacture, and to provide positioning holes in the tabs. After assembly, the ear is typically cut manually using a cutting tool to bring the product to a design state. Due to poor stability of manual cutting, the problems of uneven edges, rough edges and the like of the skin are often caused after the cutting is finished, and particularly, the poor stability of the composite material skin can cause irreparable damage to the skin. The problem can be solved by adopting a machine tool for cutting, but because the structure of the airplane part is large and complex, the skin after the assembly is finished becomes a part of the part and cannot be detached, the lug cutting difficulty is large by adopting the machine tool, and the operability is low.
Therefore, it is necessary to provide a light-weight skin tab cutting device, which can achieve accurate, stable and high-quality cutting of skin tabs after the product assembly is completed.

Detailed Description
The structure of the device is shown in figures 1 and 2, and a motor 1 is fixed on a cutting platform 7, is connected with a ball screw 2 and can drive the ball screw 2. The cutter seat 5 is connected with the ball screw 2. The cutter seat 5 is clamped with a cutting tool 3, and the cutting tool 3 is provided with a cutter 4. The cutter 4 is rotated by activating the cutting tool 3. The cutting platform 7 has a cutting groove 13 in the middle, as shown in fig. 3, the cutter 4 is located in the middle of the cutting groove 13, and two parallel linear sliding rails 10 are installed on both sides of the cutting groove 13. Limiting blocks 6 are arranged on two sides of the linear sliding rail 10 to prevent cutting overtravel. To ensure that the tool 4 can be machined smoothly, the cutting slot 13 is dimensioned to allow sufficient space for the entry and exit of the tool 4 and for the cutting of the tooling lugs 15, as shown in fig. 2. Two ends of the lower surface cutting groove 13 of the cutting platform 7 are provided with downward skin edge limiting pins 8, and the connecting line of the skin edge limiting pins 8 and the skin edge attaching points coincides with the cutting line of the cutter 4.
