Description

Technical Field

[0001] The utility model relates to a shape cutting fixture for aircraft parts. Background Art

[0002] Currently, titanium alloy hot-formed parts are widely used in aircraft. However, the size of the raw material of most titanium alloy parts increases during forming, which increases the workload and time cycle of removing the excess material in the later stage. In addition, such parts are produced in large quantities, with high labor costs and relatively low precision. Therefore, there is an urgent need for a shape cutting fixture for aircraft parts. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides a shape cutting fixture for aircraft parts.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a shape cutting fixture for aircraft parts, comprising:

[0005] pallet;

[0006] The feature is that: a hollow support frame is provided in the middle part of the top surface of the support plate, a part fixing plate with an arc structure is provided on the top surface of the support frame, a plurality of fixing seats are provided on the front and rear side walls of the support frame near the top, a tool pin is provided on the top surface of the fixing seat, a first marking block fixed on the support plate is provided on the left front side of the support frame, a second marking block fixed on the support plate is provided on the right rear side of the support frame, and a reference hole is provided on the left side of the second marking block.

[0007] In the above structure, two eye bolts are further provided on the top surface of the supporting plate.

[0008] In the above structure, a plurality of part limiting holes are provided on the top surface of the part fixing plate.

[0009] In the above structure, there are three fixing seats.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the structure design of the aircraft part shape cutting fixture of the present invention is reasonable, and a part fixing plate with an arc surface structure adapted to the part is provided, and a number of tool pins are provided to realize the positioning of the part, with accurate positioning, fast speed and high precision, which greatly improves production efficiency and reduces labor costs.
