Description

Technical Field

[0001] The utility model relates to a laser cutting positioning plate for a sheet metal part. Background Art

[0002] Titanium alloy materials (Ti-6AL-4V) have excellent performance and are increasingly widely used in the aerospace field. There are more and more types of titanium alloy parts on aircraft, and the shapes are also various. Usually, during the processing of titanium alloy sheet metal parts, the shape of the sheet metal parts has a curved surface during manual sawing, and there is a sawing margin, so the parts need to be polished after manual sawing. It is extremely difficult to ensure a uniform and smooth shape during the grinding process of sheet metal parts, which causes errors in the positioning reference of the subsequent hole making process, thereby affecting the processing quality and processing efficiency, and the manual processing cost is high. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides a light cutting positioning plate for a sheet metal part.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a laser cutting positioning plate for sheet metal parts, comprising:

[0005] Positioning substrate;

[0006] The invention is characterized in that a part cutting hole is arranged in the middle part of the top of the positioning substrate, two drill sleeves are arranged on the left and right sides of the part cutting hole, and a cross positioning line is arranged on the right side of the part cutting hole near the front end.

[0007] In the above structure, the positioning substrate is a rectangular positioning substrate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the optical cutting positioning plate structure of the sheet metal part of the utility model is reasonably designed, cutting holes and drill sleeves are set on the positioning substrate, the parts can be fixed in the drill sleeve by positioning pins, and a cross positioning line is set as a laser cutting reference point. The parts are placed on the positioning substrate for multiple times, thereby laser cutting the parts; the sheet metal processing efficiency is greatly improved, and the processing is simple, the installation is convenient, the dimensional tolerance is reasonable, and the processing quality of the parts is guaranteed.
