At present, with gradually increasing performance index requirement of aerospace vehicle, structural / functional integrated composite material workpiece application is also more and more extensive. The half closed back -shaped structure composite material workpiece of the utility model contains metal wire belt inside, and it belongs to structural / functional integrated product. In the manufacturing process, because the electrical performance test and riveting wire interface need to be carried out, the back -shaped structure opening place needs to be repeatedly opened. Because the outside wall of back -shaped structure is thin, and the metal wire belt is evenly distributed inside and on the surface, the opening is too large to cause the metal wire belt to break, the composite material to break and the layered product to be scrapped, and the maximum opening width is 52mm. At the same time, because the outside wall of back -shaped structure is thin, the outside composite material has certain resilience, so too small opening loses operation space.

[0003] The traditional supporting mode is to insert the foam block of specified thickness into the opening, and the opening is opened to the width convenient for operation. Because the foam block can only support the composite material around it, the foam block needs to be moved in the process, which causes the opening to be repeatedly opened, and the metal wire belt is easily broken, the composite material is easily broken and layered, and the actual operation is very inconvenient.

[0014] Technical effect

[0015] The utility model provides a device of accurate control half closed loop structure composite material opening width, through the fastening bolt of screwing support rod, makes whole device fixed on horizontal vertical component. Again through the stretching guide rod and the fastening bolt of screwing, fixed support width. The support plate is used for pressing against the outer wall of the loop structure to prevent its rebound. The support plate can also press against the hands of the operator and the tool during operation to continue to enlarge the opening.

[0016] Both ensure the operation space and improve production efficiency, and can avoid the breakage of metal wire and the breakage and delamination of composite material caused by repeated opening, and reduce the incidence of quality problems. DRAWINGS
