Embodiment approach 1
[0039] This embodiment, as a basic embodiment of the present invention, discloses a turning device for the processing of aircraft long truss parts. The specific structure is as follows: figure 1 As shown, it includes a frame 1, the frame 1 is provided with a support 2, and two sets of lifting mechanisms are symmetrically arranged on both sides of the frame 1;
[0040] The bracket 2 includes a connecting rod 21, a left supporting plate 22 and a right supporting plate 23, and the left supporting plate 22 and the right supporting plate 23 are respectively located on both sides of the connecting rod 21 and fixedly connected together to form a U-shaped structure; The lifting mechanism includes a lifting plate 5 and a mounting frame 6. The cross section of the mounting frame 6 is L-shaped, and the vertical side of the mounting frame 6 is vertically fixedly connected with the frame 1, thereby forming a space for placing equipment; along the vertical direction, Two sets of rotating fram...

The invention discloses a turnover device for machining aircraft stringer parts. The device comprises a rack, a bracket is arranged on the rack, two clamping and overturning mechanisms are symmetrically arranged on the two sides of the bracket, a supporting mechanism is also arranged on the rack, and the supporting mechanism is positioned between the two clamping and overturning mechanisms, and is in contact with the suspended area of a stringer in the working process; during use, the two clamping and overturning mechanisms fixedly clamp the stringer from the two sides of the stringer respectively, then the stringer is driven to turn over through synchronous rotation of the two clamping and overturning mechanisms, manual turnover is replaced by automatic equipment, the labor intensity of workers can be reduced, and the turnover stability of the equipment is higher; and meanwhile, the supporting mechanism is arranged between the two clamping and overturning mechanisms and makes contact with a middle suspension area of the stringer in the working process, so that stable supporting is provided, the stringer is prevented from being bent, meanwhile, the stability in the overturning process can be further improved, and damage to the stringer is avoided.
Description
technical field [0001] The invention relates to the technical field of aircraft manufacturing equipment, in particular to a turning device used for processing aircraft long truss parts. Background technique [0002] Long truss structural parts are one of the important components of the aircraft fuselage, and their good design efficiency and design quality are one of the foundations to ensure the overall efficiency and performance of aircraft design and manufacturing. Since the long stringer is generally designed as a slender structure and the wall thickness is quite thin (the length is generally 3-6 meters); it is not only difficult to process during the processing process, but also needs to be turned over after processing one side of each long stringer, and then the next side processing; [0003] In the prior art, the flipping of the stringers is done manually, that is, two operators respectively hold the two ends of the stringers and flip them in one direction at the same...
