Description

Pneumatic clamp for aviation thin-wall part Technical Field The utility model relates to the technical field of clamps, in particular to a pneumatic clamp for an aviation thin-wall part. Background In the field of aerospace manufacturing, the fabrication of thin-walled parts is a critical and challenging task. Because of the structural characteristics of the aviation thin-wall parts (such as wing skins, engine blades and the like), namely thin wall and poor rigidity, the aviation thin-wall parts have extremely high requirements on positioning and clamping in the processing process. The proper clamp not only ensures the stability of the thin-wall part in the processing process, but also avoids the deformation problem caused by overlarge or uneven clamping force so as to ensure the processing precision and the product quality. Therefore, the clamp for processing the aviation thin-wall part is of great importance for the development of the whole aviation manufacturing industry. However, when the existing fixture for aviation thin-wall parts is used for machining aviation thin-wall parts with complex curved surfaces or irregular shapes, the traditional fixture is difficult to achieve accurate positioning and uniform clamping, many fixtures lack of effective adjusting mechanisms, and cannot be flexibly adjusted according to the specific shapes and machining requirements of the thin-wall parts, so that local stress concentration easily occurs in the machining process, the thin-wall parts are deformed, in addition, the design of the clamping mechanism of part of the fixture is unreasonable, and the fixture cannot be well adapted to scenes needing multi-angle adsorption or clamping, so that machining precision and efficiency are affected. Disclosure of utility model Therefore, the utility model provides a pneumatic clamp for an aviation thin-wall part, which aims to solve the problem that the pneumatic clamp cannot be well adapted to a plurality of scenes needing multi-angle adsorption or clamping in the prior art. In order to achieve the above object, the present utility model provides the following technical solutions: According to the first aspect of the utility model, the pneumatic clamp for the aviation thin-wall part comprises an adjusting mechanism, wherein the adjusting mechanism comprises a mounting frame, a guide rail fixedly connected with the inner wall of the mounting frame, a first cylinder is fixedly connected with the top of the mounting frame, a clamping mechanism comprises a fixing rod, the surface of the fixing rod is in sliding connection with the inner part of the mounting frame, and a limiting block is arranged at the upper end of the fixing rod. Further, the adjusting mechanism further comprises a mounting piece, and one side of the mounting piece is fixedly connected with the output end of the first cylinder. Further, the lower extreme fixedly connected with slide of installed part, the sliding tray has been seted up to the bottom of slide. Further, the inner wall of the sliding groove is in sliding connection with the surface of the guide rail, a locking piece is fixedly connected with the surface of the sliding plate, and one side of the locking piece is in lap joint with the surface of the fixed rod. Further, the inner wall fixedly connected with locating part of mounting bracket, one side of locating part and dead piece's one side overlap joint are kept away from to the dead lever. Further, the clamping mechanism further comprises a rotating ball sleeve, and the inner wall of the rotating ball sleeve is rotationally connected with a rotating ball. Further, the bottom of the rotating ball is fixedly connected with a sucker, and the surface of the sucker is provided with an air inlet. Further, the surface of the rotary ball sleeve is provided with a second air cylinder, and the output end of the second air cylinder is overlapped with the surface of the rotary ball. The utility model has the advantages that the angle of the sucker can be adjusted through the arrangement of the rotating ball sleeve and the rotating ball in the clamping mechanism, so that the angle of the sucker can adapt to the surface shapes of different aviation thin-wall parts, and meanwhile, in the adjusting process, the first motor can be started to drive the locking part to be separated from the fixed rod, thereby adjusting the height of the fixed rod, further adjusting the heights of different suckers, further expanding the adjustable range of the positions of the sucker, improving the adaptability of the clamp and being more convenient to use.
