The invention discloses a floating and overturning type motor pressing assembling trolley which comprises an overturning mechanism and a trolley body. The overturning mechanism is fixedly arranged onthe trolley body and is used for assembling a gearbox body to the trolley body so that the pressing assembling action of a motor in the gearbox body can be conducted conveniently. The overturning mechanism comprises a positioning plate and a fixing plate, the fixing plate and the trolley body are fixedly connected, the positioning plate and the fixing plate are connected in a floating manner, andthe positioning plate can overturn at will in six freedom degrees relative to the fixing plate.

An integral co-curing molding method for an unmanned aerial vehicle wing belongs to the field of aviation composite material molding. The method steps are: step 1: assembling the wing frame; step 2: assembling the lower mold; step 3: making the lower wing surface skin of the wing in the assembled lower mold mold, and reserving the upper wing surface skin when paving step 4: positioning the wing frame; step 5: making the upper wing surface skin; step 6: assembling the upper mold; step 7: curing and demoulding. The wing prepared by the method of the present invention can be molded at one time, which improves the strength, saves the cost, and improves the manufacturing speed.

The invention discloses a tenon root and front and rear edge machining clamp of a precisely-forged blade. The tenon root and front and rear edge machining clamp is composed of a pouring box, a supporting arm, a pressing plate and a rotary table. The blade is located in a cavity of the pouring box through assembly of the pouring box and the blade. The molded surface of a blade body is clamped through low-melting-point alloy solidification, and the clamp is prevented from generating clamping injuries to the molded surface of the blade body. The pouring box is pressed and fixed through the pressing plate, pressing force is evenly transmitted to the pouring box through the pressing plate, the pouring box is pressed, and clamping deformation of the blade cannot be caused. To-be-machined parts of a tenon root and front and rear edges of the blade are located outside the pouring box, and numerical control machining of the tenon root and the front and rear edges of the blade is completed through one-time clamping. According to the clamp, clamping errors and the number of tools are reduced, meanwhile, the machining technological process of the precisely-forged blade is optimized, and the machining precision and machining efficiency of the precisely-forged blade are improved. The clamp is suitable for efficient and batched numerical control machining of aero-engine precisely-forged blades and can also be used for machining of tenon roots and front and rear edges of rolled blades and other precisely-formed blades.

The invention discloses a rectifying blade body end face position measuring device and method, and the device comprises a first positioning V-shaped block and a second positioning V-shaped block whichare respectively used for positioning an upper shaft neck and a lower shaft neck of a rectifying blade, and also comprises a positioning unit; an upper shaft neck side blade body end face limiting block and a lower shaft neck side blade body end face limiting block are arranged on the outer side of the first positioning V-shaped block and the outer side of the second positioning V-shaped block respectively and connected with a first gauge stand and a second gauge stand respectively in a matched mode; the upper sides of the first gauge stand and the second gauge stand are respectively connected with dial gauges used for measuring an upper shaft neck side blade body end face and a lower shaft neck side blade body end face, an upper shaft neck side blade body end face gauge checking member and a lower shaft neck side blade body end face gauge checking member are arranged between the upper shaft neck side blade body end face limiting block and the lower shaft neck side blade body end facelimiting block.
