Small aero-engine hydraulic assembling frame

Abstract

The invention belongs to the field of aerospace manufacture, and relates to a small aero-engine hydraulic assembling frame. It is mainly ensured through the frame that in the small aero-engine transmission and final assembly process, installation, detachment, detection and other operations of all pats are all conducted on the optimum working plane, and therefore the convenience, standardization and controllability of the assembling operation of a small aero-engine are improved, and the labor intensity and risk and operators are reduced. Two hydraulic cylinder mechanisms and two limiting sliderod mechanisms of the assembling frame are symmetrically fixed to the edges of the two sides of the upper end face of a bottom round table, the bottoms of lifting platform mechanisms are fixed to oneends of piston rods of hydraulic cylinders, the tail ends of cantilevers of the two sides of the lifting platform mechanisms are provided with sleeve bearing pedestals. Polished rods of the limiting slide rod mechanisms are matched with ball bearings. Rotating shafts on the two sides of a turning supporting mechanism are matched with through holes in the upper ends of the corresponding lifting platform mechanisms. The rotating shaft on one side is connected with an output shaft of a speed reducer motor and can control the turning supporting mechanism to circumferential turn and be locked at any circumferential position.

Description

Technical field [0001] The invention belongs to the field of aviation manufacturing engineering and relates to a hydraulic assembly frame of a small aviation engine. Background technique [0002] At present, small aero engines are widely used in unmanned aerial systems, ammunition systems and other fields, but the corresponding assembly frame still adopts a fixed mechanical mode, a single structure, and insufficient space operation freedom, resulting in some components in the assembly and disassembly process For example, when installing low-pressure turbine rotors, internal nozzles and other rear-end components of the body, it is often necessary for the operator to repeatedly climb up and down on the working platform, and install the oil tank and accessories. When the front-end parts of the body such as the casing, the operator has to maintain a half-squatting position to operate, which is time-consuming and laborious, which seriously affects the assembly quality and efficiency o...
