The invention discloses a telescopic wheel type polishing tool and aims at being used for improving the accuracy and the efficiency when a robot performs automatic polishing on an aeroengine blade. The telescopic wheel type polishing tool comprises a drive mechanism, a telescoping mechanism and a polishing mechanism; the drive mechanism comprises a base, a hand wheel, a lead screw sliding block, alead screw rod and a connection block; the base is fixed on the ground; a screw rod formed by the lead screw sliding block and a lead screw rod is connected to the base through a bearing; the hand wheel is fixedly connected with the screw rod in an interference fitting manner; the connection block is fixedly connected to the lead screw sliding block and is engaged with a first stud bolt in the telescoping mechanism through threads; the telescoping mechanism comprises the first stud bolt, an upper end shaft, a spring shock absorber, a second stud bolt and a lower end shaft; the lower end of the lower end shaft is fixedly connected with a tank body of the polishing mechanism; the polishing mechanism comprises a servo motor, a tank body, a polishing rolling wheel, polishing abrasive paper, acoupling, a movement shaft and a flat key; the movement shaft is connected with an output shaft of the servo motor through the coupling; the polishing rolling wheel is in key joint to the movement shaft through the flat key; and the polishing abrasive paper is adhered to the polishing rolling wheel.
Description
technical field [0001] The invention relates to a polishing tool for aeroengine blades. Background technique [0002] The aero engine mainly compresses and expands the gas through the blades, so as to generate the most efficient power to propel the aircraft forward. However, as one of the key parts in the aero-engine, the blade has the characteristics of complex curved surface structure, difficult material processing, and thin-walled structure. Therefore, manufacturing blades with high geometric precision and good surface quality has decisive significance for the performance and quality of the engine. As the last process of blade processing, polishing needs to ensure its surface roughness and shape accuracy requirements, so that it has good surface quality and achieves its best performance. [0003] Aeroengine blades have high requirements for surface roughness and precision, and the curved surfaces have irregular shapes. If manual polishing is used, the efficiency is low...
