Abstract

The invention relates to a five-axis hybrid machine tool for machining aviation structural parts, and belongs to the technical field of mechanical manufacturing. The five-axis hybrid machine tool comprises brackets, a front crossbeam, a rear crossbeam, a first branch chain, a second branch chain, a third branch chain, a fourth branch chain, a movable platform, a main shaft head and a sliding table, wherein the main shaft head is fixed to the movable platform; the four branch chains have the same structure and are provided with moving pairs capable of moving in the length direction of the branch chains; the front crossbeam and the rear crossbeam are connected with the brackets through the rotating pairs; one end of the first branch chain and one end of the second branch chain are separatelyconnected with the front crossbeam through the rotating pairs, and the other end of the first branch chain and the other end of the second branch chain are separately connected with the movable platform through the rotating pairs; and one end of the third branch chain and one end of the fourth branch chain are separately connected with the rear crossbeam through the rotating pairs, and the otherend of the third branch chain and the other end of the fourth branch chain are separately connected with a Hooke pair fixed to the movable platform through the rotating pairs. The five-axis hybrid machine tool for machining the aviation structural parts has the advantages of good dynamic characteristics and high rigidity to weight ratio and can realize higher machining efficiency and better machining precision, so that the five-axis hybrid machine tool for machining the aviation structural parts is very suitable for high-efficiency and high-precision machining of the aviation structural parts.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a five-axis hybrid machine tool used for machining aerospace structural parts. Background technique [0002] Advanced overall structural design is widely used in modern aircraft design. This design method can significantly improve aircraft performance, but it leads to complex shapes of parts, large changes in the internal and external angles of parts, etc., which increases the difficulty of parts processing. In addition, in order to reduce the weight of the aircraft, the wall thickness of the structural parts is getting thinner and thinner, and the material removal rate reaches more than 90%, so the cutting process is huge, and the parts are very easy to deform during processing. It can be seen that the overall structure of aviation has the characteristics of large size, thin wall, easy deformation, difficult cutting and high precision of parts. [0003] Traditional five-...
