Abstract

The invention relates to a multi-axis linkage device capable of realizing five-surface machining and belongs to the technical field of numerical control device. The multi-axis linkage device comprises a movable platform, a fixed platform, a U-shaped frame, a support, a first, a second, a third, a fourth and a fifth branched hinge; the first, the third and the fifth branched hinge are connected between the fixed platform and the U-shaped frame, and the second and the fourth branched hinge are connected between the movable platform and the fixed platform. The multi-axis linkage device is characterized in that the first, the third and the fifth branched hinge are respectively connected with the fixed platform and the U-shaped frame, the U-shaped frame is connected with the support through one revolute pair, the support is connected with the movable platform through one revolute pair, and the second and the fourth branched hinge are respectively connected with the fixed platform and the movable platform, so that a spatial parallel-connection closed-loop mechanism is formed and three degrees of moving freedom and two degrees of rotational freedom of the movable platform are realized by means of driving of five inputs. The multi-axis linkage device further comprises a circular guide rail or worktable, and the spatial parallel-connection closed-loop mechanism and the circular guide rail or the worktable form a mixed-link device capable of realizing six-axis linkage. According to the structural form, the multi-axis linkage device can realize high rotation output and switching between vertical and horizontal modes.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a multi-axis linkage device which can realize five-face machining and can be applied in the field of numerical control device manufacturing. Background technique [0002] In the field of mechanical processing and manufacturing, the design and processing technology of modern parts are becoming more and more complex, and space free-form surface parts have been widely used in various key fields, such as aerospace, automobiles, turbine blades, etc. In order to obtain better rotation flexibility, processing equipment should have at least two-axis linkage rotation output capability; in order to obtain better processing flexibility, modern processing equipment should have at least five-axis linkage processing capability, which requires processing under harsh conditions. The equipment can realize five-sided machining in one clamping. Therefore, five-axis linkage or mor...
