Abstract

The invention discloses an industrial robot rigidity measurement loading device and a measurement thereof. The loading device comprises the components of a rotating base which can perform rotation along a horizontal plane; a force transmission seat which is fixedly connected with the rotating base and is internally provided with a lead screw that is rotatably arranged, wherein a lead screw nut sleeves a lead screw, and a hinging seat is fixed on the lead screw nut; and a connecting rod of which one end is hinged with the hinging seat, wherein the connecting rod can rotate in a vertical surface. A spring sleeves the connecting rod through a spacing assembly. A sleeve is arranged outside the spring. One end, which is far from the hinging seat, of the sleeve is provided with a connecting sleeve. The outer end of the connecting sleeve is connected with the end of an industrial robot. The industrial robot rigidity measurement loading device has advantages of simple structure, convenient operation, wide application range, high measurement efficiency. The industrial robot rigidity measurement loading device can realize measurement for static rigidity of the robot in an X-direction, a Y-direction and a Z-direction.

Description

technical field [0001] The invention belongs to the technical field of robot performance testing, and in particular relates to an industrial robot stiffness measurement loading device and a measurement method for measuring the static stiffness of a robot in three directions. Background technique [0002] An industrial robot is an automatic control, reprogrammable, multi-functional, multi-degree-of-freedom manipulator, which can carry materials, workpieces or manipulate tools to complete various operations. Compared with CNC machine tools, in addition to the low absolute positioning accuracy of robots, structural rigidity is also an important factor affecting their processing performance and end accuracy. It is mainly manifested in the following aspects: (1) The multi-link series coupling mechanism has poor stiffness and structural stability; (2) The motor and transmission mechanism are generally placed on the running connecting rod, which deteriorates the dynamic performance...
