Five degree-of-freedom combined robot platform

Abstract

The invention discloses a five degree-of-freedom combined robot platform. The five degree-of-freedom combined robot platform is characterized by comprising a two-dimensional workbench at the bottom and a three degree-of-freedom manipulator vertically installed at the top, the two-dimensional workbench comprises a displacement table moving in the X direction, and the displacement table is provided with a workbench body moving in the Y direction; the three degree-of-freedom manipulator comprises a ball screw spline shaft and a vertical rotary shaft penetrating through the ball screw spline shaft, the ball screw spline shaft moves linearly in the Z direction under the action of a ball screw bearing in the middle of the ball screw spline shaft and rotates around the vertical shaft under the action of a ball spline bearing, the lower end of the vertical rotary shaft drives a horizontal rotary shaft to rotate through two bevel gears, and the two ends of the horizontal rotary shaft are fixedly provided with a connection flange with a wrist. The five degree-of-freedom combined robot platform is reasonable in mechanical design, compact in structure, good in dynamic characteristic, capable of reducing the coupling effect between joints, and especially suitable for three-dimensional profile measurement of parts and automatic assembly tasks.

AI Technical Summary

Benefits of technology

This technology makes it possible to make things more precise by measuring their shape accurately with high precision while also being able to assemble them quickly without having any extra steps or tools needed during production process.

Problems solved by technology

This patented describes different technical problem addressed during 3D surface measurements (surfacing) with cartridge type manipulators such as carts and trucks. These devices have limitations due to their high weight and complicated movements caused by large amounts of force applied on them. Additionally, some designs require both hands to operate while also allowing for independent orientation within an object being measured. Therefore, new solutions must address issues related to achieving better performance without increasing costs associated with existing systems.
