Six-freedom-degree adjusting platform

Abstract

The invention discloses a six-freedom-degree adjusting platform which comprises a fixed platform. A fixed seat is arranged on the upper surface of the fixed platform. A feed lead screw is mounted on the fixed seat. A first coupling is arranged at one end of the feed lead screw. A first planetary reducer is arranged at one end of the first coupling. One end of the first planetary reducer is connected with the output end of a front-and-back feed servo motor. The feed lead screw is sleeved with a first feed nut. A sliding platform is arranged at the upper end of the first feed nut. The platform does not require high adjusting precision but requires bearing capacity, and therefore all above screw pairs adopt trapezoidal lead screws capable of achieving self locking, and positions can be kept and the load rate can be improved conveniently during shutdown; and posture adjustment of six freedom degrees of a workpiece can be achieved, the posture of the workpiece can be rapidly adjusted in position, efficiency is high, labor intensity is small, and a mechanism is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of space position and space attitude adjustment equipment, and the specific field is a six-degree-of-freedom adjustment platform. Background technique [0002] In the fields of industrial automation, aerospace, rail transit, and national defense equipment, flexible assembly systems have been widely used, such as engine assembly, planetary reducer assembly, turbine assembly, etc. All flexible assembly applications require assembly tooling to have multi-station, multi-process, and mobile integration features. Taking the automobile industry, where the flexible assembly system is relatively mature, as an example, the system integrates equipment such as balance booster cranes, rotating cranes, suspension conveyor lines, and rail cars. The utilization rate of workshop space is low. [0003] In order to increase the degree of freedom of attitude adjustment of a single device, people use a positioner with extended...

AI Technical Summary

Problems solved by technology

Among them, the positioner scheme is simple and easy to use, but its disadvantage is its weak carrying capacity; the joint crane scheme has a strong carrying capacity, but its shortcoming is that it needs more precise synchronous control; the Stewart parallel mechanism is currently an ideal stand-alone six-degree-of-freedom solution, but It requires a large height space for heavy load capacity
