A structural design method for a double-speed translation mechanism of a robot

Abstract

The invention discloses a structural designing method for a robot multiple-speed translation mechanism and belongs to the field of mechanical equipment. The structural designing method includes simulating load borne by a main beam in actual working condition and analyzing to acquire dynamic load; applying the dynamic load onto the main beam, and calculating equivalent static load of the main beam; taking the equivalent static load of the main beam as a boundary condition to adopt a variable density method to perform topological optimizing design on structure of the main beam. By taking the equivalent static load of the main beam of the robot multiple-speed translation mechanism as the boundary condition, optimal material distribution of the main beam is acquired on the basis of the variable density method, and finally a multiple-speed translation mechanism with optimal comprehensive performance is acquired, so that maximum deformation can be reduced while structural weight is reduced, and working requirements on high speed and high accuracy of a robot are met.

Description

technical field [0001] The invention belongs to the field of mechanical equipment design, and relates to a structural design method, in particular to a structural design method suitable for a multi-speed translation mechanism of a robot. Background technique [0002] As a handling platform in an automated system, stamping robots have been widely used in the automotive and aerospace industries. Robot technology is becoming more and more perfect, and it is developing in the direction of high speed, high repeat positioning accuracy and small working space. [0003] However, due to the fast moving speed, the multi-speed translation mechanism of the robot will generate a large inertial force during high-speed movement, which will cause deformation of the parts and affect the positioning accuracy of the mechanism. At the same time, for the driving robot, the weight of the double-speed translation mechanism is an additional load. Therefore, reducing the mass of the double-speed tr...
