An off-line adjustment method of tool eccentricity based on robot helical milling platform

Abstract

The invention discloses an off-line adjustment method for tool eccentricity based on a robot helical hole milling platform. The robot helical milling platform includes a feed mechanism, a revolution drive mechanism, an eccentric spindle unit, a quick docking module, a hole making tool mechanism and The tool setting table; the off-line adjustment method of the tool eccentricity includes: calculating the theoretical value of the tool eccentricity, and determining the maximum allowable error of the tool eccentricity adjustment; Attitude docking; adjust the hole-making tool mechanism to the actual eccentricity during hole-making; remove the eccentric spindle unit from the tool setting table. The off-line adjustment method of tool eccentricity uses the tool setting table to adjust the eccentricity of the hole-making tool mechanism to ensure the adjustment accuracy of the tool revolution radius, so that the hole-making tool mechanism has two capabilities of helical milling and drilling, which can greatly improve the robot. Hole quality and efficiency.

Description

technical field [0001] The invention relates to an off-line adjustment method for tool eccentricity, in particular to an off-line adjustment method for tool eccentricity based on a robot helical milling hole platform. Background technique [0002] Robot helical milling has broad application prospects in improving the quality and efficiency of large-scale workpiece hole-making due to its advantages of large hole-making range and high processing efficiency. However, as the transport carrier of the helical milling hole, the weak rigidity and low load-bearing characteristics of the robot body make it particularly demanding on the performance of the helical milling actuator. In the hole making process, the adjustment of the tool eccentricity of the helical milling actuator is a particularly critical process link. The adjustment method will not only affect the machining accuracy of the helical milling hole, but also determine the composition of the actuator and the weight of the w...

AI Technical Summary

Problems solved by technology

At present, the eccentricity adjustment of the robot helical milling tool mainly adopts online adjustment, which requires an independent configuration of the tool eccentricity adjustment mechanism, resulting in heavy weight and high integration of the helical milling actuator, and it is also inconvenient to change the tool.

These factors have hindered the popularization and application of robot helical milling holes to a certain extent.
