Tool eccentricity offline adjusting method based on robot spiral hole milling platform

Abstract

The invention discloses a tool eccentricity offline adjusting method based on a robot spiral hole milling platform. The robot spiral hole milling platform comprises a feeding mechanism, a revolution driving mechanism, an eccentric main shaft unit, a rapid butt joint module, a hole making tool mechanism and a tool setting table. The tool eccentricity offline adjusting method comprises the following steps: calculating a theoretical value of tool eccentricity, and determining a maximum allowable error for adjusting the tool eccentricity; making the tool setting table be in butt joint with a revolution adjusting mechanism and a rotation adjusting mechanism in a butt joint posture; adjusting the hole making tool mechanism to actual eccentricity during hole making; and taking the eccentric main shaft unit away from the tool setting table. According to the tool eccentricity offline adjusting method, the eccentricity of the hole making tool mechanism can be adjusted through the tool setting table, the adjusting precision of the revolution radius of a tool is guaranteed, the hole making tool mechanism has the spiral hole milling capability and the hole drilling capability, and the hole making quality and efficiency of a robot can be greatly improved.

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.
