Problems solved by technology

Although this scheme of independently configuring the tool revolution radius adjustment mechanism realizes the advantages of online adjustment, it results in a large weight of the power head and a high degree of integration, it is difficult to control the adjustment accuracy of the tool revolution radius, and it is inconvenient to change the tool.
These factors have hindered the popularization and application of robot helical milling holes to a certain extent.

Abstract

The invention discloses a power head convenient for a robot to automatically exchange an eccentric main shaft unit. The power head comprises a power head support, 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, wherein the eccentric main shaft unit comprises a revolution adjusting mechanism and a rotation adjusting mechanism. According to the power head convenient for the robot to automatically exchange the eccentric main shaft unit, detachable butt joint mounting of the revolution driving mechanism and the revolution adjusting mechanism can be realized by utilizing the rapid butt joint module, so that the corresponding eccentric main shaft unit can be conveniently and quickly exchanged, offline adjustment of the revolution radius of the hole making tool is realized, the structure of the power head is simplified, and the weight of the whole power head is reduced; and the eccentricity of the hole making tool mechanism can be adjusted by 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 the robot can be greatly improved.

Description

technical field [0001] The invention relates to a power head, in particular to a power head which is convenient for a robot to automatically exchange an eccentric main shaft unit. Background technique [0002] Robotic hole making has broad application prospects in improving the quality and efficiency of large workpiece hole making due to its advantages of large operating range, high processing efficiency, and low system manufacturing cost. Then, the weak rigidity and low load-bearing characteristics of the robot body as a carrier make it particularly demanding on the working performance of the drilling power head. In order to avoid the excessive axial force of traditional drilling, the power head based on the helical milling mechanism has become a research hotspot in the modern aerospace manufacturing industry. [0003] From the perspective of processing mechanism, the helical milling power head has technological advantages such as hole-making axial force, small tool wear, ...
