Multi-axis drilling method of PCD holes of aluminum alloy hub

Abstract

The invention discloses a multi-axis drilling method for an aluminum alloy wheel PCD hole, which includes a drill spindle, which includes a spindle pull rod, an upper faceplate, a lower faceplate, a center drill, a first electric spindle and reinforcing ribs, and eight supporting components. It includes the first motor, supporting block, rolling shaft, rotating shaft, lock nut, bearing seat, countersunk screw, ball screw and the first coupling. There is a drill slide under each supporting assembly, and each rotating shaft is connected to the first coupling. The two motors are connected. The invention has the advantages of simple connection, convenient operation and low modification cost. It can drill the center hole of the aluminum alloy wheel hub and up to eight PCD holes at the same time, which improves the processing efficiency, and can automatically change the relative angle and pitch circle diameter of the PCD hole drill, reducing the process The production and investment of equipment ensure the quality of PCD holes during porous processing.

AI Technical Summary

Benefits of technology

This patented technology allows for precise movement and rotation of various parts within an industrial robot's turntable while maintaining accurate hole depth measurements. Unlike previous methods where all the necessary hardware was previously needed, this new method uses two motors instead of just three. Additionally, there were also improvements over current systems such as single axis servo machines (SPM) allowing for more flexibility in accommodate varying hole sizes and shapes than before. Overall, these technical features improve the performance and precision of the robots involved in performing high-volume operations like plasma etchings.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency and precision of machining processes for wheel designs with multiple types or sizes of pins that may vary from each other due to differences between manufacturer's specifications. Current methods require manually changing drilling parameters during the drilling process which takes longer than necessary but still results in imprecise hole depth values.
