Multi-shaft drilling device for aluminum alloy hub PCD holes

Abstract

The invention discloses a multi-axis drilling device for aluminum alloy wheel PCD holes, 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 a reinforcing rib, 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, each supporting assembly has a drill slide, and each rotating shaft is connected to the first The two motors are connected. The invention has the advantages of simple connection, convenient operation and low modification cost, and 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 bit, reducing the process The production and investment of equipment ensure the quality of PCD holes during porous processing.

Description

technical field [0001] The invention relates to the field of processing, in particular to a multi-axis drilling device for PCD holes of aluminum alloy wheels. Background technique [0002] Aluminum alloy wheels have different PCD holes according to different manufacturers and models. Their numbers and pitch circle diameters are not consistent. CNC machine tools are often used to process PCD holes. The drills are controlled by CNC programs and drilled one by one. Mass production will A waste of processing time; you can also use a multi-hole drill to drill the shape at one time. Using a fixed multi-hole drill, you need to re-make the multi-hole drill every time you change a model of hub. The cost is large. Use a manual adjustable multi-hole drill. For different models of hubs, the hole spacing and quantity need to be readjusted. Manual operation is time-consuming and labor-intensive, and the accuracy is not high. Contents of the invention [0003] The purpose of the present...
