A multi-axis drilling device for pcd holes of aluminum alloy wheels

Abstract

The invention discloses a multi-axle drilling device of aluminum alloy hub PCD holes. The device comprises a drill bit main shaft; the drill bit main shaft includes a main shaft pull rod, an upper face plate, a lower face plate, a center drill, a first electric main shaft and a reinforcing rib, and also includes eight support modules; each support module includes a first motor, a support block, a rolling shaft, a rotating shaft, a locking nut, a bearing base, a sunk screw, a ball screw and a first coupling; a drill bit slide base is below each support module; and each rotating shaft is connected with a second motor. The device is simple in connection, convenient to operate and low in transformation cost, can synchronously drill a center hole and at most eight PCD holes of an aluminum alloy hub to improve the machining efficiency, and can automatically change relative angles and pitch diameters of PCD hole drill bits to reduce the production and the investment of process equipment so as to guarantee the quality of the PCD holes during machining of multiple holes.

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...
