Fourth shaft rotary processing device of processing center special for steering knuckle

Abstract

The invention discloses a fourth shaft rotary processing device of a processing center special for a steering knuckle. The device comprises a bridge plate which takes the fourth shaft as a center to rotate; at least one steering knuckle placing hole for containing steering knuckle shaft necks to pass through is arranged on the bridge plate; a clamping device and a pressing device for fixing the steering knuckle on the bridge plate are arranged on the bridge plate; and a steering positioning device is arranged on the bridge plate. Through once clamping, the coarse and fine boring of a main pin hole of the steering knuckle, the finish milling treatment of the fork ear external surface of the steering knuckle and the ABS (acrylonitrile-butadiene-styrene) hole processing can be carried out; the processing precision can be guaranteed, the processing total time of the steering knuckle is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to steering knuckle processing equipment, in particular to a fourth-axis rotary processing device for a processing center dedicated to steering knuckles. Background technique [0002] Steering knuckles have special requirements for production and processing equipment due to their use environment and structural characteristics, such as Figure 6 A steering knuckle 5 is shown, which includes a steering knuckle flange 51, a steering knuckle journal 52 arranged on one side of the steering knuckle flange 51, and two oppositely arranged steering knuckle yokes 53 on the other side. A kingpin hole is provided on the fork ear 53, and a mounting hole 54 for installing a brake disc and an ABS hole 55 for installing an ABS device are provided on the steering knuckle flange 51, wherein the axis of the kingpin hole is aligned with the steering knuckle flange. The included angle of the 51 disk surface is 9°, and its dimensional accuracy requires...

[0002] Steering knuckles have special requirements for production and processing equipment due to their use environment and structural characteristics, such as Image 6 A steering knuckle 5 is shown, which includes a steering knuckle flange 51, a steering knuckle journal 52 arranged on one side of the steering knuckle flange 51, and two oppositely arranged steering knuckle yokes 53 on the other side. A kingpin hole is provided on the fork ear 53, and a mounting hole 54 for installing a brake disc and an ABS hole 55 for installing an ABS device are provided on the steering knuckle flange 51, wherein the axis of the kingpin hole is aligned with the steering knuckle flange. The included angle of the 51 disk surface is 9°, and its dimensional accuracy requires an upper tolerance of 0.039mm and a lower tolerance of 0, and the outer crotch surface of the two steering knuckle lugs 53 needs to be fine-milled. If different machine tools are used for processing, the main It is difficult to control the precision of the angle of the pin hole and the precision milling of the outer crotch surface of the steering knuckle yoke 53, and the position requirements of the ABS hole 55 are relatively strict. At the same time, if the above-mentioned processing is performed on different machine tools, most of the time is spent on loading and unloading the workpiece, and the workpiece is heavy. Only one processing is performed after one clamping, which greatly increases the total processing time of the product. , reducing production efficiency
