The invention discloses an automatic wheel set centering device for wheel flaw detection. The device comprises a base, a sliding seat is arranged on the base in a sliding mode, and buffer mechanisms elastically connected with the base are arranged at the two ends of the sliding seat; a turntable mechanism is fixedly mounted at the top of the sliding seat and comprises a supporting disc fixedly installed at the top of the sliding seat and a movable disc rotationally arranged in the sliding seat, a spherical base is vertically and rotationally arranged in the center of the supporting disc, the periphery of the spherical base is symmetrically and rotationally connected with the inner ends of a plurality of rolling shafts, and the outer ends of the rolling shafts movably penetrate through theside wall of a movable disc. According to the invention, the accuracy of automatic centering and positioning and the stability of wheel set jacking during flaw detection of the wheels of the railway high-speed train unit can be met, and the accuracy of flaw detection data of railway high-speed train unit detection equipment is improved. When the position of the rotating disc needs to be limited, arotating handle is rotated to enable a limiting barrel to rotate downwards, the supporting wheel is limited between a limiting groove and an annular groove, so that the effect of fixing the positionof the rotating disc is achieved.
本发明公开了一种用于车轮探伤的轮对自动对中装置,包括底座,底座上滑动设置滑动座,滑动座的两端设有与底座弹性连接的缓冲机构;滑动座的顶部固定安装转盘机构;转盘机构包括:固定安装在滑动座顶部的支撑盘和转动位于滑动座内的活动盘,支撑盘中心位置竖向转动设置一个球形座,球形座的四周对称转动连接多个滚轴的内端部,滚轴的外端部活动贯穿活动盘侧壁。本发明能够满足铁路动车组车轮探伤时自动对中定位的准确性和轮对顶起的稳定性,提高铁路动车组检测设备探伤数据的准确性。当需要对转动盘的位置限制时,转动旋转把手,使得限位筒向下转动,将支撑轮限制在限位凹槽和环形槽之间,从而达到固定转动盘位置的作用。
