The invention relates to the technical field of calibration equipment, and discloses a wheel train centering calibration tool which is characterized in that a threaded hole is formed in one end of a threaded sleeve, the threaded hole is connected with a double-threaded rod in a sleeving mode, the tool comprises a top plate, and supporting plates are fixedly installed at the positions, close to the two ends, of the bottom of the top plate; a threaded hole is formed in one end of a threaded sleeve and connected with a double-threaded rod in a sleeving mode, the rotating direction of a thread a is opposite to that of a thread b, the threaded sleeves located on the two sides of the double-threaded rod can synchronously draw close to the middle, and the limiting device is always kept in the middle of positioning devices on the two sides in the process; when the contact plate on one side is in contact with the front wheel set or the rear wheel set before the contact plate on the other side is in contact with the front wheel set or the rear wheel set, the double-threaded rod can still be kept in the middle position in the rotating process; the problem that positioning is not in the middle due to the fact that positioning devices on the two sides of a traditional calibration tool are designed in a split mode and errors occur when the middle position is determined in a measurement mode is solved, and the positioning accuracy of the device is improved.
本发明涉及校准设备技术领域,且公开了一种轮系对中校准工装,通过螺纹套筒的一端开设有螺纹孔且该螺纹孔与双螺纹杆套接,包括顶板,顶板底部靠近两端的位置上固定安装有支撑板,通过螺纹套筒一端开设有螺纹孔且该螺纹孔与双螺纹杆套接,螺纹a和螺纹b的旋转方向相反,使得位于双螺纹杆两侧的螺纹套筒会同步向中间靠拢,使限位装置在此过程中一直保持在两侧定位装置的中间的位置上,保证单侧接触板先于另一侧接触板与前轮组或后轮组相接触时双螺纹杆在转动的过程中依然能够保持在中间的位置上,避免传统校准工装两侧的定位器采用分体设计并通过测量的方式来确定中间位置会出现误差而导致定位不在正中间的问题,提高了该装置定位的精准性。
