The invention provides a wheel set axis positioning device for wheel set overhauling. The wheel set axis positioning device for wheel set overhauling comprises a frame, a horizontal reinforcing rib isarranged in the middle of the frame, a positioning element is arranged at the center of the reinforcing rib, an upper clamping part and a lower clamping part are symmetrically arranged in the frame of the upper and lower portions of the positioning member, and structures of the upper clamping part and the lower clamping part are the same. The upper clamping part comprises supporting plates, two clamping members are correspondingly arranged on the opposite surfaces of the two supporting plates close to the wheel set direction, the clamping members on the supporting plates are symmetrically distributed with respect to an extension line of the positioning member shaft axis, the upper clamping part and the lower clamping part are correspondingly connected with a driving member, and the driving member can drive the upper clamping part and the lower clamping part to move oppositely or contradictorily. The wheel set axis positioning device for wheel set overhauling can position the wheel setaxis through the clamping parts arranged oppositely, the driving member can drive the clamping parts to move oppositely or contradictorily, the synchronicity is good, the driving member is matched with an electromagnetic, and the stability of a system is improved.
Description
technical field [0001] The invention belongs to the technical field of rail transit vehicle wheel set maintenance equipment, and in particular relates to a wheel set axle center positioning device for wheel set maintenance. Background technique [0002] The wheel set of the running part of the railway vehicle is a key component to ensure the safety of the train, and it is also the key to the safe operation of the train. In the various regular maintenance of the vehicle, the maintenance of the wheel set is particularly important. During the wheel set overhaul process, the center of the wheel set needs to be positioned, but due to the different models of the tested wheel set, the size of the supporting journal is also different, which brings a lot of inconvenience to the initial axis center positioning of the wheel set. At present, in order to solve this problem, operators mostly adopt different limit blocks, displacement sensor control and other components, which makes the ma...
