Abstract: A press-mounting and dismounting machine for multi-gauge and multi-type wheel sets, includes: a frame, a wheel set mounting and dismounting mechanism, and a detection mechanism. The frame includes a base, a first column, a second column and a beam. The wheel set mounting and dismounting mechanism includes a first press-mounting device, a second press-mounting device, a movable baffle device, and a synchronous belt transmission device. The first press-mounting device is arranged on the first column, and the second press-mounting device is arranged on the second column. The synchronous belt transmission device is connected with the movable baffle device to drive the movable baffle device to move in a horizontal direction of the base. The detection mechanism includes a driving rotating device and a data detection device, so as to realize accuracy test of wheel set press-mounting.

Abstract: An online high-precision measuring device for full-size parameters of a wheel set of a rail transit vehicle, includes: a first laser sensor, a second laser sensor, a third laser sensor, and a polygon measuring module that are configured to measure multiple parts of the wheel set. The first laser sensor is arranged on an inner side of a track at a certain angle. The second laser sensor is arranged below the track at a certain angle. The third laser sensor is arranged on an outer side of the track at a certain angle. The polygon measuring module is butted with the track. The device can realize online pass-through non-stop measurement of the full-size parameters of the wheel set of the rail transit train accurately, such as tread wear, equivalent conicity and wheel polygon.

Abstract: A finishing boring machine for a high-precision wheel hub hole, includes: a boring machine body, a hydraulic automatic centering fixture, a computer numerical control (CNC) vertical sliding table, a spindle box, a CNC facing head, a cutter assembly, and a hydraulic system. The boring machine body is a main structure of the finishing boring machine for the wheel hub hole. The hydraulic automatic centering fixture is configured to place a to-be-processed workpiece, and is arranged on the boring machine body. The CNC vertical sliding table is configured to control operation of the CNC facing head, and is arranged on the boring machine body. The spindle box is configured to control an operation speed of the CNC facing head, and is arranged on the CNC vertical sliding table. The CNC facing head is configured to control the cutter assembly to process the to-be-processed workpiece, and is arranged on the spindle box.
