Description
Technical Field
The utility model relates to the technical field of machine tool fixtures, in particular to a fixed non-falling axle box fixture in a turning lathe.
Background
Wheel set axle boxes in rail transit vehicles can be clearly divided into two main types of inner axle boxes and outer axle boxes according to the design positions and the functional characteristics of the wheel set axle boxes. These two axle boxes play a critical role in supporting the wheels, transmitting traction and bearing the various loads in the train operation. In particular, the accuracy and safety of this process is particularly critical when performing periodic turning operations on the inner axle box wheel set.
At present, a wheel lathe which is used for turning and repairing the wheel set tread of a domestic rail transit vehicle does not fall down, and a mode of fixing an outer axle box is generally adopted for clamping the wheel set. At present, there is no external axle box at home and abroad, only the vehicle type with the internal axle box exists, and the turning repair of the vehicle type of the internal axle box on the existing non-falling wheel lathe is a technical problem to be solved. During the turning process, the friction wheel of the lathe can precisely act on the wheel set, and the wheel set is jacked to a preset position by applying upward jacking force. This process ensures that the wheel set can be moved out of direct contact with the rail, creating conditions for subsequent machining operations. Meanwhile, in order to maintain the stability and stress balance of the wheel set during machining, the lathe bed must take action simultaneously. Specifically, the bed body is firmly gripped by a specially made clamping jig on the inner axle box portion of the train wheel set and a downward pulling force is applied. The tension and the upward pushing force provided by the friction wheel form a pair of balance forces, so that any accidental movement or shaking of the wheel set in the machining process can be effectively prevented, and the machining precision is ensured. Therefore, the special clamping fixture is important for turning and repairing the wheel set.
