The development of a coaxial correction device for workpiece clamping is briefly discussed

Abstract To quickly locate and improve the coaxiality of workpieces during the machining process of a common lathe, a coaxiality correction device for mounting workpieces is proposed. This device is mainly aimed at short-shaft workpieces that require multiple mounting operations during the utilization of a common lathe in emergency repair or small-batch production scenarios, which takes up a lot of time and affects the repair and processing efficiency. When using the device developed in this study to correct the coaxiality of workpieces (by making the outer surface of the workpiece tightly fit the outer surface of the bearing assembly until the bearing assembly has difficulty rotating, indicating that the workpiece has quickly aligned), not only can the coaxiality of the machined workpiece be guaranteed, but also the processing efficiency of the workpiece can be effectively improved.
