Abstract
This utility model discloses a tapping device for machining external threads, relating to the field of machining equipment technology. It includes a tapping lathe, a rod-shaped workpiece, and a tapping device. The tapping device comprises an external spline shaft, an internal spline shaft, and a die. When machining external threads, the tapping device provided by this utility model only requires controlling the rotation direction of the lathe spindle to complete the tapping operation, resulting in low labor intensity. Because a standard die is used for thread machining, repeated tool setting is unnecessary after changing workpieces, and the consistency of batch processing is significantly better than traditional methods, improving processing efficiency. This device is simple to manufacture and readily available.
