Abstract
The invention discloses a milling tool for milling a circumferential key groove in an output shaft, and relates to milling tools. The milling tool solves the problems that when a circumferential key groove is milled in an existing output shaft, the rejection rate is high, economic losses are caused, and the whole product delivery time is seriously affected. A positioning shaft comprises two levels of stepped shafts, namely the first-level stepped shaft and the second-level stepped shaft from bottom to top in sequence. External threads are arranged on the outer side wall of the second-level stepped shaft. The diameter of the second-level stepped shaft is smaller than that of the first-level stepped shaft. An inner through hole is formed in a connecting cap. The inner through hole is internally provided with internal threads matched with the external threads on the outer side wall of the second-level stepped shaft. The connecting cap is connected with the upper portion of the positioning shaft through the external threads and the internal threads. According to the milling tool, due to the fact that a workpiece is accurately positioned, the angular position of the workpiece does not need to be aligned every time, the labor intensity of a worker is reduced, the machining efficiency is improved by 20% to 23%, economic losses are reduced, and meanwhile the product delivery time is effectively ensured. The milling tool is used for milling the circumferential key groove in the output shaft.
