Abstract

The invention belongs to the field of lathe auxiliary machining equipment, and particularly relates to slender shaft auxiliary machining equipment for a numerically controlled lathe. The slender shaftcomprises a base, a sliding seat, a screw rod A, an arc-shaped bracket, a support seat B, a T-shaped guide block, a shaft B, telescopic rod mechanisms A and telescopic rod mechanisms B, wherein the base is arranged on a machine tool body; and the sliding seat is in sliding fit with the interior of a sliding groove A in the base in the direction perpendicular to the slender shaft. In a turning process of the slender shaft, the two telescopic rod mechanisms A and the multiple telescopic rod mechanisms B are used for pressing the slender shaft in a staggered mode at a certain angle to prevent the slender shaft from being bent by a turning tool. Moreover, the slender shaft does not need to be repeatedly clamped for multiple times in an auxiliary slender shaft machining process, machining errors caused by repeated clamping in the slender shaft machining process are avoided, and machining precision and machining efficiency of the slender shaft are effectively improved.

Description

technical field [0001] The invention belongs to the field of lathe processing auxiliary equipment, and in particular relates to a slender shaft processing auxiliary equipment for a numerically controlled lathe. Background technique [0002] A shaft with a ratio of length to diameter greater than 25 (ie L / D>25) is called a slender shaft. The traditional processing of the outer circular surface of the slender shaft has the problem that it is not easy to clamp. When processing the outer circular surface of the slender shaft, the radial pressure generated by the turning tool on the slender shaft makes the slender shaft bend. As a result, the processing parameters of the slender shaft are wrong. The general method of processing the slender shaft is to gradually protrude the slender shaft from the clamping hole on the main shaft seat, and process the slender shaft section by section. At the same time, the tailstock supports the processed slender shaft to improve the The relat...
