Abstract

The invention relates to a clamping device of a lathe, and particularly relates to a hobbing clamp for an intermediate shaft. The hobbing clamp comprises a base and a chuck seat, wherein the base is detachably connected with the chuck seat; a through hole is formed in the chuck seat; a mounting sleeve is arranged in the through hole; an elastic sleeve is fixed at one end of the mounting sleeve andadopts a structure with a large upper part and a small lower part; a mounting hole is formed in the base; a tip is arranged in the mounting hole and fixed with the mounting hole in an expansion manner; a groove is formed in one side, connected with the chuck seat, of the base; a connecting seat is arranged in the groove; a pull rod hole is further formed in the base; a pull rod is arranged in thepull rod hole; one end of the pull rod is fixed with the connecting seat; and an avoidance space allowing the connecting seat to move back and forth along the axis of the mounting hole is formed in the groove. The base is not required to be dismounted from the lathe, so that the tip maintenance and replacement efficiency is improved, and the intermediate shaft gear machining efficiency is furtherimproved.

Description

technical field [0001] The invention relates to a clamping device of a lathe, in particular to a hobbing fixture of an intermediate shaft. Background technique [0002] With the continuous development of society, all walks of life are advancing by leaps and bounds. The intermediate shaft is an indispensable part of the automobile gearbox. A gear is integrally arranged on the intermediate shaft. The gear is processed by a hobbing tool. Before processing the gear of the intermediate shaft, the intermediate shaft needs to be fixed on the lathe. Clamp and position the intermediate shaft. [0003] Before the gear machining of the existing intermediate shaft, the positioning of the intermediate shaft is usually achieved by matching the top end with the center hole of the end face of the intermediate shaft, and the intermediate shaft is clamped by the elastic sleeve on the fixture. Due to the traditional intermediate shaft hobbing fixture The top is fixed inside the fixture by bo...
