The utility model relates to the field of jig, in particular to a detachable claw gear hobbing fixture, which comprises a core shaft of three stages of a ladder shaft, which is divided into a connection section, an installation section and a socket section. A finite position section is set on the connection section, a threaded hole is set on the limit section, and the diameter of the connection section gradually gradually comes from the end of the connecting segment to the limit section. Increasing, the gears to be processed are connected to the installation section, and the socket section is set with a threaded section; the holding claw is set with a sinking hole, the sinker and the threaded hole are matched; the bolts and bolts pass through the screw hole and the sinker, the limit section and the holding claw are connected; the pressure plate and the press plate are the bow plate, the two ends of the press plate are set with the buckle part, the buckle Department buckled and pressed. When the gear to be processed is far away from the end face of the clamping part, the diameter of the pinch part is equal to the diameter of the clamping part, and the gasket is sheathed in the connecting part of the core shaft. The nut is pressed through the thread to compress the washer on the pressing plate, and then the pressure plate is fastened to the gear to be processed. It is convenient to replace worn parts and reduce processing difficulty and production cost.

可拆卸夹持爪滚齿工装夹具
本技术涉及一种夹具,特别是可拆卸夹持爪滚齿工装夹具。
技术介绍
齿轮属于传动机械原件,可以通过轮齿的相互啮合,起到传动的目的,其传动效率高,平稳,因此被大量应用在各种传动的场合,部分齿轮为腹板齿轮,腹板一直延伸到齿轮的基圆的位置,由于腹板的轴向端面低于齿轮的轴向端面,因此在滚齿过程带加工齿轮只能通过对基圆附件的端面进行固定夹持。现有技术中工装夹具为一体的结构,不易于加工,且维护困难。
技术实现思路
针对现有技术存在的问题,本技术的专利技术目的在于提供一种能牢固固定待加工齿轮,方便加工,便于维护的可拆卸夹持爪工装夹具。为了实现上述目的,本技术采用的技术方案为:可拆卸夹持爪滚齿工装夹具包括:芯轴,所述芯轴为三段阶梯轴结构,所述芯轴分为连接段、安装段和套接段,所述连接段上设置有限位段,所述限位段上设置有螺纹孔,所述连接段的直径从连接段端面到所述限位段依次逐渐增大,待加工齿轮套接在所述安装段上,所述套接段上设置有螺纹段;夹持爪,所述夹持爪上设置有沉孔,所述沉孔与所述螺纹孔相配合;螺栓,所述螺栓穿过所述螺纹孔和沉孔,连接所述限位段与夹持爪;压板,所述压板为弓形压板,所述压板两端设置有扣压部,所述扣压部扣压住所述待加工齿轮远离所述夹持部一端的端面,所述扣压部处的直径与所述夹持部处的直径相等;垫圈;垫圈套接在所述芯轴套接段。螺母,所述螺母通过与所述螺纹配合,将所述垫圈压紧在所述压板上,再将所述压板扣紧在所述待加工齿轮上,所述连接段的直径从连接段端面到所述限位段依次逐渐增大,可以避免在滚齿过程中滚齿设备与芯轴发生干涉,通过螺栓将所述夹持爪安装在所述限位段 ...
