Abstract

The invention discloses a conical hole type gear hydraulic clamp. The conical hole type gear hydraulic clamp comprises a pull rod, an upper pressing cover, a lower support, a conical sleeve, a compression spring, a clamp body, a base partly connected with a machine tool and a connecting rod. According to the clamp, elastic force of the compression spring is used for ejecting the conical sleeve upwards, the outer conical face of the conical sleeve and the inner conical wall of the workpiece are in tight contact, workpiece centering is achieved, according to the clamp, the lower support is attached to the lower end face of the workpiece, positioning of the workpiece in the machine tool Z direction is achieved, the connecting rod is used for outputting hydraulic force of the machine tool, through the pull rod, the hydraulic force is transmitted to the upper pressing cover, according to the clamp, the feature that the end face of the lower support is perpendicular to the Z-direction centerline of the clamp is used, the aim that the workpiece is clamped without deflection is achieved, the problems of slow manual clamping and dismounting, and unstable manual clamp positioning precisionin procedures of hobbing, chamfering, gear shaping and gear grinding of a conical hole structure gear can be solved, the machining quality is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machining fixtures, in particular to a hydraulic fixture for tapered hole gears. Background technique [0002] There are various types and specifications of gears in automobile transmissions. The common ones are cylindrical holes, but the tapered holes are rare. In the process of automobile production, it is necessary to process a national VI engine air compressor gear in batches. The gear has a 1:5 taper hole. The existing technology has been manually pressed. This will cause the existing gear manufacturers to face the problems of unstable clamping accuracy, difficult control of product quality, and low clamping efficiency when hobbing, chamfering, gear shaping, and grinding gears with tapered hole structures. [0003] Therefore, it is urgent to design a hydraulic fixture with high precision, strong stability and convenient clamping to improve clamping accuracy, clamping efficiency and product quality. ...
