Abstract

The invention relates to a floating clamping drive device for a hobbing gear. The floating clamping drive device comprises a base, a clamp body arranged on the base, a wedge-shaped clamping unit arranged in the clamp body and used for clamping a workpiece, a first tip and a second tip, wherein the first tip and the second tip which are used for abutting against the two ends of the workpiece are correspondingly arranged at the axes of the two ends of the workpiece. A cone hole is formed in the axis of the clamp body along the axis. The second tip is matched with the cone hole and is fixedly connected into the clamp body. The floating function is achieved when an oblique wedge unit is used for clamping, and the clamping and positioning interference in the clamping process are lowered effectively. Compared with the prior art, the floating clamping drive device has the beneficial effects of being high in product clamping accuracy, reliable in clamping effect and capable of being suitable for automatic feeding and discharging.

Description

technical field [0001] The invention relates to the technical field of gear hobbing, in particular to a floating clamping driving device for gear hobbing. Background technique [0002] Gears are commonly used power transmission components, and are often used to transmit forces in different directions of motion. With the rapid development of the automotive industry, the demand for gears is also increasing. In the production process of the gear, it is necessary to ensure that the workpiece cannot move and rotate independently during the processing, so the positioning of the workpiece is very important. However, the structure of the current positioning device is relatively complicated, and the effect of tightening and positioning is not good, resulting in a relatively high defective rate of hobbing gears. Contents of the invention [0003] The object of the present invention is to provide a floating clamping drive device for gear hobbing with good positioning effect in order...
