Description

Technical Field

[0001] The utility model relates to the technical field of gear processing equipment, and particularly relates to a clamping tooling for gear processing. Background Art

[0002] As a mechanical transmission component, gears are widely used in various machinery, such as gear speed reducers and other devices. When gears are processed and manufactured, fixtures are often required to clamp and position them. For example, in the process of milling the center hole of a gear, the fixture is needed to clamp and position the whole gear.

[0003] Traditional gear processing fixtures mainly use three-jaw chucks. When clamping, the three jaws of the three-jaw chuck are used to hold the outer circumference of the gear. Its clamping principle mainly relies on the clamping surface of the jaws to press the gear. However, only relying on this clamping method will cause the gear to be prone to circumferential deflection relative to the fixture during the processing, resulting in deviation in gear processing and reducing the processing quality and accuracy of the gear. Content of the Utility Model

[0029] An arc-shaped hole 31 is opened in the upper part of each first support block 3 in the horizontal direction. The arc-shaped hole 31 is bent away from the axis of the installation disk 2. Each clamping member includes a clamping rod 4 slidably penetrating through the arc-shaped hole 31 on the corresponding first support block 3. The clamping rod 4 is arranged along the radial direction of the installation disk 2. One end of the clamping rod 4 facing the axis of the installation disk 2 is a small-diameter section for fitting into the tooth groove of the gear 8.
