Abstract
The invention provides a machining clamp for bevel gears, belongs to the technical field of machinery, and aims to solve the problem that the conventional machining clamps for bevel gears are poor in clamping effect. The machining clamp for bevel gears comprises a disk-shaped clamping body which is formed by at least three clamping blocks, wherein the clamping blocks are the same in the aspect of size and are distributed like a circular array; clamping holes which are used for clamping bevel gears are formed in the middle parts of the clamping body; each clamping block is provided with a clamping part which protrudes into the clamping hole; the length directions of the clamping parts extend along gear slots of the bevel gears; the clamping parts extend into and lean against corresponding gear slots; guiding structures which are used for guiding the clamping blocks are arranged at the rear end of the clamping body; under the action of the guiding structures, the clamping blocks extend in the radial direction of the clamping body; positioning units which are used for axially positioning the bevel gears are arranged on the guiding structures. The machining clamp for bevel gears has the advantages of being reasonable in structural design and stable in clamping, and the difficulty that the involute tooth surfaces are ultra-poor in runout for machined inner circles is solved.
