Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gear processing, in particular to a roundness correction tooling for ring gear workpieces. Background Technique
[0002] Induction hardening is a heat treatment method with relatively small deformation. However, the superposition deformation of quenching structure stress, thermal stress and machining stress in the teeth of thin-walled large parts still has a great impact on the subsequent processing of the parts. After induction hardening of the teeth, there are thermal stress and structure stress, plus the superposition of machining stress during subsequent grinding of the tooth roots, resulting in elliptical deformation of the thin-walled ring gear. After the elliptical deformation exceeds a certain value, the parts cannot be subjected to subsequent gear grinding processing and must be subjected to roundness correction.
[0003] However, most of the existing workpieces use the form of internal expansion rings to physically correct the roundness of the ring gear, which has the problems of poor internal stress elimination effect and complex tooling structure. Therefore, a roundness correction tooling for ring gear workpieces is provided to solve the problems raised in the above background technique. Content of the Utility Model
[0004] To make up for the above deficiencies, the utility model provides a roundness correction tooling for ring gear workpieces, aiming to improve the problems of poor internal stress elimination effect and complex tooling structure in the existing technology.

[0006] Further, the pressing component includes a workpiece pressing device, the workpiece pressing device is arranged on the right side of the cylinder, and a long shaft is fixedly installed inside the workpiece pressing device, and the long shaft penetrates through the inside of the ring gear workpiece.
[0007] Further, a detection device is fixedly installed on the front part of the ring gear workpiece.
[0008] Further, a workpiece supporting device is fixedly connected to the right part of the ring gear workpiece.
[0009] The utility model has the following beneficial effects:

The long shaft of the workpiece pressing device passes through the slot hole and extends into the internal part of the toothed ring workpiece, reducing the shaking of the workpiece during downward pressing. The workpiece rotates through a servo motor and a rotating roller shaft. The detection rod of the detection device is placed on the workpiece to detect whether the circular runout of the workpiece is qualified. When the detection result is unqualified, the press head will press down the workpiece, repeating the detection and pressing processes until the additional detection result is qualified.
