Abstract

The invention discloses a gear inner ring interference fit tool clamp. The clamp comprises a rotating shaft seat, a chuck and a pull rod. The chuck and the rotating shaft seat are coaxially and rotatably connected, and three clamping jaws are evenly distributed on the circumference of the chuck; the outer circumferential faces of the clamping jaws are in interference fit with the inner ring of a machined gear, and the pull rod pushes and pulls the center of the chuck to move in the axial direction of the centre of the chuck; and positioning blocks are arranged on the sides of the clamping jaws of the chuck. According to the gear inner ring interference fit tool clamp, the problems that in the prior art, a gear penetrates a mandrel, so that the gear inner ring and the mandrel do not share the central axis, and the gear machining precision is low are solved.

Description

technical field [0001] The invention relates to a fixture for fixing a ring gear, in particular to an interference fit fixture for a gear inner ring. Background technique [0002] The fixture is a device used to fix the processing object in the machining process so that it occupies the correct position to accept construction or inspection. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be a fixture. [0003] The accuracy of the initial processing fixture will be relatively low, and the positioning accuracy of the high-precision fixture will be higher. [0004] In the patent document with the patent number 201410690466.9, a gripper fixture for the finishing of this wheel is disclosed, which includes a fixture head, the left end of the fixture head is a disc fixed base with cylindrical bosses arranged on both sides, and the right end is a threaded Cylindrical main shaft, a disc-shaped backing plate...
