Abstract

The invention discloses a clamp for gear milling processing of a signal gear of a vibration reduction belt wheel of an engine crack shaft. The clamp comprises a bottom plate, a pad ring, a compression element and a locking device, wherein the pad ring is arranged on the bottom plate and is used for providing the support for the signal gear; the compression element is used for tightly pressing the signal gear onto the pad ring; the locking device is used for tightly locking the pressing element. The clamp for the gear milling processing of the signal gear of the vibration reduction belt wheel of the engine crack shaft has the advantages that the signal gear is enabled not to become loose during the gear milling processing; the positioning precision is high, so that the processing precision of the signal gear is improved.

Description

technical field [0001] The invention belongs to the technical field of fixtures, in particular, the invention relates to a fixture for engine crankshaft damping pulley signal gear gear milling. Background technique [0002] The signal transmitted by the signal gear on the engine crankshaft damping pulley through the sensor is mainly used to identify the crankshaft speed and position of the automobile engine, control fuel injection and ignition. [0003] At present, when milling the signal gear of the crankshaft damping pulley, because there is no special fixture, the positioning accuracy of the signal gear is low and the signal gear will be loose during the milling process, which seriously affects the processing accuracy of the signal gear. The rework rate of the product is high, and the efficiency of milling gear processing is also affected. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior...
