Positioning device for production and processing of signal tooth flywheel

Abstract

The invention discloses a positioning device for the production and processing of a signal tooth flywheel. The positioning device comprises a machine table, a motor is fixedly mounted at the bottom ofthe horizontal end of the machine table, a driving shaft is rotatably connected with the output end of the motor, a storing plate and a supporting plate are fixedly mounted on the outer surface wallof the driving shaft from top to bottom, and a positioning screw rod is fixedly mounted at the top of the storing plate. According to the positioning device for the production and processing of the signal tooth flywheel, the flywheel is placed on the storing plate, initial positioning of the flywheel is achieved by rotating a positioning block, meanwhile, the top of the flywheel is connected withan electromagnetic block on the supporting plate in a propped mode to control the electromagnetic block to be powered on, the electromagnetic block produces magnetic force to absorb the flywheel, themotor drives the storing plate and the supporting plate to rotate synchronously through an output shaft, the magnetic suction block is matched with the storing plate, the supporting surface and the supporting way of the flywheel are increased, the offset of the flywheel is avoided accordingly, and the positioning accuracy of the positioning device for the production and processing of the signal tooth flywheel is improved.

Description

technical field [0001] The invention relates to the technical field of flywheel processing, in particular to a positioning device for production and processing of flywheels with signal teeth. Background technique [0002] Flywheel, a disk-shaped part with a high moment of inertia, acts like an energy store. For a four-stroke engine, work is done every four piston strokes, that is, only the power stroke does work, and the three strokes of exhaust, intake and compression all consume work. Therefore, the torque output by the crankshaft changes periodically, and the crankshaft speed is also unstable. In order to improve this situation, a flywheel is installed at the rear end of the crankshaft. [0003] At present, there are still some deficiencies in the existing positioning devices for the production and processing of flywheels with signal teeth. First, the positioning effect of the existing positioning devices for production and processing of flywheels with signal teeth is p...
