Device and method for machining flywheel assembly

Abstract

The invention discloses a device and a method for machining a flywheel assembly. The whole machining processes are sequentially as follows: a first vertical lathe is used for machining the front surface of a flywheel; a horizontal machining unit is used for performing flywheel signal gear machining; a gear ring heating device is used for heating a gear ring; a press machine is used for carrying out gear ring and flywheel pressing and sleeving; a second vertical lathe is used for machining the working face of the flywheel; a cleaning workbench is used for cleaning the flywheel; an online detection device is used for carrying out online detection on the flywheel; an infrared scanning unit is used for carrying out infrared scanning and positioning on the flywheel; a first vertical machining unit is used for carrying out flywheel hole position machining; a second vertical machining unit is used for carrying out flywheel installation hole machining; a laser marking machine is used for carrying out laser printing of an ignition mark; and dynamic balance equipment is used for carrying out dynamic balancing of the flywheel. According to the device and the method, due to the adoption of a roundabout layout of automatic operation of manipulators, the labor intensity of workers and the number of the workers are greatly reduced, the fact the process capabilities of important sizes of products are all 1.67 or above is ensured, the reject ratio of product machining is remarkably reduced, and the monthly waste loss is reduced by 50% or above.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a processing device and method for a flywheel assembly for a commercial vehicle engine. Background technique [0002] The flywheel is the key starting part of the automobile engine. It is generally a thick disc. Its size, weight and balance performance seriously affect the performance of the engine. Therefore, it has both certain dimensional accuracy requirements and certain dynamic requirements. unbalanced volume requirements. With the improvement of the engine performance requirements of the automobile, the requirements for the schedule and dynamic balance of the flywheel also increase accordingly. [0003] The traditional flywheel assembly consists of a flywheel disc and a flywheel ring gear. The flywheel ring gear is shrunk onto the flywheel disc to form a flywheel ring gear assembly. There are rectangular signal teeth (or peripheral drilling) on ​​the flywh...
