Description

Technical Field

[0001] The utility model relates to the technical field of gear ring processing, in particular to a gear ring inner side drilling device. Background Art

[0002] The flywheel has a large moment of inertia. Since the work done by each cylinder of the engine is discontinuous, the engine speed also changes. When the engine speed increases, the kinetic energy of the flywheel increases and the energy is stored; when the engine speed decreases, the kinetic energy of the flywheel decreases and the energy is released. The flywheel can be used to reduce the speed fluctuation during the operation of the engine. The flywheel is generally composed of a flywheel base, a gear ring, a clutch locating pin and a bearing. When processing the gear ring, a circle of equally spaced mounting holes needs to be processed on its inner side. The existing processing fixture requires manual adjustment by personnel. At the same time, since the sizes of flywheels used in different cars are different, a set of gear ring processing fixtures can only process the gear rings used with it. When processing different gear rings, the corresponding fixture needs to be replaced, which increases the workload, and it is easy to bump during the replacement process, causing damage to the fixture. Therefore, a gear ring inner drilling device is needed to solve the above problems. Utility Model Content
