Abstract

The invention discloses an automatic clamping device for testing the dynamic balance of a flexible flywheel. The device is fixedly installed on a vibrating body of a universal hard supporting balance testing machine, and the flexible flywheel is installed at the top of the device and is clamped by the device. The device is connected with a driving part, and a rotating shaft in the device is driven by the driving part to speed up for dynamic balance testing. The device comprises a rotating main shaft seat, a pull rod, and a rotating main shaft. The rotating main shaft seat is fixed on a rack of the vibrating body, and the pull rod is disposed in a central hole of the rotating main shaft in a sleeved manner through a linear bearing. The rotating main shaft is disposed in the rotating main shaft seat in a sleeved manner through a bearing. The device applies a radial clamping force to the flexible flywheel through radial deformation, effectively avoids the bigger deformation of the flexible flywheel in the axial direction, protects the run-out tolerance of an end face of the flexible flywheel, and improves the dynamic balance testing precision.

Description

technical field

[0001] The invention relates to an automatic clamping device, in particular to an automatic clamping device for dynamic balance testing of a flexible flywheel. Background technique

[0002] The flexible flywheel market is huge and has a bright future. In the mass production process, due to the influence of materials and manufacturing processes, there is an initial imbalance. When a flexible flywheel with excessive unbalance works at high speed, it will cause vibration, noise, shorten life, and even danger to the automobile engine. Therefore, dynamic balance correction must be performed on the flywheel.

[0003] Unbalance measurement is the premise of dynamic balance correction process. To improve efficiency, automatic clamping devices are essential. For flywheel products, clamps are generally used to clamp the flywheel through the inner hole of the flywheel. Flywheel balancing machines on the market often use a pull rod and a single collet as a measuring ...
