AI Technical Summary
Existing bearing clamping devices are prone to slight displacement or deformation during clamping, which can lead to a decrease in machining accuracy, and uneven clamping force may damage the bearing.
The device employs a drive wheel and clamping jaw assembly, which uniformly clamps the inner ring of the bearing through a flexible contact head. The synchronous opening and closing motion of the clamping part is achieved by using a drive motor and gear system. Combined with the through-slot design of the guide rail slider pair and auxiliary plate, it ensures uniform clamping force and no damage.
It achieves stable and damage-free clamping of bearings, improves machining accuracy and the degree of automation of operation, and simplifies the clamping process.
