AI Technical Summary
In existing technologies, shaft parts require multiple manual positioning steps before processing, which makes it difficult to ensure the central symmetry of the two free ends, resulting in imbalance and affecting processing accuracy and production efficiency.
The component positioning plate and the support base work together to achieve synchronous positioning of the two free ends of the workpiece shaft, ensuring that the two free ends are symmetrically distributed relative to the central axis of the base. Synchronous positioning and clamping are achieved by cylinder drive.
It improves the stability and precision of shaft parts during machining, enhances production efficiency and product quality, and reduces positioning time and displacement deviation.
