AI Technical Summary
Existing support screws are prone to nut loosening due to vibration during machining, affecting machining accuracy and product quality.
The system employs a combination of a locking spring and a locking nut, along with a floating spring and an adjusting nut. By rotating the locking nut, the elasticity of the locking spring and the supporting effect of the floating spring are adjusted. The system utilizes an inverted conical structure and a limiting groove and limiting pin for clamping and limiting, achieving self-adaptive clamping and stable support.
It improves the locking stability and reliability of the support screw, reduces machining errors caused by loosening, enhances machining accuracy and product quality, has a simple and easy-to-operate structure, and reduces manufacturing costs and ease of use.
