AI Technical Summary
The existing tip structure blocks the workpiece head position when it holds the workpiece head, making it impossible to grind the outer circle and tip of the workpiece head.
A female head is designed, including a positioning block, a main body block and a connecting block. The positioning block is provided with a second notch and a clearance groove. The first notch has a conical cross-section. The connecting block is fixed to the drive end of the external cylindrical grinding machine to ensure that the workpiece head can pass through and be ground.
It achieves the ability to hold the workpiece head in place without obstructing its position, and can grind the outer diameter and tip of the workpiece head.
