AI Technical Summary
Existing grinding equipment has unstable clamping when fixing screwdriver blanks, resulting in reduced grinding accuracy. In particular, the non-parallel state between the plane of the insert end and the line of the bit end causes the bit to be skewed when it contacts the grinding disc, affecting grinding accuracy.
The screwdriver head grinding machine adopts multi-station synchronous grinding. Through the combination design of clamping parts and support blocks, the screwdriver blank is pre-fixed and corrected by the drive unit and locking unit to ensure that the screwdriver blank maintains the accurate angle during the grinding process.
It improves the grinding precision and quality of screwdriver blanks, ensuring that the screwdriver blanks do not rotate during the grinding process, thereby improving grinding efficiency and accuracy.
