AI Technical Summary
When fine-tuning existing milling cutter heads, it is difficult to ensure the longitudinal position stability of the milling cutter blocks, resulting in low fine-tuning accuracy, especially when adjusting laterally, displacement is prone to occur.
The design employs a wedge block and locking groove. The wedge block engages with the milling cutter block through the inclined locking groove and guide slope, enabling longitudinal fine-tuning of the milling cutter block. Lateral displacement is prevented through the sliding engagement of the serrated groove. Combined with the structure of the locking bolt and connecting hole, the precise adjustment of the milling cutter block is ensured.
This improves the longitudinal fine-tuning accuracy of the milling cutter block, prevents lateral displacement, and ensures the position adjustment accuracy and stability of the milling cutter block.
