AI Technical Summary

Technical Problem

The existing roughing boring tool has a complex connection structure and insufficient rigidity, making it difficult to meet the requirements of high-speed and high-efficiency chip cutting.

Method used

The design employs a combination of vertical positioning surface and vertical mating surface, as well as inclined positioning surface and inclined mating surface. By using fastening bolts to generate component forces in the horizontal and vertical directions, the locking force is enhanced, thereby improving the connection reliability and overall rigidity between the base and the blade holder.

Benefits of technology

This achieves efficient connection of the roughing boring head, improves the overall rigidity and reliability of the boring head, and meets the requirements of high-speed cutting.

Abstract

The utility model relates to mechanical processing numerical control cutter technical field, especially a positioning locking structure of rough boring head, including main part and blade seat, the top of main part is provided with two seat bodies, and two seat bodies are about the axis of symmetry of main part, the top of each seat body is installed with blade seat, and the blade is installed on each blade seat, and the side of seat body faces another seat body is provided with vertical locating surface, and the top surface of seat body is provided with inclined locating surface, and the bottom of blade seat is provided with vertical cooperation surface and inclined cooperation surface, when assembling, vertical cooperation surface abuts on vertical locating surface, and inclined cooperation surface abuts on inclined locating surface. The utility model's advantage lies in: through vertical locating surface and vertical cooperation surface, inclined locating surface and inclined cooperation surface mutual cooperation, when locking, locking force has component force in horizontal and vertical direction, along with locking force increasing, the connection between seat body and blade seat is more reliable, and integral rigidity also obtains very big promotion.
