Description

Knife handle connecting mechanism capable of being rapidly clamped

Technical Field

The utility model relates to a cutter equipment field specifically is a handle of a knife coupling mechanism of quick clamping.

Background

The HSK tool shank is a shank of a tool for high-speed cutting application, and becomes an important link of a machining manufacturing technology in high-speed cutting processing. In the process of positioning and clamping the HSK tool shank, the positioning surface of the tool bar is tightly attached to the main shaft of the equipment, and any gap influencing the precision does not exist. The higher system rigidity and dynamic balance also cause the interference fit between the positioning surface of the cutter bar and the main shaft of the equipment to be needed under the condition that the cutter bar is clamped by the clamping mechanism.

The existing knife handle connecting mechanism is complex in structure and inconvenient to clamp the knife handle, so that the knife handle connecting mechanism which is simple in structure and convenient to clamp the knife handle and can be used for quickly clamping the knife handle is urgently required to be developed aiming at the current situation so as to overcome the defects in the current practical application and meet the current requirements.
