Tool changing and air blowing structure for end face of HSK taper hole

Abstract

The invention discloses a tool changing and air blowing structure for an end face of an HSK taper hole. The tool changing and air blowing structure is attached to the taper hole and the end face and comprises main shaft rotors and pull rods, wherein the pull rods are arranged in the main shaft rotors, one end of each pull rod is sleeved with a flow separation cover, an HSK tool holder and an HSK pull claw are arranged at the other end of each pull rod, the HSK tool holders are further arranged on the outer sides of the HSK pull claws, the HSK pull claws can push the HSK tool holders out, and high-pressure air flow can enter from air flow holes in the pull rods and finally is blown out of air blowing holes, thereby achieving the air blowing cleaning function. The tool changing and air blowing structure for the end face of the HSK taper hole is simple in structure, safe and compact, rapid and automatic tool changing of main shafts is guaranteed, the taper hole and the end face are cleaned, meanwhile the high-pressure air flow is prevented from entering a main shaft broach system, the reliability of the main shafts is improved, simultaneous contact positioning of the taper hole and the end face is realized, and the usability of an HSK tool system is ensured.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to an end face knife blowing structure for an HSK taper hole. Background technique [0002] High-speed cutting has become an important part of machining and manufacturing technology. With the development of machining and manufacturing in the direction of high speed, high precision and high production efficiency, the processing performance of the traditional BT tool system has been difficult to meet the requirements of high-speed cutting. 7:24 taper hole has been difficult to meet the requirements. At present, the HSK (German Hohl Shaft Kegel abbreviation) tool system is widely used in high-speed cutting, the KM tool system in the United States, the NC5 and BIG-PLUS tool systems in Japan, etc., all of which are double-sided restraint tool holders. [0003] At present, the 1:10 HSK taper hole is widely used in high-speed cutting. Its main feature is the simultaneous contact pos...

AI Technical Summary

Problems solved by technology

[0004] The HSK tool in the prior art needs to blow and clean the taper hole and the end face when performing automatic tool change, so as to prevent dust or iron filings from entering the pull jaw and the inside of the main shaft and adhering to the taper hole and the end face, but there is no such method The structure can realize the above functions
