High-speed universal milling head

Abstract

A high-speed universal milling head comprises a taper shank, a locking flange, an upper box body, a lower box body, a spindle box body, a spindle component, a transmission mechanism, a milling head fixing mechanism, a C-axis manual indexing locking mechanism, an A-axis manual indexing locking mechanism, a milling head spindle cooling mechanism and a sealing mechanism, the milling head fixing mechanism comprises a milling head body, locking rivets, a locking flange and a rivet seat, the locking flange is provided with a plurality of locking rivets, the locking flange is connected with the rivetseat installed on a machine tool spindle through the multiple locking rivets, and the milling head body is tensioned and fixed on the machine tool spindle through the locking rivets by the rivet seat. The high-speed universal milling head integrates the advantages of various accessory heads, is high in structural integration, expands the machining range of a machine tool, solves the problem thatconventional accessory heads cannot perform high-speed multi-angle machining and fills the blank in the field of machine tool accessory heads in China.

Description

technical field [0001] The invention relates to an automatic machine tool accessory, in particular to a high-speed universal milling head. Background technique [0002] With the development of science and technology, numerical control technology has been widely used. Among them, the newly developed high-speed cutting technology is the most important advanced manufacturing technology in modern machinery manufacturing. It is an advanced manufacturing technology integrating high efficiency, high quality and low consumption. A series of problems that have been plagued by conventional cutting have been solved by the application of high-speed cutting. Compared with the traditional cutting process, its cutting speed and feed speed are increased exponentially, and the cutting mechanism has also undergone fundamental changes. Compared with traditional cutting, high-speed cutting has undergone an essential leap. The metal removal rate per unit power has increased by 30% to 40%, the c...

Problems solved by technology

At present, domestic machine tool accessories, whether it is a right-angle milling head or a corner milling head, are subject to the limit of the linear speed of the gear and the high temperature caused by high-speed rotation, the maximum speed it can withstand cannot meet the minimum speed requirements of high-speed machining technology, especially For workpieces that need to enter deep cavities and boxes for multi-angle processing, the existing machine tool attachment heads cannot meet their processing requirements
