Abstract
The invention discloses a tool change oil cylinder mechanism, which includes a cylinder body, a piston, a first guide ring, a top cover, a gland, an anti-rotation pin and a sealing structure, the piston is movably installed in the inner cavity of the cylinder body, and the first guide ring is arranged Between the piston and the cylinder body, the top cover is set on the piston, the cylinder body is provided with an unloading knife oil inlet and a broach air inlet, the gland is set on the piston, and the gland is located between the top cover and the cylinder body, and the gland passes through The anti-rotation pin is connected with the piston, and the sealing structure is arranged between the piston, the gland and the cylinder body. The invention also discloses the tool change mechanism of the main shaft of the machining center, which includes a shaft core, a broach mechanism, a cutter head and a tool change cylinder mechanism. The core, the cutter disc is set on the broach mechanism and matched with the piston, and the dust blowing and ventilation pipeline is formed between the gland, the piston, the cutter disc and the broach mechanism. The invention can solve technical problems such as oil leakage of the oil cylinder, slow reset of the main shaft, orientation deviation of the main shaft, falling of the tool, dust accumulation of the tool, short service life and the like.
Description
technical field [0001] The invention relates to machine tool equipment of a numerically controlled machining center, in particular to a tool changing oil cylinder mechanism and a tool changing mechanism of a machining center spindle. Background technique [0002] CNC machining center machine tool is a kind of integration of mechanical equipment and CNC system. It is mainly used for industrial manufacturing processing, and is widely used in the processing of parts in aerospace, shipbuilding, automobile, mold, communication and other industries. Efficient automatic processing equipment suitable for complex parts. Its comprehensive processing ability has certain advantages. The workpiece can be clamped to complete multiple processes at one time, so it can effectively improve the processing accuracy and efficiency of parts. [0003] At present, the tool change mechanism of the spindle of the machining center is mainly through the input of hydraulic oil into the tool change cyli...
