The invention discloses a main shaft device with a cooling water channel and a flushing water channel, which belongs to the technical field of machining centers. The main shaft device of the existing machining center has the defects that the cooling effect is not good during the machining process and iron filings are easily entered into the inner cavity of the main shaft when the tool is changed. The invention includes a hollow main shaft and a broach rod, a broach claw, a butterfly spring group and a distributor installed in the inner cavity of the main shaft. The cooling water channel and the flushing water channel are formed through the mutual cooperation of the broach rod and the distributor. When the main shaft During processing, the tool is in a tight state, and the cooling water channel cools the tool at the center, which effectively improves the cooling effect; when the spindle changes the tool, the tool is in a loose state, and the chip flushing water channel flushes the chip at the front end of the spindle cavity to prevent iron Chips enter the interior of the main shaft, saving time for cleaning iron filings, improving work efficiency and prolonging the service life of the main shaft device.
Description
technical field [0001] The invention belongs to the technical field of machining centers, and in particular relates to a spindle device having both a cooling water channel and a flushing water channel. Background technique [0002] During the work of various machining centers on the workpiece, the spindle device of the machine tool usually uses cooling water to cool the tool and the workpiece. The main shaft device generally includes a hollow main shaft, a broaching rod, a broaching claw and a butterfly spring group. The butterfly spring group, a broaching claw and a broaching rod are accommodated in the hollow inner cavity of the main shaft, and the broaching claw is set on the broaching rod At the front end, a broach claw sleeve is fixed between the broach claw and the inner wall of the front end of the main shaft. The butterfly spring assembly is set on the second half of the broach rod. When the machine tool is working, the main shaft is equipped with more and more compl...
