Description

With the special main shaft mill of the stone material grinding head of four knife bars

Technical field

The utility model relates to processing of stone machinery field, relate to stone machining equipment, main shaft mill head in concrete and stone machining equipment, be particularly applied to the processing of tombstone surfacing a kind of efficiently, planetary gears is relevant with the main shaft mill head of four knife bars.

Background technology

Even to this day; in stone machining equipment classification; particularly be applied in the lathe classification of the automatic processing of tombstone grinding, mostly adopt single bistrique to carry out grinding, in the time of the large-area block faces of processing; single cutterhead grinding; obviously be that working (machining) efficiency is low, particularly, in the equipment of this class machining center, industry also still adopts single mill at present; show especially many defects, a, processing benefit are not high; B is in order to install or change the convenience of cutterhead, and taking into account again the alignment of shafts is that hollow pipe can pass through the needs of the cooling grinding heat of current.And the removable cutter mechanism in industry is to adopt electromagnet mechanism form at present, when after energising, the electromagnet that is arranged on main axis arbor head produces suction and has held the cutterhead that needs installation, when inhaling after iron power-off, knife bar head suction disappears and throws off mounted cutterhead, to reach the object of Fast Installation or replacing cutterhead.But, there is a fatal hidden danger, if main shaft cutterhead is during High Rotation Speed grinding in above-mentioned this mechanism, the major accident of even hurting sb.'s feelings, likely appears that mill departs from main shaft and flies out, in the suddenly circuit power-off of being out of order, so this mechanism is a kind of unreliable, unsafe removable cutter mechanism.
