The utility model discloses a protective cover for safe
machining of
mechanical equipment, and relates to the technical field of protective covers. The cover comprises a cover body, a
scrap collecting box, a first functional side plate and a second functional side plate, fixing assemblies fixed to a
machining table are symmetrically fixed to the two sides of the cover body, and reserved grooves for installing the first functional side plate and the second functional side plate are formed in the two sides of the cover body respectively. According to the
saw dust collecting device for the sawing
machine, the cover body is arranged to cover the
machining table of the sawing
machine to play a role in safety protection for a user, and the chipping collecting cover, the negative pressure feeding pump, the negative pressure cover and the chipping collecting bag are matched with one another to play a role in collecting
saw dust chippings thrown out in the
machining process; and in consideration of the situation that a small saw is held by hand and a large saw is fixed on the sawing
machine machining table, the anti-
cutting glove and the anti-
cutting telescopic sleeve on the first functional side plate enable the machining personnel to sleeve the hand in the anti-
cutting glove and the anti-cutting telescopic sleeve, and then the anti-cutting glove abuts against the interior of the cover body to hold the handheld small saw for machining.
