Quantitative gluing device for automobile engine cover

The utility model relates to the technical field of automobile maintenance, in particular to a quantitative gluing device for an automobile engine hood, which comprises a barrel and a quantitative box, an injection tube head is arranged at the front end of the barrel, a slidable piston rod is inserted into the barrel, and a piston is arranged at the end, located on the inner side of the barrel, ofthe piston rod. Wherein a storage chamber is reserved in the quantifying box, an inlet and an outlet are formed in the top of the storage chamber, a rotatable quantifying barrel is arranged at the lower half part of the storage chamber, a plurality of quantifying chambers which are circumferentially distributed are formed in the barrel body of the quantifying barrel, the structures of the quantifying chambers are the same, and the storage chamber is communicated with the barrel body; the gluing device solves the problems that the gluing amount of the automobile engine hood cannot be quantitatively controlled and the
