The invention discloses a pipeline gluing fixing device, which comprises a supporting underframe, a bearing frame is mounted in the middle of the top of the supporting underframe, a fixing frame is mounted in the middle of the rear end of the supporting underframe, a glue conveying tank is mounted at the top of the fixing frame, a glue feeding plate is mounted at the position, close to bottom, ofthe front end of the glue conveying tank, polishing parts are mounted on the two sides of the fixing frame correspondingly, air cylinders are mounted on the two sides of the supporting underframe correspondingly, push plates are mounted at the opposite ends of the two sets of air cylinders correspondingly, two sets of fixing rods are mounted at the top of the supporting underframe, limiting cylinders are mounted on the inner sides of the fixing rods, a guiding cylinder is mounted on one side of each push plate, a pressing rod is mounted in the mode of penetrating through the top of each guiding cylinder, and each guiding cylinder is internally provided with two sets of oppositely-arranged arc-shaped sheets. An end opening of a pipeline can be polished, meanwhile, a good limiting function is achieved, uniform distribution of glue can be further maintained when the pipeline is glued, and thus the fixing effect is improved.
