Description
Technical field
The present invention relates to engine art, particularly a kind of pre-glue spreading method of joint of pipeline.
Background technique
For guaranteeing the sealing of threaded connection place, when the assembly line of motor is component installation pipeline joint, adopt following two kinds of methods to process:
A kind of is to adopt the method for carrying out artificial gluing in the thread surface of pipe joint.During artificial gluing, need not gluing of termination the first tooth, and keep clean to prevent that glue from entering downstream component and causing secondary pollution, after gluing completes, need immediately pipe joint to be screwed on component and solidify to prevent glue from cruelly leaking overlong time in air.Artificial gluing speed is low, causes efficiency of assembling low; And gluing personnel are difficult to accurately hold the amount of glue, in order to guarantee fully effective sealing, gluing personnel tend to some glue of overbrushing, so not only cause glue waste, and glue just installs before uncured at once, now or fluid state easily pollutes downstream part by thread pitch.In addition, motor needs performance test after completing final assembly, must after glue solidifies completely, just can make a service test, to guarantee the sealing completely of pipe joint, if glue curing overlong time, engine performance test just needs to lag behind, and the manufacturing efficiency of motor reduces; If the glue curing time is shorter, can, because cure shrinkage is violent, be easy to cause shrinkage cavity or cracking and seal failure phenomenon occurs.
Another kind method is raw meal belt to be wrapped in to the thread outer surface of pipe joint before installation, again pipe joint is tightened, compare with artificial gluing, raw meal belt can effectively be avoided the problem of polluting, need to after being wound around raw meal belt, not assemble at once yet, but need to be around good multi-turn while being wound around raw meal belt, and around direction must and the rotation direction of screw thread always, otherwise likely raw meal belt is squeezed and withdrawn while installing, manufacturing efficiency is low, and there have part raw meal belt to be exposed at screw thread outside to be outward very not attractive in appearance.
The information that is disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Summary of the invention
The object of the present invention is to provide a kind of pre-glue spreading method of joint of pipeline, low thereby the screw thread that has overcome butt joint on assembly line carries out the manufacturing efficiency that gluing causes, and the defect that easily downstream component polluted of glue.
For achieving the above object, the invention provides a kind of pre-glue spreading method of joint of pipeline, comprise the steps: after the completion of processing of joint, remove sharp edge, the burr of joint, and check the screw thread of joint and the defect whether sealing surface has cut and collide with; If the screw thread of joint and sealing surface no marking and the defect of colliding with, the surface of cleaning joint; Dry the surface of joint; Pre-cementing on all the other screw threads except the first tooth of joint; Surface to glue is cured, and makes the skin of glue solidify exsiccation, and the internal layer of glue is emulsus; The joint that coats glue is transported to erecting yard and assembles, make the emulsus glue of the internal layer of glue be extruded and be filled in the gap of sealing surface, be formed with flexible sealing strip.
Preferably, in technique scheme, after the surface of glue is cured, protecting cover is installed on joint.
Preferably, in technique scheme, glue is anaerobic adhesive.
Preferably, in technique scheme, the surface cure step of glue is carried out in temperature control box.
