Technical field
The utility model relates to pipeline outer surface guard technology field, be particularly related to the automatic hot spray apparatus on a kind of pipe fitting surface, be the automatic used for hot spraying cardan (hookes)universal joint chuck on a kind of hot spray apparatus, be applicable to clamping and the transmission when thermal spraying automatically of elongated or collapsible tubes rod workpieces.
Background technology
Adopt the spraying of pipeline outer surface heat, can play pre-corrosion-resisting function pipeline.When elongated or yielding pipe fitting shows automatic thermal spraying,, can produce and beat because pipe fitting exists certain amount of deflection or distortion; Because hot spray apparatus is subjected to the restriction of axial dimension automatically, when the drift angle is big, single universal joint can not make output shaft equate with the instantaneous angular velocity of power shaft, cause vibration easily, the damage of aggravation parts, and produce very big noise, and make the driving shaft of automatic hot spray apparatus and workpiece centre axle not on same straight line, there are certain included angle and distance.When the spray gun on the walking dolly that is fixed on automatic hot spray apparatus during with certain speed and direction rectilinear motion, will cause the coating layer thickness on the surperficial diverse location of same section workpiece inhomogeneous, have a strong impact on coating quality.
The utility model content
The purpose of this utility model is: a kind of automatic used for hot spraying cardan (hookes)universal joint chuck is provided, can block firm workpiece end, even workpiece has slight deformation or swing, the cardan (hookes)universal joint chuck can be adjusted thereupon, guarantee that the thickness of hot-spraying coating is even on the same cross-sectional, guarantee the thermal spraying quality.
The technical solution adopted in the utility model is: automatic used for hot spraying cardan (hookes)universal joint chuck, main driving shaft, rolling bearing pedestal, power transmission shaft adapter sleeve, universal coupling with spider, chuck connecting plate and scroll chuck are formed.On the driving shaft outer wall rolling bearing is arranged, rolling bearing is in rolling bearing pedestal, it is characterized in that: the clutch end at driving shaft has the power transmission shaft adapter sleeve, the end of power transmission shaft adapter sleeve is fixed with universal coupling with spider, be connected with the chuck connecting plate in the end of universal coupling with spider, the chuck connecting plate connects scroll chuck by bolt.
Scroll chuck can self-centering, can clip by the thermal spraying workpiece end.
Described universal coupling with spider connects joint by cross axle, cross and pivot pin is formed.
The other end at tubular power transmission shaft adapter sleeve has groove, inserts the parallel protruding block of cross axle one end in the groove of power transmission shaft adapter sleeve end.The hole on vertical cross axle protruding block plane is arranged on the end of power transmission shaft adapter sleeve and cross axle protruding block, pivot pin is arranged in the hole.In the middle of the cross axle is cylinder, and having at cylindrical two ends cross section is arranged respectively is the protruding block of rectangle, and two protruding blocks are vertical mutually, and the hole of a vertical protrusion piece is arranged respectively on two protruding blocks.The parallel protruding block of the cross axle other end inserts cross and connects in the groove that saves the end.The parallel protruding block of the cross axle other end is connected the hole that there is vertical cross axle protruding block plane the end of saving with cross, pivot pin is arranged in the hole.The parallel protruding block that cross connects the joint other end inserts in the groove of chuck connecting plate end bosses axle.The parallel protruding block that cross connects the joint other end has vertical cross to be connected the hole on joint protruding block plane with chuck connecting plate end bosses axle, and pivot pin is arranged in the hole.
Power transmission shaft adapter sleeve, cross axle, cross connect joint and the chuck connecting plate is equipped with positioning through hole, connects by the pivot pin assembling, is implemented in freely rotating on a certain direction.By Bolt Connection, guarantee to connect fastening and concentric between driving shaft and the power transmission shaft adapter sleeve.Scroll chuck connects with the chuck connecting plate by bolt, guarantees to connect fastening, concentric.
Automatic used for hot spraying cardan (hookes)universal joint chuck principle: consult Fig. 1.When elongated or the automatic thermal spraying of collapsible tubes rod workpieces, at first workpiece is clipped the end of workpiece by chuck 9, chuck 9 has the self-centering function, can guarantee that workpiece is concentric with chuck 9.Then, connected with driving shaft 1 by the cardan (hookes)universal joint chuck by the spraying workpiece, when driving shaft 1 rotates, chuck 9 and workpiece are not only with driving shaft 1 uniform rotation, and can swing in any direction with cross axle 6 centers, the needs that angle and distance change have simultaneously been adapted to, smooth transfer moment of torsion, the quality of assurance workpiece thermal spraying.
Connect by bolt 3 between driving shaft 1 and the power transmission shaft adapter sleeve 4, guarantee to connect fastening and concentric.By Bolt Connection, guarantee to connect fastening, concentric between scroll chuck 9 and the chuck connecting plate.Power transmission shaft adapter sleeve 4, cross axle 6, cross connect joint 7 and chuck connecting plate 8 all assembles connection mutually by pivot pin 5, thereby is implemented in freely rotating on a certain direction.
Near driving shaft 1 one sides cross axle 6 is being installed, cross connection joint 7 is being installed near a side of scroll chuck 9.Because amount of deflection or distortion produce when beating, and cardan (hookes)universal joint will be regulated automatically, the angle at assurance driving shaft 1 and workpiece two ends equates, guarantees that driving shaft 1 equates all the time with the instantaneous angular velocity of workpiece when workpiece, and running steadily, efficiently.
The beneficial effects of the utility model: used for hot spraying cardan (hookes)universal joint chuck has following effect automatically:
1, a kind of automatic used for hot spraying cardan (hookes)universal joint chuck structure is simple, reasonable, compact.
2, a kind of automatic used for hot spraying cardan (hookes)universal joint chuck has automatic regulatory function, guarantees that the angle at driving shaft and quilt spraying workpiece two ends equates, guarantee that driving shaft equates all the time with the instantaneous angular velocity of workpiece, running steadily, efficiently.
3, automatically during thermal spraying, even workpiece has slight deformation or swing, the cardan (hookes)universal joint chuck can be adjusted thereupon, guarantees that the thickness of hot-spraying coating is even on the same cross-sectional, guarantees the thermal spraying quality.
