In the present embodiment, three eccentricity valve job analysis：
Metal hard-sealing butterfly valve can be divided into single eccentric, double eccentric and three eccentricity structure according to design feature.Single eccentric structure both butterfly plate axis deviation sealing surface, without the effect of torque pretension, frictional force is big, thus seldom uses.Axis deviation sealing surface is formed first bias by double eccentric structures, axis deviation pipeline is centrally formed the 2nd bias, butterfly plate butterfly plate sealing ring after being opened into about 20 degree is separated with sealing surface of seat to reduce friction and improve service life, it is adaptable to positive conical surface seal.Three eccentricity structure had both increased the 3rd bias on double eccentric foundations, and both conical surface centerline dip was in channel centerline, and this structure type both realizes cam effect, and the abrasion of sealing ring and valve base chamber during valve opening and closing is completely eliminated again.Butterfly valve body sealing surface forms multiple angles in space, surfacing is carried out according to conventional manual method, because sealing surface angle is different, one side surfacing is also needed to while by the valve body anglec of rotation, and the welding amount of surfacing is difficult to control, inefficiency, work quality is poor, welding is unstable, and workpiece is scrapped, and serious economic loss is not only brought to enterprise.Mechanical arm can solve above problems completely in the application of inspection field, it may be said that be the milestone of inspection field, be significant.
According to the geometrical property of three-eccentric-butterfly-valve, the sealing surface (surfacing face) of butterfly valve is an inclined plane, is not suitable for built-up welding, therefore, and displacement angle of tumbling is adjusted before welding, compensates solder side luffing angle.Clamping device angle compensation axle center angle is adjusted, remains that valve surfacing position is horizontal, facilitates welding, meet welding process requirement.As shown in the figure.
Robot realizes that displacement is coordinated in linkage with positioner rotation during welding, remains that welding position is in horizontality, robot swing welding.
In the present embodiment, plasma spray flow：
1st, operator is by work piece hoisting to clamping device, by adjusting positioner, clamping device, it is ensured that welding position is in horizontality；
2nd, operator exits and button, and robot runs to welding position, and positioner rotation starts welding；
3rd, after the completion of welding, robot is removed, and facilitates operator's unloading workpiece；
4th, so move in circles work；
5th, the work station needs operative employee 1-2.
