Ball for ball valve surface laser cladding locating mechanism
Technical field
The present invention relates to the valve class, particularly a kind of ball for ball valve surface laser cladding locating mechanism.
Background technology
At present, ball valve has been widely used in various fluids conveyings and chemical technique system, the role of ball valve in these fields is also very important, these fields require more and more higher to ball valve, particularly the ball valve core wear resisting property is had relatively high expectations, existing technology adopts spool face is processed, the surface-treated technology had now is a kind of is to adopt plasma spraying technology, the deficiency that this technology exists is that the bonding force of sprayed coating and spool face is poor, if use for a long time the sprayed coating of spool face to be worn, cause ball valve to leak.
Another kind of technology is to adopt laser melting coating, this technology is that coated material is trickled down on the spheroid of ball valve, through laser irradiation, the coated material cladding is combined in to spherome surface, thereby significantly improve the wear-resisting and anti-corrosion processing method on ball material surface, this technique anchoring strength of coating is good, long service life.The realization of this technology needs the light beam of laser vertical with each point on the spheroid sphere and be positioned at the focal length of laser, in existing this laser melting and coating technique implementation process, need to constantly regulate the position of laser head and spheroid, make the sphere of spheroid be positioned at the laser focal of laser head, this mode working (machining) efficiency is low, and can't ensure that laser beam is vertical with the sphere of spheroid, and cause the spheroid sphere to heat up under lasing uneven, affected the bonding strength of coating.
Summary of the invention
In order to overcome the defect of prior art, the invention provides a kind of ball for ball valve surface laser cladding locating mechanism, locating mechanism purpose of the present invention is to ensure that laser beam is vertical with any point of spherome surface when the cladding of processing spherome surface, simultaneously in the course of processing without the advantage of adjusting laser head.
Technical scheme of the present invention: a kind of ball for ball valve surface laser cladding locating mechanism, it is characterized in that: comprise anchor, turret, the first actuator and the second actuator, and for the fixing stationary installation of spheroid, described turret is provided with rotating shaft, described stationary installation is arranged in rotating shaft, described the first actuator is fixed on turret and with rotating shaft transmission and is connected, described the second actuator is arranged on anchor, and be connected with the mid-way of turret, and power output shaft and the turret of this second actuator are rotatably assorted, the power output shaft of described the second actuator and the first actuator power output shaft quadrature.
Adopt technique scheme, the first actuator and the second actuator make sphere fixing device can carry out the rotation of two vertical direction simultaneously, when carrying out the spherome surface cladding, the light beam that laser head is penetrated is through the centre of sphere of spheroid, the laser beam that just can make laser head send can carry out laser processing to any point on the surface of spheroid, has ensured the quality of spherome surface cladding.
The further setting of the present invention: described stationary installation comprises thread jaw chuck and preset pieces, described thread jaw chuck comprises disk body of chuck and the claw that can radially slide on disk body of chuck, described claw is provided with the fixture block for the place kick valve sphere, the other end of the relative claw of described fixture block is provided with block, described block and preset pieces removably connect
Adopt above-mentioned further setting, not only convenient installation and fixedly spheroid are set like this, and it is vertical with the sphere any point of spheroid to affect laser beam.
The further setting of the present invention: described rotating shaft comprises the first rotating shaft and second rotating shaft of coaxial rotation, and described thread jaw chuck is arranged in the first rotating shaft, and described preset pieces is arranged in the second rotating shaft.
Adopt above-mentioned further setting, arranging so on the one hand is the setting of being convenient to stationary installation, is the installation and removal of being convenient to spheroid on the other hand.
The further setting of the present invention: described the second rotating shaft comprises second driving shaft and be arranged on the expansion link on second driving shaft, and described preset pieces is arranged on the end of expansion link.
Adopt above-mentioned further setting, arranging of expansion link facilitates sphere installation and dismounting.
The further setting of the present invention: described turret is made as semicircular arc, and the central shaft of described rotating shaft and the central shaft of semicircular arc are arranged on same straight line.
Adopt above-mentioned further setting, setting is not only simple in structure like this, and ensures that laser beam is vertical with the spheroid sphere.
