A kind of hot spray apparatus of controlled angle of spray
Technical field
The utility model relates to hot a kind of spray equipment, particularly relates to a kind of hot spray apparatus of controlled angle of spray.
Background technology
Plasma spray technology utilizes thermal source to be heated to by sprayed on material dissolve or half melting state, and with certain speed jet deposition to the method forming coating through pretreated matrix surface.Plasma spray technology is on the surface of common material, manufacture a special working surface, it is made to reach: anticorrosion, wear-resisting, antifriction, high temperature resistance, anti-oxidant, heat insulation, insulation, conduction, anti-microwave radiation etc. are several functions, it is made to reach saving material, the object of economize energy, we special working surface coating, manufacturing the method for work of coating thermal spraying.Plasma spray technology is one of important component part of surface process technology, accounts for 1/3rd of surface engineering technology.Angle of spray refers to flame stream axis and by the angle sprayed between surface of the work.When this angle is less than 45 degree, due to the impact of " shadow effect ", coating structure can worsen and form hole, causes coating to be loosened, and in actual process, often runs into the workpiece of different size, need to regulate angle of spray.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of hot spray apparatus of controlled angle of spray
The utility model is achieved by the following technical programs:
A kind of hot spray apparatus of controlled angle of spray, comprise base, be located at the work stage on base, the height-regulating support frame of vertical feet, be located at the lifting platform on height-regulating support frame, the mechanical arm be connected with lifting platform, be located at the shower nozzle of mechanical arm front end and be located at the angle measurement grating sensor of nozzle right side, plasma gas pipe and dusty spray pipe is provided with in described height-regulating support frame, described lifting platform slides up and down along the guide rail be located on bracing frame, automatically controlled rotating shaft is provided with between described mechanical arm and shower nozzle, the measurement laser of described angle measurement grating sensor with flame stream axis being parallel and with flame stream axis and workpiece to be processed surface angulation identical, controller is provided with in described lifting platform, the output of angle measurement grating sensor is connected with controller, described automatically controlled rotating shaft is connected with the control end of controller.
The beneficial effects of the utility model are:
During work, angle measurement grating sensor measures flame stream axis and workpiece to be processed surface angulation, and image data is sent to controller, controller controls electric rotation shaft and regulates nozzle angle, thus ensure that spray angle is suitable for processing, effectively prevent coating structure from worsening and form hole, strengthen anchoring strength of coating.
