The hot spray apparatus of a kind of controlled spray distance and angle of spray
Technical field
The utility model relates to a kind of hot spray apparatus, particularly relates to the hot spray apparatus of a kind of controlled spray distance and 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.Spray gun affects speed when spraying particle and matrix clash into and temperature to the distance of workpiece, and the characteristic sum sprayed on material of coating is very sensitive to spray distance; Spray distance is excessive, and the temperature of powder and speed are all by decline, and adhesion, pore, spray efficiency all can obviously decline too small, matrix temperature rise can be made too high, matrix and coating oxidation, affect the combination of coating.And in actual process, often run into the workpiece of different size, need to regulate spray angle and distance.

Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in the figure, the utility model comprises base 1, the work stage be located on base regulates guide rail 11, be located at the work stage 2 on work stage adjustment guide rail, the height-regulating support frame 3 of vertical feet, be located at the lifting platform 4 on height-regulating support frame, the mechanical arm 5 be connected with lifting platform, be located at the shower nozzle 6 of mechanical arm front end and be located at the grating sensor 7 of nozzle right side, plasma gas pipe 8 and dusty spray pipe 9 is provided with in described support, described lifting platform slides up and down along the guide rail be located on bracing frame, described work stage side is provided with electric pushrod 12, automatically controlled rotating shaft 10 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 grating sensor is connected with controller, described automatically controlled rotating shaft is connected with the control end of controller, described electric pushrod is connected with the control end of controller.
During work, grating sensor measures flame stream axis and workpiece to be processed surface angulation, and image data is sent to controller, and controller controls electric rotation shaft and regulates nozzle angle, thus ensures that spray angle is suitable for processing.
The distance between flame stream and workpiece to be processed surface measured by grating sensor simultaneously, and image data is sent to controller, and controller controls the position of electric pushrod control and regulation work stage, thus adjustment spray distance.
By the effective control to angle of spray and spray distance, prevent coating hole, strengthen anchoring strength of coating, improve spray efficiency simultaneously, prevent coating oxidation.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
