Bar is located at beside fixed guide rail and relatively fixed with fixed guide rail, the output end of the second electric pushrod and one of side of bottom plate
Face is hinged, and the second electric pushrod pushes bottom plate along fixed guide rail sliding.
The end of fixed guide rail is equipped with limited block.Limited block is located at wherein one end of fixed guide rail, and the second electric pushrod leans on
The other end of nearly fixed guide rail, the ontology of the second electric pushrod and fixed guide rail are relatively fixed, the push rod of the second electric pushrod with
Fixed guide rail is parallel.Limited block prevents the second electric pushrod when adjusting spray distance beyond fixed guide rail stroke.
Motor, the first electric pushrod, the second electric pushrod are electrical connected with control system.Motor, the first electric pushrod,
The control mode of second electric pushrod is the prior art.
The working principle of this spray head regulating mechanism: when needing to adjust spray angle, start motor, motor passes through two
The engagement of a bevel gear drives turntable to rotate indirectly, and turntable drives the spray head of driving assembly to rotate around bottom plate by connecting rod, real
The adjusting of existing spray angle, spray head spray angle can exist according to laser pen from obtaining spray head to heart function during adjusting
Eject position on workpiece can determine whether the spray angle of adjusting has been adjusted in the reading of dial according to pointer
Suitable spray angle is adjusted to after suitable spray angle, motor stalls, while the first electric pushrod rapidly will friction
Piece is released, and the circumference side of friction plate and turntable rubs, and turntable stops operating at once.First electric pushrod and friction plate are spraying
Turntable is locked after the completion of angular adjustment, guarantees the injection stationarity of spray head in process in spray head sleeve.When
When needing to adjust spray distance, such as when need to process different dimension workpieces or when clamping workpiece, at this time
Two electric pushrods drive bottom plate along fixed guide rail sliding, and bottom plate drives nozzle component mobile, realizes the adjusting of spray distance.Spray
Can use laser pen during head spray distance adjusting measures current spray distance.
