A laser coaxial powder feeding nozzle with adjustable powder convergence point of connecting rod and lever structure

Abstract

A link-lever structured laser coaxial powder-feeding nozzle with an adjustable powder gathering point is characterized in that powder-feeding pipes are arranged outside a cladding head, the powder-feeding pipes are mounted around the cladding head through an angle adjuster that may adjust the included angles between the powder-feeding pipes and the cladding head, each powder-feeding pipe has a downward outlet that is close to a laser outlet, the angle adjuster comprises a sleeve that sleeves the cladding head, one side of the sleeve is provided with a driving device that drives the sleeve to slide up and down along the outer wall of the cladding head, a guiding device is arranged between the sleeve and the cladding head, one end of each powder-feeding pipe close to an inlet is connected to the sleeve through a link, one end of each link is hinged to the corresponding powder-feeding pipe, the other end of each link is hinged to the sleeve, one end of each powder-feeding pipe close to the outlet is hinged to the cladding head, and a central control unit is connected to the driving device. The link-lever structured laser coaxial powder-feeding nozzle with the adjustable powder gathering point allows the powder gathering point to be adjusted dynamically in real time, allows the powder gathering point to fall constantly on the surface of a part under processing, and can provide high-precision high-quality high-performance clad layer with adjustable width of a cladding path.

Description

technical field [0001] The invention relates to a laser coaxial powder feeding nozzle with an adjustable powder converging point of a connecting rod and lever structure. Background technique [0002] With the continuous development of laser cladding technology and the increase of industrial use, the geometry of processed parts is becoming more and more complex. During processing, the width of the cladding track often needs to be changed. During the processing, by directly moving the laser cladding head in the vertical direction, the position of the focus of the laser beam is changed, thereby changing the size of the spot on the surface of the workpiece, and changing the width of the cladding track online. Ordinary laser coaxial powder feeding nozzles cannot adjust the position of the powder converging point online in real time according to the position of the laser beam focus. , Powder aggregation and powder utilization are not high, which undoubtedly limits the populariza...
