Hinge and sliding block type laser coaxial powder feeding nozzle with adjustable powder focal point

Abstract

Provided is a hinge and sliding block type laser coaxial powder feeding nozzle with the adjustable powder focal point. Powder feeding pipes are arranged outside a cladding head and located on the periphery of the cladding head through angle adjusting devices. Each angle adjusting device comprises a sleeve, wherein a driving device is arranged on one side of the sleeve. Each powder feeding pipe is located outside the corresponding sleeve, and a sliding rail part is arranged at the end, close to an inlet of each powder feeding pipe. A sliding block part is fixed to each sleeve and slidably arranged on the corresponding sliding rail part, and each sliding block part is connected with the corresponding sliding rail part through a buckle device to prevent the sliding block part from being separated from the sliding rail part in the sliding process. The end, close to an outlet, of each powder feeding pipe is hinged to the cladding head. A central controller is connected with the driving devices. The hinge and sliding block type laser coaxial powder feeding nozzle can dynamically adjust the powder gathering point in real time while the laser defocusing amount is changed, the powder gathering point is made to be located on the surface of a machined part all the time, a clad layer high in precision and quality and good in performance is obtained, and the cladding track width can be changed.

Description

technical field [0001] The invention relates to a hinge slider type laser coaxial powder feeding nozzle with adjustable powder focus. 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 popularization and application of laser claddi...
