▎ 摘　　要

NOVELTY - The device has a prefabricated sample preparation component (1) and an ultrasonic-assisted laser micro-cladding component that are installed on a rack. A T-shaped platen assembly (104) includes a T-shaped platen, and is fixedly installed on the layer board (105) in four rows and six columns. A laser rangefinder (106) is fixed on a vertical sliding plate (108) through a rangefinder mounting plate (107). A linear bearing (109) is installed coaxially with a guide rod (110). A total of four groups of linear bearings are distributed at the four top corners of the vertical sliding plate. The upper and lower ends of the guide rod are fixed on a bottom plate (101) and a linear motor mounting plate (112). The two sets of connecting bolts (111) which are symmetrically arranged on both sides of the vertical sliding plate are provided. A metal partition plate is in the shape of a nine-square grid, and partitions an auxiliary temperature control heating module. USE - Gradient functional composite material ultrasonic-assisted laser micro-cladding device used in additive manufacturing and industrial manufacturing. ADVANTAGE - The device forms high quality gradient function composite coating in metallurgical bonding way through laser micro-cladding technology. The auxiliary temperature control heating module improves the absorption rate of the pre-set sample to the laser in the microcladding process, the bonding rate with the base material is improved, and the effect is kept layer by layer, and has heat preservation effect, prevents the cladding layer quickly cooling to cause surface crack, introduces ultrasonic vibration auxiliary energy field, under the acoustic flow effect and cavitation effect comprehensive effect, in the multilayer multi-channel micro-cladding process. The whole fluidity of the molten pool is changed, changes the gas-liquid interface of molten tank, promotes gas fast overflow, reduces internal stress caused by temperature gradient difference, and inhibits generation of micro-crack and air hole defect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a laser micro-cladding method based on the gradient functional composite material ultrasonic-assisted laser micro-cladding device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of prefabricated sample preparation assembly of gradient functional composite material ultrasonic-assisted laser micro-cladding device. 1Prefabricated sample preparation component 101Bottom plate 102First ultrasonic vibrator assembly 103Mold grid plate 104T-shaped platen assembly 105Layer board 106Laser rangefinder 107Rangefinder mounting plate 108Vertical sliding plate 109Linear bearing 110Guide rod 111Connecting bolt 112Linear motor mounting plate 113Linear motor
