[0030] Working principle: The screw rod surface alloy processing equipment is mainly used for processing a layer of high-performance alloy material on the surface of a screw rod (such as an extruder screw rod, an injection molding machine screw rod, etc.), so as to improve the wear resistance, corrosion resistance, high temperature resistance and service life of the screw rod. The processing principle is usually based on surface engineering technology, and the alloy material is combined with the screw rod base body through a specific process to form a composite reinforcement layer. A high-energy density laser beam (such as a fiber laser, a CO2 laser) is used to irradiate the surface of the screw rod, and the alloy powder (such as nickel-based, cobalt-based, ceramic composite powder) is synchronously conveyed. After the powder and the base surface layer are quickly solidified, a pore-free and dense alloy layer is formed; Therefore, when the screw is surface alloyed, according to the requirement of the different length of the screw to be processed, first, the screw is placed in the four clamping jaws 38, then the cylinder 2 37 is controlled by the control device, at this time, the cylinder 2 37 extends outward, thereby pushing the slider 37 connected with the output end of the cylinder 2 37 to move, further pushing the L-shaped rod 2 34 to deflect, and synchronously pushing the other three L-shaped rods 34 to deflect by the rectangular plate 33, thereby driving the other three sliders 37 to move synchronously and close to the middle screw, and the clamping jaws 38 are brought close to each other by the synchronous closing sliders 37, and the outer wall of the screw is clamped to fix the screw, then the motor 1 32 is controlled to rotate, thereby driving the rotating disc 31 to rotate, and further driving the screw to rotate; Further, according to the length of the screw, the cylinder 1 25 is controlled, the cylinder 1 25 extends outward, and the adjusting table 22 is pushed to move, thereby moving the synchronous supporting mechanism 4 to the outer wall of the screw to assist in supporting the screw, when moving to the screw, the motor 2 49 is started, at this time, the motor 2 49 drives the adjusting screw 47 to rotate, thereby threadedly pushing the push block 46 to move, thereby rotating the rotating ring 41 on the adjusting table 22, thereby rotating the sliding sleeve 43 and deflecting the sliding rod 42 by the deflection of the rotating ring 41, thereby extruding the sliding rod 42 to the screw, and pushing the rubber wheel 45 against the surface of the screw, thereby realizing the auxiliary support of the screw, at the same time, when the screw rotates, the rubber wheel 45 clamps the screw and rotates synchronously to realize the processing of the screw thread groove on the outer wall of the screw; Further, according to the different diameters of the screw, the cylinder 3 72 is driven, at this time, the laser generator 73 is pushed to the screw to adjust the spraying distance to adapt to the processing of screws with different diameters, at the same time, the brush plate 712 is synchronously pushed to the outer wall of the screw, at this time, the screw is pushed, when the screw rotates, it moves relative to the brush plate 712, thereby brushing the outer wall of the screw on the left side of the screw to remove the dust attached to the surface of the screw, thereby improving the adhesion rate of the alloy powder, and brushing the outer wall of the screw on the right side of the screw to clean the area cooled after cladding to remove the unattached metal powder, thereby achieving the purpose of self-cleaning; Further, the motor 3 is started, at this time, the half gear 76 is driven to rotate, thereby driving the movable table 71 to move by engaging the tooth groove 77, when the half gear 76 rotates to disengage from the tooth groove 77, at this time, the movable table 71 is reset under the action of the spring 2 74, thereby realizing the continuous movement of the movable table 71, when the movable table 71 continuously moves, the cylinder 3 72 is driven to move, and the axial position of the laser generator 73 relative to the screw is changed, thereby improving the processing range and the cladding effect, Further, the sliding table 52 is directly driven to slide on the slide rail 53 by an external driving device, and the moving speed is controlled to cooperate with the rotating speed of the screw to realize the processing of the metal powder on the outer wall of the screw by the moving laser generator 73. When the sliding table 52 moves, the elastic push rod 57 is synchronously driven to move, so that the dislocation movement is generated after the contact with the rack 54, the elastic push rod 57 is reversely moved, the L-shaped rod one 56 and the U-shaped inner rod 55 are synchronously driven to move, and the U-shaped inner rod 55 is reset under the action of the spring one 59 after the disengagement from the rack. At the same time, when the U-shaped inner rod 55 moves, the L-shaped fixed rod 711 is pushed to move, the movable block 79 is pushed to move on the connecting plate 78, and the brush plate 712 is axially moved relative to the screw, so that the brushing effect is further improved.
