The fixing assembly 5 includes a mounting frame 501, the bottom of the mounting frame 501 is fixedly connected to the top of the fixing frame 1, the inner surface of the mounting frame 501 is rotatably connected to a second threaded rod 506, the outer surface of the second threaded rod 506 is threadedly rotatably connected to a moving plate 503, the outer surface of one side of the moving plate 503 is fixedly connected to a second motor 505, and the output end of the second motor 505 rotates through the outer surface of one side of the moving plate 503 The output end of the second motor 505 is fixedly connected to the second clamping block 504, one end of the second threaded rod 506 rotates to penetrate the outer surface of the mounting frame 501 and extends outward, one end of the second threaded rod 506 is fixedly connected to the hand wheel 507, the inner surface of the mounting frame 501 is rotatably connected to the first clamping block 502 at a position away from the second clamping block 504, the movable plate 503 is slidably connected to the mounting frame 501, and a plurality of nozzles 408 are evenly arranged on the inner side of the diverter block 407, and the nozzles 408 are connected to the diverter block 407.

[0023] The effect achieved by the entire embodiment 1 is that when the laser cladding cooling device is used, first, one end of the workpiece is pressed against the inner side of the first clamping block 502, and the other end of the workpiece is aligned with the second clamping block 504, and the hand wheel 507 is turned to drive the second threaded rod 506 to move in a clockwise direction, and the movable plate 503 will slide along the inner side of the mounting frame 501, driving the second clamping block 504 to press against the other end of the workpiece, playing a fixing role. During the laser cladding process, the laser cladding device 6 starts the laser irradiation operation after adjusting the position according to the position of the workpiece to be processed. After the workpiece is processed, the laser cladding device 6 is lifted upward by its lifting mechanism to avoid, and the electric telescopic rod 403 is started, and its telescopic end first extends outward to drive the fixed block 404 to move forward, so that the bearing rod 405 drives the diverter block 407 to move forward synchronously, and is pulled away from the mounting frame 501 by a certain distance to avoid collision with the mounting frame 501 during subsequent operations, and the first motor 2 is started. When the output end of the first motor 2 rotates clockwise and drives the first threaded rod 3 to rotate, the moving block 401 will move along its surface toward the first motor 2.

[0025] The effect achieved by the entire embodiment 2 is that, when in use, a bottom plate 7 is fixedly set on the inner surface of the fixed frame 1, and a slide groove 8 is opened on the surface of the fixed frame, so that when the movable block 401 moves due to the rotation of the first threaded rod 3, the movable block 401 will slide in the slide groove 8 through the slider 402, which plays a role of limiting. At the same time, the contact area between the movable block 401 and the bottom plate 7 is reduced, so that the movable block 401 is smoother when sliding in a limited position, thereby improving the stability of the laser cladding cooling device.

[0026] Working principle: when the laser cladding processing of the workpiece is completed, the electric telescopic rod 403 is started, and its telescopic end first extends outward, driving the fixed block 404 to move forward, so that the bearing rod 405 drives the diverter block 407 to move forward synchronously, and is pulled away from the mounting frame 501 by a certain distance to avoid collision with the mounting frame 501 during subsequent operations. The first motor 2 is started, and the output end of the first motor 2 rotates clockwise. When driving the first threaded rod 3 to rotate, the moving block 401 will slide in the slide groove 8 through the slider 402, which plays a role of limiting. At the same time, the contact area between the moving block 401 and the bottom plate 7 is reduced, so that the moving block 401 is smoother when sliding in the limited position. The moving block 401 will move along its surface toward the first motor 2. When it moves to the cladding point on the surface of the workpiece, the driving of the first motor 2 is stopped. Motor 2, at this time, the telescopic end of the electric telescopic rod 403 is reset, driving the fixed block 404 to move backward, so that the arc-shaped diverter block 407 will be relatively close to the surface of the workpiece, and the external conveying device is connected with the pipe body 406 to convey the cooling medium to the diverter block 407. Multiple atomizing nozzles 408 will evenly atomize the cooling medium into fine particles, and evenly spray the surface of the workpiece to achieve a cooling effect. The cooling medium can be a gas cooling material such as water or liquid nitrogen. At the same time, the second motor 505 can be started at the same time. When the output end of the second motor 505 drives the second clamping block 504 to rotate, the clamped and fixed workpiece will drive the first clamping block 502 to rotate synchronously, so that the surface of the workpiece will be evenly sprayed with the cooling medium, further improving the cooling effect of the workpiece.
