The first docking component 3 includes a concave frame 301, which is fixed to the upper end of the fixed support block 2. The concave frame 301 has a locking hole 302 at both ends of its surface, and a pressing block 303 is provided on the locking hole 302. The left and right ends of the two sets of pressing blocks 303 are connected by springs 304. A limiting block 305 is provided below the two sets of pressing blocks 303 and located inside the concave frame 301. The part is rotatably connected to an adjusting screw 306 threadedly connected to the concave frame 301. The upper part of the limiting block 305 is set in the shape of an isosceles trapezoid, and the limiting block 305 is located between two sets of springs 304 on the extrusion block 303. The limiting block 305 is slidably connected to the concave frame 301. It can move upward through the limiting block 305 to extrude the two sets of extrusion blocks 303, so that the two sets of extrusion blocks 303 can move outward, which is convenient for extruding and fixing the slide rail installed on the docking assembly. The upper part of the fixed support block 2 is fixed with a servo motor 7, and the output end of the servo motor 7 is fixed with a rotating screw 8. The rotating screw 8 is threadedly connected to the movable support block 5, and the lower part of the movable support block 5 is engaged with the slide groove 4 on the surface of the base plate 1. It can move threadedly through the rotating screw 8 and the movable support block 5, so that the movable support block 5 can slide on the slide groove 4 on the surface of the base plate 1, which is convenient for docking the slide rail.

[0024] Please see Figure 1-5Support plates 9 are fixed to the left and right sides at both ends of the base plate 1. A splash-proof assembly 10 is installed above the support plates 9. The splash-proof assembly 10 includes a movable plate 1001. A first positioning bolt 1002 is connected to the lower inner surface of the movable plate 1001. Side plates 1003 are fixed to both the front and rear sides of the movable plate 1001. Locking blocks 1004 are fixed to the upper and lower ends of the outer surface of the movable plate 1001. A limit plate 1005 is installed inside the locking blocks 1004. A second positioning bolt 1006 is connected to the locking blocks 1004 below the surface of the movable plate 1001. The movable plate 1001 is U-shaped. The movable plate 1001 and... The support plate 9 forms a telescopic connection, and the surface of the movable plate 1001 is fixedly connected to the support plate 9 by the first positioning bolt 1002, which facilitates the use of the movable plate 1001 in conjunction with the first positioning bolt 1002, so that the movable plate 1001 can protect the top of the slide rail. The locking block 1004 is set in an "L" shape, and the limiting plate 1005 is slidably connected to the locking block 1004 on the surface of the movable plate 1001. The surface of the locking block 1004 is fixedly connected to the limiting plate 1005 by the second positioning bolt 1006, which can facilitate the protection of the side of the slide rail by using the limiting plate 1005 in conjunction with the second positioning bolt 1006.

[0025] Working principle: First, during use, the slide rail is engaged on the first docking assembly 3. By rotating the adjusting screw 306 below the concave frame 301, the adjusting screw 306 moves threadedly with the concave frame 301, causing the adjusting screw 306 to drive the limiting block 305 to slide inside the concave frame 301. The limiting block 305, which is isosceles trapezoidal in shape at its upper end, slides inside the concave frame 301. When the limiting block 305 slides, it presses against the pressing block 303 on the surface of the card hole 302 on the surface of the concave frame 301, thereby compressing... Block 303 moves outward to facilitate the positioning of the slide rail compression support. The two sets of compression blocks 303 on the concave frame 301 are connected by spring 304 to facilitate the reset of the compression block 303 and improve the performance of the device. Similarly, the other slide rail is installed on the second docking assembly 6. During docking, the servo motor 7 can be turned on so that the servo motor 7 drives the movable support block 5 to move threadedly by rotating the lead screw 8, so that the movable support block 5 can slide on the slide groove 4 on the surface of the base plate 1, which facilitates the docking work between the two sets of slide rails.

[0026] After the two sets of slide rails are installed, the movable plate 1001 on the splash guard assembly 10 can be slid to slide on the support plate 9 in a U-shape, so that the lower middle part of the movable plate 1001 is in contact with the upper part of the slide rail. By rotating the first positioning bolt 1002 under the movable plate 1001, and then by sliding the limiting plate 1005 on the side block 1004 of the movable plate 1001, the inner end of the limiting plate 1005 is in contact with the surface of the slide rail. The limiting plate 1005 is then positioned by the second positioning bolt 1006 to protect one side of the slide rail. Similarly, the movable plate 1001 and side plate 1003 on the other side are installed so that the splash guard assembly 10 forms a frame-shaped cover, which facilitates protection during the laser welding process and avoids the problem of welding slag splashing. This is the working principle of the laser welding feeding slide rail docking fine adjustment fixture.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
