Sliding blocks 10 are fixedly connected to both the left and right sides of the connecting block 9.

[0033] Refer to Figure 2 - Figure 4, a cylinder 11 is fixedly connected to the bottom side of the displacement mechanism, which is a driving source. The bottom side of the connecting block 9 is fixedly connected to the top side of the cylinder 11, enabling the cylinder 11 to operate stably. The driving end of the cylinder 11 is fixedly connected to a square box 12. By the square box 12 receiving the force in the vertical direction from the cylinder 11, the vertical sliding of the tool can be adjusted. In the middle of the bottom side of the square box 12, a concave frame 13 is fixedly connected. At the right end of the bottom side of the square box 12, a laser melting nozzle 14 is provided for performing welding work.

Due to the restriction of the bottom block 15, the button 16 can slide horizontally. On both the front and rear sides of the button 16, side blocks 17 are fixedly connected to limit the button 16 to prevent it from slipping. A trapezoidal opening 19 is formed inside the side block 17;

[0034] On the adjacent sides of the front and rear ends of the two sliding components, springs 18 are fixedly connected. By fixing the springs 18, the springs 18 can be evenly stressed. A strip-shaped plate 20 is slidably connected to the inner wall of the sliding component. The adjacent sides of every two side blocks 17 are respectively fixedly connected to the opposite sides of every two springs 18. The outer part of the strip-shaped plate 20 is slidably connected to the inner wall of the button 16. The button 16 clamps the strip-shaped plate 20. The bottom sides of the two strip-shaped plates 20 are fixedly connected to a sliding column 21. The outer part of the sliding column 21 is slidably connected to the inner wall of the bottom block 15. Due to the restriction of the bottom block 15, the sliding column 21 can slide vertically and be stably installed. The outer parts of every two side blocks 17 are respectively slidably connected to the inner walls at the left and right ends of the bottom block 15. Due to the restriction of the bottom block 15, the side blocks 17 can slide horizontally. The bottom side of the sliding column 21 is fixedly connected to a tool bit 22. At the rear side of the inner wall of the support platform 1, a water pump 23 is fixedly connected. The input end of the water pump 23 is fixedly connected to a water suction pipe 24. The output end of the water pump 23 is fixedly connected to a transport pipe 25. One side of the transport pipe 25 is fixedly connected to a spray head 26. The pump 23 is connected to the spray head 26 through the water suction pipe 24 and the transport pipe 25 to form an effective cooling and cleaning system. Triangular blocks 27 are fixedly connected to both the left and right sides of the inner wall of the support platform 1.

[0035] Refer to Figure 1 and Figure 5, a protective box 28 is fixedly connected to the rear side of the support table 1 for protecting the driving component. A driving component is fixedly connected to the rear side of the inner wall of the protective box 28. The driving component includes a second motor 29, which is a driving source. The rear side of the second motor 29 is fixedly connected to the rear side of the inner wall of the protective box 28, enabling the second motor 29 to operate stably. A rotating shaft 30 is fixedly connected to the driving end of the second motor 29 for receiving the force of the second motor 29 and transmitting it. Rotating plates 31 are fixedly connected to both the front and rear ends of the driving component. Rubber columns 32 are fixedly connected to the relatively far sides of the rotating plates 31. A blanking plate 33 is fixedly connected to the top end of the inner wall of the support table 1, enabling debris and water to fall. A filter plate 34 is slidably connected to the bottom end of the support table 1 for filtering debris from water. Two force-receiving blocks 35 are fixedly connected to both the relatively close sides of the blanking plate 33 and the filter plate 34. The force is transmitted to the blanking plate 33 and the force-receiving block 35 through the force-receiving force-receiving block 35. The front and rear ends of the rotating shaft 30 are respectively fixedly connected to the inner walls of the two rotating plates 31. One side of the rubber column 32 is in contact with one side of the force-receiving block 35, enabling the rubber column 32 to strike the force-receiving block 35 during the force transmission process. A five-axis turntable 36 is arranged on the top side of the blanking plate 33.

[0036] Working principle: When we need to replace the tool bit 22 that has been used for a long time, at this time, slide by pressing the two buttons 16. Then, when the trapezoidal opening 19 opened inside the button 16 is perpendicular to the strip plate 20, at this time, the strip plate 20 can be disengaged. At the same time, the button 16 will also drive the side block 17 to slide and compress the spring 18, enabling the spring 18 to store elastic potential energy, and then giving the button 16 a force in the opposite direction for reset. When installing, the strip plate 20 abuts against the opening at the bottom side of the button 16. Using the trapezoidal opening 19, an inclined surface is formed on the inner wall of the button 16. Then, the strip plate 20 will push the button 16 to slide. When the triangular notch of the strip plate 20 is parallel to the button 16, the button 16 will slide under the force of the spring 18 for reset, enabling the button 16 to latch the strip plate 20, so as to quickly install the tool bit 22, thereby improving the replacement efficiency.

[0037] When using the device, the part to be processed is placed on the top side of the five-axis turntable 36. At this time, through the electric slide rail 4, the sliding beam 5 can slide left and right, so as to achieve the sliding in the X-axis direction. Then, by driving the electric push rod 8 to push the connecting block 9 to slide, the sliding in the Y-axis direction can be achieved. Then, by driving the cylinder 11 to push the square box 12 to slide downward, the sliding in the Z-axis direction can be achieved, so that the square box 12 has the movement in three axial directions. Then, the square box 12 can drive the tool head 22 to fit with the part. Then, by driving the first driving motor 37, the tool head 22 can rotate and process the part. During the processing, there will be a large amount of debris. At this time, by driving the water pump 23 and using the water suction pipe 24 at the input end to pump out the water inside the bottom end of the support table 1, and then completing the transportation of the water through the transportation pipe 25 at the output end. Then, the water will be sprayed out from the nozzle 26 and wash the debris. Then, the washed debris will fall together from the blanking plate 33 and fall onto the top side of the filter plate 34. At this time, by driving the second driving motor 29 to drive the rotating shaft 30 to rotate, the two rotating plates 31 are driven to rotate, and then each rotating plate 31 will drive the two rubber columns 32 to rotate and strike the force-receiving block 35 on the side close to the blanking plate 33 and the filter plate 34, so that the debris on the top sides of the blanking plate 33 and the filter plate 34 can fall and be filtered. The filtered water will return to the inside of the support table 1 and be used again, thus avoiding the waste of water resources.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
