[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The ultra-high-speed laser cladding equipment of this embodiment includes a clamping machine tool 1, a driving arm 2 and a laser head 3. A support frame 4 corresponding to the laser head 3 is installed on one side of the driving arm 2, and a collecting box 6 is installed on the support frame 4. A screening unit 7 for screening cladding powder is installed in the collecting box 6.

[0027] like Figure 1-3As shown, the structure of the laser cladding equipment in the utility model is similar to that of the existing laser cladding equipment, such as a laser cladding welding machine tool disclosed in the patent with publication number CN219951213U. The main improvement of the utility model is to collect and reuse the cladding powder dropped by the laser cladding, thereby reducing waste and reducing production costs. When the workpiece needs to be clad, the utility model places the workpiece on the clamping machine 1, and the driving arm 2 moves on the clamping machine 1, and controls the driving arm 2 to drive the laser head 3 to move to the cladding position of the outer wall of the workpiece. The driving arm 2 moves to drive the support frame 4 to move, and the support frame 4 drives the collecting box 6 to follow the movement. At this time, the clamping machine tool 1 drives the clamped workpiece to rotate, and the laser head 3 starts to clad the workpiece, and the driving arm 2 drives the laser head 3 to move slowly. The driving arm 2 always moves the collecting box 6 through the support frame 4, so that the collecting box 6 is always kept directly under the laser head 3, so that the cladding powder dropped from the workpiece will fall into the collecting box 6 for collection, so as to be reused, reduce waste, thereby reducing production costs and improving practicality.

[0028] like Figure 2-5 As shown, the collecting box 6 includes a bottom plate 61, which is mounted on the supporting frame 4. The four corners of the upper surface of the bottom plate 61 are fixedly connected with threaded rods 63. A rectangular frame 64 is sleeved between the plurality of threaded rods 63. The inner wall of the rectangular frame 64 is fixedly connected with an accordion cover 62. The other end of the accordion cover 62 is fixedly connected to the upper surface of the bottom plate 61. The outer wall of the threaded rod 63 is threadedly connected with two nuts 65. The two nuts 65 are respectively located on both sides of the rectangular frame 64. When cladding workpieces of different sizes, the two nuts on the threaded rod 63 can be adjusted. The mother 65 makes the rectangular frame 64 rise or fall, and the rectangular frame 64 is adjusted to be close to the workpiece. At this time, the rectangular frame 64 will drive the accordion cover 62 to expand or contract, so that the accordion cover 62 shields and protects the sides of the bottom plate 61. The accordion cover 62 will block the falling cladding powder, so that the height of the collecting box 6 can be adjusted. When cladding workpieces of different sizes, the upper end of the collecting box 6 can be close to the workpiece, thereby reducing the phenomenon of cladding powder falling outside the collecting box 6, improving the collection rate, reducing waste, and adapting to the use of workpieces of different sizes.

[0029] like Figure 5As shown, the screening unit 7 includes a screening box 71, which is installed just above the bottom plate 61, and both ends of the screening box 71 are fixedly connected with connecting plates 72, and the upper surface of the connecting plate 72 is fixedly connected with a plurality of springs 73, and the other end of the spring 73 is fixedly connected with a mounting bar 74, and the mounting bar 74 is installed with the rectangular frame 64; the cladding powder falling from the workpiece falls into the screening box 71, and the mounting bar 74 supports the connecting plate 72 through the spring 73, and the connecting plate 72 can support the screening box 71, and the screening box 71 can be shaken, and the elastic force of the spring 73 is used to screen out the molten slag in the cladding powder, so that the cladding powder falls onto the bottom plate 61, so as to facilitate the separation of the cladding powder and the slag, so as to facilitate the subsequent reuse of the cladding powder.

[0030] like Figure 5 As shown, the screening unit 7 also includes two brackets 75, and the two brackets 75 are respectively fixedly connected to the two sides of the screen box 71. A cam 76 is rotatably connected inside the bracket 75, and the cam 76 abuts against the workpiece clamped by the clamping machine 1; after the clamping machine 1 clamps the workpiece, the cam 76 abuts against the outer wall of the workpiece. When the clamping machine 1 drives the workpiece to rotate, the workpiece drives the cam 76 to rotate, so that the cam 76 cooperates with the elastic force of the spring 73 to drive the screen box 71 to move up and down, thereby realizing the vibration of the screen box 71, so as to screen the cladding powder entering the screen box 71, realize automatic screening, and improve the convenience of use.

[0031] like Figure 5 As shown, the mounting strip 74 is mounted to the rectangular frame 64 by bolts, and the mounting strip 74 is mounted on the upper surface of the rectangular frame 64; the mounting strip 74 and the rectangular frame 64 are detachable, so that the sieve box 71 can be taken out from the accordion cover 62, so as to facilitate the separation of the cladding powder and slag after screening.

[0032] like Figure 5 As shown, the bottom area of ​​the sieve box 71 is not less than three quarters of the area of ​​the bottom plate 61, and the height of the bottom plate 61 is less than the height of the threaded rod 63; the sieve box 71 has enough area to contact the fallen cladding powder, and the thickness of the sieve box 71 is thin, so that after the accordion cover 62 is contracted, there is space for screening between the sieve box 71 and the bottom plate 61.

[0033] like Figure 3 As shown, a plurality of positioning blocks 5 are fixedly connected to the upper surface of the support frame 4, and the plurality of positioning blocks 5 cooperate with the support frame 4 to limit the bottom plate 61; after the bottom plate 61 is placed on the support frame 4, the plurality of positioning blocks 5 limit multiple directions of the bottom plate 61, so that when the driving arm 2 drives the support frame 4 to move, the bottom plate 61 will not move on the support frame 4, thereby maintaining stability.

[0034] The implementation steps in this embodiment are as follows: when the workpiece needs to be clad, the workpiece is passed through the clamping machine 1, the driving arm 2 moves on the clamping machine 1, and the driving arm 2 is controlled to drive the laser head 3 to move to the cladding position of the outer wall of the workpiece. The movement of the driving arm 2 drives the support frame 4 to move, and the support frame 4 drives the collection box 6 to follow the movement. At this time, the two nuts 65 on the threaded rod 63 are adjusted to make the rectangular frame 64 rise, and the rectangular frame 64 is adjusted to be close to the workpiece. The rectangular frame 64 will drive the accordion cover 62 to expand, so that the accordion cover 62 shields and protects the side of the bottom plate 61, and the cam 76 is against the outer wall of the workpiece. At this time, the clamping machine 1 can drive the clamped workpiece The workpiece rotates, and at the same time, the laser head 3 starts to clad the workpiece, and the driving arm 2 drives the laser head 3 to move slowly. The driving arm 2 always moves the collecting box 6 through the supporting frame 4, so that the collecting box 6 is always kept directly below the laser head 3, so that the cladding powder dropped from the workpiece will fall into the sieve box 71, and the rotation of the workpiece will drive the cam 76 to rotate, so that the cam 76 cooperates with the elastic force of the spring 73 to drive the sieve box 71 to move up and down, so as to realize the vibration of the sieve box 71, so as to screen the cladding powder entering the sieve box 71, separate the cladding powder and slag, and make the cladding powder fall onto the bottom plate 61 for collection for reuse.
