Since the switcher changes the inclination state of the workbench through the inclination component, and the switcher changes the position states of the transfer table and the workbench through the synchronization component and the second driving gear.

[0036] Since the switch changes the rotation state of the driving gear II 5 and the workbench 2 through the switching component 7, when direct current is applied to the electro-suction cup 72 and the electro-suction ball 71, the electro-suction ball 71 and the electro-suction cup 72 will generate the same magnetic field and drive the electro-suction ball 71 and the electro-suction cup 72 away from each other. At this time, driving the driving gear II 5 to rotate by the servo motor 6 will only cause the driving gear II 5 to move relative to the rack 31, while the workbench 2 will remain stationary and the cladding operation can be carried out normally; conversely, by applying direct current to the electro-suction ball 71 and the electro-suction cup 72 to generate the same magnetic field between the electro-suction ball 71 and the electro-suction cup 72, the electro-suction ball 71 and the electro-suction cup 72 can be attracted to each other to achieve the fixed connection effect between the workbench 2 and the driving gear II 5. At this time, rotating the driving gear II 5 will also drive the workbench 2 to rotate, so as to achieve the effect of material rotation.

[0043] As a further solution of the present invention: an automatic feeding device for laser cladding additive manufacturing, a first driving gear 44 and a driven gear 45 are rotatably connected to one side of the transfer table 4. One end of the driven gear 45 extends into the transfer table 4 and is fixedly connected to a rotating magnet 46. The first driving gear 44 is meshed with the driven gear 45.

[0044] Since a first driving gear 44 and a driven gear 45 are rotatably connected to one side of the transfer table 4, one end of the driven gear 45 extends into the transfer table 4 and is fixedly connected to a rotating magnet 46, and the first driving gear 44 is meshed with the driven gear 45, the driven gear 45 can be driven to rotate by the rotation of the first driving gear 44. After the driven gear 45 rotates, the magnetic pole of the rotating magnet 46 can be rotated, so that the magnetic pole of the rotating magnet 46 is in direct contact with the transfer table 4, and the magnetic attraction of the object on the transfer table 4 can be realized, avoiding the problem of material dropping on the transfer table 4.

At this time, driving the second driving gear 5 to rotate by the servo motor 6 will only cause the second driving gear 5 to move relative to the rack 31, while the workbench 2 will remain stationary and the cladding operation can be carried out normally. On the contrary, when direct current is applied to the electro-suction ball 71 and the electro-suction cover 72 to generate the same magnetic field, the electro-suction ball 71 and the electro-suction cover 72 can be attracted to each other, achieving the effect of fixed connection between the workbench 2 and the second driving gear 5. At this time, the rotation of the second driving gear 5 will also drive the rotation of the workbench 2, thus realizing the effect of material rotation. The switching process is simple and the switching efficiency is high.

[0050] Since the switcher changes the inclination state of the workbench 2 through the inclination component 8, and the switcher switches the position states of the transfer table 4 and the workbench 2 through the synchronization component 3 and the second driving gear 5. Specifically, the inclination operation of the switching component 7 is realized by the mutual attraction or repulsion of two groups of electro-suction sheets 83, which is convenient for the cladding operation at the corners of the material to be clad.

[0051] Since one side of the transfer table 4 is rotatably connected with a first driving gear 44 and a driven gear 45, one end of the driven gear 45 extends into the transfer table 4 and is fixedly connected with a rotating magnet 46, and the first driving gear 44 is meshed with the driven gear 45. Therefore, the rotation of the first driving gear 44 can drive the meshed driven gear 45 to rotate. After the driven gear 45 rotates, the magnetic poles of the rotating magnet 46 can be rotated, so that the magnetic poles of the rotating magnet 46 are in direct contact with the transfer table 4, realizing the magnetic attraction of the objects on the transfer table 4 and avoiding the problem of material dropping on the transfer table 4.
