[0017] The structure of the plasma arc hemming machine provided by the present invention is as Figure 1 and Figure 3 shown, including a frame 1. At the bottom of the frame 1, a plasma generator 11 with adjustable arc frequency is installed. On the surface of the frame 1, an operation button 12 is also installed, and the operation button 12 is electrically connected to the plasma generator 11; a Y-axis linear motor module 3 is fixed on the surface of the frame 1, and a positioning fixture 4 is installed at the top of the Y-axis linear motor module 3. At both ends of the surface of the positioning fixture 4, positioning blocks 41 are installed, and the positioning blocks 41 facilitate the positioning work when the product is placed; on the surface of the frame 1 and outside the Y-axis linear motor module 3, a dual-axis motion mechanism 5 is provided. The dual-axis motion mechanism 5 includes a support frame 51, an X-axis linear module 52, and a Z-axis linear module 53. There are two groups of support frames 51, and the two groups of support frames 51 are fixedly connected to the surface of the frame 1. At the top between the adjacent support frames 51, an X-axis linear module 52 is fixed. The X-axis linear module 52 is electrically connected to the operation button 12. On the sliding seat of the X-axis linear module 52, a Z-axis linear module 53 is installed. The Z-axis linear module 53 is electrically connected to the operation button 12, and the surface of the plasma nozzle 6 is fixedly connected to the sliding seat of the Z-axis linear module 53. A plasma nozzle 6 is provided on the surface of the dual-axis motion mechanism 5, and the plasma nozzle 6 and the plasma generator 11 are connected through a pipeline and cooperate for the hemming work of the product.

[0018] During implementation, one or more de-shelled products are placed on the positioning blocks 41 on the surface of the positioning fixture 4, and are positioned through the positioning blocks 41 when placed. After placement, the operation button 12 is operated to control the Y-axis linear motor module 3 to drive the de-shelled product on the surface of the positioning fixture 4 to move.

[0019] Furthermore, as Figure 2 and Figure 4As shown in the figure, a position sensing mechanism 7 is also provided at the top of the biaxial motion mechanism 5. The position sensing mechanism 7 is used for position sensing during motion. The position sensing mechanism 7 is composed of a sensing piece 71, a support bar 72 and a power-off switch 73. The sensing piece 71 is fixed on the surface of the Z-axis linear module 53 by bolts. The support bar 72 is fixedly connected to the surface of the X-axis linear module 52, and the power-off switch 73 is fixed to the top of the support bar 72 by screws. The power-off switch 73 cooperates with the sensing piece 71 to perform position sensing during the motion of the Z-axis linear module 53; a machine cover 2 is installed at the top of the frame 1, and the machine cover 2 is used for the protection work when pressing the edge of the plasma nozzle 6.

[0020] During implementation, operate the operation button 12 to control the X-axis linear module 52 on the surface of the support frame 51 to move. When the X-axis linear module 52 moves, it will drive the Z-axis linear module 53 to move, so that the Z-axis linear module 53 drives the plasma nozzle 6 to move. During the movement, it is sensed by the position sensing mechanism 7, and then the plasma generator 11 is controlled by the operation button 12 to press and process the original burrs and capes on the surface of the shelled product under the action of the plasma nozzle 6.

[0021] Working principle: When in use, first place one or more shelled products on the positioning blocks 41 on the surface of the positioning fixture 4 according to needs.

[0022] Subsequently, operate the operation button 12 to control the X-axis linear module 52 on the surface of the support frame 51 to move. When the X-axis linear module 52 moves, it will drive the Z-axis linear module 53 to move, so that the Z-axis linear module 53 drives the plasma nozzle 6 to move. During the movement, it is sensed by the position sensing mechanism 7, and then the plasma generator 11 is controlled by the operation button 12 to press and process the original burrs and capes on the surface of the shelled product under the action of the plasma nozzle 6.

[0023] The utility model adopts a set of plasma arc generator and a set of three-axis moving platform for combined use.

[0024] The plasma arc generator of the present utility model forms an ionic arc under the action of an alternating high-frequency high voltage applied across the electrodes with the energy arc of particles in the plasma at low temperatures. The ionic arc is a non-contact jet-type processing technology, which can break the burrs and cloaks on the surface of the plastic shell material without dead angles; through the surface treatment of the product by the low-temperature plasma arc, various physical and chemical changes can occur on the surface of the product material. Processing is carried out under the movement and positioning process of the three-axis platform to suppress the original burrs and cloaks on the surface; at the same time, the high-frequency processing technology of the plasma arc can freely adjust the power of the arc frequency according to the actual processing requirements of the product, so as to achieve the best processing effect of the product.
