[0025] Example 2

[0026] Reference Figure 1-5 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0027] The clamping assembly includes a mounting frame 8, a motor 9 and a three-jaw self-centering chuck 10. The mounting frame 8 is fixed at one end inside the processing box 1, and the motor 9 is installed on the inner side of the mounting frame 8. The three-jaw self-centering chuck 10 is rotatably installed on the outer side of the mounting frame 8 and connected to the output end of the motor 9. The arrangement of the clamping assembly facilitates the clamping of cylindrical workpieces and can conveniently drive the workpiece to rotate during the additive processing process, so that the laser additive processing robot arm can better process the tool; a threaded barrel 11 is fixed at one end of the processing box 1 away from the motor 9, a threaded rod 12 is installed inside the threaded barrel 11, one end of the threaded rod 12 extends to the outside of the threaded barrel 11 and is rotatably installed with a clamping disk 13, and the arrangement of the threaded barrel 11, the threaded rod 12 and the clamping disk 13 makes When a person rotates the threaded rod 12, the clamping plate 13 can be driven to move until the clamping plate 13 is clamped on the end of the workpiece away from the three-jaw self-centering chuck 10, that is, at this time, both ends of the workpiece can be clamped and fixed more fully, so that the workpiece can be kept stable more easily during processing; a rotating frame 14 is fixed on the rod body of the threaded rod 12 located between the threaded tube 11 and the clamping plate 13, and a plurality of locking bolts 15 are threadedly installed on the threaded tube 11 at the end of the rotating frame 14 away from the clamping plate 13. The setting of the rotating frame 14 makes it convenient for a person to drive the threaded rod 12 to rotate, and the setting of the locking bolts 15 makes it convenient to maintain a fixed connection between the threaded rod 12 and the threaded tube 11, which is convenient for avoiding the threaded rod 12 from loosening due to vibration during use.

[0028] A guide plate 16 is fixed on the top surface of the processing box 1, and the lower surface of the guide plate 16 is in an inclined state and the high end is close to one end of the air inlet and outlet pipe 2. The setting of the guide plate 16 allows the air to be fully discharged to the outside of the processing box 1 along the guide plate 16 when the air is discharged from the processing box 1; oxygen sensors 17 are provided on the tube bodies of the air inlet and outlet pipes 2 and the protective gas inlet pipe 5, and observation windows 18 are provided on both sides of the processing box 1. The setting of the observation windows 18 facilitates personnel to observe the processing conditions of the workpieces inside the processing box 1; a pressure gauge 19 for detecting gas pressure is installed at one end of the processing box 1, and a matching filter screen 20 is installed inside the collecting box 3 corresponding to the protective gas outlet pipe 4 and the protective gas inlet pipe 5. The setting of the pressure gauge 19 facilitates monitoring the internal pressure of the processing box 1, and the setting of the filter screen 20 facilitates preventing debris generated during processing from entering the protective gas outlet pipe 4 and the protective gas inlet pipe 5.

[0029] Principle and advantages of use: During the use of the utility model, the personnel install the mechanical arm for laser additive processing inside the processing box 1, and then when performing laser additive processing, first close the control valve on the protective gas inlet pipe 5, and open the control valves on the air inlet and outlet pipes 2 and the protective gas outlet pipe 4. At this time, the carbon dioxide protective gas provided by the external gas source enters the processing box 1 through the protective gas outlet pipe 4. Since the density of carbon dioxide gas is greater than that of air, the protective gas settles on the bottom surface of the processing box 1, and as the protective gas continues to flow in, the protective gas continues to accumulate at the bottom of the processing box 1 and pushes the air inside the processing box 1 to move upward until the processing box 1 is pushed by the protective gas to be discharged through the air inlet and outlet pipe 2. When the air inside the processing box 1 is discharged, the control valve at the air inlet and outlet pipe 2 is closed to avoid leakage of the protective gas inside the processing box 1, thereby allowing the protective gas to provide anti-oxidation protection for the workpiece inside the processing box 1; and when the workpiece needs to be taken out after the material addition is completed, the control valve on the protective gas outlet pipe 4 is closed, and the air inlet and outlet pipe 2 and the control valve at the protective gas inlet pipe 5 are opened. That is, at this time, the protective gas inside the processing box 1 is sucked in by the pump 6 and transported to the gas storage tank 7 for storage, thereby realizing the effect of recycling the protective gas inside the processing box 1 so that it can be reused after recycling.

[0030] It should be further explained that the setting of the clamping assembly facilitates the rotation of the workpiece, so that the laser additive processing robot arm can better process the tool, and when the workpiece is irregular, it can be directly placed on the bottom surface of the collection box 3 for processing; the setting of the threaded barrel 11, the threaded rod 12 and the clamping plate 13 allows personnel to drive the clamping plate 13 to move by rotating the threaded rod 12 until the clamping plate 13 is clamped at the end of the workpiece away from the three-jaw self-centering chuck 10, that is, at this time, both ends of the workpiece can be clamped and fixed more fully, so that the workpiece is easier to keep stable during processing; the setting of the rotating frame 14 facilitates personnel to drive the threaded rod 12 to rotate, and the setting of the locking bolt 15 facilitates the threaded rod 12 and the threaded barrel. 11 maintains a fixed connection, so as to prevent the threaded rod 12 from loosening due to vibration during use; the setting of the guide plate 16 allows the air to be fully discharged to the outside of the processing box 1 along the guide plate 16 when the air is exhausted from the processing box 1; the setting of the observation window 18 is convenient for personnel to observe the processing status of the workpiece inside the processing box 1, and the setting of the oxygen sensor 17 is convenient for monitoring the oxygen concentration in the exhaust gas inside the processing box 1, so as to facilitate the corresponding on-off control of the air inlet and outlet pipes 2 and the protective gas inlet pipe 5 and the protective gas outlet pipe 4; the setting of the pressure gauge 19 is convenient for monitoring the internal pressure of the processing box 1, and the setting of the filter screen 20 is convenient for preventing the debris generated during processing from entering the protective gas outlet pipe 4 and the protective gas inlet pipe 5.
