[0002] Machining refers to the process of using various mechanical equipment and tools to process metal and non-metal materials through cutting, grinding, polishing and other means to obtain the desired shape, size and surface quality. Machining is the foundation of the manufacturing industry and is widely used in aviation, aerospace, automobiles, ships, precision instruments and other fields.

[0003] During the grinding process, due to the high friction between the abrasive and the workpiece surface, a large amount of chips and metal powder will be generated. These tiny particles are suspended in the air. If the operator does not take appropriate protective measures during the grinding process, such as wearing a dust mask, etc., it is possible to inhale these fine metal powders into the respiratory system. Long-term inhalation of these particles may have adverse effects on physical health, such as causing lung disease, respiratory irritation or other health problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a portable grinding device for mechanical processing, comprising a bottom plate 1, a roller 2 is connected under the bottom plate 1, a workbench 3 is connected on the bottom plate 1, a moving assembly 4 is connected on the workbench 3, a grinding assembly 5 is connected to the front of the moving assembly 4, a shielding device 6 is provided on the outer cover of the grinding assembly 5, a dust collecting device 7 is connected inside the shielding device 6, the dust collecting device 7 comprises a connecting plate 71, the connecting plate 71 is connected to one side of the moving assembly 4, a collecting box 72 is connected to one side of the connecting plate 71, a rotating plate 73 is rotatably connected to one side of the collecting box 72, a limiting rod 74 is connected to one side of the rotating plate 73, a long slot 75 is provided in the rotating plate 73, a filter screen 76 is slidably connected in the collecting box 72, by providing the long slot 75 and the filter screen 76, the long slot 75 cooperates with the filter screen 76, so that when replacing the filter screen 76, it is realized that the filter screen 76 can be replaced or cleaned by simply pulling it out of the long slot 75;

[0021] A dust suction fan 77 is connected through the back of the collection box 72, and a pipe 78 is connected through the front of the collection box 72. A connecting pipe 79 is provided on the outer sleeve of the pipe 78, and the connecting pipe 79 is connected through the transparent shell 61. The shielding device 6 includes a transparent shell 61, which is sleeved and slidably connected to the outside of the grinding assembly 5, and a fixed plate 64 is connected to the outside of the grinding assembly 5. Two sliding rods 62 are connected to the transparent shell 61, and a limiting plate 63 is connected to the sliding rod 62. The fixed plate 64 is slidably connected to the outside of the sliding rod 62. By setting the sliding rod 62 and the fixed plate 64, the sliding rod 62 cooperates with the fixed plate 64, so that the fixed plate 64 limits the sliding rod 62 to prevent the sliding rod 62 from shaking when sliding;

[0022] The slide bar 62 is provided with a pull-back spring 65. By providing the pull-back spring 65, during the processing, the pull-back spring 65 applies elastic force to the transparent shell 61 to keep it in contact with the workbench 3. When the transparent shell 61 gradually moves away from the workbench 3, the pull-back spring 65 applies elastic force to the transparent shell 61, and the elastic force drives the transparent shell 61 to move, so that it can be quickly reset.

[0023] One end of the return spring 65 is connected to the transparent shell 61 , and the other end of the return spring 65 is connected under the fixing plate 64 .

[0024] The working principle of the utility model is:

[0025] When processing is required, the moving component 4 drives the grinding component 5 to move, and the grinding component 5 drives the transparent shell 61 to move, and then the transparent shell 61 fits with the workbench 3. If it continues to move, the transparent shell 61 applies a thrust to the slide bar 62, and the thrust drives the slide bar 62 to slide in the fixed plate 64. During the processing, the dust suction fan 77 is started, and the dust suction fan 77 generates suction in the collection box 72. The suction passes through the pipe 78 and then is transmitted from the connecting pipe 79. At this time, the connecting pipe 79 absorbs the debris and metal powder in the transparent shell 61. When the debris and metal powder pass through the pipe 78, they are sucked into the collection box 72 and then blocked by the filter 76. When the filter 76 needs to be replaced, it is only necessary to pull the filter 76 out of the long groove 75 for replacement. When the collection box 72 needs to be cleaned, it is only necessary to remove the limit rod 74 and pull the rotating plate 73 to clean the collection box 72. At this point, the blocking, cleaning and collection of the debris and metal powder are completed.
