[0023] See also Figure 1-Figure 5 As shown, a fine workpiece polishing processing device includes a housing 1, a supporting foot 2 is fixedly connected to the bottom of the housing 1, a card slot 3 is connected to the interior of the housing 1, an insert plate 4 is slidably mounted on the inner side of the card slot 3, and a plurality of air inlet holes 5 are equidistantly opened on the surface of the insert plate 4, a fixing component 6 is fixedly connected to the surface of the housing 1, a mounting ring 7 is fixedly connected to the side of the housing 1, a handheld polisher 8 is mounted on the inner side of the mounting ring 7, an exhaust pipe 9 is fixedly connected to the rear side of the housing 1, and a clamping component 11 is provided through the inner side of the housing 1, and a crank handle 12 is fixedly connected to the surface of one of the clamping components 11;

[0024] Furthermore, the fixing assembly 6 includes a collar 61, a sliding post 62 is slidably connected to the interior of the collar 61, and a pressing block 63 is fixedly connected to one end of the sliding post 62, and the top surface of the pressing block 63 is inclined;

[0025] During operation, due to the inclined top surface of the pressing block 63 , when installing the plugboard 4 , the top of the plugboard 4 presses the inclined surface of the pressing block 63 , causing the pressing block 63 to automatically contract to facilitate the installation of the plugboard 4 .

[0026] Furthermore, a spring 64 is slidably sleeved on the surface of the sliding post 62, and the two ends of the spring 64 respectively press against the inner side of the collar 61 and the inner side of the pressure block 63;

[0027] During operation, the two ends of the spring 64 respectively press against the inner side of the ring 61 and the inner side of the pressure block 63, so that the pressure block 63 has a supporting force away from the side of the ring 61. The pressure block 63 supports the plug board 4, thereby improving the stability of the device during installation.

[0028] Furthermore, the clamping assembly 11 includes a slide rod 111, the inner side of the slide rod 111 is fixedly connected to a connecting piece 112, the inner side of the connecting piece 112 is rotatably connected to a threaded column 113, the surface of the threaded column 113 is threadedly engaged with a clamping plate 114, and the clamping plate 114 is slidably connected to the surface of the connecting piece 112;

[0029] During operation, the connecting member 112 supports and limits the clamping plate 114 through the structural design of the sliding connection between the clamping plate 114 and the surface of the connecting member 112, thereby improving the stability of the device during operation.

[0030] Furthermore, the threads on the surface of the threaded column 113 are symmetrically distributed with the vertical center line of the threaded column 113 as the midpoint;

[0031] During operation, due to the structural design that the threads on the surface of the threaded column 113 are symmetrically distributed on the left and right, when the threaded column 113 rotates, the clamping plate 114 with the threads on the surface of the threaded column 113 slides inward or outward at the same time.

[0032] Furthermore, a filter screen 10 is fixedly embedded at the connection between the housing 1 and the exhaust pipe 9;

[0033] During operation, a filter screen 10 is fixedly embedded in the connection between the housing 1 and the exhaust pipe 9, so that the device can filter and collect dust generated during processing.

[0034] Working principle: During operation, the workpiece to be processed is placed on the inner side of the clamping plate 114, the slide rod 111 is slid to a suitable position, and the threaded column 113 is rotated to make the clamping plate 114 clamp the workpiece inward at the same time. At the same time, the handheld polishing machine 8 is started by an external power supply to polish the workpiece. At the same time, the angle of the clamping assembly 11 is controlled by turning the crank 12 (the surfaces of the clamping assembly 11 on both sides of the housing 1 can be fixedly connected to the crank 12). At the same time, the fan in the exhaust duct 9 is started by an external power supply, and the exhaust duct 9 draws out the air inside the housing 1. The air outside the device carries the dust generated by the polished workpiece into the housing 1 through the air inlet 5, and the dust from the filter 10 is trapped inside the housing 1.

[0035] When the device needs to be cleaned after long-term operation, the pressure block 63 is slid inward and the plug-in board 4 is pulled out from the slot 3 to clean the dust remaining in the shell 1. Due to the design of the inclined surface of the pressure block 63, when the plug-in board 4 is installed, the plug-in board 4 squeezes the pressure block 63 so that the pressure block 63 automatically contracts. When the plug-in board 4 is engaged with the inner side of the slot 3, the pressure block 63 is supported by the spring 64 and automatically pops out to support and limit the plug-in board 4.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
