[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a protective cover mechanism for metal polishing according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of a protective cover mechanism for metal polishing provided by this utility model includes a mounting frame 1, which is provided with a protective dust removal component and a filter cleaning component; a polishing machine body 2 is mounted on the top of the mounting frame 1, a polishing disc 3 is mounted on the output end of the polishing machine body 2, and a plurality of electric lifting rods 4 are mounted on the bottom of the mounting frame 1, with workpiece clamps 5 fixedly mounted on the top of the plurality of electric lifting rods 4;

[0027] The protective dust removal assembly includes an upper protective cover 601, a lower protective cover 602, a suction pipe 603, a filter box 604, a filter screen 605, a negative pressure fan 606, and a spring tube 607. The upper protective cover 601 is fixedly installed on the outside of the polishing machine body 2, the lower protective cover 602 is fixedly installed on the outside of the workpiece clamp 5, the suction pipe 603 is fixedly connected to the bottom of one side of the lower protective cover 602, the filter box 604 is fixedly installed at the bottom of the mounting frame 1, the filter screen 605 is inserted into the inside of the filter box 604, the negative pressure fan 606 is fixedly installed on one side of the filter box 604, and the spring tube 607 is fixedly installed on the bottom of the mounting frame 1. Installed between the suction pipe 603 and the filter box 604, the upper protective cover 601 is fitted on the outside of the polishing disc 3, and the outer diameter of the upper protective cover 601 matches the inner diameter of the lower protective cover 602. One end of the suction pipe 603 is connected to the inside of the lower protective cover 602. The suction end of the negative pressure fan 606 is connected to the inside of the filter box 604. One end of the spring tube 607 is connected to one end of the suction pipe 603, and the other end of the spring tube 607 is connected to the inside of the filter box 604. The suction end of the negative pressure fan 606 is located on one side of the filter screen 605, and one end of the spring tube 607 is located at the other end of the filter screen 605.

[0028] The equipment is controlled by an existing mature industrial control system. To achieve synchronous lifting of multiple electric lifting rods 4, a centralized control system can be used. This system includes a controller and signal transmission lines connected to each electric lifting rod 4. After receiving the operation command, the controller sends a synchronous lifting signal to each electric lifting rod 4 through the signal transmission line, thereby ensuring that they can rise or fall simultaneously. In addition, to ensure synchronization, the electric lifting rods 4 should be selected in a consistent manner, with the same lifting speed and load-bearing capacity. The bottom of the filter box 604 has an opening that can be opened and closed for cleaning dust. During polishing, a large-area polishing disc 3 is used for small metal workpieces. During the polishing process, the electric lifting rods 4 are lowered at appropriate times to observe the polishing effect of the metal workpiece, so that the metal workpiece can be flipped or replaced. The height of the lower protective cover 602 can be reasonably designed according to the maximum height of the workpiece to ensure that the workpiece can be covered in most cases.

[0029] It should be noted that by setting up the upper protective cover 601 and the lower protective cover 602, the polishing disc 3 and the workpiece clamp 5 can be covered. A suction pipe 603, a filter box 604, a filter screen 605, a negative pressure fan 606, and a spring tube 607 are also provided for suction and filtration. During use, the electric lifting rod 4 drives the workpiece clamp 5, which holds the metal workpiece to be polished, to rise. The polishing machine body 2 uses the polishing disc 3 to polish the workpiece, which is covered by the upper and lower protective covers 601 and 602. Simultaneously, the negative pressure fan 606 operates, creating negative pressure in the filter box 604. The spring tube 607 and the suction pipe 603 suck up the splashed metal and polishing paste mixed with dust, which is then filtered by the filter screen 605. This allows the dust to be stored on one side of the filter screen 605 inside the filter box 604, preventing any impact on the surrounding environment or the health of personnel.

[0030] Example 2

[0031] In some embodiments, such as Figure 4 As shown, the filter cleaning assembly includes a first cleaning brush 701 and a second cleaning brush 702. The first cleaning brush 701 and the second cleaning brush 702 are fixedly installed inside the filter box 604. The first cleaning brush 701 abuts against one side of the filter screen 605, and the second cleaning brush 702 abuts against the other side of the filter screen 605.

[0032] It should be noted that a first cleaning brush 701 and a second cleaning brush 702 are provided. After a period of use, dust will accumulate on the filter screen 605. At this time, by pushing and pulling the filter screen 605 back and forth, the first cleaning brush 701 and the second cleaning brush 702 can be used to clean both sides of the filter screen 605 and remove the dust attached to the filter screen 605.

[0033] Working principle: During use, the electric lifting rod 4 drives the workpiece clamp 5, which holds the metal workpiece to be polished, to rise. The polishing machine body 2 uses the polishing disc 3 to polish the workpiece. The upper protective cover 601 and the lower protective cover 602 cover the outside. At the same time, the negative pressure fan 606 works, which creates negative pressure in the filter box 604. The spring tube 607 and the suction tube 603 suck up the flying metal and polishing paste mixed with dust, and filter it with the filter screen 605. The dust is stored on one side of the filter screen 605 in the filter box 604 to avoid affecting the surrounding environment and the health of personnel. After a period of use, dust will adhere to the filter screen 605. At this time, push and pull the filter screen 605 back and forth to use the first cleaning brush 701 and the second cleaning brush 702 to clean both sides of the filter screen 605 and remove the dust attached to the filter screen 605. Finally, the bottom of the filter box 604 can be opened to clean the dust collected inside the filter box 604.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
