Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, and more specifically to a polishing machine for numerical control machining of a television back panel accessory with a dustproof effect. Background Art

[0002] Polishing machines are also called grinders, and are often used for mechanical grinding, polishing and waxing. The working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the combined effect of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed. The speed of the polishing disc is generally 1500-3000r / min, and most of them are stepless. It can be adjusted at any time according to needs during construction. Polishing is required when processing TV back panel accessories.

[0003] For example, the patent with application number CN202023288948.1 discloses a polishing device for CNC machining of TV back panel accessories, including a supporting base and a supporting frame, a supporting frame is installed on the upper end of the supporting base, a power control box is arranged on the right side of the supporting frame, a polishing machine body is arranged on the rear side of the supporting frame, a spindle lifting device is arranged on the left side of the polishing machine body, a rotating spindle is arranged on the front side of the polishing machine body, a grinding wheel is sleeved on the outside of the rotating spindle, and the height of the supporting slide groove at the lower end of the placing platform A and the placing platform B on the supporting base is adjusted so that the height of the placing platform C is higher than the placing platform A and the placing platform B, and the convex surface of the object is placed on the upper end of the placing platform C, and the bottom end of the product can contact the placing platform A and the placing platform B. After completing the polishing of the convex surface, the grinding wheel is moved on the rotating spindle to polish both sides of the product respectively, thereby avoiding damage to the product.

[0004] The device is detachable so that multiple sets of placement platforms can effectively support the hollow TV back panel accessories, but the placement platforms need to be manually disassembled and assembled under different usage requirements, which is inconvenient. At the same time, debris and smoke will be generated during polishing. If not handled in time, the smoke will spread and affect the environment and human body. Therefore, professionals in this field provide a polishing machine for CNC processing of TV back panel accessories with dustproof effect. Utility Model Content

A collecting box 12 is fixedly connected to the synchronous seat 6, and the inside of the collecting box 12 is fixedly connected to connecting pipes 13 arranged at equal distances, and the other end of the connecting pipe 13 is located inside the annular box 10. An air pump 14 connected to the inside of the collecting box 12 is fixedly installed, and a filter plate 15 is detachably connected to the inner wall of the collecting box 12. A supporting assembly 16 is provided on the top of the machine base 1, and the cross-sectional shape of the through groove 11 is narrow at the top and wide at the bottom;

[0024] The support assembly 16 includes an electromagnetic seat 1601 and an electromagnetic seat 2 1602, which are fixedly mounted on the inner bottom wall of the base 1. The top of the base 1 is slidably connected with an annular plate 1603 and an annular plate 2 1604, and the annular plate 2 1604 is located on the inner side of the annular plate 1 1603. The bottoms of the annular plates 1603 and 1604 are fixedly connected with evenly distributed guide columns 1605. The interior of the base 1 There are sliding connections with magnetic plate 1 1606 and magnetic plate 2 1607, which are respectively located at the top of electromagnetic seat 1 1601 and electromagnetic seat 2 1602 and are magnetically connected to electromagnetic seat 1 1601 and electromagnetic seat 2 1602, respectively, and the tops of magnetic plate 1 1606 and magnetic plate 2 1607 are fixedly connected to the bottom of guide column 1605, and electromagnetic seat 1 1601 and electromagnetic seat 2 1602 are both electrically connected to control panel 17.

[0025] When the back plate accessory needs to be polished, the user can place the accessory on the top of the support seat 2 so that the two sides of the back plate accessory are on the top of the annular plate 1 1603 and the annular plate 2 1604, and then the user controls the push rod 7 and the drive motor 8 to energize and work.

[0026] In the utility model, the polishing wheel 9 is arranged inside the synchronous seat 6 and the annular box 10 is arranged to surround the polishing wheel 9. When the debris and smoke generated during polishing are diffused, they are sucked into the collection box 12, thereby preventing the diffusion of debris and smoke and achieving a dust-proof effect. At the same time, the support component 16 can provide good support for back panel accessories of different specifications. The height of the annular plate 1 1603 and the annular plate 2 1604 can be changed without manual disassembly and assembly, thereby preventing the internal hollow back panel accessories from being deformed due to pressure.
