[0034] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-7The present invention shows an environment-friendly polishing and grinding equipment for sheet metal processing, which includes a grinding cabinet 1, a filter screen is installed inside the grinding cabinet 1, a mobile unit 2 is installed on the top of the filter screen, an electric telescopic rod 4 is installed on the top wall of the grinding cabinet 1, a suction cup 5 is connected to the bottom of the electric telescopic rod 4, a magnetic suction groove 3 is provided on the inner wall of the grinding cabinet 1, a side grinding unit 6 is slidably connected inside the magnetic suction groove 3, the side grinding unit 6 includes a magnetic bearing disk 61 slidably connected to the inside of the magnetic suction groove 3 and mutually attracted to the magnetic suction groove 3, the surface of the magnetic bearing disk 61 is connected to an internal hollow horizontal cylinder 63, a grinding ring 64 is fixedly sleeved on the tail end surface of the horizontal cylinder 63, a mobile grinding unit 7 is installed inside the grinding cabinet 1, the mobile grinding unit 7 includes a grinding disk 75, and the grinding disk 75 is arranged vertically to the grinding ring 64.

[0037] The mobile grinding unit 7 also includes a driving motor 71, the output end of the driving motor 71 is connected to a rotating rod, the top of the rotating rod is connected to the bottom center position of the grinding disk 75, the surface of the rotating rod is sleeved with a No. 1 bevel gear 72 located below the grinding disk 75, a cleaning ring 74 is embedded in the grinding ring 64, the interior of the cleaning ring 74 is penetrated by a connecting rod 8 extending to the interior of the horizontal cylinder 63, the surface of the connecting rod 8 is sleeved with a No. 2 bevel gear 73, and the No. 2 bevel gear 73 and the No. 1 bevel gear 72 are meshed with each other.

[0038] Specifically, the interior of the grinding cabinet 1 is installed with sound insulation material, which can effectively reduce noise interference during grinding;

[0039] During grinding, the sheet metal is first adsorbed on the bottom of the suction cup 5, and then the position of the sheet metal is adjusted by the electric telescopic rod 4 until the bottom of the sheet metal fits with the top of the grinding disc 75, and at this time, one side surface of the sheet metal fits with the surface of the grinding ring 64, and then the mobile grinding unit 7 is moved to one side below the sheet metal, and the drive motor 71 is started to drive the rotating rod and the grinding disc 75 to rotate, and at the same time, the cleaning ring 74 is driven to rotate under the meshing transmission of the first bevel gear 72 and the second bevel gear 73, and the grinding ring 64 is driven to rotate, and the grinding ring 64 is synchronously rotated by the interlocking connection between the cleaning ring 74 and the grinding ring 64, so that the side edge and the bottom partial surface of the sheet metal are polished and ground at the same time;

[0040] In addition, when the mobile grinding unit 7 moves along the longitudinal moving guide rail 23, the full grinding of the side edges can be completed, reducing the existence of grinding the four corners;

[0041] When the subsequent grinding area gradually moves to the right, the cleaning ring 74 is separated from the grinding ring 64. At this time, the grinding ring 64 stops grinding, and the grinding disc 75 continues to grind the bottom surface of the sheet metal. After the bottom grinding is completed, the sheet metal is turned over and the above operation is repeated to complete the grinding of the top and the other side of the sheet metal. This effectively reduces the actual number of grinding times, simplifies the grinding and polishing process, and can also achieve the purpose of energy saving and environmental protection by reducing driving costs.

[0042] The top of the driving motor 71 is connected to a bracket 10 , the top end of the bracket 10 is connected to a bearing sleeve, and the bearing sleeve is externally connected to the outer surface of the connecting rod 8 .

[0043] Specifically, the bracket 10 is used to support the connecting rod 8 and ensure the normal rotation of the connecting rod 8 with the help of the bearing sleeve.

[0044] A gear ring 62 is installed on the inner wall of the horizontal cylinder 63, and the length of the gear ring 62 is smaller than the length of the horizontal cylinder 63. The rear end surface of the connecting rod 8 is connected to a gear sleeve 9 that meshes with the gear ring 62, and the gear sleeve 9 is located on the inner side of the gear ring 62.

[0045] Specifically, when the cleaning ring 74 is engaged with the grinding ring 64, the gear sleeve 9 is meshed with the gear ring 62, and the transverse cylinder 63 connected to the gear ring 62 is driven by the connecting rod 8 to rotate synchronously, and the setting of the magnetic bearing disk 61 will not interfere with the rotation of the transverse cylinder 63.

[0046] The top tangent point of the cleaning ring 74 is at the same height as the top of the grinding disc 75 , and the cleaning ring 74 is located outside the grinding disc 75 .

[0047] Specifically, the equal height design allows the cleaning ring 74 to be separated from the grinding ring 64 and the grinding surface of the sheet metal part to be cleaned synchronously with the rotation of the connecting rod 8 .

[0048] An electromagnetic ring 641 is installed inside the grinding ring 64 . The cleaning ring 74 includes a magnetic disk 742 that attracts the electromagnetic ring 641 . A cleaning sponge ring 741 is sleeved on the outer surface of the magnetic disk 742 .

[0049] Specifically, when the electromagnetic ring 641 is activated, it attracts the magnetic disk 742 to strengthen the connection stability between the cleaning ring 74 and the grinding ring 64, and avoids the single interlocking connection that causes the cleaning ring 74 to be unable to effectively drive the grinding ring 64 to rotate when rotating.

[0050] The movable unit 2 includes a transverse movable guide rail 21 installed on the top of the filter screen plate, the interior of the transverse movable guide rail 21 is slidably connected to a sliding block 22, the top of the sliding block 22 is fixedly connected to a longitudinal movable guide rail 23, the interior of the longitudinal movable guide rail 23 is slidably installed with a sliding block 24, and the top of the sliding block 24 is connected to the bottom of the driving motor 71.

[0051] Specifically, the cooperation between the transverse moving guide rail 21 and the longitudinal moving guide rail 23 enables the driving motor 71 to achieve longitudinal and transverse movement with the cooperation of the first sliding block 22 and the second sliding block 24, thereby comprehensively grinding and cleaning the surface of the sheet metal part.

[0052] Second implementation method:

[0053] Figure 8-10 , wherein the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment, and for the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that a rotating disk 76 is fixedly sleeved on the surface of the connecting rod 8, an isolation tape is wound on the surface of the rotating disk 76, and the isolation tape is made of environmentally friendly material, and the rotating disk 76 is located between the cleaning ring 74 and the grinding ring 64.

[0054] The inner wall of the grinding ring 64 is coated with a non-stick coating, and the thickness of the grinding ring 64 is equal to the sum of the thicknesses of the turntable 76 and the cleaning ring 74 .

[0055] Specifically, after the cleaning ring 74 is cleaned, there is floating dust inside the grinding cabinet 1. To prevent the floating dust from adhering to the surface of the cleaned sheet metal again, as the cleaning ring 74 is separated from the inside of the grinding ring 64, the turntable 76 and the isolation tape on its surface are simultaneously separated, and at this time, the end of the isolation tape is in an outward-turned state, which can be quickly bonded to the surface of the cleaned sheet metal, thereby effectively isolating the surface of the sheet metal and enhancing the cleaning and maintenance effect;

[0056] The provision of the non-stick coating can prevent the outward-turned end of the isolation tape from adhering to the inner wall of the grinding ring 64 when the cleaning ring 74 is buckled on the inner wall of the grinding ring 64, thereby affecting the subsequent bonding and covering use.

[0057] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
