Detailed Implementation

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-7As shown, a rust removal device for metal surface treatment includes: a base plate 1, a bracket 101 mounted on the top of the base plate 1, four clamping blocks 102 arranged inside the bracket 101, a grinding disc 103 arranged between the four clamping blocks 102, a rotating component arranged on one side of the outer end of the clamping blocks 102 for adjusting the use angle of the clamping blocks 102, the rotating component including: a rotating ring 2, teeth 201, a servo motor 202 and a gear 203, and a dust removal component arranged at the bottom of the grinding disc 103 for dust removal during metal grinding, the dust removal component including: a dust collection frame 4, a dust collection box 401, an air pump 402 and an air extraction pipe 403.

[0023] The base plate 1 has rotating rings 2 on both sides of its top, with teeth 201 on the outer side of each rotating ring 2. Servo motors 202 are mounted on both sides of the inner wall of the bracket 101. A gear 203 is connected to one side of the outer end of each servo motor 202 via a motor shaft. The gear 203 meshes with the teeth 201. When the two ends of the metal column are clamped between the four mating blocks 302, two servo motors 202 can be simultaneously activated via the control panel on one side of the outer end of the bracket 101. Each servo motor 202 is driven by a motor shaft. The two gears 203 rotate, and the two gears 203 then drive the rotating ring 2 and the clamping ring 3 to rotate through the teeth 201 respectively. Since the bonding block 302 and the clamping block 102 are installed inside the rotating ring 2 through the electric telescopic rod 301, the bonding block 302 and the metal column it clamps can rotate synchronously with the clamping ring 3, thereby adjusting the grinding angle of the metal column. One side of the rotating ring 2 is rotatably connected to the bracket 101 through the bearing, so one side of the rotating ring 2 can be supported and the rotating ring 2 can be rotated.

[0024] The device includes two rotating rings 2, each with a clamping ring 3 connected to its inner side. Each clamping ring 3 has an electric telescopic rod 301 mounted on its top and bottom. One end of the electric telescopic rod 301 is connected to a clamping block 102. A fitting block 302 is connected to the inner side of the clamping block 102. Openings 303 are provided on both sides of the outer end of the bracket 101. When using this device, one end of a metal column is passed through the opening 303, the rotating ring 2, and the clamping ring 3 until both ends of the metal column are positioned between the four fitting blocks 302. Then, the electric telescopic rod 301 drives the clamping block 102 and the fitting blocks 302 to rise and fall until one side of the fitting block 302 is raised and lowered to fit against the metal column, thus fixing both ends of the metal column between the four fitting blocks 302. The fitting blocks 302 are made of rubber to prevent damage to the metal column from clamping.

[0025] The grinding disc 103 has dust collection frames 4 on both sides of its bottom, and a dust collection box 401 is installed on the top of the base plate 1. Both sides of the outer end of the dust collection box 401 are equipped with air pumps 402. The top of the dust collection box 401 is connected to two air extraction pipes 403. When the grinding disc 103 grinds the metal column, dust is generated. At this time, the air pumps 402 extract air from the inside of the dust collection box 401, making the inside of the dust collection box 401 a low-pressure state. Therefore, the dust collection frames 4 can be extracted through the air extraction pipes 403, the diversion pipes 501 and the connecting pipes 5. Since the dust collection frames 4 are located on both sides of the bottom of the grinding disc 103, the dust collection frames 4 suck the dust generated when grinding the metal column into its interior and transport the dust to the inside of the dust collection box 401 through the air extraction pipes 403, the diversion pipes 501 and the connecting pipes 5.

[0026] Each of the two dust collection frames 4 has three connecting pipes 5 connected to one side of its outer end. Each of the two dust collection frames 4 has a diversion pipe 501 at its bottom. One end of each of the six connecting pipes 5 is connected to one of the two diversion pipes 501. The bottom ends of the two suction pipes 403 are connected to the two diversion pipes 501 respectively. The suction pipes 403 are made of flexible hose material. Therefore, when the dust collection frames 4 are raised or lowered, the suction pipes 403 will not affect the raising or lowering of the dust collection frames 4.

[0027] The dust collector 401 is equipped with a collection frame 6 inside. Both sides of the outer end of the collection frame 6 are connected to baffles 601. One side of the outer end of the baffle 601 has an opening, and an interception net 602 is installed inside the opening. When dust enters the dust collector 401, it is intercepted by the interception net 602 and then collected through the collection frame 6. The outer end of the collection frame 6 is connected to a mounting plate, which is bolted to the dust collector 401. Therefore, the mounting plate is easy to install and remove, allowing the collection frame 6 and the baffles 601 to be removed from the inside of the dust collector 401, thus facilitating the cleaning of dust inside the dust collector 401 and dust on the interception net 602.

[0028] The bracket 101 has an electric push rod 7 installed at the top, a lifting plate 701 installed at the bottom of the electric push rod 7, a motor 702 installed at the bottom of the lifting plate 701, and a rotating disk 703 driven by the motor shaft at the bottom of the motor 702. The two outer sides of the lifting plate 701 are connected to the two dust collection frames 4 by drive plates 704. After the metal column is fixedly installed between the four bonding blocks 302, the electric push rod 7 drives the lifting plate 701, the motor 702 and the rotating disk 703 to rise and fall. Since the rotating disk 703 is installed with the grinding disk 103 by bolts and nuts, the grinding disk 103 can rise and fall with the rotating disk 703 until the bottom of the grinding disk 103 is in contact with the metal column. At this time, the motor 702 drives the grinding disk 103 to rotate, and the surface of the metal column is ground by the rotation of the grinding disk 103. When the lifting plate 701 rises and falls, the dust collection frames 4 can be raised and lowered synchronously by the drive plates 704, thereby ensuring the dust collection effect of the dust collection frames 4.

[0029] Working principle:

[0030] When using this device, one end of the metal column is passed through the opening 303, the rotating ring 2, and the clamping ring 3 until both ends of the metal column are positioned between the four bonding blocks 302. Then, the clamping block 102 and the bonding blocks 302 are raised and lowered by the electric telescopic rod 301 until one side of the bonding block 302 is raised and lowered to fit against the metal column, thus fixing both ends of the metal column between the four bonding blocks 302. Next, the lifting plate 701, the motor 702, and the rotating disk 703 are raised and lowered by the electric push rod 7. Since the rotating disk 703 is installed with the grinding disk 103 by bolts and nuts, the grinding disk 103 can rise and fall with the rotating disk 703 until the bottom of the grinding disk 103 fits against the metal column. At this time, the grinding disk 103 is rotated by the motor 702, and the surface of the metal column is ground by the rotation of the grinding disk 103. Since the grinding disk 103 produces powder when grinding the metal column, the grinding process generates powder. Dust is drawn from the dust collection box 401 by the air pump 402, creating a low-pressure environment inside the dust collection box 401. This allows the suction frame 4 to be drawn from the dust collection pipe 403, the diversion pipe 501, and the connecting pipe 5. The suction frame 4, located on both sides of the bottom of the grinding disc 103, draws in the dust generated during the grinding of the metal column and transports it to the dust collection box 401 via the air pump 403, diversion pipe 501, and connecting pipe 5. Once inside the dust collection box 401, the dust is intercepted by the intercepting net 602 and collected by the collecting frame 6. A mounting plate is attached to one side of the outer end of the collecting frame 6, bolted to the dust collection box 401. This mounting plate facilitates easy disassembly and removal, allowing the collecting frame 6 and the baffle 601 to be removed from inside the dust collection box 401, thus facilitating the cleaning of the dust inside the dust collection box 401 and the dust on the intercepting net 602.
