[0003] The existing method of grinding and removing rust from the surface of steel structures mainly relies on workers to use handheld grinders. When facing flat objects such as steel plates, it is relatively simple and feasible to use handheld grinders to grind and remove rust. However, when facing objects such as steel pipes, because the surface of the steel pipe is an arc surface, workers need to constantly change the grinding direction. Grinding and removing rust takes a long time and has poor effect. In view of this, we propose a device for grinding and removing rust on the surface of steel structures. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example:

[0021] This embodiment discloses a device for grinding and removing rust from the surface of a steel structure, see Figures 1 to 3 , including a workbench 1, a clamping mechanism 2 and a grinding mechanism 3.

[0022] like Figure 1 to Figure 2 As shown, the clamping mechanism 2 is arranged on the surface of the workbench 1.

[0023] Specifically, Figure 1 to Figure 2 As shown, the clamping mechanism 2 includes two symmetrically arranged bases 201 and a cylinder 202; the two bases 201 are symmetrically arranged at both ends of the workbench 1, and three-jaw chucks 203 are arranged on opposite sides of the two bases 201. The cylinder 202 is fixedly connected to one end of one of the three-jaw chucks 203, and the other end of the cylinder 202 is rotatably connected to one of the bases 201. One end of the other three-jaw chuck 203 is fixedly connected to a rotating shaft 204, and one end of the rotating shaft 204 is penetrated through the other base 201 and fixedly connected to a driven gear 205; a motor A206 is fixedly installed on one side of the other base 201 through a mounting plate, and a driving gear 207 is fixedly connected to the output end of the motor A206. The driving gear 207 is meshed with the driven gear 205. First, one end of the steel pipe is fixed by one of the three-jaw chucks 203. The cylinder 202 is driven by an external control mechanism. The cylinder 202 pushes one of the three-jaw chucks 203 and the steel pipe to approach the other three-jaw chuck 203 and then fixes the other end of the steel pipe by the other three-jaw chuck 203. The motor A206 is driven by the external control mechanism. The motor A206 drives the driving gear 207 to rotate. The driving gear 207 drives the other three-jaw chuck 203 to rotate through the driven gear 205 and the rotating shaft 204, thereby driving the steel pipe to rotate between the two bases 201, and then the surface of the steel pipe is polished and rust-removed by the polishing mechanism 3.

[0024] like Figures 1 to 3 As shown, the grinding mechanism 3 is arranged on the top of the clamping mechanism 2.

[0025] Specifically, Figures 1 to 3As shown, the grinding mechanism 3 includes a C-shaped mounting frame 301, a slide bar 302 and a telescopic rod 303; the two ends of the bottom of the C-shaped mounting frame 301 are respectively fixedly connected to the top surfaces of the two bases 201, a through slot 3011 is opened in the middle of the C-shaped mounting frame 301, one end of the slide bar 302 is passed through the through slot 3011 and is fixedly connected to a top plate 304, the bottom surface of the top plate 304 is fixedly connected to one end of the telescopic rod 303, a grinding block 305 is fixedly connected to the bottom of the telescopic rod 303, and a reciprocating assembly 301 is provided on the top of the C-shaped mounting frame 301. 6. A spring 307 is sleeved on the surface of the telescopic rod 303. The top of the spring 307 is fixedly connected to the top surface of the top plate 304, and the bottom of the spring 307 is fixedly connected to the top of the grinding block 305. After the steel pipe is fixed, the bottom surface of the grinding block 305 contacts the surface of the steel pipe, driving the telescopic rod 303 to contract, and the gap between the grinding block 305 and the top plate 304 is reduced. The spring 307 is compressed. Due to the elastic force of the spring 307, the spring 307 also applies a downward force to the grinding block 305, so that the grinding block 305 is close to the surface of the steel pipe.

[0026] Further, such as Figures 1 to 3 As shown, the reciprocating assembly 306 includes a motor B3061 and a cylindrical cam 3062. The motor B3061 is fixedly mounted on one end of the top surface of the C-shaped mounting frame 301 by screws. Both ends of the cylindrical cam 3062 are rotatably connected to both ends of the top surface of the C-shaped mounting frame 301 through mounting seats. One end of the cylindrical cam 3062 is fixedly connected to the output end of the motor B3061. A moving ring 3063 is sleeved on the surface of the cylindrical cam 3062. The inner wall of the moving ring 3063 is connected to the cylindrical cam 3062 through a slider. The slide groove on 062 is slidably connected, the outer wall of the bottom of the movable ring 3063 is fixedly connected to the top surface of the slide rod 302, and the motor B3061 is driven by the external control mechanism. The motor B3061 drives the cylindrical cam 3062 to rotate, and the cylindrical cam 3062 drives the movable ring 3063 to slide back and forth on the cylindrical cam 3062 through its own slide groove and the slider, driving the slide rod 302 to slide left and right in the through groove 3011 and then driving the grinding block 305 to move left and right to grind the rotating steel pipe.

[0027] Working principle: When the utility model is used, one end of the steel pipe is first fixed by one of the three-jaw chucks 203, and the cylinder 202 is driven by the external control mechanism. The cylinder 202 pushes one of the three-jaw chucks 203 and the steel pipe to approach the other three-jaw chuck 203, and then the other end of the steel pipe is fixed by the other three-jaw chuck 203. The motor A206 is driven by the external control mechanism, and the motor A206 drives the driving gear 207 to rotate. The driving gear 207 drives the other three-jaw chuck 203 to rotate through the driven gear 205 and the rotating shaft 204, and then drives the steel pipe to rotate between the two bases 201. After the steel pipe is fixed, the bottom surface of the grinding block 305 is in contact with the steel pipe. The contact with the pipe surface drives the telescopic rod 303 to contract, the gap between the grinding block 305 and the top plate 304 is reduced, and the spring 307 is compressed. Due to the elastic force of the spring 307, the spring 307 also applies a downward force to the grinding block 305, so that the grinding block 305 is close to the surface of the steel pipe, and the motor B3061 is driven by the external control mechanism. The motor B3061 drives the cylindrical cam 3062 to rotate. The cylindrical cam 3062 drives the moving ring 3063 to slide back and forth on the cylindrical cam 3062 through its own sliding groove and the slider, and drives the sliding rod 302 to slide left and right in the through groove 3011, thereby driving the grinding block 305 to move left and right, and grinding the rotating steel pipe.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
