DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A burr grinding device for steel products in this embodiment is used to adjust the use angle of the grinding mechanism 3 according to the inclination angle, bend or inner corner grinding treatment on different steel products, so that it can complete the grinding without swinging the grinder, thereby achieving the effect of facilitating grinding.

[0023] Specifically, it includes a handle 1, a rotating mechanism 2 and a grinding mechanism 3;

[0024] Two switches 4 are embedded in the front of the handle 1, a mounting frame 5 is provided on the top of the handle 1, and two indicator lights 6 are provided on the front of the mounting frame 5;

[0025] The rotating mechanism 2 is arranged on the top of the mounting frame 5 and is used to drive the grinding mechanism 3 to rotate so as to adjust the use angle of the grinding mechanism 3;

[0026] The grinding mechanism 3 is arranged on the rotating mechanism 2 and is used for grinding the surface of the steel product after coming into contact with the steel product.

[0027] In this embodiment, when needed, the rotating mechanism 2 and the grinding mechanism 3 can be driven respectively by two switches 4. After the grinding mechanism 3 is powered on and in contact with the steel product, it can grind the surface of the steel product. After the rotating mechanism 2 is powered on, the use angle of the grinding mechanism 3 can be adjusted, so that the use state of the grinding mechanism 3 can be adjusted according to the corners on the steel product, making it convenient for the grinding mechanism 3 to extend into it for grinding it.

[0028] Specifically, refer to Figure 1The rotating mechanism 2 includes: a U-shaped frame 21, the U-shaped frame 21 is arranged on the top of the mounting frame 5, a servo motor 22 is arranged inside the U-shaped frame 21, and a driving rod 23 is arranged on the left side of the U-shaped frame 21. The right end of the driving rod 23 passes through the U-shaped frame 21 and is rotatably connected to the U-shaped frame 21. The right end of the driving rod 23 is connected to the servo motor 22 through a coupling 24. The servo motor 22 is used to drive the driving rod 23 to drive the grinding mechanism 3 to rotate an angle.

[0029] In this embodiment, when the servo motor 22 is powered on, it can drive the coupling 24, the drive rod 23 and the grinding mechanism 3 to rotate in sequence, so that it can adjust the use state of the grinding mechanism 3 according to the corners on the steel product, making it easier for the grinding mechanism 3 to extend into it for grinding.

[0030] Specifically, refer to Figure 2-3 The grinding mechanism 3 includes: a rotating frame 31, the rotating frame 31 is connected to the left end of the driving rod 23, a supporting frame 32 arranged above the rotating frame 31, the supporting frame 32 and the rotating frame 31 are adjustably connected through a connecting piece 33, a rotating rod 34 rotatably arranged inside the rotating frame 31 and the supporting frame 32, a pulley 35 sleeved on the outer wall of the rotating rod 34, a grinding transmission belt 36 sleeved on the outer walls of the two pulleys 35, and a servo motor 37 arranged on the left side of the rotating frame 31. The output shaft of the servo motor 37 is connected to the lower rotating rod 34, and the servo motor 37 is used to drive the lower rotating rod 34 to rotate. The two pulleys 35 are driven by the grinding transmission belt 36, and the lower rotating rod 34 is used to drive the lower pulley 35 and the grinding transmission belt 36 to rotate, and the rotating grinding transmission belt 36 is used to grind the surface of the steel product after contacting the steel product.

[0031] In this embodiment, when the servo motor 2 37 is powered on, the lower rotating rod 34 is driven to rotate and drive the lower pulley 35. During this process, the upper pulley 35 can be driven to rotate through the transmission function of the grinding transmission belt 36. When the rotating grinding transmission belt 36 contacts the surface of the external steel product, its surface can be polished.

[0032] Specifically, refer to Figure 3 The connecting member 33 includes two limit frames 331, the two limit frames 331 are arranged above the rotating frame 31, a sliding frame 332 is arranged between the two limit frames 331, and a fixing screw 333 is arranged on the front and rear sides of the sliding frame 332. The sliding frame 332 can be slid between the two limit frames 331, and the fixing screw 333 is used to fix the sliding frame 332. When the sliding frame 332 slides downward between the two limit frames 331, the distance between the rotating frame 31 and the supporting frame 32 can be adjusted to allow the two pulleys 35 to be brought closer to make the grinding transmission belt 36 weak, and the grinding transmission belt 36 can be replaced.

[0033] In this embodiment, after the outer wall of the grinding transmission belt 36 is used, the two fixing screws 333 can be screwed in reverse to cancel the fixed state between the sliding frame 332 and the two limit frames 331, and then the sliding frame 332 can be pulled downward to allow the two pulleys 35 to move closer to make the grinding transmission belt 36 loose, and the grinding transmission belt 36 can be replaced.

[0034] Specifically, refer to Figure 3 The limiting frame 331 is a square frame structure, and the bottom of the sliding frame 332 extends into the internal sliding grooves of the two limiting frames 331.

[0035] In this embodiment, when the sliding frame 332 can slide downward, since its bottom slides in the limiting frame 331, the slots therebetween cooperate to limit and guide the moving limiting frame 331, thereby improving stability during movement.

[0036] Specifically, refer to Figure 1 The two switches 4 are electrically connected to the two indicator lights 6 respectively, and the two switches 4 are electrically connected to the servo motor 1 22 and the servo motor 2 37 respectively.

[0037] In this embodiment, when the two switches 4 are turned on respectively, the two indicator lights 6 can respectively display the working status of the servo motor 1 22 and the servo motor 2 37 so that the staff can understand the use status information of the device.

[0038] Specifically, refer to Figure 2 , the diameter of the lower pulley 35 is greater than the diameter of the upper pulley 35.

[0039] In this embodiment, since the upper pulley 35 is relatively small in size, when in use, the upper pulley 35 can be extended into a narrow corner for grinding, to prevent the pulley 35 from being too large to be easily extended into the corner.
