An adjusting screw is connected to the internal bearing of the connecting shaft. Limiting posts are fixedly connected to both ends of the upper surface of the connecting base plate, and a connecting plate is sleeved on the outer surface of the two sets of limiting posts. The inner part of the middle position of the connecting plate is threadedly connected to the outer surface of the adjusting screw. An external power source can provide power to the first motor. After the first motor is started, it can drive the first grinding wheel to rotate. The adjusting screw can rotate inside the connecting shaft, and when the adjusting screw rotates, it can drive the connecting plate to move on the outer surface of the two sets of limiting posts. The setting of the two sets of limiting posts can prevent the connecting plate from rotating when moving.

[0011] Preferably, a second motor is mounted on the upper surface of the connecting plate, and a second grinding wheel is fixedly connected to the output end of the second motor. An external power supply can provide power to the second motor, and the second motor can drive the second grinding wheel to rotate after starting.

The two sets of limit wheels can then be used to fix both sides of the steel. Pulling two sets of connecting seats on the outer surfaces of the two sets of screws moves the rollers synchronously. Rotating the first and second fixing plates, which respectively adhere to the upper and lower surfaces of the two sets of connecting seats, fixes the positions of the connecting seats and the rollers. The rollers can then be used to fix the upper surface of the steel. This design allows the equipment to fix the steel during grinding. Furthermore, by providing power to the third motor via an external power source, starting the third motor drives the transmission wheel to rotate, thereby moving the steel.

A second support base 12 is provided at one end of the first support base 11. The first motor 13 is mounted on the surface of the opposite end of the first support base 11 and the second support base 12. The first grinding wheel 14 is fixedly connected to the output end of the first motor 13. A connecting base plate 15 is fixedly connected to the surface of the opposite side of the first support base 11 and the second support base 12. A connecting shaft 16 is fixedly connected to the middle position of the upper surface of the connecting base plate 15, and an adjusting screw 17 is connected to the internal bearing of the connecting shaft 16. Limiting posts 18 are fixedly connected to both ends of the upper surface of the connecting base plate 15, and connecting plates 19 are sleeved on the outer surfaces of the two sets of limiting posts 18. The interior of the middle position of the connecting plate 19 is threadedly connected to the outer surface of the adjusting screw 17. A second motor 110 is mounted on the upper surface of the connecting plate 19, and the output end of the second motor 110 is fixedly connected to... The second grinding wheel 111, the first support base 11, and the second support base 12 all have support legs at the four corners of their lower surfaces, which can improve the overall stability of the equipment during use. An external power supply can provide power to the first motor 13. After the first motor 13 is started, it can drive the first grinding wheel 14 to rotate. The adjusting screw 17 can rotate inside the connecting shaft 16, and when the adjusting screw 17 rotates, it can drive the connecting plate 19 to move on the outer surface of the two sets of limiting posts 18. The setting of the two sets of limiting posts 18 can prevent the connecting plate 19 from rotating during movement. An external power supply can provide power to the second motor 110. After the second motor 110 is started, it can drive the second grinding wheel 111 to rotate. When the first grinding wheel 14 and the second grinding wheel 111 rotate, they can grind the surface of the steel. This design allows the equipment to adjust the distance between the first grinding wheel 14 and the second grinding wheel 111 according to the size of the steel, thereby improving the practicality of the equipment to a certain extent.

[0026] Example 2

[0027] like Figures 4 to 6As shown, this embodiment also proposes a fixing structure 2, which includes a fixing seat 21, threaded posts 23, and limiting wheels 25. Two sets of threaded posts 23 and limiting wheels 25 are provided. The lower end of the fixing seat 21 is fixedly connected to the upper surface of the first support seat 11. A connecting groove 22 is provided inside the upper end of the fixing seat 21. Both sets of threaded posts 23 are inserted into the connecting groove 22. Limiting rings 24 are fixedly connected to the lower ends of both sets of threaded posts 23, and the upper surfaces of both sets of limiting rings 24 are attached to the lower surface of the upper end of the fixing seat 21. The upper ends of both sets of threaded posts 23 are bearing-connected to the limiting wheels 25. Threaded plates 26 are threadedly connected to the outer surfaces of both sets of threaded posts 23, and the lower surfaces of both sets of threaded plates 26 are attached to the fixing seat 21. On the upper surface of the fixed seat 21, two sets of threaded posts 23 can move inside the connecting groove 22. The two sets of limiting rings 24 prevent the two sets of threaded posts 23 from disengaging from the connecting groove 22. Rotating the two sets of limiting rings 24 allows them to move on the outer surfaces of the two sets of threaded posts 23 respectively. When the lower surfaces of the two sets of limiting rings 24 are in contact with the upper surface of the fixed seat 21, the positions of the two sets of threaded posts 23 can be fixed, thereby fixing the positions of the two sets of limiting wheels 25. When the two sets of limiting wheels 25 are in contact with the surfaces on both sides of the steel, the steel can be fixed. When the steel moves, it can drive the two sets of limiting wheels 25 to rotate on the upper ends of the two sets of threaded posts 23 respectively, thereby preventing the two sets of limiting wheels 25 from affecting the movement of the steel.

[0028] The transmission structure 3 includes a third motor 31, a support frame 34, and a roller 37. Two sets of support frames 34 are provided.

A transmission wheel 32 is fixedly connected to the output end of the third motor 31, and a connecting block 33 is bearing-connected to one end of the transmission wheel 32. The lower end of the connecting block 33 is fixedly connected to the upper surface of the first support base 11. The lower ends of both sets of support frames 34 are fixedly connected to the upper surface of the first support base 11, and a lead screw 35 is fixedly connected to the upper end of both sets of support frames 34. A connecting seat 36 is sleeved on the outer surface of each set of lead screws 35, and a roller 37 is bearing-connected to the outer surface of opposite ends of the two sets of connecting seats 36. A first fixing plate 38 and a second fixing plate 39 are threadedly connected to the outer surface of each set of lead screws 35. The upper surface of the first fixing plate 38 is respectively attached to the lower surface of the two sets of connecting seats 36, and the lower surface of the two sets of second fixing plates 39 is respectively attached to the upper surface of the two sets of connecting seats 36. When the two sets of connecting seats 36 are pulled to move on the outer surface of the two sets of lead screws 35, the roller 37 can be moved synchronously. When the two sets of first fixing plates 38 and second fixing plates 39 are rotated and respectively attached to the upper and lower surfaces of the two sets of connecting seats 36, the positions of the two sets of connecting seats 36 and roller 37 can be fixed. At this time, the upper surface of the steel can be fixed by the roller 37. After the third motor 31 is powered by an external power source, the third motor 31 can be started to drive the transmission wheel 32 to rotate. When the transmission wheel 32 rotates, it can drive the steel to move synchronously, and the steel can be fixed by the roller 37.

[0029] Working principle: When using the equipment, first place the steel on the upper surface of the transmission wheel 32, then pull the two sets of connecting seats 36 to drive the roller 37 to move synchronously, then the outer surface of the roller 37 is attached to the upper surface of the steel, then rotate the two sets of first fixing plates 38 and second fixing plates 39 respectively, and then make them attach to the upper and lower surfaces of the two sets of connecting seats 36 respectively. At this time, the position of the roller 37 is fixed. Then pull the two sets of threaded columns 23 respectively to drive the outer surface of the two sets of limit wheels 25 to attach to the surfaces on both sides of the steel, then rotate the two sets of limit rings 24 so that their lower surfaces are attached to the upper surface of the fixing seat 21. At this time, the position of the steel is fixed.

[0030] Next, rotating the adjusting screw 17 drives the connecting plate 19, the second motor 110, and the second grinding wheel 111 to move synchronously. Then, the second grinding wheel 111 is adjusted to a suitable height. Then, an external power supply provides power to the first motor 13, the second motor 110, and the third motor 31. After the third motor 31 starts, it drives the transmission wheel 32 to rotate. Then, the transmission wheel 32 moves the steel while rotating. After the first motor 13 and the second motor 110 start, they drive the first grinding wheel 14 and the second grinding wheel 111 to rotate respectively. At this time, the steel can be ground. The above is the complete working principle of this utility model.
