[0033] See also Figure 6 and Figure 7 The grinding member 205 includes a fixing plate 216, both sides of which are fixedly connected with connecting columns 210, the connecting columns 210 are fixedly connected to the fixing plate 204, the fixing plate 216 is fixedly connected with the motor 206, both sides of the motor 206 are provided with limit plates 215, one end of the limit plate 215 away from the motor 206 is fixedly connected with a guide rod 213, the guide rod 213 passes through the fixing plate 216, the outer side of the guide rod 213 is provided with a spring 214, one end of the spring 214 is fixedly connected to the fixing plate 216, the spring 214 One end away from the fixed plate 216 is fixedly connected to the connecting rod 209, one end of the guide rod 213 away from the motor 206 is fixedly connected to the connecting rod 209, the center of the connecting rod 209 is fixedly connected to a connecting column 211, one end of the connecting column 211 away from the connecting rod 209 is rotatably connected to the grinding disc 212, the connecting column 211 is slidably connected to the connecting column 210, and one side of the connecting rod 209 away from the fixed plate 216 is fixedly connected to two fixing rods 208, and one end of the fixing rod 208 away from the connecting rod 209 is rotatably connected to the guide wheel 207.

[0034] Specifically, when the grinding assembly 2 is started, the motor 206 will start and control the grinding disc 212 to rotate, thereby grinding the columnar steel, and the grinding piece 205 as a whole will continue to rotate with the rotation of the rotating disc 202. During the rotation process, when the diameter of the columnar steel needs to change in an area, the columnar steel will apply a reaction force to the guide wheel 207, and then through force transmission, the connecting rod 209 will move toward the direction of the fixed plate 216, and then drive the spring 214 to move toward the direction of the fixed plate 216, so that the guide rod 213 is in a compressed state, and at the same time, when the connecting rod 209 rises, it will also drive the connecting column 211 to rise synchronously, ensuring that the grinding disc 212 can always be in contact with the columnar steel, and its contact pressure will not change significantly, so that the grinding disc 212 can change with the diameter change of the columnar steel.

[0035] See also Figure 8 and Fig. 9 A movable ring 223 is provided inside the fixed disk 204, and the movable ring 223 is coaxial with the fixed disk 204. A gear ring 217 is rotatably connected inside the movable ring 223. Several gears 218 are provided on the gear ring 217. The gear 218 corresponds to the position of the grinding piece 205.

[0036] Specifically, the rotating ring 203 will rotate under the action of the threaded rod 103 during the movement, thereby driving the fixed disk 204 to rotate. The rotation of the fixed disk 204 will cause the grinding piece 205 to rotate synchronously, so that the grinding piece 205 can rotate to grind the columnar steel. When the grinding assembly 2 starts to work, the motor 221 will start and drive the gear ring 217 to rotate through the transmission gear. The rotation of the gear ring 217 will cause all the gears 218 to rotate synchronously, and then all the threaded rods 219 will rotate synchronously. The rotation of the threaded rod 219 will drive the connecting block 220 to move, so that the grinding piece 205 can move to contact the columnar steel, so that the grinding piece 205 can grind the columnar steel.

[0037] See also Figure 4 and Figure 5 The working box 1 includes a fixed plate 102, and the fixed plate 102 is internally rotatably connected with a screw rod 101 and a screw rod 104. The screw rod 101 and the screw rod 104 are both threadedly connected to the connecting block 224. A threaded rod 103 is arranged above the screw rod 101.

The screw rod 101 and the screw rod 104 are driven by the same driving motor, and the driving motor is located inside the fixed plate 102.

[0038] Specifically, when the device is started, the driving motor controls the screw rod 101 and the screw rod 104 to rotate simultaneously, and then the grinding component 2 can drive the clamping component 103 on one side to move through the action of the thread. When the grinding component 2 moves to contact with the first controller 6, the clamping component 103 connected to the grinding component 2 will be powered off, so that the clamping component 103 stays in place to perform clamping work. At the same time, the electric lifting and retracting platform 103 and the electric telescopic platform 503 closest to the grinding component 2 will retract, so that the grinding component 2 can pass smoothly. The electric lifting and retracting platform 1 403 and the electric telescopic platform 503 are located between the electric lifting and retracting platform 1 and the electric telescopic platform 503, and the grinding component 2 will start working synchronously to grind the columnar steel. When the grinding component 2 moves to the next controller 6, the first electric lifting and retracting platform 1 403 and the electric telescopic platform 503 will extend to continue to press the columnar steel, while the second electric lifting and retracting platform 1 403 and the electric telescopic platform 503 will retract to reduce interference with the movement of the grinding component 2. When the grinding component 2 continues to move to the last controller 6, the second electric lifting and retracting platform 1 403 and the electric telescopic platform 503 will retract to reduce interference with the movement of the grinding component 2. The telescopic table 503 will reset to press the columnar steel material, and the grinding component 2 will continue to work until it moves out of the columnar steel material and contacts the clamping component 3 on the other side. When the grinding component 2 contacts the clamping component 3 on the other side, the grinding component 2 will stop working and the electromagnets on the grinding component 2 and the clamping component 3 will be energized for adsorption, and the driving motor will reverse at this time, so that the grinding component 2 drives the clamping component 3 to move in the reverse direction to complete the above operation. In the process of reverse movement, when the grinding component 2 contacts the clamping component 3 on the other side, When the grinding component 2 contacts the original clamping component 3, the original clamping component 3 will stop working and be in a loose state. When the grinding component 2 drives the original clamping component 3 to move out of the columnar steel, the staff turns off the device. At this time, the clamping component 3 on the other side will stop clamping and be in a loose state, and by controlling the movement of the electric lifting and retracting platform 403, the electric lifting and retracting platform 403 can push the clamping component 3 on the other side to separate from the columnar steel, so that the columnar steel can flow out from the bottom of the working box 1, reducing the work of unloading.

[0039] See also Fig.10 and Fig.11The clamping component 13 includes a moving plate 301, and two linkage blocks 302 are fixedly connected to one side of the moving plate 301 close to the lower clamping component 4.

[0043] See also Figure 3The upper clamping assembly 5 includes a moving block 501, and there are two moving blocks 501 that are symmetrically distributed. Two openings 1 are arranged on the moving block 501, and each opening is threadedly connected with a bidirectional threaded rod 502.

The side of the moving block 501 close to the lower clamping assembly 4 is fixedly connected with an electric telescopic table 503, and the side of the electric telescopic table 503 away from the moving block 501 is fixedly connected with a clamping block. The bidirectional threaded rod 502 and the bidirectional threaded rod 401 share a driving motor 1, and the driving motor 1 is located inside the working box 1. By setting the clamping block, the clamping block can be embedded with the bearing platform, so that the device can be suitable for columnar steels of different diameters.

[0044] Specifically, before starting work, the staff starts the driving motor 1, which controls the two-way threaded rod 401 and the two-way threaded rod 1 502 to rotate simultaneously. The rotation of the two-way threaded rod 401 causes the two moving blocks 1 402 to move toward each other at the same time, and the rotation of the two-way threaded rod 1 502 causes the two moving blocks 2 501 to move toward each other at the same time, so that the moving block 2 501 can always correspond to the moving block 1 402. The staff controls the moving distance of the moving block 1 402 according to the length of the columnar steel material, so that the columnar steel material can be moved to the left and right sides of the moving block 1 402. The center of gravity of the columnar steel can be located between the two moving blocks 402, so that the moving block 402 can carry the columnar steel. When the staff places the columnar steel on the electric telescopic table 403, the device is started. At this time, the electric telescopic table 503 and the electric telescopic table 403 will extend synchronously to clamp and position the columnar steel. When the electric telescopic table 503 and the electric telescopic table 403 are in contact with the columnar steel at the same time, the columnar steel is pressed and the axis of the columnar steel coincides with the working axis of the grinding component 2.

[0045] Working principle of the present invention: before starting work, the staff starts the driving motor 1, and the driving motor 1 controls the two-way threaded rod 401 and the two-way threaded rod 1 502 to rotate simultaneously. The rotation of the two-way threaded rod 401 causes the two moving blocks 1 402 to move toward each other at the same time, and the rotation of the two-way threaded rod 1 502 causes the two moving blocks 2 501 to move toward each other at the same time, so that the moving block 2 501 can always correspond to the moving block 1 402. The staff controls the moving distance of the moving block 1 402 according to the length of the columnar steel, so that the center of gravity of the columnar steel can be located between the two moving blocks 1 402, so that the moving block 1 402 can carry the columnar steel. When the staff places the columnar steel on the electric lifting and retracting platform 1 403 , start the device, at this time the electric telescopic table 503 and the electric lifting and retracting table 1 403 will be extended synchronously to clamp and position the columnar steel. When the electric telescopic table 503 and the electric lifting and retracting table 1 403 are in contact with the columnar steel at the same time, the columnar steel is pressed and the axis of the columnar steel coincides with the working axis of the grinding component 2. When the device is started, the driving motor will control the screw rod 101 and the screw rod 104 to rotate at the same time, and then through the action of the thread, the grinding component 2 can drive the clamping component 1 3 on one side to move. When the grinding component 2 moves to contact with the first controller 6, the clamping component 1 3 connected to the grinding component 2 will be powered off, so that the clamping component 1 3 stays in place to perform clamping work, and at the same time the electric lifting device closest to the grinding component 2 The retracting platform 403 and the electric telescopic platform 503 will retract, so that the grinding component 2 can pass smoothly between the electric retracting platform 403 and the electric telescopic platform 503, and the inside of the grinding component 2 will start working synchronously to grind the columnar steel. When the grinding component 2 moves to the next controller 6, the first electric retracting platform 403 and the electric telescopic platform 503 will extend to continue to press the columnar steel, while the second electric retracting platform 403 and the electric telescopic platform 503 will retract to reduce interference with the movement of the grinding component 2. When the grinding component 2 continues to move to the last controller 6, the second electric retracting platform 403 and the electric telescopic platform 503 will reset to press the columnar steel, and the grinding component 2 continues to work. The grinding assembly 2 is operated until it moves out of the columnar steel and contacts with the clamping assembly 3 on the other side. When the grinding assembly 2 contacts with the clamping assembly 3 on the other side, the grinding assembly 2 will stop working and the electromagnets on the grinding assembly 2 and the clamping assembly 3 will be energized for adsorption. At this time, the driving motor will reverse, so that the grinding assembly 2 drives the clamping assembly 3 to move in the opposite direction to complete the above operation. During the reverse movement, when the grinding assembly 2 contacts with the original clamping assembly 3, the original clamping assembly 3 will stop working and be in a loose state. After the grinding assembly 2 drives the original clamping assembly 3 to move out of the columnar steel, the staff turns off the device. At this time, the clamping assembly 3 on the other side will stop clamping and be in a loose state.By controlling the movement of the electric telescopic platform 403, the electric telescopic platform 403 can push the clamping assembly 3 on the other side to separate from the columnar steel, so that the columnar steel can flow out from the bottom of the working box 1, reducing the work of unloading.
