Description

Technical Field

[0001] The invention relates to a grinding device, in particular to a fine grinding device for steel plates. Background Art

[0002] Steel plate is a flat steel material formed by pouring molten steel and pressing it after cooling. It can be directly rolled or cut from wide steel strip.

[0003] After a long period of storage, the surface of the steel plate will rust. Before use, the surface rust needs to be polished and removed by a grinding device. Most of the existing square steel plate grinding devices can only grind the surface of the steel plate, and the grinding is not fine enough. The rust on the side of the steel plate still needs to be manually polished and removed, which is time-consuming and laborious. Therefore, we make improvements on this and propose a fine grinding device for steel plates. Summary of the invention

[0022] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fine grinding device for steel plates of the present invention comprises an operating table 1 and a fixed plate 2 fixedly arranged in the middle of the top of the operating table 1, clamping mechanisms 3 for clamping the steel plates are symmetrically arranged on both sides of the top of the fixed plate 2, a placing plate 4 for placing the steel plate is movably arranged in the middle of the top of the fixed plate 2, a grinding mechanism 5 for grinding the steel plate is arranged on the top of the fixed plate 2, inverted T-shaped slide grooves 6 are provided on both sides of the top of the operating table 1, and sliders are matched in the slide grooves 6, and the two sliders are fixedly arranged on both sides of the bottom of the grinding mechanism 5, respectively, and slots 7 connected with the slide grooves 6 are provided on both sides of the operating table 1, and a pushing mechanism 8 for pushing the grinding mechanism 5 is arranged in the slots 7.

[0023] Among them, the clamping mechanism 3 includes a clamping plate 301 and a threaded rod 302. A dovetail block is fixedly arranged in the middle of the bottom end of the clamping plate 301. The dovetail block is fitted into a dovetail groove 303 opened at the top end of the fixing plate 2. One end of the threaded rod 302 is rotatably connected to the dovetail block through a bearing. The other end of the threaded rod 302 passes through the dovetail groove 303 and is threadedly inserted therein. By turning the threaded rod 302 to drive its rotation, the threaded rod 302 moves to push the dovetail block to move along the dovetail groove 303. The movement of the dovetail block further drives the clamping plate 301 to move. By squeezing the two clamping plates 301 against each other, the position of the square steel plate is tightened.

[0024] Among them, a rotating shaft is fixedly arranged in the middle of the bottom end of the placing plate 4. The rotating shaft is rotatably connected to the fixing plate 2 through a bearing. Grooves are opened at the four corners and the middle of the top end of the placing plate 4. Suction cups 9 are arranged in the grooves. Place the square steel plate on the placing plate 4 and press the square steel plate. Through the provided suction cups 9, a certain adsorption force can be generated on the square steel plate. When the square steel plate is rotated, the placing plate 4 will rotate together, and thus the rotation of the square steel plate can be realized.

[0025] Among them, the grinding mechanism 5 includes a U-shaped movable plate 501, a lead screw 502, a servo motor 503 and two grinding discs 504. The two sides of the bottom end of the movable plate 501 are respectively fixedly connected to two sliders. The lead screw 502 is arranged at the top of the inner cavity of the movable plate 501, and both ends of the lead screw 502 are rotatably connected to the movable plate 501 through bearings. The servo motor 503 is fixedly arranged on one side of the movable plate 501, and the output shaft of the servo motor 503 passes through the movable plate 501 and is fixedly connected to the lead screw 502. Two movable blocks 505 are symmetrically and threadedly inserted along the center on both sides of the lead screw 502. Card slots are opened on the opposite sides of the bottom ends of the two movable blocks 505. The two grinding discs 504 are respectively arranged in the two card slots, and the grinding discs 504 are fixedly connected to the movable blocks 505 through bolts. Fixing blocks 506 are fixedly arranged at the top ends of the movable blocks 505. The same limiting rod 507 is slidably inserted into the two fixing blocks 506, and both ends of the limiting rod 507 are fixedly connected to the movable plate 501. The servo motor 503 is electrically connected to an external power supply through an external servo switch. When the servo motor 503 works, it drives the lead screw 502 to rotate. The self-rotation of the lead screw 502 drives the two movable blocks 505 threadedly connected thereto to move relatively along the lead screw 502. The movement of the movable blocks 505 drives the grinding discs 504 to move, and the two grinding discs 504 can be respectively moved to abut against both sides of the square steel plate.

[0026] Among them, the pushing mechanism 8 includes a pushing block 801, an electric push rod 802 and a connecting block 803. The pushing block 801 is placed in the slot 7, and one end of the pushing block 801 is fixedly connected to the slider, the connecting block 803 is fixedly connected to the operating table 1, the electric push rod 802 is fixed on the connecting block 803, and the output end of the electric push rod 802 is fixedly connected to the pushing block 801, and both electric push rods 802 are electrically connected to the external power supply through an external electric push rod switch. When the electric push rod 802 works, it pushes the pushing block 801 to move, and the movement of the pushing block 801 drives the slider to move. The movement of the slider drives the movable plate 501 to move along the slide groove 6, and the movement of the movable plate 501 drives the grinding sheet 504 to move, and the side of the square steel plate is ground by the grinding sheet 504.

[0027] During operation, the square steel plate with the polished surface is placed flat on the placement plate 4, and the square steel plate is pressed. The square steel plate is adsorbed and fixed to the placement plate 4 by the suction cup 9, and then the threaded rod 302 is twisted to drive it to rotate. The threaded rod 302 moves to push the dovetail block to move along the dovetail groove 303, and the dovetail block moves and then drives the clamping plate 301 to move. The two clamping plates 301 are squeezed against each other to achieve the position of the square steel plate being squeezed. Then the servo switch is turned on, and the servo motor 503 works to drive the screw rod 502 to rotate. The screw rod 502 rotates and drives the two movable blocks 505 threadedly connected to it to move relative to the screw rod 502. The movable block 505 moves and drives the grinding sheet 504 to move until the two grinding sheets 504 are respectively moved to conflict with the two sides of the square steel plate. At this time, the electric push rod switch is turned on, and the two electric push rods 80 2 works by reciprocating motion, the electric push rod 802 pushes the connecting block 803 to move back and forth, the movement of the connecting block 803 drives the slider to move back and forth along the slide groove 6, the movement of the slider drives the movable plate 501 to move, and then drives the grinding sheet 504 to move back and forth, and the grinding sheet 504 is used to grind both sides of the steel plate. After two sides of the square steel plate are grinded, the threaded rod 302 is rotated in the opposite direction, and the threaded rod 302 moves to drive the clamping plate 301 to move in the opposite direction, so that the clamping plate 301 is away from the square steel plate. At this time, the square steel plate is rotated, and the placement plate 4 and the square steel plate are rotated 180° through the rotating shaft provided. Through the above-mentioned grinding operation again, the other two sides of the square steel plate are ground. The servo motor 503 is preferably an HBS57 motor, and the electric push rod 802 is preferably an LX600 push rod.
