[0052] Compared with the traditional positioning device, the positioning device for grinding metal plates according to the various embodiments of the present invention is more convenient for workers to grind the edges of metal plates, avoids frequent clamping of metal plates, improves work efficiency, and can completely grind the top surface of the metal plate after one positioning, reducing the labor intensity of workers and laying the foundation for batch grinding of metal plates.

[0053] In addition, because the adjusting rod is rotatably installed inside the connecting block, and a bidirectional thread is provided on the adjusting rod, and the adjusting rod is connected to two supporting seats, when the staff turns the adjusting rod clockwise, the supporting plate moves upward, and when the adjusting rod is turned counterclockwise, the supporting plate moves downward, which is convenient for the use of metal plates of different thicknesses, so that the top surface of the metal plate is higher than the top surfaces of the two protective plates, which is convenient for the staff to grind the edges of the metal plate, avoids frequent clamping of the metal plate, and improves work efficiency.

[0054] In addition, because two driving frames are fixedly installed on the top of the mounting frame, and the two driving frames are tightly fitted with the outer ends of the four driving blocks, when the staff starts the four hydraulic cylinders, the mounting frame drives the two driving frames to move downward. At this time, the two clamping plates move inward at the same time under the action of the two driving frames, which is convenient for quickly clamping the metal sheet on the top of the support plate, thereby realizing clamping on the left and right sides of the metal sheet and pressing on the top of the metal sheet, making the metal sheet more stable during grinding and improving the grinding quality of the metal sheet. A spring is installed between the two clamping plates and the two protective plates, so that the two protective plates can be automatically adjusted according to the size of the metal sheet on the premise of ensuring that the two pressing rollers are pressed against the metal sheet, thereby improving the versatility of the present invention.

[0055] In addition, after the grinding of the top center area of ​​the metal plate is completed, the staff can start the motor. Since drive shaft one is connected to the two sliding rods on the front side, and drive shaft two is connected to the two sliding rods on the rear side, and drive shaft two is connected to drive shaft one through a synchronous belt, when the staff starts the motor, the four sliding rods move inward at the same time under the action of drive shaft one and drive shaft two. At this time, the staff can grind the left and right sides of the top of the metal plate, so that the metal plate can be completely ground on the top surface after one positioning, avoiding the staff from frequently disassembling the metal plate, improving work efficiency, and reducing the labor intensity of the staff.

[0056] In addition, because the two L-shaped rods are fixedly connected to the two driving frames, and the two pressing blocks are slidably installed at the bottom of the two mounting frames, when the mounting frames move downward, the two sets of pressing devices are driven to move downward, so that when the two clamping rollers contact the metal plate, the two elastic blocks contact the two guide blocks under the action of the two pressing blocks, thereby reducing the movement of the two protective plates when the metal plate is polished, thereby improving the polishing accuracy of the metal plate. The setting of springs installed on the top of the two pressing blocks, on the one hand, allows the present invention to be used for metal plates of different thicknesses, thereby improving the versatility of the present invention, and on the other hand, when the two elastic blocks contact the two guide blocks, the two guide blocks still have a moving function, thereby ensuring the contact between the two clamping rollers and the metal plate and improving the positioning accuracy of the metal plate.

[0057] In addition, when the staff starts the motor and the four sliding rods move inward at the same time, the two cleaning rollers can automatically clean the residue on the top surface of the metal plate, avoiding the residue remaining on the bottom of the two pressing rollers after movement, so that the two pressing rollers are tightly fitted to the metal plate, thereby improving the positioning quality of the metal plate. The two connecting frames are rotatably connected to the two sliding rods, and the two connecting frames are fixedly installed with cleaning rollers. Even if the cleaning rollers are worn out due to long-term use, they can always fit with the metal plate under the action of gravity, thereby improving the cleaning quality of the residue on the top of the metal plate.
