Description

Technical Field

[0001] The utility model relates to the technical field of metal plate processing, in particular to a grinding device for metal plate production and processing. Background Art

[0002] When processing metal sheets, it is usually necessary to grind their surfaces to remove burrs and other foreign matter on the surface, making them smooth and improving the quality.

[0003] The Chinese utility model patent with announcement number CN215999793U discloses a metal plate surface grinding device. In this case, the rapid grinding operation of the metal plate is realized through the cooperation of the table body, the grinding table and the grinding assembly. No manual operation is required during the grinding process, which greatly reduces the labor intensity of the workers and reduces the consumption of manpower. At the same time, compared with traditional manual grinding, it is more efficient and has better grinding quality. However, in actual use, it is impossible to grind both sides of the metal plate at the same time, and when grinding, it is not suitable for metal plates of different thicknesses. Its grinding efficiency needs to be further improved and its applicability is poor. Therefore, it is necessary to propose a grinding device for metal plate production and processing to solve the above problems. Utility Model Content

[0006] By adopting the above technical scheme, the positioning component fixes the metal plate to be polished on the fixed frame, and then controls the grinding discs on both sides to approach each other through the pusher to make them fit with the surface of the metal plate. The first motor controls the rotation of the rotating frame to make the three grinding discs on both sides rotate on the surface of the metal plate to polish it. The electric push rod controls the lifting of the grinding disc, and the linear electric guide rail makes the sliding plate slide back and forth, thereby controlling the forward and backward displacement of the grinding disc. The entire surface of the metal plate can be quickly polished, and both sides of the metal plate can be polished at the same time, and the polishing efficiency is higher.

[0007] The utility model is further configured as follows: sliders are fixedly installed at both ends of the linear electric guide rail, and sliding grooves adapted to the sliders are arranged at both left and right ends of the inner side of the movable frame.

[0008] By adopting the above technical solution, when the electric push rod pushes the linear electric guide rail to rise and fall, the sliders at both ends slide in the slide grooves, making the lifting and lowering displacement of the linear electric guide rail more stable.

[0009] The utility model is further configured as follows: the pushing member includes a second motor installed on the outer wall of the base frame, a bidirectional screw is installed at the output end of the second motor, two horizontal rods are installed in a front-to-back symmetrical manner in the inner cavity of the base frame, and the bottoms of the two movable frames are both threadedly connected to the bidirectional screw and slidably connected to the two horizontal rods.

[0010] By adopting the above technical solution, the second motor controls the rotation of the bidirectional screw rod, and under the limit of the horizontal rods on both sides, the movable frames at both ends are pushed to slide relative to each other, so that the grinding discs on both sides fit the surface of the metal plate, making the device suitable for grinding plates of different thicknesses.

[0011] The utility model is further configured as follows: the positioning component includes a positioning frame installed above the fixing frame, and the upper and lower ends of the inner side of the positioning frame are respectively provided with a first pressing groove and a second pressing groove, and the upper end surface of the first pressing groove is rotatably provided with a screw rod that threads through the positioning frame, and the upper end of the screw rod is installed with a handle.

[0012] By adopting the above technical solution, the metal plate is placed inside the positioning frame, and the screw is rotated by holding the handle to push the first pressing groove downward, so that the metal plate is fixed between the first pressing groove and the second pressing groove, thereby facilitating stable grinding of the metal plate.

[0013] The utility model is further configured as follows: a plurality of springs connected to the inner wall of the positioning frame are installed at the bottom of the second pressing groove, blocks are installed at both ends of the first pressing groove and the second pressing groove, and limiting grooves for the blocks to slide up and down are provided at both left and right ends of the inner wall of the positioning frame.

[0014] By adopting the above technical solution, the fixing effect of the metal plate is made more stable through the expansion and contraction rebound of the spring, and during the movement of the first pressing groove and the second pressing groove, the blocks at both ends slide in the limit grooves, making the lifting and lowering more stable.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model controls the rotation of the bidirectional screw by the second motor, and under the limit of the horizontal rods on both sides, pushes the movable frames at both ends to slide relatively, so that the grinding discs on both sides fit the surface of the metal plate, and controls the rotation of the rotating frame by the first motor, so that the three grinding discs on both sides rotate on the surface of the metal plate to grind it, and the electric push rod controls the lifting of the grinding disc, and the linear electric guide rail makes the sliding plate slide back and forth, thereby controlling the forward and backward displacement of the grinding disc, which can quickly grind the entire surface of the metal plate, and can grind both sides of the metal plate at the same time, and its grinding efficiency is higher.

[0017] 2. The utility model places the metal plate inside the positioning frame, holds the handle to rotate the screw, pushes the first pressing groove downward, and fixes the metal plate between the first pressing groove and the second pressing groove, thereby facilitating stable grinding of the metal plate. The grinding discs on both sides can be adjusted in position according to the thickness of the metal plate, so that the device can be suitable for processing plates of different thicknesses, and its applicability is stronger.
