[0002] When metal sheets are processed, the reprocessing generally includes cutting, deburring, punching, bending, welding and other processes; burrs, welding slag, welding marks, sharp edges and other defects will be generated. People can use grinding methods to repair the defects to avoid problems such as burr punctures, sharp edge cuts, and mismatched overlapping positions caused by welding marks. In actual production, there are many types of metal sheets, with different thicknesses and sizes, and various shapes.

[0054] Embodiment 1

[0055] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, provides a plate grinding device.

[0056] In this embodiment, the grinding device includes a base frame 1, a grinding belt 2 and a pressure roller 3; when working, the workpiece is placed on the base frame 1, and the workpiece is driven to move by a driving force applied from the outside until the workpiece moves under the pressure roller 3. At this time, the workpiece is squeezed on the base frame 1 by the pressure roller 3. As the workpiece continues to move, the pressure roller 3 begins to rotate and the pressure roller 3 slides up a certain distance; then the workpiece and the grinding belt 2 are in sliding and squeezing contact, and the burrs, welding marks, welding slag and other defects on the surface of the workpiece are polished by the reciprocating grinding belt 2 until the surface of the workpiece is smooth and flat; with the squeezing of the pressure roller 3, the workpiece is prevented from slipping when the workpiece and the grinding belt 2 are in sliding and squeezing contact, resulting in incomplete grinding, thereby avoiding the occurrence of unqualified grinding and improving the consistency and stability of the workpiece grinding effect.

[0058] Reference Figure 1~Figure 3 , which is the second embodiment of the utility model. Compared with the first embodiment, this embodiment further adds an adjustment block 4, a spring 41, an adjustment rod 42 and an adjustment nut 43; the thrust provided by the spring 41 provides a driving force for the sliding of the adjustment block 4, so that an elastic force with adjustable size is formed between the clamping roller 3 and the workpiece, which is suitable for plates of different thicknesses, and avoids the clamping roller 3 from getting stuck after the thickness of the plate changes, thereby expanding the applicable scope of the grinding device. The initial position of the clamping roller 3 can be adjusted by rotating the adjustment nut 43 and the adjustment screw, so as to avoid the plate thickness size changing too much and exceeding the adjustment range of the existing state, resulting in grinding failure; if the plate thickness changes from small to large and there is a large change value, there is a stagnation between the edge of the plate and the clamping roller 3, resulting in the plate being unable to move smoothly to the bottom of the clamping roller 3, resulting in grinding failure; if the plate thickness changes from large to small and there is a large change value, the clamping roller 3 and the plate do not have extrusion contact, which will also cause grinding failure.

[0059] Embodiment 3

Compared with the first embodiment, this embodiment further sets the number of pressure rollers 3 to a plurality of numbers, preferably four in this embodiment, and two are respectively arranged on both sides of the grinding belt 2; with the help of the fixing of a plurality of pressure rollers 3, the stability of the plate during grinding is improved, and the plate is prevented from having the required external displacement, which causes grinding failure.

[0063] Embodiment 5

[0064] Reference Figure 1 and Figure 3, which is the fifth embodiment of the utility model. Compared with the first embodiment, this embodiment further adds a tensioning unit 6, which specifically includes a grinding frame 61, a grinding roller 62, a tensioning frame 63, a tensioning roller 64, a linear drive 1 65 and a linear drive 2 66; wherein the linear drive 1 65 and the linear drive 2 66 are both hydraulic cylinders driven by hydraulic pressure in the prior art; when working, after the model of the plate to be ground is determined, the linear drive 1 65 is started according to the thickness of the plate, and the grinding frame 61 is driven to slide up and down by the power output by the linear drive 1 65 until the positions of the grinding frame 61 and the grinding roller 62 move to appropriate positions, and the operation of the linear drive 1 65 is stopped; then the linear drive 1 65 is started The linear driver 2 66 drives the tensioning frame 63 and the tensioning roller 64 to slide upward with the help of the power output by the linear driver 2 66, until the grinding belt 2 on the tensioning roller 64 and the grinding roller 62 is in a taut state, and then stops the operation of the linear driver 2 66; at this time, the grinding roller 62 is driven to rotate with the help of an external power source, and the grinding belt 2 is driven by the grinding roller 62 to perform a circular motion and grind the workpiece; when the size of the workpiece changes, the linear driver 1 65 and the linear driver 2 66 can be started to adjust the position of the grinding belt 2 according to the thickness of the plate, thereby improving and ensuring the consistency of the grinding effect; when the thickness of the front and rear plates are inconsistent, the grinding effect of the grinding belt 2 is inconsistent, which increases the amount of rework.
