Description

Technical Field

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

[0002] In order to facilitate the processing and transportation of aluminum materials, after the scrap aluminum is recycled, it is usually necessary to re-melt it and pour it into a mold to be processed into an aluminum plate. The surface of the aluminum plate formed inside the mold is usually rough, and a grinding device is needed to grind the surface of the aluminum plate before use.

[0003] In the prior art, the grinding device for aluminum plates is usually composed of a motor, a grinding wheel, a grinding platform and a clamping component. When in use, the aluminum plate is first clamped and fixed on the grinding platform by the clamping component, and then the motor drives the grinding wheel to rotate to grind the surface of the aluminum plate. Since the aluminum plate cannot be adsorbed and fixed by a magnet, and also cannot be fixed by a suction cup due to its rough surface, it can only be clamped and fixed by the edge of the aluminum plate. The traditional grinding device usually uses a screw rod to directly push the clamping plate to move to achieve the clamping of the component. This fixing method requires the operator to use a large force to turn the screw rod, which puts a heavy workload on the operator. At the same time, the thrust of the screw rod and the clamping force of the component are in the same direction. During the grinding process, the component is prone to loosening due to the shaking of the device. Utility Model Content

The upper part of the workbench 1 is provided with two front-to-back symmetrical vertical plates 11, and a grinding wheel 15 is rotatably arranged between the two vertical plates 11, and the grinding wheel 15 is used for grinding aluminum plates. As a preferred embodiment, Figure 1 and Figure 4 As shown, a guide opening 13 is provided in the middle of each vertical plate 11, and a first slider 14 is slidably provided inside the guide opening 13.

[0026] When grinding the aluminum plate, the aluminum plate is placed above the workbench 1, and the spline shaft 20 is driven to rotate by the second motor 21. The spline shaft 20 drives the second bevel gear 19 to rotate, and the second bevel gear 19 drives the grinding wheel 15 to rotate through the first bevel gear 17. Then, the first slider 14 is pushed to slide downward along the guide opening 13 by the electric push rod 16.

At this time, the grinding wheel contacts the aluminum plate and pushes the aluminum plate, so that the aluminum plate passes under the grinding wheel 15, thereby grinding the aluminum plate.

[0027] The second embodiment of the utility model refers to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a material frame 4 is slidably arranged on the upper part of the workbench 1 through a slide rail 3, and a positioning mechanism for fixing the aluminum plate is arranged on the inner left side of the material frame 4, and the positioning mechanism includes a positioning plate 5, which is slidably arranged on the inner left side of the material frame 4.

Preferably, fixed blocks 6 are fixedly provided at both ends of the upper surface of the workbench 1, a screw rod 7 is rotatably provided between the two fixed blocks 6, a traction block provided at the lower part of the material frame 4 is threadedly connected to the screw rod 7, a passive pulley 8 is provided at the right end fixed sleeve of the screw rod 7, a first motor 10 is provided in the middle of the rightmost support plate 2, a driving pulley 9 is provided at the right end fixed sleeve of the output shaft of the first motor 10, and the driving pulley 9 is connected to the passive pulley 8 by belt drive.

[0028] When grinding the aluminum plate, the aluminum plate is placed inside the material frame 4, and a socket wrench is used to rotate the bidirectional screw 25 through the six-sided column 28, so that the two control arms 27 slide outward along the front and rear ends of the bidirectional screw 25 respectively, so that the angle between the two adjacent adjustment arms 26 is increased, and then the positioning plate 5 is pushed to slide to the right, and the aluminum plate is clamped and fixed by the mutual extrusion of the positioning plate 5 and the right side plate of the material frame 4.

Subsequently, driven by the first motor 10, the active pulley 9 drives the passive pulley 8 to rotate through the belt, and the passive pulley 8 drives the screw 7 to rotate, so that the material frame 4 moves along the slide rail 3 with the internal aluminum plate, so that the aluminum plate passes through the rotating grinding wheel 15, and the grinding operation of the aluminum plate is realized.

[0029] When grinding a thinner aluminum plate, since the thickness of the aluminum plate is less than the height of the side of the material frame 4, when the aluminum plate is placed inside the material frame 4, the upper surface of the aluminum plate is lower than the upper surface of the material frame 4. At this time, the aluminum plate cannot be ground.
