Specific implementation method:

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a plate clamp for a surface grinder includes a workbench 1 on the surface grinder, a grinding piece is fixed on the workbench 1, the grinding piece adopts the existing technology, a clamping plate assembly is movably connected to the workbench 1, the clamping plate assembly can adjust the clamping space size according to the specifications of the plate 2, the clamping plate assembly is arranged on both sides of the grinding piece, and the plate 2 can be placed on the workbench 1 and placed in the clamping plate assembly.

[0020] During use, the plate 2 is placed directly on the workbench 1 and at the same time in the clamping plate assembly. Then, the adjustment function of the clamping plate assembly can be used to adjust according to the specifications of the plate 2. Finally, the plate 2 can be clamped stably, which can also ensure the precise processing of the plate 2 by the grinding part.

[0021] The clamping plate assembly includes two first clamping plates 3 arranged opposite to each other, and two positioning plates 4 are slidably connected to the first clamping plates 3. The two positioning plates 4 are respectively arranged on the front and rear sides of the first clamping plates 3. The bottom of the positioning plates 4 passes through the sliding hole 5 and is fixedly connected to the electromagnet block 6. The electromagnet block 6 is electrically connected to the external controller control. The sliding hole 5 is fixed on the workbench 1, and the positioning plates 4 can slide back and forth in the sliding hole 5.

[0022] The front side surface and the rear side surface of the first clamping plate 3 are respectively provided with key-shaped positioning holes 7 , a positioning screw 8 slides through the key-shaped positioning hole 7 , and a locking nut 9 is threadedly connected to the positioning screw 8 .

[0023] During use, the positioning plate 4 can be positioned and locked by utilizing the force of the positioning screw 8 and the locking nut 9. In this way, when the locking nut 9 is loosened, the positioning screw 8 loses its locking effect on the positioning plate 4. In this way, the first clamping plate 3 can be slid to adjust the height position of the first clamping plate 3 to suit the thickness of the plate 2. After the adjustment is completed, the locking nut 9 is tightened so that the positioning screw 8 can lock the positioning plate 4 in position;

[0024] At the same time, because the external controller can control the electromagnet block 6 to start, the electromagnet block 6 can be adsorbed under the workbench 1 to achieve further positioning of the positioning plate 4, which can ensure the stable clamping effect of the first clamping plate 3.

[0025] There are two second clamping plates 10 movable between the two first clamping plates 3, and the two ends of the two second clamping plates 10 pass through two positioning through holes 11 respectively. The two positioning through holes 11 are respectively fixed on the two first clamping plates 3, and a bidirectional electric push rod 12 is fixedly connected between the ends of the two second clamping plates 10, and the width of the positioning through hole 11 is greater than the width of the second clamping plates 10.

[0026] During use, the two bidirectional electric push rods 12 are started so that the second clamping plate 10 can slide in the positioning hole 11, thereby changing the distance between the two second clamping plates 10, which can be suitable for the width clamping operation of the plate 2. At the same time, the two first clamping plates 3 can slide back and forth on the second clamping plates 10, and cooperate with the locking and positioning function of the electromagnet block 6 to change the distance between the two first clamping plates 3, which can be suitable for the length clamping operation of the plate 2.

[0027] At the same time, a grid plate 13 is provided between the two first clamping plates 3, a collecting box 14 is fixed at the bottom of the grid plate 13, the grid plate 13 is fixed on the workbench 1, a vacuum cleaner 15 is fixedly connected to the side end of the collecting box 14, the output end of the vacuum cleaner 15 is connected to the collecting box 14 through a vacuum pipe, a discharge pipe is fixed at the bottom of the collecting box 14, and a valve is fixed on the discharge pipe.

[0028] During use, the grid plate 13 is used and the vacuum cleaner 15 is started at the same time, so that the debris generated during the grinding operation can be adsorbed into the collection box 14, and after collection, the debris can be discharged through the discharge pipe by opening the valve.

[0029] Cover plates 16 are fixed to the bottom of the sides of the two first clamping plates 3 respectively, so that the cover plates 16 can change the first clamping plates 3 to slide over the exposed grid plates 13, ensuring that the debris in the collection box 14 will not fly out.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
