[0018] 1. When the present invention is in use, a circular plate, a No. 1 connecting rod and a No. 2 connecting rod are provided, and a driving motor is used to drive the rotating rod to rotate, and the rotating rod drives the circular plate to rotate, and the circular plate drives the two No. 1 connecting rods at the bottom to deviate, and the two No. 1 connecting rods respectively drive the corresponding No. 2 connecting rods to move, and the No. 2 connecting rod pulls the corresponding No. 1 movable block to move, and the No. 1 movable block drives the two cross plates to move, and the two cross plates drive the corresponding side plates to move, and the side plates drive the corresponding No. 3 connecting rods to deviate, and the two adjacent No. 3 connecting rods are used to jointly push the connecting block to move, and at this time, the two connecting blocks move relatively, and drive the top No. 2 movable block to move, and the No. 2 movable block and the No. 1 movable block respectively drive the corresponding empty shell to move, and the empty shell drives the clamping pad thereon to move, and the relative movement of multiple clamping pads is used to achieve the clamping and fixation of the aluminum template to be processed, so as to avoid the displacement of the aluminum template to be processed during subsequent grinding and processing, which leads to the problem of processing misalignment.

[0019] 2. When the present invention is in use, the vacuum cleaner, the duct and the dust suction pipe are provided.

[0043] Working principle: When the present invention is in use, the motor 20 is first driven, so that the motor 20 drives the rotating rod 21 to rotate, and the rotating rod 21 drives the circular plate 26 to rotate while also driving the gear 19 on the rotating rod 21 to rotate, and the gear 19 drives the two outer racks 18 to move relative to each other, and the two racks 18 respectively drive the corresponding connecting plates 17 to move, and the connecting plates 17 drive the corresponding storage boxes 12 to move, and the storage boxes 12 drive the movable baffles 7 to move. At this time, the two movable baffles 7 are relatively separated, so that the top of the grinding box 1 is open, which is convenient for the staff to put the aluminum template 25 to be processed into the grinding box 1 for subsequent processing, and the above process also occurs that the circular plate 26 drives the two No. 1 connecting rods 27 at the bottom to deviate, and the two No. 1 connecting rods 27 respectively drive the corresponding No. 2 connecting rods 28 to move, and the No. 2 connecting rods 2 8 pulls the corresponding No. 1 movable block 29 to move, the No. 1 movable block 29 drives the two horizontal plates 30 to move, the two horizontal plates 30 drive the corresponding side plates 31 to move, the side plates 31 drive the corresponding No. 3 connecting rods 32 to deflect, and the two adjacent No. 3 connecting rods 32 are used to jointly push the connecting block 33 to move. At this time, the two connecting blocks 33 move relatively, and drive the top No. 2 movable block 34 to move, the No. 2 movable block 34 and the No. 1 movable block 29 respectively drive the corresponding empty shell 35 to move, and the empty shell 35 drives the clamping pad 36 thereon to move, and the relative movement of multiple clamping pads 36 is used to increase the space for placing the aluminum template 25 to be processed. After the aluminum template 25 to be processed is placed, it is placed on the top of the pad 5, and the motor 20 is driven to reverse, so as to realize the reset of the two movable baffles 7 and the multiple clamping pads 36. The top of the grinding box 1 is sealed by resetting the two movable baffles 7 to prevent aluminum powder and waste gas generated during subsequent grinding from entering the working environment, causing environmental pollution, and even causing respiratory infections and diseases to the staff. The relative proximity of the multiple clamping pads 36 realizes the clamping and positioning of the aluminum template 25 to be processed, to prevent the displacement of the aluminum template 25 to be processed during subsequent grinding, resulting in processing misalignment. In the process where the two movable baffles 7 are relatively far away from each other, resulting in the top of the grinding box 1 being opened, the two movable baffles 7 also use the slider 39 and the slide groove 38 to push the two bottom columns 40 to move, and the two columns 40 drive the bottom guide block 42 to slide in the corresponding guide groove 4. Since the guide groove 4 is inclined, the two columns 40 are relatively far away from each other. The column 40 drives the two outer grinders 43 to move together. When the two movable baffles 7 move relatively close to each other, the multiple grinders 43 slowly move close to the movable baffle 7. After the two adjacent grinders 43 move to fit the side of the edge of the aluminum template 25 to be processed, the movable baffle 7 continues to move. The two grinders 43 drive the corresponding mounting rings 44 to twist on the outside of the column 40. The two mounting rings 44 jointly compress the torsion spring 41, and the torsion spring 41 is used to apply pressure to the grinding rollers on the two grinders 43 to improve the fit between the grinding rollers and the side of the edge of the aluminum template 25 to be processed, thereby improving the subsequent grinding effect. At this time, multiple grinders 43 are driven to grind the edge of the aluminum template 25 to be processed, and during the grinding process,Drive two vacuum cleaners 10, so that the two vacuum cleaners 10 use the front and rear two vacuum pipes 11 to absorb the aluminum dust and exhaust gas generated by grinding inside the grinding box 1, and then enter the corresponding storage box 12 along the two guide tubes 14. The gas is discharged along the filter cotton net 13, and the exhaust gas is filtered by the filter cotton net 13. At the same time, the aluminum dust remains in the storage box 12, effectively preventing the aluminum dust and exhaust gas from flying in the working environment and causing harm to the staff. After the processing is completed, repeat the above installation steps to remove it, which is convenient to operate.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
