[0025] See also Figure 5 As shown, a rubber pad 20 is fixed on the inner side of the movable platform 9; when working, when the edge of the sheet metal is easily deformed by force, the movable platform 9 is separated from it by the structure of the rubber pad 20, so as to prevent the movable platform 9 from colliding with the edge of the sheet metal during movement, thereby preventing the processing quality of the sheet metal from being reduced.

[0026] Working principle, sheet metal is the cold processing technology for metal plates, which includes folding, punching, shearing, welding and riveting and other processing technologies. The products produced by processing metal plates through sheet metal technology are called sheet metal parts, which are widely used in daily life. The existing fixing device drives the extrusion plate to move through the threaded shaft, so that it is fixed by squeezing and clamping around the sheet metal part. The contact area of ​​the extrusion position is small. If the extrusion force is large, the sheet metal part will be deformed, and its processing quality will be reduced. In order to solve this problem, a fixing mechanism and a limiting mechanism are set to place the sheet metal part on the surface of the support plate 3, and it is rotated to the appropriate direction as required, so that its bottom side surface is closely fitted with the suction cup 4, and then the vacuum pump 6 is controlled to extract the air in the inner cavity 31 of the support plate 3 through the conduit 7. At this time, the suction cup 4 will absorb and fix the sheet metal part on the top side of the support plate 3, so that while fixing the sheet metal part, it will not be deformed by force, and the handle 18 is turned to drive the screw rod 17 to rotate, thereby pushing The connecting seat 81 slides inside the slide groove 8, thereby moving the moving platform 9 toward the sheet metal part. When it contacts the sheet metal part, the handle 18 is stopped. At this time, the cylinder 16 is controlled to retract its inner piston rod, thereby pulling the telescopic plate 10 to retract to the inside of the moving platform 9. When the clamping plate 12 contacts the top surface of the sheet metal part, the telescopic plate 10 continues to descend. At this time, the clamping plate 12 causes the spring 13 to compress. When the bottom card slot 14 of the slide rod 11 moves to the top side of the telescopic plate 10, the elastic card block 15 is buckled inside the card slot 14, and the control The air cylinder 16 stops contracting, and the clamping plate 12 is now clamped on the top side of the sheet metal with a constant clamping force. Thus, with the cooperation of the support plate 3, the sheet metal is provided with an auxiliary fixing function so that its position will not shift during the processing. After the processing is completed, the air cylinder 16 is controlled to drive the clamping plate 12 away from the surface of the sheet metal. The vacuum pump 6 is then controlled to fill the inside of the cavity 31 with air to release the fixation of the sheet metal. The sheet metal is then removed to complete the processing, thus solving the problem of deformation caused by stress when the sheet metal is clamped and fixed.
