For large-format sheet metals, only CNC machine tools that match them can be purchased again, which not only increases the overall production cost, but also makes the idle CNC machine tools easy to be damaged, resulting in a waste of resources.
[0005] To achieve the above-mentioned purpose, a high-precision sheet metal positioning device for an ultra-large-format CNC machine tool is provided, comprising a workbench and a conveyor table fixedly connected to the bottom of the workbench surface, connecting plates are fixedly connected on both sides of the workbench, limit plates are slidably connected on both sides of the top of the workbench surface, and an adjustment component suitable for large-format sheet metal processing is arranged between the limit plate and the connecting plate, a mounting frame is fixedly connected to the top of the connecting plate, a first electric push rod is installed on the top of the inner side of the mounting frame, a fixed plate is fixedly connected to the bottom end of the first electric push rod, a processing instrument for sheet metal processing is fixedly connected below the fixed plate, and a distance sensor for positioning is also fixedly connected below the fixed plate.
[0006] As a further improvement of the present technical solution, the adjustment assembly includes a fixed cylinder fixedly connected to the inner side of the connecting block, a compression spring fixedly connected to the bottom end of the fixed cylinder, a movable column fixedly connected to one side of the compression spring for driving the limit plate to move, and the movable column slides inside the fixed cylinder.

[0008] As a further improvement of the technical solution, return springs are fixedly connected to the four sides of the bottom end of the fixing plate, and a resistance plate for fixing the sheet metal is fixedly connected to the bottom end of the return spring.

[0011] As a further improvement of the present technical solution, the inclination angle of the inclined plate is between 30 degrees and 60 degrees.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. The high-precision sheet metal positioning device for ultra-large-format CNC machine tools is provided with an adjustment component so that when the limit plate moves to the processing area with sheet metals of different widths, it adaptively drives the moving column to squeeze the compression spring and slide inside the fixed cylinder. At this time, the distance sensor will move with the distance of the sheet metal, and divide the processing area matching the processing instrument according to the needs, and then start the first electric push rod to move downward, and drive the contact plate to position and fix the sheet metal first, and then start the processing instrument to perform stamping, cutting, welding and other operations on the sheet metal. Because the large-format sheet metal operation area is wide, the reciprocating screw rod is driven to rotate by the servo motor, so that the moving block can drive the processing instrument to move left and right, thereby realizing the processing of large-format sheet metals of different sizes.
[0014] 2. The high-precision sheet metal positioning device for ultra-large-format CNC machine tools extends the limit plate to the feed table surface and fixes a ramp plate thereto. The ramp plate inclination angle is determined by the width of the sheet metal accommodated by the overall device. The normal ramp plate inclination angle is between 30 and 60 degrees. The larger the ramp plate angle, the larger the accommodated sheet metal width. At this time, multiple sheet metals are arranged in sequence and placed on the feed table surface. The second electric push rod pushes the last sheet metal forward, allowing the first sheet metal to enter the processing area, which reduces the labor intensity of the staff to a certain extent.

A groove 12 is provided at the top of the inner side of the mounting frame 5, and a reciprocating screw rod 13 is rotatably connected inside the groove 12. A servo motor 14 coaxially connected to the reciprocating screw rod 13 is fixed to the outer side of the mounting frame 5, and a nut pair on the outer side of the reciprocating screw rod 13 is connected to a fixed block 15 for driving the processing instrument to move left and right. The top of the first electric push rod 6 is fixed to the bottom end of the fixed block 15, and reset springs 16 are fixed to the four sides of the bottom end of the fixed plate 7. The bottom end of the reset spring 16 is fixed to a contact plate 17 for fixing the sheet metal. A second electric push rod 19 is fixed to one side of the top of the feeding table 18. One side of the electric push rod 19 is fixedly connected with a push plate 20 for pushing the sheet metal to move. One side of the limit plate 4 extends to the surface of the feed table 18 and is fixedly connected with an inclined plate 21. The inclination angle of the inclined plate 21 is between 30 degrees and 60 degrees. In the existing sheet metal CNC processing machine tools, only sheet metals that are equal to or smaller than the size of the CNC machine tool can be positioned and processed.

Before work, multiple sheet metals are arranged in sequence and placed on the surface of the feed table 18. At this time, the second electric push rod 19 is turned on to push the sheet metal to move forward. At this time, the sheet metal first contacts the inclined plate 21 and slides between the two limit plates 4. Because the width of the sheet metal is greater than one The distance between the limit plates 4 is adjusted so that the sheet metal slides in and drives the moving column 11 on one side of the limit plate 4 to squeeze the compression spring 10, and slide inside the fixed cylinder 9, so that it increases the distance between the pair of limit plates 4.

After moving down a certain distance, the contact plates 17 on the four sides of the bottom end of the fixed plate 7 first position and fix the sheet metal, and then start the processing instrument to perform stamping, cutting, welding and other operations on the sheet metal.Because the large-format sheet metal operation area is wide, the servo motor 14 drives the reciprocating screw 13 to rotate, so that the moving block can drive the processing instrument to move left and right, realizing the processing of large-format sheet metals of different sizes. Finally, the processed sheet metal is transported to the next working area along the conveyor table 2.
[0024] Working principle: Before work, multiple sheet metals are arranged in sequence and placed on the surface of the feeding table 18. At this time, the second electric push rod 19 is turned on to push the sheet metal forward. At this time, the sheet metal first contacts the inclined plate 21 and slides between the two limit plates 4. Because the width of the sheet metal is greater than the distance between a pair of limit plates 4, the sheet metal slides in and drives the moving column 11 on one side of the limit plate 4 to squeeze the compression spring 10, and slides inside the fixed cylinder 9, so that it increases the distance between the pair of limit plates 4. At the same time, the pair of limit plates 4 also pressurizes and fixes the two sides of the sheet metal. Then the sheet metal is pushed by the second electric push rod 19, so that the first sheet metal enters the processing area In the domain, at this time, the distance sensor 8 will move with the distance of the sheet metal moving, and divide the processing area matching the processing instrument according to the needs, and then start the first electric push rod 6 to move downward. After moving down a certain distance, the contact plates 17 located on the four sides of the bottom of the fixed plate 7 first position and fix the sheet metal, and then start the processing instrument to perform stamping, cutting, welding and other operations on the sheet metal. Because the large-format sheet metal operation area is wide, the servo motor 14 drives the reciprocating screw rod 13 to rotate, so that the moving block can drive the processing instrument to move left and right, realizing the processing of large-format sheet metals of different sizes. Finally, the processed sheet metal is transported to the next working area along the conveyor table 2.
