[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] like Figures 1 to 4As shown, the plate pressing device comprises a frame 1, a positioning base 2, a drive cylinder 31, a drive connecting rod, a rotating base 39, a pressing rod 35, and a copper pressing head 36. The frame 1 comprises a base plate 11, a vertical plate 14, and a top plate 12. The base plate 11 is provided with a plurality of connecting holes at both ends. The vertical plates 14 are symmetrically fixed to the ends of the base plate 11, and the top plate 12 is fixed to the top of the vertical plate 14. A pressing hole 15 is provided in the center of the top plate 12, and two fixing slots 13 are symmetrically provided on the top of the top plate 12. The positioning base 2 is screwed into the positioning slot 21, which facilitates the replacement of different positioning bases 2 as needed. The positioning base 2 is provided with a positioning slot 21 for positioning the plate 4. The positioning slot 21 facilitates the positioning of the plate 4. The drive cylinder 31 can be any of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. In this embodiment, a hydraulic cylinder is used. The bottom of the drive cylinder 31 is fixed to the base plate 11 by screws and inserted into the pressing hole 15 of the top plate 12. The piston rod of the drive cylinder 31 is connected to the drive base 32. The rotating seat 39 is fixed to the top plate 12 and is symmetrically located on both sides of the pressing hole 15. The pressing rod 35 is L-shaped, and the corners of the pressing rod 35 are rotatably mounted on the rotating seat 39 via an axis. The end of the pressing rod 35 opposite the positioning seat 2 is provided with a connecting groove 351, and a copper pressure head 36 is installed in the connecting groove 351. The copper pressure head 36 is installed in the connecting groove 351 by screws, which makes it easy to replace the copper pressure head 36. The copper pressure head 36 is not easy to damage the plate 4 and protects the surface of the plate 4. The driving connecting rod includes a first connecting rod 33 and a second connecting rod 34. The two ends of the first connecting rod 33 are respectively provided with a first upper rotating groove 331 and a first lower rotating groove 332. The two ends of the second connecting rod 34 are respectively provided with a second upper rotating groove 341 and a second lower rotating groove 342. The pressing rod 35 is symmetrically provided with two, and the other end of the pressing rod 35 is movably inserted into the first upper rotating groove 331 and the second upper rotating groove 341, and is rotatably connected to the first driving connecting rod and the second driving connecting rod via an axis. The first lower rotation groove 332 is movably inserted into the end of the second connecting rod 34. The second lower rotation groove 342 of the second connecting rod 34 is movably inserted into the drive base 32. The first connecting rod 33, the second connecting rod 34, and the drive base 32 are rotatably connected via an axis. The drive base 32, the driving connecting rod, and the clamping rod 35 form a linkage mechanism. This not only makes the structure more compact, does not affect the placement and welding of the workpiece, and is less likely to cause interference, but also increases the opening and closing angle of the clamping rod 35, making it easier to install and remove the sheet 4 and increasing the thickness range of the clamped sheet 4. The driving cylinder 31 drives the clamping rod 35 to rotate via the driving connecting rod, thereby loosening and clamping the sheet 4.

[0021] During operation, the plate 4 is placed into the positioning groove 21, and then the drive cylinder 31 is activated. The drive cylinder 31 drives the drive base 32 upward, which drives the copper ram 36 at the end of the clamping rod 35 downward via the drive connecting rod. The copper ram 36 presses against the plate 4, positioning and fixing the plate 4. Other parts can then be installed for welding. When welding is complete, the drive cylinder 31 is activated, the piston rod of the drive cylinder 31 retracts, the drive base 32 descends, and the drive base 32 drives the copper ram 36 at the end of the clamping rod 35 upward via the drive connecting rod, causing the copper ram 36 to move away from the plate 4. The welded workpiece can then be removed.

[0022] The overall structure is compact and not restricted by external space. The plate 4 can also be pressed internally. The driving cylinder 31 is used for pressing, which can ensure reliable pressing force and facilitate disassembly and assembly, thereby improving production efficiency.
