[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 andFigure 4 This utility model provides a technical solution: a pressing machine with a quick-change pressing table, comprising a pressing machine body 1, a hydraulic cylinder 2, and a pressing plate 3.

[0023] The top of the pressing machine body 1 is equipped with a hydraulic cylinder 2 and a drive motor 306. The bottom of the hydraulic cylinder 2 is connected to a pressure plate 3. The inside of the pressing machine body 1 is equipped with a turntable 301. A pressing table body 302 is provided on the upper side of the turntable 301. Transmission gear blocks 303 are equidistantly connected to the outer side of the turntable 301. The outer side of the transmission gear blocks 303 meshes with a drive gear 304. A rotating shaft 305 is installed in the middle of the drive gear 304. The inside of the turntable 301 is provided with a docking groove 401, a guide groove 404 and a rotating groove 408. The bottom of the pressing table body 302 is connected to a docking block 4.

[0024] The docking block 4 has a positioning groove 402 inside. Positioning pins 403 are inserted into the positioning groove 402 and the guide groove 404. An installation pin 406 is rotatably mounted inside the turntable 301 through a bearing seat. An adjusting arm 405 is provided between the installation pin 406 and the positioning pin 403. The two ends of the adjusting arm 405 are hinged to the positioning pin 403 and the installation pin 406 respectively through a connecting block and a pin. A rotating rod 407 is installed on the outside of the installation pin 406. The rotating rod 407 is inserted through the rotating groove 408. Limiting screw holes are provided inside the turntable 301 and on one side of the rotating rod 407. The turntable 301 is threadedly connected to the limiting screw 409 through the limiting screw holes.

[0025] In practice, to facilitate the replacement of the pressing table body 302, the limiting screw 409 is removed by the thread action of the limiting screw hole and the limiting screw 409. The rotating rod 407 is rotated along the rotating groove 408 until the rotating rod 407 is rotated from one end of the rotating groove 408 to the other end. At this time, the mounting column 406 installed with the rotating rod 407 will drive the adjusting arm 405 to rotate, thereby driving the positioning column 403 to disengage from the positioning groove 402 at the bottom of the docking block 4. At this time, the operator can move the pressing table body 302 vertically upward until the docking block 4 at the bottom of the pressing table body 302 disengages from the docking groove 401 opened inside the turntable 301.

[0026] Align the mating block 4 at the bottom of the replacement pressing table body 302 with the mating groove 401 and insert it. Push the rotating rod 407 again to push the rotating rod 407 back to its original position, and use the limiting screw 409 to limit the connection to complete the replacement of the pressing table body 302. This pressing machine that can quickly replace the pressing table only requires a single limiting screw 409 and the rotation of the rotating rod 407 to complete the operation of replacing the pressing table body 302. It is convenient to use and has high replacement efficiency.

[0027] See Figure 4 andFigure 5 It is known that the top of the turntable 301 is welded with connecting columns 5 at equal intervals, the connecting columns 5 are provided with mounting grooves 501, the mounting grooves 501 are installed with reset springs 502, the top of the reset springs 502 is connected to the plug-in column 503, and the inner side of the plug-in column 503 is connected with a limiting layer 504.

[0028] In practical implementation, to prevent items from shifting when placed on the upper side of the pressing table body 302, which would hinder the pressing operation, a connecting column 5 and a plug-in column 503 are provided on the outer side of the pressing table body 302. When the operator places the product to be pressed, the plug-in column 503 and the upper limiting layer 504 are pushed upward by the return spring 502 inside the mounting groove 501, forming a limiting ring. At this time, the product will be completely located on the upper side of the pressing table body 302. During pressing, the hydraulic cylinder 2 drives the pressure plate 3 to move downward, and at the same time pushes the plug-in column 503 and the limiting layer 504 to move downward along the mounting groove 501 to complete the pressing. After pressing, the plug-in column 503 and the limiting layer 504 are reset under the action of the return spring 502. This pressing machine with quick pressing table replacement is equipped with a plug-in column 503 and a limiting layer 504 for limiting the product, which helps to improve the accuracy of product pressing.

[0029] In summary, when using this press machine with a quick-change pressing table, the product is placed on the upper side of the pressing table body 302. The drive motor 306 drives the drive gear 304 to rotate via the rotating shaft 305. When the drive gear 304 rotates, it meshes with the transmission gear block 303, driving the turntable 301 and the pressing table body 302 to rotate. The pressing table body 302, on which the product to be pressed is placed, is moved to the bottom of the hydraulic cylinder 2. The hydraulic cylinder 2 drives the pressure plate 3 to move downward, and at the same time pushes the insertion post 503 and the limiting layer 504 to move downward along the mounting groove 501 to complete the pressing.
