[0022] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a pressing device with an anti-offset function includes a workbench 1. A wear-resistant plate 3 is fixedly connected to the workbench 1. The wear-resistant plate 3 is movably installed on the workbench 1 through a pressing assembly 4. The pressing assembly 4 includes a connection box 401, a mounting plate 402, a first movable groove 405, a first support block 406, a second support block 407, a clamping groove 408, a second movable plate 410, a first screw rod 413, a moving plate 422, a cylinder 423 and a pressing plate 424. The bottom of the connection box 401 is fixedly connected with the mounting plate 402. The first movable groove 405 is opened at the upper position of the connection box 401. The first support block 406 and the second support block 407 are movably installed in the first movable groove 405. The clamping groove 408 is opened on the first support block 406 and the second support block 407. The second movable plate 410 is movably installed below the second support block 407. The first screw rod 413 is movably installed with the second movable plate 410. The pressing assembly 4 further includes a mounting bolt 403. The mounting bolt 403 is movably installed on the mounting plate 402. The mounting plate 402 is movably installed on the workbench 1 through the mounting bolt 403. The bottom surface of the workbench 1 is fixedly connected with support feet 2. The pressing assembly 4 further includes a first anti-slip pad 404 and a first positioning plate 409. The first anti-slip pad 404 is fixedly connected to the connection box 401. The first anti-slip pad 404 is provided with a first movable groove 405, which corresponds to the first movable groove 405 on the connection box 401. The first positioning plate 409 is fixedly connected inside the connection box 401 and is located below the first support block 406. The second movable plate 410 is also located inside the connection box 401. The pressing assembly 4 further includes a movable rod 411 and a spring 412. The movable rod 411 is fixedly connected to the first positioning plate 409 or the second movable plate 410. The first support block 406 and the second support block 407 are movably installed with the movable rod 411. The spring 412 is located between the first positioning plate 409 and the first support block 406 or between the second movable plate 410 and the second support block 407. The pressing assembly 4 further includes a first rotating shaft 414, a first handle 415 and a first limiting block 416. The first screw rod 413 is movably installed on the connection box 401 through the first rotating shaft 414. The first handle 415 and the first limiting block 416 are fixedly connected to both ends of the first screw rod 413. The connection box 401 is movably installed on the workbench 1 through the mounting bolt 403, making the connection box 401 easy to install and disassemble. A number of screw holes are provided on the workbench 1, making the position of the connection box 401 easy to adjust. Operating the first screw rod 413 to rotate, the first screw rod 413 is connected to the second movable plate 410 through a screw hole. The inside of the connection box 401 is rectangular. The two sides of the second movable plate 410 are abutted against the two side walls inside the connection box 401. The bottom surface of the second movable plate 410 is attached to the bottom wall inside the connection box 401, making the second movable plate 410 only able to move linearly along the direction of the first screw rod 413. As the second movable plate 410 moves,The second support block 407 on the second movable plate 410 moves synchronously, thereby adjusting the distance between the first support block 406 and the second support block 407. After the second support block 407 is adjusted to the appropriate position, the wear-resistant plate 3 is clamped into the clamping grooves 408 of the first support block 406 and the second support block 407, so that the side of the wear-resistant plate 3 is caught by the clamping grooves 408. When the wear-resistant plate 3 moves downward, the first support block 406 and the second support block 407 move downward, thereby compressing the spring 412. After the spring 412 is compressed, it reversely pushes the first support block 406 and the second support block 407, so that the first support block 406 and the second support block 407 upwardly press and fix the bottom position of the wear-resistant plate 3. A first anti-slip pad 404 is provided on the connection box 401, and the bottom surface of the wear-resistant plate 3 presses the first anti-slip pad 404, thereby increasing the friction force so that the bottom surface of the wear-resistant plate 3 does not slide with the connection box 401.,

[0023] As Figure 1 、 Figure 2 and Figure 3 shown, a movable plate 422 is movably installed above the connection box 401. The air cylinder 423 is fixedly connected to the movable plate 422, and the output shaft of the air cylinder 423 is fixedly connected to the pressing plate 424. The pressing component 4 further includes a side plate 417, a second sliding rod 418, a second screw rod 419, a second bearing 420 and a second handle 421. The side plate 417 is fixedly connected to the connection box 401. The two ends of the second sliding rod 418 are respectively fixedly connected to the side plate 417. The rod body of the second screw rod 419 is movably installed on the side plate 417 through the second bearing 420. The second handle 421 is fixedly connected to one end of the second screw rod 419. The movable plate 422 is movably installed on the second sliding rod 418 and the second screw rod 419. The pressing component 4 further includes a second anti-slip pad 425. The second anti-slip pad 425 is fixedly connected to the pressing plate 424. When the second screw rod 419 is rotated, screw holes and sliding holes are provided on the movable plate 422 corresponding to the second screw rod 419 and the second sliding rod 418. When the second screw rod 419 rotates, the movable plate 422 is pushed, so that the movable plate 422 drives the air cylinder 423 below to move. After the air cylinder 423 moves to the appropriate position, the rotation of the second screw rod 419 is stopped, and then the air cylinder 423 is started, so that the pressing plate 424 and the second anti-slip pad 425 move downward. The pressing plate 424 presses the movable plate 422 downward, and the second anti-slip pad 425 increases the friction force between the pressing plate 424 and the wear-resistant plate 3. When the pressing plate 424 moves the wear-resistant plate 3 downward, the wear-resistant plate 3 is fixedly connected to the connection box 401. By the first anti-slip pad 404 and the second anti-slip pad 425, the friction force on both sides of the wear-resistant plate 3 is increased, so that the wear-resistant plate 3 is not easily displaced.,

[0024] It should be noted that the present utility model is a pressing device with an anti-offset function. Through corresponding screw holes provided on the workbench 1, the mounting bolts 403 on the mounting plate 402 can be fixedly connected to the screw holes on the workbench 1, thereby fixedly connecting the connection box 401. Rotate the first handle 415, so that the first handle 415 drives the first screw rod 413 to rotate, causing the first screw rod 413 to push the second movable plate 410 to move. As the second movable plate 410 moves, the second support block 407 on the second movable plate 410 synchronously moves in the first movable groove 405 of the connection box 401 and the first anti-slip pad 404, thereby adjusting the distance between the first support block 406 and the second support block 407 to facilitate adapting to plates of different sizes. When the second movable plate 410 is adjusted to the appropriate position, snap the wear-resistant plate 3 into the clamping grooves 408 of the first support block 406 and the second support block 407. Then rotate the second handle 421, so that the second handle 421 drives the second screw rod 419 to rotate, causing the second screw rod 419 to push the movable plate 422 to move, thereby moving the pressing plate 424 on the movable plate 422 to the appropriate position. Then start the air cylinder 423, so that the pressing plate 424 moves downward. The pressing plate 424 presses the wear-resistant plate 3 downward, causing the wear-resistant plate 3 to press the first support block 406, the second support block 407, the first support block 406, and the second support block 407 to move downward, move downward on the movable rod 411, and compress the spring 412. When the bottom surface of the wear-resistant plate 3 comes into contact with the first anti-slip pad 404, the air cylinder 423 continues to move downward a certain distance, causing the first anti-slip pad 404 and the second anti-slip pad 425 to be deformed by extrusion. The pressing plate 424 fixes and limits the wear-resistant plate 3 on the connection box 401. At this time, the wear-resistant plate 3 is squeezed and fixed in the vertical direction by the pressing plate 424, and the friction between the bottom surface and the upper surface is increased through the first anti-slip pad 404 and the second anti-slip pad 425. The side of the wear-resistant plate 3 is clamped and limited by the clamping groove 408. The downwardly compressed first support block 406 and second support block 407, under the reverse push of the spring 412, also generate a reverse fixing extrusion force on the wear-resistant plate 3, making the fixing effect of the wear-resistant plate 3 better and not prone to offset. When the processing is completed, after withdrawing the air cylinder 423, the spring 412 resumes its expansion and reversely pushes the wear-resistant plate 3 upward, separating the wear-resistant plate 3 from the first anti-slip pad 404, avoiding negative pressure adsorption due to excessive sealing between the wear-resistant plate 3 and the first anti-slip pad 404 after discharging the excess air, making the wear-resistant plate 3 easy to remove. Since the distance between the first support block 406 and the second support block 407 is easy to adjust, and the position of the pressing plate 424 is also easy to adjust, the pressing assembly 4 is convenient for adapting to wear-resistant plates 3 of different sizes and is more convenient to use.

It is only a preferred embodiment of the present utility model, and its description is relatively specific and detailed.
