[0020] In order to enable those skilled in the art of the present technology to better understand the solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in conjunction with the embodiments. Embodiment

[0022] Refer to Figures 1-4 , this embodiment provides a thin-walled part plate-changing fixture, including a base plate 1. A clamping mechanism 2 is arranged above the base plate 1. The clamping mechanism 2 includes a pushing component 3, a driving component 4, an adjusting component 5 and a clamping component 6. The number of the clamping mechanisms 2 is two groups, and the two groups of clamping mechanisms 2 are symmetrically arranged left and right. A tooling plate 7 is arranged between the two groups of clamping mechanisms 2. Specifically, it is a tooling for thin-walled part production, which is prior art. The tooling plate 7 is movably attached to the upper part of the base plate 1, and the tooling plate 7 is movably attached to the lower part of the pressing block 604. The number of the clamping components 6 in each group of clamping mechanisms 2 is three. The pushing component 3 includes a slide rail 301, and the slide rail 301 is fixedly connected to the upper part of the base plate 1. A slide bar 302 is slidably connected above the slide rail 301. The slide bar 302 can only slide on the slide rail 301 and will not fall off the slide rail 301. The pushing component 3 further includes a top block 303, and the top block 303 is fixedly connected to the upper part of the slide bar 302. An inclined surface is arranged on the top block 303, and the inclined surface faces backward. The number of the top blocks 303 is six, and one top block 303 is arranged below the pressure plate 601 in each group of clamping components 6. The adjusting component 5 includes a pushing block 501, and the pushing block 501 is fixedly connected to the left side of the slide bar 302. A screw 502 penetrates through the back surface of the pushing block 501 in a threaded manner. The driving component 4 includes a top piece 401, and the top piece 401 is rotatably connected to the front end of the screw 502. A hydraulic push rod 402 is fixedly connected in front of the top piece 401. The driving component 4 further includes a support piece 403, and the support piece 403 is fixedly connected to the front end of the hydraulic push rod 402. The support piece 403 is fixedly connected to the upper part of the base plate 1.

[0023] When the above-mentioned device is in specific use, first place the tooling plate 7 above the bottom plate 1 and make it located below the pressing block 604. At this time, start the hydraulic push rod 402 to make it extend. The hydraulic push rod 402 will push the top piece 401, and then drive the screw rod 502 and the pushing block 501, so that the sliding bar 302 slides backward on the slide rail 301. By the sliding bar 302 sliding backward on the slide rail 301, it will drive the top block 303 to move backward. By the top block 303 moving backward, it will push against the pressing plate 601. The pressing plate 601 will tilt under the support of the rotating column 602 and the support plate 603, and the other end thereof will drive the pressing block 604 to press down, so as to press the tooling plate 7 tightly above the bottom plate 1. At this time, rotate the screw rod 502 to drive the pushing block 501, so that the sliding bar 302 slides slightly on the slide rail 301 to adjust the force of the top block 303 pushing against the pressing plate 601, achieving the effect of facilitating the adjustment of the clamping force. Embodiment

[0024] See Figures 1-4 , on the basis of Embodiment 1, the clamping assembly 6 includes a pressing plate 601. The front surface of the pressing plate 601 penetrates and is fixedly connected with a rotating column 602. The outer surface of the rotating column 602 is rotatably connected with a support plate 603. Two support plates 603 are arranged on each rotating column 602. The rotating column 602 and the support plate 603 are rotatably connected through a bearing. The support plate 603 is fixedly connected above the bottom plate 1. A pressing block 604 is fixedly connected below the pressing plate 601. The clamping assembly 6 further includes a counterweight ball 605. The counterweight ball 605 is fixedly connected above the pressing plate 601. The counterweight ball 605 is arranged on the side of the pressing plate 601 away from the tooling plate 7. The counterweight ball 605 can press down the pressing plate 601 under the action of gravity.

[0025] When the above-mentioned device is in specific use, when the top block 303 pushes against the pressing plate 601, one end of the pressing plate 601 in contact with the top block 303 will lift. At this time, the rotating column 602 will rotate in the support plate 603, and the other end of the pressing plate 601 will descend and drive the pressing block 604 to press the tooling plate 7 tightly. When it is necessary to loosen the tooling plate 7, start the hydraulic push rod 402 to make it contract, so that the top block 303 moves away from the pressing plate 601. At this time, after the pressing plate 601 loses the support of the top block 303, the counterweight ball 605 will press down the pressing plate 601 under the action of gravity, making the pressing block 604 at the other end thereof lift, so as to loosen the tooling plate 7 for facilitating the replacement of the tooling plate 7.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
