[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] refer to Figures 1-4The automatic clamping fixture for multi-length interchangeable plates shown includes a rotary motor 1 and a base plate 2. The rotating shaft of the rotary motor 1 is fixedly connected to the base plate 2. A clamping cylinder 3 is fixedly connected to the base plate 2. The piston rod of the clamping cylinder 3 passes through the base plate 2 and is fixedly connected to a carrier 4. The carrier 4 is provided with multiple positioning slots 401. Side positioning blocks 5 and limiting plates 6 are fixedly connected to both sides of the carrier 4 next to each positioning slot 401. An elastic plunger 501 is fixedly connected to the side positioning blocks 5. A baffle 7 is fixedly connected to the middle of the base plate 2. The baffle 7 can clamp the interchangeable plates when the piston rod of the clamping cylinder 3 extends. The carrier 4 is located between the base plate 2 and the baffle 7. A linear module 8 is fixedly connected to the lower end of the carrier 4. A positioning base plate 801 is fixedly connected to the moving platform of the linear module 8. The linear module 8 is used to adjust the height of the positioning base plate 801.

[0020] Multiple positioning slots 401 are arranged in a linear array on the carrier 4. The positioning slots 401 are used to position and place the square tube. The elastic plunger 501 is fixedly connected to the side wall of the side positioning block 5. The elastic plunger 501 can pre-tighten the square tube after it is placed.

[0021] A gap is left between the limiting plate 6 and the carrier 4, and the limiting plate 6 can be offset from the baffle 7.

[0022] The lower end of the carrier 4 is fixedly connected to a guide post 402, and the positioning base plate 801 is slidably connected to the guide post 402. The guide post 402 can guide the position adjustment of the positioning base plate 801.

[0023] The positioning base plate 801 is U-shaped, and its two ends are slidably connected to the guide post 402. The positioning base plate 801 has an arc-shaped surface, which facilitates the placement of interchangeable plates.

[0024] The carrier 4 is provided with positioning holes, and a positioning post is fixedly connected to the base plate 2. The positioning post is set in correspondence with the positioning hole, and the positioning post is used to match the positioning hole for positioning and installing the carrier 4.

[0025] The working principle of this utility model is as follows: When using this utility model, the height of the positioning base plate 801 is adjusted according to the length of the interchangeable plate to be clamped. The height of the positioning base plate 801 can be adjusted by driving the linear module 8 to lift and lower. When clamping, the bottom of the interchangeable plate is placed down along the positioning groove 401 and the limiting plate 6 so that the groove of the interchangeable plate matches the positioning base plate 801. Then, the piston rod of the clamping cylinder 3 extends, and the carrier 4 moves closer to the baffle 7 to clamp the interchangeable plate onto the baffle 7.
