However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0018] A cutting device for PVC material multi-size test samples, as Figure 1 and Figure 2 shown, includes a workbench 1, a first motor 2, a unidirectional lead screw 3, a clamping assembly, a limiting assembly and a cutting assembly. The first motor 2 is connected to the right side of the workbench 1, the unidirectional lead screw 3 is rotatably connected inside the workbench 1, and the unidirectional lead screw 3 is connected to the output shaft of the first motor 2. A clamping assembly is provided on the workbench 1, a limiting assembly is also provided on the workbench 1, and a cutting assembly is provided on the workbench 1.

[0019] As Figures 1 - 3 shown, the clamping assembly includes a sliding frame 4, a turntable 6, a clamping frame 7, a gear set 8 and a second motor 9. The sliding frame 4 is threadedly connected to the lead screw. The sliding frame 4 is slidably connected to the workbench 1. Six sliding grooves 5 are formed on the sliding frame 4. The turntable 6 is rotatably connected to the left side of the sliding frame 4. Six clamping frames 7 are slidably connected to the sliding frame 4 through the sliding grooves 5. The clamping frames 7 are all in contact and cooperation with the turntable 6. Six guiding grooves are formed on the turntable 6 to facilitate contact and cooperation with the clamping frames 7. The second motor 9 is connected to the front part of the sliding frame 4, and a gear set 8 is connected between the output shaft of the second motor 9 and the turntable 6.

[0020] As Figure 1 and Figure 2 shown, the limiting assembly includes a support frame 10, a bidirectional lead screw 11, sliders 12 and runners 13. The support frame 10 is connected to the upper side of the middle part of the workbench 1. The bidirectional lead screw 11 is rotatably connected to the front part of the support frame 10. A handle is provided on the bidirectional lead screw 11 for easy rotation.

[0022] When using the present utility model, first place the workbench 1 in the cutting area of the PVC material test sample. Then start the second motor 9. Through the meshing movement of the gear set 8, the turntable 6 rotates.

After the other end of the PVC pipe moves to the specified cutting length on the rotating wheels 13, start the cutting knife 15 on the robotic arm 14 to cut the PVC pipe. Thus, by starting the second motor 9, the cutting size of the PVC pipe can be adjusted flexibly and accurately, which can facilitate the clamping of PVC pipes of different sizes, flexibly adjust the cutting size of the PVC pipe, reduce the labor intensity, and improve the test accuracy.
