[0030] The working principle of the positioning component for preparing metal-based composite materials will be described in detail below.

[0031] like Figure 1-5As shown, when the metal-based composite material is prepared and positioned, first, according to the shape and size of the metal-based composite material, the control panel 11 is operated to start the drive motor 31, and the output shaft of the drive motor 31 drives the lead screw 32 to rotate, so that the threaded sleeve 33 on the lead screw 32 drives the slider 41 to slide along the inner wall of the slide groove 10 to limit the position, so that the connecting plate 6 on the right side slides along the movable groove 9, thereby adjusting the distance between the left and right clamping and fixing mechanisms 7, and then the two-way lead screw 71 is driven to rotate by rotating the left and right knobs 72, so that the moving block 73 on the two-way lead screw 71 drives the fixed plate 74 to slide along the limit position in the limit slide rail 61 through the limit block 76, thereby moving the upper and lower fixed plates 74 toward the upper and lower surfaces of the metal-based composite material, positioning and clamping the metal-based composite material, so that the anti-slip pad 75 is squeezed and fitted on the surface of the metal-based composite material, increasing the clamping of the fixed plate 74 In order to ensure the stability of the metal-based composite material, during the preparation of the metal-based composite material, the connecting rod 84 is pulled by the pull ring 85, so that the U-shaped card plate 87 is separated from the outer wall of the turntable handle 82, and then the turntable handle 82 is rotated to drive the left connecting disk 6 to rotate through the turn rod 81. During the rotation process, the metal-based composite material fixed on the clamping and fixing mechanism 7 is rotated through the rotating shaft 12 on the right connecting disk 6 to adjust the angle of the metal-based composite material. After the adjustment is completed, the force applied to the connecting rod 84 is released, and the elasticity of the reset spring 86 is used to reset the U-shaped card plate 87 so that the inner wall of the U-shaped card plate 87 is re-stuck on the outer wall side of the turntable handle 82, so that the rubber protrusion 88 on the U-shaped card plate 87 is pressed and fitted against the surface of the turntable handle 82, thereby increasing the friction between the U-shaped card plate 87 and the turntable handle 82, and preventing the turntable handle 82 from continuing to rotate, thereby completing the positioning of the rotation angle of the metal-based composite material.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
