[0027] The present invention provides a flatness detection jig for a large printer suction paperboard, such as Figure 1 and Figure 2 As shown, it includes a base plate 1, on which a bracket 11 is mounted; a movable plate 2, which is slidably connected to the bracket 11, and a first lifting mechanism 3 is provided between the movable plate 2 and the bracket 11 to drive the movable plate 2 to rise and fall relative to the base plate 1, and a plurality of pressing blocks 4 are connected below the movable plate 2; a plurality of dial indicators 5, which are installed on the bracket 11 with the aid of a slide 6, and a second lifting mechanism 7 is provided between the slide 6 and the bracket 11 to drive the slide 6 to rise and fall relative to the base plate 1; and the plurality of dial indicators 5 are arranged in a direction parallel to the length direction of the base plate 1.
[0028] Based on the above structure, when it is necessary to detect the flatness of the suction board of the large printer, the suction board of the large printer is placed on the bottom plate 1, the movable plate 2 is driven to move downward, the pressure block 4 presses the suction board of the large printer, the slide 6 is driven to move downward, and multiple dial indicators 5 move downward at the same time and move to the detection position, so that multiple detection positions can be detected at the same time, with high work efficiency and high detection accuracy.
[0029] In this embodiment, the movable plate 2 is fixedly connected to a plurality of connecting rods 21 extending downward, the ends of the connecting rods 21 are connected to the top ends of the springs 22, and the bottom ends of the springs 22 are connected to the pressing blocks 4. The pressing blocks 4 are suspended by the springs 22, so that the pressing blocks 4 will not cause a hard impact on the large printer suction paperboard, thereby avoiding scratching or damaging the large printer suction paperboard.
[0030] In this embodiment, the first lifting mechanism 3 includes a first telescopic cylinder, the cylinder body of the first telescopic cylinder is fixed to the bracket 11, and the telescopic rod of the first telescopic cylinder is connected to the movable plate 2; the movable plate 2 is connected to a guide rod 31, the bracket 11 is provided with a guide hole 32, and the guide rod 31 is slidably connected to the guide hole 32. The movement of the movable plate 2 and the guidance of the movement are achieved through the above structure.
