[0040] A calibration seat 3, which is used to simulate a plate roller seat 4 and can be detachably mounted on a plate roller seat mounting frame 5;

[0041] An adjusting portion 6, used for adjusting the position of the calibration seat 3 on the frame 2;

[0042] The calibration seat 3 includes a first calibration seat 31 and a second calibration seat 32;

[0043] The calibration seat 3 is provided with alignment holes 30, and the alignment holes 30 include a first alignment hole 301 provided on the first calibration seat 31 and a second alignment hole 302 provided on the second calibration seat 32;

[0044] When in use, one end of the calibration shaft 1 passes through the first alignment hole 301 and the other end passes through the second alignment hole 302, so that the first alignment hole 301 and the second alignment hole 302 remain coaxial and concentric, and the calibration shaft 1 constrains the concentricity of the first calibration seat 31 and the second calibration seat 32; then adjust the adjustment part 6 to adjust the position of the calibration seat 3 on the frame 2.

[0045] In the prior art, the holes on the plate roller seat for mounting and fixing the two ends of the plate roller are blind holes, and the cylindricity accuracy of the plate roller is low; in order to adjust the concentricity of the plate roller seats on the left and right sides, it is necessary to continuously adjust and calibrate the positions of the two plate roller seats and the three plate rollers. However, in the utility model, since the calibration axis constrains the concentricity of the first calibration seat 31 and the second calibration seat 32, after calibrating the position of the calibration seat, the plate roller seat is replaced with the calibration seat, so that the concentricity between the plate roller seat and the calibration seat can be consistent, thereby helping to improve the assembly accuracy of the plate roller seat.

[0046] The calibration shaft 1 has high-precision cylindricity to improve the concentricity of the first calibration seat 31 and the second calibration seat 32 when the calibration shaft 1 passes through the first alignment hole 301 and the second alignment hole 302 .

[0047] Specifically, the alignment hole 30 is precisely matched and installed with the calibration shaft 1 .

[0049] like Figure 2 As shown, further, the adjustment portion 6 includes a first adjustment group 61 and a second adjustment group 62; the first adjustment group 61 is used to adjust the vertical distance of the calibration seat 3 relative to the mounting hole 21 (the vertical distance refers to the vertical distance). Figure 2 The distance in the Z axis direction);

[0050] The second adjustment group 62 is used to adjust the left and right distance of the calibration seat 3 relative to the mounting hole 21 in the vertical direction (the left and right distance in the vertical direction refers to Figure 2 The distance along the Y axis).

[0051] The position of the calibration shaft 1 in the mounting hole 21 is adjusted by adjusting the first adjustment group 61 and the second adjustment group 62 until the central axes of the first alignment hole 301 , the second alignment hole 302 and the mounting hole coincide with each other.

[0052] Specifically, the first adjustment group 61 and the second adjustment group 62 can be any components with an adjustment function, such as adjustment screws.

[0053] like Figure 2 As shown, specifically, the first adjustment group 61 includes a first push block 611 and a first push block adjustment member 612 arranged on the plate roller seat mounting frame 5, and the first push block adjustment member 612 can push the first push block 611 to move to adjust the upper and lower positions of the plate roller seat mounting frame 5 in the vertical direction of the frame 2.

[0054] Specifically, the second adjustment group 62 includes a second push block 621 and a second push block adjustment member 622 provided on the plate roller seat mounting frame 5, and the second push block adjustment member 622 can push the second push block 621 to move to adjust the left and right position of the plate roller seat mounting frame 5 in the vertical direction of the frame 2.

[0055] like Figure 2 , 3 As shown, further, the adjusting portion 6 also includes a sliding mechanism 63, the sliding mechanism 63 includes a track 631 arranged on the plate roller seat mounting frame 5 and a slider 632 slidably arranged on the track 631, and the calibration seat 3 is detachably mounted on the slider 632; the first calibration seat 31 and the second calibration seat 32 are pushed along Figure 2 The first calibration seat 31 and the second calibration seat 32 are moved in the opposite direction of the X-axis to increase the position distance between the first calibration seat 31 and the second calibration seat 32, so as to remove the calibration shaft 1 passing through the two; the first calibration seat 31 and the second calibration seat 32 are pushed closer to each other to install the calibration shaft 1 on the calibration seat 3; so that the calibration shaft 1 is easy to disassemble, maintain and repair.

[0056] like Figure 2 As shown, specifically, a positioning block 633 is provided on the side wall of the slider 632 protruding from the upper surface of the slider 632, and the positioning block 633 is used to calibrate that the vertical surface of the side wall of the slider 632 and the vertical surface of the side wall of the calibration seat 3 are on the same vertical line, thereby calibrating the position of the calibration seat 3 on the slider 632;

[0058] The d and D satisfy the relationship: d=D.

[0059] When the calibration seat 3 is replaced by the plate roller seat 4, the holes on the plate roller seat 4 for fixing the two ends of the plate roller coincide with the axis of the alignment hole 30 on the calibration seat 3, ensuring that when the plate roller is installed on the plate roller seat 4, the axis of the plate roller coincides with the axis of the calibration shaft 1, thereby improving the assembly accuracy of the plate roller seat;

[0060] like Figure 1 As shown, further, the length of the calibration axis 1 is greater than or equal to the maximum distance from the first calibration seat 31 to the second calibration seat 32, which further improves the stability of the fixture structure.

[0062] Specifically, when installing or removing the plate roller on the plate roller seat 4, the process is consistent with the above-mentioned process of operating the calibration seat 3 on the sliding mechanism 63, so that the plate roller is easy to disassemble, maintain and repair.
