[0053] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0054] like Figures 1 to 7 As shown, an embodiment of the present invention provides a honeycomb thickness gauge, comprising:

[0055] A measuring platform 1, a honeycomb panel 9 is placed on the surface of the measuring platform 1;

[0056] A carrier frame, the carrier frame is located above the measuring platform 1;

[0057] A guide seat 4 connected to the carrier frame;

[0058] A displacement rod assembly 6 is slidably connected to the guide seat 4, and the bottom end of the displacement rod assembly 6 abuts against the surface of the honeycomb panel 9. When the honeycomb panel 9 moves on the surface of the measuring platform 1, the displacement rod assembly 6 rises and falls as the thickness of the honeycomb panel 9 changes;

[0059] A dial indicator 5 connected to the guide seat 4 and having an adjustable height, wherein the probe of the dial indicator 5 abuts against the upper end of the displacement rod assembly 6 to measure the lifting and lowering displacement of the displacement rod assembly 6 .

[0060] In this embodiment, before measuring the honeycomb panel 9, a height block having the same standard thickness as the honeycomb panel 9 is placed on the surface of the measuring table 1, so that the bottom end of the displacement rod assembly 6 abuts against the upper surface of the height block, and the height of the dial gauge 5 is adjusted according to the upper end height of the displacement rod assembly 6, so that the probe of the dial gauge 5 abuts against the upper end of the displacement rod assembly 6, and the height adjustment, fixation and calibration of the dial gauge 5 are completed;

[0061] The honeycomb panel 9 is placed on the surface of the measuring platform 1, so that the bottom end of the displacement rod assembly 6 is in contact with the upper surface of the honeycomb panel 9, and the honeycomb panel 9 is pulled to move the honeycomb panel 9 on the surface of the measuring platform 1 along the measuring direction. When the thickness of the honeycomb panel 9 changes, the displacement rod assembly 6 will rise and fall. The rise of the displacement rod assembly 6 indicates that the actual thickness of the honeycomb panel 9 is greater than the standard thickness, and the fall of the displacement rod assembly 6 indicates that the actual thickness of the honeycomb panel 9 is less than the standard thickness. The displacement rod assembly 6 rises and falls with the thickness change of the honeycomb panel 9. The lifting displacement of the displacement rod assembly 6 is measured by the dial indicator 5, thereby indirectly measuring the thickness change of the honeycomb panel 9. After completing a movement measurement in the measuring direction, the honeycomb panel 9 is moved along the adjustment direction, and the honeycomb panel 9 is continued to be moved along the measuring direction. The above process is repeated until the thickness change measurement of the entire honeycomb panel 9 is completed; wherein the measuring direction is the width direction of the measuring platform 1, that is, Figure 1 In the Y direction, the adjustment direction is perpendicular to the measurement direction and is the length direction of the measuring table 1, that is, Figure 1 Middle X direction;

[0062] The thickness change of the honeycomb panel 9 is reflected by the lifting and lowering change of the displacement rod assembly 6. The lifting and lowering displacement of the displacement rod assembly 6 is measured by the dial indicator 5 to realize the measurement of the thickness change of the honeycomb panel 9. The measurement operation is simple and convenient. By adjusting the height of the dial indicator 5, the measurement requirements of honeycomb panels 9 of different thicknesses can be met, and the application range is wide.

[0063] like Figure 1 As shown, in an optional embodiment of the present invention, a plurality of guide seats 4 are provided and distributed along the length direction of the measuring platform 1 .

[0064] In this embodiment, by providing a plurality of guide seats 4, displacement rod assemblies 6 and dial indicators 5, the thickness variation measurement of multiple locations of the honeycomb panel 9 can be realized at one time, which helps to improve the measurement efficiency;

[0065] In this embodiment, as a preference, a plurality of guide seats 4 are evenly distributed along the length direction of the measuring platform 1. After completing a measurement in a measuring direction, the adjustment is performed along the adjustment direction. When the measurement of the entire honeycomb panel 9 is completed multiple times, the plurality of guide seats 4 are evenly distributed along the length direction of the measuring platform 1. This enables uniform and sufficient measurement of the honeycomb panel 9, avoids repeated measurement, and further improves the measurement efficiency.

[0066] In this embodiment, the extension length of the support frame above the measuring platform 1 is at least greater than half of the length of the measuring platform 1; in practical applications, two groups of support frames can be selected and symmetrically distributed based on the length midline of the measuring platform 1, and multiple guide seats 4, displacement rod assemblies 6 and dial indicators 5 can be evenly distributed to further improve the measurement efficiency.

[0067] like Figures 5 to 7 As shown, in an optional embodiment of the present invention, each guide seat 4 includes:

[0068] A fixing seat 41 connected to the carrier frame, wherein a vertically extending guide hole 402 is provided through the upper surface of the fixing seat 41;

[0069] A fixing block 43 connected to the upper surface of the fixing seat 41, the fixing block 43 is provided with a guide groove 44, and the guide groove 44 is connected to the guide hole 402;

[0070] Each displacement rod assembly 6 connected to the guide seat 4 includes:

[0071] A lifting rod 61 slidably disposed inside the guide hole 402;

[0072] A guide block 66 connected to the upper end of the lifting rod 61, the guide block 66 is slidably matched with the guide groove 44, and the upper surface of the guide block 66 is in contact with the probe of the dial indicator 5;

[0073] A connecting frame 64 connected to the bottom end of the lifting rod 61, the connecting frame 64 is a door-shaped structure;

[0074] The roller 65 installed inside the connecting frame 64 is rotatably connected to the surface of the honeycomb panel 9 , wherein the roller 65 extends along the length direction of the measuring platform 1 .

[0075] In this embodiment, during measurement, the roller 65 abuts against the upper surface of the honeycomb panel 9. As the thickness of the honeycomb panel 9 changes, the roller 65 drives the lifting rod 61 to rise and fall inside the guide hole 402. The guide block 66 rises and falls with the lifting rod 61. The lifting displacement of the guide block 66 is measured by the dial indicator 5 to achieve the measurement of the thickness change of the honeycomb panel 9.

[0076] The roller 65 is in contact with the honeycomb panel 9, and rolling friction can be used to reduce the wear on the honeycomb panel 9; the lifting rod 61 is limited and guided by the sliding cooperation between the guide block 66 and the guide groove 44, which can prevent the direction of the roller 65 from changing when the honeycomb panel 9 is moved, thereby ensuring that the thickness change measurement of the honeycomb panel 9 is carried out smoothly and accurately;

[0077] In the present embodiment, preferably, the distance between two adjacent displacement rod assemblies 6 is less than or equal to the length of the roller 65; after completing a measurement in the measuring direction, adjustment is performed along the adjustment direction. When the measurement of the entire honeycomb panel 9 is completed multiple times, the adjustment distance along the adjustment direction can be the length of the roller 65. When the distance between two adjacent displacement rod assemblies 6 is less than or equal to the length of the roller 65, after completing a measurement in the measuring direction, when the honeycomb panel 9 is moved along the adjustment direction, the roller 65 can be completely in contact with the surface of the honeycomb panel 9 that has not been measured, thereby ensuring a complete and sufficient measurement of the honeycomb panel 9.

[0081] In this embodiment, when measuring, the elastic force of the spring 62 is used to press down the boss 63 so that the roller 65 can always be in full contact with the surface of the honeycomb panel 9, thereby ensuring the accuracy of measuring the thickness change of the honeycomb panel 9.

[0082] like Figure 6 As shown, in an optional embodiment of the present invention, the honeycomb thickness gauge further includes:

[0085] A mounting beam 8 connected to the mounting plate 7, the mounting beam 8 extending horizontally above the fixing block 43;

[0086] A placement through hole 81 is formed on the upper surface of the mounting beam 8, and a sleeve of the dial gauge 5 is inserted into the placement through hole 81;

[0087] A fastening bolt 82 is threadedly connected to the outside of the mounting beam 8 , and an end of the fastening bolt 82 extends into the placement through hole 81 and is in close contact with the sleeve of the dial indicator 5 .

[0088] In this embodiment, the sleeve of the dial gauge 5 is inserted into the placement through hole 81, and the fastening bolt 82 is screwed so that the fastening bolt 82 is in close contact with the sleeve of the dial gauge 5, thereby achieving fixed installation of the dial gauge 5;

[0089] By loosening the adjusting bolt 72, the height of the mounting plate 7 can be adjusted through the adjusting slot 71, thereby achieving the height adjustment of the dial indicator 5, so that the probe of the dial indicator 5 abuts against the upper surface of the guide block 66, ensuring that the dial indicator 5 accurately measures the lifting and lowering displacement of the displacement rod assembly 6, and can meet the thickness change measurement requirements of honeycomb panels 9 of different thicknesses.

[0090] like Figure 7 As shown, in an optional embodiment of the present invention, a vertically extending slide rail 73 is formed on the mounting plate 7 , and the slide rail 73 is slidably matched with the slide groove 45 on the side of the fixing block 43 .

[0091] In this embodiment, the mounting plate 7 can be guided in the vertical direction by the sliding cooperation between the slide rail 73 and the slide groove 45. When the height of the mounting plate 7 is adjusted, it can ensure that the probe of the dial indicator 5 is vertically downward, ensuring that the dial indicator 5 can accurately measure the lifting and lowering displacement of the displacement rod assembly 6.

[0099] By adjusting the height of the mounting seat 2, the height of the load beam 3 can be adjusted, and finally the height of the dial indicator 5 can be adjusted, which can meet the measurement requirements of the thickness change of the honeycomb panels 9 of different thicknesses;

[0100] In this embodiment, the placement platform 12 may be a marble platform, or other platforms that can meet the needs of moving the honeycomb panel 9 and measuring the thickness change, which is not specifically limited here.
