In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0028] As shown in Figure 1 and Figure 2 The utility model provides a corrugation measurement auxiliary device, the corrugation measurement auxiliary device includes bearing assembly 1 and support component 2, bearing assembly 1 includes the lap joint plate 11, the lap joint plate 11 has oppositely arranged lap joint plane 111 and bearing plane 112, and the lap joint plane 111 is used to abut the surface to be measured, and the bearing plane 112 is used to support the corrugation tester;Support component 2 includes support rod 21 and adjusting part 22, support rod 21 is threaded in bearing assembly 1, and adjusting part 22 can drive bearing assembly 1 to move along support rod 21.

[0029] Because the lap joint plate 11 has oppositely arranged lap joint plane 111 and bearing plane 112, and the lap joint plane 111 is used to abut the surface to be measured, and the bearing plane 112 is used to support the corrugation tester, the corrugation tester can be placed on the bearing assembly 1 to measure the surface to be measured. At the same time, because the support rod 21 is threaded in the bearing assembly 1, the support rod 21 can support the bearing assembly 1, without manually holding the corrugation tester to measure the corrugation of the surface to be measured, thereby greatly improving the accuracy of the measurement. Because the support rod 21 is threaded in the bearing assembly 1, and the adjusting part 22 can drive the bearing assembly 1 to move along the support rod 21, the adjusting part 22 can adjust the position of the bearing assembly 1 on the support rod 21, so that the bearing assembly 1 can be smoothly set up on the surface to be measured at different heights, thereby accurately measuring the surface to be measured. Because the bearing assembly 1 is set up on the surface to be measured, and the support rod 21 supports the bearing assembly 1, the corrugation measurement auxiliary device can assist in supporting the corrugation tester, so that the corrugation tester can stably and accurately measure the surface to be measured without being limited by the size of the surface to be measured, thereby expanding the application range of the corrugation tester, and having strong practicality.

[0030] Specifically, as shown in Figure 1 , a detection slot 113 for the detection head of the corrugation tester is formed on the lap joint plate 11, and the detection slot 113 extends along the length direction of the lap joint plate 11. The detection slot 113 can facilitate the passage of the detection head of the corrugation tester, thereby greatly facilitating detection, so that the corrugation tester can smoothly detect the corrugation of the entire surface to be measured.

[0031] Further, as shown in Figure 1As shown, the bearing assembly 1 also includes a connecting part 12, which is connected to the overlapping plate 11. The overlapping plate 11 is a flat plate structure. One end of the overlapping plate 11 is placed on the surface to be measured, and the other end of the overlapping plate 11 is connected to the connecting part 12 and supported by the support rod 21, so that the bearing assembly 1 can stably support the waviness meter.

[0032] The specific structure of the adjusting member 22 can be set according to actual needs, as long as it can fix the position of the connecting part 12 on the support rod 21 and drive the connecting part 12 to move along the support rod 21. For example, Figure 1 and Figure 2 As shown, the connecting part 12 has a mounting through hole 121. The adjusting component 22 includes a first nut 221 and a second nut 222. The support rod 21 passes through the mounting through hole 121. The first nut 221 is threaded to the support rod 21 and abuts against the upper surface of the connecting part 12. The second nut 222 is threaded to the support rod 21 and abuts against the lower surface of the connecting part 12. The upper and lower surfaces are two vertically opposite surfaces of the connecting part 12. The position of the connecting part 12 on the support rod 21 is fixed by the abutment of the upper and lower surfaces of the connecting part 12 by the first nut 221 and the second nut 222. When it is necessary to adjust the position of the connecting part 12 on the support rod 21, the position of the connecting part 12 can be adjusted by screwing the first nut 221 and the second nut 222. The structure is simple and the operation is convenient.

[0033] Before placing the waviness meter on the bearing assembly 1 for measurement, the level of the overlapping plate 11 needs to be adjusted so that the bearing plane 112 is in a horizontal state to ensure the accuracy of the waviness meter measurement on the bearing plane 112.

[0034] In order to improve the structural strength of the load-bearing component 1 and prevent the adjustment component 22 from being damaged by excessive compression during the adjustment process, the thickness of the connecting part 12 is greater than the thickness of the overlapping plate 11 along the insertion direction of the support rod 21.

[0035] To further improve the adjustment convenience of the adjusting component 22, an elastic element is sandwiched between the second nut 222 and the connecting part 12. The elastic element can apply an elastic force to the connecting part 12 along the length of the support rod 21. When it is necessary to adjust the position of the bearing component 1 downward, firstly, the second nut 222 is screwed down to move the second nut 222 downward along the support rod 21. Then, the first nut 221 is screwed down in the same direction to press and fix the connecting part 12 downward. When it is necessary to adjust the position of the bearing component 1 upward, firstly, the first nut 221 is screwed up to move the first nut 221 upward along the support rod 21. The connecting part 12 will then move upward along the support rod 21 under the elastic force of the elastic element. Then, the second nut 222 is screwed down in the same direction to press the elastic element onto the connecting part 12, thereby fixing the position of the connecting part 12 on the support rod 21. There is no need to manually pull the connecting part 12 upward, making the operation convenient, time-saving, and labor-saving. Specifically, the elastic element is a compression spring, which is sleeved on the support rod 21, and its two ends abut against the connecting part 12 and the second nut 222 respectively.

[0036] Specifically, such as Figure 1 As shown, the mounting through hole 121 is an elongated hole that extends along the length of the overlapping plate 11, allowing the support rod 21 to move within the mounting through hole 121. This reduces the assembly difficulty of the connecting part 12 and the support rod 21. At the same time, the support component 2 can adjust its relative position to the bearing component 1 according to the structure and surface condition of the workpiece to be measured, thereby expanding the applicability of the waviness measurement auxiliary device.

[0037] The connecting part 12 and the overlapping plate 11 are integrally formed, which ensures the structural strength of the corrugation measurement auxiliary device.

[0038] Furthermore, such as Figure 1 As shown, the support component 2 is provided in multiple sets, with multiple support rods 21 arranged in parallel and at intervals. Multiple sets of support components 2 can provide more stable support for the load-bearing component 1, ensuring the stability and reliability of the measurement process.

[0039] Furthermore, such as Figure 1 As shown, a portion of the bearing plane 112 is recessed to form a receiving groove 114. The side wall of the receiving groove 114 is used to abut against the waviness meter. The receiving groove 114 is used to place the waviness meter, thereby ensuring the stability of the waviness meter during the measurement process.

[0040] Specifically, both the connecting part 12 and the overlapping plate 11 are regular cuboid structures. The detection slot 113 of the overlapping plate 11 extends along the length of the overlapping plate 11 to the end face of the overlapping plate 11, so that the overlapping plate 11 forms a symmetrical fork-shaped structure. When the waviness meter is placed in the receiving groove 114, the two sides of the waviness meter abut against the side wall of the receiving groove 114, so that the waviness meter can be stably placed in the receiving groove 114, ensuring the stability of the waviness meter in the whole measurement process. The detection head of the waviness meter passes downward through the detection slot 113 to detect the surface to be measured.

[0041] Specifically, flexible pads are provided on the side wall and bottom of the receiving groove 114. The flexible pads can play a buffering role, protect the waviness meter, and prevent wear on the waviness meter and the bearing component 1 itself when the waviness meter is placed.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
