[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the specification of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] See also Figure 1-Figure 5 The utility model provides a flatness verification system for detecting the flatness of a measured plane, which comprises: a data detection device 1, a data processing device 2 connected to the data detection device 1, and a record generation device 3 connected to the data processing device 2.

[0030] Furthermore, the data detection device 1 is used to obtain contour data of the measured plane. In some embodiments, the contour data includes: an inclination angle of the measured plane relative to a horizontal plane and a distance between two groups of measurement points.

[0031] In some embodiments, the data detection device 1 includes: an auxiliary measuring tool 11 and an electronic level 12 compatible with the auxiliary measuring tool, wherein the auxiliary measuring tool 11 includes: a fixing component 111 and an adjusting component 112 movably connected to the fixing component 111 .

[0032] Furthermore, the fixing component 111 is a rectangular structure, and its upper surface is a flat measuring surface 1111. The measuring surface 1111 is abutted against the electronic level 12 and is used to assist in measuring the flatness of the measured plane. Specifically, the electronic level has a base measuring surface, which is used to measure the inclination of the measuring surface 1111 relative to the horizontal plane by abutting the base measuring surface against the measuring surface 1111.

[0033] In some embodiments, the electronic level 12 can be an inductive or capacitive electronic level. Specifically, the working principle of the inductive electronic level is: when the base of the level is tilted due to the tilt of the workpiece to be measured, the internal swing hammer will cause the voltage of the induction coil to change due to the movement. The measurement working principle of the capacitive electronic level is that the circular swing hammer can be freely suspended on a thin wire. The swing hammer is affected by the gravity of the earth's center and is suspended in a frictionless state. Electrodes are provided on both sides of the swing hammer. When the gaps are the same, the capacitance is equal. If the level is affected by the workpiece to be measured, the change of different distances between the two gaps will result in different capacitances and angles.

[0034] In some embodiments, a fixing groove 1112 and a fixing member 1113 adapted to the fixing groove 1112 are provided at the top of the fixing assembly 111 along the length direction, and the fixing member 1113 and the fixing groove 1112 are adapted to each other for fixing the electronic level 12. Further, the fixing member 1113 is an L-shaped structure, and the number of the fixing groove 1112 and the fixing member 1113 are both two groups, and the two groups of fixing members 1113 are arranged opposite to each other, and the two groups of fixing members 1113 are respectively abutted against the two ends of the electronic level 12, thereby limiting the position of the electronic level 12, so as to play the role of fixing the electronic level 12. In some embodiments, the fixing member 1113 and the fixing groove 1112 are interference fit, but the fixing member 1113 can move in the fixing groove 1112, so that the electronic level 12 can be fixed by adjusting the position of the fixing member 1113 in the fixing groove 1112.

[0035] In some embodiments, the number of the adjustment components 112 is two groups, the tops of which are respectively connected to the two sides of the bottom of the fixed component 111, and the bottoms are respectively in contact with the measured plane, and the fixed component 111 cooperates with the adjustment component 112 to measure the inclination of the measured plane relative to the horizontal plane by measuring the inclination of the measuring surface 1111 relative to the horizontal plane. Specifically, the plane where the measuring surface 1111 is located is always parallel to the contact surface between the adjustment component 1112 and the measured plane, so the inclination of the measured plane can be reflected by measuring the inclination of the measuring surface 1112.

[0036] Furthermore, a connecting groove 1114 is provided at the bottom of the fixing assembly 111 along the length direction, and a connecting piece 1121 adapted to the connecting groove 1114 is provided on the adjusting assembly 112, and the fixing assembly 111 and the adjusting assembly 112 are movably connected via the connecting groove 1114 and the connecting piece 1121. It should be noted that after the adjusting assembly 112 is movably connected to the fixing assembly 111, when the adjusting assembly 112 is in a horizontal state, the fixing assembly 111 is also in a horizontal state.

[0037] In some embodiments, two groups of measuring columns 1122 are further provided at the bottom of the adjustment component 112. When performing flatness verification, the measuring columns 1122 are used to abut against the measuring points on the measured plane. It can be understood that after the measuring columns 1122 abut against the measured plane, based on the flatness of the measured plane, the fixed component 111 will be tilted based on the flatness of the measured plane. The inclination angle of the measuring surface 1111 relative to the horizontal plane can be measured by the electronic level 12, and the inclination angle of the measured plane relative to the horizontal plane can be measured. The flatness of the measured plane can be calculated through the inclination angle of the measured plane relative to the horizontal plane and the distance between the two groups of measuring columns 22, thereby quickly and accurately verifying the flatness of the measured plane.

[0038] In some embodiments, the cross-sections of the connecting member 1121 and the connecting groove 1114 are both inverted trapezoidal structures that are wide at the top and narrow at the bottom. By setting the connecting member 1121 and the connecting groove 1114 to an inverted trapezoidal shape, on the one hand, the fixing component 111 and the adjusting component 112 can move relative to each other to adjust the distance between the two groups of measuring columns 1122. On the other hand, it can also ensure that the fixing component 111 and the adjusting component 112 will not be displaced in the vertical direction, thereby reducing the measurement error.

[0039] Further, the data processing device 2 is used to calculate the flatness according to the contour data of the measured plane and determine whether the flatness of the measured plane is qualified. In some embodiments, the data processing device 2 can compare the flatness technical results with the preset technical requirements to determine whether the flatness of the measured plane is qualified. For example, when the calculated flatness value of the measured plane is within a certain range, the flatness of the measured plane is determined to be qualified. In some embodiments, the data processing device 2 can also determine how many levels of standards the flatness of the measured plane meets according to preset technical requirements. For example, when the calculated flatness value of the measured plane is within a certain range, it meets the first or second level standard, thereby realizing the automated verification process of the flatness of the measured plane.

[0040] Furthermore, the record generating device 3 is used to generate a flatness verification result table according to the flatness calculation result and the judgment result, so as to facilitate the operator to analyze the verification result.

[0041] Finally, it should be noted that the embodiments of the present invention disclose only preferred embodiments of the present invention, which are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
