However, the configuration, numerical values, process flow, functional elements, and the like described in the following embodiments are merely examples, and modifications and changes are free, and the technical scope of the present invention is described in the following description. It is not intended to be limited.

[First Embodiment]
<About prerequisite technologies>
For example, when a steel plate damaged in an automobile accident or the like is corrected by sheet metal or painting, it is common to check the finished surface by relying on the sense of the hand or fingertip of a sheet metal engineer or paint engineer. . Therefore, even if an inexperienced sheet metal engineer or paint engineer receives guidance from a skilled engineer, even if he / she evaluates the quality of the sheet metal or paint performed by the skilled engineer, there is a difference in the technical level. In some cases, it was not possible to judge whether the evaluation given was appropriate. In addition, it has been difficult for users, insurance companies, and the like to objectively evaluate restoration conditions, work costs, and the like. In other words, “high” and “low” with respect to the reference surface of the sheet metal surface or the painted surface can be judged as an engineer's sensation, but it is difficult to express or evaluate that sensation numerically. It was.

  Therefore, there is a need for equipment that can display numerically the accuracy (high and low) of the finished surface of the sheet metal and the finished surface of the paint. With such a device, training of sheet metal engineers, confirmation of technical capabilities, technical capabilities It can be used to improve. In addition, if an examination system and a certification system using such devices become widespread, it will be meaningful to both engineers and users, and the user can easily grasp the technical level of repair shops etc. by numerical values. . Therefore, for example, if the damage caused by an automobile accident is large, a factory with a high technical level can be selected even if the fee is somewhat high. On the other hand, if the damage is small and inconspicuous, a low-cost factory can be selected even if the technical level is low. Therefore, the user can select a repair shop, a sheet metal engineer, a paint engineer, or the like according to his / her own purpose and budget using the evaluation by such an apparatus as one index.

<Technology of this embodiment>
A measuring apparatus 100 as a first embodiment of the present invention will be described with reference to FIGS. 1A to 7. FIG. 1A is a front perspective view illustrating the outline of the overall configuration of the measuring apparatus 100 according to the present embodiment. FIG. 1B is a rear perspective view for explaining the outline of the overall configuration of the measuring apparatus 100 according to this embodiment. FIG. 2 is a front perspective view for explaining an outline of another overall configuration of the measuring apparatus 100 according to the present embodiment. In the following description, the measurement of the surface accuracy of the sheet metal surface will be described as an example, but it can also be applied to the measurement of the surface accuracy of the painted surface.

  The measuring apparatus 100 is an apparatus that is attached to a measurement object and measures the unevenness of the surface 140 of the measurement object. As shown in FIG. 1, the measuring apparatus 100 includes an indicator 101, a slider 102, a guide rail 103, and a support unit 104.

  The indicator 101 has a mechanism in which a measuring element such as a shaft 111 slides up and down, and depending on how much the shaft 111 moves in a plus (or minus) direction with respect to a certain reference point, The unevenness of the surface 140 is measured. As such an indicator 101, for example, a digital type indicator is typical, but an analog type indicator or the like may be used as long as the unevenness of the surface 140 of the object to be measured can be measured. Note that, here, the indicator 101 including the sliding probe such as the shaft 111 has been described as an example, but the measuring instrument applicable as the indicator 101 is not limited to this, and for example, laser light or ultrasonic waves are used. The measuring device used may be used as the indicator 101. Further, the tip of the shaft 111 may have a shape that does not damage the surface 140, and a protective member such as a cover may be provided at the tip.

  The indicator 101 is connected to a cable 150 for transferring measured data to an external device. The cable 150 is connected to, for example, a personal computer (PC) or a mobile terminal (smart phone, PDA (Personal Data Assistant, Personal Digital Assistant)) not shown. The data transferred from the indicator 101 is processed by a personal computer or the like, and the processing result is displayed on a display or the like.

  An indicator 101 is attached to the slider 102. In the present embodiment, the indicator 101 and the slider 102 have been described as separate configurations, that is, the configuration in which the indicator 101 is attached to the slider 102. However, the indicator 101 and the slider 102 may be integrally formed. .

  The guide rail 103 is a member that regulates the moving direction of the slider 102 and guides the slider 102 in a predetermined moving direction. For example, in this embodiment, the guide rail 103 guides the slider 102 in the left-right direction of FIG. 1A (FIGS. 1B and 2). As the slider 102 moves, the indicator 101 also moves in the left-right direction. Accordingly, the indicator 101 measures the unevenness of the surface 140 at a predetermined interval (pitch) while moving on the surface 140 of the object to be measured.

  The support unit 104 is a member that supports the guide rail 103 and fixes the guide rail 103 on the measurement target so that the guide rail 103 does not move on the measurement target during measurement by the indicator 101. The support portion 104 has a gently curved shape such that the contact portion 141 that contacts the surface 140 of the object to be measured has a convex shape with respect to the surface 140. Thus, by making the shape of the contact portion 141 convex or curved, the support portion 104 comes into contact with the surface 140 at one point, so that the guide rail 103 is stabilized on the object to be measured.

  Furthermore, if the contact portion 141 includes a magnet (magnetic material), the guide rail 103 can be more stably fixed to the object to be measured. Thus, if a magnet is used for the contact portion 141, the surface accuracy of the surface 140 can be easily measured even if the surface 140 of the object to be measured is a vertical surface. Further, if the contact surface of the contact portion 141 is coated with a resin or the like, or the contact portion 141 itself is made of a soft member such as rubber, the surface 140 of the object to be measured is not damaged. Note that the contact portion 141 is not limited to a curved surface shape, and may have a tapered shape that is inclined from the outside to the inside as shown in FIG. 2, and may sit on the surface 140 of the object to be measured. If it is a shape, it can be set as various shapes.

  FIG. 3 is a front view illustrating the configuration of the measuring apparatus 100 according to the present embodiment. The slider 102 includes a magnet 121. By providing the magnet 121 on the slider 102, the slider 102 and the guide rail 103 come into close contact with each other. Accordingly, the indicator 101 and the slider 102 can be prevented from falling off the guide rail 103, the slider 102 from being lifted from the guide rail 103, and the slider 102 from being rattled, so that a reduction in measurement accuracy can be prevented.

  Here, an example in which the magnet 121 is provided on the slider 102 side has been described, but the magnet 121 may be provided on both the slider 102 and the guide rail 103 or on the guide rail 103 side. In the case where the magnet 121 is provided on one of the slider 102 and the guide rail 103, it is preferable that a material that does not provide the magnet 121 is made of a material that sucks the magnet 121. Further, instead of providing the magnet 121, a groove may be carved in the guide rail 103, a protrusion may be provided on the slider 102, and the slider 102 may be slid along the groove. And a guide rail 103 may be provided with a protrusion.

  FIG. 4 is a top view illustrating the configuration of the measuring apparatus 100 according to the present embodiment. The slider 102 slides in the direction of the arrow in the figure along the guide rail 103 that restricts the moving direction of the slider 102.

  Three support portions 104 are provided to support the guide rail 103 at three points. More specifically, one support portion 104 is provided at the lower portion of one end portion of the guide rail 103, and the remaining two support portions 104 are arranged from the lower portion of the other end portion of the guide rail 103 to the top and bottom of FIG. It is provided at a position protruding in the direction.

  The position where the support portion 104 is provided is not limited to the position shown here, and the guide rail 103 is prevented from being displaced in the vertical and horizontal directions in FIG. 4, and the guide rail 103 is stably placed on the object to be measured. It may be provided at any position as long as it can be kept. Further, by supporting the guide rail 103 at three points in this way, it is possible to effectively prevent the guide rail 103 from being displaced in the vertical direction and the horizontal direction in FIG. In the present embodiment, the example in which the three support portions 104 are provided to support the guide rail 103 has been described. However, the number of support portions 104 is not limited to this, and four or more support portions 104 may be provided. Two may be provided.

  FIG. 5 is a side view illustrating the configuration of the measuring apparatus 100 according to the present embodiment. As shown in FIG. 5, in this embodiment, the guide rail 103 has a U-shaped cross section. That is, the guide rail 103 is a columnar member having a U-shaped cross section. When the slider 102 moves while sliding, the indicator 101 also moves following the movement of the slider 102. Note that the cross-sectional shape of the guide rail 103 is not limited to a U-shape, and may be an L-shape, for example.

  Thus, since the indicator 101 can be moved on the object to be measured, the shaft 111 can be moved so as to trace the surface 140 of the object to be measured. Thus, since the shaft 111 traces the surface 140 of the object to be measured, the shaft 111 moves up and down in accordance with the unevenness of the surface 140 of the object to be measured, whereby the indicator 101 shows the unevenness of the surface 140 of the object to be measured. Can be measured. In order to improve the sliding of the slider 102, oil (lubricating oil) such as Lucene may be applied to the contact surface between the slider 102 and the guide rail 103. Further, when measuring an aluminum panel as an object to be measured, a support member 104 may be fixed to the object to be measured by attaching a magnet or the like to the back surface of the aluminum panel.

  FIG. 6 is a flowchart for explaining a processing procedure of data measured by the measuring apparatus 100 according to the present embodiment.

  In step S601, the measuring apparatus 100 is set on the surface 140 to be measured of the object to be measured, and the measurement of the surface 140 of the object to be measured is started while the indicator 101 is moved. Then, by moving the slider 102 on the guide rail 103, the indicator 101 is moved by a predetermined distance to obtain measurement data of the unevenness of the surface 140.

  In step S603, the measuring apparatus 100 determines whether the measurement is finished. If the measurement has not been completed (NO in step S603), the measuring apparatus 100 continues the measurement. If the measurement has been completed (YES in step S603), the measuring apparatus 100 proceeds to the next step. The determination by the measuring apparatus 100 as to whether or not the measurement is finished is, for example, determined that the measurement is being performed while the vertical movement of the shaft 111 continues, and the vertical movement of the shaft 111 is stopped on the contrary. It may be determined that the measurement has been completed. In addition, a user who is measuring using the measuring apparatus 100 may determine the end of the measurement. Further, whether or not the measurement is finished may be determined based on whether or not the slider 102 has moved.

  In step S605, the measuring apparatus 100 transfers the acquired measurement data to a data processing device such as a PC. Note that the measurement data may be transferred by the user of the measuring apparatus 100 operating a data transfer button or the like.

  In step S607, the PC that has received the measurement data transferred from the measurement apparatus 100 processes the acquired measurement data. Further, the measurement data may be evaluated based on the processed measurement data. In step S609, the PC displays the processed data on a display or the like and presents it to the user.

  FIG. 7 is a diagram for explaining an example of data processing of data measured by the measuring apparatus 100 according to the present embodiment. For example, the center position of three consecutive measurement points among a plurality of measurement points (A1, A2, A3, A4, A5...) Is calculated, and the smoothness of the surface 140 is determined based on the calculated center position. To do. Alternatively, the center position of three consecutive measurement points may be calculated, and the smoothness of the surface 140 may be determined based on the sum of the distances between the calculated center positions. In this case, for example, the smoothness of the surface may be determined based on the sum of the distances.

FIG. 8 is a diagram for explaining another example of data processing of data measured by the measuring apparatus 100 according to the present embodiment. For example, the difference (d ₁ , d ₂ , d ₃ ...) Between the target line 801 and the actual construction line 802 is calculated by the least square method (d ₁ ² + d ₂ ² + d ₃ ² +...). The smoothness of the surface 140 may be determined based on the calculation result. These determination results may be scored (scored).

  According to the present embodiment, even when the measurement surface is a curved surface, a vertical surface, or an inclined surface, it is possible to measure and determine the surface accuracy of a sheet metal surface, a painted surface, and the like with an inexpensive and simple apparatus. In addition, even an inexpensive device can easily and reliably perform highly accurate measurement and evaluation.
