Description

  The present invention relates to a measuring device and a measuring system capable of storing measurement data.

  A dial gauge is known as one of measurement devices for performing comparison measurement. A dial gauge generally measures the displacement of linear movement of a spindle provided with a probe at its tip, but some measure the displacement of the swing of a lever-like probe (lever type Dial gauge).

  The dial gauge can be classified according to the display format of the measurement result in addition to the classification method as described above. Specifically, there are a pointer-type dial gauge that displays a displacement amount by a rotation angle of a pointer, and a digital-type dial gauge that digitally displays a displacement amount (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 10-103901

  In the conventional dial gauge, for example, a measurement for detecting the presence or absence of a shake of a spindle or the like performed for centering, a measurement for obtaining a rough magnitude of displacement, a measurement for performing a pass / fail judgment by a limit value, etc. Can be done easily and quickly. However, in the case of measurement for grasping the shape of the object to be measured such as roundness, flatness, and straightness, the displacement amount in the process of sliding the probe in the relatively constant direction on the surface of the object Since it is necessary to read the trend in detail, it is necessary to slide slowly and the measurement takes time.

  Moreover, since the displacement amount displayed on the dial gauge fluctuates by sliding the measuring element, when it is desired to accurately grasp the shape of the object to be measured or to use the measurement result after the fact, It is necessary to stop the sliding sequentially to confirm or record the displacement amount, which requires more time.

  The object of the present invention is to make it possible to rapidly measure when it is desired to grasp the shape of an object to be measured from the trend of displacement of the measurement element in the process of sliding the probe on the surface of the object to be measured It is an object of the present invention to provide a measuring device and a measuring system which make it possible to easily utilize measurement results.

  (6) The measurement data of a plurality of times is used as comparison measurement data comparing the reference measurement data and the reference measurement data, and the display control means superimposes the graph of the reference measurement data and the graph of the comparison measurement data It may be displayed.

  (7) Further, the display control means may cause the display means to display a graph indicating the positional transition of the difference between the reference measurement data and the comparison measurement data.

  Assuming that the reference measurement data is the measurement data of the master work and the comparison measurement data is the measurement data of the inspection target work to be compared with the master work, according to the present invention, how different is the state of the inspection target work from the master work It becomes possible to grasp visually.

  (8) The storage means stores measurement data of a plurality of times as one measurement data, with the amount of displacement for each predetermined cycle stored in the storage means from the start of measurement to the end of measurement, and the plurality of measurement data And a plurality of reference measurement data, which are measurement data for each of a plurality of reference measurement objects, and comparison measurement data, which is measurement data of an object to be compared with each reference measurement object; A standard measurement object to which the object to be measured is most similar is identified by comparing the transition of the displacement amount with the transition of the displacement amount in the respective reference measurement data as a scale, and the identified standard Information indicating the object to be measured may be displayed on the display means.

  According to the present invention, when each reference measurement object represents the type of the measurement object, it is possible to easily identify to which kind the object under measurement is most likely to belong.

  (9) A touch panel display may be adopted as the display means, and execution start and end of measurement may be instructed by touch input to the touch panel display.

  This facilitates the instruction input operation of measurement start and measurement end.

  (10) The present invention is preferably applied to, for example, a spindle type dial gauge or a lever type dial gauge.

First Embodiment
FIG. 1 shows an example of the appearance of the measuring apparatus 100 of the present invention, and FIG. 2 shows an example of the internal configuration of the main body case 110. As shown in FIG. The measuring apparatus 100 includes a main body case 110, a spindle 120, a probe 121, a detection unit 130, a data collection unit 140, a storage unit 150, a display control unit 160, and a display unit 161.

  The spindle 120 is provided on the main body case 110 so as to be axially displaceable. At the tip of the spindle 120, a probe 121 is provided which abuts against the workpiece W at the time of measurement, and the displacement of the probe 121 due to the unevenness of the workpiece W is reflected in the displacement of the spindle 120.

  The detection means 130 detects the amount of displacement of the spindle 120 while the probe 121 slides on the surface of the object W in a relatively constant direction from the start of measurement to the end of measurement. The displacement amount may be detected by any method such as a photoelectric method, a capacitance method, or an electromagnetic method as long as the method can output a displacement amount as an electric signal.

  The data collection means 140 acquires the amount of displacement detected by the detection means 130 in a predetermined cycle, and sequentially stores the amount in any storage means 150.

  The display control means 160 causes the display means 161 to display predetermined information based on the displacement amount for each predetermined cycle.

  The function of the display control unit 160 can be realized, for example, by having the CPU in the measuring apparatus 100 and causing the CPU to execute a program in which the function of the display control unit 160 is described. In this case, advanced processing and analysis can be performed according to the description content of the program, and can be reflected on the display on the display means 161.

  By adopting a display capable of graphic display as the display means 161, various information can be flexibly displayed. For example, the amount of displacement for each predetermined cycle can be displayed in the form of a graph showing the positional transition of the amount of displacement.

In the process, the displacement amount detected by the detection means 130 is acquired by the data collection means 140 in a predetermined cycle and sequentially stored in the storage means 150, and the display control means 160 A graph as shown in FIG. 4B showing transition is displayed on the display means 161.

  According to the measuring apparatus 100 of the first embodiment described above, since the displacement amount detected by the detection unit is sequentially stored in the storage unit, reading and recording operations of the displacement amount during measurement become unnecessary, so measurement can be performed. Can be done promptly. Further, since the measurement results are stored in the storage means, they can be easily used.

  When the display control means 160 causes the display means 161 to display a graph, the graph may be expanded each time the data collection means 140 acquires the displacement amount at a predetermined cycle.

  Thus, the shape of the object W can be grasped in real time during measurement.
