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 the measuring devices for performing comparative measurement. Dial gauges generally measure the amount of displacement of the linear motion of a spindle provided with a stylus at the tip, but some dial gauges measure the amount of displacement of the swing of a lever-shaped stylus (the lever type). Dial gauge).

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

Since it is necessary to read the trend in detail, it is necessary to slide slowly and it takes time to measure.

In addition, the amount of displacement displayed on the dial gauge fluctuates by sliding the stylus, so if you want to accurately grasp the shape of the object to be measured or if you want to use the measurement results after the fact, The sliding must be stopped sequentially to confirm or record the displacement amount, which requires more time.

An object of the present invention is to enable rapid measurement when it is desired to grasp the shape of the object to be measured from the trend of the displacement amount of the stylus in the process of sliding the stylus 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 that enable easy use of measurement results.

A stylus 121 that comes into contact with the object to be measured W at the time of measurement is provided at the tip of the spindle 120, and the displacement of the stylus 121 due to the unevenness of the object W to be measured is reflected in the displacement of the spindle 120.

The detecting means 130 detects the displacement amount of the spindle 120 in the process in which the stylus 121 slides on the surface of the object to be measured W in a relatively constant direction from the start of the measurement to the end of the measurement. As the displacement detection method, any method may be adopted as long as the displacement amount can be output as an electric signal, such as a photoelectric type, a capacitance type, and an electromagnetic type.

The data collecting means 140 acquires the displacement amount detected by the detecting means 130 at a predetermined cycle, and sequentially stores the displacement amount in an arbitrary 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.
