In general, micrometers are widely used to precisely measure the outer dimensions or outer diameter dimensions of an object to be measured. Manually measuring and inspecting a large number of objects to be measured individually using this micrometer requires a lot of effort, increases measurement time, and is inefficient. Therefore, in most cases, a sampling inspection is sufficient. However, in the assembly of precision machines, it is expected that the accuracy of individual parts will be improved even more. In order to obtain quick and reliable measurement results of the object to be measured, there was a need for automated measuring equipment, but the higher the quality, the higher the price.
It was necessary to create a measuring device suitable for on-site inspection. To this end, as a result of the inventor's many years of research and experimentation, the practical use of an automatic dimension measuring device suitable for such purposes has been achieved. However, the digitally displayed measurement values constantly fluctuate during the measurement and are unstable, making it difficult to determine the dimensions and having an adverse effect on measurement accuracy, which is an important problem to be solved.

測定が開始する。 The measuring object detection device 43 includes a movable spindle 18
Since the tip of the fixed spindle 42 has a flat contact surface, the optical axis is provided on the axis, and when this optical axis is blocked by the object to be measured, the presence of the object to be measured is detected. The main control circuit 58 issues a command to the motor drive device 65 to move the moving spindle 18 to measure the outer dimensions of the object to be measured. Therefore, the measuring device 1 starts measuring the outer dimensions of the object to be measured.

お、本実施例では測定圧を200ｇｆ、500ｇｆ、
1000ｇｆの３種類とする。 Further, the measurement pressure selection device 38 can arbitrarily select the measurement pressure depending on the type of the object to be measured. That is, accurate dimensional measurement is possible by applying arbitrary contact pressure to the object to be measured by the moving spindle 18. Therefore, the light emitting element plate 40 and the light receiving element plate 4 provided with the shielding plate 39 in between
1 has three sets of light emitting elements 40A and light receiving elements 41A arranged at predetermined intervals in the axial direction, so for example, one set closest to the shielding plate 39 is selected and activated, and the remaining two sets are operated. When stopping the operation, the member 7 to be sent after the moving spindle 18 contacts the object to be measured is moved to the position where the shielding plate 39 is the closest one.
It stops at a position where the light emitting element 40A and light receiving element 41A of the set are interrupted. Therefore, the pressing force of the spring 27 is the smallest. On the other hand, if the pair furthest from the shielding plate 39 is selected, the pressing force of the spring 27 will be the largest. This pressing force (measurement pressure) can be selected using a push button switch 5 provided on the cover 3A.
6 is displayed on the display lamp 51. In addition, in this example, the measurement pressure is 200gf, 500gf,
There are three types of 1000 gf.

し、その読み取りが容易である。 By the way, even if the predetermined measurement pressure selected by the measurement pressure selection device 38 is reached, even slight fluctuations in the measurement pressure may cause constant fluctuations in the indicated value, making it difficult to determine the dimensions. There is. Therefore, in response to the predetermined measured pressure detection signal from the measured pressure selection device 38, the counting control circuit 60 of the control calculation processing section holds the indicated value. This held indicated value continues to be held even if the object to be measured is removed from the automatic dimension measuring device 1, and the next new object to be measured is interposed between the movable spindle 18 and the fixed spindle 42 (not inserted). will be held until That is, when a new object to be measured is inserted between the moving and fixed spindles 18 and 42, the indicated value is released, measurement of the dimensions of this new object is started, and new dimensions are indicated. Ru. Therefore, the moving and fixed spindles 18,4
When the object to be measured is inserted between 2 and the measured pressure reaches a predetermined measurement pressure, the indicated value only fluctuates due to the measurement pressure fluctuation, and the indicated value is stabilized and easy to read.

示値を確実に読み取ることができる。 According to another embodiment of the invention, a new object to be measured is then inserted between the movable and stationary spindles 18, 42 to start the measurement and to a predetermined measuring pressure by the measuring pressure selection device 38. Depending on the predetermined measured pressure detection signal when the predetermined measured pressure is reached, the counting control circuit 60 of the control calculation processing section holds the indicated value. At the same time, the hold on the indicated value of the object to be measured is released. In other words, the holding of the indicated value of the previous object to be measured and the holding of the indicated value of the next new object to be measured are performed instantaneously. Therefore, fluctuations in the indicated value due to fluctuations in the measured pressure are almost completely avoided, and stable indicated values can be reliably read.

As described above, according to the present invention, when a predetermined measurement pressure is applied to the part to be measured, the control calculation processing section holds the indicated value on the display section, and the control calculation processing section performs the following operations. By holding the previous indicated value until it is detected that the object to be measured is interposed between the moving spindle and the stator, the object to be measured is inserted between the moving spindle and the stator, and the predetermined measurement is performed. The indicated value only fluctuates due to fluctuations in the measured pressure during a short period of time until the pressure is reached, and the indicated value is stabilized and easy to read. In addition, by holding the previous indicated value until it is detected that the next object to be measured is interposed between the moving spindle and the stator and a predetermined measurement pressure has been reached,
Since the holding of the indicated value of the previous measured object and the holding of the indicated value of the next new measured object are carried out instantaneously, fluctuations in the indicated value due to measurement pressure fluctuations are almost avoided, resulting in stable It is easy to read the indicated value. Therefore, the structure is simple, the handling is easy, the measurement is reliable, and the measurement performance can be improved.
