Abstract

(57) [Summary] [Problem] To measure the dimensions of a soft measurement object under uniform conditions by using a constant measurement pressure that does not deform the measurement object while preventing the influence of hand shake etc. on the measurement object. To be able to SOLUTION: In order to measure dimensions so as not to apply a deformation load to a measurement object (H), a link mechanism (A) prevents the influence of hand movement (G) and simultaneously moves one of the link mechanisms (A). The measurement pressure (E) generated by the measurement pressure mechanism (C) is moved by the measurement pressure mechanism (C) by the measurement pressure mechanism (B), and the measurement pressure (E) is limited by the measurement pressure completion position (D). is there.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention is a device that, when measuring the dimensions of a weak measuring object, prevents the influence of the camera shake on the measuring object and at the same time makes it easy to measure the dimensions at a constant pressure. Measurement errors can be reduced.

[0002]

[Prior art]

 When measuring the dimensions of a weak measuring object with a vernier caliper or micrometer, special care must be taken not to damage the measuring object due to hand shaking, etc. Since it was not possible, it was necessary to make a visual judgment, which caused variations in the measurement results and the measurement time had to be long.

[0003]

[Problems to be solved by the invention]

 In order to eliminate the above-mentioned problems, the idea of the present invention is to reduce the effect of camera shake on the measurement target by using a link mechanism, and at the same time, to enable dimensional measurement at a constant pressure.

[0004]

[Means to solve the problem]

 The invention will be described with reference to the drawings. The influence of the hand movement (G) on the measurement object (H) is reduced by the link mechanism (A), and the movement of the link mechanism (A) is reduced by the movement mechanism (B). By measuring and moving one side (F), the dimension can be measured at a constant pressure by applying the measurement pressure (E) to the measurement pressure completion position with the measurement pressure (E) generated by the measurement pressure mechanism (C). .

[0005]

[Action]

 The link mechanism can reduce the influence of the measurement hand shake on the measurement target, and the measurement pressure mechanism can perform measurement at a constant pressure, so that the measurement operation is simplified and the measurement error can be reduced.

[0006]

【Example】

 Embodiments will be described with reference to the drawings. Link mechanism (A) Two fulcrums of the four fulcrums are fixed to the calipers in parallel with the caliper measurement direction, one fulcrum is fixed to the calipers measuring and moving part, and the other fulcrum is fixed to the tip of the calipers. And the other two fulcrums are used for the movement mechanism (B) and the measurement pressure mechanism (C), and the measurement movement (G) is performed by moving the caliper dimension measurement movement part. F) Then, at the measurement pressure (E) indicated by the measurement pressure completion position (D), the dimension of the measurement object (H) can be measured.

[0007]

[Effect of the invention]

 The present invention not only measures various dimensions like normal dimension measurement, but also fixes the moving mechanism at the normal measurement dimension, performs the measurement operation, and judges the quality of the dimension to be measured based on the measurement completion position. At the same time, the scale position of the measurement pressure completion position is separated from the fulcrum so that enlargement detection can be performed, so that accurate measurement can be performed.
