Description

[Detailed description of the device]

[0001]

[Industrial application]

 This device can be used to measure the distance between two surfaces with a slight slope, such as in mold parts (cabinet, core block), or between a surface with a slope and a surface without a slope. The present invention relates to a measuring device for measuring.

[0002]

[Prior Art]

 FIG. 5 shows a method of measuring the distance between two sloped surfaces with a conventional measuring device, a micrometer. In the figure, 1 is a micrometer, 2 and 2a are measuring elements of the micrometer 1, 3 is an object to be measured, 4 and 5 are surfaces having a gradient that constitutes the object to be measured 3, and 6 and 7 are slopes. The slopes of the surfaces 4 and 5 having the angle .gtoreq.

As shown in the figure, in order to measure the distance 8 between two sloped surfaces, a probe of a micrometer 1 is applied to the ends of the two surfaces 4 and 5. If the slopes 6 and 7 are small, the error will be smaller than the required accuracy, and even such a method can be measured in principle.

[0004]

[Problems to be solved by the device]

 As shown in Fig. 5, when there was no measuring instrument for the distance between the sloped surfaces in the past, when we tried to measure with a general micrometer, the contact point and the measuring surface did not come into complete contact, so the micrometer It was impossible to obtain the exact size because the positioning of the was unstable. Therefore, if accurate dimensions were to be obtained, the only way to obtain measurements was with an optical measuring instrument, which required the workpiece being machined to be temporarily removed from the machine.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a slope distance measuring device that can accurately measure the size between slopes without removing the work piece from the machine. To aim.

[0006]

[Means for Solving the Problems]

 The inter-slope distance measuring device according to the present invention is equipped with a replaceable stylus having the same slope as the slant and a known size, and after the stylus is aligned with the reference position, the size of the scale Is preset so that the dimension between slopes can be compared and measured against the dimension of the contact point, and both the inside and outside dimensions between slopes can be measured.

[0007]

[Action]

 Since the tracing stylus attached to the measuring instrument in this invention has the same angle as the slope, it can be stably positioned on the slope and the dimension between the slopes can be accurately measured.

【Example】

 Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 2, 9 is a measuring instrument according to the present invention, 10 and 11 are measuring elements attached to the measuring instrument 9, 12 and 13 are measuring elements having the same angle of inclination as the slopes 4 and 5 for measuring dimensions. There are 10 and 11 known dimensions. Further, in FIG. 3, 14 is a dimension indicated by the measuring instrument.

Next, a method for measuring the outer dimension between two slopes using the measuring device according to the present invention will be described. First, as shown in Fig. 2, after attaching the measuring elements 10 and 11 having the same angle as the slope to be measured to the measuring instrument 9, the two measuring elements are brought into contact with each other, and the dimension indicated by the measuring instrument at this time is set to 0. And Next, as shown in FIG. 3, the contact points 10 and 11 of the measuring instrument 9 are brought into contact with the sloped surfaces 4 and 5 constituting the object to be measured 3 to read the dimension 14 indicated by the measuring instrument. If the size value at this time is A _1, the distance X ₁ 8 between the surfaces 4 and 5 with gradient calculated as follows using the sizes 12, 13 of the probe 10, 11 shown in FIG. 2 Be done. X ₁ = A ₁ + B ₁ + C ₁

Next, a case of measuring the inner dimension between the surfaces having two gradients will be described. In FIG. 4, 10a and 11a are measuring elements attached to the measuring device in the opposite direction to that of FIG. 2, and 12a, 13a and 15, 16 are known dimensions of the measuring elements 10a and 11a. In FIG. 5, 3a is the object to be measured, 4a and 5a are the surfaces having the gradients forming the object to be measured 3a, 6a and 7a are the gradients of 4a and 5a having the gradient, and 8a is the distance to be measured.

FIG. 4 shows a state in which the measuring elements 10a and 11a are attached to the measuring instrument 9 with their directions reversed from those shown in FIG. 3 and the measuring elements 10a and 11a are brought into contact with each other. The dimension indicated by the measuring instrument at this time is 0. Next, as shown in FIG. 5, the contact points 10a and 11a of the measuring instrument 9 are brought into contact with the sloped surfaces 4a and 5a of the object to be measured 3a, and the dimensions indicated by the measuring instrument are read. If the dimension at this time is A ₂ , the dimension X ₂ 8a between the sloped surfaces 4a and 5a can be calculated by using the previously known dimensions 12a, 13a and 15, 16 of the tracing stylus 10a, 11a. Is asked. X ₂ = A ₂ + B ₂ + C ₂

[0012]

[Effect of the device]

 As described above, it is possible to measure the distance between two slopes by using a measuring instrument equipped with a probe having the same slope as the slope forming the object to be measured. Since the contact point is attachable to and detachable from the measuring instrument, it is possible to measure the distance between slopes with an arbitrary slope by making a contact point having the same slope as the angle of the slope. It is also possible to measure the angle between a vertical plane without slope and a slope.
