Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a step difference measuring device for measuring step difference distances in various molded articles.

[Prior art]

The distance (height, depth, etc.) of the step difference may be measured in the press-formed product, the door building part, etc.
Here, as shown in FIG. 4, the step difference means that, for example, in the case of door construction of an automobile, when the door frame 80 is located with respect to the pillar 90 on the vehicle body side which is the reference object, The distance G between the surface 91 and the surface 81 of the door frame 80.

However, conventionally, there is a caliper as a means for measuring the distance (hereinafter referred to as a step difference) at such a stepped portion.

[Problems to be solved]

However, when measuring step differences using a caliper, it was necessary to lift the caliper and read the scale value every time the measurement was performed. In other words, it was difficult to read the scale with the caliper pressed against the molded product, fitting, etc. to be measured.

In addition, the reading of the measured values could be performed only from a fixed direction, that is, a direction substantially perpendicular to the plane scale. Also, because of these, it was not possible to make measurements in a short time.

In view of such a problem, the present invention aims to provide a step difference measuring instrument capable of reading the measurement scale from a wide field of view and capable of measuring the step difference even while being pressed against the measuring object.

[Means for solving problems]

The present invention comprises a transparent cylindrical slider guide provided with a main scale, an axial slider slidably inserted in the slider guide, and a bracket provided on the slider guide and having a reference surface. At the same time, the slider has a head at one end and a contactor at the other end, and a coil spring urged to push the slider back toward the head between the head and the slider guide. In addition, the slider has a measurement reference line and a vernier scale on its shaft portion, and the slider guide has a stopper for temporarily fixing the slider at a position for measurement. It is a characteristic step measuring instrument.

In the present invention, the slider guide has a main scale along its axial direction. The slider guide has the above bracket. The bracket has a reference surface for abutting a reference object (such as the pillar of the door). The slider has a measurement reference line (zero point) and a vernier scale, and is slidably inserted in the slider guide. The slider has a contactor for contacting the object to be measured and a head for axially pushing the slider.

A coil spring for pushing the slider back toward the head is provided between the head and the slider guide. In addition, a stopper is provided between the slider guide and the slider to prevent the slider from rotating and to fix the position of the slider after the contactor is brought into contact with the object to be measured during measurement (implementation). See example).

[Action]

When measuring the step difference with the step difference measuring device of the present invention, the reference surface of the bracket is placed on the surface of the reference object,
Then, the slider is pushed to bring the contact surface of the contactor into contact with the surface of one of the objects to be measured.

Then, the step distance is read from the main scale graduation provided on the slider guide and the measurement reference line and vernier scale provided on the slider. At this time, the reading of the slider scale is performed through the transparent slider guide. Therefore, this reading does not need to be performed by lifting the caliper from the measured portion each time it is measured, unlike the conventional caliper, and can be performed in the contact state.

[Effect] As described above, according to the present invention, it is possible to immediately measure the step difference distance while the step difference measuring device is kept in contact between the reference object and the object to be measured. Therefore, the measurement can be performed in a short time.

Moreover, since the slider guide is transparent, the scale of the slider can be read in a wide angle range, which facilitates measurement.

The coil spring is interposed between the head of the slider and the slider guide. Therefore, if the pushing force of the head is released after reading the scale, the slider immediately returns to its original position by the biasing force of the coil spring. Therefore,
It can be measured continuously. Further, since the stopper is provided on the slider guide, the slider can be temporarily held at the measured scale position. Therefore, it is possible to read the main scale and vernier scale by lifting the step measuring instrument.

Therefore, according to the present invention, a wide angle range (about 270
It is possible to provide a step difference measuring device capable of reading the scale in the degree) and with the measuring device being applied to the object to be measured.

Further, as shown in FIG. 2, the shaft groove 20 of the slider 2 is provided with a stopper groove 201 along its axial direction. On the other hand, a stopper 16 is screwed onto the side pillar 11 of the slider guide, and a tip portion 161 of the stopper 16 is disposed so as to be able to contact the stopper groove 201.

Next, the function and effect will be described.

Here, the case of measuring a step difference in the door portion of an automobile will be described as an example.

That is, this measurement is performed on the surface 9 of the reference object 90 which is a pillar of the vehicle body.
The step distance G between 1 and the surface 81 of the door frame 80 is measured.

In the measurement, the reference surface 151 of the bracket 15 provided on the slider guide is placed on the reference surface 91 of the reference object 90. At this time, the reference surface 151 of the bracket 15 and the contact surface 221 of the contact of the slider are on the same plane, and the zero point is adjusted. This adjustment is performed by rotating the adjusting screw 23 in advance and moving the contact 22 up and down.

Next, the head portion 21 of the slider 20 is pushed against the biasing force of the coil spring 18 to bring the contact surface 221 of the contactor into contact with the surface 81 of the door frame. Then, in this state, the main scale graduation of the slider guide 10 and the vernier scale graduation on the slider 2 are read and the step difference distance is measured.

At this time, as shown in FIG. 2, if the stopper 16 is screwed in and the tip portion 161 thereof is brought into contact with the stopper groove 201 of the slider 2, the slider 2 will move.
It is fixed at 0. Therefore, it is possible to read the main scale and vernier scale by holding the step measuring instrument.

As described above, in the step difference measuring device of this example, the slider guide 10 which is the main scale is a transparent tubular body, and the slider 2 of the vernier scale is configured to slide therein, so that it contacts the bracket 15. Both scales can be read while the child 22 is kept in contact with both the reference object 90 and both surfaces of the door frame 8.

Further, since the slider guide is transparent, the scale of the slider can be read in a wide angle range (about 270 degrees). Therefore, the measurement time is short and the measurement is easy.

Further, since the step difference measuring device of this example has the coil spring 18, if the head portion 21 of the slider is pushed at the time of measurement and the pushing force of the head is released after reading the scale, the slider is immediately returned by the coil spring 18. Therefore, the measurement can be performed continuously.
