Abstract

PURPOSE: To obtain a pin gage which does not receive the resistance of air inside a blind hole when the pin gage is inserted into the blind hole by forming an air vent passage which communicatees from the tip to the rear end on the side inserting into the hole. CONSTITUTION: A through hole 2 as air vent passage is formed on the same axis as a pin gage 1 from one edge up to the other edge. Then, in a state that the pin gage 1 is inserted into a measuring hole 3 up to a halfway part, the measuring hole 3 is in a closed state, and no gap exists. When the pin gage is inserted from the state further, when the pin gage does not have a through hole, the air inside the measuring hole 3 can not find its escape, the air which has been compressed resists against the insertion, and it is difficult to insert the pin gage up to the inner part of the hole. On the other hand, when the pin gage is inserted further from the state, the air at the inside of the measuring hole 3 escapes to the outside through the through hole 2, and it is possible to easily insert the pin gage up to the inner part of the hole. Consequently, a measurement can be performed without a misconception in every measurement.

Description of the Related Art A pin gauge is often used as a measuring instrument for highly accurately measuring a hole drilled by a machine tool or the like because of its simple measurement. A pin gauge is a rod of a cylinder that is itself processed with high precision, and the outer diameter of the cylinder is available in units of 0.01 mm, for example.
It is usually sold as a set of several tens. Measuring with a pin gauge is extremely easy, and by directly inserting a pin gauge of an appropriate size that seems to fit the holes to be measured, you can measure the diameter and depth of the holes and also measure the distance between the holes. When measuring with a caliper or the like, it is also possible to insert a pin gauge that fits into each of the holes and use this as a jig for measurement.

定に支障を来していた。However, since the conventional pin gauge is a solid bar, if the hole to be measured is not a through hole but a so-called blind hole, a pin gauge matching the hole diameter is inserted. Since there is no escape place for the air inside the hole and the air is compressed and resists the insertion of the pin gauge, the pin gauge cannot be inserted deep into the hole, which hinders the measurement.

目的とする。The present invention has been made in view of the above problems, and an object of the present invention is to provide a pin gauge that does not receive resistance due to air inside the blind hole when it is inserted into the blind hole.

A pin gauge is provided, which is provided with an air vent passage. Here, the rear end is the side end that is not inserted and refers to the entire part that is not buried in the insertion hole, and the passage is the air movement passage that is provided from the tip to the rear end of the pin gauge, In addition to the holes, it is meant to include the groove provided on the side surface of the pin gauge.

空気がピンゲージの挿入に抵抗しない。The pin gauge of the present invention is inserted into the blind hole to be measured. At this time, since the air inside the hole escapes to the outside through the air vent passage inside the pin gauge, the air inside the hole does not resist insertion of the pin gauge.

になる。FIG. 1 is a perspective view of a pin gauge according to the present invention. The pin gauge 1 of the present invention is the same as the conventional pin gauge in terms of outer shape and material, but has a through hole 2 as an air vent passage coaxially from the one end face to the other end face of the pin gauge. However, there is a feature. The through hole 2 is the pin gauge 1 as shown.
In addition to the form of being provided in a straight line on the axis of, the hole may be bent in the middle and provided so as to penetrate toward the side surface. Next, comparing with the conventional example of FIG.
A method of using the pin gauge of the present invention in (b) will be described. 2A and 2B show a state in which the pin gauge 1 is partially inserted into the measurement hole 3.
In this embodiment, the outer diameter of the pin gauge 1 cannot be said to exactly match the measurement hole 3, but since the size is close to this, the pin gauge 1 and the measurement hole 3 are in close contact with each other, and the gap is Absent. Then, FIG. 2A which is a conventional example.
In (2), if the air is inserted from this state as it is, the air inside the measurement hole 3 loses its escape and is compressed as it is inserted. Since the compressed air resists the insertion of the pin gauge 1, it becomes difficult to insert the pin gauge 1 deep into the hole.

しまい正確な測定が行えない場合がある。Usually, when measuring the hole diameter, it is judged whether or not the pin gauge matches the hole while confirming the feeling of insertion of the pin gauge with the feeling of a fingertip. If it cannot be inserted, even if the diameter of the pin gauge actually fits into the hole, the operator may mistakenly recognize that the diameter of the pin gauge is larger than the hole, and accurate measurement may not be possible.

ことができる。On the other hand, in FIG. 2 (b) which is an example of the pin gauge according to the present invention, when the pin gauge is further inserted from the state shown in FIG.
Since the air inside the measurement hole 3 passes through the through hole 2 and escapes to the outside, the pin gauge 1 can be easily inserted into the hole. Therefore, in each measurement, the measurement can be performed without misunderstanding.
