Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention [Industrial Application Field] The present invention relates to a film thickness measuring gauge for measuring the film thickness of paint or the like before drying.

[Conventional technology]

Conventionally, as shown in FIGS. 7 and 8, this type of film thickness measuring gauge has a thin plate-like gauge body 41.
By cutting out the lower side of the
, and a plurality of measurement protrusions 44 to 43 having different protrusion lengths between both reference protrusions 42 and 43.
Reference planes 42a, 43 are provided with reference protrusions 47, and the protruding end surfaces of the reference protrusions 42, 43 are brought into contact with the surface of the object W to be painted.
a, and the protruding end surfaces of the measuring protrusions 44 to 47 are measurement surfaces 44a to 47a for measuring the film thickness of the paint P applied onto the object W to be coated (Utility Model No. 53). -Refer to No. 58560). At the time of measurement, as shown in FIG. 8, the gauge body 41 is held perpendicular to the object W to be painted, and the measuring surfaces 44a to 47a are pressed against the surface of the coating W. Thereafter, the film thickness of the paint P was measured by reading a scale (not shown) marked on the last measurement surface 44a to 47a to which the paint P was attached.

[Problem that the invention seeks to solve]

However, with this configuration, since the thickness of the gauge body 41 is thin, it is difficult to apply the gauge body 41 perpendicularly to the surface of the object W to be coated during measurement. There were times when measurements were taken, which caused measurement errors. Furthermore, since the measurement work is done manually, the contact angle and contact force vary depending on the operator, resulting in measurement errors. Furthermore, when the object W to be painted is made of an elastic body such as rubber, the reference protrusions 42 at both ends,
43 was strongly pressed against the surface of the object W to be painted, the central part of the object W to be painted swelled, which also caused measurement errors.

Structure of the Invention [Means for Solving the Problems] Therefore, in view of the above problems, the present invention includes an insertion portion inside and a leg portion placed on the lower side at right angles to the surface of the object to be coated. a substantially square cylindrical gauge holder, a plate-shaped gauge body that is temporarily held and installed in the insertion part of the gauge holder and can fall under its own weight while being guided by the side wall of the insertion part; holding means temporarily held by the gauge holder at a predetermined distance from the lower end surface of the gauge body; The gauge holder has a plurality of measuring surfaces, each having a different depth from the surface, for measuring the film thickness of the paint, etc. on the object to be painted, and a part of the holding means such as an insertion hole. With the legs placed on the surface of the object to be painted, the temporary holding of the holding means is released, the gauge body is allowed to fall under its own weight, and the reference plane is kept perpendicular to the surface of the object to be painted. A configuration is adopted in which contact is made from a certain distance with a certain pressing force. Therefore, whoever makes the measurement can easily apply the measuring surface perpendicularly to the measuring surface, and the measuring surface of the gauge body can be brought into contact with the measuring surface of the gauge body at any time from a fixed distance with a fixed pressing force. In addition, we have provided many reference planes and placed measurement planes between them, so even if the object to be coated is warped, the
The amount of deflection can be reduced and accurate measurements can be made.

[Function] In the present invention, the measurement surface of the gauge device body is guided by the side wall of the insertion part of the gauge holder and brought into contact with the surface to be measured of the object to be coated by falling due to its own weight. It can be applied at right angles, and since the reference surface of the gauge body is always brought into contact with the surface of the object to be coated with a constant pressing force from a certain distance, the object to be coated will not bend, and the object to be measured will not bend. The surface can be measured in a stable state within a narrow range, making accurate measurements possible.

〔Example〕

Hereinafter, one embodiment embodying this invention will be described in the first to third embodiments.
This will be explained according to Figure 3.

The film thickness measuring gauge of this embodiment mainly includes a gauge body 1 and a gauge holder 2 that holds the gauge body 1.
It is composed of.

A plurality of reference protrusions 3, 4, 5, 6, 7, and 8 are formed protruding from the lower end of the plate-shaped gauge body 1 at equal intervals and having the same width as the gauge body 1.
Those protruding end surfaces are reference surfaces 3a, 4a, 5a, 6a, 7a, which come into contact with the surface of the object W to be coated during measurement.
It is marked 8a. In addition, the reference protrusions 3, 4, 5,
The protrusion amounts of 6, 7, and 8 are all the same length.

Further, in the central part between the reference protrusions 3 to 8, there are a plurality of measurement protrusions having the same width as the gauge body 1 and having different protruding lengths along the longitudinal direction of the gauge body 1. Parts 11, 12, 13, 14, 1
5 is formed protrudingly. Each measurement protrusion 11 to 15
The protruding end surfaces are measurement surfaces 11a, 12a, 13a, 14a, 1 for measuring the film thickness of paint P, respectively.
5a. That is, this measurement surface 11a
15a have different depths from the reference planes 3a to 8a. And the reference plane 3a~
When measuring the film thickness by bringing 8a into contact with the surface of the object W to be painted, each measurement surface 11a to 1 is measured according to the film thickness of the paint P.
The paint P is attached to the parts 5a in order from the one with the longest protrusion length. Although not shown, from each measurement surface 11a to 15a to reference surface 3a to 8.
Until a = Scales corresponding to the dimensions are written on both sides of the gauge body 1, and during the measurement, by reading the scale corresponding to the last measurement surface attached to the paint P, the paint P can be measured. It is now possible to measure film thickness.

An insertion hole 16, which is a part of the holding means, is transparently provided in the central part of the side surface of the gauge body 1 in the thickness direction.

Leg portions 19 having the same width as the gauge holder 2 are formed protruding from both lower ends of the gauge holder 2 having a substantially rectangular cylindrical shape. An insertion portion 18 through which the gauge body 1 can be inserted is formed inside the gauge holder 2 so as to face in the vertical direction of the gauge holder 2.
Further, the insertion portion 18 is formed so that when the gauge holder 2 is placed on the object W to be painted during film thickness measurement, the side wall 18a of the insertion portion 18 is perpendicular to the object W to be painted.

In the center of the side wall of the gauge holder 2, an insertion hole 20, which is a part of the holding means, is provided through the opposite side wall. The insertion hole 16 of the gauge body 1 inserted into the insertion portion 18 and the insertion hole 2
0 and inserting the dowel pins 21, which are part of the holding means, into these insertion holes 16 and 20, the gauge body 1 is inserted into the gauge holder 2.
It is now possible to hold it inside. Therefore, in this embodiment, the insertion holes 16, 20 and the knock pin 21 constitute a holding means. At this time, the reference surface 3 of the lower end of the inserted gauge body 1
a to 8a and the lower surface of the leg portion 19 of the gauge holder 2 are temporarily held apart from each other by a certain distance. Therefore, by removing the dowel pin 21, the gauge body 1 will fall under its own weight.
Note that the holding means is not limited to the above, and any structure may be used as long as it temporarily holds the gauge body 1 on the gauge holder 2.

Next, using this film thickness measuring gauge,
When measuring the film thickness of paint P applied on top,
This will be explained according to FIGS. 4, 5, and 6.

First, the gauge body 1 is inserted into the insertion portion 18 of the gauge holder 2, and the
It is temporarily held at a predetermined height position within the gauge holder 2. Next, the measurement gauge is placed perpendicularly to the surface of the object W to be painted, and the dowel pin 21 is removed to release the temporary holding of the holding means, and the gauge body 1 is placed on the paint P of the object W to be painted. Let it fall under its own weight. Then, the gauge main body 1 is guided by the side wall 18a of the insertion portion 18 and falls under its own weight, and the reference surfaces 3a to 8a abut perpendicularly to the surface of the object W to be coated. At this time, the plurality of reference surfaces 3a to 8a come into contact with the paint P of the object W to be painted before the measurement surfaces 11a to 15a, and as shown in FIG. (indicated by the wavy line) to make a smooth surface. Then, by reading the scale corresponding to the last measurement surface to which the paint P has adhered, the film thickness of the paint P can be measured.

Therefore, according to this embodiment, the width of the leg portion 19 is formed to be the same as the width of the gauge holder 2, thereby making it wider than the width of the gauge body 1. 8a directly and manually against the surface of the object W to be painted at right angles, it is easier to bring the reference surfaces 3a to 8a of the gauge body 1 into contact with the surface of the object W to be painted at right angles, Moreover, there is no pressure difference on the gauge body 1 due to the weight of the gauge body 1, making accurate measurement possible.

Additionally, measurement surfaces 11a to 11a are provided between each reference surface 3a to 8a.
15a, it is possible to suppress minute irregularities on the object W to be coated and measure it as a smooth surface, thereby minimizing measurement errors.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and, for example, it is also possible to do as follows.

(1) The measurement surfaces 11a to 15a are not included in this embodiment,
The width of the measurement surfaces 11a to 15a may be shorter than the width of the gauge body 1. In this way, when the gauge holder 2 is tilted, different measurement surfaces can be prevented from coming into contact with the paint.

(2) In addition to this embodiment, the gauge holder 2 may have a shape having two or more gauge insertion portions 18. In this way, the thickness of two or more different parts can be measured simultaneously with one gauge holder, and the width of the legs becomes wider.
It becomes easier to arrange the paint P on the object W at right angles.

〔Effect of the invention〕

As detailed above, in this invention, it is possible to easily bring the reference surface and measurement surface of the gauge body into contact with the paint on the object to be painted at right angles, and to apply constant pressure from a constant distance. Since the reference surface can be brought into contact with the surface of the object to be coated, measurement errors caused by the measurer can be eliminated, and the measurement accuracy can be improved, which is an excellent effect.
