な精密な測定を行なう場合に有効である。[Detailed description of the invention] (Technical field) This invention relates to a thickness measuring device that measures the thickness of various plate-like objects at a plurality of measurement points on the plate-like object.
This is effective when performing precise measurements where errors caused by changing the measurement point are undesirable.

止している。(Background Art) An example of a plate-like object whose thickness is to be measured is a cylinder head gasket as shown in FIGS. 1 and 2. This cylinder head gasket 1
There are circular bore holes 2, 2 that match the opening shape of the top of the cylinder, and small circular holes 3, into which bolts for fixing the cylinder head to the cylinder block are inserted.
3. Through holes 4, 4 are bored through which cooling water and lubricating oil can pass. Reference numeral 5 denotes a grommet made of a thin metal plate attached to the inner peripheral edge of each bore hole 2, 2, and this grommet 5 is attached to each bore hole 2, 2 as shown in FIG.
The cylinder head gasket 1 is attached to the peripheral edge of the cylinder block 2, and the thickness of the cylinder head gasket 1 at this peripheral edge is slightly larger than the other parts, and the cylinder head gasket 1 is installed between the upper surface of the cylinder block and the lower surface of the cylinder head. When the grommet 5 is strongly pressed, the pressing force on the peripheral edge of each bore hole 2, 2 provided with such a grommet 5 is particularly large. That is, by particularly increasing the pressing force on the peripheral edges of the bore holes 2, 2, leakage of the high pressure fuel gas generated within the cylinder to the outside is effectively prevented.

ならない。 By the way, the sheet material 7 of such a cylinder head gasket uses an iron plate 6 with a hook or a wire mesh as a core material, as partially shown in FIG.
A compound containing graphite or asbestos as a main component is applied to both the front and back sides of this core material, but in order to maintain good airtightness and liquidtightness between the bottom surface of the cylinder head and the top surface of the cylinder block, ,
The thickness of this sheet material 7 must be uniform over the entire surface. In addition, the thickness of the grommet attachment part, which requires particularly high airtightness, is
must be strictly equal over the entire surface.

も不同となる。 However, the thickness of such a sheet material 7 becomes uneven due to poor surface precision of the roll for forming the sheet material, or due to inclination of the shaft for attaching the roll.
Also, the thickness of the grommet attachment part is 7
Inconsistency occurs not only when the thickness of the grommet is uneven, but also because the pressing surface of the press die for grommet crimping has poor precision.

うにしている。 Therefore, in order to provide a cylinder head gasket with good performance, the thickness is measured at multiple measurement points on the completed cylinder head gasket, and if the thickness is uneven, The cause must be immediately removed. Therefore, conventionally, the thickness of the cylinder head gasket 1 was measured at a plurality of measurement points using a measuring device as shown in FIG. That is, in this conventional device, a lower table 10 placed on rails 9, 9 provided on the upper surface of a base 8 is movable in the direction of arrow a by a motor 11, and is placed on the upper surface of this lower table 10. The upper table 12 is movable by a motor 13 in the direction of arrow b perpendicular to the direction of movement of the lower table 10. A flat sample receiver 14 is placed on the upper surface of the upper table 12. Further, a comparator 16 is attached to the top plate 15 provided above the sample receiver 14.
A measurement terminal 17 protrudes from the lower surface of the upper table 12. The upper table 12 is provided above the base 8 by a frame (not shown) fixed parallel to the upper surface of the base 8 or movable up and down. 17 can be moved up and down slightly by a drive device such as a solenoid with respect to the top plate 15 (even if the entire comparator 16 is moved up and down by a certain amount, or only the measurement terminal 17 is expanded and contracted by a certain amount) ), and by providing it so that it can be held freely at both the upper and lower end positions, the amount by which the measurement terminal 17 protrudes from the lower surface of the top plate 15 can be adjusted.

に行なうことができる。 To measure the thickness of a plate-shaped sample at a plurality of measurement points using such a conventional thickness measuring device, the following procedure is performed. That is, first, the top plate 15
is moved to an appropriate height position and then fixed (if the top plate 15 can move up and down), and when the comparator 16 is lowered (if the entire comparator 16 moves up and down), the measuring terminal 1 of this comparator 16
The lower end surface of 7 can come into contact with the upper surface of the sample holder 14, but
When the comparator 16 rises, the measurement terminal 1
Make sure that the lower end surface of 7 is sufficiently separated from the upper surface of the sample holder 14 (at least the thickness of the sample placed on the sample holder 14). After determining the position of the top plate 15 and fixing the top plate 15 in this way, a plate-shaped sample 18 such as a cylinder head gasket is placed on the top surface of the sample receiver 14 with the measurement terminal 17 raised. , measurement terminal 1
7 is lowered to bring the lower end surface of the measurement terminal 17 into elastic contact with the upper surface of the sample 18. At this time, the comparator 16
The difference between the value indicated by and the value indicated by the comparator 16 when the lower end surface of the measurement terminal 17 comes into elastic contact with the upper surface of the sample receiver before the sample is placed is determined as the thickness of the sample 18. When changing the point at which the thickness of the sample 18 is measured, the measurement terminal 17 is raised and the lower end surface of the measurement terminal 17 is separated from the upper surface of the sample 18.
13 is energized, the upper and lower tables 1
After horizontally moving at least one of 0 and 12 by an appropriate amount and stopping, the measuring terminal 17 is lowered and the thickness of the sample 18 is measured at a different measuring point from the above case. After repeating these operations to measure the thickness at a plurality of measurement points on the sample 18, the sample 18 is taken out from the top surface of the sample receiver 14 with the measurement terminal 17 raised.
Instead, another sample is placed on the sample receiver 14. When measuring the thickness of a sample at multiple points in this way, the parallel movement of the sample holder 14 by energizing the motors 11 and 13 and the lifting and lowering of the measurement terminal 17 before and after this movement are performed by a sequence circuit or Since this is automatically performed in accordance with a predetermined order by a microcomputer, the operator can automatically measure the thickness of the sample by simply loading and unloading the sample onto the sample receiver 14.

スケツトの厚さ測定を行なう場合、測定点を
100m／ｍ移動させると、厚さ測定値に±10μ程度
の誤差が生じることが避けられなかつた。 However, the conventional thickness measuring device for a plate-shaped object constructed and operated as described above has the following drawbacks. That is, when measuring the thickness, the measurement terminal 17
Sample holder 14 that holds the sample 18 between the lower end surface of
In this case, a flat surface having an area equal to or larger than the area of the sample 18 is required, and this wide area must be made into an accurate horizontal surface, which increases the manufacturing cost of the sample holder 14. Moreover, the manufacturing cost of this sample holder 14 increases. Moreover, since the sample holder 14 is supported on the base 8 via the rails 9, 9, the lower table 10, and the upper table 12 so as to be freely movable in the horizontal direction, when the sample holder 14 is moved horizontally, These members 9, 10, 12 must also be precisely manufactured in order to prevent the height of their upper surfaces from changing. Precisely finishing so many members not only considerably increases the manufacturing cost of the entire device, but also makes it difficult to perform precise measurements because the manufacturing errors of each member tend to accumulate. For example, when measuring the thickness of a cylinder head gasket with a thickness of about 2 to 3 m/m using a conventional thickness measuring device as shown in Fig. 3, the measurement points are
When moving 100 m/m, it was inevitable that an error of about ±10 μ would occur in the thickness measurement value.

後は試料１８の厚さを直接読取ることができる。 First, the sample 18 is placed on the frame-shaped sample holder 14a with the measurement terminal 17 of the comparator 16 raised, and the lower surface of the periphery of the sample 18 is supported.
At this time, the sample receiver 14a may be in either an elevated state or a descended state. Next, the sample receiver 14a
If it is in a raised state, lower it (if it is in a lowered state, leave it as it is), bring a part of the lower surface of the sample 18 into contact with the upper end surface 19a of the receiving block 19, and then lower the measuring terminal 17. A part of the sample 18 is attached to the lower end surface of the measurement terminal 17 and the receiving block 19.
The thickness of this sample 18 is measured by holding it between the upper end surface 19a of the sample 18 and the upper end surface 19a of the sample 18. The measurement value obtained when the lower end surface of the measuring terminal 17 is brought into direct contact with the upper end surface 19a of the receiving block 19 without placing the sample 18 on it is obtained in advance, as in the case of the conventional apparatus. However, when the lower end surface of the measuring terminal and the upper end surface of the receiving block come into direct contact, the comparator 16 (not only a dial gauge as shown in the figure, but also an electric one that detects the amount of displacement of the measuring terminal 17 by a change in capacitance) things, etc.
Various structures are available. ) is 0.
If you make it possible to adjust the zero position, you can simply adjust the zero position before measurement.
Afterwards, the thickness of the sample 18 can be directly read.

ける試料の厚さを測定する。 When the thickness measurement of the sample 18 at one point is completed, the measurement terminal 17 is then raised, and then the sample holder 14a is raised. Since the amount of rise of the measurement terminal 17 is greater than the amount of rise of the sample holder 14a, sample 1
The upper and lower surfaces of 8 do not come into contact with either the lower end surface of the measurement terminal 17 or the upper end surface 19a of the receiving block 19. Therefore, at least one of the motors 11 and 13 is energized to move the sample 18 in parallel, and after the sample 18 has been moved by a predetermined amount, the energization is stopped. Upper and lower tables 12a, 10
There are through holes 21 and 2 in the center between a and the sample receiver 14a.
0 and 22 are formed, so that the receiving block 19 does not collide with the inner peripheral edge of these through holes.
Both the upper and lower tables 12a, 10a can be moved. Next, the sample holder 14a is lowered to bring the lower surface of the sample 18 into contact with the upper end surface 19a of the receiving block 19, and then the measurement terminal 17 is lowered and the sample 1
Another point 8 is held between the upper end surface 19a of the receiving block 19 and the lower end surface of the measurement terminal 17, and the thickness of the sample at this point is measured.

きれば良い。 In the above explanation, in order to measure the thickness of the sample itself, the lower end surface of the measurement terminal 17 is connected to the upper end surface 19a of the receiving block 19 with the sample removed.
However, if you only want to find the difference in thickness at each measurement point, the lower end surface and the upper end surface do not necessarily need to be in direct contact with each other; It is sufficient that the end surface can come into contact with the upper surface of the sample.
