Description

The present invention relates to a measuring tool capable of measuring the height of a component mounted on a base.

For example, calipers (see, for example, Patent Document 1), micrometer, and the like have been conventionally known as measuring instruments that are operated by the hands of an operator to measure the height, width, and the like of parts. When measuring the external dimensions of a block-shaped part that is a component of a processing device or the like, the part is sandwiched between U-shaped parts called caliper jaws and formed into a caliper's main scale. The operator reads the main scale and measures it.

However, if the height of the block-shaped part is attached to the base of the processing apparatus and the height of the part is to be measured, the part cannot be properly pinched by the caliper jaw. In preparation for such a case, a depth bar that can be expanded and contracted in the longitudinal direction of the caliper is provided on the lower end side of the caliper. Then, the tip of the depth bar is brought into contact with the base, the tip surface of the depth bar is used as the reference surface, and the end of the main scale is brought into contact with the upper surface of the part, so that the length of the depth bar protruding from the caliper is measured to measure the length of the part. The height can be measured.

It is sectional drawing when the height of the part placed on the base is measured by the measuring tool, and is seen from the front.

The measuring tool 1 shown in FIG. 1 is a measuring tool for measuring the height of a component placed or placed on a base, and includes a straightedge body 10 having a scale of 10 g and a longitudinal direction (Y-axis direction) of the straightedge body 10. ) Is provided with a slider 12 slidably combined with the straightedge body 10. The straightedge body 10 is formed of, for example, a synthetic resin or metal in a long shape, and is formed on the surface 10a along the longitudinal direction with the end edge of one end 10c on the −Y direction side as a reference (0 mm). A scale of 10 g is formed in units of 1 mm, and numerical values are described as 10, 20, and ~ 100 for each 10 mm. The shape of the straightedge body 10 and the formation position of 10 g of the scale are not limited to this embodiment. For example, from one end 10c of the straightedge body 10 to be perpendicular to the longitudinal direction of the straightedge body 10. It may be a curved scale in which another straightedge body extending in the intersecting X direction is integrally formed.

The slider 12 is, for example, a plate whose outer shape is rectangular in a plan view, and is made of a transparent member such as polycarbonate. The material for forming the slider 12 is not limited to the transparent member. For example, the slider 12 includes a flat plate-shaped central portion 12d, and through hole forming portions 12c and 12e standing vertically in the + Z direction are integrally formed at both ends of the central portion 12d in the longitudinal direction (Y-axis direction). It is formed. From the upper part of the through hole forming portion 12c, an end portion 12f extending in parallel with the central portion 12d is formed toward the −Y direction side, and from the upper part of the through hole forming portion 12e, the center toward the + Y direction side. An end portion 12h extending parallel to the portion 12d is formed. For example, the central portion 12d of the back surface 12b of the slider 12 or the ends 12f and 12h of the front surface Wa of the slider 12 are made of a base resin or a rubber resin in which fine particles are kneaded, and are slipped to impart frictional resistance. A stop sticker may be attached.

As shown in FIGS. 1 and 2, the slider 12 is formed with a first through hole 121 (not shown in FIG. 1) and a second through hole 122 that penetrate the front surface 12a and the back surface 12b of the slider 12. There is. For example, the first through hole 121 and the second through hole 122 are formed through the through hole forming portions 12c and 12e of the slider 12 so as to face each other in the Y-axis direction. The lateral width (length in the X-axis direction) of the first through-hole 121 and the second through-hole 122 is formed to be slightly larger than the lateral width (length in the X-axis direction) of the straightedge body 10. The height (length in the Z-axis direction) of the through hole 121 of 1 and the second through hole 122 is formed to be slightly larger than the thickness of the straightedge body 10.
The slider 12 is moved in contact with the straightedge body 10 and does not slide off the straightedge body 10. For example, when the first through hole 121 and the second through hole 122 have the same shape, the first through hole 121 and the second through hole can be arranged by shifting the positions in the Z direction. The first through hole 121 of the scale body 10 is brought into contact with the front surface 10a, and the second through hole 122 is brought into contact with the back surface 10b. Further, for example, the slider 12 is curved in the X direction, and the first through hole 121 and the second through hole 122 are curved so as to match the shape, so that the first through hole 121 and the second through hole 122 are formed. It may be brought into contact with the surfaces 10a and 10b. Further, the magnet 123 may be embedded in, for example, the central portion 12d of the slider 12, and the slider 12 may be attracted to the straightedge body 10 by the magnetic force of the magnet 123 so that the slider 12 does not slide off the straightedge body 10. ..

The horizontal width (length in the X-axis direction) of the slider 12 is formed to be larger than the horizontal width (length in the X-axis direction) of the straightedge body 10, and the slide 12 is combined with the straightedge body 10 so as to be slidable. In this case, the outer portion of the slider 12 on the X direction side protrudes from both sides of the straightedge body 10. Then, in the outer region of the surface 12a of the slider 12 on the + X direction side, an auxiliary scale with respect to the scale 10 g of the straightedge body 10, that is, a vernier scale 12 g for further subdividing and accurately reading the scale of the straightedge body 10 is provided. It is formed. The vernier scale 12g has, for example, scales formed at intervals of 9/10 or 19/20 along the longitudinal direction with the end edge of the end portion 12f of the slider 12 as a reference (0), and 1, 2, 3, And 4 and the numerical value are attached.

As shown in FIG. 2, the straightedge body 10 is penetrated from the back surface 12b to the front surface 12a in the first through hole 121 of the slider 12, and the straightedge body 10 is penetrated from the front surface 12a to the back surface 12b in the second through hole 122. The slide 12 can be slidably combined with the straightedge body 10 by penetrating toward. That is, the user of the measuring tool 1 brings the finger F into contact with the end portion 12h of the slide 12 combined with the straightedge body 10 and applies a force to the slide 12 in the + Y direction, whereby the slide 12 Slides in the + Y direction relative to the straightedge body 10.

The operation of the measuring tool 1 when measuring the height of the component P mounted on the base B shown in FIG. 3 by using the measuring tool 1 shown in FIG. 3 will be described below. The base B shown in FIG. 3 is, for example, a device base for a grinding device, a cutting device, or the like, and its upper surface Ba is a flat horizontal surface. The part P is a component of a grinding device or a cutting device, and for example, the outer shape is formed in a rectangular parallelepiped block shape.

First, the user brings one end 10c of the straightedge body 10 of the measuring tool 1 into contact with the upper surface Ba of the base B, causes the straightedge body 10 to stand on the upper surface Ba of the base B, and at the same time, the straightedge body 10 The side surface 10e is brought into contact with the side surface Pd of the component P. Next, for example, the slider 12 is slid and moved in the extending direction of the straightedge body 10, that is, in the −Z direction, so that the lower side of the slider 12, that is, the end side of the end portion 12f is brought into contact with the upper surface Pa of the component P.

Next, the user reads the scale 10 g of the straightedge body 10 indicated by the end edge of the end portion 12f. Since the slider 12 is made of a transparent member, the user can read the scale 10 g of the straightedge body 10 through the end portion 12f of the slider 12. In FIG. 3, the end edge of the end portion 12f of the slider 12 is located between 26 mm and 27 mm of the scale 10 g of the straightedge body 10. Therefore, in order to measure the height of the component P in units of 0.1 mm, the user further reads the vernier scale 12 g formed on the slider 12. That is, in FIG. 3, since the vernier scale 12 g of the third scale from the end side (0 scale) of the slider end 12f overlaps the scale 10 g of the straightedge body 10, the reading value of the vernier scale 12 g is 0. It becomes 3 mm. Therefore, the user can measure the height of the component P as 26.3 mm. If the slider 12 is displaced by a predetermined amount (for example, 10 mm) in the direction away from the upper surface Pa of the component P and the vernier scale 12 g is read in that state, the slider 12 may not be formed of the transparent member.

As described above, the measuring tool 1 can accurately measure the height of the component P placed or placed on the base B in units of 0.1 mm, and is inexpensive because it does not have a complicated configuration. Can be manufactured. Further, the measuring tool 1 does not take up a lot of space when stored in the tool box, and is compact and easy to carry.

The measuring tool 1 according to the present invention is not limited to the above embodiment, and the size and shape of each configuration of the measuring tool 1 shown in the attached drawings are not limited to this. It can be appropriately changed within the range in which the effect of the present invention can be exhibited.
