Description

Thick gauge

The present invention relates to a thickness gauge, and more particularly to a thickness gauge for measuring the thickness of an object.

At present, there are many kinds of measuring tools for measuring the structural dimensions of various electronic or mechanical products, such as block gauges, inner diameter gauges, outer diameter gauges, vernier calipers, thickness gauges, and the like. For the thickness gauge, it has been widely used to measure the size of the gap between the two joint faces of the product because of its high control precision.

Conventional thick gauges include a plurality of measuring bodies of the same shape and an annular body. Each measuring body has a substantially rectangular shape, and a through hole is opened adjacent to one end thereof, and each measuring body is provided with a scale for measuring thickness for judging the size of the gap between the two joint faces of the product to be measured. Each measuring body is sleeved on the annular body by a through hole to form the thickness gauge.

However, the thick gauge of the structure has a large volume, is inconvenient to carry, and has a large number of measuring bodies, so the manufacturing material is increased and the manufacturing cost is increased.

In view of this, it is necessary to provide a thick gauge that is compact in structure, convenient to carry, and low in cost.

A thick gauge comprising a body having a plurality of different thickness measuring portions on the edge of the body, the body having an upper surface, a lower surface and a circumferential surface adjacent to the upper and lower surfaces, the upper surface being adjacent to the upper surface a plurality of grooves are recessed in the circumferential surface, and a portion between the bottom side and the lower surface of each groove forms the measuring portion, and each measuring portion is marked with a corresponding measuring portion thickness The value.

Compared with the prior art, the thick gauge of the present invention is provided with a multi-quantity measuring portion on a body, which reduces the material for manufacturing the thick gauge and reduces the manufacturing cost thereof, and the thick gauge structure is small and convenient to carry.

1 is a perspective view of a thick gauge according to a preferred embodiment of the present invention.

2 is a perspective view showing the gap between two support columns by applying a thickness gauge according to a preferred embodiment of the present invention.

Referring to FIG. 1, the present invention discloses a thickness gauge 10 including a body 12. The body 12 is substantially disk-shaped and is made of a metallic material. The body 12 includes an upper surface 122, a lower surface 124, and a circumferential surface 126 adjacent to the upper surface 122 and the lower surface 124. The upper surface 122 is concavely spaced from the circumferential surface 126 at a plurality of recesses 128, each of which is radially distributed at the edge of the upper surface 122. The groove depth of the groove 128 is sequentially increased to form a different measuring portion 14 between the bottom of each groove 128 and the lower surface 124. The value of the thickness of the measuring portion 14 (not shown) is marked on the bottom of each groove 128 to obtain a measured value.

Referring to Figure 2, a method of measuring a workpiece 20 for measuring the gauge 10 will now be described.

The workpiece 20 includes two support columns 30 and a bottom plate 50. The two supporting columns 30 are respectively protruded from the bottom plate 50, and the two supporting columns 30 are separated by a small gap. By rotating the body 12 of the gauge 10, the measuring portion 14 which is close to the gap between the two supporting columns 30 can be sequentially inserted between the two supporting columns 30 to select and fit into the gap. The measuring portion 14 corresponds to the gap between the two supporting columns 30 corresponding to the scale on the groove 128 of the measuring portion 14, thereby obtaining the distance between the two supporting columns 30.

The thickness gauge 10 of the present invention is provided with a plurality of measuring portions 14 on a body 12, which reduces the material for manufacturing the thickness gauge 10 and reduces the manufacturing cost thereof, and the thick gauge 10 has a compact structure and is convenient to carry.

It can be understood that the shape of the gauge 10 is not limited to a circular shape, and may be other shapes.

It can be understood that the gauge 10 can also be made of a plastic material.

It can be understood that the upper surface 122 of the gauge 10 protrudes from the circumferential surface 126 with equally spaced protrusions, so that different portions of the protrusion between the top end and the lower surface 124 form different measuring portions.

It can be understood that the spacing angle between each of the grooves 128 or the protrusions may be different.

It can be understood that the groove depth of the groove 128 may not be arranged in order of increasing order.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
