Abstract
Wherein the body is a body (30, 430); Bolt insertion holes (10a, 410a) formed in the body; And a scale (20, 410a) formed on the body in parallel with the bolt insertion hole adjacent to the bolt insertion hole, wherein the bolt (200, 300) can be inserted into the bolt insertion hole, And the length of the bolt is measured by a scale, and the thickness of the bolt can be measured according to the diameter of the insertion hole.
Description
The present invention relates to a device for measuring the thickness and length of a bolt.
A bolt is a mechanical element used to fix building materials or machine parts, usually with a head, which is threaded into a round bar. The shape of the head is usually hexagonal, but there are also squares, cylinders, and saucers. The most widely used is through bolts, bolts in the holes of the bolts, and then tighten with a nut.
Bolts are usually made of steel and are called bolts, semi-finished bolts, black bolts, etc., which are finished according to the fineness of the surface. There are also bolts made of brass or light alloy.
The load applied to the threaded portion of the bolt may be subjected to axial load, torsion, shear load, axial load, or static load.
These bolts are used in various lengths and types in the assembly process of the product and are generally used after being classified according to their length.
Therefore, it is desirable to measure the length and thickness of the mixed bolts, classify them according to length and thickness, and store and manage them. The present invention is intended to easily measure the length of the bolt.
There is an open utility model 2015-0001739 to measure the length of the bolt. However, this is different from the measurement of a stud bolt measuring device, which is different from the measurement of a common bolt having a bolt head as in the present invention.
The present invention aims to easily measure and separate the thickness and length of various bolts.
The present invention provides a
Also, in the present invention, the bolt insertion hole or groove may be formed from the upper surface to the bottom surface of the body.
In the present invention, the bottom surface of the bolt insertion hole may have a
Also, in the present invention, the bolt insertion hole or groove is formed in accordance with the standard of the bolt thickness, and the thickness of the bolt to be inserted can be measured.
Further, in the present invention, when the bolt measuring device is for measuring the length of the plate head bolt, the head of the plate head bolt may be inserted into the bolt insertion hole or the groove, The bolt insertion hole or the end of the groove may be formed so as to stop the head of the bolt.
The present invention has a hole or groove through which a bolt can be inserted into the body and a ruler is engraved on the body so that the bolt can be easily inserted into the hole or groove so that the length of the bolt can be easily measured.

As described above, in the present invention, the bolt insertion hole or groove is formed in the measuring
In the case of the bolt insertion hole, it is preferable that the bolt insertion hole is formed of a transparent material such as acrylic. However, when the bolt insertion hole is formed in the shape of a groove, the bolt insertion hole can be replaced with all materials such as opaque plastic and machinable aluminum.
For reference, bolts are standardized by thickness and length.
The thickness (diameter) is generally 2, 3, 4, 5, 6, 8, 10a, 12, 16, 20mm, and the length is more than the thickness.
For example, bolt M5x10a refers to a bolt with a thickness of 5 mm and a length of 10 am.
This device enables simultaneous measurement of the thickness and length of the bolt.
The diameter of the hole or groove of the device is formed to be slightly larger than the thickness of the bolt, so that the bolt is easily inserted and formed to match the thickness.
For example, a bolt of M5x10a is made slightly larger than 5mm so that bolts with a diameter of 5mm can be inserted easily.
