Abstract

In the present invention, in the assembly of bolts and nuts, which are widely used for fastening in the industry, a type of holding a bolt head and turning a nut during fastening is common. However, in work alone, one hand holds the bolt head using a spanner and the other hand is not easy to assemble the nut, and in many cases it is inconvenient for space reasons. It relates to a method of making the shape of the end of the bolt to complete the assembly work at the end of the bolt by machining.

To this end, for example, a representative shape is to be concave or convex in a hexagonal shape, that is, to dig a groove such as a hexagon socket head set screw at the end of the bolt or to make a hexagonal protrusion to turn the bolt end and nut to enter only the ready state for assembly. Hold the nut with a spanner and secure it by inserting a hexagon wrench into the hexagon socket head groove that is machined at the end of the bolt using a hexagon wrench or a dedicated box socket. The bolts can be tightened to ensure fast and usable assembly of bolts and nuts, and can also be assembled using commercially available power tools. Faster assembly is possible when using special tools.

Description

The method of making blot, Nut assemble not only clamp bolt head, but also clamp end of screw side of the bolt}

It can be applied to all fields of fastening bolts and nuts, and can be easily tightened even where only bolts are assembled, even where the fastening force is not required.

For example, if a hexagon socket head groove is made at the end of the bolt thread part in the same standard as the hexagon socket head set screw in KS standard, it can be commercialized without using a separate tool. .

First, when assembling the bolt and the nut, use the tool at the end of the bolt to finish the assembly without holding the bolt head. Second, allow two people to complete the assembly work by themselves, except when it is absolutely necessary. By tightening the bolt nut on one side, it guarantees convenience to the worker and speeds up the assembly work.

If the hexagonal grooves are machined at the end of the bolt with the same specifications as the most commonly used hexagonal screws of KS standard (Fig. 1), use the tools commonly used (spanner, hexagonal wrench). As shown in Fig. 2, it can be realized immediately. First, assembling the nut on the opposite side of the groove by using the hexagon socket head set screw, make it like a bolt shape, and then assure the reliability through the simple test of assembling the nut by the proposed method. When the assembly work using the tool can be assembled more conveniently and quickly and the dedicated tool is shown in FIG.

When the bolt and nut are fastened, only the screw thread end of the bolt eliminates the inconvenience of holding the bolt head and turning the nut, and the assembly work is performed at the screw end of the bolt, that is, the nut side. It is possible to assemble even if there is an obstacle that can not be handled by one person between the nuts you want to use, and when there is an obstacle that can be handled by one person, it can provide a convenience to the worker to reduce the fatigue and quick assembly work when using a power tool. can do.

Standardization is required to implement the shape of the hole or protrusion (eg hexagon, square, etc.) of the polyhedron at the end of the bolt thread part, and the bolt end is manufactured by the name already defined by KS standard. The tool inserted into the manufactured shape of the bolt end (hex, square, etc. of the polyhedron) (hex wrench, hexagonal box socket, etc.) may not be a magnetic material, but it is made of magnetic material for the convenience of assembly work. When inserted into the hole or projection of the to maintain the insertion state. After one or more bolts and nuts are pinched, insert the tool in the bolted request and turn the nut to turn the nut, or hold the nut and turn the bolt to tighten it, and then hold the nut inserted in the bolt for final tightening prevention. The tightening operation is terminated by rotating the spanner equipped with. The magnetized tool can hold the nut to some extent, and the assembly process proceeds smoothly by pulling and turning the wrench or the vox socket. As shown in Fig. 4, the bolt tip has the same size as that of the KS standard and is not in the KS standard.

It is industrially available and is not listed.

1 is a view showing the shape of the bolt with a hexagon (square) groove (protrusion) of the threaded end polyhedron of the bolt.

Figure 2 is a diagram showing that the commonly used hexagonal grooves can be assembled using a wrench and a hexagon wrench.

3 is a view showing a process of assembling using a dedicated tool.

Figure 4 shows the specifications of the hexagon socket head cap bolts with bolted ends of bolts, and is a standard table for standardizing those without the hexagon socket head set screws in KS standards.
