Description

Bolt / Nut Joint / Separation Tool

The present invention relates to a tool for fastening / removing a bolt / nut in a machine part having a plurality of interferences, the handle having a long rod shape and a plurality of bending portions formed on one side to avoid the interference; It is related to the bolt / nut tightening / disassembly tool consisting of a socket is formed on one side is coupled to the end of the operation handle and the opposite side is formed with a functional groove to be engaged with the head of the bolt / nut.

In general, bolts and nuts that can be fastened to each other are widely used as coupling members for joining a plurality of structures in manufacturing and assembling processes of mechanical components including aircraft, ships, and automobiles.

In general, in order to fasten / disassemble the bolt or nut, a fastening tool such as a wrench or a wrench, or a tool such as a puller or a nipper or a plier is used to turn the bolt / nut to turn / unfasten.

However, when using such a conventional tool, when bolts / nuts are to be fastened / dismantled in a complicated machine structure in which various parts are scattered, sufficient work space cannot be secured due to the interference of other parts. An impossible problem arises.

In particular, since there are many such complex mechanical structures in a comprehensive machine production process such as the above-mentioned aircraft, in order to fasten / dismantle bolts / nuts as a conventional tool, parts that cause interference in the work space are temporarily removed and removed. It is true that there is an inefficiency in the work that needs to be reinstalled after the fastening / dismounting work.

The present invention was devised to solve these problems, and easily tightens the bolts / nuts even in a narrow place where there is not enough space for performing the bolts / nuts fastening / disassembly or where there is an interference. Its purpose is to provide a bolt / nut tightening / removing tool that enables / dismount.

In order to achieve this object, the present invention provides a tool for fastening / removing bolts / nuts in a machine part having a plurality of interferences, which is formed in a long rod shape and a plurality of bendings to avoid the interferences on one side. The handle is formed of an additional portion, and one side is coupled to the end of the operation handle and the other side is composed of a socket formed with a functional groove that is engaged with the head of the bolt / nut.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention in detail.

First, in adding reference numerals to components of each drawing, the same components are described so as to have the same reference numerals as much as possible even if displayed on different drawings.

1A, 1B and 1C are front, side and plan views, respectively, showing front and side and planar shapes of a bolt / nut fastening / removing tool according to a preferred embodiment of the present invention.

As shown, the bolt / nut fastening / disassembly tool according to a preferred embodiment of the present invention, the socket 100 is inserted into the head of the bolt / nut, and the operation handle for allowing the operator to turn the socket 100 ( 200).

The manipulation handle 200 is formed in a long rod shape and has a plurality of bent portions 210 to 230 to avoid interferences on one side, wherein the bent portions 210 to 230 face the front side as shown in FIG. 1A. The first bent portion 210 bent 45 degrees from the vertical direction to the left, the second bent portion 220 bent 45 degrees more than the first bent portion, and the plane as shown in FIG. 1C. A third bent portion 230 bent 90 degrees downward from the horizontal direction is formed.

In addition, one side of the socket 100 is connected to the end of the operation handle 200, the opposite surface is formed with a functional groove 110 to be engaged with the bolt head or nut to be fastened / disassembled.

Accordingly, the operator inserts the bolt / nut at the corresponding position in the machine part, inserts the head or nut of the bolt into the functional groove 110 of the socket 100, and then uses the operation handle 200 to connect the socket 100. By rotating), it is possible to perform the fastening / disassembly operation.

2A, 2B and 2C are front and side view and top views, respectively, illustrating the front and side and planar shapes of a bolt / nut tightening / removing tool according to another preferred embodiment of the present invention.

As shown, the bolt / nut tightening / disassembly tool according to another embodiment of the present invention, the socket 400 is coupled to the operation handle 300 and the end of the operation handle 300 as in FIG. The operation handle 300 includes a fourth bent portion 310 that is bent 90 degrees from the vertical direction to the right side as shown in FIG. 2A to avoid interferences different from those of FIG. 1, and FIG. 2B. As shown in FIG. 5, the fifth bent portion 320 bent to the right by 30 degrees with respect to the side, and the sixth bent portion 330 which is bent by 30 degrees to the opposite of the fifth bent portion 320 and shown in FIG. 2C. As described above, the seventh bent portion 340, which is bent upward by 60 degrees with respect to the plane, and the eighth bent portion 350, which is bent by 150 degrees, is formed opposite to the seventh bent portion.

Therefore, the operator inserts the bolt / nut at a predetermined position in the machine part, inserts the head or nut of the bolt into the functional groove 410 of the socket 400, and then operates the operation handle as described above with reference to FIG. By using the 300 to turn the socket 400 will be able to perform the fastening / disassembly.

FIG. 3 is a perspective view showing a shape in which the bolt / nut fastening / removing operation is performed at a predetermined position in the machine part 1 by using the bolt / nut fastening / disassembling tool shown in FIGS. 1 and 2. It can be seen that the fastening / disassembly of the bolts / nuts is possible without being affected by the interferences 10 to 30 by the bent portions 210 to 230 and 310 to 350 formed on the handles 200 and 300. Also, since the operation handles 200 and 300 themselves are formed in a long rod shape, it can be seen that the operation is easy even in a narrow place.

As mentioned above, although preferred embodiments of the present invention have been described in detail, those of ordinary skill in the art to which the present invention pertains should realize the present invention without departing from the spirit and scope of the present invention as defined in the appended claims. It will be appreciated that various modifications or changes can be made.

In particular, by configuring the bent portion formed in the operation handle in accordance with the shape of the interference in the mechanical part, it is possible to easily tighten / disassemble the bolt / nut in a complex mechanical part.

In addition, the above embodiment has described a case in which a function groove for inserting a bolt / nut head is formed in a socket that is coupled to the end of the operation handle. However, by combining various conventional wrench sockets selectively with the operation handle, Of course, it is also possible to conveniently perform the bolt / nut tightening / disassembly operation.

Accordingly, modifications to future embodiments of the present invention will not depart from the technology of the present invention.

As described above, according to the present invention, since the operation handle is formed in a long rod shape and has a large number of bent portions therein, a narrow space in which there is not enough space for the fastening / disassembly of the bolt / nut is not provided. Where, even in the presence of interference there is an advantage that can be easily fastened / disassembled bolts / nuts.
