Abstract

The present invention relates to a socket for fastening stud bolts, and the purpose of the socket for fastening stud bolts is that the stud bolt is not structured so that a spanner or impact wrench can be directly used when planting a stud bolt on a pad flange. Insert two hex nuts into the bolt flange by using a spanner or impact wrench to fasten the stud bolts, which requires a lot of work time and eliminates the inefficiency of many stud bolts. In order to improve the productivity by using a socket instead of a hexagon nut.

The structure of the socket for fastening the stud bolt is made as follows.

The outer shape of the socket (5) has a rectangular structure for the use of a spanner, a rectangular groove (8) structure for inserting an impact wrench inside, and the contact area with the stud bolt (3) is round (6). The screw 7 is processed so that the stud bolt 3 can be fastened to the site where the stud bolt 3 is fastened.

Description

Socket for Stud Bolt Fastening {Socket for Stud-Bolt Assemble}

The present invention relates to the fastening of the stud bolts to the pad flange, and more particularly to the stud bolt to plant the cover or machine to be installed on the ship, the stud bolt is planted in the pad flange At the time, it is not designed to use a spanner or impact wrench directly, so conventionally, two hex nuts are inserted into the stud bolt, the upper nut is turned to the right and the other nut is turned to the left. After the hex nut is completely fixed to the stud bolt, the stud bolt is completely fixed by planting and fastening the stud bolt to the pad flange using a spanner or an impact wrench. When the stud bolt is completely fixed to the pad flange as described above, the hex nut, which has been fastened to the stud bolt, is reversed from the above, that is, the upper nut is turned to the left and another lower nut is turned to the right. After removing, the fastening of the stud bolt is completed.

As described above, a number of stud bolts are fastened to a ship. In the related art, the work process is complicated, and a lot of time is required for fastening the stud bolts. Occurred.

The present invention is to improve the fastening of the stud bolts using a socket when fastening the stud bolt to the pad flange in order to solve the conventional problems as described above,

By fastening the stud bolts to the pad flanges using conventional hex nuts, spanners can be used when fastening the stud bolts to the pad flanges to improve the complexity of the work process and the time consuming procedure for fastening the stud bolts. Alternatively, the socket is provided with a stud bolt fastening socket so that the fastening can be easily performed using an impact wrench. When the stud bolt is fastened, the socket is completed to provide a function capable of working in any place.

3 is a conventional stud bolt fastening flow chart,

The socket is provided when the stud bolt is fastened to the pad flange to shorten the working process and the working time, thereby improving productivity and improving the assemblability.

In the socket for fastening stud bolts,

First, the socket 5 is applied to a material having a strength higher than that of the stud bolt 3 so that the strength is maintained, and the design of the socket 5 is sufficiently considered for the wear of the screw part due to repeated fastenings, thereby preventing wear. . When the stud bolt (3) is fastened to the pad flange (1), the outer shape of the socket (5) has a rectangular structure so that a spanner (or impact wrench) can be used, and a spanner is formed inside the upper end of the socket (5). (Or impact wrench) has a square groove (8) structure, the contact area with the stud bolt (3) in the round (6) treatment in order to reduce the coefficient of friction, the stud bolt (3) is fastened The screw 7 is machined so that the stud bolt 3 can be fastened to the part to be fastened to the stud bolt 3.

As described above, the outer shape of the socket 5 has a quadrangular structure so that the socket 5 can be inserted into the spanner (or impact wrench), and the upper side of the socket 5 has a square to fit the spanner (or impact wrench). It has a groove (8) structure. In order to make it easier to remove the socket (5) after fastening the stud bolt (3), the contact area with the stud bolt (3) is rounded (6) to reduce the friction, and the stud bolt (3) ), The assembly of the stud bolts (3) is possible in a short time by processing the screw (7).

In the figure, reference numeral 2 denotes a hexagon nut.

(Conventional Example)

3 is a flow chart illustrating a conventional stud bolt fastening method, in order to fasten the stud bolt to the pad flange, two hex nuts are inserted into the stud bolt, the upper nut is turned to the right, and the other nut is turned to the left. After these two hex nuts are fully secured to the stud bolts, the stud bolts are fully secured by tightening the stud bolts to the pad flanges using a spanner (or impact wrench). After completing the fastening of the stud bolt as described above, the hex nut inserted in the stud bolt is removed. The hex nut is reversed from the above, that is, the upper nut is turned to the left and the other nut is turned to the right. Removing the two hex nuts finishes the work on the pad flange of the stud bolt.

(Example of the present invention)

1 is a flow chart illustrating a stud bolt fastening method of the present invention, the stud bolt is slightly inserted into the pad flange, and the socket as shown in FIG. 2 is inserted into the stud bolt, and then tightened with a spanner (or impact wrench) to tighten the stud bolt. Completely planted in the pad flanges, the socket is removed and the work done on the pad flanges of the stud bolts is completed.

(Variations, applications and legal interpretations)

The present invention is not limited to the specific preferred embodiments described above, anyone of ordinary skill in the art without departing from the spirit of the present invention claimed in the claims various modifications Of course, such changes are intended to fall within the scope of the claims.

The present invention has the following effects of the design can be expected by the configuration as described above.

Instead of the hex nut used to fasten the many stud bolts assembled on the pad flange to the pad flange, the socket according to the present invention enables the fastening of the stud bolt to the pad flange in one operation using a spanner (or impact wrench). As a result, a lot of work time is required when fastening the stud bolts, and the inefficiency factor due to repeated fastening of the stud bolts is removed, thereby reducing productivity and improving productivity.
