Description

A tooling sleeve for fast screwing in of double-ended studs

technical field

The utility model relates to the technical field of assembly or installation of wind power generating sets, in particular to a frock sleeve used for fast screwing in of double-ended studs.

Background technique

At present, when wind turbines are assembled in workshops or installed in wind farms, studs (nominal diameter D≥M36) are generally used to connect large components. One end of the double-ended stud needs to be screwed into the metal matrix. In order to realize the fast screwing of the double-ended stud into the matrix, some manufacturers generally use special sleeves for double-ended studs. The existing double-ended stud sleeves on the market generally can only meet the small studs with a nominal diameter D≤M36. There is no suitable tool for the bolts with a nominal diameter D≥M36, so the screwing method is mostly hand-tightened. This method makes the installation speed of the stud bolts slow and the efficiency is extremely low, and it is difficult to meet the installation requirements of wind farms, especially offshore wind farms.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a tooling sleeve for fast screwing in of double-ended studs, which can effectively solve the problem of quickly installing double-ended studs.

In order to achieve the above purpose, the technical solution provided by the utility model is: a tooling sleeve for fast screwing in of double-ended studs, including a sleeve body, and the sleeve body is a cylinder with an outer hexagonal head at one end structure, the other end of which is open, and the inner cavity is formed with an internal thread that engages with the external thread of the stud, and the stud is fixed on the sleeve body through threaded connection, and the outer hexagonal head is formed with a The coaxial inner square hole of the sleeve body is used for the installation of the square drive head of the electric wrench. Two small round holes on the same axis are respectively formed on the two opposite sides of the outer hexagonal head. The steel ball of the square driving head of the electric wrench is stuck or the iron wire is penetrated to fix the electric wrench and the socket body, and the electric wrench is driven to quickly screw the double-ended stud into the matrix.

Further, an anti-seize spherical body is welded on the inner cavity of the sleeve body near the end surface of the outer hexagon head.

Further, the inner edge of the opening of the sleeve body is chamfered.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. The utility model is easy to operate, which makes the double-ended studs screwed in more quickly and greatly improves the installation efficiency.

2. Compared with the existing similar designs, the utility model also has an anti-seize function (specifically, an anti-seize spherical body is welded inside the cylindrical structure), which can prevent the double-ended stud from engaging too closely with the internal thread of the sleeve , resulting in difficulty in the withdrawal of the later sleeve.

3. The utility model has the advantages of simple structure, few parts, short processing cycle, low cost, convenient installation and disassembly, light weight, convenient and labor-saving operation.

4. The utility model can be used repeatedly, reduces the cost, and is economical.

Detailed ways

Below in conjunction with specific embodiment the utility model is further described.

As shown in Figures 1 to 3, the tooling sleeve provided by this embodiment for fast screwing in of double-ended studs includes a sleeve body 1, and the sleeve body 1 is cylindrical with an outer hexagonal head 12 at one end. structure, its other end is open, and the inner edge of the opening is formed with a chamfer 16, the inner cavity of the sleeve body 1 is formed with an internal thread that engages with the external thread of the double-ended stud, and the double-ended stud (not shown in the figure ) and the sleeve body 1 are fixed through threaded connection, and the inner cavity of the sleeve body 1 is welded with an anti-seize spherical body 13 on the end surface close to the outer hexagonal head 12, which can prevent the double-ended stud and the internal thread of the sleeve body 1 from If the engagement is too close, it will be difficult to withdraw the socket body 1 in the later stage. The inner square hole 14 coaxial with the socket body 1 is formed inside the outer hexagonal head 12, which is used for the square drive of the electric wrench (not shown in the figure) For the installation of the head, two small round holes 15 on the same axis are respectively formed on the two opposite sides of the outer hexagon head 12, which are used to block the steel ball of the square drive head of the electric wrench or penetrate the iron wire, so that the The electric wrench is fixed to the sleeve body 1, and the electric wrench is driven to quickly screw the stud into the base body (not shown in the figure).

When in use, first fix the double-ended stud and the sleeve body 1 through threaded connection, thereby fixing the double-ended stud on the sleeve body 1; secondly, install the square driving head of the electric wrench in the sleeve body 1 In the square hole 14, the steel ball of the square driving head of the electric wrench is stuck or the iron wire is penetrated through the two small round holes 15, so that the electric wrench and the sleeve body 1 are fixed; finally, the electric wrench is driven to turn the double-ended screw. The column is quickly screwed into the base body, and then withdraws from the sleeve body 1 . Due to the design of the anti-blocking spherical body 13 in the sleeve body 1, after the double-ended stud is screwed into the matrix, it can ensure that the sleeve body 1 exits smoothly after the installation of the double-ended stud is completed.

The implementation examples described above are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all changes made according to the shape and principle of the present utility model should be covered by the scope of the present utility model. within the scope of protection.
