Description

Jig for eccentricity Labyrinth packing ring for eccentric labyrinth packing ring

[0001] The present invention relates to a variable eccentric jig for eccentric labyrinth packing ring processing, in which a dedicated paper for exclusive use of an eccentric labyrinth packing ring is produced, and a variable eccentric jig for eccentric labyrinth packing ring processing, .

Typically labyrinth packing rings are installed between the diaphragm of a ship turbine and the turbine casing to improve the efficiency of the turbine and thus play a major role in the production of electric power used in ships.

However, packing rings are frequently damaged due to long-term use in high temperature, high pressure and dynamic environment, deformation due to thermal expansion which is a poor operating condition, accumulation of fatigue due to frequent starting and stopping, oxidation and corrosion .

As a result, the rapid replacement of high quality turbine seals is an important part of turbine fabrication and maintenance. It is a reality that development for better and quicker procurement of products is essential.

However, conventional CNG machining is concentric and can not be eccentrically machined, so it requires skillful work techniques, which makes it inefficient in terms of cost and production.

As a technique related to a conventional labyrinth packing ring, Korean Patent Registration No. 10-1118379 discloses a tooth surface processing apparatus for labyrinth packing.

A fixing vise (2) mounted on the frame (1) and configured to be screwed and configured to fix the packing (9) on both the left and right sides; A stopper (3) provided on the frame (1) at the rear of the packing (9) between the fixing vise (2) and supporting the packing (9) at the rear portion; Left and right swing mechanisms (4) installed on the frame (1); A forward / rearward feed mechanism 5 installed on the upper portion of the left / right swing mechanism 4; An up-and-down conveying mechanism (6) installed so as to be able to move up and down with the front and rear conveying mechanism (5); Left and right horizontal conveying mechanisms (7) installed on one side of the upper conveying mechanism (6); And a machining cutter mechanism 8 installed on one side of the left and right horizontal transport mechanisms 7 and capable of machining both sides of the teeth of the packing 9 at the same time.

However, in the prior art, there has been a problem that the eccentric labyrinth packing can not be smoothly eccentrically machined.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to provide a variable eccentric jig for eccentric labyrinth packing ring processing that can easily process an eccentric labyrinth packing ring by manufacturing a special paper for easy eccentric machining I want to do that.

According to an aspect of the present invention, there is provided a slide fastener comprising: a lower jig having a slide groove formed therein; An upper jig provided at an upper portion of the lower jig, the lower jig having a slide protrusion corresponding to the slide groove; A fixture coupled to an upper portion of the upper jig to receive and fix the eccentric labyrinth packing ring; And a transfer control device provided between the lower jig and the upper jig to move the upper jig to one side.

The fixture may further include a groove for receiving an end diameter of the eccentric labyrinth packing ring at an upper center portion thereof and a holder for fixing an end diameter of the eccentric labyrinth packing ring at an upper edge thereof.

The feed adjusting device may include a feed nut coupled to the slide protrusion, and a ball screw coupled to the feed nut and configured to rotate the feed nut according to the rotation.

According to the present invention having the above-described configuration, the following effects can be expected.

First, a special jig for processing the eccentric labyrinth packing ring is developed, and the eccentric labyrinth packing ring can be easily fixed.

Further, the eccentric labyrinth packing ring can be eccentrically moved by simply moving the upper jig to one side with the ball screw, so eccentric machining is easy.

FIG. 1 is a configuration diagram of a conventional tooth-surface machining apparatus for a labyrinth packing.
2 is a perspective view of a variable eccentric jig for eccentric labyrinth packing ringing according to an embodiment of the present invention.
3 is a front view of Fig.
4 is a top view of Fig.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Fig. 2 is a perspective view of a variable eccentric jig for eccentric labyrinth packing ringing according to an embodiment of the present invention, Fig. 3 is a front view of Fig. 2, and Fig. 4 is a top view of Fig.

Referring to FIG. 2, the variable eccentric jig for eccentric labyrinth packing according to the present invention includes a lower jig 100, an upper jig 200, a fixture 300, and a feed adjusting device 400.

Here, the eccentric labyrinth packing ring R means a packing used for preventing the gas from leaking through a gap between the casing and the rotating shaft, and the blade having the stepped end is formed by protruding.

The lower jig 100 is fixed to the chuck and has a disk shape, and a slide groove 120 is formed on the upper side.

Here, the chuck fixes the workpiece in the rotary machining device so that the rotation is interlocked.

The upper jig 200 is provided on the lower jig 100 and is slid in a circular plate shape. The lower jig 200 has a slide protrusion 220 corresponding to the slide groove 120.

Here, the upper jig 200 is inserted from a side surface of the lower jig 100. Therefore, it is preferable that the slide groove 120 of the lower jig 100 is formed so as to become narrower toward the upper end, and the slide protrusion 220 is formed to be inclined to widen toward the lower end.

The fixture 300 is coupled to the upper jig 200 at an upper portion thereof to receive and fix the eccentric labyrinth packing ring R.

That is, the fixture 300 can fix the eccentric labyrinth packing ring R exclusively.

The fixture 300 is formed in a circular plate shape and has a groove 320 for accommodating the end diameter of the eccentric labyrinth packing ring R at an upper center portion of the fixture 300. An eccentric labyrinth packing A plurality of holders 340 for fixing the end diameter of the ring R are provided.

Here, the end diameter of the eccentric labyrinth packing ring R may be a blade (sealing role).

As shown in FIG. 3, the holder 340 is formed in a shape of a letter 'A' that is bent in the horizontal direction and protruded in the vertical direction from the fixture 300, so that the eccentric labyrinth packing ring R is fixed Where the holder 340 can be detachably coupled to the fixture 300 by bolting.

The feed regulating device 400 is provided between the lower jig 100 and the upper jig 200 to move the eccentric labyrinth packing ring R. [

A semicircular groove is further formed in the slide groove 120 of the lower jig 100 and a semicircular groove is formed in the slide protrusion 220 of the upper jig 200 to correspond to the semicircular groove, The transfer regulating device 400 can be provided.

That is, the upper jig 200 can be moved to one side, and the eccentric labyrinth packing ring R received and fixed to the fixture 300 is interlocked with the movement of the upper jig 200, do.

The feed adjusting device 400 includes a feed nut 420 coupled to the slide protrusion 220 and a screw 440 coupled to the feed nut 420 and rotating the feed nut 420 in accordance with rotation And the ball screw is constituted.

Therefore, when the screw 440 is simply rotated, the feed nut 420 is moved, and the upper jig 200 is moved accordingly.

4, the eccentric labyrinth packing ring R fixed to the fastener 300 on the upper jig 200 moves eccentrically to one side, thereby facilitating eccentric machining.

As described above, it can be seen that the present invention is based on providing a variable eccentric jig for eccentric labyrinth packing ring processing, and within the scope of the basic idea of the present invention, Of course, many other variations are possible for those with knowledge.
