Description

Jig in order to do work of side entry type bucket}

The present invention relates to a tool for processing a side entry type bucket, and more particularly, to a tool for processing a side entry type bucket for fixing a bucket to a movable table of a machine tool so that the bucket can be finished.

Generally, a turbine rotor is installed to rotate in a power plant, and hundreds and thousands of buckets are installed in an outer diameter of the turbine rotor.

The above-described turbine rotor is a device for converting thermal energy of high-temperature, high-pressure steam generated in a boiler or a reactor into kinetic energy.

In addition, the above-described turbine rotor is a rotating body rotating at a high speed of 1800 RPM ~ 3600 RPM, the above-described bucket may be configured in various sizes, shapes and shapes depending on the installation position.

As an example of the above-described bucket, there is a side entry type in which an outer end of the bucket is fixed, which will be described with reference to FIG. 1.

1 is a diagram for explaining a side entry type bucket 10.

As shown in FIG. 1, the bucket 10 has a twist part 12 formed at a root part, a vane part 14 formed at one side, and an outer side of the vane part 14. At the end, an entry part 16 is formed.

The above-mentioned twist part 12 is a part which is assembled to the outer diameter of a turbine rotor, and the above-mentioned vane part 14 is a part which is formed in streamline shape and converts the fluid motion of a fluid into rotational kinetic energy, and the above-mentioned entry part 16 ) Is the part that is fixed to the band.

As described above, the bucket 10 has a unique shape for each part, and a machine tool is used to process the shape, and in particular, the bucket 10 is machined to process the entry part 16. The twisted part 12 or the vane part 14 is difficult to be fixed by a general clamp device.

The problem of difficulty in fixing the bucket 10 with the above-described general clamp device will be described in more detail as follows.

The twisted part 12 is formed in a substantially inverted triangle shape as shown in FIG. 1 and both sides are wave-shaped, whereas in general clamp devices, both contact surfaces to be clamped are flat and parallel to the shape of the twisted part 12. This does not fit there is a problem that can not be firmly fixed.

In addition, although the clamp 10 may be clamped with excessively large pressure when clamping the bucket 10 with a general clamp device, in this case, the bucket 10 may be abnormally deformed and may not be smooth when converting fluid energy into rotational kinetic energy. .

Therefore, there is a need for a dedicated tool that can firmly fix the bucket 10 at an appropriate pressure.

In addition, since the shape of the twisted part 12 of the bucket 10 is complicated, it takes a lot of time to prepare when aligning the machining origin when mounting in the machining area of the machine tool, thereby increasing the processing time of the bucket 10 There is a problem.

Therefore, the technical problem to be achieved by the present invention is to process the entry-entry buckets to precisely process the entry part or the vane part by firmly fixing the entry-type bucket at a proper pressure in the machining area of the side machine tool. The purpose is to provide a tool.

It is another object of the present invention to provide a tool for processing side entry type buckets to shorten the preparation time by allowing the machining origin to be quickly aligned when fixing the bucket.

The technical problem to be achieved by the present invention is not limited to the technical problem mentioned above, another technical problem that is not mentioned can be clearly understood by those skilled in the art from the following description. There will be.
