Description

Technical Field [0001] The present invention relates to a sealing ring machining apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing ring processing apparatus and a method for operating the same, and more particularly, to a sealing ring processing apparatus including a configuration capable of preventing deformation of a sealing ring during a processing process will be.

Fig. 1 is a perspective view showing a state in which a sealing ring according to a conventional technique is machined.

1, when the sealing ring according to the prior art is machined, the supporting ring 10 to be machined is fixed to the upper portion of the mounting table 30 by using a plurality of fixing clamps 40, And then the work is performed.

At this time, the sealing ring is relatively thin and has a complicated process, and a plurality of fixing clamps 40 and 50 should be disposed at appropriate positions.

In the case of the ring device for sealing according to the related art, a fixed clamp having a general structure is used without using a fixed clamp including a specific structure corresponding to the ring for sealing.

Therefore, a plurality of fixing clamps 40, 50 are used to fix the sealing ring stably and firmly.

Further, in the case of the conventional ring processing apparatus according to the prior art, the positions of the fixing clamps 40 and 50 when changing the inner diameter side of the sealing ring and the outer diameter side must be changed.

In this case, since a plurality of clamps 40 and 50 must be removed and fixed again after placement, a large amount of time is required for the machining operation, and the work force is also excessively consumed.

Moreover, since the prior art silent ring includes a relatively thin structure, when the position of the fixing clamp is misaligned, there is a problem that deformation occurs in the final product.

Therefore, there is a need for a sealing ring processing apparatus capable of solving the above-mentioned problems in the related art and a method of operating the sealing ring processing apparatus.
