Referring to the drawings, the case 10 of the compressor is formed of a plurality of stator vanes (11) installed along the circumferential direction on the same plane as a whole as a circle, and each vane assembly provided as a circle is stacked as a stacked form. . Each stator vane 11 is fixed to the shroud 12 forming the outer side of the case, the inner side 13 is formed with a groove in which a damper and honeycomb seal (see Fig. 2) can be installed. Although not shown in the figure, a disk having movable blades is installed at the inner center of the case 10 of the compressor, and each movable blade rotates between the installed stator vanes 11 having different heights to perform a multi-stage compression action. Perform.

2A is a schematic exploded perspective view of a stator vane assembly in the form of a segment, and FIG. 2B is an explanatory view of a portion of FIG. 2A.

Referring to the figure, the outer end of the stator vane 21 is fixed to the shroud 22, the groove 23a is formed in the inner surface 23 of the stator vane 21. The base 25a of the honeycomb seal 25 is inserted into the groove 23a, and the damper 24 is also inserted. Herein, the honeycomb seal 25 functions as a seal between the movable blade and the stator vane 21 when the air is compressed, and the damper 24 is a base 25a of the honeycomb seal 25 and a stator vane ( Between 21) the honeycomb seal 25 acts as a spring to minimize play during rotation of the movable blades.

According to the prior art, the process of attaching the honeycomb seal 25 to the groove 23a formed in the stator vanes has been carried out entirely by hand, and this operation has been dependent on the accuracy of the operator's skill. This will be described in more detail as follows.

First, the worker fixes the segmented stator vane assembly as shown in FIG. 2A using a jig and assembles the damper 24 into the groove 23a of the stator vane 25. The assembly of the damper 24 is performed by press-fitting in the radially outward direction against the longitudinal surface of the longitudinal groove 23a of the damper 24. The assembly of the honeycomb seal 25 is then carried out by pushing the honeycomb seal 25 against its groove 25a from its circumferential end. That is, since the cross section of the base 25a of the honeycomb seal 25 is formed to correspond to the cross section of the groove 23a, it is a method of gradually pushing in the circumferential direction from the groove 23a formed in the form of a segment. The operator first grabs the honeycomb seal 25 by hand, matches the end of the honeycomb seal 25 with the end of the groove 23a, and pushes it in. If the honeycomb seal 25 is not inserted smoothly due to the elastic force of the damper 24 or the curved shape of the groove 23a itself, the honeycomb seal 25 is priced using a plastic hammer.

The prior art work method as described above has the following problems. First of all, the process performed by hand takes a long time, so productivity is reduced, and the accuracy of the work depends on the skill of the operator. In addition, damage to parts is apt to occur in the process of priceing honeycomb seals, which are expensive parts, with plastic hammer, and errors accumulated by minor parts damage significantly affect the compression efficiency.

The present invention has been made to solve the above problems, it is an object of the present invention to provide a honeycomb seal mounter that can more easily and accurately assemble the honeycomb seal.

It is another object of the present invention to provide a honeycomb seal mounter capable of standardizing work and improving productivity.
