Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automatic sealing material application device for preventing compressed air leakage between compressor disks in a compressor of a jet engine.

(Prior Art) Conventionally, the work of applying sealant between compressor disks has been done manually using a brush or the like, which is extremely inefficient.

(Problems to be Solved by the Invention) The purpose of this invention is to improve the manual coating work as in the prior art, and to automate it to make the coating work more efficient and save labor.

(Solution by invention) An indexing table for a disk on which a blade is assembled is provided adjacent to a blade pushing arm and a sealing material arm supported on a coating device support, and a blade pushing arm is provided at the tip of the blade pushing arm. a cylinder, and a plurality of mono pumps and a cylinder for pressing down the blade are attached to the tip of the sealing material arm, and a plurality of mono pumps and a cylinder for pressing down the blade are attached to the tip of the sealing material arm, and a plurality of mono pumps that can be brought into and out of contact with the sealing material application part of the blade connected to the pot and the sealing material supply pump, The process of moving the blade upward from the disk, supplying sealant to the blade assembly, and returning the blade to its original position can be fully automated.

(Example) FIG. 1 is an overall front view of a coating device according to the present invention. Reference numeral 1 denotes a support body of the coating device, and a blade push-up arm 2 and a sealant arm 3, which can be drawn out and retracted, are attached to the support body 1. Reference numeral 4 designates an indexing table, on which is placed a disk b with blades a installed around it, so that when applying sealant to the insertion portion of each blade a, it can be indexed and applied to adjacent blades in sequence. It's getting old.

A cylinder 5 for pushing up the blade a is attached to the tip of the arm 2 for pushing up the blade. 6 is a sealing material (e.g. Dow
7 is a pump and pot for supplying sealing material.

A cylinder 8 for pushing down the blade a toward the disk is provided at the tip of the sealant arm 3 in a vertically aligned position with the pushing-up cylinder 5. Reference numeral 9 denotes a sealing material supply pump and a pot, which are small discharge pumps driven by cylinders 10, 11, and 12 through piping, so-called mono pumps 13, 1.
It communicates with the cylinder that drives the cylinders 4 and 15.

Note that if the type of sealing material changes, the cylinder should be replaced integrally with the mono pump via the cylinder mounting bolts 16. 17 is CCD
Based on this, it is possible to judge whether the coating status is good or bad.

Although the above embodiment has been described for use in a jet engine compressor, it can be applied to any disc that uses a sealant, allowing efficient sealant application work.

(Operation) The combination of blade a and disk b is placed on the indexing table 4 and set (tilted if necessary), and the cylinder 5 is used to pull out the blade a upward by a height h. The nozzles of the mono pumps 13, 14, 15 driven by the cylinders 10, 11, 12 are pressed against the electric mono pumps 13, 14, 1.
In step 5, sealant is applied to the insertion portion of extrusion blade a into disk b (FIG. 3S). After coating, the blade a is pushed downward with the cylinder 8 and assembled into the disk.

Rotate the indexing table 4 to the next indexing position, perform the same operation on the adjacent blade a,
When sealant application is completed to all blades, the sealant arm 3 is retracted.

(Effects) A part of the blade is removed from the disk, a sealant is applied to that part, and once the sealant has been applied, it can be reassembled to its original position. As a result, the extremely inefficient work of applying sealant to a large number of blades by hand can now be done efficiently and with high precision.
