2. Description of the Related Art As a technique for joining hard members such as metals, ceramics, and FRPs, joining using a resin is performed. For example, an inlet guide vane (for an air gas turbine engine for an aircraft) is used. I
A urethane resin is used between the GV) and the shroud to join them. When replacing or repairing the vane when the engine is overhauled, the shroud and the vane need to be separated (disassembled). In the related art, the shroud and the vane are separated by immersing the joint in a chemical solution capable of dissolving the urethane resin and dissolving the urethane resin. Furthermore, by immersing in the chemical solution, the urethane resin adhering to the shroud or the vane is also removed.

[0003]

However, in the conventional operation using a chemical solution, waste liquid treatment after dissolving the urethane resin is troublesome, and an increase in equipment costs such as the necessity of a large-scale treatment apparatus is required. Has been invited. Further, the working environment is not good due to the scattering of the chemical solution and the gas generated from the solution, which causes problems such as adhesion of the solution to the operator and gas suction, which leads to a reduction in working efficiency.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and can cut a resin joint between members without using a chemical solution to easily and easily separate members from each other.

FIG. 1 is a schematic diagram illustrating a use state of a member separating device 1 that performs a member separating method according to the present invention. As shown in FIG. 1, the member separating device 1 moves a cutting nozzle 2 for spraying high-pressure water W, a high-pressure water supply device 3 for supplying high-pressure water to the cutting nozzle 2, and a cutting nozzle 2. The driving device 4 is schematically configured. The member separating device 1 is housed in a chamber (not shown) in order to prevent the high-pressure water W injected from the cutting nozzle 2 from scattering around, and furthermore, the high-pressure water W after the injection is provided in the chamber. A tray for receiving water W is arranged.

The cutting nozzle 2 is connected to a resin joint 8 described later.
What has the diameter of the cutting nozzle which can cut | disconnect is used. The high-pressure water supply device 3 is for supplying water to the cutting nozzle 2 at a high pressure, and various pumps and the like are used. The driving device 4 moves the cutting nozzle 2 three-dimensionally, and uses a robot arm or the like. The operations of the high-pressure water supply device 3 and the driving device 4 are controlled by the control device 5.

The parameters set by the control device 5 include the nozzle diameter of the cutting nozzle 2 and the high-pressure water W

Among them, the distance to the resin joint 8 is a contact-type distance measuring device using ultrasonic waves or laser interference, or a contact-type distance such that a measuring rod is extended and brought into contact with the vicinity of a cut portion. The measurement is performed using a measurement device, and the measurement result is input to the control device 5.

As shown in FIG. 2, the work object X is a shroud 6 and an IGV (inlet guide vane) 7 in a gas turbine engine for an aircraft, each of which is a hard member such as metal or FRP, and both are urethane. It is integrated by a resin joint 8. The work target X is divided into a plurality of segments, first divided into segments, and then installed and fixed at predetermined positions of the member separating device 1 for each part Xa.

The fixing of the part Xa is performed by a fixing jig (not shown), and the resin joint 8 to be cut is held at a fixed position. After fixing the part Xa, the high-pressure water supply device 3 is driven to eject high-pressure water W from the cutting nozzle 2, and the driving device 4 is driven to drive the resin bonding portion 8.
The cutting nozzle 2 is moved around the end face of the IGV 7 at a predetermined feed speed while monitoring the distance between the cutting nozzle 2 and the cutting nozzle 2. The resin joint 8 is cut by the movement of the high-pressure water W, and the cutting is completed when the cutting nozzle 2 has made one round, whereby the shroud 6 and the IGV 7 are separated.

At this time, the high-pressure water W at the time of cutting is received by the tray together with the resin pieces in the chamber and discharged out of the chamber. In addition, unlike the chemical solution, since the urethane resin is not dissolved in water, it is possible to easily remove the mixed resin pieces by filtering the waste liquid, thereby reducing equipment costs required for waste liquid treatment. it can. In addition, since the shroud 6 and the IGV 7 are easily and easily separated from each other and cut using the high-pressure water W, no toxic gas is generated at the time of work, and the working environment is not deteriorated.

The switching device 11 may be set so as to supply high-pressure water to both of them. In this use mode, the cutting of the resin joint portion 8 and the peeling of the remaining resin 8a are performed almost simultaneously, and the work time is reduced. Can be further reduced.

The various shapes and combinations of the constituent members shown in the above embodiment are merely examples, and various changes can be made based on design requirements without departing from the spirit of the present invention. For example, in the illustrated example, IGV7
Cutting nozzle 2 by driving devices 4 and 10 while fixing
