Description

The utility model relates to mechanical engineering and can be used for applying protective coatings to parts of aircraft, mainly to the blades of gas turbine engines.

A device is known for use in an apparatus for applying protective coatings to parts, including devices for attaching a plurality of parts to be coated (patent RU No. 2161075, B 05 C 13/00, C 23 C 14/56, 1997).

On the known device it is impossible to ensure high-quality application of protective coatings on the surface of the feather blades in one continuous process.

The closest in technical essence is the installation for applying protective coatings containing an element for fixing the blades and a mechanism for vertical movement of the plasma torch ("Fundamentals of the technology of creating gas turbine engines for long-haul aircraft" edited by A.G. Bratukhin, Yu.E. Reshetnikov, A.A. . Inozemtseva, M., "Aviatekhinform", 1999, p.497).

On the known installation it is impossible to ensure high-quality application of protective coatings on the surface of the feather blades in one continuous process.

The technical result of the utility model is to increase the quality of the application of protective coatings on the surface of the blade feather in one continuous process, including the transitions of the blade feather to the shelf (mating radii).

The technical result is achieved by the fact that the installation for applying protective coatings, comprising a device for fixing the blades and a mechanism for vertical movement of the plasma torch, further comprises a mechanism for longitudinal movement of the blades and a device for rotating the blades, made in the form of a U-shaped channel, the first shelf of which is pivotally mounted on the holder, and a bracket is pivotally mounted on the second shelf, and rollers for interacting with copiers are mounted on the first shelf of the channel and on the bracket.

The installation includes a device 1 for securing the blades 2, a vertical movement mechanism 3 of the plasma torch 4, a longitudinal movement mechanism

5 blades 2 and a device for rotating the blades 2. The device for rotating the blades 2 is made in the form of a U-shaped channel 6. The first shelf 7 of the U-shaped channel 6 is pivotally mounted on the holder 8 with the possibility of turning the U-shaped channel 6 around axis 9. On the second shelf 10 of the U-shaped channel 6, the bracket 11 is pivotally mounted rotatably around the axis 12. The bracket 11 is rigidly connected to the device 1. On the shelf 7 and on the bracket 11, rollers 13, 14 are installed for interaction with the copiers 15, 16. The device for rotating the blades 2 is provided turning mechanism 17 l patki 2 about the axis "a" extending along the center line of the leading edge of the blade 2. A spring 18 is mounted to act on the bracket 10.

Installation works as follows.

In the device 1, a blade 2 with two shelves is installed and fixed. The plasma torch 4 and the longitudinal movement mechanism 5 are in the initial position. The blade 2 is brought out of the zone of operation of the plasma torch 4 (figa). Turn on the plasma torch 4 and the mechanism of longitudinal movement 5. In this case, the device for rotating the blades 2 begins to turn. From the starting position (Fig. 3, point (1)), the blade 2 enters the zone of the plasma jet of the plasma torch 4. The transition of the feather of the blade 2 to the shelf (mating radius) is sprayed (Fig. 4b). The U-shaped channel 6 continues to rotate around axis 9 together with the bracket 11 and with the device 1. The plasma jet of the plasma torch 4 passes from the radius of pairing to the feather of the blade 2. The rotation of the device 1 with the blade 2 is carried out by the roller 13, which comes off the copier 15. The spring 18 provides the installation of the device 1 together with the blade 2 perpendicular to the jet of the plasma torch 4 (pigv), increasing the quality of the spraying of the blade. There is a longitudinal spraying of the feather of the blade 2 along the first line (Fig. 3, direction (2)). When approaching the second shelf of the blade 2, the roller 14 is rolled onto the copier 16. The bracket 11 rotates around the axis 12. The spraying of the radius of conjugation of the blade 2 (Fig. 4d) continues, followed by the exit of the plasma jet of the plasma torch 4 (Fig. 4d). The spraying of the first row of the feather of the blade 2 is finished. The vertical movement mechanism 3 is turned on and the plasma jet of the plasma torch 4 goes to the next row of spraying of the feather of the blade 2 (Fig. 3, direction (3)}. Similarly, the deposition occurs in the opposite direction (Fig. 3, direction ( 4)) The cycle is repeated the number of times specified by the program (Fig. 3, directions (5-8)). To continue the continuous spraying of the next lines, the rotation mechanism 17 of the blade 2 around the axis “a” is turned on. The position of the pen blade 2 when turning around the axis “a” "shown and Figures 5a-5e. The choice of the transfer (via the vertical movement mechanism 3 of the plasma torch 4, or by turning the blade mechanism 17 2 around the axis "a") is carried out by a preset program depending on the shape of the blade 2.

The proposed installation improves the quality of the application of protective coatings on the surface of the pen blades in a single continuous process, including the radius of mate blades.
