Description

Technical Field

[0001] The invention relates to the field of vacuum arc ion plating of aircraft engine blades, and in particular to a supporting and protecting device for vacuum arc ion plating of aircraft engine blades. Background Art

[0002] Vacuum arc ion plating is a method that uses high-voltage arc discharge to generate plasma, accelerates ions in a vacuum environment, and deposits them onto the surface of the substrate. For aircraft engine blades, metals, alloys, or ceramic materials are usually used as coating materials. The coating material is converted into ions by arc discharge, forming plasma and is accelerated and deposited onto the blade surface. In order to avoid the coating being deposited onto non-deposition surfaces such as the tenon of the aircraft blade during the vacuum arc ion plating process, the aircraft blade is unstable and the problem of touching the clean surface to be deposited during the clamping device occurs. Before the aircraft blade coating is prepared, the surface to be deposited on the aircraft blade needs to be cleaned and then placed in the coating equipment for coating.

[0003] When loading the blades into the coating equipment after cleaning, the problem of holding the clean blade body for loading often occurs, causing surface contamination and unqualified coating bonding strength. In addition, during the transfer process after cleaning, the external environment may cause contamination to the blade surface. Therefore, it is necessary to seek a new vacuum arc ion plating aviation blade protection device. Summary of the Invention

The right end of the circular block 804 is fixedly connected to the left surface of the gear 803. The interior of the circular block 804 is provided with a second limiting groove corresponding to the limiting plug-in 504.

The annular gear plate 802 is fixedly connected to the upper surface of the mounting rod 2 and is slidably connected to the inner surface of the shell 805.

[0027] The rotating device 8 and the clamping device 4 can be arranged in plurality around the rotating support rod 10 and can open the dust cover 1 synchronously to improve efficiency.

[0028] Working principle: After cleaning the blades, snap the plug-in part 602 into the inner part of the limiting rotating disk 501, and use the rubber material to block the gap to reduce the entry of arc ions. Then close the second opening and closing plate 901 through the hinge at the front end, and then put the limiting head 903 on the slide rod 902 into the bottom end along the slide groove 904, and then rotate the slide rod 902 to limit the second opening and closing plate 901 on the limiting rotating disk 501 to limit the plug-in part 602. Then manually close the dust cover 1. Lift up through the hinge on the right end, move the inclined surface of the inclined rod 401 at the upper end of the dust cover 1 to the inner side of the fixed insert plate 408 and push the sliding rod 404 into the fixed insert plate 408, so that the sliding rod 404 slides into the limiting hole on the inclined rod 401 through the action of the spring 405 to limit the dust cover 1. At the same time, the movement of the dust cover 1 drives the gear rod 30403 to move on the first fixed plate 30401, thereby closing the first opening and closing plate 301. If it needs to be transported later, Figure 4The whole is transported in the arc coating equipment. When arc coating is required, the limiting plug-in 504 is clamped in the circular block 804, and then the lower end of the mounting rod 2 and the upper end of the rotating support rod 10 are installed in the arc coating equipment. Then, the downward moving kit 407 is pressed down in the arc coating equipment to make the rollers on both sides of the support plate 406 contact the inclined surface set on the inclined surface block 402, thereby moving the inclined surface block 402 outward, and then driving the sliding rod 404 to move to release the limit on the inclined surface rod 401. At the same time, the limit is released, and the hinge connected to the right end of the dust cover 1 is used as a circle under the influence of the dust cover 1's own gravity. The center moves downward, and the dust cover 1 moves while driving the gear rod 30403 to move on the arc-shaped gear plate 30402, thereby driving the rotating rod 310 to rotate. The rotation of the rotating rod 310 drives the second connecting member 308 to move. The second connecting member 308 moves through the first connecting member 307 to drive the moving rod 303 to move upward in the sliding groove 309. The moving rod 303 moves upward and drives the limiting short rod 306 and the top rod 302 to move upward. Then, the moving rod 303 moves to the arc groove at the edge of the sliding groove 309, thereby driving the top rod 302 to tilt and then drive the first opening and closing plate 30 1 tilts outward to open the first opening and closing plate 301 to expose the blade body 6. At the same time, a magnet is installed under the dust cover 1. When the dust cover 1 moves down, it contacts the position of the magnetic plate 11 and is attracted to limit the dust cover 1. The downward moving kit 407 continues to move downward and moves below the upper slope of the inclined surface of the inclined surface block 402 to the top of the rollers on both sides of the support plate 406 to limit it to a certain extent. The groove on the downward moving kit 407 moves to the fixed plug-in plate 408 for nesting, further producing a limiting effect. Later, when coating is performed, the upper part of the rotating support rod 10 is installed at the output end of the motor. The lower end of the mounting rod 2 is fixedly installed. When the rotating support rod 10 rotates, the gear 803 on the rotating device 8 moves on the annular gear plate 802 and then drives the limiting plug-in 504 to rotate through the circular block 804. The limiting plug-in 504 rotates to drive the limiting rotating disk 501 to rotate, thereby driving the blade body 6 to rotate while rotating around the rotating support rod 10. When the gear 803 moves a distance of a tooth surface segment on the annular gear plate 802, the gear 803 is released from the limit on the smooth surface, and the blade body 6 is returned to its original position by the action of the torsion spring 503, and then the rotation is repeated to perform the coating operation.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
