Description

Technical Field

[0002] A disc ring is installed in the engine, and whether there are cracks in the disc ring has a key impact on the normal operation of the engine. The causes of cracks include material defects, heat treatment and processing, stress concentration, fatigue load and corrosion. After the disc ring is manufactured, the prior art generally fixes the disc ring with a clamp, and then drives the disc ring or the detection camera to rotate through a driving structure, so that the detection camera can detect cracks at different positions on the disc ring.

The first slider 35 is fixedly connected to the bottom of the first fixing plate 38, and the first fixing plate 38 and the outer wall of the control box 4 are connected by a second tension spring 41. The first fixing plate 38 is fixedly installed with a second prism 39, and the end of the second prism 39 away from the first fixing plate 38 is fixedly connected with a protrusion 40 located in the control box 4. The rotating sleeve 28 is fixedly installed with a second fixing plate 45 located in the control box 4, and the end of the second fixing plate 45 away from the rotating sleeve 28 is fixedly connected with an arc plate 46, and the arc plate 46 is provided with an inclined plate 46 that matches the protrusion 40. The control box 4 is provided with a synchronous pusher for pushing the protrusion 40 to move, and the synchronous pusher includes a lifting ring 42 arranged in the control box 4, and a plurality of second sliders 44 are fixedly connected to the bottom of the lifting ring 42, and the number of the second sliders 44 and the protrusion 40 is the same, and the second sliders 44 are provided with inclined surfaces matching the protrusion 40, and the control box 4 is fixedly provided with at least two hydraulic telescopic rods 43, and the telescopic ends of the hydraulic telescopic rods 43 are fixedly connected to the top of the lifting ring 42, and a receiving groove 47 is provided at the top of the first prism 2, and a rolling ball 48 is provided in the receiving groove 47; The lifting ring 42 and the second slider 44 are driven downward by the hydraulic telescopic rod 43, and the inclined surface of the second slider 44 contacts the protrusion 40.

When it is necessary to inspect the part of the disk ring that is blocked by the first prism 2 and the clamping plate 3, as the rotating sleeve 28 rotates, the rotating sleeve 28 drives the second fixed plate 45 to rotate. The movable arc plate 46 moves, and the inclined surface on the arc plate 46 contacts the protrusion 40. With the continuous rotation of the rotating sleeve 28, the protrusion 40 slides on the inclined surface on the arc plate 46. The arc plate 46 drives the first fixed plate 38 to move in the direction away from the control box 4 through the protrusion 40 and the second prism 39, so that the corresponding first prism 2 can be moved downward and the corresponding clamping plate 3 can be moved in the direction away from the disk ring part, so that the single group of first prisms 2 and clamping plates 3 no longer block the disk ring part, so that the first detection camera 6 and the second detection camera 7 can detect the originally blocked parts.

A detection camera 6 moves back and forth in the horizontal direction, so that the two first detection cameras 6 detect the top and bottom of the disc ring, and the two second detection cameras 7 detect the inner wall and outer wall of the disc ring respectively. At the same time, the rotating mechanism drives the installation box 5 to rotate, so that the first detection camera 6 and the second detection camera 7 detect different positions on the disc ring. With the continuous rotation of the installation box 5, the first detection camera 6 and the second detection camera 7, when the second detection camera 7 and the first detection camera 6 need to detect the part of the disc ring blocked by the first prism 2 and the clamping plate 3, the corresponding A first prism 2 moves downward and a corresponding clamping plate 3 moves in a direction away from the disc ring part. With the continuous rotation of the installation box 5, the first detection camera 6 and the second detection camera 7, the first detection camera 6 located at the bottom passes through the top of the corresponding first prism 2, and the second detection camera 7 farthest from the installation box 5 passes between the disc ring part and the corresponding clamping plate 3.

When the corresponding first detection camera 6 and the second detection camera 7 detect After measuring the part of the disk ring part blocked by the first prism 2 and the clamping plate 3, the clamping control structure drives the first prism 2 and the clamping plate 3 to reset to the initial position, the clamping plate 3 clamps the disk ring part again, and the first prism 2 supports the disk ring part. When the installation box 5, the first detection camera 6 and the second detection camera 7 rotate to the initial position, the detection of cracks in the disk ring part can be completed. The clamping control structure drives several clamping plates 3 to move in a direction away from the disk ring part to release the fixation of the disk ring part. The disk ring part only needs to be fixed once to complete the detection of cracks in the disk ring part, thereby improving the detection efficiency. The staff drives the first slide plate 9 to move upward relative to the iron plate 8, and the first slide plate 9 drives the corresponding second detection camera 7 to move upward. The second magnet block 21 is magnetically attracted to the iron plate 8 to prevent the first slide plate 9 and the corresponding second detection camera 7 from obstructing the disk ring from being placed between the two first detection cameras 6. When the disk ring is placed, the staff drives the first slide plate 9 to move downward, the second magnet block 21 is no longer magnetically attracted to the iron plate 8, and the first magnet block 20 is magnetically attracted to the iron plate 8, and the first slide plate 9 drives the corresponding second detection camera 7 to descend to a preset height. The second detection camera 7 can detect the side wall of the disc ring part, the staff drives the first pressing plate 13 and the second pressing plate 15 to move up, the second guide column 16 drives the fixing ring 17 to move up relative to the second support plate 18 and the installation box 5, the first tension spring 19 is in a tensioned state, and the second pressing plate 15 is no longer in contact with the first support plate 14, the first pressing plate 13 is no longer in contact with the iron plate 8, the position restriction of the iron plate 8, the first support plate 14 and the installation plate 10 is released, and the staff drives the installation plate 10 and a corresponding second detection camera 7 relative to the first A guide column 12 and the installation box 5 slide, and the staff drives the iron plate 8 and the corresponding second detection camera 7 to slide relative to the guide frame 11 and the installation box 5, and changes the initial spacing between the two second detection cameras 7 and the disc ring. When the position of the second detection camera 7 is adjusted, the staff releases the first pressing plate 13 and the second pressing plate 15, and the first tension spring 19 drives the fixing ring 17 and the second guide column 16 to move downward, so that the first pressing plate 13 presses the top of the iron plate 8, and the second pressing plate 15 presses the top of the first support plate 14, and the installation plate 1 0 and the iron plate 8 are fixed relative to the installation box 5, so that the two second detection cameras 7 can be fixed relative to the installation box 5, and the first rotating shaft 23 is driven to rotate by the servo motor 22, and the first rotating shaft 23 drives the fixed column 25 to slide back and forth in the rectangular ring 49 through the rotating plate 24, and the fixed column 25 can push the rectangular ring 49 to move back and forth in the horizontal direction, and the rectangular ring 49 drives the first detection camera 6 to move back and forth in the horizontal direction through the first connecting frame 26 and the second slide plate 50, so that the two first detection cameras 6 can respectively detect different positions on the upper and lower sides of the disk ring member; The lifting ring 42 and the second slider 44 are driven downward by the hydraulic telescopic rod 43, and the inclined surface of the second slider 44 contacts the protrusion 40. As the second slider 44 continues to move downward, the second slider 44 pushes the protrusion 40 and the second prism 39 to move horizontally, so that the first fixed plate 38 moves in a direction away from the control box 4. The second tension spring 41 is in a tensioned state. The first fixed plate 38 drives the clamping plate 3 to move through the first slider 35 and the second connecting frame 36. The spacing between the several clamping plates 3 increases, and the bottom end of the first prism 2 slides on the inclined surface of the first slider 35. The first prism 2 moves downward. When the first prism 2 and the clamping plate 3 move to the preset position, the staff drives the disk ring to be placed on several first prisms 2. The first prism 2 supports the disc ring, and the ball 48 is in contact with the bottom of the disc ring. The design of the ball 48 reduces the friction force on the disc ring when it moves horizontally relative to the first prism 2. At this time, the lifting ring 42 is driven upward by the hydraulic telescopic rod 43, so that the second slider 44 no longer supports the protrusion 40. The second tension spring 41 drives the first fixed plate 38 and the second prism 39 to move in the opposite direction, so that the first slider 35 pushes the first prism 2 and the disc ring to move upward, and the first slider 35 drives the clamping plate 3 to move toward the disc ring through the second connecting frame 36. The disc ring is pushed to move by several clamping plates 3, and the disc ring moves horizontally relative to the first prism 2. Finally, several clamping plates 3 clamp the disc ring. When it is necessary to inspect the disk ring, the servo motor 22 drives the first rotating shaft 23 to rotate, the first rotating shaft 23 drives the worm 33 to rotate, the worm 33 drives the second rotating shaft 30 and the second gear 31 to rotate relative to the installation box 5 through the worm gear 32, and the installation box 5 and the rotating sleeve 28 are rotatably connected relative to the control box 4. When the second gear 31 rotates, the second gear 31 rolls on the first gear 29, so that the installation box 5 rotates with the support column 27 and the rotating sleeve 28 as the center, so that the first inspection camera 6 and the second inspection camera 7 can inspect different positions on the disk ring. When it is necessary to inspect the part of the disk ring that is blocked by the first prism 2 and the clamping plate 3, as the rotating sleeve 28 rotates, the rotating sleeve 28 drives the second fixed plate 45 to rotate. The movable arc plate 46 moves, and the inclined surface on the arc plate 46 contacts the protrusion 40. With the continuous rotation of the rotating sleeve 28, the protrusion 40 slides on the inclined surface on the arc plate 46. The arc plate 46 drives the first fixed plate 38 to move in the direction away from the control box 4 through the protrusion 40 and the second prism 39, so that the corresponding first prism 2 can be moved downward and the corresponding clamping plate 3 can be moved in the direction away from the disk ring part, so that the single group of first prisms 2 and clamping plates 3 no longer block the disk ring part, so that the first detection camera 6 and the second detection camera 7 can detect the originally blocked parts. The first detection camera 6 and the second detection camera 7 can detect the parts of the disk ring part blocked by several groups of first prisms 2 and clamping plates 3 in turn.
