[0002] In existing applications of composite material flat plates used in aerospace components, the plates need to be centered and fixed with rivets after installation. In actual use, the central through hole of this type of aerospace composite support plate is centered longitudinally and determined laterally by referring to the actual assembly position. Therefore, before processing, center positioning or marking is required. This can be achieved through drilling equipment or manual drilling equipment during subsequent drilling operations. The present invention discloses a centering and marking device for this type of composite material flat plate.

[0003] In existing technologies, this type of line drawing is mostly done manually, which has the following drawbacks: 1. When there are a large number of such parts, manual line drawing is inefficient and has a large accuracy error; 2. When drawing lines on composite boards with a width of more than 1.5 meters, it is very inconvenient to simply measure and draw the lines manually. The operator can only lie prone on the board to draw the lines, which has a large working error and seriously affects the accuracy and speed of line drawing.

[0004] In light of the above problems, as those skilled in the art, there is an urgent need to design an operating platform that can be fixed to the rear of the sheet metal cutting production line, can achieve the positioning of the sheet metal through a positioning device, and can achieve positioning and line drawing in the central area of ​​the composite support plate after positioning.

Based on understanding the present technical solution, further technical extensions can be made. If such technical extensions cover the present technical solution as a whole, they should fall within the protection scope of the present technical solution.

[0037] As shown in the attached figure, a center through-hole positioning device for an aviation composite support plate includes a support frame 1. A clamping platform 10 is mounted on the upper part of the support frame 1. A central turntable 5 is mounted on the clamping platform 10. The central turntable 5 is locked and fixed at the center of the clamping platform 10 by a fixing plate 50. A rotating component 51 is fixed on the central turntable 5, and the rotating component 51 rotates or swings synchronously with the central turntable 5. The central turntable 5 is connected to and driven by a turntable drive motor 6 at the bottom of the clamping platform 10. The turntable drive motor 6 is a servo motor.

[0038] The central turntable 5 is equipped with longitudinal tracks 13 on both its front and rear sides. Each set of longitudinal tracks 13 has a positioning support 4, which is equipped with several positioning pressing wheels 45. Furthermore, each positioning support 4 has a longitudinal sliding block 41, with a base plate 42 on top. A top plate 44 is supported and fixed by columns 43 on the base plate 42. Several positioning pressing wheels 45 are evenly distributed laterally on the top plate 44. Two linkage rods 8 are hinged to the two positioning support 4s, one at the front and one at the rear. These linkage rods 8 are hinged to the rotating component 51 on the central turntable 5. Each linkage rod 8 has an outer fixing plate 81 and an inner fixing plate 82. In this embodiment, the outer fixing plate 81 is hinged to the base plate 42, and the inner fixing plate 82 is hinged to the rotating component 51 on the central turntable 5. The linkage rods 8 are located in the space between the top plate 44 and the base plate 42. When the aforementioned positioning extrusion rollers 45 extrude and position the composite support plate 9, they can achieve sliding positioning. The positioning extrusion rollers 45 always rotate under external force, which will not cause damage to the composite support plate 9. Furthermore, during the positioning process, the positioning extrusion rollers 45 on the two positioning support members 4 are linked together, which can simultaneously extrude the side of the composite support plate 9, resulting in a more stable extrusion positioning effect.

[0039] This invention features a conveyor belt mounted on the upper part of the clamping platform 10. More specifically, the conveyor belt is an independent conveyor belt 31, which is equipped with independent drive wheels 3 at both ends. The independent drive wheels 3 drive the independent conveyor belt 31 to move laterally. This independent conveyor belt 31 can be connected to a sheet metal production equipment or a cutting equipment to achieve production line docking. Through these devices, the positioning lines 91 on the external composite support plate 9 can be guided to the independent conveyor belt 31.

[0040] The top of the clamping platform 10 is supported by a secondary support frame 2, which supports the top support beam 21. A top longitudinal track 22 is mounted on the top support beam 21, and a top slider 23 is mounted on the top longitudinal track 22. The top support plate 24 is fixed by the top slider 23. A vertical drive cylinder 25 is vertically fixed on the top support plate 24. A horizontal rail support rod 261 is mounted on the drive rod 26 of the vertical drive cylinder 25, which supports the horizontal line drawing track 262. A slider clamping frame 27 is mounted on the slider clamping frame 27, and a locking screw can be mounted on the slider clamping frame 27. The line drawing positioning pen 28 is fixed by adjusting and locking the slider clamping frame 27. Furthermore, a positioning line 211 is mounted on the top support beam 21, and a reference point 231 is mounted on the top slider 23. The reference point 231 and the positioning line 211 are used in conjunction and correspond to each other. The relative position of the drawing positioning pen 28 on the composite support plate 9 can be adjusted intuitively by the user. This can achieve eccentric adjustment and positioning in a certain area around the center or center line of the composite support plate 9.

[0041] This utility model also provides a positioning sensor 11 on the clamping table 10, and a trigger plate 12 is provided on the base plate 42 of the positioning support 4 as a triggering device. The positioning sensor 11 is connected to and linked with the turntable drive motor 6. When the trigger plate 12 provided on the positioning support 4 triggers the positioning sensor 11, it controls whether the turntable drive motor 6 is driven or not.

[0042] In this invention, to improve positioning accuracy when positioning the composite support plate 9, it is necessary to clamp the composite support plate 9 before drawing the lines. At this time, if... Figure 4As shown, a positioning support frame 71 is provided at the bottom of the clamping platform 10, and a vertical positioning cylinder 7 is provided at the top of the positioning support frame 71. A positioning plate 72 is provided on the driving end of the vertical positioning cylinder 7. The operating principle of this utility model is as follows: When the composite support plate 9 moves above the central turntable 5, the turntable drive motor 6 drives the central turntable 5 to rotate. At this time, the rotating component 51 drives the two linkage rods 8 to swing. Since the linkage rods 8 are fixed on the positioning support component 4, they pull the two sets of positioning support components 4 toward the composite support plate 9. Since the clamping platform 10 is provided with a positioning sensor 11, when the trigger piece 12 provided on the positioning support component 4 triggers the positioning sensor 11, the turntable drive motor 6 is controlled to stop driving; the independent drive wheel 3 stops driving the independent conveyor belt 31 to move laterally; the vertical drive cylinder 25 drives the drawing positioning pen 28 to move down as a whole and contact the composite support plate 9. Then the turntable drive motor 6 reverses at a slight angle, which is controlled between 0.2 and 0.4 degrees. The purpose is to prevent the positioning squeezing wheel 45 from pressing the composite support plate 9, so that the composite support plate 9 can continue to move under the drive of the independent conveyor belt 31. The independent drive wheel 3 starts to drive the independent conveyor belt 31 to move laterally. The independent conveyor belt 31 drives the composite support plate 9 to move at the bottom of the drawing positioning pen 28 to achieve drawing positioning.

[0043] In summary, this utility model has an independent conveyor belt 31 on the upper part of the clamping table. This independent conveyor belt 31 is connected to the board production equipment or cutting equipment to realize the docking of the production line. When the composite support plate is supported by the independent conveyor belt 31, the positioning support members on the front and rear sides of the central turntable can be used to simultaneously realize the clamping and positioning of the composite support plate 9. This positioning method can improve the clamping accuracy and clamping efficiency. This utility model also has a line drawing positioning pen 28 set above the central turntable 5 to realize the eccentric positioning of the center or a certain area around the center line.

[0044] This invention avoids the inefficiency and low precision of manual drawing. By using automated equipment in conjunction with the production line, it achieves the drawing of lines or dots, overcoming the drawbacks of existing technologies. It is an ideal positioning device for the center through hole of aerospace composite support plates.
