[0027] An operating sliding platform 101 is fixed on the adjusting support platform 102, and both the operating sliding platform 101 and the adjusting support platform 102 are fixed on the supporting leg frame 108, wherein a lifting motor 110 is arranged under the adjusting support platform 102, and the lifting motor 110 is fixed on the corresponding supporting leg frame 108, and the output shaft of the lifting motor 110 is fixedly matched with one of the adjusting support screw columns 103; a plurality of locking screws 111 are installed with horizontal threads along the width direction on the side edge of the operating sliding platform 101, which are used to fix the sliding base plate 118 slidably installed on the operating sliding platform 101 to different positions. A rib support table 120 is fixed on the sliding base plate 118 by means of a plurality of bracket rods 119, a plurality of ribs 122 for supporting arc-shaped plate parts are equidistantly fixed on the upper surface of the rib support table 120, a pull-down beam 125 is arranged between two adjacent ribs 122, two symmetrically arranged threaded shafts 124 are fixed on the lower surface of the pull-down beam 125, all the threaded shafts 124 are slidably fitted along the normal direction of the upper surface of the rib support table 120, each threaded shaft 124 located below the rib support table 120 is threadedly sleeved with a threaded sleeve 123, each threaded sleeve 123 is fixed to the output shaft of the corresponding pull-down motor 121, and all the pull-down motors 121 are fixed on the sliding base plate 118. Two clamping plate sliding tables 127 are symmetrically fixed on the pull-down beam 125, and a clamping plate 130 is fixed on each of the two clamping plate sliding tables 127. A clamping movable plate 126 is arranged on the side of the clamping movable plate 130, and the clamping movable plate 126 is slidably arranged on the clamping plate sliding table 127. A clamping guide screw 128 that slides with the clamping movable plate 126 is also fixed on the clamping fixed plate 130. A clamping nut 129 is threadedly sleeved on the clamping guide screw 128 for squeezing the clamping movable plate 126 to move toward the clamping fixed plate 130. The clamping movable plate 126 and the clamping fixed plate 130 are used to clamp and fix the edge position of the arc-shaped plate parts.

[0028] The working principle of a processing device for manufacturing aerospace parts disclosed in the present invention is as follows: an arc-shaped plate part (such as the outer contour skin of an aircraft) is stamped and bent and then placed on a bracket formed by multiple ribs 122, and then its edge is placed between a clamping fixed plate 130 and a clamping movable plate 126 at corresponding positions, and the clamping nut 129 is rotated. The clamping nut 129 rotates on the clamping guide screw 128 to squeeze the clamping movable plate 126, and the clamping movable plate 126 squeezes the arc-shaped plate part, and then the arc-shaped plate part is fixed. It should be noted that in order to prevent the parts from being scratched, a rubber layer needs to be provided on the contact surface between the clamping movable plate 126 and the clamping fixed plate 130 and the parts. Then all the pull-down motors 121 are started, and the output shaft of the pull-down motor 121 drives the threaded sleeve 123 to rotate (a torque sensor and a torque adjustment assembly (which acts as a torque wrench) are also arranged between the output shaft of the pull-down motor 121 and the threaded sleeve 123 to prevent the threaded sleeve 123 from transmitting too much axial tension to the threaded shaft 124). The rotation of the threaded sleeve 123 will drive the threaded shaft 124 to move axially, thereby driving the clamping fixed plate 130 and the clamping movable plate 126 on the pull-down beam plate 125 to move. At this time, the edge of the arc-shaped plate part will be subjected to downward pulling force, so that the arc-shaped plate part fits tightly on the rib plate 122.

[0029] Since the curved plate parts are used on the outer surface of the aircraft, that is, the side in contact with the air, it is necessary to ensure that the surface is smooth and flat enough. After stamping or production, the surface will be slightly uneven, so it needs to be manually polished with sandpaper. The traditional method requires very experienced fitters to touch it with their hands to know where the unevenness is, which results in very low processing efficiency of this work and huge labor costs. At this time, it is only necessary to control the lifting motor 110. The output shaft of the lifting motor 110 drives the two adjusting support screw rods 103 to rotate synchronously through the synchronous transmission belt 109, and then drives the support beam 107 to move. The support beam 107 drives the outer shell cover 117 and the marking assembly to move toward the arc-shaped plate part, so that the contact rod 132 contacts the surface of the arc-shaped plate part. Since the distance between the part fixed to the outer shell cover 117 and the arc-shaped plate part is known (because the moving distance of the outer shell cover 117 is known), if a certain position of the arc-shaped plate part is raised compared to other positions, the contact rod 132 will be displaced relative to other contact rods 132. At this time, the tension spring 140 is stretched, and the sliding reflector 139 is aligned with the light receiving unit. When the distance between the sliding reflector 139 and the light receiving unit 138 changes, since the light emitted by the laser 137 will be reflected on the light receiving unit 138, when the distance between the sliding reflector 139 and the light receiving unit 138 changes, it can be detected by the light receiving unit 138 (the light receiving unit 138 has a light sensor inside, and the pixel position of the light sensor is fixed. Therefore, when the position of the laser 137 reflected on the sensor by the sliding reflector 139 changes, it will cause the pixels at different positions to be received by the pipeline. Therefore, the pixel points can be used as scales to judge the displacement of the sliding reflector 139, and thus the displacement of the contact rod 132) The convex amount of the surface of the arc-shaped plate part (conversely, the concave amount). At this time, the electromagnetic coil embedded on the inner wall of the starting position contact sliding cylinder 133 generates magnetic force to push the marking pen shaft 135 to pop out from the marking pen shaft placement channel 141 (when the electromagnetic coil has no electricity, the marking pen shaft 135 itself also has magnetic force, and the top of the marking pen shaft 135 will be attracted to the top of the contact sliding cylinder 133, and then shrink into the marking pen shaft placement channel 141), and then mark a point on the surface of the arc-shaped plate part (the end of the marking pen shaft 135 that contacts the part surface is made of soft material and can absorb ink, such as a mark pen tip), and the operator can then grind the point to eliminate the raised point (repeated operations are required).

[0030] The specific operation steps are as follows: the output shaft of the adjusting driving gear 105 is controlled to drive the adjusting active gear 104 to rotate, the adjusting active gear 104 drives the adjusting toothed disc 106 to rotate, the adjusting toothed disc 106 drives the outer shell cover 117 to rotate, thereby driving all the marking components to rotate; by controlling the extension and retraction amount of the telescopic rods of the three universal adjusting electric cylinders 114, the swing angles of the outer shell cover 117 and all the marking components can be controlled, so that the contact rods 132 in all the marking components are in full contact with the arc-shaped plate parts.
