[0027] The reset plate 43 has the effect that when the stop block 47 contacts the reset plate 43 and compresses the spring 44, after the processed skin is adsorbed and hoisted by the hydraulic cylinder 17, the reset plate 43 drives the stop block 47 at the highest point to move downward under the elastic force of the spring 44, and then the other connecting cylinders 410 are driven to move downward by the negative pressure and the skin itself, so as to reduce the height of the skin from the ground, and reduce the stroke of the hydraulic cylinder 17 when the skin is placed, thereby saving time.

In the actual use and testing process, the connecting rod 335 should be left in the rectangular frame 332 as much as possible to increase the number of measuring points of the skin curvature and make the result more accurate; when detecting different curvature skins,

[0033] The limiting device 2 comprises an elastic telescopic rod 21, a connecting piece 23 of a telescopic rod 22; the upper end of the elastic telescopic rod 21 is fixedly connected with the telescopic rod 22, and the lower end of the elastic telescopic rod 21 is fixedly connected to the upper end of the sliding block 14; the top end side of the telescopic rod 22 is fixedly connected with the connecting piece 23 in sliding fit with the annular groove 35.

[0034] A method of using an auxiliary device for machining aerospace tooling, the method comprising the following steps:

[0035] Step 1: Start the hydraulic cylinder 17 to move the adsorption device 4 downward, so that the rubber suction cup 48 is close to the upper end of the workpiece;

[0036] Step 2: Start the air pump 42 to adsorb the workpiece using negative pressure;

[0037] Step 3: Start motor II16, move the workpiece to the predetermined position, and then turn off air pump 42 to place the workpiece in the predetermined position.

[0038] The working principle of this invention is as follows: When using this device, adjust the inspection device 33, and adjust multiple limiting blocks 334 according to the curvature of the skin after processing. Unused connecting rods 335 are pushed into the T-shaped groove 36 through the gap 331 and rectangular hole 3310. The connecting rods 335 located at the lower end of the limiting block 334 within the rectangular frame 332 are ordered from one end to the other as long, short, long. Then, push the limiting block 334 to adjust the distance between the corresponding connecting rods 335, so that the line connecting the lowest points of the balls 336 at the lower ends of all connecting rods 335 is the same as the curvature of the processed skin (e.g., ...). Figure 6 (As shown by the dotted line) After adjustment, the upper baffle 333 is installed inside the rectangular frame 332 and located at the upper end of the limiting block 334. Then, it is connected to the limiting rod 337 by bolts, so that the upper baffle 333 and the limiting rod 337 clamp the limiting block 334 to prevent it from moving.

[0039] Then the motor II 16 is started to drive the slider 14 to move through the screw rod 13, and then drive the hydraulic cylinder 17 to move to the predetermined position, so that the formed skin is located below the rubber suction cup 48 and the ball 336. Then the hydraulic cylinder 17 is started to drive the suction device 4 and the reset device 3 to move downward, so that the rubber suction cup 48 located in the middle position is tightly attached to the upper end of the highest point of the formed skin. Then the suction device 4 is continuously driven by the hydraulic cylinder 17 to move downward, so that the remaining rubber suction cups 48 are gradually tightly attached to the upper end of the skin. Then the outer shell 41 is continuously moved downward, the rubber suction cup 48 drives the conical barrel 49 and the connecting cylinder 410 to move upward relative to the outer shell 41, and then the air hole 411 is communicated with the inside of the outer shell 41 through the sliding groove I 46. Then the air pump 42 is started to pump out the gas in the outer shell 41, and then the gas in the connecting cylinder 410, the conical barrel 49 and the rubber suction cup 48 is pumped out through the air hole 411, so that the negative pressure is formed to suck the formed workpiece. While the suction device 4 moves downward, the movable plate 31 also moves downward under the action of gravity, and drives the telescopic rod 22 and the elastic telescopic rod 21 to contract through the connecting piece 23, until the ball 336 contacts the upper end surface of the skin. At this time, the workers can check whether the ball 336 contacts the arc surface of the upper end of the skin. If there is a position not contacted together, the position can be marked for subsequent inspection after the transportation is completed, so as to save the inspection time of the workers and improve the work efficiency.

[0040] After the suction, the hydraulic cylinder 17 is started to drive the suction device 4 to move upward to a proper height, so that it is separated from the processing position. Then the motor II 16 is started to drive the slider 14 and the hydraulic cylinder 17 to move to the predetermined position. After the formed skin is moved to the lowest point by the hydraulic cylinder 17, the air pump 42 is closed to restore the normal pressure, so that the skin is separated from the rubber suction cup 48.

[0041] Then the hydraulic cylinder 17 is started again to drive the outer shell 41 to move upward. Since the outer shell 41 is in interference fit with the connecting cylinder 410, the outer shell 41 drives the conical barrel 49 to move upward, and then drives the movable plate 31 to move upward through the conical barrel 49. The movable plate 31 drives the connecting piece 23 to move upward through the annular groove 35, and then drives the telescopic rod 22 and the elastic telescopic rod 21 to stretch. When both of them are stretched to the maximum length, the movable plate 31 is limited to move upward by the connecting piece 23 and the annular groove 35. When the outer shell 41 continues to move upward, the conical barrel 49 contacts the lower end surface of the movable plate 31. The movable plate 31 limits the upward movement of the conical barrel 49, and then limits the upward movement of the connecting cylinder 410, so that the outer shell 41 moves upward relative to the connecting cylinder 410, and then the stop block 47 at the top end of the connecting cylinder 410 contacts the inner bottom surface of the outer shell 41, so that the air hole 411 is resealed, and the reset operation is completed.

[0042] During the resetting process, the motor II 16 drives the adsorption device 4 to move to the upper end of the unprocessed skin, and the hydraulic cylinder 17 drives the adsorption device 4 to move downward. Because of the resetting, all the rubber suction cups 48 are at the same lowest point and can contact the skin. At the same time, the shell 41 is continuously moved downward, so that the air hole 411 is reconnected with the inside of the shell 41. Through the air pump 42, the gas is extracted to adsorb the unprocessed skin. In the process of moving downward, the ball 336 at the lower end of the longest connecting rod 335 contacts the upper end surface of the unprocessed skin. Because it cannot move downward any more, when the adsorption device 4 continues to move downward, the ball 336 at the lowest point supports the corresponding connecting rod 335, limit block 334 and upper baffle 333 to keep the height unchanged, and then drives the rectangular frame 332 to drive the connecting plate 339 to move upward, so that the multi-stage telescopic rod 37 is stretched, ensuring that the inspection device 33 does not affect the adsorption of the unprocessed skin. After the unprocessed skin is placed in the processing position by the above method, the rubber suction cup 48 is moved to the original position for subsequent transportation of the skin.
