This technical solution has the following problems: 1) The platform swing angle is only between -25° and +25°, which is easy to produce detection blind spots; 2) The installation of the aerospace electronic equipment and sensors to be tested is completed manually, and the level of automation is low. In addition, the Chinese invention patent document with publication number CN 113740926 A discloses a movable surplus detection device, including a front conveyor belt, a rear conveyor belt and a rotating detection mechanism arranged between the front conveyor belt and the rear conveyor belt. The disadvantage of this technical solution is that it is mainly suitable for objects with relatively flat shapes at both ends, and the scope of application is narrow. Utility Model Content

[0029] The rack body 1 is as follows Figure 2 As shown, it includes a base 1-1 at the bottom, a plurality of adjustment block casters 1-2 are installed on the lower surface of the base 1-1, a rack 1-4 extending along the length direction of the base 1-1 is fixed in the middle of the upper part, and linear guide rails 1-3 parallel to the rack 1-4 are fixed on both sides. In addition, guide shafts 1-5 extending along the length direction of the base 1-1 are fixed on both sides of the upper end of the base 1-1. The base 1-1 is equipped with a protective cover, clamping components 4 located near the two ends of the protective cover, and two lifting components 3 spaced apart between the two clamping components 4.

[0030] Protective cover 2 Figure 3 As shown, it includes fixed covers 2-1 fixed at both ends of the base 1-1 in the length direction and a pair of movable covers 2-2 located between the fixed covers at both ends. The bottom of the movable cover 2-2 forms a movable pair with the guide shafts 1-5 on both sides through linear bearings 2-3, and the top is equipped with an electric cylinder 2-4 for driving the opening and closing.

[0031] Lifting assembly 3 Figure 4As shown, the two sides of the bottom plate of the main support 3-1 are respectively fixedly connected to the sliders 3-8 adapted to the corresponding linear guide rails 1-3 to form a moving pair. The middle part of the bottom plate supports the translation motor 3-2 and the lifting motor 3-10. The translation drive motor 3-2 is meshed with the rack 1-4 through the driving gear 3-9 at the reduction output end. The lifting motor 3-10 is connected to the vertical screw 3-3-2 through the worm gear reduction output. The upper part of the main support 3-1 is fixedly connected to two guide sleeves 3-5 distributed at intervals. The two guide sleeves 3-5 are respectively connected to the two guide columns 3-4 supporting the lifting plate 3-6 at the upper end to form a vertical moving pair. The lower ends of the two guide columns 3-4 are respectively fixedly connected to the two sides of the lifting plate 3-3-1 with nuts in the middle. The vertical screw and the nut form a spiral pair. The lifting mechanism 3-3 composed of this can move up and down in the vertical direction within a certain range. In addition, a cable drag chain 3-7 is also installed on one side of the main support 3-1.

[0032] Clamping assembly 4 Figure 5 , 6 As shown in Figures 7 and 8, both sides of the base plate of the clamping box seat 4-1 are respectively fixedly connected with the corresponding linear guide rails 1-3 to form a sliding block 4-3 of a moving pair, and the upper middle part of the base plate supports a horizontal shift motor 4-4, which is engaged with the rack 1-4 through the downward reduction output end drive gear 4-2.

[0033] The upper part of the clamping box seat 4-1 is perforated with a rotating ring gear support 4-15 that can rotate around a horizontal axis and a three-jaw chuck 4-6 fixed thereto. The rotating ring gear support 4-15 is located outside the clamping box seat 4-1 and is meshed with a rotating drive gear 4-5 driven by a rotating drive motor 4-13 placed inside the clamping box seat 4-1. When the clutch 4-11 is in a disengaged state, the three-jaw chuck 4-6 can be driven to rotate as required under the drive of the rotating drive motor 4-13. The three-jaw chuck 4-6 is equipped with three radial clamping jaws 4-6-1 evenly distributed in the circumference, and the inner end face is equipped with an inner end gear disk that can rotate relatively. The gear disk forms a plane spiral pair through its end face spiral and the opposite end face of the clamping jaw 4-6-1.

The inner end gear disk of the three-jaw chuck 4-6 is meshed with the jaw driving gear 4-7 driven by the jaw driving motor 4-12 arranged in the clamping box seat 4-1 through the clutch 4-11 in the engaged state. Therefore, under the drive of the jaw driving motor 4-12, the radial clamping or loosening action of the jaw 4-6-1 can be realized as needed through the planar spiral pair.

[0034] like Figure 7 As shown, the outer end of the clamping jaw 4-6-1 is equipped with a pressure sensor 4-8, and the clamping part thereof is provided with a sensor head 5-1 through a lining plate 4-9 and a buffer pad 4-10.

[0036] Step 1: Open the mobile cover 2-2, place the object to be measured on the lifting assembly 3 that has been lifted to a suitable height, and close the mobile cover 2-2. Drive the left and right clamping assemblies 4 to move toward each other to the specified position, and operate the clamping claws 4-6-1 to clamp the object to be measured.

[0037] Step 2: Operate the left and right clamping components 4 to drive the object to be measured to rotate at a preset speed, causing the excess objects to slide and fall inside the object to be measured to generate vibration, so that the sensor head 5-1 detects and outputs a vibration signal.

[0038] Step 3: The vibration signal output by the sensor head 5-1 is transmitted to the host computer by the signal acquisition and processing unit.

[0039] Step 4: The left and right clamping components 4 drive the object to be measured to stop rotating, the clamping jaws 4-6-1 release the object to be measured, place it on the lifting component 3, open the moving cover 2-2, remove the object to be measured from the lifting component 3, and clean up the excess.

[0040] Step 5. Repeat steps 1 to 4 until all the excess is cleaned up.

[0041] Step 6: Complete the entire testing process.

[0042] In summary, with the help of the redundant object detection device of this embodiment, the automated detection of redundant objects in the propulsion system can be realized, thereby effectively improving the detection accuracy and efficiency and saving manpower.

[0043] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
