[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1 to 4 The precision positioning device for aerospace components shown includes a bracket 1, which consists of two vertically placed and parallel support plates. Multiple crossbeams are fixedly arranged between the two support plates, arranged in a horizontal row, with each crossbeam perpendicular to both support plates. Each support plate has a support leg fixedly installed at its bottom for stable support.

[0024] A conveyor belt 4, capable of cyclic movement and with both the upper and lower belts moving horizontally, is installed between two support plates via rollers 3. Several rollers 3 are arranged, all parallel to the crossbeam. The rollers 3 are evenly spaced horizontally, and each roller 3 is rotatably connected to both support plates. All rollers 3 are driven into the conveyor belt 4.

[0025] A motor 2 is fixedly mounted on one of the support plates, and the output shaft of the motor 2 is coaxially fixed to one of the roller shafts 3 located at the end of the arrangement. It should be noted that, in order to ensure that the conveyor belt 4 does not bend due to gravity during the conveying process, a flat plate fixed to the two support plates can be set inside the conveyor belt 4, so that the inner wall of the conveyor belt 4 slides in contact with the upper and lower end surfaces of the flat plate.

[0026] Multiple mounting plates 5 are fixedly installed on the outer arm of the conveyor belt 4, and the mounting plates 5 are evenly distributed along the contour of the conveyor belt 4. A support shaft 6 is fixedly installed on each mounting plate 5, and each support shaft 6 is perpendicular to the conveyor belt 4.

[0027] Each support shaft 6 has a machining plate 15 fixedly mounted at its end furthest from the mounting plate 5, parallel to the mounting plate 5. The machining plate 15 is used to support the aerospace parts to be processed. The following description uses one machining plate 15 as an example; the other machining plates 15 are the same.

[0028] Four clamping plates 14 are slidably mounted on the end face of the processing plate 15 away from the mounting plate 5, and the four clamping plates 14 are evenly distributed along the circumference of the support shaft 6.

[0029] Four fixing plates 17 are fixedly installed on the processing plate 15, and four clamping plates 14 are located between the four fixing plates 17. The four clamping plates 14 correspond one-to-one with the four fixing plates 17.

[0030] A spring 18 is fixedly installed between each clamping plate 14 and the corresponding fixing plate 17 to provide clamping force for clamping aerospace components.

[0031] A linkage mechanism is installed between the processing plate 15 and the bracket 1 to drive the four clamping plates 14 to slide synchronously away from the support shaft 6 along the radial direction.

[0032] Specifically, the linkage mechanism includes a turntable 11, which is rotatably mounted on the support shaft 6 and located between the processing plate 15 and the mounting plate 5. Four inclined transmission grooves 12 are formed on the turntable 11, which are evenly distributed along the circumference of the support shaft 6 and correspond one-to-one with the four clamping plates 14.

[0033] Each transmission slot 12 contains a transmission shaft 13 parallel to the support shaft 6, which is slidably mounted within it. The turntable 11 abuts against each transmission shaft 13 in a transmission engagement. Each transmission shaft 13 passes through the processing plate 15 and is fixedly connected to the clamping plate 14 corresponding to its respective transmission slot 12. The processing plate 15 has a clearance groove 16 for the transmission shaft 13 to slide. The clearance groove 16 passes through the processing plate 15 along the axial direction of the support shaft 6 and is also arranged along the radial direction of the support shaft 6.

[0034] A drive assembly for rotating the turntable 11 is provided between the turntable 11 and the support 1.

[0035] Specifically, the linkage component includes a gear 8. A rotating tube 7 is rotatably mounted on the support shaft 6. The rotating tube 7 is fixedly connected to the turntable 11 and also rotatably connected to the mounting plate 5. The gear 8 is fixedly mounted on the rotating tube 7, and a first rack 9 and a second rack 10 that mesh with the gear 8 are fixed on the bracket 1.

[0036] The first rack 9 is located above the conveyor belt 4 and at the starting end of the upper belt.

[0037] The second rack 10 is located below the conveyor belt 4 and at the starting end of the lower belt.

[0038] The first rack 9 and the second rack 10 are located on the same support plate.

[0039] A collection box 19 is provided below the conveyor belt 4, with the opening of the collection box 19 facing upward and corresponding to the second rack 10.

[0040] Working principle: Taking one of the processing plates 15 as an example, when the conveyor belt 4 is conveying, the gear 8 contacts and meshes with the first rack 9, and the first rack 9 pushes the gear 8 to rotate. The gear 8 drives the rotating tube 7 to rotate, and the rotating tube 7 drives the turntable 11 to rotate. The turntable 11 pushes the four drive shafts 13 to move away from the support shaft 6 synchronously. The four drive shafts 13 drive the connected clamping plates 14 away from the support shaft 6 and compress the corresponding springs 18.

[0041] When the space between the four clamping plates 14 is sufficient to accommodate the aerospace component, the aerospace component is placed on the processing plate 15. The placement process can be performed manually or by a robotic arm, which is existing technology and will not be described in detail here.

[0042] After placement, gear 8 disengages from the first rack 9. Under the elastic force of spring 18, the four clamping plates 14 slide close to the support shaft 6 and position and clamp the aerospace component. During this process, the four clamping plates 14 drive the connected drive shaft 13 to move synchronously, the four drive shafts 13 push the turntable 11 to reverse, the turntable 11 drives the rotating tube 7 to reverse, and the rotating tube 7 drives the gear 8 to reverse.

[0043] Subsequently, the processing plate 15 carries the aerospace components to the processing area via four clamps 14 for processing operations. In this embodiment, the processing operations specifically refer to the quality inspection or measurement process.

[0044] After processing, the conveyor belt 4 continues to transport the aerospace components, and the processing plate 15 moves the aerospace components above the collection box 19 via four clamping plates 14. During this process, the gear 8 contacts and meshes with the second rack 10, the four clamping plates 14 move away from the support shaft 6 and release their grip on the aerospace components, which then fall into the collection box 19 under the influence of gravity. To prevent the aerospace components from being bumped or knocked, rubber pads can be fixedly laid on the inner wall of the collection box 19, and the aerospace components can be removed from the collection box 19 in a timely manner by manual labor or a robotic arm.

[0045] Afterwards, gear 8 disengages from the second rack 10, and under the elastic force of spring 18, the four clamps 14 slide back.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
