Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0015] like Figure 1 and 2 As shown, a novel cabin assembly jig includes a jig 1, a front-end locator 3, a second-frame clamping plate assembly 4, a third-frame clamping plate assembly 5, and a fourth-frame rear-end locator 6. The jig 1 has a front support column 9 and a rear support column 11 at its front and rear ends, respectively. The front-end locator 3 is fixedly mounted on a fixed base 10. A movable base 12 is mounted on the rear support column 11. The fourth-frame rear-end locator 6 is mounted on the movable base 12. A main frame 2 is installed between the front support column 9 and the rear support column 11. The second-frame clamping plate assembly 4 and the third-frame clamping plate assembly 5 are mounted on the main frame 2. A pallet assembly 7 is also installed on the main frame 2 between the third-frame clamping plate assembly 5 and the fourth-frame rear-end locator 6. A hanging joint locator 8 is installed on the main frame 2 between the frame plate assemblies 4 and on the main frame 2 between the second frame plate assembly 4 and the third frame plate assembly 5. A template assembly 13 is installed on the front locator 3 of the first frame. The first frame 16 is fixed to the front locator 3 of the first frame and the template assembly 13 through positioning holes and positioning bolts. The two ends of the second frame 17 are fixed to the template assembly 33 and the second frame plate assembly 4 respectively, and the bottom is positioned and supported by a hanging joint locator 8. The two ends of the third frame 18 are fixed to the second frame plate assembly 4 and the third frame plate assembly 5 respectively, and the bottom is positioned and supported by a hanging joint locator 8. The two ends of the fourth frame 19 are fixed to the third frame plate assembly 5 and the rear locator 6 of the fourth frame respectively.

[0016] Furthermore, both the two-frame clamping plate assembly 4 and the three-frame clamping plate assembly 5 consist of two plates, each 20mm thick. The two-frame clamping plate assembly 4 and the three-frame clamping plate assembly 5 are marked with graduations indicating the edge lines of the parts and the horizontal axis. A threaded locking device is used to position the two plates, ensuring a tight fit according to the cabin's shape. Clamping the lower beam ensures that the central axis of each pair of clamping plate assemblies coincides with the central axes of frames 1 and 4. This ensures that the position of each frame meets the dimensional requirements of the digital model, with a tolerance range of ±0.1mm.

[0017] Furthermore, horizontal lines and axes of symmetry are engraved on the baffles of the front locator of the first frame and the rear locator of the fourth frame, and the center intersection points must be on the same straight line to ensure the coaxiality of the pod. The horizontal reference axis of the pod body is engraved on the front and rear surfaces of each clamping plate to ensure that the axes of the second and third frames coincide with the central axis of the pod body.

[0018] Furthermore, the template assembly 13 is provided with two templates and a bushing auxiliary positioning template. The two templates are used to support the positioning of the cabin joint, and the templates are designed in a U-shape. The bushing auxiliary positioning template is used to press the bushing on the upper beam.

[0019] Furthermore, the lower end of the pallet assembly 7 is connected to the main frame 2 via a threaded structure, and the upper end of the pallet assembly 7 is provided with an arc-shaped support that rests on the bottom of the four frames 19.

[0020] Furthermore, the main beam of the cabin faces downwards along the flight direction, and the position of the main beam on the frame 1 is positioned by the lifting lug holes on the main beam spaced 355.6mm apart. The lifting joint locator 8 is a threaded stepped locating pin, with an M45X2-6h bolt screwed into the lifting lug hole of the main beam at the upper end and inserted into the main frame 2 of the frame 1 at the lower end, which meets the positioning requirements of the basic hole system clearance fit.

[0021] Furthermore, the frame 1 is also equipped with a positioning module 14 for hoisting and positioning the cabin. The positioning module 14 is equipped with multiple positioning bolts that cooperate with the cabin positioning holes for hoisting the cabin.

[0022] Furthermore, the movable seat 12 is composed of a crank, a lead screw, a valve block, and a positioning baffle. The crank is connected to one end of the lead screw, the valve block cooperates with the lead screw, and the positioning baffle is fixedly installed on the valve block. The position of the movable seat 12 is controlled by the crank to facilitate product unloading.

[0023] Furthermore, an elevation pad 15 is installed at each of the four corners of the bottom of the frame 1. The number of elevation pads 15 can be designed to be more as needed. By adjusting the elevation pads 15, the assembly position of the frame 1 is made to be on the same horizontal plane. At the same time, the four elevation pads are required to be equidistant from, parallel to and symmetrical with the axis of the cabin. The heading should be marked on the frame 1.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
