Description

Technical Field

[0001] The present application relates to the field of assembly tooling, in particular to an assembly tooling for a cylindrical structure of a test device. Background Art

[0002] The test equipment cylinder is a device. It typically houses various sensors, electronic equipment, and data storage and transmission systems, used to collect and transmit data from the spacecraft in space. During spacecraft assembly, the power generator is integrated with the rear equipment compartment before the test equipment cylinder and the power generator are assembled. The test equipment cylinder is assembled with the power generator using an aligned plug-in connection.

[0003] The existing assembly tooling for the test equipment cylinder structure includes a support fixture, on which the test equipment cylinder structure is placed. During assembly, the support fixture is manually driven and moved toward the power generator until one end of the test equipment cylinder structure is inserted and docked with the integrated power generator-rear equipment compartment. This docking end serves as the insertion end of the test equipment cylinder structure. This insertion end is formed with a chamfer (forming a conical shape) to facilitate insertion of the test equipment cylinder structure into the insertion port of the power generator, thus completing the assembly between the test equipment cylinder structure and the power generator.

[0004] After one end of the test equipment cylinder structure is inserted into the integrated power generator and rear equipment compartment, if the coaxiality between the insertion end of the test equipment cylinder structure and the insertion port on the power generator is not high, the insertion end of the test equipment cylinder structure will get stuck during the insertion process and cannot be fully inserted into the insertion port of the power generator for docking. In this case, it is necessary to manually fine-tune the position of the support fixture so that the insertion end of the test equipment cylinder structure can be fully inserted into the insertion port of the power generator. This will consume a lot of manpower and material resources to fine-tune the position of the test equipment cylinder structure, resulting in reduced assembly efficiency of the test equipment cylinder structure. Summary of the Invention

[0005] In order to improve the assembly efficiency of the cylindrical structure of a test device and reduce the assembly workload, the present application provides an assembly tool for the cylindrical structure of a test device.

[0006] The present application provides an assembly tool for a cylindrical structure of a test device using the following technical solution:

[0007] An assembly tool for a cylindrical structure of a test device, comprising a mounting platform, a moving assembly, a locking assembly, and a fine-tuning assembly;

[0008] The mounting platform includes a lower fixing plate mounted on the moving assembly and an upper fixing plate located above the lower fixing plate, wherein the upper fixing plate is used to place a tray carrying the cylindrical structure of the test equipment;

[0009] The moving assembly is used to drive the installation platform to move horizontally in a direction close to or away from the power generating device;

[0010] The locking assembly is connected to the upper fixing plate and the lower fixing plate and is arranged in multiple numbers at horizontal intervals. When the moving assembly drives the mounting platform to move in a direction close to the power generating device, the locking assembly is used to lock the position of the upper fixing plate;

[0011] The fine-tuning assembly connects the upper fixing plate and the lower fixing plate. When the insertion end of the cylindrical structure of the test equipment is not fully inserted into the insertion port of the power generating device, the position of the upper fixing plate is unlocked. The fine-tuning assembly is used to fine-tune the position of the upper fixing plate. As the mounting platform continues to move, the insertion end of the cylindrical structure of the test equipment is fully inserted into the insertion port of the power generating device.

[0012] By adopting the above technical solution, during assembly, the locking assembly first locks the position of the upper fixing plate relative to the lower fixing plate, and the tray carrying the test equipment cylindrical structure is placed on the upper fixing plate so that the insertion end of the test equipment cylindrical structure corresponds to the insertion port of the generator. Then, the movement drives the mounting platform to slide horizontally in the direction close to the generator, and the insertion end of the test equipment cylindrical structure is inserted into the insertion port of the power generating device. When the insertion end of the test equipment cylindrical structure is not fully inserted into the insertion port of the power generating device (that is, the coaxiality between the insertion end of the test equipment cylindrical structure and the insertion port of the generator is not high), the locking assembly unlocks the position of the upper fixing plate. As the moving assembly continues to drive the mounting platform closer to the power generating device, the fine-tuning assembly fine-adjusts the position of the upper fixing plate so that the insertion end of the test equipment cylindrical structure is aligned with the insertion port of the generator until the insertion end of the test equipment cylindrical structure is fully inserted into the insertion port of the generator, thereby completing the assembly of the test equipment cylindrical structure. Compared with the prior art method that requires pausing the assembly to manually adjust the position of the test equipment cylindrical structure, the present application can achieve fine-tuning of the position of the test equipment cylindrical structure during the assembly process, thereby improving the assembly efficiency of the test equipment cylindrical structure and reducing the assembly workload.

[0013] Optionally, the moving assembly includes a moving track, a linear module and a force sensor;

[0014] The movable track is arranged horizontally and one end of the movable track is directly opposite to the insertion port of the power generating device. The linear module is slidably mounted on the movable track. The lower fixed plate is mounted on the linear module. The linear module is used to drive the lower fixed plate to slide horizontally on the track. The force sensor is electrically connected to the locking assembly and the linear module. The force sensor is mounted on the linear module and is used to sense the resistance when the insertion end of the cylindrical structure of the test equipment is inserted into the insertion port of the power generating device.

[0015] When the force sensor senses that the resistance reaches a preset value, the linear module stops driving the lower fixed plate to slide; when the force sensor senses that the resistance does not reach the preset value, the locking assembly unlocks the position of the upper fixed plate.

[0016] By adopting the above technical solution, the force sensor can accurately determine whether the insertion end of the test equipment cylindrical structure is fully inserted into the insertion port of the generator. When the insertion end of the test equipment cylindrical structure is fully inserted into the insertion port of the generator, the resistance sensed by the force sensor reaches a preset value. At this time, the linear module stops driving the lower fixed plate to slide, and the assembly of the test equipment cylindrical structure is completed. When the resistance sensed by the force sensor does not reach the preset value, that is, the insertion end of the test equipment cylindrical structure is not fully inserted into the insertion port of the power generator, the locking assembly immediately unlocks the upper fixed plate. At this time, the lower fixed plate is still sliding in the direction close to the power generator. The fine-tuning assembly fine-tunes the position of the insertion end of the test equipment cylindrical structure so that the insertion end of the test equipment cylindrical structure is fully inserted into the insertion port of the power generator.

[0017] Optionally, the locking assembly includes a guide post, a locking slide, a driving member and a locking member;

[0018] The guide column is arranged vertically and its bottom end is fixed to the upper end surface of the lower fixed plate. The top end of the guide column is located below the upper fixed plate. The locking slide is slidably connected to the guide column along the axis direction of the guide column. The driving member is connected to the locking slide and is used to control the lifting of the locking slide. The locking member connects the locking slide and the upper fixed plate.

[0019] When the locking slide is raised, the locking member is used to lock the horizontal position of the upper fixing plate, and when the locking slide is lowered, the position of the upper fixing plate is unlocked.

[0020] By adopting the above technical solution, the guide column can limit the lifting position of the locking slide. When the upper fixing plate needs to be locked, the driving member drives the locking slide to rise, thereby locking the upper fixing plate through the locking member. When the upper fixing plate needs to be unlocked, the driving member drives the locking slide to descend, thereby unlocking the upper fixing plate.

[0021] Optionally, the locking member includes a locking sleeve and a locking shaft;

[0022] The locking sleeve is installed on the upper end surface of the locking slide, the locking shaft is arranged vertically and the top end is installed on the upper fixed plate, the locking sleeve is vertically provided with a locking groove for the coaxial insertion of the locking shaft, the peripheral wall of the locking shaft is provided with a first conical surface, the first conical surface is inclined from top to bottom along the axial direction close to the locking shaft, and the groove wall of the locking groove is provided with a second conical surface arranged parallel to the first conical surface.

[0023] By adopting this technical solution, when the locking slide abuts the lower fixing plate, the first tapered surface does not contact the second tapered surface, leaving a gap between the locking shaft and the wall of the locking slot, allowing for subsequent fine-tuning of the upper fixing plate's position. When the locking slide rises, the first tapered surface abuts the second tapered surface, locking the upper fixing plate in place and preventing horizontal movement of the upper fixing plate.

[0024] Optionally, the driving member includes a wedge-shaped slider, a guide rail and a driving cylinder;

[0025] The wedge-shaped slider slides horizontally on the upper end surface of the lower fixed plate in a direction approaching or moving away from the locking slider, the guide rail is arranged along the sliding direction of the wedge slider, the guide rail is mounted on the lower fixed plate and is slidably connected to the wedge slider, the driving cylinder is mounted on the lower fixed plate and the output shaft is arranged along the sliding direction parallel to the wedge slider, and the output shaft of the driving cylinder is connected to the wedge slider;

[0026] The side of the wedge-shaped slider facing the locking slider is a third conical surface inclined from bottom to top in a direction away from the locking slider, and the side of the locking slider facing the wedge-shaped slider is a fourth conical surface arranged parallel to the third conical surface.

[0027] By adopting the above technical solution, when the locking slide rises, the driving cylinder drives the wedge-shaped slider to slide in a direction close to the locking slide, and the third tapered surface and the fourth tapered surface abut against each other, pushing the locking slide up. When the driving cylinder drives the wedge-shaped slider to slide in a direction away from the locking slide, the locking slide descends.

[0028] Optionally, the fine-tuning assembly is located between the lower fixing plate and the upper fixing plate and is connected to the centers of the upper fixing plate and the lower fixing plate, and a plurality of locking assemblies are arranged around the fine-tuning assembly.

[0029] By adopting the above technical solution, multiple locking assemblies jointly limit the position of the upper fixed plate, and the fine-tuning assembly is located between the multiple locking assemblies, so that the upper fixed plate is subjected to more uniform force and moves more smoothly during fine-tuning.

[0030] Optionally, the fine-tuning assembly includes a bull's eye bearing, a cover plate, and a fine-tuning slider;

[0031] The bull's eye bearing is installed on the upper end surface of the lower fixed plate and is provided in plurality. The cover plate is horizontally covered on the plurality of bull's eye bearings. The fine-tuning slider is installed on the lower end surface of the upper fixed plate. The bottom end of the fine-tuning slider is hemispherical and abuts against the upper end surface of the cover plate.

[0032] By adopting the above technical solution, after the upper fixing plate is unlocked, as the mounting platform continues to move toward the power generator, the resistance between the wall of the power generator insertion hole and the insertion end of the test equipment cylindrical structure is transferred to the upper fixing plate, causing the upper fixing plate to move slightly. The fine-tuning slider moves on the cover plate along with the upper fixing plate, causing the cover plate to move horizontally on the bull's eye bearing, supporting the upper fixing plate while reducing the resistance to its movement. Subsequently, as the mounting platform moves, the insertion end of the test equipment cylindrical structure is fully inserted into the insertion hole of the power generator.

[0033] Optionally, the number of the bull's eye bearings is the same as the number of the locking assemblies, and the bull's eye bearings and the locking assemblies are arranged in a one-to-one correspondence.

[0034] By adopting the above technical solution, multiple locking assemblies impose multiple directional restrictions on the position of the upper fixing plate. When the position of the upper fixing plate is fine-tuned, the position of the bull's eye bearing corresponds to the position of the locking assembly, thereby balancing the force on the upper fixing plate, so that the upper fixing plate can accurately adjust its own position according to the resistance between the insertion end of the cylindrical structure of the test equipment and the hole wall of the insertion hole of the power generating device.

[0035] Optionally, the lower end surface of the cover plate is coaxially connected with an anti-slip ring, and the plurality of bull's eye bearings are all located in the anti-slip ring.

[0036] By adopting the above technical solution, the anti-slip ring can prevent the cover plate from sliding off the bull's eye bearing, thereby improving the structural stability of the fine-tuning component.

[0037] Optionally, the upper end surface of the upper fixing plate is provided with a limiting column for plugging into a tray carrying the cylindrical structure of the testing equipment, and a plurality of the limiting columns are arranged at horizontal intervals.

[0038] By adopting the above technical solution, when the pallet carrying the cylindrical structure of the test equipment is placed on the upper fixed plate, the position of the pallet is limited by plugging the limiting columns into the pallet, thereby limiting the position of the cylindrical structure of the test equipment.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. When the insertion end of the test equipment cylinder structure is not fully inserted into the insertion port of the power generator, the locking assembly unlocks the position of the upper fixing plate, the mounting platform continues to move closer to the power generator, and the fine-tuning assembly fine-adjusts the position of the upper fixing plate so that the insertion end of the test equipment cylinder structure is aligned with the insertion port of the generator until the insertion end of the test equipment cylinder structure is fully inserted into the insertion port of the generator, thereby improving the assembly efficiency of the test equipment cylinder structure and reducing the assembly workload;

[0041] 2. When the locking slide abuts the lower fixed plate, the first conical surface does not contact the second conical surface, and there is a gap between the locking shaft and the wall of the locking slot, which allows for fine-tuning of the upper fixed plate position. When the locking slide rises, the first conical surface abuts the second conical surface, thereby locking the upper fixed plate position.

[0042] 3. After the position of the upper fixing plate is unlocked, as the mounting platform continues to move toward the power generator, the resistance between the hole wall of the power generator insertion hole and the insertion end of the test equipment cylindrical structure is transferred to the upper fixing plate, causing the position of the upper fixing plate to move slightly. As the mounting platform moves, the insertion end of the test equipment cylindrical structure is fully inserted into the insertion hole of the power generator. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] The following is combined with Figure 1-4 This application is described in further detail.

[0050] The embodiment of the present application discloses an assembly tool for a cylindrical structure of a testing device.

[0051] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0052] Reference Figure 1 and Figure 2 The assembly tooling of the cylinder structure of the test equipment includes an installation platform 1, a moving component 2, a locking component 3 and a fine-tuning component 4.

[0053] The mounting platform 1 includes a lower fixed plate 11 and an upper fixed plate 12 located above the lower fixed plate 11. The locking assembly 3 and the fine-tuning assembly 4 are both located between the upper fixed plate 12 and the lower fixed plate 11. The upper fixed plate 12 and the lower fixed plate 11 can be connected by the locking assembly 3 and the fine-tuning assembly 4. A plurality of limit posts 5 are fixedly connected to the upper end surface of the upper fixed plate 12 at horizontal intervals to facilitate insertion with the tray 6 carrying the cylindrical structure of the test equipment, thereby limiting the horizontal position of the tray 6 carrying the cylindrical structure of the test equipment. The lower fixed plate 11 is mounted and fixed to the moving assembly 2.

[0054] During assembly, the moving assembly 2 is installed on one side of the power generating device and the moving assembly 2 can drive the mounting platform 1 to slide horizontally in the direction close to the power generating device. Therefore, before assembly, the tray 6 carrying the cylindrical structure of the test equipment needs to be placed on the upper fixed plate 12. The locking assembly 3 can lock the position of the upper fixed plate 12 relative to the lower fixed plate 11 so that the upper fixed plate 12 cannot shake at will. At this time, the insertion end of the cylindrical structure of the test equipment corresponds to the insertion port of the power generating device. Afterwards, the lower fixed plate 11 is driven by the moving assembly 2 to move in the direction close to the power generating device, and the insertion end of the cylindrical structure of the test equipment approaches and is inserted into the insertion port of the power generating device.

[0055] If the insertion port of the power generating device and the insertion end of the test equipment's cylindrical structure are not highly coaxial (i.e., the insertion end is inserted into the insertion port but not fully), the locking assembly 3 unlocks the position of the upper fixing plate 12, and the fine-tuning assembly 4 allows the upper fixing plate 12 to swing horizontally above the lower fixing plate 11 within a certain range. The range of horizontal swing of the upper fixing plate 12 is the fine-tuning range.

[0056] Because the cylindrical structures of the power generator and test equipment are relatively complex and vary from model to model, they are not shown in the drawings for the sake of simplicity. However, the structures connected to the cylindrical structures of the power generator and test equipment, including the rails and tray 6, are shown in the drawings.

[0057] As the lower fixing plate 11 continues to move toward the power generator, the resistance between the hole wall of the power generator insertion port and the insertion end of the test equipment cylinder structure guides the upper fixing plate 12 to be fine-tuned, and the position of the test equipment cylinder structure is fine-tuned accordingly, until the insertion end of the test equipment cylinder structure is fully inserted into the insertion port of the power generator. In this way, the position of the test equipment cylinder structure can be fine-tuned without manual intervention, improving the assembly efficiency of the test equipment cylinder structure and reducing the assembly workload.

[0058] To improve the uniformity of force applied to the upper fixing plate 12, multiple locking assemblies 3 are provided, arranged around the fine-tuning assembly 4. The fine-tuning assembly 4 connects to the center of the upper fixing plate 12 and the lower fixing plate 11. As shown in the figure, this application uses four locking assemblies 3 as an example. The optimal number of locking assemblies 3 is four to maximize the stability of the force applied to the upper fixing plate 12. The fine-tuning assembly 4 is located in the center, ensuring that the upper fixing plate 12 remains stable as much as possible when adjusting its position.

[0059] Reference Figure 1 The moving component 2 includes a moving track 21 , a linear module 22 and a force sensor 23 .

[0060] The movable track 21 is horizontally arranged, with one end facing the insertion port of the power generator. A linear module 22 is slidably mounted on the movable track 21. The lower fixed plate 11 is mounted on the linear module 22, and the linear module 22 drives the lower fixed plate 11 to slide horizontally along the track. A force sensor 23 is mounted on the linear module 22 and electrically connected to the locking assembly 3 and the linear module 22. The force sensor 23 senses the resistance when the insertion end of the test equipment's cylindrical structure is inserted into the insertion port of the power generator.

[0061] When the force sensor 23 senses that the resistance reaches a preset value, it indicates that the insertion end of the cylindrical structure of the testing equipment is completely inserted into the insertion port of the power generating device. At this time, the linear module 22 stops driving the lower fixed plate 11 to slide, and the assembly is completed.

[0062] When the force sensor 23 senses that the resistance has not reached the preset value, the locking assembly 3 unlocks the position of the upper fixed plate 12, so that the fine-tuning assembly 4 provides a fine-tuning range for the upper fixed plate 12, so that the upper fixed plate 12 continues to move along with the lower fixed plate 11 in the direction close to the power generating device to adjust its own angle until the insertion end of the cylindrical structure of the test equipment is completely inserted into the insertion port of the power generating device.

[0063] Reference Figure 2 and Figure 3 The locking assembly 3 includes a guide column 31 , a locking slide 32 , a driving member 33 and a locking member 34 .

[0064] Among them, the guide column 31 is arranged vertically and the bottom end is fixed to the upper end surface of the lower fixed plate 11, the top of the guide column 31 is located below the upper fixed plate 12, the locking slide 32 is slidably connected to the guide column 31 along the axial direction of the guide column 31, the driving member 33 is connected to the locking slide 32 and is used to control the lifting and lowering of the locking slide 32, and the locking member 34 connects the locking slide 32 and the upper fixed plate 12.

[0065] In addition, the locking member 34 includes a locking sleeve 341 and a locking shaft 342. The locking sleeve 341 is mounted on the upper end surface of the locking slide 32, and the locking shaft 342 is arranged vertically and its top end is mounted on the upper fixed plate 12. The locking sleeve 341 is vertically provided with a locking groove 343 for the coaxial insertion of the locking shaft 342. The peripheral wall of the locking shaft 342 is provided with a first tapered surface 344, which is arranged obliquely from top to bottom along the axis direction close to the locking shaft 342. The groove wall of the locking groove 343 is provided with a second tapered surface 345 arranged parallel to the first tapered surface 344.

[0066] In order to prevent the locking slide 32 from interfering with the locking shaft 342 when the locking slide 32 is raised or lowered, as shown in the figure, a connecting groove 321 for the locking shaft 342 to be inserted is formed on the locking slide 32 .

[0067] In addition, if Figure 2 and Figure 4 As shown, the driving member 33 includes a wedge-shaped slider 331 , a guide rail 332 and a driving cylinder 333 .

[0068] The wedge-shaped slider 331 slides horizontally on the upper end surface of the lower fixed plate 11 in a direction toward or away from the locking slider 32. The guide rail 332 is mounted on the lower fixed plate 11 and is slidably connected to the wedge-shaped slider 331. The drive cylinder 333 is mounted on the lower fixed plate 11, and its output shaft is arranged parallel to the sliding direction of the wedge-shaped slider 331. The output shaft of the drive cylinder 333 is connected to the wedge-shaped slider 331. The side of the wedge-shaped slider 331 facing the locking slider 32 has a third tapered surface 334 that is inclined from bottom to top and away from the locking slider 32. The side of the locking slider 32 facing the wedge-shaped slider 331 has a fourth tapered surface 335 that is arranged parallel to the third tapered surface 334.

[0069] When the driving cylinder 333 drives the wedge-shaped slider 331 to slide in the direction close to the locking slider 32, the third conical surface 334 and the fourth conical surface 335 fit together and push the locking slider 32 to rise until the first conical surface 344 and the second conical surface 345 abut against each other, thereby locking the position of the upper fixing plate 12 to prevent the upper fixing plate 12 from shaking horizontally.

[0070] When the driving cylinder 333 drives the wedge-shaped slider 331 to slide in the direction away from the locking slide 32, the third conical surface 334 moves away from the fourth conical surface 335, the locking slide 32 descends, the first conical surface 344 does not contact the second conical surface 345, and there is a gap between the locking shaft 342 and the groove wall of the locking groove 343, so as to reserve a fine-tuning distance for subsequent fine-tuning of the position of the upper fixing plate 12, thereby unlocking the upper fixing plate 12.

[0071] In order to simplify the structure of the locking assembly 3 and improve the synchronization of multiple locking assemblies 3, as shown in FIG. Figure 4 As shown, the wedge-shaped sliders 331 in multiple locking assemblies 3 are all connected to the same drive cylinder 333. The drive cylinder 333 is connected to a linkage member 7, which includes a connecting plate 71 and a connecting rod 72. The connecting plate 71 is mounted on the output shaft of the drive cylinder 333 and connects to two wedge-shaped sliders 331 in the same row. Two connecting rods 72 are provided, and their ends are respectively connected to two wedge-shaped sliders 331 in the same row. Thus, two connecting rods 72 and one connecting plate 71 connect four wedge-shaped sliders 331, thereby achieving the effect of multiple locking assemblies 3 working together.

[0072] Reference Figure 3 and Figure 4 The fine-tuning assembly 4 includes a bull's eye bearing 41 , a cover plate 42 and a fine-tuning slider 43 .

[0073] Multiple bull's-eye bearings 41 are mounted on the upper end surface of the lower fixed plate 11. The number of bull's-eye bearings 41 is the same as the number of locking assemblies 3, and the bull's-eye bearings 41 and locking assemblies 3 are arranged one-to-one. A cover plate 42 is horizontally mounted over the multiple bull's-eye bearings 41. An anti-slip ring 44 is coaxially connected to the lower end surface of the cover plate 42. The multiple bull's-eye bearings 41 are located within the anti-slip ring 44 to prevent the cover plate 42 from detaching from the bull's-eye bearings 41. A fine-tuning slider 43 is mounted on the lower end surface of the upper fixed plate 12. The bottom end of the fine-tuning slider 43 is hemispherical and abuts the upper end surface of the cover plate 42.

[0074] When the locking sleeve 341 is not tightly pressed against the locking shaft 342, the upper fixing plate 12 is stably placed on the lower fixing plate 11 by fine-tuning the slider 43, the cover plate 42 and the bull's eye bearing 41. At this time, the upper fixing plate 12 can be shaken horizontally to adjust its own position. At this time, the upper fixing plate 12 is in an unlocked state.

[0075] As the mounting platform 1 continues to move toward the power generating device, the resistance between the wall of the insertion hole of the power generating device and the insertion end of the cylindrical structure of the test equipment is transferred to the upper fixed plate 12, causing the position of the upper fixed plate 12 to move slightly. The fine-tuning slider 43 moves on the cover plate 42 together with the upper fixed plate 12, causing the cover plate 42 to move horizontally on the bull's eye bearing 41, while supporting the upper fixed plate 12 and reducing the resistance of the upper fixed plate 12 during movement, so that the insertion end of the cylindrical structure of the test equipment is completely inserted into the insertion hole of the power generating device.

[0076] In order to lower the center of gravity of the connection between the upper fixing plate 12 and the fine-tuning slider 43, as shown in FIG. Figure 2 and Figure 4 As shown, a sinking groove 431 is coaxially opened on the upper end surface of the fine-tuning slider 43, and a sinking hole 121 is coaxially opened on the upper fixing plate 12 opposite the sinking hole 121 and connected to the sinking groove 431, thereby making the connection between the upper fixing plate 12 and the lower fixing plate 11 more stable.

[0077] The assembly tooling for the test equipment barrel structure of the present embodiment is implemented as follows: During assembly, the cylinder 333 is first driven to cause the wedge-shaped slider 331 to slide toward the locking slide 32. The locking slide 32 rises until the first tapered surface 344 abuts the second tapered surface 345, locking the upper fixing plate 12. Next, the tray 6 carrying the test equipment barrel structure is placed on the upper fixing plate 12. The linear module 22 then drives the mounting platform 1 to slide toward the power generator, gradually inserting the insertion end of the test equipment barrel structure into the insertion port of the power generator.

[0078] When the force sensor 23 senses that the insertion end of the test equipment cylinder structure is not fully inserted into the insertion port of the power generating device (that is, the coaxiality between the insertion end of the test equipment cylinder structure and the insertion port of the generator is not high), the locking assembly 3 unlocks the position of the upper fixed plate 12. As the moving assembly 2 continues to drive the mounting platform 1 close to the power generating device, the resistance between the hole wall of the power generating device insertion hole and the insertion end of the test equipment cylinder structure is transferred to the upper fixed plate 12, causing the position of the upper fixed plate 12 to move slightly. The fine-tuning slider 43 moves on the cover plate 42 together with the upper fixed plate 12, causing the cover plate 42 to move horizontally on the bull's eye bearing 41, so that the insertion end of the test equipment cylinder structure can adjust its own position while being fully inserted into the insertion port of the generator, and finally completing the assembly of the test equipment cylinder structure, thereby improving the assembly efficiency of the test equipment cylinder structure and reducing the assembly workload.

[0079] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
