[0033] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0034] refer to Figure 1-4 A specific embodiment of the present invention provides a device for automatically releasing a standard block in a closed space of an aircraft guide block station, which is installed in a closed cavity of a closed housing 1 and includes:

[0035] A limit slider 3, the limit slider 3 is rotatably connected to the inner wall of the closed cavity;

[0036] The main body positioning body 4 is limited on the limiting slider 3;

[0037] A release unit, the release unit is slidably connected to the main positioning body 4, the standard block 8 is clamped on the release unit and is arranged corresponding to the bottom plane;

[0038] The servo electric cylinder 5 is fixedly connected to the main positioning body 4, the release unit is installed at the telescopic end of the servo electric cylinder 5, and the standard block 8 pushes the release unit through the servo electric cylinder 5 and is bonded to the bottom plane.

[0039] In the existing operation method, during the positioning process of the guide part mounting holes, the mounting hole positions of the aircraft guide parts cannot be accurately determined at one time, and highly skilled operators are required to achieve relatively accurate hole positions through multiple processing and correction using an approximation method. Among them, the operators have high professional skill requirements, the operation is time-consuming, and multiple repeated corrections are required to process qualified products. In the present application, by bonding the standard block 8 to the bottom plane and taking the standard block 8 as an auxiliary reference, the accurate positioning of the installation hole of the quick time guide according to the auxiliary reference is improved, thereby improving the positioning accuracy and the production efficiency; wherein, the main function of the release unit is to install the standard block 8, and the servo electric cylinder 5 drives the release unit to gradually approach and fit on the bottom plane after being extended. Since the main positioning body 4 is rotatably connected to the inner wall of the closed cavity through the limit slider 3, when the release unit is not fully fitted on the bottom plane, under the thrust of the servo electric cylinder 5, the main positioning body 4 rotates a certain angle until the release unit is fully and completely fitted on the bottom plane, so as to achieve the purpose of automatic leveling and avoid installation errors, and then continue to extend the servo electric cylinder 5 to push the standard block 8 in the release unit, so as to fit the bonding surface of the standard block 8 to the bottom plane, complete the bonding of the standard block 8 to the bottom plane, and ensure the stable connection relationship between the standard block 8 and the bottom plane, and then the servo electric cylinder 5 retracts with the release unit, and the release unit is separated from the standard block 8. On the whole, the present application can assist in locating the installation holes of the aircraft guide parts by accurately and quickly installing the standard block 8, thereby improving work efficiency.

[0040] The size of the closed cavity of the closed shell 1 is 100*40*50 mm, and the bottom plane is located outside the closed cavity of the closed shell 1 .

[0041] To further optimize the solution, the release unit includes:

[0042] The correction slider 7 is slidably connected to the main positioning body 4, and the telescopic end of the servo electric cylinder 5 is slidably connected in the correction slider 7 and is correspondingly arranged with the standard block 8 clamped on the correction slider 7;

[0043] The spring 10 is sleeved on the telescopic end of the servo electric cylinder 5 , and the spring 10 abuts between the inner wall of the correction slide block 7 close to the standard block 8 and the telescopic end of the servo electric cylinder 5 .

[0044] Under the elastic force of the spring 10, the correction slider 7 is limited on the telescopic end of the servo electric cylinder 5; after the servo electric cylinder 5 starts to extend, it drives the correction slider 7 to move toward the bottom plane. When the correction slider 7 is in point contact or line contact with the bottom plane, the main positioning body 4 will be pushed to rotate a certain angle during the continuous extension of the servo electric cylinder 5, so that the correction slider 7 is in full surface contact with the bottom plane; at this time, the servo electric cylinder 5 continues to extend, the spring 10 is compressed, the correction slider 7 remains stationary, and the servo electric cylinder 5 pushes the standard block 8 so that the bonding surface of the standard block 8 abuts and bonds to the bottom plane.

[0045] To further optimize the solution, the release unit also includes:

[0046] The fixing plate 13 is fixedly connected to the side of the correction slider 7 away from the standard block 8 and is located between the servo electric cylinder 5 and the correction slider 7 . The telescopic end of the servo electric cylinder 5 abuts against the fixing plate 13 through the spring 10 .

[0047] The main function of the fixing plate 13 is to limit the telescopic end of the servo electric cylinder 5 within the correction slider 7 , and then the telescopic end of the servo electric cylinder 5 is abutted against the fixing plate 13 through the spring 10 .

[0048] According to a further optimized solution, the telescopic end of the servo electric cylinder 5 is fixedly connected with a top block 9 , and the top block 9 abuts against the fixed plate 13 through a spring 10 .

[0049] To further optimize the solution, the release unit also includes:

[0050] The placement groove 12 is provided on the side of the correction slider 7 away from the servo electric cylinder 5, and the standard block 8 is clamped in the placement groove 12; wherein, the standard block 8 is adapted in the placement groove 12, and a plurality of rubber blocks are arranged on the inner peripheral side wall of the placement groove 12. After the standard block 8 is placed in the placement groove 12, a force is generated between the standard block 8 and the plurality of rubber blocks, that is, a force generated by extrusion, and the standard block 8 cannot escape from the extrusion of the plurality of rubber blocks due to its own gravity; when the standard block 8 is bonded to the bottom plane, as the correction slider 7 is away from the bottom plane, the force generated by extrusion is less than the bonding force, and the standard block 8 remains bonded to the bottom plane. The rubber block can also be replaced by a plastic block.

[0051] The through hole 11 is opened on the inner wall of the placement groove 12 , and the top block 9 passes through the through hole 11 and is arranged corresponding to the standard block 8 .

[0052] Under the action of the spring 10, the top block 9 is abutted against the fixed plate 13; when the correction slider 7 fully contacts the bottom plane, the servo electric cylinder 5 continues to extend, and the top block 9 overcomes the elastic force of the spring 10 and passes through the through hole 11, pushing the standard block 8 clamped in the placement groove 12 until it is bonded to the bottom plane; when the servo electric cylinder 5 is shortened, under the action of the elastic force of the spring 10, the correction slider 7 continues to abut against the bottom plane, and when the top block 9 contacts the fixed plate 13, the correction slider 7 and the top block 9 begin to move synchronously and away from the bottom plane, and the standard block 8 bonded to the bottom plane gradually detaches from the placement groove 12 until the servo electric cylinder 5 is fully retracted and the standard block 8 is completely detached from the placement groove 12.

[0053] To further optimize the solution, the release unit also includes:

[0054] The cavity is opened in the correction slider 7 and communicated with the through hole 11. The top block 9 is slidably connected in the cavity. The spring 10 is located in the cavity and sleeved on the top block 9.

[0055] Further optimization plans also include:

[0056] The rotating shaft 2 passes through the side wall of the closed shell 1 and is rotatably connected to the closed shell 1 . The limiting slider 3 is fixedly connected to the rotating shaft 2 .

[0057] The limiting slider 3 is rotatably connected to the inner wall of the closed shell 1 through the rotating shaft 2.

[0058] Further optimization plans also include:

[0059] The square groove 6 is provided on the main positioning body 4 , the limit slider 3 is radially slidably connected in the square groove 6 along the rotating shaft 2 , and the screw penetrates the square groove 6 and abuts against the side wall of the limit slider 3 .

[0060] The limiting slider 3 slides into the square groove 6 and is then fastened in the square groove 6 by screws, so that the main positioning body 4 and the limiting slider 3 are detachably connected, thereby improving assembly efficiency.

[0061] Further optimization plans also include:

[0062] A control circuit board, which is installed in the main positioning body 4 and is electrically connected to the servo electric cylinder 5;

[0063] Power module: The power module is installed on the control circuit board.

[0064] The main board PCB in the control circuit board adopts a 4-layer board design, and the STM32F103C8T6 chip is selected as the main control. The onboard charging management chip, discharge LDO linear regulator, three-color light, passive buzzer, DCDC boost module, EMC protection, fuse, Type-C interface and magnetic charging interface are all integrated into the PCB board with an outer size of 44*35*4mm, and its front and back structural layout. The power module is powered by a customized lithium polymer battery, and the standard quick-change design is adopted in the structural design, which can facilitate the battery charging management.
