Description

Technical Field

[0001] The utility model relates to the technical field of maintenance training, in particular to a connection structure of maintenance training components. Background Art

[0002] Many components on the aircraft fuel system need to be disassembled and installed during the actual maintenance process. In order to train students' ability to disassemble and assemble components, special disassembly and assembly training equipment is needed for students to conduct practical training.

[0003] However, during the component disassembly and assembly training process, since the trainees' own abilities are generally poor, damage to the disassembly and assembly parts will frequently occur, thereby causing damage to the equipment and increased costs. Utility Model Content

[0004] Since existing training equipment does not consider the problem of repairing and replacing easily damaged parts, if a part is damaged due to improper operation, the entire part needs to be replaced, resulting in excessively high training costs. In order to solve this problem, the utility model provides a connection structure for repairing training parts, which can increase the convenience of equipment maintenance and greatly reduce maintenance costs.

[0005] The utility model of the present application provides a connection structure of components for maintenance training, including:

[0006] The body structure is provided with a first threaded hole;

[0007] A threaded sleeve, threadedly connected to the first threaded hole, the threaded sleeve is provided with an axial threaded through hole extending along its own axial direction;

[0008] A screw, threadedly connected to the axial threaded through hole;

[0009] The nut has a second threaded hole, and the portion of the thread sleeve passing through the first threaded hole is threadedly connected to the second threaded hole;

[0010] A position sensor is installed on the nut and is used to detect whether the screw is installed in place.

[0011] In one embodiment, the nut is provided with a radial mounting through hole extending in its radial direction, and the position sensor is passed through the radial mounting through hole.

[0012] In one embodiment, the radial mounting through hole is a third threaded hole, and the position sensor is threadedly connected to the third threaded hole.

[0013] In one embodiment, the axis of the radial mounting through hole and the axis of the nut are perpendicular to each other and intersect.

[0014] In one embodiment, the position sensor is a distance sensor or an infrared sensor.

[0015] In one embodiment, the second threaded hole is a through hole structure.

[0016] In one embodiment, the axis of the axial threaded through hole is colinear with the axis of the wire sleeve.

[0017] In one embodiment, the outer wall of the thread sleeve is a full-thread structure.

[0018] In one embodiment, a nut is provided on the end of the screw rod away from the thread sleeve.

[0019] In one embodiment, the nut is provided with a tool connection port.

[0020] The advantages or beneficial effects of the above technical solution include at least:

[0021] 1. Since the wire sleeve and the screw can be disassembled from each other, when the two are frequently assembled and disassembled, if one of them is damaged, the other can continue to be used for training, and the easily damaged wire sleeve can be replaced in time, thereby ensuring the continued integrity of the overall components, reducing training costs, and shortening maintenance time and costs.

[0022] 2. Use the position sensor to detect whether the thread sleeve and the screw are installed in a misaligned position, so as to detect whether the trainees strike the screw accurately and in place.

[0023] 3. Importantly, since the high-frequency friction location is between the wire sleeve and the screw, rather than between the wire sleeve and the body structure, the body structure is not easily damaged, that is, there is no need to replace the body structure, which greatly reduces the loss cost; compared with the traditional high-frequency assembly of the body structure and the wire sleeve, which leads to frequent damage and replacement of the body structure, the connection structure of the maintenance training components of the present application saves more training costs.

[0024] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present application will be readily apparent by reference to the accompanying drawings and the following detailed description.

[0029] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0030] See also Figure 1 , shows a connection structure of a maintenance training component in a preferred embodiment of the utility model, including: a body structure 1, a thread sleeve 2, a screw rod 3, a nut 4 and a position sensor 5.

[0031] The body structure 1 is provided with a first threaded hole 11 . It can be understood that the first threaded hole 11 is an internal threaded hole structure.

[0032] The thread sleeve 2 is threadedly connected with the first threaded hole 11. It can be understood that the first threaded hole 11 is an internal threaded hole, that is, the external thread of the thread sleeve 2 matches the first threaded hole 11. The thread sleeve 2 is provided with an axial threaded through hole 21 extending along its own axial direction.

[0033] The screw rod 3 is threadedly connected to the axial threaded through hole 21, that is, the screw rod 3 and the wire sleeve 2 are detachably connected. When one of them is damaged, the other can continue to be used, thereby reducing the loss cost, that is, reducing the training cost of the trainees.

[0034] The nut 4 has a second threaded hole 41, and it can be understood that the second threaded hole 41 is an internal thread structure. The portion of the thread sleeve 2 passing through the first threaded hole 11 is threadedly connected to the second threaded hole 41, so that the nut 4 is tightly connected to the thread sleeve 2, and thus the nut 4 can be used as a mounting carrier to support the position sensor 5.

[0035] The position sensor 5 is installed on the nut 4 and is used to detect whether the screw rod 3 is installed in place, so as to detect whether the trainee strikes the screw rod 3 accurately.

[0036] When in use, after the thread sleeve 2 is driven into the body structure 1, the nut 4 is connected to the thread sleeve 2. In this way, the thread sleeve 2 is used as an intermediate piece to fasten the body structure 1 and the nut 4 together. After confirming that the thread sleeve 2 is accurate, the trainee starts training and drives the screw 3 into the thread sleeve 2, and then uses the position sensor 5 to detect whether the screw 3 is installed in place. Among them, the same trainee can drive in and out the screw 3 on the same installed thread sleeve 2 multiple times, and the thread sleeve 2 does not need to be replaced until the thread sleeve 2 is distorted or damaged, etc.; that is, after the thread sleeve 2 is installed, the trainee only needs to complete multiple installation and removal training of the screw 3.

[0037] Obviously, based on the fact that the silk sleeve 2 and the screw rod 3 can be disassembled from each other, when the two are frequently assembled and disassembled from each other, if one of them is damaged, the other can continue to be used for training, and the easily damaged silk sleeve 2 can be conveniently replaced in time, thereby ensuring the continuous integrity of the overall components, reducing the training cost, shortening the maintenance time and maintenance cost. In addition, the position sensor 5 is used to detect whether the screw rod 3 is installed in place to detect whether the trainee attacks the screw rod 3 accurately. Importantly, based on the fact that the high-frequency friction part is between the silk sleeve 2 and the screw rod 3, rather than between the silk sleeve 2 and the body structure 1, the body structure 1 is not easily damaged, that is, there is no need to replace the body structure 1, which greatly reduces the loss cost; compared with the traditional high-frequency assembly of the body structure 1 and the silk sleeve 2, which leads to frequent damage and replacement of the body structure 1, the connection structure of a maintenance training component of the present application saves more training costs.

[0038] In one embodiment, in order to conveniently and reliably fix the position sensor 5, the nut 4 is provided with a radial mounting through hole 42 extending along its radial direction, and the position sensor 5 is passed through the radial mounting through hole 42. It can be understood that, as an alternative arrangement, the position sensor 5 can be mounted on the nut 4 by bonding, magnetic connection, etc.

[0039] In one embodiment, in order to further improve the installation stability of the position sensor 5, the radial installation through hole 42 is a third threaded hole, and the position sensor 5 is threadedly connected to the third threaded hole. It can be understood that as an alternative arrangement, the position sensor 5 can be fitted in the radial installation through hole 42 by friction force interference.

[0040] In one embodiment, in order to prevent the position sensor 5 from being crushed by the screw rod 3 and to make the detection of the position sensor 5 more accurate, the axis of the radial mounting through hole 42 and the axis of the nut 4 are perpendicular to and intersect each other.

[0041] The position sensor 5 may be a micro switch, a distance sensor or an infrared sensor, etc.

[0042] In one embodiment, in order to facilitate the instructor to observe whether the thread sleeve 2 is accurately connected to the body structure 1, preferably, the second threaded hole 41 is a through hole structure.

[0043] In one embodiment, the axis of the axial threaded through hole 21 is colinear with the axis of the thread sleeve 2. This arrangement means that the axial threaded through hole 21 is arranged at the center line of the thread sleeve 2, so that the position sensor 5 can detect the screw 3 more conveniently.

[0044] In one embodiment, in order to prevent the silk sleeve 2 from being exposed outside the body structure 1 and being bumped, preferably, the outer wall of the silk sleeve 2 is a full-thread structure.

[0045] In one embodiment, in order to facilitate the control of the screw rod 3 , a nut 31 is provided on one end of the screw rod 3 away from the thread sleeve 2 .

[0046] In one embodiment, in order to facilitate the screwing of the nut 31, the nut 31 is provided with a tool connection port, and the tool connection port can be a hexagonal hole, a cross hole, a slotted hole, etc.
