Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft windshield structure repair technology, specifically to a shape-preserving tooling for aircraft windshield structure repair. Background Technology
[0002] The aircraft cockpit structure consists of a fixed windshield and a movable canopy, serving as the pilot's direct window to the outside world. During base-level maintenance, the windshield needs to be disassembled and repaired. During disassembly and reassembly, the structural dimensions are highly susceptible to change. Because the windshield and canopy have a sealed fit, it is crucial to strictly control changes in the windshield's structural dimensions during repairs to meet technical specifications and achieve the desired functionality.
[0003] When using conformal tooling for windshield structures of different aircraft, the tooling used for controlling and adjusting the external dimensions of the windshield structure during repair is highly specific due to the differences in the external dimensions of the windshield structure. This results in conformal tooling having no universal application. As a result, in order to ensure the normal operation of aircraft windshield structure repair, it is necessary to configure a large number of conformal tooling on-site to achieve the functions of dimensional control, maintenance and adjustment during aircraft windshield structure repair.
[0004] However, different conformal tooling is suitable for different aircraft windshield structures, and cannot be interchanged when tasks are unevenly distributed. This restricts the scheduling of repair work, creating a vicious cycle. As a result, windshield structure repair work is inefficient, the utilization rate of different types of conformal tooling is low, and the precision of tooling manufacturing is low. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model proposes a conformal tooling for aircraft windshield structure repair. This tooling enables interchangeability between different aircraft windshield structure repair conformal tooling, satisfies the dimensional control and adjustment functions required for repairing different aircraft windshield structures, solves the problem of needing to manufacture conformal tooling specifically for different aircraft windshield structures, and avoids the waste and occupation of a large amount of conformal tooling resources, which would hinder the normal progress of repair work.
[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:
[0007] A type of aircraft windshield structure repair and conformal tooling, comprising:
[0008] The fixed base has an overall U-shaped structure and is used to fix the conformal tooling to the aircraft fuselage structure.
[0009] The fixed top mount has an overall U-shaped structure and is used to snap into and install the repair end required for the aircraft windshield. Manual tightening components are provided at both ends of its U-shape.
[0010] A fixed connection assembly is used to connect the fixed base and the fixed top seat. The connection length of the fixed connection assembly and the connection position with the fixed base are adjustable.
[0011] As a further improvement of this utility model, the fixed base has two sets of positioning holes and one set of moving holes at both ends of the U-shape.
[0012] As a further improvement of this utility model, the top of the fixed base is provided with a base connecting part, and the base connecting part is provided with four sets of connecting holes.
[0013] As a further improvement of this utility model, the fixed connection assembly includes two fixed threaded rods and a movable threaded rod connecting the two fixed threaded rods. Each of the two fixed threaded rods has a connecting end. The connecting end of one of the fixed threaded rods is connected to any one of the four sets of connecting holes by a quick-release pin, and the connecting end of the other fixed threaded rod is connected to the fixed top seat by a quick-release pin.
[0014] As a further improvement of this utility model, the movable threaded rod has a hollow structure and a rotating part is provided on its outside.
[0015] As a further improvement of this utility model, a top seat connecting part is provided on one side of the bottom of the fixed top seat, and four threaded holes are provided at both ends of the U-shape. The connecting end of another fixed threaded tie rod is connected to the top seat connecting part by a quick release pin.
[0016] As a further improvement of this utility model, the manual tightening assembly is provided in four sets, which are installed on the four threaded holes respectively. Each set of manual tightening assemblies includes a tightening handle installed on the threaded hole and a fixing block fixedly connected to the end of the tightening handle.
[0017] The beneficial effects of this utility model are:
[0018] This utility model provides a conformal tooling for aircraft windshield structure repair. Through the large-margin adjustment function of the fixed base and the movable threaded rod, it effectively solves the problem that conformal tooling for different aircraft windshield structures cannot be used interchangeably, avoids the repeated manufacturing of windshield structure conformal tooling, avoids redundancy in repair tooling, improves the utilization rate of aircraft windshield structure conformal tooling, and at the same time greatly saves repair costs and shortens the repair cycle.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] like Figure 1 As shown, a repair and maintenance fixture for an aircraft windshield structure mainly includes a fixed base 1, a fixed threaded pull rod 2, a movable threaded pull rod 3, a quick-release pin 4, a fixed top seat 5, and a manual tightening assembly 6. Two fixed threaded pull rods 2 are provided, and the two fixed threaded pull rods 2 are threadedly connected to the movable threaded pull rod 3. The two fixed threaded pull rods 2 and the movable threaded pull rod form a fixed connection assembly, which connects the fixed base 1 and the fixed top seat 5 through the quick-release pin 4. Four sets of the manual tightening assembly 6 are provided, correspondingly installed at both ends of the fixed top seat 5.
[0030] Furthermore, such as Figure 2As shown, the fixed base 1 has an overall U-shaped structure and is used to fix and connect the aircraft windshield structure. Two sets of positioning holes 11 and one set of movable holes 12 are provided at both ends of the U-shape of the fixed base 1. The positioning holes 11 are used to position and install the fixed base 1 onto the aircraft fuselage structure according to actual operational needs. The movable holes 12 are used to install the fixed base 1 onto the aircraft fuselage structure via the quick-release pins 4 after installation through the positioning holes, maintaining the fixed base 1 in a locked position on the aircraft fuselage structure. A base connecting part 13 is provided at the top of the fixed base 1, and four sets of connecting holes 14 are provided on the base connecting part 13. The connecting holes 14 are used to connect the fixed threaded tie rod 2. The multiple sets of connecting holes 14 allow for selection of appropriate positioning holes for installation according to the windshield structure adjustment requirements, thus enabling the installation position of the fixed threaded tie rod 2 to be selected according to the size control and adjustment requirements during use.
[0031] like Figure 3 As shown, the fixed threaded rod 2 is provided with a connecting end 21. The connecting end 21 on the lower fixed threaded rod 2 is connected to the connecting hole 14 on the top of the fixed base 1 through the quick-release pin 4. The connecting end 21 on the upper fixed threaded rod 2 is connected to the fixed top seat 5 through the quick-release pin 4.
[0032] like Figure 4 As shown, the movable threaded rod 3 has a hollow structure with internal threads, and its two ends are threadedly connected to two fixed threaded rods 2 respectively. The movable threaded rod 3 has a rotating part 31 on its outside. By rotating the movable threaded rod 3, the overall size of the tooling can be adjusted, thereby realizing the size control and adjustment technical requirements required for the repair of the aircraft windshield structure.
[0033] like Figure 6 As shown, the fixed top seat 5 has an overall U-shaped structure and is used to snap into and install the repair end required for the aircraft windshield. A top seat connecting part 51 is provided on one side of the bottom of the fixed top seat 5. The top seat connecting part 51 is connected to the connecting end 21 on the upper fixed threaded pull rod 2 via the quick-release pin 4. Four threaded holes 52 are provided at both ends of the U-shape of the fixed top seat 5, and four sets of manual tightening components 6 are correspondingly installed in the four threaded holes 52.
[0034] like Figure 7 As shown, the manual tightening assembly 6 includes a tightening handle 61 and a fixing block 62. The tightening handle 61 is threaded into the threaded hole 52, and the fixing block 62 is fixedly connected to the end of the tightening handle 61. By rotating the tightening handle 61, the fixing block 62 is fitted and fixed to the aircraft windshield structure, preventing misalignment or slippage from the fixed top seat 5 during size control and adjustment.
[0035] Working principle and usage process of this utility model:
[0036] First, install the four sets of manual tightening components 6 and the fixed top seat 5 on the ground by screwing them in. After installation, install the fixed base 1 and the lower fixed threaded tie rod 2, and the fixed top seat 5 and the upper fixed threaded tie rod 2 by quick-release pins 4. Then, tighten the two fixed threaded tie rods 2 by the movable threaded tie rod 3. Next, according to the actual repair needs, fix and adjust the fixed base 1 by selecting the installation position of the positioning hole 11 and the movable hole 12 on the fixed base 1. According to the required size requirements for the repair of the aircraft windshield structure, rotate the movable threaded tie rod 3 by rotating the rotating part 31 to achieve the control and adjustment function of the repair size of different shaped windshield structures. Finally, fix the aircraft windshield structure to be repaired on the fixed top seat 5 and clamp it with the manual tightening components 6 for repair.
