Description

Technical Field

[0001] This utility model relates to the field of inflatable valve repair, specifically an inflatable valve repair device. Background Technology

[0002] The function of the inflation valve is to inflate the aircraft's accumulator. When filling the accumulator with nitrogen, a special tool is used to push the valve's rod assembly to a certain depth, establishing communication between the external air source and the accumulator's interior, and then inflation begins. After inflation is complete, the connection between the special tool and the rod assembly is disconnected. The rod assembly resets under the force of the spring and the internal air source pressure, and the cone fits against the housing, ensuring the inflation valve's seal. The inflation valve's structure mainly consists of the rod assembly, bushing, housing, spring, and other components. During repair, the product needs to be disassembled for inspection. During disassembly, the pins on the rod assembly need to be removed, and then reassembled. Before reassembly, positioning holes need to be drilled for the new bushing and rod assembly. The specific operation involves fixing the rod assembly and repositioning the holes at the pin locations.

[0003] To address the issue of positioning and drilling after replacing inflatable valve bushings and rod assemblies during repair, an inflatable valve repair device was designed, featuring the following technical characteristics: First, the repair device includes a rod assembly fixing base to secure the rod assembly during the disassembly and assembly of the inflatable valve; second, the repair device includes pin holes to eject the pins during rod assembly disassembly; third, the repair device includes a drilling positioning bracket, allowing for re-drilling of the bushing and rod assembly during repair; fourth, the repair device is simple to use and can be directly operated on-site, accurately positioning the drilled holes for replacing inflatable valve bushings and rod assemblies, improving work efficiency and enhancing the reliability of repair quality. Utility Model Content

[0004] To solve the above problems, this utility model proposes an inflatable valve repair device.

[0005] A repair device for an inflatable valve includes a fixed base, a rod assembly base for embedding an inflatable valve rod assembly into the fixed base, and a positioning bracket.

[0006] The fixed base, rod assembly base, and positioning bracket are all fixed by tightening screws;

[0007] The rod assembly base is provided with a bushing for fixing the inflatable valve and clamping bolts and clamping washers for clamping the rod assembly.

[0008] The beneficial effects of this utility model are:

[0009] This invention features a rod assembly base for easy fixation of the rod assembly during the disassembly and assembly of the inflatable valve; a positioning hole seat to push out the pin during rod assembly disassembly; and a drilling positioning bracket for re-drilling the bushing and rod assembly. This invention is simple to use and can be directly operated on-site, accurately positioning the drilling for replacing the bushing and rod assembly of the inflatable valve, improving work efficiency and enhancing quality stability.

[0015] 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.

[0016] like Figure 1 and Figure 2 As shown, an inflatable valve repair device includes a fixed base 1, a rod assembly base 2 for embedding the inflatable valve rod assembly into the fixed base 1, and a positioning bracket 5.

[0017] like Figure 2 As shown, the fixed base 1, the rod assembly base 2 and the positioning bracket 5 are all tightened and fixed by the fixing screws 7, and fixed by the clamping bolts 3 and the clamping washers 4. When disassembling, the pin 13 is rotated to the pin hole position of the rod assembly base 2, the positioning hole seat 6 on the positioning bracket 5 is removed, and the pin 13 is pushed out by the center punch through the positioning bracket 5.

[0018] like Figure 2 As shown, the rod assembly base 2 is provided with a bushing for fixing the inflatable valve, a clamping bolt 3 for the rod assembly, and a clamping washer 4. The fixing base 1, the rod assembly base 2, and the positioning bracket 5 of the inflatable valve repair device are tightened and fixed by fixing screws 7, and the bushing 12 and the rod 14 of the inflatable valve are embedded into the rod assembly base 2.

[0019] Furthermore, such as Figure 1and Figure 2 As shown, the fixed base 1 and the rod assembly base 2 are in a concave-convex fit. The rod assembly base 2 is provided to facilitate the fixing of the rod assembly during the disassembly and assembly of the inflatable valve. A positioning hole seat 6 is provided to push out the pin when disassembling the rod assembly. A drilling positioning bracket 5 is provided to re-drill holes in the bushing 12 and the rod 14. This utility model is simple to use and can be directly operated on site. It can accurately perform drilling positioning for replacing the bushing 12 and the rod 14 of the inflatable valve, improve work efficiency, and enhance quality stability.

[0020] like Figure 1 and Figure 2 As shown, the positioning bracket 5 is provided with a positioning hole seat 6 for drilling. When repositioning and drilling is performed after the bushing 12 and rod assembly 14 are replaced, the parts are fixed and an electric drilling tool is used to drill vertically downward through the hole on the positioning hole seat 6 on the positioning bracket 5 until the bushing 12 and rod 14 are penetrated, so as to achieve accurate positioning drilling during the repair process of the inflatable valve rod assembly.

[0021] As a further optimization of this utility model, the positioning bracket 5 is configured as a T-shape.

[0022] As a further optimization of this utility model, the positioning bracket 5 is provided with an extension plate.

[0023] As a further optimization of this utility model, the positioning hole seat 6 is set on the extension plate. The air valve repair device is used to drill holes for repositioning the bushing 12 and rod 14 after they are replaced during the repair process. This can accurately perform drilling and positioning of the air valve bushing 12 and rod 14 after replacement, improve work efficiency, and enhance the reliability of repair quality.

[0024] The specific process steps of this utility model are as follows:

[0025] 1. Fixing rod assembly: The inflatable valve rod assembly is embedded into the fixing base 1 of the repair device and fixed by the clamping bolts 3 and the clamping pads 4;

[0026] 2. Disassemble pin 14: Rotate pin 14 of the rod assembly to the pin hole position of the support, remove the positioning hole seat 6 on the positioning bracket 5, and use a punch to push out the pin through the positioning bracket 5.

[0027] 3. Positioning Drilling: After fixing the new bushing and rod assembly to the base 1, use an electric drilling tool to drill vertically downwards through the hole in the positioning hole seat 6 on the pin hole positioning bracket 5 until the bushing 12 and rod 14 are penetrated.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
