Detailed Implementation
[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0039] refer to Figure 1-3 A specific embodiment of this utility model provides an aviation pipeline measurement fixture, comprising:
[0040] Fixture 1, with a scale on it;
[0041] The first vertebral body 2 is vertically fixed to the fixed base 1, and the first end of the tube to be measured is adapted to the conical surface of the first vertebral body 2.
[0042] The second vertebral body 16 is set perpendicular to the first vertebral body 2. The large-diameter end of the second vertebral body 16 is slidably connected to the fixed seat 1 along the radial direction of the first vertebral body 2. The second end of the tube to be measured is adapted to the conical surface of the second vertebral body 16.
[0043] The right-angle reference adjustment unit is mounted on the fixed base 1 and is fitted to the side wall of the tube to be measured.
[0044] The measurement of general aviation pipelines mainly relies on various measuring tools. However, for more complex pipelines with 90-degree bends, ordinary measuring tools (such as calipers, reels, and ordinary optical measuring instruments) are difficult to meet the measurement of key parameters, and are inconvenient to operate, have low accuracy, and have measurement blind spots. In this application, the second cone 16 is set perpendicular to the first cone 2, mainly used for measuring pipes with 90-degree bends. The conical surfaces on the second cone 16 and the first cone 2 correspond to the two ends of the pipe to be measured, so that pipes of different sizes have a more stable measurement position during the measurement process, improving the measurement accuracy. By measuring the position of the second cone 16 on the fixed base 1, the distance between the axis of the first cone 2 and the second cone 16 can be quickly measured, that is, the axial dimension of the pipe to be measured. The right-angle reference surface of the right-angle reference adjustment unit is set to fit against the side wall of the pipe to be measured. After the end of the pipe to be measured is engaged with the conical surface, the right-angle reference surface of the right-angle reference adjustment unit is fully fitted against the side wall of the pipe to be measured, further ensuring the measurement accuracy of the pipe to be measured. This application can accommodate pipelines with bending angles and effectively improve measurement accuracy, obtaining complete measurement data.
[0045] Further optimization of the scheme, the tubes to be measured include:
[0046] Hose 4, the sidewall of hose 4 is fitted to the right angle reference surface of the right angle reference adjustment unit;
[0047] The first pipe connector 3 is a right-angle elbow connector. The first end of the first pipe connector 3 is adapted to the conical surface of the first vertebra 2 along the axis. The second end of the first pipe connector 3 is fixedly engaged with the first end of the hose 4.
[0048] The second pipe connector 7 has its first end axially adapted to the conical surface of the second vertebral body 16, and its second end fixedly engaged with the second end of the hose 4.
[0049] The flexible hose 4 is fully fitted with the right-angle reference surface of the right-angle reference adjustment unit, which can constrain the flexible hose 4 radially and make the axial dimension measurement more accurate. The pipe openings of the first pipe joint 3 and the second pipe joint 7 are respectively provided with conical surfaces, which are adapted to the conical surfaces of the first cone 2 and the second cone 16, thereby stabilizing the measurement reference of the pipe to be measured and improving the measurement accuracy and stability.
[0050] Further optimization of the scheme includes the following right-angle reference adjustment unit:
[0051] The first reference plate 5 and the second reference plate 6 are set perpendicularly to each other.
[0052] Connecting plate 10 is fixedly connected to the first reference plate 5 and the second reference plate 6 at the connection point;
[0053] The limiting part is connected between the connecting plate 10 and the fixed base 1. By adjusting the limiting part, the first reference plate 5 and the second reference plate 6 on the connecting plate 10 are moved closer to or away from the hose 4.
[0054] The first reference plate 5 and the connecting plate 10 can be set on the same plane. By manually operating the limiting part, the connecting plate 10 can be moved, thereby making the first reference plate 5 and the second reference plate 6 closer to or further away from the hose 4.
[0055] The scheme is further optimized so that the first reference plate 5 and the second reference plate 6 are set at the right angle near the first pipe joint 3 at the same end.
[0056] The radial deformation of the hose 4 near the first pipe joint 3 is small and can be ignored. When the first reference plate 5 and the second reference plate 6 respectively contact the hose 4 near the first pipe joint 3, this position can be used as a reference. Then, the deformed part at the middle end of the hose 4 is made to fit against the first reference plate 5 and the second reference plate 6. Finally, the hose 4 is fully fitted with the first reference plate 5 and the second reference plate 6, so that the hose 4 can be in a precise measurement state, effectively improving the measurement accuracy.
[0057] The design has been further optimized, and the limiting part includes:
[0058] The second sliding column 13 and the connecting plate 10 are axially sleeved on the two sets of second sliding columns 13. The second reference plate 6 and the connecting plate 10 are close to or away from the hose 4 along the sliding direction of the connecting plate 10.
[0059] The second limiting screw 14, two sets of the second limiting screw 14 are screwed into the connecting plate 10, and are respectively set to correspond to the second sliding column 13;
[0060] An adjusting component is installed on a fixed base 1, and a second sliding column 13 is installed on the adjusting component. The first reference plate 5, the second sliding column 13, and the connecting plate 10 move towards or away from the hose 4 through the adjusting component.
[0061] Manually move the connecting plate 10 to bring the second reference plate 6 closer to the hose 4. At this time, the second sliding column 13 slides and engages with the connecting plate 10. When the second reference plate 6 is in contact with the hose 4, tighten the second limit screw 14 and the second sliding column 13 is positioned on the connecting plate 10. Then manually adjust the adjusting component so that the connecting plate 10 drives the first reference plate 5 to be in contact with the hose 4 and completes the positioning.
[0062] Further optimization of the scheme, adjusting components includes:
[0063] The first sliding column 12, two sets of first sliding columns 12 are inserted parallel to each other into the fixed base 1, the first reference plate 5, the second sliding column 13 and the connecting plate 10 move closer to or further away from the hose 4 along the sliding direction of the first sliding column 12;
[0064] The first limiting screw 11, two sets of first limiting screws 11 are screwed into the fixing seat 1 and are set in correspondence with the first sliding column 12.
[0065] Specifically, when the second reference plate 6 is in contact with the hose 4, the connecting plate 10 is manually moved, which causes the first reference plate 5 to be in contact with the hose 4. Then, the first limit screw 11 is tightened, and the first sliding column 12 is positioned on the fixed seat 1, thereby completing the positioning of the hose 4.
[0066] The design has been further optimized, and the limiting part also includes:
[0067] Two sets of fixed sleeves 15 are fixedly connected to the side wall of the connecting plate 10. The second sliding column 13 is inserted into the end of the fixed sleeve 15 away from the second reference plate 6. Two sets of second limiting screws 14 are screwed into the two sets of fixed sleeves 15 respectively, and are respectively set to correspond to the two sets of second sliding columns 13.
[0068] The second sliding column 13 slides with the connecting plate 10 through the fixing sleeve 15. The two sets of second limiting screws 14 are screwed into the two sets of fixing sleeves 15 respectively to position the two sets of second sliding columns 13.
[0069] Further optimizations to the plan include:
[0070] The fixing column 8 is fixedly connected to the end of the second vertebral body 16 away from the cone surface;
[0071] Sliding sleeve 9 is fitted onto fixed seat 1 in a direction that is close to or away from the first vertebra 2.
[0072] After the first reference plate 5 and the second reference plate 6 are fully in contact with the side of the tube to be measured, that is, after the two sets of second limit screws 14 and the two sets of first limit screws 11 are tightened in sequence, the position of the sliding sleeve 9 is adjusted according to the size of the tube to be measured so that the conical surface of the second cone 16 and the second pipe connector 7 fully matches the conical surface of the tube to be measured, and then the size of the tube to be measured is measured.
