Description

Technical Field

[0001] This utility model relates to the field of fairing bonding tooling technology, and in particular to a fairing bonding tooling. Background Technology

[0002] Currently, the repaired fairing glass of the new integrated component needs to be reattached to the fairing housing.

[0003] In the early model, when the integrated fairing was repaired and bonded to the head cover shell, mechanical slots on the shell were used for positioning. However, due to the large gap between the metal parts and the glass, high positioning accuracy could not be guaranteed. The new integrated fairing requires the deviation between the center position of the fairing glass and the center position of the spherical shell to be no more than 0.15mm. It has been verified that the original bonding method cannot guarantee this accuracy requirement.

[0004] To address these issues, we propose a fairing bonding fixture that controls the concentricity of the fairing glass and the housing during bonding. During the project, due to increased product demand, we designed and manufactured an adapter fixture for bonding fairing glass of new optomechanical components based on the existing platform, which improved the compatibility of this fixture. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a fairing bonding fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fairing bonding fixture includes: a manual turntable, a centering shaft fixedly mounted on the top of the manual turntable, a centering fixture base rotatably mounted on the top of the centering shaft, and a positioning detection mechanism mounted on the centering fixture base and the manual turntable;

[0008] The positioning and detection mechanism includes three sets of equidistantly distributed horizontal top seats installed on the outer side of the bottom of the centering fixture base, a vertical top seat installed on the top of the centering fixture base, screw holes opened on the three sets of horizontal and vertical top seats, a top rod threaded into each set of screw holes, a rubber sleeve fixedly installed at the other end of each set of top rods, a mounting bracket fixedly installed on the side wall of the manual turntable, and a dial indicator fixedly installed on the top of the mounting bracket. The vertical top seats correspond to the centering shaft.

[0009] Preferably, a fairing is installed inside the centering fixture base, and the sidewalls of the fairing correspond to the four sets of top rods.

[0010] Preferably, a fairing mounting plate is installed on the side wall of the centering fixture base. The fairing mounting plate is threadedly connected to the side wall of the centering fixture base by fixing bolts, which can fix one side of the fairing.

[0011] Preferably, a positioning ring is fixedly installed on the top of the centering fixture base, and the side wall of the positioning ring corresponds to the side wall of the fairing, which can position the fairing.

[0012] Preferably, a vertical fixing seat is fixedly installed on one side of the bottom of the vertical top seat, and a horizontal fixing seat is fixedly installed on one side of each of the three sets of horizontal top seats, so that the vertical top seat and the horizontal top seat can be adjusted.

[0013] Preferably, each of the three sets of horizontal and vertical fixed seats has an adjustment groove in the middle, and each of the four sets of adjustment grooves has a clamping bolt slidably installed in it. Each of the four sets of clamping bolts is threaded to the side wall of the centering fixture base, which can fix the three sets of horizontal and vertical fixed seats.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a dial indicator to check the outer circle of the mandrel, allowing adjustment of the fairing mandrel position and ensuring coaxiality between the turntable shaft and the fairing spherical mandrel. Simultaneously, four sets of push rods within the screwing and positioning detection mechanism can push three sets of horizontal push rods to fit against the fairing sidewalls and the vertical push rods to fit against the top of the fairing, ensuring the fairing is firmly and stably positioned on the top of the centering fixture base. This device not only achieves glass position adjustment and centering but also stabilizes the glass position during bonding, preventing concentricity errors caused by epoxy adhesive curing shrinkage. Actual measurements show that the bonded fairing glass and shell are concentric, avoiding the scratches previously caused by the metal shell's retaining grooves on the fairing glass.

[0016] The three sets of horizontal and vertical fixed seats each have an adjustment groove in the middle, and clamping bolts are slidably installed in all four adjustment grooves. When the operator needs to adjust the position of the vertical top seat and also adjust the horizontal height of the three sets of horizontal top seats, the clamping bolts in the adjustment grooves can be tightened to adjust the vertical and horizontal fixed seats along the direction of the adjustment grooves. This not only fixes the height of the fairing glass from the top of the fixture and ensures the vertical spherical center deviation of the fairing glass, but also uses a dial indicator to detect the spherical roundness of the fairing glass. By finely adjusting the front and rear distance of the fairing mounting plate, the fairing glass can be made to ensure the horizontal spherical center deviation of the fairing glass when the turntable rotates.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 A fairing bonding fixture includes: a manual turntable 1, a centering shaft 14 fixedly mounted on the top of the manual turntable 1, a centering fixture base 11 rotatably mounted on the top of the centering shaft 14, and a positioning detection mechanism mounted on the centering fixture base 11 and the manual turntable 1.

[0023] The positioning and testing mechanism includes three sets of equidistantly distributed horizontal top seats 2 installed on the outer side of the bottom of the centering fixture base 11; a vertical top seat 21 installed on the top of the centering fixture base 11; screw holes 22 opened on each of the three sets of horizontal top seats 2 and vertical top seats 21; a push rod 23 threaded into each set of screw holes 22; a rubber sleeve 24 fixedly installed on the other end of each set of push rods 23; a mounting bracket 25 fixedly installed on the side wall of the manual turntable 1; and a dial indicator 26 fixedly installed on the top of the mounting bracket 25. The vertical top seat 21 corresponds to the centering shaft 14. A fairing is installed inside the centering fixture base 11, and the side wall of the fairing corresponds to the four sets of push rods 23. The centering shaft is tested by the dial indicator 26. The outer circle of the shaft can adjust the position of the fairing mandrel and ensure the coaxiality of the turntable shaft and the fairing spherical mandrel. At the same time, the four sets of push rods 23 in the screwing and positioning detection mechanism can push the push rods 23 inside the three sets of horizontal top seats 2 to fit against the side wall of the fairing, and also push the push rods 23 inside the vertical top seat 21 to fit against the top of the fairing, ensuring that the fairing can be firmly and stably positioned on the top of the centering fixture base 11. This device not only realizes the centering and adjustment of the glass position, but also stabilizes the glass position during the bonding process and prevents concentricity errors caused by the curing shrinkage of epoxy glue. Actual tests show that it can ensure the concentricity of the bonded fairing glass and the shell, and also avoids the problem of scratches caused by the original fairing glass relying on the metal shell groove.

[0024] Furthermore, a vertical fixing seat 3 is fixedly installed on one side of the bottom of the vertical top seat 21, and a horizontal fixing seat 31 is fixedly installed on one side of each of the three sets of horizontal top seats 2. This allows for adjustment of the vertical top seat 21 and the horizontal top seats 2. An adjustment groove 32 is provided between each of the three sets of horizontal fixing seats 31 and the vertical fixing seat 3. Clamping bolts 33 are slidably installed in each of the four sets of adjustment grooves 32. All four sets of clamping bolts 33 are threadedly connected to the side wall of the centering fixture base 11, thus fixing the three sets of horizontal fixing seats 31 and the vertical fixing seat 3. When the operator needs to adjust the vertical... When the position of the top seat 21 is such that the horizontal height of the three sets of horizontal top seats 2 needs to be adjusted, the clamping bolts 33 in the adjustment groove 32 can be tightened to adjust the vertical fixed seat 3 and the horizontal fixed seat 31 along the direction of the adjustment groove 32. This not only fixes the height of the fairing glass from the top of the tooling and ensures the vertical spherical deviation of the fairing glass, but also uses the dial indicator 26 to detect the spherical roundness of the fairing glass. By finely adjusting the front and rear distance of the fairing mounting plate 12, the fairing glass can be made to meet the requirement of ensuring the horizontal spherical deviation of the fairing glass when the turntable rotates.

[0025] Furthermore, a fairing mounting plate 12 is installed on the side wall of the centering fixture base 11. The fairing mounting plate 12 is threadedly connected to the side wall of the centering fixture base 11 by fixing bolts 13, which can fix one side of the fairing. A positioning ring 15 is fixedly installed on the top of the centering fixture base 11. The side wall of the positioning ring 15 corresponds to the side wall of the fairing, which can position the fairing. By placing the fairing on the top of the centering fixture base 11 and positioning it in the positioning ring 15 on the top of the centering fixture base 11, and tightening the fixing bolts 13 on the mounting plate, the top of the fairing can be supported.

[0026] It should be noted that the mandrel 14 is mounted on the turntable. By rotating the turntable, the outer circle of the mandrel is checked using a dial indicator 26. The position of the mandrel is adjusted to ensure that the runout of the outer circle is no more than 0.05 mm, so as to ensure that the coaxiality between the turntable shaft and the fairing spherical center axis is less than 0.05 mm. Then, the fairing glass can be tightened at the same height by three horizontal push rods 23. By rotating the turntable, the spherical roundness of the fairing glass is checked using a dial indicator 26. By finely adjusting the front and rear distance of the fairing mounting plate 12, the spherical runout of the fairing glass is ensured to be no more than 0.15 mm when the turntable rotates, thus ensuring the horizontal center deviation of the fairing glass.

[0027] In use, the fairing is first placed on top of the centering fixture base 11 and positioned within the positioning ring 15 on top of the centering fixture base 11. Holding one side of the centering fixture base 11, the centering shaft 14 mounted on the top of the manual turntable 1 allows the fairing inside the centering fixture base 11 to rotate horizontally. Using a dial indicator 26 to check the outer diameter of the shaft, the position of the fairing shaft can be adjusted, ensuring the coaxiality of the turntable shaft and the fairing spherical shaft. Simultaneously, tightening the four sets of push rods 23 within the positioning and detection mechanism pushes the push rods 23 inside the three sets of horizontal top seats 2 to fit against the sidewalls of the fairing, and also pushes the push rods 23 inside the vertical top seat 21 to fit against the top of the fairing, ensuring the fairing is firmly and stably positioned on top of the centering fixture base 11. This device not only achieves glass position adjustment and centering but also stabilizes the glass position during bonding, preventing concentricity errors caused by epoxy adhesive curing shrinkage. Actual measurements show… This design ensures the concentricity of the bonded fairing glass with the housing, avoiding the scratches caused by the metal housing's retaining grooves that previously plagued fairing glass. Furthermore, the design incorporates adjustment slots 32 between the three sets of horizontal mounting bases 31 and the vertical mounting base 3, with clamping bolts 33 slidably installed within each of the four adjustment slots 32. When the operator needs to adjust the position of the vertical top mount 21 or the horizontal height of the three sets of horizontal top mounts 2, the clamping bolts 33 in the adjustment slots 32 can be tightened, allowing the vertical and horizontal mounting bases 31 to be adjusted along the direction of the adjustment slots 32. This not only fixes the height of the fairing glass from the top of the fixture, ensuring the vertical spherical center deviation of the fairing glass, but also allows the use of a dial indicator 26 to detect the spherical roundness of the fairing glass. By finely adjusting the front-to-back distance of the fairing mounting plate 12, the design ensures that the fairing glass maintains the horizontal spherical center deviation when the turntable rotates.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
