Description

[0002] With the unique characteristics of light weight, high specific strength and specific stiffness, excellent fatigue resistance, impact resistance and strong designability of functional honeycombs and PMI foam sandwich structures made of composite materials, they are widely used in the fields of aviation, aerospace, etc.

[0003] In the manufacturing process of functional honeycomb and PMI foam sandwich structure composite parts, methods such as vacuum bag hot curing and autoclave hot curing are adopted. Due to reasons such as prepreg layup, material self - characteristics, overall structure form, and curing thermal deformation, the material structure will deform. When some materials, such as white honeycombs, are processed into absorbing honeycomb functional materials through secondary processing, due to the complex design of aviation functional honeycombs, they are prone to deformation during curing. Some will cause the honeycomb node glue to be pulled apart and torn. At the same time, because honeycombs are anisotropic materials, curing according to a rectangle will produce single - curvature and double - curvature torsional deformations. The deformed honeycomb materials cannot be machined on a machine tool. This results in a low yield rate, affects the product delivery schedule, and has poor economic effects.

[0029] A functional honeycomb repair and shaping tooling, also known as a functional honeycomb repair and shaping device, see Figures 1 to 5, The functional honeycomb repair and shaping tooling includes a frame body 1, a fixture 2, multiple sets of connecting components 3 and an adjustment component 4. The frame body 1 includes an upper frame body and a lower frame body. The fixture 2 is located between the upper frame body and the lower frame body. The fixture 2 includes an upper fixture and a lower fixture. The functional honeycomb to be repaired is located between the upper fixture and the lower fixture. A part of the connecting component 3 sequentially penetrates through the upper frame body, the upper fixture, the lower fixture and the lower frame body to connect the frame body 1 and the fixture 2 and fix the fixture 2. The adjusting member 41 is located between the upper fixture and the upper frame body and between the lower fixture and the lower frame body, and the lengths of the adjusting members 41 at different positions are different.

[0030] The frame body 1 mainly plays a role in supporting and connecting. Through multiple sets of connecting components 3, the frame body 1, the fixture 2 and the honeycomb structure 6 to be corrected are connected. The honeycomb structure to be corrected is clamped by the upper fixture and the lower fixture; the fixture 2 is fixed by the upper frame body and the lower frame body to realize the overall installation of the tooling.

[0031] The shape of the frame body 1 is not limited to the rectangular hollowed-out plate structure in the figure. Its structure is only for clamping the edge of the honeycomb curing, so that the warm air can flow inside the honeycomb hole wall during the curing of the functional honeycomb, so that it can be cured. Therefore, it can also be a whole plate, a plate with cut circular holes or any other shape; the material is made of 304 stainless steel, high-strength steel, etc.

[0032] The shape of the fixture 2 is not limited to the rectangular hollowed-out plate structure in the figure. Its structure is only for clamping the edge of the honeycomb curing, so that the warm air can flow inside the honeycomb hole wall during the curing of the functional honeycomb, so that it can be cured. Therefore, it can also be a uniform plate, a plate with circular holes or any other shape; the material is made of 304 stainless steel, high-strength steel, etc. Its thickness is less than that of the frame body 1, which is easy to deform under the adjustment of the later adjusting member 41.

[0033] The overall honeycomb structure 6 to be corrected has a certain curvature. During the clamping process, the honeycomb structure 6 is bent in the opposite direction by the fixture 2, so as to correct the honeycomb structure 6. The lengths of the adjusting members 41 are different, and the adjusting members 41 with different lengths are at different positions, so that the overall fixture 2 is bent to facilitate the correction of the honeycomb structure 6.

[0034] The honeycomb structure 6 is corrected by the reverse bending of the fixture 2, and the bending degree of the fixture 2 is adjusted and controlled by the different lengths of the adjusting members 41 to adapt to different honeycomb structures 6. By pre-shaping the honeycomb, the machining amount of the honeycomb can be reduced, the machining time can be saved, the comprehensive production cost can be saved, and at the same time, the adjustment and shaping of the honeycomb surface with multiple cover curvatures can be satisfied.

[0035] Further, the connecting component 3 includes a connecting bolt 21, a first connecting nut 22 and a second connecting nut 23. The connecting bolt 21 passes through the upper frame body, the upper fixture, the lower fixture and the lower frame body; the connecting bolt 21 is threadedly connected with the first connecting nut 22, and the first connecting nut 22 abuts against the upper frame body or the lower frame body; the connecting bolt 21 is threadedly connected with the second connecting nut 23, and the second connecting nut 23 abuts against the fixture 2.

[0036] The bolt passes through the upper frame body, the upper fixture, the lower fixture and the lower frame body to achieve the preliminary connection between the frame body 1 and the fixture 2. Then, through the first nut, the upper frame body and the lower frame body are fixed. Then, through the second nut, the connection between the lower fixture and the upper fixture and the frame body 1 is achieved, so as to realize the connection and installation between the frame body 1 and the fixture 2. Connecting the frame body 1 and the fixture 2 by bolts and nuts facilitates the installation and disassembly of the frame body 1 and the fixture 2.

[0037] Further, the adjusting member 41 is an adjusting sleeve, and the adjusting sleeve is sleeved on the connecting bolt 21.

[0038] The adjusting sleeve is directly sleeved on the connecting bolt 21, and then the first connecting nut 22 or the second connecting nut 23 is installed, which is convenient for installation and disassembly.

[0039] In this embodiment, the adjusting assembly 4 further includes a support member 42, and the support member 42 is located between the adjusting sleeve and the fixture 2.

[0040] Further, the support member 42 includes a connecting portion 421 and a supporting portion 422. The connecting portion 421 is sleeved on the connecting bolt 21; the supporting portion 422 is fixed at one end of the connecting portion 421 close to the fixture 2, and one side of the supporting portion 422 close to the fixture 2 is a curved surface adapted to the surface of the fixture 2.

[0041] During the correction process, in order to ensure the correction effect of the fixture 2 on the honeycomb structure 6, the force balance of the fixture 2 needs to be ensured. Since the fixture 2 is a curved surface, the supporting portion 422 of the support member 42 in contact with the fixture 2 cooperates with the curved surface of the fixture 2, reducing the dispersion of forces in other directions, thereby ensuring the force balance of the fixture 2 and ensuring the correction effect on the honeycomb structure 6.

[0042] In this embodiment, the connecting bolt 21 has a scale mark 211 with a groove structure.

[0043] By reading the scale markings of the fixture 2 at different positions on the connecting bolt 21, the curvature of the fixture 2 can be conveniently calculated to prevent the situation of insufficient or excessive curvature. The scale mark 211 of the groove can reduce the wear of the scale mark 211 during the repeated adjustment and installation and disassembly of the fixture 2, increasing its service life.

[0044] In this embodiment, as Figure 2As shown in the figure, a long hole 11 is formed in the frame body 1. The extending direction of the long hole 11 is the same as the length direction of the side where it is located. The connecting component 3 penetrates through the upper frame body and the lower frame body through the long hole 11.

[0045] During the correction process of the honeycomb structure 6, since the fixture 2 and the honeycomb structure 6 in the initial state are in a bent state, as the correction process progresses, they will gradually tend to be horizontal, which will change the length of the fixture 2. By setting the long hole 11, a reserved space can be provided for the movement of the fixture 2 after the length change, avoiding the situation where the fixture 2 cannot be unfolded and improving the correction effect on the honeycomb structure 6.

[0046] Furthermore, the adjustment component 4 further includes an auxiliary fixing component 5. The auxiliary fixing component 5 includes an auxiliary bolt 51 and an auxiliary nut 52. The auxiliary bolt 51 penetrates through the upper fixture and the lower fixture; the auxiliary nut 52, and the auxiliary nut 52 is threadedly connected with the auxiliary bolt 51, and the auxiliary nut 52 abuts against the upper fixture or the lower fixture.

[0047] The auxiliary fixing component 5 performs auxiliary fixing on the honeycomb structure 6 located on the fixture 2, so that the fixture 2 at different positions can be attached to the honeycomb structure 6, thereby improving the correction effect on the honeycomb structure 6.

[0048] Furthermore, the auxiliary fixing component 5 is located between two adjacent connecting components 3.

[0049] The connecting component 3 can play a role in connecting the fixture 2 and the honeycomb structure 6. However, the connection between the fixture 2 and the honeycomb structure 6 between the two connecting components 3 is relatively weak. Therefore, by setting the auxiliary fixing component 5 here, the clamping effect of the fixture 2 on the honeycomb structure 6 at this place can be improved, thereby improving the correction effect on the honeycomb structure 6.

[0050] Furthermore, the auxiliary fixing component 5 further includes an elastic member 53, and the elastic member 53 is located between the auxiliary nut 52 and the fixture 2.

[0051] The elastic member 53 can play a role in buffering and clamping. During the process of adjusting the curved surface, the fixture 2 will not suddenly become loose, which is convenient for the adjustment of the fixture 2.

[0052] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0053] 1. The overall honeycomb structure 6 to be corrected has a certain curvature. During the clamping process, the honeycomb structure 6 is bent in the opposite direction through the fixture 2, so as to correct the honeycomb structure 6. The lengths of the adjusting members 41 are different, and the adjusting members 41 of different lengths are at different positions, so that the overall fixture 2 is bent to facilitate the correction of the honeycomb structure 6.

[0054] 2. The bolt passes through the upper frame body, the upper fixture, the lower fixture and the lower frame body to achieve the preliminary connection between the frame body 1 and the fixture 2. Then, through the first nut, the fixation of the upper frame body and the lower frame body is achieved. And through the second nut, the connection between the lower fixture and the upper fixture and the frame body 1 is achieved, thus realizing the connection and installation between the frame body 1 and the fixture 2. Connecting the frame body 1 and the fixture 2 by bolts and nuts facilitates the installation and disassembly of the frame body 1 and the fixture 2.

[0055] 3. The auxiliary fixing component 5 auxiliarily fixes the honeycomb structure 6 located on the fixture 2, so that the fixtures 2 at different positions can be attached to the honeycomb structure 6, thereby improving the correction effect on the honeycomb structure 6.
