Description

Technical Field

[0001] The invention relates to the field of aerospace technology, and more specifically to a bonding tool for a waist-shaped round bushing and a control panel. Background Art

[0002] The waist-shaped circular bushing is glued to the control panel with adhesive, and the tail rotor blade is connected to the control panel through the non-uniformly distributed waist-shaped circular bushing, and the control panel is connected to the tail reducer control shaft through the bolt holes distributed in the center. When the tail reducer is operated to change pitch, the cone disk drives the control panel assembly to reciprocate linear motion, and then drives the pitch change ball hinge of the tail rotor blade assembly to achieve torsional motion around the blade axis, thereby achieving the pitch change of the tail rotor blade assembly.

[0003] Therefore, the parallelism of the waist-shaped circular bushing and the height of the waist-shaped circular bushing from the bottom surface of the control panel directly affect the pitch change of the blade. Therefore, the bonding result of the waist-shaped circular bushing becomes a key issue in the pitch change function of the blade.

[0004] However, the current gluing process has different thicknesses of adhesive at various positions on the outer wall of the waist-shaped circular bushing during different operations, which leads to deviations in the gluing position of the waist-shaped circular bushing in the mounting hole of the control panel bushing. As a result, the height of the waist-shaped circular bushing from the bottom surface of the control panel after gluing cannot be guaranteed. At the same time, the current gluing process also makes it difficult to ensure the parallelism of the waist-shaped circular bushing after gluing. Summary of the invention

[0005] In view of this, the present invention proposes a bonding tool for a waist-shaped circular bushing and a control panel, which can ensure the parallelism of the waist-shaped circular bushing after bonding and the height from the bottom surface of the control panel.

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

[0007] A bonding tool for a waist-shaped circular bushing and a control panel, comprising a bonding tool base and a plurality of bonding tool bodies installed on the outer side of the upper part of the bonding tool base, the control panel is temporarily fixed in the middle of the upper part of the bonding tool base, the number of bushing mounting holes on the control panel is consistent with that of the bonding tool body, and each bushing mounting hole is respectively opposite to the position of the positioning hole opened on the upper part of the bonding tool body; the sleeve part in the waist-shaped circular bushing extends into the bushing mounting hole correspondingly, and the abutment part in the waist-shaped circular bushing is located at the control panel away from the bonding tool body one side; an L-shaped positioning plate is correspondingly installed on the upper part of each of the bonding tool bodies, and the bottom surface of the lower vertical plate of the L-shaped positioning plate away from the side of the bonding tool body is adapted to be close to the upper plane of the waist-shaped circular bushing; the end of the positioning pin is located on the side of the bonding tool body away from the operating panel, and the pin body of the positioning pin passes through the positioning hole and the inner hole of the waist-shaped circular bushing in sequence and is locked by a nut; a limit block with a circular hole in the middle is also provided between the abutting part of the nut and the waist-shaped circular bushing, and a gap is provided between the nut and the lower vertical plate of the L-shaped positioning plate.

[0008] Preferably, the control panel is fixed to the upper part of the adhesive tooling base by bolts, and the lower end of the control panel is adapted to tightly abut against the boss on the adhesive tooling base.

[0009] Preferably, the gluing tool body is fixed to the upper part of the gluing tool base by bolts, and the upper transverse plate in the L-shaped positioning plate is fixed to the upper part of the gluing tool body by bolts.

[0010] Preferably, the upper portion of the limit block is processed with an avoidance plane for avoiding the L-shaped positioning plate, and the height of the avoidance plane is not higher than the height of the upper plane of the waist-shaped circular bushing.

[0011] Preferably, the outer diameter of the limit block is larger than the outer diameter of the abutment portion in the waist-shaped circular bushing.

[0012] Preferably, the inner wall of the bushing mounting hole and the outer wall of the sleeve portion in the waist-shaped circular bushing are both glue-coated areas.

[0013] Compared with the prior art, the gluing tooling of the present invention for a waist-shaped circular bushing and a control panel can strictly control the positioning of the waist-shaped circular bushing during the gluing process, and jointly control the relative positions of the waist-shaped circular bushing and the control panel through the positioning pins, L-shaped positioning plates and limit blocks on the gluing tooling body, thereby satisfying the parallelism of the waist-shaped circular bushing after gluing and the height value from the bottom surface reference of the control panel.

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] Example:

[0028] like Figure 1-Figure 8 As shown, a bonding tool for a waist-shaped circular bushing and a control panel of the present invention comprises a bonding tool base 1 and a plurality of bonding tool bodies 2 installed on the outer side of the upper part of the bonding tool base 1.

[0029] During the binding process, Figure 2 The control panel 11 in the embodiment will be temporarily fixed to the middle of the upper part of the bonding tool base 1 according to the required angle (see Figure 3 ), the number of the bushing mounting holes 12 on the operating panel 11 is consistent with the number of the bonding tool body 2, and each bushing mounting hole 12 is respectively opposite to the positioning hole 10 opened on the upper part of the corresponding bonding tool body 2.

[0030] The sleeve portion 14 in the waist-shaped circular bushing 13 extends into the bushing mounting hole 12, and the abutment portion 15 in the waist-shaped circular bushing 13 is located on the side of the operating panel 11 away from the bonding tool body 2; an L-shaped positioning plate 3 is correspondingly installed on the upper part of each bonding tool body 2, and the bottom surface of the lower vertical plate 8 of the L-shaped positioning plate 3 away from the side of the bonding tool body 2 is adapted to be close to the upper plane 16 of the waist-shaped circular bushing 13; the end of the locating pin 4 is located on the side of the bonding tool body 2 away from the operating panel 11, and the pin body of the locating pin 4 passes through the locating hole 10 and the inner hole 17 of the waist-shaped circular bushing in turn, and then the locating pin 4 is correspondingly locked by a matching nut 5; a limit block 6 with a circular hole in the middle is also provided between the nut 5 and the abutment portion 15 of the waist-shaped circular bushing 13, and a gap is provided between the nut 5 and the lower vertical plate 8 of the L-shaped positioning plate 3.

[0031] The locating pin 4 in the present invention passes through the locating hole 10 and the inner hole 17 of the waist-shaped circular bushing in sequence. Therefore, the height value of the waist-shaped circular bushing 13 from the bottom surface reference of the control panel after gluing can be kept consistent through the axial positioning of the locating pin 4, thereby avoiding the problem of deviation in the gluing position of the waist-shaped circular bushing 13 caused by the different thickness of the adhesive on the outer wall of the waist-shaped circular bushing during different operations.

[0032] Meanwhile, during the bonding process, the bottom surface of the lower vertical plate in the L-shaped positioning plate 3 will always fit closely to the upper plane 16 of the waist-shaped circular bushing 13, thereby ensuring the parallelism of the waist-shaped circular bushing 13 after bonding.

[0033] The present invention also sets a limit block 6 between the nut 5 and the abutment portion 15 of the waist-shaped circular bushing 13. During the process of tightening the nut 5, the nut 5 will push the limit block 6 to push the waist-shaped circular bushing 13 into the bushing mounting hole 12 of the control panel 11, ensuring that the waist-shaped circular bushing 13 can also be tightly installed with the control panel 11 in the horizontal direction.

[0034] In actual operation, the control panel 11 is fixed to the upper part of the adhesive tooling base 1 by bolts, and the lower end of the control panel 11 is adapted to be tightly against the boss 7 on the adhesive tooling base 1 to prevent the control panel 11 from being displaced after installation.

[0035] More specifically, the gluing tool body 2 is fixed to the upper part of the gluing tool base 1 by bolts, and the upper horizontal plate 9 in the L-shaped positioning plate 3 is fixed to the upper part of the gluing tool body 2 by bolts.

[0036] In the embodiment of the present invention, the upper part of the limit block 6 is processed with an avoidance plane 18 for avoiding the L-shaped positioning plate 3, and the height of the avoidance plane 18 is not higher than the height of the upper plane of the waist-shaped circular bushing 13 to avoid interference with the L-shaped positioning plate 3 when the limit block 6 presses the waist-shaped circular bushing 13 to the right.

[0037] At the same time, the outer diameter of the limiting block 6 is larger than the outer diameter of the abutting portion 15 in the waist-shaped circular bushing 13, so as to ensure that the limiting block 6 can apply force evenly when pressing the waist-shaped circular bushing 13 to the right.

[0038] When the waist-shaped circular bushing 13 and the control panel 11 are glued together, the inner wall of the bushing installation hole 12 and the outer wall of the sleeve portion in the waist-shaped circular bushing 13 are both glue-coated areas.

[0039] The specific operation process of the present invention is:

[0040] 1) Fixing of the control panel:

[0041] Place the control panel 11 on the adhesive fixture base 1 at the required angle, tighten the bottom nut to fix the control panel 11;

[0042] 2) Gluing of waist-shaped round bushings:

[0043] Apply glue evenly on the inner wall of the bushing mounting hole 12 and the outer wall area of ​​the sleeve part in the waist-shaped circular bushing 13, and place the upper plane 16 of the waist-shaped circular bushing 13 upwards, install the positioning pin 4 (positioned through the axis to meet the height of the waist-shaped circular bushing from the bottom surface of the control panel) and the limit block 6, first install the nut 5 for pre-tightening, make the bottom surface of the lower vertical plate of the L-shaped positioning plate 3 contact with the upper plane 16 of the waist-shaped circular bushing 13, and then tighten the nut 5.

[0044] 3) Put the whole into the furnace for curing.
