Description

Technical Field

[0001] The present invention relates to the technical field of guide devices, and in particular to an anti-misalignment guide device for sealing shaft joints used in aircraft and a guide method. Background Art

[0002] An airplane is a heavier-than-air aircraft that has one or more engines that generate forward thrust or pull, and fixed wings on the fuselage that generate lift, and flies in the upper, middle, or lower atmosphere.

[0003] When producing and assembling aircraft parts, many parts made of new materials are needed. For example, sealing shafts made of silicon carbide ceramics are suitable for seals in aircraft and aerospace turbine engines. Compared with traditional rotating slender shafts, they are stronger and more resistant to friction. In addition, silicon carbide ceramics can effectively eliminate the influence of some chemical substances during use, which is something other materials cannot do.

[0004] When parts need to be used, they often need to be joined together, that is, two ceramic tubes of different diameters are coaxially joined together. The existing ceramic tube joining is done manually. During manual joining, the worker needs to hold the pipes of different diameters in each hand and align them, and then fix them together. When the temperature is low, the glue has poor fluidity, which easily leaves a gap at the joint of the two ceramic tubes, resulting in poor firmness. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that when the temperature is low, the glue has poor fluidity, which easily leaves a gap at the joint of two ceramic tubes and leads to poor firmness. A sealing shaft joint anti-misalignment guide device and guide method for aircraft are proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] Preferably, two slides are symmetrically provided, and a first track groove adapted to the slides is opened on the bottom plate.

[0009] In order to improve the engagement effect, preferably, the forward part includes: a push plate slidably mounted on the outer edge surface of the arc-shaped support plate, a first spring fixedly connected between the push plate and the arc-shaped support plate; a first lining plate slidably mounted on the side of the arc-shaped support plate away from the push plate, a limiting pin rotatably mounted on the first lining plate through a torsion spring; a mounting groove and a first gear rotatably mounted in the mounting groove are provided on the arc-shaped support plate, and tooth grooves matching the first gear are provided on both the push plate and the first lining plate.

[0010] In order to fix the second ceramic tube body, it further includes: a cylinder fixedly mounted on the support frame, the output end of the cylinder is fixedly mounted with a pressure rod; two symmetrically arranged second lining plates are elastically mounted in the fixed sleeve, and the pressure rod is against the upper second lining plate.

[0011] In order to cut the joined parts, preferably, it also includes: an elastic member fixedly mounted on the slide, the elastic member being rotatably connected to the arc-shaped support plate; a guide plate fixedly mounted on the base plate, the guide plate being provided with a second guide groove, and a sliding pin adapted to the second guide groove being fixedly mounted on the arc-shaped support plate.

[0012] In order to reduce the collision with parts, further, blanking plates are fixedly installed on both sides of the bottom plate, and the blanking plates are made of rubber.

[0013] In order to make the slider slide back and forth on the base plate and improve processing efficiency, it further includes: a vertical block passing through the base plate, fixedly installed with the slide seat on one side, and a rack fixedly installed on the vertical block; a coaxially arranged second gear and worm wheel, rotatably installed on the lower surface of the base plate, the second gear is meshed with the rack, a motor is fixedly installed on the base plate, and the output unit of the motor is connected to a worm through a coupling, and the worm is meshed with the worm wheel.

[0014] In order to make the slides on both sides slide alternately, further, symmetrically arranged tensioning wheels are rotatably installed on the bottom plate, and a belt is rotatably installed between the symmetrical tensioning wheels, and the two slides are fixedly installed on the belt.

[0015] In order to realize automatic unloading of the first ceramic tube body, preferably, it also includes: a material box fixedly installed on the bottom plate, a linear groove adapted to the limit pin is opened at the bottom of the material box, and a material hole for the first ceramic tube body to slide out is opened on the top of the material box.

[0016] A method for preventing misalignment of a sealed shaft joint for an aircraft, the operating steps are as follows:

[0017] Step 1: Place the two ceramic tubes to be joined opposite each other and heat one of the ceramic tubes;

[0018] Step 2: Push the ceramic tube on one side into the heated ceramic tube on the other side to achieve jointing, thereby improving the jointing effect and avoiding cracks on the ceramic tube;

[0019] Step 3: The ceramic tubes are joined using an automatic loading method to reduce manual labor.

[0020] Compared with the prior art, the present invention provides an anti-misalignment guide device and guide method for a sealed shaft joint for an aircraft, which has the following beneficial effects:

[0021] 1. The aircraft uses a sealing shaft to engage an anti-dislocation guide device. The slide seat is pushed by external force to move the first ceramic tube body toward the second ceramic tube body until the push rod on the fixed sleeve pushes the push plate. The push plate drives the first lining plate to slide in the opposite direction through the first gear, so that the limit pin on the first lining plate pushes the first ceramic tube body into the fixed sleeve to engage with the second ceramic tube body. Since the junction of the first ceramic tube body and the second ceramic tube body is located in the fixed sleeve, interference from external dust is avoided. At the same time, the heating plate keeps the temperature inside the fixed sleeve at an appropriate temperature, improves the fluidity of the glue, and greatly fills the contact surface between the first ceramic tube body and the second ceramic tube body.

[0022] 2. The aircraft uses a sealed shaft to engage an anti-dislocation guide device. When the first ceramic tube body is placed on the curved support plate, the weight of the first ceramic tube body presses the third spring down a certain distance. At this time, the sliding pin on the curved support plate slides in the straight line groove. When the first ceramic tube body and the second ceramic tube body are joined, the weight increases, pressing the third spring to continue to descend a certain distance. At this time, the sliding pin slides in the curved line groove. The curved line groove constrains the sliding pin and drives the curved support plate to flip, thereby unloading the joined parts.

[0023] 3. The aircraft uses a sealed shaft to engage the anti-misalignment guide device. The arc-shaped support plate is located below the material box at the beginning of the stroke. When the motor is working, the limit pin pushes the first ceramic tube body at the bottom of the material box to be placed on the arc-shaped support plate, realizing automatic unloading of the first ceramic tube body and improving work efficiency.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0035] Example 1:

[0036] Reference Figures 1-8 A sealing shaft joint anti-misalignment guide device for aircraft includes a base plate 1 and a support frame 2. In order to improve the compactness of the device, the support frame 2 is fixed on the base plate 1 as a whole, and also includes: a slide 3 slidably mounted on the base plate 1, an arc-shaped support plate 4 is rotatably mounted on the slide 3, a first ceramic tube body 5 is placed on the arc-shaped support plate 4, and a forward portion is elastically mounted on the arc-shaped support plate 4; a fixed sleeve 6 fixedly mounted on the support frame 2, a second ceramic tube body 7 is clamped in the fixed sleeve 6, and a heating plate 15 is fixedly mounted in the fixed sleeve 6; a push rod 8 adapted to the forward portion is fixedly mounted on the side of the fixed sleeve 6 close to the arc-shaped support plate 4.

[0037] Waterproof platforms are fixedly installed on both sides of the lower surface of the bottom plate 1, and anti-slip pads are fixedly installed on the waterproof platforms, thereby improving the overall stability of the device.

[0038] See Figure 1 and Figure 2 Furthermore, two slides 3 are symmetrically arranged, and a first track groove 101 adapted to the slides 3 is opened on the base plate 1.

[0039] See Figure 1 and Figure 2 and Figure 3 The slide 3 includes a first slider 301 that slides linearly on the base plate 1, and a second slider 302 is slidably installed on the first slider 301. An extension rod 303 is integrally installed on the second slider 302, and the arc-shaped support plate 4 is arranged on the extension rod 303. In this solution, the extension rod 303 is not fixed on the central axis of the second slider 302, but is fixed on the side of the second slider 302 close to the other second slider 302. In this way, the two arc-shaped support plates 4 will be on the same axis with the fixed sleeve 6 at the end of the stroke.

[0040] The extension line of the sliding direction of the second slider 302 and the extension line of the sliding direction of the first slider 301 form an angle of 90°.

[0041] It should be noted that the first track groove 101 includes straight line grooves at both ends and a transition line groove connecting the two straight line grooves together. A sliding rod 102 is also slidably installed in the first track groove 101 to control the sliding of the second slider 302, so that the arc-shaped support plate 4 on the second slider 302 is finally located on the same axis as the fixed sleeve 6.

[0042] During the joining, the first ceramic tube body 5 is placed on the arc-shaped support plate 4, and the second ceramic tube body 7 is placed in the fixed sleeve 6. The slide seat 3 is pushed by external force to move the first ceramic tube body 5 toward the side of the second ceramic tube body 7 until the push rod 8 on the fixed sleeve 6 pushes the forward part, so that the forward part pushes the first ceramic tube body 5 to continue to extend into the second ceramic tube body 7 and join with it.

[0043] During bonding, the joint of the first ceramic tube body 5 and the second ceramic tube body 7 is located inside the fixing sleeve 6 to avoid interference from external dust. At the same time, the heating plate 15 keeps the temperature inside the fixing sleeve 6 at an appropriate temperature, improves the fluidity of the glue, and greatly fills the contact surface between the first ceramic tube body 5 and the second ceramic tube body 7.

[0044] See Figure 3 and Figure 7 , the forward part in this embodiment is further optimized,

[0045] The forward part includes: a push plate 9 slidably mounted on the outer edge surface of the arc-shaped support plate 4, a first spring 10 fixedly connected between the push plate 9 and the arc-shaped support plate 4; a first lining plate 11 slidably mounted on the side of the arc-shaped support plate 4 away from the push plate 9, a limiting pin 12 is rotatably mounted on the first lining plate 11 through a torsion spring; a mounting groove 401 and a first gear 13 rotatably mounted in the mounting groove 401 are provided on the arc-shaped support plate 4, and a tooth groove 14 matching the first gear 13 is provided on the push plate 9 and the first lining plate 11.

[0046] When the push rod 8 pushes the push plate 9, the push plate 9 drives the first lining plate 11 to slide in the opposite direction through the first gear 13, so that the limit pin 12 on the first lining plate 11 pushes the first ceramic tube body 5 into the fixing sleeve 6 to engage with the second ceramic tube body 7.

[0047] See Figure 1 and Figure 4 The aircraft sealed shaft joint anti-misalignment guide device in this embodiment also includes: a cylinder 16 fixedly mounted on the support frame 2, and a pressure rod 17 fixedly mounted on the output end of the cylinder 16; two symmetrically arranged second lining plates 18 are elastically mounted in the fixed sleeve 6, specifically, a second spring 27 is fixedly connected between the second lining plate 18 and the inner wall of the fixed sleeve 6, and the pressure rod 17 is against the second lining plate 18 above.

[0048] During the operation of the cylinder 16 , the output end of the cylinder 16 presses the second lining plate 18 above through the pressure rod 17 , so that the second lining plate 18 clamps the second ceramic tube body 7 in the fixing sleeve 6 to reduce the shaking of the second ceramic tube body 7 .

[0049] In general, when joining the first ceramic tube body 5 and the second ceramic tube body 7, the first ceramic tube body 5 is placed on the arc-shaped support plate 4, and the second ceramic tube body 7 is manually placed in the fixed sleeve 6. The slide seat 3 is pushed by external force to move the first ceramic tube body 5 toward the side of the second ceramic tube body 7 until the push rod 8 on the fixed sleeve 6 pushes the push plate 9. The push plate 9 drives the first lining plate 11 to slide in the opposite direction through the first gear 13, so that the limit pin 12 on the first lining plate 11 pushes the first ceramic tube body 5 into the fixed sleeve 6 to join with the second ceramic tube body 7. Since the joint of the first ceramic tube body 5 and the second ceramic tube body 7 is located in the fixed sleeve 6, interference from external dust is avoided. At the same time, the heating plate 15 keeps the temperature inside the fixed sleeve 6 at an appropriate temperature at all times, improves the fluidity of the glue, and greatly fills the contact surface of the first ceramic tube body 5 and the second ceramic tube body 7.

[0050] Example 2:

[0051] See Figures 1-8 , which is basically the same as Example 1. On the basis of Example 1, the entire technical solution is further optimized.

[0052] See Figure 1 and Figure 6 and Figure 7 To facilitate material removal, the aircraft seal shaft joint anti-misalignment guide device of this embodiment further includes: an elastic member 28 fixedly mounted on the slide 3; the elastic member 28 is rotatably connected to the arc-shaped support plate 4; a guide plate 26 fixedly mounted on the base plate 1, the guide plate 26 having a second guide groove 2601 formed therein. The second guide groove 2601 is provided with two grooves: a straight groove and an arc-shaped groove located below the straight groove; and a sliding pin 2602 fixedly mounted on the arc-shaped support plate 4, adapted to fit the second guide groove 2601.

[0053] It should be noted that the elastic member 28 includes a sleeve 2801 fixedly mounted on the slide 3, a telescopic rod 2802 is slidably mounted in the sleeve 2801, and the end of the telescopic rod 2802 away from the sleeve 2801 is rotatably mounted together with the arc support plate 4, and a third spring 2803 is sleeved on the telescopic rod 2802, and the two ends of the third spring 2803 are respectively fixedly mounted on the sleeve 2801 and the arc support plate 4.

[0054] When the first ceramic tube body 5 is placed on the arc-shaped support plate 4, the weight of the first ceramic tube body 5 presses the third spring 2803 to drop a certain distance. At this time, the sliding pin 2602 on the arc-shaped support plate 4 slides in the straight line groove. When the first ceramic tube body 5 and the second ceramic tube body 7 are connected, the weight increases, pressing the third spring 2803 to continue to drop a certain distance. At this time, the sliding pin 2602 slides in the arc-shaped line groove. The arc-shaped line groove constrains the sliding pin 2602 to drive the arc-shaped support plate 4 to flip, and the connected parts are unloaded.

[0055] See Figure 1 and Figure 2 Furthermore, blanking plates 29 are fixedly installed on both sides of the bottom plate 1, and the blanking plates 29 are made of rubber.

[0056] The blanked parts come into contact with the flexible blanking plate 29, thus avoiding rigid collision and effectively preventing the joint from being disconnected again.

[0057] Example 3:

[0058] See Figures 1-8 , which is basically the same as Example 2. On the basis of Example 2, the entire technical solution is further optimized.

[0059] See Figure 2 and Figure 3 and Figure 8 In order to save manpower, the aircraft sealed shaft joint anti-misalignment guide device of this embodiment also includes: a vertical block 19 penetrating the base plate 1, fixedly mounted on one side of the slide 3, and a rack 20 fixedly mounted on the vertical block 19; a coaxially arranged second gear 21 and a worm gear 22, rotatably mounted on the lower surface of the base plate 1, the second gear 21 meshingly connected to the rack 20; a motor 31 fixedly mounted on the base plate 1, the output of the motor 31 connected to the worm 23 via a coupling, and the worm 23 meshingly connected to the worm gear 22.

[0060] During operation of the motor 31, the output end of the motor 31 rotates the worm 23 through the coupling. The rotating worm 23 rotates the meshing worm wheel 22, which transmits the rotational force to the second gear 21, causing the second gear 21 to move the meshing rack 20.

[0061] It should be noted that two second gears 21 are provided, and a notched gear 2101 is fixedly mounted on each of the two second gears 21 , so that the rack 20 can move back and forth on the base plate 1 .

[0062] See Figure 2 Furthermore, a symmetrically arranged tensioning wheel 24 is rotatably mounted on the base plate 1 , a belt 25 is rotatably mounted between the symmetrical tensioning wheels 24 , and both slides 3 are fixedly mounted on the belt 25 .

[0063] The belt 25 is used to receive the force transmitted from the rack 20 and drive the slides 3 on both sides to move alternately toward the fixing sleeve 6 .

[0064] Example 4:

[0065] See Figures 1-8 , which is basically the same as Example 3. On the basis of Example 3, the entire technical solution is further optimized.

[0066] See Figure 1 and Figure 2 and Figure 5 In order to achieve automatic loading, the aircraft sealing shaft joint anti-dislocation guide device of this embodiment also includes: a material box 30 fixedly mounted on the base plate 1, with a linear groove 3001 adapted to the limit pin 12 formed in the bottom of the material box 30, and a material hole 3002 for the first ceramic tube body 5 to slide out.

[0067] The arc-shaped support plate 4 is located below the material box 30 at the beginning of the stroke. When the motor 31 is working, the limit pin 12 pushes the first ceramic tube body 5 at the bottom of the material box 30 to be placed on the arc-shaped support plate 4, realizing automatic unloading of the first ceramic tube body 5.

[0068] It should be noted that since the limit pin 12 is rotatably mounted on the first liner 11 via a torsion spring, the limit pin 12 will only rotate toward the side away from the material box 30 to prevent the limit pin 12 from being stuck when passing through the material box 30.

[0069] A method for preventing misalignment of a sealed shaft joint for an aircraft, the operating steps are as follows:

[0070] Step 1: Place the first ceramic tube body 5 on the arc-shaped support plate 4, and manually place the second ceramic tube body 7 in the fixing sleeve 6, and the fixing sleeve 6 heats the second ceramic tube body 7 inside;

[0071] Step 2: Start the motor 31. The output end of the motor 31 rotates the worm 23 through the coupling. The rotating worm 23 rotates the meshing worm wheel 22. The rotating worm wheel 22 transmits the rotational force to the second gear 21, causing the second gear 21 to move the meshing rack 20, causing the slide 3 to move toward the side of the fixed sleeve 6.

[0072] Step 3: Until the push rod 8 on the fixed sleeve 6 pushes the push plate 9, the push plate 9 drives the first lining plate 11 to slide in the opposite direction through the first gear 13, so that the limit pin 12 on the first lining plate 11 pushes the first ceramic tube body 5 into the fixed sleeve 6 to engage with the second ceramic tube body 7. Since the junction of the first ceramic tube body 5 and the second ceramic tube body 7 is located in the fixed sleeve 6, interference from external dust is avoided. At the same time, the heating plate 15 keeps the temperature inside the fixed sleeve 6 at an appropriate temperature, improves the fluidity of the glue, and greatly fills the contact surface between the first ceramic tube body 5 and the second ceramic tube body 7.

[0073] Step 4: After the first ceramic tube body 5 and the second ceramic tube body 7 are joined, the weight increases, pressing the third spring 2803 to continue to descend a certain distance. At this time, the sliding pin 2602 slides in the arc groove. The arc groove constrains the sliding pin 2602 to drive the arc support plate 4 to flip and unload the joined parts.

[0074] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
