Description

Technical Field

[0001] The present invention belongs to the technical field of three-dimensional weaving, and in particular relates to a three-dimensional weaving integrated molding device and method for an aviation composite sandwich structure blade. Background Art

[0002] The aviation composite sandwich structure is woven onto the surface of the blade body through a three-dimensional weaving method. Compared with laminated composite materials, the aviation composite sandwich structure is a "sandwich" structure formed by high-strength panels (skins) and lightweight core materials through gluing or curing processes. It combines lightweight, high strength and excellent functionality.

[0003] The current 3D braiding machine is open at both ends. When the blade body is manually held into the 3D braiding machine, the blade body will shake greatly during the braiding process, and the blade body cannot correspond to the center of the 3D braiding machine, affecting the braiding quality.

[0004] Therefore, it is necessary to invent a three-dimensional braided integral molding device and method for aviation composite sandwich structure blades to solve the above problems. Summary of the Invention

[0005] In response to the above problems, the present invention provides a device and method for three-dimensional braided integral molding of aviation composite sandwich structure blades to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A three-dimensional weaving integrated molding device for an aviation composite sandwich structure blade, comprising: a three-dimensional weaving machine, used to weave the weaving material on the surface of a moving object; a centering component comprising: a clamping component, used to clamp the object and make the object correspond to the center of the three-dimensional weaving machine; a moving frame, used to move the clamping component so that the object is close to or away from the three-dimensional weaving machine; a rotating component comprising: a pushing component, used to push the clamping component to move, so that the clamping component is close to or away from the object; a V-shaped frame, connected to the pushing component, and the clamping component rotates on the inside of the V-shaped frame using the pushing component; a push rod, connected to the V-shaped frame and externally connected to a power component, and the power component provides moving power to the pushing component through the push rod and the V-shaped frame.

[0007] Furthermore, the clamping component includes: two clamping frames for clamping objects, and the clamping frames include a first slider and a second slider; a tilting frame, and the pushing component adjusts the distance between the first slider and the second slider through the tilting frame; and a locking component for locking the first slider and the second slider on the surface of the tilting frame.

[0008] Furthermore, the locking component enables the insertion rod to lock the first slider and the second slider under the pressure of the screw sleeve.

[0009] Furthermore, the rear sides of the first slider and the second slider are both connected with clamping rods for clamping objects, and both clamping frames clamp objects using the clamping rods.

[0010] Furthermore, the pushing component includes: a connecting column, the first slider and the second slider both slide on the surface of the connecting column using a locking component; and a side plate that is rotatably sleeved on the inner side of the V-shaped frame.

[0011] Furthermore, a rotation groove corresponding to the inner side of the V-shaped frame is opened at the center of the side plate, and the clamping frame rotates on the inner side of the V-shaped frame through the side plate of the pushing component.

[0012] Furthermore, a limiting component for limiting excessive rotation of the rotating component is provided on the outer side of the side plate, and the limiting component includes: a bent plate passing through the V-shaped frame; and a first elastic member connected to the bent plate to provide resistance to the rotation of the bent plate.

[0013] The present invention also provides a method for three-dimensional braiding and integrated molding of an aviation composite material sandwich structure blade. The method uses the above-mentioned three-dimensional braiding and integrated molding device for an aviation composite material sandwich structure blade, and comprises the following steps:

[0014] S1. Place the object at the center of the rear side of the clamping component. The power component moves the pushing component through the push rod and the V-shaped frame. The pushing component pushes the clamping component close to the object to complete the clamping of the object, so that the object corresponds to the center of the three-dimensional weaving machine; S2. Push the movable frame backward. The moving movable frame uses the clamping component to bring the object close to the three-dimensional weaving machine until the clamping component moves backward at the center of the three-dimensional weaving machine. The three-dimensional weaving machine weaves the weaving material on the surface of the moving object; S3. A centering component is also installed on the rear side of the three-dimensional weaving machine. When the object carrying the weaving material moves to the center of the centering component on the rear side, the clamping component on the front side of the three-dimensional weaving machine releases the object, and the centering component on the rear side clamps the object carrying the weaving material and pulls the object carrying the weaving material out of the center of the three-dimensional weaving machine to complete the three-dimensional weaving one-piece molding process of the object.

[0015] The technical effects and advantages of the present invention are as follows:

[0016] 1. The present invention uses the power of the power component to make the clamping rod on the rear side of the clamping frame approach the object. The irregular object causes the clamping frame to rotate, and the first elastic member provides resistance to the rotation of the bending plate. When the four clamping rods all contact the object using the rotating sleeve, the object corresponds to the center of the center ring. After the moving frame brings the object into the three-dimensional braiding machine, it avoids the yarn from being unevenly woven on the surface of the object due to the deviation of the object.

[0017] 2. The present invention enables the first slider and the second slider to move closer to or farther away from each other through the movement of the clamping frame. The first slider and the second slider both move on the surface of the connecting column through the two frame plates. The elastic force of the second elastic member is used to limit the movement of the first slider and the second slider, thereby preventing the first slider and the second slider from moving too fast, and facilitating the clamping frame that moves too fast to drive the clamping rod to impact the surface of the object.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example 1:

[0026] In the embodiment, Figure 1 As a standard, the moving frame 2 is located at the front side of the three-dimensional braiding machine 1 .

[0027] The present invention provides a three-dimensional braided integral molding device for aviation composite sandwich structure blades, such as Figure 1 and Figure 2As shown, it includes a three-dimensional braiding machine 1, which is configured as a ring structure as a whole. A center ring 101 is provided at the center of the front side and the rear side of the three-dimensional braiding machine 1, and both sides of the three-dimensional braiding machine 1 are connected to a base plate 102 by means of brackets. The two brackets enable the three-dimensional braiding machine 1 to be placed vertically.

[0028] Specifically, a plurality of winding spindles 103 are provided at the center of the three-dimensional braiding machine 1, and yarns are pulled out from the output ends of the winding spindles 103. The yarns at the output ends of the plurality of winding spindles 103 are woven onto the surface of a moving object, wherein the object is set as a blade body.

[0029] In this embodiment, centering components are installed on the front and rear sides of the three-dimensional braiding machine 1. The centering component on the front side sends the object into the interior of the three-dimensional braiding machine 1 through the central ring 101 on the front side. When the object carrying the braided material is moved out of the three-dimensional braiding machine 1 from the central ring 101 on the rear side, the centering component on the front side of the three-dimensional braiding machine 1 releases the object, and the centering component on the rear side clamps the object carrying the braided material and pulls the object carrying the braided material out of the center of the three-dimensional braiding machine 1, completing the three-dimensional braiding integrated molding process of the object.

[0030] In order to define the object, the centering component is used to complete the positioning of the object. Figure 1 and Figure 3 In the figure, the centering components include: a clamping component, a mobile frame 2, and a rotating component. The mobile frame 2 is located at the front side of the three-dimensional braiding machine 1. Side bars 201 are fixed to the bottom of both sides of the mobile frame 2, and a sliding bar 104 is fixed to the top surface of the bottom plate 102. The two side bars 201 correspond to the two sliding bars 104 one by one. The side bars 201 are slidably connected to the surface of the sliding bar 104. When the mobile frame 2 moves, the mobile frame 2 slides on the surface of the sliding bar 104 using the side bars 201. After the clamping component clamps the object, the moving mobile frame 2 uses the clamping component to bring the object closer to or away from the three-dimensional braiding machine 1. A side frame 202 is provided on the rear side of the mobile frame 2. The clamping component and the rotating component are both mounted on the side frame 202 of the mobile frame 2.

[0031] When the clamping component is used to clamp an object, the clamping component includes: two clamping frames, a tilting frame 7 and a locking component, wherein the clamping frame includes a first slider 5 and a second slider 6, and the four corners of the side frame 202 are fixed with tilting frames 7, the two top tilting frames 7 correspond one-to-one to the two first sliders 5, and the two bottom tilting frames 7 correspond one-to-one to the two second sliders 6, the first slider 5 and the second slider 6 are both set, and the first slider 5 is at the top of the second slider 6, the front side surfaces of the first slider 5 and the second slider 6 are fixed with a protruding rod 15, and a sliding groove corresponding to the protruding rod 15 is provided at the center of the tilting frame 7, and a circular plate is fixed to the front end of the protruding rod 15, the diameter of the circular plate is larger than the width of the sliding groove, and the protruding rod 15 slides inside the sliding groove of the tilting frame 7.

[0032] exist Figures 3 to 5 In the embodiment, the rear side surfaces of the first slider 5 and the second slider 6 are both fixed with a clamping rod 10, and the surface of the clamping rod 10 is sleeved with a rotating sleeve 16. When the two clamping frames approach each other, the protruding rod 15 slides inside the slide groove. Since the tilting frame 7 is tilted, the moving clamping frame brings the first slider 5 and the second slider 6 closer to each other. The clamping frame drives the clamping rod 10 to approach the object until the outer side surface of the rotating sleeve 16 fits the surface of the object. If the object has an irregular shape, the rotating sleeve 16 will slide on the surface of the object. The reaction force of the object on the clamping rod 10 causes the clamping component to rotate. At this time, the clamping frame uses the protruding rod 15 to slide inside the slide groove until the object corresponds to the center of the center ring 101. The clamping frame is limited by the locking component to prevent the clamping frame from rotating, thereby completing the clamping of the object.

[0033] In order to lock the clamping frame, the first slider 5 and the second slider 6 are defined by the locking member. Figure 4 and Figure 5 In the embodiment, the locking component includes: a screw sleeve 8 and an insertion rod 9. Two frame plates 17 are fixed to the bottom of the front side of the first slider 5 and the top of the front side of the second slider 6. At this time, the pushing component slides between the two frame plates 17. Two opposite arc-shaped plates 171 are fixed to the outer side of the frame plate 17. The insertion rod 9 is located between the two arc-shaped plates 171. The inner end of the insertion rod 9 passes through the center of the side of the frame plate 17, and the outer side of the circumference of the insertion rod 9 fits with the inner concave surface of the arc-shaped plate 171. The outer side of the circumference of the two arc-shaped plates 171 is provided with threads. The screw sleeve 8 is spirally sleeved on the outer side of the circumference of the two arc-shaped plates 171. An inner rod 172 is embedded in the center of the arc-shaped plate 171, and a second elastic member 173 is sleeved on the surface of the inner rod 172. The second elastic member 173 is set as a spring, and the top and bottom of the outer end of the insertion rod 9 are fixed with side edges 174. The side edges 174 are slidably sleeved on the surface of the inner rod 172. One end of the second elastic member 173 is connected to the side edge 174, and the other end of the second elastic member 173 is connected to the frame plate 17. The second elastic member 173 is in a stretched state. When the clamping frame needs to be moved, the first slider 5 and the second slider 6 move on the surface of the pushing component, wherein the pushing component includes: a connecting column 11 and a side plate 12. The side of the connecting column 11 is connected to the side plate 12 by a connecting rod. The connecting column 11 is vertically arranged, and the top end of the connecting column 11 is located at the front side of the first slider 5, and the bottom end of the connecting column 11 is located at the front side of the second slider 6.

[0034] In this embodiment, when the clamping frame approaches the object, the protruding rod 15 moves inside the sliding groove of the inclined frame 7, the two adjacent protruding rods 15 approach each other, the first slider 5 and the second slider 6 gradually approach each other, the first slider 5 uses the two frame plates 17 to move down on the surface of the connecting column 11, and the second slider 6 uses the two frame plates 17 to move up on the surface of the connecting column 11; when the clamping frame moves away from the object, the protruding rod 15 moves inside the sliding groove of the inclined frame 7, the two adjacent protruding rods 15 move away from each other, the first slider 5 and the second slider 6 gradually move away, the first slider 5 uses the two frame plates 17 to move up on the surface of the connecting column 11, and the second slider 6 uses the two frame plates 17 to move down on the surface of the connecting column 11.

[0035] When the first slider 5 and the second slider 6 are moved closer to or farther away from each other through the movement of the clamping frame, the first slider 5 and the second slider 6 are both moved on the surface of the connecting column 11 through the two frame plates 17. Since the second elastic member 173 is in a stretched state, the elastic force of the second elastic member 173 acts on the insertion rod 9 through the side 174. At this time, the inner end of the insertion rod 9 is in contact with the surface of the connecting column 11. The elastic force of the second elastic member 173 is used to limit the movement of the first slider 5 and the second slider 6, avoiding the first slider 5 and the second slider 6 from moving too fast, so that the clamping frame that moves too fast can drive the clamping rod 10 to impact the surface of the object.

[0036] Specifically, when the multiple clamping rods 10 on the rear side of the two clamping frames complete the clamping of the object, the screw sleeve 8 is screwed, and the screw sleeve 8 rotates on the surface of the two arc-shaped plates 171. The rotating screw sleeve 8 squeezes the outer side of the side 174, and the spiral cooperation between the screw sleeve 8 and the arc-shaped plate 171 makes the inner end of the insertion rod 9 tightly squeeze the connecting column 11. The squeezing of the insertion rod 9 prevents the first slider 5 and the second slider 6 from moving. At this time, the protruding rod 15 cannot move inside the slide groove, completing the clamping limitation of the object.

[0037] When the two clamping frames use the clamping rod 10 to clamp the object, due to the irregular shape of the object, when the clamping rod 10 contacts the object using the rotating sleeve 16, the object exerts a reaction force on the clamping rod 10 to cause the clamping frame to rotate. The clamping frame rotates using the rotating component. Figure 1 、 Figure 3 and Figure 4 In the figure, the rotating component includes: a pushing component, a V-shaped frame 3, a push rod 4 and a power component. The overall shape of the V-shaped frame 3 is set to be V-shaped, and the opening direction of the V-shaped frame 3 is set horizontally, and the opening position is far away from the connecting column 11. The inner end of the push rod 4 is connected to the center of the opening of the V-shaped frame 3, and the outer end of the push rod 4 is connected to the output end of the power component. The power component is installed on the outer side of the side frame 202, and the push rod 4 passes through the center of the side frame 202. A ring 301 is fixed to the inner side of the V-shaped frame 3, and a rotating groove corresponding to the ring 301 is opened at the center of the side plate 12. A rotating rod is set inside the rotating groove, and the ring 301 is sleeved on the surface of the drill pipe. The power component is set to a cylinder 401.

[0038] In this embodiment, when the power component operates to cause the push rod 4 to approach the object, the push rod 4 and the V-shaped frame 3 are arranged horizontally. The moving push rod 4 causes the clamping frame to approach the object through the V-shaped frame 3 and the pushing component until the clamping rod 10 contacts the object using the rotating sleeve 16. The object then exerts a reaction force on the clamping rod 10, causing the clamping frame to rotate. Specifically, when the clamping rod 10 on the rear side of the first slider 5 first contacts the object, the object causes the first slider 5 to move in the opposite direction, and the two shelf plates 17 on the front side of the first slider 5 move up on the surface of the connecting column 11. The rotating clamping frame also causes the two shelf plates 17 on the front side of the second slider 6 to move up on the surface of the connecting column 11 until the clamping rod 10 on the rear side of the second slider 6 is in contact with the surface of the object using the rotating sleeve 16. Similarly, when the clamping rod 10 on the rear side of the second slider 6 first contacts the object, the object causes the second slider 6 to move in the opposite direction, and the two shelf plates 17 on the front side of the second slider 6 move down on the surface of the connecting column 11. The rotating clamping frame also causes the two shelf plates 17 on the front side of the first slider 5 to move down on the surface of the connecting column 11 until the clamping rod 10 on the rear side of the first slider 5 is attached to the surface of the object using the rotating sleeve 16.

[0039] In order to prevent the rotating parts from over-rotating, the rotating parts are limited by limiting components. Figure 3 and Figure 4 In the figure, the limiting components include: a bent plate 13 and a first elastic member 14. The first elastic member 14 is set as a spring sheet. The bent plates 13 are fixed to the top and bottom of the outer side of the side plate 12. The two bent plates 13 correspond to the two side strips of the V-shaped frame 3 one by one. The bent plates 13 pass through the side strips of the V-shaped frame 3, and the outer ends of the bent plates 13 are connected to the push rod 4 using the first elastic member 14.

[0040] Specifically, when the rotating component rotates, it rotates on the surface of the collar 301 using the rotation groove of the side plate 12. When the top curved plate 13 approaches the push rod 4, the top curved plate 13 squeezes the top first elastic member 14, while the bottom curved plate 13 pulls the bottom first elastic member 14. When the top curved plate 13 moves away from the push rod 4, the top curved plate 13 pulls the top first elastic member 14, while the bottom curved plate 13 presses the bottom first elastic member 14. When the outer surface of the side plate 12 abuts the inner surface of the edge strip of the V-shaped frame 3, the side plate 12 cannot continue to rotate. At this time, the rotating component causes the clamping frame to reach its maximum inclination.

[0041] When the clamping rod 10 on the rear side of the clamping frame approaches the object through the power of the power component, the irregular object causes the clamping frame to rotate, and the first elastic member 14 provides resistance to the rotation of the bent plate 13. When the four clamping rods 10 all contact the object using the rotating sleeve 16, the object corresponds to the center of the center ring 101 at this time, and the clamping frame is locked using the locking component. After the moving frame 2 brings the object into the three-dimensional braiding machine 1, it is prevented that the yarn cannot be evenly woven on the surface of the object due to the offset of the object.

[0042] Example 2:

[0043] The present invention also provides a three-dimensional braided integral molding method for aviation composite sandwich structure blades, referring to Figures 1 to 5 As shown, the method uses the above-mentioned aviation composite material sandwich structure blade three-dimensional braiding integrated molding device, including the following steps:

[0044] S1. Place the object at the center of the rear side of the clamping component. The power component moves the pushing component through the push rod 4 and the V-shaped frame 3. The pushing component pushes the clamping component close to the object to complete the clamping of the object, so that the object corresponds to the center of the three-dimensional braiding machine 1; S2. Push the movable frame 2 to move backward. The moving movable frame 2 uses the clamping component to bring the object close to the three-dimensional braiding machine 1 until the clamping component moves backward at the center of the three-dimensional braiding machine 1. The three-dimensional braiding machine 1 weaves the braided material on the surface of the moving object; S3. A centering component is also installed on the rear side of the three-dimensional braiding machine 1. When the object carrying the braided material moves to the center of the centering component on the rear side, the clamping component on the front side of the three-dimensional braiding machine 1 releases the object, and the centering component on the rear side clamps the object carrying the braided material and pulls the object carrying the braided material out of the center of the three-dimensional braiding machine 1 to complete the three-dimensional braiding integrated molding process of the object.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
