[0002] In the aerospace field, by filling porous honeycomb structures, honeycomb materials are made to have heat-resistant and ablation-resistant properties to meet the needs of various aerospace products.

[0003] Currently, the injection of honeycomb cavity structures is carried out by manual hand-held injection gun for single-hole injection. The disadvantage of this method is that it requires a lot of manual labor for the injection of tens of thousands of honeycomb holes on large-sized honeycomb materials, and the degree of automation is low. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems. This utility model provides a feeding and filling device for honeycomb cavities to solve the problem that the existing filling method for honeycomb cavity structures requires a lot of manual labor and has a low degree of automation for filling a large number of honeycomb holes in large-size honeycomb materials.

[0006] The mixing drum 12 in the mixing assembly 1 is used to put in the material to be injected, and the material is mixed and dispersed by the internal mixing structure so that the material is discharged in a snowflake shape. The bottom of the mixing drum 12 is provided with at least two linear openings, and each linear opening is connected to the discharge mechanism at the corresponding position in the linear discharge assembly 2 so that the material is discharged to the linear discharge assembly 2 in turn through each linear opening.

[0007] The bottom end of each discharge mechanism in the linear discharge assembly 2 is connected to the corresponding group of feeding boxes 35 and weighing module 32 in the weighing and sorting assembly 3. The discharge port of the linear discharge assembly 2 is connected to the injection head 44 of the injection assembly 4. The material is discharged into the corresponding feeding box 35 in sequence through each discharge mechanism. The corresponding weighing module 32 measures the discharge weight of the feeding box 35. After the measured discharge weight reaches the set weight, the material in the feeding box 35 used for the current discharge is injected into the injection head 44 of the injection assembly 4 to realize the filling of a single honeycomb cell in the honeycomb structure.

[0008] The injection assembly 4 has an injection head 44 connected to a motor at its top. The motor drives the adjustment of its direction and angle to accommodate the injection of honeycomb cells in different shaped honeycomb structures. The injection head 44 is equipped with a six-lobed expansion mechanism 5. The expansion of the six-lobed structure at the end of the six-lobed expansion mechanism 5 is adapted to the inner contour of honeycomb cells of different sizes and shapes, so as to ensure that the six-lobed structure at the end of the six-lobed expansion mechanism 5 fills the inner holes of the honeycomb when the filler is compressed.

This allows the mixing drum 12 to communicate with the inner cavity of each hollow turntable 23 and the discharge port 24 through the linear opening and the gear opening, respectively. The drive shaft of the discharge servo motor 22 outside each hollow turntable 23 passes through the hollow turntable 23 and connects to the discharge gear 21 inside it. This drives the discharge gear 21 to rotate, and the rotation of the discharge gear 21 brings the material dispersed in the mixing drum 12 into the corresponding hollow turntable 23, and then injects it into the weighing and sorting assembly 3 through the discharge port 24.

The upper injection port of the injection head 44 is connected to the discharge cone 34 through a pipeline for feeding material into the injection head 44 in a single operation.

[0021] The injection assembly 4 is used to adjust the rotation direction and swing angle of the injection head 44 through the rotary motor assembly 41 and the swing motor assembly 42 so that the injection head 44 has the ability to swing in the 360° direction to adapt to honeycomb structures of various shapes; it is also used for the injection servo cylinder 43 to provide pressure to the injection head assembly 44 to compact the material put into the injection head 44.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0037] As explained in the background section above, the role of grouting in honeycomb cavity structures and the existing grouting method for honeycomb cavity structures, manual single-cell grouting, require a large amount of manual labor and has a low degree of automation for grouting tens of thousands of honeycomb cells on large-size honeycomb materials.

[0038] To address the aforementioned issues, this utility model provides a material filling device for honeycomb cavities, which enables automated filling of large-sized porous honeycomb ablation-resistant materials. Specifically, it can be used for the intelligent and automated filling of low-density ablation-resistant heat-resistant materials.

[0039] The present invention provides the following specific embodiments, which can be combined with each other. For the same or similar concepts or processes, they will not be described again in some embodiments.

[0040] Figure 1 This is a schematic diagram of the overall structure of a feeding and filling device for a honeycomb cavity provided in an embodiment of the present invention. Figure 2 for Figure 1 The illustrated embodiment provides a schematic diagram of the stirring assembly in a batching and filling device for honeycomb cavities. Figure 3 for Figure 1The illustrated embodiment provides a schematic diagram of the linear discharge assembly in a feeding and filling device for honeycomb cavities. Figure 4 for Figure 1 The illustrated embodiment provides a schematic diagram of the weighing and sorting component in a batching and filling device for honeycomb cavities. Figure 5 for Figure 1 The illustrated embodiment provides a schematic diagram of the filling assembly in a filling device for honeycomb cavities.

[0041] like Figures 1 to 5 As shown, the overall structure of the feeding and filling device for honeycomb cavities provided in this embodiment of the utility model includes four parts: a stirring assembly 1, a linear discharge assembly 2, a weighing and sorting assembly 3, and a filling assembly 4.

[0042] like Figures 1 to 4 As shown, the functions of each component and the cooperation relationships between them in this embodiment of the present invention are as follows:

[0043] like Figures 1 to 3 As shown, the mixing drum 12 in the mixing assembly 1 is used to put in the material to be injected, and the material is mixed and dispersed by the internal mixing structure so that the material is discharged in a snowflake shape. The bottom of the mixing drum 12 is provided with at least two linear openings, and each linear opening is connected to the discharge mechanism at the corresponding position in the linear discharge assembly 2 so that the material is discharged to the linear discharge assembly 2 in turn through each linear opening.

[0044] like Figure 3 and Figure 4 As shown, the bottom end of each discharge mechanism in the linear discharge assembly 2 is connected to the corresponding group of feeding boxes 35 and weighing modules 32 in the weighing and sorting assembly 3. The discharge port of the linear discharge assembly 2 is connected to the injection head 44 of the injection assembly 4, so that each discharge mechanism sequentially discharges material into the corresponding feeding box 35, and the corresponding weighing module 32 measures the discharge weight of the feeding box 35. After the measured discharge weight reaches the set weight, the material in the feeding box 35 used for the current discharge is injected into the injection head 44 of the injection assembly 4 to realize the filling of a single honeycomb cell in the honeycomb structure.

[0045] like Figure 5 As shown, the top of the injection head 44 in the injection assembly 4 is connected to a motor, which drives the adjustment of its direction and angle to adapt to the injection of honeycomb holes in different shaped honeycomb structures; the injection head 44 is provided with a six-lobed expansion mechanism 5, which expands through the six-lobed structure at the end of the six-lobed expansion mechanism 5 to adapt to the inner contour of honeycomb holes of different sizes and shapes, so as to ensure that the six-lobed structure at the end of the six-lobed expansion mechanism 5 expands to fill the inner hole of the honeycomb when the filler is pressed.

[0046] The feeding and filling device for honeycomb cavities provided in this embodiment of the utility model is required to achieve the following functions:

[0047] 1) Ensure that the material used for grouting fills each irregular honeycomb cell as required;

[0048] 2) The mixing component 1 of the batching and pouring device needs to mix and break the material into snowflake-like shapes to facilitate uniform pouring of the material;

[0049] 3) It is required to coordinate and control the speed of the discharge gear in the linear discharge assembly 2 and the weight measured by the weighing module 32 to ensure that the discharge amount is uniform and controllable each time;

[0050] 4) The injection assembly 4 is required to be equipped with a six-lobed expansion mechanism, which can adaptively expand each irregularly shaped honeycomb single hole.

[0051] In conjunction with the above-mentioned functions to be achieved by the feeding and filling device for honeycomb cavities provided in this embodiment of the present invention, the specific structure and working method of each component in the feeding and filling device are described in detail below:

[0052] (a) Agitator assembly;

[0053] The function of the mixing component 1 is to mix and disperse the material during discharge, so that the material is discharged in a snowflake-like shape, in order to ensure the smoothness of subsequent feeding and pouring.

[0054] Reference Figure 1 and 2 As shown, the mixing assembly 1 includes: a feeding port 11, a mixing drum 12, a mixing frequency converter motor 13, and an installation platform; the mixing drum 12 is configured as a cylindrical structure and is installed horizontally on the installation platform. The top of the mixing drum 12 is provided with a feeding port 11. The mixing frequency converter motor 13 is fixedly installed on the installation platform, and its mixing paddle is placed in the mixing drum 12 to mix and disperse the material fed into the mixing drum 12 through the feeding port 11, so that the material is discharged in a snowflake-like manner to ensure the smoothness of subsequent feeding and pouring.

[0055] In the mixing assembly 1, at least two linear openings are provided at intervals at the bottom of the mixing drum 12. The bottom of the mixing drum 12 passes through the opening on the mounting platform and is located above the discharge top plate of the linear discharge assembly 2. The mixing drum 12 is connected to each discharge mechanism of the linear discharge assembly 2 through each linear opening. Under the cooperation of each discharge mechanism in the linear discharge assembly 2, the material dispersed in the mixing drum 12 is discharged into each discharge mechanism in sequence through each linear opening.

[0056] In one implementation, a 60L mixing assembly 1 is designed based on the amount of material to be mixed at one time. The variable frequency motor 13 of the mixing assembly 1 can adjust the rotation speed of the mixing paddle, and can break the material into different degrees of looseness according to the process requirements.

[0057] (ii) Linear discharge assembly;

[0058] The function of the linear discharge component 2 is to ensure that the discharge amount is uniform and controllable each time. By discharging material into a single cell of the honeycomb structure in a single discharge, the quality of the injected material in a single cell can be controlled by controlling the discharge amount in a single discharge.

[0059] Reference Figures 1 to 3 As shown, the linear discharge assembly 2 includes a discharge top plate and multiple sets of discharge mechanisms, the same number as the linear openings at the bottom of the mixing drum 12. Each set of discharge mechanisms includes a discharge gear 21, a discharge servo motor 22, a hollow turntable 23, and a discharge port 24.

[0060] Figure 6 for Figure 3 A cross-sectional view along the plane of the hollow turntable of the linear discharge assembly provided in the illustrated embodiment, referring to... Figure 3 and Figure 6 As shown in the embodiment of this utility model, the discharge top plate is provided with multiple gear ports that are the same number and position as the linear openings at the bottom of the stirring drum 12. Each hollow turntable 23 is provided with one discharge gear 21. The bottom of each hollow turntable 23 is connected to a discharge port 24. Each hollow turntable 23 is vertically arranged at the bottom of the discharge top plate, so that the top of the discharge gear 21 provided inside each hollow turntable 23 passes through the gear port at the corresponding position on the discharge top plate and the linear opening at the corresponding position at the bottom of the stirring drum 12. This allows the stirring drum 12 to communicate with the inner cavity of each hollow turntable 23 and the discharge port 24 through the linear opening and the gear port, respectively. The drive shaft of the discharge servo motor 22 provided outside each hollow turntable 23 passes through the hollow turntable 23 and is connected to the discharge gear 21 inside it. This drives the discharge gear 21 to rotate. The rotation of the discharge gear 21 brings the material dispersed in the stirring drum 12 into the corresponding hollow turntable 23 and injects it into the weighing and sorting component 3 through the discharge port 24.

[0061] In specific implementation, each discharge servo motor 22 in the linear discharge assembly 2 is connected to the controller to control each discharge servo motor 22 to work in turn in turn, so as to drive the discharge gear 21 in the corresponding hollow turntable 23 to rotate in a time-sharing manner, thereby controlling each group of discharge mechanisms in the linear discharge assembly 2 to work in a time-sharing manner. By cooperating with the weighing module 32 in the weighing and sorting assembly 3, the single discharge amount of each group of discharge mechanisms is controlled, and the discharge speed is controlled by controlling the rotation speed of the discharge gear 21.

[0062] In one embodiment, the single discharge volume of the linear discharge component 2 is controlled, for example, to be 4-5g. The discharge speed is controlled by the rotational speed of the discharge servo motor 22, which operates at 90% high speed in the early stage and at 10% low speed thereafter, ensuring that the discharge error is within a controllable range. The gear ports on the discharge top plate of the linear discharge component 2 directly connect to the linear openings of the stirring drum 12 in the stirring component 1, resulting in a compact overall structure. Furthermore, by cooperating with the weighing module 32 in the weighing and sorting component 3, the rotational speed of the discharge servo motor 22 can be controlled to ensure that the discharge error is minimized.

[0063] (III) Weighing and sorting components;

[0064] The function of the weighing and sorting component 3 is: mainly used for material sorting and weighing, so as to achieve precise control of the material filling weight.

[0065] Reference Figure 1 , Figure 3 and Figure 5 As shown, the weighing and sorting assembly 3 includes: a weighing base plate, a precision pusher cylinder 31, shock absorbers 33, a discharge cone 34, and multiple sets of feeding boxes 35 and weighing modules 32, which are the same number and position as the discharge port 24. Four shock absorbers 33 are fixedly installed at the four corners of the upper surface of the weighing base plate, and are fixedly installed to the lower surface of the discharge top plate to prevent vibration of the mixing assembly 1 from affecting the weighing data.

[0066] Each feeding box 35 has a corresponding discharge port 24 connected to its top, and a weighing module 32 is set below it. The feeding box 35 and the weighing module 32 are separated by a partition plate. The weighing structure formed by multiple sets of feeding boxes 35 and weighing modules 32 is arranged sequentially on one side of the weighing bottom plate. The bottom of the weighing bottom plate is fixedly installed with a discharge cone 34, which is located directly below each set of weighing modules 32. The weighing bottom plate has an opening at the bottom of each weighing module 32. A pusher precision cylinder 31 is set inside each weighing module 32 and is connected to the partition plate of each set of weighing structures. The pusher precision cylinder 31 pulls the partition plate to push the material in the feeding box 35 into the discharge cone 34. The material is fed into a single honeycomb cell of the honeycomb structure by the cooperation of a set of discharge mechanism in the linear discharge assembly 2 with a set of feeding boxes 35 and weighing modules 32.

[0067] like Figure 3 and Figure 4 As shown, in one embodiment, the linear discharge assembly 2 has 4 sets of discharge mechanisms, and the weighing and sorting assembly 3 is provided with 4 sets of feeding boxes 35 and 4 sets of high-precision weighing modules 32.

[0068] The working principle of the weighing and sorting component 3 is as follows: during the discharge process performed by the single discharge mechanism of the linear discharge component 2, when the single discharge weight reaches the set weight, the corresponding isolation plate is pulled by the retraction of the pusher precision cylinder 31 to push the material in the feeding box 35 into the discharge cone 34 through the weighing module 32. After the pusher is completed, the pusher precision cylinder 31 is reset.

[0069] It should be noted that in this embodiment of the utility model, material is discharged through a single discharge mechanism. After the weighing module 32 determines that the material discharge amount has reached the set weight, the material discharge operation of the discharge mechanism is stopped. At the same time, the material is discharged through the weighing and sorting component 3, and the next discharge mechanism continues to discharge. Thus, each discharge mechanism discharges material in turn, and the feeding is completed through the corresponding feeding box 35 and the weighing module 32.

[0070] (iv) Injection assembly

[0071] The function of the injection component 4 is to inject the material that has been dispensed and distributed by the weighing and sorting component 3 into a single designated honeycomb cell in the honeycomb mechanism, and to compact the material by setting a pressure.

[0072] Reference Figure 1 and Figure 6 As shown, the injection assembly 4 includes: an injection housing 45, a rotary motor assembly 41, a swing motor assembly 42, an injection servo cylinder 43, and an injection head 44. The rotary motor assembly 41 extends from the top of the injection housing 45 through the housing and connects to the injection head 44, such that the injection head 44 is located at the bottom of the injection housing 45. The injection housing 45 contains the swing motor assembly 42 and the injection servo cylinder 43, both connected to the injection head 44. The upper injection port of the injection head 44 is connected to a discharge cone 34 via a pipeline for feeding material into the injection head 44 in a single operation.

[0073] The injection assembly 4, on the one hand, adjusts the rotation direction and swing angle of the injection head 44 through the rotary motor assembly 41 and the swing motor assembly 42 connected to the injection head 44. Through motion control in two degrees of freedom, the injection head 44 can swing in all 360° directions to adapt to various honeycomb structures, such as filling the honeycomb cells of arc-shaped honeycomb products. On the other hand, the injection servo cylinder 43 provides sufficient pressure to the injection head assembly 44 to compact the material injected into the injection head 44. In specific implementation, the pressure can be adjusted by controlling the rotation speed of the discharge servo cylinder 43 to complete the injection operation according to the specified pressure requirements.

[0074] Furthermore, the injection assembly 4 provided in this embodiment of the present invention has a six-lobed expansion mechanism 5 inside the injection head 44, such as... Figure 7 As shown, Figure 6The illustrated embodiment provides a schematic diagram of the six-lobed expansion mechanism in the injection assembly. The six-lobed expansion mechanism 5 includes: a hollow main shaft 54, a telescopic cylinder 51, a bearing flange 52, and a six-lobed expansion pin 53.

[0075] like Figure 7 As shown, the telescopic cylinder 51 is fixedly installed on the upper part of the main shaft 54, and the bearing flange 52 is sleeved in the middle of the main shaft 54 ​​and connected to the drive end of the telescopic cylinder 51. It is used to drive the bearing flange 52 to move axially along the main shaft 54 ​​through the telescopic cylinder 51. The bottom of the main shaft 54 ​​is connected to the six-lobed expansion pestle 53, and the shaft body connecting the six-lobed expansion pestle 53 and the main shaft 54 ​​is a hollow structure.

[0076] like Figure 7 As shown, six sets of nuts are arranged circumferentially on the outside of the bearing flange 52. Six sets of steel wires are arranged in the shaft cavity of the main shaft 54 ​​and the six-lobed expander 53. One end of each set of steel wires is fixedly connected to one set of nuts on the outside of the bearing flange 52, and the other end is connected to one lobe at the end of the six-lobed expander 53. Springs are installed in the six lobes at the end of the six-lobed expander 53. The six lobes are pulled back and retracted by the steel wires connected to the bearing flange 52 through the contraction of the telescopic cylinder 51. The six lobes at the end are opened by the springs inside them through the extension of the telescopic cylinder 51.

[0077] In one embodiment of this utility model, the six-lobed expanding pestle 53 is an expansion and pressing structure specifically designed for hexagonal honeycombs. Its expansion and contraction range is adjustable and controllable, for example, within a diameter of 12-16 mm. The outer surface of the front pressing mechanism is made of a flexible material to ensure that the inner wall of the honeycomb cells is not damaged during pressing. The six-lobed expanding pestle 53 has an internal mechanical elastic structure to ensure smooth opening and contraction. The main shaft 54 ​​is made of high-strength alloy to ensure it can withstand the maximum pressing pressure. When the six-lobed expanding pestle 53 contracts, the telescopic cylinder 51 drives the steel wire connected to the bearing flange 52 to pull the six lobes back and retract. When opening, the telescopic cylinder 51 extends, and the six lobes are internally supported by springs. When encountering irregularly shaped holes, due to the spring force, the six lobes can adapt to the inner contour of the honeycomb holes, ensuring that the front end of the six-lobed expanding pestle 53 expands and fills the inner holes of the honeycomb when the filler is pressed.

[0078] The material filling device for honeycomb cavities provided in this embodiment of the invention achieves the filling operation of a single honeycomb cell in the honeycomb structure through the coordinated operation of the stirring assembly 1, the linear discharge assembly 2, the weighing and sorting assembly 3, and the filling assembly 4. The feeding and filling device provided in this embodiment of the utility model has the following effects: On the one hand, the stirring component 1 stirs and disperses the material, making it appear as snowflakes, to ensure smooth subsequent feeding and filling, and to prepare for precise feeding; on the other hand, the alternating feeding of each group of feeding mechanisms in the linear feeding component 2, and the weighing coordination of the weighing and sorting component 3, ensure that the amount of material fed each time is uniform and controllable. The material is then injected into each individual honeycomb cell of the honeycomb structure in sequence with a single controllable amount of material fed, thus achieving uniform and controllable material injection into each honeycomb cell, that is, achieving precise feeding into each honeycomb cell; furthermore, during the feeding process implemented by the feeding component 4, not only can the rotation direction and swing angle of the feeding head 44 be adjusted to suit various types of honeycomb structures; furthermore, through the six-lobed expansion mechanism 5 set inside the feeding head 44, it can adapt to the inner contour of the honeycomb cell, ensuring that the front end of the six-lobed expansion pest 53 expands and fills the inner hole of the honeycomb when the filler is compressed.

Any person skilled in the art to which this utility model pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this utility model, but the patent protection scope of this utility model shall still be determined by the scope defined in the appended claims.
