DETAILED DESCRIPTION

[0039] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered by the following.

[0040] Reference Figure 5 , Figures 8-10 , Figures 14-15 The preferred embodiment of the present application provides a honeycomb structure ring processing method, comprising the following steps:

[0041] Honeycomb structure sheet 1 fixation: the honeycomb structure sheet 1 surrounding the honeycomb structure ring to be processed is clamped and fixed to the positioning fixture 3 provided in the vibration filling device 2, and the core cell opening 102 of the core cell 101 of the honeycomb structure sheet 1 is upward.

[0042] Soft material filling: the core cell 101 is filled with dense and compact soft material by means of vibration filling device 2 combined with manual operation.

[0043] Excess removal and size guarantee: turning is used to process the inner ring surface of the honeycomb structure ring combined into a ring shape to remove burrs and guarantee the size accuracy.

[0044] Filling material removal: the soft material filled in the processed honeycomb structure ring is removed.

[0045] The processing method of the application, the positioning and fixing device 3 is used for clamping and fixing the honeycomb structure sheet 1 to be filled, so as to avoid the position loosening of the honeycomb structure sheet 1 due to vibration when the vibrating filling device 2 vibrates, which causes the originally upward core cell port 102 on the core cell 101 to tilt to one side, and further affects the filling of the soft material on the core cell 101, which causes the long filling time of the soft material, the core cell 101 is not easy to be filled after the filling is completed, and further causes the long and large operation difficulty of the subsequent paste supplementing, and the poor paste supplementing effect; in the processing method of the application, the core cell 101 is filled with the soft material, and the core cell 101 is filled with the dense and compact soft material after the filling is completed, and further the rigidity of the honeycomb structure sheet 1 is improved, the honeycomb structure ring is damaged due to insufficient rigidity in the processing process, and the honeycomb structure ring is processed by turning due to the characteristics of sufficient rigidity and easy turning of the material itself, and further the processing efficiency of the inner diameter of the honeycomb structure ring is greatly improved, and the processing efficiency is about 5 times of that of the electric spark grinding and the grinding wheel grinding, and the burr generated in the processing process can be effectively reduced, and the subsequent workload is reduced.

[0046] Optionally, as shown in Figure 5 , the positioning and fixing device 3 is used for clamping and fixing the honeycomb structure sheet 1 with different number, shape and size, so that the honeycomb structure sheet 1 with any shape within a certain diameter size range can be clamped and fixed by the positioning and fixing device 3 of the application, and a plurality of honeycomb structure sheets 1 can be clamped and fixed at the same time, so that the application range of the positioning and fixing device 3 is greatly improved, and the processing cost is reduced.

[0047] In this optional scheme, as shown in Figure 5 , the positioning and fixing device 3 includes a mounting bottom plate 31 used for detachable fixing with the vibrating filling device 2, two blocks of fastening unit walls 32 arranged in opposite intervals, and an elastic connecting piece 33 used for elastic connection. The first block of fastening unit walls 32 is vertically fixed and arranged on the mounting bottom plate 31, and the second block of fastening unit walls 32 is vertically and slidably arranged on the mounting bottom plate 31. The two blocks of fastening unit walls 32 are used for adaptive deformation according to the shape of the clamped honeycomb structure sheet 1 to relatively stably hold the honeycomb structure sheet 1. The elastic connecting piece 33 is connected between the two blocks of fastening unit walls 32, and is used for relatively tensioning the two blocks of fastening unit walls 32. During clamping, the honeycomb structure sheet 1 is placed between the two blocks of fastening unit walls 32 through the movement of the slidingly arranged fastening unit wall 32, and then the honeycomb structure sheet 1 is held between the two blocks of fastening unit walls 32 through the honeycomb mounting ear 11 on the honeycomb structure sheet 1 by the adaptive deformation of the two blocks of fastening unit walls 32 according to the shape of the honeycomb structure sheet 1, and finally the two blocks of fastening unit walls 32 are relatively tensioned by the elastic connecting piece 33, so that the honeycomb structure sheet 1 is stably fixed between the two blocks of fastening unit walls 32, and the rapid filling of the core cell 101 of the honeycomb structure sheet 1 is realized.

[0048] Preferably, guide rails are arranged on the mounting base plate 31, and the bottom of the slidingly arranged fastening unit wall 32 is matched with the guide rails through a sliding groove to limit and guide the sliding of the fastening unit wall 32, and the fastening unit wall 32 can be used to clamp and fasten the honeycomb structure piece 1 of different sizes.

[0049] In this optional solution, as shown in Figure 5 The fastening unit wall 32 includes a support plate 321 vertically arranged on the mounting base plate 31, a plurality of fastening unit rods 322 vertically penetrating the support plate 321 and sliding, and an elastic skin 323 for limiting the fastening unit rods 322. The elastic skin 323 is fixed to the outer vertical surface of the support plate 321 and elastically abuts against the outer extending end of the fastening unit rod 322 to press the fastening unit rod 322 towards the inner vertical surface of the support plate 321. In operation, only the slidingly arranged support plate 321 is required to be moved away from the fixedly arranged support plate 321, then the honeycomb structure piece 1 is placed in the appropriate position between the two fastening unit walls 32, and then the slidingly arranged support plate 321 is slowly released. The positioning and fixing device can automatically complete the fastening under the action of the elastic connecting piece 33 and the elastic skin 323, and the fastening unit wall 32 can self-adapt to the honeycomb structure piece 1 of different shapes, sizes and quantities, as shown in Figure 6 .

[0050] In the specific embodiment of this optional solution, as shown in Figure 5 The fastening unit rod 322 includes an outer extending section and an inner pressing section arranged and connected in sequence along the axial direction, the outer extending section is used to abut against the elastic skin 323, the inner pressing section is used to abut against the honeycomb structure piece 1, and the outer diameter of the outer extending section is larger than that of the inner pressing section. The stepped hole is arranged on the support plate 321 for the fastening unit rod 322 to vertically penetrate and adapt to the outer diameter of the outer extending section and the inner pressing section, so as to limit the fastening unit rod 322 to be pressed out of the support plate 321 under the action of the elastic skin 323.

[0051] Optionally, in the present application, the soft material is a soft material similar to graphite, such as Ni-Al powder, etc., to increase the rigidity of the honeycomb structure piece 1 and strengthen the strength of the wall of the honeycomb structure piece 1, so as to complete the stock removal machining and ensure the size by using the turning machining method which has higher processing efficiency and relatively lower threshold; and since the core grid 101 is a semi-closed structure, and the depth to width ratio of the core grid 101 of the honeycomb structure piece 1 before machining can generally reach about 5 / 1, as shown in Figures 7-8 Due to the relative difficulty of direct filling of soft material, in the present application, the dry filling and wet filling are combined to fill the soft material, so that the step of "soft material filling" in the present application specifically includes the following steps:

[0052] Dry filling: automatically fill the honeycomb structure sheet 1 with dry soft material in the core cells 101 by the vibration filling device 2. Specifically, the dry filling is a vibration filling method, that is, the honeycomb structure sheet 1 to be filled with soft material is clamped and fixed in the positioning and fixing device 3 of the vibration filling device 2, the core cell opening 102 of the honeycomb structure sheet 1 is upward, and an appropriate amount of soft material powder is put into the container of the vibration filling device 2, and the powder must be higher than the honeycomb structure sheet 1 by a certain depth; then the container is connected to the vibration device at the bottom for vibration, so that the soft material is fully filled into the core cells 101, and the vibration amplitude, frequency and time are determined according to the specific conditions of the honeycomb structure sheet 1 and the soft material powder. The vibration process needs to seal the container to avoid dust, as shown in Figure 9 .

[0053] Wet filling: fill the core cells 101 with compact and wet soft material by the combination of vibration filling device 2 and manual operation. After the dry filling is completed, the soft material powder will fill the core cells 101 of the honeycomb structure sheet 1, but at this time the soft material in the core cells 101 is relatively soft, and the rigid strengthening effect on the honeycomb structure sheet 1 is limited, so wet filling is still needed to fill the core cells 101 with compact and wet soft material, so as to further improve the rigidity of the honeycomb structure sheet 1.

[0054] Drying treatment: dry the wet soft material to enhance the rigidity of the whole honeycomb structure sheet 1. Specifically, after the soft material is filled, it needs to be dried or baked, and the strength of the soft material will increase with the decrease of water content, but if the baking is too much, the strength will decrease, which is not convenient for subsequent processing. The drying or baking temperature and time are determined according to the actual situation.

[0055] In this optional solution, the step of "wet filling" specifically includes the following steps:

[0056] Wetting: wet and vibrate the honeycomb structure sheet 1 by the vibration filling device 2, so as to wet and compact the soft material filled in the core cells 101. Specifically, first, the dry soft material powder filled in the container is treated, that is, the excess soft material powder in the container is removed, and then the container is sprayed with water mist while vibrating, so as to soak the soft material powder in the core cells 101, as shown in Figure 10 , and the filling state of the soft material in the core cells 101 before soaking is as shown in Figure 11 , and the filling state of the soft material in the core cells 101 after soaking is as shown in Figure 12 .

[0057] Paste supplementing: supplement and compact the paste of the soft material in the core cells 101. Specifically, with the soaking and vibration of the powder, the soft material in the core cells 101 will gradually compact, but the filling rate of the soft material in the core cells 101 will gradually decrease, as shown in Figures 11-12As shown, therefore, it is necessary to replenish the soft material, and the paste prepared by mixing the soft material with water is used to fill and compact the hollow section in the core cell 101, so as to further improve the compactness of the soft material in the core cell 101 and prepare for further improvement of the stiffness of the honeycomb structure sheet 1.

[0058] Alternatively, if the paste of soft material is directly used for filling, since the core cell 101 of the honeycomb structure sheet 1 is a semi-closed structure and has a large depth-width ratio, the filling will form an airtight effect, and the bottom of the core cell 101 cannot be filled, as shown. Figure 13

[0059] Alternatively, the step of "residual removal and size guarantee" specifically includes the following steps:

[0060] Rough machining: rough turning of the inner ring surface of the combined honeycomb structure ring to remove the excess amount.

[0061] Finish machining: finish machining of the inner ring surface of the rough-turned honeycomb structure ring to remove burrs and guarantee the machining size accuracy.

[0062] Specifically, compared with electric spark grinding and grinding wheel grinding machining, the material in the inner diameter of the honeycomb structure ring needs to be ground layer by layer into powder, while in the present application, the honeycomb structure ring filled with soft material has improved stiffness, and can be machined by turning. Since the honeycomb structure ring is relatively easy to cut, it can be machined with a large cutting depth. Therefore, during machining, only one rough machining is needed to remove the excess amount, and one finish machining is needed to remove burrs and guarantee the size, which is high in machining efficiency and can achieve about 5 times of electric spark grinding and grinding wheel grinding. Since the core cell 101 is filled with soft material, burrs are not easy to occur on the machining surface, and only a small amount of burrs will occur at the edge of the cut-out part, which can be easily cleaned later.

[0063] Preferably, as shown in Figure 14 In the step of "finish machining", the axial bidirectional opposite cutting machining method is adopted, i.e., cutting from the axial upper side and lower side respectively, and then cutting out along the circular arc after the machining tracks are connected at the middle position. In the preferred embodiment, in order to further reduce the generation of burrs, the finish machining adopts the axial bidirectional opposite cutting machining method, i.e., cutting from the axial upper side and lower side respectively, and then cutting out along the circular arc after the machining tracks are connected at the middle position. As shown in Figure 14 Therefore, the finish machining does not have a cut-out edge, i.e., no burrs are generated, and subsequent burr removal work is no longer needed, which greatly reduces the work intensity of the workers in the later stage and shortens the machining cycle.

[0064] Alternatively, as shown in Figure 15 ​As shown, the step of "filling material removal" specifically comprises the following steps:

[0065] Drying: drying the soft material filled in the honeycomb structure sheet 1.

[0066] Blowing: blowing the soft material out of the core cell 101 of the honeycomb structure sheet 1 by using compressed air.

[0067] Cleaning: cleaning the core cell 101 by using ultrasonic wave.

[0068] Specifically, since no other adhesive is used when filling the soft material, the soft material is relatively easy to remove. First, the filling material of the honeycomb structure sheet 1 needs to be fully dried, and then the soft material will become crisp after losing all the water. Then, most of the soft material can be removed by blowing the core cell 101 by using compressed air. If the core cell opening 102 of the honeycomb structure sheet 1 is fixed downward by the positioning and fixing device 3 and vibrated by the vibrating filling device 2 before blowing, as shown in Figure 15 , the effect of soft material removal will be better. After most of the soft material is removed, the core cell opening 102 of the honeycomb structure sheet 1 is placed downward, and the soft material can be completely removed by ultrasonic cleaning. The material removal operation is simple, time-saving and labor-saving.

[0069] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
