Description

Technical Field

[0001] The present invention belongs to the technical field of functional honeycomb manufacturing, and relates to a honeycomb embedded diaphragm implantation tooling and method. Background Art

[0002] Based on the resonance absorption structure of the embedded honeycomb, it exhibits good sound absorption ability based on the Helmholtz resonance mechanism, can achieve more than 90% sound absorption ability at specific frequencies, and inherits the characteristics of the honeycomb such as light weight, high strength, and excellent dielectric properties, and has the ability of structural-functional integration. The stable and complete implantation technology of its micro-perforated diaphragm is the key to ensuring the good performance of the sound absorption structure of this structure. By implanting the diaphragm, the honeycomb cavity is divided into multiple cavities with different thicknesses. The depth of the diaphragm implantation, that is, the size of the cavity volume, determines the sound insulation ability and frequency of the honeycomb. At present, for the implantation tooling, whether it is the automatic implantation equipment involved in the invention CN108931933 or the ordinary implantation equipment involved in CN107116848, the implantation process is realized in the form of mechanical pressing, and the honeycomb needs to be flipped when adjusting the height.

[0003] Currently, the main implantation technology of the diaphragm is to lay the diaphragm on the surface of the honeycomb and then implant it in the in-situ filling mode of mechanical pressing. Whether it is the automatic or manual implantation mode, it will cause the deformation of the diaphragm due to mechanical pressing, and once the diaphragm is implanted, its height can only be adjusted downward and cannot be adjusted upward. In addition, relying on the honeycomb wall to cut the diaphragm during the pressing process is also likely to cause the deformation of the implanted diaphragm. Summary of the Invention

[0004] Object of the Invention

[0005] The present invention provides a high-precision implantation equipment tooling and method for honeycomb embedded diaphragms, which improves the implantation accuracy and operation efficiency of the diaphragms in the sound absorption honeycomb structure.

[0006] Technical Solution

[0007] A high-precision implantation equipment tooling for honeycomb embedded diaphragms includes:

[0008] Cylinder 1, vacuum generator 2, controller and solenoid valve control mechanism 3, stamping rod 4, guide post 5, and adsorbable punch 7;

[0009] The lower end of cylinder 1 is fixed on the upper surface of the double-hole plate-like structure, the controller and solenoid valve control mechanism 3 are fixed on the lower surface of the double-hole plate-like structure, the guide post 5 passes through the holes of the double-hole plate-like structure, and both ends are fixed on the external iron frame of the structure. The controller and solenoid valve control mechanism 3 can move up and down relative to the guide post 5 through the double-hole plate-like structure; the vacuum generator 2 is connected to the controller and solenoid valve control mechanism 3; the upper end of the stamping rod 4 is fixed to the vacuum generator 2, and the lower end of the stamping rod 4 is fixed with an adsorbable punch 7.

[0010] It also includes: a tool mechanism 6, which is a hexagonal structure composed of 6 blades, sleeved on the lower part of the stamping rod 4, and can be adsorbed above the punch 7.

[0011] The size of the hexagonal tool is adjusted according to the size of the implanted honeycomb cell.

[0012] The adsorbable punch 7 is fixed on the stamping rod 4 in a bonding manner.

[0013] Both ends of the guide post 5 are fixed on the external iron frame of the structure through bolts and gaskets.

[0014] The vacuum generator 2 is connected to the controller and the solenoid valve control mechanism 3 through angle iron sheets.

[0015] A high-precision implantation method for a honeycomb-embedded diaphragm includes:

[0016] Step 1: After the honeycomb is fixed and the hole is positioned on the implantation device, the diaphragm is fed by the mechanism, and the implantation operation starts.

[0017] Step 2: Mechanism debugging, the cylinder 1 acts, controlling the entire stamping rod 4 to move downward.

[0018] Step 3: When the adsorbable punch 7 is about to contact the diaphragm, the vacuum generator 2 acts. When the adsorbable punch 7 is in full contact with the diaphragm, the diaphragm can be stably adsorbed on the adsorbable punch 7, and at this time the tool mechanism 6 is stationary.

[0019] Step 4: Then the cylinder 1 continues to act to push the stamping rod 4 downward, and the tool mechanism 6 acts to cut the diaphragm, with a size approximately similar to that of the honeycomb cell.

[0020] Step 5: The stamping rod 4 continues to move downward, pressing the cut diaphragm into the honeycomb cell.

[0021] Step 6: Perform diaphragm implantation depth regulation, and adjust the implantation height according to the visual recognition mechanism of the implantation device.

[0022] Step 7: Confirm that the implantation is completed, record the implantation depth, turn off the vacuum generator 2, and the adsorbable punch 7 is separated from the diaphragm to complete the implantation operation.

[0023] In Step 6, the one-stroke time of the device is controlled by the controller and the solenoid valve control mechanism (3).

[0024] Beneficial effects

[0025] The present invention relates to a tooling for high-precision implantation of an embedded diaphragm, which can achieve high-precision implantation of the fixed height of the embedded diaphragm in the honeycomb in an adsorption manner through an adsorbable punch, and can adjust the implantation height at any time.

[0026] The present invention also relates to a method for high-precision implantation of an embedded diaphragm, which includes a method combining vacuum adsorption and tool cutting to avoid diaphragm damage during direct stamping and improve the yield rate of diaphragm implantation. Description of the Drawings

[0027] Figure 1 It is a structural schematic diagram of the equipment and tooling of the present invention.

[0028] Figure 2 It is a flowchart of the method of the present invention. Detailed Embodiments

[0029] The present invention relates to an equipment and tooling for high-precision implantation of a honeycomb embedded diaphragm, as Figure 1 shown, mainly including 1 - cylinder; 2 - vacuum generator; 3 - controller and solenoid valve control mechanism; 4 - stamping rod; 5 - guide post; 6 - tool mechanism; 7 - adsorbable punch. The cylinder 1 is fixed on a double-hole plate-like structure by 4 bolts. At the same time, the controller and solenoid valve control mechanism 3 is adjacent to the cylinder 1 up and down and is also fixed on the double-hole plate-like structure by bolts, and is integrally combined with two guide posts 2, so that the cylinder 1 and the controller and solenoid valve control mechanism 3 can move up and down on the guide post 5. Each guide post 5 is fixed on the external iron frame of the structure by bolts and gaskets up and down. The vacuum generator 2 is connected to the controller and solenoid valve control mechanism 3 through an angle iron sheet and is fixed by bolts. The stamping rod 4 is fixed to the vacuum generator 2 by welding. The adsorbable punch 7 is the bottom structure of the stamping rod 4 and is directly fixed by adhesive bonding. The tool mechanism 6 is a hexagonal structure composed of 6 blades and is fixed to the lower end of the stamping rod 4 by a bolt in a socket form. The size of the hexagonal tool can be adjusted according to the size of the implanted honeycomb space to ensure cutting after adsorption and stamping.

[0030] This equipment and tooling can be used in combination with an automated diaphragm implantation machine tool. After the equipment is positioned, the adsorbable punch 7 starts to perform diaphragm adsorption and stamping operations, and at this time, the tool mechanism 6 is stationary. Then the ejector cylinder acts to push the stamping rod 4 downward. When the adsorbable punch 7 contacts the adhesive film, the vacuum generator acts to adsorb the diaphragm. At the same time, the tool mechanism 6 acts first to cut out a hexagonal diaphragm piece similar in size to the honeycomb cell from the diaphragm, and then the punch drives the diaphragm into the honeycomb hole. The one-stroke time can be precisely controlled by the controller and the two-position five-way pneumatic solenoid valve 3, and the pneumatic stroke accuracy can reach ±0.05 mm, meeting the honeycomb implantation depth accuracy of ±0.5 mm. Finally, the implantation depth is confirmed and adjusted according to the vision recognition structure of the automated diaphragm implantation machine tool. All cylinders are pressurized by an air compressor, and the control unit controls the movement of the adsorbable punch 7 and the tool mechanism 6 through pressure control and auxiliary components such as solenoid valves, pressure control valves, and reversing valves.

[0031] Among them, the cutting tool mechanism 6 can be selectively used. The use of the cutting tool mechanism 6 is because when the diaphragm is pressed into the honeycomb cavity, bending stress may be generated due to the bending and folding of the diaphragm during the pressing process. For diaphragms with lower density or thickness, this stress is small and hardly affects the diaphragm implantation process. However, for diaphragms with higher density or thickness, the existence of this stress will cause the diaphragm not to closely adhere to the honeycomb wall, resulting in diaphragm damage and implantation failure.

[0032] The key points of the device of the present invention are as follows:

[0033] (1) The present invention designs an adsorbable punch containing a vacuum generator to achieve the complete adsorption and embedding of the diaphragm, ensuring the integrity of the diaphragm in step 3;

[0034] (2) The present invention can, through the controller and the two-position five-way pneumatic solenoid valve 6, combined with the original vision device of the implantation mechanism, perform height adjustment according to the requirements of the implantation structure. Combining with the adsorbable punch (structure 7), it can achieve high-precision up and down adjustment of the embedded diaphragm, improving the adjustability of the design. The pneumatic stroke accuracy can reach ±0.05 mm, meeting the honeycomb implantation depth accuracy of ±0.5 mm;

[0035] (3) The present invention designs a cutting tool mechanism, the structure of which is a hexagonal structure composed of 6 blades, and its size can be adjusted according to the size of the implanted honeycomb space, ensuring the overall cutting and embedding of the diaphragm and avoiding pressing damage.

[0036] As Figure 2 shown, the specific use process of the present invention is as follows:

[0037] (1) After the honeycomb is fixed and the hole is positioned by the implantation device, the diaphragm is sent in by the mechanism to start the implantation operation;

[0038] (2) Mechanism debugging, the cylinder 1 acts to control the entire punching rod mechanism 5 to move downward;

[0039] (3) When the punch 7 is about to contact the diaphragm, the vacuum generator 2 acts. When the adsorbable punch 7 is in full contact with the diaphragm, the diaphragm can be stably adsorbed on the adsorbable punch 7, and at this time, the cutting tool mechanism 6 is stationary;

[0040] (4) Then the ejector rod cylinder 1 continues to act to push the punching rod 7 downward, and the cutting tool mechanism 6 acts to cut the diaphragm, with a size approximately the same as the honeycomb cell size;

[0041] (5) The punching rod mechanism 4 continues to move downward to press the cut diaphragm into the honeycomb cell;

[0042] (6) Adjust the depth of diaphragm implantation, and adjust the implantation height according to the visual recognition mechanism of the implantation device. The one-stroke time of the device can be precisely controlled by the controller and the five-port two-position pneumatic solenoid valve 3, and the pneumatic stroke accuracy can reach ±0.05 mm, meeting the honeycomb implantation depth accuracy of ±0.5 mm;

[0043] (7) Confirm the completion of implantation, record the implantation depth, turn off the vacuum generator 2, and separate the punch 7 from the diaphragm to complete the implantation operation.

[0044] The key points of the method of the present invention are as follows:

[0045] (1) Improve the operability of the sound-absorbing honeycomb embedded diaphragm implantation. In step 3, the up and down adjustment of the embedded diaphragm can be realized through the adsorbable punch, and at the same time, the vacuum adsorption ensures the integrity of the implanted diaphragm structure;

[0046] (2) Improve the diaphragm implantation accuracy. Precise control is achieved in step 6. The one-stroke time can be precisely controlled by the controller and the five-port two-position pneumatic solenoid valve 3, and the pneumatic stroke accuracy of the punch can reach ±0.05 mm;

[0047] (3) The tool mechanism in step 4 can cut six slits passing through the vertices on the hexagonal patch to achieve the purpose of eliminating stress, enabling the diaphragm to be closely attached to the inner wall, ensuring the integrity of the diaphragm embedding, and avoiding diaphragm damage during the stamping process.
