Description

Technical Field

[0001] This utility model relates to the field of honeycomb cell stacking and welding technology, and in particular to a honeycomb cell stacking positioning mechanism for a wind tunnel honeycomb module welding device. Background Technology

[0002] A honeycomb module is a precision engineering component that mimics the structure of a honeycomb in nature. It consists of countless thin-walled small channels (called "cells") with cross-sections of regular hexagons or other regular hexagons arranged in an array and assembled by precision welding or brazing techniques to form an integral structure similar to a flat plate or block. This dense and axially connected honeycomb channel can effectively divide and guide turbulent airflow, transforming its lateral pulsations into axially stable flow, thereby achieving the purpose of rectifying, homogenizing the flow field and reducing turbulence.

[0003] The production process for these dense honeycomb structures is as follows: First, two parallel thin plates, processed by precision stamping, are stacked together. Then, using special welding techniques (such as roll welding or laser welding), these stacked thin plates are welded together to form a honeycomb module formed by stacking multiple thin plates. The precision of the stacking and welding determines the forming precision of the honeycomb module.

[0004] However, existing technologies have some problems: when stacking and welding honeycomb sheets, the honeycomb sheets first need to be aligned and stacked. Since the bent parts of two honeycomb sheets need to fit together, whether it is manual or automated equipment, there will inevitably be slight translational or angular errors in the identification and clamping of the micron-level positioning reference. Secondly, during the welding process, local non-uniform heat input will cause material expansion and contraction, resulting in internal stress and warping deformation. However, the honeycomb structure has a significant geometric cumulative effect. The slight alignment offset on each thin layer will increase linearly or exponentially after multiple layers are stacked, eventually leading to overall distortion, non-parallelism and other macroscopic defects in the lattice structure, which seriously damages its core functions of flow equalization and rectification, causing unacceptable performance deviations. Therefore, we propose a honeycomb sheet stacking positioning mechanism for a wind tunnel honeycomb module welding device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a honeycomb sheet stacking and positioning mechanism for a wind tunnel honeycomb module welding device. By setting positioning components and corresponding positioning plates according to the structure of the honeycomb tube, the positioning components support and position the honeycomb sheets, maintaining precise positioning accuracy of the honeycomb sheets throughout the welding process, thereby ensuring the welding accuracy of the honeycomb module.

[0006] The purpose of this utility model is achieved as follows: A honeycomb sheet stacking and positioning mechanism for a wind tunnel honeycomb module welding device includes an upper positioning component installed on a limiting mechanism of a welding platform. The upper positioning component is arranged in a spliced ​​structure and includes a first positioning component and a second positioning component. The first positioning component and the second positioning component are symmetrically distributed. A positioning member is provided between the first positioning component and the second positioning component. The positioning member is arranged to correspond to the honeycomb tube aperture of the honeycomb module. The positioning member penetrates the honeycomb tube, and both sides of the positioning member are respectively inserted into the first positioning component and the second positioning component.

[0007] Optionally, the first positioning component includes a first positioning plate and a first side plate. The first positioning plate and the first side plate are arranged perpendicularly and connected by bolts. The first positioning plate has positioning holes, which are set based on the position of the honeycomb tubes in the honeycomb module, and the positioning holes correspond one-to-one with the honeycomb tubes.

[0008] Optionally, a boss is provided on the first side plate. The boss is rectangular. The first side plate is connected to the limiting mechanism of the welding platform. The boss is correspondingly arranged with the groove of the limiting mechanism. Two sets of first positioning holes are provided on the first side plate. The two sets of first positioning holes are connected to the limiting mechanism by bolts.

[0009] Optionally, the second positioning component includes a second positioning plate and a second side plate, the second positioning plate being disposed corresponding to the second positioning plate, the second positioning plate being disposed perpendicular to the second side plate, and being connected by bolts.

[0010] Optionally, a connecting block is provided on the second side plate, the connecting block is engaged with the limiting mechanism, and a second positioning hole is provided on the second side plate, the second positioning hole is connected to the limiting mechanism by bolts.

[0011] Optionally, the positioning component includes a working section and a connecting section. The connecting section is correspondingly arranged with the positioning circular hole, the working section is correspondingly arranged with the honeycomb tube and passes through the honeycomb tube, and the connecting section is distributed on both sides of the working section and is respectively inserted into the first positioning plate and the second positioning plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application constructs a rigid skeleton by passing the working section of the positioning component through the honeycomb tube and tightly inserting it with the symmetrical upper positioning component using the connecting sections on both sides. This allows each honeycomb piece to obtain bottom support and top clamping, locking it in a predetermined position, eliminating the slight displacement and rotation caused by uncertainties such as uneven clamping force, visual deviation and operation vibration in the traditional stacking process. This ensures that the hexagonal core of each honeycomb layer is precisely aligned with the lower layer with extremely high precision, thereby effectively suppressing the overall structural distortion caused by the accumulation of tiny offsets, and ensuring that the final flow uniformity and rectification performance of the wind tunnel honeycomb module meets the design requirements in terms of consistency and reliability. 2. By setting a sliding boss and a snap-fit ​​connecting block, the positioning mechanism can be conveniently and quickly adapted to honeycomb modules of different sizes for a wide range of adjustments through sliding connection, and can also ensure absolute stability in working condition through double locking and multi-point high-strength fixation, eliminating vibration and displacement during the welding process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 6 The honeycomb panel stacking and positioning mechanism of the wind tunnel honeycomb module welding device shown includes an upper positioning component 1 installed on a limiting mechanism of the welding platform. The upper positioning component 1 is arranged in a spliced ​​structure and includes a first positioning component 2 and a second positioning component 3. The first positioning component 2 and the second positioning component 3 are symmetrically distributed. A positioning element 4 is provided between the first positioning component 2 and the second positioning component 3. The positioning element 4 is arranged to correspond to the honeycomb tube aperture of the honeycomb module. The positioning element 4 passes through the honeycomb tube. The two sides of the positioning element 4 are respectively inserted into the first positioning component 2 and the second positioning component 3. The positioning element 4 includes a working section 41 and a connecting section 42. The connecting section 42 is arranged to correspond to the positioning circular hole 23. The working section 41 is arranged to correspond to the honeycomb tube and passes through the honeycomb tube. The connecting section 42 is distributed on both sides of the working section 41 and is respectively inserted into the first positioning plate 21 and the second positioning plate 31.

[0018] It should be noted that the upper positioning component 1 provided in this application is installed on the limiting mechanism of the welding platform and is installed in a vertical direction, with each layer connected to ensure the stacking accuracy of each layer of honeycomb sheets. In addition, a horizontal reference line for the layer height and a vertical reference line for the weld position matching the honeycomb tube are provided on the inner surface of the upper positioning component 1 for comparing the position accuracy of each layer of honeycomb sheets.

[0019] Furthermore, the symmetrically distributed upper positioning components 1 and positioning elements 4 form a rigid skeleton, firmly clamping the honeycomb tube to prevent any slight displacement or rotation during the stacking process, ensuring that the absolute position of each honeycomb sheet is precisely aligned in three-dimensional space, thus solving the problem of cumulative deviation caused by visual errors and clamping jitter in traditional stacking. Secondly, the setting of transverse and longitudinal reference lines on the inner surface provides operators with an intuitive and rapid visual calibration basis, enabling real-time comparison and fine-tuning of layer height and weld position, simplifying the complex positioning process into efficient visual inspection, and greatly improving production efficiency and repeatability accuracy. Specifically, the first positioning component 2 includes a first positioning plate 21 and a first side plate 22. The first positioning plate 21 and the first side plate 22 are arranged perpendicularly and connected by bolts. The first positioning plate 21 has a positioning hole 23. The positioning hole 23 is set based on the position of the honeycomb tube in the honeycomb module. The positioning hole 23 corresponds to the honeycomb tube one by one. The second positioning component 3 includes a second positioning plate 31 and a second side plate 32. The second positioning plate 31 is arranged correspondingly to the second positioning plate 32. The second positioning plate 31 and the second side plate 32 are arranged perpendicularly and connected by bolts.

[0020] Furthermore, each positioning element 4 penetrating the positioning hole 23 not only provides a stable bottom support for the current layer of honeycomb sheet, preventing it from sinking or shifting under gravity, but also forms a vertical constraint force on the cover layer honeycomb sheet of the upper layer, firmly locking the honeycomb sheet in the predetermined position. This makes the honeycomb sheet, positioning element 4, and positioning plate form a stable overall frame, eliminating the floating and shaking problems caused by poor clamping or external interference in traditional stacking. It ensures that the hexagonal core of each layer of honeycomb sheet can be precisely aligned with the lower layer with extremely high precision, thereby effectively suppressing the overall structural distortion and precision reduction caused by the accumulation of small offsets, and ensuring the consistency and reliability of the final current sharing and rectification performance of the honeycomb module. Specifically, a boss 24 is provided on the first side plate 22. The boss 24 is rectangular. The first side plate 22 is connected to the limiting mechanism of the welding platform. The boss 24 is correspondingly set with the groove of the limiting mechanism. Two sets of first positioning holes 25 are provided on the first side plate 22. The two sets of first positioning holes 25 are connected to the limiting mechanism by bolts. A connecting block 33 is provided on the second side plate 32. The connecting block 33 is engaged with the limiting mechanism. A second positioning hole 34 is provided on the second side plate 32. The second positioning hole 34 is connected to the limiting mechanism by bolts.

[0021] Furthermore, the first side plate 22 and the second side plate 32 are respectively connected to the column of the limiting mechanism. After the connecting block 33 of the second side plate 32 is engaged with the limiting mechanism, it is fixedly connected by bolts. The boss 24 of the first side plate 22 can be slidably connected with the groove of the limiting mechanism and the fixing range can be adjusted through two sets of first positioning holes 25, thereby adjusting the cellular module.

[0022] Furthermore, the sliding fit between the boss 24 and the groove of the first side plate 22, along with the locking of the bolts in the positioning holes, allows the entire assembly to move smoothly and be precisely positioned within a small range on the limiting mechanism, meeting the installation requirements of honeycomb modules of different sizes. The second side plate 32 adopts a double fixing method of "first snap-fit, then bolt," which ensures absolute stability and zero-gap connection between the positioning mechanism and the base, eliminating any displacement caused by vibration during welding. This ensures the adaptability of the equipment to changes in product size and the ease of adjustment, while the multi-point, high-strength bolt fixing locks in the final precise position, thereby ensuring that the stacking accuracy of each batch of honeycomb modules of different specifications can be stably reproduced and guaranteed, greatly improving the stability of the process and production efficiency.

[0023] In summary, this application constructs a rigid skeleton by having the working section 41 of the positioning element 4 penetrate the honeycomb tube and tightly connect it with the symmetrical upper positioning component 1 using the connecting sections 42 on both sides. This allows each honeycomb piece to obtain bottom support and top clamping, and be locked in a predetermined position, eliminating the slight displacement and rotation caused by uncertainties such as uneven clamping force, visual deviation and operation vibration in the traditional stacking process. This ensures that the hexagonal core of each honeycomb layer is precisely aligned with the lower layer with extremely high precision, thereby effectively suppressing the overall structural distortion caused by the accumulation of tiny offsets, and ensuring that the final flow uniformity and rectification performance of the wind tunnel honeycomb module meets the design requirements in terms of consistency and reliability. By setting a sliding boss 24 and a snap-fit ​​connecting block 33, the positioning mechanism can be conveniently and quickly adapted to honeycomb modules of different sizes for wide-range adjustment through sliding connection, and can also ensure absolute stability in working condition through double locking and multi-point high-strength fixation, eliminating vibration and displacement during the welding process.

[0024] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
