Description

Gasket processing method, gasket processing equipment and gasket Technical Field

[0001] This invention relates to the field of gasket processing technology, and in particular to a gasket processing method, a gasket processing apparatus, and a gasket. Background Technology

[0002] Aircraft structures are complex and contain a large number of parts. Regardless of the assembly process, datum system, and tolerance allocation scheme used, gaps are inevitable at some part mating surfaces. When gaps occur at part mating surfaces, aircraft assembly coordination methods mainly include adding shims and adding allowances to metal parts. Shims are generally non-structural shims and are used as needed based on the actual assembly requirements.

[0003] Aircraft assembly requires the manufacture of numerous gaskets, typically less than 1 millimeter thick. The common method for manufacturing these gaskets is using peelable gaskets, which are traditionally made by hand, often by tearing them apart on the assembly line. However, this method is unsuitable for gaskets of varying thickness or with curved shapes because manual operation is inaccurate, slow, and physically demanding.

[0004] In existing technologies, for the manufacturing of gaskets with non-straight gaps, a method has been proposed to use multiple peelable gaskets of different thicknesses bonded to a base to form a multi-step surface gasket, thereby achieving the fitting of curved surface gaps. However, this requires preparing gaskets of various thicknesses; and according to the external dimensions of the gap, the required gasket shape must be milled multiple times and then bonded, making the processing flow lengthy; due to the interlayer forces of the peelable gaskets, milling not only easily causes delamination of the peelable gaskets, but also makes the milling of the external shape very difficult. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0034] In a first aspect, the present invention discloses a gasket processing method for manufacturing gaskets with non-straight gaps. The gasket is used to be installed at assembly gaps. The gasket to be processed comprises multiple stacked and bonded unit gaskets. The gasket to be processed is obtained by processing the gasket, as shown in the flowchart in Figure 1. The gasket processing method includes the following steps:

[0035] Step 1: Measure the target mounting location of the gasket to obtain the assembly gap dimension;

[0036] Step 2: Determine the preset thickness and number of layers of the unit gasket 10 of the gasket to be processed based on the maximum value of the assembly gap along the thickness direction of the gasket; and determine the processing parameters of each layer of unit gasket 10;

[0037] Step 3: Cut each layer of unit gasket 10 of the gasket to be processed 1 according to the processing parameters and peel off the excess part 11 after cutting.

[0038] First, the dimensions of the assembly gap are obtained by measuring the target installation location of the gasket, thus determining the shape and size of the assembly gap. Then, the preset thickness and number of layers of the unit gasket 10 constituting the gasket 1 to be processed are determined based on the maximum value of the assembly gap dimension along the gasket thickness direction. The preset thickness of the unit gasket 10 is set according to the required gasket precision at the target installation location. The optimal solution is when the product of the preset thickness and the number of layers results in a thickness of the gasket 1 to be processed that exactly matches the maximum value of the assembly gap dimension along the gasket thickness direction, eliminating the need for additional milling of the vertical dimension. Based on this, the processing parameters for each layer of unit gasket 10 to obtain the required gasket are obtained. Stepped gaskets are processed layer by layer to fit non-straight gaps. The depth of each vertical cut is an integer multiple of the preset thickness, improving the efficiency of subsequent cutting processes. After cutting each layer of unit gasket 10 according to the obtained processing parameters, it is easier to peel off the excess portion 11 layer by layer to obtain the required gasket, effectively avoiding delamination or damage to the gasket due to irregular force during the peeling of the excess portion 11. Using this gasket processing method simplifies the processing steps and reduces processing difficulty, effectively improving processing efficiency. In actual production, a large number of unit gaskets 10 are usually prepared in advance, whose actual thickness is much smaller than the actual gap size, and the preset thickness of the unit gasket 10 is several times its actual thickness.

[0039] Furthermore, based on the data processing of the assembly gap dimensions, the digitized model of the gasket used for non-straight gaps is transformed into a multi-step surface model, and suitable processing parameters are calculated, including the number of layers of the unit gasket 10 to be cut and the coordinates to be cut corresponding to each layer of unit gasket 10, and the cutting path is automatically planned. It can be understood that the coordinates to be cut are the coordinates of each point on the edge of each layer of unit gasket 10 to be cut in the horizontal plane.

[0040] For example, compared to manual operation, CNC machine tool processing in this embodiment can greatly improve both accuracy and efficiency. The excess portion 11 after peeling and cutting can be peeled off manually, or more preferably mechanically.

[0041] Specifically, step 3 can be implemented as follows: cut each layer of unit gasket 10 of the gasket 1 to be processed into an integer multiple of the preset thickness of the unit gasket 10 in the vertical direction upward or downward. After all the cutting of each layer of unit gasket 10 is completed, the excess part 11 after cutting is peeled off all at once. This method is especially suitable when the overall thickness of the required gasket is not large and the thickness of the gasket 1 to be processed is less than the cutting edge length of the cutting tool. Using this method to process the gasket makes the process simpler and more convenient, and further improves the processing efficiency.

[0042] For example, the cutting tool has an initial position in the vertical direction, which is higher than the upper surface of the uppermost unit gasket 10 of the gasket 1 to be processed. When cutting upwards in the vertical direction, the cutting tool first starts from a point on the coordinate of the lowermost unit gasket 10 to be cut, and cuts to a depth equal to the product of a preset thickness and the layer number of that layer. The layer number is determined as follows: the uppermost unit gasket 10 is the first layer, the next uppermost unit gasket 10 is the second layer, and so on. The cutting tool moves sequentially along the coordinate of the horizontal plane to be cut. After cutting the lowermost unit gasket 10, the cutting tool returns to the initial position and moves to the coordinate of the next lower layer to be cut, then descends to the next lower layer's cutting depth, and then... The cutting tool moves sequentially along the horizontal plane until the cutting of the unit gasket 10 in that layer is completed; or, after the bottom unit gasket 10 is completed, the cutting tool may not return to the initial position, but only move vertically upward by a preset thickness, and then move horizontally to the coordinate to be cut of the second to last unit gasket 10, and cut to the starting point. Then the cutting tool moves sequentially along the coordinate to be cut of that layer until the cutting of the unit gasket 10 in that layer is completed; and so on, processing layer by layer until all the cutting of each unit gasket 10 is completed, and finally peeling off the excess part 11 after cutting.

[0043] Understandably, when cutting vertically downwards, the cutting tool starts from the starting point of the coordinates to be cut on the topmost unit pad 10 and cuts vertically downwards by a preset thickness. Then, the cutting tool moves along the coordinates to be cut on that layer sequentially until the cutting of that unit pad 10 is completed. According to the coordinates to be cut on the second layer unit pad 10, the cutting tool can return to its initial position, move to the cutting starting point of the second layer, and then descend vertically by twice the preset distance to start cutting; or it can move horizontally to the cutting starting point of the second layer without returning to its initial position, then descend by a preset thickness, and then move along the coordinates to be cut on that layer sequentially until the cutting of that unit pad 10 is completed. This process is repeated layer by layer until all the cutting of each layer of unit pad 10 is completed. Finally, the excess part 11 after cutting is peeled off, which has the same effect as cutting vertically upwards.

[0044] Optionally, step 3 can also be specifically implemented as follows: cut vertically downwards with a preset thickness of the unit gasket 10, and peel off the excess part 11 after each layer of unit gasket 10 is cut; then repeat the above steps to continue cutting and peeling off the next layer of unit gasket 10 until the cutting and peeling of each layer of unit gasket 10 is completed. Each time, the cutting tool only needs to cut a preset thickness depth vertically, and the processing of the unit gasket 10 is completed according to the processing parameters. The force and wear range of the cutting tool are kept within a smaller range, which saves the service life of the cutting tool, ensures processing accuracy, avoids wasting cutting time, and ensures the improvement of effective cutting rate.

[0045] Secondly, this invention discloses a gasket processing apparatus applicable to gasket processing methods as described in any of the above-described schemes. As shown in FIG2, the gasket processing apparatus includes a processing platform 4, a control module, and a cutting module 2. The gasket 1 to be processed is placed on the processing platform 4. The cutting module 2 is positioned above the processing platform 4 and can translate in a first direction and a second direction parallel to and perpendicular to the processing platform 4. It also moves vertically in units of an integer multiple of a preset thickness, which can reduce the influence of interlayer forces on gasket processing. The processing parameters of each layer of the required gasket 10 are obtained using the control module. Simultaneously, the cutting module 2 is communicatively connected to the control module, receiving the processing parameters transmitted by the control module and cutting the unit gasket 10 according to the processing parameters before peeling off the excess portion 11. Exemplarily, the cutting module 2 can be configured as a cutting tool in the above-described gasket processing method.

[0046] Specifically, the control module includes a measurement conversion component, which measures the assembly gap size at the target mounting location of the gasket. The assembly gap size includes the external dimensions of various points along the assembly gap contour. By measuring the assembly gap size at the target mounting location, the maximum value of the assembly gap size along the gasket thickness direction can be obtained to determine the preset thickness and number of layers of the unit gasket 10 of the gasket to be processed. This is used to prepare for the fabrication of the gasket 1. The gasket 1 to be processed includes multiple stacked and bonded unit gaskets 10. The material is simple, making it easy to fabricate the gasket 1 and meeting the preparation and processing requirements of different gaskets. It eliminates the need for milling the external shape and secondary bonding, and has lower requirements for the manufacturing environment. Based on the data processing of the assembly gap size, the digital model of the gasket used for non-straight gaps is converted into a multi-step surface model. The height of each step is consistent with the preset thickness, and the contour size of the assembly gap at each unit step height is set as the cutting coordinate corresponding to each layer of unit gasket 10.

[0047] Furthermore, the measuring conversion component is connected to the cutting module 2 to obtain the processing parameters of the unit gasket 10. The gasket 1 to be processed with a preset thickness and number of layers is placed on the processing platform 4, so that the cutting module 2 can automatically plan the cutting path according to the processing parameters and the coordinates to be cut corresponding to each layer of unit gasket 10.

[0048] Preferably, the cutting module 2 is configured to rotate around a vertical axis, solving the problem of insufficient smoothness in cutting the rounded positions of the required gaskets and avoiding issues such as insufficient fit of the manufactured gaskets to the assembly gap, which could lead to poor filling effects. It can better cut arc-shaped contours, resulting in gaskets with higher precision and better performance. The cutting module 2's ultrasonic vibration processing capability is even better, as it can alleviate the compression of the gasket 1 under processing, preventing the possibility of gasket delamination. The cutting tool of the cutting module 2 can use a narrower and sharper alloy steel blade as a metal engraving tool, which is more wear-resistant, sharper, and has higher cutting efficiency.

[0049] Optionally, the cutting module 2 is further equipped with an automatic removal component for mechanically removing the excess portion 11 after the gasket 1 is cut. For example, when the cutting module 2 cuts vertically downwards at a preset thickness for each unit gasket 10, after each layer of unit gasket 10 is cut, the cutting module 2 moves vertically downwards by a preset thickness from the starting point of the coordinates to be cut in that layer. Then, the cutting module 2 moves along the coordinates to be cut in that layer until the cutting of that layer of unit gasket 10 is completed. At this point, the removal component is inserted between the excess portion 11 after the cutting of the just-completed unit gasket 10 and the next layer of unit gasket 10 to be processed, lifting and cutting off the excess portion 11. After each layer of unit gasket 10 is cut, the excess portion 11 can be mechanically and automatically removed, thus further improving efficiency and quality.

[0050] For example, manual peeling can also be performed by using an auxiliary tool configured as a thin, hard plastic blade that can be inserted between two adjacent, stacked unit gaskets 10, making it easier for operators to perform targeted peeling and trimming of some more complex-shaped gaskets.

[0051] In this embodiment, the gasket processing device further includes a gasket 3, which is placed between the gasket 1 to be processed and the processing platform 4 to prevent the cutting module 2 from damaging the processing platform 4. For example, the gasket can be made of aluminum alloy or plastic, which is inexpensive and reduces wear and tear on the cutting module 2.

[0052] Optionally, the gasket processing device also includes a clamping module, which is configured to fix the gasket 1 to be processed on the processing platform 4. In order to better clamp and align the gasket 1 to be processed, it is convenient for the cutting module 2 to cut and process it.

[0053] Thirdly, the present invention discloses a gasket processed using the above-mentioned gasket processing device and gasket processing method, which is less prone to delamination, and has improved quality and precision, greatly shortens the processing flow, and can better meet the needs of aircraft assembly for gaskets with a large number of non-straight gaps.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
