Technical Field

[0001] The utility model relates to the field of fine processing of thin-walled parts, and in particular to an assembled vacuum module and a modular universal vacuum tooling. Background Art

[0002] In the current aircraft parts production process, especially for finishing small batches of thin-walled parts, vacuum adsorption processing is the only way to ensure product quality and quality due to the large thin-walled areas of the parts.

[0003] However, this type of parts varies in size and shape, and previously required customized special vacuum tooling for processing. As more and more thin-walled parts of different shapes and sizes are processed, the number of vacuum tooling has also increased, the cost of vacuum tooling has increased, and it is difficult to manage.

[0004] At the same time, in case of inconsistent part sizes and vacuum adsorption surface heights, vacuum switching plates of different heights need to be configured on the basis of customized vacuum tooling. This leads to an increasing number of types and quantities of conversion plates. When clamping workpieces of different specifications, it is inconvenient to use, the clamping standards are not unified, and process personnel cannot achieve clamping standardization. Utility Model Content

[0005] The purpose of the utility model is to provide an assembled vacuum module and a modular universal vacuum tooling, which can reduce the application of customized vacuum tooling, thereby reducing processing costs; reduce the use of conversion plates, and ensure standardization of clamping.

[0006] The embodiment of the present utility model is achieved as follows:

[0007] An assembled vacuum module includes a vacuum module body, wherein a second annular groove and a third central groove are sequentially provided on the surface of the vacuum module body from the outside to the inside, and a first assembly hole for assembling a fastener is vertically penetrated through the center of the third central groove; a gap is provided between the second annular groove and the third central groove, and a blockable air source hole is vertically penetrated through the bottom of the gap, and when the blockable air source hole is in an air suction state, the area formed by the second annular groove and the third central groove serves as a first adsorption surface.

[0008] In a preferred embodiment of the present invention, a first annular groove is further provided outside the second annular groove, and a first sealing ring is mounted in the first annular groove.

[0009] In a preferred embodiment of the present invention, the vacuum module body further comprises a second sealing ring. When the second sealing ring is assembled into the second annular groove, the first adsorption surface is switched to an adsorption surface consisting of only the third central groove.

[0010] In a preferred embodiment of the present invention, the shape of the first assembly hole includes a hexagonal through hole, and the fastener includes a hexagonal screw.

[0011] In a preferred embodiment of the present invention, the assembled vacuum module further comprises a silicone plug, which, when assembled on the pluggable air source hole, blocks the air source in the corresponding area of the assembled vacuum module.

[0012] A modular universal vacuum tooling comprises any of the above-mentioned assembled vacuum modules, wherein the modular universal vacuum tooling is equipped with an assembled vacuum module to form a vacuum adsorption plane of the same height; or, the modular universal vacuum tooling is equipped with a plurality of assembled vacuum modules of different heights to form a highly customized vacuum adsorption plane according to the different shapes of parts; or, the modular universal vacuum tooling is equipped with an assembled vacuum module formed by combining a plurality of assembled vacuum modules of different heights to form a highly customized vacuum adsorption plane according to the different shapes of parts.

[0013] In a preferred embodiment of the present invention, the above-mentioned modular universal vacuum tooling includes: a vacuum main board, a vacuum groove is provided in the center of the surface of the vacuum main board, a plurality of vacuum groove bodies for placing assembled vacuum modules are provided in the vacuum groove, and each vacuum groove body is provided with an air hole that passes through the blockable air source hole; two vacuum air nozzles for gas extraction and release are provided on the side of the vacuum main board, and an air path connecting the vacuum air nozzle and each air hole is provided inside the vacuum main board.

A zero-point quick-change Latin is provided at the bottom of the sealing bottom plate, and the zero-point quick-change Latin is quickly connected to the machine tool.

[0016] The beneficial effects of the embodiments of the present utility model are:

[0017] 1. The modular universal vacuum tooling in the present invention can apply assembled vacuum modules to the vacuum tooling, so that the new vacuum tooling can adaptably replace assembled vacuum modules of different heights at different positions according to the different heights and positions at which parts need to be adsorbed, thereby forming a unique vacuum adsorption surface. Alternatively, by combining assembled vacuum modules of different heights, a vacuum adsorption surface that matches the shape of the part can be formed, thereby reducing the use of customized vacuum tooling and thus reducing processing costs.

[0038] First embodiment

[0039] Please refer to Figure 1-7 This embodiment provides a modular universal vacuum tooling, including a sealing base plate 100 and a vacuum main plate 200 arranged on the sealing base plate 100, wherein the sealing base plate 100 is used to quickly assemble the vacuum tooling on the machine tool, and the vacuum main plate 200 is used to adsorb aircraft parts and clamp aircraft thin-walled parts.

[0040] Specifically, the sealing bottom plate 100 in this embodiment is arranged at the bottom of the vacuum main board 200. The bottom of the sealing bottom plate 100 is provided with a zero-point quick-change Latin 101 and a screw through hole. The zero-point quick-change Latin 101 is quickly connected to the machine tool, and the screws are assembled at the screw through hole to connect with the vacuum main board 200.

[0041] The vacuum mainboard 200 in this embodiment is a rectangular plate, but other shapes are possible in other embodiments. A vacuum groove is provided in the center of its surface for accommodating each assembled vacuum module. The vacuum groove can also have other shapes. The vacuum groove is provided with multiple vacuum slots 201 for accommodating assembled vacuum modules. Each vacuum slot 201 is provided with an air hole 204 that communicates with the blockable air source hole on the assembled vacuum module.

[0042] In this embodiment, the vacuum tank body 201 at this location can be a real tank body for placing an assembled vacuum module. The side wall height of the vacuum tank body 201 is lower than the horizontal height of the vacuum main board 200. The space left can be used to assemble a sealing strip and to freely set the area and shape of the adsorption surface, which can be freely changed according to the size of the adsorption area of the processed parts.

[0043] It can also be a virtual space for placing assembled vacuum modules. For example, in order to make the assembly gap between assembled vacuum modules smaller, the vacuum tank body 201 actually only has the bottom of the tank body, and the bottom of the tank body has air holes, while the side walls on the four sides are used to circle the position of the assembled vacuum module tank body. The side walls are composed of four assembled vacuum modules, but the sealing effect is not as good as using sealing strips.

[0044] Furthermore, to facilitate assembly, an air column can be installed at the air hole location. This air column not only facilitates positioning and assembly of the assembled vacuum module 300, but also provides a stable supply of air to the blockable air source hole. Of course, it is also possible to omit the air column at the air hole location and use a latch for positioning during assembly. After assembly, the latch can be removed to achieve precise assembly, but the steps of installing and removing the latch will be increased.

[0045] Also, see Figure 3-7 A first assembly hole 307 for assembling a fastener is vertically provided at the center of the third center groove on the vacuum module body 301. A second assembly closed hole 202 corresponding to the position of the first assembly hole 307 is also provided at the center of each vacuum slot 201 of the vacuum mainboard 200. In this embodiment, the second assembly hole is a tightening threaded hole, which is used to insert a fastener 320 from the center of the assembled vacuum module 300. The fastener 320 is connected to the second assembly closed hole 202, thereby fastening the assembled vacuum module 300.

[0046] In this embodiment, the shape of the first assembly hole 307 includes a hexagonal through hole, and the fastener 320 includes a hexagonal screw. In other embodiments, other fasteners 320 can also be used for assembly. It is necessary to ensure that the fastener 320 is a hidden sealed connection.

[0047] Two vacuum air nozzles 203 for extracting and releasing gas are provided on the side of the vacuum mainboard 200, which are used to connect vacuum equipment. The interior of the vacuum mainboard 200 is provided with an air path connecting the vacuum air nozzles 203 and each air hole, so that the air path between the air channel and the assembled vacuum module 300 is connected.

[0048] The front side of the vacuum mainboard 200 in this embodiment is a working surface, and the tightening threaded holes, positioning precision holes, and pluggable gas source holes provided thereon are all distributed in a matrix manner.

[0049] For details, see Figure 3 In this embodiment, the assembled vacuum module 300 includes a vacuum module body 301. The surface of the vacuum module body 301 is sequentially provided with a second annular groove 302 and a third central groove 303 from the outside to the inside. A notch 304 is provided on the side wall between the second annular groove 302 and the third central groove 303. A blockable air source hole 305 vertically penetrates the bottom of the notch 304. The blockable air source hole 305 is connected to the air hole of the vacuum mainboard 200, so that the second annular groove 302 and the third central groove 303 can form a vacuum adsorption area, enabling it to vacuum adsorb parts.

[0050] Compared with the traditional circular adsorption holes, the outer layer of the circular adsorption area in this embodiment is also provided with an annular adsorption area composed of a second annular groove 302, so that the side wall of the groove body with an inner circle and an outer square can support the thin-walled parts and prevent the adsorption point of the parts from being deformed due to excessive adsorption strength.

[0051] See Figure 4 The assembled vacuum module 300 also includes a silicone plug 310, which can be selectively installed in the pluggable air source hole 305 to release or block the air source. When the pluggable air source hole 305 is plugged with the silicone plug 310, the corresponding vacuum adsorption area of the assembled vacuum module 300 is blocked.

[0052] See Figure 6 To adjust the suction area of the assembled vacuum module 300, a second sealing ring 330 can be installed within the second annular groove 302. For smaller suction points, only the central circular suction area can be retained, thereby improving the adaptability of the tooling. Of course, in other embodiments, the suction area can be varied by adjusting the groove width and hole size to accommodate different suction shapes. However, this would increase the number of assembled vacuum modules 300.

[0053] The assembled vacuum module 300 disclosed in this embodiment has two heights. The first assembled vacuum module 340 is a basic height, which is flush with the height of the vacuum main board 200 after being assembled on the vacuum tooling. The second assembled vacuum module 350 is an additional height, which is used to act as a raised vacuum adsorption surface, such as the previous application of the vacuum switching plate.

[0054] In other embodiments, for example, when the second assembled vacuum modules 350 need to be combined, but two or three second assembled vacuum modules 350 still do not reach the height of the first assembled vacuum module 340 after being combined, in other embodiments, they can also be adaptively transformed into 3, 4, 5, or other integrated assembled vacuum modules 300 of different heights. Although the number and types of assembled vacuum modules 300 increase, the structure remains unchanged.

[0055] The assembled vacuum module 300 forms a vacuum adsorption plane with the same height through one assembled vacuum module 300, or forms a vacuum adsorption plane with variable height through multiple assembled vacuum modules 300 with different heights, or forms a vacuum adsorption plane with variable height by combining multiple assembled vacuum modules 300 with different heights.

[0056] Therefore, in use, the vacuum tooling can use a high-height assembled vacuum module 300 to be assembled in the vacuum tank to form a vacuum adsorption plane with the same height, which can be used for vacuum adsorption of general plate-type parts.

[0057] A variety of assembled vacuum modules 300 of different heights can also be assembled at different positions of the vacuum tank according to different parts, so as to form a customizable vacuum adsorption plane.

[0058] It can also be like what is disclosed in this embodiment, using a first assembled vacuum module 340 and a second assembled vacuum module 350 of two different heights. The two assembled vacuum modules 300 are combined to form vacuum modules of different heights. They can also be assembled in different positions of the vacuum groove according to different parts to form a customizable vacuum adsorption plane.

[0059] Specifically, the vacuum module body 301 is shaped like a rectangular block. While the assembled vacuum module 300 in this embodiment is a rectangular block, other shapes, such as a cylinder or a triangular prism, may also be employed in other embodiments. Accordingly, in this embodiment, the first and / or second annular grooves 302 are shaped like a square. These shapes can be adapted to accommodate different adsorption surfaces, such as circular or triangular adsorption surfaces, while still maintaining a circular adsorption surface.

[0060] At the same time, in order to increase the assembly stability of the assembled vacuum module 300, bumps or grooves can be set on the outer side of the assembled vacuum module 300, and it can be designed as a mortise and tenon structure similar to Lego blocks to enhance the stability between the two assembled vacuum modules 300 and facilitate assembly.

[0061] For further information, see Figure 5 In order to enhance the adsorption effect of the assembled vacuum module 300 , a first annular groove 306 is further provided outside the second annular groove 302 . When in use, a first sealing ring 360 is assembled in the first annular groove 306 .

[0062] In summary, the modular universal vacuum tooling in the utility model has strong interchangeability and modular design; independent area adsorption is safer and more reliable while providing effective vacuum adsorption force; it simplifies the processing plan of small batches of multi-specification thin-walled parts; it can reduce the cost of tooling manufacturing and processing, reduce the defective rate of part processing, and improve production efficiency. Compared with previous universal vacuum tooling, it is more practical and operational; the modular design is more practical in the processing of parts of different sizes.
