Description

Technical Field

[0001] This utility model relates to the field of tooling assembly technology, and in particular to a composite material T-shaped vacuum tooling. Background Technology

[0002] Composite material T-shaped vacuum tooling is mainly used in the manufacturing of complex structures such as aircraft wing frames, achieving high-precision forming through vacuum-assisted molding technology. The tooling is large in size and complex in structure, consisting of a universal base and multiple sets of combined modules (mirror parts). However, the existing universal base and multiple sets of combined modules are inconvenient to disassemble and assemble, and the positioning is not accurate. This leads to the impact on positioning accuracy and inconvenience when repeatedly installing multiple sets of combined modules. Therefore, we propose a composite material T-shaped vacuum tooling to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a composite T-shaped vacuum tooling.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a composite T-shaped vacuum tooling, comprising a base, reference blocks, positioning pins, through holes, magnetic chucks, a vacuum module, a bottom plate, positioning holes, a panel, panel holes, bushings, ventilation grooves, air inlets, and airtight grooves. Multiple reference blocks are fixedly installed on the surface of the base. Positioning pins are provided on both sides of the surface edge of each reference block. Multiple through holes are provided on the surface of the base. Multiple magnetic chucks are fixedly installed on the surface of each reference block. A vacuum module is movably installed on the surfaces of both the reference blocks and the magnetic chucks. The vacuum module includes a bottom plate. Positioning holes are provided on both sides of the surface of the bottom plate. A panel is fixedly installed on the top of the bottom plate. A panel hole is provided at the corner of the panel surface. A bushing is movably installed inside the panel hole. Ventilation grooves and air inlets are provided on the surface of the panel. An airtight groove is provided at the edge of the panel surface.

[0005] Preferably, the positioning pin corresponds to the positioning hole, and the positioning pin and the positioning hole are in clearance fit.

[0006] Preferably, the magnetic chucks are all positioned between each pair of reference blocks.

[0007] Preferably, the bushing and the panel hole are in a clearance fit.

[0008] Compared with the prior art, this utility model has the following advantages: By installing the vacuum module onto both sides of the magnetic chuck and the reference block, and aligning the first and second positioning holes, the positioning pins are fitted into the positioning holes, thus enabling the vacuum module to be positioned and aligned accurately. Then, by activating the magnetic chuck, the bottom plate of the vacuum module is attracted to it, allowing the vacuum module to be stably installed on the base. When the vacuum module needs to be disassembled, the magnetic chuck is deactivated, preventing it from attracting the bottom plate. The positioning pins can then be removed from the first and second positioning holes to complete the disassembly of the vacuum module. This facilitates easy installation and disassembly of the vacuum module, allowing for repeated installation while maintaining positioning accuracy. Attached Figure Description

[0011] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0012] like Figure 1-3 The T-shaped vacuum fixture shown includes a base 1, a reference block 2, a positioning pin 3, a through hole 4, a magnetic chuck 5, a vacuum module 6, a base plate 7, a second positioning hole 8, a panel 9, a panel hole 10, a bushing 11, a ventilation groove 12, an air inlet 13, and an airtight groove 14. Multiple reference blocks 2 are fixedly mounted on the surface of the base 1. Positioning pins 3 are provided on both sides of the edge of the reference block 2. Multiple through holes 4 are provided on the surface of the base 1. Multiple magnetic chucks 5 are fixedly mounted on the surface of the reference blocks 2. A vacuum module 6 is movably mounted on the surfaces of the reference blocks 2 and the magnetic chucks 5. The vacuum module 6 includes a base plate 7. Positioning holes 8 are provided on both sides of the surface of the base plate 7. A panel 9 is fixedly mounted on the top of the base plate 7. A panel hole 10 is provided at the corner of the surface of the panel 9. A bushing 11 is movably mounted inside the panel hole 10. Ventilation grooves 12 and air inlets 13 are provided on the surface of the panel 9. An airtight groove 14 is provided at the edge of the surface of the panel 9.

[0013] In this embodiment, the positioning pin 3 corresponds to the positioning hole 8, and the positioning pin 3 and the positioning hole 8 are in clearance fit.

[0014] In practical use, by installing the vacuum module 6 on both sides of the magnetic chuck 5 and the reference block 2, and by corresponding the first positioning hole 3 and the second positioning hole 8, the positioning pin 4 can be fitted into the positioning hole 8, thereby positioning and aligning the vacuum module 6 to ensure positioning accuracy.

[0015] In this embodiment, the magnetic chucks 5 are all arranged between each pair of reference blocks 2.

[0016] In practical use, by activating the magnetic chuck 5, the magnetic chuck 5 can adhere to the bottom plate 7 of the vacuum module 6, allowing the vacuum module 6 to be stably installed on the base 1. When the vacuum module 6 needs to be disassembled, the magnetic chuck 5 is deactivated, so that the magnetic chuck 5 does not exert any attraction on the bottom plate 7. Then, the positioning pin 4 can be removed from the first positioning hole 3 and the second positioning hole 8 to complete the disassembly of the vacuum module 6. This makes the vacuum module 6 easy to install and remove, and facilitates repeated installation of the vacuum module 6, while ensuring positioning accuracy during repeated installation.

[0017] In this embodiment, the bushing 11 and the panel hole 10 are in clearance fit.

[0018] In practical use, bushing 11 can be used for the machining and positioning of composite parts.

[0019] The working principle of the composite T-shaped vacuum tooling mentioned in this utility model is as follows: In use, by installing the vacuum module 6 on both sides of the magnetic chuck 5 and the reference block 2, and by corresponding the first positioning hole 3 and the second positioning hole 8, the positioning pin 4 is fitted into the positioning hole 8, thereby positioning and aligning the vacuum module 6 to ensure positioning accuracy. Then, by activating the magnetic chuck 5, the magnetic chuck 5 can adhere to the bottom plate 7 of the vacuum module 6, allowing the vacuum module 6 to be stably installed on the base 1. When the vacuum module 6 needs to be disassembled, the magnetic chuck 5 is deactivated, so that the magnetic chuck 5 will not exert any attraction on the bottom plate 7. Then, the positioning pin 4 can be removed from the first positioning hole 3 and the second positioning hole 8 to complete the disassembly of the vacuum module 6. This makes the vacuum module 6 easy to install and remove, and facilitates repeated installation of the vacuum module 6, while ensuring positioning accuracy during repeated installation.
