[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.

[0025] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] To facilitate understanding of the multilayer material drilling tool and system provided in this application embodiment, its application scenario will be explained first. The multilayer material drilling tool and system provided in this application embodiment are used to improve the drilling efficiency of multilayer materials and reduce labor intensity. The tabletop of an air-floating glass breaking table is composed of composite non-metallic materials: an upper layer of felt and a lower layer of wood. More than 1000 air-floating holes need to be processed on the tabletop. The original air-floating hole processing was completed in two steps: first, using a leather punch to manually punch holes in the felt layer sequentially; second, using a hand drill to drill through the wood at the locations where the felt layer was punched. Due to the large number of holes, this process was labor-intensive, time-consuming, and inefficient. Therefore, this application embodiment provides a multilayer material drilling tool and system to improve the drilling efficiency of multilayer materials and reduce labor intensity. The following detailed description, in conjunction with specific accompanying drawings, illustrates the embodiments.

[0028] refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a multilayer material drill provided in an embodiment of this application.

[0029] exist Figure 1 In this application embodiment, a drilling tool for multilayer materials is provided, comprising: a drilling bit 1 and a cutting bit 2 arranged coaxially, wherein,

[0030] The drilling bit and the cutting bit are assembled together.

[0031] An elastic element 3 is provided between the drilling bit and the cutting bit.

[0032] One end of the elastic element is connected to the cutting drill bit, and the other end is connected to a baffle 6;

[0033] The baffle is disposed inside the cutting drill bit;

[0034] The baffle plate abuts against the cutting drill bit;

[0035] The baffle is fitted onto the drill bit.

[0036] In the above technical solution, by setting a drilling bit and a cutting bit arranged coaxially, the drilling bit and the cutting bit are fitted together, and an elastic element is provided between the drilling bit and the cutting bit. One end of the elastic element is connected to the cutting bit, and the other end is connected to a baffle plate. The baffle plate is disposed inside the cutting bit. The baffle plate abuts against the cutting bit. The baffle plate is also fitted through the drilling bit. This improves the drilling efficiency of multilayer materials and reduces labor intensity.

[0037] Specifically, the beneficial effects include:

[0038] 1. Improve drilling efficiency

[0039] Advantages of collaborative operation: The coaxial arrangement of the drilling and cutting bits allows the drilling bit to first pre-drill holes in the composite material, creating entry conditions for the cutting bit. The cutting bit then follows to cut the borehole edges. This collaborative operation method completes both drilling and edge cutting in one step, avoiding the multi-step operation of drilling and edge cutting required in traditional methods. This significantly shortens the overall drilling time and thus greatly improves the drilling efficiency of composite materials.

[0040] Reduced repetitive positioning: Because the drilling and cutting bits are coaxial, there is no need for multiple positioning adjustments of the material during drilling. After a single positioning, the drilling and cutting bits can operate simultaneously or sequentially along a preset trajectory, reducing time wastage and operational errors caused by repetitive positioning and further improving work efficiency.

[0041] 2. Reduce labor intensity

[0042] Reduced manual operation steps: Traditional drilling operations for multi-layered materials require first drilling holes with a drill bit, and then changing to a cutting tool to cut the edges of the drilled holes, which is a cumbersome operation. The drilling tool in this technical solution integrates drilling and cutting functions, allowing operators to complete the entire drilling operation with just one tool. This reduces tool changes and operational steps, thus lowering the workload for operators.

[0043] Optimized force transmission: The elastic element acts as a buffer and transmits force effectively. During drilling, the elastic element automatically adjusts its compression level according to the material's hardness and the drilling depth, allowing the drilling and cutting bits to apply appropriate pressure to the cladding material. This ensures the quality of drilling and cutting while preventing operator fatigue caused by excessive force, thus reducing labor intensity.

[0044] 3. Ensure drilling quality

[0045] Elastic element buffering function: The elastic element can buffer the impact force generated during drilling, reducing damage to the cladding material. When the drilling bit and cutting bit come into contact with the material, the elastic element can absorb part of the impact energy, making the interaction force between the drill bit and the material more stable, thereby ensuring the accuracy and quality of drilling and cutting.

[0046] Positioning function of the baffle: The baffle is installed inside the cutting drill bit, abutting against the cutting drill bit and passing through the drilling drill bit. This structure allows the baffle to play a certain positioning role for the relative positions of the drilling and cutting drill bits, ensuring that they remain coaxial during operation, and further guaranteeing the quality of drilling and cutting.

[0047] In one specific implementation, the baffle is provided with a through hole 4, and the drilling bit is inserted into the through hole.

[0048] In one possible implementation, the elastic element is disposed between the drilling bit and the cutting bit.

[0049] In one possible implementation, the elastic element is detachably connected to the cutting drill bit.

[0050] In one possible implementation, the elastic element is detachably connected to the baffle.

[0051] In one specific implementation, the cutting drill bit is provided with a fixing bolt 5.

[0052] In one specific implementation, the drill bit is a twist drill bit.

[0053] In one specific implementation, the cutting drill bit is a knife-shaped cutting drill bit.

[0054] In one possible implementation, the elastic element is a spring.

[0055] The working process of the multilayer material drill is as follows: drilling of multilayer materials can be completed in one go. During drilling, the central twist drill bit first drills through the felt layer and the base layer, and then the blade-shaped cutting drill bit can cut the felt layer completely. When drilling is stopped and the drill is removed, the baffle can directly remove the cut felt layer, and there will be no phenomenon of felt accumulating on the drill bit, which can realize continuous drilling work.

[0056] This application also provides a drilling system, including a multilayer material drill as described in any one of the claims.

[0057] In the above technical solution, by setting a drilling bit and a cutting bit arranged coaxially, the drilling bit and the cutting bit are fitted together, and an elastic element is provided between the drilling bit and the cutting bit. One end of the elastic element is connected to the cutting bit, and the other end is connected to a baffle plate. The baffle plate is disposed inside the cutting bit. The baffle plate abuts against the cutting bit. The baffle plate is also fitted through the drilling bit. This improves the drilling efficiency of multilayer materials and reduces labor intensity.
