Description

Technical Field

[0001] This invention relates to the technical field of titanium alloy processing, and in particular to a magnetic suction auxiliary device for drilling titanium alloys and its processing method. Background Technology

[0002] Titanium alloys are widely used in shipbuilding, aerospace, and chemical equipment due to their excellent strength-to-weight ratio, corrosion resistance, and high-temperature performance. However, titanium alloys are non-magnetic materials with extremely low magnetic permeability, preventing magnetic drills from being directly attached to the surface of titanium alloy substrates for drilling. Current technologies for drilling titanium alloy substrates typically employ the following methods: first, using large machine tools for fixed processing, but this involves large equipment investment, a large footprint, and difficulty in moving large workpieces; second, using specialized clamps for clamping, but the design and manufacturing cycle of these clamps is long and costly, and the clamping accuracy for curved substrates is difficult to guarantee; third, using a handheld electric drill, but this results in poor drilling accuracy, high labor intensity, and low safety. Magnetic drills, as efficient drilling devices, use electromagnetic attraction to fix the drill to the workpiece surface, offering advantages such as ease of operation, accurate positioning, and high efficiency. However, due to the non-magnetic nature of titanium alloys, magnetic drills cannot be directly applied to drilling titanium alloy substrates, severely limiting their application in the titanium alloy processing field. Summary of the Invention

[0003] The invention aims to solve at least one of the technical problems existing in the prior art. It provides a magnetic auxiliary device for drilling titanium alloys and its processing method. Through the cooperation of an adaptable magnetic conductor and a fixing clamp, the overall structure is simple, small in size, and flexible in movement and use. It can complete drilling in environments with limited processing space or when the workpiece is difficult to move. It is low-cost, enables magnetic drilling on non-magnetic and hard materials with high drilling accuracy, reduces labor intensity, and improves operational safety.

[0004] To achieve the above objectives, the present invention provides a magnetic suction auxiliary device for drilling titanium alloys, comprising: The adapter magnetic conductor includes a mating surface and a magnetic suction surface arranged opposite to each other. The mating surface is used to fit against the titanium alloy base to be processed, and the magnetic suction surface is used to magnetically position the magnetic drill bit. The adapter magnetic conductor is provided with a positioning through groove, which passes through the mating surface and the magnetic suction surface respectively, for positioning and passing through the drill bit of the magnetic drill bit to process the titanium alloy base. The fixing clamp includes a first clamping plate, a second clamping plate, and a fixing component; The first clamping plate and the second clamping plate are arranged opposite to each other to clamp the adapter magnetic conductor and the titanium alloy base between the first clamping plate and the second clamping plate. The first clamping plate has a first through hole, and the second clamping plate has a second through hole. The fastener passes through the first through hole and the second through hole and is used to tighten the first clamping plate and the second clamping plate together.

[0005] As a preferred embodiment, the positioning slots are provided in multiple ways, and adjacent positioning slots are spaced apart by reinforcing ribs.

[0006] As a preferred embodiment, the positioning slot is a long strip-shaped slot, allowing the drill bit of the magnetic drill to move within the positioning slot and drill holes sequentially at multiple locations to be processed.

[0007] As a preferred embodiment, a receiving space is formed between one end of the first clamping plate and one end of the second clamping plate, the receiving space being used to clamp the adapter magnetic conductor and the titanium alloy base between the first clamping plate and the second clamping plate.

[0008] As a preferred embodiment, the material of the adapter magnetic conductor is low-carbon steel or electrical pure iron.

[0009] As a preferred embodiment, the thickness of the adapting magnetic conductor is a mm, where a ≥ 12.

[0010] As a preferred embodiment, the weight of the adapter magnet is set between 3KG and 8KG.

[0011] A method for processing a magnetically assisted device for drilling titanium alloys, comprising the following steps: The magnetically assisted device is used to drill holes in a titanium alloy base using a magnetic drill. The preset drilling position step involves marking the preset drilling positions on the surface to be machined of the titanium alloy base; In the pre-positioning step of the magnetic adapter, the magnetic adapter is placed on the titanium alloy base, the mating surface is mated with the surface to be processed, and the pre-drilled hole is located in the positioning groove. In the step of fixing the adapter magnetic conductor, the adapter magnetic conductor and the titanium alloy base are placed between the first clamping plate and the second clamping plate, and the distance between the first clamping plate and the second clamping plate is shortened by the fixing member, so that the adapter magnetic conductor and the titanium alloy base are clamped together. The steps for positioning and installing the magnetic drill are as follows: pass the drill bit end of the magnetic drill through the positioning slot and align it with one of the preset drilling positions, and turn on the magnetic drill switch. The magnetic base of the magnetic drill is then magnetically connected to the magnetic surface. The drilling process involves controlling the rotation of the magnetic drill bit to drill into a preset drilling position, thereby completing the drilling process.

[0012] As a preferred option, the following steps are also included: For adjacent drilling operations, turn off the magnetic drill switch, the magnetic base of the magnetic drill separates from the magnetic surface, and repeat the positioning and installation steps of the magnetic drill and the drilling steps.

[0013] As a preferred embodiment, in the pre-positioning step of the adapter magnetic conductor, the adapter magnetic conductor further has a first positioning surface for abutting against the side wall of the titanium alloy base. The first positioning surface is disposed on one side between the magnetic attraction surface and the contact surface. One side of the titanium alloy base has a second positioning surface. The first positioning surface and the second positioning surface are aligned so that the preset drilling position is located in the positioning through groove.

[0014] Compared with existing technologies, the magnetic suction auxiliary device and processing method for drilling titanium alloys according to embodiments of the present invention have the following advantages: The adapter magnetic material includes a mating surface and a magnetic suction surface arranged opposite each other. The mating surface is used to mat with the titanium alloy base to be processed, so that the adapter magnetic material contacts the titanium alloy base for easy processing. The magnetic suction surface is used for magnetic positioning with the magnetic drill. The magnetic suction surface acts as the adsorption platform of the magnetic drill, directly magnetically connected to the magnetic suction seat of the magnetic drill. The adapter magnetic material is then clamped to the titanium alloy base by a fixing clamp, thereby achieving indirect fixation of the magnetic drill on a non-magnetic titanium alloy base. The positioning through-slots penetrate the mating surface and the magnetic suction surface, allowing the drill bit of the magnetic drill to be positioned and pass through for processing the titanium alloy base. The positioning through-slots provide a precise guiding channel for the drill bit. The drill bit is positioned and passes through the through-slots, directly drilling into the titanium alloy base below, ensuring the accuracy of the drilling position and avoiding interference between the drill bit and the adapter magnetic material. The fixing clamp includes a first clamping plate, a second clamping plate, and a fixing member. The first clamping plate and the second clamping plate are arranged opposite to each other to clamp the adapter magnetic conductor and the titanium alloy base between the first clamping plate and the second clamping plate. The fixing clamp acts as a clamping actuator to fix the adapter magnetic conductor and the titanium alloy base, preventing relative displacement during drilling and ensuring machining accuracy and operational safety. The first clamping plate has a first through hole, and the second clamping plate has a second through hole. The fixing member passes through the first through hole and the second through hole to pull the first clamping plate and the second clamping plate together. By tightening the fixing member, the first clamping plate and the second clamping plate are brought closer together, thereby generating a clamping force to firmly clamp and fix the adapter magnetic conductor and the titanium alloy base. The operation is simple and adjustable, and can adapt to titanium alloy bases of different thicknesses. The magnetic auxiliary device for drilling titanium alloys of this invention has a simple overall structure, small size, and flexible mobility. It can complete drilling operations in environments with limited processing space or where it is inconvenient to move the workpiece. At the same time, it is low-cost, avoiding the large investment and large footprint of purchasing large machine tools. By magnetically connecting the magnetic surface of the adapter magnetic material with the magnetic base of the magnetic drill, and further fixing the adapter magnetic material to the non-magnetic and rigid titanium alloy base by fixing components, the magnetic drill can perform drilling operations on non-magnetic and rigid materials. The drilling accuracy is high, the labor intensity is reduced, and the operation safety is improved, avoiding the problems of poor drilling accuracy, high labor intensity, and low safety caused by manual hand-held electric drills.

[0026] like Figures 1 to 5 As shown, a preferred embodiment of the magnetic suction auxiliary device for drilling titanium alloys according to the present invention includes: The adapter magnetic conductor 10 includes a mating surface 11 and a magnetic attraction surface 12 arranged opposite to each other. The mating surface 11 is used to mat with the titanium alloy base 30 to be processed, and the magnetic attraction surface 12 is used to magnetically position the magnetic drill 40. The adapter magnetic conductor 10 is provided with a positioning through groove 13, which passes through the mating surface 11 and the magnetic attraction surface 12 respectively, for positioning and passing through the drill bit 41 of the magnetic drill 40 to process the titanium alloy base 30. The fixing clamp 20 includes a first clamping plate 21, a second clamping plate 23, and a fixing member 25; The first clamping plate 21 and the second clamping plate 23 are arranged opposite to each other to clamp the adapter magnetic conductor 10 and the titanium alloy base 30 between the first clamping plate 21 and the second clamping plate 23. The first clamping plate 21 is provided with a first through hole 22, and the second clamping plate 23 is provided with a second through hole 24. The fastener 25 passes through the first through hole 22 and the second through hole 24 to tighten the first clamping plate 21 and the second clamping plate 23 together.

[0027] The magnetic suction auxiliary device for drilling titanium alloys of the present invention includes a magnetically conductive body 10, comprising a mating surface 11 and a magnetic suction surface 12 arranged opposite to each other. The mating surface 11 is used to fit against the titanium alloy base 30 to be processed, so that the magnetically conductive body 10 and the titanium alloy base 30 come into contact to facilitate processing. The magnetic suction surface 12 is used to magnetically position the magnetically suction drill 40. The magnetic suction surface 12 serves as the adsorption platform of the magnetically suction drill 40 and is directly magnetically connected to the magnetic suction seat 42 of the magnetically suction drill 40. The magnetically conductive body 10 is then clamped to the titanium alloy base 30 by a fixing clamp 20, thereby achieving indirect fixation of the magnetically suction drill 40 on the non-magnetically conductive titanium alloy base 30. The positioning slot 13 penetrates both the mating surface 11 and the magnetic surface 12, allowing the drill bit 41 of the magnetic drill 40 to be positioned and pass through for machining the titanium alloy base 30. The positioning slot 13 provides a precise guiding channel for the drill bit 41, which is positioned and passes through the slot to directly drill into the titanium alloy base 30 below. This ensures the accuracy of the drilling position and avoids interference between the drill bit 41 and the matching magnetic conductor 10. The fixing clamp 20 includes a first clamping plate 21, a second clamping plate 23, and a fixing member 25. The first clamping plate 21 and the second clamping plate 23 are arranged opposite to each other to clamp the matching magnetic conductor 10 and the titanium alloy base 30 between the first clamping plate 21 and the second clamping plate 23. The fixing clamp 20 acts as a clamping actuator to fix the matching magnetic conductor 10 and the titanium alloy base 30, preventing relative displacement during drilling and ensuring machining accuracy and operational safety. The first clamping plate 21 has a first through hole 22, and the second clamping plate 23 has a second through hole 24. A fixing member 25 passes through the first through hole 22 and the second through hole 24 to tighten the first clamping plate 21 and the second clamping plate 23 together. By tightening the fixing member 25, the first clamping plate 21 and the second clamping plate 23 are brought closer together, thereby generating a clamping force to firmly hold and fix the adapter magnetic conductor 10 and the titanium alloy base 30. The operation is simple and adjustable, adaptable to titanium alloy bases 30 of different thicknesses, and convenient. The magnetic suction auxiliary device for titanium alloy drilling of the present invention has a simple overall structure, small size, and flexible movement, enabling drilling in environments with limited processing space or where workpiece movement is inconvenient. Furthermore, it is low-cost, avoiding the large investment and large footprint of purchasing large machine tools. The magnetic surface 12 of the magnetic adapter 10 is magnetically connected to the magnetic base 42 of the magnetic drill 40. The magnetic adapter 10 is further fixed to the non-magnetic and hard titanium alloy base 30 by the fixing member 25, so that the magnetic drill 40 can drill holes in non-magnetic and hard materials. The drilling accuracy is high, the labor intensity is reduced and the operation safety is improved. It avoids the problems of poor drilling accuracy, high labor intensity and low safety caused by manual hand-held electric drill.

[0028] As one embodiment, such as Figure 1 and Figure 5 As shown, fastener 25 consists of bolts and nuts.

[0029] As one embodiment, such as Figures 2 to 4 As shown, the magnetic suction surface 12 has a planar structure. This planar positioning surface allows for complete contact between surfaces, avoiding the instability caused by point or line contact that may occur with curved or irregularly shaped surfaces. This ensures a stable and reliable fit between the two positioning surfaces during the positioning process. The surface roughness Ra is less than or equal to 3.2 μm, ensuring the microscopic flatness of the positioning surface. This allows for a larger actual contact area between the first positioning surface 15 and the second positioning surface 33 during contact, avoiding the problem of excessive surface roughness leading to microscopic protrusion support and an insufficient actual contact area. The moderate roughness requirement ensures positioning accuracy without significantly increasing processing costs, achieving a good balance between performance and economy. The flatness is less than or equal to 0.05 mm, ensuring that the gap between the two surfaces is controlled within a very small range during contact, thereby eliminating local contact or tilting problems caused by planar deformation or processing errors.

[0030] As one embodiment, the surface of the adapter magnet 10 is galvanized or phosphated to improve wear resistance and rust prevention.

[0031] As one embodiment, the edge of the adapter magnet 10 is provided with a chamfer or rounded corner, with a chamfer size of 0.5mm to 2mm.

[0032] As one embodiment, such as Figure 1 As shown, both ends of the adapter magnetic conductor 10 are fixed to the titanium alloy base 30 by fixing clips 20.

[0033] Furthermore, such as Figures 2 to 4 As shown, multiple positioning slots 13 are provided, with adjacent positioning slots 13 spaced apart by reinforcing ribs 14. The multiple positioning slots 13 allow the auxiliary device to be clamped and fixed at once, and then drilled sequentially at different positions on the titanium alloy base 30. This avoids repeated disassembly and reassembly of the fixing clamp 20; multiple holes can be drilled simply by moving the position of the magnetic drill 40, improving processing efficiency and avoiding repetitive positioning errors caused by repeated disassembly and reassembly of the device. The reinforcing ribs 14 spaced apart by adjacent positioning slots 13 serve a structural reinforcement function, preventing deformation or damage to the adapter magnetic conductor 10 under the attraction force of the magnetic drill 40 and the impact force of drilling. Simultaneously, the reinforcing ribs 14 ensure the relative positional accuracy between the positioning slots 13, ensuring consistent positioning references for multiple holes, thereby improving the overall drilling quality.

[0034] Furthermore, such as Figures 2 to 4As shown, the positioning slot 13 is an elongated slot, allowing the drill bit 41 of the magnetic drill 40 to move within it and sequentially drill multiple holes to be processed. The elongated shape of the positioning slot 13 enables the drill bit 41 to move along its extension direction, providing a basis for single-clamp, multi-point drilling, avoiding repeated positioning errors caused by multiple clamping, and improving processing efficiency and consistency of hole processing. When the drill bit 41 moves within the positioning slot 13, the sidewalls of the slot act as guides and limiters, ensuring that the drill bit 41 maintains an accurate drilling direction even after moving to different positions. Simultaneously, the drill bit 41 can sequentially process multiple preset drilling positions 32, achieving continuous operation without the need to disassemble the device during drilling, and the continuity of the positioning slot 13 ensures the positional accuracy between each hole.

[0035] Furthermore, such as Figure 1 and Figure 5 As shown, a receiving space 26 is formed between one end of the first clamping plate 21 and one end of the second clamping plate 23. The receiving space 26 is used to clamp the adapter magnetic conductor 10 and the titanium alloy base 30 between the first clamping plate 21 and the second clamping plate 23. The receiving space 26 is formed in the same end region of the first clamping plate 21 and the second clamping plate 23, allowing the adapter magnetic conductor 10 and the titanium alloy base 30 to be inserted from the end of the fixing clamp 20 without repeated disassembly and reassembly of the fixing member 25. Only loosening or tightening the fixing member 25 is required, thereby simplifying the clamping operation and improving the operating efficiency.

[0036] Furthermore, such as Figures 2 to 4 As shown, the material of the magnetic conductor 10 is low-carbon steel or electrical pure iron. Low-carbon steel has a high relative permeability, which can effectively conduct magnetic lines of force, allowing the magnetic base 42 of the magnetic drill 40 to firmly adhere. At the same time, low-carbon steel has good plasticity and processing properties, making it easy to process into the required shape through cutting, drilling, bending, and other processes, and it is inexpensive, suitable for mass production. Electrical pure iron is a high-purity iron-based soft magnetic material with extremely high relative permeability and extremely high saturation magnetic induction intensity, making it one of the materials with the best magnetic permeability among soft magnetic materials. Its high permeability and low coercivity can maximize the transmission of the electromagnetic attraction force of the magnetic drill 40, ensuring stable and reliable adsorption. Meanwhile, electrical pure iron has low hysteresis loss, and it is not easy to generate residual magnetism during repeated power-on and power-off processes of the magnetic drill 40, facilitating device disassembly.

[0037] As one embodiment, such as Figures 2 to 4 As shown, low-carbon steel is carbon steel with a carbon content of less than 0.25%.

[0038] As one embodiment, such as Figures 2 to 4 As shown, the permeability of the adapter magnetic material 10 is greater than or equal to 2000H / m.

[0039] Furthermore, such as Figures 2 to 4 As shown, the thickness of the adapter magnetic conductor 10 is a mm, where a ≥ 12. The adapter magnetic conductor 10 has a through-hole positioning groove 13, which weakens the strength of the adapter magnetic conductor 10 itself. If the thickness is insufficient, under the combined action of the magnetic drill 40's adsorption pressure and the drilling impact load, the adapter magnetic conductor 10 may bend and deform, even causing the positioning groove 13 to lose its geometric accuracy, affecting the accuracy of drilling guidance. The minimum thickness of 12 mm provides sufficient section modulus, enabling the adapter magnetic conductor 10 to have sufficient bending stiffness and impact resistance, ensuring structural stability during processing, while obtaining a stable and reliable adsorption force.

[0040] As one embodiment, such as Figures 2 to 4 As shown, the thickness of the adapter magnetic conductor 10 is set between 12mm and 20mm.

[0041] Furthermore, such as Figures 2 to 4 As shown, the weight of the adapter magnetic conductor 10 is set between 3KG and 8KG. The lower limit of 3kg ensures that the adapter magnetic conductor 10 has sufficient material volume, thereby guaranteeing its necessary structural rigidity to withstand drilling impact loads, while providing sufficient magnetic cross-section to prevent magnetic saturation and ensure stable and reliable adsorption of the magnetic drill 40; the upper limit of 8kg fully considers the actual needs of on-site operations, avoiding difficulties in handling, low clamping efficiency, and potential safety risks caused by excessive weight. This weight range allows the adapter magnetic conductor 10 to meet core functional requirements while also possessing good portability and ease of operation, making it particularly suitable for on-site drilling operations of large and medium-sized titanium alloy workpieces in shipbuilding, aerospace, and other fields.

[0042] In one embodiment, the length of the adapter magnet 10 is set to be between 300mm and 600mm, and the width is set to 100mm.

[0043] A method for manufacturing a magnetic suction auxiliary device for drilling titanium alloys, such as Figure 1 as well as Figures 5 to 7 As shown, the magnetic auxiliary device for drilling titanium alloys uses a magnetic drill 40 to drill holes in the titanium alloy base 30, including the following steps: The pre-marking drilling position step involves marking the pre-marked drilling position 32 on the surface 31 to be machined of the titanium alloy base 30. Precise marking of the drilling position on the titanium alloy base 30 before machining provides a clear positional reference for subsequent alignment of the positioning slot 13 and positioning of the drill bit 41. This step ensures the accuracy of the drilling position, avoids positional deviations caused by blind operation, and is a prerequisite for ensuring machining accuracy.

[0044] In the pre-positioning step of the magnetic adapter 10, the magnetic adapter 10 is placed on the titanium alloy base 30, with the contact surface 11 aligning with the surface to be processed 31, and the preset drilling position 32 located within the positioning groove 13. The magnetic adapter 10 is initially placed on the titanium alloy base 30, ensuring a tight fit between the contact surface 11 and the surface to be processed 31, while simultaneously ensuring that the preset drilling position 32 falls within the range of the positioning groove 13. This achieves alignment between the magnetic adapter 10 and the titanium alloy base 30, providing an accurate positional relationship for subsequent clamping and drilling. Through the guiding effect of the positioning groove 13, the path of the drill bit 41 is aligned with the preset drilling position 32, ensuring that the drilling position meets the requirements.

[0045] In the step of fixing the magnetic adapter 10, the magnetic adapter 10 and the titanium alloy base 30 are placed between the first clamping plate 21 and the second clamping plate 23. The distance between the first clamping plate 21 and the second clamping plate 23 is shortened by the fixing member 25, so that the magnetic adapter 10 and the titanium alloy base 30 are clamped together. The pre-positioned magnetic adapter 10 and the titanium alloy base 30 are then inserted into the receiving space 26 of the fixing clamp 20, and the clamping force is generated by tightening the fixing member 25 to firmly clamp the magnetic adapter 10 and the titanium alloy base 30 into a whole. This process changes the magnetic adapter 10 and the titanium alloy base 30 from a pre-positioned state to a fixed connection state, eliminating any possible relative displacement between them and ensuring that the entire device remains rigidly connected during the drilling process.

[0046] The steps for positioning and installing the magnetic drill are as follows: The end of the drill bit 41 of the magnetic drill 40 is passed through the positioning slot 13 and aligned with one of the preset drilling positions 32. The switch of the magnetic drill 40 is then activated, and the magnetic base 42 of the magnetic drill 40 is magnetically connected to the magnetic surface 12. The drill bit 41 of the magnetic drill 40 is passed through the positioning slot 13, ensuring precise alignment between the drill bit 41 and the preset drilling position 32. This achieves positioning of the magnetic drill 40 on the compatible magnetic guide body 10. The electromagnetic switch of the magnetic drill 40 is then activated, firmly attaching the magnetic base 42 of the magnetic drill 40 to the magnetic surface 12 of the compatible magnetic guide body 10, thus connecting the magnetic drill 40 to the compatible magnetic guide body 10. This achieves precise positioning and reliable attachment of the magnetic drill 40. During this process, the positioning slot 13 simultaneously serves as a guide and limiter, ensuring that the axis of the drill bit 41 coincides with the center of the preset drilling position 32. The electromagnetic adsorption of the magnetic drill 40 and the mechanical clamping of the fixing clamp 20 form a double fixation, which further enhances the stability of the processing system.

[0047] The drilling process involves controlling the rotation of the drill bit 41 of the magnetic drill 40 to drill into the preset drilling position 32, thus completing the drilling. The rotation function of the magnetic drill 40 is then activated to perform the actual drilling on the titanium alloy base 30. During this process, the positioning slot 13 continuously guides the drill bit 41, preventing it from shifting; the fixing clamp 20 maintains the relative fixation between the adapter magnet 10 and the titanium alloy base 30; the electromagnetic adsorption of the magnetic drill 40 ensures the overall stability of the device, achieving high-precision drilling of the titanium alloy base 30 and completing the entire process.

[0048] Furthermore, such as Figures 5 to 7 As shown, it also includes the following steps: For adjacent drilling operations, the magnetic drill 40 switch is turned off, separating the magnetic base 42 of the magnetic drill 40 from the magnetic surface 12. The positioning and installation steps of the magnetic drill 40 and the drilling steps are repeated. After completing a drilling operation, the magnetic drill 40 switch is first turned off, and its magnetic base 42 is separated from the magnetic surface 12. This ensures that the magnetic drill 40 is in a free state when moving to the next drilling position. Then, the positioning and installation steps of the magnetic drill and the drilling steps are repeated, so that the magnetic drill 40 is re-aligned with the next preset drilling position 32 and the machining is completed. The above steps are repeated until all preset drilling positions 32 are machined. The guiding effect of the positioning through groove 13 and the clamping and fixing effect of the fixing clamp 20 are fully utilized. Without disassembling the auxiliary device, the multi-hole high-efficiency machining of the titanium alloy base 30 is achieved, which not only ensures the relative positional accuracy between each drilling hole, but also improves the machining efficiency.

[0049] Furthermore, such as Figure 6As shown, in the pre-positioning step of the adapter magnetic conductor, the adapter magnetic conductor 10 also has a first positioning surface 15 for abutting against the side wall of the titanium alloy base 30. The first positioning surface 15 is disposed on one side between the magnetic attraction surface 12 and the contact surface 11. One side of the titanium alloy base 30 has a second positioning surface 33. The first positioning surface 15 and the second positioning surface 33 are aligned so that the preset drilling position 32 is located in the positioning through groove 13. The first positioning surface 15 on the adapter magnetic conductor 10 and the second positioning surface 33 on the titanium alloy base 30 cooperate with each other. When the two are aligned, the position of the adapter magnetic conductor 10 relative to the titanium alloy base 30 is uniquely and accurately determined, thereby ensuring that the preset drilling position 32 automatically falls into the range of the positioning through groove 13. There is no need for repeated adjustments and visual inspections by the operator, eliminating positioning errors caused by human operation and ensuring the consistency of the relative positions between each drilling position and the positioning through groove 13. This is particularly suitable for batch processing or multi-hole processing scenarios. At the same time, it simplifies the pre-positioning operation process. The operator only needs to align the first positioning surface 15 with the second positioning surface 33 to complete the precise positioning, which improves the clamping efficiency. Furthermore, the mechanical cooperation structure of the first positioning surface 15 and the second positioning surface 33 is not affected by the operator's skill level, which lowers the operation threshold and ensures that different operators can obtain consistent positioning accuracy. This makes the pre-positioning process of the auxiliary device more accurate, efficient and reliable, providing an accurate positioning basis for subsequent drilling processing.

[0050] As one embodiment, such as Figure 1 As shown, both the first positioning surface 15 and the positioning through groove 13 are arc-shaped and are used to process the flat and annular titanium alloy base 30. The titanium alloy base 30 has a second positioning surface 33, and the first positioning surface 15 is aligned with the second positioning surface 33.

[0051] As one embodiment, such as Figure 5 As shown, the magnetic drill 40 has a drill bit 41 for drilling. Different diameter drill bits 41 are selected according to the diameter of the hole. The width of the positioning through groove 13 is set to correspond to the diameter of the drill bit 41.

[0052] As one embodiment, such as Figure 7 As shown, the magnetic drill 40 is existing technology. The bottom of the magnetic drill 40 has a magnetic base 42. After the magnetic drill 40 is started, it can be magnetically connected to the magnetic surface 12 through the magnetic base 42.

[0053] In summary, this invention provides a magnetic suction auxiliary device and its processing method for drilling titanium alloys. By incorporating a matching magnetic guide 10 made of magnetically conductive material, the problem that non-magnetically conductive titanium alloy materials cannot be attracted by the magnetic drill 40 is solved, enabling the magnetic drill 40 to be used for drilling titanium alloy bases 30. The contact surface 11 of the matching magnetic guide 10 matches the surface 31 to be processed on the titanium alloy base 30, ensuring a tight fit between the matching magnetic guide 10 and the titanium alloy base 30, thus improving drilling accuracy and stability. The fixing clamp 20 enables precise positioning and reliable fixation of the matching magnetic guide 10, preventing displacement of the matching magnetic guide 10 and the titanium alloy base 30 during drilling. The magnetic suction auxiliary device has a simple structure, is easy to operate, and is inexpensive, improving drilling efficiency and processing quality of titanium alloy bases 30.

[0054] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
