Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile processing, specifically to a multi-directional synchronous drilling machine tool for aluminum alloy frame profiles of electric vehicles. Background Technology

[0002] In industrial production, existing drilling machines face numerous limitations when processing profiles, especially those with holes on multiple sides. When profiles have holes on multiple sides, traditional drilling machines typically require three-axis multi-stage machining or more expensive five-axis CNC machining. This approach not only wastes significant resources but also reduces production efficiency. Furthermore, most previous drilling machines were designed for machining only a single face; machining holes on other sides required multiple dedicated drilling machines designed for different stages. This resulted in substantial time and manpower wasted during setup and transfer, severely impacting the continuity and efficiency of the entire production process.

[0003] The existing design of drilling machine tools has significant shortcomings in meeting complex machining requirements. For example, the design of existing drilling machine tools is only suitable for cases where a reference block is located after drilling and for machining single-sided holes. However, for cases where the drilling side corresponds to the clamping direction, the compressibility of air in the cylinder chamber often leads to unstable cylinder clamping during drilling, resulting in vibration. This vibration directly causes problems such as rough machined surfaces and out-of-round holes, affecting product quality and machining accuracy, and causing unnecessary losses to enterprises.

[0004] In summary, the problems of traditional drilling machine tools in multi-directional drilling and workpiece clamping stability severely restrict the efficiency and quality of industrial production. Therefore, researching and designing a novel multi-directional synchronous drilling machine tool for aluminum alloy frame profiles of electric vehicles to overcome the shortcomings of existing technologies is of great significance.

[0036] This embodiment discloses a multi-directional synchronous drilling machine for aluminum alloy frame profiles for electric vehicles, used for simultaneously drilling holes in multiple directions on the frame profile 35. The frame profile 35 includes an upper wall, a side wall, a bottom wall, a lower side wall, and an upper side wall connected in sequence. The upper side wall is connected to the upper wall to form a hollow irregular frame profile with a pentagonal cross-section. The multi-directional synchronous drilling machine for aluminum alloy frame profiles for electric vehicles is described below. Figure 1 and Figure 2 As shown, the system includes a worktable 1, a worktable support 2, an X-axis clamping mechanism, a Y-axis clamping mechanism, a Z-axis clamping mechanism, and a drilling mechanism. The worktable support 2 is located below the worktable 1 to support it. The X-axis clamping mechanism is located on the upper surface of the worktable 1 and is used to clamp the skeleton profile 35 in the X-axis direction. The Y-axis clamping mechanism is located on the upper surface of the worktable 1 and is used to clamp the skeleton profile 35 in the Y-axis direction. The Z-axis clamping mechanism is connected to the worktable 1 and is used to clamp the skeleton profile 35 in the Z-axis direction. The drilling mechanism includes a first drilling mechanism, a second drilling mechanism, and a third drilling mechanism. The first drilling mechanism is located on the upper surface of the worktable 1 and is used to drill holes in the side wall of the skeleton profile 35. The second drilling mechanism is located below the worktable 1 and is used to drill holes in the lower side wall of the skeleton profile 35. The third drilling mechanism is located below the worktable 1 and is used to drill holes in the bottom wall of the skeleton profile 35.

[0037] It should be noted that, as a preferred embodiment, such as Figure 1 and Figure 2 As shown, the X-axis clamping mechanism includes an X-axis push-clamping cylinder 3, an X-axis cylinder support 4, an X-axis push-clamping block 5, and an X-axis support 6. The X-axis push-clamping cylinder 3 is connected to the upper surface of the worktable 1 via the X-axis cylinder support 4. The cylinder rod of the X-axis push-clamping cylinder 3 is located at one end of the skeleton profile 35 in the X-axis direction, which can effectively provide a stable pushing force to ensure the stability and machining accuracy of the skeleton profile 35 during drilling. The X-axis cylinder support 4 is an I-shaped support. The I-shaped design not only enhances the stability of the support but also improves the overall rigidity of the X-axis cylinder support 4, effectively reducing the vibration of the X-axis push-clamping cylinder 3 during drilling, thereby reducing the vibration of the skeleton profile 35 and ensuring the drilling accuracy and surface quality. The X-axis pusher block 5 is connected to the upper surface of the worktable 1 via the X-axis support 6. The X-axis pusher block 5 is located at the other end of the skeleton profile 35 in the X-axis direction. The X-axis pusher block 5 cooperates with the cylinder rod of the X-axis pusher cylinder 3 to clamp the skeleton profile 35. The X-axis support 6 is an L-shaped support, which includes a first horizontal plate 6-1 and a first vertical plate 6-2 connected to each other. The first horizontal plate 6-1 is connected to the upper surface of the worktable 1, and the first vertical plate 6-2 is connected to the X-axis pusher block 5. A first reinforcing rib 6-3 is provided between the first horizontal plate 6-1 and the first vertical plate 6-2. By setting the first reinforcing rib 6-3, the structural strength and rigidity of the X-axis support 6 are further enhanced, the load-bearing capacity and stability of the X-axis support 6 are improved, and the X-axis support 6 can better withstand the pushing force and maintain the stability of the skeleton profile 35, thereby ensuring the smooth progress of the processing.

[0038] It should be noted that, as a preferred embodiment, the upper surface of the worktable 1 may be provided with multiple Z-axis clamping mechanisms. A design challenge arises when the drilling direction is opposite to the cylinder clamping direction. Because the air inside the cylinder is compressible, the clamping cylinder vibrates when the drilling machine advances to drill. To avoid this, the number of clamping cylinders at the corresponding drilling location needs to be increased to increase the clamping force. Therefore, in this embodiment, multiple Z-axis clamping mechanisms are provided on the upper surface of the worktable 1.

[0039] It should be noted that, as a preferred embodiment, such as Figure 3 As shown, the Z-axis clamping mechanism includes a Z-axis clamping cylinder 7, a Z-axis cylinder support 8, a clamping arm 9, a clamping head 10, a stop block 11, and a Z-axis support 12. The Z-axis clamping cylinder 7 is connected to the upper surface of the worktable 1 via the Z-axis cylinder support 8. The Z-axis clamping cylinder 7 can provide a stable vertical clamping force, ensuring the stability of the skeleton profile 35 during drilling and improving machining accuracy. One end of the clamping arm 9 is connected to the Z-axis clamping cylinder 7, and the other end of the clamping arm 9 is equipped with a clamping head 10. The clamping head 10 is located on one side of the skeleton profile 35 in the Z-axis direction. This design allows the clamping arm 9 to effectively transmit the force of the clamping cylinder to the clamping head 10, achieving precise clamping of the skeleton profile 35. At the same time, the structural design of the clamping arm 9 allows it to be flexibly adjusted within a certain range to adapt to skeleton profiles 35 of different sizes and shapes, improving the versatility and applicability of the equipment. The Z-axis cylinder support 8 is also equipped with a stop 11, which is located below one side of the pressure arm 9. The stop 11 provides a stable support point during the clamping process of the pressure arm 9, preventing the pressure arm 9 from shifting or shaking when pressure is applied. It also prevents the pressure arm 9 from pressing down too much, which could cause the skeleton profile 35 to be deformed. This ensures the stability and reliability of the clamping process, helps to improve the clamping accuracy, and reduces machining errors. The Z-axis support 12 is located on the upper surface of the worktable 1, and the Z-axis support 12 corresponds to the position of the pressure head 10. The Z-axis support 12 provides a stable support for the pressure head 10, enhancing the rigidity and stability of the entire clamping system. This corresponding arrangement ensures that the pressure head 10 can evenly distribute pressure when clamping the workpiece, avoiding excessive local pressure, thereby protecting the workpiece surface, preventing deformation or damage, and improving machining quality and yield.

[0040] More specifically, in this embodiment, the Z-axis cylinder support seat 8 is screwed and pinped and mounted on the worktable 1, the pressure arm 9 is screwed and mounted on the Z-axis clamping cylinder 7, and the pressure head 10 is screwed and mounted on the pressure arm 9.

[0041] It should be noted that, as a preferred embodiment, the upper surface of the workbench 1 is provided with two Y-axis clamping mechanisms, which are arranged on both sides along the 35X axis direction of the skeleton profile.

[0042] It should be noted that, as a preferred embodiment, the Y-axis clamping mechanism includes a Y-axis direction pressing cylinder 13, a Y-axis cylinder support 14, and a Y-axis direction pressing block 15. The Y-axis direction pressing cylinder 13 is connected to the upper surface of the worktable 1 through the Y-axis cylinder support 14. The cylinder rod of the Y-axis direction pressing cylinder 13 is located on one side of the skeleton profile 35 in the Y-axis direction. The Y-axis direction pressing cylinder 13 can provide a stable Y-axis direction pressing force, ensuring that the workpiece remains stable during drilling and effectively preventing the skeleton profile 35 from moving, thereby ensuring machining accuracy. The Y-axis cylinder support 14 is an I-shaped support, similar to the X-axis cylinder support 4. This structure not only enhances the stability of the support but also improves the overall rigidity, effectively reducing vibration, thereby ensuring drilling accuracy and surface quality. The design of the Y-axis cylinder support 14 allows it to evenly distribute pressure when bearing the force of the pressing cylinder, reducing stress concentration and extending the service life of the Y-axis cylinder support 14. The Y-axis push block 15 is connected to the Z-axis cylinder support 8. The Y-axis push block 15 is positioned on the other side of the frame profile 35 along the Y-axis. The cylinder rod of the Y-axis push cylinder 13 corresponds to the position of the Y-axis push block 15. This design allows the Y-axis push block 15 to accurately transmit the thrust of the cylinder rod of the Y-axis push cylinder 13 to the frame profile 35, achieving precise tightening of the frame profile 35. Simultaneously, the size and shape of the Y-axis push block 15 can be optimized according to the specific requirements of the frame profile 35 to ensure good contact with the frame profile 35 and improve the tightening effect. Furthermore, the Y-axis push block 15 being positioned on the Z-axis cylinder support 8 not only reduces the use of machine tool materials but also enhances the stability of the entire clamping system. This allows for more reliable fixation of the frame profile 35 during Y-axis tightening, reducing machining errors caused by frame profile 35 displacement and ensuring consistent and reliable machining quality.

[0043] It should be noted that, as a preferred embodiment, such as Figure 1 and Figure 2As shown, the first drilling mechanism includes a first drilling machine 16, a first bottom adjusting seat 17, a first drilling and milling head 18, a first guide sleeve 19, a first adjusting connecting block 20, a first guide sleeve support seat 21, and a first reference block 22. The first drilling machine 16 is connected to the upper surface of the worktable 1 through the first bottom adjusting seat 17. The first bottom adjusting seat 17 not only provides a stable foundation, but also allows the first drilling machine 16 to be finely adjusted in position and angle during installation and use to adapt to different processing needs, thereby improving the flexibility and applicability of the equipment. The first drill bit 18 extends from inside the first drilling machine 16. The first guide sleeve 19 is set at the hole to be drilled position on the skeleton profile 35. The first drill bit 18 passes through the first guide sleeve 19. The first drill bit 18 is used to drill holes in the side wall of the skeleton profile 35. By setting the first guide sleeve 19, the movement trajectory of the first drill bit 18 can be guided, avoiding excessive protrusion of the first drill bit 18 and causing shaking, ensuring the accuracy of the drilling direction, reducing offset and error, and improving the processing quality. The first guide sleeve 19 is connected to the first guide sleeve support 21 through the first adjustment connecting block 20. The first guide sleeve support 21 is set on the upper surface of the worktable 1. This connection structure not only enhances the stability of the first guide sleeve 19, but also allows for quick adjustment or replacement when needed to adapt to different specifications of drill bits or processing requirements. The first guide sleeve support 21 is set on the upper surface of the worktable 1, providing a stable support for the entire guiding system, ensuring that it will not be displaced due to vibration or other external forces during the drilling process, thereby ensuring the stability and accuracy of the processing. The first reference block 22 is set on the upper surface of the worktable 1, and the position of the first reference block 22 corresponds to that of the first drilling head 18. The first reference block 22 provides a precise positioning reference for drilling operations, ensuring that each drilling is performed in the correct position, which greatly improves the consistency and repeatability of processing and reduces the scrap rate caused by position deviation. In addition, the position of the first reference block 22 corresponding to the first drilling head 18 can also ensure that the skeleton profile 35 will not be bent by the drill bit during drilling. At the same time, the drilling direction corresponds to the reference block fixing structure, which can effectively prevent processing vibration.

[0044] It should be noted that, as a preferred embodiment, the first drilling machine 16 includes a single-head first drilling machine 16-1 and a double-head first drilling machine 16-2. The single-head first drilling machine 16-1 has one first drilling and milling head 18, and the double-head first drilling machine 16-2 has two first drilling and milling heads 18. The single-head first drilling machine 16-1 with one first drilling and milling head 18 is suitable for high-precision machining of a single hole position; while the double-head first drilling machine 16-2 with two first drilling and milling heads 18 can simultaneously machine two holes, significantly improving work efficiency, and is especially suitable for tasks requiring multi-hole machining on the same plane. This design not only improves the versatility of the equipment but also optimizes the production process, reducing processing time and equipment space occupation.

[0045] It should be noted that, as a preferred embodiment, such as Figure 1-4 As shown, the second drilling mechanism includes a second drilling machine 23, a second bottom adjusting seat 24, a second drilling head 25, a second guide sleeve 26, a second adjusting connecting block 27, and a second guide sleeve support 28. The second drilling machine 23 is connected to the lower surface of the worktable 1 via the second bottom adjusting seat 24. The second bottom adjusting seat 24 not only provides stable support for the second drilling machine 23 but also allows for precise adjustment of its position and angle to adapt to drilling needs at different locations, enhancing the flexibility and applicability of the equipment. The second drilling head 25 extends from inside the second drilling machine 23, as shown... Figure 3 As shown, the second guide sleeve 26 is positioned at the hole location on the skeleton profile 35. The worktable 1 has a first opening, through which the second drill bit 25 passes. The second drill bit 25 is used to drill holes in the lower sidewall of the skeleton profile 35. The second guide sleeve 26 ensures the accuracy of the drilling direction of the second drill bit 25, reduces offset and error, improves processing quality, protects the second drill bit 25, extends its service life, and prevents the drill bit 25 from protruding too far and causing shaking, which would affect drilling accuracy. The second guide sleeve 26 is connected to the second guide sleeve support 28 via the second adjusting connecting block 27. The second guide sleeve support 28 is located on the upper surface of the worktable 1. The second adjusting connecting block 27 and the second guide sleeve support 28 not only enhance the stability of the guide sleeve but also allow for quick adjustment or replacement when needed to adapt to different specifications of drill bits or processing requirements, improving the versatility and maintenance convenience of the equipment.

[0046] It should be noted that, as a preferred embodiment, such as Figure 1-4As shown, the third drilling mechanism includes a third drilling machine 29, a third bottom adjusting seat 30, a third drilling head 31, a third guide sleeve 32, a third adjusting connecting block 33, and a third guide sleeve support 34. The third drilling machine 29 is connected to the lower surface of the worktable 1 through the third bottom adjusting seat 30. The third bottom adjusting seat 30 provides stable support for the third drilling machine 29, allowing for fine adjustments in position and angle, thus enhancing the flexibility of the equipment. The third drilling head 31 extends from inside the third drilling machine 29. The third guide sleeve 32 is set at the hole to be drilled position on the skeleton profile 35. The worktable 1 has a second opening. The third drilling head 31 passes through the second opening and the third guide sleeve 32. The third drilling machine 29 is used to drill holes in the bottom wall of the skeleton profile 35. The third guide sleeve 32 is used to guide the movement trajectory of the third drilling head 31, ensuring accurate drilling direction, reducing errors, improving quality, and protecting the drilling head. The third guide sleeve 32 can also prevent the third drilling head 31 from protruding too far and causing shaking, which would affect the drilling accuracy. The third guide sleeve 32 is connected to the third guide sleeve support 34 via the third adjusting connecting block 33. The third guide sleeve support 34 is located on the upper surface of the worktable 1. The third adjusting connecting block 33 and the third guide sleeve support 34 can enhance the stability of the third guide sleeve 32, facilitate the quick adjustment or replacement of the third guide sleeve 32, adapt to different specifications of drilling and milling heads, and improve versatility and maintenance convenience.

[0047] More specifically, in this embodiment, the first drilling head 18, the second drilling head 25, and the third drilling head 31 are all drilling heads, not ordinary twist drills. This increases the rotary cutting capability, reduces the thrust, and avoids the vibration of the cylinder as the drilling machine advances, enabling simultaneous drilling in any multiple directions. The first bottom adjusting seat 17, the second bottom adjusting seat 24, and the third bottom adjusting seat 30 can all be mounted on the worktable 1 using screws and pins. Each of the first bottom adjusting seat 17, the second bottom adjusting seat 24, and the third bottom adjusting seat 30 can have a 3mm shim provided in each direction. The drilling center position of the first drilling machine 16, the second drilling head 25, and the third drilling machine 29 can be adjusted by increasing or decreasing the shim thickness, ensuring that the machining accuracy is controlled within ±0.05mm relative to the reference. In this embodiment, the position of the first drilling and milling head 18 can correspond to the position of the Z-axis cylinder support 8, and the first reference block 22 can be set on the Z-axis cylinder support 8. More specifically, the first reference block 22 can be fixed on the Z-axis cylinder support 8 by screws and pins.

[0048] In this embodiment, the X-axis pushing cylinder 3 is fixed to the X-axis cylinder support 4 by screws, the X-axis pushing block 5 is fixed to the X-axis support 6 by screws and pins, the Z-axis pressing cylinder 7 is fixed to the Z-axis cylinder support 8 by screws, the Y-axis pushing cylinder 13 is fixed to the Y-axis cylinder support 14 by screws, the Y-axis pushing block 15 is fixed to the Z-axis cylinder support 8 by screws and pins, the first drilling machine 16 is fixed to the first bottom adjusting seat 17 by screws, the second drilling machine 23 is fixed to the second bottom adjusting seat 24 by screws, and the third drilling machine 29 is fixed to the third bottom adjusting seat 30 by screws.

[0049] In use, the skeleton profile 35 to be drilled is aligned with the X-axis push block 5, Z-axis support 12, and Y-axis push block 15. After ensuring alignment, the processing button is pressed, and the X-axis push cylinder 3, Y-axis push cylinder 13, and Z-axis clamping cylinder 7 clamp the skeleton profile 35. Each of the X-axis push cylinder 3, Y-axis push cylinder 13, and Z-axis clamping cylinder 7 is equipped with a magnetic induction switch to sense whether the clamping is in place. After clamping, the first drilling machine 16, the second drilling head 25, and the third drilling machine 29 advance forward to drill. After drilling is completed, they automatically retract. After the first drilling machine 16, the second drilling head 25, and the third drilling machine 29 retract, the X-axis push cylinder 3, Y-axis push cylinder 13, and Z-axis clamping cylinder 7 open, and the drilled skeleton profile 35 is removed.
