Description

Technical Field

[0001] This utility model relates to the field of inspection tools for automobile production, specifically to an aluminum alloy bending tool that can drill reference holes. Background Technology

[0002] Existing bending gauges are widely used in aluminum profile processing; however, they have many shortcomings in practical use and urgently need further optimization and improvement. Currently, common bending gauges mainly focus on inspecting the surface contours of three-dimensional profile bending parts, which can provide preliminary dimensional and shape references for subsequent processing to some extent. However, the problem is that these gauges can only provide a relatively rough scribing reference, offering limited guidance for subsequent, more precise processing steps. In subsequent processing, workers often have to rely solely on visual alignment to process holes and other features. Because automotive aluminum alloy profile parts have extremely high requirements for hole position accuracy, needing to achieve a relative accuracy of Φ0.6 to the reference surface, while the contour accuracy of the bent three-dimensional curved surface relative to the reference surface also requires 1mm or even higher precision. Under such high-precision processing requirements, relying solely on visual alignment by workers makes it difficult to ensure the relative accuracy between the three-dimensional curved surface of the workpiece and the holes and other features processed later. This not only easily leads to machining errors in individual parts, but also makes it difficult to guarantee the positioning and consistency of each part during the machining process in mass production, thus seriously affecting product quality and production efficiency.

[0003] Furthermore, when workers visually inspect holes, it is difficult to accurately judge the spatial relationship between the curved surface and the processing features, which can easily lead to omissions or errors in processing. Moreover, visual inspection is easily affected by factors such as ambient light and worker fatigue, resulting in unstable processing quality and increasing the defect rate and rework costs.

[0004] In summary, existing aluminum alloy bending fixtures with drillable reference holes have significant shortcomings in providing precise positioning and guidance for subsequent processing, making it difficult to meet the processing requirements of modern high-precision aluminum alloy profile components. Therefore, it is essential to research and design a novel aluminum alloy bending fixture with drillable reference holes to overcome the deficiencies of existing technologies. Utility Model Content

[0034] This embodiment provides an aluminum alloy bending part inspection tool that can drill reference holes, such as... Figure 1 and Figure 2 As shown, a reference hole is made on the side wall of the aluminum alloy bent part 9 to check its quality. Figure 1 As shown, the system includes a base frame 1, a support device 2, a vertical clamping device, a side clamping device, a detection device, a drilling device 7, and a vibration damping device 8. The support device 2 is located on the upper surface of the base frame 1 and is used to support the aluminum alloy bent part 9. The vertical clamping device is located on the upper surface of the base frame 1 and is used to clamp the aluminum alloy bent part 9 in the vertical direction. The side clamping device is located on the upper surface of the base frame 1 and is used to clamp the aluminum alloy bent part 9 in the horizontal direction. The detection device includes a plane detection device 5 and a curved surface detection device 6. Both the plane detection device 5 and the curved surface detection device 6 are located on the upper surface of the base frame 1. The plane detection device 5 corresponds to the plane portion of the aluminum alloy bent part 9 and is used to detect the plane portion. The curved surface detection device 6 corresponds to the curved portion of the aluminum alloy bent part 9 and is used to detect the curved portion. The drilling device 7 is located on the upper surface of the base frame 1 and is used to open a reference hole in the side wall of the aluminum alloy bent part 9. The vibration damping device 8 is located on the upper surface of the base frame 1 and corresponds to the position of the reference hole.

[0035] It should be noted that, as a preferred embodiment, the support device 2 is connected to the upper surface of the base frame 1 by bolts, and the upper surface of the support device 2 is in contact with the lower surface of the aluminum alloy bent part 9. Multiple support devices 2 are provided, and their main function is to provide stable support for the aluminum alloy bent part 9 during the drilling process. When the drill bit drills into the aluminum alloy bent part 9, the support device 2 can effectively prevent the drill bit from vibrating, causing defects such as dullness or non-roundness on the hole surface, thereby ensuring the processing quality of the hole.

[0036] It should be noted that, as a preferred embodiment, such as Figure 1 and Figure 2 As shown, the vertical clamping device includes multiple vertical clamping mechanisms 3, which are evenly arranged along the aluminum alloy bent part 9. The evenly distributed clamping force effectively ensures the stability and processing accuracy of the aluminum alloy bent part 9 during drilling, and reduces deformation caused by uneven force.

[0037] More specifically, the vertical clamping mechanism 3 includes a horizontal clamp support 3-1 and a horizontal clamp 3-2. The horizontal clamp support 3-1 is connected to the upper surface of the base plate frame 1. More specifically, the horizontal clamp support 3-1 is fixed to the upper surface of the base plate frame 1 by screws and pins. The horizontal clamp 3-2 is located at the upper end of the horizontal clamp support 3-1. The horizontal clamp 3-2 includes a horizontal clamp linkage assembly 3-21 and a pressure head 3-22. The pressure head 3-22 is pressed down or lifted up by the horizontal clamp linkage assembly 3-21, which is convenient to operate and facilitates quick clamping and disassembly of the aluminum alloy bent part 9. When clamped, the pressure head 3-22 contacts the upper surface of the aluminum alloy bent part 9, which can effectively prevent the aluminum alloy bent part 9 from shifting during drilling and ensure the processing quality of the hole.

[0038] It should be noted that, as a preferred embodiment, such as Figure 1 and Figure 2 As shown, the side clamping device includes multiple side clamping mechanisms 4, which are evenly arranged along the aluminum alloy bent part 9. This evenly distributed design can effectively enhance the lateral stability of the aluminum alloy bent part 9 during the drilling process, ensuring that it is not prone to lateral displacement during processing, thereby improving processing accuracy.

[0039] More specifically, the side clamping mechanism 4 includes a vertical clamp support 4-1, a vertical clamp 4-2, and a side support 4-3. The vertical clamp support 4-1 is connected to the upper surface of the base plate frame 1. More specifically, the vertical clamp support 4-1 is fixed to the upper surface of the base plate frame 1 by screws and pins. The vertical clamp 4-2 is located at the upper end of the vertical clamp support 4-1. The vertical clamp 4-2 includes a vertical clamp linkage assembly 4-21 and a vertical clamp end 4-22. The vertical clamp end 4-22 moves forward or backward through the vertical clamp linkage assembly 4-21, making operation flexible and convenient, facilitating quick clamping and release of the aluminum alloy bent part 9. When the vertical clamp end 4-22 moves forward, it abuts against the outer surface of the side wall of the aluminum alloy bent part 9, effectively preventing lateral displacement of the aluminum alloy bent part 9 during drilling and ensuring the machining accuracy of the hole. The side support 4-3 is located on the other side of the aluminum alloy bent part 9 and corresponds to the position of the vertical clamp. The side support 4-3 and the vertical clamp 4-2 cooperate with each other to form a stable lateral support, which further enhances the stability of the aluminum alloy bent part 9 during drilling, reduces the risk of deformation of the aluminum alloy bent part 9 due to lateral force, and improves the processing quality.

[0040] It should be noted that, as a preferred embodiment, such as Figure 3 As shown, the planar inspection device 5 includes a first support platform 5-1, a first support 5-2, a first tilting arm 5-3, a first hinge shaft 5-4, a first inspection conformal block 5-5, a first baffle 5-6, and a first locking screw 5-7. The first support platform 5-1 is connected to the upper surface of the base frame 1. More specifically, the first support platform 5-1 is fixed to the upper surface of the base frame 1 by bolts. The first support 5-2 is located on the upper end of the first support platform 5-1. The height of the first support platform 5-1 is adjustable to adapt to inspection requirements at different heights. More specifically, the first support 5-2 is fixed to the upper end of the first support platform 5-1 by bolts. One end of the first tilting arm 5-3 is hinged to the first support 5-2 through the first hinge shaft 5-4. The first tilting arm 5-3 can be flexibly tilted, facilitating the loading and unloading of the tooling without damaging the aluminum alloy bent part 9. The other end of the first flipping arm 5-3 is provided with a first detection conforming block 5-5. The first detection conforming block 5-5 is fixed to the first flipping arm 5-3 by screws and pins. The first detection conforming block 5-5 fits against the flat part, and can accurately fit according to the shape of the flat part, improving the detection accuracy. The upper end of the first support 5-2 is also provided with a first baffle 5-6. The first baffle 5-6 is used to limit the flipping angle of the first flipping arm 5-3, prevent the first flipping arm 5-3 from flipping excessively, protect the flat detection device 5 from damage, and also prevent the first detection conforming block 5-5 from being bumped and damaged due to the first flipping arm 5-3 opening too large an angle. The first flipping arm 5-3 is provided with a first through hole, and the first support 5-2 is provided with a second through hole corresponding to the first through hole. Both the first through hole and the second through hole are provided with threads that cooperate with the first locking screw 5-7. The first locking screw 5-7 can pass through the first through hole and the second through hole to fix the position of the first flipping arm 5-3 and lock it firmly, which can ensure the stability of the position of the first detection conforming block 5-5 during the detection process and ensure the accuracy of the detection data.

[0041] It should be noted that, as a preferred embodiment, such as Figure 4As shown, the curved surface inspection device 6 includes a second support platform 6-1, a second support 6-2, a second flipping arm 6-3, a second hinge shaft 6-4, a second conforming inspection block 6-5, a second baffle 6-6, and a second locking screw 6-7.

One end of the second flipping arm 6-3 is hinged to the second support 6-2 via the second hinge shaft 6-4, allowing for flexible flipping and convenient loading and unloading of parts. The other end of the second flipping arm 6-3 is provided with a second conforming inspection block 6-5, which is fixed to the second flipping arm 6-3 by screws and pins. The second conforming inspection block 6-5 fits the curved surface portion precisely according to the curved shape of the curved surface portion, effectively ensuring the accuracy of the contour inspection of the curved surface portion. The upper end of the second support 6-2 is also provided with a second baffle 6-6. The second baffle 6-6 is used to limit the flipping angle of the second flipping arm 6-3, prevent excessive flipping, protect the safety of the device, and also prevent the second detection conformal block 6-5 from being damaged by excessive opening angle of the second flipping arm 6-3. The second flipping arm 6-3 is provided with a third through hole, and the second support 6-2 is provided with a fourth through hole corresponding to the third through hole. Both the third and fourth through holes are provided with threads that cooperate with the second locking screw 6-7.

The conformal support 7-1 is connected to the upper surface of the base frame 1, and the bottom connecting plate 7-2 is disposed on the conformal support 7-1. On the upper surface of the -1, the adjusting block 7-3 is set on the upper surface of the conformal support 7-1 and on the outside of the bottom connecting plate 7-2. In this embodiment, the bottom connecting plate 7-2 and the adjusting block 7-3 are fixed to the conformal support 7-1 with screws and pins, and a 3mm adjustment gap is left to be filled with shims. By increasing or decreasing the thickness of the shims, the axial position of the drill bit of the electric drill 7-9 is adjusted by three-coordinate detection, so that the theoretical deviation between the axial position of the drill bit and the axial position of the positioning process hole is controlled within ≤±0.05mm. The guide groove 7-4 is set on the upper surface of the bottom connecting plate 7-2. Two support slide plates 7-5 are installed on the bottom surface of the guide groove 7-4. The slider 7-6 is set in the guide groove 7-4. The upper ends of the slider 7-6 are blocked by the groove cover plate 7-7, so that the slider 7-6 can move back and forth along the guide groove 7-4. The groove cover plate 7-7 is connected to the guide groove 7-4. This design makes the movement of the slider 7-6 more stable and reliable. The upper end of the slider 7-6 is equipped with a connecting plate 7-8, and the upper end of the connecting plate 7-8 is equipped with a hand drill 7-9. The connecting plate 7-8 is also equipped with a drill chuck 7-10 and a fall arrestor hook 7-11. Both the drill chuck 7-10 and the fall arrestor hook 7-11 are used to fix the hand drill 7-9. This double fixing method ensures the stability of the hand drill 7-9 during drilling and prevents it from falling and causing damage or safety accidents. At the same time, the fall arrestor hook 7-11 can hold the hand drill 7-9 in place due to gravity when it is not in use, allowing the operator to free their hands for other operations. The stop block 7-12 is located at the front end of the guide slide 7-4. The stop block 7-12 is used to limit the maximum forward stroke of the hand drill 7-9, effectively preventing damage to the equipment caused by excessive forward movement of the hand drill 7-9, and also preventing drilling too deep and penetrating the cavity of the aluminum alloy bent part 9. The guide sleeve support 7-13 is connected to the upper surface of the base plate frame 1 and is fixed to the base plate frame 1 with screws and pins. The guide sleeve 7-14 is connected to the guide sleeve support 7-13 through the guide sleeve adjusting block 7-15. The guide sleeve 7-14 is provided with a guide hole. The guide sleeve adjusting block 7-15 is fixed to the guide sleeve support 7-13 with screws and pins. The guide sleeve 7-14 is axially adjusted by adding or removing shims between the guide sleeve adjusting blocks 7-15 so that the position of the guide hole of the guide sleeve 7-14 is adjusted to within ±0.1mm relative to the gauge reference. The guide sleeve 7-14 can be fitted into the guide sleeve adjusting block 7-15 and fastened with screws.The guide hole is set at the reference hole position of the aluminum alloy bent part 9. After the drill bit of the electric drill 7-9 passes through the guide hole, the reference hole is opened on the side wall of the aluminum alloy bent part 9. The guide sleeve 7-14 can guide the drill bit of the electric drill 7-9 to accurately align with the drilling position, thereby improving the drilling accuracy. The guide sleeve adjustment block 7-15 can finely adjust the position of the guide sleeve 7-14 to adapt to aluminum alloy bent parts 9 of different sizes, thereby enhancing the versatility of the device.

The lower end of the supporting rotating arm 8-2 is connected to the locking support 8-1 through the hinge shaft 8-3, and the upper end of the supporting rotating arm 8-2 is provided with a through hole. The through hole has an internal thread that mates with the bolt connecting rod 8-4. The bolt connecting rod 8-4 passes through the through hole, and the support stroke can be adjusted by the protruding length of the bolt connecting rod 8-4. A top block 8-5 is provided at the end of the bolt connecting rod 8-4 near the aluminum alloy bent part 9. The top block 8-5 is connected to the bolt connecting rod 8-4 by a fixing nut 8-6. The top block 8-5 can tightly fit the surface of the aluminum alloy bent part 9, effectively transmitting and dispersing vibrations generated during drilling and protecting the surface of the aluminum alloy bent part 9. The locking rod mounting block 8-7 is connected to the locking support 8-1. The locking rod mounting block 8-7 has a locking rod through hole with an internal thread that mates with the locking rod 8-8. After passing through the locking rod through hole, the locking rod 8-8 abuts against the side wall of the supporting rotating arm 8-2. The locking rod 8-8 is used to fix the position of the supporting rotating arm 8-2, ensuring that the supporting rotating arm 8-2 remains stable during drilling, further enhancing the anti-vibration effect and improving drilling accuracy and quality.

[0044] In use, the vertical clamping mechanism 3, the flat surface detection device 5, and the curved surface detection device are first opened. The aluminum alloy bent part 9 is placed on the inspection fixture, with the outer arc of the aluminum alloy bent part 9 aligned with the side support 4-3 and the bottom attached to the support device 2. The first flipping arm 5-3 of the flat surface detection device 5 is flipped down and locked with the first locking screw 5-7. The second flipping arm 6-3 of the curved surface detection device 6 is flipped down and locked with the second locking screw 6-7. Then, the go / no-go gauge is used to check the contour of the inner and outer arc surfaces of the aluminum alloy bent part 9 from left to right. After the contour of each major requirement point is qualified, the side clamping mechanism 4 is used to clamp the workpiece, and the locking rod 8-8 on the anti-vibration mechanism 8 is tightened to make the top block 8-5 fit against the surface of the aluminum alloy bent part 9. Handle the electric drill 7-9, open the anti-fall hook 7-11, push the electric drill 7-9 forward to drill a small diameter reference hole. After the hole is opened, open the first locking screw 5-7 and the second locking screw 6-7, flip the first flip arm 5-3 and the second flip arm 6-3 upward, open the locking rod 8-8 and the side clamping mechanism 4, and remove the aluminum alloy bent part 9.

[0045] The drilled reference holes are then used as positioning pins for positioning. The reference holes on the opposite surface are then machined, and the reference holes are used for positioning. Positioning process holes and other machining features on this surface are then machined. The position of the process positioning hole is selected from the larger hole that needs to be machined on the product. For example, if a Φ10mm hole is selected on the product, the size of the process positioning hole is set to a value smaller than its diameter, such as Φ6mm. Therefore, the process positioning hole will be expanded and covered after subsequent machining, and no extra process positioning hole will remain. This solves the problem of inconsistent relative reference between the curved surface of the bent profile and the subsequent hole position machining. Compared with the previous method of aligning the scribing reference by visual inspection, the product qualification rate has increased from 60% to 100%. At the same time, it avoids human error caused by visual alignment and ensures the consistency of the product processing production reference.
