Description

Technical Field

[0001] This invention relates to the field of automobile body manufacturing, and more specifically, to a device and method for transferring and transporting inner side panels of an automobile body. Background Technology

[0002] In automobile body manufacturing, the transfer of the inner side panel is a key process. The traditional solution uses fixed mechanical fixtures in conjunction with manual operation. When faced with the diversification of vehicle models, there are problems such as difficulty in adjusting the support, low accuracy of the lifting mechanism, and lag in the positioning of the lifting device, which cannot meet the needs of automated production. The existing technology uses a base plate to install a fixed support, uses a lifting frame for initial positioning, manually controls the positioning pin cylinder to complete the workpiece fixation, and then uses a lifting device for transfer. Its structure includes a base plate, support, lifting frame and distributed operation control, which has the following disadvantages: (1) Large positioning deviation: the fixed support cannot adapt to different workpiece sizes, and the leveling accuracy of the lifting frame is insufficient, resulting in positioning errors exceeding the process requirements; (2) Low operation efficiency: the distributed knobs need to be operated multiple times, and the adjustment of the lifting device position depends on manual measurement, which takes a long time; (3) Insufficient compatibility: a large number of support components need to be replaced for different vehicle models, which is costly and time-consuming; (4) Interference risk: the design of the platform and cylinder positions is unreasonable, and mechanical interference is likely to occur during operation.

[0003] It is evident that existing automotive body side panel transfer equipment suffers from problems such as insufficient positioning accuracy, cumbersome operation, and poor equipment compatibility, resulting in low transfer efficiency and easy damage to workpieces. There is an urgent need to improve transfer stability and automation adaptability through structural optimization. Summary of the Invention

[0067] Example 1

[0068] like Figure 1 As shown, this embodiment provides a vehicle body side panel transfer device. This device, through the coordinated combination of a multi-layered combined support structure, a precision leveling and height adjustment mechanism, an integrated control operating system, an anti-interference spatial layout, and adaptable lifting device components, achieves rapid positioning, high-precision transfer, and stable transport of workpieces from multiple vehicle models and batches, significantly improving production efficiency and automation levels. The overall structure of the device consists of modules such as a base plate 1, a height-adding platform 2, a lifting frame 3, and a support system, which work together collaboratively.

[0069] like Figure 2 As shown, the device adopts a structural layout with a base plate 1 as the supporting platform. The base plate 1 is preferably 20mm thick and is made of carbon steel or aluminum alloy, providing high flatness and strength. Multiple M10 threaded holes and φ10mm pin holes are evenly distributed on the surface of the base plate 1, with a standard hole spacing of 200mm laterally and 150mm longitudinally. These holes are used for precise positioning and assembly with components such as the elevation platform 2, lifting frame 3, and platform 5. A φ22mm through hole is opened at the edge of the base plate 1 for inserting connecting rods to achieve rigid connection of multiple modules. The surface levelness tolerance of the entire base plate 1 is ≤0.5mm. The base plate 1 also includes several positioning pin cylinders 11. Each positioning pin cylinder 11 includes a cylinder structure and a positioning pin rod, where the positioning pin rod is used to insert into or retract from the workpiece positioning hole to achieve workpiece positioning and release.

[0070] like Figure 3As shown, several raised platforms 2 are installed on the base plate 1 as intermediate adjustment layers, preferably 120mm high, to raise the mounting surface of the supports and adapt to the bottom contours of different vehicle models. They are connected to the base plate 1 by four sets of M12 bolts. Figure 4 As shown, a positioning block 21 is provided on its side to prevent displacement. By setting a heightening platform 2 on the base plate 1, the mounting surface of the support can be raised by 120mm, allowing the support to be further finely adjusted in height by adding or removing shims (thickness 1-5mm) to adapt to the bottom contour of different workpieces. The top of the heightening platform 2 is provided with multiple sets of support mounting holes, which can be combined with supports and shims of different heights for adjustment.

[0071] like Figure 5 As shown, a lifting frame 3 is also installed on the base plate 1. The lifting frame 3 is positioned on the base plate 1 via a pin structure and, together with the heightening platform 2, forms the core of the overall support. The lifting frame 3 includes a frame assembly 31 and lifting mechanisms 32 on both sides. The lifting mechanisms 32 are equipped with precision M16 leveling bolts, allowing for fine-tuning of the overall height of the support with an adjustment accuracy within ±0.1mm. A 20mm thick support block is welded to the reverse side of the frame assembly 31 to enhance stability. During operation, the lifting stroke of the lifting frame 3 is controlled within ±0.3mm. During installation, initial positioning is achieved by using the pin structure on the frame assembly 31 to engage with the base plate 1, followed by tightening with anchor bolts (pin diameter 10mm, depth 30mm). Then, leveling is performed using the M16 leveling bolts on the lifting mechanisms 32 on both sides. After leveling, the support is secured with anchor bolts (torque 80-100 N·m).

[0072] like Figure 6 As shown, a support system is also provided on the base plate 1 for contacting and positioning the inner side panel of the vehicle body. The support system mainly includes an adjustable support 41 and a directly replaceable standard support 42. The adjustable support 41 is provided with a support block 44 for supporting the workpiece, and the standard support 42 is provided with a positioning boss with a height of 10mm and a diameter of 30mm for positioning the lifting device. The height and angle of the above support system can be finely adjusted by shims or adjusting bolts to adapt to different vehicle models or modified parts. Multiple sets of supports can form a support network through connecting blocks 43 to achieve surface contact positioning and control the flatness of the workpiece, with a positioning accuracy of ≤0.2mm.

[0073] This device also includes an operation control unit, the core of which is a three-position five-way rotary switch. This switch controls the three states of the positioning pin cylinder 11: "extend," "neutral," and "retract," completing the pin positioning and release of the workpiece. The positioning pin cylinder 11 is mounted on the base plate 1. During operation, the positioning pin of the cylinder 11 can be inserted into the process hole in the inner panel of the vehicle body side panel for limiting, improving positioning accuracy before transfer. During release, the positioning pin retracts, allowing the lifting device to smoothly grasp the workpiece. The knob is equipped with a mechanical transmission rod connected to the positioning pin cylinder 11, providing a 1:1 action ratio for intuitive response and preventing accidental operation. This structure transforms the operation process from multiple controls into one-button control, resulting in more precise cycle control.

[0074] like Figure 7 As shown, to prevent spatial interference between the lifting device, cylinder, and operator's operating platform, this device also includes an anti-interference structure, including a platform 5 structure. The platform 5 structure is located in the front operating area of ​​the device, facilitating operator access to the support and lifting device. A positioning pin cylinder 11 is located below the platform 5 structure. The platform 5 structure has an avoidance hole 51, the diameter of which is slightly larger than the outer diameter of the cylinder, ensuring that the positioning pin cylinder 11 does not collide with the platform 5 during extension and retraction. Simultaneously, the platform legs are connected to the base plate 1 by large-pitch bolts to maintain rigidity and prevent lateral compression.

[0075] Optional, such as Figure 8 As shown, to meet the requirements for transferring large-sized side panels as a whole, multiple base plates 1 can be fastened together to form an integral platform, thereby enhancing the overall rigidity of the system. The connecting device includes connecting rods 6 and fastening nuts. Each connecting rod 6 has a diameter of 20mm and a length of 1200mm based on the platform width. Each base plate 1 has a pre-drilled φ22mm connecting hole through which the connecting rod 6 passes. Both ends are locked with M20 nuts, and anti-loosening washers are placed between the nuts and the base plate 1.

[0076] At the same time, such as Figure 9 As shown, the device also includes a lifting device adapter structure, which includes a sensor bracket 72 and an additional support 73, for achieving precise docking between the lifting device and the inner side panel. The sensor bracket is a cantilever structure with a length of 200mm, and a photoelectric sensor is mounted on it. The detection distance of the photoelectric sensor is 0 to 500mm.

[0077] Example 2

[0079] 1. Place the base plate 1 in the transfer station area;

[0080] 2. Install the elevation platform 2 on the base plate 1 and set the initial height;

[0081] 3. Insert the jacking frame pin 3, level it with the leveling bolts, and then tighten it with the anchor bolts;

[0082] 4. Install adjustable or standard supports, and form a workpiece support surface through connecting blocks and support blocks;
