Description

Technical Field

[0001] The present invention relates to the technical field of automobile assembly, in particular to a vehicle body circulation tooling. Background Art

[0002] In recent years, my country's overseas passenger vehicle exports have been increasing, with a significant portion being shipped using the SKD and DKD methods. These methods typically leave the vehicles without axles or tires, making their temporary outdoor operation more challenging. Common methods include using a wheeled crane to lift the vehicles onto a pallet truck for transportation, or using two forklifts to forklift the vehicles onto a flatbed truck for transportation.

[0003] The main problems with the above-mentioned vehicle turnover are: (1) Lifting with a wheeled crane is a special operation, which requires the entire vehicle to be lifted more than one meter high. This has high risks and low efficiency. (2) Two forklifts are used to lift the bottom frame of the vehicle, one in front and one behind. If the two forklifts do not cooperate well, they will be out of sync during the lifting process, which will cause the vehicle body to fall and the efficiency will be low. Summary of the Invention

DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0024] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0027] Example 1 like Figure 1-Figure 7 As shown, the vehicle body transfer tooling provided by the present invention includes: a front axle connection, a rear axle connection, a forklift, a trailer trough 31, and a locking pin 33. The front axle connection and rear axle connection are provided in multiple sets, with one front axle connection and one rear axle connection mounted on a vehicle frame (not shown). The forklift, trailer trough 31, and locking pin 33 are assembled together, and the number of each can be one.

[0028] like Figure 1-Figure 3 As shown, both the front and rear axle connection parts include a frame 1 and a deformable turntable. Depending on the front-to-back position of the vehicle body, the shapes of the front and rear axle connection parts' frames 1 can be different or identical. Both the front and rear axle connection parts' frames 1 support and connect the deformable turntables. In this embodiment, the front axle connection part's frame 1 and the deformable turntable are used as examples for illustration. The deformable turntable of the rear axle connection part has the same posture as the front axle connection part's deformable turntable.

[0029] The frame 1 of the front axle connection part is provided with a first connection part connected to the front axle connection position of the vehicle frame, and the frame 1 of the rear axle connection part is provided with a second connection part connected to the rear axle connection position of the vehicle frame.

[0030] like Figure 3 As shown, the frame 1 can be a rectangular frame 1 extending in the left-right direction. The frame 1 can be formed by welding square steel and has a strong structure. The first connecting part and the second connecting part can both include a connecting plate 7. The number of connecting plates 7 on the first connecting part and the second connecting part can be four, arranged at the four corners of a rectangle. The frame 1 has four first waist holes 51 distributed in a rectangular shape, and the length direction of the first waist hole 51 is the left-right direction, while the length direction of the second waist hole 52 on the connecting plate 7 is the front-back direction. During assembly, the connecting plate 7 is first connected to the frame, and then the frame 1 is lifted up to align the first waist hole 51 and the second waist hole 52, and then the connecting plate 7 and the frame 1 are locked with bolts and nuts. By setting the length directions of the first waist hole 51 and the second waist hole 52 vertically, the difficulty of installation can be reduced. When there is a slight misalignment in the connection between the connecting plate 7 and the frame, the first waist hole 51 and the second waist hole 52 can also be aligned by adjusting the left and right positions of the frame 1.

[0031] The connecting plate 7 can be welded to the frame. After the transportation is completed, the frame 1 can be recycled, but the connecting plate 7 does not need to be recycled. In other possible implementations, in order to improve the installation accuracy, a first docking hole for docking with the connecting plate 7 can be provided on the frame, and a second docking hole can be provided on the connecting plate 7. By aligning the first docking hole with the second docking hole and then connecting them with bolts and nuts, the positioning installation of the connecting plate 7 can be achieved.

[0032] like Figure 2 As shown, a deformation turntable is rotatably connected to the left and right sides of a frame 1. The deformation turntable includes a cross 2, which includes a first straight arm 61, a second straight arm 62, a third straight arm 63 and a fourth straight arm, and any two adjacent arms form a 90° angle.

[0033] The cross 2 includes a first end 21, a second end 22, a third end 23 and a fourth end 24 arranged in sequence along the circumferential direction (respectively located on the first straight arm 61, the second straight arm 62, the third straight arm 63 and the fourth straight arm).

[0034] The deformation turntable can rotate relative to the frame 1 to a first posture and a second posture and maintain them.

[0035] like Figure 2 As shown, in the first posture, the fourth end 24 faces downward, the first end 21 and the third end 23 face forward and backward respectively, and the second end 22 faces upward.

[0036] like Figure 4 As shown (the second layer of the stack), in the second posture, the fourth end 24 faces forward, the first end 21 and the third end 23 face upward and downward respectively, and the second end 22 faces backward.

[0037] The first end 21 is provided with a first docking structure 41; the second end 22 is provided with a second docking structure 42; the third end 23 is provided with a third docking structure 43; and the fourth end 24 is connected to a roller 25. The third docking structure 43 of one frame 1 can be connected to the first docking structure 41 of another frame 1, and the third docking structure 43 of one frame 1 can be connected to the second docking structure 42 of another frame 1.

[0038] A frame is combined with a front axle connection part and a rear axle connection part to form a transfer part. When the cross 2 is in the first posture, the roller 25 of the transfer part is in contact with the ground, and the transfer part can be transferred under the towing of a forklift. Specifically, the fork arm of the forklift is combined, and the rotating shaft 32 is connected to the mounting hole and locked by the locking pin 33; prevent the trailer trough 31 from falling off. Drive the forklift to the front end of the frame, align the trough with the front main beam of the frame, and slowly lift the fork arm until the trough is stuck in the main beam 6. Start the forklift and transfer the frame to the storage area.

[0039] like Figure 4 As shown, a forklift is used to transport the first transfer unit to the ground in the storage area. At this time, the cross 2 of the first transfer unit can be maintained in the first posture or adjusted to the second posture. A crane can be used for stacking. After the stacking is completed (for example, three or four transfer units are stacked), if transfer is required, the stacked frames can be pushed into the container together (the rollers 25 can be locked) to complete the packaging. If the frames are only stored for a long time, the cross 2 of the lowest transfer unit can be adjusted to the second posture, with the third end 23 or the first end 21 of the cross 2 touching the ground. This can prevent the rollers 25 of the lowest transfer unit from being subjected to excessive pressure, resulting in deformation and reduced service life.

[0040] Except for the bottom layer, the crosses 2 of the transfer pieces on other layers can be in the second posture, and the second docking structure 42 of the cross 2 of the transfer piece on the bottom layer is connected to the third docking structure 43 of the cross 2 of the transfer piece on the next lower layer; except for the transfer pieces on the bottom layer, in the transfer pieces on other two adjacent layers, the first docking structure 41 of the transfer piece located below is connected to the third docking structure 43 of the transfer piece located above.

[0041] The entire frame transfer process is as follows: In the first step, the vehicle frame is suspended, and the front axle connection part is lifted by a forklift and transferred to the bottom of the front axle connection position of the vehicle frame, and then the front axle connection part is connected to the vehicle frame; similarly, the rear axle connection part is connected to the vehicle frame to form a transfer part; and the cross 2 of the front axle connection part and the rear axle connection part are both in the first posture; The second step is to place the frame on the ground; The third step, such as Figure 3 and Figure 7 As shown, assemble the forklift's fork arms, connect the shaft 32 to the mounting hole, and lock it with the locking pin 33 to prevent the trailer trough 31 from falling off. Drive the forklift to the front of the frame, align the trough with the front main beam of the frame, and slowly lift the fork arms until the trough engages the main beam 6. Start the forklift and move the frame to the storage area. Step 4: Use a forklift to transport the first transfer unit to the ground in the storage area. At this time, the cross 2 of the first transfer unit can be maintained in the first posture or adjusted to the second posture. The fifth step is to use a forklift to transport the second transfer part to the storage area and arrange it above the first transfer part, and connect the crosses 2 of the two transfer parts together up and down, and repeat the above transfer and stacking process until stacking is no longer possible.

[0042] The above-mentioned vehicle body transfer tooling can realize the short-distance transfer and stacking of vehicle frames. The stacking stability is strong during storage, and the problem of tipping will not occur even when the stacked state is transported. In addition, the front and rear axle connecting parts can be reused after being disassembled.

[0043] The first docking structure 41 includes a first lug plate disposed on the sidewall of the first end 21, with a first through-hole disposed on the first lug plate. The second docking structure 42 includes a second lug plate disposed on the sidewall of the second end 22, with a second through-hole disposed on the second lug plate. The third docking structure 43 includes a third lug plate disposed on the sidewall of the first end 21, with a third through-hole disposed on the third lug plate. The distribution structure of the third through-holes on the third lug plate is identical to the distribution structure of the second through-holes on the second lug plate and the distribution structure of the first through-holes on the first lug plate, respectively, so that the first, second, and third lug plates are connected via bolts and nuts.

[0044] The frame 1 has a crossbeam 6 extending in the front-to-back direction, with multiple crossbeams 6 extending in the left-to-right direction. To connect the frame 1 to the connecting plate 7, the forklift's fork arm is inserted into the frame 1 from either the left or right side. The fork arm then contacts and lifts the crossbeam 6, pushing the frame 1 toward the vehicle frame. The multiple crossbeams 6 ensure sufficient contact with the fork arm, preventing the frame 1 from tilting in the left-to-right direction relative to the fork arm.

[0045] In the front-to-back direction, the center of the crossbeam 6 is offset from the axis of the cross 2, so that the cross 2 avoids the fork arm, and the fork arm can be lifted in the middle position of the crossbeam 6 to prevent the frame 1 from tilting in the front-to-back direction.

[0046] A limiting structure is provided between the cross 2 and the frame 1. When the limiting structure is locked, the cross 2 is fixed relative to the frame 1. Specifically, each straight arm of the cross 2 is provided with a first limiting hole (not shown), and the frame 1 is provided with a second limiting hole. The front axle connection portion and the rear axle connection portion each include two first locating pins. Assuming that when the cross 2 is in a first posture, the first limiting hole on the first straight arm 61 is aligned with the second limiting hole, the first locating pin is used to pass through one of the first limiting hole and the second limiting hole, respectively, to fix the cross 2 relative to the frame 1. Each time the posture of the cross 2 is adjusted, the locking pin 33 needs to be pulled out.

[0047] Example 2 like Figure 5 and Figure 6 As shown, the first docking structure 41 includes a first ear plate arranged on the side wall of the end portion of the first end 21, and a first through hole is provided on the first ear plate; the second docking structure 42 includes a second ear plate arranged on the side wall of the end portion of the second end 22, and a second through hole is provided on the second ear plate; the third docking structure 43 includes a third ear plate arranged on the side wall of the end portion of the first end 21, and a third through hole is provided on the third ear plate.

[0048] The difference from the first embodiment is that, in this embodiment, the first straight arm 61 and the third straight arm 63 are different, and the first straight arm 61 is thicker than the third straight arm 63 .

[0049] like Figure 5 As shown (the second stacked layer), the deformation turntable can be rotated to a third posture relative to the frame 1, in which the fourth end 24 faces rearward, the first end 21 and the third end 23 face downward and upward respectively, and the second end 22 faces forward.

[0050] like Figure 6 As shown, the third straight arm 63 forming the third end 23 in the cross 2 is thinner than the first straight arm 61 forming the first end 21 in the cross 2, and a socket 64 is provided at the end of the first straight arm 61. The third straight arm 63 can be inserted into the socket 64 of the first straight arm 61 along the length direction of the first straight arm 61, so that two adjacent transfer parts can be deformed into two different combination forms, thereby adapting to frames of different heights.

[0051] like Figure 5As shown, in the first combination configuration, one of the crosses 2 of two adjacent transfer units is in the second position and the other in the third position, so that the first docking structure 41 of one transfer unit is connected to the first docking structure 41 of the other transfer unit, or the third docking structure 43 of one transfer unit is connected to the third docking structure 43 of the other transfer unit, so that the height of the vertical accommodation gap formed between the two adjacent transfer units after stacking is h1. In this case, h1 is larger, and the gap between the upper and lower adjacent frames 1 is larger, which can accommodate taller frames (such as frames with roof shells).

[0052] like Figure 6 As shown, in the second combination configuration, the crosses 2 of two adjacent transport units are both in the second or third position, with the third straight arm 63 of one transport unit inserted into the first straight arm 61 of the other transport unit. This allows the vertical accommodation gap between the two stacked transport units to have a height of h2, which is smaller than h1. In this case, h2 is smaller, and the gap between the upper and lower adjacent frames 1 is smaller, allowing for a lower frame (e.g., a frame with only a chassis). This combination configuration allows for a greater number of stacked transport units, fully utilizing the vertical space.

[0053] The user can adjust the posture of the cross 2 according to production needs, thereby forming different states to transport different types of frames.

[0054] In order to further improve the connection strength, a fourth ear plate 44 is provided on the side wall of the third straight arm 63, and the fourth ear plate 44 is spaced apart from the third ear plate; a fourth through hole is provided on the fourth ear plate 44, and the distribution structure of the fourth through hole is consistent with the distribution form of the first through hole on the first ear plate. When the first straight arm 61 and the third straight arm 63 are plugged in, the third through hole and the fourth through hole are aligned, and the two are locked with bolts and nuts to prevent the upper and lower crosses 2 from shaking.

[0055] The end surface of the first end 21 of the first straight arm 61 is provided with a socket 64 for inserting the third straight arm 63.
