[0056] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0058] During the assembly process of the vehicle, the chassis and the front and rear subframes need to be assembled into a body structure. In the related art, the method of assembling the body structure of the vehicle is mainly to lift the chassis through a two-column lifting mechanism, and use a lifting vehicle to lift the front and rear subframes on the front and rear sides of the chassis respectively, so that the front and rear subframes can be welded and assembled on the chassis to achieve assembly. However, when the chassis is lifted by a two-column lifting mechanism, the stability of the chassis is poor; during the process of welding and assembling the chassis with the front and rear subframes, the chassis may be tilted due to force, which will affect the assembly operation.

[0059] Based on the above considerations, in order to solve the problem of poor stability of the chassis when the two-column lifting mechanism is used to lift the chassis in the related art, a splicing device for vehicle chassis assembly is designed. By arranging a plurality of locking devices on the working end face of the tooling table, the plurality of locking devices can be arranged in a row along the first direction to form two rows of locking groups, and a locking area is formed on the working end face between the two rows of locking groups distributed in the second direction; thus, the chassis to be assembled can be placed in the locking area, and the locking devices at the opposite ends of the chassis in the second direction are used to press and lock the chassis, thereby effectively improving the stability of the chassis locked on the working end face of the tooling table, and further reducing the probability of the chassis warping during the assembly process.

[0060] Next, a splicing device for vehicle chassis assembly provided by an embodiment of the present application will be described in detail.

[0061] Please refer to Figure 1 and Figure 2 As shown in FIGS. and, an embodiment of the present application provides a splicing device 1000 for vehicle chassis assembly, including a tooling table 100 and a plurality of locking devices 200; the tooling table 100 has a working end face 110, and the plurality of locking devices 200 are arranged on the working end face 110; the plurality of locking devices 200 are arranged in sequence along the first direction X to form two rows of locking groups 201, the two rows of locking groups 201 are spaced apart along the second direction Y, and a locking area 111 is formed on the working end face 110 between the two rows of locking groups 201; wherein, the first direction X and the second direction Y are arranged at an angle.

[0062] Among them, the tooling table 100 refers to a workbench or a combination of workbenches in an industrial or working place, which is used for support to realize operations such as assembly and welding. It should be understood that the tooling table 100 can be a fixed structure, and the tooling table 100 can provide a stable support environment.

[0063] The tooling table 100 has a working end face 110; the working end face 110 refers to the end face on one side of the tooling table 100 for realizing the support function.

[0064] The locking device 200 is used to realize the locking function, so that the structure to be assembled (such as the chassis, etc.) placed on the working end face 110 can be locked by the locking device 200. Optionally, the locking device 200 can be locked by pressing, that is, the structure to be assembled (such as the chassis, etc.) is tightly pressed on the working end face 110 to realize locking; or, the locking device 200 can also be locked by clamping and fixing.

[0065] The locking device 200 can be fixedly installed on the working end face 110. Exemplarily, it can be fixed to the working end face 110 by means of welding, fastener connection, etc.; or, the locking device 200 can be adjusted to install at the installation position on the working end face 110. Exemplarily, it can be realized by a slotted hole for adjustable assembly, etc.; or, the locking device 200 can also be installed on the working end face 110 through other structures (such as mounting plates, mounting brackets, etc.).

[0066] The number of the locking devices 200 is multiple, for example, it can be any number such as two, three or more than three.

[0067] The locking group 201 refers to an assembly formed by two or more locking devices 200 arranged in sequence or at intervals along the first direction X. There are two rows of the locking groups 201, and the two rows of the locking groups 201 are spaced apart along the second direction Y; thus, the two rows of the locking groups 201 can be distributed on the opposite sides of the structure to be assembled and lock the structure to be assembled.

[0068] Wherein, the first direction X can be any direction parallel to the working end face 110. For example, it can be parallel to the length direction of the working end face 110, or it can be parallel to the width direction of the working end face 110, etc. Similarly, the second direction Y can be any direction parallel to the working end face 110. For example, it can be parallel to the length direction of the working end face 110, or it can be parallel to the width direction of the working end face 110, etc.

[0069] The first direction X and the second direction Y are arranged at an angle. Exemplarily, the first direction X can be perpendicular to the second direction Y. In some embodiments, the working end face 110 can be a rectangular face, the first direction X can be parallel to the length direction of the working end face 110, and the second direction Y can be parallel to the width direction of the working end face 110; thus, the locking devices in the locking group 201 are arranged in sequence along the length direction of the working end face 110, and the two rows of the locking groups 201 are spaced apart along the width direction of the working end face 110.

[0070] The locking area part 111 refers to the part of the working end face 110 between the two rows of the locking groups 201; the locking area part 111 is used for accommodating the structure to be assembled. Thus, the two rows of the locking groups 201 can be respectively located on the opposite sides of the structure to be assembled in the second direction Y and lock the structure to be assembled on both sides.

[0071] The assembling device 1000 for vehicle chassis assembly provided by the embodiment of the present application can use the working end face 110 of the tooling table 100 to place the structure to be assembled (such as the chassis), and use a plurality of locking devices 200 arranged on the working end face 110 to press and lock the structure to be assembled; the locking devices 200 are arranged in two rows of locking groups 201 along the first direction X, and the working end face 110 between the two rows of locking groups 201 forms a locking area part 111. Thus, the structure to be assembled can be placed in the locking area, and the locking devices 200 in the locking groups 201 at the opposite ends of the structure to be assembled in the second direction Y can lock the structure to be assembled, effectively improving the stability of the structure to be assembled locked on the working end face 110 of the tooling table 100, and further reducing the probability of warping of the structure to be assembled during the assembly process.

[0072] Please refer to Figure 2 , in some embodiments, the locking device 200 is configured to be able to adjust its own installation position in the second direction Y.

[0073] In this embodiment, the locking device 200 can adjust its installation position in the second direction Y; thus, the distance between the two rows of locking groups 201 arranged at intervals in the second direction Y is adjustable.

[0074] Optionally, in some implementation manners, the installation position of the locking device 200 in the second direction Y can be realized by arranging waist-shaped holes on the working end face 110; by setting the length direction of the waist-shaped holes along the second direction Y, thus, during assembly, the specific installation position of the locking device 200 can be adjusted adaptively according to the length of the waist-shaped holes.

[0075] Or, in other implementation manners, the installation position of the locking device 200 in the second direction Y can be realized by arranging multiple rows of installation holes on the working end face 110; by arranging the multiple rows of installation holes at intervals along the second direction Y, during assembly, the locking device 200 can be installed in different rows of installation holes to realize the adjustment of the installation position.

[0076] Or, in other implementation manners, the installation position of the locking device 200 relative to the working end face 110 in the second direction Y can also be positioned and adjusted by means of pins, lock holes, etc.

[0077] With such a setting, the locking device 200 can adjust its installation position along the second direction Y, thus, the distance between the two rows of locking groups 201 formed in the second direction Y is adjustable, that is, the size of the locking area part 111 is adjustable, so as to meet the locking prevention of more size models of the structure to be assembled, and improve the application range of the assembling device 1000 for vehicle chassis assembly.

[0078] Please refer toFigure 2 and Figure 4 , in some embodiments, a first mounting structure 120 is provided on the working end face 110, and the locking device 200 is disposed on the working end face 110 through the first mounting structure 120; the first mounting structure 120 is configured to be able to adjust the mounting position of the locking device 200 in the second direction Y.

[0079] Among them, the first mounting structure 120 includes, but is not limited to, structures such as oblong holes, multi-row holes, etc. opened on the working end face 110.

[0080] When the first mounting structure 120 includes an oblong hole opened on the working end face 110, the length direction of the oblong hole is arranged along the second direction Y; the locking device 200 can be fixedly assembled on the working end face 110 by passing a fastener (such as a bolt, a screw, etc.) through the oblong hole.

[0081] When it is necessary to adjust the locking device 200 to reduce the size of the locking area portion 111 to be applicable to a smaller-sized structure to be assembled, the fastener can be loosened, and at least one row of the two rows of locking groups 201 distributed in the second direction Y can be moved and adjusted in the opposite direction, and after adjusting to the preset position, the fastener can be tightened to realize the adjustment and fixed assembly of the mounting position of the locking device 200 in the locking group 201.

[0082] When it is necessary to adjust the locking device 200 to increase the size of the locking area portion 111 to be applicable to a larger-sized structure to be assembled, the fastener can be loosened, and at least one row of the two rows of locking groups 201 distributed in the second direction Y can be moved and adjusted in the opposite direction, and after adjusting to the preset position, the fastener can be tightened to realize the adjustment and fixed assembly of the mounting position of the locking device 200 in the locking group 201.

[0083] When the first mounting structure 120 includes multi-row holes (such as two rows, three rows or more of mounting holes spaced along the second direction Y) opened on the working end face 110, the locking device 200 can be fixedly assembled on the working end face 110 by passing a fastener (such as a bolt, a screw, etc.) through one row of the multi-row holes.

[0084] When it is necessary to adjust the locking device 200 to reduce the size of the locking area portion 111 to be applicable to a smaller-sized structure to be assembled, the fastener can be removed, and at least one row of the two rows of locking groups 201 distributed in the second direction Y can be moved towards the other row of the locking group 201 to the next row or multiple rows of mounting holes, and the fastener can be used to pass through the mounting holes for fixed assembly to realize the adjustment and fixed assembly of the mounting position of the locking device 200 in the locking group 201.

[0085] When it is necessary to adjust the locking device 200 to enlarge the size of the locking area 111 to be applicable to a larger-sized structure to be assembled, the fastener can be disassembled, and at least one row of the two rows of locking groups 201 distributed in the second direction Y is moved away from the other row of locking groups 201 to the installation holes of the next row or multiple rows, and the fastener is passed through the installation holes for fixed assembly, so as to realize the adjustment of the installation position of the locking device 200 in the locking group 201 and fixed assembly.

[0086] With such a setting, the locking device 200 is assembled on the working end face 110 by using the first installation structure 120, so that the locking device 200 can adjust its installation position in the second direction Y, thereby having a larger applicable range.

[0087] Please refer to Figure 2 、 Figure 4 and Figure 5 , in some embodiments, the splicing device 1000 for vehicle chassis splicing further includes a connecting piece 300, and the locking device 200 in at least one row of locking groups 201 is arranged on the corresponding connecting piece 300; the connecting piece 300 is connected to the working end face 110 through the first installation structure 120; the first installation structure 120 is configured to be able to adjust the installation position of the connecting piece 300 in the second direction Y.

[0088] The connecting piece 300 is used to assemble one row of the locking groups 201, so that this row of locking groups 201 can be assembled on the working end face 110 through the connecting piece 300.

[0089] Optionally, one row of the two rows of locking groups 201 can be assembled on the working end face 110 through the connecting piece 300, and the locking devices 200 in the other row of locking groups 201 are directly assembled on the working end face 110; or, the two rows of locking groups 201 are assembled on the working end face 110 through two connecting pieces 300, that is, each row of locking groups 201 is respectively assembled through a corresponding connecting piece 300.

[0090] Among them, the connecting piece 300 can be but is not limited to a connecting plate, a connecting block, a connecting bracket, etc. The connecting piece 300 is connected to the working end face 110 through the first installation structure 120. Thus, the connecting piece 300 can adjust its assembly position relative to the working end face 110 in the second direction Y, and further, all the locking devices 200 in the locking group 201 assembled on the connecting piece 300 can be synchronously adjusted to improve the adjustment efficiency.

[0091] The first mounting structure 120 includes, but is not limited to, structures such as oblong holes and multi-row holes formed on the working end face 110. It should be understood that when the first mounting structure 120 includes an oblong hole or multi-row holes, etc., the operation method of adjusting the mounting position of the connecting member 300 in the second direction Y through the first mounting structure 120 is the same as the operation method of adjusting the mounting position of the locking device 200 described above. Therefore, the operation method will not be described in detail here.

[0092] The locking device 200 is provided on the connecting member 300; optionally, the locking device 200 can be fixedly assembled on the connecting member 300 by means of fastener connection, welding, etc.; or, the locking device 200 can also be installed on the connecting member 300 in a position-adjustable manner (for example, the mounting position can be adjusted along the first direction X or the second direction Y).

[0093] With such a setting, at least one row of the locking devices 200 in the locking group 201 can be assembled on the working end face 110 through the connecting member 300, and the connecting member 300 can be used to synchronously adjust the mounting positions of all the locking devices 200 in the locking group 201 in the second direction Y, so as to effectively improve the operation efficiency.

[0094] Please refer to Figure 2 、 Figure 4 and Figure 5 In some embodiments, a second mounting structure 310 is formed on the connecting member 300, and the locking device 200 is connected to the connecting member 300 through the second mounting structure 310; the second mounting structure 310 is configured to be able to adjust the mounting position of the locking device 200 in the second direction Y.

[0095] Optionally, the second mounting structure 310 includes, but is not limited to, structures such as oblong holes and multi-row holes formed on the working end face 110.

[0096] When the second mounting structure 310 includes an oblong hole formed on the connecting member 300, the length direction of the waist hole is arranged along the second direction Y; the locking device 200 can be fixedly assembled on the connecting member 300 by passing a fastener (such as a bolt, a screw, etc.) through the waist hole.

[0097] When it is necessary to adjust one or more of the locking devices 200 in the locking group 201 to be applicable to the to-be-assembled structure with inconsistent dimensions in the first direction X, the fastener of the locking device 200 to be adjusted can be loosened, and then the locking device 200 is operated to move and adjust along the second direction Y, and after adjusting to the preset position, the fastener is tightened to realize the adjustment and fixed assembly of the mounting position of one or more of the locking devices 200 in the locking group 201.

[0098] When the second mounting structure 310 includes multiple rows of holes (for example, two rows, three rows or more mounting holes spaced along the second direction Y) formed on the working end face 110, the locking device 200 can be fixedly assembled on the working end face 110 by a fastener (such as a bolt, a screw, etc.) passing through one row of the multiple rows of holes.

[0099] When it is necessary to adjust one or more of the locking devices 200 in the locking group 201 to be applicable to the to-be-assembled structure with inconsistent dimensions in the first direction X, the fastener can be disassembled, and the locking device 200 can be operated to move and adjust along the second direction Y. After adjusting to the preset position, the fastener is passed through the corresponding row of mounting holes to realize the adjustment and fixed assembly of the mounting positions of one or more of the locking devices 200 in the locking group 201.

[0100] With such a setting, on the basis that the connecting member 300 can adjust the mounting positions of all the locking devices 200 in the locking group 201 in the second direction Y, the second mounting structure 310 can be further used to adjust the mounting positions of the respective locking devices 200 in the second direction Y to be applicable to more sizes of to-be-assembled structures.

[0101] Please refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7 , in some embodiments, the locking device 200 includes a mounting base 210, a first locking member 220 hinged to the mounting base 210, and a second locking member 230 hinged to the mounting base 210; the first locking member 220 is configured to have a first locking state 221 capable of rotating to lock in the locking area portion 111, and a first unlocking state 222 capable of rotating away from the locking area portion 111; the second locking member 230 is configured to have a second locking state 231 capable of rotating to lock in the first locking member 220 to keep the first locking member 220 in the first locking state 221; the second locking member 230 is further configured to be able to rotate to a second unlocking state 232 to release the locking of the first locking member 220.

[0102] As Figure 3 shown, the first locking member 220 is in the first locking state 221, and the second locking member 230 is in the second locking state 231. Among them, the dotted lines in the figure show the styles after the first locking member 220 rotates to the first unlocking state 222 and the second locking member 230 rotates to the second unlocking state 232.

[0103] The mounting base 210 is disposed on the working end face 110; optionally, the mounting base 210 can be fixedly assembled on the working end face 110 by means of fastener connection, welding, etc.; alternatively, the mounting base 210 can be fixedly assembled on the connecting member 300 by means of fastener connection, welding, etc., and then assembled to the working end face 110 through the connecting member 300. The mounting base 210 can be, but is not limited to, a block structure, a plate structure, a bracket structure, or a combination of the above structures, etc.

[0104] The first locking member 220 is hinged to the mounting base 210; the first locking member 220 can rotate around the hinge point, and the first locking member 220 can rotate towards the locking area 111 to the first locking state 221, or away from the locking area 111 to the first unlocking state 222.

[0105] It can be understood that in the first locking state 221, the first locking member 220 can press and lock the structure to be assembled (such as the chassis) placed in the locking area 111. In the first unlocking state 222, the first locking member 220 rotates away from the locking area 111, and the structure to be assembled placed in the locking area 111 can be moved.

[0106] Optionally, the first locking member 220 includes, but is not limited to, a locking rod, a locking plate, a locking block, a locking bracket, etc. The number of the first locking members 220 can be one or any number more than one.

[0107] The second locking member 230 is hinged to the mounting base 210; the second locking member 230 can rotate around the hinge point. When the first locking member 220 rotates to the first locking state 221, the second locking member 230 can rotate to the second locking state 231. At this time, the second locking member 230 can lock the first locking member 220 in the first locking state 221, and the second locking member 230 will block the path of the first locking member 220 rotating away from the locking area 111, so that the first locking member 220 can maintain the first locking state 221.

[0108] Moreover, the second locking member 230 can also rotate to the second unlocking state 232. At this time, the second locking member 230 rotates away from the first locking member 220 and no longer blocks the path of the first locking member 220 rotating away from the locking area 111, so as to release the locking of the first locking member 220; when the second locking member 230 is in the second unlocking state 232, the first locking member 220 can switch between the first locking state 221 and the first unlocking state 222.

[0109] Optionally, the rotation axes of the second locking member 230 and the first locking member 220 can be set to be parallel. Exemplarily, in some embodiments, the first locking member 220 includes a first locking portion and a first hinged portion. The first locking portion is used to lock the structure to be spliced, and the first hinged portion is hinged to the mounting base 210; the second locking member 230 includes an operating portion and two spaced second hinged portions integrally formed with the operating portion. The two second hinged portions are hinged to the same location on the mounting base 210; wherein, the first hinged portion passes through between the two second hinged portions. When the first locking member 220 rotates to the first locking state 221 and the second locking member 230 rotates to the second locking state 231, the direction in which the first locking portion abuts against the structure to be assembled is parallel to the length direction of the second hinged portion. Thus, when the first locking portion has a tendency to disengage from the structure to be assembled, the direction of the force exerted by the first locking portion on the second locking member 230 is parallel to the radial direction of the rotation of the second locking member 230; therefore, the second locking member 230 can form a locking effect on the first locking member 220.

[0110] With such a setting, the first locking member 220 can be rotated to the first locking state 221, and then the second locking member 230 can be rotated to the second locking state 231. Thus, the second locking member 230 can be locked to the first locking member 220 so that the first locking member 220 remains in the first locking state 221. At this time, the first locking member 220 can press and lock the structure to be assembled placed in the locking area 111; meanwhile, the second locking member 230 can be rotated to the second unlocking state 232 to unlock the first locking member 220, so that the first locking member 220 can rotate away from the locking area 111 and switch to the first unlocking state 222 to unlock the structure to be assembled placed in the locking area 111.

[0111] Please refer to Figure 6 and Figure 7 , in some embodiments, the locking device 200 further includes an abutting structure 240. The abutting structure 240 is disposed on the first locking member 220, and the abutting structure 240 is used to abut against the structure to be assembled.

[0112] The abutting structure 240 is used to abut and press against the structure to be assembled to replace the contact between the first locking member 220 and the structure to be assembled. Optionally, the abutting structure 240 includes, but is not limited to, structures such as an abutting block, an abutting plate, and an abutting column. The abutting structure 240 can be connected to the first locking member 220 by means of snap connection, fastener connection, etc.

[0113] Among them, the abutting structure 240 can be selected from hard structural members such as steel pads and hard nylon blocks to achieve a better abutting and pressing effect.

[0114] With such a setting, the abutting structure 240 is used to replace the first locking member 220 to form an abutting and pressing connection with the assembling structure, so as to reduce the wear degree of the first locking member 220, and only the abutting structure 240 needs to be replaced after the abutting structure 240 is worn.

[0115] Please refer to Figure 6 and Figure 7 , in some embodiments, the locking device 200 further includes a buffer structure 250, and the buffer structure 250 is disposed between the abutting structure 240 and the first locking member 220.

[0116] Among them, the buffer structure 250 includes, but is not limited to, structural members with a buffering effect such as buffer blocks, buffer pads, and buffer layers. The buffer structure 250 can be made of rubber, silica gel, soft plastic, etc.

[0117] The buffer structure 250 is disposed between the abutting structure 240 and the first locking member 220; optionally, the buffer structure 250 can be clamped between the abutting structure 240 and the first locking member 220; or, the buffer structure 250 can be fixed between the abutting structure 240 and the first locking member 220 by means of bonding, fastener connection, etc.

[0118] With such a setting, when the abutting structure 240 abuts against the structure to be assembled, the buffer structure 250 can form a buffering effect, so as to effectively reduce the damage to the structure to be assembled when the abutting structure 240 abuts against the structure to be assembled.

[0119] Please refer to Figure 1 , Figure 2 and Figure 8 , in some embodiments, the assembling device 1000 for vehicle chassis assembly further includes a guiding mechanism 400, and on at least one side of the tooling table 100 in the first direction X, a guiding mechanism 400 is provided.

[0120] It can be understood that when the structure to be assembled is locked in the locking area 111, the opposite ends of the structure to be assembled in the second direction Y are locked by the locking device 200, and at least one end of the structure to be assembled in the first direction X is used for assembling other structures (such as the front subframe, the rear subframe, etc.).

[0121] The guiding mechanism 400 is used to achieve a guiding effect. When other structures are sent from the outside to one end of the structure to be assembled in the first direction X, for example, they are sent by a lifting trolley; the guiding mechanism 400 can guide the lifting trolley so that the lifting trolley can drive other structures to be sent to a preset position, and then the lifting trolley lifts other structures, so as to perform assembling and welding operations on the structure to be assembled and other structures.

[0122] Optionally, the guiding mechanism 400 can be, but is not limited to, a guide rail, a guiding and limiting structure, etc. The guiding mechanism 400 can be arranged on either side of the tooling table 100 in the first direction X; alternatively, the guiding mechanism 400 can be arranged on both opposite sides of the tooling table 100 in the first direction X.

[0123] The guiding mechanism 400 can be arranged on one side of the tooling table 100 and have no connection relationship with the tooling table 100; alternatively, the guiding mechanism 400 can be connected to the tooling table 100 by means of fastener connection, welding, snap connection, etc.

[0124] With such an arrangement, by arranging the guiding mechanism 400 on at least one side of the tooling table 100 in the first direction X, the guiding mechanism 400 can guide the fed structural members, so as to improve the assembly accuracy of the fed structural members and the structural members to be assembled placed on the working end face 110.

[0125] Please refer to Figure 2 and Figure 8 , in some embodiments, the guiding mechanism 400 includes a guiding base 410, and the guiding base 410 includes a first part 411 and two second parts 412 arranged at opposite ends of the first part 411; the first part 411 and the two second parts 412 at opposite ends enclose a limiting area part 413.

[0126] The guiding base 410 is used to guide other structures fed to one side of the structure to be assembled along the first direction X.

[0127] The guiding base 410 includes a first part 411 and two second parts 412. The first part 411 can be, but is not limited to, a plate structure, a block structure, a bracket structure, etc.; the first part 411 is used to limit the fed other structures.

[0128] The second part 412 can be, but is not limited to, a plate structure, a block structure, a bracket structure, etc.; the second part 412 is used to guide the fed other structures.

[0129] The first part 411 and the two second parts 412 at opposite ends enclose a limiting area part 413. Thus, after other structures are fed into the limiting area part 413, they can move along the first direction X and towards the second part 412 through the guiding action of the second part 412 until they abut against the second part 412 and stop moving, and reach the preset position.

[0130] Exemplarily, in some embodiments, both the first part 411 and the second part 412 can be selected as plate structures, and the two second parts 412 are integrally formed at opposite ends of the first part 411 respectively, and the first part 411 and the second part 412 are combined to form a U-shaped structure.

[0131] With such a setting, a limiting area portion 413 can be formed by enclosing between the first part 411 and the two second parts 412. The fed structural member can enter the limiting area portion 413 to play a role of limiting and guiding, so as to improve the assembling accuracy of the fed structural member and the structural member to be assembled placed on the working end face 110.

[0132] Please refer to Figure 8 , in some embodiments, the two second parts 412 are flared between the ends facing away from the first part 411.

[0133] It can be understood that the flared shape refers to a horn-shaped structure formed by one second part 412 deviating away from the other second part 412 at the end facing away from the first part 411.

[0134] With such a setting, when the structural member is fed into the limiting area portion 413 from the outside, the fed structural member can play a role of guiding and correcting deviation when passing between the two flared second parts 412, so as to improve the assembling accuracy of the fed structural member and the structural member to be assembled placed on the working end face 110.

[0135] Please refer to Figure 8 , in some embodiments, a limiting structure 420 facing the limiting area portion 413 is provided on the first part 411.

[0136] Among them, the limiting structure 420 includes, but is not limited to, structures such as limiting blocks, limiting brackets, limiting plates, and limiting columns.

[0137] Exemplarily, in some embodiments, the limiting structure 420 may include a limiting bracket, a limiting block, and a limiting cylinder. The limiting bracket can be installed on the first part 411 through fasteners. A limiting block is provided on one side of the limiting bracket facing the limiting area portion 413 along the first direction X, and a limiting cylinder is installed on the limiting bracket. The piston of the limiting cylinder faces the limiting area portion 413 along the first direction X; the limiting cylinder and the limiting block can form a limiting effect on other fed structures.

[0138] With such a setting, the limiting structure 420 is used to limit the fed structural member, so that the structural member can be assembled with the structural member to be assembled more precisely.

[0139] Please refer to Figure 8 , in some embodiments, a supporting structure 430 facing the limiting area portion 413 is provided on the second part 412.

[0140] Among them, the supporting structure 430 includes, but is not limited to, structures such as supporting blocks, supporting rods, supporting brackets, supporting plates, supporting strips, supporting rollers, and supporting wheels.

[0141] Exemplarily, in some embodiments, the support structure 430 may include support bars and a plurality of support brackets. The second part 412 is arranged with a plurality of support brackets along the first direction X, and the plurality of support brackets are commonly connected to the support bars, so that the support bars face the limiting area part 413 along the second direction Y.

[0142] With such an arrangement, the support structure 430 is used to limit and support the structural members fed into the limiting area part 413, so that the structural members can be assembled with the structure to be assembled more precisely.

[0143] Please refer to Figure 8 , in some embodiments, the second part 412 is provided with a guide roller 440 at one end facing away from the first part 411.

[0144] With such an arrangement, when the structural members are fed from the outside into the locking area part 111, the guide roller 440 can cooperate with the flared second part 412 to form a better guiding effect on the fed structural members.

[0145] Please refer to Figure 1 and Figure 8 , in some embodiments, the assembling device 1000 for vehicle chassis assembly further includes a chain (not shown in the figure), and one end of the chain is connected to the guiding mechanism 400.

[0146] Wherein, the chain can be but is not limited to structures such as fixed chains, ropes, etc.

[0147] One end of the chain is connected to the guiding mechanism 400, and the other end of the chain can be connected to other structures fed in; thus, the chain can lock other structures to improve their stability.

[0148] Exemplarily, when other structures are fed into the limiting area part 413 through a lifting trolley and reach a preset position, the chain can be used to lock other structures to the lifting trolley, so that during the process of the lifting trolley lifting other structures, the stability of other structures is better.

[0149] Next, the assembly work of the embodiments of the present application will be described in detail according to specific embodiments.

[0150] Please refer to Figures 1 to 8 , the assembling device 1000 for vehicle chassis assembly includes a tooling table 100, a guiding mechanism 400 and a plurality of locking devices 200; the tooling table 100 has a working end face 110, and the plurality of locking devices 200 are arranged in sequence along the first direction X to form two rows of locking groups 201, and the two rows of locking groups 201 are spaced apart along the second direction Y, and the working end face 110 forms a locking area part 111 between the two rows of locking groups 201; wherein, the first direction X is the length direction of the working end face 110, and the second direction Y is the width direction of the working end face 110.

[0151] A first mounting structure 120 is provided on the working end face 110. In the present embodiment, the first mounting structure 120 includes a slotted hole, and the length direction of the slotted hole is arranged along the second direction Y. The assembling device 1000 for vehicle chassis assembly further includes a connecting member 300. In the present embodiment, the connecting member 300 can be a connecting plate; the connecting plate is connected to the working end face 110 by a fastener passing through the slotted hole. Specifically, two connecting plates are connected to the working end face 110 at intervals along the second direction Y, and a row of locking groups 201 are respectively connected to the two connecting plates; thus, the distance between the two rows of locking devices 200 can be adjusted by adjusting the mounting position of the connecting plate on the working end face 110, so as to improve the applicability of the assembling device 1000 for vehicle chassis assembly.

[0152] Guiding mechanisms 400 are provided at both opposite ends of the tooling table 100 in the first direction X. The guiding mechanism 400 includes a guiding base 410, and the guiding base 410 includes a first part 411 and two second parts 412 provided at opposite ends of the first part 411; the first part 411 and the second parts 412 at opposite ends enclose a limiting area part 413.

[0153] In this way, when assembling the vehicle body structure, the chassis can be sent to the working end face 110 by a hoisting device, and the chassis is clamped and locked by the locking device 200; then the front subframe and the rear subframe are respectively sent to both opposite ends of the tooling table 100 in the first direction X by a lifting trolley, and the guiding mechanism 400 guides and positions the lifting trolley. The lifting trolley can lift the front subframe and the rear subframe to a preset position, so that the front subframe and the rear subframe can be assembled and welded with the chassis.

[0154] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
