Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and in particular to a vehicle frame assembly and a production process. Background Art

[0002] The frame assembly refers to the main structural component on the automobile chassis, which is used to support and connect various parts such as the body, engine, suspension system and transmission system. The frame assembly is usually welded by front and rear beams, main beams, longitudinal beams and beams.

[0003] In the prior art, a large number of frame assembly production and corresponding devices are also disclosed. Among them, for example, a Chinese patent with publication number CN116495057A discloses a frame assembly and a production process. The frame assembly includes a chassis longitudinal beam, two chassis longitudinal beams are provided, and a side panel assembly and a chassis cross beam are provided on the chassis longitudinal beam. The chassis cross beam is provided between the two chassis longitudinal beams, a frame rear assembly and a frame front assembly; in addition, the production process provides a first manipulator and a second manipulator.

[0004] When the above-mentioned prior art welds the frame assembly, the frame assembly is first divided into multiple modules, and then each module is processed in turn. After the processing is completed, the modules are welded. During welding, the first manipulator grabs and places the two chassis longitudinal beams on the working platform, and then grabs and places the chassis cross beams at the designated position, and the chassis longitudinal beams and the chassis cross beams are welded together by the second manipulator; the rear frame assembly is hoisted and placed on the working platform and abutted against the side panel assembly, and the second manipulator welds the side panel assembly and the rear frame assembly together; the first manipulator grabs the front frame assembly, and the second manipulator welds the front frame assembly to the side panel assembly to complete the production of the frame assembly.

[0005] However, in the process of welding the frame assembly using the above-mentioned prior art, there are still the following shortcomings:

[0006] 1. Although the above-mentioned prior art uses the first manipulator and the second manipulator to sequentially hoist and weld multiple modules of the frame assembly, it is necessary to frequently take and weld different modules, which affects work efficiency. After the modules are placed in the specified positions, they are not fixed by corresponding limit positions. Therefore, it is impossible to ensure whether there are adverse phenomena such as offset between the modules after welding is completed.

[0007] 2. When welding between modules, the above-mentioned prior art only lifts the module by the first manipulator and places it in the specified position, so it is impossible to achieve rapid assembly between the modules, and the placed modules cannot be limited, which may easily cause the modules to fall due to not being placed stably, thereby affecting work efficiency and easily causing deformation and defects of the frame.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the welding methods of the vehicle frame assembly in the prior art. Summary of the invention

[0009] In order to solve the above problems, the present invention provides a frame assembly, including two longitudinal beams arranged in parallel, with clip sleeves provided at both ends of the longitudinal beams, and anti-collision beams for protecting the front and rear sides of the vehicle are provided between two clip sleeves corresponding to the positions of the two longitudinal beams, and multiple cross beams are equidistantly provided between the two longitudinal beams along the length direction.

[0010] The anti-collision beams are detachably connected to the clamping sleeves, and the cross beams and the longitudinal beams are connected to each other via support members.

[0011] As a preferred technical solution of the present invention, a placement groove for accommodating the anti-collision beam is provided at the upper end of the clamping sleeve, a vertical column is provided in the middle of the bottom wall of the placement groove, and a through hole is provided on the anti-collision beam for being sleeved on the outer wall of the vertical column, so as to weld the anti-collision beam to the placement groove and the vertical column.

[0012] As a preferred technical solution of the present invention, two installation grooves connected to the placement groove are symmetrically opened along the vertical column inside the snap-in sleeve, and a top-extending elastic part is arranged inside the installation groove. A limit block is installed at one end of the top-extending elastic part close to the placement groove for limiting and fixing the installed anti-collision beam.

[0013] As a preferred technical solution of the present invention, the side of the limit block away from the top extending elastic member gradually inclines from top to bottom toward the side close to the vertical column, the bottom of the inclined surface of the limit block extends out of the installation slot and is located in the placement slot in the initial state, and the top of the inclined surface of the limit block does not extend out of the installation slot.

[0014] As a preferred technical solution of the present invention, the support member includes a horizontal support plate installed on opposite sides of the two longitudinal beams, the upper end of the horizontal support plate is provided with buckles equidistantly along its length direction, and the cross beam is commonly clamped between the corresponding buckles on the two horizontal support plates.

[0015] As a preferred technical solution of the present invention, both ends of the beam are provided with pre-installed blocks, the buckles are installed on the side walls of the pre-installed blocks and abut against the bottom of the beam, and the lower end of the pre-installed blocks is provided with plug-in blocks;

[0016] A plurality of plug holes corresponding to the positions of the plug blocks are equidistantly arranged along the length direction on the horizontal support plate.

[0017] As a preferred technical solution of the present invention, the outer wall of the pre-installation block is symmetrically provided with two linkage pieces, and two supporting feet are provided on the side of the linkage piece away from the pre-installation block, and the side of the supporting feet away from the linkage piece is gradually inclined upward; the upper end of the horizontal support plate is provided with a plurality of locking groups corresponding to the position of the pre-installation block;

[0018] Each locking group includes two fixing plates symmetrically arranged along the insertion hole, and the side walls of the fixing plates are provided with two stop plates matched with the supporting feet, and the side of the stop plate away from the fixing plate gradually tilts downward.

[0019] In addition, the present invention also provides a production process of a frame assembly, comprising the following steps:

[0020] S1: Assembly of anti-collision beam: First, place the two longitudinal beams in parallel according to the length of the anti-collision beam, and then install the anti-collision beam on the clamping sleeve at the end of the longitudinal beam to facilitate the rapid assembly of the anti-collision beam;

[0021] S2: Crossbeam assembly: Install the crossbeam on the support of the longitudinal beam side wall to facilitate the rapid assembly of the crossbeam, thereby completing the pre-assembly of the frame assembly;

[0022] S3: Frame assembly welding: Weld the joints between the anti-collision beam, cross beam and longitudinal beam in the pre-assembled frame assembly.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The present invention can separate the assembly and welding of the anti-collision beam, the cross beam and the longitudinal beam through pre-assembly, effectively replacing the traditional working method of welding while taking materials, thereby avoiding frequent taking of materials and affecting work efficiency; during the process, the anti-collision beam and the cross beam can be limited and fixed respectively through the clamping sleeve and the support member, thereby improving the stability of the pre-assembled frame assembly and avoiding the phenomenon of assembly deviation.

[0025] 2. The present invention achieves rapid assembly of the anti-collision beam by clipping the anti-collision beam into the placement groove, and the cooperation of the through hole and the vertical column can provide a limit to the anti-collision beam in the circumferential rotation direction, thereby preventing the anti-collision beam from being subjected to a large torsional force during subsequent welding, transportation and use, which may cause the weld between the anti-collision beam and the clamping sleeve to crack, thereby effectively ensuring the stability of the anti-collision beam.

[0026] 3. In the present invention, after the anti-collision beam is installed in the placement groove, the limit block pops out under the action of the top-extending elastic member and abuts against the top of the anti-collision beam to limit and fix it, preventing the anti-collision beam from falling off from the placement groove at will and causing deformation and defects, thereby ensuring the stability of the pre-assembly of the frame assembly.

[0027] Fourth, the present invention can limit and fix the pre-installed blocks through the cooperation between the support feet and the stop plate, and then limit and fix the crossbeam. In addition, the pre-installed blocks at both ends of the crossbeam slide against the side walls of the longitudinal beam, so that the crossbeam is limited in multiple directions, thereby preventing the crossbeam from falling during the transportation of the frame assembly, thereby avoiding repeated assembly of the crossbeam to affect efficiency.

[0028] 5. The present invention drives the double-headed screw to rotate through the positioning column, and can drive the crossbeam to move synchronously through the auxiliary plate and the telescopic rod, so as to realize the synchronous adjustment of the spacing between multiple crossbeams, and then the spacing of the crossbeams can be adjusted according to actual production needs, and multiple crossbeams are composed of a crossbeam assembly through linkage joints and telescopic rods, so that multiple crossbeams can be assembled with the longitudinal beam at the same time, which can further improve efficiency.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-Figure 8While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0040] The embodiment of the present application discloses a frame assembly, which explains that the frame assembly is mainly used in the production and assembly process of the frame assembly. In terms of technical effect, the assembly and welding between the anti-collision beam 3, the cross beam 4 and the longitudinal beam 1 can be separated by pre-assembly, effectively replacing the traditional working method of welding while taking materials, thereby avoiding frequent taking of materials and affecting work efficiency; especially in the pre-assembly process of the frame assembly, the anti-collision beam 3 and the cross beam 4 can be limited and fixed after being assembled with the longitudinal beam 1, so as to avoid the anti-collision beam 3 from being subjected to a large torsional force during subsequent welding, transportation and use, which may cause the weld between it and the clamping sleeve 2 to crack, and to prevent the cross beam 4 from falling during the transportation of the frame assembly, so as to avoid repeated assembly of the cross beam 4 and affect the efficiency, thereby effectively ensuring the stability of the assembled frame assembly. Furthermore, the frame assembly can also form a cross beam 4 assembly with multiple cross beams 4, so as to facilitate the simultaneous assembly of multiple cross beams 4 with the longitudinal beam 1, thereby further improving efficiency. In addition, the spacing of the cross beams 4 can also be adjusted according to actual production needs. Example

[0041] Reference Figure 1 As shown, a frame assembly includes two longitudinal beams 1 arranged in parallel, and a clamping sleeve 2 is provided at both ends of the longitudinal beams 1. An anti-collision beam 3 for protecting the front and rear sides of the vehicle is provided between two clamping sleeves 2 corresponding to the positions of the two longitudinal beams 1, and a plurality of cross beams 4 are equidistantly arranged between the two longitudinal beams 1 along the length direction. The anti-collision beams 3 are clamped to the clamping sleeves 2 in a detachable manner, and the cross beams 4 and the longitudinal beams 1 are clamped via a support member 5.

[0042] It should be noted that the longitudinal beam 1 and the clip sleeves 2 at both ends are connected in a pre-assembled manner. In order to improve the stability between the longitudinal beam 1 and the anti-collision beam 3, in the present embodiment, the connection method between the longitudinal beam 1 and the clip groove is preferably welding, that is, between the pre-assembly of the longitudinal beam 1 and the anti-collision beam 3, the two ends of the longitudinal beam 1 are pre-arranged with the clip sleeves 2 by the aforementioned preferred welding method, so as to facilitate the rapid pre-assembly of the anti-collision beam 3.

[0043] In the specific implementation process, the two longitudinal beams 1 are first placed in parallel according to the lengths of the anti-collision beam 3 and the cross beam 4, and then the anti-collision beam 3 and the cross beam 4 are pre-assembled with the longitudinal beam 1 in turn, so that the longitudinal beam 1, the anti-collision beam 3 and the cross beam 4 are pre-assembled into a frame assembly, and then the connection between the anti-collision beam 3, the cross beam 4 and the longitudinal beam 1 is welded.

[0044] In addition, the assembled anti-collision beam 3 and cross beam 4 can be limited and fixed respectively by the clamping sleeve 2 and the support member 5 to prevent them from loosening and falling, thereby improving the stability of the pre-assembled frame assembly and avoiding the phenomenon of assembly deviation.

[0045] In this way, the assembly and welding between the anti-collision beam 3, the cross beam 4 and the longitudinal beam 1 can be carried out separately through pre-assembly, which effectively replaces the traditional working method of welding while taking materials, thereby avoiding frequent taking of materials and affecting work efficiency.

[0046] Reference Figure 1 and Figure 2 As shown, in order to facilitate the rapid assembly of the anti-collision beam 3 and the snap-in sleeve 2, as well as the stability of the anti-collision beam 3 and the longitudinal beam 1 after assembly, in the present embodiment, a placement groove 21 for accommodating the anti-collision beam 3 is provided at the upper end of the snap-in sleeve 2, and a vertical column 22 is provided in the middle of the inner bottom wall of the placement groove 21, and a through hole for being sleeved on the outer wall of the vertical column 22 is provided on the anti-collision beam 3, so as to weld the anti-collision beam 3 to the placement groove 21 and the vertical column 22; it should be noted that in order to ensure the stability of the anti-collision beam 3 after welding with the snap-in sleeve 2, the vertical column 22 is required to provide a limiting effect on the anti-collision beam 3, based on this, the vertical column 22 used in the present embodiment is preferably integrally formed with the snap-in sleeve 2.

[0047] During the specific implementation process, the through hole of the anti-collision beam 3 is aligned with the vertical column 22, and then the anti-collision beam 3 is pressed down so that the vertical column 22 is inserted into the through hole and the anti-collision beam 3 is snapped into the placement groove 21, thereby realizing the rapid assembly of the anti-collision beam 3, and the connection between the through hole and the vertical column 22 and between the anti-collision beam 3 and the placement groove 21 facilitates welding between the anti-collision beam 3 and the snap-in sleeve 2.

[0048] In addition, the mutual cooperation between the through hole and the vertical column 22 can provide a limit to the circumferential rotation direction of the anti-collision beam 3, thereby preventing the anti-collision beam 3 from being subjected to a large torsional force during subsequent welding, transportation and use, which may cause the weld between it and the clamping sleeve 2 to crack, thereby effectively ensuring the stability of the anti-collision beam 3.

[0049] Reference Figure 2 and Figure 3 As shown, after the anti-collision beam 3 is assembled with the longitudinal beam 1 through the clamping sleeve 2, it needs to be transported as a whole to the welding position for welding. Therefore, in order to prevent the anti-collision beam 3 from falling off during transportation, the anti-collision beam 3 needs to be limited and fixed. Based on this, in this embodiment, two installation grooves connected to the placement groove 21 are symmetrically opened along the vertical column 22 inside the clamping sleeve 2, and a top-extending elastic member 23 is arranged inside the installation groove. A limit block 24 for limiting and fixing the installed anti-collision beam 3 is installed at one end of the top-extending elastic member 23 close to the placement groove 21.

[0050] Furthermore, in this embodiment, the side of the limit block 24 away from the extending elastic member 23 gradually tilts from top to bottom toward the side close to the vertical column 22. In the initial state, the extending elastic member 23 always applies an extending force to the side of the vertical column 22 to the limit block 24, so that the bottom of the inclined surface of the limit block 24 extends out of the installation slot and is located in the placement slot 21 in the initial state, and the top of the inclined surface of the limit block 24 does not extend out of the installation slot.

[0051] In the specific implementation process, the anti-collision beam 3 is aligned with the placement groove 21 and then pressed downward, so that the vertical column 22 is inserted into the through hole, and the anti-collision beam 3 is stuck in the placement groove 21. At this time, the anti-collision beam 3 is in contact with the inclined surface of the limit block 24 and the limit block 24 is squeezed into the installation groove; after the anti-collision beam 3 is installed in place, the top of the anti-collision beam 3 is located at the lower end of the limit block 24, so that the limit block 24 pops up and abuts against the top of the anti-collision beam 3 under the action of the top elastic member 23. Since the bottom of the limit block 24 is a horizontal plane, the limit block 24 can limit and fix the anti-collision beam 3 to prevent the anti-collision beam 3 from falling off from the placement groove 21 at will when the assembled frame assembly is transported, thereby ensuring the stability of the pre-assembly of the frame assembly.

[0052] Reference Figure 1 As shown, in order to further improve the production efficiency of the frame assembly, the present application can also pre-assemble the cross beam 4 on the basis of the pre-assembly of the anti-collision beam 3. Specifically, in this embodiment, the support member 5 is used to achieve rapid pre-assembly between the cross beam 4 and the longitudinal beam 1. Specifically, the support member 5 includes a horizontal support plate 51 installed on the opposite sides of the two longitudinal beams 1, and the upper end of the horizontal support plate 51 is equidistantly provided with buckles 52 along its length direction, and the cross beam 4 is commonly clamped between the corresponding snap-in openings on the two horizontal support plates 51.

[0053] It should be noted that in order to facilitate the rapid pre-assembly of the crossbeam 4, as well as the stability and supporting strength of the crossbeam 4 and the longitudinal beam 1 after assembly, the horizontal support plate 51 provided in this embodiment is preferably pre-welded to the longitudinal beam 1, and the clip 52 and the horizontal support plate 51 are also preferably welded. In addition, the clip 52 can adjust its position according to the car model, that is, adjust the position of the crossbeam 4 according to actual production requirements.

[0054] In the specific implementation process, the cross beam 4 is snapped into the two corresponding buckles 52 on the two horizontal support plates 51, so that the cross beam 4 can be quickly pre-assembled, and then the connection between the cross beam 4 and the longitudinal beam 1 and the buckle 52 can be welded. The horizontal support plate 51 can also provide an upward supporting force to the cross beam 4, thereby ensuring the service strength of the cross beam 4.

[0055] Reference Figure 4As shown, in order to ensure the stability of the crossbeam 4, it is necessary to increase the contact area of ​​the welding between its end and the longitudinal beam 1. Based on this, in this embodiment, pre-installation blocks 41 are provided at both ends of the crossbeam 4, and the clips 52 are installed on the side walls of the pre-installation blocks 41 and abut against the bottom of the crossbeam 4. A plug-in block 42 is installed at the lower end of the pre-installation block 41; a plurality of plug-in holes 43 corresponding to the positions of the plug-in blocks 42 are equidistantly provided on the horizontal support plate 51 along the length direction.

[0056] In the specific implementation process, the crossbeam 4 and the pre-installation block 41 and the clip 52 are pre-assembled by welding, and then the crossbeam 4 together with the pre-installation blocks 41 at both ends are installed as a whole on the horizontal support plate 51, so that the plug-in block 42 is inserted into the socket 43. By inserting the plug-in block 42 into the socket 43 at different positions, the position of the crossbeam 4 can also be adjusted according to production requirements.

[0057] In addition, the plug-in block 42 can replace the welding between the end of the cross beam 4 and the longitudinal beam 1 and the horizontal support plate 51, and the contact area between the plug-in block 42 and the longitudinal beam 1 and the horizontal support plate 51 is larger than the contact area between the cross beam 4 and the longitudinal beam 1 and the horizontal support plate 51, thereby improving the stability of the cross beam 4 after welding and ensuring the use strength of the cross beam 4. Example

[0058] Reference Figure 5 and Figure 6 As shown, on the basis of Example 1, in order to prevent the beam 4 from falling during transportation after pre-assembly, it is necessary to perform corresponding limiting treatment on the beam 4. Based on this, in this embodiment, two linkage plates 411 are symmetrically arranged on the outer wall of the pre-installation block 41, and two support feet 412 are arranged on the side of the linkage plate 411 away from the pre-installation block 41; a plurality of locking groups corresponding to the position of the pre-installation block 41 are arranged on the upper end of the horizontal support plate 51, and each locking group includes two fixing plates 413 symmetrically arranged along the insertion hole 43, and the side walls of the fixing plates 413 are provided with two shifting plates 414 cooperating with the support feet 412.

[0059] It should be noted that the side of the support leg 412 away from the linkage plate 411 gradually tilts upward, and the side of the shift plate 414 away from the fixed plate 413 gradually tilts downward, that is, the support leg 412 and the shift plate 414 are parallel; in addition, the fixed plate 413 is a spring that can be elastically deformed under the action of external force.

[0060] In the specific implementation process, when the pre-installation block 41 is installed on the horizontal support plate 51 by the crossbeam 4, the support leg 412 and the stop plate 414 are in the same vertical plane. When the support leg 412 abuts against the stop plate 414, an extrusion force is applied to the fixed plate 413, so that the fixed plate 413 bends to the side away from the pre-installation block 41 and drives the stop plate 414 to synchronously give way to the support leg 412. After the pre-installation block 41 is installed in place, the fixed plate 413 drives the stop plate 414 to reset and clamp it on the upper end of the support leg 412 (at Figure 6 As shown in the figure); the pre-installed block 41 can be limited and fixed by the cooperation between the support foot 412 and the stop plate 414, and then the cross beam 4 can be limited and fixed. In addition, the pre-installed blocks 41 at both ends of the cross beam 4 slide against the side wall of the longitudinal beam 1, so that the cross beam 4 is limited in all directions, thereby preventing the cross beam 4 from falling during the transportation of the frame assembly, thereby avoiding repeated assembly of the cross beam 4 to affect the efficiency. Example

[0061] Reference Figure 7 and Figure 8 As shown, on the basis of the second embodiment, in order to facilitate the corresponding adjustment of the spacing between the cross beams 4 on the frames of automobiles of different models, a pre-adjustment component 6 for quickly adjusting the spacing between multiple cross beams 4 is also provided in this embodiment, which can not only adjust the spacing between the cross beams 4, but also enable multiple cross beams 4 to be assembled on the longitudinal beam 1 at the same time. The pre-adjustment component 6 is specifically as follows: two linkage joints 61 are symmetrically rotated along the length direction on the cross beam 4, and a telescopic rod 62 is commonly arranged between two adjacent linkage joints 61. The telescopic rod 62 consists of two fixed sections and one telescopic section. The outer walls of the two telescopic rods 62 between the two adjacent cross beams 4 are commonly sleeved with two auxiliary plates 63, and the auxiliary plates 63 are sleeved on the outer walls of the fixed sections of the telescopic rods 62.

[0062] Furthermore, in this embodiment, a positioning column 64 is rotatably penetrated in the middle of the crossbeam 4, and a double-headed screw 66 that passes through the auxiliary plate 63 by a threaded connection is installed between two adjacent positioning columns 64 through a telescopic shaft 65, and the outer wall of the double-headed screw 66 is symmetrically provided with two transmission threads and a fixing ring 67 for limiting the moving range of the auxiliary plate 63; it should be noted that the telescopic end and the fixed end of the telescopic shaft 65 can only slide relative to each other and cannot rotate relative to each other, and the telescopic shaft 65, the double-headed screw 66 and the positioning column 64 rotate together.

[0063] In the specific implementation process, the positioning column 64 is rotated, and the positioning column 64 drives the double-headed screw 66 to rotate synchronously through the telescopic shaft 65. The double-headed screw 66 rotates and drives the two auxiliary plates 63 on its outer wall to move relative to or away from each other, so that the auxiliary plate 63 drives the beam 4 to move synchronously through the fixed section of the telescopic rod 62. During this period, the telescopic shaft 65 adaptively retracts and retracts; thereby, the synchronous adjustment of the spacing between multiple beams 4 is achieved, and the spacing of the beams 4 can be adjusted according to actual production needs, and multiple beams 4 are composed of a beam 4 assembly through the linkage joint 61 and the telescopic rod 62. After the spacing adjustment of the beams 4 is completed, multiple beams 4 can be assembled with the longitudinal beam 1 at the same time, which can further improve efficiency.

[0064] In addition, the present invention also provides a production process of a frame assembly, comprising the following steps:

[0065] S1: Assembling the anti-collision beam 3: First, place the two longitudinal beams 1 in parallel according to the length of the anti-collision beam 3, and then pre-assemble the anti-collision beam 3 and the cross beam 4 with the longitudinal beam 1 in turn. When assembling the anti-collision beam 3, align the through hole of the anti-collision beam 3 with the vertical column 22 and press it down so that the vertical column 22 is inserted into the through hole and the anti-collision beam 3 is stuck in the placement groove 21; at this time, the top of the anti-collision beam 3 is located at the lower end of the limit block 24, and the limit block 24 pops up and rests on the top of the anti-collision beam 3 under the action of the top elastic member 23 and limits and fixes it, so as to prevent the anti-collision beam 3 from falling off from the placement groove 21 at will when transporting the assembled frame assembly, thereby ensuring the stability of the pre-assembly of the frame assembly.

[0066] In addition, the mutual cooperation between the through hole and the vertical column 22 can provide a limit to the circumferential rotation direction of the anti-collision beam 3, thereby preventing the anti-collision beam 3 from being subjected to a large torsional force during subsequent welding, transportation and use, which may cause the weld between it and the clamping sleeve 2 to crack, thereby effectively ensuring the stability of the anti-collision beam 3.

[0067] S2: Assembly of the crossbeam 4: The crossbeam 4 and the pre-installation block 41 and the clip 52 are pre-assembled by welding, and then the crossbeam 4 together with the pre-installation blocks 41 at both ends are integrally installed on the horizontal support plate 51, so that the plug-in block 42 is inserted into the socket 43, so that the crossbeam 4 can be quickly pre-assembled. By inserting the plug-in block 42 into the socket 43 at different positions, the position of the crossbeam 4 can also be adjusted according to production requirements.

[0068] In addition, the plug-in block 42 can replace the welding between the end of the cross beam 4 and the longitudinal beam 1 and the horizontal support plate 51, and the contact area between the plug-in block 42 and the longitudinal beam 1 and the horizontal support plate 51 is larger than the contact area between the cross beam 4 and the longitudinal beam 1 and the horizontal support plate 51, thereby improving the stability of the cross beam 4 after welding and ensuring the use strength of the cross beam 4.

[0069] When the crossbeam 4 drives the pre-installation block 41 to be installed on the horizontal support plate 51, the support legs 412 and the stop plate 414 cooperate with each other to limit and fix the pre-installation block 41 and the crossbeam 4. The pre-installation blocks 41 at both ends of the crossbeam 4 slide against the side walls of the longitudinal beam 1, so that the crossbeam 4 is limited in all directions, thereby preventing the crossbeam 4 from falling off during the transportation of the frame assembly, thereby avoiding repeated assembly of the crossbeam 4 and affecting efficiency.

[0070] S3: Frame assembly welding: After the longitudinal beam 1, the anti-collision beam 3 and the cross beam 4 are assembled, a frame assembly is formed, and then the connection between the anti-collision beam 3, the cross beam 4 and the longitudinal beam 1 is welded.

[0071] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0072] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
