Description

Technical Field

[0001] The utility model relates to the technical field of vehicle production equipment, in particular to a skid. Background Art

[0002] Usually, the body-in-white of a car needs to be processed in a paint shop first (for example, using pre-treatment water washing, cathode electrophoresis, electrophoretic drying, painting and drying processes) before it can be transported to the final assembly shop for assembly.

[0003] Among them, the transportation of the body in white at each workstation in the paint shop is mainly achieved by skids. The existing skid designs are mostly designed for the same model, and there are also composite skid structures that take into account two models. In the actual research and development process, more new models are often developed on the existing models. Some new models may only be produced during the research and development period and will not be put on the market later, but these new models all need matching skids. When designing the skid, the existing skid structure is generally improved or re-developed to match the skid with the new model. This type of improvement or research and development cycle is long and the cost is high, which cannot meet the needs of continuous development of serial models.

[0048] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] The skid provided in the embodiment of the present application is used to transport the body-in-white between different workstations on a vehicle production line, especially in a paint shop, to facilitate corresponding treatment of the body-in-white, such as electrophoretic treatment or painting treatment.

[0050] For the convenience of description, a spatial rectangular coordinate system is constructed in this article, with the x-axis direction representing the lateral direction of the slide, that is, the width direction, the y-axis direction representing the longitudinal direction of the slide, that is, the length direction, and the z-axis direction representing the vertical direction of the slide, that is, the height direction; the directional words "upper" and "lower" refer to the relative position relationship in the z-axis direction, "inside" and "outside" refer to the relative position relationship in the x-axis direction, and "front" and "back" refer to the relative position relationship in the y-axis direction; in addition, expressions such as "first" and "second" are only used to distinguish one component with the same name from another, and do not indicate any primary and secondary relationship or front and back relationship between these components.

[0051] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of the structure of a skid provided in this application; Figure 2 for Figure 1 a front view of the skid shown; Figure 3 for Figure 2 Top view of the .

[0052] In this embodiment, the skid includes a base frame 10 and a rear support assembly 20, and the rear support assembly 20 is installed in the rear area of ​​the base frame 10. The front area and the rear area of ​​the base frame 10 are defined based on the conveying direction of the base frame 10 when conveying the body in white. In the illustrated orientation, the left side is the front area, and the right side is the rear area.

[0053] The rear support assembly 20 includes at least two rear support modules, each of which is arranged at intervals in the longitudinal direction of the base frame 10. Each rear support module includes at least one support portion, each support portion includes at least one positioning group for positioning the body-in-white, and the positioning group includes two positioning members arranged in the transverse direction of the base frame 10, and the two positioning members in the same positioning group are at the same height. Among them, the two positioning members in at least some positioning groups are arranged symmetrically relative to the longitudinal center line of the base frame 10.

[0054] It can be understood that the positioning group is used to position the body-in-white, and the relative position relationship between two positioning members in a positioning group is related to the type of the body-in-white being positioned.

[0055] It should be noted that when the body-in-white is positioned on the skid, two positioning points in the vehicle width direction, that is, in the lateral direction of the skid, are usually sufficient to meet the positioning needs, so a positioning group generally has two positioning members to meet the needs. Of course, according to actual application needs, each positioning member can also include multiple positioning structures, or a positioning group can have more than three positioning members.

[0056] The base frame 10 is also provided with at least one interface point 30, each interface point 30 includes two interface seats 31 (indicated at Figure 7 In the figure, two interface seats 31 are arranged horizontally along the base frame 10, and the interface seats 31 have mounting holes for mounting the rear support expansion module. Here, the structure of the rear support expansion module is consistent with that of the rear support module, and it is also a rear support module in essence, but it is not normally installed on the base frame 10, but can be selectively installed on the base frame depending on the actual vehicle model development situation. It is named as the rear support expansion module here only to distinguish it from the rear support module installed on the base frame 10.

[0057] In this embodiment, at least two rear support modules are arranged on the base frame 10 of the slide, and each rear support module is provided with at least one positioning group for positioning the body-in-white, so that the slide can match the body-in-white of at least two different models. At the same time, at least one interface point 30 is reserved on the base frame 10 to install the rear support expansion module, so that the slide can match more models. In the actual research and development and production of vehicles, when different new models are expanded on existing models, the existing slide can be used for matching, which can meet the rapid access of new models without redesigning the slide and conducting process verification, which is conducive to shortening the development cycle and reducing research and development costs.

[0058] In this embodiment, the base frame 10 includes two longitudinal beams 11 arranged in parallel and a plurality of transverse beams 12 connected between the two longitudinal beams 11. The number of the transverse beams 12 and the longitudinal arrangement positions of the base frame 10 can be determined as required to meet the structural strength of the base frame 10. The base frame 10 is a frame structure. In other embodiments, the base frame 10 can also be a plate structure, etc., provided that the related structural arrangements do not conflict.

[0059] The front end of the base frame 10 may be provided with a front stepping area 101, and the rear end of the base frame 10 may be provided with a rear stepping area 102. The front stepping area 101 and the rear stepping area 102 provide a standing space for the operator's operation, which is convenient for the operator to perform manual operations. In other embodiments, according to actual needs, the stepping area may also be provided only at the front end or the rear end of the base frame 10.

[0060] The base frame 10 may also be provided with pry stacking points 14. Specifically, a pair of pry stacking points 14 are provided near the front side of the base frame 10, and a pair of pry stacking points 14 are provided near the rear side of the base frame 10. The pry stacking points 14 are fixed on the longitudinal beam 11, and can be supported by vertically arranged columns. The pry stacking points 14 are provided so that multiple sleds can be stacked together when not in use to save space. It can be understood that the height and position setting of the pry stacking points 14 should meet the following requirements: the sled located above can be supported by the pry stacking points 14 of the sled below, and do not interfere with the structures on the upper and lower sleds.

[0061] In addition, a stacking positioning column 13 may be provided on the base frame 10 to position two upper and lower stacked sleds when multiple sleds are stacked. In the illustrated example, the stacking positioning column 13 is provided near the front step area 101. In other embodiments, the stacking positioning column 13 may be provided at other positions of the base frame 10 as long as it does not affect the normal use of other components on the sled.

[0062] The specific structural form and usage of the pry stacking point 14 and the stacking positioning column 13 can refer to the setting of the existing sliding skid, which is not the core of the utility model of this application and will not be described in detail here.

[0063] In an practicable solution, each support portion of the rear support module is provided with a pallet group, the pallet group includes two pallets, the two pallets are arranged along the lateral direction of the base frame 10, and at least one positioning group is provided on the pallet group. That is, the two positioning members of the same positioning group are respectively provided on the two pallets of a pallet group. The relative position relationship of the two pallets is related to the relative position relationship of the positioning members provided thereon, so as to facilitate the assembly of the two positioning members in the same positioning group. For example, when the two positioning members of a positioning group need to be arranged symmetrically relative to the longitudinal center line of the base frame 10, the two pallets of the pallet group on which the positioning group is installed are also arranged symmetrically relative to the longitudinal center line of the base frame 10, which is conducive to improving the accuracy of the installation position of the positioning member on the base frame 10.

[0064] The setting of the support plate can provide support for the body-in-white, and the setting of the positioning piece on the support plate limits the position of the body-in-white on the skid.

[0065] In a specific implementation, one support part may be provided with more than two positioning groups, and the two or more positioning groups are all mounted on one support plate group of the support part. In this case, at least one of the height position, positioning width, and longitudinal position of each positioning group on the base frame is different from each other. In this way, interference between different positioning groups can be avoided, ensuring that when one positioning group positions the white body matched with it, other positioning groups will not interfere with the white body.

[0066] Here, the positioning width of a positioning group refers to the lateral distance between two positioning members in one positioning group, that is, the distance between two positioning members in one positioning group in the x-axis direction.

[0067] In a specific implementation scheme, a detachable pad is provided on the pallets of some pallet groups, and the pad has an avoidance notch for avoiding the positioning piece on the pallet. When the pad is installed on the pallet, the positioning piece can extend out of the pad through the avoidance notch. With such a configuration, the support part can match at least two vehicle models at the pallet. The setting of the pad is equivalent to changing the height of the white body that can be supported on the sled. Therefore, for two vehicle models with the same positioning point but different supporting heights, the pad can be matched with the sled by setting or not setting the pad.

[0068] In a specific implementation manner, each rear support module may be provided with a mounting frame, and the rear support module may be mounted on the base frame 10 via the mounting frame.

[0069] In one practicable manner, the mounting frame may include two mounting vertical beams, and the two support plates of a support plate group of the rear support module may be respectively mounted on the two mounting vertical beams.

[0070] Specifically, the two mounting vertical beams may be connected by a mounting horizontal beam to improve the stability of the mounting frame.

[0071] In another achievable manner, the mounting frame may further include a mounting crossbeam, and two support plates of a support plate group of the rear support module may be respectively mounted on two ends of the mounting crossbeam.

[0072] Specifically, the mounting frame may further include other structures, such as a base portion for supporting the mounting crossbeam, or a transition beam structure for changing the position of the support plate.

[0073] The following is a detailed description of the skid structure in a specific application example with reference to the accompanying drawings. Figures 4 to 6 , Figure 4 for Figure 2 Side view of Figure 5 for Figure 2 Schematic diagram of the middle AA direction; Figure 6 for Figure 3 Schematic diagram of the middle BB direction.

[0074] In this embodiment, the rear support assembly 20 of the sled is provided with three rear support modules, which are respectively referred to as the first rear support module 21, the second rear support module 22 and the third rear support module 23 for the convenience of description. The first rear support module 21, the second rear support module 22 and the third rear support module 23 are sequentially arranged from front to back along the longitudinal direction of the base frame 10. The first rear support module 21 and the second rear support module 22 are arranged adjacent to each other, and there is a relatively large distance between the third rear support module 23 and the second rear support module 22. The interface point 30 for installing the rear support expansion module is arranged between the second rear support module 22 and the third rear support module 23.

[0075] In some other embodiments, the second rear support module 22 and the third rear support module 23 may be arranged adjacent to each other, and the interface point 30 for installing the rear support expansion module may be set between the first rear support module 21 and the second rear support module 22; in some other embodiments, more than two interface points 30 may be set, some of the interface points 30 may be arranged between the first rear support module 21 and the second rear support module 22, and some of the interface points 30 may be arranged between the second rear support module 22 and the third rear support module 23.

[0076] In practical applications, the number and arrangement of the rear support modules and the locations of the interface points 30 can be flexibly adjusted and are not limited to those described above.

[0077] The specific structures of the first rear supporting module 21 , the second rear supporting module 22 and the third rear supporting module 23 are described below with reference to the accompanying drawings.

[0078] Please refer to Figures 7 to 10 , Figure 7 for Figure 2 A partial enlarged view of the area where the first rear support module and the second rear support module are located; Figure 8 is a structural schematic diagram of a first rear support module in a specific embodiment; Fig. 9 is a structural schematic diagram of a second rear support module in a specific embodiment; Fig.10 for Figure 2 A partial enlarged view of the area where the first rear support module and the second rear support module are located.

[0079] In this embodiment, the first rear supporting module 21 includes three supporting portions, namely a first supporting portion 211 , a second supporting portion 212 and a third supporting portion 213 .

[0080] The support plate group of the first support portion 211 includes two first support plates 2111, and the two first support plates 2111 are symmetrically arranged relative to the longitudinal center line of the base frame 10; the first support portion 211 is provided with a positioning group, which includes two first positioning members 2112, and the two first positioning members 2112 are respectively fixed on the two first support plates 2111, and the two first positioning members 2112 are also symmetrically arranged relative to the longitudinal center line of the base frame 10.

[0081] In a specific implementation, a detachable pad 2113 may be provided on the first supporting plate 2111 of the first supporting portion 211 , so that the first supporting portion 211 can be matched with two types of vehicles.

[0082] The support plate group of the second support portion 212 includes two second support plates 2121, and the two second support plates 2121 are symmetrically arranged relative to the longitudinal center line of the base frame 10; the second support portion 212 is provided with a positioning group, which includes two second positioning members 2122, and the two second positioning members 2122 are respectively fixed on the two second support plates 2121, and the two second positioning members 2122 are also symmetrically arranged relative to the longitudinal center line of the base frame 10.

[0083] The support plate group of the third support part 213 includes two third support plates 2131, and the two third support plates 2131 are symmetrically arranged relative to the longitudinal center line of the base frame 10; the third support part 213 is provided with two positioning groups, the first positioning group includes two third positioning members 2132, the two third positioning members 2132 are respectively fixed on the two third support plates 2131, and the two third positioning members 2132 are also symmetrically arranged relative to the longitudinal center line of the base frame 10, and the second positioning group includes two fourth positioning members 2133, the two fourth positioning members 2133 are respectively fixed on the two third support plates 2131, and the two fourth positioning members 2133 are also symmetrically arranged relative to the longitudinal center line of the base frame 10. Figure 7 , Figure 8 and Fig.10 The positioning width of the first positioning group (two third positioning members 2132) of the third support portion 213 is greater than the positioning width of the second positioning group (two fourth positioning members 2133), and the first positioning group is arranged closer to the rear end of the base frame 10 relative to the second positioning group.

[0084] The first rear supporting module 21 is provided with a first mounting frame 214 , and the first supporting portion 211 , the second supporting portion 212 and the third supporting portion 213 are all mounted on the first mounting frame 214 and fixedly connected to the base frame 10 via the first mounting frame 214 .

[0085] The first mounting frame 214 includes a first mounting cross beam 2141, two first mounting vertical beams 2142 and two second mounting vertical beams 2143; the two ends of the first mounting cross beam 2141 are respectively fixedly connected to the two longitudinal beams 11 of the base frame 10; the two first mounting vertical beams 2142 are fixedly mounted on the upper end of the first mounting cross beam 2141, and are symmetrically arranged relative to the longitudinal center line of the base frame 10, the two first support plates 2111 of the aforementioned first supporting part 211 are respectively mounted on the two first mounting vertical beams 2142, and the two second support plates 2121 of the aforementioned second supporting part 212 are also respectively mounted on the two first mounting vertical beams 2142; the two second mounting vertical beams 2143 are fixedly mounted on the upper end of the first mounting cross beam 2141, and are symmetrically arranged relative to the longitudinal center line of the base frame 10, and the two third support plates 2131 of the aforementioned third supporting part 213 are respectively mounted on the two second mounting vertical beams 2143.

[0086] Combination Figure 7 , Figure 8 and Fig.10 , when arranged, the positioning group (two first positioning members 2112) of the first support part 211 is arranged near the front end of the base frame 10 relative to the positioning group (two second positioning members 2122) of the second support part 212, and is lower in height than the positioning group of the second support part 212; the height of the second support plate 2121 of the second support part 212 is substantially the same as the height of the third support plate 2131 of the third support part 213, and the longitudinal positions of the positioning group (two second positioning members 2122) of the second support part 212 and the second positioning group (two fourth positioning members 2133) of the third support part 213 on the base frame 10 are substantially the same, but the two second positioning members 2122 of the second support part 212 are arranged inward relative to the two fourth positioning members 2133 of the third support part 213, that is, the positioning width of the two second positioning members 2122 of the second support part 212 is smaller than the positioning width of the two fourth positioning members 2133 of the third support part 213. In this way, the four positioning groups of the three support parts of the first rear support module 21 do not interfere with each other.

[0087] As mentioned above, since the positioning width of the first positioning group (two third positioning members 2132) of the third support portion 213 is greater than the positioning width of the second positioning group (two fourth positioning members 2133), the positioning width of the first positioning group of the third support portion 213 is also greater than the positioning width of the positioning group of the second support portion 212. The third support plate 2131 of the third support portion 213 is closer to the outside of the base frame 10 relative to the second support plate 2121 of the second support portion 212. Accordingly, the second mounting vertical beam 2143 for mounting the third support portion 213 is arranged closer to the outside of the base frame 10 than the first mounting vertical beam 2142 for mounting the first support portion 211 and the second support portion 212.

[0088] In specific implementation, the first mounting frame 214 further includes two first base portions 2144, and the two ends of the first mounting beam 2141 are respectively fixed to the two longitudinal beams 11 of the base frame 10 through the two first base portions 2144. The height position of the first mounting beam 2141 can be adjusted through the first base portions 2144.

[0105] The third mounting frame 233 is different from the first mounting frame 214 or the second mounting frame 223 in that the third mounting frame 233 is not provided with a mounting cross beam, and includes two fourth mounting vertical beams 2331, which are arranged separately and respectively mounted on the two longitudinal beams 11 of the base frame 10. The support plate of the sixth supporting portion 231 and the support plate of the seventh supporting portion 232 are both mounted on the fourth mounting vertical beams 2331.

[0106] Combination Figure 5 , Fig.11 and Fig.12When arranged, the positioning group (two seventh positioning members 2312) of the sixth support portion 231 is arranged close to the front end of the base frame 10 relative to the positioning group (two eighth positioning members 2322) of the seventh support portion 232, and the positioning width of the positioning group of the sixth support portion 231 is smaller than the positioning width of the positioning group of the seventh support portion 232.

[0107] In order to avoid interference between the support plates of the sixth support part 231 and the seventh support part 232 during installation, the third mounting frame 233 is also provided with a transition beam structure, and the support plates of the sixth support part 231 and the seventh support part 232 are connected to the fourth mounting vertical beam 2331 through the transition beam structure.

[0108] Specifically, each fourth installation vertical beam 2331 is provided with a transition beam structure, and the transition beam structures of two fourth installation vertical beams 2331 are arranged identically.

[0109] Taking the fourth mounting vertical beam 2331 on one side as an example, its transition beam structure includes two first transition beams 2332 extending vertically, a second transition beam 2333 extending horizontally, and a third transition beam 2334 extending longitudinally; one end of the second transition beam 2333 is fixedly connected to the top end of the fourth mounting vertical beam 2331, and the other end thereof extends outwardly in the horizontal direction, the first first transition beam 2332 is fixedly connected to the outer end of the second transition beam 2333, and the seventh support plate 2321 of the seventh support portion 232 is fixed on the first first transition beam 2332; one end of the third transition beam 2334 is fixedly connected to the second transition beam 2333, and the other end thereof extends forward in the longitudinal direction, the second first transition beam 2332 is fixedly connected to the front end of the third transition beam 2334, and the sixth support plate 2311 of the sixth support portion 231 is fixed on the second first transition beam 2332.

[0111] In actual applications, the structure of the third mounting frame 233 may also be adjusted in various ways according to the needs of the support portion mounted thereon, which will not be described one by one.

[0112] For each of the aforementioned mounting frames, a reinforcing plate 201 may be provided as required to improve the structural stability thereof.

[0113] The structural form of the positioning members in the aforementioned positioning groups can be determined according to the needs of the respective matching vehicle models. For example, the first positioning member 2112, the second positioning member 2122, the third positioning member 2132, the fourth positioning member 2133, the fifth positioning member 2212, the sixth positioning member 2222 and the eighth positioning member 2322 are all block structures, and the seventh positioning member 2312 is a columnar structure.

[0114] Generally speaking, each positioning group matches one vehicle model. However, in actual applications, one positioning group can also match two vehicle models.

[0115] Taking the positioning member of the positioning group as a positioning block as an example, the positioning group has two positioning surface groups. Among them, the first positioning surface group includes two first positioning surface parts 1a of the two positioning blocks facing each other, and a bottom of a body-in-white 2a is provided with two positioning groove structures in the vehicle width direction. The two groove structures of the body-in-white 2a are respectively abutted against the two first positioning surface parts 1a for positioning, that is, after the positioning block extends into the groove structure of the body-in-white 2a, the first positioning surface part 1a located on the outside abuts against the groove structure near the outer groove side wall to limit the position, such as Fig.13 The second positioning surface group includes two second positioning surface parts 1b of two positioning blocks facing each other, and the bottom of another body-in-white 2b is also provided with two positioning groove structures in the vehicle width direction, and the two groove structures of the body-in-white 2b are respectively abutted against the two second positioning surface parts 2b for positioning, that is, after the positioning block extends into the groove structure of the body-in-white 2b, the second positioning surface part 1b located on the inner side abuts against the groove side wall of the groove structure close to the inner side for limiting position.

[0116] In a specific application, the fourth positioning member 2133 provided on the third supporting portion 213 of the first rear supporting module 21 can be provided with a structure having two positioning surface groups. Figures 1 to 12 The skid shown can match at least ten types of vehicle models. Specifically, the first support portion 211 can match the first type of vehicle model and the second type of vehicle model when the pad 2113 is provided and when the pad 2113 is not provided, respectively, the second positioning member 2122 of the second support portion 212 can match the third type of vehicle model, the third positioning member 2132 of the third support portion 213 can match the fourth type of vehicle model, the fourth positioning member 2133 of the third support portion 213 can match the fifth and sixth types of vehicle models, the fifth positioning member 2212 of the fourth support portion 221 can match the seventh type of vehicle model, the sixth positioning member 2222 of the fifth support portion 222 can match the eighth type of vehicle model, the seventh positioning member 2312 of the sixth support portion 231 can match the ninth type of vehicle model, and the eighth positioning member 2322 of the seventh support portion 232 can match the tenth type of vehicle model.

[0117] The above description is merely an exemplary description. In actual applications, the slide can be matched with different types of vehicle models according to different designs of different supporting parts.

[0118] In the description of the above specific embodiment, only the two sixth positioning members 2222 of the fifth bracket 222 are arranged asymmetrically relative to the longitudinal center line of the base frame 10, and the two positioning members of the remaining positioning groups are arranged symmetrically relative to the longitudinal center line of the base frame 10. In actual applications, whether the positioning group is arranged symmetrically relative to the longitudinal center line of the base frame 10 depends on the matching vehicle model and can be flexibly adjusted, and no further examples are given.

[0119] In specific applications, the sled provided by the present application can be used as a topcoat sled or as an electrophoresis sled, and the corresponding treatment processes for the white body are different. The example shown in the figure is an electrophoresis sled. When the sled is used as an electrophoresis sled, it also includes at least two locking modules installed in the front area of ​​the base frame 10, each locking module includes two locking parts arranged along the transverse direction of the base frame 10 and symmetrically arranged relative to the longitudinal center line of the base frame 10, and the locking width of each locking module is different. The locking width here refers to the lateral distance between the two locking parts of a locking module, that is, the distance between the two locking parts of a locking module in the x-axis direction.

[0120] In the illustrated example, the slide is provided with two locking modules, namely a first locking module 40 and a second locking module 50. Figure 3 As shown, the first locking module 40 is arranged near the front end of the base frame 10 relative to the second locking module 50, and the locking width of the first locking module 40 is smaller than the locking width of the second locking module 50. In this way, the locking module can be used to lock and fix the body in white during the electrophoresis process. The arrangement of different locking modules can meet the locking requirements of different vehicle widths.

[0121] Among them, the specific structure and locking method of the locking module can be implemented by referring to the existing technology. The specific structure and locking method of the locking module are not the core of the utility model of this application and will not be described in detail here.

[0122] When the sled is used as a topcoat sled, no locking module is provided, and the rest of the structure is the same as that of the electrophoresis sled.

[0123] In practical applications, the sled may be provided with a lug plate 15 in the middle of the base frame 10 to facilitate hoisting operations of the sled. Specifically, a mark (such as a coding form, etc.) may be provided on the lug plate 15 to facilitate identification of the sled, which is beneficial to the automated operation of the production line.

[0124] In actual application, the sled is provided with a swing rod front hanging point 60 on the front side of the base frame 10 and a swing rod rear hanging point 70 on the rear side, so as to facilitate the sled to be connected and disconnected with the conveying swing rod conveying mechanism during transportation. The specific structural forms of the swing rod front hanging point 60 and the swing rod rear hanging point 70 can also be realized based on existing technologies.

[0125] The above is a detailed introduction to the skid provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
