Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing final assembly production line, in particular to an auxiliary supporting tooling for an automobile final assembly collinear production line and a collinear production line. Background Art

[0002] At present, most OEMs generally adopt the method of assembling multiple models on the same production line, that is, the final assembly of multiple models can be completed on the same production line. In this way, there is no need to install different production lines according to different models, which can greatly reduce the cost of the production line.

[0003] However, although the existing co-production line can adapt to different models, there are still certain restrictions on the models, that is, the models produced on the co-production line need to have the same chassis structure to match the skids on the production line for production. Models with different chassis structures still cannot use the same assembly line. For example, the existing production line is a non-load-bearing body, and the market needs to add a new car with a load-bearing body and a different chassis structure. The platform of the existing production line cannot meet the needs of the new model assembly conveyor line. Utility Model Content

[0004] The main purpose of the utility model is to provide an auxiliary support tooling for an automobile final assembly co-line production line, which can meet the final assembly line transmission requirements of automobile bodies with different structures, further improve the adaptability of the production line to the body chassis structure and reduce costs.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, an auxiliary support tooling for a common production line of automobile assembly is provided, comprising a pair of mutually symmetrical connecting support structures, the connecting support structures being connected and fixed by connecting ribs, the connecting support structures being used to connect the front support points of the slide and support the bottom of the vehicle body.

[0006] After adding the co-linear auxiliary support tooling, the co-linear auxiliary support tooling replaces the connection between the vehicle and the skid. When changing to a different chassis model, only the structure of the co-linear auxiliary support tooling needs to be changed, and a new production line that adapts to the new chassis model must be built, which can reduce costs.

[0007] As a further improvement, the structure of the connecting support structure includes a gate-shaped connecting member fixed on one side of the connecting rib.

[0008] As a further improvement, the door-shaped connecting piece has upper and lower through holes and is equipped with connecting pins for connecting and fixing the bottom cross beam of the vehicle body.

[0009] As a further improvement, the connecting support structure has a reinforcing rib inclined upward, the end of the reinforcing rib is fixed to the upper plate, and the upper plate has a pin hole.

[0010] As a further improvement, the reinforcing ribs and the upper plate are arranged on opposite sides of the door-shaped connecting piece; the upper plate, the reinforcing ribs and the door-shaped connecting piece together form a Z-shaped structure as the connecting support structure.

[0011] As a further improvement, the door-shaped connecting piece is a steel plate structure.

[0012] The second aspect of the utility model provides a common production line for automobile final assembly, including the above-mentioned auxiliary support tooling for the common production line for automobile final assembly.

[0013] The application of the technical solution of the utility model has the following technical effects:

[0014] By connecting the co-linear auxiliary support tooling with the slide at the supporting point, the co-linear production line that was originally only capable of assembling one type of chassis structure can also be used to assemble models with other chassis structures. It is no longer necessary to build a new production line for the molding of the chassis structure of new models, thereby improving the adaptability of the production line to the body chassis structure and reducing costs.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Example 1

[0036] The schematic diagram of the existing A-type vehicle on the skid is as follows Figure 1-2 As shown, the existing skid has a front support point 11, a middle support point 12, and a rear support point 13. The front support point is currently supported by a positioning pin, which is compatible with the positioning hole h1 of the chassis of the A-type vehicle body. However, the chassis of the new model B-type vehicle to be produced does not have a positioning hole corresponding to the front support point 11, so that the B-type vehicle cannot be transported and assembled using the existing co-line production line.

[0037] The auxiliary support tooling for the automobile assembly line provided in this embodiment can be added to the bottom of the body of Model B before Model B goes on the production line. After adding the auxiliary support tooling for the automobile assembly line, the bottom of the body of Model B has the same positioning points as Model A through the tooling, so that Model B can be transported and assembled using the existing co-line production line.

[0038] like Figure 3-4As shown, the auxiliary support tooling of the automobile assembly line is composed of a pair of mutually symmetrical connecting support structures 2, and the connecting support structures 2 are connected and fixed by connecting ribs 3. The structure of the connecting support structure 2 includes a door-shaped connecting member 21. The door-shaped connecting member 21 is a steel plate structure, which is fixed on one side of the connecting rib 3. The door-shaped connecting member 21 has upper and lower through holes and is equipped with a connecting pin 22, which is used to connect and fix the bottom cross beam of the B-type car body. The connecting support structure 2 has an upwardly inclined reinforcing rib 23, and the end of the reinforcing rib 23 is fixed to the upper plate 24. The upper plate 24 has a pin hole h2, and the pin hole h2 cooperates with the locating pin of the front support point 11. That is, during installation, the pin hole h2 is used to replace the locating hole h1 of the chassis of the A-type body to cooperate with the front support point 11 of the skid.

[0039] The reinforcing ribs 23 and the upper plate 24 are arranged on the opposite side of the door-shaped connecting member 21. The upper plate 24, the reinforcing ribs 23 and the door-shaped connecting member 21 together present a Z-shaped structure, which serves as a connecting support structure 2 to connect the front support point of the skid and support the vehicle body through the door-shaped connecting member 21. Figure 5 The diagram shows the cooperation between the connecting support structure 2 and the bottom of the vehicle body.

[0040] Usage process:

[0041] Before the B-type car is put into assembly, the connecting pins 22 on the left and right sides of the collinear auxiliary support tooling are passed through the holes of the door-shaped connecting piece 21 and connected and fixed with the holes of the bottom beam of the B-type car, so that the collinear auxiliary support tooling is fixed to the bottom of the B-type car.

[0042] When the B-type vehicle is transported, the collinear auxiliary support tooling connected to its bottom falls into the positioning pin of the front support point 11 of the sled, and the longitudinal beams on both sides are supported by the middle support point 12 and the rear support point 13 of the sled; the front, middle and rear support points of the sled can be connected to the B-type vehicle. Figure 6 shown.

[0043] After the assembly of the Type B vehicle is completed, the collinear auxiliary support tooling will be removed and installed to the bottom of the Type B vehicle before being put back on line. The collinear auxiliary support tooling can be recycled.

[0044] It can be seen that, through the co-linear auxiliary support tooling provided in this embodiment, the co-linear production line that was originally only capable of assembling chassis structures of type A vehicles can also be capable of assembling vehicles with chassis structures of type B vehicles. It is no longer necessary to build a new production line for the assembly of chassis structures of type B vehicles, thereby improving the adaptability of the production line to the vehicle body chassis structure and reducing costs.

[0045] This embodiment uses the front support point as an example to replace the connection between the bottom of the vehicle and the skid with a collinear auxiliary support tooling to provide adaptability of the collinear production line. In fact, when the structure of other parts of the bottom of the new model is improved, similar auxiliary support tooling can also be set for alternative connection to adapt to models with different chassis structures.

[0046] Example 2

[0047] The second embodiment of the present invention provides a common production line for automobile final assembly, which is equipped with the auxiliary support tooling in the first embodiment.

[0048] Due to the provision of the above-mentioned auxiliary support tooling, the technical effect of utilizing the auxiliary support tooling in Example 1 is achieved. It is no longer necessary to build a new production line for the assembly of the chassis structure of the B-type vehicle, thereby improving the adaptability of the production line to the vehicle body chassis structure and reducing costs. The above is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model shall be included in the scope of protection of the utility model.
