[0029] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0030] To facilitate understanding of the technical solutions and technical effects of the embodiments of the present utility model, the prior art of the present utility model will be briefly described below.
[0031] With the development of the vehicle industry, lightweight design and improvement of body strength have become key requirements. In this trend, many components on the vehicle body have been changed from traditional steel parts to cast aluminum parts.
[0032] If the parts are made of steel, during the manufacturing of steel parts, an online punching process is usually adopted to punch precise positioning holes on the steel parts to improve the accuracy of the positioning holes. However, if parts such as the front hood and fenders are made of cast aluminum, the same online punching process cannot be used to improve the accuracy of the positioning holes during the manufacturing of cast aluminum parts, resulting in the inability to control the accuracy of the positioning holes on the cast aluminum parts. Among them, the positioning holes can be assembly positioning holes.
[0033] If an attempt is made to adopt the online punching process on cast aluminum parts, the following problems will be encountered:
[0034] 1) Since the ductility of aluminum is lower than that of steel and the plastic deformation ability of aluminum is poor, cracks or fractures are likely to occur during the punching process of cast aluminum parts.
[0035] 2) Since the hardness of aluminum alloy is relatively soft, surface scratches or depressions are likely to occur during the punching process of cast aluminum parts.
[0036] 3) Aluminum alloy can be used to manufacture the cylinder block components of the engine through die-casting process. The head cover part of the cylinder block occupies a relatively large space due to design requirements and its structure is relatively complex. Due to the complex structure and large space occupation of the head cover, problems such as difficult positioning, uneven distribution of punching pressure, easy deformation or damage may occur during the online punching operation of the head cover, facing more technical challenges.
[0037] If parts such as the front hood, fenders, front-end module, and headlamps of the vehicle body are made of cast aluminum and the accuracy of the assembly positioning holes of the cast aluminum parts is low, this will affect the assembly accuracy of the parts. Since the front hood and fenders of the vehicle body are both located at the front of the vehicle, the poor assembly accuracy of the front hood, fenders, front-end module, and headlamps will make it difficult for the front part of the whole vehicle to meet the design standards, increasing the repair time and cost of the vehicle and affecting the user's sensory experience of the vehicle. The design standards can include DTS (Dimensional Tolerance Standard) targets.
[0038] If the accuracy of the assembly positioning holes of the vehicle body cast aluminum parts is low, a multi-layer sliding centering assembly tooling can be adopted for the assembly of cast aluminum parts to reduce the assembly deviation caused by insufficient accuracy of the assembly positioning holes. However, the structure of this assembly tooling is complex, the volume is large, the weight is relatively heavy, and the operation of this assembly tooling is difficult, thus affecting the improvement of the production capacity rhythm. The production capacity rhythm refers to the time required for the production line to complete a product unit. The left / right positioning points X and Y direction accuracy of the assembly tooling on the vehicle body cast aluminum parts needs to be controlled within the range of ±1.2 mm, that is, the assembly tooling needs to ensure that its left / right direction positioning accuracy is within the range of ±1.2 mm to ensure that the cast aluminum parts can be accurately installed in the predetermined position.
[0039] Refer to Figure 1, showing a schematic diagram of a positioning structure provided in an embodiment of the present invention for vehicle assembly, applied to a vehicle, the vehicle having at least one component to be assembled; the area on the vehicle for assembling the positioning structure is the positioning structure assembly area; the positioning structure includes a skeleton and an assembly positioning member with positioning holes;
[0040] The skeleton is fixed on the positioning structure assembly area; at least one positioning member placement hole is provided on the skeleton;
[0041] The assembly positioning member is located in the positioning member placement hole, and the assembly positioning member is connected to the skeleton; the assembly positioning member is used to determine the assembly position of the component.
[0042] In an embodiment of the present invention, the vehicle has at least one component to be assembled. The components can be shock towers, fenders, front hoods, etc. of the vehicle. If the components of the vehicle are cast aluminum parts, the online punching process cannot be used to improve the accuracy of the assembly positioning holes on the cast aluminum parts. The components can be assembled on the vehicle body skeleton through the positioning structure. The area on the vehicle body skeleton for assembling the positioning structure is the positioning structure assembly area.
[0043] In an embodiment of the present invention, the positioning structure for assembling components of a vehicle includes a skeleton and an assembly positioning member with positioning holes. At least one positioning member placement hole is provided on the skeleton. The assembly positioning member of the positioning structure is located in the positioning member placement hole, and the assembly positioning member is connected to the skeleton. The assembly positioning member can determine the assembly position of the component. In an embodiment of the present invention, the positioning hole of the assembly positioning member of the positioning structure can be used as the assembly positioning hole on the cast aluminum part to install the component, that is, the positioning hole of the assembly positioning member is used instead of the assembly positioning hole of the cast aluminum part. The positioning hole can be a hole with a diameter of φ22mm (22 millimeters). The positioning hole on the assembly positioning member can be used as the fixture positioning hole for the component to be assembled onto the vehicle body skeleton. By using this assembly positioning member, it can be ensured that the assembly position of the component on the vehicle body skeleton is accurate.
[0044] As an example of the present invention, Figure 1 the positioning structure in includes a skeleton and an assembly positioning member with positioning holes. At least one positioning member placement hole is provided on the skeleton. The assembly positioning member of the positioning structure is located in the positioning member placement hole, and the assembly positioning member is connected to the skeleton.
[0045] In the embodiment of the present utility model, the shape of the framework of the positioning structure may match the shape of the positioning structure assembly area of the vehicle body framework. Alternatively, the shape of the framework of the positioning structure can ensure that the framework of the positioning structure can be fixed in the positioning structure assembly area through a connecting bracket, etc., and the shape of the area on the positioning structure assembly area that contacts the positioning member placement hole of the framework matches the shape of the positioning member placement hole. The framework is fixed on the positioning structure assembly area of the vehicle body framework. It should be noted that since the shape of the framework of the positioning structure may match the shape of the positioning structure assembly area of the vehicle body framework, or the shape of the framework of the positioning structure ensures that the framework of the positioning structure can be fixed in the positioning structure assembly area through a connecting bracket, and the shape of the area on the positioning structure assembly area that contacts the positioning member placement hole of the framework matches the shape of the positioning member placement hole, the positioning structure is a general structure and can be applied to different vehicle models, different vehicle body frameworks, and can be used for the installation of different components.
[0046] Referring to Figure 2 , a schematic diagram showing a positioning structure fixed in a positioning structure assembly area provided in the embodiment of the present utility model is shown. Figure 2 The component in is the front face of the vehicle. The front face of a vehicle generally includes a front hood, a front bumper, a grille, headlights, turn signals, etc. The framework of the positioning structure is L-shaped. The shape of the framework of the positioning structure can ensure that the framework of the positioning structure can be fixed in the positioning structure assembly area through a connecting bracket, and the shape of the area on the positioning structure assembly area that contacts the positioning member placement hole of the framework matches the shape of the positioning member placement hole. The positioning structure is provided with mounting through holes, and the positioning structure assembly area is provided with mounting points, also known as mounting holes. Connecting bolts pass through the mounting through holes and the mounting holes to fix the framework of the positioning structure on the positioning structure assembly area of the vehicle body framework.

The positioning structure of the present utility model can be applicable to various vehicle models, effectively reducing the manufacturing cost of the vehicle, optimizing the vehicle design process, and facilitating the production management of the vehicle. The positioning structure of the present utility model does not match the component in the X / Y direction, thereby reducing the precision error of the assembly positioning member and the positioning holes on the assembly positioning member caused by the deviation of the component. The present utility model uses the positioning holes of the assembly positioning member of the positioning structure as the assembly positioning holes on the cast aluminum part to install the component, that is, uses the positioning holes of the assembly positioning member to replace the assembly positioning holes of the cast aluminum part, which can improve the precision of the assembly positioning holes of the cast aluminum part to within the range of ±0.5 mm, effectively solving the problem that it is difficult to control the precision of the assembly positioning holes of the cast aluminum part and significantly improving the precision of the assembly positioning holes.
