Detailed Description

For the purposes of brevity and explanation, the principles of the present application are described herein with reference primarily to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of adaptive positioning reference devices and that these same or similar principles may be implemented therein, with any such variations not departing from the true spirit and scope of the present patent application. Moreover, in the following description, reference is made to the accompanying drawings that show specific exemplary embodiments. Changes may be made in these embodiments without departing from the spirit and scope of the application. In addition, while a feature of the present application may have been disclosed with respect to only one of several implementations/embodiments, such feature may be combined with one or more other features of the other implementations/embodiments as may be desired and/or advantageous for any given or identified function. The following description is, therefore, not to be taken in a limiting sense, and the scope of the present application is defined by the appended claims and their equivalents.

It should be noted here that the inner side in the direction of lateral positioning of the vehicle body in the present application means that the direction of lateral positioning of the vehicle body is directed toward the vehicle body, and conversely, the outer side in the direction of lateral positioning of the vehicle body means that the direction of lateral positioning of the vehicle body is directed away from the vehicle body.

Fig. 1 illustrates a vehicle body assembly system including a vehicle body 6. As can be seen from fig. 1, the vehicle body assembly tooling system exemplarily comprises a bottom tooling frame 1 and a side tooling frame 2, wherein, as can be seen from fig. 1, the bottom tooling frame 1 is installed at the lower end of a vehicle floor to support and position the vehicle floor; and the side wall tooling frame 2 is arranged on the outer side of the side wall of the vehicle body and used for supporting and positioning the side wall of the vehicle body. In addition, as can also be seen from fig. 1, the bottom tooling frame and the side wall tooling frame form two intersecting surfaces, and a locking device 3 is arranged at the intersecting position of the two surfaces to lock the bottom tooling frame 1 and the side wall tooling frame 2.

In addition, as can be seen from fig. 1 and fig. 2, the vehicle body total assembling tooling system related to the present application is further provided with a positioning reference device at the side wall tooling frame. Among these positioning reference devices, there are an adaptive positioning reference device 5 and a fixed positioning reference device 4. It should be explained that the positioning reference of the vehicle body assembly tool is generally calibrated at a nominal position, and if the dimension of the vehicle body in the width direction is larger, the reference at the nominal position interferes with a wider partial area. The interfering part is related to the shape of the vehicle bottom plate, and the region where the vehicle bottom plate is intersected into a whole along the width direction is the region where the self-adaptive reference needs to be arranged, and the regions exemplarily comprise a side wall and bottom plate front door hinge pillar contact region, a bottom plate door sill contact region and a rear bottom plate assembly contact region. Here, as can be seen from fig. 2, the adaptive positioning reference device 5 is mainly disposed at the matching region of the floor front door hinge pillar and the vehicle body side wall, the matching region of the floor sill and the vehicle body side wall, and the matching region of the rear floor assembly and the vehicle body side wall. The arrangement mode ensures that the key position of the body side of the automobile body in the width direction can not be subjected to excessive extrusion force to cause dimension error of the whole automobile body in the width direction. Furthermore, it can be seen that a plurality of fixed positioning reference devices are arranged above the adaptive positioning reference device. The method realizes that the datum of the fixed positioning datum device is not influenced and still keeps at the calibrated datum position when the datum of the self-adaptive positioning datum device moves, thereby ensuring the dimensional accuracy of the upper part of the vehicle body and effectively reducing the dimensional deviation of the vehicle body.

Fig. 3 schematically shows an adaptive positioning reference device 5 according to the present disclosure. As can be seen from fig. 3, the adaptive positioning reference device 5 includes a reference 5-3 which is arranged on the outside of the side body in the direction in which the vehicle body is positioned laterally and which positions the side body laterally. The reference 5-3 can be made of any material having sufficient support strength to support and position the body side. The self-adaptive positioning reference device further comprises a collapsing mechanism 5-2, wherein the collapsing mechanism 5-2 is arranged outside the reference 5-3 along the lateral positioning direction of the vehicle body, and can drive the reference to retract when extrusion force acts on the reference. Exemplarily, as can be seen from fig. 3, the collapsing mechanism 5-2 can be configured as a cylinder which can push the reference back and forth in the direction of the lateral positioning of the vehicle body in case of a force. In addition, the self-adaptive positioning reference device also comprises a stop element 5-5 which is arranged on the inner side of the crumple mechanism 5-2 along the direction of lateral positioning of the vehicle body and is used for limiting the stroke of the crumple mechanism towards the side wall of the vehicle body. In this case, the stop element can be designed as a stop block as shown in fig. 3.

In particular, the pre-set stop block 5-5 is able to determine the nominal position of the reference 5-3 in the adaptive positioning reference device. When the stroke of the collapsing mechanism 5-2, namely the cylinder, is limited by the stop block, the reference is calibrated at a nominal position, so that the initial dimensional accuracy of the positioning in the width direction of the vehicle body is ensured. Further, when the width direction dimension of the vehicle body is larger than the initially specified dimension, a squeeze occurs between the vehicle body and the reference 5-3. Under the action of the extrusion force, the cylinder 5-2 drives the datum 5-3 to retract, so that the larger extrusion force of the vehicle body acting on the datum is converted into the micro thrust of the cylinder. The micro thrust will act on the body side wall tooling frame 2, and the frame will not be inclined outwards. Meanwhile, the fixed reference group fixed on the body side wall tooling frame is still kept at the accurately positioned position.

Furthermore, as can also be seen from fig. 3, the adaptive positioning reference device 5 further comprises a support means 5-1, which is configured here as a support base 5-1. The supporting seat 5-1 is arranged outside the cylinder 5-2 along the lateral positioning direction of the vehicle body, and supports and fixes the self-adaptive positioning reference device at the side wall tooling frame 2 of the vehicle body.

Additionally, the adaptive positioning reference device according to the present disclosure further comprises a clamping device. As can be seen from fig. 3, the clamping mechanism is arranged inside the datum in the direction of lateral positioning of the vehicle body for clamping the underbody panel and the side body panel in cooperation with the datum. Optionally, the clamping mechanism comprises a collet 5-4 and a drive element 5-6 for driving the collet.

The above examples mainly illustrate the adaptive positioning reference device of the present application. Although only a few embodiments of the present application have been described, those skilled in the art will appreciate that the present application may be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and various modifications and substitutions may be made therein without departing from the spirit and scope of the present application as defined in the appended claims.
