AI Technical Summary
RPS点所处的面非绝对平面，定位稳定性有限，因此需要增加D1、D2基准孔以提高X、Y向的定位精确性，由于检具是车身位置坐标，受翼子板整体刚性和重力的影响较大，加上零件内应力的释放，导致基准面的回弹较明显，原检具基准与零件基准面贴合的情况下，相对位置关系发生了变化，以此种状态定位完成的零件测量分数较低，精度数据出现失真情况；
[0017]本实用新型设计的检测装置，其未改变检测装置整体结构，在RPS点A1两侧增设两组辅助检具体，且所述辅助检具体分布于所述RPS点A1两侧，移除了在RPS点A1位置的检具体，该检测装置整改难度低，有效地节约了制造成本，同时也解决了传统车身覆盖件复杂零件检测基准误差对模具调试的影响，有效缩短零件调试周期，且冲压件在改造后的检测装置上状态稳定，合格率高。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle body panel stamping technology, and in particular to a vehicle body panel stamping debugging and testing device. Background Technology
[0002] Complex automotive body panel parts are difficult to control due to their complex shapes and insufficient rigidity. The part inspection system based on the body position is inconsistent with the die stamping state and is also affected by gravity.
[0003] Taking the fender, a complex automotive body panel component that is difficult to position, as an example, see Appendix Figure 1a , 1b As shown, the part is constrained in the Y direction by 4 RPS points (A), in the X direction by 2 RPS points (B), and in the Z direction by 3 RPS points (C). The surface where the RPS points are located is not an absolute plane, and the positioning stability is limited. Therefore, it is necessary to add reference holes D1 and D2 to improve the positioning accuracy in the X and Y directions. Since the fixture is the vehicle body position coordinate, it is greatly affected by the overall rigidity of the fender and gravity. In addition, the release of internal stress in the part leads to obvious springback of the reference surface. When the original fixture reference and the part reference surface are in contact, the relative positional relationship changes. The part measurement score completed under this state is low, and the accuracy data is distorted.
[0004] Therefore, based on the above problems, how to modify the existing inspection tools in a way that saves both costs and time has become an important technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a vehicle body panel stamping debugging and testing device that is easy to rectify and has low manufacturing cost.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] The vehicle body panel stamping, testing, and inspection device disclosed in this utility model includes:
[0008] A substrate, a conformal detection base block fixed on the substrate for conformal support of the stamped part, wherein the substrate is fixed with detection components at RPS points A2, A3, and A4; and further includes...
[0009] The auxiliary inspection objects are fixedly connected at intervals between RPS point A1, RPS point A2, and RPS point A3, and the auxiliary inspection objects are distributed on both sides of RPS point A1.
[0010] Furthermore, both the inspection body and the auxiliary inspection body include a column and a clamp, with the clamp fixed to the base plate via the column.
[0011] Furthermore, the clamp is a vertical clamp.
[0012] Furthermore, the distance between RPS point A1 and RPS point A2 is smaller than the distance between RPS point A1 and RPS point A3.
[0013] Furthermore, the contour detection base block is located outside the RPS points A1 and A3 and is fixedly connected to a limiting post, the limiting post corresponding to the specific position of the auxiliary detection.
[0014] Furthermore, the inspection unit includes a first inspection unit, a second inspection unit, and a third inspection unit;
[0015] The substrate is fixedly connected to a first detection unit and a third detection unit inside the contour detection base block, and the substrate is fixedly connected to a second detection unit outside the contour detection base block.
[0016] In the above technical solution, the vehicle body panel stamping and testing device provided by this utility model has the following advantages:
[0017] The detection device designed in this utility model does not change the overall structure of the detection device. Two sets of auxiliary inspection bodies are added on both sides of RPS point A1, and the auxiliary inspection bodies are distributed on both sides of RPS point A1. The inspection body at the RPS point A1 position is removed. The detection device is easy to modify and effectively saves manufacturing costs. At the same time, it solves the problem of the influence of the traditional body panel complex part detection benchmark error on mold debugging, effectively shortens the part debugging cycle, and the stamped parts are stable on the modified detection device with a high pass rate.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] See Figure 1;
[0027] A utility model body panel stamping debugging and testing device includes: a base plate 1, a contour detection base block 2, a testing body 3, an auxiliary testing body 4; a limiting post 5; and a vertical clamping device 6.
[0028] The conformal detection base block 2 is fixed on the base plate 1 for conformal support of the stamped part 7, which is a fender in the prior art. The base plate 1 has detection bodies 3 fixedly connected to the conformal detection base block 2 at RPS points A2, A3 and A4. At least three auxiliary detection bodies 4 are fixedly connected at intervals between RPS points A1 and RPS points A2 and A3, and the auxiliary detection bodies 4 are distributed on both sides of RPS point A1.
[0029] The inspection device removed the inspection body at RPS point A1 and added two sets of at least six auxiliary inspection bodies 4 on both sides of RPS point A1. This enabled the application of six mold debugging and inspection benchmark systems without changing the overall structure of the inspection device. The modification was simple and effectively saved manufacturing costs. It also solved the problem of the influence of the traditional complex parts inspection benchmark error on mold debugging. By adding the debugging and inspection benchmark technology, the parts debugging cycle can be shortened by more than 13%. The stamped part 7 was stable on the modified inspection device and the first inspection pass rate exceeded 85%.

[0031] Preferably, the distance between RPS point A1 and RPS point A2 is smaller than the distance between RPS point A1 and RPS point A3. The distance between RPS point A1 and RPS point A2 is the side door side, and the distance between RPS point A1 and RPS point A3 is the engine hood overlap side. The contour detection base block 2 is located outside RPS point A1 and RPS point A3 and is fixedly connected to the limiting post 5. The limiting post 5 corresponds to the position of the auxiliary detection body 4.
[0032] Preferably, inspection item 3 includes a first inspection item 3, a second inspection item 3, and a third inspection item 3;
[0033] The substrate 1 is fixedly connected to the first inspection unit 3 and the third inspection unit 3 inside the contour detection base block 2, and the substrate 1 is fixedly connected to the second inspection unit 3 outside the contour detection base block 2.
[0034] In the above technical solution, the body panel stamping debugging and testing device provided by this utility model adds the application of two sets of mold debugging and testing benchmark systems. This new debugging and testing benchmark application is generated by optimization without changing the traditional structure of conventional inspection tools, which effectively reduces the difficulty of rectification and manufacturing cost.
