[0002] Figure 1 The figure shows the assembly structure of the top cover 2, the side panel 1 and the top cover trim 4 of the automobile. When the top cover trim 4 is assembled on the automobile, the top cover trim 4 is prone to warping. The warping is mainly due to two reasons. On the one hand, the top cover trim flange 41 is interference-connected with the top cover 2 and the side panel 1. If the size of the interference fit is unstable, the top cover trim 4 is prone to distortion, resulting in improper assembly. On the other hand, the first distance L1 between the hypotenuse of the top cover 2 and the top cover flange 21 is not greatly affected by welding, so the first reaction force F1 is relatively stable, but the second distance L2 between the hypotenuse of the side panel 1 and the top cover flange 21 is affected by the welding accuracy, so the generated second reaction force F2 is large or small, and it is easy for the actual distance to differ greatly from the design parameters; when the second distance L2 is small, the second reaction force F2 will cause the top cover trim 4 to flip over, resulting in warping of the top cover trim 4; when the second distance L2 is large, the interference fit of the top cover trim 4 is prone to be unreliable.

[0003] In the prior art, the spacing is calculated by three-coordinate detection, which is complex and has a long cycle.

[0040] According to a first aspect of the present invention, a testing tool for automobile production is provided, which includes a testing body 100 .

[0041] Hereinafter, the specific structures of the above-mentioned components of the checking jig for automobile production according to the present embodiment will be described.

[0042] In this embodiment, if Figure 1 and Figure 3 As shown, the automobile production inspection fixture is used to detect the dimensions of the side panel 1 and the top cover 2 of the automobile after assembly, wherein the side panel 1 is arranged on the side of the white body, the top cover 2 is arranged on the top of the white body, the top edge of the side panel 1 is welded to the side edge of the top cover 2, the connection between the side panel 1 and the top cover 2 forms a receiving groove 3, the top cover trim 4 is installed in the receiving groove 3, and a raised top cover flange 21 is formed at one end of the top cover 2 facing the side panel 1, the top cover flange 21 is located at the connection between the top cover 2 and the side panel 1, and the top cover flange 21 extends upward from the connection between the top cover 2 and the side panel 1.

[0043] In this embodiment, if Figures 2 to 6 As shown, the detection body 100 is formed with a positioning portion 110 extending toward the accommodating groove 3, and the bottom of the positioning portion 110 can abut against the bottom of the accommodating groove 3, thereby determining the position of the detection body 100 in the accommodating groove 3, thereby limiting the displacement of the detection body 100 in the vertical direction, and forming a reliable measurement reference for subsequent measurements. The bottom of the positioning portion 110 is preferably a planar structure that conforms to the accommodating groove 3, thereby increasing the contact area between the positioning portion 110 and the accommodating groove 3 and ensuring reliable positioning.

[0044] Specifically, Figure 2 and Figure 3As shown, at the connection between the side wall 1 and the top cover 2, the top cover 2 is located above the side wall 1, so that the bottom of the accommodating groove 3 is not in the same horizontal plane. In this embodiment, the bottom of the positioning portion 110 is formed with a first abutting portion 113 and a second abutting portion 114, and the first abutting portion 113 and the second abutting portion 114 have different heights in the vertical direction, wherein the first abutting portion 113 abuts against the bottom wall of the accommodating groove 3 surrounded by the side wall 1, and the second abutting portion 114 abuts against the bottom wall of the accommodating groove 3 surrounded by the top cover 2, thereby improving the positioning reliability of the detection body 100 in the vertical direction.

[0045] More specifically, in this embodiment, the groove walls of the receiving groove 3 are arranged to be inclined relative to each other, so that the receiving groove 3 is formed into a flared structure, and the positioning portion 110 is also correspondingly formed into a trapezoidal structure.

[0046] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, the positioning portion 110 is formed with a recessed snap-fit ​​groove 140 for the top cover flange 21 to extend into, so that the positioning portion 110 and the top cover flange 21 form a snap-fit ​​connection, thereby limiting the displacement of the detection body 100 in the width direction of the vehicle body, and further ensuring the reference fixation of subsequent measurements.

[0047] In this embodiment, the clamping groove 140 penetrates the detection body 100 to form a notch structure on the positioning portion 110, so that the clamping groove 140 has only a pair of opposite side walls, thereby ensuring that the top cover flange 21 is effectively inserted. In addition, the clamping groove 140 can be arranged between the first abutting portion 113 and the second abutting portion 114, and the clamping groove 140 and the first abutting portion 113 and the second abutting portion 114 are respectively connected by arc transition, so that the top cover flange 21 can be inserted into the clamping groove 140.

[0048] In a preferred embodiment, Figure 3 As shown, the two side walls of the clamping groove 140 facing each other are respectively in contact with the top cover flange 21 , so that the clamping groove 140 clamps the top cover flange 21 , thereby improving the positioning reliability of the detection body 100 in the width direction of the vehicle body.

[0049] Furthermore, in a preferred embodiment, Figure 3 As shown, the depth of the snap-in groove 140 is not less than the height of the top cover flange 21, so as to ensure that the top cover flange 21 can fully extend into the snap-in groove 140, thereby ensuring the reliability of the abutment between the first abutting portion 113 and the bottom wall of the receiving groove 3 surrounded by the side wall 1 and the abutment between the second abutting portion 114 and the bottom wall of the receiving groove 3 surrounded by the top cover 2, thereby avoiding the situation where the first abutting portion 113 or the second abutting portion 114 cannot contact the bottom wall of the receiving groove 3 and cause detection failure.

[0050] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the side of the positioning portion 110 facing the side panel 1 is formed as a first measuring portion 111, and the first measuring portion 111 is parallel to the side wall of the receiving groove 3 formed by the side panel 1, so that the distance between each part of the first measuring portion 111 and the side wall of the receiving groove 3 formed by the side panel 1 is equal, and the distance between the first measuring portion 111 and the side panel 1 is a first measuring spacing L3. The parameters of the first measuring spacing L3 are measured by a measuring tool. When the first measuring spacing L3 is within the range of the detection standard, the distance between the side panel 1 and the top cover 2 meets the assembly requirements, wherein the detection standard is the sum of the preset size and the offset, and the offset is ±1.5mm. The measuring tool can be a ruler-like component. When the first measuring spacing L3 is greater than the detection standard, it means that the welding spacing between the side panel 1 and the top cover 2 is large, and when the first measuring spacing L3 is less than the detection standard, it means that the welding spacing between the side panel 1 and the top cover 2 is small. According to the situation of large or small welding spacing, the welding fixture can be adjusted accordingly, so as to quickly achieve the qualified body-in-white.

[0051] It should be noted that the above-mentioned preset size can be the size actually measured from a standard white car body by the detection body 100, and of course it can also be the size set by the designer for this part of the structure.

[0052] Specifically, in this embodiment, Figure 4 and Figure 6 As shown, the receiving groove 3 is formed into a strip structure extending along the length direction of the vehicle body, and the detection body 100 is formed into a sheet structure perpendicular to the length direction of the receiving groove 3. This can meet the detection requirements while reducing the volume of the detection body 100, thereby achieving the convenience of storage, carrying, and use of the inspection tool for automobile production, which is easy and labor-saving.

[0053] It should be noted that during the detection, the detection body 100 is vertically placed in the receiving groove 3. In a preferred embodiment, a plurality of different positions are measured along the length direction of the receiving groove 3 to improve the measurement accuracy.

[0054] It should be further explained that the detection body 100 can be provided in multiple numbers, such as Figure 6 As shown, side panels 1 are provided on both sides of the body in the width direction, so that two receiving grooves 3 are formed, and a plurality of detection bodies 100 detect the two receiving grooves 3 simultaneously, so as to further improve the detection efficiency, thereby improving the production efficiency.

[0055] In a preferred embodiment, the detection body 100 is a stainless steel part, that is, the detection body 100 is made of stainless steel material, so that the detection body 100 has good anti-corrosion performance and avoids rust, thereby extending the service life of the detection body 100.

[0056] Furthermore, in this embodiment, if Figure 3 As shown, the side of the positioning portion 110 facing the top cover 2 is formed as a second measuring portion 112, and the second measuring portion 112 is parallel to the side wall of the receiving groove 3 surrounded by the top cover 2, so that the distance between each part of the second measuring portion 112 and the side wall of the receiving groove 3 surrounded by the top cover 2 is the same; the distance between the second measuring portion 112 and the top cover 2 is a second measuring spacing L4, and the second measuring spacing L4 is within the range of the detection standard, so that it can meet the needs when the requirements for the required welding quality are improved. The detection standard of the second measuring spacing L4 is also the sum of the preset size and the offset, and the offset is also ±1.5mm; under normal conditions, the second measuring spacing L4 has a relatively small effect on the warping of the top cover trim 4, but the shape accuracy of the top cover 2 may be reduced due to the influence of the welding process. Therefore, when the first measuring spacing L3 and the second measuring spacing L4 are both within their respective measurement standard ranges, the reliability of avoiding the warping of the top cover trim 4 can be improved.

[0057] Furthermore, in this embodiment, if Figure 3 As shown, the side wall at the top of the detection body 100 is formed with a protruding first detection portion 120 and a second detection portion 130, and the first detection portion 120 and the second detection portion 130 are respectively arranged on both sides of the accommodating groove 3, that is, the protruding directions of the first detection portion 120 and the second detection portion 130 are opposite.

[0058] Specifically, the first detection part 120 is arranged above the side enclosure 1, and the bottom of the first detection part 120 is formed as the third measuring part 121, the bottom of the third measuring part 121 is arranged horizontally, and the distance between the third measuring part 121 and the top of the side enclosure 1 is the third measuring spacing L5. The third measuring spacing L5 is within the range of the detection standard, indicating that the size between the bottom of the accommodating groove 3 and the top of the side enclosure 1 meets the design requirements, and the detection standard of the third measuring spacing L5 is also the sum of the preset size and the offset, and the offset is also ±1.5mm; the second detection part 130 is arranged above the top cover 2, and the bottom of the first detection part 120 is formed as the fourth measuring part 131, the fourth measuring part 131 is arranged horizontally, and the distance between the fourth measuring part 131 and the top of the top cover 2 is the fourth measuring spacing L6. The fourth measuring spacing L6 is within the range of the detection standard, indicating that the size between the bottom of the accommodating groove 3 and the top of the top cover 2 meets the design requirements, and the detection standard of the fourth measuring spacing L6 is also the sum of the preset size and the offset, and the offset is also ±1.5mm.

[0059] The first measuring distance L3 meets the detection standard to ensure that the roof cover trim 4 does not curl up after assembly. On the basis that the first measuring distance L3 meets the detection standard, when the third measuring distance L5 and the fourth measuring detection distance both meet the detection standard, it means that the position of the roof cover trim 4 in the accommodating groove 3 can be guaranteed to be accurate, thereby indicating that the welding of the side panel 1 and the roof cover 2 is qualified, laying a good foundation for subsequent automobile production.

[0060] According to the automobile production inspection tool of the utility model, after the side panel and the top cover are assembled, the positioning part is extended into the receiving groove, so that the bottom of the positioning part abuts against the receiving groove and the top cover flange is extended into the clamping groove, so that the position of the detection body in the receiving groove is fixed, which provides a guarantee for the accuracy of subsequent measurements; by comparing the first measurement distance with the detection standard, it is possible to judge whether the distance between the side panel and the top cover meets the assembly requirements. The operation is simple and easy to use, and the detection results can be obtained quickly, which greatly improves the detection efficiency of the white body and improves production efficiency; it effectively avoids the situation where the top cover trim strip flips over, ensures the accuracy of the position of the top cover trim strip, improves the assembly quality, and can detect all white bodies one by one, improves the detection reliability, and effectively prevents the occurrence of quality problems.

[0061] A detection device provided according to the utility model comprises a feeler gauge and the above-mentioned inspection tool for automobile production.

[0062] The feeler gauge is an existing measuring tool, and its specific structure and usage are not described here.

[0063] In this embodiment, the feeler gauge can be inserted between the first measuring portion and the side perimeter to measure the size of the first measuring interval. Compared with other measuring tools, the feeler gauge can obtain the size more conveniently, thereby further improving the detection efficiency.

[0064] Furthermore, in this embodiment, both the automobile production inspection tool and the feeler gauge are provided with mounting holes, and the detection device further includes a connector that is inserted through the mounting hole. Specifically, the mounting hole is provided on the detection body, and the connector can be a flexible connecting member such as a chain or a rope, so that the automobile production inspection tool and the feeler gauge are connected, so that the detection device forms an integrated structure for easy carrying. In a preferred embodiment, the automobile production inspection tool and the feeler gauge are detachably connected, so that detection bodies of different specifications can be replaced according to actual needs.

[0065] In addition, a plurality of detection bodies of different specifications can be passed through the connecting piece, and corresponding marks, such as vehicle model marks, are set on different detection bodies, so that an appropriate detection body can be selected for measurement according to actual needs.

[0066] According to the detection device of the utility model, the feeler gauge can be extended between the first measuring part and the side wall, so that the first measurement distance can be obtained more quickly, thereby ensuring that the detection efficiency is further improved, and then the production efficiency is improved, and the flipping of the top cover trim is effectively avoided, the accuracy of the position of the top cover trim is ensured, and the assembly quality is improved.
