The size deviation of the sealing strip may cause the door to be not tightly sealed, water leakage, air leakage, and even affect the driving safety and comfort. Therefore, accurate size detection of the automobile front door hole sealing strip is an indispensable link in the automobile manufacturing process.

[0003] The existing automobile front door hole sealing strip detection technology mainly relies on comprehensive detection tools, such as the “front and rear door hole sealing strip assembly detection tool” with the announcement number CN220541894U, which discloses a reference plate, the reference plate is provided with a main body simulation block, the main body simulation block is provided with a front door hole and a rear door hole, the main body simulation block is detachably connected with a front door sheet metal simulation block, a rear door sheet metal simulation block, a B column cover plate simulation block, a rear door corner window simulation block and a plurality of door hole sealing strip installation simulation blocks, the front door hole is connected with the front door sheet metal simulation block or the automobile front door assembly, and the rear door hole is connected with the rear door sheet metal simulation block or the automobile rear door assembly. The main body simulation block is provided to construct the door hole structure of the automobile, and the detection of the parts at the front and rear doors can be performed.

[0004] Although the existing detection tool can simulate the overall structure of the automobile door hole, its design is too comprehensive and lacks special optimization for sealing strip size detection. Although this design is suitable for the assembly detection of various parts, it has limited precision detection capability for the size of the sealing strip and cannot meet the demand for high-precision detection. In addition, the structure of the existing detection tool is complex, the cost is high, and the detection process is cumbersome. CONTENT OF THE UTILITY MODEL

[0005] The technical problem to be solved by the present application is to provide a size detection tool for an automobile front door hole sealing strip, which has the characteristics of simple structure, convenient operation and accurate size data, so as to meet the strict requirements of modern automobile manufacturing for sealing strip quality control.

[0006] The technical scheme adopted by the present application is: the automobile front door hole sealing strip size detection tool, comprising a base plate, a mounting seat, a pressing and fixing assembly, a plurality of grating rulers and a plurality of scale detection blocks are arranged on the base plate, the door hole sealing strip to be detected is installed at the mounting seat, the grating ruler is arranged along the direction of the mounting seat, the pressing and fixing assembly is located on one side of the mounting seat and is used for pressing and fixing the door hole sealing strip to be detected at the mounting seat, the scale detection block is located on the other side of the mounting seat, a calibration scale is arranged on the surface of the scale detection block, and the scale detection block acts on the surface of the door hole sealing strip to be detected for calibration.

[0007] Compared with the prior art, the present application has the advantages that the present application only includes basic components such as a base plate, a mounting seat, a pressing and fixing assembly, a grating ruler and a scale detection block, and the structure is greatly simplified compared with the complex structure of the existing comprehensive detection tool. This simplified design reduces the number of parts and assembly complexity, reduces manufacturing costs and maintenance difficulty. And each component (such as the mounting seat, the pressing and fixing assembly, the grating ruler and the scale detection block) is independently arranged and has a clear function, which facilitates disassembly, replacement and maintenance, improves the versatility and flexibility of the detection tool.

[0008] The grating ruler is a high-precision displacement measurement device that can accurately measure the size change of the sealing strip along the direction of the mounting seat. Its measurement accuracy is much higher than that of traditional mechanical measurement tools, and it can provide millimeter or even micrometer level size data to meet the high-precision requirements of modern automobile manufacturing for sealing strip size. The scale detection block is not only used for calibration, but also serves as a reference standard to further improve the accuracy of detection. Through the combination of accurate measurement of the grating ruler and auxiliary calibration of the scale detection block, measurement errors can be effectively reduced to ensure the reliability of the detection results.

[0009] The mounting seat and the scale detection block can be adjusted according to different specifications of the sealing strip, so that the detection tool can adapt to the detection of various models of automobile front door hole sealing strips. This universal design reduces the demand of enterprises for different detection tools and reduces equipment procurement costs.

[0010] In some embodiments of the present application, the mounting seat comprises an inner stop bar and an outer stop bar arranged on the base plate, and there is a spacing between the inner stop bar and the outer stop bar, and the door hole sealing strip to be detected is installed between the inner stop bar and the outer stop bar.

[0011] By arranging the inner stop bar and the outer stop bar, the inner side and the outer side edges of the door hole sealing strip can be accurately limited.

At the same time, the structure of the inner stop bar and the outer stop bar is simple, easy to process and adjust, and can adapt to sealing strips of different sizes, further enhancing the versatility and flexibility of the detection tool.

[0012] In some embodiments of the present application, the mounting seat comprises a plurality of mounting blocks arranged regularly to form the mounting seat.

[0013] The design of regularly arranging a plurality of mounting blocks to form the mounting seat makes the mounting seat flexible to adjust according to sealing strips of different shapes and sizes.

In addition, the regularly arranged mounting blocks can provide stable support to ensure that the sealing strip remains flat during the detection process, thereby improving the accuracy and reliability of the detection.

[0014] In some embodiments of the present application, the mounting seat comprises a first segment, a second segment and a third segment connected in sequence, the first segment, the third segment and the second segment are curvedly transitioned, the included angle between the first segment and the second segment is an acute angle, and the included angle between the third segment and the second segment is an obtuse angle; the first grating ruler and the second grating ruler are arranged on the base plate, the first grating ruler is arranged parallel to the first segment, and the two ends of the first grating ruler are extended to the outside of the first segment, and the second grating ruler is arranged parallel to the second segment, and the two ends of the second grating ruler are extended to the outside of the second segment.

[0015] This segmented and angularly changed mounting seat design can better adapt to the complex shape of the door hole sealing strip, especially for sealing strips with curves or angles. By accurately setting the included angles between the first segment, the second segment and the third segment, the fit of the sealing strip on the mounting seat can be higher, and the measurement error caused by shape mismatch can be reduced. In addition, this design can also improve the flexibility of detection, enabling it to cover more types of sealing strips, further enhancing the universality and adaptability of the gauge.

[0016] In some embodiments of the present application, the grating ruler comprises a fixed seat, a scale grating and a reading head, the fixed seat is arranged on the base plate, the two ends of the scale grating are mounted on the fixed seat, and the grating ruler is higher than the mounting seat, the reading head is slidably arranged on the scale grating, and the reading head is inclinedly arranged towards the first segment or the second segment.

[0017] This design of grating ruler can provide high-precision size measurement, and the inclinedly arranged reading head can better read the length of the sealing strip, reduce measurement error and improve detection accuracy. At the same time, the stable structure of the fixed seat and the scale grating ensures the repeatability and reliability of the measurement. This design not only improves the accuracy of detection, but also enhances the adaptability of the gauge to complex shape sealing strips, meeting the requirements of high-precision detection.

[0021] The design of the adjusting bolt set allows the relative position of the pressing rod and the mounting strip to be flexibly adjusted according to the thickness and shape of the sealing strip.
