Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of body detection tooling, in particular to a railway passenger car elastic body detection tooling. BACKGROUND

[0002] The side bearing is located between the vehicle body and the running gear, and it mainly has two kinds of gap side bearing and elastic side bearing, among which the elastic side bearing is more common. The elastic side bearing is usually composed of a side bearing seat, an elastic body and a wear plate, etc. It can realize the elastic connection between the vehicle body and the bogie through its own elastic deformation such as shear and compression deformation, etc., and can effectively inhibit the snake motion of the bogie and improve the stability and stability of the vehicle operation.

[0003] The side bearing device is a key component connecting the vehicle body and the bogie, and its assembly precision not only affects its stable operation, but also plays a decisive role in the overall performance of the railway passenger car. Therefore, before installation, the outer contour size of the side bearing seat and the outer contour size of the side bearing box on the frame body need to be measured. Precise size matching can avoid abnormal wear or uneven stress of the side bearing device during operation, reduce the hidden danger of driving safety. At present, the size detection of the elastic side bearing body of the domestic railway passenger car is still mainly in the manual detection mode. The detection process needs to rely on the cooperation of traditional measuring tools such as vernier caliper, depth gauge and plug gauge. However, in the manual detection mode, due to the large weight of the side bearing body, the detection personnel need to repeatedly adjust the placement position of the side bearing body to find the best measurement angle and measurement point, which significantly increases the labor intensity of the detection personnel. Moreover, the operation process of repeatedly adjusting the position and recording the readings for multiple times is time-consuming. Especially when multiple vehicles need to be processed at the same time during the peak maintenance period, the low efficiency of manual detection is more prominent. Not only does it affect the overall production or maintenance progress, but it also increases the risk of reading error due to operator fatigue, which may potentially affect the detection accuracy. Therefore, the present application provides a railway passenger car elastic body detection tooling to meet the needs. SUMMARY

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a first outer contour measuring mechanism and a second outer contour measuring mechanism, the first contour measuring mechanism can quickly measure the length and width of the outer contour of the side bearing box, as well as the arc length and curvature at the corners of the outer contour. The second outer contour measuring mechanism can quickly measure the length and width of the outer contour of the side bearing body, as well as the arc length and curvature at its corners. It also assists in aligning the side bearing box and the side bearing body, facilitating the rapid installation of the side bearing body into the side bearing box after measurement. This device measures a single model of side bearing box and side bearing body. Through rapid measurement, it saves manual labor time, improves work efficiency, and ensures accurate measurement, guaranteeing the quality of the side bearing box and side bearing body, thereby ensuring safety during railway passenger car operation. It also ensures that the side bearing body can be accurately and stably installed in the side bearing box, further guaranteeing the safety of railway passenger car operation.

[0018] By incorporating a first measuring frame and a second measuring frame within the first outer contour measuring mechanism, the length of the side bearing box can be measured using the distance between the first measuring frames. The arc length and curvature of the side bearing box corners can be measured using the arc length and curvature of the second measuring frame to ensure they meet the standards. Furthermore, the width of the side bearing box can be measured using the distance between the extended sides of the two second measuring frames to ensure it meets the standards. This allows for the rapid measurement of the outer contour dimensions of the side bearing box, ensuring that it can be quickly and stably installed and used, and thus guaranteeing that the outer contour dimensions of the railway passenger car side bearing box meet the standards.

[0019] By incorporating a connecting block, a third measuring frame, and a guide block within the second outer contour measuring mechanism, the length of the side bearing body can be measured to ensure it conforms to the standard using the distance between the two connecting blocks. The curvature and arc length of the four corners of the side bearing body can be measured using the curvature and arc length of the third measuring frame. Furthermore, the distance between two adjacent guide blocks is equal to the width of the side bearing body, allowing for the measurement of the width of the side bearing body to ensure it conforms to the standard. This rapid measurement of the outer contour dimensions of the side bearing body ensures its quick and stable installation and use, thereby guaranteeing that the outer contour dimensions of the railway passenger car side bearing body strictly conform to the standard.

[0020] By setting the first measuring block and the second measuring block in the second outer contour measuring mechanism, whether the two slot widths on the side bearing body meet the standard can be measured by the first measuring block and the second measuring block, further ensuring the quality of the side bearing body, so as to ensure the shape adaptation of the side bearing body and the side bearing box. The slotting on the side bearing body is a special structure designed according to its functional positioning, and the function of different slotting is directly related to the assembly logic, load transmission and component adaptation of the side bearing. The re-measurement of the slot width before installation ensures the effective implementation of the slotting function and avoids assembly risks.

[0021] By setting the first guide part in the second outer contour measuring mechanism, the side bearing body can be positioned more quickly and accurately by the guidance of the first guide part, and the center position of the side bearing body is aligned with the center position of the side bearing box by the limiting of the connecting block and the third measuring frame, which facilitates the outer contour size measurement of the side bearing body and facilitates the subsequent installation of the side bearing body in the side bearing box.

[0022] In summary, the device can not only accurately and efficiently measure the outer contour of the side bearing box and the side bearing body, but also assist in positioning the side bearing body to improve the convenience of measurement and installation. The cooperation between the structures in the device ensures the adaptability of the railway passenger car parts, so as to achieve stable installation and finally ensure that the adaptation between the railway passenger car parts meets the standard.
