Description

TECHNICAL FIELD

[0001] The utility model relates to railway vehicle assembly detection technical field, concretely relates to a comprehensive detection device for side frame. BACKGROUND

[0002] In the braking system of railway vehicles, bolsters and side frames play an important role in force and torque transmission as key components. They are not only responsible for positioning, supporting and connecting other components, but also directly affect the performance and reliability of the entire braking system. Therefore, the size and shape detection of bolsters and side frames is particularly important.

[0003] However, the existing technology has significant shortcomings in the size and shape detection of bolsters and side frames. Traditionally, simple measuring tools such as calipers and single templates are used for detection, which cannot provide comprehensive and systematic evaluation standards, making it difficult to ensure that the assembly size and shape tolerance fully meet the design requirements. The accuracy of these parameters is directly related to the correct positioning and effective connection of the braking components, and any deviation may lead to assembly failure or performance degradation. In addition, considering the large number of applications of bolsters and side frames in railway vehicles, the use of traditional single tool detection method is extremely inefficient, which not only increases the production cycle, but also increases the manufacturing cost, and it is difficult to meet the quality control needs of mass production. SUMMARY

[0004] The utility model intends to provide a comprehensive detection device for side frame, which can complete the detection of multiple matching sizes and shape tolerances of the side frame in one station, and improve the detection efficiency at a low cost without affecting the detection accuracy requirements.

[0005] The basic scheme provided by the utility model is: a comprehensive detection device for side frame, including a framework, two main supports, four support one, two support two, two prisms and two welding supports; the framework is in a cuboid structure, including four side plates, and four installation spaces of support one are symmetrically arranged at the upper four corners, and one support one is installed in each installation space; the two support two are installed outside the two side plates in the length direction of the framework, and the two support two are symmetric about the middle line in the length direction of the framework; the two main supports are installed outside the same side plate in the length direction of the framework, and the two main supports are located on both sides of the support two of the side plate; the two welding supports are symmetrically installed at the two ends of the top surface of the framework along the length direction, and the two support one at the corresponding end are located below the two welding supports on both sides of the end; the two prisms are respectively installed on the top surface of the two welding supports;

[0006] The top surface of the support one, support two and prism is respectively installed with a boss one, a boss two and a boss three, wherein the top surface of the boss one and the boss two is flush with the top surface of the framework, and the top surface of the boss three is parallel to the top surface of the framework.

[0007] The utility model discloses a working principle and the advantage lies in: the combination of the framework, two main supports, four support no. 1, two support no. 2, two prisms and two welding supports forms an efficient and accurate side frame detection device. The main support cooperates with support no. 1 and support no. 2, and a stable placing space is formed, which ensures that the detected part can be stably placed on the detection device, and the plane design of the top of each support provides a solid foundation for supporting the detected part, and helps to ensure the position accuracy of the part during detection. The top surface and both side pillar surfaces of the prism not only fix the detected part, but also play an auxiliary leveling role, ensuring that the part surface is in an ideal state for subsequent detection. Through the cooperative work of these components, the detected part can be quickly positioned and fixed, and the sample plate is used to assist in detecting the length, width, height, assembly size and parallelism, perpendicularity and other dimensions and geometric tolerances that are not convenient to directly measure.

[0008] Compared with the prior art, the comprehensive detection device forms a space and a positioning point, so that the detected part can be quickly and accurately placed in position, and the ideal fixing and leveling state can be achieved through simple adjustment. Using the sample plate for auxiliary detection, not only can the basic dimensions such as length, width and height be effectively and accurately measured, but also the geometric tolerances such as assembly size, parallelism and perpendicularity that are difficult to directly quantify can be evaluated, so that whether the side frame meets the drawing requirements can be comprehensively checked, and the human error can be effectively reduced due to the use of the sample plate during the process. This detection method is particularly suitable for solving the problem of spatial dimension detection of large parts, greatly improving the detection accuracy and speed. In addition, due to the modular design concept, the entire system is easy to adjust and optimize according to different detection requirements, further enhancing the application flexibility and practicality. This not only saves a lot of manpower and material resources, but also provides strong technical support for quality control in industrial production. In addition, while ensuring effective detection, the special design of the shapes and position arrangement of the components effectively reduces the cost and space occupied by the device, so that the device is further optimized and embodies the beneficial effects of economy and applicability.
