Riveting forming quality detection template of riveting structure of wagon and detection method thereof

Abstract

The invention discloses a riveting forming quality detection template of a riveting structure of a wagon. The riveting forming quality detection template of the riveting structure of the wagon comprises a detection template body, wherein two detection grooves A and B are formed in the detection template body, the detection groove A is used for detecting whether the maximum extending distance L2 of a short-tail riveting pin in the riveting structure relative to a sleeve ring and the length L3 and diameter D of the sleeve ring are qualified, and the detection groove B is used for detecting whether the minimum extending distance L1 of the short-tail riveting pin in the riveting structure relative to the sleeve ring is qualified. Detection of riveting forming quality of the riveting structure is integrated on one detection template through a stop-pass gauge, whether the riveting structure is qualified can be directly judged through detection with the method, and the operation method is simple and high in detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of railway freight car manufacture and maintenance, and in particular relates to a quality inspection template and a detection method for a riveted riveting structure of a railway freight car.

Yunzhuang Wagon [2010] No. 575 issued the "Review Opinions on the Anti-detachment Scheme of Railway Wagon Suspension Parts" and "Railway Wagon System The forming dimensions of the riveting pins are L1, L2, L3 in the "Technical Conditions for the Special Riveting Pins for Railway Freight Cars" and "Technical Conditions for the Special Riveting Pins for Railway Freight Cars" in the "Special Riveting Pins for Railway Freight Cars" and "Technical Conditions for Riveting Pins for Railway Freight Cars". , D should comply with the relevant regulations, ...

AI Technical Summary

Problems solved by technology

[0003] The ring forming quality after the short-tail riveting pin is riveted with the ring directly affects the life of the riveted structure and affects the driving safety of railway wagons. The reliability of the ring forming quality detection method is particularly critical. Vernier calipers and steel rulers are generally used to detect sleeves. The diameter and length of the ring after riveting is time-consuming and labor-intensive
