Description
Technical Field
The utility model relates to a railway product spare part manufacturing field especially relates to a detect rivet height and examine utensil for dovetail type powder metallurgy brake lining in batches.
Background
In recent years, the high-speed railway in China has great and profound development, and the mileage of the high-speed railway is close to 2 kilometers and covers over 50 million population cities by 2020, at that time, the four longitudinal and four transverse railway rapid passenger transport system in China is to be built comprehensively, and China enters the high-speed rail era.
As the speed of trains increases, how to safely stop trains running at high speed is an important issue related to life and property safety. The train brake has various modes such as resistance brake, magnetic track brake, eddy current brake, friction brake and the like, wherein the friction brake is indispensable. The friction braking mode is to convert kinetic energy into heat energy through friction and then dissipate the heat energy into the atmosphere. The friction brake of the high-speed train usually adopts a disc brake mode, and the purpose of consuming the kinetic energy of the train is achieved by utilizing the mutual friction between a brake disc and a brake pad. Therefore, the performance of these two components becomes an important aspect in relation to the operational safety of the train.
At present, high-speed motor train units operated on China railways mainly comprise CRH1, CRH2, CRH3 and CRH5 series, and all use a disc brake mode. The brake pad and brake mounting interface is divided into a dovetail type (including universal and non-universal) and a non-dovetail type. And whatever interface type, the brake pad is assembled by a friction body component and a steel back.
The connection form of the friction body assembly and the steel back in the dovetail type powder metallurgy brake pad can be divided into two types: the friction body assembly is connected with the steel back in a rivet riveting mode. At present, the dovetail type powder metallurgy brake pad is mostly riveted by using a rivet. Therefore, the sizes of all parts of the rivet are required to be checked, if any size of the rivet deviates, the riveting of the steel backing and the friction body assembly is not firm, the brake pad needs to be riveted again, and the working time and the working efficiency are increased. The difference between the powder metallurgy brake lining rivet and the daily life rivet lies in that a cylindrical boss which is larger than the diameter of the rivet rod is arranged between the rivet cap and the rivet rod, and the design increases the difficulty of inspection work.
At present, a special gauge special for detecting the whole size of the rivet for the powder metallurgy brake pad does not exist. Therefore, a rivet full-size detection tool special for detecting the dovetail type powder metallurgy brake pad is urgently needed to be designed.
