Tooling for catalytic muffler test

Abstract

The invention relates to a catalytic muffler testing tool. A top face of a vibration platform is connected with a tool base plate via a connecting pin, a top face of the tool base plate is provided with an inner fixed boss, a catalytic muffler to be tested is arranged on a top face of the tool base plate, the inner fixed boss is plugged in the catalytic muffler to be tested, the tool base plate is provided with a via hole, a bottom end of the tool base plate is provided with an air inlet tube which is communicated with an inner cavity of the catalytic muffler to be tested via the via hole, the air inlet tube is communicated with a hot air blower, a top end of the catalytic muffler to be tested is provided with an upper pressing plate which is connected with the tool base plate via a long screw rod, and the middle part of the upper pressing plate is provided with an air outlet hole. The catalytic muffler testing tool can be used for testing catalytic mufflers of a plurality kinds of specifications, the tool does not need to be redesigned, the tool is enabled to have multiple functions, a testing cycle can be shortened, the quantity and the kinds of tools that need to be manufactured can be reduced, catalytic muffler testing efficiency can be improved, and testing cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of structural performance testing of automobile muffler equipment, in particular to a tooling for catalytic muffler testing. Background technique [0002] With the acceleration of my country's economic development and infrastructure construction, my country's automobile production has increased from 3.2512 million in 2002 to 18.4189 million in 2011, an increase of nearly 6 times. At the end of 2002, the number of civilian vehicles in my country just exceeded 20 million; at the end of 2011, the number of civilian vehicles reached 106 million. The increase in the production and ownership of automobiles has led to more and more serious pollution from exhaust gas. With the country's increasing emphasis on energy conservation and emission reduction, realizing energy conservation, low carbon, and environmental protection has become the core goal of my country's "Twelfth Five-Year Plan", which pushes the emission ...

Problems solved by technology

However, at present, when performing thermal vibration or thermal cycle tests on catalytic mufflers, each type of catalytic muffler requires a special test tool corresponding to it, which leads to a wide variety of tooling specifications, and each tooling is from the design It takes a certain period from trial production to actual application, and requires a certain amount of manpower, material and financial resources, which affects the test progress, increases the test cost, and relatively low test efficiency

Moreover, in the prior art, when thermal vibration testing is performed on the catalytic muffler, the catalytic muffler is usually installed vertically directly on the vibrating table, and the high temperature in the test will affect the service life of the vibrating table
