Abstract
The invention relates to a test device for the air tightness of a steering frame air spring. The test device is provided with a pressing plate; the pressing plate is provided with a positioning pin hole which is matched with a positioning pin of the steering frame air spring; a pair of stand columns is fixed on the upper surface of the pressing plate; a fixed pressing head base spans and is fixed above the stand columns; the pressing head base is provided with a groove for accommodating a pressing head of a static load test stand; a seal cover corresponding to an air outlet of the air spring is arranged on the lower surface of the pressing plate; an inner ring of the seal cover is matched with a round table surface of the air outlet of the air spring to be sealed. In the test device, the air tightness in the test process is ensured by test expansion pressure and a rubber seal structure according to the characteristic of an interface of the air spring, and the static load test stand is designed to ensure that the test device is easy to operate, safe and reliable when loads are applied to the air spring.
Description
Technical field
The present invention relates to a kind of bogie air spring tightness test device, belong to rail truck and make the safety technique field.
Background technology
Because the inlet structure design is comparatively special on the PW200K bogie air spring, compares with common air spring air intake opening, it does not have helicitic texture for taper, and when carrying out air-tight test, existing frock, equipment can't guarantee sealing property.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of safe and reliable, simple to operate, uses flexibly the bogie air spring tightness test device that impermeability is good.
In order to solve above technical matters; Bogie air spring tightness test device provided by the invention; It is characterized in that: have pressing plate; Said pressing plate offers the dowel hole that cooperates with bogie air spring register pin; The upper surface of pressing plate is fixed with a column; Said column top across fixedly pressing head seat; Said pressing head seat has the groove that holds the static test bed pressure head; Said pressing plate lower surface is provided with the gland bonnet corresponding with the air spring gas outlet, and the inner ring of said gland bonnet cooperates with the round table surface of air spring gas outlet realizes sealing.
Further, the below of said pressing plate is provided with compound seat board, and said compound seat board central authorities offer and hold the through hole that gland bonnet inserts.
Further, said pressing plate upper surface also is provided with suspension ring.
The present invention is according to the air spring interface characteristic, through self the test swelling pressure and rubber sealing structure, and the impermeability in the warranty test process, and be designed with the interface with static test bed, simple to operate, safe and reliable when guaranteeing to the air spring imposed load.
Beneficial effect of the present invention is following: (1) the present invention can make the PW200K air spring normally carry out air-tight test, guarantees impermeability; (2) simple in structure, cost is low; (3) simple to operate, safe and reliablely, factory enhances productivity for realizing safety in production, made contribution.
