Description
Technical field
The present invention relates to a kind of bearing pin staggered form size sensor transformational structure, it is mainly used in workpiece performance test, greatly
Disconnection during little sensor conversion, connection, belong to field of electromechanical technology.
Background technology
At present, locking type hydraulic damper is a kind of industrial pipeline support meanss, has extensively in electrician, steel mill, chemical plant
General application.This antivibrator under arms before to carry out two and be related to load and the test of speed parameter, one is rubbing under low speed
Wipe resistance test, two is the locking velocity test under rated load.Fig. 1 is the schematic diagram of antivibrator test system, general oil cylinder,
Front stall maintains static, tailstock with much individual be bolted on the basis of or on the basis of being fixed on using pressure mechanism, sensor
It is screwed on tailstock with several to more than ten bolt.Frictional resistance typically only allows between 1%～2% rated load.Due to
Two kinds of load magnitude differences are larger, in two tests, in order to ensure identical measuring accuracy it is necessary to adopt the load of different ranges
Lotus sensor, adopts the sensor of small-range in low speed friction resistance test, in the locking velocity test under rated load
Sensor using wide range.The workload of more emat sensor is relatively large.Current way is to install on testing stand tailstock
One sensors of large measurement range, then concatenates a small-range sensor on sensors of large measurement range, first does the examination of low speed friction resistance
Test, pull down small-range sensor after finishing, then antivibrator is connected to sensors of large measurement range, do the locking velocity under rated load
Test.Also the method that the testing stand having adopts is first sensors of large measurement range to be arranged on testing stand a tailstock, small-range senses
Device is arranged on testing stand b tailstock, does and during low speed friction resistance test, antivibrator is connected to the small-range being fixed on b tailstock
On sensor, when doing the locking velocity test under rated load, small-range sensor and b tailstock are pulled down, is replaced with wide range
Sensor and a tailstock.No matter which kind of method, is required for first antivibrator one end being taken apart, then disassembling sensor or replacing tailstock.By
It is all pretty troublesome thing in dismounting antivibrator, disassembling sensor and replacing tailstock, thus result in test job high labor intensive, work
Make efficiency low.In some cases, such as nuclear power plant's periodic inspection, a large amount of antivibrators pulled down need to test, and change sensing
Device often will account for for more than 1/3rd testing time, affects very much repair schedule.
