Description
Technical field
The present invention relates to a kind of bearing pin run-in index size sensor transformational structure, be mainly used in workpiece performance test, disconnection during size sensor conversion, connection, belong to field of electromechanical technology.
Background technology
At present, locking type hydraulic damper is a kind of industrial pipeline bracing or strutting arrangement, is all widely used in electrician, steel mill, chemical plant.This damper under arms before to carry out the test that two relate to load and speed parameter, one be under low speed frictional resistance test, two be under rated load locking velocity test.Fig. 1 is the schematic diagram of damper test macro, and general oil cylinder, front stall maintain static, and tailstock is bolted to above basic with a lot of or adopts pressure mechanism to be fixed on basis, and sensor is also screwed on tailstock to tens bolts with several.Frictional resistance generally only allows between 1% ~ 2% rated load.Because two kinds of load magnitude differences are larger, in two tests, in order to ensure identical measuring accuracy, the load transducer of different range must be adopted, namely in low speed friction resistance test, adopt the sensor of small-range, in the locking velocity test under rated load, adopt the sensor of wide range.More the workload of emat sensor is relatively large.
Current way installs a sensors of large measurement range on testing table tailstock, then on sensors of large measurement range, a small-range sensor is connected in series, first do low speed friction resistance test, small-range sensor is pulled down after finishing, again damper is connected to sensors of large measurement range, does the locking velocity test under rated load.Also the method that the testing table had adopts is, elder generation is arranged on sensors of large measurement range on testing table A tailstock, small-range sensor is arranged on testing table B tailstock, when doing low speed friction resistance test, damper is connected on the small-range sensor be fixed on B tailstock, when doing the locking velocity test under rated load, small-range sensor and B tailstock are pulled down, is replaced with sensors of large measurement range and A tailstock.No matter which kind of method, all needs first damper one end to be taken apart, then disassembling sensor or replacing tailstock.Because dismounting damper, disassembling sensor and replacing tailstock are all pretty troublesome things, therefore cause that test job labour intensity is large, inefficiency.In some cases, such as nuclear power plant's prophylactic repair, a large amount of dampers pulled down need test, and more emat sensor often will account for the test duration of more than 1/3rd, affects repair schedule very much.
Summary of the invention
