Technical field
The utility model belongs to the equipment that is used for the detected pressures table, relates generally to a kind of tensimeter on-line measuring device.
Technical field
Tensimeter is an important spare part on the rolling bearing fatigue life experimental machine.Be used for showing experiment load pressure and lubricating system pressure.And experiment load is an important parameter of rolling bearing fatigue life test, and the applying, adjust, control of experiment load all needs the tensimeter on the machine by experiment to show.Lubricating system pressure is in order to guarantee bearing lubrication, heat radiation essential condition.
The tensimeter that uses on the Type B rolling bearing fatigue life experimental machine has three, is used for wherein showing that the tensimeter of test load has two (each one on radial and axial tensimeters), also has a pressure that is used for showing lubricating system.Testing crew all must be tested to tensimeter before each test, to determine whether its precision and sensitivity reach requirement, in order to guarantee manometric display precision, require to use need after a period of time tensimeter disassembled after, send that standard metering department identifies, verification or maintenance, the inspection department verification needs the regular hour.Testing machine is Once you begin worked, need turn round uninterruptedly 24 hours every days, individual hour of the few person's hundreds of of a general process of the test, many persons tens thousand of hours, tensimeter on the testing machine is in pressure state all the time, carries out verification outside can't in the cycle of regulation tensimeter being sent.
If in use often change tensimeter, can bring following problem:
1, be subjected to the restriction of experimental machine structure, it is more loaded down with trivial details and need certain hour to change tensimeter.The bearing fatigue experiment generally is not allow request stop, and the lighter can influence the test progress like this, and weight person influences experimental precision and result.
2, metering verification workload is big.About surplus my the unit present tensimeter of various fatigue lifetime of experimental machine has 200 piece, all come into operation, need the workload and the expense of metering verification to well imagine.
3, frequently change tensimeter and damage tensimeter and relevant connecting piece easily, and cause system's leakage of oil pressure to descend, influence the test accuracy of product.
Summary of the invention
The purpose of this utility model provides a kind of tensimeter on-line quick detection device, and it can detect fast to the tensimeter of working on the testing machine is online.
The purpose of this utility model can adopt following technical scheme to realize: it comprises a fluid pressure type hand operated press, retaining valve and master gauge, the oil cylinder of retaining valve one end and fluid pressure type hand operated press is connected, the other end connects master gauge by oil duct, and the oil circuit that connects retaining valve and master gauge is provided with the interface that is connected with tested tensimeter.
The interface that described and tested tensimeter is connected is a three-way interface
As from the foregoing.The utility model be precision (0.4 grade) tensimeter that adopts a process regularly to measure to identify as standard scale, then other online or standby tensimeter is measured, by comparing with master gauge, realization is to the detection of tested tensimeter precision.
Innovative point of the present utility model is to have solved testing machine tensimeter on-line quick detection, has guaranteed the manometric precision of use and the normal control of experimental machine hydraulic system; It can solve online detection simultaneously and acknowledgment copy detects problem.Avoid the tensimeter censorship to influence the carrying out of experimental work, saved measuring cost and censored time, improved work efficiency, alleviated operator's labour intensity, reduced the goods and materials loss.The use of tensimeter on-line measuring device can be saved measuring cost, has improved work efficiency, has alleviated operator's labour intensity, has reduced the goods and materials loss.And the utility model structure is very simple, and required workpiece and connecting piece are standard component, makes easily, and is easy to operate, measure accurately, is fit to very much the production scene and uses.
