The protective device for the probe of the sensor can well solve the problem of inconvenient operation of a Picoturn rotating speed sensor when measuring the rotating speed of the turbocharger compressor impeller.
Description
Technical field
The utility model relates to field of measuring technique, particularly a kind of protective device of testing turbo-charger blower impeller rotating speed sensor special probe.
Background technology
More and more higher along with engine power performance, economy, the feature of environmental protection etc. are required, supercharging technology has all obtained positive promotion and application in diesel engine and gasoline engine field, and turbosupercharger becomes the critical component of engine with supercharger.In the processs of the test such as coupling, the engine plateau at supercharger and engine demarcated, the anti-negative pressure leakage of oil of research supercharger, all need to measure the rotating speed of turbosupercharger.Therefore, various high performance turbo charger speed sensors arise at the historic moment.
The Picoturn speed probe is a high-precision sensing apparatus of measuring the turbo-charger blower impeller rotating speed specially, mainly is made up of sensor, controller, display, lead.Its principle of work be when gear teeth of pressure booster blower impeller and sensor probe near the time, the inductance that they produce will be reduced by the eddy effect dilution, TPC (time-to-digit converter) then measures the variation inductance frequency, carry out data processing by DSP again, provide an output signal that is directly proportional with rotating speed at last.The long 60mm of sensor, diameter M5 * 0.8, the long 1.5m of lead.In the measuring process, bore hole and the tapping of a Φ 5 on the turbosupercharger spiral case, sensor probe is screwed in the threaded hole, the distance of the tripping mechanism of qi impeller gear teeth is about 1～2 mm.Be easy to make the probe clamping stagnation in the threaded hole of spiral case because engine luggine and pressure shell expand with heat and contract with cold during test, need certain rotation external force when therefore operating.In order to prevent iron core probe because the external force that rotation produces and impaired, probe screw in the process that screws out spiral case in, need two people to cooperate, people's rotating detector wherein, people's pilot makes it rotate with unequal angular velocity.Both made troubles like this, and be easy to damage because of mismate makes the probe unbalance stress to test.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of sensor probe protective device of testing the turbo-charger blower impeller rotating speed is provided.
The technical solution of the utility model is: a kind of sensor probe protective device of testing the turbo-charger blower impeller rotating speed, it is made up of thread bush, setting nut and double threaded screw.On thread bush, be provided with sensor conductor hole and threaded hole.On setting nut, be provided with sensor probe threaded adjusting hole.On the cylindrical at double threaded screw two ends, be respectively equipped with external thread, on double threaded screw, also be provided with setting nut hole and sensor probe hole.
Setting nut is installed in the setting nut hole on the double threaded screw, and thread bush is screwed in the big end of double threaded screw by being threaded.
During test; the double threaded screw of sensor probe protective device is fixed in the screw thread instrument connection of turbocharger air compressor spiral case; setting nut is screwed on the sensor probe by being threaded; the setting nut that will be connected with sensor probe again is installed in the setting nut hole on the double threaded screw, and then the thread bush of screwing on double threaded screw.
The sensor probe protective device of the test turbo-charger blower impeller rotating speed that the utility model provides is to go up the distance that relative position is controlled the sensor probe and the impeller gear teeth by the axle of regulating setting nut and sensor probe; regulating thread bush can locate setting nut; prevent moving axially of sensor probe, guarantee that the distance of the sensor probe and the impeller gear teeth is constant in process of the test.
The utility model compared with prior art has following characteristics:
The sensor probe protective device that the utility model provides can solve the unhandy problem of Picoturn speed probe well when test turbo-charger blower impeller rotating speed; rotatablely moving of sensor probe location is converted to rectilinear motion by setting nut during with test; not only can prevent to make the sensor probe clamping stagnation in the threaded hole of spiral case because of the damage of the rotation sensor probe that causes with because of engine luggine and spiral case expand with heat and contract with cold; can also operate separately by a people, convenient and practical.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
