Existing market is generally used comparatively advanced is 1, have the mechanical presetting system dynamometry type torque spanner of adjusting function.2, there is the dynamometry type torque spanner of the digital displaying function that can freely arrange by Single-chip Controlling.But this two torque spanner still exists certain defect, the pre-debugging of machinery certainty of measurement is low.The dynamometry type torque spanner of digital displaying function, in use afterburning inertia can cause measure error greatly and the problem of safety operation equally, thereby can Measurement accuracy again can be accurately the manual measurement instrument in breakaway source automatically, particularly important under the fast-developing situation of science and technology.
With the 730D electronic type dropout torque spanner that has German Da Weili to release that this project comparatively approaches, it is the expansion link that metallic elastic material is made that its torsion is measured adjustment component element.In use, due to the wearing and tearing of mechanical part, must often carry out degree of accuracy correction.That its Jie structure Fu Za ﹑ arranges is loaded down with trivial details, certainty of measurement is low (2% precision), service life is short.Therefore be badly in need of at present a kind of can Measurement accuracy again can be accurately the manual measurement instrument in breakaway source automatically.
Summary of the invention
In order to address the above problem, the invention provides a kind of can Measurement accuracy again can be accurately the mechanical trip formula torque-indicating wrench in breakaway source automatically.
A kind of mechanical trip formula torque-indicating wrench in the present invention, comprise ratchet head and boosting-rod, also comprise sensor, display controller, pressure regulator and mechanical lock buckle storehouse, described sensor is built in boosting-rod and is connected with ratchet head, described sensor is connected with display controller, described display controller is connected with pressure regulator, described pressure regulator bottom is provided with adjustable ring, described boosting-rod middle part is provided with mechanical lock buckle storehouse, described mechanical lock buckle storehouse comprises mechanical lock, mechanical clasps, machinery is turned round and propeller, described mechanical lock is located in machinery by mechanical clasps and turn round, described machinery is turned round and is fastened between mechanical lock and propeller.
In such scheme, described display controller comprises antenna, radio-frequency module, alarm, USB port, display, controller, A/D converter, battery compartment, keyboard and charging port, described antenna, radio-frequency module, alarm, USB port connect successively, described display is connected with controller, described A/D converter is connected with controller, described display and keyboard are located on the surface of display controller, and described battery compartment and charging port are located at the side of display controller.
In such scheme, described pressure regulator also comprises spring and snap-on, and described spring is fastened between display controller and adjustable ring by snap-on.
In such scheme, also comprise guard ring, described guard ring is looped around boosting-rod outside.
In such scheme, described display is made up of charactron.
In such scheme, described display is liquid crystal display.
In such scheme, described controller is singlechip controller.
In such scheme, described sensor is torque sensor.
Advantage of the present invention and beneficial effect are: the invention provides a kind of can Measurement accuracy again can be accurately the mechanical trip formula torque-indicating wrench in breakaway source automatically.According to the power of sensor-electric transfer principle, adopt accurate torsion torque sensor as measuring cell, change the version of former torque-indicating wrench sensor, increase mechanical button lock, sensor and mechanical afterburner system are coupled together dexterously, by the application of the advanced device such as the micro-processing of single-chip microcomputer, radio frequency, USB and new technology, reach the feature in automatic breakaway source.The design is simple in structure, and parts are few, causes that the factor of error is little, and the degree of accuracy is high, simple to operate.Sensor construction advanced person selects high-accuracy strain gauge adhesion on the elastomer being closely connected with boosting-rod with ratchet head, pieces of cloth in the same way, and wiring is rationally, highly sensitive, good linearity, certainty of measurement is high.Elastomeric design and mechanical clasps one, be connected with mechanical pressure regulator by the propeller in mechanical lock buckle storehouse, automatically breakaway source.Adopt single-chip microcomputer digital processing technology, radio-frequency module, USB port to realize automatic record, remote monitoring, can quick-setting, instant analysis inspection.Certainty of measurement is higher, more convenient to operate, has really realized high-quality, intellectuality, digitizing function.
