A sensor is installed inside a fixing frame, an adjusting block is arranged between the sensor and the fixing frame, the fixing frame is filled with buffering particles, the sensor is in contact with the buffering particles in the fixing frame, the upper portion of the sensor is attached to the upper portion of the fixing frame, and the lower end face of the fixing frame is provided with an adjusting screw for adjusting the attached degree between the sensor and the upper portion of the fixing frame. The upper end of the sensor is sleeved with a connecting rod, the lower end of the connecting rod is connected to the sensor, and the upper end of the connecting rod is connected with a testing tool connector. To ensure that the connecting rod keeps stable when working, a bearing is arranged on the connecting rod in a sleeved mode, and the bearing is fixed on a main machine body. The other end of the sensor is connected with a brake device, and therefore the whole mechanism is connected completely from top to bottom. The output torque of a torque tool to be tested can be tested, and the problem that when a common sensor mechanism works, connection disengaging or connection instability caused by vibration of equipment to be tested and other reasons affect a testing result is solved.
Description
Technical field
The present invention relates to a kind of torsion-testing apparatus, the mounting structure of torque sensor in especially a kind of torsion-testing apparatus.
Background technology
What the torsion-testing equipment of current main-stream adopted is the torsion-testing apparatus of simulation bolt type, abroad have and produce the torquer that adopts fluid pressure type braking, no matter adopt which kind of mode, the mechanical mismatch error that the vibration that sensor all can form because of the deviation coordinating between machinery or action after installation causes, finally has influence on the stability, repeatability of actual test number and data etc.
Use the client of torque tool generally higher to the accuracy requirement of equipment, after long-term test, traditional torque sensor mounting structure unavoidably can produce the deviation of test data, and such deviation can be more and more serious, and such situation is completely unacceptable.Therefore, need to adopt a kind of revocable floating type sensor fixing structure, the right alignment of equipment in action guaranteed in closely cooperating of the parts such as the bearing of apolegamy and main machine frame, and is difficult for causing deviation because of the vibration of test generation.Test connecting link has connected sensor and instrument to be measured, and sensor does not directly contact with instrument to be measured, avoids instrument to produce improper behaviour at that time, can not be subject to the correctness that mechanical deviation that external impacts causes has influence on final test data because of sensor.
Summary of the invention
The present invention will provide a kind of floating torsion sensor fixing structure, in order to meet market for a kind of equipment that can stable detection torque tool, the machinery that error when this equipment can solve machinery assembling or the vibration in action form coordinates change or long-term use to cause mechanical wear to cause the incorrect technical matters of final test data.
For achieving the above object, technical scheme of the present invention is: a kind of floating torsion sensor fixing structure, comprise sensor, fixed frame, be characterized in: installation of sensors is in fixed frame, between sensor and fixed frame, be provided with regulating block, buffering particle is housed in fixed frame, sensor contacts with the buffering Particle Phase in fixed frame, and sensor top is attached to fixed frame top, and fixed frame lower surface is provided with for regulating the set screw of the tightening degree on sensor and fixed frame top.
Fixed frame is fixed on main body, and a connecting link is equipped with on fixed frame top, and connecting link lower end is connected with the top connection of sensor, the connector that connecting link upper end is instrument to be measured, and on described connecting link, cover has bearing, and bearing is fixed on main body.The lower end interface of sensor is connected with electronic torque charger.
Effect of the present invention is: the present invention has introduced a kind of adjustable floating type sensor attachment mechanism, this mechanism can make up trickle machine error by buffering particle, once this error, acquire a certain degree, can adjust by adjusting set screw, thus the stability of assurance Liao Gai data that mechanism surveys.Use better simply machinery, adopt more conveniently installation method, mechanical deviation in the time of can realizing assembling, the mechanical deviation that impact causes, the deviation that instrument coordinates the inconsistent deviation causing and long period of operation equipment to bring with the machinery of equipment interface can be made up and be revised, and have guaranteed to detect correctness and the stability of data.
Accompanying drawing explanation
Fig. 1 is structure cut-open view of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described further.
As shown in Figure 1, floating torsion sensor fixing structure of the present invention, comprises sensor 6, fixed frame 3, buffering particle 7, connecting link 2, set screw 5, bearing 1, main body 4.
Sensor 6 is arranged in fixed frame 3, on sensor 6, be fixed with regulating block, sensor 6 is placed on fixed frame 3, and sensor 6 is placed with buffering particle 7 with fixed frame 3 contact positions, whole fixed frame 3 is fixed on main body 4, determines frame 3 lower surfaces and is provided with set screw 5.Turn set screw 5, touch the top of sensor 6 and the top of fixed frame 3, thereby has realized the fixing object of sensor 6.From legend, the degree being adjacent to depends on the degree that set screw 5 screws.On sensor 6, interface is connected with a connecting link 2, the other end of connecting link 2 can connect instrument to be measured or other joints, on connecting link 2, cover has a bearing 1, bearing 1 is fixed on main body 4, thereby has guaranteed that connecting link 2 is free to rotate and can not cause mechanical bias because of external vibratory impulse.The direct connecting electronic torque loading device 8 in below of sensor 6.When testing, due to external reason cause can not be in full accord between each mechanical interface realize mechanical connection, and then when moment of torsion transmission between sensor 6 and product to be tested and sensor 6 and electronic torque charger 8 is produced to deviation, existence due to buffering particle 7, will be by producing deformation after the external force of certainly experiencing, the characteristic that after external force disappears, deformation disappears, implements to make up to this mechanical shift deviation.Thereby the object that has reached correctly, stably execution of instrument to be measured has been detected.
Floating torsion sensor fixing structure of the present invention, by adding of buffering particle 7, making up of equipment error that minor deviations is caused is provided, when external impacts such as sensor 6 are vibrated or the machinery while operating each time coordinates not quite identical and produces deviation, can make integral mechanical structure and mechanical contraposition that permanent skew can not occur because of the existence of buffering particle 7, only to change in allowed limits, and after this external force is eliminated, change has reply to a certain degree, thereby guarantees to detect the correctness of data.On the other hand, when this mechanical bias is increased to a certain degree, can carry out whole adjustment by set screw 5, sensor 6 is the degree of tightening with fixed block by set screw 5 adjustment, with this, come, by adjusting this, be close to degree, and the buffering particle 7 of sensor 6 belows, the incomplete cooperation of mechanical interface in test process can effectively be avoided, the impact that the factors such as vibration of instrument to be measured cause test result.By adding of two above specific functions, can greatly improve the drawback that traditional fixed sensor assembly structure brings.
