Abstract
The utility model relates to an assembly for a torque wrench detecting system, in particular to a sensor switching structure for a torque wrench detecting system. The sensor switching structure comprises a switchover shaft sleeve. A blind hole which is matched with an output shaft of a speed reducer is formed in the lower end of the switchover shaft sleeve, a key slot is formed in the blind hole, the switchover shaft sleeve is arranged on the output shaft of the speed reducer via the blind hole and the key slot, and the upper end of the switchover shaft sleeve is detachably connected with a sensor. The sensor switching structure has the advantages that the sensor is connected with the output shaft of the speed reducer by the switchover shaft sleeve, so that only the sensor needs to be taken down from the switchover shaft sleeve when replaced; the switchover shaft sleeve is detachably connected with the sensor, so that the sensor switching structure brings convenience for mounting and detaching the sensor, the labor intensity can be reduced, and required sensor replacing time can be saved.
Description
Technical field
The utility model relates to a kind of assembly of torque spanner detection system, is specifically related to a kind of sensor transformational structure for torque spanner detection system.
Background technology
Torque spanner is a kind of measurement instrument of tightening with torque measuring mechanism, for fastening screw screw bolt and nut, and can measure the torque value while tightening, is therefore a kind of important utensil of controlling assembly precision; According to used power source, torque spanner is generally divided into manual, electronic, the pneumatic and large class of hydraulic pressure four; The reasons such as wherein manually torque spanner is simple in structure because of it, cheap and easy to use, application surface is the widest.
Along with China's industrial expansion, industrial technical level is more and more higher, also more and more higher to the requirement of product quality, and this makes in production assembling process the requirement to assembly technology also more and more harsh; Therefore, in recent years, the utilization of torque spanner in the industries such as Mould Machining, automobile making, communications and transportation and refitting manufacture is more and more extensive, and its quantity also goes up year by year.Torque spanner, as measurement instrument, must regularly use torque spanner detection system it is exercised supervision and calibrate.In the time detecting, due to the moment of torsion range difference of detected object, so usually need in actual use more emat sensor to mate with checked object.
But in current torque spanner detection system, sensor is normally directly connected with the output shaft of reductor, for the reliability connecting, being connected of the output shaft of sensor and reductor is all more firm, so in the time of emat sensor more, also effort relatively, while particularly frequently replacing, not only labour intensity is large, and replacing speed is also slow, when waste of manpower, also stops over detection time.
So needing at present one badly can be connected sensor with speed reducer output shaft, can facilitate again the connecting device for sensor of sensor installation installation and removal.
Utility model content
Goal of the invention of the present utility model is: in existing torque spanner detection system, the problems referred to above that installation of sensors exists, provide a kind of sensor transformational structure for torque spanner detection system.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of sensor transformational structure for torque spanner detection system, comprise switching axle sleeve, described switching axle sleeve lower end is provided with the blind hole matching with speed reducer output shaft, in described blind hole, be provided with keyway, described switching axle sleeve is arranged on described speed reducer output shaft by described blind hole and described keyway, and described Coupling Shaft set upper side is connected with sensor is dismountable.By switching axle sleeve, sensor is connected with speed reducer output shaft, make in the time of emat sensor more, only sensor need to be put and takes off from Coupling Shaft, and between switching axle sleeve and sensor, be dismountable connection, so facilitated the installation and removal of sensor, when reducing labour intensity, also save the more needed time of emat sensor.
As preferred version of the present utility model, described Coupling Shaft set upper side is provided with square toes, and described sensor lower end is provided with the square hole matching with described square toes.Cooperation by square toes and square hole puts sensor setting in Coupling Shaft, further facilitated the installation and removal of sensor.
As preferred version of the present utility model, described square toes upper end arranges chamfering.In square toes upper end, chamfering being set facilitates square hole to be set on square toes.
As preferred version of the present utility model, the outside interval of described square toes be arranged with sleeve, the inwall of described sleeve matches with the outer wall of described sensor.Due to sensor in use, lower end is subject to the moment of torsion that reductor transmits by switching axle sleeve, and be subject to the reciprocal moment of torsion that tested torque spanner imposes in upper end, in actual use, because the manufacture of each equipment all exists tolerance, so in the time that reductor imposes moment of torsion, sensor is likely subject to the moment of flexure of overturning, so put the sleeve matching with sensor outer wall be set in Coupling Shaft, make sensor can bear certain upset moment of flexure, ensure the measuring accuracy of sensor.
In sum, owing to having adopted the technical solution of the utility model, the utlity model has following advantage:
By switching axle sleeve, sensor being connected with speed reducer output shaft, is dismountable connection between switching axle sleeve and sensor, so facilitated the installation and removal of sensor, when reducing labour intensity, has also saved the more needed time of emat sensor.
Other beneficial effects in embodiment of the present utility model:
Put and be arranged at the sleeve that sensor outer wall matches in Coupling Shaft, make sensor can bear certain upset moment of flexure, ensure the measuring accuracy of sensor.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
embodiment 1
As shown in the figure, a kind of sensor transformational structure for torque spanner detection system, comprise switching axle sleeve 1, described switching axle sleeve 1 lower end is provided with the blind hole 2 matching with reductor 8 output shafts, in described blind hole 2, be provided with keyway 3, described switching axle sleeve 1 is arranged on described reductor 8 output shafts by described blind hole 2 and described keyway 3, and described switching axle sleeve 1 upper end is connected with sensor 4 is dismountable.By switching axle sleeve 1, sensor 4 is connected with reductor 8 output shafts, make in the time of emat sensor 4 more, only sensor 4 need to be taken off from switching axle sleeve 1, and between switching axle sleeve 1 and sensor 4, be dismountable connection, so facilitated the installation and removal of sensor 4, when reducing labour intensity, also save the more needed time of emat sensor 4.
