Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
The multi-functional super large torque standard device of one of the present invention can realize dead weight type safe torque standard device and reference formula torque standard device two kinds of functions, high precision grade transmission of quantity value can be carried out as standard apparatus, the torque sensor gage work of daily medium accuracy grade can be carried out again as equipment, saving construction cost cost, saving take up an area space, improve the service efficiency of device, promote the practical value of ultra-large type torque standard device.The most important thing is the dead weight type safe torque standard device protecting reference level, accomplish that the torque sensor of different accuracy grade carries out transmission of quantity value at dead weight type safe with reference in formula respectively.
Specific embodiments of the invention are as follows:
As shown in Figure 1, a kind of multi-functional super large torque standard device, comprises standard test weight 1, counterweight hook 2, the standard arm of force 3, support component 4, the balance arm of force 6, hold-down support 9, evens up mechanism 10 and pedestal 11.
Pedestal 11 and ground are fixed.It is fixed with three support components 4, forefront is high precision support component, and centre is medium accuracy support component, is backmost fixed support part.Three support components 4 are not interchangeable.Must ensure that three support components 4 are located along the same line.
High precision support component is for supporting the standard arm of force 3.The friction force that this support component produces is minimum, almost nil, does not form impact to standard torque.The standard arm of force 3 both sides can hang standard test weight 1 alternately.Standard test weight 1 is positioned at standard arm of force down either side.In use, only have side standard test weight 1 to be suspended, opposite side standard test weight 1 is placed in ground, throws off completely with the standard arm of force 3.
Medium accuracy support component is used for the balance support arm of force.It is larger that this supports the friction force produced.Balance arm of force down either side respectively has a set ofly evens up mechanism 10.Even up mechanism 10 and be fixed on ground.Connect by pin and form revolute pair with balance arm of force end.
When using as dead weight type safe standard set-up, by tested sensor 5 two ends and the standard arm of force 3 with balance the arm of force 6 and be fixedly connected with.And guarantee balance the arm of force 3 with between fixed support without any being connected.Now, formed between the standard arm of force 3 and the balance arm of force 6 and be rigidly connected, can rotate around respective central supported simultaneously.
According to torque sensor calibrating requirement, select side standard test weight 1 to load hanging on the standard arm of force 3, connect opposite side simultaneously and even up mechanism 10 and the balance arm of force 6.When the standard arm of force 3 affects inclination by standard test weight 1, drive and even up mechanism 10, pull the balance arm of force 6, finally make the standard arm of force 3 keep horizontal level.The standard torque that now standard test weight 1 and the standard arm of force 3 form will act on tested torque sensor 5.
As when using with reference to formula standard set-up, the arm of force 3 will be balanced, reference sensor 7, tested sensor 8 connect with fixed support.And guarantee between the standard arm of force 3 with the balance arm of force 6 without any being connected.Now, formed and be rigidly connected between the balance arm of force 3 and fixed support, in non-stress situation, the balance arm of force 6 and fixed support are not rotatable or mobile.
In use, according to sensor test requirement, select the side balance arm of force 3 and even up mechanism 10 and be connected, opposite side departs from completely.Driving is evened up mechanism 10 and is pulled the balance arm of force 6.Now produced moment of torsion acts on reference sensor 7 and tested sensor 8 simultaneously.According to reference sensor data, tested sensor 8 is examined and determine.
Meanwhile, reference torque sensor 5 is also carry out high precision amount biography on the dead weight type safe torque standard device of device front end after, is connected on latter half and carries out medium accuracy calibration operation with reference on formula torque standard device.
