The present invention is achieved by the following technical solutions:
A kind of multi-functional super large torque standard device, there is a pedestal fixing with ground, three support members, three support members are separately fixed above before, during and after pedestal, and wherein, the support member in front is high accuracy support member, middle support member is medium accuracy support member, support member below is fixed support part, and support member connects the support standard arm of force in high precision, and standard arm of force both sides can hang standard test weight alternately;Medium accuracy support member connects and supports the balance arm of force, and balance arm of force down either side is respectively arranged with a set of evens up mechanism.
Three support members being fixed on pedestal are located along the same line.Even up mechanism and be fixed on ground, and be connected formation revolute pair by pin with balance arm of force end.
When using as dead weight type safe standard set-up, fixing between the described standard arm of force with the balance arm of force is connected tested sensor, is formed between the standard arm of force peace weighing apparatus arm of force and be rigidly connected, and the standard arm of force peace weighing apparatus arm of force can while around the rotation of respective central supported.
When using as reference formula standard set-up, between the described balance arm of force with fixing support, concatenate reference sensor and tested sensor, formed between the balance arm of force and fixing support and be rigidly connected.
Compared with prior art, the invention has the beneficial effects as follows: the multi-functional super large torque standard device of the present invention can realize dead weight type safe torque standard device and reference two kinds of functions of formula torque standard device, high accuracy 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, space is taken up an area in saving construction cost cost, saving, improve the service efficiency of device, promote the practical value of ultra-large type torque standard device.The most important thing is to protect the dead weight type safe torque standard device of reference level, accomplish that the torque sensor of different accuracy grade carries out transmission of quantity value respectively on dead weight type safe and reference formula.
Brief description
Fig. 1 is the structural representation of the multi-functional super large torque standard device of the present invention.
Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings:
The one multi-functional super large torque standard device of the present invention can realize dead weight type safe torque standard device and reference two kinds of functions of formula torque standard device, high accuracy 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, space is taken up an area in saving construction cost cost, saving, improve the service efficiency of device, promote the practical value of ultra-large type torque standard device.The most important thing is to protect the dead weight type safe torque standard device of reference level, accomplish that the torque sensor of different accuracy grade carries out transmission of quantity value respectively on dead weight type safe and reference formula.
The specific embodiment of the present invention is as follows:
As it is shown in figure 1, a kind of multi-functional super large torque standard device, including the 4th, standard test weight the 1st, counterweight hook the 2nd, the standard arm of force the 3rd, support member balances the arm of force the 6th, hold-down support the 9th, evens up mechanism 10 and pedestal 11.
Pedestal 11 and ground are fixed.Being fixed with three support members 4 on it, forefront is high accuracy support member, and centre is medium accuracy support member, is backmost fixed support part.Three support members 4 are non-interchangeable.Must assure that three support members 4 are located along the same line.
Support member is used for supporting the standard arm of force 3 in high precision.The frictional force that this support member produces is minimum, almost nil, does not constitute 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 side standard test weight 1 will be suspended, and opposite side standard test weight 1 is placed in ground, completely disengaged with the standard arm of force 3.
Medium accuracy support member is used for supporting the balance arm of force.It is bigger that this supports the frictional force producing.Balance arm of force down either side is respectively arranged with a set of evens up mechanism 10.Even up mechanism 10 and be fixed on ground.Can be connected by pin and form revolute pair with balance arm of force end.
When using as dead weight type safe standard set-up, tested sensor 5 two ends are fixed be connected with the standard arm of force 3 and the balance arm of force 6.And guarantee there is no any connection between the balance arm of force 3 with fixing support.Now, is formed and be rigidly connected between the standard arm of force 3 and the balance arm of force 6, can be simultaneously around the rotation of respective central supported.
Examine and determine according to torque sensor and require, select side standard test weight 1 to load and hang on the standard arm of force 3, be simultaneously connected with opposite side and even up mechanism 10 and the balance arm of force 6.When the standard arm of force 3 is affected 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 are formed will act on tested torque sensor 5.
As when using with reference to formula standard set-up, the balance arm of force the 3rd, reference sensor the 7th, tested sensor 8 is connected with fixing support.And guarantee there is no any connection between the standard arm of force 3 with the balance arm of force 6.Now, balance the arm of force 3 and fixing support between is formed and is rigidly connected, in the case of non-stress, the balance arm of force 6 supports rotatable with fixing or move.
In use, requiring according to sensor test, selecting the side balance arm of force 3 to be connected with evening up mechanism 10, opposite side completely disengages from.Driving is evened up mechanism 10 and is pulled the balance arm of force 6.Now produced moment of torsion simultaneously acts on reference sensor 7 and tested sensor 8.According to reference sensor data, tested sensor 8 is examined and determine.
Meanwhile, reference torque sensor 5 is also to carry out after high accuracy measures biography on the dead weight type safe torque standard device of device front end, is connected on latter half with reference to carrying out medium accuracy calibration operation on formula torque standard device.
