Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, hereinafter will be described in detail to embodiment of the present utility model by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Set forth a lot of detail in the following description so that fully understand the utility model; but; the utility model can also adopt other to be different from mode described here to implement, and therefore, protection domain of the present utility model is not by the restriction of following public specific embodiment.
Below in conjunction with accompanying drawing, the torsion spring torque test calibration device described in some embodiments of the utility model is described.
As shown in Figure 1, the torsion spring torque test calibration device that the utility model provides, comprising: mount pad 2 (as shown in Figure 3); Motor 1, is fixedly mounted on mount pad 2; Survey square instrument 3 (as shown in Figure 3), be positioned at the rear side of motor 1 and be fixedly mounted on mount pad 2; Be arranged on the torsion spring 41 (as shown in Figure 2) of motor 1 inside, the rotor of torsion spring 41 and motor 1 is hinged, when driving circuit drive motor 1 is selected, realizes torsion spring 41 and rotates with identical angular velocity with the rotor of motor 1; With shaft coupling 42 (as shown in Figure 3 and Figure 4), connect torsion spring 41 and survey square instrument 3.
The torsion spring torque test calibration device that the utility model provides, between motor 1 and survey square instrument 3, torsion spring 41 and shaft coupling 42 are installed, by demarcating torsion spring, realizing measuring the stiffness coefficient of torsion spring reality and being revised the coefficient of electricity consumption dynamo-electric stream calculation motor output torque formula by the stiffness coefficient measured.Torsion spring twist mechanism reduces power, the reduction pulser power consumption of motor 1 rotor swing actual consumption.
In addition, the utility model above-described embodiment provide torsion spring torque test calibration device also can have following additional technical characteristic:
Preferably, torsion spring torque test calibration device also comprises: rotary transformer (belonging to position transducer), be arranged on motor 1 inner, for detecting the anglec of rotation of the rotor of motor 1, because the rotor of motor rotates with identical angular velocity with torsion spring 41, and then the torsion spring twist mechanism anglec of rotation can be obtained.
Rotated in certain angular range by drive plate drive motor 1 rotor, the preferred half degree in rotational angle interval (can adjust rotational angle interval as required), motor 1 rotor moves with identical angular velocity with torsion spring.Motor 1 rotational angle is detected by rotary transformer.
Motor 1 rotational angle and physical location are fed back by rotary transformer, according to half degree (rotational angle interval can be adjusted as required) drive motor 1 rotor turns, due to torsion spring twist mechanism and rotor hinged, and then drive torsion spring twist mechanism to reverse, the torque value that record torque measuring square instrument 3 shows.
Take windup-degree as horizontal ordinate, with the torque value of torque gauge display for ordinate, draw windup-degree and record the relation curve that torque value changes, the torsion spring torsion device output torque added in pulse producer is linear change.When torsion spring length is certain, obtain the slope of this straight line, simply can be interpreted as the stiffness coefficient of torsion spring.
Disconnect shaft coupling, the numerical value that drive motor 1 utilizes rotary transformer to react, obtains the windup-degree of torsion spring twist mechanism, now, by the Q shaft current of motor 1, by conversion relation, also can draw the variation relation curve between angle and the torque of Q shaft current.

In electronic circuit, the Measurement accuracy of current value is a difficult point.Measure electric current exactly, just can obtain relatively accurate torque, and then calculate motor 1 power operationally.
The torsion spring added can be used as transmission shaft between motor 1 to rotor.Due to down-hole narrow space, at work, this can simplify pulse producer structure, for other arrangements of elements provide space after improving.
For torsion spring mechanism, in working rotor angle range, along with the change of torsion spring corner, torsion spring output torque value and waterpower are preferably close to the torque value of rotor.
When torsion spring mechanism, under the low hunting frequency of rotor of pulser (i.e. motor 1), motor 1 Driving Torque is mainly used in the effect of offsetting waterpower torque; For the situation that waterpower torque value suffered by rotor is linear change substantially, can basic neutralisation waterpower torque value after interpolation torsion spring.Motor 1 torque can be reduced, and then reduce the power demand to motor 1, realize reducing motor 1 diameter and length, make pulser miniaturization become possibility.
When expansion working rotor angle range, waterpower torque will be caused with the non-monotonic situation of change of corner, now also can add torsion spring device, but effect is slightly poor.
Particularly, as shown in Figure 3, torsion spring torque test calibration device also comprises: fixed head 61 and adjustment screw rod 62, and motor 1 is fixed on mount pad 2 by fixed head 61 and adjustment screw rod 62.
Wherein, fixed head comprises V-arrangement base plate and V-arrangement cover plate.
Certainly, fixed head 61 also can be the fixture of other structures, also can realize the object of the application, not repeat them here, but should belong in the protection domain of the application.
Particularly, as shown in Figure 3, mount pad 2 comprises: base plate, and motor 1 is arranged on the upper surface of base plate; And side plate, be positioned at the rear side of survey square instrument 3 and be fixed on base plate, and survey square instrument 3 is fixed on side plate.
In sum, the torsion spring torque test calibration device that the utility model provides, between motor and survey square instrument, torsion spring and shaft coupling are installed, by demarcating torsion spring, realizing measuring the stiffness coefficient of torsion spring reality and being revised the coefficient of electricity consumption dynamo-electric stream calculation motor output torque formula by the stiffness coefficient measured.Torsion spring twist mechanism reduces power, the reduction pulser power consumption that rotor swings actual consumption.
Known by testing, pulse producer in working order under, waterpower torque is influential to rotor, and suffered by rotor, moment of torsion distributes substantially in the same direction, and the method therefore by adding torsion spring device offsets partial torque, reduces the output of power of motor and moment of torsion.
Rotor and torsion spring mechanism with the use of, namely make good use of torsion spring, make rotor close trend torque and the torque balance of torsion spring, greatly can reduce motor output torque, and then reduction power of motor.
After torsion spring design machines, be assembled into torsion spring mechanism.Before real work, its torsion spring mechanism physical characteristics needs actual measurement to obtain; Drive the motor output torque of rotor also to need to draw by measuring internal current, both are combined, and can calibrate motor output torque.
