The torque and angle tester has the advantages of high testing intellectualization and high measuring precise, good and accurate controllability, small torque return difference, abrasion resistance and ageing resistance.
Description
Technical field
The utility model relates to a kind of actuator moment of torsion and angle measurement instrument, belongs to automotive electronics part-testing device technical field.
Background technology
Actuator torque measurement mode is generally arm of force formula measurement as shown in Figure 1 at present.The measurement detailed process of this device is:
Torque measurement: the maximum stall torsion F (unit: N) that the test panel that step 1, tautness meter drive by actuator records that the actuator rotation produced; Step 2, utilize maximum stall torsion F (N) that the first step records and known arm of force L (M), pass through formula again: moment of torsion (Nm)=power (N) * arm of force (M) is tried to achieve the moment of torsion that actuator produces.Measure drawback: (1) survey crew is difficult to read the maximum stall torsion F that accurate tautness meter produces
1, survey crew quality will badly influence measurement result like this; (2) measuring process is comparatively loaded down with trivial details, makes the big heavy discount of efficiency of measurement.
Measurement of angle: the actuator output arm drives the test panel rotation that indicates scale, and survey crew goes out anglec of rotation a by the change calculations of total indicator reading before and after the test panel rotation then.Measure drawback: method of testing is more original, reading efficient, and error is bigger.
Summary of the invention
The purpose of this utility model provides a kind of intellectuality and high tester of measuring accuracy tested.
In order to achieve the above object, the technical solution of the utility model provides a kind of actuator moment of torsion and angle measurement instrument, comprise guide rail, be provided with support on guide rail, it is characterized in that, the two ends of actuator are located at respectively on support and the test panel, actuator connects controller, test panel and angular transducer are located at respectively on the output shaft of magnetic powder brake both sides, and angular transducer and magnetic powder brake connect data processor, and data processor connects display device.
Usually burning has the program that weaves in advance in data processor.The utility model is by regulating just controlling torque very easily of exciting curent, and torque is good linear relationship with exciting curent, is directly proportional in quite wide scope with exciting curent; Magnetic powder brake output shaft of the present utility model links to each other with test panel, when rotating, test panel will drive the magnetic powder brake rotation by output shaft, data processor collects the electric current delta data of magnetic powder brake then, calculates the moment of torsion of actuator again according to the linear relationship of magnetic powder brake torque and exciting curent.Certainly, this moment of torsion is not the actual torque value of actuator.Because some measured instrument itself has consumed in the transmittance process of power, so data processor adds that with the torque value that records the used up moment of torsion of measuring instrument is as test result; When driving the magnetic powder brake rotation, test panel also can drive the angular transducer rotation of rear end.This angular transducer is made up of connecting shaft code-wheel, data processor and a signal output system usually.When the connecting shaft code-wheel had angle displacement, data processor can calculate angle value according to the swing offset amount, at last rotation angle value is flowed to data processor with digital form; Data processor calculates the signal process that collects, and at last test data is transported to charactron and shows.
The utility model has the advantages that: test intellectuality and measuring accuracy height, have the good controllability accurately that reaches, the torque return difference is little, and is wear-resistant, ageing-resistant.
