According to the motor service life testing tool, the motor can be reliably fixed, and the rotating speed and the working current of the motor can be monitored on real time; the working performance of the motor can be accurately analyzed according to the detection data, so that the service life of the motor can be determined; in addition, the inaccurate test caused by noise interface or falling of a welding wire due to the vibration of a motor body during testing the service life of the motor can be effectively avoided.
Description
Technical field
The present invention relates to the performance test of motor, particularly relate to the life test frock of motor.
Background technology
The most important parameter of motor is exactly the life-span of motor, in actual use, fuzzyyer failure criterion be exactly operation the regular hour after, motor can not produce noise, usual workman only by rule of thumb the Oscillation Amplitude of perception motor judge motor whether exist fault need change.
The main cause that usual motor produces noise is that the gap between bearing and axle becomes large, thus causes rotating speed to become large, occur noise etc., and this kind of problem workman can detect by rule of thumb.But the reason producing noise is not exclusively the problem because of motor itself in life test, likely also that motor body departs from fixing result in vibration processes, motor and fixing structure generation resonant impact noise, and other a variety of causes also can affect the judgement of workman to motor failure, but, the method of this failure judgement by rule of thumb cannot discover the less fault of existence, the serviceable life of motor cannot be predicted, can only change immediately once break down, therefore, how to motor life make judge accurately particularly important.
Summary of the invention
In view of the deficiency that prior art exists, the invention provides a kind of test fixture accurately testing motor life.
In order to realize above-mentioned object, present invention employs following technical scheme:
A kind of motor life test fixture, comprising:
Base, for placing motor;
Pressing mechanism, comprises connecting rod and extension spring, for motor being pressed on the upper surface of described base;
Testing circuit, is connected to input and the input end of motor, for rotating speed and the working current of Real-Time Monitoring motor;
The stiff end of described connecting rod is rotatably fixed on described base, and one end of described extension spring is fixed, and the other end of described extension spring is fixed on described connecting rod, makes the free end of described connecting rod towards described base by pressure motor.
Wherein, motor life test fixture also comprises pressing plate, and described pressing plate is fixed on the free end of described connecting rod, for contacting with the upper surface face of motor.
Wherein, described base comprises the vertical portion being vertical at its Width both sides, is equipped with rotating shaft between two described vertical portions, and the stiff end of described connecting rod is connected in described rotating shaft.
Wherein, motor life test fixture also comprises the retainer plate of annular, and described fixed trap is located at the surrounding of motor and relative with described base fixing.
Wherein, motor life test fixture also comprises adhered layer, and motor is pasted onto on described base by described adhered layer.
Wherein, in an obtuse angle bending in the middle part of described connecting rod, described extension spring is fixed on the bending place of described connecting rod.
The present invention devises a kind of motor life test fixture, can reliably fixing motor, and the rotating speed of Real-Time Monitoring motor and working current, the serviceability of motor can be analyzed exactly by detecting data, judge the mission life of motor with this, and effectively can avoid in motor life test process that to shake the come off test that causes of the noise interference that causes or bonding wire inaccurate because of non-motor body.
Accompanying drawing explanation
Fig. 1 is the partial cross structural representation of the motor life test fixture of the embodiment of the present invention.
Fig. 2 is another view of the motor life test fixture of the embodiment of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Shown in composition graphs 1 and Fig. 2, motor life test fixture of the present invention comprises: base 10, pressing mechanism 20 and testing circuit (not shown), and wherein base 10 is for placing motor 1; Pressing mechanism 20 comprises connecting rod 21 and extension spring 23, for motor 1 is pressed on base 10 upper surface; Testing circuit is connected to input and the input end of motor 1, for rotating speed and the working current of Real-Time Monitoring motor; The stiff end of connecting rod 21 is rotatably fixed on base 10, and one end of extension spring 23 is fixed, and the other end of extension spring 23 is fixed on connecting rod 21, makes the free end of connecting rod 21 towards base 10 by pressure motor 1.
By real-time detection, if the change of more than 30% occurs for the rotating speed of motor 1 and electric current, then judge that its running status is bad, need repairing, prevent from occurring chance failure in the course of work.
In order to improve the pressing effect of connecting rod 21, connecting rod 21 is also fixed with pressing plate 22 by the free end side of pressure motor 1, pressing plate 22 contacts with the upper surface face of motor 1, increase the lifting surface area of motor 1, make it stressed evenly, reduce motor 1 bob causes on base 10 vibrations interference in energising test process, and avoid motor 1 bonding wire in test process and come off.
Particularly, base 10 comprise be vertical at its Width both sides vertical portion 11,11, two, vertical portion between be equipped with rotating shaft 24, the stiff end of connecting rod 21 is connected in rotating shaft 24.
The retainer plate 25 of annular is set in the surrounding of motor 1, and relative with base 10 fixing, and retainer plate 25 specifically can be fixed by modes such as screw or latch connections.By such setting, motor 1 displacement in the horizontal direction can be limited, further increase fixing reliability.Meanwhile, motor 1 is also pasted onto on base 10 by adhered layer 26.Further avoid motor body in vibration processes, depart from base 10, with base 10, resonant impact noise occurs, affect the judgement to experimental result.
In an obtuse angle bending in the middle part of the connecting rod 21 of the present embodiment, extension spring 23 is fixed on the bending place of connecting rod 21, substantially reduces the length of connecting rod 21, preferred bending angle is 150 °.When testing, first lift pressing plate 22, motor 1 is pasted onto the corresponding site on base 10 in retainer plate 25, then pressing plate 22 is unclamped, under the effect of extension spring 23, pressing plate presses pressure motor 1 towards base 10 direction, and finally connecting testing circuit can carry out life test.
Motor life test fixture of the present invention, can reliably fixing motor, its degree of freedom is limited in level and vertical direction, and the rotating speed of energy Real-Time Monitoring motor and working current, the serviceability of motor can be analyzed exactly by detecting data, judge the mission life of motor with this, and effectively can avoid in motor life test process that to shake the come off test that causes of the noise interference that causes or bonding wire inaccurate because of non-motor body.
The above is only the embodiment of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of the application.
