Description
Technical field
It is more particularly to a kind of to be used to detect the horse on electronic product the present invention relates to electron product checking device technical field
Up to the device of vibration.
Background technology
At present, there are many electronic products, such as high-new electronic product of 3D cameras, smart mobile phone, tablet personal computer, because of it
With advantages such as carrying convenience, operating flexibility, cloud connection, cloud transmission, popular daily life has been rapidly permeated into, it is deep to be chased after
Hold in both hands.This electronic product can configure vibrating motor, sense operation process when being operated in order to user, have sense of touch, and different behaviour
Make that perceptibility requirement of the interface user to motor vibrations is also different, and this just needs to test the vibration performance of motor.
The currently used mode for being used to test motor vibrations is that product is placed into product fixed seat, by product with surveying
Equipment electrical connection is tried, while has the sensor for detecting motor vibrations by parts such as fixtures in product fixed seat, so as to examine
Survey the vibration performance of motor at different conditions.Such a motor vibrations test mode has the disadvantage that：
First, the interference of the factors such as sound wave in checkout area, extraneous vibration can not be shielded；
2nd, motor vibrations will can just be transmitted to sensor by parts such as fixtures, and because transducer sensitivity is higher, therefore it is examined
Measure not just caused by the part such as the vibration of motor, fixture interference vibration can also detect, cause transmit distortion, data
Read inaccurate.
The point defect of the above two causes in the test process of motor vibrations, and the test data of the identical index of identical product is consistent
Property is poor, and digital independent is unstable, and test result accuracy is poor.
The content of the invention
For disadvantages described above, it is an object of the invention to provide a kind of motor vibrations detection means, this motor vibrations detection dress
The sound wave and extraneous vibration that can be masked in checkout area are put, the test data uniformity of the identical index of identical product is good, test
As a result accuracy is high.
To achieve the above object, the technical scheme is that：
A kind of motor vibrations detection means, including：Workbench, the bottom of the workbench are provided with multiple adjustable lower margins,
The top of the workbench is installed with shielded box；The shielded box includes be hinged casing and case lid, the casing and institute

State detecting tool and be provided with product accommodating cavity, the electricity electrically connected for product with detection device is also equipped with the detecting tool
Connecting interface；The biography for being used to detect the motor vibrations being oppositely arranged with the motor of the product is also equipped with the casing
Sensor.
Wherein, the sound absorbing layer includes acoustical cotton layer.
Wherein, the sound absorbing layer also includes plank layer and the felt being arranged between the shell and the acoustical cotton layer
Layer, the felt layers are set close to the shell.
Wherein, the casing on the end face of the case lid phase folding with being equipped with sealing gasket.
Wherein, the sealing gasket is fitted on the end face of the shell, the felt layers and the plank layer.
Wherein, the both sides of the casing and the case lid are respectively provided with a folding cylinder, and the cylinder body of the folding cylinder is hinged
On the casing, the piston rod of the folding cylinder is hinged on the case lid.
Wherein, cushion blocking is provided between the casing and the workbench.
Wherein, the detecting tool includes the installing plate and bottom plate be arrangeding in parallel up and down, the installing plate and the bottom plate
Between be connected with support column, product fixed seat is fixed with the installing plate, the product accommodating cavity is arranged on the product and consolidated
In reservation, the product accommodating cavity runs through the product fixed seat up and down；The electrical connection interface is arranged on the bottom plate, institute
The position that the product accommodating cavity is corresponded on installing plate is stated provided with the through hole run through up and down.
Wherein, the position that the motor of the product is corresponded in the product fixed seat is provided with tapped through hole, the sensor
It is threadably mounted in the tapped through hole.
Wherein, the workbench is provided with control cabinet, and the detection device is arranged in the control cabinet.
After employing above-mentioned technical proposal, the beneficial effects of the invention are as follows：
Because motor vibrations detection means of the present invention includes workbench, the bottom of workbench is provided with adjustable lower margin, work
The top of platform is installed with shielded box；Shielded box includes be hinged casing and case lid, and casing and case lid include shell and patch
Close sound absorbing layer inside the shell；Be installed with the detecting tool and sensor for detecting product in casing, sensor with
The motor of product is oppositely arranged.When carrying out motor vibrations test, workbench is adjusted to equilibrium-like by each adjustable lower margin
State, workbench is touched without rocking, along with the deadweight of workbench in itself, the vibration in the external world can be effectively eliminated；Then will
Product is placed into the product accommodating cavity of detecting tool so that sensor is corresponding with the motor on product, closes shielded box, opens
Begin to test, the sound absorbing layer in shielded box can effectively absorb the noise sound wave in the external world, serve the effect of noise reduction, greatly drop
Low influence of the outside noise sound wave to test.So as to which motor vibrations test device of the present invention effectively shields and eliminated test
The sound wave and extraneous vibration of field, eliminate interference of the external environment to test result, ensure that the accuracy of each test data
And stability, really measure the Oscillation Amplitude and vibration frequency of product motor, the test data one of the identical index of identical product
Cause property is good, and the accuracy of test result is high.
Because the position of the motor of corresponding product in product fixed seat is provided with tapped through hole, sensor threads are arranged on screw thread
In through hole, sensor is directly installed in product fixed seat, it is no longer necessary to which other clamping parts are transferred, so as to which motor produces
Vibration can be directly passed to sensor, avoid the distortion that vibration is transmitted, further increase the accuracy of test result.
