Abstract
The invention provides a bearing ball surface flatness detection apparatus based on sound waves. The apparatus comprises a bending raceway, sound sensors and a control box, the bending raceway comprises an inlet portion, a bending portion, and an outlet portion, the total length of the bending portion is greater than 30 times of the diameter of a to-be-detected bearing ball, the bottom of the bending portion is the equipped with a plurality of sound sensors, signals of the plurality of sound sensors are connected to the control box, and the control box performs smoothness judgment and outputs a determination result to a bearing detection control system according to the sound signals received by the sound sensors. According to the apparatus, high-precision and even ultrahigh-precision detection of the bearing ball can be conducted based on analysis of the sound waves through the setting of the sound sensors and the bending raceway.
Description
Technical field
The present invention relates to a kind of bearing ball surfacing detection means based on sound wave.
Background technology
It is mostly to adopt vision-based detection for the detection of bearing ball surfacing in prior art, then vision-based detection
Seriously limited by precision in automation.
The content of the invention
To solve above-mentioned technical problem, the invention provides a kind of bearing ball surfacing detection dress based on sound wave
Put, the bearing ball surfacing detection means of sound wave should be based on by sound transducer, the setting of bending raceway, sound can be based on
The analysis of ripple carries out the high accuracy even detection of superhigh precision to bearing ball.
The present invention is achieved by the following technical programs.
A kind of bearing ball surfacing detection means based on sound wave that the present invention is provided, including bending raceway, sound
Sensor, control box；The bending raceway is divided into oral area, bend, export department, and wherein bend total length is more than to be detected
The thirtyfold of bearing ball diameter；The bend bottom is equipped with multiple sound transducers, multiple sound transducer signal difference
It is connected to control box；The control box receives voice signal and carries out stationarity judgement and to Bearing testing according to sound transducer
Control system exports judged result.
The bend is that multiple bends for bending back and forth, straight portion interlock track, and the sound transducer is arranged on every
The bottom position in the straight portion of one bend.
There is arc-shaped groove in the section-top of the bend, its circular arc is the semi arch of positive round.
The plurality of sound transducer accesses to control box from the inlet portion that bending is rolled into export department's distribution sequence.
The beneficial effects of the present invention is：By sound transducer, the setting of bending raceway, the analysis that can be based on sound wave is right
Bearing ball carries out the high accuracy even detection of superhigh precision.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
In figure：11- inlet portions, 12- bends, 13- export departments, 21- sound transducers, 22- control box.
Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
A kind of bearing ball surfacing detection means based on sound wave as shown in Figure 1, including bending raceway, sound biography
Sensor 21, control box 22；The bending raceway is divided into oral area 11, bend 12, export department 13, and the wherein total length of bend 12 is big
In the thirtyfold of bearing ball diameter to be detected；The bottom of the bend 12 is equipped with multiple sound transducers 21, multiple sound
The signal of sensor 21 is respectively connecting to control box 22；The control box 22 receives voice signal and carries out according to sound transducer 21
Stationarity judges and exports judged result to Bearing testing control system.
The bend 12 is that multiple bends for bending back and forth, straight portion interlock track, and the sound transducer 21 is installed
In the bottom position in the straight portion of each bend 12.
There is arc-shaped groove in the section-top of the bend 12, its circular arc is the semi arch of positive round.
The plurality of sound transducer 21 accesses to control from the inlet portion 11 that bending is rolled into the distribution sequence of export department 13
Box 22.
Thus, when bearing ball enters bend 12 by inlet portion 11, it is assumed that the sound that multiple sound transducers 21 are received
Ripple quotation marks are sequentially followed successively by a1、a2、a3、a4、a5、a6, then a1、a2、a3、a4、a5、a6Between according to distance and sequential is fixed, if rolling
Pearl does not have flaw, then a1、a2、a3、a4、a5、a6Should be completely the same, if ball has flaw, can be uneven in rolling process
Surely, a1、a2、a3、a4、a5、a6The voice signal collected is analog signal, can greatly be amplified, therefore can be by contrasting a1、
a2、a3、a4、a5、a6And note abnormalities, and Doppler effect principle can be based on, flaw ball position is analyzed, when adding system
Sequence then accurately can find on flaw ball.
