Advantageous effect
The present invention can simulate the actual motion state of roller, and bearing inner race is simulated with the outer rim of roller, and roller is simulated with barrel cover
Retainer, and the position for being easy to observe in barrel cover is arranged the reflective mirror of indirect labor's visual inspection or the camera shooting detected automatically is arranged
Head.
In detection process, roller, which remains, to slowly run, and the rotation fixed time interval of barrel cover opens and closes.The rotation side of barrel cover
Formula continuously can bring or take out of the roller in corresponding card slot into monitoring region equipped with reflective mirror or camera in the form of revolving round the sun
It is interior.After roller is brought into monitoring region, detection workman can observe the appearance of roller distal end, direct-view roller proximal end by reflective mirror
Appearance, and by it is lasting rotation roller outer rim stir roller continuous rotation come to carry out comprehensive mesh to the circumferential surface of roller
Inspection；Three cameras can respectively to the both ends of roller and circumferential surface carry out image taking cooperation display give between worker remotely supervise
It surveys, further can camera be acquired picture inputs computer, is carried out more to roller open defect by computer program
Accurate judgement.

Specific implementation mode
As shown in Figures 1 and 2, a kind of roller open defect auxiliary detection device of the invention, including first rotating shaft 1 and
Two shafts 2.First rotating shaft 1 therein is hollow rotating shaft and is rotatably arranged in rack that the second shaft 2 is coaxially rotatably set in
In first rotating shaft 1, first rotating shaft 1 and the second shaft 2 can rotate under the action of each self-driven mechanism respectively respectively, not do mutually
It relates to.
One end of first rotating shaft 1 is equipped with the first motor for driving first rotating shaft 1 to rotate, and the other end is fixed with roller
4.One end of second shaft 2 is equipped with worm screw section, and the other end is fixed with the barrel cover 7 for being located at 4 periphery of roller.It is close in rack
The position of people's shaft worm screw section be equipped with the worm gear of worm screw section cooperation and the second motor for driving worm gear to rotate.To
The rotation of first rotating shaft 1 and the second shaft 2 can be respectively driven by first motor and the second motor respectively.Roller 4 and barrel cover 7 are equal
Big extreme direction for taper, notch towards the barrel cover 7 of card slot 5 opens up, and first rotating shaft 1 and the second shaft 2 favour level side
To setting, it can avoid roller 6 to be detected and deviate from from card slot 5 and conducive to detection.
Multiple card slots 5 for mounting and positioning roller 6 to be detected, card are offered 7 upper edge barrel cover 7 of barrel cover is circumferentially-spaced
Slot 5 is U-shaped, and after multiple rollers 6 to be detected are separately mounted in card slot 5, circumferential surface and 4 outer rim of roller of roller 6 to be detected connect
It touches, you can drive roller 6 to be detected to revolve round the sun centered on the second shaft 2 by the rotation of the second shaft 2, some is to be detected
Roller 6 is transferred to detection zone, so that the outer rim of roller 4 is stirred the circumferential surface of roller 6 to be detected to drive by the rotation of first rotating shaft 1
6 rotation of roller to be detected, to carry out comprehensive detection to the circumferential surface of roller.The control circuit of the second motor in the present embodiment
Include with the relay for controlling the second motor fixed time interval keying function and by measuring based on the second electric motor starting number
When device so that roller to be detected 6 one by one enter detection zone, and ensure each enter detection zone roller stopped in detection zone
Certain time rotates several weeks so that testing staff or equipment fill the circumferential surface of roller 6 to be detected under the drive of 4 outer rim of roller
Sorting is surveyed, and hidden danger of quality caused by missing inspection is avoided.
The present invention can implement the detection of 6 appearance of roller to be detected by following two modes：
In embodiment 1, the position that 5 notch side of card slot is corresponded in rack is equipped with reflective mirror 3, and testing staff is located at barrel cover 7
Small end position is observed the appearance of roller distal end, the appearance of direct-view roller proximal end by reflective mirror 3, and passes through lasting rotation roller 4
Outer rim stir roller continuous rotation come to carry out comprehensive visual inspection to the circumferential surface of roller, by defective work in detection process
It takes out and sorts out.
In embodiment 2, the position that 5 notch side of card slot is corresponded in rack is equipped with for shooting 6 one end of roller to be detected
First camera 8 of image, the position that the slot bottom side of card slot 5 is corresponded in rack are equipped with for shooting roller 6 to be detected separately
The second camera 10 of one end image corresponds to card slot 5 in rack and is waited for opposite to each other in the position of the side of roller 4 equipped with shooting is used for
Detect the third camera 9 of 6 circumferential surface image of roller.Three cameras can carry out image taking to the both ends of roller and circumferential surface respectively
Worker remotely monitors between cooperation display is given, and further can camera be acquired picture inputs computer, passes through machine
Vision technique（CCD）More accurate judgement is carried out to roller open defect.Three cameras are distributed in the top of jacket casing, in cylinder
The lower section and the left and right sides of set can be arranged the filling body for inserting roller 6 to be detected into jacket casing card slot 5 and will be by three
The roller that a camera detection is crossed releases the discharging mechanism of card slot 5, connects conveyer belt at the rear of discharging mechanism, on the conveyor belt
If the defective work output mechanism for releasing defective work, after detecting substandard product, by reading the second motor
In counter to determine the position of defective work, in the defective work by being discharged by defective work in conveyer belt transmission process
The substandard product is released conveyer belt by mechanism, to ensure to meet testing requirements from the product of the normal discharge of conveyer belt.
