A kind of thread detecting device, including rotating platform, several stations are provided on the rotating platform, and the station is used
In placing screw element to be measured, rotating platform surrounding correspond to be disposed at each station optoelectronic switch, thread measurement mechanism,
Mark of conformity mechanism, unqualified exclusion mechanism, the optoelectronic switch judge whether there is screw element to be measured on station, the screw thread inspection
It surveys mechanism screw element to be measured is carried out to detect whether qualification, qualified screw element is marked in the mark of conformity mechanism, described
Unqualified exclusion mechanism excludes unqualified screw element.
Further, the thread measurement mechanism includes the thread gage driven by servo motor, the thread gage and servo electricity
Pass through double shaft coupling flexible connections between machine.
Further, the thread measurement mechanism is driven by the cylinder lifting, and the cylinder is respectively set with thread measurement mechanism
In bracket two sides, thread measurement mechanism includes connecting plate, and the connecting plate is slidably connected with the guide rail on bracket.
Further, the thread gage is arranged in thread gage collet, passes through between the thread gage collet and double shaft couplings
Flexible joint connection, the flexible joint are arranged in connecting plate.
Further, the mark of conformity mechanism includes the marking pen driven by slider cylinder.
Further, the unqualified mechanism that excludes includes the finger cylinder driven by three axis cylinders, and the three axis cylinder is logical
It crosses rodless cylinder driving to move horizontally, so that the finger cylinder be made to move back and forth above station and above collecting receptacle.
After adopting the above scheme, the utility model compared with prior art, has the advantage that
The detection to screw element to be measured is completed by automatic process and is selected, to improve detection efficiency；When detecting
Even if there are micro deviations for the alignment between thread gage and screw element to be measured, can also make to have detected by the adjustment of flexible joint
At without damaging screw element and thread gage.

Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
As shown, a kind of thread detecting device, including rotating platform 1, several stations 2, work are provided on rotating platform 1
Position 2 is for placing screw element to be measured, and the setting of station 2 should be taken into account the position of screw element to be measured in subsequent each step,
1 surrounding of rotating platform, which corresponds to, is disposed with optoelectronic switch 3, thread measurement mechanism 4, mark of conformity mechanism, no at each station 2
Qualification excludes mechanism, and wherein optoelectronic switch 3 judge whether there is screw element to be measured on correspondence station 2, judges rotating platform 1 with this
Whether continue to rotate.
Thread measurement mechanism 4 carries out screw element to be measured to detect whether qualification, thus feed back to control system drive it is next
Station 2 should be by mark of conformity mechanism action still by unqualified exclusion mechanism action.Thread measurement mechanism 4 includes servo motor
41, double shaft couplings 42, connecting plate 43, thread gage collet 44, thread gage 45, flexible joint 46, thread gage 45 are arranged in thread gage
It in collet 44, is connected between thread gage collet 44 and double shaft couplings 42 by flexible joint 46, the setting of flexible joint 46 is connecting
In plate 43, the other end of double shaft couplings 42 is connect with servo motor 41.Such mode make thread gage 45 with screw element pair to be measured
When connecing, certain offset can permit, to avoid the damage that will cause in the case of rigid connection.
Thread measurement mechanism 4 is driven by the cylinder lifting, and cylinder and thread measurement mechanism 4 are separately positioned on 10 two sides of bracket,
Thread measurement mechanism 4 is slidably connected by connecting plate 43 and the guide rail on bracket 10, presets thread measurement by displacement sensor
The adjustable height of mechanism 4.
Mark of conformity mechanism includes the marking pen 6 driven by slider cylinder 5, when marking pen 6 stretches out, to qualified after detection
Screw element is marked.
Unqualified exclusion mechanism includes the finger cylinder 8 driven by three axis cylinders 7, and finger cylinder 8 can carry out screw element
Clamping, and three axis cylinders 7 driving finger cylinder 8 is gone up and down, three axis cylinders 7 are moved horizontally by the driving of rodless cylinder 9, thus
Move back and forth the finger cylinder 8 above station 2 and above collecting receptacle.
The course of work of whole device is as follows: being put into screw element to be measured in most initial station 2 first, rotating platform 1 rotates
Screw element to be measured is sent at optoelectronic switch 3, optoelectronic switch 3 carries out station 2 to have detected whether that screw element to be measured is located at station 2
On, it is to suspend rotating platform 1 without if if testing result, if it is having, screw element to be measured is transferred to next link, uses screw thread
Testing agency 4 is detected to whether screw element to be measured progress screw thread meets design requirement, and cylinder drives under thread measurement mechanism 4
After drop, the driving of servo motor 41 makes thread gage 45 be transferred to screw element to be measured, after one-time detection is set by program or is detected twice,
If detection rear thread part meets design requirement, marking pen 6 is driven to stretch out by the slider cylinder 5 of mark of conformity mechanism, it is right
Detection rear thread part marks, and shows that the screw element meets the requirements, screw element if it does not meet the requirements, then in mark of conformity
At next unqualified exclusion mechanism of mechanism, finger cylinder 8 is driven to decline by three axis cylinders 7, finger cylinder 8 clamps screw thread
Three axis cylinders 7 go up after part, are then moved to above discard bin by rodless cylinder 9 with dynamic triaxial cylinder 7, by unqualified screw thread
Part lose into.
Above are only specific embodiment of the utility model, at the same involved in all the utility model as " it is upper and lower, left,
The words such as right, centre " are only used as to refer to, not absolute limit, and all changes that unsubstantiality is carried out using the utility model should all
It falls into the category of infringing the protection scope of the present invention.
