Description
Technical field
The present invention relates to machining fields of measurement, and in particular to a kind of method for automatic measurement of workpiece.
Background technique
Workpiece after completion of processing, needs to detect workpiece on lathe, to whether check the workpiece that processes
It complies with standard, prevents underproof workpiece from flowing to market.
For disc type work, disc type work needs turning on the circumferential surface to go out groove, for example, to the processing of belt pulley,
Processing etc. to auto absorber piston.The detection of existing disc type work is manually by vernier caliper to disc type work circumference
The get on the bus groove that cuts out of face carries out manual measurement, and this detection method low efficiency, detection intensity is big, and cannot be to groove turning
Precision monitored in real time.
Summary of the invention
The invention is intended to provide a kind of method for automatic measurement of workpiece, to solve existing workpiece sensing manual operation low efficiency
The problem of.
In order to achieve the above objectives, basic technology scheme of the invention is as follows: a kind of method for automatic measurement of workpiece, including work
Part orients transportation resources, workpiece dynamic testing method, workpiece buffering localization method, and workpiece dynamic testing method is included in monitor station
On movement is oriented to workpiece, in moving process from the side of workpiece carry out workpiece size detection, workpiece size detection packet
It includes and workpiece size testing result is converted into laser signal by testing agency, laser signal is converted with laser range sensor
Testing result judgement is carried out for electric signal.
The principle and advantage of this programme are: the multiple steps of use successively carry out placing direction adjustment to workpiece, orientation is transported,
Positioning, dynamic detection etc. are buffered, carries out the size detection of workpiece automatically with mechanical equipment, and passes through testing agency for the inspection of workpiece
Result is fast and accurately converted to light, electric signal obtains intuitive testing result for survey, compared to by manually using vernier caliper
The detection of workpiece is carried out, detection efficiency is higher, and artificial judgement influence is small, and testing result is more objective and accurate.
Further, workpiece buffering localization method includes that the workpiece carried out before workpiece dynamic chek method positions buffering for the first time
Operation and the workpiece carried out after workpiece dynamic chek method reposition buffer operation.Using such method to workpiece into
Enter to detect it is forward and backward carry out buffering positioning so that the initial position and final position of workpiece are more quasi- in subsequent dynamic detection process
Really, it convenient for workpiece to be accurately moved to detection position and unloading position, avoids workpiece from going out from monitor station and falls.
Further, the transportation resources of workpiece orientation includes the workpiece automatic transportation behaviour carried out before the first positioning operation of workpiece
The workpiece turning directional operation made and carried out before workpiece automatic transportation operates.Workpiece turning directional operation carries out workpiece
Overturning orientation so that each need the workpiece that detects to be in identical placement state, convenient for the subsequent same position to workpiece into
Row detection, advantageously ensures that the objective and accurate property of testing result.
Further, workpiece turning directional operation is that the workpiece of machine-shaping is vertically fallen to reverses direction control hang plate
On, the tilt angle of reverses direction control hang plate makes the workpiece turning fallen on to unified placement state.Utilize work
The center of gravity of the differential seat angle and workpiece itself that contact between reverses direction control hang plate when part is fallen deflects, so that workpiece is fallen in
Reverses direction is overturn after controlling on hang plate to the state of steadily of centre of gravity, so that the upper and lower end face placement state one of multiple workpiece
It causes.
Further, the operation of workpiece automatic transportation is to be transported placement state workpiece adjusted using motor driven conveyer belt
It is defeated that workpiece is transported on monitor station on the outside of monitor station and by inclined feeding channel.It is brought into using motor-driven transmission
The transport of row workpiece, and workpiece is carried out to the feeding of monitor station using the gravity of workpiece itself, such the degree of automation is more
Height transports more efficient.
Further, it is that the first positioning installed on monitor station with feeding channel face is delayed that workpiece positions buffer operation for the first time
Block is rushed, the first buffer block that positions carries out the workpiece being slipped to from feeding channel on monitor station to stop positioning and buffering.
In this way to from feeding channel be slipped to the workpiece on monitor station carry out stop buffering avoid workpiece from going out monitor station, and
Initial position of the workpiece on monitor station is defined, is conducive to subsequent accurate travelling workpiece, to be detected.
Further, workpiece is oriented in workpiece dynamic testing method and mobile is utilized on monitor station that open up bar shaped logical
The pushing block of sliding is arranged in slot in bar shaped groove, and pushing block runs through monitor station, and the bottom end connection first of pushing block pulls cylinder, bar shaped
One end of through slot is located between feeding channel and first positioning buffer block, pulls cylinder to pull pushing block by workpiece edge by first
Bar shaped groove directional push.Bar shaped groove limits the motion track of pushing block in this way, and first pulls cylinder for pushing block
Power, can by workpiece from initial position along bar shaped groove displacement, realize real-time monitoring in the process of movement.
Further, it is in the process for being oriented promotion to workpiece that workpiece size detection is carried out in workpiece dynamic testing method
In from the side of workpiece moving direction origin reference location is carried out to workpiece, mechanical size comparison is carried out to workpiece from the other side, and
Size comparison result is converted to the optical signal of laser range sensor by light reflection.It is oriented in this way in workpiece
Side carries out the origin reference location of workpiece in moving process, and the other side can carry out the accurate detection of relative datum to the size of workpiece,
And the reflection of the change triggers light using workpiece size, so that the variation of size is converted to the reflection of light different angle, then
Signal collection is carried out by laser range sensor, accurate, automatically workpiece size can be detected.
Further, repositioning buffer operation is the displacement after carrying out workpiece size detection on monitor station in workpiece
Side sets up reposition buffer block and carries out stopping positioning and buffering to workpiece, and it is logical positioned at bar shaped to reposition buffer block
Outside of the slot far from first positioning buffer block one end.The workpiece after detection can be oriented using such method mobile
Final position limits, and avoids workpiece from going out monitor station, qualified workpiece is avoided to fall damage.
Further, direction vertical with bar shaped groove from monitor station after carrying out reposition buffer operation to workpiece pushes away
Part of starting building is discharged from monitor station.The avoidable workpiece discharge process of discharge workpiece determines next workpiece in this manner
It is impacted to moving process.
