Axis vertical centre point is P points, using central shaft is the rotation of axis clockwise, width of the workpiece L1, Workpiece length L2, workpiece circular arc when work
Radius R1 and polishing wheel radius R2 is known design parameter, and polishing wheel moves up and down in OP lines direction when operation, moves
Distance is related with the rotational angle of workpiece, and after being calculated by program, the displacement distance of polishing wheel is accurately adjusted with servo motor,
It is required to reach control, particular content is：
When workpiece turns to long edge polishing angle, set polishing wheel and workpiece point of contact the edge of work movement speed
V while starting operation, starts timer and finds out angle from A points to distance AB=VT, tang α=AB/ (R2+L1/2) of B points
While degree α can be obtained by the real-time angular speed of workpiece later, the distance OP=(R2+ of polishing wheel midpoint P to workpiece midpoint O
L1/2)/cos α, to show that polishing wheel needs the distance risen in real time；
When rotational angle has arrived point of contact and is in arc chord angle, calculation formula has change, arc length BC=VT, β=(arc length BC/2 π
R1) * 360, PQ=R1+R2, in right angled triangle PQE, cos β=QE/PQ, therefore QE length can be calculated, in right angle trigonometry
In shape ODQ, OD=L1/2-R1, QD=L2/2-R1=EF, OF=OD+DF=OD+QE, PE=PQ*sin β, PF=PE+QD,
In right angled triangle POF, tang α=PF/OF, after finding out angle [alpha], OP=PF/sin α thus obtain OP length, pass through
Servo motor is accurately positioned.
Compared with prior art, the present invention has the following advantages：
1. the surrounding applied in the surrounding multilist mirror polish of the center of suitable consumer electronics mobile phone hardware, dorsal shield
Multi-panel polishes.
2. polishing wheel leans on clamping of workpieces to run always in the process of running, the relative motion of itself and workpiece is made to be in suitable pressure
The point of contact of power state, polishing wheel and workpiece is at the uniform velocity moved in workpiece surrounding, to reach best polishing efficiency and effect.
3. grinding fluid when polishing is sprayed from top to bottom, horizontal positioned workpiece can make grinding fluid uniformly be sprayed on machined surface, improve
Polishing efficiency and quality.
Description of the drawings
Fig. 1 workpiece are in horizontal position schematic diagram；
Fig. 2 workpiece are in mill long side position；
Fig. 3 workpiece are in mill arc position.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and embodiments.
