Background technology
For existing glossing, due to also there is mechanical hand or artificial monolithic sanding and polishing, single face sanding and polishing Efficiency, yields are relatively low, the problems such as equipment cost, cost of labor are higher, thus can not preferably be applied to consumer electronicses handss The center of machine hardware, the surrounding multilist mirror polish of shell on the back, also cannot be applied to 2.5D glass, sapphire and other Firmly, the surrounding multilist mirror polish of crisp material.
Content of the invention
The technical problem to be solved is to beat for existing manipulator or artificial monolithic sanding and polishing, single face Grinding and polishing light efficiency, yields are relatively low, the higher problem of equipment cost, cost of labor, provide a kind of multi-surface glossing.
The technical solution adopted for the present invention to solve the technical problems is:A kind of multi-surface glossing, will polish Workpiece fold in the same direction neat after, with cylinder clamping in machining position, machined surface horizontal positioned, workpiece rotary shaft in the horizontal plane, with throwing Halo central shaft is parallel, and is in immediately below it, opens grinding fluid pump, so that grinding fluid is ejected on machined surface, by cyclelog Calculate the running orbit of buff wheel, buff wheel while rotation, at the uniform velocity move in workpiece surrounding by the point of contact of buff wheel and workpiece, The interaction of buff wheel and grinding fluid makes the surrounding of workpiece be polished, and the folded workpiece of polishing one only needs to shutdown and lays once, Polishing efficiency greatly improves.
Further, the computational methods of the running orbit of described buff wheel are:
The central axis central point of workpiece is O point, is rotated with central shaft for axle clockwise, the center of buff wheel during work Axle vertical centre point is P point, is rotated with central shaft for axle clockwise, width of the workpiece L1, Workpiece length L2, workpiece circular arc during work Radius R1 and buff wheel radius R2 is known design parameter, and during operation, buff wheel moves up and down in OP line direction, its movement Distance is relevant with the rotational angle of workpiece, after calculating, accurately adjusts the displacement of buff wheel by program with servomotor, Thus reach control requiring, particular content is:
When workpiece turns to long edge polishing angle, set the buff wheel and workpiece point of contact translational speed in the edge of work V, while startup optimization, starts timer, from A point to B point apart from AB=VT, tang α=AB/ (R2+L1/2), obtains angle Degree α after can be obtained by workpiece real-time angular velocity while, buff wheel midpoint P is to workpiece midpoint O apart from OP=(R2+ L1/2)/cos α, thus just can show that buff wheel needs the distance rising in real time;
When rotational angle has arrived point of contact and is in arc chord angle, computing 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 obtaining angle [alpha], OP=PF/sin α, thus draw OP length, pass through Servomotor is accurately positioned.
Compared with prior art, the present invention has advantages below:
1. be suitable for the center of consumer electronicses mobile phone hardware, in the surrounding multilist mirror polish of shell on the back application surrounding Many mirror polish.
2. buff wheel is close to workpiece in running all the time and runs so as to be in suitable pressure with the relative motion of workpiece The point of contact of power state, buff wheel and workpiece is at the uniform velocity moved in workpiece surrounding, to reach optimal polishing efficiency and effect.
3. grinding fluid when polishing is sprayed from top to bottom, and horizontal positioned workpiece can make grinding fluid uniformly be sprayed on machined surface, improves Polishing efficiency and quality.
Brief description
Fig. 1 workpiece is in horizontal level schematic diagram;
Fig. 2 workpiece is in mill long side position;
Fig. 3 workpiece is in mill arc position.
Specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment
A kind of multi-surface glossing, after the workpiece that will polish is folded neatly in the same direction, with cylinder clamping in machining position, processes Face horizontal positioned, workpiece rotary shaft is in the horizontal plane, parallel with buff wheel central shaft, and is in immediately below it, opens grinding fluid pump, So that grinding fluid is ejected on machined surface, calculate the running orbit of buff wheel by cyclelog, buff wheel, while rotation, is thrown The point of contact of halo and workpiece is at the uniform velocity moved in workpiece surrounding, and the interaction of buff wheel and grinding fluid makes the surrounding of workpiece be thrown Light, the folded workpiece of polishing one only needs to shutdown and lays once, and polishing efficiency greatly improves.
The computational methods of the running orbit of described buff wheel are:
With reference to Fig. 1, the central axis central point of workpiece is O point, is rotated with central shaft for axle clockwise during work, polishing The central axis central point of wheel is P point, is rotated with central shaft for axle clockwise, in figure, width of the workpiece L1, workpiece are long during work Degree L2, Workpiece's Arc Radius R1 and buff wheel radius R2 are known design parameters, and during operation, buff wheel is on OP line direction Lower movement, its displacement is relevant with the rotational angle of workpiece, after calculating by program, accurately adjusts polishing with servomotor The displacement of wheel, thus reach control require.
As shown in Fig. 2 when workpiece turns to long edge polishing angle, setting buff wheel and workpiece point of contact in the edge of work Translational speed V, while startup optimization, start timer, from A point to B point apart from AB=VT, tang α=AB/ (R2+ L1/2), can be obtained by after obtaining angle [alpha] workpiece real-time angular velocity while, buff wheel midpoint P is to workpiece midpoint O's Apart from OP=(R2+L1/2)/cos α, thus just can show that buff wheel needs the distance rising in real time.
