Abstract
The invention discloses a cutting table mechanism for noncircular crystalline lenses. The cutting table mechanism comprises a crank and a rocker. The crank is capable of moving circumferentially around one end thereof, and the other end of the crank is connected with a slider. A linear guide rail is mounted on the bottom surface of the body of the rocker. The slider reciprocates linearly on the linear guide rail to drive the rocker to swing periodically. The cutting table mechanism is high in cutting efficiency and feeding speed, and products cut by the cutting table mechanism are high in stability and processing precision.
Description
Technical field
The present invention relates to a kind of non-circular lenticular cutting working platform mechanism that is applied to, belong to cutting working platform technical field.
Background technology
For lenticular cutting technique, adopting saw band to cut is a kind of method that precision is higher.As the cutting of the brilliant top of sapphire, be all generally to adopt saw band to cut.As shown in Fig. 1-1 and Fig. 1-2, first carry out circular lenticular cutting, workbench carries out turning circle Zhou Yundong by the driving of drive motors and reductor, thereby driven workpiece, is also to carry out circular motion.Described in Fig. 1-2, when saw band is carried out the lenticular cutting work of this circle, cutting effect is stable, and machining accuracy is better.As shown in Fig. 2-1 and Fig. 2-2, to carry out non-circular lenticular cutting, when non-circular crystalline lens is done revolution circular motion on workbench, each circumference cycle and saw band have two separation phases, and these two stages can not be carried out brilliant top cutting, so just there is the problem of secondary feed, and twice depth of cut is when carrying out numerical control programming, just there is the problem of feed difficulty, cutting efficiency is low, if enter excessive velocities, also there will be the phenomenon of gnawing cutter.
Summary of the invention
The invention provides a kind of non-circular lenticular cutting working platform mechanism that is applied to, solved the low problem of non-circular crystalline lens cutting technique precision, improve cutting efficiency, improve feed speed, improve machining accuracy.
The present invention realizes by following technical scheme:
Be applied to non-circular lenticular cutting and wave a table mechanism, comprise crank, described crank be take self a termination and is carried out circular motion as axle, and another termination of described crank connects a slide block; Also comprise rocking bar, a line slideway is installed in the body bottom surface of described rocking bar, and described slide block carries out linear reciprocating motion and makes described rocking bar do periodically oscillating motion on described line slideway.
It is that of connecting by described this head bottom part drives and reducing motor completes as axle carries out circular motion that described crank be take self termination.
A workbench is installed on the top of described rocking bar, and bottom is installed a bearing and made duplicate.
The invention also discloses a kind of employing cutting and wave the non-circular lenticular technique of table mechanism cutting, is to realize by following step:
(1) according to non-circular lenticular volume to be cut, calculate the most suitable saw band depth of cut, set the speed of waving and feed speed that workbench is waved in cutting;
(2) after above-mentioned parameter has been set, non-circular crystalline lens to be cut is put into cutting and wave workbench cutting, non-circular crystalline lens to be cut carries out oscillating motion on workbench, and saw band moves along cycloid in whole cutting process for non-circular lenticular cut point.
Feed speed in described step (1) is 3.5～5.5mm/min.
Beneficial effect of the present invention is:
1. for non-circular lenticular cutting, do not have secondary feed problem, the depth of cut is certain, and cutting is stable, and parameter is controlled.
2. machining accuracy is high, and original feed speed is increased to 3.5～5.5mm/min from 0.5mm/min, and efficiency promotes greatly.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Fig. 3-1 and 3-2, be respectively the present invention's cutting and wave front view and the top view of table mechanism, a kind ofly to be applied to non-circular lenticular cutting and to wave table mechanism, comprise crank 32, crank 32 be take self a termination and is carried out circular motion as axle, and another termination of crank 32 connects a slide block 31; Also comprise rocking bar 35, a line slideway 34 is installed in the body bottom surface of rocking bar 35, and slide block 31 carries out linear reciprocating motion and makes rocking bar 35 do periodically oscillating motion on line slideway 34.It is that of connecting by described this head bottom part drives and reducing motor 33 completes as axle carries out circular motion that crank be take self termination.A workbench 37 is installed on the top of rocking bar, and bottom is installed a bearing and made duplicate 36.
The present invention moves in a circle by crank, and slide block is done linear reciprocating motion, and rocking bar is done periodically oscillating motion and the non-circular crystalline lens workpiece 38 that completes is done periodically oscillating motion.This periodicity oscillating motion be according to the motion of rocking bar and wiggly, the circuit waving has cycloid.
Embodiment
Below with long 200mm, wide 50mm, height arbitrarily crystal is example as horizontal resection, traditional cutting mode as shown in the figure, Fig. 4-1 starts, workbench starts to enter the duty of circumgyration incision, Fig. 4-2, workbench is along with the direction of arrow, self rotates on one side, along the direction of arrow making progress, enter saw band cutting on one side, general setting feed speed is that 1mm/min advances, saw blade has just touched workpiece at this moment, cutting speed can only maintain 1mm/min, too high cutting speed can cause " gnawing cutter ", saw blade vibration, the phenomenons such as precise decreasing, from now starting timing, starting point as cutting process.Fig. 4-3, now feed speed still can only maintain 1mm/min, and the black shade in figure partly represents also not have the workpiece cross section of cutting, a not direct sum workpiece contact of saw band in a gyration period as can be seen from Figure, exist cut-in without ball phenomenon, wasted the time.Certainly topmost or feed speed does not increase.Fig. 4-4, accelerate, and at the uniform velocity traveling process above, measuring workpieces travel distance is 78mm, so the time of using is 78min, according to the size of workpiece, also need feed distance 25mm, so according to feed speed 4mm/min, need used time 6min.
As Fig. 4-5, be the cutting speed distribution map of traditional cutting mode, according to the statistics of above-mentioned data, show in the accompanying drawings, be 84min total clipping time.
Similarly, below with long 200mm, wide 50mm, height arbitrarily crystal is example as horizontal resection, adopts cutting mode of the present invention to cut.As Fig. 5-1, that workbench enters the schematic diagram that waves duty, as Fig. 5-2, workbench is along the direction of feed of vertical arrow, setting feed speed is 1mm/min, advance, according to the direction workbench that waves of horizontal arrow, wave simultaneously, due to employing, waving cutting is can not produce cut-in without ball phenomenon, after the 3mm left and right of having advanced, just can carry out high-speed cutting, as Fig. 5-3, after the feed speed that adopts before 1mm/min has been advanced 3mm, namely used 3min, start afterwards to enter high-speed cutting state, adjustment feed speed is 4mm/min, if the 3mm advancing ignores before, as Fig. 5-4, travel distance is still 200mm, traveling time is 53min so.
As Fig. 5-5, it is the cutting speed distribution map of cutting mode of the present invention.
From above-mentioned data, can find out, the present invention is than traditional circumgyration incision mode, and the ratio of clipping time is 84:53, i.e. 1.585:1.Greatly improved operating efficiency, the operating accuracy simultaneously also improving.
