The invention is provided with a vertical basic plate which is connected with a grinding mechanism which can be adjusted in an inclined angle by the vertical basic plate and can be driven to swing by a driving mechanism, and a displacement mechanism which is provided with a sliding block which can longitudinally move and can be used for supporting the vertical basic plate; by adopting the structure, the grinding device can correct the amplitude of swing and the central point of the swing amplitude according to the spherical center and the diameter of the arc of the processed eyeglass correspondingly before the grinding operation is carried out, so as to position the best grinding position.
Description
Technical field
The present invention relates to a kind of lens grinding device that can directly adjust according to lens centre and arc, particularly a kind of lens grinding device can adjust the vertical displacement of grinding mechanism simultaneously and incline, the elevation angle, with the amplitude of oscillation and the amplitude of oscillation central point of directly proofreading and correct grinding mechanism according to the centre of sphere and the arc of machining lens.
Background technology
As shown in Figure 7, be lens grinding device commonly used, it has workbench 90, having a rotating shaft 91 on this workbench 90 is installed in corresponding bearing block that is provided with 92 and the locating rack 93, and extension bar 94 is hubbed at the front end of this rotating shaft 91, and this extension bar 94 has thimble 941, and pneumatic cylinder 95 two ends are hubbed at respectively in this extension bar 94 and this rotating shaft 91, and be connected in crank 96 in the other end of this rotating shaft 91, and drive these cranks 96 by drive unit 97, make these rotating shaft 91 left-right rotation and drive extension bar 94 and swing thereupon.
During general grind spectacle lens, seeing through this pneumatic shuttle 95 makes this thimble 941 force in mill ware 98, to grind the eyeglass 99 of desire processing on grinding table, and eyeglass 99 arcs that the central point that must directly proofread and correct the amplitude of oscillation that this mill ware 98 swings and the amplitude of oscillation according to eyeglass 99 desired grinding arcs before grinding and desire are ground are directly identical with the centre of sphere, to reach the grinding effect of the best.When eyeglass grinder of using always such as desire are changed the eyeglass grinding in different arcs footpath, must adjust the eyeglass height with tool usually and make the thimble of the center cooperation eyeglass grinder in eyeglass arc footpath force in the swinging arc center of grinding ware and swinging.Therefore, when grinding the eyeglass in different arcs footpath, then must change the tool of differing heights and increase production cost, and as during the precision deficiency of tool height, its adjustment then seems difficult.
In addition, the mill ware is behind grind spectacle lens, and its abradant surface can form abrasion to a certain degree, causes grinding the centre of sphere and is offset with the wear intensity that grinds ware, and then cause the deviation of the eyeglass precision of grinding.And eyeglass grinder commonly used can't directly be adjusted centre of sphere distance, makes the mill ware when abrasion produce, and is difficult to proofread and correct the centre of sphere distance between itself and eyeglass, and how therefore often essential finishing mill ware address the above problem and then be emphasis of the present invention place.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Shown in Fig. 1 to 4, present embodiment provides a kind of lens grinding device that can directly adjust according to lens centre and arc, and it comprises:
Displacement mechanism 4, it comprises:
By said structure as can be known, when desiring grind spectacle lens 6, motor 31 by this driving mechanism 3 drives offset assembly 32, make this offset assembly 32 drive crank 23 and drive the just reverse pivot of this rotating shaft 21, and then the extension bar 22 of these grinding mechanism 2 other ends of interlock swings in a radian scope, makes the thimble 221 on this extension bar 22 drive the swing that mill wares 5 are a radian.The amplitude of fluctuation size of this extension bar 22 is by the angle control of 21 of this extension bar 22 and this rotating shafts, and then amplitude of fluctuation is littler when angle is healed when big, otherwise then amplitude of fluctuation is bigger.And the angle of 21 of this extension bar 22 and this rotating shafts is adjusted the inclination angle of these vertical substrates 1 by this second rotating unit 34, make this grinding mechanism 2 tilt to the angle that needs with this vertical substrate 1, be connected in fixed position in this rotating shaft 21 by adjusting this pneumatic cylinder 24 again, this extension bar 22 is resetted in abrasion site.
Above-mentioned action is roughly identical with eyeglass grinder running commonly used, but difference of the present invention be in, because this grinding mechanism 2 is arranged at vertical substrate 1, can adjust this slide block 41 along these guide pillar 424 longitudinal axis upper and lower displacements by turning handwheel 431 first drive screws 43, and make grinding mechanism 2 be the displacement of vertical direction with vertical substrate 1.Therefore, when the angle of 22 of the rotating shaft 21 of grinding mechanism 2 and this extension bars is adjusted to (referring to Fig. 5) when meeting the eyeglass arc footpath that desire grinds, can adjust this slide block 41 by this first rotating unit 33 upwards or down moves (referring to Fig. 6, it is for being adjusted to abrasion site downwards by Fig. 5 position), make the amplitude of oscillation of the thimble 221 of this extension bar 22 be centrally located in the lens centre that desire is ground, to reach best grinding effect.
