[0025] At least one of the upper pinch roller 1211 and the lower pinch roller 1221 is connected with a spindle lifting component, which is used to drive the upper pinch roller 1211 and / or the lower pinch roller 1221 to lift, so that the upper pinch roller 1211 and the lower pinch roller 1221 can be relatively opened and tightly fixed. When the upper pinch roller 1211 and the lower pinch roller 1221 are relatively opened, it is convenient to place the lens on the lower pinch roller 1221; when the upper pinch roller 1211 and the lower pinch roller 1221 are relatively tightly fixed, the lens is fixed between the upper pinch roller 1211 and the lower pinch roller 1221. In the present application, the upper pinch roller 1211 is connected with the spindle lifting component (not shown in the spindle lifting component), and the spindle lifting component is a lifting motor or the like. Figure 1 、 Figure 2 The spindle lifting component is not shown in the spindle lifting component).

[0026] At least one of the upper pinch roller 1211 and the lower pinch roller 1221 is connected with a spindle rotating component, which is used to drive the upper pinch roller 1211 and / or the lower pinch roller 1221 to rotate, so that the upper pinch roller 1211 and / or the lower pinch roller 1221 can drive the lens to rotate after tightly fixing the lens.

[0028] The rough-milling mechanism 15 comprises a milling cutter 151, a milling cutter rotating driving component 152 and a milling cutter feeding and retracting driving component 153, and is used for performing preliminary turning processing on the lens blank to remove most of the excess material and lay a foundation for subsequent finishing of the lens.

[0029] The working principle of the lens rough-milling and edging machine 100 is as follows: first, the lens is placed on the lower pressing wheel 1221, and then the lens is positioned by the positioning mechanism 14, and then the upper pressing wheel 1211 and the lower pressing wheel 1221 of the fixing mechanism 12 press and fix the lens; the fixing mechanism 12 drives the lens to rotate, and the rough-milling mechanism 15 performs rough-milling and edging work on the lens, and after the rough-milling and edging is completed, the rough-milling mechanism 15 is reset.

[0030] Through the above arrangement, the present application only needs to rough-mill the lens blank once, and then finish the rough-milled lens once, so that the lens finished product can be obtained. Therefore, compared with the traditional lens edging processing method which needs to be edged for multiple times, the present application improves the working efficiency of lens edging.

[0031] As an implementation manner, the rough-milling mechanism 15 further comprises a mounting plate 154, a lifting plate 18 and a lifting mechanism 19.

The lifting screw rod 191 is rotated to drive the lifting screw nut to move up and down along the length direction of the lifting screw rod 191, thereby driving the lifting plate 18 to move up and down. Different milling cutters 151 are replaced according to the thickness or the curvature of different lenses, and the height of the milling cutter 151 is adjusted by controlling the lifting of the lifting plate 18 through the lifting mechanism 19, so that the rough milling mechanism 15 can adapt to the rough milling of lenses with different thicknesses.

[0034] Specifically, the lifting screw rod 191 is fixedly connected with a lifting hand wheel 193, and the lifting hand wheel 193 is manually rotated to drive the lifting screw rod 191 to rotate, so that the height of the lifting plate 18 is manually adjusted to save labor.

The connecting rod 1572 and the guide seat 181 are in sliding connection in the front and back directions, and the connecting rod 1572 is fixedly connected with the mounting plate 154. Specifically, the connecting rod 1572 is fixedly connected with a second connecting plate 1573, the second connecting plate 1573 is fixedly connected with the mounting plate 154, and the first connecting plate 1571 and the second connecting plate 1573 are arranged at the two ends of the connecting rod 1572 and perpendicular to the connecting rod 1572.

[0037] The first connecting plate 1571 is provided with a connecting rod mounting hole for clamping and matching with the connecting rod 1572. The first connecting plate 1571 is provided with an adjusting screw 158. The adjusting screw 158 is threadedly connected with an adjusting nut 159.

[0038] As an implementation manner, the lifting plate 18 is provided with two groups of rough milling mechanisms 15. Through the above arrangement, the workstations of the lens rough milling machine are increased, so as to improve the work efficiency of the lens rough milling machine. Only one lifting mechanism 19 is needed to simultaneously lift two groups of rough milling mechanisms 15, so that the structure of the lens rough milling machine 100 is more compact and the cost of the lens rough milling machine 100 is reduced.

After the two positioning clamping jaws 141 are clamped, the arc-shaped positioning surface 1411a of the positioning clamping arm 1411 is matched with the lower spindle 122, which plays a limiting role on one hand to prevent the positioning clamping jaw 141 from being clamped too tightly to cause damage to the lens, and plays a center positioning role on the other hand to make the central axis of the two positioning clamping jaws 141 coincide with the axis of the lower spindle 122; in addition, the four positioning columns 1412 of the two positioning clamping jaws 141 abut against the outer peripheral edge of the lens to make the center of the lens coincide with the axis of the spindle.
