Detailed Description

The following detailed description will be made with reference to the accompanying drawings and examples, so that how to implement the technical means of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Referring to fig. 1, fig. 1 is a schematic view of a lens ring groove polishing device according to an embodiment of the present invention.

As shown in the drawings, a lens ring groove grinding device comprises: the device comprises a machine frame 10, wherein the machine frame 10 is provided with a working table top 11; grinding machanism 20 of setting in table surface 11 one side, grinding machanism 20 includes: the polishing machine comprises a movable bottom plate 21 connected to the working table 11 in a sliding mode, a sliding block 22 connected to the movable bottom plate 21 in a sliding mode, a polishing support 23 and a polishing motor 24 fixed to the sliding block 22, a rotating shaft 25 driven by the polishing motor 24 and a polishing head 26 arranged at the end portion of the rotating shaft 25, wherein a limiting plate 211 is arranged on one side of the sliding block 22 on the movable bottom plate 21, and a plurality of groups of springs 30 are arranged between the limiting plate 211 and the sliding block 22; the positioning mechanism 40 is arranged on the other side of the working table 11, the positioning mechanism 40 comprises a positioning support 41, a positioning column 42 rotatably connected to the positioning support 41 and a positioning motor 43 driving the positioning column 42 to rotate, a positioning seat 50 is arranged at the upper end of the positioning column 42, a lens groove 51 for placing a lens is formed in the positioning seat 50, and a vacuum suction cup 52 is arranged in the lens groove 51.

In one embodiment of the present invention, the frame 10 is provided with a brace 60 for supporting the entire frame. The frame 10 is provided with a worktop 11.

Table surface 11 one side is equipped with grinding machanism 20, and grinding machanism 20 includes: a movable base plate 21 slidably attached to the table top 11, a slide 22 slidably attached to the movable base plate 21, a grinding bracket 23 and a grinding motor 24 fixed to the slide 22, a rotary shaft 25 driven by the grinding motor 24, and a grinding head 26 provided at an end of the rotary shaft 25. Wherein, a handle 70 is arranged on one side of the movable bottom plate 21 to facilitate pushing the movable bottom plate 21. A limiting plate 211 is arranged on one side of the sliding block 22 on the movable bottom plate 21, and a plurality of groups of springs 30 are arranged between the limiting plate 211 and the sliding block 22. Preferably, there are 3 sets of springs 30.

Furthermore, a positioning mechanism 40 is disposed on the other side of the working platform 11, and the positioning mechanism 40 includes a positioning bracket 41, a positioning column 42 rotatably connected to the positioning bracket 41, and a positioning motor 43 for driving the positioning column 42 to rotate. Wherein, the upper end of the positioning column 42 is provided with a positioning seat 50, the positioning seat 50 is provided with a lens groove 51 for placing a lens, a vacuum chuck 52 is arranged in the lens groove 51, and the vacuum chuck 52 is connected with a vacuum generator.

When the annular groove of the side wall of the lens needs to be polished, the lens is placed on the lens groove 51, and then the vacuum chuck 52 adsorbs the lens, so that the lens can be positioned. The moving base plate 21 is then pushed so that the sanding head 26 stops in the annular groove in the lens sidewall. The grinding motor 24 and the positioning motor 43 are turned on and the lens and the grinding head 26 are both rotated so that the ring groove of the lens can be ground. Because the plurality of sets of springs 30 are arranged between the limit plate 211 and the slider 22, when the moving base 21 does not move, the sanding head 26 can still stretch and contract under the elastic action of the springs 30. The annular groove of the side wall of the lens is irregular and annular, the polishing head 26 which can freely stretch and retract can be in contact with the annular groove of the lens more fully, the polishing effect on the annular groove is good, the position of the polishing head does not need to be adjusted, and the use is convenient.
