Description

Technical Field

[0001] The utility model relates to a rough and fine grinding device for a lens, belonging to the technical field of lenses. Background Art

[0002] Lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. After polishing, they are often assembled with glasses frames to form glasses. They are used to correct the user's vision and obtain a clear field of vision. Lenses also include projector lenses. The rough blank can be used after polishing.

[0003] Fine grinding equipment is required for the rough grinding of projector lenses, but the existing fine grinding equipment does not have the function of collecting waste chips. Often when fine grinding the rough lens, a large amount of waste chips may be generated due to the high-speed rotation of the grinding head. The waste chips may splash onto the surface of the lens, causing it to wear, affecting the fine grinding quality and reducing work efficiency.

[0004] Therefore, a rough and fine grinding device for lens is proposed. Utility Model Content

A gantry 17 is fixedly connected to the top of the fine grinding table 1, a support plate 15 is welded to the top of the gantry 17, an electric slide seat 14 is arranged on the top of the support plate 15, electric sliders 12 are slidably connected to the front and rear sides of the bottom of the electric slider 14, a vertical rod 11 is welded to the bottom of the electric slider 12, a connecting plate 8 is welded to the bottom of the vertical rod 11, and a feed trough 3 is opened on the front and rear sides of the top of the fine grinding table 1. A chip suction assembly 4 is provided at the middle end of the bottom of the fine grinding table 1, and the chip suction assembly 4 includes a chip suction box 401, a material dropping chute 402, a filter 403, a holder 404 and a fan 405. Support legs 18 are welded on both sides of the bottom of the fine grinding table 1. The chip suction box 401 is fixedly connected to the middle end of the bottom of the fine grinding table 1, the material dropping chute 402 is opened at the top of the chip suction box 401, the holder 404 is welded to the left and right sides of the inner cavity of the chip suction box 401, the filter 403 is clamped on the inner side of the holder 404, and the fan 405 is arranged at the bottom of the chip suction box 401.

[0026] The scraper 6 can be driven to move inward through the action of the electric slide 14 and the electric slider 12, so that the waste chips generated during the fine grinding process can be scraped into the feed trough 3, and then fall into the inner cavity of the chip suction box 401 through the feed trough 3 and the drop trough 402. The fan 405 can generate downward suction, making it easier for the waste chips to enter the chip suction box 401. The waste chips finally fall to the top of the filter 403 for isolation, making it convenient for the staff to clean up. Through the above cooperation, the function of collecting waste chips is achieved, avoiding excessive waste chips during the fine grinding of the lens, thereby avoiding the wear of the lens surface, improving the processing quality and ensuring the cleanliness of the top of the fine grinding table 1.

[0027] Example 2

[0028] In one embodiment, the mounting seat 7 is welded to the bottom of the connecting plate 8, the scraper 6 is clamped in the mounting seat 7, an inspection door 5 is provided on the front side of the chip suction box 401, and the inner surface of the inspection door 5 is threadedly connected to the chip suction box 401 by fastening screws on all sides, a cylinder 13 is fixedly connected to the middle end of the top of the gantry 17, a fixed frame 16 is provided at the bottom of the cylinder 13, a rotating motor 10 is provided on the inner side of the fixed frame 16, and a fine grinding head 9 is fixedly connected to the output end of the rotating motor 10, and chip guard plates 2 are welded on the left and right sides of the top of the fine grinding table 1, and the chip guard plates 2 are triangular.

[0029] By setting the mounting seat 7, it is convenient for the staff to disassemble the scraper 6, which is convenient for cleaning or replacement at a later time. By setting the inspection door 5, it is convenient for the staff to take out the filter 403 for replacement, which is convenient for maintenance. By setting the chip guard plate 2, the two sides of the fine grinding position can be blocked to prevent waste chips from splashing.

[0030] When the utility model is working: first, the projector lens that needs to be fine-ground is placed on the middle end of the top of the fine-grinding table 1, and the fine-grinding head 9 is driven to rotate by the output end of the rotating motor 10, and the fine-grinding head 9 is driven downward by the extension of the cylinder 13 to fine-grind it. During the fine-grinding process, a large amount of waste chips will be generated. At this time, the scraper 6 can be driven to move inward through the action of the electric slide 14 and the electric slider 12, and the waste chips generated during the fine-grinding process are scraped into the feed trough 3, and fall into the inner cavity of the chip suction box 401 through the feed trough 3 and the drop trough 402. The setting of the fan 405 can generate downward suction, so that the waste chips can enter the chip suction box 401 more easily, and the waste chips finally fall to the top of the filter screen 403 for isolation, which is convenient for the staff to clean. Through the above-mentioned cooperation, the function of collecting waste chips is realized, and excessive waste chips are avoided in the process of fine-grinding the lens, which then causes the lens surface to wear, improves the processing quality and ensures the cleanliness of the top of the fine-grinding table 1.
