Description

Technical Field

[0001] The utility model relates to the technical field of optical lens manufacturing, in particular to a fixture for edge grinding of glass lenses. Background Art

[0002] At present, the edge grinding of soft material glass lenses on the market after molding and hot forming is very prone to clamp damage and eccentricity. Specifically, when clamping the lens, due to the strong clamping force, clamp damage is easy to occur during the edging process, and if the clamping force is weak, it is easy to be eccentric. Utility Model Content

[0003] Purpose of the utility model: In order to solve the above technical problems, the utility model provides a fixture for grinding the edge of a glass lens.

[0004] Technical solution: The utility model is a fixture for edge grinding of glass lenses, comprising a main body, on which a contact head is arranged, wherein both the interior of the contact head and the interior of the main body are provided with through holes, and the contact head and the through holes in the main body are connected; the contact head is made of bakelite.

[0005] Furthermore, a connection hole is provided in the main body, and the contact head has a connection end inserted into the connection hole.

[0006] Furthermore, the connecting end is embedded in the connecting hole.

[0007] Furthermore, the end of the contact head has a recess.

[0008] Furthermore, the main body is made of copper.

[0009] Beneficial effects: The glass lens edge grinding fixture of the utility model has the following beneficial effects:

[0010] The utility model can prevent the clamp from causing damage when clamping the lens by arranging a contact head made of bakelite at the end of the clamp body, thereby effectively solving the problems existing in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the utility model.

[0013] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0014] like Figure 1As shown, a fixture for edge grinding of glass lenses of the utility model comprises a main body 1 made of copper, a contact head 2 is arranged on the main body 1, the contact head 2 and the main body 1 both have through holes, and the contact head 2 is connected to the through holes in the main body 1, and the contact head 2 is made of bakelite. A connecting hole 11 is arranged in the main body 1, and the contact head 2 has a connecting end 12 inserted into the connecting hole 11. Specifically, the connecting end 12 is embedded in the connecting hole 11, and the connecting end 12 is softened by a traditional high-temperature softening process to connect the bakelite into the connecting hole 11, and the embedding is completed after cooling, and the embedded structure is strong and durable. The end of the contact head 2 has a recess 22, and the recess 22 forms an air nozzle.

[0015] When in use, two clamps of the utility model are fixed on the main shaft of the core extractor, and the hole at the end of the main body 1 is connected to the external suction device; the lens is clamped between the two clamps, and the contact head 2 is used to contact the surface of the lens. When the external suction device is started, a negative pressure is formed at the recess 22, which can make the contact head adsorb on the surface of the lens and increase the contact force. Then the main shaft of the core extractor is started to rotate at high speed, driving the clamp and the lens to rotate at high speed, and the grinding wheel slowly contacts the lens to grind the edge. When the outer diameter of the lens reaches the target value, the core extraction work is completed. The contact head 2 made of bakelite can effectively prevent the damage that may occur to the lens during the edge grinding process based on its material properties.

[0016] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementation modes. For those skilled in the art, any technical solutions formed by any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
