Technical Field
The invention belongs to the field of optical cold machining, and particularly relates to a device for polishing a conical lens.
Background
The optical conical lens is an aspheric lens processed by optical glass, can effectively reduce spherical aberration and chromatic aberration, and has a light-transmitting conical surface with surface quality close to that of a standard conical surface; therefore, a high-precision numerical control polishing machine tool is generally needed for polishing, and the problems of expensive processing equipment, complex structure and long processing time exist, so that a device for polishing the conical lens is needed to realize low-cost and high-efficiency processing, and further realize the polishing processing of the conical lens in large batch.
Disclosure of Invention
The invention aims to provide a device for polishing conical lenses, which can realize low-cost and high-efficiency processing, thereby realizing the polishing processing of the conical lenses in large batch.
The invention adopts the following technical scheme to solve the technical problems.
The head and the tail of the two distance-adjusting bolts are respectively hinged with the swing rod and the angle-adjusting rod, so that the length of the distance-adjusting bolts is adjusted to adjust the conical generatrix of the conical lens to be in parallel contact with the surface of the circular polishing disc to polish the conical surface; the circular polishing disc surface rotates at a high speed along a main shaft of the polishing disc surface, the conical lens is fixedly connected with a main shaft rod through glue, the main shaft rod is coaxially connected with the angle adjusting rod through a bearing, so that the conical lens and the main shaft rod can freely rotate along the axis of the angle adjusting rod, and the swing rod can reciprocally swing around a swing rod shaft, so that the angle adjusting rod, the main shaft rod and the conical lens are driven to reciprocally swing around the swing rod shaft; compared with a numerical control polishing machine, the device has a relatively simple structure and low manufacturing cost, and can realize the complete contact of a conical generatrix of the conical lens surface and the polishing disc, the conical lens passively rotates along the axis of the angle adjusting rod under the drive of the high-speed rotation of the circular polishing disc surface, and the conical lens can ensure that the polishing removal efficiency of each area of each conical surface is adjustable under the drive of the swing rod shaft, so that the high-speed polishing processing is realized, and the polishing processing of a large batch of conical lenses can be realized.
