Description

Technical Field

[0001] The present invention relates to the field of glass lens processing, and particularly to a processing device for high-precision plane mirrors. Background Art

[0002] Currently, due to the different hardness (abrasion degree) of the marble pressing plate of the original ring polishing equipment and the product material in the processing of plane lenses, two different material grinding debris powders are mixed in the grinding fluid, interfering with each other, resulting in the surface quality of the product not being guaranteed. Summary of the Invention

[0003] To solve the above problems, the present invention discloses a processing device for high-precision plane mirrors, with a reasonable structural design, increasing the trajectory area of the grinding of plane mirror lenses and ensuring the surface quality of the lenses.

[0004] A processing device for high-precision plane mirrors includes a ring polishing table and a rotating mechanism arranged at the bottom of the ring polishing table; several marble workpiece rings are arranged on the ring polishing table; a limit rotation assembly is arranged beside the ring polishing table; the limit rotation assembly includes a support frame, limit arms fixed on both sides of the support frame, auxiliary wheels, a motor and a driving wheel, a hydraulic device and a driven wheel; the motor is fixed on the support frame and the bottom is connected to the driving wheel, and the driving wheel is rotationally and fittingly matched with the side of the marble workpiece ring; the limit arms are located beside the marble workpiece ring and the ends are connected to the auxiliary wheels fittingly matched with the side surface of the marble workpiece ring, and three positioning grooves are uniformly arranged on the top end surface of the marble workpiece ring; a first threaded hole is arranged in each positioning groove; a top cover is arranged on the top of the marble workpiece ring; the extending part of the top cover is clamped and fixed in the corresponding positioning groove and locked in the first bolt hole with a bolt, and an eccentric hole is arranged on the top cover.

[0005] Further, the included angle between the center lines of every two adjacent positioning grooves is 120°.

[0006] Further, a special lining plate is arranged at the bottom of the marble workpiece ring, and the material of the special lining plate is the same as that of the glass lens to be processed and is detachable. A plurality of second threaded holes are arranged on the surface of the marble workpiece ring; a special lining piece is arranged at the bottom of the marble workpiece ring; the material of the special lining piece is the same as that of the glass lens to be processed and is detachable, and can be replaced according to the product to be processed, avoiding the mixing of two different material grinding debris powders in the grinding fluid due to the different hardness (abrasion degree) of the marble pressing plate and the product material, interfering with each other, and damaging the surface of the lens to be processed.

[0007] Further, there is a gap between the bottom of the marble workpiece ring and the special lining piece, facilitating the timely discharge of waste chips and lubricating fluid generated during the ring polishing process;

[0008] Furthermore, the top cover is made of plexiglass.

[0009] Furthermore, the diameter of the eccentric hole is adjusted according to the size of the product to be processed.

[0010] The working principle of the present invention is as follows:

[0011] 1. Place the plane mirror workpiece to be processed into the eccentric hole; the rotating mechanism drives the ring polishing table to move. At the same time, the motor drives the driving wheel to rotate, and the driving wheel drives the marble workpiece ring to rotate. Due to the provision of the limiting arm, the limiting and auxiliary rotation is realized through the driven wheel on the limiting arm. In addition, a hydraulic device is provided, and through the hydraulic device, the driven wheel realizes smooth rotation;

[0012] 2. Since the original workpiece only rotates at a fixed position on the marble polishing ring, the grinding contact area between the plane mirror lens and the ring polishing table is limited. Rotating in the eccentric hole can change the single movement trajectory of the original workpiece, enabling the workpiece to expand its movement range on the grinding disc and making it possible to obtain a high-precision surface shape;

[0013] 3. A special lining plate is provided at the bottom of the marble workpiece ring and is locked and fixed by the second bolt, which is convenient for installation and disassembly. Among them, the special lining plate is replaced according to the different materials of the grinding lens to ensure that the lens has good surface quality;

[0014] 4. There is a gap between the marble workpiece ring and the special lining plate, which can allow more polishing liquid to enter, increasing the polishing efficiency, and the grinding debris generated by the marble and the glass can also be better discharged.

[0015] The beneficial effects of the present invention: The structure is reasonably designed, increasing the trajectory area of the plane mirror lens grinding. At the same time, the movement trajectory of the workpiece ring is relatively limited, enabling the product processing process to proceed smoothly, preventing breakage during the product processing process, and effectively improving the surface quality and processing efficiency of the lens.
