Description

Technical Field

[0001] The present application relates to the technical field of lens grinding, and in particular to a high-precision smooth edge grinding machine. Background Art

[0002] Optical lenses mainly refer to lenses made of optical glass. Optical glass refers to glass that can change the direction of light propagation and the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass can be used to manufacture lenses, prisms, reflectors, etc. in optical instruments. Qualified optical glass is heated and forged to become optical lens blanks. The optical lens blanks need to be edged, and special edge grinding equipment is usually used to edge the optical lenses.

[0003] As disclosed in Chinese Patent Publication No. (CN218856447U), an optical lens edging device includes a device body, an upper surface of which is provided with a lifting rod, and an upper end of the lifting rod is provided with a handle. In this utility model, the optical lens is placed between two suction cups, and the suction cups move toward the middle under the action of a damping spring to fix and clamp the optical lens. Then, the bidirectional screw rod is rotated by the handle to make the two moving rods move relative to each other, and then the distance between the two grinders is adjusted according to the specifications of the optical lens, and the inclination angle of the grinder is adjusted at the same time. Finally, the lifting rod is pulled downward by the handle to make the grinding wheel of the grinder contact with the optical lens, and the optical lens is polished. This utility model has a simple structure and is easy to operate. It can perform polishing operations on optical lenses of different specifications, so that the edge surface of the optical lens has an arc-shaped structure, improves its smoothness, and greatly improves the practicality of the device.

[0004] However, the prior art, such as the above-mentioned patent, still has the problem of poor edge grinding and smoothing effect on optical lenses. In the prior art, the optical lens is ground by contacting the grinding wheel of the grinder with the optical lens. The grinding wheel in the prior art adopts a diamond grinding disc, which is composed of a plurality of diamond grains. It is easy to wear unevenly during use, resulting in the polished surface not being smooth enough, affecting the optical performance of the optical lens. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a high-precision smooth edge grinding machine with advantages such as good polishing effect, which solves the problem of poor polishing effect on the edges of optical lenses.

[0006] To achieve the above-mentioned object, the present application provides the following technical solution: a high-precision smooth edge grinding machine, comprising a frame, a grinding mechanism is provided on the upper surface of the frame, and a clamping mechanism is provided on the upper surface of the frame and in front of the grinding mechanism;

[0007] The grinding mechanism includes a support frame, a connecting frame, a rotating shaft, a smooth grinding disc, a fixing frame, a cooling water pipe, a spray head and a driving member.

[0015] Furthermore, the clamping mechanism includes a driving motor, a guide rail, a moving block, two synchronous shafts, two lens clamps, an adjusting cylinder and a connecting plate. The driving motor is fixed to the upper surface of the frame and is located in front of the support frame. The guide rail is fixed to the left side of the upper surface of the frame.

[0017] Furthermore, a rotating hole is opened on the right side of the moving block, and a bearing is fixed to the inner wall of the rotating hole, and the synchronous shaft on the left side is fixed to the inner wall of the bearing.

[0019] Furthermore, a sliding opening is provided on the upper surface of the frame, and the connecting plate is slidably connected between the front and rear inner walls of the sliding opening.

[0020] By adopting this technical solution, the clamping mechanism can be quickly adjusted according to the thickness and shape of the lens, thereby improving the adaptability and operating efficiency of the equipment.

[0021] Furthermore, a sliding groove is provided on the lower surface of the moving block, and the moving block is slidably connected to the outer side of the guide rail through the sliding groove, and buffer pads are fixed on opposite sides of the two lens clamps.

[0022] By adopting this technical solution, not only is the smooth sliding of the moving block on the guide rail ensured, but the direct contact between the lens clamp and the lens is also reduced through the buffer pad, thus avoiding possible damage and improving the clamping safety and lens protection.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0025] 2. This high-precision smooth edge grinding machine has a clamping mechanism that realizes rapid clamping and releasing of lenses through the coordinated work of the drive motor and the adjusting cylinder.

[0038] The working principle of the above embodiment is:

[0039] (1) The optical lens is precisely clamped in place by the clamping mechanism 3 to ensure that the lens is stable and correctly aligned with the grinding area. The grinding motor 282 is started, which drives the shaft 23 to rotate through the extension shaft 281 and the transmission belt 285.

The movement of the connecting plate 37 drives the moving block 33 to move along the outer side of the guide rail 32. The movement of the moving block 33 causes the left synchronous shaft 34 to follow the movement, thereby making the left lens clamp 35 fit with the other side of the optical lens. The lens clamps 35 on both sides clamp the lens to complete the clamping and fixing of the optical lens, ensuring that the lens is stable and motionless during the grinding process. Start the drive motor 31, and the motor output shaft drives the synchronous shaft 34 to rotate.
