Description

Technical Field

[0001] This utility model relates to the field of camera lens processing technology, specifically a camera lens precision polishing device. Background Technology

[0002] Camera lenses are a type of optical lens. Before being assembled onto a camera, camera lenses need to undergo multiple processing steps to meet the camera's imaging standards. These processing steps include polishing the lenses.

[0003] For example, the announcement number CN211103172U is a lens polishing device. The device includes a polishing base, a limiting plate and a polishing pad. The middle part of the bottom end of the polishing base is fixedly connected to the output shaft of a first rotating motor, and the first rotating motor is located in the middle part of the bottom end of the base. Because the above-mentioned device has a relatively simple lens clamping mechanism, it can only polish one side of the lens, which leads to reduced efficiency and cannot clamp and fix lenses of different diameters. Utility Model Content

[0004] The purpose of this invention is to provide a precision polishing device for camera lenses, in order to solve the problem mentioned in the background art that the lens clamping mechanism is relatively simple, which results in only one side of the lens being polished, leading to reduced efficiency and the inability to clamp and fix lenses of different diameters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a camera lens precision polishing device, comprising a base and a top bracket, wherein the top bracket is installed above the base; Also includes: A rotating disk is disposed between a top frame and a base. A fixed disk is movably engaged inside the rotating disk. A limiting groove is provided on one side of the inner wall of the rotating disk, and the outer side of the fixed disk is movably engaged inside the limiting groove. A clamping block is provided at the upper end of the fixed disk, and several clamping blocks are arranged in a circular array above the fixed disk. A rotating rod is provided inside the clamping block. The bottom of the rotating rod is mounted above the fixed disk through a bearing, and the upper end of the rotating rod extends above the clamping block. A second tooth is provided on the outer surface of the rotating rod on the side above the clamping block, and the second tooth is arranged in a circular array on the outer upper half of the rotating rod. A first tooth is provided on the inner wall of the rotating disk, and the first tooth is arranged in a circular array on the inner wall of the rotating disk. The first tooth and the second tooth are meshed and connected for transmission.

[0006] Preferably, a protrusion is provided on the inner side of the bottom of the rotating disk, and a rotating knob is provided at the bottom of the protrusion. The rotating knob is threadedly connected to a threaded hole on the surface of the protrusion. A pressure plate is provided at the upper end of the protrusion. The rotating knob passes through the threaded hole on the surface of the protrusion and is connected to the pressure plate. The pressure plate is movably attached to the surface of the fixed disk.

[0007] Preferably, the bottom sides of the fixed plate are symmetrically provided with brackets, the bottom of the brackets are fixed above the base, and the fixed plate is fixed between the top frame and the base by the brackets.

[0008] Preferably, the bottom of the top frame is provided with an upper polishing disc, which is located above the rotating disc, and the upper end of the top frame is provided with a first motor, which is connected to the upper polishing disc through a connecting rod.

[0009] Preferably, a lower polishing disc is provided at the upper end of the base plate, and the lower polishing disc is located below the rotating disc. A connecting frame is provided below the lower polishing disc, and a second motor is provided on the other side of the bottom of the connecting frame. The second motor is connected to the lower polishing disc through a connecting rod.

[0010] Preferably, the top frame and the base are connected by a cylinder.

[0011] Preferably, the upper surface of the base is provided with an electric push rod, and the connecting rod at the upper end of the electric push rod is connected to the bottom of the connecting frame on the side away from the second motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting up a rotating disk and a fixed disk, the camera lens is placed in the inner hole of the rotating disk and the fixed disk. Then the rotating disk is rotated so that the rotating disk rotates around the surface of the fixed disk. At this time, the first tooth rotates with the rotating disk, which can drive several rotating rods on the upper end of the fixed disk to perform synchronous transmission. The rotating rod drives the clamping block to rotate to one side so that the clamping block can be unfolded. The clamping block can be used to clamp and fix the outer edge of the lens. This clamping method can make the two sides of the lens surface suspended, which makes it easy for the upper and lower polishing disks to polish the two sides of the lens surface at the same time, thereby improving efficiency. The rotating rod is located on one side of the clamping block so that when the rotating rod rotates, it can drive the clamping block to unfold inward. At the same time, this clamping method can clamp a certain range of camera lenses, thereby improving efficiency and clamping range.

[0013] (2) By setting a protrusion on one side of the bottom of the rotating disk, the protrusion is located below the fixed disk. A rotating knob is set on the surface of the protrusion. By tightening the rotating knob, the pressure plate is made to fit against the surface of the fixed disk, so that the pressure plate contacts the surface of the fixed disk, thereby fixing the rotating disk and preventing the rotating disk from becoming loose, which would cause the clamp to loosen and the lens to fall off.
