Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a chemical polishing device for special-shaped workpieces. Background Technique

[0002] When an optical lens is processed and prepared, it contains a variety of workpieces with different shapes and sizes. After each workpiece is prepared, it often needs to be polished. Currently, there are two common polishing methods. One is physical polishing, that is, the workpiece is polished by grinding. However, due to the diversity of workpieces in the optical lens, it is difficult to polish and position the smaller workpieces. The other is chemical polishing. By placing the workpiece in a chemical polishing solution, pits and scratches are eliminated under the corrosion of the polishing solution. This method is more suitable for polishing special-shaped workpieces or smaller workpieces. However, when processing workpieces by chemical polishing, it is difficult to salvage the smaller workpieces, and the polishing solution attached to the outside of the workpiece easily affects the neutralizing solution and the cleaning solution, resulting in the need to frequently replace the neutralizing solution and the cleaning solution, with a high cost. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a chemical polishing device for special-shaped workpieces, which can be used for grinding special-shaped workpieces or smaller workpieces, facilitating the processing and production of optical lenses. Moreover, this polishing device is convenient for salvaging smaller or special-shaped workpieces, improving its polishing efficiency. At the same time, after salvaging, it is dried by centrifugation to avoid affecting each other among the polishing solution, the neutralizing solution, and the cleaning solution, reducing the replacement frequency of various solutions, thereby reducing the polishing cost, and effectively solving the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A chemical polishing device for special-shaped workpieces, including a fixing plate. On the upper side of the fixing plate, there are a first box body, a second box body, and a third box body, and the tops of the first box body, the second box body, and the third box body are all open. In the middle of the side of the fixing plate, a support rod is fixed, and at the top of the support rod, a mounting plate is rotatably installed. On the side of the mounting plate, there is a mounting frame with adjustable height. On the side of the mounting frame, a placement box is rotatably arranged. Through holes are evenly opened on the side of the placement box, and a driving component for driving the placement box to rotate is arranged in the mounting frame.

[0005] As a preferred technical solution of the utility model, the driving component includes a driving motor installed inside the mounting frame. A connecting frame is fixed on the driving shaft of the driving motor, and the upper part of the side of the placement box is fixedly connected with the side of the connecting frame.

[0006] As a preferred technical solution of the utility model, an electric telescopic component is installed on the side of the mounting plate, and the mounting frame is installed at the telescopic end of the electric telescopic component.

[0007] As a preferred technical solution of the present utility model, a limiting plate is fixed on the upper part of the side surface of the support rod. The limiting plate is located at the lower part of the side surface of the mounting plate, and the limiting plate is rotatably connected to the mounting plate. A positioning column is fixed at the top of the support rod, and positioning grooves are evenly formed on the side surface of the positioning column. A positioning component that is stuck in the positioning groove is arranged on the side surface of the mounting plate.

[0008] As a preferred technical solution of the present utility model, the positioning component includes a mounting seat fixed on the side surface of the mounting plate. A positioning rod is slidably mounted in the mounting seat, and a restraint plate is fixed on the side surface of one end of the positioning rod close to the positioning column.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For the chemical polishing device for special-shaped workpieces exemplified by the present utility model, the workpiece to be polished is placed in the placement box. Then, the electric telescopic component is controlled to work to drive the mounting frame to move so as to place the placement box in the first box body. The polishing liquid enters the placement box through the through holes and contacts the workpiece. The polishing liquid corrodes the outside of the workpiece to eliminate pits or scratches, increasing the smoothness of the workpiece surface, thereby playing a polishing role.

[0013] 2. For the chemical polishing device for special-shaped workpieces exemplified by the present utility model, during the polishing process, the driving motor is controlled to work to drive the placement box to rotate, which plays a role in stirring the polishing liquid in the first box body.

Then, the driving motor is controlled to work to drive the placement box to rotate at a high speed. The residual polishing liquid in the placement box and the polishing liquid adhered to the side surface of the workpiece are separated from the side surface of the workpiece under the action of centrifugal force, avoiding the influence on the neutralizing liquid caused by more polishing liquid on the side surface of the workpiece during the subsequent neutralization process, and reducing the replacement frequency of the neutralizing liquid.

[0015] 4. In the chemical polishing device for special-shaped workpieces according to the embodiment of the present invention, during the rotation of the mounting plate, the positioning column rotates relative to the mounting plate, and the positioning rod slidably arranged on the side of the mounting plate restricts the rotation of the positioning column under the action of the positioning spring. When the positioning rod restricts the positioning column, the placement box is located directly above the first box body, the second box body or the third box body, which is convenient for the use of this polishing device.

[0031] During use:

[0032] Place the workpiece to be polished in the placement box 12, and then control the electric telescopic assembly 8 to work to drive the mounting frame 9 to move and place the placement box 12 in the first box body 2. The polishing liquid enters the placement box 12 through the through hole and contacts the workpiece.
