Workpiece disc turnover device of double-station turnover polishing machine

Abstract

The invention discloses a workpiece disc turnover device of a double-station turnover polishing machine. The workpiece disc turnover device comprises a turnover frame and a plurality of workpiece disc assemblies, wherein the turnover frame is arranged on a lifting mechanism, can be driven by a turnover driving mechanism to turn over and is provided with two working faces, and the plurality of workpiece disc assemblies are arranged on the turnover frame and located on the working faces. Each workpiece disc assembly comprises a workpiece disc which is driven by a constant-pressure driving device to move up and down along the turnover frame and is driven by a rotary driving device to rotate. According to the device, each workpiece disc assembly applies polishing pressure to the workpiece disc through an independent constant-pressure air cylinder, so that workpieces in working states can be subjected to the same pressure, the defect that due to height errors and parallelism errors between the workpiece discs, the workpieces cannot be completely attached to polishing discs be polished can be overcome, therefore, polishing pressure of the workpieces is uniform, the surfaces of the workpieces are fully polished, and the polishing precision and quality are improved.

Description

technical field [0001] The invention belongs to a polishing machine, and in particular relates to a workpiece disc turning device of a double-station turning polishing machine. Background technique [0002] With the development of industrial manufacturing technology and the reduction of the weight and size of the supplies needed for people's life and work, many parts that need to be polished, such as glass, metal, and ceramics, are getting thinner and thinner; For higher efficiency and higher precision polishing, it is necessary to adopt a single-sided polishing process, such as a flipping polishing machine that uses the upper workpiece disc to perform single-sided polishing on the workpiece. The traditional double-station flip polishing machine includes a workpiece disk and a polishing disk, the workpiece disk is on the top, and the polishing disk is on the bottom. The workpiece disc is driven by a servo motor with a reducer to rotate. The workpiece disc is installed on th...

AI Technical Summary

Problems solved by technology

[0004] There are multiple independent workpiece discs on each station. Due to the height error and parallelism error between the workpiece discs, it is impossible to make the workpiece and the polishing disc (lower disc) completely fit for polishing. Keep in contact with the polished surface of the workpiece, but the uniformity of the polishing pressure is also very poor. Polishing can only reduce the surface roughness value of the workpiece, and cannot form a good surface accuracy, resulting in poor polishing accuracy
