Problems solved by technology
[0005] (1) The current measurement method adds a force measuring device to the original structure, and the additional mass is too large, which limits the measurement accuracy of small friction force
[0006] (2) Adding a load cell to the shift fork of the limit support structure changes the real annular polishing state, and the measurement results cannot accurately reflect the actual situation, nor can it be applied to the actual annular polishing process
[0007] (3) The traditional annular polishing equipment has been greatly changed, which increases the equipment cost

The invention discloses an integrated device for limit support and friction online monitoring in the process of ring polishing. A dumbbell-shaped groove is provided on the shift fork of the traditional limit support device, and the side of the shift fork at the groove is Paste the strain rosette, monitor the strain value in real time during the ring polishing process to solve the friction force between the workpiece and the tool disc, and further reflect the stability of the ring polishing state of the workpiece. Since the present invention does not place the entire ring polishing machine on the sliding table to generate a large additional mass, the accuracy of friction force measurement is improved, and the requirement for measuring friction force when the workpiece size is small or the pressure is low is met. Since the present invention does not add additional mechanisms, only dumbbell-shaped grooves are processed on the original shift fork, which does not change the original ring polishing process state, and further improves the effectiveness of friction measurement. Because the present invention makes little changes to the traditional ring polishing machine, the structure is simplified, and the cost of upgrading and transforming the equipment is reduced.
Description
technical field [0001] The invention relates to the technical field of ring polishing, in particular to an integrated device for limit support and on-line monitoring of friction force during the ring polishing process. Background technique [0002] With the continuous development and application of optical technology, the demand for planar optical components continues to increase. In order to achieve high-precision and high-surface-quality machining of planar optical elements, it is necessary to perform annular polishing on the workpiece. The stability of ring polishing process is very important to improve its processing efficiency. The friction force on the workpiece during annular polishing is closely related to the material removal process. Therefore, online monitoring of friction force can help improve the stability and control ability of the annular polishing process, and provide technical support for the improvement of processing efficiency and yield. [0003] At pre...
