When the upper grinding disc and the lower grinding disc of the double-end grinding machine are not parallel, the upper grinding disc and the workpiece part contact first until the upper grinding disc is fully pressed into place. When processing ultra-thin brittle materials, the upper grinding disc may only press a small part of the workpiece during the pressing process, causing the workpiece to be damaged due to excessive stress.

However, the lower grinding disc of the traditional double-end grinding machine does not have an adjustment structure for the parallelism of the upper and lower grinding discs, so when the upper grinding disc and the lower grinding disc are not parallel due to the deflection of the lower grinding disc, the lower grinding disc cannot be adjusted for parallel proofreading. Skill completion elements: the skill problem to be dealt with is to provide a double-end grinding machine lower grinding disc adjustment structure that can adjust the parallelism between the lower grinding disc and the upper grinding disc.

In order to deal with the above skill problems, the skill plan adopted in this skill is a lower grinding disc adjustment structure of a double-end grinding machine, which includes an annular lower grinding disc and a grinding disc bracket. The lower grinding disc is fixed on the upper part of the grinding disc bracket through a plurality of fixing screws, and includes three sets of adjusting screws, each set of adjusting screws includes screws and lock nuts; the grinding disc bracket includes three threaded holes, and the screws are screwed into the threaded holes from bottom up, the front end of the screw is against the bottom surface of the grinding disc.

In the above-mentioned lower grinding disc adjustment structure, the grinding disc bracket includes an annular tray, a hub, a conical disc with a small upper and a large lower and a plurality of vertical plates; The annular tray, the hub and the conical disc are coaxial, the annular tray is arranged above the conical disc, the annular tray and the conical disc are connected by the vertical plate, and the plurality of vertical plates are arranged along the circumferential direction of the annular tray. The hub is arranged in the middle of the small end of the conical disc; the lower grinding disc is fixed above the annular tray through a plurality of fixing screws, and the threaded holes are located on the annular tray.
