Abstract
Description
Technical Field
[0001] This utility model relates to the field of workbench support technology, and in particular to a workbench leveling structure. Background Technology
[0002] In the mechanical manufacturing process, the worktable of precision equipment is often affected by factors such as vibration generated during operation, changes in the load on the worktable, and sudden changes in the surface temperature of the workpiece. If it is not leveled for a long time, the tilt of the worktable will be serious, which may even affect the processing accuracy of the equipment and lead to unqualified processing quality of the workpiece. Therefore, it is necessary to perform leveling operations on the worktable of precision equipment regularly.
[0003] Typical leveling structures for precision equipment worktables simply involve setting lead screws at the four corners of the worktable, manually adjusting the height, and manually identifying whether the worktable has been successfully leveled. This is inefficient and increases the workload of the operators. Therefore, a new worktable leveling structure is needed to solve these problems. Utility Model Content
