Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment, in particular to a brake hydraulic control device. Background Art

[0002] The worktable guide rails of many vertical lathes, especially heavy-duty vertical lathes, are mostly hydrostatic guide rails. When the machine tool is working normally, a hydrostatic oil film is formed between the worktable and the base. The oil film stiffness supports the worktable and the workpiece to separate from the base. If an electrical fault such as a sudden power failure occurs in the machine tool, the main motor, hydraulic oil pump and other components will stop working, and the rotating worktable and the workpiece will continue to rotate under the action of inertia, and the hydrostatic oil film between the worktable and the base will gradually disappear. If the rotation of the worktable and the workpiece has not stopped before the hydrostatic oil film between the worktable and the base disappears, it will cause serious consequences such as damage to the worktable guide rails, or even greater danger.
