Abstract

This utility model relates to the field of CNC machine tool technology, and more particularly to a braking device for a milling rotary table. The device includes a rotary table, a piston, a reset assembly, and a detection assembly. The bottom of the rotary table has a hydraulic chamber, and the piston slides within the hydraulic chamber. Hydraulic oil flows into the hydraulic chamber, causing the piston to move downwards. The reset assembly is located inside the rotary table, with its lower end connected to the piston, driving the piston to reset. The detection assembly is installed above the rotary table, with one end connected to the piston. This utility model, through the reasonable installation of the reset assembly, such as installing a disc spring above the piston, provides sufficient deformation space, greatly enhancing the reset force of the disc spring, allowing the rotary table to return to its working state more quickly after braking, thus improving the working efficiency of the milling rotary table. Furthermore, the detection assembly is used to detect the braking function of the rotary table, making the judgment of the braking status more accurate, enabling faster diagnosis and repair, and improving the safety of the production workshop.
