AI Technical Summary

Technical Problem

The indexing turntable of existing horizontal machining centers is unstable during indexing rotation, and requires lifting and lowering actions, which affects the load-bearing capacity and the rotational stability of the workpiece.

Method used

The design employs a hydraulic cylinder and piston-tooth disc. By engaging and disengaging the piston-tooth disc with the fixed and moving tooth discs, the worktable is stably supported and rotated, preventing lifting and lowering movements and enhancing load-bearing capacity and rotational stability.

Benefits of technology

It improves the load-bearing capacity and rotational stability of the worktable, ensures the stability of the workpiece during indexing rotation under load, and reduces the interference of external impurities on the turntable's operation.

Abstract

This utility model provides a machine tool indexing rotary table, belonging to the technical field of machine tool equipment. It solves the problem of unstable rotation of the worktable under load during indexing rotation in existing rotary tables. The machine tool indexing rotary table includes a slide saddle and a worktable. The worktable is supported above the slide saddle. A hydraulic cylinder is installed between the worktable and the slide saddle. The hydraulic cylinder includes a cylinder body and a piston gear plate that can slide up and down. The cylinder body is fixedly connected to the slide saddle. A fixed gear plate located below the piston gear plate is also fixedly connected to the slide saddle. A rotatable movable gear plate is sleeved on the outer periphery of the fixed gear plate. When the piston gear plate slides downward, it can engage with both the fixed and movable gear plates. When the piston gear plate slides upward, it can disengage from both the fixed and movable gear plates. A bearing is sleeved on the outer periphery of the hydraulic cylinder. The outer ring of the bearing is fixedly connected to the slide saddle, and the movable gear plate and the worktable are both fixedly connected to the inner ring of the bearing. This rotary table improves the rotational stability of the worktable during indexing adjustment.
