Five-axis machine tool rotary table with damping structure

Abstract

The invention discloses a five-axis machine tool rotary table with a damping structure, and relates to the technical field of numerical control machine tools. The five-axis machine tool rotary table comprises a turntable main body, wherein the turntable main body is provided with a rotary workbench, a sunken part is arranged in the center of the upper portion of the rotary workbench, and a plurality of T-shaped grooves are evenly formed around the sunken part; the center of the rotary workbench is connected with a rotating shaft; the rotating shaft is connected with the turntable main body through a bearing; the rotating shaft is of a hollow structure, one end is connected with a shunting disc, and the other end is connected with a connecting pipe; the shunting disc is located at the sunken part, and the side wall of the shunting disc is provided with a plurality of shunting holes; the axes of the shunting holes are in one-to-one correspondence with those of T-shaped grooves; a shell of the turntable main body is provided with an oil seal and a water pipe connector; the oil seal is arranged inside the water pipe connector; and the tail end of the connecting pipe penetrates out of the oil seal and is arranged in the water pipe connector. According to the invention, water flow or cutting fluid is sprayed into the T-shaped grooves, vibration energy of mounting bolts in the T-shaped grooves can be absorbed, then the water flow slides down along the T-shaped grooves, and the vibration energy is brought out.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a five-axis machine tool turntable with a shock absorbing structure. Background technique [0002] The precision of the oscillating turntable directly affects the machining quality of the five-axis machining center. Usually, the swing table is driven by a servo motor, and the power is transmitted through the transmission structure of the mechanical system (belt wheel, worm gear, worm, etc.) to drive the table to rotate, and the table is used to fix the processing parts. Vibration will occur during the processing of parts, which will affect the processing accuracy of parts. In the prior art, the thickness and connection strength of the parts on the turntable are increased to suppress the vibration. However, this method does not eliminate the vibration energy, but through the turntable It absorbs vibration energy by itself, which will reduce the precision o...

Problems solved by technology

Vibration will be generated during the processing of parts, which will affect the processing accuracy of parts. In the prior art, the thickness and connection strength of parts on the turntable are increased to suppress the vibration. However, this method does not eliminate the vibration energy, but through the turntable It absorbs vibration energy by itself, which will reduce the precision of the turntable and affect the processing quality if it goes on for a long time
