Strong five-shaft linked swing head mechanism of large-power electric spindle

Abstract

The invention relates to the technical field of machine tool devices, in particular to a strong five-shaft linked swing head mechanism of a large-power electric spindle. The strong five-shaft linked swing head mechanism comprises an A-shaft swing head mechanism and a B-shaft swing head mechanism. The A-shaft swing head mechanism is driven by a first double-servo-motor unit, a first speed reducer is respectively connected below the first double-servo-motor unit, a gear is respectively arranged below each speed reducer, the two gears together drive an A shaft, two sides of the A shaft are clamped by first hydraulic clamping devices, and crossed roller bearings are supported at two ends of the A shaft. The B-shaft swing head mechanism is driven by a second double-servo-motor unit, a second speed reducer is respectively connected below the second double-servo-motor unit, an arc rack is arranged in front of the second speed reducers, a B shaft is arranged at the lower end of the arc rack, two sides of the B shaft are clamped by second hydraulic clamping devices, a deep groove ball bearing and a turntable bearing support are respectively arranged at two ends of each second hydraulic clamping device, and a rack balancing cylinder is arranged at the tail end of the B shaft. The A shaft and the B shaft respectively achieve closed-loop control through a first circular grating and a second circular grating.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to a powerful five-axis linkage swing head mechanism for a high-power electric spindle. Background technique [0002] At present, both domestically and internationally, electric spindles with low power and low torque are used on five-axis machine tools, or mechanical spindle structures are used to achieve high-torque cutting. The low-power and low-torque electric spindle five-axis linkage machine tool can no longer meet the needs of parts processing in the aerospace industry. Although the mechanical spindle meets the high-torque cutting, the mechanical spindle makes the five-axis swing head structure too complicated and lengthy, prone to mechanical failure . Contents of the invention [0003] In order to overcome the disadvantages of the existing mechanical spindle that the five-axis swing head structure is too complicated and prone to mechanical failure, the prese...
