Abstract

The invention discloses a double-drive single-swing head for a vertical machining center. The double-drive single-swing head for the vertical machining center comprises a swing head box body, a main shaft box, a main shaft, an A-axis left driving assembly, an A-axis right driving assembly, an A-axis oil distributor assembly, an A-axis encoder assembly and a main shaft pipeline outlet unit. The A-axis left driving assembly comprises a left torque motor assembly and a left hydraulic clamping mechanism. The A-axis right driving assembly comprises a right torque motor assembly and a right hydraulic clamping mechanism. A main shaft pipeline spirally surrounds the main shaft pipeline outlet unit, and a left protective cover and a right protective cover are fixed to the left side and the right side of the swing head box body respectively. According to the double-drive single-swing head, the main shaft box is driven by the double-torque motors which are symmetrically designed, larger rotatingtorque can be provided, high dynamic characteristics and stability required by machining are guaranteed, and the problem that a rotating shaft is distorted and deformed in a traditional single-side driving mode is solved. Meanwhile, the double hydraulic clamping mechanisms are adopted, larger locking torque can be provided, the braking effect can be ensured, and the rigidity of the single swing head in the machining process is ensured.

Description

technical field [0001] The invention relates to a machining center accessory, in particular to a double-drive single-swing head for a vertical machining center. Background technique [0002] The single swing head provides one more degree of freedom for the machine tool, and provides an excellent one-stop solution for multi-angle machining parts. It is an important part of high-end CNC machine tools. At present, the driving mode of the single pendulum head on the market is mainly mechanical, and generally adopts worm gear or rack and pinion transmission. Although it has good economy, the structure is relatively bulky, the speed is generally not high, and the dynamic characteristics are poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-drive single-swing head for a vertical machining center that can ensure the high dynamic characteristics and stability required for machining. [0004] The technical so...
