Mandrel hollow direct-drive type vertical-horizontal conversion swing head structure

Abstract

The invention provides a mandrel hollow direct-drive type vertical-horizontal conversion swing head structure which is simple and compact in structure, high in precision, easy to install and maintain and convenient for pipelines and cables to penetrate through. The mandrel hollow direct-drive type vertical-horizontal conversion swing head structure comprises a main shaft, a main shaft fixing piece, a shell and a hollow mandrel; the hollow mandrel is rotationally arranged in the inner cavity of the shell through a bearing, and a connecting disc is coaxially fixed to the connecting end of the hollow mandrel; a torque motor for driving the hollow mandrel to rotate is arranged between the hollow mandrel and the shell; the bearing adopts a rolling bearing, an inner ring is fixedly connected with the connecting disc, and an outer ring is fixedly connected with the shell; a tool bit is arranged at the lower part of the main shaft, and the main shaft is fixedly arranged on the main shaft fixing piece; one side of the main shaft fixing piece is fixed with the connecting disc; and the combination face of the shell, the axis of the main shaft and the axis of the hollow mandrel are arranged in a vertical-horizontal conversion mode, and the tool nose point of the tool bit is located on the axis of the hollow mandrel.

Description

technical field [0001] The invention relates to an oscillating head structure, in particular to a hollow core shaft direct-drive type vertical-horizontal conversion oscillating head structure. Background technique [0002] With the continuous development and progress of modern manufacturing industry, the requirements for manufacturing precision and production efficiency are getting higher and higher. At present, the use of vertical and horizontal automatic switching swing heads is the most advanced and fastest way, which can achieve a very high vertical and horizontal conversion rate. and efficiency, thereby improving the adaptability of the entire machining process, and the vertical-horizontal conversion swing head is the core component of the vertical-horizontal conversion turning-milling compound machining center. [0003] However, in the traditional vertical-horizontal conversion swing head, the radial bearing and the thrust bearing are designed separately. The radial an...

Problems solved by technology

[0003]However, in the traditional vertical-horizontal conversion swing head, the radial bearing and the thrust bearing are designed separately. The radial and axial connectors are designed separately, and the structure is complicated ;Secondly, the traditional vertical-horizontal conversion swing head uses a deceleration structure to connect the servo motor and the swing head. Due to the backlash of the deceleration mechanism, the positioning accuracy and repeat positioning accuracy are poor; finally, the traditional vertical-horizontal conversion swing head, the main shaft Pipes and cables are often exposed on the outside of the entire swing head. When vertical and horizontal conversion swing processing, you need to pay attention to whether the pipes and cables will interfere with the processing area, which is very inconvenient
