Problems solved by technology
The existing tool bar swing device generally rotates the swing bar around two axes perpendicular to each other in space, thereby controlling the tool bar to swing arbitrarily within a certain range, and avoiding the interference between the tool bar and the workpiece when processing complex curved surfaces, but because the tool bar Oscillation is a continuous process. The position of the spherical tool changes continuously with the swing of the tool bar. This requires that the two axes that control the tool bar swing must be linked with the three linear axes in the center of the tool to process an ideal curved surface. Because of the five-axis The linkage CNC system has a complex structure and cumbersome programming, which greatly affects the application of this technology

The present invention belongs to the field of mechanical manufacture technology, and is especially one tool bar swinging unit for spherical cutter. The tool bar swinging unit for spherical cutter includes one spherical cutter, one tool bar, one tool bar seat and one swinging seat, and the spherical cutter is mounted to the head of the tool bar. It features the swinging axis of the tool bar through the sphere center of the spherical cutter, the tool bar seat with upper convex cambered surface, and the swinging seat with lower concave cambered surface fitting the convex cambered surface in the tool bar seat. The present invention has unchanged position of the spherical cutter and can realize machining of complicated curved surface.
Description
technical field [0001] The invention belongs to the category of mechanical manufacturing, in particular to a spherical cutter bar swinging device. Background technique [0002] When using a spherical tool to process a workpiece with a complex curved surface, in order to avoid interference between the tool holder and the workpiece, the movement and rotation of the spherical tool in all directions is often completed by the tool holder swing. The existing tool bar swing device generally rotates the swing bar around two axes perpendicular to each other in space, thereby controlling the tool bar to swing arbitrarily within a certain range, and avoiding the interference between the tool bar and the workpiece when processing complex curved surfaces, but because the tool bar Oscillation is a continuous process. The position of the spherical tool changes continuously with the swing of the tool bar. This requires that the two axes that control the tool bar swing must be linked with th...
