Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a vertical swing device for the spindle of a machining center. Background Technique

[0002] A machining center is a numerically controlled machine tool mainly used for precision metal processing. It is usually used in the manufacturing industry, including fields such as aerospace, automotive manufacturing, mold manufacturing, and medical devices. The machining center has a multi-axis motion system and can move and rotate in different directions to achieve precise machining of workpieces.

[0003] The spindle swing mechanism of a machining center is usually used to achieve multi-axis machining operations, thereby increasing the flexibility and efficiency of the machining center. The spindle swing mechanism allows the spindle to swing or rotate in the vertical direction so that cutting can be performed at different angles during the machining process. The existing spindle swing mechanisms of machining centers have low swing accuracy, so a vertical swing device for the spindle of a machining center needs to be designed.
