Problems solved by technology

[0003] It is true that the above-mentioned slewing mechanism changes the linear motion into a rotation mode, so as to realize the purpose of controlling the rotation of the components, but the backlash problem in the meshing relationship between the gear and the rack affects the positioning accuracy of the components when they stop after rotation; Otherwise, the above-mentioned slewing mechanism must be equipped with a pressure cylinder structure at both ends of the rack, which not only increases the cost but also takes up space.

Abstract

The invention discloses a swing mechanism for driving a part of a machine tool to rotate. The swing mechanism comprises a base, a rotating shaft, a driving mechanism and a connecting rod mechanism, wherein, the rotating shaft penetrates through the base and can rotate in place, and one end of the rotating shaft is used for being connected with the part; and the driving mechanism comprises a push-pull rod which can bear acting force to move back and forth, and the push-pull rod drives the rotating shaft to rotate through the connecting rod mechanism, and therefore, the rotating angle of the rotating shaft can be accurately controlled.

Description

technical field [0001] The present invention relates to processing tools; in particular, it refers to a rotary mechanism for driving the parts of the machine tool to rotate. Background technique [0002] In the field of machine tools, it is often necessary to actuate and rotate specific components, such as a tool changing arm of an automatic tool changing mechanism or a type of changing disc. The known mechanism for performing the aforementioned actions is a rotary mechanism that includes a rotating shaft, a gear, and a rack. When it is a part of the rotating shaft, it can drive the components combined at one end of the rotating shaft to generate corresponding rotation. [0003] It is true that the above-mentioned slewing mechanism changes the linear motion into a rotation mode, so as to realize the purpose of controlling the rotation of the components, but the backlash problem in the meshing relationship between the gear and the rack affects the positioning accuracy of the...
