Computer numerical control machining center based on quick and automatic tool changing system

Abstract

The invention discloses a computer numerical control machining center based on a quick and automatic tool changing system. The computer numerical control machining center comprises a machine tool body, an automatic tool changing system, a servo driving device and a control system, wherein the automatic tool changing system comprises an automatic tool changing control device, an electric lifting platform, a horizontal rotating base, a disc-type tool magazine, and an installation-height-adjustable manipulator which is used for changing tools; a rotating shaft is arranged below the middle of the installation-height-adjustable manipulator; an installation height adjusting mechanism which is used for adjusting the installation height of the installation-height-adjustable manipulator is arranged on the rotating shaft; the automatic tool changing control device comprises an automatic tool changing controller, a rotation angle detection unit I, a lifting height detection unit, a rotation angle detection unit II, a tool model input unit, an installation height detection unit and a data storage unit. The computer numerical control machining center is reasonable in design, simple and convenient to operate, high in intelligence degree, good in using effect, and shorter in tool changing time. The installation height of the manipulator is adjustable, a control mode is simple, and adjustment of the installation height can be conveniently realized.

Description

technical field [0001] The invention relates to a numerical control machining center, in particular to a numerical control machining center based on a fast automatic tool change system. Background technique [0002] The CNC machining center is a CNC machine tool with a tool magazine and an automatic tool changer. Typical machine tools include boring and milling centers and turning centers. In the CNC machining center, after the parts are clamped and positioned once, they can perform centralized and continuous processing of multiple processes and multiple processes, which greatly reduces the number of machine tools. Production set-up times are further shortened due to reduced auxiliary times for loading and unloading workpieces, changing and adjusting tools, and a significant reduction in tooling. At the same time, because the positioning error caused by multiple installations is reduced, the position accuracy between the processing surfaces is greatly improved. Among them...

Problems solved by technology

In actual use, when the existing height-adjustable manipulator is used for tool change, it is necessary to move the height-adjustable manipulator upward synchronously when the tool is taken out from the tool magazine; The height-adjustable manipulator is moved down synchronously, so the tool installation process of inserting the tool into the spindle cannot be completed synchronously when the tool is put back into the tool magazine, and the removal of the tool from the machine tool spindle cannot be completed synchronously when the tool is taken out from the tool magazine process, so the required tool change time is relatively long, which greatly affects the processing efficiency of CNC machine tools
