Automatic tool changing device of simple numerical control machine center

Abstract

The invention discloses an automatic tool changing device of a simple numerical control machine center. The automatic tool changing device of the simple numerical control machine center is easy and convenient to operate, reliable in performance and high in working efficiency. The automatic tool changing device of the simple numerical control machine center is composed of a base, a stepping motor, a coupler, a rotating shaft, a rolling bearing, a bearing support, a telescopic cross arm, pneumatic cylinders, clamping mechanisms and a control system. The pneumatic cylinders are arranged at the two ends of the telescopic cross arm. The clamping mechanisms are fixedly connected to main shafts of pneumatic cylinders. The telescopic cross arm is fixedly connected to the upper end of the rotating shaft. The lower end of the rotating shaft is connected with the stepping motor through the coupler. The control system comprises a main controller, a D / A converter, an A / D converter, a stepping motor actuator and an electromagnetic valve.

Description

technical field [0001] The invention relates to a simple automatic tool changing device for a numerically controlled machining center, more specifically, it relates to an automatic tool changing device for a numerically controlled machining center in which a main shaft and a cutter head perform consistent tool loading and unloading actions. Background technique [0002] The automatic tool changing device of the CNC machining center can select different tools from the tool magazine and install them on the main shaft according to the needs of actual production and processing, and automatically complete the tool changing action, which not only improves the work efficiency, but also increases the installation accuracy. However, most of the automatic tool changing devices of CNC machining centers on the market are multi-degree-of-freedom manipulators, which are not only complicated to control, inconvenient to maintain, but also relatively expensive. However, some low-degree-of-fr...

However, most of the automatic tool changing devices of CNC machining centers on the market are multi-degree-of-freedom manipulators, which are not only complicated to control, inconvenient to maintain, but also relatively expensive.

However, some low-degree-of-freedom manipulators not only have low positioning accuracy and repeat positioning accuracy, but some manipulators that change tools from the side are prone to collisions with the machine tool spindle and cutter head, and the clamping effect of the clamping mechanism is poor.
