Automatic tool changer and tool changing method thereof

Abstract

The invention discloses an automatic tool changer and a tool changing method thereof. The automatic tool changer comprises a tool changer body and cutter heads; the tool changer body is provided witha tool magazine, a carriage, a mechanical arm, a paw, the cutter heads, empty slots, a feed screw, a machine tool, a lifting base, a rotating arm, an exchange hand, a spindle head, a tool, a guide rod, a lifting guide rial, tool clamping claws, radiating slots, a guide rial driving motor and a tool holder; the tool magazine of the tool changer body is internally provided with a plurality of cutterheads which can be turned for indexing, and each cutter head is provided with one empty slot and the radiating slots which can be used for installing a plurality of tools; and the both sides of eachradiating slot are provided with the tool clamping claws and telescopic pins so that the tools in the radiating slots can be clamped firmly and prevented from being rotated. The automatic tool changerhas the advantages of steady and stable tool changing process, simple structure and easy maintenance.

Description

technical field [0001] The invention relates to the technical field of automatic tool changing devices, in particular to an automatic tool changing device and a tool changing method thereof. Background technique [0002] With the development of science and technology, the manufacturing industry has higher and higher requirements for machining precision. Traditional machining equipment has long been unable to meet the increasingly demanding process requirements. Therefore, CNC machine tools, a highly automated machining process, were born. Equipment, CNC machine tools adopt CNC system to automatically control the cutting, feeding and other actions of the machine tool, which can realize precise control of cutting amount and greatly improve production efficiency. Drilling machining center is a kind of multi-purpose CNC machine tool. Its spindle drives the tool to rotate, and various processing procedures such as drilling, boring, and milling can be implemented by changing diffe...
