Rotating-tower-type automatic tool changer of numerical control machine tool

Abstract

The invention provides a rotating-tower-type automatic tool changer of a numerical control machine tool. The rotating-tower-type automatic tool changer comprises a tool rest, a rotating tower head, spindle heads, a spindle bevel gear, a tool changing gear, a tool changing motor, a positioning cylinder, an elevating cylinder and a spindle motor, wherein the rotating tower head is installed at a rotating tower head installing position at one end of the tool rest; the tool changing motor is installed at the top of the tool rest; the tool changing gear is installed on a rotating shaft head; a gear disc which is meshed with the tool changing gear is installed at one end of the rotating tower head; a plurality of positioning holes are formed on the gear disc; a plurality of spindle heads are distributed along the circumferential direction of the rotating tower head; one end of each spindle head stretching into the rotating tower head is connected with the spindle bevel gear; the positioning cylinder is installed inside the tool rest; the piston rod head of the positioning cylinder stretches out of the tool rest so as to be matched with the positioning holes; the spindle motor is installed inside the tool rest and is driven to ascend and descend by the elevating cylinder arranged below the spindle motor; and the rotating shaft head of the spindle motor is equipped with the bevel gear matched with the spindle bevel gear. According to the tool changing device, the spindle head is changed by using the transposition of the rotating tower head, so that the automatic tool changing function is realized.

Description

technical field [0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a turret-type automatic tool changing device for numerically controlled machine tools. Background technique [0002] At present, the turret-type automatic tool change devices of CNC machine tools at home and abroad all use transmission mechanisms such as tool disc separation mechanisms, connecting rod mechanisms, and conveyor belts to transmit power and realize certain special actions. This structural design has its shortcomings The disadvantages are: complex structure, high working noise, many mechanical failures, serious wear, difficult installation and maintenance, and long installation and maintenance time, resulting in low work efficiency, high cost, and short service life. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a turret-type automatic tool changer for...
