The present invention relates to an ARMLESS AUTOMATIC TOOL CHANGER (ATC), and more particularly, a tool mounted on a tool magazine assembly (TOOL MAGAZINE ASSEMBLY) during a tool change process and a workpiece placed on a table surface. Of machine tools with up / down moving structure to prevent the damage of tools and workpieces, to utilize the space of machine, and to reduce the number of items that cannot be processed through a wide range of machining operations It relates to an armless automatic tool changer.

In general, the Armless Automatic Tool Changer is a tool used to move a tool from a tool magazine to a spindle of a machining center in a conventional automatic tool changer (ATC) or vice versa. It refers to a method of automatically changing a tool by a tool magazine of a disk having a constant direction and a stroke of a spindle (STROKE) by removing a tool change arm (ARM).

Conventional armless automatic tool changer, a gear motor (GEAR MOTOR), a tool magazine assembly installed on the lower portion of the gear motor, a disk plate assembly (DISK PLATE ASSEMBLY) to which the gear motor is fixed, and the disk Left and right transport LM guides for guiding linear movement of the plate assembly, the body (BODY) of the automatic tool changer (ATC) to which the left and right transport LM guide is fixed, the body and It is fixed to one side of the disk plate assembly is composed of a left / right moving cylinder for linearly moving the disk plate assembly.

The conventional armless automatic tool changer according to the above-described configuration is a gear fixed to the disc plate assembly and the disc plate assembly by operating force of a left / right moving cylinder when the tool must be changed while machining is in progress. The tool magazine assembly coupled to the lower side of the motor and the gear motor is linearly moved to the main shaft to clamp the tool used in the main shaft to the empty gripper installed in the tool magazine assembly, and the main shaft is the tool shank. After rising to the height, the tool magazine assembly is dividedly rotated by the gear motor to rotate the tool to be used for the next work to the tool change position, and then the spindle is lowered to clamp the tool to the spindle, and the spindle side of the tool magazine assembly. Stroke back from the position to the standby position (STROK After the retreat, the operation is completed.

However, since the conventional armless automatic tool changer can only move left / right linearly by the left / right moving cylinder and the left / right transfer LM guide, the tool and the table mounted on the tool magazine assembly during the tool change process. The interference between the height of the workpiece placed on the upper surface, there is a problem such as damage to the tool and the workpiece, productivity of the machine due to the space utilization and limited processing of the machine.

An object of the present invention is to solve such a conventional problem, the height of the tool and the workpiece mounted in the tool magazine assembly that occurs when only the linear movement of the left / right moving cylinder and the left / right transfer LM guide Armes automatic tool of machine tool with up / down moving structure, further installed vertically moving up / down moving cylinder and up / down moving LM guide for guiding up / down moving to solve the interference between parts. It is to provide an exchange device.

As a means for achieving the above object, the configuration of the present invention is fixed to the disk plate assembly and the disk plate assembly by the operating force of the left and right moving cylinder fixedly installed on the body and disk plate assembly of the automatic tool changer (ATC). An armless automatic tool that linearly moves to the clamping position of the main shaft along a left / right transfer LM guide fixed to the body of the automatic tool changer (ATC) is coupled to the lower side of the installed gear motor. In the exchange device,

A saddle disposed on one side of the rear surface of the disc plate assembly and linearly moving along the left and right LM guides; An up / down moving cylinder fixedly installed at an upper side of the saddle and vertically moving; A plate fixed to the up / down moving cylinder to fix the vertical movement of the disc plate assembly; An LM guide disposed on one side of the rear surface of the plate for guiding the up / down transfer; It is fixed to the upper and lower one side of the saddle is made up and down to check the up / down movement of the disk plate assembly comprises a sensor.
