A tool changer 10 includes a tool change arm 40 having tool holding portions 42, 52 at ends thereof, a support shaft supporting the tool change arm 40, a rotation mechanism including a rotation drive motor 25 and rotating the tool change arm 40 about an axis of the support shaft, a forward/backward movement mechanism including a forward/backward movement drive motor 13 and moving the tool change arm 40 forward and backward along the support shaft, and a mount base 11 having the rotation drive motor 25, the forward/backward movement drive motor 13 and the support shaft mounted thereon. The tool changer has a restraining member 60 provided thereon which restrains movement of the tool change arm 40 in a direction along the support shaft by engaging with the tool change arm 40 positioned at an original position.

A protection tool for an electronic drill provides various functions when drilling is carried out. The electronic drill has a front end with a through hole located at the front end and a drill head extending through out the through hole. The protection tool is moveably mounted at the front end of the electronic drill along an operation direction. A guard plate includes a pore aligning with the through hole and provides pass way for the drill head. A supporting frame is assembled with the guard plate and is moveably mounted at the front end of the electronic drill along the operation direction, so that the guard plate is positioned at a variable distance from the front end according to the movement of the supporting frame with respect to the front end.

A tool magazine includes at least one tool carriage movable along a circulation path. The tool holders each have tool pot sockets to which the tool pots are mountable. The tool holders are disposed pivotably about a pivot axis with respect to the at least one tool carriage. The tool pot sockets include a first and second tool pot sockets. An angle is created in a pivoting direction about the pivot axis between a first tool pot mounted to the first tool pot socket and a second tool pot mounted to the second tool pot socket. The turning device turns each of the tool holders about the pivot axis at a position on the circulation path. The tool pot stopper positions each of the tool pots and stops one of the first tool pot and the second tool pot at a pivotable location in the pivoting direction.

A motor-driven machine tool includes a drive unit and a tool changing magazine with tool chambers that are placed into a transfer position adjacent to a tool receptacle to be loaded. The machine tool includes a tool changing device with a slide element that is arranged in operative connection with a tool. The slide element is moved by an operating element into a first position for accepting a tool from or transferring a tool to the tool chamber and into a second position to drive the tool. The slide element is fixed in the second position by a blocking element that is brought out of operative connection with the slide element by a transfer element to move the slide element from the second position to the first position. The slide element is arranged in indirect contact with the blocking element to move the blocking element by the transfer element.

A tool changer is composed of a support shaft, a forward/backward movement drive motor moving the support shaft upward and downward, a rotation drive motor rotating the support shaft about an axis, a tool change arm having tool grippers formed at both ends thereof, and an air blow mechanism discharging compressed air to a tool and a next tool gripped by the tool grippers. In tool change using this tool changer, in a positioning operation, the tool change arm is rotated by degrees and compressed air is discharged toward the tool and the next tool by the air blow mechanism.

A tool changer for a machine tool is provided with a spindle head, tool magazine, rotating shaft, and magazine drive motor. The tool magazine is provided with a tool-magazine power transmission unit. The tool-magazine power transmission unit and a magazine-drive-motor power transmission unit engage with each other at all times between a proximity position and a separated position relative to the spindle head of the tool magazine.

An electronic drill with revolving replaceable drilling heads includes a housing, a driving unit, a rotary cover, and a plurality of drill heads. The housing has an opening, a through hole, a containing room connected therebetween. A motor container is disposed within the containing room to contain a motor of the driving unit. The rotary cover is assembled to the housing and is rotatable so that the plurality of drill heads coupled to the rotary cover is moveable freely in a rotary track between the motor container and the housing. One of the drill heads may be rotated to be aligned with a rotary hole of a gear set driven by the motor and pushed forward for use. The drill head can also be retracted backward and replaced in the electronic drill by rotating the rotary cover, so that another drill head can be pushed outward for use.

A servo-driven tool unclamping system for a machine tool contains: a tool changing unit, a tool unclamp unit, and a servo control unit. The tool changing unit includes a cam box, a first servo motor for driving the cam box, a driving shaft driven by the cam box, and a tool change arm driven by the driving shaft. The tool unclamp unit includes a spindle, a transmission assembly, and a second servo motor. The servo control unit includes a main controller, a first servo drive and a second servo drive both electrically connected with and controlled by the main controller. The first servo drive and the second servo drive are also electrically coupled with the first servo motor and the second servo motor and numerically control the tool changing unit and the tool unclamp unit, hence the tool change arm operates, and the spindle clamps and unclamps each tool.

A tool changer includes a tool magazine, a support shaft disposed to have a center axis parallel to an axis of a tool spindle, a drive mechanism for rotating the support shaft about the center axis and moving the support shaft in the axial direction, three tool change arms fixed to the support shaft and each having a tool holding unit, a tool transfer mechanism for transferring a tool pot from the tool magazine to a standby position, and a provisional placing pot disposed at a provisional placing position. The tool changer starts a tool change operation in a state where a tool to be attached to the tool spindle, a tool to be used next, and a tool to be used after the next tool are held by the tool holding units of the tool change arms.

The disclosure relates to column module, more particularly it is relating to a multi-axis column module. The multi axis column module comprising a support structure of predetermined shape; at least one Automatic Tool Changer [ATC] consisting a tool magazine ensconcing a plurality of tools mounted onto the support structure, a drive unit with a spindle connected to said tool magazine, a gripper arm connected to the spindle of the drive unit; and at least one ram housing having at least one spindle at center and is mounted over the support structure. The disclosure also provides for a method of swapping tools in the multi axis column nodule and method of assembling the multi axis column module.
