Automatic Tool Changer
The mechanical arm is designed to clamp ISO 50 tools and the distance between two tool axes. The axial and spin movement of hand is provided by double action hydraulic cylinders.
Mechanical arm travels along on the rolling way, which is fixed on the column, and performs the change and carrying of tools between the tools-magazine and the machine spindle.
Mechanical arm consist of a levers mechanism for gripping the tools, an arm taking off and inserting the tools in the spindle taper or in the tool station in the magazine. The unit is completed with a 180° swiveling mechanism of the arm body supporting the tool grippers.
The 180° swiveling is performed by means of a pinion-rack mechanism, hydraulically driven by a hydraulic linear motor. The axial motion in and out is achieved by means of a linear hydraulic cylinder, placed inside the mechanical arm body.
On the upper and lower sides of the mechanical arm housing, there are attached the rolls to provide the movement along the rolling guide ways. Rolls are fixed by means of brackets supporting a free swiveling fork, so that the triangle profile roll follows the guide way track. The motion of the mechanical arm on the rolling – way, between the magazine and the machine spindle, is achieved by means of a rotating hydraulic motor. A chain and pinion mechanism moves the arm along its guide way.
All movements are hydraulic, by means of linear and rotary motors, and confirmed by inductive proximity switches, mechanically limited. The tool magazine is chain type, fastened on the column by a rigid welded structure support. It is positioned in vertical plane in the backside of the column. The chain is actuated by a variable speed feed motor through a planetary gear reducer (i=1:10) and a duplex worm reducer. The wormed gear is fastened to the chain gear.
Tools magazine is designed for the tools and tool holders stocking (50/60 – tools/tool holders) and to prepare the necessary tool for the next operation, thus shortening the operating time of the machine – tool.
Tool magazine consists of a links chain and of 50/60 tool holder supports. Tool holder supports are provided with a tool clamping system with balls and springs, a ranking number and an indexing system for placing the tool. Near the driving wheel, two proximity switches are provided to count tools in the magazine – A third proximity switch is placed on the tools-magazine support and is meant to show “O” position.
