Abstract
The utility model relates to a tool replacing device of a numerically-controlled miller in the technical field of millers. The tool replacing device comprises a rotary tool magazine capable of being used for placing a plurality of tools. A lifting rotating shaft is arranged between a miller main shaft and the rotary tool magazine. Two overhanging arms extend from the lifting rotating shaft in a central symmetry mode. One side of the end portion of each overhanging arm is provided with an arc-shaped opening, wherein the arc-shaped openings are matched with the handle portions of the tools. Two-way air cylinders are fixed on the overhanging arms. Piston rod extending ends of the two-way air cylinders correspond to the arc-shaped openings. Axes of a rotating shaft of the rotary tool magazine, the lifting rotating shaft and the miller main shaft are parallel. When the lifting rotating shaft rotates at an upper limit position, the arc-shaped opening at one end can exactly grasp the handle portion of each tool in the tool magazine, and the arc-shaped at the other end can exactly grasp the handle portion of a tool on the miller main shaft. After piston rods of the two-way air cylinders extend out, the end portions of the piston rods are abutted against the handle portions of the grasped tools from the side faces. By means of the tool replacing device of the numerically-controlled miller, the operation of taking a new tool and replacing an old tool can be carried out at the same time, tool replacing speed is quick, tool replacing time is short, and therefore machining efficiency of a machine tool can be improved.

The utility model content
The purpose of this utility model provides a kind of tool changing device of CNC milling machine, makes its tool-changing speed fast, and tool change time is short.
The purpose of this utility model is achieved in that a kind of tool changing device of CNC milling machine, comprise the rotation tool magazine that to lay some cutters, be provided with lift shaft between milling machine spindle and the rotation tool magazine, be centrosymmetric on the lift shaft and stretch out two cantilevers, described cantilever end one side is provided with the arc opening that matches with tool shank, be fixed with two-way cylinder on the described cantilever, the piston rod external part of two-way cylinder is corresponding with arc opening, and rotating shaft, the lift shaft of rotation tool magazine parallel with the axis of milling machine spindle; When lift shaft rotates in the upper limit position, the arc opening of one end can grip the shank of the cutter in the tool magazine just, the arc opening of the other end can grip the shank of the cutter on the milling machine spindle just, and after the piston rod of two-way cylinder stretches out, conflict from the side at the shank of the cutter that grips in the end of this piston rod.
During this device work, the rotation tool magazine can be laid some cutters, the milling machine spindle end of milling machine installs one cutter, lift shaft can elevating movement, when lift shaft is positioned at the rotation of upper limit position, the arc opening of one end can grip the shank of the cutter in the tool magazine just, the arc opening of the other end can grip the shank of the cutter on the milling machine spindle just, at this moment, the piston rod of two-way cylinder stretches out, conflict from the side at the shank of the cutter that grips in the end of this piston rod, cutter is locked, then the downward tractive of lift shaft, cutter in the rotation tool magazine and the cutter on the milling machine spindle can be extracted simultaneously, then the rotary milling machine main shaft rotates 180 °, with the cutter transposition on the cantilever, lift shaft rises again, and the cutter that changes is inserted tool magazine, simultaneously new cutter is inserted on the milling machine spindle, then piston rod is return, the angle that the lift shaft backward rotation is certain is abdicated the processing space of milling machine spindle, finishes exchanging knives process one time, in the said process, the rotation tool magazine, the lift shaft rotational angle, all need to adopt digital control, to realize the accurate plug of cutter.Compared with prior art, the utility model can be realized getting simultaneously new cutter and change old cutter, and its tool-changing speed is fast, and tool change time is short, can improve the working (machining) efficiency of lathe.
For ease of cutter being locked the arc that described piston rod end matches for the shank side with cutter.
As further improvement of the utility model, described rotating knife lab setting can guarantee that milling machine table has enough large usable floor area outside the workbench of milling machine.
