Description
Technical field
The present invention relates to a kind of CNC milling machine, particularly the cutter changing device of CNC milling machine.
Background technology
In the automatic tool changer of CNC milling machine, need between tool magazine and milling machine spindle, transmit and load and unload cutter, in the prior art, adopt a kind of manipulator, this manipulator, needs and will put back to tool magazine with the cutter of crossing during its tool changing with a clamping part, then from tool magazine, take out new cutter, with new Cutting tool installation manner to the milling machine spindle of milling machine.Its not part be: above-mentioned two processes can not be carried out simultaneously, and therefore, tool change time is long.
Summary of the invention
The purpose of this invention is to provide that a kind of Digit Control Machine Tool is two moves knife system, make its tool-changing speed fast, tool change time is short.
The object of the present invention is achieved like this: the two knife systems of moving of a kind of Digit Control Machine Tool, 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 hinged with connecting rod, connecting rod and L shaped clamping limb one end are hinged, the free end of described L shaped clamping limb is corresponding with arc opening, and L shaped clamping limb middle part is hinged with cantilever; The axis of the rotating shaft of rotation tool magazine, lift shaft, milling machine spindle parallels; When lift shaft rotated in the upper limit position, the arc opening of an end can grip the shank of the cutter in the tool magazine just, and the arc opening of the other end can grip the shank of the cutter on the milling machine spindle just.
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, promoting L shaped clamping limb conflicts from the side at the shank of the cutter that grips, 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 °, and with the cutter transposition on the cantilever, lift shaft rises again, the cutter that changes is inserted tool magazine, simultaneously new cutter is inserted on the milling machine spindle, then, the piston rod of two-way cylinder is return, spurring L shaped clamping limb returns, 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 present invention can realize 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 the free end of described L shaped clamping limb matches for the shank side with cutter.Locking is during cutter, and the arc part on the L shaped clamping limb abuts in the shank side of cutter just, mutually acts synergistically with arc opening on the cantilever, with cutter locking, so that the plug cutter is changed.
As a further improvement on the present invention, described rotating knife lab setting can guarantee that milling machine table has enough large usable floor area outside the workbench of milling machine.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is partial enlarged drawing of the present invention.
Wherein, 1 rotation tool magazine, 2 cutters, 3 cantilevers, 4 lift shafts, 5 two-way cylinders, 6 connecting rods, 7L clevis gripping arm, 8 milling machine spindles, 9 arc openings.
The specific embodiment
The present invention is further illustrated below in conjunction with figure.
As shown in the figure, move knife system for a kind of Digit Control Machine Tool is two, comprise the rotation tool magazine 1 that can lay some cutters 2, rotation tool magazine 1 is arranged on outside the workbench of milling machine, can guarantee that milling machine table has enough large usable floor area; Be provided with lift shaft 4 between milling machine spindle 8 and the rotation tool magazine 1, be centrosymmetric on the lift shaft 4 and stretch out two cantilevers 3, cantilever 3 ends one side is provided with the arc opening 9 that matches with cutter 2 shanks, be fixed with two-way cylinder 5 on the cantilever 3, the piston rod external part of two-way cylinder 5 is hinged with connecting rod 6, connecting rod 6 is hinged with L shaped clamping limb 7 one ends, and the free end of L shaped clamping limb 7 is corresponding with arc opening 9, and L shaped clamping limb 7 middle parts and cantilever 3 are hinged; The axis of the rotating shaft of rotation tool magazine 1, lift shaft 4, milling machine spindle 8 parallels; When lift shaft 4 rotated in the upper limit position, the arc opening 9 of an end can grip the shank of the cutter 2 in the tool magazine just, and the arc opening 9 of the other end can grip the shank of the cutter on the milling machine spindle 8 just.
