The locking mode of locking, for details, reference can be made to application number CN201220474787.1, a kind of entitled " more function for machining center
Can precision stage " patent document, this will not be detailed here.
Now to this reality by taking the process of airplane turbine disk workpiece 1 of its tongue-and-groove 1a with certain inclination alpha and cone angle beta as an example
The course of work for applying the workbench for broaching lathe of example is described: turbine disk workpiece 1 to be processed passes through clamp assembly
Assembly 81 is fixed on index table 80, wherein the turbine disk can rotate with index table 80 and arbitrarily divide within the scope of 360 degree
Degree, the rotation center for now arranging index table 80 is A axis, and index table 80 is set on cross slid platform, and cross slid platform is slidably connected
On arc slide 20, arc slide 20 is slidably connected on the arcwall of fixed pedestal 10, and fixed pedestal 10 again can be by turning
Axis 500 is rotatably connected in base platform, wherein and the shaft 500 between agreement fixed pedestal 10 and platform of machine tool 50 is B axle,
The axial line for arranging the cylindrical groove of fixed pedestal 10 is C axis of the arc slide 20 relative to the fixed sliding of pedestal 10 rotation, agreement
The direction of feed (being moved forward and backward direction) of cross slid platform is Z axis, and correspondingly, that arranges cross slid platform moves left and right direction (up and down
Moving direction) it is Y-axis.Turbine disk workpiece 1 is fixed on index table 80, and then arc slide 20 is driven by the first driving mechanism
Arcwall along fixed pedestal 10 is rotated around C axis, and (such as Fig. 3 is shown at arc slide at the inclination angle of adjustment turbine disk workpiece 1
In -45 ° of heeling condition, Fig. 5 shows the heeling condition that arc slide is in+45 °), arc slide 20 slides into setting position
It postpones, arc slide 20 is locked in the setting position by the first locking assembly 40, meanwhile, fixed pedestal 10 is in the second driving knot
It under the driving of structure, is rotated on the horizontal plane of platform of machine tool 50 around B axle, adjusts the cone angle of turbine disk workpiece 1, fixed pedestal
After 10 slide into setting position, fixed pedestal 10 is locked in the setting position by the second locking assembly 70, turbine disk workpiece 1
It, can drawing of the cross slid platform to workpiece on the placed side 23 by being set to arc slide 20 after the completion of inclination alpha and cone angle beta adjust
It cuts position to be adjusted and locked and (moved along Y-axis), and past in the longitudinal direction by cross slid platform control workpiece
Multiple mobile (moving along Z axis) is completed the feeding adjusting of workpiece and is locked, and after the completion of above each axis is adjusted, workpiece has been in
Full locking state can be broached at this time by outer profile of the broaching cutters to turbine disk workpiece 1, and one of tongue-and-groove has been broached
Cheng Hou can be carried out indexing adjusting by index table 80 and lock the broaching for carrying out next tongue-and-groove.
The workbench for broaching lathe in the present embodiment has the advantages that multiple: the arc slide 20 of workbench first can
Slidably in the arc chute 100 of fixed pedestal 10, so that the relatively fixed pedestal 10 of arc slide 20 forms one
Cradle mechanism, the workpiece being arranged on the arc slide 20 can be rotated with the cradle mechanism, and may be locked in corresponding
Oblique angular position, the cutter facilitated on lathe process the workpiece, and especially external profile is with certain inclination angle
Disc type work carries out broaching molding；Secondly, the fixed pedestal 10 of the workbench can on platform of machine tool 50 around the shaft 500 into
Row rotation, its adjustable cone angle state of workpiece to be processed being set on fixed pedestal 10 in this way, and then cutter is facilitated to tooth
The disc type work of shape or flute profile with cone angle carries out highly-efficient processing molding；Workbench in the present embodiment is applied in which can be convenient
Wire pulling method, the especially tongue-and-groove of airplane turbine disk are carried out to disc type work on high-end horizontal side broaching machine and high-end vertical external broaching machine
Wire pulling method, specifically, according to the inclination angle of turbine disk workpiece 1 to be processed and cone angle size, can by the driving mechanism of each axis,
The turbine disk is precisely adjusted corresponding machining posture, then by the linear movement of broaching tool, turbine disc mortise can be completed
Wire pulling method greatly improve processing without such as needing to prepare and replace multiple frock clamps in the prior art
Efficiency reduces production cost, guarantees processing quality.In addition, the workbench can also be used for the Milling Process of other workpiece, it can
The process equipment requirement of corresponding milling machine is effectively reduced, guarantees processing quality, realizes stability and high efficiency processing.
