For further understanding of the features and technical contents of the present invention, it please refers to below in connection with of the invention detailed
Illustrate and attached drawing, however, the drawings only provide reference and explanation, is not intended to limit the present invention.
Detailed description of the invention
With reference to the accompanying drawing, by the way that detailed description of specific embodiments of the present invention, technical solution of the present invention will be made
And other beneficial effects are apparent.
Fig. 1 is a kind of structural schematic diagram suitable for the mach submissive system of processing of robot of the present invention.
Fig. 2 is a kind of structure chart of the floating cutter arbor suitable for the mach submissive system of processing of robot of the present invention
Specific embodiment
Further to illustrate technological means and its effect adopted by the present invention, below in conjunction with preferred implementation of the invention
Example and its attached drawing are described in detail.
Please refer to Fig. 1, Fig. 2, it includes: that robot 1, tool are fast that one kind, which being suitable for the mach submissive system of processing of robot,
End 2, Force control system 3, high-speed electric main shaft 4, knife handle 5, floating cutter arbor 6, mill 7 are changed, the robot 1 passes through tool quick change end
2 and Force control system 3 connect high-speed electric main shaft 4,4 one end of high-speed electric main shaft is equipped with knife handle 5, and knife handle 5 is connected by floating cutter arbor 6
Connect mill 7.
Wherein, the floating cutter arbor 6 includes: knife bar shell 8, knife handle connecting rod 9, ball spline mother 10, constant force spring 11,
Hubcap 12, splined shaft 13, cutter connecting rod 14, screw 15, check washer 16, anti-back jackscrew 17,8 lower section of knife bar shell
Knife handle connecting rod 9 is installed knife handle connecting rod 9 is fixed in knife bar shell 8 by anti-back jackscrew 17,9 front end of knife handle connecting rod
There is splined shaft 13 between ball spline mother 10,9 front end surrounding of knife handle connecting rod is provided with constant force spring 11, the cutter connection
Bar 14 is connected to female 10 one end of ball spline, and ball spline mother 10 is fixed in knife bar shell 8 by hubcap 12, and screw 15 is by axis
End cap 12 and knife bar shell 8 are locked, and check washer 16 is equipped between screw 15 and hubcap 12.
Further, the knife handle 5 of 4 automatic clamping of high-speed electric main shaft with floating cutter arbor 6.
Further, the robot 1 drives high-speed electric main shaft 4 to do spatial movement by quick change.
Further, the robot 1 can feed back the stress in bruting process with Force control system 3, and adjust
1 motion pose of robot.
Further, it is connected through a screw thread between the mill 7 and knife handle 5, is connected through a screw thread between mill 7, knife handle 8, milling cutter,
The milling cutter is mounted on floating cutter arbor 6.
By flanged joint, robot 1 drives high-speed electric main shaft 4 to do by fast replacing device for power control sensor and robot 1
Spatial movement, electro spindle 4 can automatically grab knife handle 5, and knife handle 5 clamps floating cutter arbor 6 by clip spring structure, and knife bar 5 and mill 7 are logical
Cross threaded connection.
While floating cutter arbor 6 can produce high speed rotation, compression constant force spring 11 generates axial floating, and keeps constant pressure
Power.
Before bruting process, the constant force spring 11 for being suitble to knife bar is selected according to process requirement.In bruting process, cutterhead is close to
Workpiece surface movement, 4 high speed rotation of electro spindle, cutterhead are ground workpiece, are mutated smaller or cutter track variation ratio encountering workpiece configurations
When larger, and 1 speed of service of robot it is relatively high when, generation is compressed axially knife bar 5 simultaneously atwirl,
Shape deviation is compensated rapidly and polishing power is kept to meet technique requirement.Under conditions of shape is mutated clearly, knife bar 5 floats
Amount can only eliminate part deviation, and at this moment robot 1 reduces movement velocity, and the force snesor feedback stress of Force control system 3 is excessive,
The variation of 1 pose of robot guarantees that cutter is bonded default cutter track, and polishing power is kept not change.It is by controlling 1 power of robot
System 3 and 6 structure of floating cutter arbor combine composition robot polishing floating cutter arbor system, greatly improve 1 power change perceived of robot
Range and precision, thus solve the problems, such as robot 1 polish it is complex-curved during technological effect it is bad.
