Abstract
The invention provides a flexible servo-actuated clamp used for milling of a thin-walled workpiece. The flexible servo-actuated clamp comprises a bottom plate, on which multiple cross-shaped sliding tables are fixed. Each cross-shaped sliding table is equipped with a vertical lifting platform. Each vertical lifting platform is provided with a sucking disc by means of a sucking disc rod or a main ball by means of a universal ball bearing. A shaft equipped with a sucking disc is a positioning shaft. A shaft equipped with a main ball is a servo-actuated shaft. Conversion can be achieved between each servo-actuated shaft and each positioning shaft of each sucking disc by replacing each sucking disc rod with each universal ball bearing and switching a control mode to a positioning mode. In the meantime, the flexible servo-actuated clamp used for milling of the thin-walled workpiece has following beneficial effects: all shafts and the bottom plate can be freely disassembled and assembled so that a flexible function can be fully shown; workpiece deformation is effectively reduced during a milling process; and machining precision of the workpiece is improved.
Description
Technical field
The present invention relates to milling tool field, specifically the flexible servo-actuated fixture of a kind of thin-wall part milling.
Background technology
The application of thin-wall part in modern aerospace field is increasingly extensive, but due to Thin-walled Workpiece complex structure, poor rigidity, under cutting force effect, easily produces larger machining deformation, is difficult to the machining accuracy ensureing workpiece.During high-rate wireless LAN thin-walled frame clsss part, due to the removal of material, the rigidity of workpiece changes thereupon, and cutting force causes workpiece deformation to cause the change of actual milling depth, finally causes Workpiece Machining Accuracy undesirable.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides the flexible servo-actuated fixture of a kind of thin-wall part milling, effectively can reduce the workpiece deformation in milling process, improves Workpiece Machining Accuracy.
The present invention includes base plate, base plate is fixed with some cross slid platforms, each cross slid platform is all provided with vertical lift platform, each vertical lift platform is provided with sucker by sucker bar or is provided with cue ball by multi-directional ball bearing.Installing suctorial axle is locating shaft, and the axle being provided with cue ball is servo axis, can change between servo axis and sucker locating shaft, only needs multi-directional ball bearing to be changed to sucker bar, is station-keeping mode by control mode switch.
Further improvement, described flexibility servo-actuated back shaft XY axle is parallel with workpiece coordinate axle, and initial point overlaps.
Further improvement, described multi-directional ball bearing has tapering, can reduce unnecessary interference.
Further improvement, described cue ball is nylon material, prevents from scratching workpiece.
Beneficial effect of the present invention is: control system can position the switching between axle control model and servo axis control model, embodies flexibility function, effectively can reduce the workpiece deformation in milling process, improves Workpiece Machining Accuracy.

Fig. 4 is servo axis top view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Front view of the present invention and top view are respectively as shown in Figure 1 and Figure 2, comprise base plate 1, base plate 1 is fixed with some cross slid platforms 2, each cross slid platform 2 is all provided with vertical lift platform 3, each vertical lift platform 3 is provided with sucker (locating shaft control model) by sucker bar 4 or is provided with cue ball 7(servo axis control model by multi-directional ball bearing 6, as shown in Figure 3 and Figure 4).
Servo axis has three degree of freedom, realizes two-axle interlocking in process.Fixture control system receives axis feeding data (adopting OPC data acquisition technology) from machine tool control system, then controls servo axis and follows main axle moving, keep necessary support in the regional area of tool sharpening.Servo axis is contacted by multi-directional ball bearing cue ball with workpiece, guarantor to arbitrariness; The Structure deformation of nylon material, ensure that workpiece is not scratched.
Can change between servo axis and sucker locating shaft, only need multi-directional ball bearing to be changed to sucker bar, be station-keeping mode by control mode switch.Meanwhile, can disassembled and assembled freely between each axle and base plate, fully demonstrate flexibility function.
During installation, adjust location axle and sucker, make sucker position workpiece in place and fix, simultaneously according to the installation site of workpiece scope determination servo axis to be processed, adjustment servo axis height, makes cue ball just contact with bottom workpiece.
Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
