Description
Technical field
The present invention relates to Digit Control Machine Tool field, relate to Digit Control Machine Tool five-axle linkage dynamic accuracy research field, particularly relate to a kind of load-carrying checking of dynamic accuracy system.
Background technology
In field of machining, the commonly used five-axis robot of Aero-Space.Along with Processing Technology Development, various processing industries also realize five-axis robot gradually, such as boats and ships, weapon, automobile etc..5 conventional both at home and abroad axle machining center Research on Accuracy focus primarily upon the static errors model, error-detecting and error compensation aspect, less about the application technical research of dynamic accuracy error in trueness error source, owing to dynamic accuracy is more by the influence factor of processing work, processing operating mode, environment etc., modeling analysis and optimization comparatively difficulty.
At present in 5 axle machining center Research on Accuracy fields, examination criteria about trueness error is all based on virtual or uncharged test, characterize for truly studying the error in the course of processing, in no case can avoid final test specimen processing, it is necessary to set up the new evaluation criteria based on this.
Dynamic accuracy is corrected by Digit Control Machine Tool by electrical compensation, correction controls driver element mainly through closed-loop mode and compensates, each drive motor has nominal torque, when peripheral load exceedes nominal torque or transmission portion gap occurs, electrical compensation will appear from partial failure, does not reach ideal effect.Carry out checking of dynamic accuracy in the unloaded state, be the accuracy detection under unstressed effect, process part status with reality and bigger gap occurs.Checking of dynamic accuracy must be carried out in load-carrying situation and could simulate the lathe dynamic accuracy state of the best.
Determine the load-carrying dynamic accuracy of lathe, length consuming time only by the precision of processing test specimen at present, expend rapidoprint, labor intensive cost etc..
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of load-carrying checking of dynamic accuracy system.
A kind of load-carrying checking of dynamic accuracy system, it is characterized in that including: main shaft grip bolt, main shaft clamping device, fixed support section locking device, the spring of bringing onto load power and fixed support pedestal, described fixed support pedestal includes 4 fixed support section locking devices, described fixed support pedestal is provided with elastic spring, being provided with main shaft grip bolt on described main shaft clamping device, described main shaft clamping device is connected with fixed support pedestal by the spring of bringing onto load power.
