Description
Technical field
The present invention relates to a kind of flexible knife bars of grinding and polishing, belong to technical field of mechanical processing.
Background technique
For machining accuracy and the higher workpiece of surface quality requirements, especially using mold as the various with higher of representative
The workpiece of hardness is often processed in machining center or on CNC milling machine when processing request is not achieved in the machining accuracy of lathe,
A little grinding allowance is stayed, is subsequently placed on grinding machine, drawing requirement is ground to.In this way not only due to secondary clamping directly brings fiber crops
It is tired, and need to recalibrate centering.Secondary clamping bring error is difficult to avoid that, and when recalibrating centering, is needed
It takes a significant amount of time, especially for the higher part of requirement on machining accuracy, clamping calibrates the time it takes often again
Far more than the grinding time thereafter.Even if final processing quality meets drawing requirement, efficiency is also greatly reduced.In addition must also
There are grinding machine or other grinding-polishing equipment, in the workpiece that processing generally requires, these equipment will be idle, and cause equipment and sky
Between the wasting of resources.And the workpiece required in face of different quality, the machine tool accessory needed is also not quite similar, especially for list
Part, small lot processing, often because accessory problem needs biggish investment.
The technique being directly ground in machining center or on CNC milling machine after processing at present has existed, for solution
Certainly various technique requirements, bistrique/polishing wheel/abrasive wheel etc. is also all kinds of.However these techniques are there are a common drawback,
I.e. its knife bar used belongs to rigid knife bar, and with grinding or the progress of grinding, bistrique/polishing wheel/abrasive wheel occurs dynamic and grinds
Damage, rigid knife bar can not carry out wear-compensating again, cause under same parameter, and front and back grinding/polished amount is different.Typical situation
It is larger to will appear beginning stock removal, is ground at all to the later period less than it is qualified by the higher work pieces process of processing request to be difficult in this way.
Summary of the invention
The purpose of the present invention is current technology there are the shortcomings that, provide a kind of grinding and polishing flexible knife bar, pass through flexibility
Knife bar carries out dynamic compensation to the abrasion that bistrique/polishing wheel/abrasive wheel occurs, and then guarantees machining accuracy.
Technical solution is as follows:
A kind of flexible knife bar of grinding and polishing, including knife bar, spring, sliding screw element, fastening pressure cap and stop nut,
Middle knife bar is the different step-like round bar of both ends outer diameter, is provided with a plurality of guide chute in the lesser one end of outer diameter, guide chute is most
Head is provided with external screw thread；Sliding screw element is annular construction member, and one end is internally provided with sliding rail corresponding with guide chute, another
End offers external screw thread；Fastening pressure cap is a tapped annulus；Spring pocket is mounted in the outer of the lesser one end of knife bar outer diameter
The guide chute insertion of side, knife bar is slided in the sliding rail of screw element, and bistrique/abrasive wheel/polishing wheel case is outer sliding screw element
Outside screw thread, fastening pressure cap is connect with sliding screw element male end, and stop nut is connected with knife bar male end.
Further, 180 ° are separated by fastening pressure cap periphery to open there are two through-hole, fastening pressure cap convenient for loading and unloading；Fastening pressure
Cap is uniformly arranged along the circumference concaveconvex structure towards bistrique/abrasive wheel/polishing wheel mounting surface, to lock bistrique/abrasive wheel/throwing
Halo.
Further, stop nut adjusts bistrique/abrasive wheel/polishing by adjusting the circle number for screwing in knife bar male end
Take turns maximum distance axially extending at work.
Further, the material selection hard alloy steel or high-speed steel of knife bar, and by the heat of quenching and high tempering
Reason；Spring is high-intensitive compressed spring.
Further, knife bar is installed on machining center or CNC milling machine after securing bistrique/abrasive wheel/polishing wheel,
It is polished directly machining center or CNC milling machine or to completion machining to the workpiece that machining is crossed has been carried out
Workpiece carries out size by a small margin and modifies, to improve workpiece surface quality.
The utility model has the advantages that
1) present invention carries out dynamic compensation by the abrasion that flexible knife bar opposite grinding head/polishing wheel/abrasive wheel occurs, without frequency
Numerous replacement bistrique/abrasive wheel/polishing wheel, and can guarantee machining accuracy, improve grinding and polishing efficiency.
2) by the common hand lapping such as bistrique/abrasive wheel/polishing wheel/polishing articles, clamping is in CNC milling machine or processing
In the heart, being suitable for such equipment, that certain machining accuracy and surface quality requirements can not be done directly by machining is higher
Work pieces process.It is placed on grinding on grinding machine again after can avoid machining, leads to necessary secondary clamping and again to workpiece school
The error and trouble that quasi- centering generates.The plenty of time is saved, production efficiency is improved.
