Description
Technical field
The invention belongs to B23Q3/06：The technical field of Workpiece clamping device.
Background technology
Fixture is widely used in the processing and manufacturing of workpiece.The plain grinding processing of shaft-like workpiece is the basis of following process,
Machining accuracy is affected to the processing of subsequent workpiece, therefore, has certain required precision to the plain grinding processing of shaft-like workpiece.
At present, axis class milling clamper often has the following disadvantages：Fixture clamping part is unadjustable, therefore a fixture can only clamp one
The workpiece of kind of specific dimensions, fixture utilization rate is low, using limited, and the fixture that while being processed at present to valve uses is mostly center
Frame, it is impossible to be processed to valve by the part that centre frame clamps.
The Chinese invention patent that Patent publication No is CN103506705A discloses a kind of adjustable valve processing of fixture
Device makes the distance between first support and second support that can adjust, before valve is clamped, makes the by pneumatic device driving
Distance increases between one stent and second support, after valve to be processed is placed, adjusts between first support and second support
Distance, by jamming of valve.In said program, the distance between first support and second support can be adjusted, so as to adjust
Along the distance of valve axial direction between stent, therefore the valve of different length can be processed, but diameter difference can not be adapted to
Valve.
When carrying out Milling Process to one section of valve, valve one end is fixed by chuck, and valve can rotate, in valve plus
During work, the section diameter being milled becomes smaller, and chuck can lead to the grasp of valve end to be milled section generation torsion, very
To leading to valve breakage.
