Even so, be applied to vacuum technique to realize clamping on the lathe, still have a following difficult problem workpiece: because the complex of existing vacuum cup, so there is the problem of cost rising, and have the weight problem of higher in structure aspects; The rotation of lathe spindle driving workpiece is to realize turning, and then the inevitable requirement vacuum cup also will be with the rotation of lathe spindle one superhigh speed, the contradiction between vacuum cup that will finding the solution like this determines rotates and the static pipeline.
The utility model content
The purpose of the utility model is to provide a kind of vacuum adsorption type precision meter lathe clamp mechanism, is the basis with the vacuum technique, is applied to realize on the lathe that stable clamping and drive workpiece to workpiece rotate at a high speed with lathe spindle.
For realizing above-mentioned purpose; The utility model discloses a kind of vacuum adsorption type precision meter lathe clamp mechanism, it mainly comprises: instrument chuck, sucker, sealing ring, pipeline, swivel joint, and said instrument chuck is connected on the instrument lathe; Said sucker is fixed on the said instrument chuck; Said sucker is provided with groove towards the end face of the installation position of workpiece, and said sealing ring is embedded in the said groove, and said pipeline connects said sucker and swivel joint.
Preferably, the connected mode of said instrument chuck and sucker is for being threaded.
Preferably, the connected mode of said pipeline and sucker is for being threaded.
Preferably, said sucker is after said instrument chuck, sucker, sealing ring and pipeline install, more said end face to be carried out turning processing at last by lathe tool, to obtain even curface more towards the process sequence of the end face of the installation position of workpiece.
Preferably, said sealing ring is the O RunddichtringO.
Preferably, the central axis of the moving joint of said instrument chuck, sucker, pipeline and swivel joint is located along the same line, and the main shaft gyration center of said straight line and said instrument lathe overlaps.
Compare with conventional art, the beneficial effect of the utility model is:
1, clamp mechanism can realize the stable absorption to thin-wall workpiece, and prevents that effectively workpiece from producing torsional deformation;
2, utilize vacuum technique to realize clamping, can avoid mechanical wear and prolong machine service life workpiece;
3, pollution-free, do not hinder workpiece, be suitable for the turning processing of precision component;
4, clamping time lacks, and saves the time of clamping workpiece and dismounting, effectively raises labour efficiency.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
