Description
Technical field
The utility model is related to jig technical fields, and in particular to a kind of lathe thin wall cylinder clamp for machining.
Background technology
A kind of hand-held bipyramid ringfeder centering Fixture for Gear-shaving is disclosed in the patent document that publication No. is CN105665845A,
Workpiece can be positioned by the way of bipyramid ringfeder, but this scheme using when there are many limitations, and
It is not suitable for the clamping of thin wall cylinder, as a result of bipyramid ringfeder, is squeezed from both ends to centre, the centre of bipyramid ringfeder is hanging,
Thing is not supported, therefore it is easy to appear centres fully to expand when squeezing, or even both ends expansion occurs
The case where middle shrinkage, and then occur expanding non-uniform phenomenon.
Utility model content
For the defects in the prior art, the utility model provides lathe thin wall cylinder clamp for machining, realizes so that bipyramid
The effect that ringfeder integrally uniformly can adequately expand.
In order to achieve the above objectives, lathe thin wall cylinder clamp for machining provided by the utility model, including quiet mandrel, moving mandrel,
Bipyramid ringfeder and pull rod；The fixing end of the quiet mandrel is arranged on lathe, and the free end of the quiet mandrel is in end contraction
Outer cone axial plane is arranged, and the pressed end of the moving mandrel is also in the outer cone axial plane setting that end is shunk, the quiet mandrel and described dynamic
Mandrel is axially arranged with through-hole；The fixing end of the pull rod is connect with reciprocating drive unit, and the free end of the pull rod is worn successively
Quiet mandrel and the through-hole of moving mandrel are crossed, the free end of the pull rod is combined with the nut limited to the moving mandrel；The bipyramid
The endoporus of ringfeder in the outside inner cone hole face setting of big end, the bipyramid rise be set on the quiet mandrel and the moving mandrel it
Between, the inner conical hole face at bipyramid ringfeder both ends is adapted to the outer cone axial plane of quiet mandrel, moving mandrel respectively, in the endoporus of bipyramid ringfeder
In in be cased with spring, the both ends of the spring bear against the pressed end of the free end and the moving mandrel of the quiet mandrel.
The technical principle and technique effect of this programme are as follows：Before being limited to thin wall cylinder, first by back and forth driving dress
It sets, quiet mandrel and moving mandrel is separate, therefore bipyramid ringfeder will be in loose state；Then thin wall cylinder is limited, it will
It is sleeved on bipyramid ringfeder outside thin wall cylinder, starts reciprocating drive unit, pull rod drives moving mandrel to the side of quiet mandrel by nut
Movement, moving mandrel and quiet mandrel are drawn close, due to the inner cone of moving mandrel and the male-tapered structure and bipyramid ringfeder of quiet mandrel opposite side
Hole coordinates, therefore bipyramid ringfeder will be radially expanded, and the thin wall cylinder being sleeved on outside on bipyramid ringfeder will be positioned.Since bipyramid rises
The middle part of set is equipped with spring, and spring can play in centre and place phenomenon hanging in the middle part of bipyramid ringfeder, in moving mandrel and quiet core
When axis is drawn close, spring can be supported effectively always in centre, is avoided bipyramid ringfeder middle shrinkage, is ensured that bipyramid rises
Set is whole uniformly adequately to be expanded, uniform location thin wall cylinder.Pull rod is only exerted oneself from side, therefore the workpiece used can
With longer, dismounting is also more convenient.
Further, the free end of the quiet mandrel is extended with positive stop lug boss into spring, on the one hand can be carried out to spring
Positioning is fixed, and is on the other hand avoided moving mandrel and quiet mandrel from excessively drawing close and is caused irreversible damage to spring and bipyramid ringfeder,
Bipyramid ringfeder is avoided excessively to expand damage thin wall cylinder.
Further, the end face of the positive stop lug boss be equipped with control reciprocating drive unit by compressing switch, in moving mandrel and quiet
It when mandrel is drawn close, will set out by compressing switch, and then stop the work of reciprocating drive unit, avoid there is a phenomenon where overloading,
Bipyramid ringfeder is avoided excessively to expand damage thin wall cylinder.
Further, it is extended with positive stop lug boss in the pressed end spring of the moving mandrel, on the one hand spring can determined
Position is fixed, on the other hand avoids moving mandrel and quiet mandrel from excessively drawing close and causes irreversible damage to spring and bipyramid ringfeder, keeps away
Exempt from bipyramid ringfeder and excessively expands damage thin wall cylinder.
Further, the side wall of the quiet mandrel is axially arranged with pin hole, and guide pin is sliding combined in the pin hole, described to lead
It is fixed in moving mandrel to pin fixing end, one side guide pin can be that moving mandrel be oriented to, and another aspect guide pin can be with
It is supported for spring, avoids the occurrence of the case where spring is offset inwardly from.
Further, the side wall of the pull rod is axially arranged with bar limit slot, and the quiet mandrel is radially provided with caging bolt, institute
It states caging bolt to extend inwardly into bar limit slot, caging bolt can limit the movement travel of pull rod, avoid double
Cone ringfeder excessively expands damage thin wall cylinder.
