The further improvement project of the utility model is, described pull bar is divided into left part, intermediate location and right part from left to right successively, the external diameter of described left part and right part equates, and being slightly larger than the internal diameter of the central through hole A of elastic expansion sleeve, the external diameter of intermediate location is equal to or slightly less than the internal diameter of the central through hole A of elastic expansion sleeve.
The utility model further improvement project is that the left part of pull bar and the left and right sides of right part are equipped with chamfering.
The utility model further improvement project is that described expansion set comprises the packing with certain taper of being located at left end, also comprises the positioning convex of being located at the packing right side and the lasso of being located at the positioning convex right side.
The utility model further improvement project is, described packing left end external diameter is less than the right-hand member external diameter, and described packing left end external diameter is equal to or slightly less than the internal diameter of the central through hole B of processing work, and packing right-hand member external diameter is greater than the internal diameter of the central through hole B of processing work; The length of packing equals or is slightly larger than the length of processing work.
The utility model further improvement project is, the external diameter of described lasso is greater than packing right-hand member external diameter, and described positioning convex external diameter is greater than the external diameter of lasso.
The utility model further improvement project is, the left part length of described pull bar and the intermediate location length of pull bar is equal to or greater than the length of packing.
The beneficial effects of the utility model are:
When carrying out the clamping of processing work with the utility model, first piston rod is stretched out, drive pull bar and move to range left, this moment, packing was in relaxed state; Annular work piece is touched positioning convex, and be nested with on packing; Pass through signal controlling, in the piston cylinder with the piston rod propelling piston, drive pull bar to the right, so that the pull bar left part presses to packing and the central through hole inwall of the annular work piece of fitting, annular work piece firmly is clamped on the utility model, and by lasso, annular work piece and lathe rotating shaft are carried out accurate axial location.From the above-mentioned course of work as can be known, carry out being fixedly clamped of annular work piece with the utility model, can fast and effeciently workpiece be clamped under the prerequisite of defective work piece contact-making surface not guaranteeing, can guarantee that the axial location of workpiece and lathe rotating shaft is accurate simultaneously.
