The utility model discloses its compact structure, the theory of operation is clear, and when carrying out parts machining with the lathe, the outer circular cone that utilizes positioner closely cooperates with the internal cone hole of lathe spindle, adjusts the screw rod in the middle of the positioner, can reach the purpose of lathe control length location when the processing work piece, has effectively solved the lathe when the processing work piece, and the length location takes time, hard this problem, and location simple to operate has improved parts machining's precision, has also improved parts machining production efficiency.
Description
Technical field
The utility model belongs to Machining Technology field, relates to a kind of positioner, relates to a kind of positioner for lathe process specifically.
Background technology
Lathe is traditional metal cutting machine, be commonly used to the slewing parts such as working shaft-like or dish class, during processing parts, operator is according to pattern requirement, makes cutter carry out machining to workpiece, finally process qualified part by the movement locus constantly changing cutter.No matter be engine lathe or numerically controlled lathe, its main shaft, knife rest and tailstock are all the most basic component units, machine tool chief axis is axle lathe driving workpiece or cutter rotate, when lathe process workpiece, especially process longaxones parts, owing to there is axiality, the requirement of run-out tolerance equally accurate, at Workpiece fixing, problems such as often occurring time-consuming, effort is installed, both have impact on the requirement on machining accuracy of part, have impact on again the production efficiency of part processing.
Utility model content
The purpose of this utility model is the deficiencies such as, effort time-consuming for the location and installation occurred in current lathe long-shaft parts machining process, a kind of lathe process positioner is provided, novel structure, location and installation are convenient, the precision of part processing can be improved, also can improve part processing efficiency.
The technical solution of the utility model is: a kind of lathe process positioner, comprise matching used lathe spindle, it is characterized in that: described positioner is by tapered sleeve, screw rod and also cap composition, the outside of described tapered sleeve is tapered sleeve outer conical surface, the inside of described tapered sleeve is tapered sleeve internal thread hole, described tapered sleeve outer conical surface coordinates with lathe spindle inner circle taper hole and is connected, one end of described screw rod is movably connected in described tapered sleeve internal thread hole, described and cap is arranged on the other end of described screw rod, by tightening described also cap, described screw rod location is fixed in described tapered sleeve internal thread hole.
Described tapered sleeve outer conical surface is identical with the tapering of lathe spindle inner circle taper hole.
Described tapered sleeve inside has tapered sleeve internal thread hole, and tapered sleeve internal thread hole is through hole, and the internal thread in tapered sleeve internal thread hole is consistent with the external screw thread specification of screw rod.
The end diameter of described tapered sleeve is less than cylindrical hole aperture in lathe spindle, and the outside diameter of tapered sleeve is in lathe spindle outside diameter and lathe spindle between cylindrical hole aperture.
Described pitch has inner hexagonal hole, and inner hexagonal hole is blind hole.
The beneficial effects of the utility model are: a kind of lathe process positioner that the utility model provides, this positioner is by tapered sleeve, coordinate with lathe spindle after screw rod and also cap composition and use, its compact conformation, operation principle is clear, in-use automotive bed carries out part and adds man-hour, the inner circle taper hole of the outer cone of positioner and lathe spindle is utilized to closely cooperate, screw rod in the middle of regulating positioning device, lathe controls length location object when processing work can be reached, efficiently solve lathe when processing work, length location is time-consuming, this problem of effort, location and installation is convenient, improve the precision of part processing, also improve part processing efficiency.
