Abstract
The utility model discloses a kind of lathe spindle afterbody positioner, it comprises the scroll chuck of clamping work pieces and the main shaft of lathe for machining, the positioning seat matched with its outer-diameter threads is socketed with at the afterbody of main shaft, the axle center of positioning seat offers internal thread hole, internal thread hole is connected with the threaded backstay that can mate with its internal thread, and the inner face that backstay inserts main shaft contacts with the workpiece end face be connected on scroll chuck.Compared with the prior art, the utility model is by being socketed with the positioning seat matched with its outer-diameter threads at the afterbody of main shaft, the axle center of positioning seat offers internal thread hole, internal thread hole is connected with the threaded backstay that can mate with its internal thread, the inner face that backstay inserts main shaft contacts with the workpiece end face be connected on scroll chuck, like this when batch machining part, without the need in measuring workpieces one by one, improve the efficiency of the processing of workpiece.
Description
Technical field
The utility model relates to a kind of lathe spindle afterbody positioner, and a kind of lathe spindle afterbody positioner, belongs to mechanical processing and positioning technical field of tools.
Background technology
Often can relate in lathe use procedure and fix rod workpieces with clamping with three-jaw chuck; it all needs survey tool to carry out the length location of rod workpieces in each fixation procedure; this process of locating one by one exists can not quick-clamping; inefficient problem; if rod workpieces is longer simultaneously; through will unsettled easy appearance distortion after scroll chuck, and easily produce comparatively big bang man-hour adding.
Summary of the invention
The technical problems to be solved in the utility model is, provide a kind of be convenient to produce in batches can quick position clamping, lathe spindle afterbody positioner, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: a kind of lathe spindle afterbody positioner, it comprises the scroll chuck of clamping work pieces and the main shaft of lathe for machining, the positioning seat matched with its outer-diameter threads is socketed with at the afterbody of main shaft, the axle center of positioning seat offers internal thread hole, internal thread hole is connected with the threaded backstay that can mate with its internal thread, and the inner face that backstay inserts main shaft contacts with the workpiece end face be connected on scroll chuck.
Described lathe spindle afterbody positioner is with externally threaded hollow cylinder at the afterbody of main shaft, and positioning seat comprises and is wrapped in cartridge on hollow cylinder external diameter and the cylindrical member being connected backstay.
Described lathe spindle afterbody positioner, backstay is provided with and drives locking nut and antihunting push rod, and the length of antihunting push rod and the internal diameter of main shaft match.
Compared with the prior art, the utility model is by being socketed with the positioning seat matched with its outer-diameter threads at the afterbody of main shaft, the axle center of positioning seat offers internal thread hole, internal thread hole is connected with the threaded backstay that can mate with its internal thread, the inner face that backstay inserts main shaft contacts with the workpiece end face be connected on scroll chuck, like this when batch machining part, without the need in measuring workpieces one by one, improve the efficiency of the processing of workpiece.Be provided with driving locking nut on the securing lever, like this can lock in place bar position, the backstay avoiding main axis to cause turns round, and guarantees precision; By arranging antihunting push rod on the securing lever, the length of antihunting push rod and the internal diameter of main shaft match, such backstay is can not produce swing with during main axis, and backstay can play certain supporting role with workpiece end face is basic simultaneously, avoids stock class workpiece deformation.
Accompanying drawing explanation
Fig. 1 is syndeton schematic diagram of the present utility model.
Detailed description of the invention
Embodiment 1. as shown in Figure 1, it comprises the scroll chuck 1 of clamping work pieces and the main shaft 2 of lathe for machining, the positioning seat 3 matched with its outer-diameter threads is socketed with at the afterbody of main shaft 2, the axle center of positioning seat 3 offers internal thread hole, internal thread hole is connected with the threaded backstay 4 that can mate with its internal thread.
Being specially, is with externally threaded hollow cylinder at the afterbody of main shaft 2, and positioning seat 3 comprises and is wrapped in cartridge 5 on hollow cylinder external diameter and the cylindrical member 6 being connected backstay 4, and such object firmly also can connect backstay 4 by main shaft 2.Inner face during use, backstay 4 being inserted main shaft contacts with the workpiece end face be connected on scroll chuck 1, therefore rotational positioning bar 4 just can realize the axial displacement of backstay 4, to adapt to the length of different component of rod category; Backstay 4 is provided with and drives locking nut 7 and antihunting push rod 8, locking nut 7 is driven to be tightened in the end face of positioning seat 3, the revolution of backstay 4 when machine tool chief axis can be avoided like this to rotate, antihunting push rod 8 is connected to the end that backstay 4 inserts main shaft 2, the internal diameter of its length and main shaft 2 matches, when avoiding main axis like this, backstay 4 swings excessive, guarantees positioning precision.
