Abstract
The invention provides a workpiece clamping device for machining. The workpiece clamping device for machining comprises an outer chuck, an inner chuck and a locking nut. The outer chuck is provided with an inner conical face, the inner chuck is provided with an outer conical face matched with the inner conical face of the outer chuck, the shaft neck portion of the outer chuck and the locking nut are of a threaded matching structure, the conical portion of the inner chuck is located in a conical hole of the outer chuck, the end, close to the locking nut, of the inner chuck is an annular boss type end, slotted holes with the identical width are formed in the conical portion of the inner chuck in the axial direction at equal intervals, one ends of the slotted holes extend to the end face of the small end of the conical portion of the inner chuck, and the annular boss type end of the inner chuck abuts against the inner bottom of the locking nut. The workpiece clamping device for machining enables clamping and retreating of workpieces to be convenient and effortless, clamping on the workpieces is reliable, the surfaces of the workpieces cannot be damaged, and locating pads do not need to be reserved on the ends of the workpieces.
Description
Technical field
The present invention relates to the clamps of lathe, the work holder of especially machined.
Background technology
When machined being carried out to axial workpiece on lathe at present, the claw disc type joint one end to part normally one end of part to be processed being stretched into lathe is fixed, for this reason, general needs are reserved certain length surplus and are used as locating pad in one end of part, or special welding one segment process dop, to form enough withdrawing spaces or surpassed distance space, after completing processing, excise locating pad part again, and end face is processed by drawing, cause waste of material, and increase processing cost.In addition, in process, part can receive the power of axial, the gyratory directions that cutter applies, for the part of not reserved locating pad, easily cause damage to piece surface, claw disc type joint, to the fixed degree of part also bad control, also exists the problem of inconvenient operation.
Summary of the invention
The object of this invention is to provide a kind of convenient mounting and clamping, it is firm to clamp, and can not cause the machined work holder of damage to piece surface.
For this reason, machined work holder of the present invention, comprise outer chuck, interior chuck and lock nut, outer chuck is provided with inner conical surface, interior chuck is provided with the male cone (strobilus masculinus) matched with outer chuck inner conical surface, the collar of outer chuck and lock nut are thread matching structure, the tapered portion of interior chuck is arranged in the bellmouth of outer chuck, one end of the nearly lock nut of inner clip head rest is the desk-top end of convex annular, the equally spaced in the axial direction slotted eye offering same widths of tapered portion of interior chuck, slotted eye one end extends to the small end end face of inner clip head tapered portion always, the desk-top end of convex annular of interior chuck and the inner bottom part of lock nut are abutted together.
During use, one end of outer chuck is fixed on the clamping head of lathe, by one end of workpiece through inserting in interior chuck after the centre bore on lock nut, use spanner rotation lock nut subsequently, lock nut outside chuck carries out axially-movable while threaded line is rotated, thus chuck axial displacement in promoting, because outer chuck maintains static, and for taper seat coordinates (inclined-plane coordinates) between outer chuck with interior chuck, therefore radially-inwardly shrink while interior chuck axial displacement and firmly grasp workpiece, playing the effect that workpiece one end is fixed.After work pieces process is good, rotate backward lock nut, interior chuck removes the grasp to workpiece, so just can be extracted out from interior chuck by workpiece very easily.
Further, lock nut offers the plural counterbore being used for coordinating with spanner rotation lock nut, so just available spanner directly inserts in counterbore, and pull spanner and carry out rotation lock nut, the shape of periphery even can be made in the periphery of lock nut.Outer chuck is provided with axially extending bore, can be used for discharging cutting and cutting fluid.
The present invention makes the clamping of workpiece and exits easy to operate, laborsaving, to the reliable clamping of workpiece, to surface of the work not damaged, in workpiece termination without the need to reserved locating pad.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below by specific embodiment, the present invention is described in detail.
As Fig. 1, shown in Fig. 2, machined work holder of the present invention, comprise outer chuck 1, interior chuck 2 and lock nut 3, outer chuck 1 is provided with inner conical surface, interior chuck 2 is provided with the male cone (strobilus masculinus) matched with outer chuck 1 inner conical surface, collar and the lock nut 3 of outer chuck 1 are thread matching structure, the tapered portion of interior chuck 2 is arranged in the bellmouth of outer chuck 1, interior chuck 2 is the desk-top end 5 of convex annular near one end of lock nut 3, the equally spaced in the axial direction slotted eye 4 offering same widths of the tapered portion of interior chuck 2, slotted eye 4 one end extends to the small end end face of interior chuck 2 tapered portion always, the desk-top end 5 of convex annular of interior chuck 2 is abutted together with the inner bottom part of lock nut 3.
During use, one end of outer chuck 1 is fixed on the clamping head of lathe, by one end of workpiece 6 through inserting in interior chuck 2 after the centre bore on lock nut 3, use spanner rotation lock nut 3 subsequently, lock nut 3 outside chuck 1 carries out axially-movable while threaded line is rotated, thus chuck 2 axial displacement in promoting, because outer chuck 1 maintains static, and for taper seat coordinates (inclined-plane coordinates) between outer chuck 1 with interior chuck 2, therefore radially-inwardly shrink while the axial displacement of interior chuck 2 and firmly grasp workpiece 6, play the effect that workpiece 6 one end is fixed.After work pieces process is good, rotate backward lock nut 3, interior chuck 2 removes the grasp to workpiece, so just can be extracted out from interior chuck 2 by workpiece very easily.The clamping of workpiece and exit easy to operate, laborsaving, to the reliable clamping of workpiece, to surface of the work not damaged, in workpiece termination without the need to reserved locating pad.
Lock nut 3 offers the plural counterbore 7 being used for coordinating with spanner rotation lock nut 3, so just available spanner directly inserts in counterbore 7, and pull spanner and carry out rotation lock nut 3, the shape of periphery even can be made in the periphery of lock nut 3.Outer chuck 1 is provided with axially extending bore 8, can be used for discharging cutting and cutting fluid.
Claims (2)
