Abstract

The utility model provides a numerical control lathe fixture of a thin-wall barrel-shaped workpiece. The numerical control lathe fixture of the thin-wall barrel-shaped workpiece can solve the problems that after a workpiece is clamped by the prior thin-wall barrel-shaped workpiece numerical control lathe fixture, and the perpendicularity of the end surface of the workpiece and the axial line and the circular runout of the outer circle of the workpiece and the axial line are oversize, guarantees smooth assembling and disassembling of the workpiece, and improves machining efficiency. The numerical control lathe fixture of the thin-wall barrel-shaped workpiece comprises a mandrel, and is characterized by further comprising a positioning plate and a tensioning mechanism, the mandrel is provided with a positioning ring surface integrated with the mandrel, the positioning plate is sleeved on the mandrel, the positioning plate and the positioning ring surface are axially fixed through a bolt, and the tensioning mechanism is coaxially sleeved on the mandrel and is axially locked and positioned through a locking nut and the positioning plate.

Description

A kind of digital control lathe clamper of thin-wall tube-shaped workpiece

Technical field

The utility model relates to the numerical control Vehicle Processing field of thin-wall tube-shaped workpiece, is specially a kind of digital control lathe clamper of thin-wall tube-shaped workpiece.

Background technology

The structure of thin-wall tube-shaped workpiece digital control lathe clamper in the past normally adopts axle to add plug to carry out clamping, though it is simple in structure, but in clamping process because the fit clearance of cylindrical work pieces and axle is wayward, can cause the circular runout of perpendicularity, cylindrical work pieces cylindrical and axis of cylindrical work pieces end face and axis overproof, thereby cause work-handling to have some setbacks.

Summary of the invention

At the problems referred to above, the utility model provides a kind of digital control lathe clamper of thin-wall tube-shaped workpiece, it can solve the employing overproof problem of the circular runout of perpendicularity, excircle of workpiece and the axis of workpiece end face and axis behind the thin-wall tube-shaped workpiece digital control lathe clamper clamping workpiece in the past, guarantee the loading and unloading of postponing of workpiece, improve working (machining) efficiency.

Its technical scheme is such, it comprises axle, it is characterized in that: it also comprises location-plate and expansion mechanism, described axle is provided with the location anchor ring with described axle one, described location-plate be set on the described axle and described location-plate and described location anchor ring by the bolt axial restraint, described expansion mechanism coaxial package is on described axle and by locking nut and described location-plate axial locking location.

It is further characterized in that:

Described expansion mechanism comprises tapered sleeve and expansion set, described tapered sleeve coaxial package is on described axle, described expansion set coaxial package is in described tapered sleeve, the axial side end face of described expansion set is located by described location-plate, described tapered sleeve outer peripheral face and described expansion set inner peripheral surface taper seat agree with, between described tapered sleeve and the described expansion set by described locking nut axial locking.

Compare with the digital control lathe clamper of thin-wall tube-shaped workpiece in the past, the beneficial effects of the utility model are: its location-plate be set in the axle periphery and with the location anchor ring of axle by the bolt axial restraint, workpiece is set in that expansion mechanism is outer, expansion mechanism is set in outside the axle during clamping workpiece, because workpiece, expansion mechanism are by location-plate, the locking of locking nut axial location, thereby it can guarantee the perpendicularity of workpiece end face and axle axis; Simultaneously, workpiece is by expansion mechanism swelling location radially, thereby effectively avoid the circular runout of excircle of workpiece and axis, wherein expansion mechanism comprises expansion set and tapered sleeve, the tapered sleeve coaxial package outside axle, the workpiece coaxial package outside expansion set, tapered sleeve outer peripheral face and expansion set inner peripheral surface taper seat agree with, expansion set and workpiece are by the location-plate axial location, thereby tapered sleeve promotes radially top tight workpiece of expansion set to location-plate one side shifting under the effect of locking nut, guarantee the radial location of workpiece.

Description of drawings

Fig. 1 is the structural representation of the digital control lathe clamper of a kind of thin-wall tube-shaped workpiece of the utility model.

The specific embodiment

Fig. 1, it comprises axle 2, location-plate 4 and expansion mechanism the utility model, axle 2 is provided with the location anchor ring 11 with axle 2 one, location-plate 4 is set on the axle 2 and location-plate 4 passes through bolt 3 axial restraints with location anchor ring 11, and the expansion mechanism coaxial package is on axle 2 and by locking nut 8, location-plate 4 axial lockings location.Expansion mechanism comprises tapered sleeve 7 and expansion set 6, tapered sleeve 7 coaxial packages are on axle 2, and expansion set 6 coaxial packages are in tapered sleeve 7, and expansion set 6 axial side end faces are by location-plate 4 location, tapered sleeve 7 outer peripheral faces and expansion set 6 inner peripheral surface taper seats agree with, between tapered sleeve 7 and the expansion set 6 by locking nut 8 axial lockings.

When the utility model uses, the end of location anchor ring 11 1 sides of axle 2 is held out against by the live center 9 on the tail stock 10 by claw 1 clamping and positioning, the end side of numerically controlled lathe, workpiece 5 is placed in outside the expansion set 6, workpiece 5, expansion set 6 are by location-plate 4 axial location, screw locking nut 8, tapered sleeve 7, expansion set 6 cooperate radially top tight workpiece 5.
