Abstract

The utility model provides a lathing fixture structure of thin-wall barrel-shaped parts. The lathing fixture structure of the thin-wall barrel-shaped parts can reliably clamp a workpiece and solve the problem in the prior clamping mode that a workpiece is inconvenient to clamp and disassemble, comprises a mandrel clamped by a lathe clamping disc, and is characterized by further comprising a workpiece tensioning mechanism installed on the mandrel, the workpiece to be machined is installed on the workpiece tensioning mechanism and is positioned by the workpiece tensioning mechanism in the radial direction, and both the workpiece to be machined and the workpiece tensioning mechanism are positioned by the positioning ring surface of the mandrel in the axial direction.

Description

A kind of Vehicle Processing clamp structure of thin-walled class cylindrical part

Technical field

The utility model relates to the Vehicle Processing frock field of thin-walled class cylindrical part, is specially a kind of Vehicle Processing clamp structure of thin-walled class cylindrical part.

Background technology

Many axle clamping or scroll chuck clampings of directly adopting during general thin-walled class cylindrical part Vehicle Processing, its clamping is unreliable, and also needs centering behind the clamping, and clamping workpiece, dismounting are inconvenient, and working (machining) efficiency is low.

Summary of the invention

At the problems referred to above, the utility model provides a kind of Vehicle Processing clamp structure of thin-walled class cylindrical part, and it can carry out reliable clamping to workpiece, and solves clamping workpiece, the inconvenient problem of dismounting that existing installation way exists.

Its technical scheme is such, it comprises axle, described axle is by the lathe chuck clamping, it is characterized in that: it also comprises the workpiece expansion mechanism, described workpiece expansion mechanism is installed on the described axle, workpiece to be processed is installed on described workpiece expansion mechanism and by the radial location of described workpiece expansion mechanism, and described workpiece to be processed, workpiece expansion mechanism are axially by the anchor ring location, location of described axle.

It is further characterized in that:

Described expansion mechanism comprises expansion set and pull bar;

Described expansion set comprises axial mounting portion and radially swelling part, the inner peripheral surface of described axial mounting portion is inner peripheral surface, described expansion set is by the inner peripheral surface of described axial mounting portion and the cylindrical clamping of described axle, the inner peripheral surface of described radially swelling part is internal conical surface, described radially swelling part is along circumferentially evenly having breach, and described workpiece to be processed is set in the cylindrical of described expansion set;

Described expansion set, described workpiece to be processed by the locating ring over glaze of described axle to the location;

Described pull bar passes axle, chuck, spindle stock successively along lathe spindle direction right-to-left, described pull bar right-hand member is provided with outer conical surface, the inner peripheral surface of described outer conical surface and described expansion set agrees with, and described pull bar left part is by plug, nut axial locking.

Adopt its beneficial effect of the utility model clamp structure to be: its expansion mechanism is installed on axle, by axle expansion mechanism, workpiece are carried out axial location, by expansion mechanism workpiece is carried out radial location simultaneously, thereby realize the reliable clamping to workpiece, with the reliable clamping of workpiece; Wherein expansion mechanism comprises expansion set and pull bar, expansion set is connected in the axle cylindrical, and an end male cone (strobilus masculinus) of the interior Zhou Xianyu pull bar of expansion set agrees with, only workpiece need be placed in the expansion set periphery during clamping, strain then pull bar, since the outer conical surface of expansion set internal conical surface and pull bar one end agree with, thereby expansion set is radially strutted the stretching workpiece by pull bar, the nut check with pull bar the other end gets final product again, its clamping is convenient, improves clamping workpiece efficient greatly.
