Abstract
The utility model relates to a kind of auxiliary mould of lathe in machining axial workpiece, the auxiliary mould includes collet and installing arm, and installing arm with the knife bar of numerically controlled lathe for being fixedly connected；Collet is plate, and plate is equipped with open slot, spring chuck is provided at left and right sides of open slot；Each spring chuck includes the first clamp arm and the second clamp arm, and one end of the first clamp arm and the second clamp arm passes through pin shaft and is rotatably mounted on plate.The utility model is by using self-centering follow-rest component, part processing rigidity can be increased, with heart function is made by oneself, cutting bring vibration is reduced when playing Auxiliary support processing to part with four bearings, so as to effectively improve the processing quality and efficiency of stock.When processing, the single-piece work time is only original 30%, greatly improves processing efficiency, and surface roughness can be reduced to Ra1.6 from original Ra12.5, processing quality greatly improved, therefore have larger practical application value.
Description
Technical field
The invention belongs to field of machining, and in particular to a kind of auxiliary mould of lathe in machining axial workpiece, with
Cutter feed motion simultaneously realizes the processing self-centering follow-rest component of elongate rod by arriving part position under the opening of supporting plate.
Background technique
Elongate rod part generally appears in machine components, when processing, due to the big part poor rigidity of axial length, processes matter
Amount efficiency is very low, especially processes the elongate rod part of 1:10 or more at present, seismism occurs in stock processing, we
Method solves a kind of suitable auxiliary support apparatus in lathe in machining long rod part.
Summary of the invention
The purpose of the present invention: providing that a kind of numerical control is automobile-used to follow knife rest to replace, processing elongate rod can it is self-centering with
Cutter holder assembly, support when increasing part processing reduce vibration with four bearing holding parts, improve processing long shaft part
Processing quality and efficiency.
Technical solution of the present invention: a kind of auxiliary mould of lathe in machining axial workpiece, the auxiliary mould include
Collet and installing arm, installing arm with the knife bar of numerically controlled lathe for being fixedly connected；Collet is plate, and plate is equipped with open slot,
Spring chuck is provided at left and right sides of open slot；The width of open slot is greater than the diameter of processed axial workpiece；
Each spring chuck includes the first clamp arm and the second clamp arm, and one end of the first clamp arm and the second clamp arm passes through pin
Axis is rotatably mounted on plate, and is provided with spring between the first clamp arm and the second clamp arm, so that the first clamp arm and second
Clamp arm is mutually drawn close under spring force, and the other end of the first clamp arm and the second clamp arm is provided with idler wheel；First clamp arm
Brachium with the second clamp arm is greater than the pin shaft to the distance of opening groove sidewall.
Further, the width of the open slot is 10~30mm
Further, the spring is torsion-bar spring or leaf spring.
Further, the plate is equipped with cover or baffle, the cover or baffle be located at numerically controlled lathe cutter head and plate it
Between, the clast for stopping processing to generate.
The utility model has the advantages that the present invention can increase part processing rigidity, have and make by oneself by using self-centering follow-rest component
Heart function reduces cutting bring vibration, so as to effectively improve when playing Auxiliary support processing to part with four bearings
The processing quality and efficiency of stock.When processing, the single-piece work time is only original 30%, greatly improves processing efficiency,
And surface roughness can be reduced to Ra1.6 from original Ra12.5, processing quality greatly improved, therefore have larger reality
Border application value.
Detailed description of the invention
This structure is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the clamping schematic diagram of this tooling；
Fig. 2 is this tooling not according to the schematic diagram of axial workpiece；
Fig. 3 is the clamping side view of the state of this tooling.
Wherein: 1- installing arm, 2- collet, 3- axial workpiece, 4- open slot, the first clamp arm of 5-, the second clamp arm of 6-, 7- pin
Axis, 8- idler wheel.
Specific embodiment
In Fig. 1 and 2 embodiment, a kind of auxiliary mould of lathe in machining axial workpiece, the auxiliary mould includes
Collet and installing arm, installing arm with the knife bar of numerically controlled lathe for being fixedly connected；Collet is plate, and plate is equipped with open slot,
Spring chuck is provided at left and right sides of open slot；The width of open slot is greater than the diameter of processed axial workpiece；
Each spring chuck includes the first clamp arm and the second clamp arm, and one end of the first clamp arm and the second clamp arm passes through pin
Axis is rotatably mounted on plate, and is provided with spring between the first clamp arm and the second clamp arm, so that the first clamp arm and second
Clamp arm is mutually drawn close under spring force, and the other end of the first clamp arm and the second clamp arm is provided with idler wheel；First clamp arm
Brachium with the second clamp arm is greater than the pin shaft to the distance of opening groove sidewall.
Further, the width of the open slot is 10~30mm
Further, the spring is torsion-bar spring or leaf spring.
Further, the plate is equipped with cover or baffle, the cover or baffle be located at numerically controlled lathe cutter head and plate it
Between, the clast for stopping processing to generate.
