Description
Technical field
The present invention relates to lathe screw die clamp for machining field, be specifically related to a kind of elasticity Workpiece clamping head that is used for the processing of lathe screw die.
Background technology
When the shaft head of axial workpiece was divided into the screw thread than fine pitch, if adopt turning processing, cutting was with being prone to bump between cutter and the anchor clamps, and the thread surface roughness value is big, can not guarantee product quality.Thereby the processing of the screw thread of the less pitch of spindle nose part of minor axis class part, accomplish by the lathe screw die usually.At present, the lathe screw die adds man-hour, and shaft-like workpiece uses the scroll chuck clamping on lathe, because the hardness of scroll chuck is higher, workpiece machines the back surface of the work and stays catcher mark easily, and surface of the work is impaired, and then influences the surface accuracy and the workpiece outward appearance of workpiece.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, it is impaired to provide in a kind of process surface of the work to be difficult for, and then can guarantee the elasticity Workpiece clamping head that is used for the processing of lathe screw die of surface of the work precision and workpiece outward appearance.
To achieve these goals, the technical scheme of the present invention's employing is:
The said elasticity Workpiece clamping head that is used for the processing of lathe screw die comprises that the center is provided with the chuck body of through hole, and the workpiece two ends pass the centre bore of chuck body; Said chuck body one end outer surface is provided with groove; The said chuck body other end is provided with the stopper slot that cooperates back restriction workpiece axial rotation with workpiece, on workpiece, is provided with the positive stop lug boss adaptive with said stopper slot; The end that said chuck body is provided with groove is connected with the scroll chuck of lathe.
Said stopper slot is a recess step of being located at chuck body one end; The positive stop lug boss of being located on the said workpiece is stuck on the said recess step.
Said groove and said through hole connect.
Said groove is uniformly distributed on the outer surface of said chuck body.
The groove that is arranged on the said chuck body extends to chuck body one end that said stopper slot belongs to.
Said chuck body is processed by elastomeric material.
Said chuck body is made by spring steel material.
The invention has the advantages that: the said elasticity Workpiece clamping head that is used for the processing of lathe screw die, add man-hour at the lathe screw die, the chuck body is provided with groove part and is connected with three melon chucks, when three melon chucks clamp, the stressed contraction of groove, and then workpiece pressing; Because the elastic buffer effect of groove, surface of the work is not easy to stay catcher mark, and surface of the work is difficult for impaired, can guarantee surface of the work precision and outward appearance; The limited step of workpiece cooperates with the stopper slot of chuck body, and rotation causes surface abrasion to prevent workpiece from the screw die process, to take place axially, has further guaranteed surface of the work precision and appearance; The present invention simultaneously is simple in structure, easy to process; The anchor clamps volume is little, and operation is convenient, and production efficiency is high.

The specific embodiment
Contrast accompanying drawing below, through the description to optimum embodiment, specific embodiments of the invention is done further detailed explanation.
To shown in Figure 4, the said elasticity Workpiece clamping head that is used for the processing of lathe screw die comprises that the center is provided with the chuck body 1 of through hole like Fig. 1, and workpiece 4 two ends pass the centre bore of chuck body 1, and the two ends that workpiece 4 passes are the spindle nose part of lathe screw die processing; Chuck body 1 one end outer surfaces are provided with groove 3; Groove 3 parts that chuck body 1 is provided with are connected with three melon chucks, when three melon chucks clamp, and groove 3 stressed contractions; And then workpiece pressing 4; Because the elastic buffer effect of groove 3, workpiece 4 surfaces are not easy to stay catcher mark, can guarantee workpiece 4 surface accuracies and good looking appearance; Chuck body 1 other end is provided with the stopper slot 2 that cooperates back restriction workpiece 4 axial rotation with workpiece 4, on workpiece 4, is provided with the positive stop lug boss 5 adaptive with stopper slot 2; Workpiece 4 penetrates through hole and cooperates with the stopper slot 2 of chuck body 1 until the limited step 5 of workpiece 4 during clamping, and rotation causes surface abrasion to prevent workpiece 4 from the screw die process, to take place axially, guarantees workpiece 4 surface accuracies and appearance.
Chuck body 1 is processed by elastomeric material, and is preferred, and chuck body 1 is made by spring steel material.
Groove 3 connects with through hole; The elastic effect of chuck body 1 is better like this; Groove 3 is evenly distributed on the outer surface of chuck body 1, and the scroll chuck application of force is shunk part that chuck body 1 is provided with groove 3 when workpiece 4 is clamped like this, and the active force of scroll chuck can be evenly distributed on the workpiece 4, prevents that workpiece 4 surfaces are impaired; The clamping that further also can guarantee workpiece 4 is stable, and then has guaranteed the security and the working (machining) efficiency of screw die processing; Groove 4 numbers of being located on the chuck body 1 can be adjusted according to actual needs, and preferred, the groove of being located on the chuck body 14 is four; Preferably, the groove of being located on chuck body 1 other end 4 extends to chuck body 1 one ends that stopper slot 2 belongs to, and has been equivalent to prolong the length on chuck body 1 of groove 4; The elasticity of chuck body 1 is bigger like this, is more conducive to protect workpiece 4 surfaces; Simultaneously, carry out workpiece 4 other end screw die and add man-hour, can guarantee that the position that chuck body 1 is provided with groove 4 still is connected with the scroll chuck of lathe at transposing workpiece 4.
Operation principle of the present invention is: the said elasticity Workpiece clamping head that is used for the processing of lathe screw die; Add man-hour at the lathe screw die; At first workpiece 4 is packed in the centre bore of chuck body 1; The end that chuck body 1 is provided with groove 3 is packed in the scroll chuck, shrinks the part that chuck body 1 is provided with groove 3 through the scroll chuck application of force workpiece 4 is clamped, and accomplishes the screw die processing of workpiece 4 one end spindle noses part then; The screw die that carries out workpiece 4 other end spindle noses parts when needs adds man-hour, and chuck body 1 is turned around to pack in the scroll chuck, guarantees that the scroll chuck application of force shrinks the part that chuck body 1 is provided with groove 3 workpiece 4 is clamped; The said elasticity Workpiece clamping head that is used for the processing of lathe screw die; Groove 3 parts that chuck body 1 is provided with are connected with three melon chucks, when three melon chucks clamp, and groove 3 stressed contractions; And then workpiece pressing 4; Because the elastic buffer effect of groove 3, workpiece 4 surfaces are not easy to stay catcher mark, can guarantee workpiece 4 surface accuracies and good looking appearance; Simultaneously workpiece 4 penetrates through hole and cooperates with the stopper slot 2 of chuck body 1 until the limited step 5 of workpiece 4 during clamping, prevents that workpiece 4 from axial the rotation being taken place in the screw die process cause surface abrasion, further guarantees the surface of the work outward appearance; The present invention is simple in structure, and is easy to process; The anchor clamps volume is little, and operation is convenient, and production efficiency is high.
Above the present invention has been carried out exemplary description; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
