Abstract
The utility model provides the pneumatic dop of the special high nut end face of a kind of turning of not stopping, comprise elastic chuck, the outside of described elastic chuck is provided with slip cap, the outside of slip cap is provided with dop fixed cover, and dop fixed cover is arranged on machine tool chief axis, and the middle part of elastic chuck is provided with ejector sleeve, the center of ejector sleeve is provided with screw, on screw, cover has spring, and ejector sleeve is connected with cylinder connecting axle by screw, and cylinder connecting axle is connected by drag link with slip cap.The pneumatic dop of the special high nut end face of turning of not stopping described in the utility model, pneumatic dop no longer relies on self axial displacement clamping work pieces, cylinder axis is utilized to drive slip cap folding and unfolding spring chuck, Workpiece clamping is no longer by the difference of diameter tolerance, after clamping axially no longer there is change in location in workpiece, and location turning can ensure higher length tolerance, utilizes rotary handle friction feeding, the Continuous maching that do not stop can be realized, enhance productivity.
Description
Technical field
The utility model relates to a kind of machining apparatus, the pneumatic dop of the special high nut end face of especially a kind of turning of not stopping.
Background technology
At present, processing some red break into shaped piece in, a turning end processing is had in postorder, in this part end face turning operation, following problem is there is: 1. use engine lathe processing efficiency low, as shown in Figure 1 because of six aspects of scroll chuck 1 holding workpiece 2, because six aspects have pattern draft before improving, claw clamping is point cantact, workpiece 2 stretches out long, poor rigidity, and during turning, workpiece loosens and easily forges a knife; 2. traditional dop clamps as shown in Figure 2 is realize by axial displacement, for improve rigidity realize do not stop processing select large cylindrical as clamping benchmark, this part is beaten in process due to variations in temperature red, after being shaped, outside dimension tolerance is 0.8mm, the size of workpiece external diameter decides the change in location of the rear workpiece of dop clamping in axis, when diameter is more than 0.3mm, workpiece overall length tolerance+0.3 can not locate turning.
Summary of the invention
The purpose of this utility model is to provide the pneumatic dop of the special high nut end face of a kind of turning of not stopping, and can enhance productivity, eliminate phenomenon of forging a knife.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the pneumatic dop of the special high nut end face of turning of not stopping, comprise elastic chuck, it is characterized in that: the outside of described elastic chuck is provided with slip cap, the outside of slip cap is provided with dop fixed cover, dop fixed cover is arranged on machine tool chief axis, the middle part of elastic chuck is provided with ejector sleeve, the center of ejector sleeve is provided with screw, on screw, cover has spring, ejector sleeve is connected with cylinder connecting axle by screw, and cylinder connecting axle is connected by drag link with slip cap.
Improvement to technique scheme: the outer face of described elastic chuck is provided with the workpiece inwardly sunk and accommodates mouth, the inside wall that workpiece accommodates mouth is plane, place's wall that workpiece accommodates mouth port is provided with many annular grooves, and the wall between adjacent annular groove is formed and accommodates point.
Beneficial effect:
The pneumatic dop of the special high nut end face of turning of not stopping described in the utility model, pneumatic dop no longer relies on self axial displacement clamping work pieces, cylinder axis is utilized to drive slip cap folding and unfolding spring chuck, Workpiece clamping is no longer by the difference of diameter tolerance, after clamping axially no longer there is change in location in workpiece, and location turning can ensure higher length tolerance, utilizes rotary handle friction feeding, the Continuous maching that do not stop can be realized, enhance productivity.
