Abstract
The invention provides a pneumatic chuck for turning the end face of an extra-thick nut in a non-shutdown manner. The pneumatic chuck comprises an elastic chuck; a sliding sleeve is arranged outside the elastic chuck; a chuck fixing sleeve is arranged outside the sliding sleeve and installed on a machine tool spindle; an ejecting sleeve is arranged in the middle of the elastic chuck; a screw is arranged in the center of the ejecting sleeve and sleeved with a spring; the ejecting sleeve is connected with a cylinder connecting shaft through the screw; and the cylinder connecting shaft is connected with the sliding sleeve through a transverse pull rod. According to the pneumatic chuck for turning the end face of the extra-thick nut in the non-shutdown manner, a workpiece is not clamped by means of the axial displacement of the pneumatic chuck any more, a cylinder shaft drives the sliding sleeve to draw in and release the elastic chuck, workpiece clamping is not affected by differences of diameter tolerances, the position of the clamped workpiece does not change in the axial direction any more, a high length tolerance can be guaranteed through positioning turning, continuous feeding is performed through a rotating handle, continuous machining can be achieved in the non-shutdown manner, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of machining apparatus, the pneumatic dop of especially a kind of not parking turning spy's high nut end face.
Background technology
At present, processing some red beat profiled member in, postorder has a turning end processing, there is problems in that 1. low by engine lathe processing efficiency before improving in this part end face turning operation, as shown in Figure 1 because scroll chuck 1 clamps six aspects of workpiece 2, owing to six aspects have pattern draft, claw clamping is point cantact, workpiece 2 stretches out long, poor rigidity, and during turning, workpiece loosens and easily forges a knife; 2. tradition dop clamps as shown in Figure 2 is realize by axial displacement, the not parking processing big cylindrical of selection is realized as clamping benchmark for improving rigidity, this part is beaten in process due to variations in temperature red, after shaping, outside dimension tolerance is 0.8mm, the size of workpiece external diameter decide card head clamping after workpiece in axial change in location, when diameter is more than 0.3mm, workpiece overall length tolerance+0.3 can not position turning.
Summary of the invention
It is an object of the invention to provide the pneumatic dop of a kind of not parking turning spy's high nut end face, it is possible to increase production efficiency, eliminate and forge a knife phenomenon.
In order to solve above-mentioned technical problem, technical scheme is as follows: the pneumatic dop of not parking turning spy's high nut end face, including elastic chuck, it is characterized in that: described elastic chuck be provided externally with slip cap, slip cap be provided externally 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, screw is cased with spring, ejector sleeve is connected axle by screw and connects with cylinder, and cylinder is connected axle and is connected by drag link with slip cap.
Improvement to technique scheme: the outer face of described elastic chuck is provided with the workpiece of inwardly sinking and accommodates mouth, it is plane that workpiece accommodates the inside wall of mouth, workpiece accommodates place's wall of mouth port and is provided with a plurality of annular groove, and the wall between adjacent annular groove forms gripping point.
Beneficial effect:
The pneumatic dop of not parking turning spy's high nut end face of the present invention, pneumatic dop is no longer rely on self axial displacement clamping workpiece, 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, not parking Continuous maching can be realized, improve production efficiency.
