Abstract
The utility model belongs to frock clamp field, using spiral marking connection transmitting torsion there is positive and negative buckle shaft to unload power collet to the left-hand thread of force discharging function more particularly to a kind of, the mechanism includes: the connector with positive left-hand thread, in addition pulling set, washer, left-hand thread nut, penetrating, completion torque application tight with workpiece thread belt after tommy bar；Left-hand thread nut is rotate in same direction again, is axially unscrewed washer, is pulled pressure side surface between set, workpiece, screws off collet at this time and separate with workpiece.The mechanism structure is suitable for large torque between the workpiece with same type design feature and combines, and is easy to coordinative composition of equipments and control for brake, keeps safe operation reliable.
Description
Technical field
The utility model belongs to frock clamp field, and in particular to a kind of to have positive left-hand thread using spiral marking connection transmitting torsion
The left-hand thread of axial force discharging function unloads power collet.
Background technique
When in external screw thread on connecing spiral shell and shell through being screwed, while the another end for connecing spiral shell has mouth end internal screw thread, shape
For the revolving body workpieces of camber line, it is not able to satisfy 4000NM torque demand using arcwall face clamping, is often beaten when less than 2000NM
It is sliding.Therefore torque is transmitted using mouth end internal screw thread, torque demand can be reached, but connect spiral shell and the fractionation for being screwed in torsion screw plug thereon
At problem.
Utility model content
Purpose of the utility model is to solve after screw thread transmitting large torque, what torsion screw plug was threadedly coupled with workpiece
Fractionation problem proposes a kind of left-hand thread and unloads power collet, sheds axial compression power using positive left-hand thread, realizes and smoothly splits.
The purpose of this utility model is achieved through the following technical solutions.
A kind of left-hand thread unloads power collet, including connector, nut, washer, pulls set, tommy bar；It is inserted in the miner diameter end of connector
Pull set, washer penetrates tommy bar, tightens nut, large-diameter thread couples with workpiece pulls set and workpiece end face by tight, and dextrorotation rotates tommy bar
Make-up torque is completed workpiece and is combined；Continue right-handed nut, unscrews and release nut, washer, pulls set, the axial direction on workpiece end face
Pressing force, left-handed tommy bar unload collet.
The beneficial effects of the utility model
The utility model left-hand thread unloads power collet, combines suitable for large torque between the workpiece with same type design feature, easily
In coordinative composition of equipments and control for brake, keep safe operation reliable.
Detailed description of the invention
Fig. 1 is that a kind of left-hand thread of the utility model unloads the structural schematic diagram of power collet；
1- connector, 2- nut, 3- washer, 4- pull set, 5- tommy bar
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Embodiment 1
A kind of left-hand thread unloads power collet, including connector 1, nut 2, washer 3, pulls set 4, tommy bar 5；In the path of connector 1
End cap enters to pull set 4, washer 3 penetrates tommy bar 5, tightens nut 2, and large-diameter thread couples with workpiece, pulls set 4 and leans on sternly with workpiece end face,
Dextrorotation rotates 5 make-up torque of tommy bar, completes workpiece and combines；Continue right-handed nut 2, unscrew and release nut 2, washer 3, pull set 4,
Axial pressing force on workpiece end face, left-handed tommy bar 5 unload collet.
The utility model is by a kind of connector with positive left-hand thread, in addition pulling set 4, washer 3, left-hand thread nut 2, penetrating and pull
It is tight with workpiece thread belt after bar 5, it completes torque and applies；Left-hand thread nut 3 is rotate in same direction again, is axially unscrewed washer 3, is pulled set 4, workpiece
Between pressure side surface, screw off collet at this time and separated with workpiece.
