Description
Technical field
The present invention relates to the processing in Gear Processing field, specially helical gear.
Background technology
Helical gear has good, the little advantage of stable drive, noise of engagement property.And, its registration is big, reduces the load of each pair gear, improves the bearing capacity of gear.And it is few not produce the minimum teeth number that root cuts.Because its field of conjugate action is by little size, steadily, impact is little, and noise is little for engagement；Therefore there is big bearing capacity, it is possible to increase gear life and stationarity；And small volume.Helical gear drive is meshed by two helical gears and forms.Purposes is the motion between the crossed axis of transmission space two.But, the making trouble of helical gear, and be difficult to ensure the teeth groove accuracy of form and position of processing.
In particular, in some concrete application fields, such as flexible material（As plastics）Processing, the requirement that traditional intermetallic composite coating mode will be difficult to meet reduces cost and improve process velocity and precision.
Content of the invention
The invention aims to providing a kind of processing mode of helical gear, it has the advantages that single succinct, the teeth groove high precision of processing of process equipment.Further, it is possible to meet in some flexible materials for processing cost（Especially tooling cost）The requirement reducing.
According to aspects of the present invention, by motor-driven helical gear organisation of working, for using when processing blank, it includes one kind：Pedestal、Rotatable inner thread piece、External thread piece and columned Workpiece carrier part，Wherein，Rotatable inner thread piece includes cylindrical portion and lower chambers portion，Described lower chambers portion can be rotated with pedestal circumference by bearing arrangement and axial restraint ground is connected，External thread piece is cylindrical shape，External screw thread is provided with its outer circumference surface engage with the female thread in described upper cylindrical portion，In lower chambers portion, the upside in pedestal is provided with motor，Motor is connected with the lower end of first axle，Described first axle has been fixedly mounted the first gear wheel and the first little gear from bottom to up successively，The inside circumference face in described lower chambers portion is fixedly installed ring gear，First gear wheel is engaged with described ring gear，Motor is enable when rotating, to drive described rotatable inner thread piece to rotate with respect to pedestal，It is fixedly disposed the cylindric extension in the left side extending downwardly at the bottom end face left-hand portion of described external thread piece，The top of first axle is inserted in described left cylindric extension，And can rotationally coordinate with described left cylindric extension；
Described columned Workpiece carrier part is all overlapped with the axial line of external thread piece and described upper cylindrical portion, described columned Workpiece carrier part upper end is provided with blank clamping structure, lower end middle part is fixedly disposed the middle circle column extension extending downwardly, the bottom of described columned Workpiece carrier part is connected with external thread piece by lower bearing, top is passed through upper bearing (metal) and is connected with ring-type capping, described ring-type capping is fixed with external thread piece, thus, described columned Workpiece carrier part can rotate with respect to described external thread piece；Second axle is installed the middle part axial restraint of described pedestal, the lower end of described second axle is connected with described pedestal, top is inserted in described middle circle column extension, and the axial line of described second axle is overlapped with the axial line of described columned Workpiece carrier part, described second axle all can rotationally be coordinated with described pedestal and described middle circle column extension；The bottom of described second axle is provided with enlarged diameter portion, to increase the rigidity of described second axle；Position above its enlarged diameter portion for described second axle is installed with the second gear wheel and the second little gear from bottom to up successively, and the second gear wheel is engaged with the first little gear；
Described pedestal is provided with the 3rd axle on the right side of described second axle with going back axial restraint, the lower end of described 3rd axle is connected with described pedestal, top is inserted in the blind hole in the right side wall of described external thread piece so that described 3rd axle and described pedestal and described blind hole all can rotationally coordinate；The bottom of described 3rd axle is also equipped with enlarged diameter portion, to increase the rigidity of described 3rd axle；Described 3rd axle is installed with the third-largest gear and third pinion on the position above its enlarged diameter portion from bottom to up successively, and the third-largest gear is engaged with the second little gear；Third pinion is cylindrical shape；It is installed with the fourth-largest gear, the fourth-largest gear is engaged with described third pinion on the outer circumference surface of described middle circle column extension；
Thus, it is non-rotatable under described external thread piece positions while described first axle and described three axle, when described motor rotates, described upper cylindrical portion drives external thread piece can move up and down, thus driving described columned Workpiece carrier part and blank to move up and down with respect to pedestal；Meanwhile, motor can also drive described columned Workpiece carrier part and blank to rotate with respect to pedestal by described first gear wheel, the first little gear, the second gear wheel, the second little gear, the third-largest gear, third pinion and the fourth-largest gear；And then, under the shear action of cutter, spiral alveolar can be processed on blank；When described columned Workpiece carrier part and blank rise to extreme higher position, between the top of described first axle and described left cylindric extension, between the top of described second axle and described middle circle column extension, all still keep rotationally coordinating between the top of described 3rd axle and described blind hole, described the fourth-largest gear still keeps engaging with the described third pinion of cylindrical shape.
By such scheme, due to employing the transmission of the gears at different levels of the fixing number of teeth, in the case that thread pitch is certain, ensure that rotational angular velocity and the proportionate relationship rising between linear velocity are constant, therefore, which ensure that the precision of slot form during processing spiral alveolar；And, by specific structure setting, the rotation being capable of circumferential angular velocity slows down as far as possible, and that is, with respect to the linear velocity rising, rotary speed is as far as possible slow, thus meeting the shape need of helical gear.Meanwhile, the fixation using power transmission shaft, external thread sleeve being rotated, is rotated therefore, it is possible to ensure that it does not follow inner thread sleeve；And, the central axes of middle power transmission shaft and the miscellaneous part of rotation, which ensure that power transmission shaft rotation can unrelated with the rotation of plummer such that it is able to independently rotate.Stretch out structure and blind hole structure using unique, can ensure that basic fixed structure is constant while rising, thus not affecting the transmission of power transmission shaft and for fixing in the rotation of screw shell.Upward system is tightly using a motor, the two kinds of motions that can be realized as the rotation of Gear Processing is risen are driven, ensure that the proportional precision between two kinds of motions simultaneously, therefore, disclosure satisfy that the requirement of manufacturing equipment cost control, disclosure satisfy that the antagonism of the cutting force for particular process material requires simultaneously, and disclosure satisfy that the form accuracy of gear tooth slot requires, it is not affected by processing environment confusion, and the workflow management for the maintenance of process equipment, the course of processing is respectively provided with the tolerance degree increased.
