Description
Technical field
The present invention relates to the processing in Gear Processing field, specially helical gear.
Background technology
It is good that helical gear has engagement property, advantage that stable drive, noise are little.Further, its registration is big, reduces the load of every pair of 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 steadily, is impacted little by little size, engagement, noise is little；Therefore there is big bearing capacity, it is possible to increase gear life and stationarity；And volume is little.Helical gear drive is meshed by two helical gears and forms.Purposes is the motion between the crossed axis of transmission space two.But, making trouble of helical gear, and it is difficult to ensure the teeth groove accuracy of form and position of processing.
In particular, in some concrete applications, such as flexible material (such as plastics) processing, traditional intermetallic composite coating mode reduces cost by being difficult to meet and improves process velocity and the requirement of precision.
Summary of the invention
The invention aims to provide the processing mode of a kind of helical gear, it has the advantage that the single teeth groove precision succinct, processing of process equipment is high.Further, it is possible to meet the requirement reduced in some flexible materials for processing cost especially tooling cost.
nullAccording to aspects of the present invention，A kind of helical gear process equipment that can lift，For using when processing blank，Comprising: pedestal、Column、Milling head、Rotatable inner thread piece、External thread piece and columned Workpiece carrier part，Wherein，Pedestal is fixing with the lower end of column to be connected，The upper end of column is provided with lowering or hoisting gear，Lowering or hoisting gear upper end is provided with milling head，Described blank can be cut by milling head by the rotation of milling cutter，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 cylindric，It is provided with external screw thread on its outer circumference surface to engage with the female thread in described upper cylindrical portion，Pedestal is provided with cavity，Cavity has top wall，Driving motor is installed in described cavity，The lower end driving motor and the first axle connects，Described first axle is through the left-hand portion of described top wall，And on the section that described first axle is positioned at above top wall, it has been fixedly mounted the first gear wheel and the first little gear the most successively，The inside circumference face in described lower chambers portion is fixedly installed ring gear，First gear wheel engages with described ring gear，Make when driving electric machine rotation, to drive described rotatable inner thread piece to rotate relative to pedestal，The cylindric extension in the left side downwardly extended it is fixedly disposed at the bottom end face left-hand portion of described external thread piece，The top of the first axle is inserted in the cylindric extension in a described left side，And extension cylindric with a described left side can coordinate rotationally；
Described columned Workpiece carrier part all overlaps with the axial line of external thread piece and described upper cylindrical portion, its upper end is provided with blank clamping structure, middle part, lower end is fixedly disposed the middle circle column extension downwardly extended, the bottom of described columned Workpiece carrier part is connected with external thread piece by lower bearing, top is connected with ring-type capping by upper bearing (metal), described ring-type capping is fixed with external thread piece, thus, described columned Workpiece carrier part can rotate relative to described external thread piece；Second axle is installed the middle part axial restraint of described top wall, the lower end of described second axle is connected with described top wall, top is inserted in described middle circle column extension, and the axial line of described second axle overlaps with the axial line of described columned Workpiece carrier part, described second axle all can coordinate rotationally with described top wall and described middle circle column extension；Second largest gear and two pinion, second largest gear and the engagement of the first little gear it is installed with the most successively on described second axle；
Described top wall 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 top wall, top is inserted in the blind hole in the right side wall being positioned at described external thread piece so that described 3rd axle all can coordinate rotationally with described top wall and described blind hole；The third-largest gear and third pinion, the third-largest gear and two pinion engagement it is installed with the most successively on described 3rd axle；Third pinion is cylindric；Being installed with the fourth-largest gear on the outer circumference surface of described middle circle column extension, the fourth-largest gear engages with described third pinion；
Thus, under described external thread piece positions while described first axle and described 3rd axle non-rotatable, when described driving electric machine rotation, described upper cylindrical portion drives external thread piece to move up and down, thus drives described columned Workpiece carrier part and blank to move up and down relative to pedestal；Meanwhile, motor is driven described columned Workpiece carrier part and blank can also to be driven to rotate relative to pedestal by described gear；And then, under the shear action of cutter, it is possible to process spiral alveolar on blank；When described columned Workpiece carrier part and blank rise to extreme higher position, the most still keeping between the top extension cylindric with a described left side of described first axle, between the top of described second axle and described middle circle column extension, between the top of described 3rd axle and described blind hole coordinating rotationally, described the fourth-largest gear still keeps engaging with cylindric described third pinion.
Pass through such scheme, owing to have employed the transmission of the gears at different levels of the fixing number of teeth, in the case of thread pitch is certain, it is possible to ensure that the proportionate relationship between rotational angular velocity and riser speed is constant, therefore, which ensure that the precision of slot form during processing spiral alveolar；And, arranged by specific structure, it is possible to the rotation realizing circumference angular velocity slows down as far as possible, i.e. relative to the linear velocity risen, rotary speed is the slowest, thus meets the shape need of helical gear.Meanwhile, utilize that external thread sleeve rotates by power transmission shaft is fixing, therefore, it is possible to ensure that it is not followed inner thread sleeve and rotates；And, middle power transmission shaft and the central axes of the miscellaneous part of rotation, which ensure that the rotation of power transmission shaft can be unrelated with the rotation of plummer such that it is able to rotate independently.Utilize uniqueness stretches out structure and blind hole structure, it is possible to ensure that basic fixed structure is constant while rising, thus does not interferes with the transmission of power transmission shaft and for fixing in the rotation of screw shell.Upward system tightly uses a driving motor, can be realized as that Gear Processing rotates the two kinds of motions risen to be driven, ensure that the proportional precision between two kinds of motions simultaneously, therefore, disclosure satisfy that and manufacture the requirement that equipment cost controls, disclosure satisfy that the antagonism requirement of cutting force for particular process material simultaneously, and disclosure satisfy that the form accuracy requirement of gear tooth slot, it is not affected by processing environment confusion, is respectively provided with, for the maintenance of process equipment, the workflow management of the course of processing, the tolerance degree increased.
