Detailed description of the invention
In the following description, for purposes of illustration, in order to provide the comprehensive understanding to one or more embodiments,
Elaborate many details.Implement it may be evident, however, that these can also be realized in the case of not having these details
Example.In other example, for the ease of describing one or more embodiments, known structure and equipment show in block form an
Go out.
Before workpiece in the turnery processing that the present invention provides, end locating method can use positioning sleeve, therefore, explanation the party
Before method, the structure to positioning sleeve illustrates.
Fig. 1 shows the structure of positioning sleeve according to embodiments of the present invention.
As it is shown in figure 1, positioning sleeve includes: sleeve 1, guide cylinder 2, spring 3 and keeper 4, spring 3, keeper 4 and lead
It is separately positioned in sleeve 1 to cylinder 2；Wherein, guide cylinder 2 is arranged on the arrival end in sleeve 1, and the diameter of guide cylinder 2 is slightly larger than
The diameter of workpiece, enables workpiece to enter in sleeve 1, and due to the effect of guide cylinder 2, the part entering sleeve 1 at sleeve 1 will not
Generation is rocked, and guide cylinder 2 is fixed with sleeve 1 by location screw 6；Spring 3 is arranged on the other end in sleeve 1；Keeper 4 wraps
Including location bar the 41, first locating flange 42 and the second locating flange 43, the first locating flange 42 is arranged on location bar 41 near leading
To one end of cylinder 2, being used for fixing spring 3, the second locating flange 43 is arranged on the position between bar 41 two ends, location, is used for and work
Part contacts, and location bar 41 and the first locating flange 42 and the second locating flange 43 are formed in one structure.
The other end (being i.e. not provided with one end of the first locating flange 42) of location bar 41 stretches out sleeve 1, and is stretching out sleeve 1
Part be provided with stop screw 5, stop screw 5 can stop location bar 41 fully enter in sleeve 1.
Fig. 2 shows the structure that positioning sleeve according to embodiments of the present invention coordinates with hydraulic chuck, position tool shanks.
As in figure 2 it is shown, workpiece 9 is pushed into guide cylinder 2 hence into sleeve 1 by position tool shanks 8, enter at workpiece 9
After one end distance of sleeve 1, contact with the second locating flange 43, along with going deep into of workpiece 9, start extrusion spring 3, determining work
Part 9 arrives specific bit and postpones, and is fixed the position of workpiece 9 by hydraulic chuck 7, and hydraulic chuck 7 is arranged on sleeve 1 porch
Outside.
Foregoing describe in detail the structure of positioning sleeve, and, after positioning sleeve coordinates with position tool shanks, hydraulic chuck
Structure, before the workpiece in the turnery processing that will provide the present invention below, end locating method illustrates.
Fig. 3 shows the flow process of end locating method before the workpiece in turnery processing according to embodiments of the present invention.
As it is shown on figure 3, the present invention provide turnery processing in workpiece before end locating method, including:
Step S1: put the workpiece in positioning sleeve.
This step is manual operation, puts the workpiece in positioning sleeve by hand.
Step S2: by the position tool shanks that is arranged on cutter tower, workpiece is pushed to the predetermined bit positions of positioning sleeve；Wherein,
Predetermined bit positions is determined by the length of workpiece.
Predetermined bit positions is the length that workpiece enters positioning sleeve, reserves how many surplus for processing.Such as: workpiece
A length of 350mm, and a length of 100mm at processed position, then the length stretching out positioning sleeve controls at about 140mm.
In the present invention, cutter tower is by programme controlled, after startup program, can automatically control the movement of cutter tower, thus carry
Dynamic position tool shanks moves, and workpiece pushes to the predetermined bit positions of positioning sleeve.
Step S3: after the predetermined bit positions that workpiece pushes to positioning sleeve, clamps workpiece by hydraulic chuck, will simultaneously
Position tool shanks and cutter tower are retracted into the mechanical zero position of lathe, and are rotated by cutter tower to thread rolling wheel cutter spacing.
After the position of workpiece determines, use hydraulic chuck to fix workpiece, prevent workpiece vibration back and forth in positioning sleeve,
Hydraulic chuck is scroll chuck in the present invention.
Cutter tower rotation to thread rolling is taken turns cutter spacing is in order to workpiece is carried out screw thread process.
The mechanical zero that cutter tower is retracted into lathe is that cutter tower is every in order to prevent from accidentally injuring workpiece during rotating cutter spacing
During secondary rotation cutter spacing, need be retracted into the mechanical zero of lathe or formulate the position of coordinate points, carry out swivel knife bit manipulation, not
In the case of getting to workpiece, the position that can be retracted into formulation coordinate points carries out swivel knife bit manipulation.
Step S4: by the position of the thread rolling wheel cutter spacing feed of cutter tower to workpiece screw thread to be processed.
In step S4, the operation of cutter tower feed is also by procedure auto-control.
Step S5: hydraulic chuck rotational workpieces, meanwhile, cutter tower moves along a straight line to hydraulic chuck, screw thread to be processed to workpiece
Position carry out screw thread process.
Cutter tower, within the time period of processing screw thread, can only move linearly to the direction of hydraulic chuck, in other times section
Can move freely.
If workpiece exists multiple Working position, then, after cutter tower processing one completes a position, it is retracted into lathe
Cutter spacing required for mechanical zero position rotation, then, the next Working position of feed to next workpiece carries out screw thread and adds
Work, until completing the screw thread process of all positions of workpiece.
If workpiece is longer, centre bore can be increased in a program and be automatically positioned the stability ensureing workpiece size.
Step S6: after completing the screw thread process to workpiece, Jiang Daota is retracted into the mechanical zero position of lathe, stops
The rotation of hydraulic chuck, unclamps hydraulic chuck, the workpiece after positioning sleeve automatic spring screw thread process.
When cutter tower is not with absorption surface, it is possible to stop the rotation of the main shaft of hydraulic chuck, then unclamp hydraulic chuck.
Due to workpiece extrusion spring in positioning sleeve, so after unclamping hydraulic chuck, by the bounce of spring by work
Part ejects positioning sleeve, it is achieved the function of automatic discharging.
Step S7: open the safety door of lathe, takes out the workpiece machined.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art, in the technical scope that the invention discloses, can readily occur in change or replace, should contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with scope of the claims.
