Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these examples are merely to illustrate this
It invents rather than limits the scope of the invention, after the present invention has been read, those skilled in the art are to of the invention various
The modification of equivalent form falls within the application range as defined in the appended claims.
A kind of high tolerance gear ring gear-hobbing clamp, as shown in Figure 1, main centering portion, position portion, pressing section, upper pressure
Lid fine tuning part, tensioner sliding block unclamp the composition such as part automatically.
Centering portion includes: being mainly made of centering sliding block 11, taper body 8, take-up housing 12.For precision centering high tolerance
Gear ring, centering sliding block need to be by sufficiently large tensioner amount and big radial force.Therefore using workbench oil cylinder pull down to taper body 8 uniformly to
The pulling force of lower pressure about 4.42t, by 30 ° of conical surfaces, and taper-face contact length is more than the 2/3 of part beam overall, to 11 centering sliding blocks
The radial force of pressure about 10t.Sliding block 11 feel relieved along the chute uniformly to two sides tensioner, in order to uniform to inner hole of workpiece circumferencial direction
Apply radial force, sliding block quantity is set to 16, until tensioner high tolerance inner hole of workpiece, it is ensured that workpiece is accurately felt relieved.
Position portion is mainly made of take-up housing 12, positioning disk 13, pedestal 14.For positioning workpiece, guarantee the rolling of fixture
Tooth station size constancy.
Pressing section is mainly made of briquetting 1, open washer 2, upper press cover 4, pull rod 9.Workbench oil cylinder moves down drive and draws
Bar 9 moves down, and applies downward power to open washer 2 by the briquetting 1 being attached thereto, by the transmitting of power, eventually by upper pressure
Lid compresses plane on gear ring 4.Because workbench pulling force up to several tons, can guarantee workpiece pressing positioning surface.
The multiple processing of gear ring, dimensional tolerance accumulative variation in width of the workpiece direction is big, and upper press cover 4 need to be made into floating, therefore pass through
Briquetting 1 and 9 connection screw thread of pull rod adjust 4 upper and lower position of upper press cover, and plane on compacting gear ring may be implemented, and guarantee to compress gear ring.
After the completion of gear hobbing, workpiece is taken for convenience.Workbench oil cylinder, which moves up, drives pull rod 9 to move up, and then drives and pressing sleeve 5
Connected taper body 8 moves up.The conical surface disengages at this time, and banding spring 10, which is shunk, drives centering sliding block 11 along 12 rectangle of take-up housing
It is moved in slot, disengages inner hole of workpiece.
In order to when the conical surface disengages, centering sliding block 11 can in move, so getting on the bus four on the cylindrical surface of centering sliding block 11
Group annular groove is made with four groups of cylindrical spring bandings for overcoming the frictional force of centering sliding block 11 and 12 rectangular slot of take-up housing
Sliding block of feeling relieved is interior to be moved, and then unclamps workpiece.
In order to preferably guarantee that cutting precision, fixture need to be firmly fixed on work top, therefore use 6-M16x85's
Pedestal 14 is connect by T-bolt with workbench, guarantees bonding strength.
It is provided with limit chamber on the pressing sleeve 5, fixed ring 7 is provided on the centering sliding block 11, the fixed ring 7 is located at
In limit chamber.Open washer 2 is provided between the briquetting 1 and upper press cover 4.It is provided between the pull rod 9 and positioning disk 13
Gasket 6, and the gasket 6 is between pull rod 9 and pressing sleeve 5.Limiting slot is provided on the pull rod 9, banking pin passes through positioning
Disk 13 is extend into limiting slot.
Working principle of the invention is as follows:
After clamp fixture installation accuracy is checked, it is sequentially placed into workpiece by figure, guarantees that 12 positioning surface of take-up housing is most lower with it
Work end face paste jail.Workbench oil cylinder drives pull rod 9 to move down, and the locking nut being attached thereto 3 is driven to apply downwards to pressing sleeve 5
Power, and then drive taper body 8 move down, taper body 8 move down by the conical surface uniformly to centering sliding block 11 apply radial force, centering
Sliding block 11 along rectangle sliding slot uniformly to two sides tensioner, until pre- tensioner inner hole of workpiece.Briquetting 1, open washer are installed at this time
2, upper press cover 4 manually tighten the screw thread of briquetting 1 Yu pull rod 9, guarantee that upper press cover 4 can workpiece pressing upper surface.With aftertable
Oil cylinder drives the parts such as pull rod 9 to move up again, and the screw thread about 1/4 that can be manually rotated briquetting 1 and pull rod 9 encloses, workbench oil cylinder again to
Lower tension can guarantee compress positioning surface and precisely centering inner hole of workpiece at this time.Gear hobbing completes aftertable oil cylinder and moves up drive drawing
The parts such as bar 9 move up, and drive taper body 8 to move up by pressing sleeve 5, and the conical surface disengages at this time, and banding spring 10 drives centering 11 edge of sliding block
Move in 12 rectangular slot of take-up housing, unclamp inner hole of workpiece.Open washer 2 and upper press cover 4 are removed, workpiece is at this moment further taken out, is put
Into new workpiece, continue gear hobbing process.
The centering of workpiece and positioning all apply pulling force by workbench, because the pulling force of workbench is up to several tons, completely
Certifiable workpiece is accurately felt relieved and is positioned.It is different from traditional structure, precision can more be guaranteed.Using the above structure well
Solves the problems, such as the gear hobbing process of high tolerance gear ring, worker only needs clamping workpiece, remaining is automatic processing, improves machining accuracy
And efficiency, reduce labor intensity of workers.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
