Description of symbols: 1- master gear, 2- axial direction positioning device, 3- screw, 4- planetary gear, the soft pawl of 5-, 6- tri-
Dog chuck.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to keep the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
The embodiments of the present invention: the structural schematic diagram of automobile-used planetary gear clamping device is as shown in Figures 1 to 3, including
Scroll chuck 6 is fixedly installed with soft pawl 5 in three card slots of scroll chuck 6, close to scroll chuck 6 on each soft pawl 5
Outer rim at be fixedly installed with planetary gear 4, the angle between three 4 center lines of planetary gear is identical, and three planetary gears 4
With the center of scroll chuck 6 away from also identical, it is axial fixed to be fixedly installed at the center of scroll chuck 6 on each soft pawl 5
Position device 2, master gear 1 are engaged with three planetary gears 4 simultaneously, and the end of master gear 1 is filled with three axially positions simultaneously
2 point contacts are set, contact surface is convenient for positioning using point contact, and convenient accurate.The axial direction positioning device 2 and master gear 1
Contact jaw is arc-shaped structure, and the end of axial direction positioning device 2 and master gear 1 is point contact.The axial direction positioning device 2 is
The integral structure being made of six square nuts and circular arc screw, thread segment is threadedly coupled with soft pawl 5 on axial direction positioning device 2.
The planetary gear 4 is fixed on soft pawl 5 by screw 3.The thickness h of the planetary gear 4 is the 1/ of 1 facewidth T of master gear
3, it is convenient for positioning and clamping, reduces and amplify clamping error because contact surface is excessive.
The modulus and pressure angle of planetary gear 4 are identical as processed gear, guarantee the teeth directional positioning accuracy of planetary gear 4,
Installation Clamping Center is calculated away from A=B=C by gathering modification coefficient, is reduced alignment error, is finally determined the tooth of planetary gear 4
Several and common normal size pays attention to the tooth top of planetary gear 4 when using form design 4 parameter of planetary gear of height change
The tooth root that processed gear need to be got out of the way prevents from interfering.The ontology of planetary gear 4 uses gear hobbing+carburizing and quenching+gear-grinding process, protects
The machining accuracy for demonstrate,proving planetary gear 4, when size roll flute, distance over bar allowance control is within 0.01mm, convenient for the fast of planetary gear 4
Speed switching.The utility model can prevent from being processed gear in turning process in the case where chucking power is small because clamping benchmark accuracy
It is not high and loose or dislocation occurs, and not directly by the end face of processed gear by putting down on soft pawl, also can effectively avoid by
Being jumped due to the teeth directional, gear ring and end face that end face contact area is big, injustice is depend on to influence to be processed gear when processing gear clamping
It is dynamic.Secondly, the product processing that the utility model can be used for needing to keep the accuracy of gear to require in grinding machine and lathe.
Working principle of the utility model is: three soft pawls 5 to be packed into three card slots of scroll chuck 6 first, and will be axial
Positioning device 2 is packed on soft pawl 5, then the end face of light vehicle axial direction positioning device 2, makes the arc point of three axial direction positioning devices 2
In the same plane, then by three planetary gears 4 bolt 3 it is fixed on soft pawl 5, the key of scroll chuck 6 is rotated, by three-jaw
The clamping stroke of chuck 6 amplifies, and is at this time fitted into master gear 1 in the tooth form of three planetary gears 4, the end face of master gear 1
By putting down on three axial direction positioning devices 2, three planetary gears 4 on soft pawl 5 are tightly packed in the key lock of scroll chuck 6, are led to
It crosses three planetary gears 4 and clamps master gear 1, the chucking power of master gear 1 decomposes to three uniformly distributed planetary gears 4 at this time
On, screwing bolts 3 successively clamp planetary gear 4, and the inner hole of calibration standard gear 1 and end face run-out are less than 0.005mm, then
Master gear 1 to be removed, changes processed gear by repeatedly clamping by flat, check is processed gear face bounce and is less than 0.01mm,
Tooling, which has adjusted to finish, at this time can carry out vehicle hole machined.
In the above method, the bolt 3 uses the cooperation of small―gap suture with the inner hole of planetary gear 4, when in planetary gear 4
When a certain tooth damage failure, bolt 3 is unclamped, revolving planet gear 4, another toothholder changed on 4 circumference of planetary gear is held processed
Gear.
For modulus, pressure angle, the identical gear of helical angle, the same planetary gear clamping device can be used, for mould
The different gear of number, pressure angle, helical angle has been loaded with the planet tooth regulated on soft pawl 5 as long as preparing different soft pawls 5
Clamping device is taken turns, the switching of different product processing can be carried out by dismantling different soft pawls 5, it is convenient and efficient.
