Description
Technical field
The present invention relates to a kind of clamping apparatus for gear wheel processing technical field, in particular to a kind of cycloid gear clamp for machining.
Background technique
Cycloid gear is the general designation that flank profil is various cycloids or the roller gear of its equidistant curve, preferably per a piece of all one
Sample, can be interchanged it is general, should not processing in pairs use.
Cycloid gear epicycloidal tooth and inner shaft bearing bore have phase requirements, also there is precision positioning requirement.Two epicycloidal teeth
With bearing centerline hole phase requirements within ± 0.01o, the concentricity requirement of bearing hole and epicycloidal tooth 0.005mm with
Interior, required precision is very high, is difficult to reach using common collet, and current processing mode is to be ground outer pendulum simultaneously using two one group
Line tooth guarantees phase requirements.
And epicycloidal tooth is processed by using the mode of inner shaft bearing bore positioning, if requirement on machining accuracy is 0.01mm,
Based on concentricity requirement 0.005mm, the diameter of bearing pore size distribution is A, and cycloid segment diameter of a circle is D, then fixture is concentric
Degree requires to be (A/D) * 0.005, in other words installs composite request and needs in 0.0025mm or so, and the folder of 0.0025mm or so
It is excessively high to have required precision, is not only difficult to reach, and precision is excessively high also leads to that its production cost is excessively high, the service life is too short.
Summary of the invention
It is lower for the required precision of fixture the object of the present invention is to provide a kind of cycloid gear clamp for machining.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of cycloid gear clamp for machining, including claw, for providing a placement platform to gear；Clamping jaw is placed for clamping
Gear on claw；Diaphragm is made of resilient steel material, is fixed on a shell, for installing clamping jaw and claw, and pass through
Releasing clamping is opened in shape control clamping jaw tightening clamping；Driving element is connect with diaphragm, provides deformation power to diaphragm.
So set, when in use, cycloid gear is placed on the placement platform formed on claw, then starting driving
Element, by pulling diaphragm to clamp its deformation by cycloid gear to drive clamping jaw to act.Or first start driving element, it pushes away
Diaphragm opens clamping jaw, and cycloid gear is placed on the placement platform formed on claw at this time, then controls driving element reset
Clamping can be realized in diaphragm.Aforesaid way is set since it is used by epicycloidal tooth come phase bit, positioning, this makes fixture
Required precision can reduce (D/A)2, fixture repeatable accuracy can only need to enough guarantee in 0.005mm, can meet processing substantially
It is required that.
Further preferably are as follows: be provided with the guidance deformations of structure in a ring on the diaphragm, the guidance deformations by
It is recessed inwardly to be formed backwards to one end of clamping jaw.
So set, the thickness of guidance deformations position is small, so that the main deformation when deformation occurs for diaphragm applied force
Place just in guidance deformations, DEFORMATION POINTS more concentrates, and the reduction of deformation area is more easier to control the deformation quantity of each point,
Accuracy is higher when to make clamping jaw be clamped with diaphragm deformation.
Further preferably are as follows: the edge of the diaphragm is provided with the mounting portion that thickness is greater than diaphragm.
So set, mounting portion setting can have better installation strength for connecting with shell, meanwhile, thicken setting
It also can be avoided installation site afterwards also to deform, avoid noise spot, improve precision.
Further preferably are as follows: the mounting portion is formed with step, the guidance in diaphragm on one end end face of clamping jaw
Deformations are located at the step that mounting portion is connect with diaphragm.
So set, will guide deformations that the place that stress most concentrates is arranged in, make it easier to that deformation occurs, further
Improve deformation precision.
Further preferably are as follows: the cup depth of the guidance deformations is in gradually big setting to edge direction among diaphragm.
So set, stress intensity can also change with change in depth in the place of change in depth, keep depth big
Place more concentrate.
Further preferably are as follows: recess is formed with guide margin on the mounting portion inner sidewall, and the guide margin and guidance deformations connect
It connects.
Further preferably are as follows: recess is formed with guide margin on the mounting portion inner sidewall, and the guide margin and guidance deformations connect
It connects.
So set, improving the elastic deformation ability of guidance deformations, while it can also further increase the deformation of diaphragm
Precision.
Further preferably are as follows: have arc surface between guidance deformations and the inner sidewall of mounting portion.
So set, further increasing the elastic deformation ability of guidance deformations.
Further preferably are as follows: protrusion is provided with interconnecting piece, the bottom end of the claw and clamping jaw on the end face of the diaphragm
The link slot for interconnecting piece insertion is provided on face, the end face of the interconnecting piece and the bottom of link slot push against and be arranged, and described
Gap is provided between claw and the bottom end face and diaphragm end face of clamping jaw.
So set, the setting of interconnecting piece can increase local thickness, plays the role of installing and avoid deformation, thus
By more DEFORMATION POINTSs to guidance deformations expulsion, deformation part on diaphragm is set more to collect neutralization uniformly, to further increase
Clamp accuracy.In addition, when resetting after deformation, gap between claw and the bottom end face and diaphragm end face of clamping jaw can be to avoid
Interference and collision between the two extend service life reduction noise.
Further preferably are as follows: protrusion is provided with interconnecting piece, the bottom end of the claw and clamping jaw on the end face of the diaphragm
The link slot for interconnecting piece insertion is provided on face, the end face of the bottom end face and diaphragm of the claw and clamping jaw pushes against setting,
Maximum distance between the clamping jaw bottom end face and center, less than the minimum range between guidance deformations and center.
So set, end face pushes against rear clip-claw bottom can generate prestressing force on diaphragm, increase the deformation of its contact portion
Difficulty, to improve the accuracy of clamping indirectly.
Further preferably are as follows: stroke of each claw during entire holding action on the clamping jaw is less than
0.01mm。
So set, the activity of claw itself is just seldom, error in the whole process is much smaller than
0.01mm, therefore, error are very easy to be controlled.
Further preferably are as follows: be provided with the jack of circle hole shape on the claw, be inserted in the jack and contradicted with gear
Cylindrical abut column.
So set, avoiding the influence of the tooth form on gear periphery, gear is clamped in a manner of line contact, error is reduced
To minimum degree.
Further preferably are as follows: the claw quantity on the clamping jaw is three, and is uniformly arranged around axial line.
So set, three-jaw structure setting, clamps the optimal stability of gear in diaphragm deformation process, while having more
Good clamp precision.
In conclusion the invention has the following advantages:
1, clamping is realized in the activity for driving clamping jaw subtle by way of the diaphragm deformation of rigidity, so that for fixture itself
Required precision reduces, while also having fabulous accuracy；
2, DEFORMATION POINTS is concentrated by guiding the setting of deformations, keeps deformation more controllable, finally makes the clamp precision of clamping jaw more
Increase.
