Guiding mechanism includes guide rod 7, spring 8 and guide holder 9, and guide holder 9 is located at the bottom of pilot hole, and guide rod 7
In the top of guide holder 9, it is fixedly connected in the upper top third hole extended in guide head 3 of guide rod 7 and with guide head 3；It leads
It is provided with the 4th hole to 7 lower end of bar, 9 upper end of guide holder is provided with the 5th hole, and the 4th hole and the 5th hole form the peace for placing spring 8
Fill hole.
It is provided with annular groove at top position on the side wall of guide rod 7 and on guide rod 7, annular groove is provided with close
Seal.
3 upper end of guide head is tip, is easily protruded into the inner hole of input shaft 10.It is provided with threaded hole in 3 outer circle of guide head,
Slot is provided on guide rod 7 on position corresponding with threaded hole, lock-screw is mounted in threaded hole and the slot, passes through lock-screw
1 guide head 3 and guide rod 7 are fixed up.
10 gear ring roll flute of input shaft processing be different from general process process, for high-precision process, so by positioning seat 5 with
The positioning surface of the input shaft 10 of axial workpiece with holes is designed as the conical surface.
Be provided with threaded hole on positioning seat 5, be correspondingly provided with through-hole in the ringfeder outer circle of cylindrical surface, positioning seat 5 with rise
Set 4 is fixedly connected by lock-screw, prevents ringfeder 4 when work from rotating relative to positioning seat 5.
Multiple stepped holes are provided on 5 end face of positioning seat, positioning seat 5 is fixedly connected with static pressure mandrel 6 by lock-screw.
In order to guarantee being evenly distributed with for expanding force, ringfeder 4 uses zero draft ringfeder, selects cylindrical surface ringfeder, and each stress is equal
It is even；Ringfeder 4 is equipped with guide angle, facilitates part automatic loading and unloading, and the static pressure by static pressure mandrel 6 is distributed, tensioner input shaft 10
Inner hole.Meanwhile guiding mechanism can be realized automatic loading/unloading, when guide rod 7 it is upper it is top be entered axis 10 compress when, spring 8
It shrinks, 4 swelling of ringfeder；After processing is completed, ringfeder 4 is shunk, and the connecting hole and ringfeder 4 of input shaft 10 there are gap, stretch by spring 8
, guide rod 7 is jacked up, input shaft 10 is ejected, quick despatch is facilitated, meets the production requirement of mass.
In processing in use, the interface that connect with lathe of 6 outer circle of static pressure mandrel is using unification φ 66mm interface, facilitate and its
He connects equipment, realizes that the fast quick change of high-precision produces.
Static pressure mandrel using import male gram Hydraulic Expanding Arbors, mandrel repetitive positioning accuracy and rotating accuracy compared with
It is high.As shown in figure 3, Hydraulic Expanding Arbors are the mandrels for being added principle to design according to hydrostatic pressure transfer principle i.e. Bath, pass through
Rotation driving bolt 61 pushes piston 62 and gasket 63 to moving inside mandrel, utilizes the pressure with mobility to transmit and is situated between
Matter, medium generally use vaseline oil, increase oil pressure in oil pocket by fabrication hole 65, the expansion of expansion wall 64 is forced to generate elasticity
Deformation carries out positioning clamping to workpiece.The mandrel has structure simple, and centering is accurate, and it is uniform to clamp appropriateness, it is easy to use and
Many advantages, such as saving non-cutting time due to clamping and feeling relieved while reaching.
Before processing, manipulator input shaft 10 be packed into this fixture, by the guiding role of guide head 3, input shaft 10 it is interior
Hole and 3 outer circle clearance fit of guide head, input shaft 10 moves from up to down, so that guide head 3 also moves downward, compressed spring 8；
Manipulator unclamps input shaft 10, top on guide rod 7 to move downward, and applies a downward power；When the 10 inner hole conical surface of input shaft
When being bonded completely with 5 conical surface of positioning seat, positioning is completed, top stopping moves downward on guide rod 7.Machine feedback static pressure mandrel 6,
By driving piston 62 and gasket 63 to moving inside static pressure mandrel 6, using the pressure transmission medium with mobility, pass through
Fabrication hole 65 increases oil pressure in oil pocket, forces the expansion of expansion wall 64 to generate flexible deformation, makes hole clip in ringfeder 4 and input shaft 10
Tightly, it completes to clamp.Machine feedback grinding carriage, grinding wheel start roll flute processing to input shaft 10.After processing is completed, machine feedback static pressure
Mandrel 6 utilizes the pressure with mobility to transmit and is situated between by driving piston 62 and gasket 63 to moving outside static pressure mandrel 6
Matter declines oil pressure by fabrication hole 65, eliminates the flexible deformation that the expansion of expansion wall 64 generates, thus ringfeder 4 and defeated
Enter the release of 10 inner hole of axis, fixture and input shaft 10 unclamp；Effect of the guide head 3 by spring 8 drives guide rod 7 to lift, and drives
Input shaft 10 moves upwards, and the 10 inner hole conical surface of input shaft and 5 conical surface of positioning seat are detached from, and manipulator grabs the part completed the process.
The gear grinding clamp for the processing axial workpiece with holes that the present invention designs, realizes high accuracy positioning clamping, can also meet
Manipulator can guarantee the high-precision requirement of roll flute process processing with automatic loading and unloading part, while have guiding mechanism, can
Realize automatic loading/unloading.Static pressure mandrel 6 uses unified size interface, fast positioning clamping, part convenient for loading and unloading.
