Abstract
A kind of static pressure supporting rotary workbench, including table rest, table rest are provided with central shaft, and center outer shaft sleeve is equipped with rolling bearing group, and central shaft connects integral, one fixed structure of formation with table rest；Magnechuck is arranged on magnechuck connecting seat, and magnechuck connecting seat is engaged with multi-wedge belt pulley, and magnechuck, magnechuck connecting seat and multi-wedge belt pulley form a revolving structure；The revolving structure is rotated by the rolling bearing group on central shaft around central shaft.Static pressure supporting rotary workbench provided by the invention, the thrust ball bearing structure gap formed by adjusting vertical spacing ring, ball set and magnechuck connecting seat, so as to realize the purpose of the vertical float amount of adjustment and limitation work table rotation part, the appropriate technical requirements reduced to static pressure support section, and can easily be accommodated.
Description
Technical field
The present invention relates to the rotary table structure on machining tool in mechanical processing industry, and in particular to one kind is suitable to be carried
The rotary table of static pressure support.
Background technology
The machining tool of rotary table structure, its static pressure supporting rotary workbench are carried in mechanical processing industry at present
Structure is mostly to be rotated using work table rotation part by rolling bearing around central shaft, is turned round by hydrostatic bearing floating work bench
Part；Infinite place is freely slidable on center shaft for rolling bearing used by the structure, and the work floated by hydrostatic bearing
Platform rotating part is also without vertical stopping means, and its vertical displacement determines mainly by the overflow gap of hydrostatic bearing, so as to result in
Its amount of floating it is unpredictable, while increase and the technical requirements of static pressure support section and regulation required, operation and maintenance into
This is higher.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of static pressure supporting rotary workbench, can adjust and limit work
Make the vertical float amount of platform rotating part, suitably reduce the technical requirements to static pressure support section, can easily be accommodated.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of static pressure supporting rotary workbench, bag
Table rest is included, table rest is provided with central shaft, and center outer shaft sleeve is equipped with rolling bearing group, and central shaft connects with table rest
It is integral, form a fixed structure；Magnechuck is arranged on magnechuck connecting seat, magnechuck connecting seat and multi-wedge belt pulley
It is engaged, magnechuck, magnechuck connecting seat and multi-wedge belt pulley form a revolving structure；The revolving structure passes through central shaft
On rolling bearing group rotated around central shaft.
Static pressure support block group is uniformly installed, forming static pressure by pressure oil supports, to suspension support on table rest
The revolving structure being made up of magnechuck, magnechuck connecting seat and multi-wedge belt pulley.
Described table rest is provided with vertical spacing ring, and vertical spacing ring is connected by screw with table rest.
Vertical spacing ring forms a kind of similar thrust ball bearing structure with magnechuck connecting seat and ball set, for adjusting
With the vertical displacement for limiting above-described revolving structure.
A kind of static pressure supporting rotary workbench provided by the invention, inhaled by adjusting vertical spacing ring, ball set and electromagnetism
The thrust ball bearing structure gap that disk connecting seat is formed, so as to realize the vertical float of adjustment and limitation work table rotation part
The purpose of amount, the technical requirements to static pressure support section are suitably reduced, and can easily be accommodated.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings：

Embodiment
The structure of the present invention is as shown in Figure 1-2：1st, a kind of static pressure supporting rotary workbench, including table rest 1, work
Pedestal 1 is provided with central shaft 8, is set with rolling bearing group 7 outside central shaft 8, central shaft 8 and table rest 1 connect integral, shape
Into a fixed structure；Magnechuck 3 is arranged on magnechuck connecting seat 4, and magnechuck connecting seat 4 matches with multi-wedge belt pulley 6
Close, magnechuck 3, magnechuck connecting seat 4 and multi-wedge belt pulley 6 form a revolving structure；The revolving structure passes through central shaft 8
On rolling bearing group 7 rotated around central shaft 8.
Static pressure support block group 5 is uniformly installed on the table rest 1 of the present invention, forming static pressure by pressure oil 12 supports,
The revolving structure being made up of to suspension support magnechuck 3, magnechuck connecting seat 4 and multi-wedge belt pulley 6.
Table rest 1 is provided with vertical spacing ring 10, and vertical spacing ring 10 is connected by screw 11 with table rest 1, hangs down
Straight spacing ring 10 forms a kind of similar thrust ball bearing structure with magnechuck connecting seat 4 and ball set 9, for adjusting and limiting
The vertical displacement of above-described revolving structure.By adjusting vertical spacing ring 10, ball set 9 and the institute of magnechuck connecting seat 4
The similar thrust ball bearing structure gap formed, it can reach the mesh of the vertical float amount of adjustment and limitation work table rotation part
's.
