Abstract
The utility model discloses a static pressure support rotary table, comprising a work bench base, wherein a center shaft is arranged on the work bench base; a rolling bearing pack is sleeved outside the center shaft; the center shaft is connected with the work bench base to from a whole body, so as to form a fixed structure; an electromagnetic suction cup is arranged on an electromagnetic suction cup connecting seat; the electromagnetic suction cup connecting seat is matched with a multi-wedge belt wheel; the electromagnetic suction cup, the electromagnetic suction cup connecting seat and the multi-wedge belt wheel form a rotary structure; and the rotary structure rotates around the center shaft through the rolling bearing pack on the center shaft. According to the static pressure support rotary table provided by the utility model, the target of adjusting and limiting the vertical floating amount of the rotary part of a work bench is achieved by adjusting a thrust ball bearing structure clearance formed by a vertical limiting ring, a ball group and the electromagnetic suction cup connecting seat; the technical requirements on a static pressure support part is properly reduced; and the static pressure support rotary table is easily adjusted.
Description
Technical field
The utility model relates to the rotary table structure on the machining tool in the mechanical processing industry, is specifically related to a kind of suitable rotary table that static pressure supports that has.
Background technology
The machining tool that has at present the rotary table structure in mechanical processing industry, its static pressure support the rotary table structure and are mostly to adopt the work table rotation part to rotate around central shaft by rolling bearing, by hydrostatic bearing floating work bench rotating part; The rolling bearing that this structure adopts infinite place on central shaft can be free to slide, and do not have vertical stopping means by the work table rotation part that hydrostatic bearing floats yet, its vertical displacement mainly determines by the overflow gap of hydrostatic bearing, thereby caused the unpredictable of its amount of floating, strengthened specification requirement and adjusting requirement to the static pressure support section simultaneously, the operation and maintenance cost is higher.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of static pressure and supports rotary table, can adjust the vertical float amount with restraint of labour platform rotating part, has suitably reduced the specification requirement to the static pressure support section, is easy to regulate.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of static pressure supports rotary table, comprises table rest, table rest is provided with central shaft, central shaft is set with the rolling bearing group outward, and central shaft and table rest connect into integral body, forms a fixed structure; Magnechuck is installed on the magnechuck Connection Block, and the magnechuck Connection Block matches with the polywedge bet wheel, and magnechuck, magnechuck Connection Block and polywedge bet wheel are formed a revolving structure; This revolving structure rotates around central shaft by the rolling bearing group on the central shaft.
The uniform static pressure back-up block group that is equipped with on the table rest forms static pressure by pressure oil and supports, and is taken turns the revolving structure of forming by magnechuck, magnechuck Connection Block and polywedge bet in order to suspension support.
Described table rest is provided with vertical spacing ring, and vertical spacing ring is connected with table rest by screw.
Vertical spacing ring and magnechuck Connection Block and ball set constitute a kind of similar thrust ball bearing structure, are used for adjusting and limiting the vertical displacement of above-described revolving structure.
A kind of static pressure that the utility model provides supports rotary table, by adjusting the formed thrust ball bearing structure interval of vertical spacing ring, ball set and magnechuck Connection Block, thereby realize the purpose of the vertical float amount of adjustment and restraint of labour platform rotating part, suitably reduced the specification requirement to the static pressure support section, and be easy to regulate.
