Description
Technical field
The utility model is related to a kind of rolling element structure, the rolling element structure of specifically a kind of Horizontal machining center column.
Background technology
The hard rail mounting means intensity of Horizontal machining center column is high, and rigidity is good, is adapted to heavy cut, but hard rail produces week
Phase is long, and process technology difficulty is high.Hard rail frictional force is big, and dynamic response is poor, and lubricating requirement is high, after long-time use, easily causes
Abrasion, and after hard rail abrasion, the cost of recovery is larger.In addition, the required precision that hard rail is installed to filler rod is high, it is necessary to scrape repeatedly
Grind, human cost is high.Because horizontal machining centre spindle box is suspended from front of column, and column center of gravity deviation front side itself, cause
Column is uneven to the pressure of bed piece, causes the frictional force between column and bed piece uneven, after a period of time,
It is frequently found to cause major axis horizontal precision to change because column front end modeling surface wear is serious, causes horizontal Machining centers machining accuracy
It is deteriorated.
The content of the invention
Technical problem to be solved in the utility model is：There is provided in a kind of horizontal processing in view of the shortcomings of the prior art
The rolling element structure of heart column.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of rolling of Horizontal machining center column
Kinetoplast structure, including the rolling element on front side of column lower end is fixedly mounted on, described column is arranged on bed piece, described
The lower end of column is provided with modeling face, and the upper end of described bed piece is provided with steel guide rail, under the roller of described rolling element
End face is located at the lower section of the lower surface in described modeling face, and described rolling element is pressed against on described steel guide rail.
The rolling element structure of Horizontal machining center column disclosed in the utility model, is a kind of compound guide rail shape of skid
Formula, its is simple in construction, be easily assembled.After column is assembled on bed piece, the rolling element meeting of column lower end and bed piece
On steel guide rail directly contact, the roller compressive deformation of rolling element, the modeling face of column with bed piece steel guide rail slide matches somebody with somebody
Close.The roller compressive deformation of rolling element, column imposes a upward active force, can partial offset column front end weight, put down
The weight of weighing apparatus column front and back end, makes the pressure for moulding the steel guide rail on bed piece on column uniform, so that modeling face institute
It is uniform by frictional force, the abrasion on front side of modeling face is effectively reduced, improves the static state and dynamic accuracy of horizontal Machining centers Z axis, it is ensured that
The machining accuracy of horizontal Machining centers.
Adjusting pad is provided between described rolling element and described column, described adjusting pad is fixed on described column
On, described rolling element is fixed on described adjusting pad.After the completion of column is assembled on bed piece, when needing Adjustment precision
When, adjusting pad need to be only pulled down with being milled to required thickness, then the adjusting pad after match grinding is arranged on column again, and column is filled
Fit on bed piece, it is simple to operate.Change the thickness of adjusting pad by match grinding, thus change the position of rolling element,
So as to adjust the distance between the lower surface of the lower surface of the roller of rolling element with moulding face, column assembly precision is adjusted.
The lower end of described column offers the oil filler point communicated with described rolling element.Can be to rolling element by oil filler point
Lubricating oil is conveyed, is easy to further reduce friction.
The quantity of described rolling element is two, and the rolling element described in two is symmetrically and fixedly mounted to described column lower end
Front side, be conducive to being better balanced the weight of column front and back end.
Compared with prior art, the utility model has the advantage of：Horizontal machining center column disclosed in the utility model
Rolling element structure, be a kind of compound guide rail form of skid, its is simple in construction, be easily assembled.The rolling element structure utilizes rolling
The deformation of the roller of kinetoplast balances the weight of column front and back end, changes the unequal phenomenon of weight of column front and back end, makes column
On modeling face and bed piece on steel guide rail uniform stressed, even wearing after making in face of modeling can keep the peace of column for a long time
Fill precision, it is ensured that the machining accuracy of horizontal Machining centers.
