Its support platform is asked to have enough smoothnesses.
Chinese patent CN101738127A discloses a kind of adiabatic supporting device, including having the cold of multiple installing hole on it
Platform and for supporting the support bar of described cold bench, described support bar includes again topmast strut, presses support bar down, connects with point respectively
Touch or linear contact lay mode coordinates with described installing hole, but the bracing frame of this invention has four support columns.
Chinese patent CN2574502 discloses a kind of three point supporting balance table, and it includes plummer and support bearing platform
Support section, table top three fulcrum of support section is by a support column the most direct, between two are connected on skewed horizontal load beam
Connecing vertical support column to provide, the other end of two skewed horizontal load beams is fixed in the same point of the most vertically support column, this invention
Supporting desktop during three support column differences.
Chinese patent CN201468443U table top supporter, it is characterised in that: table top supporter is provided with underframe, triangle
Shape is propped up the quarter butt of spike and is connected with underframe, and in each triangular support foot, side lever is provided with the connection sheet of band connecting hole, fixing
Each triangular support foot is fixed by part through connecting hole, and the upper corners of three triangular support feet is in same plane, and is formed
Desktop support face, but support column is that face contacts with desktop.
CN102102986A the present invention relates to a kind of adjusting center and adjusts the circularity/cylindricity measurement workbench inclined, including with dynamic
Pedestal that power axle is connected, for placing the operating platform of measured workpiece, three bracing frames；Wherein bracing frame includes two flexible
Support and a fixing support rack, the upper end of retractable support frame and operating platform sphere-contact, fixing support rack upper end leads to
Cross Hooke's hinge assembly to be connected with operating platform, but support column and table top are sphere-contact.
3 have the effect determining a plane, and the bracing frame using three support columns to constitute has supported objects
It is fixed on the function of a certain plane, but supported at three point exists problem below: when the object center of gravity supported falls three supports
Putting the adjacent edges of the triangle constituted or deviate from triangle interior region, the object supported is susceptible to rollover, from
And cause object accidental injury, even can cause security incident.
The bracing frame of prior art report and support platform, be all the operating board of face contact type, all cannot ensure its face
The most smooth, in different operating process, the plan-position repeatability that on operating board, object is placed is bad, is unfavorable for precision
Operation, the present invention provides a bracing frame on a certain plane with enough smoothnesses.
Summary of the invention
The technical problem to be solved is bracing frame support instability present in prior art, the thing supported
The problem that body is susceptible to rollover, it is provided that a kind of new bracing frame with the auxiliary strong point, this bracing frame has supporting & stablizing,
Advantage.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows: a kind of support with the auxiliary strong point
Frame, it includes three hard spot support columns, a soft spots support column and the base station of fixing support column, it is characterised in that: three are hard
Point support column is distributed in base station position point and constitutes a triangle, and soft spots support column point is in outside described triangle
Region, portion, the support zone of described support column is curved-surface structure or pyramidal structure.
In technique scheme, preferred technical scheme is three support column position point line form right angle triangles
Shape, the support zone curved-surface structure of described support column is spherical structure.Three support column position point line composition isosceles are straight
