Abstract
The utility model relates to a supporting platform and solves the problems that in the prior art, the supporting platform is unstable in supporting, reproducibility of a plane position for placing articles on an operation platform is poor, precise operation is not facilitated, and a support frame is not easily leveled. The supporting platform is composed of a support frame with a three-point orthorhombic structure and comprises three support columns and a base platform for fixing the support columns. Position points where the three support columns are distributed on the base platform form a triangle, and round through holes are arranged on the support columns. Another technical scheme of an adjusting strip matched with the supporting platform solves the problems and can be used in industrial production of support frames and supporting platforms for the precise operation.
Description
Technical field
The utility model relates to a kind of support platform.
Background technique
The first epoch occur from the mankind, begin to have occurred manufacturing.Originally just make simpler instruments, up to the formation of clan's civilization, people can make the instrument of comparison elaborate.After beginning to the industrial revolution; Machinery is able to swift and violent development, and especially behind the second industrial revolution, the manufacturing flourish people of making require improving constantly of quality to life; Begun to occur the manufacturing of various mechanical devices, originally these instruments just are used for life.Up to later stage the 1950's, people begin it is applied to industrial quantification and to the raising of production design accuracy.Along with the not only development of mechanical device and perfect, in early 1960s, the word of precision type instrument begins to appear in people's the eye.From then on precision type instrument begins constantly development infiltration, like machinery, measurement, electronics, computer and automation, optical technology or the like.
The development of precision type instrument all be unable to do without precision optical machinery always; Precision optical machinery is the basis and the requisite constituent element of instruments design; And present precision type instrument is along with and development intelligent direction integrated towards the ray machine zooming; The instrument of traditional pure machinery is fewer and feweri, and intelligent and multifunctional novel instrument constantly occurs, and has shown that more people develop new demand to precision type instrument.Though miniature instrument performance that produces till now and function be very powerful all, the development of precision type instrument still be unable to do without traditional machinery, because traditional machinery still has a lot of desirable places, and like design concept, design method etc.
Along with the development of society, every profession and trade to the placement environment of the hardware facility that relates in its industry and bearing table require increasingly high, particularly to the placement of some precision type instrument.For example, at the operating table that relates to optical element work, often require its support platform to have enough smoothnesses.
Chinese patent CN101738127A discloses a kind of adiabatic supporting device; Comprise cold of having a plurality of mounting holes on it and be used to support said cold strut; Said strut comprises the top strut again, presses down strut; Cooperate with said mounting hole with a contact or the line way of contact respectively, but the supporting frame of this model utility has four supporting posts.
Chinese patent CN2574502 discloses a kind of supported at three point balance table; It comprises the supporting part of bearing table and support bearing platform; Table top three fulcrums of supporting part are by a vertically direct supporting post; Two indirectly vertically supporting posts that are connected on the oblique support beam provide, and the other end of two oblique support beams is fixed on directly vertically on the same point of supporting post, and three supporting posts of this model utility are supporting desktop simultaneously not.
Chinese patent CN201468443U desktop supporting frame; It is characterized in that: the desktop supporting frame is provided with underframe, and the quarter butt of triangular support pin is connected with underframe, and side lever is provided with the connecting sheet of band attachment hole in each triangular support pin; Fixed block passes attachment hole each triangular support pin is fixed; The upper corners of three triangular support pin is in same plane, and forms the desktop supporting surface, but supporting post is that face contacts with desktop.
But CN102102986A the utility model relates to a kind of aligning transfers the circularity/cylindricity measurement worktable that inclines, and comprises the pedestal that is connected with line shaft, the operating platform that is used to place measured workpiece, three supporting frames; Wherein supporting frame comprises two retractable support framves and a fixing support rack, and the upper end portion of retractable support frame contacts with the operating platform sphere, and the fixing support rack upper end portion links to each other with operating platform through the Hooke's hinge assembly, but supporting post is that sphere contacts with table top.
3 have the effect of confirming a plane; The supporting frame that adopts three supporting posts to constitute has the function that supported objects is fixed on a certain plane; Near but the problem below supported at three point exists: supported object center of gravity drops on the leg-of-mutton edge that three strong points constitute or departed from the triangle inner region; Supported object is turned on one's side easily, thereby has caused the object accidental injury, even can cause security incident.
The supporting frame and the support platform of existing technology report; It all is the operating table of face contact type; All can't guarantee the enough smooth of its face, in the different operation process, the plan-position reproducibility that object is placed on the operating table is bad; Be unfavorable for accurate operation, the utility model can provide a supporting frame that on a certain plane, has enough smoothnesses.
