Background technology
Coordinate measuring machine is the electromechanical integration measuring instrument that grows up over nearly 40 years, and development in recent years is rapider, uses more extensively, is mainly used in the manufacturing of machine manufacturing, automobile, tractor, instrument at present.
The crossbeam that uses on the existing coordinate measuring machine mainly can be divided into two types, and a kind of is the most frequently used rectangle crossbeam, and another kind is a cant beam.Cant beam is because of having center of gravity that can reduce the beam moving component and the torsional rigidity that can improve the beam moving component, and the contour structures better appearance of integral arrangement, and can save the advantages such as air cushion quantity on the air-float guide rail, and has obtained using widely.
The cant beam that uses on the existing coordinate measuring machine is mainly the triangle crossbeam; The cross section of this crossbeam is a triangle; As shown in Figure 1; When the balladeur train parts 2 ' with coordinate measuring machine are installed in 1 ' last time of this triangle crossbeam, only air cushion 3 ' bears the load that is caused by center of gravity power G1, and this moment, air cushion 3 ' played the effect of fulcrum.M1 is the moment that leans forward, and air cushion 4 ' has the trend that moves upward, and does not play the effect of supporting heavy mental and physical efforts G1, only adds air cushion 5 ', just is able to overcome the moment that leans forward, and air cushion 4 ' only plays the effect of " location ".This situation is leaned on air cushion 5 ' to hold and just is able to balance by as being that fulcrum forms " lever " mechanism that turns forward with air cushion 3 '.Coordinate measuring machine with this triangle crossbeam 1 '; In case interference existence such as various vibrations are arranged; The balladeur train parts 2 ' that are connected on the triangle crossbeam 1 ' can anteversion and retroversion be put; Balladeur train parts 2 ' can not strong fix on triangle crossbeam 1 ', under the condition that various vibrations are disturbed, can have a strong impact on the measurement repeatable accuracy of coordinate measuring machine.
In addition; This triangle crossbeam 1 ' also has an implicit problem: when the power of air cushion 5 ' is very big; Especially this triangle crossbeam 1 ' is placed on when using on the planer-type measuring machine, the triangle crossbeam 1 ' of air cushion 3 ' and air cushion 6 ' clamping place is like same " chock ", and the power to air cushion 3 ' and air cushion 6 ' that is caused by air cushion 5 ' is very big; The power that diabolo crossbeam 1 ' and air cushion 3 ', air cushion 6 ' are gone up each parts is also very big, and especially air cushion 3 ' is stressed much larger than center of gravity power G1.These all are the technical matterss that can influence the coordinate measuring machine performance.
Therefore, be necessary to provide a kind of crossbeam of novel coordinate measuring machine, overcome above-mentioned defective.
The utility model content
The purpose of the utility model provides a kind of trapezoidal crossbeam of coordinate measuring machine, and the balladeur train parts of coordinate measuring machine can firmly be connected on this trapezoidal crossbeam, and the balladeur train parts can anteversion and retroversion not put, and have effectively improved the measurement repeatable accuracy of coordinate measuring machine.
The above-mentioned purpose of the utility model can adopt following technical proposal to realize:
The utility model provides a kind of trapezoidal crossbeam of coordinate measuring machine; It is connected on the balladeur train parts of coordinate measuring machine; The cross sectional shape of the trapezoidal crossbeam of said coordinate measuring machine is an isosceles trapezoid; Said balladeur train parts are provided with a plurality of air cushions, and said air cushion is arranged on the trapezoidal side edges and base of trapezoidal crossbeam of said coordinate measuring machine, and the trapezoidal top margin of the trapezoidal crossbeam of said coordinate measuring machine and said balladeur train parts are oppositely arranged.
In preferred embodiment, the trapezoidal crossbeam of said coordinate measuring machine is connected on the said balladeur train parts horizontal by miter angle.
In preferred embodiment, be furnished with two air cushions respectively on two trapezoidal side edges of the trapezoidal crossbeam of said coordinate measuring machine, the base of the trapezoidal crossbeam of said coordinate measuring machine is furnished with an air cushion respectively near two bottom.
The characteristics and the advantage of the trapezoidal crossbeam of the coordinate measuring machine of the utility model are: the trapezoidal crossbeam of this coordinate measuring machine is with after the balladeur train parts link to each other; The effect that the air cushion that leans with trapezoidal crossbeam upper side on the balladeur train parts bears gravity; Form under the condition of " fulcrum " at this air cushion and with the contiguous air cushion that is arranged on the trapezoidal crossbeam base of this air cushion; The balladeur train parts form, and the moment that leans forward is offset to supporting power by the level of the air cushion that leans with trapezoidal crossbeam bottom side, and another air cushion that is resisted against on the trapezoidal crossbeam base plays stabilization.Also promptly, the moment that leans forward is big more, and it is firm more that the balladeur train parts connect on trapezoidal crossbeam, and the balladeur train parts pendulum that on trapezoidal crossbeam, can not incline has effectively guaranteed the measurement repeatable accuracy of coordinate measuring machine.
