Description
Technical field
The utility model is relevant for a kind of crossbeam, especially relevant for a kind of rhomboid crossbeam that is applied to coordinate measuring machine.
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.
As shown in Figure 1; Be the rectangle crossbeam 1 ' that uses on the existing coordinate measuring machine, it is installed in the chute 21 ' of balladeur train parts 2 ', on the chute 21 ' madial wall of balladeur train parts 2 ', is respectively equipped with top air cushion 3 ', interior air cushion 4 ', outer air cushion 5 ' and spirit pad 6 '; When this rectangle crossbeam 1 ' is connected in the balladeur train parts 2 '; Top air cushion 3 ' contacts with the upper surface of rectangle crossbeam 1 ', and interior air cushion 4 ' contacts with the medial surface of rectangle crossbeam 1 ', and outer air cushion 5 ' contacts with the lateral surface of rectangle crossbeam 1 '; Spirit pad 6 ' contacts with the bottom of rectangle crossbeam 1 ', and this spirit pad 6 ' plays stable balladeur train parts 2 '.Wherein, Top air cushion 3 ' bears the load of center of gravity power G0; There is the moment of torsion M0 of twisting forward in balladeur train parts 2 ' under the effect of the support of air cushion 3 ' and center of gravity power G0, this moment of torsion M0 can be offset by the anchorage force F0 that interior air cushion 4 ' produces, thereby makes balladeur train parts 2 ' be in stable status.
But under the situation in each air cushion is in reasonable field of load, the moment of torsion M0 that leans forward of balladeur train parts 2 ' is big more, and air cushion 4 ' just produces same big anti-anchorage force F0, goes up connection stability to keep balladeur train parts 2 ' at rectangle crossbeam 1 '.And the size of the moment of torsion M0 that leans forward depends on distance L 0 size between center of gravity power G0 and the air cushion 3 ' supporting-point.When this rectangle crossbeam 1 ' is applied on the large-sized gantry formula coordinate measuring machine; For guaranteeing that rectangle crossbeam 1 ' has enough anchorage forces; Need with the width B of rectangle crossbeam 1 ' 0 make bigger, but from technology, economic angle, it is too big that the width B 0 of rectangle crossbeam 1 ' can not be done.
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 2; ' be installed in this triangle crossbeam 1 ' ' last time, only air cushion 3 ' when the balladeur train parts 2 ' with coordinate measuring machine ' bear the load that is caused by center of gravity power G1, this moment air cushion 3 ' ' plays the effect of fulcrum.M1 is the moment that leans forward, air cushion 4 ' ' have the trend that moves upward, do not play the effect of supporting heavy mental and physical efforts G1, only add air cushion 5 ' ', just is able to overcome the moment M1 that leans forward, air cushion 4 ' ' only play the effect of " location ".This situation by as with air cushion 3 ' ' be that fulcrum forms " lever " mechanism that turns forward, by air cushion 5 ' ' pulling just is able to balance.Have this triangle crossbeam 1 ' ' coordinate measuring machine; In case interference existence such as various vibrations are arranged; On ' on balladeur train parts 2 ' ' can the anteversion and retroversion pendulum to be connected triangle crossbeam 1 ', balladeur train parts 2 ' ' can not strong fix at triangle crossbeam 1 ' ', have a strong impact on the repeatable accuracy of measurement.
In addition; When the power of this triangle crossbeam 1 ' ' also have an implicit problem: when air cushion 5 ' ' is very big; Especially with this triangle crossbeam 1 ' ' be placed on when using on the planer-type measuring machine; The power of ' and air cushion 6 ' ' to air cushion 3 ' that the triangle crossbeam 1 ' of air cushion 3 ' ' and air cushion 6 ' ' clamping place ' like same " chock ", by air cushion 5 ' ' causes is very big, diabolo crossbeam 1 ' ' and air cushion 3 ' ', air cushion 6 ' ' go up each parts power also very big; Especially air cushion 3 ' ' 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.
