Description
Technical field
The utility model relates to a kind of three coordinate measuring machine.
Background technology
In mobile bridge-type three-dimensional structure, cross slide way is fixed on longitudinal sliding frame, cross slide way drive unit is in one end of cross slide way, cross slide way can have influence on precision and the travelling speed of three coordinate measuring machine in rigidity longitudinally like this, acceleration, when infeed stroke is greater than certain size, cannot guarantee measurement performance and the travelling speed of three coordinate measuring machine, acceleration, cannot promote the efficiency of measuring machine, and the reducing gear in three coordinate measuring machine in the prior art adopts gear & rack structure as drive disk assembly, because gear & rack structure exists backlass, cause the measuring accuracy of three coordinate measuring machine lower.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple to operate, and result is reasonable, and can, by the setting of back up pad and reduction gear, improve the three coordinate measuring machine of measuring accuracy to promote rigidity and the effect that reduces backlass.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of three coordinate measuring machine comprises guide rail one, balladeur train, guide rail two, back up pad and reduction gear, described balladeur train is set on guide rail one, described guide rail two is perpendicular with guide rail one, described guide rail two is fixedly connected with balladeur train, described back up pad is between guide rail one and guide rail two, and described back up pad is rigidly connected with guide rail one and balladeur train respectively, described reduction gear is installed on guide rail two, described reduction gear includes the contact roller setting gradually, mount pad, the first gear shaft and the second gear shaft, described the first gear shaft is identical with the gear structure of described the second gear shaft, the gear teeth of described the first gear shaft and described the second gear shaft are crisscross arranged, in described mount pad, be also provided with bearing, the gear teeth of described the first gear shaft and described the second gear shaft mesh with the tooth bar of guide rail two respectively.
As preferably, described the first gear shaft and the second gear shaft are coaxially plugged on mount pad.
As preferably, described reduction gear is separately connected with motor.
The beneficial effects of the utility model are: owing to being provided with guide rail one, balladeur train, guide rail two and back up pad, and described back up pad is between guide rail one and guide rail two, and be rigidly connected with guide rail one and balladeur train, make guide rail one in rigidity enhancing longitudinally, thereby reach the effect that improves measuring accuracy when longer stroke, owing to being provided with reduction gear, and described reduction gear includes the first gear shaft and the second gear shaft, by the tooth bar meshing relation of the first gear shaft and the second gear shaft and guide rail two and the gear teeth of the first gear shaft and the second gear shaft, be crisscross arranged, reach the effect that reduces backlass and improve the precision of measurement.
Accompanying drawing explanation
Fig. 1 is the planimetric map of a kind of three coordinate measuring machine of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of three coordinate measuring machine comprises guide rail 1, balladeur train 2, guide rail 23, back up pad 4 and reduction gear 5, described balladeur train 2 is set on guide rail 1, described guide rail 22 is perpendicular with guide rail 1, guide rail 1 forms an X-Y plane with guide rail 23, described guide rail 23 is fixedly connected with balladeur train 2, described back up pad 4 is between guide rail 1 and guide rail 23, and described back up pad 4 is rigidly connected with guide rail 1 and balladeur train 2 respectively, by the setting of back up pad 4, the longitudinal rigidity of guide rail 1 is strengthened, with this, improve measuring accuracy and the travelling speed of measuring machine, acceleration, described reduction gear 5 is installed on guide rail 23, described reduction gear 5 includes the contact roller 6 setting gradually, mount pad 7, the first gear shaft 8 and the second gear shaft 9, contact roller 6 is coaxially fixedly connected with the rotating shaft of the second gear shaft 9, described the first gear shaft 8 is identical with the gear structure of described the second gear shaft 9, described the first gear shaft 8 is crisscross arranged with the gear teeth of described the second gear shaft 9, by regulating contact roller 6 can regulate easily the staggered gap between the gear teeth of the first gear shaft 8 and the gear teeth of the second gear shaft 9, in described mount pad 7, be also provided with bearing 10, the rotating shaft of the first gear shaft 8 is arranged on mount pad 7 by bearing 10, described the first gear shaft 8 meshes with the tooth bar of guide rail 23 respectively with the gear teeth of described the second gear shaft 9, the mode being crisscross arranged by this tooth bar engagement and the gear teeth, effectively reduce the first gear shaft 8 and the second gear shaft 9 and the rear backlass producing of tooth bar engagement, realization reduces backlass by reduction gear, to improve the measuring accuracy of three coordinate measuring machine.
Described the first gear shaft 8 and the second gear shaft 9 are coaxially plugged on mount pad 7.
Described reduction gear 5 is separately connected with motor (not shown), as power source.
The beneficial effects of the utility model are: by owing to being provided with guide rail one, balladeur train, guide rail two and back up pad, and described back up pad is between guide rail one and guide rail two, and be rigidly connected with guide rail one and balladeur train, make guide rail one in rigidity enhancing longitudinally, thereby reach the effect that improves measuring accuracy when longer stroke, owing to being provided with reduction gear, and described reduction gear includes the first gear shaft and the second gear shaft, by the tooth bar meshing relation of the first gear shaft and the second gear shaft and guide rail two and the gear teeth of the first gear shaft and the second gear shaft, be crisscross arranged, reach the effect that reduces backlass and improve the precision of measurement.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
