To solve the above problems, a kind of measurement apparatus being modified for various dimensions measurement that the present invention is provided are by following technical essential come solve problem：A kind of measurement apparatus being modified for various dimensions measurement, base including being provided with slide rail, the slip base for being arranged on base upper surface and being engaged with the slide rail, the montant being fixed on slip base, it is sheathed on montant and the lifting unit that can be moved up and down along the length direction of montant, it is arranged on lifting unit and relative to the adjustable cross bar of lifting unit extension elongation, the either end of the cross bar is provided with measurement head, also include many pull bars, the upper end of the pull bar is fixedly connected with cross bar, the lower end of pull bar is both secured on slip base, and pull bar annular configuration is in the surrounding of montant；The material of the montant, pull bar and cross bar is identical, and is provided with temperature sensor on montant, pull bar and cross bar.
Specifically, the pull bar of setting is used to strengthen the rigidity of montant, so, montant and pull bar total material usage less than traditional using in the form of single montant when, the montant of this structure can reach the rigidity that single montant is even more than single montant with the structure type of pull bar, above montant and the structure type of pull bar are split-type design compared to traditional single montant that uses simultaneously, therefore above structure has not only gently changed the gross weight of three-dimensional measuring machine, the dismounting of three-dimensional measuring machine is caused simultaneously, carry also more light, the deformation for further reducing three-dimensional measuring machine upper arm is also helped simultaneously.
Further limited using the material identical of montant, pull bar and cross bar, it is intended under certain environment temperature, montant, pull bar and cross bar produce it is identical or relative to thermal deformation, beneficial to certainty of measurement；Temperature sensor is provided with montant, pull bar and cross bar, it is intended to the test result of measurement head is modified by the value of feedback of temperatures above sensor, to obtain more accurate three-dimensional coordinates measurement value.
Further technical scheme is：
To enable that pull bar serves the entirety of montant, the pull bar is respectively positioned on the upper end of montant with the tie point of montant.
As one kind under conditions of montant and each self-strength of pull bar is met, the implementation of montant and pull bar weight can be reduced, the montant and pull bar are tapered rod of the upper end diameter less than respective lower end diameter.
Used as the montant and the structure type of pull bar of a kind of bigger rigidity readily available under identical material usage, the montant and pull bar are hollow structure.
There is the good cross bar implementation for resisting crooked deformability, rectangle of the cross bar perpendicular to the longitudinal cross-section of its length direction in width less than height in identical material usage sheer pole as a kind of.
There is the good further implementation of cross bar for resisting crooked deformability in identical material usage sheer pole as a kind of, the cross bar is hollow stem.
The invention has the advantages that：
1, the pull bar of setting is used to strengthen the rigidity of montant, so, montant and pull bar total material usage less than traditional using in the form of single montant when, the montant of this structure can reach the rigidity that single montant is even more than single montant with the structure type of pull bar, above montant and the structure type of pull bar are split-type design compared to traditional single montant that uses simultaneously, therefore above structure has not only gently changed the gross weight of three-dimensional measuring machine, the dismounting of three-dimensional measuring machine is caused simultaneously, carry also more light, the deformation for further reducing three-dimensional measuring machine upper arm is also helped simultaneously.
2nd, further limited using the material identical of montant, pull bar and cross bar, it is intended under certain environment temperature, montant, pull bar and cross bar produce it is identical or relative to thermal deformation, beneficial to certainty of measurement；Temperature sensor is provided with montant, pull bar and cross bar, it is intended to the test result of measurement head is modified by the value of feedback of temperatures above sensor, to obtain more accurate three-dimensional coordinates measurement value.
