Abstract
The invention relates to a coordinate return-to-zero display system of a three-coordinate measuring machine, which comprises a coordinate display unit, a computing unit, an interface unit, a positioning coordinate memory unit, a coordinate counter, coordinate axes (X, Y and Z) of the three-coordinate measuring machine, a length displacement sensor (X, Y and Z) and control software. The computing unit acquires positioning coordinate values (X0, Y0 and Z0) by the interface unit, wherein, the positioning coordinate values (X0, Y0 and Z0) are transmitted by an external device or an executive program and are stored in the positioning coordinate memory unit; when the coordinate axes of the three-coordinate measuring machine move, a displacement electrical signal generated by the length displacement sensor of the coordinate axis is transmitted to the coordinate counter which is used for recording the displacement of the coordinate axes of the three-coordinate measuring machine; the computing unit reads the values (X, Y and Z) in the coordinate counter and the values (X0, Y0 and Z0) in the positioning coordinate memory unit at regular time by the interface unit and then carries out subtraction calculation; and the calculation results (X-X0, Y-Y0 and Z-Z0) are transmitted to the coordinate display unit through the interface unit.
Description
Technical field
The present invention relates to the numerical value display mode of three coordinate measuring machine manually-operated coordinate axis elements of a fix digital display.
Background technology
In the prior art, when manually-operated three coordinate measuring machine coordinate axis positioning trip, the current coordinate values of the direct displaing coordinate axle of coordinate digital display.
The problem that prior art exists is: use the prior art scheme, when the manually-operated three coordinate measuring machine carried out the coordinate setting operation, operating personnel need write down elements of a fix value (X
0, Y
0, Z
0), and the numerical value (X, Y, Z) and the elements of a fix value (X of observation coordinate digital display are wanted the time in operation
0, Y
0, Z
0) make comparisons, until both unanimities, promptly finishing the one-time positioning operation, operating personnel take great energy very much, and when positioning action data amount was big, the easy fatigue of operating personnel was made mistakes, and work efficiency is low.
Summary of the invention
The present invention is for three coordinate measuring machine provides a kind of coordinate return-to-zero display system, in the time of can solving the manually-operated three coordinate measuring machine and carry out the coordinate setting operation, and the problem that operating personnel take great energy, fatigue is made mistakes, work efficiency is low easily.
For achieving the above object, the technical solution used in the present invention is: a kind of three coordinate measuring machine return-to-zero display system, comprise computing unit, the interface unit that is electrically connected with described computing unit, the coordinate display unit that is electrically connected with described interface unit, the elements of a fix memory that is electrically connected with described interface unit, the coordinate counter that is electrically connected with described interface unit, the length displacement sensor that is electrically connected with described coordinate counter, with the three coordinate measuring machine coordinate axis of described length displacement sensor mechanical connection, it also comprises Control Software, the external unit that is electrically connected with described interface unit.The numerical value that described coordinate display unit shows is the difference of described elements of a fix memory numerical value and described coordinate counter numerical value.
Because the utilization of technique scheme, the present invention compared with prior art, the beneficial effect that it produces is: when the manually-operated three coordinate measuring machine carries out the coordinate setting operation, because elements of a fix value has been stored in the elements of a fix memory, and the numerical value that the coordinate display unit shows is the difference of elements of a fix value and the current coordinate figure of three coordinate measuring machine coordinate axis (coordinate counter numerical value), therefore, when operating, the operator needn't write down elements of a fix value and observation coordinate display unit numerical value compares with it, only need operate machines and make the coordinate display unit show that numerical value is zero, promptly finish three coordinate measuring machine coordinate setting operation No. one time, the operator can be sparing of one's energy like this, increase work efficiency, the more important thing is and avoid the positioning action mistake.
