The utility model content
But the utility model purpose provides a kind of automatic aligning and transfers the circularity/cylindricity measurement worktable that inclines, and existing circularity/the cylindricity measurement worktable adjusting time is long, efficiency of measurement is low and the technical matters of difficult assurance adjusting accuracy to overcome.
Technical solution of the present utility model is:
But a kind of aligning is transferred the circularity/cylindricity measurement worktable that inclines, its special character is, comprise the pedestal that is connected with line shaft, the operating platform that is used to place measured workpiece, three bracing frames, be used to measure measured workpiece off-centre sensor, be used for the receiving sensor output signal and adjust the control computer of operating platform locus according to this; Described signal of sensor is sent into control computer; Wherein bracing frame comprises two flexible bracing frames and a fixing support rack, the upper end of described flexible bracing frame contacts with the operating platform sphere, its underpart connects Z axle linear electric motors, described flexible bracing frame drives at Z axle linear electric motors and moves up and down to adjust the length of flexible bracing frame, Z axle linear electric motors are fixed on the pedestal, described fixing support rack upper end links to each other with operating platform by the Hooke's hinge assembly, its underpart links to each other with slide block assembly, slide block assembly respectively with the X-axis linear electric motors, the Y-axis linear electric motors link to each other, described slide block assembly is at the X-axis linear electric motors, can be under the effect of Y-axis linear electric motors respectively along X, the Y direction is slided, described X-axis linear electric motors, the Y-axis linear electric motors are fixed on the pedestal.
Technique effect of the present utility model is:
1, adjustment efficient is fast.The utility model can draw the amount of exercise that needs adjustment fast by the measurement of sensor, the processing of control computer, and by X, Y, Z axle linear electric motors drive to be adjusted, can adjust automatically the mobile and θ of X, Y direction, the swing of φ direction, realized the function that the automatic aligning accent inclines, the adjustment efficient of comparing existing surveying work platform is fast, can save and measure spending, reduces cost.
2, adjust the precision height.After the measurement of the utility model by sensor signal is passed to control computer, carry out required momental adjustment by control computer control motor again, need not artificial intervention, avoided existing surveying work platform by the big technical matters of accuracy error that manually-operated brought, make easy and simple to handlely, adjust the precision height.
