Then the compensation is carried through so that the accuracy of the electric principal axis can be ensured. The utility model is the top grade electric principal essential equipment.
Description
Technical field:
The utility model relates to a kind of displacement measuring device, especially a kind ofly can accurately measure, compensate electric main shaft displacement, guarantees the electric main shaft absolute displacement measurement mechanism of electric main shaft precision.
Background technology:
At present, along with the electromechanical integration high speed machining develops rapidly, accurate mechanical equipments such as various grinding machines, engraving machine, numerically-controlled machine are used more and more widely, and the critical piece of these equipment has electric main shaft, by Bearing Installation on lathe.Can produce a large amount of heats because electric main shaft is on-stream, make it produce thermal deformation, directly influence the precision of electric main shaft.For avoiding the generation of this situation, the method that is adopted mainly contains two kinds:
1. with temperature control equipment within the specific limits,, can't guarantee the machining precision of product because the not displacement that produces owing to thermal deformation of energy measurement electricity main shaft can't compensate then with the control of the temperature of electric main shaft;
2. the electric main shaft displacement when measuring a plurality of temperature value by interpolation arithmetic, calculates the displacement of main shaft under different temperatures to compensate by digital control system.Though precision improves, the displacement accuracy of interpolation point can't guarantee, and all need pass through actual measurement to each lathe, and workload is bigger.
Summary of the invention:
The utility model is can accurately measure, compensate electric main shaft displacement in order to solve existing in prior technology the problems referred to above, to provide a kind of, to guarantee the electric main shaft absolute displacement measurement mechanism of electric main shaft precision.
Technical solution of the present utility model is: a kind of electric main shaft absolute displacement measurement mechanism, ring flange 1 is arranged, on ring flange 1, be fixed with measuring distance sensor 2 and gauged distance sensor 3, measuring distance sensor 2 joins with the output and the comparer of gauged distance sensor 3, and the output and the measurement mechanism of comparer join.
Be provided with screw 4 on ring flange 1, described measuring distance sensor 2 is to be provided with the support 5 that has been threaded with screw 4, and range sensor 6 is fixed on the end in the support 5.
The other end at support 5 is provided with catch 7, is equipped with trimmer 8 on the catch 7.
Be provided with screw 9 on ring flange 1, described gauged distance sensor 3 is to be provided with the support 10 that has been threaded with screw 9, is disposed with fixed thickness sensing chip 11, partition 12, range sensor 13 from outside to inside at an end of support 10.
The other end at support 10 is provided with catch 14, is equipped with trimmer 15 on the catch 14.
Be connected to temperature control equipment with described measurement mechanism.
The utlity model has advantages such as simple in structure, that measurement is accurate, the tracking reaction velocity is fast, but the absolute displacement value of continuous coverage electricity main shaft under different temperatures, measuring accuracy can reach 0.0001mm, compensates then, to guarantee electric main shaft precision, be the indispensability equipment of high-grade electric main shaft.
