Roundness/cylindricality measurement workbench capable of automatically regulating center and inclination

Abstract

The invention relates to a roundness/cylindricality measurement workbench capable of automatically regulating center and inclination, which comprises a pedestal fixedly connected with a power shaft, an operating platform for placing a measured workpiece, three support frames, a sensor for measuring the eccentricity of the measured workpiece, and a control computer for receiving an output signal of the sensor and regulating the space position of the operating platform. The output signal of the sensor is transmitted to the control computer; the support frames comprise two telescopic support frames and a fixed support frame, the upper ends of the telescopic support frames are in spherical contact with the operating platform, the lower parts of the telescopic support frames are connected with a Z-axis linear motor, the Z-axis linear motor is fixed on the pedestal, the upper end of the fixed support frame is connected with the operating platform through a Hooke hinge assembly, and the lower part of the fixed support frame is connected with a sliding block assembly; the sliding block assembly is connected with an X-axis linear motor and a Y-axis linear motor respectively; and the X-axis linear motor and the Y-axis linear motor are fixed on the pedestal. The workbench has high regulating efficiency.

Description

Technical field [0001] The invention relates to a measuring workbench with adjustable center and tilt, in particular to a roundness / cylindricity measuring workbench with automatic center adjustment and tilt. Background technique [0002] In the roundness / cylindricity measurement, the structure of the measuring instrument is a polar coordinate method that combines a precision turntable and a precision rail pair. The centering and tilting table is installed on the precision turntable, and then the workpiece to be tested is placed on the centering and tilting table. The centering and tilting worktable can move horizontally in the X and Y directions to adjust the eccentricity. It can also be tilted at two angles θ and φ to adjust the direction of the workpiece axis line to be consistent with the turntable axis line (θ , Φ are the angles between X, Y and the axis of the turntable). By adjusting the worktable, the slewing center of the worktable is consistent with the slewing center ...
