In the present embodiment, the size of S-shaped test specimen is 300mm × 200mm × 70mm, therefore to ensure precision and consider economic factor, almost T-stable comprehensive detection platform size range should reduce as far as possible.Supported by air-bearing between X-axis dovetail slideway and right column 3, left column 2 and marble pedestal 1, i.e. supported by air-bearing between work top, left column 2, right column 3 and crossbeam 4 collectively constitute gantry bridge architecture by the cog belt of X-direction and driven by motor, left column 2 and right column 3 support pottery crossbeam 4 and provide support force for slip crate 5 and the rod member 7 constituting Z axis, rod member 7 is made up of marble, slip crate 5 is built on pottery crossbeam 4 by air-bearing, it leans on cog belt and motor-driven along Y-motion, rod member 7 i.e. Z axis is connected with gauge head 8, by cylinder balancing gravity, the motion in Z-direction is completed by cog belt and motor.
S test specimen micro-profile detector is that equipment measured by contact pin type surface texture, builds on the marble pedestal of profile tolerance detection device, is controlled by a common control system, its structure as shown in Figure 5:
Micro-profile detector uses carry inductance type standard roughness sensor below driving box 12 to gather coarseness data (wide range carries out percent ripple data acquisition without top guide rigidity roughness sensor), the built-in line slideway of driving box 12, Precision Lead-Screw controls to measure sensor levels direction, i.e. sample direction moves, electronic column guide rail is equipped with optical-mechanical system, as the measuring basis of horizontal direction, by the position signalling of sensor acquisition vertical direction.When computer sends measuring command, driving box 12 drives inductance type transducer 13 to slide to gather the coordinate data of one group of surface profile along surface of the work, computer carry out data process.The lifting direction switch of electronic column 10 controls column control circuit and drives.
The following is parameter index and the precision index thereof of each parts in micro-profile detector of the present invention:

Application software eventually through existing control system according to recording its surface roughness of profile evaluation and percent ripple parameter (meeting the definition of GB/T3505-2009), and will can carry out the pattern analysis such as relative material ratio curve, amplitude distribution curve.
The curve form complicated due to S-shaped test specimen determines that it also can have different surface quality at diverse location, have selected representative a, b, c, d, e, f, g, 7 measured zone (as shown in Figure 6).
In measurement, difficult point concentrates on measuring point e position, if do not cut S-shaped test specimen, measuring instrument probe is difficult to probe into measurement.Although as shown in Figure 7, the micro-profile detector that the present invention uses has 90 ° of inductance type transducers rotated, solve the problem cannot measured at concave point in " S " curved surface, but rigidity during for making measuring surface form equipment work and balance ensure that percent ripple is measured and the precision of roughness concentration, and the stroke of measurement is accomplished by holding level.But the change of the complex curve of S-shaped test specimen so that measure the effect needing rotation S-shaped test specimen to can be only achieved needs.It is installed workbench so needing to have the S-shaped test specimen of the rotational freedom around y-axis direction.
In order to keep the preferable rigidity of driving box lead screw guide rails, the a length of 120mm of electronic column guide rail 11 of micro-profile detector, electronic column guide rail 11 is made up of leading screw, but after calculating rotation S-shaped test specimen, measure haul distance and at least need 210mm, so adding the linear motion degree of freedom on x direction (sample direction) on the basis of y-axis rotates original.Measuring S-shaped test specimen percent ripple and during roughness, can describing and evaluate whole curved surface in order to make sampling, up-sampling (as shown in Figure 8) so using at three kinds of different bus height, the linear motion degree of freedom being then accomplished by Y-direction.The final S-shaped test specimen needed is installed workbench as shown in Figure 9, this S-shaped test specimen be installed workbench by chassis from top to bottom, can be along X, the translation stage of Y direction translation with 360 ° of turntables rotated can be made around Y-axis and constitute, in the present embodiment: the be installed load capacity of workbench of S-shaped test specimen is 10kg；X-direction translation is 100mm；Y-direction translation is 50mm；The anglec of rotation around Y direction is 360 °；X-direction is not more than 0.05mm with the depth of parallelism of inductance type transducer running orbit.
The S-shaped test specimen workbench that is installed is built in the marble platform 9 of micro-profile detector of the present invention, and its X, Y-direction linear motion is completed with leading screw by motor, is completed by the motor that the turntable of the top is built-in around Y rotary freedom.
