Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail with embodiment.
Such as Fig. 3, shown in 4, a kind of eccentric shaft measures frock, including standard length bar 1, vee-block 2, axial locating piece 3, rotating shaft 4, bearing block 5, bearing 7, tooling base 8, amesdial A9, dial framework 10, amesdial B11, tooling base 8 installs rotating shaft 4 by bearing block 5 and bearing 7, rotating shaft 4 is fitted with vee-block 2, and vee-block 2 front end fixed connection shaft is to locating piece 3；Vee-block 2 is placed standard length bar 1 or workpiece for measurement, tooling base 8 is installed respectively through dial framework 10 amesdial A9 and amesdial B11, and amesdial A9 and amesdial B11 is positioned at axial locating piece 3 front end, arrange in an angle between amesdial A9 and amesdial B11.Rotating shaft 4 is arranged in bearing block 5, and is supported by pair of bearings 7, sets the adjustment packing ring 6 being connected to for adjusting bearing clearance between pair of bearings 7；Bearing block 5 is arranged on tooling base 8, and is fixed by screw.Standard length bar 1 includes the first standard length bar, the second standard length bar.
As shown in Fig. 5 (a), first standard length bar is made up of positioning section C and the calibration segment D being positioned at positioning section C front end, wherein, the diameter of positioning section C is identical with the diameter of the cylindrical section B of workpiece for measurement, and the radius of calibration segment D is the center of circle distance to plane A of the cylindrical section B after the plane A level-off of workpiece for measurement.
As shown in Fig. 5 (b), second standard length bar is made up of positioning section E and the calibration segment F being positioned at positioning section E front end, the diameter of positioning section E is identical with the diameter of the cylindrical section B of workpiece for measurement, and calibration segment F is coaxial with positioning section E, and the diameter of calibration segment F is the diameter of the plane A place cylindrical section of workpiece for measurement.
Fig. 1, in 2, angle R ° is treat measuring angle, and the first step of measurement is to make measured surface level, as shown in Fig. 1 and Fig. 5 (a).Owing to final part is to position with the cylindrical section B of workpiece for measurement, so the first standard length bar is divided into two sections, first paragraph is and the positioning section C of cylindrical section B equal diameters.Second segment is concentric with positioning section C, radius be by machine rear workpiece for measurement plane A level-off after the center of circle of cylindrical section B to the distance of plane A, be called calibration segment D.When measuring, the first standard length bar is put frock, calibrates amesdial A9 with the calibration segment D of the first standard length bar 12, the peak of the calibration segment D of the first standard length bar is set to the zero point of amesdial A9.
