Embodiment
Enumerating a specific embodiment below in conjunction with accompanying drawing further explains the invention.
The invention is a kind of device of measuring tooth cover face runout, as shown in Figure 1, present embodiment comprises main body base 1, column 2, support arm 3, measures main shaft, master gear 4, measuring instrument, 2 on main body base 1 and column are connected by the horizontally-guided device, column 2 is connected by vertical guide piece with support arm 3, support arm 3 is connected by the horizontally-guided device with the measurement main shaft, measure the central axis of main shaft perpendicular to surface level, master gear 4 is fixed in to be measured on the main shaft, and the central axis of master gear 4 parallels with the central axis of workpiece for measurement 5; Measuring instrument is fixed on the support arm 3, and measuring instrument comprises data acquisition module, data processing module, data disaply moudle, and data acquisition module is connected with grating scale; Scroll chuck 6 is installed on the main body base 1, and workpiece for measurement 5 is fixed on the scroll chuck 6.
In the present embodiment, the horizontally-guided device that main body base 1 and column are 2 is the lead screw transmission guide piece; The vertical guide piece that column 2 and support arm are 3 is the line slideway guide piece; Support arm 3 and the horizontal guide rail device of measuring between main shaft are the line slideway guide piece.
Fig. 2 is the principle of work of present embodiment: have a leading screw can drive the motion of column 2 along continuous straight runs on the main body base 1, having a straight line guide rail can drive support arm 3 on the column 2 vertically moves, there is a straight line guide rail to drive on the support arm 3 and measures the motion of main shaft along continuous straight runs, master gear 4 can rotate around measuring main shaft, and grating scale all is installed on column and the support arm.At first scroll chuck is installed on the main body base 1, workpiece for measurement 5 is stuck in scroll chuck 6 lightly, then master gear 4 is installed in and measures on the main shaft, further adjusting master gear 4 by the horizontally-guided device of adjusting 1 of column 2 and main body base prepares to measure behind the position to be measured of workpiece for measurement 5, this moment, the position at master gear 4 places was initial position, and the parameter on the measuring instrument is initial parameter value; After measuring beginning, scroll chuck 6 drives workpiece for measurement 5 and begins rotation, master gear 4 is also along with workpiece for measurement begins rotation, because the end of workpiece for measurement is jumped, so that the position of master gear 4 changes, data acquisition module on the measuring instrument preserves the latest position parameter of master gear in real time, and is input to data processing module, and the result that data processing module will be processed is presented on the display module; In the present embodiment, the disposal route of data processing module is least square method, measure the actual round and in position postpone in workpiece for measurement female spline two ends by master gear 4, two best circles of match, then two circles after the match are connected together with line segment, the horizontal direction displacement x of master gear central axis, the vertical direction displacement of master gear is h, horizontal shift x, vertical displacement h and end face diameter d are brought in the mathematical formulae, and mathematical formulae is
