The spline body is provided with an inner chamber with splines; the inner chamber of the rolling probe seat is placed on the step excircle of the spline body; the table chuck and the upper end of the rolling probe seat are in fixed connection; the first measuring head is in fixed connection with the lower end of the rolling probe seat and is located in the groove at the lower end of the spline body; the second measuring head is in fixed connection with the center-pole of the dial gauge and is located in the groove located at the upper end of the spline body; the inner chamber of the retaining ring is assembled on the excircle of the rolling probe seat; the end cover presses the upper end step end surface of the spline body and is in connection with the upper end surface of the retaining ring. The hand-held male spline M value special-purpose measuring instrument can simplify the measurement mode of M value (cross-rod distance) and raise measurement precision, is portable and rapid to operate and is especially suitable for the on-line detection of large batch production.
Description
Technical field
The utility model relates to a kind of surveying instrument, specifically a kind of for measuring the handheld specialized measuring instrument of involute outer spline M value (also claiming across rod distance) actual value.
Background technology
At automobile power assembly, drive assembly, turn in assembly, it is very general that axial workpiece adopts involute spline to connect with the mode of transmission, and M value (across rod distance) size is one of important parameter of controlling male splines precision, be to control the conventional effective means of spline precision.Along with producing the enterprise of involute spline, be on the increase, also more and more higher to the accuracy requirement of spline.At present, most enterprises is used the actual value measuring instrument of a kind of male splines M value (across rod distance), during measurement, measuring instrument need be connected on test desk and can be measured by revoliving arm, this kind of metering system be complicated operation not only, and heavier because of it, mobile also inconvenience, also needs to adjust according to measuring length and measuring position sometimes.
Summary of the invention
Technical problem to be solved in the utility model be to propose a kind of both can simplify M value (across rod apart from) metering system, can improve its measuring accuracy again, operate light, hand-held male splines M value Special measuring instrument fast.
For solving the problems of the technologies described above, the utility model hand-held male splines M value Special measuring instrument comprises spline body, rolling measuring head base, keep circle, end cap, the first measuring head, the second measuring head, clock gauge, table chuck and calibrating device, described spline body is provided with the inner chamber with spline, the inner chamber of described rolling measuring head base is placed on the step cylindrical of described spline body, the upper end of described table chuck and described rolling measuring head base is fixedly linked, the lower end of described the first measuring head and described rolling measuring head base is fixedly linked and is placed in the set groove in described spline body lower end, the center-pole of described the second measuring head and described clock gauge is fixedly linked and stretches into described table chuck inner chamber and is placed in the set groove in described spline body upper end, the inner chamber of described maintenance circle is assemblied on the cylindrical of described rolling measuring head base, described end cap be pressed on described spline body upper end step end face and with keep circle upper surface be connected.
The utility model is owing to having adopted above-mentioned technical pattern, during measurement, with calibrating device, benchmark (is first assumed to be tested male splines calibrating device and inserts spline body, clock gauge to zero-bit), then change tested part, make it and spline body, the interactive engagement of two measuring heads, and be passed to clock gauge, read indicating value poor, be known this spline M value (across rod distance) actual value size, thereby can classify to part.The measuring head of the utility model measuring instrument is determined according to tested male splines length bar (ball) size, calibrating device across rod apart from being standard value with length bar (ball), the numerical value reading is the difference of M value (across rod distance) and standard value, error is little, there is higher measuring accuracy, can also go out by measuring the different cross section position measurement of male splined shaft the tapering, ovality of spline M value (across rod (ball) distance) size etc. simultaneously, greatly improve amount instrument applicability.The utility model measuring instrument simplicity of design, it is convenient to measure, operate light, quick, both simplified M value (across rod apart from) metering system, improved again its measuring accuracy and measuring speed, saved the time, the online detection that is specially adapted to produce in enormous quantities uses.

Embodiment
As shown in Fig. 1 and Fig. 1-1, the utility model hand-held male splines M value Special measuring instrument comprises spline body 1, the second measuring head 2, the first measuring head 3, clock gauge 4, end cap 5, keeps circle 6, table chuck 7, rolling measuring head base 8(be please refer to Fig. 3 and Fig. 3-1) and calibrating device 9(please refer to Fig. 4 and Fig. 4-1).Please refer to Fig. 2 and Fig. 2-1, spline body 1 is provided with the inner chamber with spline, rolling measuring head base 8 is placed on the step cylindrical of spline body 1, table chuck 7 is fixedly linked with the upper end of rolling measuring head base 8, the first measuring head 3 is fixedly linked and is placed in the set groove in spline body 1 lower end seat 8 lower ends with the survey of rolling, the second measuring head 2 is fixedly linked and is placed in the set groove in spline body 1 upper end by showing the inner chamber of chuck 7 with the center-pole of clock gauge 4, keep the inner chamber of circle 6 be assemblied on the cylindrical of rolling measuring head base 8 and be connected with the step end face of spline body 1, end cap 5 is pressed on the upper end step end face of spline body 1 and is connected with keeping the upper surface of circle 6.Spline body 1 and the calibrating device 9 while measuring adopt tool steel to make, wear-resisting and use for a long time indeformable.The first measuring head 3, the second measuring head 2 have adopted alloy material manufacture, use for a long time and needn't change any parts, can be the use cost that enterprise reduces measurer greatly.Because this measuring method is to utilize calibrating device to zero-bit, adopt comparative method for measuring, in measuring process, there is not human factor, measured value is correctly stable, and measuring accuracy is higher, and effect is fairly obvious.Measuring head adopts the manufacture of alloy material, not easy to wear, has also improved accuracy of detection in the time of durable.
