As can be seen here, coordinate force between input shaft 1 upper spline portion 11 and spline housing plays vital effect to the safety of human pilot, if coordinate force is too large, reappearing bearing circle while clashing into may not can move down, so just likely the health of human pilot is caused to larger injury, if coordinate force is too little, likely affect the normal driving of vehicle.Therefore be necessary output shaft spline and spline housing coordinate force to detect, and also there is no a kind of cubing with this measuring ability at present.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of cubing that can measure the coordinate force between input shaft upper spline portion and spline housing.
For achieving the above object and other relevant objects, the utility model provides a kind of input shaft spline fitted power cubing, one end of described input shaft is spline, the middle part of described spline is injection moulding spline part, this input shaft spline fitted power cubing comprises: an input shaft fixture, and described input shaft fixture is used for clamping input shaft; One pull bar, described pull bar one end is provided with a radial hole, is provided with the spline adapting with input shaft upper spline in described radial hole; One mobile platform, described mobile platform is provided with a force-measuring gauge, and described force-measuring gauge is fixedly connected with one end away from spline on described pull bar, and described mobile platform is positioned at a side of described input shaft fixture; Driving mechanism, described mobile platform is connected with described driving mechanism, and described driving mechanism drives pull bar radial direction described in described mobile platform to move around.
Preferably, described driving mechanism comprises a screw mandrel, and described mobile platform is fixedly connected with nut slider, and described nut slider coordinates with described wire rod thread.
Preferably, one end of described screw mandrel is provided with handle.
Preferably, described mobile platform is provided with for supporting the back-up block of pull bar.
As mentioned above, input shaft spline fitted power cubing of the present utility model has following beneficial effect: this cubing in use, input shaft is fixed on input shaft fixture, input shaft and pull bar coaxially arrange, make the radial hole on pull bar relative with the spline position of input shaft, then by driving mechanism, first drive mobile platform to move to input shaft direction, spline on input shaft is inserted in the spline on pull bar, the demonstration of force-measuring gauge is observed in the position of inserting according to input shaft, thereby can determine the size of input shaft spline fitted thrust, then by the reverse mobile mobile platform of driving mechanism, the spline of input shaft is pulled out in the spline of pull bar, so just can determine the size of input shaft spline fitted pulling force.As can be seen here, adopt this cubing to the pulling force of input shaft spline fitted and thrust, to detect simultaneously, can effectively improve the quality of input shaft.
