Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention
Specific embodiment of the present utility model.
A kind of hindley screw irregularly-shaped inner hole diameter dimension rapid measurement device of embodiment 1
As shown in figs. 1-7, the utility model provides a kind of hindley screw irregularly-shaped inner hole diameter dimension rapid measurement device, is
A kind of quick and precisely measuring device of steering assembly hindley screw diameter of bore, it is described such as attached drawing 5, including conical core shaft 3
Detection axle sleeve 4 is housed in conical core shaft 3, detection in the uniformly distributed inner hole of axle sleeve 4 equipped with double radially uniformly distributed totally 8 etc.
The steel ball 5 of diameter.
In order to guarantee the rapid survey of hindley screw diameter of bore, measurement method is by using the detection of multiple groups inner hole feeler gauge to be changed to
It is detected using conical core shaft 3 plus 5 mode of hardened steel ball rolled.
To guarantee that steel ball 5 uniformly distributed in the detection device can be directed at diameter phi D measurement portion on 6 inner hole circumference of hindley screw
Position, detection in 4 outer circle of axle sleeve with being machined with the groove of its centerline parallel for carrying out to the key of hindley screw 6 inner hole protrusion
Limit and guiding.
To guarantee quickly to read the size of 6 diameter of bore of hindley screw, detection is with being machined with length phase in conical core shaft 3
Between, equidistant groove.
Holding surface-worm 6, the other hand hold conical core shaft 3, the detection axle sleeve 4 of measuring device are put on the other hand when measurement
The special-shaped spline inner hole of hindley screw 6, the hindley screw with special-shaped spline inner hole are this detection device workpiece detected, are protected
Card detection is adjacent to 4 end face of axle sleeve and the end face of hindley screw 6.The insertion detection of conical core shaft 3 that will test device after being adjacent to is used
In the inner hole of axle sleeve 4, until making steel ball 5 and 6 irregularly-shaped inner hole of hindley screw and spindle taper with the increasing of 4 diameter of conical core shaft
Until the contact of 3 outer circles makes spindle taper 3 stop being axially moved, this can be read according to the exposed groove in conical core shaft left end at this time
The irregularly-shaped inner hole diameter dimension of hindley screw.
It is straight can quick and precisely to measure its irregularly-shaped inner hole before hindley screw press fitting for the measuring device made using the above scheme
Diameter value is no longer detected with several groups of feeler gauges, is greatly improved detection working efficiency, while can reduce hindley screw detection workman labor again
Fatigue resistance.
Specifically, the utility model provides a kind of hindley screw irregularly-shaped inner hole diameter dimension rapid measurement device, including cone
