Description
Technical field
The present invention relates to auto parts assembling field, the wheel hub mother nut that relates to a kind of mechanical automation is concretely tightened and bearing pre-fastening measuring machine and method of application thereof.
Background technology
Along with the continuous development of industry, automobile industry also obtains very fast development, people to the requirement of car mass also in continuous raising, particularly relatively strict to the requirement of the assembling of automotive hub mother nut and bearing pre-fastening.At present, many automobile productions producer generally adopts artificial assembling when the wheel hub mother nut is assembled; Bearing pre-fastening is being detected, when finding that pretightning force does not meet the demands, again mother nut is being tightened or unscrewed; Needs operating repeatedly when causing at every turn assembling wheel hub; Waste time and energy, can not realize the mechanical automation operation, lost labor's cost.
Summary of the invention
In view of the defective that prior art exists, the present invention will provide a kind of wheel hub mother nut of mechanical automation to tighten and bearing pre-fastening measuring machine and method of application thereof.
For realizing above-mentioned purpose; The technical solution that the present invention adopted is that a kind of wheel hub mother nut is tightened and the bearing pre-fastening measuring machine, and it comprises: rotating shaft, first servomotor, second servomotor, socket wrench specially adapted for it, revolution measuring wrench are measured in preceding shrouding, back shrouding, operating grip, protective cover, guide pillar, suspender, nut screwing clamping axle, gear, revolution; It is characterized in that: the back shrouding is provided with that operating grip, preceding shrouding are connected with guide pillar with protective cover, guide pillar is connected with suspender, preceding shrouding is provided with the nut screwing clamping axle, the nut screwing clamping axle is through gear and turn round the measurement rotating shaft and be connected; Nut screwing clamping axle one end is connected with first servomotor; The other end is connected with socket wrench specially adapted for it; Revolution is measured rotating shaft one end and is connected with second servomotor, and the other end is connected with the revolution measuring wrench.
The wheel hub mother nut is tightened and the basic method of application of bearing pre-fastening measuring machine, and its step is following:
After a, workpiece put in place, artificial with mother nut bring into 2 ~ 3 buckle after, the wheel hub mother nut is tightened and bearing pre-fastening measuring machine aligning mother nut pushes away forward, make socket wrench specially adapted for it over against last mother nut.
B, when socket wrench specially adapted for it during over against last mother nut; Switch on operator's crawl operating grip; Make the revolution measurement axis be inserted in the bolt neutral, press start button then, the nut screwing clamping axle automatic fastening nut of meeting also detects the bearing impaction state; When moment reached certain value, system can start " revolution measurement axis " automatically and drive the wheel hub rotation and detect rotating torque in real time.
C, repeat preceding step, measure while tightening, when flywheel moment and screw-down torque all reached predetermined value, the nut screwing clamping axle stopped earlier tightening, and the revolution measurement axis continues to measure, if measured value still meets the demands, then this tighten, the measuring process end; If measured value does not meet the demands, then the nut screwing clamping axle starts once more, and according to flywheel moment automatic decision torsional direction bigger than normal or less than normal, all reaches predetermined value up to screw-down torque and flywheel moment.
D, tighten measure to finish after, system can judge according to measurement result tighten, whether measurement result qualified, when qualified, the qualified lamp on the control panel of joystick is lighted; If system can send sound when finding abnormal conditions are arranged, light is reported to the police, remind the operator.
Said wheel hub mother nut is tightened and the bearing pre-fastening measuring machine is provided with a kind of measuring method of tightening: the front rundown process tighten with the wheel hub mother nut and the basic method for using of bearing pre-fastening measuring machine identical; After reaching preset moment; The auto-reverse predetermined angular of nut screwing clamping axle, and then start the revolution measurement; And then judge that based on measurement result the nut screwing clamping axle need tighten or continue to unscrew mother nut; After pretightning force is qualified, tightens measuring process and promptly accuse completion.
Advantage of the present invention and effect are: the wheel hub mother nut is tightened and the bearing pre-fastening measuring machine is made up of two cover screwing axles, and a cover is used for mother nut to be tightened, and the another set of bearing pre-fastening that is used for is measured; Two sleeves are sleeved on together, and promptly measurement axis is sleeved on the output shaft of tightening axle with coaxial manner and exports, thereby a middle output shaft is used to tighten mother nut and controls screw-down torque guarantee cone bearing is produced certain snap-in force; Peripheral one is used to detect the pre-fastening moment that the wheel hub rotating torque is a bearing, with tightening of wheel hub mother nut and the detection of bearing pre-fastening is tightened through a chaptrel hub mother nut and the bearing pre-fastening measuring machine just can be realized simultaneously, provides many sets of plan of tightening measurement can supply the user to select simultaneously; Make easy and simple to handlely, assembly precision is high, and moment of torsion is even; Measure accurately; Time saving and energy saving, reached unmanned full automatic working, save labour turnover.
