Situation Alarm, qualification determination indicator lamp 14 show orange-colored light, fasten " unqualified ", and qualification determination indicator lamp 14 shows redness
Light, and report to the police, point out operator currently to tighten information, be easy to reaction and judgement, and take counter-measure.
Power module bolt clamp device of the present utility model is added using moment of torsion control to the fastening control method of bolt and turns
Angle controls the process of two ore control, and whether bolt is tightened depending on clamping force size between bolt head and workpiece, moment of torsion control
The general principle of method is there is certain proportion relation according to tightening torque and clamping force, realizes indirectly folder by controlling Tightening moment
Clamp force size is controlled, generally, 90% consumption frictional force between frictional force and screw thread pair under bolt head of tightening torque, 10%
Clamping force is produced, i.e., by bolt head and screw thread pair friction effects, the final clamping fluctuation for producing of bolt fastening is larger, precision
It is poor.Controlling angle principle is measured up to anglec of rotation during sets target moment of torsion, rotation from after bolt head arrival binding face
It is qualified that angle is judged to when falling into certain setting interval.And it is by setting in the controller to judge whether bolt head reaches binding face
Determine torque value realization, because initial torque M of the torsion curve of different sized bolts1Value（What elastic deformation started
Value）Also it is different, but the tendency of curve is consistent, reaches M from moment of torsion1Start the measurement of corner during value, and bolt reaches patch
Torque value during conjunction face can be obtained by online torque sensor kinetic measurement, i.e., when torque value reaches M1During value, just
Assert that bolt head is fitted with binding face, this torque value is set in controller, as long as torque value reaches M1Value begins to corner
Control and detect, corner tightens online angular transducer on rifle measuring by being arranged at.And pass through Exemplary statistical data
Can show that a bolt tightens qualified region, when two control parameters of bolt tightening torque and the anglec of rotation all fall qualified area
In, can determine that bolt tighten it is qualified, so as to realize the control strategy of " moment of torsion control+controlling angle ".First bolt is tightened
To initial torque M1, will bolt tension to binding face, then, then rotate a certain angle, by bolt tension to elasticity or modeling
Property region, it is the elongation for controlling bolt that corner tightens the essence of method, in the elastic range axial pre tightening force with elongation into just
Than control elongation is exactly to control axial force, after bolt starts plastic deformation, although both are no longer proportional, but spiral shell
Mechanical property during bolt Tensile shows, as long as within being maintained at certain limit, axial pre tightening force just can be stable in yield load
Near, the control to tightening not only accurately is completed, and substantially increases the utilization rate of material.Moment of torsion control adds corner
When control is by detecting that two control parameters of moment of torsion and corner each fall within interval of acceptance, it is qualified that judgement bolt is tightened, if there is one
Parameter is unsatisfactory for requiring that being then considered as and tightening unqualified, control accuracy is higher, while power module bolt clamp device is also equipped with twisting
Tight tally function, can sets target fastening quantity, and show and currently fastened torsion bolt quantity, it is stubborn, not when there is bolt leakage
Tighten, when repetition is tightened, screw thread is slided tooth etc. and tightens unqualified, controller can quickly recognize out-of-the way position, and detection immediately is reported to the police simultaneously
Record is shown, is realized that bolt tightens on-line checking function, and is able to record that overall process data are tightened in preservation, bolt is effectively ensured tight
Stereoplasm amount, can the screw threads for fastening mass defect such as the leakage of effectively solving bolt is twisted, do not tightened, screw thread slides tooth, repeatedly tighten.
Fastener adopts disposable automatic tightening process, fastener to adopt and disposably tighten in two steps, substep
The benefit tightened is to prevent the decay of moment of torsion, and two steps tighten a time out depending on different sleeve models, set two steps
Respective rotating speed after, achievable bolt is once tightened step by step.
A kind of course of work of power module bolt clamp device of the present utility model is：First by selector sleeve power line
4th, tighten rifle power line 21 to be connected with controller 5, the Switching Power Supply 13 of opening controller 5, needed for selecting from selector sleeve
Sleeve 26 is attached to tighten the sleeve mounting rod 25 of rifle, and sleeve model used by 5 automatic identification of controller transfers corresponding tightening control
Program, when tightening control program includes the time-out between torque setting value, corner setting value, the respective tachometer value of substep, substep
Between numerical value etc., manually adjust and tighten rifle position and put, make 26 cutting ferrule of sleeve live bolt head, startup is tightened rifle and starts to tighten, by tightening journey
Sequence control is tightened rifle and carries out disposable substep automatic tightening to bolt, if tightening torque and corner meet requirement simultaneously, tightens rifle
Report " qualified ", unclamps start key 24, carries out next bolt fastening, if tightening torque or holding comer have a parameter to be unsatisfactory for
Require, tighten rifle report " unqualified ", and abnormal information is fed back to into controller display screen, unclamp start key, artificial access judges
Afterwards, eliminate abnormal.The fastening of all bolts in power module is sequentially completed, if bolt fastening quantity is consistent with program setting and entirely
Portion tightens, then controller declaration time is qualified, if rundown process leakage occurs and twists, do not tighten, sliding the exception such as tooth, controller is according to phase
Answer information alert to point out, after artificial elimination exception, reopen and tighten action, by this flow process, complete all bolts fastenings.
In other embodiment of the present utility model, twisting head may not be sleeve, or a word cutter head or
Cross cutter head；Installation base can also be set on base to form twisting head displacement structure, now sleeve is sheathed on installation base
On；Gravity sensor this detection means can not also be adopted, contactless detection means, such as infrared ray inspection can be adopted
Survey, RF transmitter and infrared receiver can be correspondingly arranged on the hole wall of installing hole, when infrared receiver is received
Prove during to infrared ray that corresponding sleeve is removed, when infrared receiver does not receive infrared ray, it was demonstrated that sleeve not by
Take away；The quantity of installing hole and aperture can be adjusted according to actual needs；Position of the installing hole on base can also basis
It is actually needed and is adjusted；Sleeve indicator lamp can also be not provided with base；Sleeve can also be located at installing hole in when telescopic spindle
Show that lamp is lighted, after sleeve is removed, sleeve indicator lamp extinguishes；Up and down stretching structure can also be electric pushrod, now can be with
Spring is not used.
