Description
Technical field
The present invention relates to a kind ofly for automobile diaphragm spring clutch separation finger, beat and proofread and correct and detect test method.
Background technology
Diaphragm spring clutch is to have replaced general helical spring and declutcher control lever mechanism and the clutch made with diaphragm spring, diaphragm spring clutch has lot of advantages: first, because diaphragm spring has nonlinear characteristic, therefore can be designed to after friction disc wear, spring pressure almost can remain unchanged, and the pedal force in the time of can alleviating cut-off clutch, makes to handle light; Secondly, diaphragm spring has originally been held the effect of holddown spring and separator levers, and the structure of clutch is greatly simplified, and number of parts reduces, and quality reduces and shortened significantly its axial dimension; In addition, because diaphragm spring and platen are to contact with whole circumference, make pressure distribution even, the contact of friction plate is good, and even wearing is also easy to realize good heat dissipation ventilation etc.Along with auto vendor is day by day harsh to the requirement of NVH, diaphragm spring clutch tolerance is stricter.Because the ride comfort that diaphragm spring separation finger jumping effect clutch engages and the comfortableness of manipulation, product design requires separation finger jerk value 1.0 till now 0.6 even lower.Because diaphragm spring has originally been held the effect of holddown spring and separator levers, platen, lid and diaphragm spring are from there is tolerance in process, directly after assembling, causing diaphragm spring clutch assembly diaphragm spring separation finger to beat is difficult to meet customer requirement, must proofreaies and correct.
Conventionally the jointing altitude of diaphragm spring clutch separation finger is L ± 1, and beating is 0.6.Separation of products refers to that jointing altitude is L ± 1, can guarantee now, but jerk value 0.6 is difficult to guarantee, can only solve by correction, existing method is that operative employee is according to centimeter check data, then take a benchmark to refer to size, the separation finger that surpasses the margin of tolerance is proofreaied and correct, too high size is proofreaied and correct downwards, on too low size height, proofread and correct, make its jointing altitude and jerk value in the scope of regulation.This existing method efficiency is low, and homogeneity of product is poor.
Development along with automatic control technology is applied in assembling process, provides technical foundation for developing automated arm in assembling process.Assembly line presents new development trend, and beat, GRR, process capability have been proposed to requirements at the higher level, for diaphragm spring clutch separation finger, beats and proofreaies and correct and detect, and need to propose a kind of new test method and checkout gear.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, providing a kind of automobile diaphragm spring clutch separation finger to beat proofreaies and correct and detection method, to meet the requirement of beating of diaphragm spring clutch separation finger, and provide the authentic data of each separation finger jointing altitude.

C, correction, correction screw-jack by correcting servo driven by motor is set below described diaphragm spring clutch, by described correction screw-jack by the front end of the separation finger pushing tow that makes progress, make separation finger produce deformation, until reach the size range of regulation, guarantee that separation finger beats in the margin of tolerance of regulation;
D, detection, adopt stepper motor to drive displacement transducer, measures one by one the height value of each separation finger, and between all each separation finger height values, the difference of maximum and minimum of a value is separation finger and beats.
Automobile diaphragm spring clutch separation finger of the present invention is beated and is proofreaied and correct and the version of checkout gear is to arrange:
One workbench, diaphragm spring clutch is and lies in a horizontal plane on workbench, and gas-liquid power-increasing cylinder is set above described workbench, and the bolt hole position that the piston rod front end of described gas-liquid power-increasing cylinder is pressed on diaphragm spring clutch by cylindrical piece is located;
One position-limit mechanism according to the number of separation finger, arranges the slide block of respective amount above described diaphragm spring clutch, and each slide block moving down is corresponding spacing at the medium position place of separation finger, to described separation finger, carries out spacing;
One aligning gear, correction screw-jack by correcting servo driven by motor is set below described diaphragm spring clutch, by described correction screw-jack by the front end of the separation finger pushing tow that makes progress, by making the front end of separation finger produce the size range that deformation makes each diaphragm separation finger and reaches regulation, and guarantee the beating in the margin of tolerance of regulation of diaphragm separation finger;
One testing agency, drives displacement transducer to detect with stepper motor, measures one by one the height of each separation finger, and between all each separation finger height values, the difference of maximum and minimum of a value is separation finger and beats.
The inventive method is by product and tolerance design, diaphragm spring clutch separation finger jointing altitude is controlled in the scope of (L-1) ± 1, then by correcting servo driven by motor, proofread and correct screw-jack, make it produce deformation the separation finger pushing tow that makes progress, until reach standard size L, guarantee the jointing altitude of separation finger and the scope that jerk value is being stipulated.
Compared with the prior art, beneficial effect of the present invention is embodied in:
