Description
Technical field
The present invention relates to a kind of automobile diaphragm spring clutch that is used for separates to refer to beat and proofreaies 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: at first; Because diaphragm spring has nonlinear characteristic, therefore can be designed to behind friction disc wear, spring pressure almost can remain unchanged; And the pedal force in the time of can alleviating cut-off clutch makes manipulation 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 with overall circumferential contact, make pressure distribution even, the contact of friction plate is good, and wearing and tearing evenly also are easy to realize good heat dissipation ventilation etc.Along with auto vendor is harsh day by day to the requirement of NVH, the diaphragm spring clutch tolerance is strict more.Refer to the ride comfort of jumping effect clutch and the comfortableness of manipulation because diaphragm spring separates, product design require to separate refer to jerk value 1.0 till now 0.6 in addition lower.Because diaphragm spring has originally been held the effect of holddown spring and separator levers; Platen, lid and diaphragm spring are from process, there being tolerance; Directly cause diaphragm spring clutch assembly diaphragm spring to separate to refer to beat after the assembling and be difficult to satisfy customer requirement, must proofread and correct.
It is L ± 1 that common diaphragm spring clutch separates the jointing altitude that refers to, beating is 0.6.The finger of product separation now closes and highly is can guarantee L ± 1st, but jerk value 0.6 is difficult to assurance, can only be through proofreading and correct solution; Existing method is that the operative employee detects data based on dial gauge; Take a benchmark to refer to size then, will proofread and correct above the separation fingering row of the margin of tolerance, too high size is proofreaied and correct downwards; Cross on the low size height and proofread and correct, make its jointing altitude and jerk value scope in regulation.This existent method efficient is low, and homogeneity of product is poor.
Continuous development along with automatic control technology is used in assembling process provides technical foundation for developing automated arm in the assembling process.Assembly line presents new development trend, and beat, GRR, process capability have been proposed requirements at the higher level, separates to refer to beat to diaphragm spring clutch and proofreaies and correct and detect, and needs to propose a kind of new test method and checkout gear.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point; Provide a kind of automobile diaphragm spring clutch to separate and refer to beat correction and detection method; Separate and to refer to the requirement of beating to satisfy diaphragm spring clutch, and provide and respectively separate the authentic data that finger closes height.
The present invention adopts following technical scheme for the technical solution problem:
Automobile diaphragm spring clutch of the present invention separates to refer to beat to be proofreaied and correct and the characteristics of detection method are: at first through product and tolerance design, diaphragm spring clutch is separated finger close highly and be controlled in the scope of (L-1) ± 1; Proofread and correct then and detect; Said correction and detection are to adopt servomotor to drive screw-jack; Upward pushing tow is pointed in the separation of diaphragm spring clutch, make said separation refer to produce deformation, and make the separation finger close the size range that highly reaches regulation through deformation; Guarantee that separation refers to beat in the margin of tolerance of regulation, wherein L closes the height standard value for separating finger.
Automobile diaphragm spring clutch of the present invention separates to refer to beat to be proofreaied and correct and detection method is undertaken by following process:
A, location position diaphragm spring clutch with plane of orientation and alignment pin, utilize the descending of gas-liquid power-increasing cylinder, are pressed on the bolt hole place of diaphragm spring clutch with cylindrical piece, make diaphragm spring clutch obtain the location;
B, spacing based on separating the number that refers in the diaphragm spring clutch, is provided with the slide block of respective amount above said diaphragm spring clutch, each slide block is displaced downwardly to corresponding separation refers to the medium position place, refers to carry out up spacing to said separation;
C, correction; Correction screw-jack by the correcting servo driven by motor is set below said diaphragm spring clutch; To separate the front end that the refers to pushing tow that makes progress by said correction screw-jack; Make to separate and refer to produce deformation; Until the size range that reaches regulation, guarantee that separation refers to beat in the margin of tolerance of regulation;
D, detection adopt stepper motor to drive displacement transducer, measure each one by one and separate the height value that refers to, all each separate and refer to that maximum is to separate with the difference of minimum of a value between the height value and refer to beat.
Automobile diaphragm spring clutch of the present invention separates to refer to beat to be proofreaied and correct and the version of checkout gear is to be provided with:
One workbench, diaphragm spring clutch are and lie in a horizontal plane on the workbench, and gas-liquid power-increasing cylinder is set above said workbench, and the piston rod front end of said gas-liquid power-increasing cylinder is pressed on the place, bolt hole position of diaphragm spring clutch through cylindrical piece;
One position-limit mechanism according to separating the number that refers to, is provided with the slide block of respective amount above said diaphragm spring clutch, the corresponding spacing medium position place that refers in separation of each slide block that moves down is spacing to said separation fingering row;
One aligning gear; Correction screw-jack by the correcting servo driven by motor is set below said diaphragm spring clutch; To separate the front end that the refers to pushing tow that makes progress by said correction screw-jack; Produce deformation through the front end that separation is referred to and make each diaphragm separate the size range that refers to and reach regulation, and guarantee that diaphragm separates beating in the margin of tolerance of stipulating of referring to;
One testing agency drives displacement transducer to detect with stepper motor, measure each one by one and separate the height that refers to, all each separate and refer to that maximum is to separate with the difference of minimum of a value between the height value and refer to beat.
The inventive method is through product and tolerance design; Diaphragm spring clutch is separated finger to be closed highly and is controlled in the scope of (L-1) ± 1; Proofread and correct screw-jack through the correcting servo driven by motor then; To separate and point to go up pushing tow and make it produce deformation,, guarantee to separate the scope that the jointing altitude that refers to and jerk value are being stipulated until reaching standard size L.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, the inventive method is reliable, and homogeneity of product is high;
2, the inventive method efficient is high, and once correction puts in place and realizes measuring;
3, the inventive method can quantitatively show the jointing altitude that each separation refers to, avoids only having qualitative detection result's deficiency.
