Description
Technical field
The invention belongs to laser welding technology field, it is related to a kind of clutch driven plate-drive plate structural member automatic preheating
Clamping device and method for laser welding.
Background technology
Clutch drived disk assy is one of widely used core component of friction clutch, it in the presence of diaphragm spring with
Flywheel contacts frictionally to transmit engine torque with platen.Hyundai Motor requires clutch plate to have and ensure that steady rising
Step, crash change of speed, decay electromotor are delivered to the vibration of variator, prevent the functions such as transmission noise, will meet these functions,
Generally clutch drived disk assy needs to install wavy spring piece, torsional vibration damper and damping controller etc. to reduce the torsion from electromotor
Shake and impact.
At present, the connected mode of the clutch plate of clutch drived disk assy-drive plate molectron (typical structure part) mainly adopts riveting
The mode connecing.This connected mode is primarily present problems with work：One is damping disk(-isc) tear.Due to isolated spring not
Can decay axial impact, therefore control assembly to decay axial impact using damping, because friction plate or damper assembly abrasion make
Damping disk(-isc) is produced with rivet cap interferes, or shock-absorbing spring is produced with clutch plate and damping disk(-isc) window edge under the action of the centrifugal force and rubs
Scouring is damaged, and above-mentioned reason leads to damping disk(-isc) stress to produce tear.Two is that frictional disk comes off.Its reason is that the moment of torsion of electromotor is complete
Rivet by connecting clutch plate and drive plate passes to variator side, and rivet bears huge shearing force and produces fracture, leads
Frictional disk is caused to come off.Three are to increase clutch plate axial space size.Abrasion in order to avoid producing rivet cap needs reserved certain
Axial space size, lead to shift time increase.
The presence of above-mentioned three point problem buries serious potential safety hazard to ride safety of automobile.For clutch plate-drive plate
Molectron, if using solder technology replace traditional riveting can for the internal structure design of clutch reserve bigger axial direction with
Radial space, design and application for torsion vibration absorber, preferable damping element etc. provide bigger design space, simultaneously also big
Big raising vehicle safety performance.
Laser welding technology due to having that speed is fast, depth big, deform little, solderable refractory material, foreign material and
The features such as untouchable welding, can be applied in the commercial production of automobile clutch, be clutch structure design with
Manufacture provides technical support.Domestic patent in terms of manufacturing clutch using solder technology, as China Patent No. is
ZL201510933409.3, invention entitled " a kind of clutch driven disc assembly and its mounting process ", publication date：2016 5
The moon 11, disclose a kind of clutch driven disc assembly and its mounting process, this patent is that corrugated sheet is arranged on damping disc
Outer edge, corrugated sheet is welded into one from damping disc by carbon-dioxide arc welding and two kinds of different welding manners of argon arc welding
Together with integrally it is ensured that being securely attached between damping disc and corrugated sheet, eliminating damping disc and cutting off at riveting with corrugated sheet
Potential risk.China Patent No. is ZL201610033168.1, invention entitled " heavy automobile clutch clutch drived disk assy ",
Publication date：On April 13rd, 2016, disclose a kind of clutch driven disc assembly, this patent adopt laser welding by driven disc with
Hub part forms an entirety, so that the integral rigidity of driven disc is significantly improved, solve stress concentration at conventional rivet connection and
The adverse effects such as riveting cracking.But, in above-mentioned two patents, describe only structure and its welding side of clutch driven disc assembly
Method and welding position, and clutch driven plate and the commonly used spring steel of drive plate and carbo-nitriding foreign material are manufactured,
There are problems in the welding of spring steel and carbo-nitriding material, as the problems such as crackle, pore, disclosed data does not have
Provide suitable welding procedure, also do not design efficient, reliable welder.

7. a kind of laser of the clutch driven plate-drive plate structural member automatic preheating clamping device as described in claim 1-6
Welding method is it is characterised in that specifically follow the steps below：
Step one, clutch plate (12) is placed on clutch plate backing plate (15), and fixed with the clutch plate on clutch plate backing plate (15)
Position pin (21) contacts, and makes clutch plate (12) be in tram；Shunk by controlling the piston rod of common cylinder (5), make tiltedly
Tongue mechanism passes through the centre bore of clutch plate (12), then turning knob (16), so that latch bolt (11) is stretched out and is pressed in clutch plate (12)
On；The piston rod controlling common cylinder (5) stretches out, and pulls down drive link (14), and drive link (14) drives latch bolt mechanism to transport downwards
Dynamic, thus clutch plate (12) is pressed on clutch plate backing plate (15)；
Step 2：Drive plate (13) is placed on drive plate backing plate (6), and positions with the drive plate on drive plate backing plate (6)
Pin (17) contacts, and makes drive plate (13) be in tram；The piston rod controlling revolution compression cylinder (7) shrinks, rocking arm (3)
Dextrorotation during declining turn 90 degrees, then carries nutating disk pressing plate (4) to move downward, and then drive plate (13) is compressed
On drive plate backing plate (6)；
Step 3：Open heating devices heat heater strip (19), set heating-up temperature, clutch plate (12) is entered with drive plate (13)
Row weld preheating；
While heating, open laser displacement sensor (1), lathe drives laser displacement sensor (1) to measure respectively and record
The height value of 3 points of A, B, C specifying on clutch plate (12), then measure the height value of the upper A1 point of drive plate (13), data is through putting
Big circuit transmission arrives computer, and computer calculates the upper A1 point of drive plate (13) and clutch plate (12) goes up the difference in height Δ h of A point；
If Δ h ≠ 0, computer sends adjustment signal to driver, controls motor (10) to rotate backward, is made by leading screw (8)
Drive plate backing plate (6) integrally raises Δ h, even if Δ h=0；Be sequentially adjusted in the height of upper B1, C1 point of drive plate (13) again so as to
Difference in height with upper B, C point of clutch plate (12) is 0, closes laser displacement sensor (1)；
Step 4：Implement laser welding；
Step 5：Postheating, sets the temperature of heater strip (19), and the clutch plate-drive plate structural member after welding is delayed
Cold；
Step 6：Thrust removal；Clutch plate hold-down mechanism resets, and controls the piston rod (22) of common cylinder (5) to shrink, makes tiltedly
House mechanism moves upwards and departs from clutch plate (12), and turning knob (16) makes latch bolt to contract；Drive plate hold down gag resets, control
The piston of system revolution compression cylinder (7) stretches out, and rocking arm (3) goes to the side of drive plate backing plate (6) with nutating disk pressing plate (4),
Finally take out clutch plate-drive plate welded unit.
8. the laser welding of clutch driven plate according to claim 7-drive plate structural member automatic preheating clamping device
It is characterised in that in described step 4, laser power is 3.0～3.4KW, speed of welding is 1.6～1.8m/min to method, from
Jiao measures as -3～+3mm, and welding track is circle, and protective gas is pure Ar.
