As shown in fig. 1 to 3, the assembly fixture a includes a support plate 1 and a centering spline shaft 5 disposed on the support plate for being matched and positioned with a center hole of a flywheel, and a set of clamping jaw mechanisms for clamping a clutch b on the flywheel c is disposed on the support plate 1. The centering spline shaft 5 is provided at the center position of the support plate.
The edge of the supporting plate 1 is outwards provided with a group of protrusions which extend out, and each protrusion is provided with a clamping jaw mechanism. Preferably, the number of the protrusions extending out of the supporting plate is three, the protrusions are arranged in a structure with an included angle of 120 degrees, and three points are clamped stably and reliably.
The supporting plate 1 is provided with a working pressure plate 6 for supporting the compression clutch, the working pressure plate is arranged at the center of the supporting plate, and the centering spline shaft penetrates through the working pressure plate.
The supporting plate 1 is provided with a centering spline shaft supporting frame 8, and the centering spline shaft 5 is arranged on the centering spline shaft supporting frame 8 through an adjusting spring 7, so that the centering spline shaft is conveniently aligned with a center hole of the flywheel.
The three clamping jaw mechanisms have the same structure; the clamping jaw mechanism preferably comprises an air cylinder 11, a limiting guide rod 9, a sliding block 10 and a fixed jaw 4 used for being clamped on the edge of the flywheel, the air cylinder and the limiting guide rod are fixed on a supporting plate, the sliding block is slidably arranged on the limiting guide rod, a guide groove is formed in the sliding block, the fixed jaw can slide relatively in the guide groove, the inner end of the fixed jaw 4 is hinged with a piston rod of the air cylinder, and a pressing plate is arranged on the inner side of the outer end of the fixed jaw.
The limiting guide rod 9 is arranged perpendicular to the supporting plate. A piston rod of the cylinder 11 is provided with a cylinder connecting rod 3 which is hinged with a fixed claw hinge 2 arranged at the inner end of the fixed claw; the side of the fixed claw hinge close to the sliding block is provided with a plane matched with the sliding block, so that the position of the fixed claw can be conveniently adjusted during clamping, the pressing plate is perpendicular to the limiting guide rod, and the clamping is stable and reliable. And a reversing valve 12 for switching the working direction of the cylinder is arranged on the supporting plate.
Specific examples are:
the tooling support plate is arranged into three convex plate blocks, a structure with 120-degree included angle distribution is arranged between the convex plate blocks, mounting holes for mounting the centering spline shaft support frame, the working pressure plate, the limiting guide rod and the air cylinder are arranged on the support plate, and an adjusting spring is arranged on the centering spline shaft support frame.
The stroke design of the limiting guide rod is set based on the free state and the assembly height of the clutch, and when the clutch is in the free state, the limiting guide rod is in the maximum stroke, so that the assembly of the centering spline shaft is facilitated; when the clutch is in an assembling state, the limiting guide rod is in the minimum stroke, so that the mounting end face of the clutch is completely attached to the step face of the flywheel.
The slide block is used for switching the fixed claw between a free state and a clamping state; when in a free state, the sliding block is positioned at the most front section of the limiting guide rod, namely the fixed claw is in a free opening state; when in a clamping state, the sliding block is positioned at the position of the fixed hinge, namely the fixed claw is in a clamping state; in the clamping state, the sliding block is in the middle position of the limiting guide rod, namely the fixed claw is in the clamping state; at the moment, the sliding block is adjusted to the position of the fixed claw hinge through the auxiliary cylinder, so that the fixed claw is perpendicular to the limiting guide rod, the fixed claw is ensured to be perpendicular to the flywheel end, and clamping is facilitated.
Centering and positioning: the centering spline shaft is held by hand and the tool supporting plate is pushed slightly to enable the spline shaft at the end of the working pressing plate to penetrate through the clutch cover assembly and the spline of the clutch driven plate and be inserted into the center hole of the flywheel, three pin holes in the clutch cover are synchronously adjusted to be kept vertical as much as possible and then aligned with three positioning pins on the flywheel.
The clamping function is as follows: after the positioning pin is matched and assembled with the pin hole, the reversing valve is shifted, the fixture can automatically clamp the flywheel, the driven plate and the clutch cover assembly according to a set assembly position by the fixed claw, namely, the cylinder is pressurized to pull the cylinder connecting rod, the fixed claw hinge and the fixed claw to tighten the stroke, the synchronous sliding block slides towards the working pressure plate end, when the position of the hinge is reached, the pressure plate of the fixed claw can be perpendicular to the limiting guide rail, namely, the fixed claw hooks the flywheel flange, and the clamping state of the fixture is realized; at the moment, the clutch mounting bolts are sequentially screwed down according to the sequence, so that the assembly of the clutch is completed, the diagonal and re-tightening operations are not needed, the assembly time can be relatively saved, and the assembly efficiency is improved.
Resetting the tool: after a clutch mounting bolt is screwed down, the centering spline shaft is held by hand and the reversing valve is stirred, at the moment, the air cylinder builds pressure to push the air cylinder connecting rod, the fixed claw hinge and the fixed claw to release the limit stroke, the synchronous sliding block slides to the flywheel end, when the sliding block reaches the maximum stroke position of the limit guide rail, the fixed claw and the limit guide rail form a certain angle, namely, the fixed claw is separated from the flywheel flange at the moment, and the free state of the tool is realized; and (4) centering the spline shaft by hand, slightly pulling the tool supporting plate, and separating the tool from the clutch to prepare for the next assembly.
The above-mentioned features are merely for describing preferred embodiments of the present invention and may be arbitrarily combined to form a plurality of embodiments of the present invention.
