Completing generation axial float in assembling with needle bearing causes bearing to depart from, so as to cause universal joint to be scrapped, it is necessary to using riveting
Method axial limiting is carried out to needle bearing.In order to solve this problem, mainly directly riveted using riveted joint,
Because the section fork workpiece of dress crossed joint and needle bearing is that forging is formed, section fork workpiece wall is thin, is produced under the rivet force of high pressure
The deformation of section fork workpiece openings, causes upper and lower two riveting points depth uneven.
The content of the invention
It is suitable it is an object of the present invention to provide one kind riveting uniform depth, crossed joint and needle bearing clearance, life is greatly improved
Produce the crossed joint riveting machine of efficiency.
The present invention is adopted the following technical scheme that：A kind of crossed joint riveting machine, including cylinder of forging a knife, adjusting nut, locking screw
Mother, push rod, spring, fixed block, connecting rod, positioning sleeve, riveting section header, section fork workpiece, locating piece, adjustable spring, base plate, base plate
The upper end left and right sides is respectively provided with cylinder of forging a knife, and the middle part between two cylinders of forging a knife sets locating piece, a left side for locating piece
Right both sides are respectively provided with fixed block, and connecting rod, positioning sleeve, riveted joint are respectively provided with the fixed block in left side, connecting rod
Left side sets spring, and spring is nested with push rod, adjusting nut, locking nut is respectively provided with the left of push rod, positioned at right side
The right side of fixed block sets and is nested with the adjustable spring on push rod；Section fork workpiece is clamped on locating piece.
The upper end of fixed block of the present invention sets U-shaped groove.
Gland is respectively provided with the outside of fixed block of the present invention.
The present invention puts section fork workpiece into locating piece, and pressing switch makes the cylinder take-off lever of forging a knife at two ends while promoting tune
Section nut, adjusting nut drives push rod to be run to inner side, and positioning sleeve and riveted joint are driven with the connecting rod that push rod links together
Together to medial motion, the positioning sleeve stop motion in the presence of adjustable spring when positioning sleeve touches section fork workpiece one end,
Riveted joint continues to be extruded to inner side under the thrust of cylinder of forging a knife, so as to be riveted to section fork workpiece needle bearing hole, now
The part of section fork workpiece both sides is synchronous operation, carries out riveting to crossed joint two needle bearing hole and terminates.The depth of riveting
Can be by adjusting adjusting nut, depth adjustment tightens locking nut after terminating, and a course of work terminates.Taken from locating piece
Go out cross and pitch workpiece successively, other end of section pitched workpiece after upset be put into the section fork workpiece that locating piece riveted and stick into positioning
In the slot to make way of block.Above-mentioned action is repeated, four riveting points riveting that cross pitches workpiece successively terminates.
The present invention is supported by positioning, and cylinder is promoted, and realizes Hooke's joint riveting assembling, to section fork workpiece inner wall
Width has carried out limited support, and dress section fork workpiece inner width is fitted into spacing frock, and another section fork workpiece is rotated by 90 ° to be put
To enter get out of the way in frock groove and crossed joint both-end is riveted, due to consistent, the operation that limits section fork workpiece deformation riveting point depth
Simply, riveting quality and efficiency are improve, product rejection rate, riveting uniform depth, crossed joint and needle bearing clearance is reduced
Properly, production efficiency is greatly improved.
