The technical solution adopted for the present invention to solve the technical problems is: a kind of cylinder type cylindrical roller bearing automatic assembly machine; Be installed on the table top; Comprise supply disk, cylindrical roller assemble mechanism, assembling mould and electric control box, said cylindrical roller assemble mechanism comprises an assembling push rod, propelling push rod, assembling cylinder and a propulsion cylinder, and assembling cylinder piston rod external part end is fixedly connected with assembling push rod one end end; Propulsion cylinder piston rod external part end is fixedly connected with advancing push rod one end end; Said assembling mould comprises that die holder and one are connected the broken ring that mould is taken the surface, and said broken ring and die holder form a cavity that is used to place bearing inner race, and the feeding tube outlet port of said supply disk has positioning pipe; The positioning pipe outlet end is fixedly connected on the broken ring opening; The bottom of said positioning pipe has is convenient to the opening slot that cylindrical roller passes through, and the opening of the broken ring on said opening slot and the die holder aligns, and the external part of said assembling push rod is over against opening slot; Advance push rod and the angled setting of assembling push rod, the external part of propelling push rod is towards the broken ring direction and be higher than the broken ring setting.
In order effectively to fix bearing inner race; Make things convenient for the roller assembling, said cavity comprises out the circular groove and the sleeve column that is used for fixing bearing inner race at the die holder upper surface, and the circular groove bottom is fixedly connected sleeve column; Said broken ring is concentric with circular groove, and the A/F of broken ring is more than or equal to the cylindrical roller diameter.
In order to realize that roller is pushed to inner ring raceway, said assembling push rod becomes 40 °～41 ° angles with the propelling push rod.Select such angle; Can guarantee to advance push rod when advancing, can not push up bearing inner race, cause the problem that scratches, advance push rod to promote roller in inner ring raceway, advance Shi Buhui and broken ring interference simultaneously; Guaranteed that roller is not scratched, be convenient to each roller advancing safely and fast forward.
In order to guarantee that cylindrical roller correctly is pushed into the bearing inner race raceway, as preferably, said assembling push rod is plane or inner concave with the external part end that advances push rod and the surface of contact of cylindrical roller.
Further, said inner concave radian is more than or equal to short columnar roller side radian, and helping like this when push rod contacts with roller is the face contact, but not the line contact increases area of contact, guarantees that the roller direction of propulsion does not change, safety and precise send into inner ring raceway.
For the ease of workman's operation, the side of said sleeve column has is convenient to the interior concane gap that bearing inner race takes out.After bearing assembled, the breach of design on sleeve column can make things convenient for workman's bearing of taking, and time saving and energy saving, efficient improves.
The invention has the beneficial effects as follows; The present invention sends cylindrical roller into feeding tube successively through supply disk, utilizes the to-and-fro motion of actuating mechanism controls push rod to promote roller entering bearing inner race raceway simultaneously, has made things convenient for workman's running in bearings roller; Prevented the problem that cost is high, efficient is low and the ultra essential oil film of the roller that collides with easily causes roller surface to scratch that artificial assembling causes simultaneously; Make quality of product significantly improve, efficiency of assembling improves simultaneously, and production capacity also improves thereupon.
