Description
Technical field
The present invention relates to roller bearing automaton mounting technology field, especially a kind of rack-type cylindrical roller bearing automatic assembly machine.
Background technique
The most widely used automatic assembly machine of bearing industry is ball bearing automatic assembly machine or machine for automatically assembling needle bearing, because bearing need carry out feeding and guiding to rolling element when assembling automatically, the guidance quality of steel ball is good, and the general weight of needle roller is lighter, also feeding easily; But the general slenderness ratio of short columnar roller has certain weight less than 3, and it is relatively more difficult in the feeding process it to be led.How assembling for cylindrical roller bearing at present still is assembled into the master with manual work; Artificial assembling roller cost is high, efficient is low, the ultra essential oil film of the roller that collides with easily causes roller surface to scratch; Easily small dust or greasy dirt are got into bearing inside in the process of assembling; Will cause precise decreasing like this, roller serious wear simultaneously reduces bearing working life; On the other hand, artificial assembling meeting causes fatigue because of workman's long-time operation, possibly cause industrial injury, also is unfavorable for the raising of production capacity simultaneously.
Summary of the invention
The technical problem that the present invention will solve is: low in order to solve the artificial efficiency of assembling of present roller bearing; The technical problem that precision is not high provides a kind of easy to use, the rack-type cylindrical roller bearing automatic assembly machine that can assemble automatically; Realize automated job, improve production capacity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rack-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, a propelling push rod, two two driving gears that sleeve, two tooth bars of stage clip are housed and control two tooth bars actions respectively, and the engagement of driving cog wheel and rack is assembled push rod and advanced push rod one end end to be fixedly connected with two tooth bar ends respectively; Said assembling push rod all is inserted in the stage clip of sleeve with the external part that advances push rod; 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 gear rack transmission control 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.
