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 the timing of bearing automatic mounting need to be carried out feeding and guiding to rolling element, the guidance quality of steel ball is good, and the general weight of needle roller is lighter, also easily feeding; But the general slenderness ratio of short columnar roller is less than 3, and certain weight is arranged, and in feeding process, it is led more difficult.For the assembling of cylindrical roller bearing, how still take manual assembly as main at present, manual assembly roller cost is high, efficiency is low, the superfinishing oil film of the roller that easily collides with causes roller surface to scratch, easily small dust or greasy dirt are entered to bearing inside in the process of assembling, will cause precise decreasing like this, roller serious wear simultaneously, reduce bearing working life; On the other hand, manual assembly can cause fatigue because of workman's long-time operation, may cause industrial injury, also is unfavorable for the raising of production capacity simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is: low in order to solve current roller bearing manual assembly efficiency, the technical problem that precision is not high, provide a kind of easy to use, the rack-type cylindrical roller bearing automatic assembly machine that can automatically assemble, 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 arranged on table top, comprise supply disk, the cylindrical roller assemble mechanism, assembling mould and electric control box, described cylindrical roller assemble mechanism comprises an assembling push rod, one advances push rod, two sleeves that stage clip is housed, two tooth bars and control respectively two driving gears of two tooth bars action, the engagement of driving cog wheel and rack, the assembling push rod is fixedly connected with two tooth bar ends respectively with propelling push rod one end end, the external part of described assembling push rod and propelling push rod all is inserted in the stage clip of sleeve, described assembling mould comprises that die holder and one are connected to the broken ring of die holder upper surface, described broken ring and die holder form one be used to placing the cavity of bearing inner race, the feeding tube outlet port of described supply disk has positioning pipe, the positioning pipe outlet end is fixedly connected on the broken ring opening, the bottom of described positioning pipe has is convenient to the opening slot that cylindrical roller passes through, the opening of the broken ring on described opening slot and die holder aligns, the external part of described assembling push rod is over against opening slot, advance push rod and the angled setting of assembling push rod, advance the external part of push rod towards the broken ring direction and higher than the broken ring setting.
In order effectively to fix bearing inner race, facilitate roller assembling, described cavity to comprise out that the circular groove bottom is fixedly connected with sleeve column at the circular groove of die holder upper surface with for the sleeve column of rigid bearing inner ring, described 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, described assembling push rod becomes 40 ° ~ 41 ° angles with the propelling push rod.Select such angle, can guarantee to advance push rod can not push up bearing inner race when advancing, cause the problem scratched, advance simultaneously push rod to promote roller in inner ring raceway, advance Shi Buhui and broken ring interference, 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, described assembling push rod and to advance the external part end of push rod and the surface of contact of cylindrical roller be plane or inner concave.
Further, described inner concave radian is more than or equal to short columnar roller side radian, and being conducive to like this when push rod contacts with roller is 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 described sleeve column has is convenient to the interior concane gap that bearing inner race takes out.When bearing assemble well after, the breach of design on sleeve column can facilitate workman's bearing of taking, time saving and energy saving, efficiency improves.
The invention has the beneficial effects as follows, the present invention sends cylindrical roller into feeding tube successively by supply disk, the to-and-fro motion that utilizes simultaneously the gear rack transmission to control push rod promotes roller and enters the bearing inner race raceway, facilitated workman's running in bearings roller, prevented simultaneously the problem that cost is high, efficiency is low and the superfinishing oil film of the roller that easily collides with causes roller surface to scratch that manual assembly causes, make quality of product significantly improve, efficiency of assembling improves simultaneously, and production capacity also improves thereupon.
