Abstract

The invention discloses an automatic assembly machine for rack type short cylindrical roller bearings, which comprises a supply disc, a cylindrical roller assembly mechanism, an assembly mold and an electric cabinet. The cylindrical roller assembly mechanism comprises an assembly push rod, a propelling push rod, two sleeves, two racks and two transmission gears, the two sleeves are provided with pressure springs, the two transmission gears respectively control actions of the two racks and are meshed with the racks, one end of the assembly push rod and one end of the propelling push rod are respectively fixedly connected with the ends of the two racks, both an extending end of the assembly push rod and an extending end of the propelling push rod are inserted in the pressure springs of the sleeves, and the propelling push rod and the assembly push rod are angularly arranged on one side of the assembly mold. Gear and rack transmission is used for controlling reciprocating motion of the push rods so as to push rollers to enter a bearing inner raceway, so that the bearing rollers are assembled by workers conveniently, problems that cost is high, efficiency is low, and super-finishing oil films easy to be collided with the rollers scratch the surfaces of the rollers in manual assembly are prevented, and the quality of products is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automatic assembly of roller bearings, in particular to an automatic assembly machine for rack-type short cylindrical roller bearings. Background technique [0002] The most widely used automatic assembly machine in the bearing industry is the automatic assembly machine for ball bearings or the automatic assembly machine for needle roller bearings, because the rolling elements need to be fed and guided during the automatic assembly of bearings, the steel balls have good guidance, and the needle rollers are generally lighter in weight , It is also easy to feed; but short cylindrical rollers generally have a length-to-diameter ratio of less than 3, have a certain weight, and it is difficult to guide them during the feeding process. At present, most of the assembly of short cylindrical roller bearings is still manual assembly. Manual assembly of rollers is costly and inefficient, and it is easy to bump the u...
