Technical Field

[0001] The invention relates to the technical field of bearing assembly, and in particular to an automatic bearing assembly device. Background Art

[0002] With the advancement of mechanization, bearings are used more and more widely. They are widely used in the matching of various shaft parts. Bearings are generally composed of an outer ring, an inner ring and the balls between them. Therefore, they often need to be assembled during the processing.

[0003] The automatic bearing assembly machine with patent publication number CN117145878A manually loads and unloads the inner and outer rings of the bearings, which has low working efficiency. When cleaning the inner and outer rings of the bearings, it is impossible to rotate and clean along the outer wall of the inner ring and the inner wall of the outer ring of the bearing.

[0004] When the automatic bearing assembly machine fills the bearing with balls, it is necessary to position and limit the inner and outer rings of the bearing in advance. The diameters of the inner and outer rings of different bearings are different, so flexible adjustments are required according to actual conditions. The existing automatic bearing assembly machine assembles bearings of a single specification and has certain limitations in actual use. At the same time, the outer ring of the bearing is limited by the baffle on the frame.

[0021] Step 1: The outer ring of the bearing is conveyed on the first conveyor belt, and the inner ring of the bearing is conveyed on the second conveyor belt. The outer ring of the bearing is conveyed to the first feeding position, and the inner ring of the bearing is conveyed to the second feeding position. The second pneumatic cylinder drives the second pusher to move, and then pushes the outer ring of the bearing to the assembly position. The third pneumatic cylinder drives the third pusher to move, and then pushes the inner ring of the bearing to the assembly position, and the inner ring of the bearing is located inside the outer ring of the bearing. At this time, the first pneumatic cylinder drives the first pusher to move, and pushes the outer ring and the inner ring of the bearing to the first station;

[0022] Step 2: The material moving plate is driven to move by the fifth pneumatic cylinder, and the material moving groove of the material moving plate is clamped on the outer side of the bearing outer ring. At this time, the translation seat is driven to move by the fourth pneumatic cylinder, thereby realizing the translation of the material moving plate. Then the fifth pneumatic cylinder contracts, and the material moving plate is separated from the bearing outer ring. The operation is repeated, and the bearing outer ring and the bearing inner ring move forward in the first station, the second station, and the third station in turn.

[0023] Step 3: The sixth pneumatic cylinder drives the motor frame and the turntable to move downward until the dust suction pipe is inserted between the outer ring of the bearing and the inner ring of the bearing. At this time, the first motor drives the turntable to rotate, and the dust suction pipe rotates between the outer ring of the bearing and the inner ring of the bearing. At the same time, the dust suction fan works, and the dust suction pipe sucks out the dust between the inner wall of the outer ring of the bearing and the outer wall of the inner ring of the bearing, so as to clean the outer ring of the bearing and the inner ring of the bearing;

[0024] Step 4: The seventh pneumatic cylinder is operated to drive the fixed plate to move upward.

The limit column on the slider moves in the first adjusting groove and contacts the outer ring of the bearing for limiting position. The third motor is operated to drive the threaded rod to rotate, thereby driving the threaded limit block to move in the second adjusting groove, pushing the inner ring of the bearing to move and contact the inner wall of the outer ring of the bearing. At this time, it is used for filling and installation of balls. After filling, the limit column is separated from the outer ring of the bearing and moves downward, and the limit block is separated from the inner ring of the bearing and moves downward. Then the filled bearing is moved to the third station for the bearing ball separation operation.

[0025] The beneficial effects of the present invention are as follows: the outer ring and the inner ring of the bearing are automatically loaded at the first feeding position and the second feeding position respectively, and the outer ring and the inner ring of the bearing are assembled at the assembly position, and then the bearing is moved and loaded in an orderly manner between the first station, the second station and the third station through the material transfer device, with a high degree of automation;
