Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to an exchangeable double-station feeding mechanism. Background Art

[0002] A cage (also called a bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guide the rolling elements and keep them in the bearing.

[0003] The existing bearing cage feeding mechanism (publication number: CN216154887U) has at least the following disadvantages:

[0004] When the above patent is in use, the retaining frame is pushed into the specified assembly position by the electric push rod, and then the retaining frame is fixed to the bearing assembly. Since the retaining frame is stacked together from top to bottom and sleeved on the outer surface of the guide column, when the guide column moves back and forth alternately, the guide column itself will shake. When the bottom retaining frame is assembled, the upper guide column and retaining frame are not fixed, which will cause the bottom retaining frame to fail to fall into the specified position correctly, affecting the assembly accuracy of the retaining frame.

Through this device, a retaining rack above the retaining rack to be assembled can be fixed, and the mounting rack can be fixed at the same time as the retaining rack is fixed, so that the retaining rack to be assembled can accurately fall into the bearing, which is convenient for subsequent assembly and ensures the assembly accuracy.

[0008] As a further solution of the utility model, the bottom end of the first connecting rod is rotatably mounted on the outer surface of one end of the sliding rod, and the bottom end of the second connecting rod is rotatably mounted on the other end of the sliding rod.

[0010] As a further solution of the utility model, the two clamping plates are made of rubber material, and the retaining frame is prevented from being pinched by the elastic deformation of the rubber material.
