Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, and particularly relates to an automatic bearing outer ring grabbing device. Background Art

[0002] A bearing is an important component in contemporary mechanical structures. Its main function is to support a mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.

[0003] Chinese Patent CN 212580947U discloses a bearing grabbing device. The first double-headed cylinder is installed on a transverse moving mechanism and driven by the transverse moving mechanism to move. The bearing grabbing mechanism is connected to the piston rod in the first double-headed cylinder and driven by the first double-headed cylinder to move up and down. A number of bearing grabbing hands are configured in the bearing grabbing mechanism. The number of bearing grabbing hands grabs and releases the bearings. Every two bearing grabbing hands grab one bearing. However, this bearing grabbing hand is only applicable to the bearings that have completed processing and cannot grab the bearings that have not been press-fitted. Summary of the Utility Model

[0004] In view of the deficiencies of the above-mentioned prior art, the utility model provides an automatic bearing outer ring grabbing device to solve the above technical problems.

A driving motor is installed on the conveying frame, and the output end of the driving motor is connected to a driving roller. The driving roller is connected to a driven roller through a conveyor belt.

[0006] A support column is rotatably sleeved on the support table. The bottom end of the support column is fixedly connected to a gear. A first electric telescopic arm is installed on the bottom surface of the support table. The first electric telescopic arm is fixedly connected to a straight rack, and the straight rack meshes with the gear.

[0007] The top end of the support column is installed with a vertical hydraulic cylinder. The bottom end of the vertical hydraulic cylinder is fixedly connected to a pressing head. The bottom end of the pressing head is fixedly connected to a bearing outer ring holding head. The bearing outer ring holding head is provided with symmetric side cavities.

A second electric telescopic arm is installed on the extension block, and the second electric telescopic arm is fixedly connected to the electromagnetic adsorption plate.

[0008] When the first electric telescopic arm is fully extended, the vertical hydraulic cylinder extends to the first length, and the electromagnetic adsorption plate grabs the bearings to be press-fitted on the conveyor belt. When the first electric telescopic arm is fully retracted, the support column rotates 90°. The vertical hydraulic cylinder extends to the second length, and the bearings to be press-fitted fall to the pressing area of the support table. The vertical hydraulic cylinder extends to the third length to complete the press-fitting.

[0009] Further, the indenter is fixedly connected with symmetric buffer springs, and the bottom ends of the buffer springs are fixedly connected with the bearing outer ring holding heads.

[0010] Further, the support table is equipped with a pressure sensor through an extension column. When the vertical hydraulic cylinder is in a contracted state, the indenter abuts against the pressure sensor to start the drive motor; when the support column rotates 75°, the indenter is separated from the pressure sensor.

[0011] Further, a third electric telescopic arm is installed on the top surface of the support table, and the third electric telescopic arm is fixedly connected with a push plate for pushing the completed pressed bearing away from the pressing area.

[0012] Due to the adoption of the above technical solutions, compared with the prior art, the beneficial effects of the present utility model include:

[0013] 1) The second electric telescopic arm extends, and the electromagnetic adsorption plate clamps and electromagnetically adsorbs the outer ring of the bearing to be pressed, so as to be able to grasp the outer ring and inner ring of the bearing that has not been pressed.
