[0024] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] like Figures 1 to 14As shown, this utility model discloses a fully automatic bearing press-fitting machine 100, including a bearing press-fitting machine main unit 101. A robot arm mounting frame 2 and a robot arm 3 are mounted on the upper crossbeam 1 of the main unit. The robot arm is equipped with a guiding device 4. A pair of rear retaining ring stabilizing mechanisms 5 are provided under the upper crossbeam of the main unit. A bearing conveying line 6 is provided on one side of the main unit frame. A bearing flipping device 7 is provided near the end of the bearing conveying line on the frame. A storage rack 8 is provided in front of the flipping device. A rear retaining ring storage rack 9 is provided next to the storage rack. A dialing device 10 is provided on the same side as the bearing conveying line.

[0026] The guiding device consists of a drive cylinder and a guide rail groove pair. This guiding device allows the robot arm to move freely left and right on the upper crossbeam, thereby assembling the bearings at both ends of the wheelset.

[0027] The rear bumper stabilizing mechanism is a lower fork structure, driven by horizontal and vertical small hydraulic cylinders 5.1. Driven by the small hydraulic cylinders, the lower fork can move left, right, up, and down, thereby precisely stabilizing the rear bumper.

[0028] The bearing flipping device 7 has a rectangular support table 7.1, a claw 7.2 on one side of the support table, a V-shaped support plate 7.3 corresponding to the claw, a flipping frame 7.4 under the V-shaped support plate, and a cylinder and a reducer 7.5 connected to the flipping frame; the bearing flips here to facilitate gripping by the robot arm;

[0029] The storage rack 8 has a support 8.1 at its lower part, and at least two V-shaped components 8.2 are provided on the support. Bearings with added rear retaining rings are temporarily stored here.

[0030] The rear retainer storage rack 9 has a base 9.1 at its lower part, and the base is provided with at least three sets of support rods 9.2 for stacking the rear retainers flat.

[0031] The described robotic arm 3 is a robotic arm structure that mimics the human arm and has multiple degrees of freedom. Its front end is equipped with a two-finger gripper 3.1 and a three-jaw chuck 3.2. A pressure roller mechanism 3.3 is located in front of the two-finger gripper, which can evenly roll the rear retaining ring onto the bearing. The two-finger gripper pneumatically clamps the rear retaining ring and pre-fits it onto the axle journal. The three-jaw chuck pneumatically clamps the bearing, transition sleeve, and annular pressure head, etc. It can grip the transition sleeve and fit it onto the piston rod of the main pressure cylinder, grip the bearing and fit it onto the transition sleeve, and grip the annular pressure head for replacement. In short, the robotic arm can meet various gripping requirements for bearing press-fitting.

[0032] The bearing press-fitting process of this utility model is illustrated below.

[0033] like Figure 9 As shown in the front view, top view, and side view, the wheelset pauses at the machine's gear wheel device as it enters the workshop track.

[0034] like Figure 10As shown in the front view, top view, and side view, the bearing rolls into the predetermined position along the conveyor line, and the robot arm picks up the bearing and puts it on the outer transition sleeve of the piston rod of the main pressure cylinder.

[0035] like Figure 11 As shown in the front view, top view, and side view, the gear wheel device moves the wheelset into the center of the machine.

[0036] like Figure 12 As shown in the front view, top view, and side view, the piston rods of the left and right main pressure cylinders extend, pushing the pressure head to fit against the end face of the axle, and the tip enters the tip hole at the axle end to fix the axle.

[0037] like Figure 13 As shown in the front view, top view, and side view, the pressing process begins and is completed.

[0038] like Figure 14 As shown in the front view, top view, and side view, the left and right main pressure cylinders are reset, and the dialing device pulls out the wheelset, waiting for the next pressing operation.

[0039] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
