Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, and in particular to a bearing feeding mechanism. Background Technology

[0002] Stator bearings are critical components in rotating machinery such as electric motors. Their inner rings need to be precisely press-fitted onto designated journals of the stator assembly using an interference fit. This fit requires the bearing to maintain extremely high coaxiality and stability during the pressing process to ensure accurate final installation, uniform force distribution, and to avoid damage to the bearing raceways or stator structure. This is crucial for the smooth operation, noise control, and service life of the motor.

[0003] Traditional stator bearing assembly relies on manual placement of bearings. Operators must repeatedly pick up and place tiny bearings and precisely position them in the stator bearing housing, resulting in high labor intensity and low efficiency. Manual loading is slow, inaccurate, and prone to causing misalignment during pressing, which can damage the stator. Utility Model Content

[0037] This utility model proposes a bearing feeding mechanism.

[0038] In this embodiment of the utility model, such as Figures 1 to 4 As shown, the bearing loading mechanism includes:

[0039] Bin 1, used to hold multiple bearings;

[0040] Conveyor belt 2 is located on the discharge side of the hopper 1, and discharge port 21 is provided at the downstream end of conveyor belt 2. The discharge port 21 is a vertically extending through hole.

[0041] The pushing mechanism 3 is used to push the bearing in the hopper 1 to the conveyor belt 2;

[0042] Material handling mechanism 4 is disposed below the discharge port 21. The material handling mechanism 4 includes a rotatable material handling end 41, which can be rotatably rotated to face directly upward or directly downward.

[0043] The first driving mechanism 5 is used to drive the material taking end 41 to perform a flipping action;

[0044] When the material receiving end 41 is flipped to face directly upward and corresponds vertically with the lower end of the material outlet 21, it can receive the bearing from the material outlet 21;

[0045] When the feed end 41 is flipped to face directly downwards, the bearing can be released.

[0046] Specifically, the conveyor belt 2 is equipped with a guide component 22. The conveyor belt 2 forms a material channel with a width appropriate to the outer diameter of the bearing by cooperating with the inner wall of the guide component 22. The discharge port 21 is located at the end of the material channel. After the bearing is moved out of the hopper 1, it enters the material channel. As the conveyor belt 2 rotates, the bearing moves along the material channel toward the discharge port 21. The upper end of the discharge port 21 is the inlet and the lower end is the outlet. The bearings enter the discharge port 21 one by one from the inlet.

[0047] Specifically, an adjusting component 23 is detachably fixed in the material channel, which can be used to adjust the width of the material channel to accommodate bearings of different sizes and specifications.

[0048] Specifically, the bearing can enter the discharge port 21 naturally during the process of movement, or it can be driven into the discharge port 21 by a matching structure.

[0049] To accommodate the structure, a magnet 24 is provided at the inlet position of the discharge port 21, and a pressure needle 25 is movably provided above the conveyor belt 2 at a position opposite to the inlet of the discharge port 21. The pressure needle 25 is driven by a cylinder or a linear motor to move vertically to insert into or retract from the discharge port 21.

[0050] When the bearing travels to the inlet near the outlet 21, it is attracted by the magnet 24 and suspended at the inlet of the outlet 21. The magnet 24 is pressed into the outlet 21 by the downward movement of the pressure needle 25, thereby achieving the effect of the bearing entering the outlet 21 one by one.

[0051] Specifically, the discharge method of hopper 1 can refer to existing technology, or adopt the following embodiments:

[0052] The pushing mechanism 3 includes a pushing component 31. The hopper 1 is provided with at least one vertically extending trough 11. The trough 11 is used to accommodate multiple vertically stacked bearings. The lower end of the trough 11 has a communicating front opening and a rear opening. The pushing component 31 is used to horizontally insert into the rear opening and push the bottom bearing forward so that it enters the conveyor belt 2 from the front opening.

[0053] When the pusher 31 exits the opening, the upper bearing automatically falls to the bottom of the material trough 11 due to gravity.

[0054] The pusher 31 is connected to a cylinder or a linear motor. When the pusher 31 moves to the end of its stroke, the front end of the pusher 31 is flush with the outer edge of the front opening.

[0055] Specifically, the hopper 1 is provided with multiple parallel material troughs 11, and each material trough 11 is provided with an independent pusher 31.

[0056] Specifically, the material handling mechanism 4 also includes a release mechanism, which includes a pin 61 and a driver 62;

[0057] The material receiving end 41 is provided with a material hole 42 for accommodating the bearing, and the inner wall of the material hole 42 is provided with a magnetic suction element 43 for adsorbing the bearing.

[0058] The ejector pin 61 can be inserted into the material hole 42. The driver 62 is used to drive the ejector pin 61 to move axially along the material hole 42, so as to drive the bearing to disengage from the magnetic suction member 43 and form a bearing release action.

[0059] Specifically, the driver 62 is a cylinder or a linear motor.

[0060] Specifically, the material handling mechanism 4 also includes a first support 44 and a second support 45. The second support 45 is pivotally mounted on the first support 44 via a rotating shaft. The material handling end 41 and the release mechanism are located on the second support 45.

[0061] The first drive mechanism 5 includes a gear, a rack, and an actuator. The gear is fixedly sleeved on the rotating shaft, and the rack is connected to the actuator and meshes with the gear.

[0062] When the actuator drives the rack to move, it drives the gear to rotate, thereby driving the second support 45 to rotate and realizing the flipping action of the material picking end 41.

[0063] Specifically, the actuator is a cylinder or a linear motor.

[0064] Specifically, the feed hole 42 is provided with a vertically extending positioning pin 46.

[0065] When the bearing falls into the material hole 42, the inner ring of the bearing is movably sleeved on the positioning pin 46.

[0066] Specifically, it also includes a linear drive module 7, which drives the material handling mechanism 4 to perform linear motion, so as to drive the material handling end 41 to move between positions that are vertically opposite and offset from the material outlet 21.

[0067] When the material receiving end 41 is vertically aligned with the material outlet 21, it can receive the bearing from the material outlet 21. After receiving the bearing, the material receiving end 41 can be moved to a position offset from the material outlet 21 by the linear drive module 7, for example, after moving to the release station, it can be flipped to face directly downwards and the bearing can be released to the predetermined position.

[0068] Specifically, sensors can be installed at various locations in this utility model as needed to sense the state of each location, such as whether the bearing is at the discharge port 21 or whether the pusher 31 is at the trough 11.

[0069] This invention achieves precise bearing transfer within a compact space through a flip-up material handling mechanism. The bearings are fed and transported via a hopper and conveyor belt. The flip-up material handling end receives the bearings from an upward-facing position, aligned vertically with the discharge port, and then flips downwards to release them. This eliminates manual intervention, significantly improving feeding speed and positioning efficiency, and effectively reducing the failure rate of press-fitting. The trajectory movement avoids interference from internal piping, increasing space utilization. The modular structure reduces maintenance frequency and labor costs.

[0070] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
