Description

Technical Field

[0001] The present application relates to the field of bearing processing, and in particular to an automatic assembly device for rolling bearings. Background Art

[0002] A ball bearing is a precision mechanical component that converts the sliding friction between a running shaft and a shaft seat into rolling friction, thereby reducing friction losses.

[0003] In the prior art, a ball bearing generally includes an inner ring, an outer ring and a ball. The ball is arranged between the inner ring and the outer ring to reduce the friction between the inner ring and the outer ring. The ball generally needs to be filled with oil to further reduce the friction between the ball and the outer ring and between the ball and the inner ring, and a dust cover is added after the oil is filled to reduce the influence of the outside world on the ball. Generally, the oil is filled through an oil filling device, which is connected to an oil tank and an oil pump. The oil is pumped out of the oil tank through the oil pump and injected into the bearing through the oil filling device.

[0004] Oil is generally added between the inner ring and the outer ring through an oil filling device. When adding oil, the balls tend to roll between the inner ring and the outer ring along with the oil filling device, causing the oil to be added in the same place, resulting in uneven oil filling, which in turn leads to increased wear of the balls.

[0092] Working principle:

[0093] 1. Under the joint action of the transverse push cylinder 62 and the longitudinal push cylinder 65, the push plate 67 drives the bearings on the stage 31 to enter the oil filling position one by one;

[0094] 2. After the bearing enters the oil filling position, the electric push rod 51 extends to make the rotating block 52 press the screw rod 42, thereby driving the outer ring clamping strip 41 and the inner ring clamping strip 45 to extend out of the mounting cavity 342 through the sliding groove 341 and out of the surface of the turntable 34;

[0095] 3. The clamping motor 47 drives the auxiliary wheel 48 to rotate forward, thereby driving the auxiliary wheel 46 and the active bevel gear 44 to rotate synchronously, and the active bevel gear 44 drives the passive bevel gear 43 and the screw rod 42 to rotate forward synchronously, thereby driving the outer ring clamping strip 41 and the inner ring clamping strip 45 to approach each other until the outer ring clamping block presses against the outer ring of the bearing, and the inner ring clamping block presses against the inner ring of the bearing, thereby clamping and fixing the bearing;

[0096] 4. The rotating motor 32 drives the rotating shaft 33 and then drives the rotating disk 34 to rotate. While the rotating disk 34 rotates, the oil injection device 2 outputs oil to the bearing and the air blowing port 21 blows air toward the bearing to accelerate the penetration of the oil;

[0097] 5. After the turntable 34 rotates one circle, the oil injection device 2 stops outputting oil and the air outlet 21 stops blowing air, and the rotating motor 32 drives the auxiliary driving wheel 48 to rotate in the opposite direction, thereby driving the auxiliary wheel 46 and the driving bevel gear 44 to rotate synchronously, and the driving bevel gear 44 drives the driven bevel gear 43 and the screw rod 42 to rotate in the opposite direction synchronously, thereby driving the outer ring clamping strip 41 and the inner ring clamping strip 45 to move away from each other and thus loosen the bearing;

[0098] 6. The electric push rod 51 retracts to allow the rotating block 52 to press against the screw rod 42, thereby driving the outer ring clamping strip 41 and the inner ring clamping strip 45 to pass through the sliding groove 341 and enter the installation cavity 342;

[0099] 7. Under the joint action of the transverse pushing cylinder 62 and the longitudinal pushing cylinder 65, the pushing plate 67 drives the bearing on the oil filling position to leave the oil filling position and drives the bearing on the stage 31 to enter the oil filling position.

[0100] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
