Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly, and particularly relates to an automatic bearing steel ball assembly device. Background Technique

[0002] A bearing is a part used to support a mechanical shaft to bear rotational motion. It usually consists of an inner ring, an outer ring, rolling elements (steel balls), and a cage, which can reduce friction and support rotational motion, enabling mechanical equipment to operate smoothly. During the production process of bearings, steel balls need to be installed between the bearing outer ring and the bearing inner ring to achieve overall assembly.

[0003] In the prior art, a Chinese patent with the publication number CN113483029A discloses a bearing assembly device, which includes a machine table for transporting the inner ring and the outer ring, and a frame vertically arranged on the machine table. A box body for containing ball bearings is arranged on the frame. A plurality of first holes for the ball bearings to roll down are evenly distributed on the bottom wall of the box body, and the plurality of first holes are all located on the same circumference. A conical cylinder for collecting the ball bearings rolling out of the box body is arranged below the box body. A control mechanism for controlling the quantitative rolling of the ball bearings is arranged between the box body and the conical cylinder. One end of the conical cylinder away from the box body is communicated with a conduit for transporting the ball bearings one by one. The end of the conduit away from the conical cylinder points to the gap between the inner ring and the outer ring on the machine table, ensuring that the number of ball bearings rolling into the gap between the inner ring and the outer ring is consistent with the number of ball bearings required for assembly.

[0004] In the process of using the above device, the steel balls are transported between the bearing outer ring and the bearing inner ring through the conduit to achieve the purpose of assembly. However, in the actual use process, the position where the steel balls are transported to the inner side of the bearing outer ring is relatively concentrated (that is, on one side of the bearing inner ring, because the bearing inner ring needs to be pushed close to the inner wall of the bearing outer ring), resulting in uneven distribution of the overall steel balls. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic bearing steel ball assembly device to solve the problem of uneven distribution of steel balls after assembly proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an automatic bearing steel ball assembly device, including a horizontally placed support base, a steel ball storage box is fixedly installed above the support base, and further includes:

[0007] The upper surface of the front end of the support base is used for placing the bearing outer ring and the bearing inner ring, and the bearing inner ring is located inside the bearing outer ring. A rotating mechanism for driving the bearing inner ring to rotate to evenly disperse the steel balls is arranged inside the support base;

[0008] A horizontally arranged movable plate is arranged below the steel ball storage box, and a lifting structure is formed between the movable plate and the support base through a second cylinder fixedly installed above the movable plate, and a steel ball conveying pipe is connected and installed between the movable plate and the steel ball storage box, and the bottom end of the steel ball conveying pipe corresponds to the position of the outer ring of the bearing;

[0009] The steel ball storage box is provided with a dredging mechanism for dredging the steel balls to avoid blockage.

[0010] Preferably, clamping blocks for fixing the bearing outer ring are arranged on the left and right sides, and a first cylinder fixedly mounted to the support base is fixedly mounted on the side of the clamping block.

[0011] Preferably, an eccentric turntable driven by a motor is rotatably installed below the front end of the movable plate, and a toggle block for pushing the inner ring of the bearing is fixedly installed on the lower surface of the eccentric turntable.

[0012] Preferably, the rotating mechanism comprises a friction disc rotatably mounted on the front upper surface of the support base, and the diameter of the friction disc is smaller than the inner diameter of the bearing outer ring, and the area of ​​the friction disc is larger than the bearing inner ring.

[0013] Preferably, a winding wheel located inside the support base is coaxially fixedly installed below the friction turntable, and a guide wheel is rotatably installed in the middle of the support base.

[0014] Preferably, a connecting rope is wound around the outside of the winding wheel, and the connecting rope passes through the guide wheel and is fixedly installed on the lower surface of the movable plate, and a vortex spring is fixedly installed on the rotating bottom end of the winding wheel.

[0015] Preferably, the dredging mechanism includes a push rod slidably connected to the bottom of the steel ball storage box, and a dredging frame located inside the steel ball storage box is fixedly installed on the top of the push rod, and a reset spring is installed on the outside of the lower end of the push rod to drive it to reset.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the bearing steel ball automatic assembly equipment adopts a new structural design, and its specific contents are as follows:

[0017] 1. The second cylinder drives the movable plate to move downward, so that the steel ball conveying pipe is close to the outer ring of the bearing. Then the eccentric turntable rotates to drive the toggle block to push the inner ring of the bearing to a position close to the inner wall of the outer ring of the bearing. Finally, the steel ball conveying pipe conveys the steel balls between the outer ring and the inner ring of the bearing to achieve the purpose of automatic assembly.

[0018] Further, during the upward movement of the movable plate (i.e., after assembly), the connecting pull drives the winding wheel to rotate, thereby driving the friction turntable to rotate synchronously under the action of the winding wheel. The friction turntable drives the inner ring of the bearing after assembly to rotate, so as to evenly disperse the steel balls after assembly.

[0019] Furthermore, during the downward movement of the movable plate (i.e., at the start of assembly), the friction turntable rotates and resets under the elastic action of the scroll spring, so that the winding wheel rewinds the connecting rope again.

[0020] 2. During the upward movement of the movable plate, it will squeeze the push rod above, so that the push rod drives the dredging frame to move upward inside the steel ball storage box, and the dredging frame is used to stir the steel balls inside the steel ball storage box, so as to achieve the purpose of dredging and avoid blockage.

[0029] Example 1: Please refer to Figures 1 - 3 In order to realize the automatic assembly of the bearing, the present embodiment provides the following technical solutions, which specifically disclose: a horizontally placed support base 1, a steel ball storage box 2 is fixedly installed above the support base 1, the upper surface of the front end of the support base 1 is used to place the bearing outer ring 3 and the bearing inner ring 4, and the bearing inner ring 4 is located on the inner side of the bearing outer ring 3, a horizontally arranged movable plate 7 is arranged below the steel ball storage box 2, the movable plate 7 forms a lifting structure with the support base 1 through a second cylinder 701 fixedly installed above the movable plate 7, and a steel ball conveying pipe 8 is connected and installed between the movable plate 7 and the steel ball storage box 2, and the bottom end of the steel ball conveying pipe 8 corresponds to the position of the bearing outer ring 3, a clamping block 5 for fixing the bearing outer ring 3 is arranged on the left and right sides, and a first cylinder 6 fixedly installed with the support base 1 is fixedly installed on the side of the clamping block 5, an eccentric turntable 9 driven by a motor is rotatably installed below the front end of the movable plate 7, and a toggle block 10 for pushing the bearing inner ring 4 is fixedly installed on the lower surface of the eccentric turntable 9.

[0030] When using the device, first place the bearing outer ring 3 and the bearing inner ring 4 to be assembled at the specified position on the upper surface of the support base 1, then turn on the first cylinder 6 to push the clamping block 5 to move to the middle position, thereby clamping and fixing the bearing outer ring 3. After the fixation is completed, the second cylinder 701 drives the movable plate 7 to move downward, and then the motor drives the eccentric turntable 9 to rotate, and the toggle block 10 on the lower surface of the eccentric turntable 9 is used to push the bearing inner ring 4 to a position close to the inner wall of the bearing outer ring 3. Then, the steel balls in the steel ball storage box 2 are transported to the space between the bearing outer ring 3 and the bearing inner ring 4 through the steel ball conveying pipe 8 to complete the assembly.

[0031] Example 2: Please refer to Figures 4 - 5, in order to solve the problem that the steel balls are unevenly dispersed after the traditional device is assembled, the following technical solution is provided. A rotating mechanism is set up. After the assembly is completed, the rotating mechanism drives the inner ring 4 of the bearing to rotate, so as to evenly disperse the steel balls. Specifically, it is disclosed that: a rotating mechanism for driving the inner ring 4 of the bearing to rotate and evenly disperse the steel balls is arranged inside the support base 1. The rotating mechanism includes a friction turntable 11 rotatably installed on the upper surface of the front end of the support base 1, and the diameter of the friction turntable 11 is smaller than the inner diameter of the outer ring 3 of the bearing, and the area of the friction turntable 11 is larger than that of the inner ring 4 of the bearing. A winding wheel 12 located inside the support base 1 is coaxially and fixedly installed below the friction turntable 11, and a guide wheel 13 is also rotatably installed in the middle inside the support base 1.

[0032] After the assembly is completed, the upward movement of the movable plate 7 drives the connecting pull rope 14 at its bottom end to move synchronously. Thus, under the pulling action of the connecting pull rope 14, the winding wheel 12 drives the friction turntable 11 to rotate. The friction turntable 11 drives the inner ring 4 of the bearing to rotate, so as to evenly disperse the assembled steel balls. After that, the friction turntable 11 rotates and resets under the elastic action of the scroll spring 15, and winds up the connecting pull rope 14 again.

After that, the push rod 16 drives the dredging frame 17 to reset downward under the elastic action of the return spring 18.
