Description

Technical Field

[0001] This utility model relates to the field of bearing assembly technology, specifically to a steel ball even distribution device in an automatic assembly system for deep groove ball bearings. Background Technology

[0002] A ball bearing consists of an inner ring, an outer ring, and steel balls, which are evenly distributed within the ball raceways between the inner and outer rings. One step in assembling a ball bearing is to distribute the steel balls, which are sandwiched between the inner and outer ring raceways, into a uniform circumferential distribution. Traditionally, this has been done manually by using a pointed stick to move the steel balls, visually ensuring their even distribution, before pressing a plastic cage into the gaps between the balls. However, manual visual inspection is inaccurate, and the stick-moving method is slow, thus reducing production efficiency and increasing labor intensity.

[0003] Among them, announcement number CN210290516U discloses a ball bearing ball-separating fixture. A central post is located at the center of the base, and ball-separating posts are located around the outer periphery of the central post. The ball-separating posts are evenly distributed around the outer periphery of the central post. The outer diameter of the central post is the same as the inner diameter of the inner ring of the ball bearing. The diameter of the circle formed by the center lines of the multiple ball-separating posts is the same as the diameter of the circle formed by the centers of the multiple steel balls to be placed in the ball bearing. The gap between adjacent ball-separating posts is the same as the diameter of the steel balls, and the number of gaps between adjacent ball-separating posts is the same as the number of steel balls. However, this technical solution still has the following defects:

[0004] In this technical solution, since multiple ball separators are fixedly connected to the base, ball separators can only be used for bearings of a fixed size. When ball separators are used for bearings of different sizes, the entire ball separator fixture needs to be replaced, which is very inconvenient. Utility Model Content

[0005] In view of the problems existing in the ball ball distribution device of the current automatic assembly system for deep groove ball bearings, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a ball bearing equalization device in an automatic assembly system for deep groove ball bearings, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The ball ball equalization device in the automatic assembly system of deep groove ball bearings includes a fixed plate and ball-distributing rods. The surface of the fixed plate has multiple strip-shaped openings arranged in a circular array around the center of the fixed plate. A slider is slidably disposed inside each of the multiple strip-shaped openings. The multiple ball-distributing rods are fixedly sleeved inside the corresponding sliders. The length of the multiple ball-distributing rods increases clockwise. A transmission mechanism is provided on the rear side of the fixed plate to drive the multiple sliders to move.

[0009] Preferably, the transmission mechanism includes a push rod and a threaded rod. The threaded rod is rotatably disposed at the middle of the rear side of the push rod. A movable ring is threadedly sleeved on the rod wall of the threaded rod. Multiple push rods are disposed between the rear side of the corresponding ball-splitting rod and the movable ring. Two first connecting blocks are fixedly disposed at the rear end of the ball-splitting rod. One end of the push rod is rotatably connected to the corresponding first connecting block through a first shaft pin. The other end of the push rod is rotatably sleeved with a second shaft pin. Both ends of the second shaft pin are rotatably connected to second connecting blocks. One side of the second connecting block is fixedly connected to the side wall of the corresponding movable ring.

[0010] Preferably, a rotating wheel is fixedly sleeved at the end of the threaded rod away from the fixed plate.

[0011] Preferably, grooves are provided on both sides of the strip opening, and a limiting block is slidably arranged inside the groove, with one side of the limiting block being fixedly connected to the slider.

[0012] Preferably, the fixing plate is provided with multiple mounting rods at the rear.

[0013] Preferably, the front ends of the plurality of ball-splitting sticks are all provided with bevels.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention utilizes a rotating threaded rod to move a movable ring, which in turn pushes one end of multiple push rods. This causes the push rods to rotate towards being parallel to or perpendicular to the slot, thereby moving multiple sliders. These sliders then move their corresponding ball-separating rods, allowing for adjustment of the spacing between the ball-separating rods. This facilitates the ball-separating of bearings of different specifications. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a ball ball distribution device in an automatic assembly system for deep groove ball bearings.

[0024] Example 1

[0025] Reference Figure 1-3 The ball ball equalization device in the automatic assembly system of deep groove ball bearings includes a fixed plate 1 and ball-distributing rods 4. The surface of the fixed plate 1 has multiple strip-shaped openings 2 arranged in a circular array around the center of the fixed plate 1. Each strip-shaped opening 2 has a slider 3 slidably installed inside it. Each ball-distributing rod 4 is fixedly sleeved inside the corresponding slider 3. Each side of the strip-shaped opening 2 has a groove, and each groove has a limiting block 13 slidably installed inside it. One side of the limiting block 13 is fixedly connected to the slider 3. Multiple mounting rods 14 are fixedly installed at the rear of the fixed plate 1 to facilitate the installation of the fixed plate 1. Each front end of each ball-distributing rod 4 has a bevel, which allows the ball-distributing rod 4 to be smoothly inserted between the balls of the bearing. The length of each ball-distributing rod 4 increases clockwise. A transmission mechanism that drives the multiple sliders 3 to move is provided at the rear of the fixed plate 1.

[0026] Example 2

[0027] Reference Figure 1-3 The transmission mechanism includes a push rod 7 and a threaded rod 11. The threaded rod 11 is rotatably disposed at the middle of the rear side of the push rod 7. A movable ring 10 is threadedly sleeved on the rod wall of the threaded rod 11. Multiple push rods 7 are disposed between the rear side of the corresponding ball-splitting rod 4 and the movable ring 10. Two first connecting blocks 5 are fixedly disposed at the rear end of the ball-splitting rod 4. One end of the push rod 7 is rotatably connected to the corresponding first connecting block 5 through a first shaft pin 6. The other end of the push rod 7 is rotatably sleeved with a second shaft pin 9. Both ends of the second shaft pin 9 are rotatably connected with second connecting blocks 8. One side of the second connecting block 8 is fixedly connected to the side wall of the corresponding movable ring 10. A rotating wheel 12 is fixedly sleeved on the end of the threaded rod 11 away from the fixed plate 1 to facilitate the rotation of the threaded rod 11.

[0028] In this invention, when in use, rotating the threaded rod 11 causes the movable ring 10 to move, which in turn causes the movable ring 10 to push one end of multiple push rods 7, making the multiple push rods 7 rotate towards being parallel to or perpendicular to the strip opening. This causes multiple sliders 3 to move, which in turn causes the sliders 3 to move the corresponding ball-separating rods 4. This allows for adjustment of the spacing between the multiple ball-separating rods 4, thus facilitating the ball-separating of bearings of different specifications.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
