Description

Technical Field

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

[0002] A contact ball bearing is a type of rolling bearing that can withstand both radial and axial loads simultaneously. Its core structure consists of spherical balls mounted between an inner and an outer steel ring.

[0003] Most existing bearings are assembled manually. During the assembly of the ball bearings, factors such as the operator's skill level, attention, and fatigue can easily lead to deviations or omissions in the placement of the ball bearings, thus affecting the quality and reliability of the bearings. In addition, manual counting and placement of the ball bearings is not only inefficient but also prone to human error, increasing production costs and potentially affecting product quality. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a contact ball bearing assembly mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A contact ball bearing assembly mechanism includes a base and a support frame with a conveyor belt mounted on top. A connecting frame is fixedly connected to the upper surface of the support frame, and a slide is movably connected to the connecting frame. A power component for driving the slide to move up and down is provided on the upper surface of the connecting frame. One end of the slide passes through the connecting frame and is fixedly connected to a storage box. A discharge pipe is fixedly connected to the bottom of the storage box, and a discharge box is fixedly connected to the bottom end of the discharge pipe. A U-shaped block is fixedly connected to the outer circumference of the discharge pipe. Damping return springs are fixedly connected to both ends of the U-shaped block, and an insert is fixedly connected between the damping return springs. A connecting block is fixedly connected to one side of the connecting frame, and the discharge port of the discharge box contacts the connecting block. An inclined plate is fixedly connected to the top of the connecting block. A clearance groove is opened on the insert, and the inclined plate can pass through the clearance groove. An insertion port is opened on one side of the discharge pipe, and the insert passes through the insertion port and contacts the inner wall of the discharge pipe.

[0007] As a further embodiment of this utility model, the power assembly includes a fixed frame, which is fixed to the top of the connecting frame by bolts. An electric push rod is fixedly connected to the upper surface of the fixed frame, and the extended end of the electric push rod passes through the fixed frame and is fixed to the slide.

[0008] As a further embodiment of this utility model, one end of the carriage passes through the connecting frame and is fixedly connected to a U-shaped frame, and both ends of the U-shaped frame are fixedly connected to positioning blocks.

[0009] As a further embodiment of this utility model, a cylinder is fixedly connected in the groove at the top of the base, and a limit block is fixedly connected to one end of the cylinder piston rod. The conveyor belt of the conveyor belt has multiple slots, and the limit block can pass through the slots at the corresponding positions.

[0010] As a further embodiment of this utility model, both ends of the U-shaped block are fixedly connected to telescopic columns, and the telescopic columns are fixed to the insert block, and the damping reset spring is sleeved on the outside of the telescopic columns.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the combination of inclined plate and insert block enables the material storage box to be fed and discharged through the discharge pipe during the up and down movement of the material storage box, thereby realizing the separation and positioning of the ball bearings and improving the efficiency of the device.

[0016] 2. In this utility model, not only can the position of the bearing inner ring be assisted to swing after the ball is placed by setting the limiting block, but the positioning block can also prevent the bearing inner ring from moving upward during the straightening process, thereby improving the positioning effect of the device.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0025] Reference Figures 1-5 A contact ball bearing assembly mechanism includes a base 4 and a support frame 5 on which a conveyor belt 3 is mounted, the support frame 5 being fixed to the upper surface of the base 4.

[0026] The upper surface of the support frame 5 is fixed with two baffles 9 by bolts, and the conveyor belt 3 is located between the two baffles 9. The baffles 9 can block and restrict the position of the bearing on the conveyor belt 3.

[0027] like Figure 1 As shown, a connecting frame 6 is fixed to the upper surface of the support frame 5 by bolts, and a slide 13 is slidably connected to the connecting frame 6. The upper surface of the connecting frame 6 is provided with a power component that drives the slide 13 to move up and down. The power component includes a fixed frame 1, which is fixed to the top of the connecting frame 6 by bolts. An electric push rod 7 is fixed to the upper surface of the fixed frame 1 by bolts. The extended end of the electric push rod 7 passes through the fixed frame 1 and is fixed to the slide 13.

[0028] One end of the slide 13 passes through the connecting frame 6 and is fixed to the storage box 2 by bolts. The bottom of the storage box 2 is connected to and fixed to the discharge pipe 19. The diameter range inside the discharge pipe 19 can accommodate a ball bearing. The bottom end of the discharge pipe 19 is connected to and fixed to the discharge box 20.

[0029] like Figure 5 As shown, a U-shaped block 22 is fixed to the outer circumference of the discharge pipe 19 by bolts. Damping return springs 23 are welded to both ends of the U-shaped block 22. Insert blocks 21 are welded between the damping return springs 23. Telescopic columns 24 are fixed to both ends of the U-shaped block 22 by bolts.

[0030] In this utility model, a sloping plate 18 is welded to the top of the connecting block 12. The sloping plate 18 is inclined downwards. A clearance groove is provided on the insert block 21. A slope is provided in the clearance groove. The sloping plate 18 can pass through the clearance groove and contact the slope. A socket is provided on one side of the discharge pipe 19. The insert block 21 passes through the socket and contacts the inner wall of the discharge pipe 19.

[0031] The telescopic column 24 is fixed to the insert block 21, and the damping return spring 23 is sleeved on the outside of the telescopic column 24. The telescopic column 24 can guide the insert block 21 and prevent the insert block 21 from tilting during the movement.

[0032] A connecting block 12 is fixed to one side of the connecting frame 6 by bolts, and the discharge port of the discharge box 20 is in contact with the connecting block 12;

[0033] The electric push rod 7 retracts, causing the slide 13 to move the storage box 2 upward, which in turn causes the discharge pipe 19 to move the U-shaped block 22 upward. When the insertion block 21 moves upward with the discharge pipe 19, it slowly gets out of the squeezing force of the inclined plate 18, causing the insertion block 21 to move outward along the insertion port. At this time, the damping return spring 23 returns to its original position, and the telescopic column 24 extends. When the insertion block 21 rises to its maximum height, the discharge pipe 19 is no longer blocked by the insertion block 21, and the balls in the storage box 2 enter the discharge box 20 through the discharge pipe 19.

[0034] As the discharge pipe 19 moves upward, the discharge box 20 moves upward and contacts the connecting block 12, and the connecting block 12 blocks the discharge port of the discharge box 20.

[0035] Extend the electric push rod 7 to move the discharge tube 19 downward. During the descent, the insert block 21 is squeezed by the inclined plate 18 and begins to gradually move into the discharge tube 19 until the insert block 21 reaches the bottom of the inclined plate 18. The damping return spring 23 is squeezed. At this time, the insert block 21 restricts the ball located at the top of the insert block 21 in the discharge box 20, separating it from the ball located at the bottom of the insert block 21 in the discharge box 20.

[0036] As the discharge pipe 19 moves downward, the discharge box 20 separates from the connecting block 12. At this time, the discharge port of the discharge box 20 is no longer blocked, allowing the rollers located at the bottom of the insert block 21 inside the discharge box 20 to fall into the space between the inner and outer rings of the bearing. This cycle repeats to achieve quantitative feeding.

[0037] It should be noted that one end of the slide 13 passes through the connecting frame 6 and is fixed with a U-shaped frame 8 by bolts. Both ends of the U-shaped frame 8 are welded with positioning blocks 17. At the same time, the slide 13 moves downward, causing the U-shaped frame 8 to drive the positioning blocks 17 to move downward, so that they contact the upper surface of the bearing inner ring, thereby preventing the bearing inner ring from moving upward during the alignment process.

[0038] A cylinder 11 is fixed in the groove at the top of the base 4 by bolts. One end of the piston rod of the cylinder 11 is fixed with a limit block 16 by bolts. The conveyor belt of the conveyor belt 3 has multiple slots 14, and the limit block 16 can pass through the slots 14 at the corresponding positions. The cylinder 11 extends to allow the limit block 16 to pass through the slots 14, thereby allowing the limit block 16 to further align the position of the bearing inner ring.

[0039] The piston rod of cylinder 11 is fixed with a sliding rod by bolts, and the sliding rod is fixed to the bottom of the limiting block 16. Two guide rods 10 are fixed in the groove at the top of the base 4 by bolts, and the sliding rod slides along the guide rods 10. The guide rods 10 can guide the sliding rod to prevent it from tilting during movement, so that the limiting block 16 can move stably.

[0040] Working principle: The conveyor belt 3 transports the placed bearings to be processed and places the slot 14 inside the bearing. Ball bearings are added into the storage box 2. When it is necessary to install the ball bearings, the electric push rod 7 is activated first. The electric push rod 7 retracts, causing the slide 13 to move the storage box 2 upward, thereby causing the discharge pipe 19 to move the U-shaped block 22 upward. At this time, the insert block 21 moves upward and begins to get rid of the squeezing force of the inclined plate 18. The damping return spring 23 returns to its original position, and the telescopic column 24 extends, thereby causing the insert block 21 to move outward along the insertion port. At the same time as it moves, the connecting block 12 blocks the discharge port of the discharge box 20 until the discharge pipe 19 moves to the highest point. At this time, the discharge pipe 19 is not blocked by the insert block 21, and the discharge pipe 19 does not affect the discharge. The discharge port of the discharge box 20 is also completely blocked.

[0041] At this time, the balls inside the storage box 2 enter the discharge box 20 through the discharge pipe 19 and cannot roll out;

[0042] Then the electric push rod 7 extends, causing the discharge pipe 19 to move downwards. The insert block 21 begins to receive the squeezing force of the inclined plate 18, and the damping return spring 23 is compressed, thereby causing the insert block 21 to be reinserted into the discharge pipe 19. At the same time, the connecting block 12 begins to leave the discharge box 20, releasing the obstruction.

[0043] At this time, the insert 21, which is gradually squeezed back into the discharge pipe 19, separates the balls in the discharge pipe 19;

[0044] As the discharge pipe 19 continues to move downward, the discharge box 20 is completely separated from the connecting block 12. At this time, the discharge port of the discharge box 20 is no longer blocked, and the roller located at the bottom of the insert block 21 inside the discharge box 20 falls into the space between the inner and outer rings of the bearing through the discharge port.

[0045] The conveyor belt 3 continues to convey the bearing after the ball bearings are added to the bottom of the U-shaped frame 8 and then stops. The cylinder 11 is activated and extends so that the limiting block 16 passes through the slot 14, thereby further aligning the position of the bearing inner ring. At the same time, the slide 13 moves downward so that the U-shaped frame 8 drives the positioning block 17 to move downward so that it contacts the upper surface of the bearing inner ring, thereby preventing the bearing inner ring from moving upward during the alignment process.
