Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing, and in particular to an automatic bearing ball assembly machine. Background Technology

[0002] Bearings are key components in mechanical equipment that support rotating bodies, reduce friction, and ensure rotational accuracy. They are mainly divided into two categories: rolling bearings and sliding bearings. Rolling bearings rely on rolling elements to reduce friction and are suitable for high-speed and medium-to-light load scenarios. Sliding bearings, on the other hand, use oil film lubrication to withstand heavy loads or low-speed conditions. According to the direction of load bearing, bearings can be divided into radial bearings, thrust bearings, and angular contact bearings. Among them, thrust bearings require the balls to be pressed into a ball cage for positioning during the manufacturing process.

[0003] In the existing technology, the ball assembly process of thrust bearings mainly adopts a semi-automated operation mode that combines manual positioning and mechanical pressing. First, the operator manually and accurately places each ball into the positioning area above the ball cage structure. Then, the pressing equipment is started to complete the fixed positioning of the ball. However, the manual positioning operation is slow, which seriously affects the efficiency of large-scale production. In addition, during high-speed continuous operation, there is a risk that the operator's fingers will be accidentally injured by the pressing mechanism.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic bearing ball assembly machine to solve the above-mentioned technical defects.

[0006] The objective of this utility model can be achieved through the following technical solutions:

Symmetrically distributed clamping blocks are also provided above the rotating disk. A positioning and pressing ball mechanism is also provided on one side of the assembly table. The positioning and pressing ball mechanism includes a base plate. An L-plate is slidably connected above the base plate.

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

[0015] This invention uses a steel column hopper to store ball bearings, and gravity causes the ball bearings to fall into the circular groove of the feeding tray. During assembly, the steel ball retainer is placed on the rotating disk. The first lead screw motor drives the bidirectional lead screw to move the clamping block inward synchronously to achieve clamping and fixing. Then, the second lead screw motor drives the ball bearing lead screw to move the L-plate horizontally, so that the opening of the limiting cylinder is aligned with the ball bearing assembly hole of the retainer. Then, the third lead screw motor controls the steel column hopper to descend until the limiting cylinder contacts the surface of the retainer. The second stepper motor drives the feeding tray to rotate and guide the ball bearings into the slide. The ball bearings fall into the limiting cylinder through the slide and enter the assembly hole. The electric push rod pushes the push block to press the ball bearings into place.

[0016] Finally, the stepper motor drives the rotating disk to rotate the cage and switch the assembly hole positions, thereby realizing continuous automated assembly.

[0025] Example 1:

A stepper motor 12 is also fixedly connected to the upper part of the assembly table 1. A spur gear 13 is fixedly connected to the outer side of the drive shaft of the stepper motor 12. The spur gear 13 meshes with the external gear ring 14. A lead screw motor 15 is also fixedly installed inside the rotating disk 11 by bolts. A bidirectional lead screw 16 is fixedly connected to the end of the drive shaft of the lead screw motor 15. A symmetrically distributed clamping block 17 is also provided above the rotating disk 11. A lead screw nut is fixedly connected to the lower part of each clamping block 17. The lead screw nut is threadedly connected to the bidirectional lead screw 16.

[0027] One side of the assembly table 1 is also provided with a positioning ball bearing mechanism 2. The positioning ball bearing mechanism 2 includes a base plate 21, which is placed on the ground. Inside the base plate 21, there is a fixedly connected screw motor 22. At the end of the drive shaft of the screw motor 22, there is a fixedly connected ball screw 23. Above the base plate 21, there is a slidably connected L plate 24. Below the L plate 24, there is a fixedly connected screw nut 2. The screw nut 2 is threadedly connected to the ball screw 23. When the screw motor 22 starts, it drives the ball screw 23 to rotate. The rotation of the ball screw 23 drives the screw nut 2 to move horizontally within the base plate 21, thereby driving the L plate 24 to move synchronously.

[0028] A symmetrically distributed slide rail 25 is fixedly installed on the side of L-plate 24 near assembly table 1. A screw motor 26 is also fixedly installed on the top of L-plate 24 by bolts. The drive shaft of screw motor 26 is fixedly connected to ball screw 27. A slidingly connected mounting block 28 is provided on one side of slide rail 25. A symmetrically distributed slider is fixedly installed on the side of mounting block 28 near L-plate 24. The sliders are all inserted into slide rail 25 and slidably connected to slide rail 25. A screw nut 3 is also fixedly connected on one side of mounting block 28. Screw nut 3 is threadedly connected to ball screw 27. A fixedly connected steel column hopper 29 is provided on one side of mounting block 28.

[0029] A stepper motor 30 is bolted to one side of the lower part of the steel column hopper 29. A rotatably connected feeding plate 31 is also provided inside the lower part of the steel column hopper 29. A circular groove with axial distribution is opened on the outer side of the feeding plate 31. The inside of the circular groove is used to place ball bearings. The drive shaft of the stepper motor 30 is fixedly connected to the shaft at one end of the feeding plate 31. A slide rail 32 is also fixedly connected to one side of the lower part of the steel column hopper 29. A limiting cylinder 33 is fixedly connected to one side of the slide rail 32. The limiting cylinder 33 communicates with the inside of the slide rail 32. An electric push rod 34 is bolted to the top of the limiting cylinder 33. A push block 35 is fixedly installed inside the limiting cylinder 33 by the drive shaft of the electric push rod 34.

[0030] The working process and principle of this utility model are as follows:

[0031] In use, the balls to be assembled are first placed in the steel column hopper 29. At this time, the balls fall into the circular groove on the outside of the feed plate 31 under the action of gravity. When it is necessary to assemble the balls in the ball retainer 18, the ball retainer 18 is first placed above the rotating plate 11. Then the lead screw motor 15 is started. The lead screw motor 15 drives the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 drives the two clamping blocks 17 to move inward synchronously through the lead screw nut 1, thereby limiting and clamping the ball retainer 18 between the clamping blocks 17.

[0032] Then, the second lead screw motor 22 is started. When the second lead screw motor 22 starts, it drives the first ball screw 23 to rotate. The rotation of the first ball screw 23 drives the second lead screw nut to move horizontally within the base plate 21, which in turn drives the L plate 24 to move synchronously until the opening of the limit cylinder 33 coincides with the ball assembly hole on the ball retainer 18. At this time, the third lead screw motor 26 is started. The third lead screw motor 26 drives the second ball screw 27 to rotate. The second ball screw 27 drives the mounting block 28 and the steel column hopper 29 to descend synchronously through the third lead screw nut until the bottom of the limit cylinder 33 contacts the upper end face of the ball retainer 18. Then, the second stepper motor 30 is started. The second stepper motor 30 drives the unloading plate 31 to rotate, thereby moving the balls in the steel column hopper 29 to the top of the slide 32.

[0033] The balls then roll down through the slide rail 32 into the limiting cylinder 33, and finally into the ball assembly hole above the ball retainer 18. Then, the electric push rod 34 is activated, which drives the push block 35 to press down, thereby pressing the balls into the ball retainer 18. Then, the stepper motor 12 is activated, which drives the rotating disk 11 to rotate through the spur gear 13 and the external gear ring 14, thereby driving the ball retainer 18 held above the rotating disk 11 to rotate, and then the ball assembly hole is changed for assembly.
