Description

Technical Field

[0001] This utility model relates to the field of bearing retainer mounting technology, specifically to an automatic bearing retainer mounting device. Background Technology

[0002] In the bearing manufacturing industry, the bearing cage mounting process is one of the key steps. The bearing cage plays an important role in fixing and guiding the bearing balls in the bearing. The mounting quality directly affects the overall performance and service life of the bearing. The traditional manual mounting method is not only labor-intensive and inefficient, but also difficult to guarantee mounting accuracy. Problems such as loose mounting and positional deviation are prone to occur, which can cause noise and vibration during bearing operation, and even cause failures. It cannot meet the needs of large-scale, high-quality bearing production.

[0003] Although some automated bearing retainer mounting devices have appeared on the market, most of these devices are complex in structure and inconvenient to operate. Some devices are not precise enough in positioning the bearing retainer during the mounting process, resulting in deviations in the mounting position. This prevents the connecting pins from accurately entering the through holes of the bearing retainer, affecting the assembly quality of the bearing. In addition, it is necessary to move the pins to another location to press and fix them in place, which is troublesome and reduces production efficiency. To address these issues, we propose an automated bearing retainer mounting device. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 An automatic bearing retainer mounting device includes a support base 1. In use, the support base 1 is first placed stably in a suitable working position to ensure stability. The support base 1 is circular and hollow. Inside its hollow shape, a servo motor 16 is fixedly mounted via a mounting plate 17. The servo motor 16 is started, and its output end passes through the support plate 3 and is fixedly connected to the center of the bottom surface of a rotating plate 5, thereby driving the rotating plate 5 to rotate on top of the support plate 3. Multiple support blocks 4 are evenly installed in multiple placement slots evenly opened on the top surface of the rotating plate 5. Then, the lower bearing retainer 12 is placed on the support block 4, and the bearing is placed into the placement slot. Finally, the upper bearing retainer 13 is placed above the bearing balls.

[0019] On the right side of the top surface of the support plate 3, a first support frame 8 and a second support frame 9 are fixedly installed. The side wall of the second support frame 9 near the rotating plate 5 has a groove, and a slider with a T-shaped cross-section is placed in the groove. The outer wall of the slider is fixedly connected to one side of the lifting plate 10, so that the lifting plate 10 can slide on the side wall of the second support frame 9. A positioning ring 14 is fixedly installed on the left side of the bottom surface of the lifting plate 10 through a mounting bracket 15. The slot at the bottom of the positioning ring 14 matches the upper bearing retainer 13, which can position the upper bearing retainer 13. A through hole corresponding to the mounting hole of the bearing retainer is opened on the positioning ring 14. A guide tube is fixedly installed in the through hole. A guide nail hose 6 is placed in a plurality of through holes evenly opened on the second support frame 9. One end of the guide nail hose 6 is fixedly connected to the top of the guide tube, and the other end is connected to the output end of the nail feeding machine.

[0020] When the rotating plate 5 rotates to rotate the placement slot containing the bearing retainer to the appropriate position, the second hydraulic rod 11, which is fixedly installed on the right side of the top surface of the support plate 3, is activated. The output end of the second hydraulic rod 11 is fixedly connected to one side of the bottom surface of the lifting plate 10. The second hydraulic rod 11 pushes the lifting plate 10 down, causing the positioning ring 14 to descend, so that the positioning ring 14 locks the upper bearing retainer 13. At this time, the nail feeding machine transports the nails connected to the bearing retainer through the guide nail hose 6 and the guide cylinder to the top of the mounting hole of the bearing retainer, and falls into the mounting hole of the bearing retainer, completing the nailing operation.

[0021] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 Similarly, first place the support base 1, turn on the servo motor 16 to drive the rotating plate 5 to rotate. When the placement slot on the rotating plate 5 rotates to the nailing position, the bearing retainer can be nailed by the nail feeder, the guide hose 6 and the positioning ring 14. After that, the nailed bearing retainer can be rotated to the pressing position, that is, the first support frame 8. The first hydraulic rod 7 can be activated. The output end of the first hydraulic rod 7 can drive the pressing plate to descend. Under the action of the extrusion block and the support block 4 installed at the bottom of the pressing plate, the nails can be pressed and fixed. The second support frame 9 and the lifting plate 10 are slidably connected by the sliding groove and the slider. However, in some special cases, the sliding of the lifting plate 10 can be made smoother by adding lubricating oil in the sliding groove, so that the positioning ring 14 can accurately descend and lock the upper bearing retainer 13. The heat dissipation mesh plate 2 installed on the support base 1 can dissipate heat from the servo motor 16.

[0022] During the nail guiding process, if it is found that the nail is not being fed smoothly in the nail guide hose 6, check whether the connection between the nail feeding machine and the nail guide hose 6 is tight, and whether the nail guide hose 6 is bent or blocked. If there is a problem, adjust the output parameters of the nail feeding machine or straighten the nail guide hose 6 in time to ensure that the nail can pass smoothly through the nail guide hose 6 and the guide cylinder to reach the designated position. When the pressing plate squeezes the nail for nailing, the pushing speed and force of the first hydraulic rod 7 can be adjusted appropriately according to the material of the bearing retainer and the nailing requirements to improve the nailing quality. For example, for the bearing retainer with a softer material, the pushing speed and force of the first hydraulic rod 7 can be reduced to avoid excessive squeezing and damage to the bearing retainer. For the bearing retainer with high nailing requirements, the pushing parameters of the first hydraulic rod 7 can be precisely controlled to ensure the nailing depth and position accuracy.

[0023] During the rotation of the rotating plate 5, when multiple placement slots rotate to the vicinity of the nailing station, the second hydraulic rod 11 is activated in sequence to lower the positioning ring 14 and lock the corresponding upper bearing retainer 13. At this time, the nail feeding machine simultaneously delivers nails to multiple guide nail hoses 6. The nails reach the mounting holes of the bearing retainers through the guide cylinders. Then, the first hydraulic rod 7 is activated to lower the pressing plate and perform nailing and fixing operations on multiple bearing retainers.

[0024] Implementation effect: This automatic bearing retainer mounting device drives the rotating plate 5 to rotate via the servo motor 16 mounted on the support base 1. It can quickly rotate the placement slot containing the lower bearing retainer 12, the bearing, and the upper bearing retainer 13 to the mounting position. The second hydraulic rod 11 pushes the lifting plate 10 down, so that the positioning ring 14 accurately positions the upper bearing retainer 13. The guide hose 6 is connected to the nail feeding machine to deliver the nails, thereby completing the mounting work of the bearing retainer.

[0025] By starting the servo motor 16 to drive the rotating plate 5 to rotate, the already installed bearing retainer can be rotated to the pressing position, i.e., the first support frame 8. At this time, the first hydraulic rod 7 can be activated. The output end of the first hydraulic rod 7 can drive the pressing plate to descend. Under the action of the extrusion block and support block 4 installed at the bottom of the pressing plate, the purpose of installing the bearing retainer and pressing and fixing the installed bearing is completed.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
