Description

Technical Field

[0001] This utility model relates to an installation and positioning structure, and more particularly to a bearing cage installation and positioning structure. Background Technology

[0002] The bearing cage is one of the core components of a bearing. Its main functions include isolating the rolling elements, guiding their movement, and distributing the load evenly. During automated installation, the cage needs a positioning mechanism to limit its position and prevent it from shifting under force during the pressing process.

[0003] For example, a bearing cage installation device disclosed in Chinese Patent Publication No. CN221474157U includes a feeding mechanism, a ball separator, a lever, a guide plate, a limiting mechanism, a clamping mechanism, a lower pressure block, and an upper pressure block. The ball separator is movably placed on the upper part of the bearing. A positioning rod at the lower part of the ball separator extends into the spaces between the balls for positioning. A guide block is radially provided on the upper part of the ball separator. Two guide plates are provided to form a guide channel and guide blocks. The lower pressure block and the upper pressure block are correspondingly located below and above the middle of the feeding mechanism. A lower positioning groove is machined on the upper part of the lower pressure block for placing the lower cage, and an upper positioning groove is machined on the lower part of the upper pressure block for placing the upper cage. A pressure rod is slidably installed in the upper pressure block, corresponding to the limiting groove on the upper cage. This device guides the ball separator placed on the bearing by installing a lever and a guide plate on the left side of the feeding mechanism, causing the ball separator to rotate to a horizontal position, ensuring the position of the balls is fixed, facilitating the subsequent installation of the upper and lower cages, and providing convenient and accurate positioning.

[0004] Some problems were found when using the existing bearing cage installation device. The cage is placed directly on the pressure block. First, there is no positioning mechanism, so the cage cannot be placed quickly and accurately in the preset position. It needs to be manually and slowly calibrated and placed. Second, during the upward pressing process of the cage, it may be deviated due to force or vibration, which will lead to the problem that the cage cannot be smoothly installed into the bearing. Utility Model Content

[0005] The purpose of this invention is to provide a bearing cage mounting and positioning structure to solve the existing problems mentioned in the background art.

[0007] Preferably, a return spring is fixedly connected inside the limiting sliding hole, and the other end of the return spring is fixedly connected to the bottom of the limiting slider.

[0008] Preferably, a connecting seat is fixedly connected to the lower part of the positioning seat, and a threaded hole is provided on the lower part of the connecting seat.

[0009] Preferably, the placement ring has a placement groove, which cooperates with the bearing cage.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By using a return spring to extend the positioning pin to the upper end of the positioning seat, the bearing cage can be directly fitted onto the positioning pin, thereby achieving quick positioning and installation of the bearing cage and saving the placement and installation time of the bearing cage.

[0012] 2. By using the locating pins to press against the inner wall of the bearing cage, the locating pins can limit the offset and wobbling of the locating pins when the bearing cage is pressed into the bearing, thus preventing the bearing cage from being misaligned and unable to be pressed into the bearing.

[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] Please see Figure 1-3This utility model provides a technical solution: a bearing cage mounting and positioning structure, including a positioning seat 1, a bearing cage 4, and a bearing 5. A limiting sliding hole 101 is provided in the positioning seat 1, and a limiting slider 104 is slidably installed in the limiting sliding hole 101. A positioning post 103 is fixedly connected to the limiting slider 104, and a placement ring 3 is fixedly connected to the positioning seat 1. The bearing cage 4 is placed and installed on the placement ring 3, and the diameter of the positioning post 103 is the same as the inner diameter of the placement groove 301.

[0019] In this embodiment, the positioning post 103 is fixedly installed on the limiting slider 104. The positioning seat 1 has a through hole communicating with the limiting sliding hole 101, allowing the positioning post 103 to pass through the positioning seat 1 and extend to its upper end. The outer diameter of the positioning post 103 is the same as the inner diameter of the placement ring 3. When the positioning post 103 extends to the upper end of the positioning seat 1, it abuts against the inner wall of the placement ring 3. The bearing retainer 4 is placed on the placement ring 3. At this time, the extended portion of the positioning post 103 will be stuck against the inner wall of the bearing retainer 4. When placing the bearing retainer 4, it causes… The bearing cage 4 is directly fitted onto the positioning post 103, and the bottom of the bearing cage 4 is supported by the placement ring 3. The positioning post 103 enables the quick installation and positioning of the bearing cage 4. At the same time, when the bearing cage 4 is pressed into the 9, the inner ring of the 9 will contact the top of the positioning post 103, which can press the positioning post 103 against and squeeze it into the limiting slide hole 101, avoiding interference between the positioning post 103 and the 9. At the same time, the positioning post 103 can limit the left and right displacement and sliding of the bearing cage 4 during the pressing process.

[0020] In order to achieve the purpose of extending the positioning column 103, the device adopts the following technical solution: a return spring 102 is fixedly connected in the limiting slide hole 101, the other end of the return spring 102 is fixedly connected to the bottom of the limiting slider 104, a connecting seat 2 is fixedly connected to the bottom of the positioning seat 1, a threaded hole 201 is opened on the bottom of the connecting seat 2, and a placement groove 301 is opened on the placement ring 3, which cooperates with the bearing retainer 4.

[0021] The return spring 102 can provide a certain thrust to the limit slider 104, and then the limit slider 104 drives the positioning pin 103 to extend to the upper end of the positioning seat 1. The threaded hole 201 can cooperate with the stud to install the device on the cage mounting equipment. The placement groove 301 cooperates with the bearing cage 4 so that the placement ring 3 can fit against the bottom of the bearing cage 4, thereby supporting the bearing cage 4 and extending into the groove of the bearing 5, and locking the bearing cage 4 onto the bearing balls.

[0022] The working principle and usage process of this utility model are as follows: The positioning column 103 can extend to the upper end of the positioning seat 1 under the push of the return spring 102. At this time, the bearing cage 4 is directly sleeved and installed on the positioning column 103, and the bottom of the bearing cage 4 is supported by the placement ring 3. During the downward movement, the inner ring will contact the top of the positioning column 103, which can press the positioning column 103 against the inside of the limiting slide hole 101. The placement ring 3 supports the bearing cage 4 and extends into the groove of the bearing 5, and the bearing cage 4 is locked on the bearing ball, thus realizing the installation of the bearing cage.
