Description

Technical Field

[0001] This utility model relates to the field of bearing cage processing technology, specifically a bearing cage clamping device. Background Technology

[0002] A bearing cage, also known as a bearing retainer or bearing cage assembly, is a metal or non-metal part used to fix and retain the rolling elements of a bearing. It partially encloses all or part of the rolling elements and moves with them, isolating them and typically guiding and holding them within the bearing. The cage evenly isolates and fixes the rolling elements inside the bearing, preventing collisions and friction between them, thus reducing energy loss and wear, extending bearing life, guiding the rolling elements along the correct trajectory within the bearing, ensuring smooth operation, and preventing the rolling elements from deviating from their normal track, which could cause the bearing to seize or be damaged. The cage can hold lubricant; by supplying lubricant, it reduces friction between the rolling elements and the cage, lowering bearing wear and energy loss. Simultaneously, the cage also provides a certain degree of sealing, preventing external impurities from entering the bearing and protecting its normal operation.

[0003] Currently, during the process of installing rollers onto the cage, the pressure plate is directly pressed against the outer or inner ring of the cage by bolting. The stress point is concentrated at a single point, which can easily lead to excessive local pressure on the cage and cause deformation.

[0004] Therefore, a bearing cage clamping device is proposed to solve the above problems. Utility Model Content

[0005] 1. Technical problem to be solved by the utility model

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a bearing cage clamping device, which aims to solve the problem that in the prior art, the pressure plate is directly pressed against the outer or inner ring of the cage by bolt screwing, and the force point is concentrated at a single point, which easily leads to excessive local pressure on the cage and deformation.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A bearing cage clamping device includes an operating table. A clamping mechanism and a hydraulic telescopic column are installed on the top of the operating table. A positioning cylinder for feeding the bearing cage is installed on the clamping mechanism. Multiple pressure blocks are installed on the outside of the positioning cylinder to clamp the bearing cage simultaneously in multiple directions. The hydraulic telescopic column can squeeze the multiple pressure blocks outwards at the same time.

[0010] As a preferred embodiment of this utility model, the top of the operating table is provided with a circular slot, and a connecting plate is installed on the top edge of the circular slot. A motor is installed inside the operating table, and the rotating shaft of the motor is located at the center of the inner side of the circular slot and is fixedly connected to the center of the bottom of the connecting plate.

[0011] As a preferred embodiment of this utility model, a support frame is installed at one top end of the operating table, the top of the hydraulic telescopic column is fixedly installed at one top inner side of the support frame, the bottom of the hydraulic telescopic column is semi-circular, the hydraulic telescopic column is located directly above the top of the positioning cylinder, and the top of the hydraulic telescopic column is rotatably connected to the support frame.

[0012] As a preferred embodiment of this utility model, four sliding rods are installed at equal intervals on the top and bottom of the outer ring surface of the positioning cylinder. The pressure block is fixedly connected to one end of the sliding rod, and the other end of the sliding rod is slidably inserted into the inner side of the positioning cylinder. Four positioning sleeves are installed at equal intervals on the top and bottom of the inner side of the positioning cylinder.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention involves fitting a bearing cage onto a positioning cylinder and using a hydraulic telescopic column to extend downwards into the inner side of the positioning cylinder. This causes multiple pressure blocks on the outside of the positioning cylinder to simultaneously press outwards. At this time, the pressure blocks in multiple directions simultaneously compress the inner wall of the bearing cage, thereby achieving the clamping operation of the bearing cage. Furthermore, because the inside of the bearing cage is subjected to force in multiple directions simultaneously, the force is more evenly distributed, avoiding excessive local pressure and deformation caused by single-point force. At the same time, the clamping operation is more efficient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 This embodiment provides a bearing cage clamping device, including an operating table 1. A clamping mechanism 2 and a hydraulic telescopic column 31 are installed on the top of the operating table 1. A positioning cylinder 21 for feeding the bearing cage is installed on the clamping mechanism 2. Multiple pressure blocks 23 are installed on the outside of the positioning cylinder 21 to simultaneously clamp the bearing cage in multiple directions. The hydraulic telescopic column 31 can simultaneously squeeze the multiple pressure blocks outward. When the bearing cage clamping device is in use, the bearing cage is sleeved on the positioning cylinder 21, and the hydraulic telescopic column 31 extends downward and enters the inside of the positioning cylinder 21, squeezing the pressure blocks 23 on the outside of the positioning cylinder 21 outward in multiple directions at the same time. At this time, the pressure blocks 23 in multiple directions simultaneously squeeze the inner wall of the bearing cage, thereby realizing the clamping operation of the bearing cage. Since the inside of the bearing cage is subjected to force in multiple directions at the same time, the force is more even, avoiding excessive local pressure and deformation caused by single-point force, and the clamping operation is more efficient.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, a circular slot 11 is provided on the top of the operating table 1. A connecting plate 13 is installed on the top edge of the circular slot 11. A motor 12 is installed inside the operating table 1. The rotating shaft of the motor 12 is located at the center of the inner side of the circular slot 11 and is fixedly connected to the bottom center of the connecting plate 13. Therefore, when the motor 12 rotates, it can drive the connecting plate 13 to rotate.

[0026] In this embodiment, as Figure 1 and Figure 3 As shown, four sliding rods 22 are installed at equal intervals on the top and bottom of the outer ring surface of the positioning cylinder 21. The pressure block 23 is fixedly connected to one end of the sliding rod 22. The other end of the sliding rod 22 is slidably inserted into the inner side of the positioning cylinder 21. Four positioning sleeves 24 are installed at equal intervals on the top and bottom of the inner side of the positioning cylinder 21. The sliding rod 22 is slidably connected to the inner side of the positioning sleeve 24. One end of the sliding rod 22 passes through the positioning sleeve 24 and is fixedly installed with a limiting plate. A spring 25 is sleeved on the outer ring surface of the sliding rod 22. The spring 25 is connected between the limiting plate and the positioning sleeve 24. Therefore, when the limiting plate is squeezed, the sliding rod 22 slides outward and squeezes the pressure block 23 to move. After the squeezing force disappears, the sliding rod 22 returns to its original position.

[0027] In this embodiment, as Figure 1 and Figure 3 As shown, when the hydraulic telescopic column 31 extends downward and inserts into the inner side of the positioning cylinder 21, it will simultaneously squeeze the four limiting plates, causing the four pressure blocks 23 to move outward at the same time. In the initial state, the pressure blocks 23 are close to the outer side of the positioning cylinder 21 and the bearing cage is sleeved on the positioning cylinder 21. The pressure blocks 23 are located inside the bearing cage, and the die hole of the bearing cage is located between the pressure blocks 23 at the top and bottom of the outer ring surface of the positioning cylinder 21. Therefore, the pressure blocks 23 can move outward at the same time to press the inner wall of the bearing cage, without obstructing the die hole position of the bearing cage, and without interfering with the installation of the rollers.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the positioning cylinder 21 is located on the top of the connecting plate 13. Two buttons are installed at the corner of the top end of the positioning cylinder 21. One button controls the start and stop of the motor 12, and the other controls the extension and retraction of the hydraulic telescopic column 31. Therefore, after the bearing cage is pressed, the position of the bearing cage can be adjusted by rotating the connecting plate 13, which facilitates the installation of the roller.

[0029] Working principle: When using this bearing cage clamping device, the bearing cage is first placed on the positioning cylinder 21, and the pressure block 23 is located inside the bearing cage. At this time, the hydraulic telescopic column 31 is activated to extend downward and squeeze the inner limit block of the positioning cylinder. This causes the slide rod 22 to drive the pressure blocks in multiple directions to simultaneously squeeze and clamp the inner wall of the bearing cage, thereby realizing the clamping operation of the bearing cage. Since the inside of the bearing cage is subjected to force in multiple directions at the same time, the force is more even, avoiding excessive local pressure and deformation caused by single-point force. At the same time, the clamping operation is more efficient. After the bearing cage is clamped, the position of the bearing cage can be adjusted by rotating the connecting plate 13 to facilitate the installation of the rollers.

[0030] All technical features in this embodiment can be freely combined according to actual needs. The above embodiment is a preferred implementation of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
