Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, and in particular to a bearing auxiliary assembly fixture with a guiding structure. Background Technology
[0002] Bearings are crucial transmission components in the mechanical field, offering advantages such as reducing frictional resistance, improving mechanical efficiency, and ensuring rotational accuracy. They support rotating mechanical bodies and reduce their coefficient of friction during movement. Their applications are widespread, ranging from small household appliances and automotive parts to large industrial machine tools, wind turbines, and aerospace equipment; almost any mechanical device involving rotational motion relies heavily on bearings.
[0003] The core structure of a bearing mainly consists of an inner ring, an outer ring, steel balls, and a cage. The inner ring is usually tightly fitted to the shaft and rotates with the shaft; the outer ring is mostly fixed to the bearing housing or machine casing, providing support; the steel balls, as rolling elements, are evenly distributed between the inner and outer rings, reducing friction by rolling instead of sliding; the cage is used to separate the steel balls, preventing them from colliding with each other, while ensuring the uniform distribution of the steel balls in the circumferential direction.
[0004] However, during the bearing assembly process, the assembly of the inner ring, steel balls, and cage often relies on manual alignment. Steel balls are prone to falling out of the gap between the inner ring and the cage, which can easily lead to uneven distribution of steel balls. To address this issue, a bearing auxiliary assembly fixture with a guiding structure is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a bearing auxiliary assembly fixture with a guiding structure, which aims to improve the problem of the cumbersome installation of steel balls in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bearing auxiliary assembly fixture with a guiding structure includes a fixture body and a positioning rod. The fixture body has an upper groove and a lower groove inside. An assembly guide component is installed inside the upper groove. An installation ring is fixedly connected to the bottom of the fixture body. A disassembly and assembly component is installed inside the installation ring. The assembly guide assembly includes multiple limiting pins, which are slidably connected inside the tooling body. A spring is sleeved on the outer side of the limiting pin, and a guide groove is provided on the top of the tooling body. As a further description of the above technical solution: The disassembly and assembly assembly includes two housings, which are fixedly connected inside the mounting ring. Two locking tongues are installed inside the housings, and a spring is fixedly connected inside the locking tongues. A base is installed at the bottom of the tooling body, and two locking slots are opened inside the base. The locking tongues are engaged inside the locking slots. As a further description of the above technical solution: The tooling body has multiple sliding grooves inside, and the limiting pin is slidably connected inside the sliding grooves; As a further description of the above technical solution: A blocking ring is fixedly connected to the middle of the limiting pin, and a spring is fixedly connected to the outside of the blocking ring. As a further description of the above technical solution: A fixing ring is fixedly connected inside the slide groove, and the limiting pin is slidably connected inside the fixing ring; As a further description of the above technical solution: The positioning rod is fixedly connected to the middle of the base; As a further description of the above technical solution: A partition is fixedly connected inside the outer shell, and two springs are fixedly connected to both sides of the partition. As a further description of the above technical solution: An adjusting plate is fixedly connected to the top of the locking tongue, and the adjusting plate is located at the top of the mounting ring.
[0007] This utility model has the following beneficial effects: 1. In this utility model, through the guide groove structure, the steel balls can be automatically guided to the pocket position of the retainer under the constraint of the guide groove, and achieve uniform distribution under the dual action of gravity and the guide structure. After the inner ring assembly and the outer ring are pre-assembled separately, the inner ring assembly can continue to move downward with the retraction of the limit pin and spring, until it is precisely matched with the outer ring that is pre-placed in the lower groove, thus completing the overall assembly of the bearing.
[0008] 2. In this utility model, by using an adjusting plate, spring, locking tongue, etc., the locking constraint between the base and the mounting ring is released, and the two can be separated. The outer ring can be placed stably in the lower groove structure in advance, leaving sufficient operating space for the subsequent overall assembly process. This not only greatly simplifies the process of multi-component collaborative installation, but also lays the foundation for the assembly accuracy of the overall bearing by positioning the outer ring reference position in advance.

[0011] 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.
[0012] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a bearing auxiliary assembly fixture with a guiding structure, comprising a fixture body 1 and a positioning rod 3. The fixture body 1 has an upper groove 6 and a lower groove 7 inside. The upper groove 6 is used to accommodate components such as the bearing inner ring, retainer, and steel balls and to perform related assembly operations. The lower groove 7 is specifically used to place the bearing outer ring, providing space for the pre-installation of the outer ring. An assembly guide component is installed inside the upper groove 6. This component can guide the steel balls to be accurately distributed and assist the assembly of the inner ring, retainer, and steel balls with the outer ring smoothly. An installation ring 5 is fixedly connected to the bottom of the fixture body 1. A disassembly and assembly component is installed inside the installation ring 5. Through this component, the fixture body 1 and the base 4 can be easily separated and connected, facilitating the pre-placement of the outer ring. The assembly guide assembly includes multiple limiting pins 9, which limit the components placed in the upper groove 6. The limiting pins 9 are slidably connected inside the fixture body 1. A spring 10 is sleeved on the outer side of each limiting pin 9, providing elastic support. The limiting pin 9 retracts when stressed and returns to its original position when unstressed. A guide groove 2 is provided at the top of the fixture body 1, guiding the placement of steel balls so they can slide upwards towards the holder and achieve uniform distribution. Multiple sliding grooves 8 are provided inside the fixture body 1, and the limiting pins 9 are slidably connected inside these grooves. The sliding grooves 8 provide a path and space for the sliding of the limiting pins 9. The middle of each limiting pin 9 is fixed. A blocking ring 11 is fixedly connected to the spring 10. The blocking ring 11 can limit the spring 10. When the limiting pin 9 moves downward under force, the blocking ring 11 will compress the spring 10, allowing the spring 10 to store elastic potential energy. When the external force disappears, the elastic force of the spring 10 will drive the limiting pin 9 to return to its initial position through the blocking ring 11. The spring 10 is fixedly connected to the outside of the blocking ring 11. A fixing ring 12 is fixedly connected inside the slide groove 8. The limiting pin 9 is slidably connected inside the fixing ring 12. The fixing ring 12 further guides and restricts the sliding of the limiting pin 9. The positioning rod 3 is fixedly connected to the middle of the base 4. The positioning rod 3 can play a positioning role when the tooling body 1 and the base 4 are installed.
[0013] Reference Figures 1-3 The assembly includes two housings 13, which are fixedly connected inside the mounting ring 5. Two locking tongues 14 are installed inside the housings 13, and springs 17 are fixedly connected inside each locking tongue 14, providing outward elasticity. A base 4 is installed at the bottom of the fixture body 1, and two locking grooves 18 are formed inside the base 4. The locking tongues 14 engage with the locking grooves 18, thus fixing the mounting ring 5 and the base 4 together. When the adjusting plate 15 is pinched, springs 17 retract, the locking tongues 14 move towards the center and disengage from the locking grooves 18, separating the base 4 from the mounting ring 5. A partition 16 is fixedly connected inside the housings 13, and two springs 17 are fixedly connected to both sides of the partition 16. The partition 16 separates the internal space of the housings 13, providing independent installation positions for the two springs 17. An adjusting plate 15 is fixedly connected to the top of the locking tongues 14, providing a convenient operating position for the operator. The adjusting plate 15 is located at the top of the mounting ring 5.
[0014] Working principle: First, when installing the outer ring, pinch the adjusting plate 15 to retract the spring 17, causing the locking tongue 14 to move towards the center, thereby separating the base 4 from the mounting ring 5. This allows the outer ring to be placed inside the lower groove 7 in advance, facilitating subsequent bearing assembly. This not only simplifies the operation process but also ensures installation accuracy.
[0015] Next, place the inner ring of the bearing inside the fixture body 1, then place half of the retainer outside the inner ring, and then let the steel balls slide along the guide groove 2 to the top of the retainer and distribute them evenly. In this way, the steel balls can be guided quickly, effectively saving time and improving work efficiency. After that, cover the other half of the retainer to complete the installation of the retainer, steel balls and inner ring.
[0016] After installation, use a tool to press down the installed inner ring, steel ball, and retainer. At this time, the limit pin 9 is under force, causing the spring 10 to contract. The limit pin 9 moves into the slide groove 8, which can quickly complete the installation with the bottom outer ring, further improving work efficiency and ensuring installation accuracy.
[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
