Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to an auxiliary ball loading device for bearing processing. Background Art

[0002] A ball loading device for bearing machining is typically used during bearing assembly to accurately install steel balls between the inner and outer rings of the bearing. Existing devices include a ball feeding system, a positioning tray, and a drive mechanism. The ball feeding system delivers the steel balls to the loading position via vibration or airflow, while the positioning tray ensures that each steel ball is placed in the correct sequence and position. The drive mechanism, usually electric or pneumatic, uses precise control to ensure that the steel balls on the tray are accurately fed one by one into the inner and outer rings of the bearing. This device improves assembly efficiency and accuracy, avoids errors and inconsistencies that occur during manual assembly, and is particularly suitable for automated assembly in mass production. By reducing manual intervention, the ball loading device not only improves production efficiency but also ensures the consistency and quality of bearing assembly, and is suitable for machining various small to medium-sized bearings.

[0003] Existing ball loading devices for bearing processing have poor adaptability. They are usually designed to be fixed and only suitable for bearings of specific specifications. It is difficult to quickly adjust them to accommodate bearings of different sizes or types. This invention solves this problem by installing a removable fixing rod on the top of the eccentric roller. By replacing the fixing rod with different models, it can accommodate different models of bearing inner rings. At the same time, the clamping structure can fix different models of bearing outer rings, which facilitates subsequent ball loading. In addition, the existing ball loading device has a complex structure and is prone to dust and oil accumulation, especially in the feeding system and ball groove, which are difficult to clean. This invention solves this problem by installing a cleaning mechanism on one side of the worktable. Through the cooperation of a water pump and a water tank, cleaning fluid is sprayed onto the worktable to clean it promptly after use.

[0004] Therefore, we propose an auxiliary ball loading device for bearing machining. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Current ball-loading devices for bearing processing have poor adaptability, are typically fixed designs, and can only be used for bearings of specific specifications, making it difficult to quickly adjust to accommodate bearings of different sizes or types. To solve this problem, this invention incorporates an easily detachable fixing rod on the top of the eccentric roller, allowing for the replacement of different types of fixing rods to accommodate different bearing inner rings. Simultaneously, a clamping structure securely fixes different types of bearing outer rings, facilitating the subsequent ball-loading process. Furthermore, existing ball-loading devices have complex structures and are prone to dust and oil accumulation, particularly in the feeding system and ball groove, making cleaning difficult. This invention addresses this by installing a cleaning mechanism on one side of the workbench, combined with a water pump and tank, to spray cleaning fluid onto the workbench, promptly cleaning it after use and ensuring the cleanliness and normal operation of the equipment.

[0028] Example 1

[0029] like Figure 1-6As shown, this utility model provides a technical solution: an auxiliary ball loading device for bearing processing, including a worktable 1, a fixed frame 2 fixedly installed on the top of the worktable 1, a cylinder 3 threadedly connected to the inside of the fixed frame 2 via a screw, a movable crossbar 4 fixedly installed on the side of the cylinder 3 away from the fixed frame 2, the movable crossbar 4 guides a sliding ring sleeve 5 to ensure the stability of the movement path of the sliding ring sleeve 5 and to allow for precise adjustment, both ends of the movable crossbar 4 are slidably connected to the sliding ring sleeve 5, the two ends of the sliding ring sleeve 5 are tightly against the inner wall of the fixed frame 2, and the sliding ring sleeve 5 is in close contact with the inner wall of the fixed frame 2 through both ends. To achieve stable sliding, the top of the sliding ring sleeve 5 is rotatably connected to the first connecting rod 6. The end of the first connecting rod 6 away from the sliding ring sleeve 5 is rotatably connected to the top of the fixed frame 2. The bottom of the sliding ring sleeve 5 is rotatably connected to the second connecting rod 7. The end of the second connecting rod 7 away from the sliding ring sleeve 5 is rotatably connected to the clamping rod 8. The fixed frame 2 has rails at both ends on the side away from the cylinder 3 for the clamping rod 8 to slide. These rails ensure that the clamping rod 8 can slide smoothly within the set rails, controlling the accuracy and stability during the bearing assembly process. The end of the clamping rod 8 away from the fixed frame 2 is fixedly installed with a clamping block 9.

[0030] Fixed grooves 14 are fixedly installed at both ends of the top of the workbench 1 on the side away from the fixed frame 2. Each fixed groove 14 has a sliding groove inside, and a slider 15 is slidably connected inside the sliding groove. A threaded rod 16 is rotatably connected to the corresponding side of the two sliders 15 through a bearing. A threaded block 17 is threadedly connected to the outer circumference of the threaded rod 16. The rotation of the threaded rod 16 and the slider 15 is connected by the bearing to ensure that the rotation of the threaded rod 16 can drive the linear movement of the threaded block 17 and maintain the stability of the movement. A water tank 18 is fixedly installed on the top of the threaded block 17. The rotation of the threaded rod 16 allows the water tank 18 to move synchronously with the threaded block 17. A spray pipe 19 is fixedly connected to one side of the water tank 18.

[0031] Example 2

[0032] Eccentric wheels 10 are provided on the corresponding side of the two clamping blocks 9. The eccentric wheels 10 are rotatably connected to the top of the workbench 1 via bearing seats. The top of the eccentric wheels 10 is provided with a detachable fixing rod, which allows the device to adapt to different working conditions and quickly replace bearings of different models. Especially in the assembly process of various bearings or workpieces, the end of the spray pipe 19 away from the water tank 18 is close to the top of the workbench 1. The water tank 18 contains a water pump. The output end of the water pump is fixedly connected to the spray pipe 19, and the input end of the water pump is fixedly connected to the inside of the water tank 18. Through the cooperation of the water pump and the water tank 18, the device can effectively clean the oil and dust on the workbench 1 and reduce the impact of dust and dirt on the performance of the device.

[0033] Example 3

[0034] A support frame 11 is fixedly installed on one side of the workbench 1. A feeding hopper 12 is fixedly installed at the end of the support frame 11 away from the workbench 1. A distribution wheel 13 is rotatably connected inside the feeding hopper 12 through a bearing. The rotation of the distribution wheel 13 ensures that the number of balls loaded each time is consistent. The distribution wheel 13 is tightly attached to the inner wall of the feeding hopper 12. A robot arm 20 is fixedly installed on the top of the workbench 1. A suction cup is fixedly installed at the end of the robot arm 20 near the clamping block 9. The suction cup can quickly and stably grasp and release according to the operation requirements, which greatly improves the automation level of the production line. A discharge port is opened on the side of the workbench 1 away from the fixed frame 2. Multiple support legs 21 are fixedly installed around the bottom of the workbench 1. The bottom of the support legs 21 is provided with anti-slip texture, which effectively increases the friction between the support legs and the ground and prevents the workbench from sliding or shifting during operation. Especially under high load or fast movement, the anti-slip design can provide additional stability.

[0035] The working process of this utility model:

[0036] Step one: The operator first selects a suitable fixing rod according to the bearing model. Since the fixing rod on the eccentric wheel 10 can be quickly disassembled and replaced to accommodate different bearing inner rings. Then, the outer ring of the bearing is fixed to the worktable 1 by the clamping block 9 and the clamping rod 8. The clamping rod 8 is connected to the fixed frame 2 via a sliding rail inside the fixed frame 2, and is driven by the cylinder 3 to move the moving crossbar 4. At this time, the sliding rings 5 ​​slidably connected to both ends of the moving crossbar 4 move towards each other, and then the clamping rod 8, which is rotatably connected to the sliding rings 5 ​​by the second connecting rod 7, moves towards each other, enabling the device to fix the outer ring of the bearing that needs to be loaded with balls.

[0037] Step 2: After fixing, the balls are loaded into the hopper 12. The material distribution wheel 13 is rotated inside the hopper 12 to ensure that the number of balls loaded each time is consistent. The material distribution wheel 13 is powered by an external drive source and can be stopped as needed. After the balls are loaded, the eccentric wheel 10 is started so that the balls can be evenly distributed between the inner and outer rings of the bearing. When the eccentric wheel 10 rotates and the balls are evenly distributed, the rotational force of the eccentric wheel 10 is greater than the clamping force, which drives the outer ring of the bearing and pushes the clamping block 9 and the clamping rod 8 to adjust their positions so that the clamping block 9 and the clamping rod 8 cooperate with the action of the eccentric wheel 10.

[0038] Step 3: After the bearing balls are loaded or the worktable is used, the water pump, in conjunction with the water tank 18 and the spray pipe 19, sprays cleaning fluid onto the worktable 1. During the cleaning process, the water pump in the water tank 18 delivers water to the worktable through the spray pipe 19, promptly cleaning up any residue after use and ensuring that the long-term operation of the device is not affected by dirt. The surface of the worktable is effectively cleaned by the cleaning mechanism, preventing the accumulation of oil and dust and keeping the device clean. After the ball loading is completed, the robot arm 20 removes the outer ring of the bearing from the worktable and removes the processed bearing from the unloading port, preparing for the next round of operations.

[0039] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
