Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a bearing visual inspection device with a grease injection mechanism. Background Technology

[0002] With the rapid development of modern industrial technology, bearings, as core components in various rotating machinery, directly determine the performance, precision, and service life of the entire equipment. Therefore, rigorous visual defect inspection and precise lubrication are two crucial aspects of ensuring product quality during bearing manufacturing. Automated visual inspection and lubrication equipment can effectively replace manual labor, enabling accurate identification of bearing defects such as dents and corrosion, and standardized lubrication treatment. This provides an important technological guarantee for improving production efficiency and product consistency.

[0003] Existing bearing inspection and grease injection technologies have shortcomings: On the one hand, in automated processes, the methods for fixing bearing workpieces are relatively simple or rely on manual placement. During visual inspection and grease injection operations, errors caused by unstable positioning or vibration affect the quality of inspection results and the accuracy of grease injection location. On the other hand, after grease injection, the uniform distribution of lubricating grease is crucial for bearing performance. The lack of effective automated grease-leveling methods after grease injection means that uneven grease distribution can affect bearing lifespan and lead to inconsistent product performance. Therefore, a bearing visual inspection device with a grease injection mechanism is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bearing visual inspection device with a grease injection mechanism, which aims to improve the problems of instability and uneven grease distribution during bearing inspection and grease injection in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bearing visual inspection device with a grease injection mechanism includes a worktable and a grease reservoir. A U-shaped frame is fixedly connected to the top of the worktable, and two detection probes are fixedly connected to the inner top wall of the U-shaped frame. A robotic arm is installed on the outside of the worktable. An air pump is fixedly connected to the top of the grease reservoir. A connecting pipe is fixedly connected to the input end of the air pump, and a flexible tube is fixedly connected to the output end of the air pump. A grease injection head is fixedly connected to the end of the flexible tube away from the air pump. Two guide rails are fixedly connected inside the worktable, and two sliders are slidably connected between the two guide rails. A fixing block is fixedly connected to each of the two sliders on opposite sides. A fixing column is fixedly connected to the top of the slider, and a fixing plate is fixedly connected to the outside of the fixing column. A motor is fixedly connected to the inner bottom wall of the worktable, and a rotating plate is fixedly connected to the output end of the motor. A bearing body is set on the top of the worktable, and a vibration assembly is set inside the worktable. As a further description of the above technical solution: The vibration assembly includes a pad and a fixing block 1. The pad is fixedly connected to the inner bottom wall of the workbench, and the fixing block 1 is fixedly connected to the inner wall of the workbench. A motor 2 is fixedly connected to the top of the pad, and a turntable is fixedly connected to the output end of the motor 2. A connecting plate is rotatably connected to the outer side of the turntable, and a connecting block is rotatably connected to the side of the connecting plate away from the turntable. A sliding rod is slidably connected inside the fixing block 1, and a rubber block is fixedly connected to the top of the sliding rod. As a further description of the above technical solution: One end of the rotating plate is rotatably connected to the top of one of the fixed blocks 2, and the other end of the rotating plate is rotatably connected to the top of another fixed block 2; As a further description of the above technical solution: The top of the fat storage tank is fixedly connected to a feed pipe, and the end of the feed pipe away from the air pump is fixedly connected to the inside of the fat storage tank.

[0006] This utility model has the following beneficial effects: 1. In this utility model, when it is necessary to inspect and inject grease into the bearing body, the bearing body is fixed. The motor drives the rotating plate, which drives two sliders to move towards each other on the guide rail. The sliders drive the fixed plate to move through the fixed column, thereby firmly clamping the bearing body, thus achieving the automatic clamping and loosening effect of the bearing body, and ensuring the stability of the bearing position during the inspection and grease injection process.

[0007] 2. In this utility model, after the bearing body is greased, the second motor in the vibration assembly is started. The second motor drives the turntable, connecting plate, connecting block and slide rod to move, so that the rubber block at the top of the slide rod repeatedly hits the inner top wall of the worktable, thereby generating high-frequency vibration of the entire worktable. This vibration is transmitted to the bearing body, which helps the grease to be evenly distributed inside the bearing, thus achieving uniform grease distribution. Attached Figure Description

[0011] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a bearing visual inspection device with a grease injection mechanism, comprising a worktable 1 and a grease tank 2. A U-shaped frame 4 is fixedly connected to the top of the worktable 1, and two detection probes 10 are fixedly connected to the inner top wall of the U-shaped frame 4. A robotic arm 5 is installed on the outer side of the worktable 1. An air pump 6 is fixedly connected to the top of the grease tank 2. A connecting pipe 7 is fixedly connected to the input end of the air pump 6, and a hose 8 is fixedly connected to the output end of the air pump 6. A grease injection head 9 is fixedly connected to the end of the hose 8 away from the air pump 6.

A bearing body 3 is provided on the top of the worktable 1, and a vibration component is provided inside the worktable 1. One end of the rotating plate 23 is rotatably connected to the top of a fixed block 25, and the other end of the rotating plate 23 is rotatably connected to the top of another fixed block 25. A feed pipe is fixedly connected to the top of the grease storage tank 2, and the end of the connecting pipe 7 away from the air pump 6 is fixedly connected inside the grease storage tank 2. The bearing body 3 is located between two fixed plates 11, with opposite sides of the two fixed plates 11 abutting against the surface of the bearing body 3. Both fixed columns 12 penetrate the top of the workbench 1 and are slidably connected inside the workbench 1. The end of the flexible hose 8 away from the air pump 6 penetrates the inner top wall of the U-shaped frame 4 and is located directly above the bearing body 3.

[0012] Workbench 1 serves as the basic load-bearing structure of the equipment, used to install and support various components. Grease reservoir 2 stores the grease required for bearing grease injection. U-shaped frame 4 provides a fixed mounting position for inspection probe 10, allowing it to be aligned with the bearing below for inspection. Inspection probe 10 is used for visual inspection of the bearing body 3, identifying defects such as dents, black scale, waste material, scratches, and rust. Robotic arm 5 is used to grab and move the finished bearing to the next process after grease injection. Air pump 6 provides power to deliver the grease from grease reservoir 2 to grease injection head 9 through connecting pipe 7 and hose 8. Connecting pipe 7 connects grease reservoir 2 and air pump 6, enabling air pump 6 to draw grease from grease reservoir 2. Hose 8 connects air pump 6 and grease injection head 9, delivering grease from air pump 6 to grease injection head 9. Grease injection head 9 is used to precisely inject grease into the bearing that has passed visual inspection. The purpose of grease injection is to ensure the reliability, lifespan, and operational accuracy of the bearing, which is the basic guarantee for the normal operation of mechanical equipment. Guide rail 14 provides guidance and support for the sliding of slider 13, ensuring that slider 13 moves along a fixed trajectory. Sliding slider 13 on guide rail 14 drives fixed block 25, fixed column 12, and fixed plate 11 to move synchronously. Fixed block 25 is rotatably connected to rotating plate 23, causing slider 13 to slide under the drive of rotating plate 23. Fixed column 12 connects slider 13 and fixed plate 11, transmitting the movement of slider 13 to fixed plate 11. Fixed plate 11 moves under the drive of fixed column 12, used to clamp or release bearing body 3, achieving fixation or release of bearing body 3. Motor 15 provides power for the rotation of rotating plate 23. Rotating plate 23 rotates under the drive of motor 15, driving the two sliders 13 to slide in opposite or opposite directions through rotational connection with fixed block 25. Vibration assembly is installed inside worktable 1 to assist in the uniform distribution of lubricating grease during the grease injection process, achieving grease evenness. The grease drain tube is fixed to the top of the grease reservoir 2 and is used to add lubricating grease into the grease reservoir 2.

[0013] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The vibration assembly includes a pad 17 and a fixing block 21. The pad 17 is fixedly connected to the inner bottom wall of the workbench 1, and the fixing block 21 is fixedly connected to the inner wall of the workbench 1. A motor 16 is fixedly connected to the top of the pad 17, and a turntable 18 is fixedly connected to the output end of the motor 16. A connecting plate 19 is rotatably connected to the outside of the turntable 18, and a connecting block 20 is rotatably connected to the side of the connecting plate 19 away from the turntable 18. A sliding rod 22 is slidably connected inside the fixing block 21, and a rubber block 24 is fixedly connected to the top of the sliding rod 22. The end of the hose 8 away from the air pump 6 passes through the inner top wall of the U-shaped frame 4 and is located directly above the bearing body 3.

[0014] The vibration assembly assists in the even distribution of grease during the grease injection process, achieving a uniform grease distribution function. The grease discharge tube is fixed to the top of the grease reservoir 2 for adding grease into the reservoir 2. The pad 17 is fixed to the bottom wall of the workbench 1 to support and fix the motor 16. The fixing block 21 is fixed to the inner wall of the workbench 1 to provide guidance and support for the sliding of the slide rod 22. The motor 16 is fixed to the top of the pad 17 to provide power for the movement of the vibration assembly. The turntable 18 rotates under the drive of the motor 16, driving the connecting plate 19 to move through its rotational connection with the connecting plate 19. One end of the connecting plate 19 is rotatably connected to the turntable 18, and the other end is rotatably connected to the connecting block 20 to convert the rotational motion of the turntable 18 into the reciprocating motion of the connecting block 20. The connecting block 20 is connected to the connecting plate 19 and the slide rod 22, transmitting the motion of the connecting plate 19 to the slide rod 22. The slide rod 22 slides within the fixing block 21, reciprocating under the drive of the connecting block 20 and driving the rubber block 24 to move. The rubber block 24 is fixed to the top of the slide bar 22. Under the action of the slide bar 22, it repeatedly impacts the inner top wall of the worktable 1, causing the worktable 1 to vibrate, thereby helping the lubricating grease in the bearing to be evenly distributed.

[0015] Working principle: First, the bearing body 3 to be processed is placed on top of the workbench 1. Then, motor 15 is started, and its output end drives the rotating plate 23 to rotate. The rotating plate 23 drives two sliders 13 to move towards each other on the guide rail 14 through the connection with the fixed block 25. The sliders 13 drive the fixed plate 11 to move through the fixed column 12, thereby firmly clamping the bearing body 3. After clamping, the detection probe 10 located on the U-shaped frame 4 performs visual inspection on the bearing body 3 to determine whether there are any preset defects. For the bearing body 3 that passes the inspection, the air pump 6 is started. The air pump 6 pressurizes the inside of the grease tank 2 and delivers the grease through the connecting pipe 7 and the hose 8 to the grease injection head 9, and the grease injection head 9 injects the set amount of grease into the bearing. After grease injection is completed, motor 16 in the vibration assembly is activated. Motor 16 drives the turntable 18, connecting plate 19, connecting block 20, and slide rod 22 to move, causing the rubber block 24 at the top of slide rod 22 to repeatedly impact the inner top wall of worktable 1, thereby generating high-frequency vibration in the entire worktable 1. This vibration is transmitted to the bearing body 3, assisting in the even distribution of grease inside the bearing, achieving uniform grease distribution. After the grease distribution process is completed, motor 15 rotates in the reverse direction, causing the fixing plate 11 to loosen the bearing body 3. Finally, the robotic arm 5 on the outside of worktable 1 picks up the finished bearing after grease injection and removes it, completing the entire automated inspection and grease injection process.

[0016] 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.
