Description

Technical Field

[0001] This utility model belongs to the field of bearing wear detection technology, and in particular relates to a bearing wear detection device. Background Technology

[0002] As a component of bearings, bearing shells play a crucial role in the automotive industry and everyday life. In the automotive industry, bearing shells are responsible for supporting and protecting the rotating shaft of the engine, and withstand the immense pressure under harsh environments such as high temperature, high pressure, and high speed. Therefore, the quality and performance requirements for automotive engine bearing shells are extremely high, affecting the overall operational stability and performance of the vehicle. Regarding the technology for repairing worn journals, domestic methods generally include welding repair and pitting. If the downtime is short and spare parts are available, replacing the entire shaft is usually the preferred method. However, wear detection of the bearing shells is crucial during repair. It is necessary to inspect the wear points and degree of wear to facilitate repair. Wear detection is also practiced in industries such as aerospace and petrochemicals.

[0003] The current testing method does not include auxiliary positioning equipment, making the entire unit prone to shaking, which affects normal testing and requires frequent manual adjustments, increasing the labor intensity. At the same time, dust particles and residues from the bearing itself and during testing can easily cause equipment blockage if not handled in time, reducing the overall service life. Therefore, it is necessary to design a bearing wear detection device to solve the above problems. Summary of the Invention

[0004] This invention provides a bearing wear detection device, which aims to solve the problems existing in the prior art.

[0005] This utility model is implemented as follows: a bearing wear detection device includes a platform, a frame vertically installed on the top of the platform, a rectangular tube provided on the top of the platform, a lifting component provided on the top of the rectangular tube, a compensation component provided inside the rectangular tube, and a C-shaped body installed on the top of the platform, with a fixing component provided on the C-shaped body.

[0006] The compensation component includes springs and a lifting body. Multiple springs are vertically installed at the top of the rectangular tube, and a lifting body is slidably inserted into the bottom of the rectangular tube. The bottom of each spring is connected to the top of the lifting body. A friction roller is rotatably installed at the bottom of the lifting body, and a motor is installed on the outer side of the bottom of the lifting body. The motor is used to drive the friction roller to rotate.

[0007] By adopting the above technical solution, the friction roller is always in contact with the processing to wear it down.

[0008] As a further embodiment of this utility model: the lifting assembly includes a first electric push rod, which is vertically installed at the top of the frame, and a rectangular tube is installed at the output end of the first electric push rod.

[0009] By adopting the above technical solution, the height of the friction roller can be adjusted over a wide range.

[0010] As a further embodiment of this utility model: connecting plates are horizontally installed on both sides of the outer side of the rectangular tube, and guide rods are slidably passed through the connecting plates, with the tops of the guide rods fixedly installed to the top of the frame.

[0011] By adopting the above technical solution, the stability of the rectangular tube's vertical movement is improved.

[0012] As a further embodiment of this utility model: the fixing component includes a mounting bracket, a second electric push rod, and a fixing plate. Mounting brackets are installed at both ends of the C-shaped body, and a second electric push rod is installed inside each mounting bracket. A fixing plate is installed at the output end of each second electric push rod, and the fixing plate slides through the C-shaped body.

[0013] By adopting the above technical solution, it is possible to fix the arc-shaped workpiece.

[0014] As a further embodiment of this utility model: guide posts are symmetrically installed on the outer side of the fixing plate, and the guide posts slide through the mounting frame.

[0015] By adopting the above technical solution, the stability of the fixing plate in fixing the arc-shaped workpiece is improved.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the bearing wear detection device is equipped with springs and a lifting body. When the workpiece is being tested, the workpiece will become thinner during long-term friction. At this time, multiple springs installed inside the rectangular tube can push the lifting body to move down, ensuring that the friction roller can always contact the arc and rub it.

[0017] In addition, the bearing wear detection device is also equipped with a mounting bracket, a second electric push rod, and a fixing plate. After the arc-shaped workpiece is placed into the receiving groove at the top of the C-shaped body, the second electric push rod is activated to drive the fixing plates to move closer to each other. The fixing plates are used to move the workpiece to the top two ends of the arc-shaped workpiece. The fixing plates are used to clamp half of the workpiece thickness, thereby fixing the workpiece on the C-shaped body for easy inspection. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0023] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-3This utility model provides a technical solution: a bearing wear detection device, including a platform 1, a frame 3 vertically installed on the top of the platform 1, a rectangular tube 5 set on the top of the platform 1, a lifting component set on the top of the rectangular tube 5, a compensation component set inside the rectangular tube 5, a C-shaped body 2 installed on the top of the platform 1, and a fixing component set on the C-shaped body 2.

[0028] The compensation assembly includes springs 13 and lifting bodies 6. Multiple springs 13 are vertically installed at the top of the rectangular tube 5, and the lifting body 6 is slidably inserted into the bottom of the rectangular tube 5. The bottom of each spring 13 is connected to the top of the lifting body 6. A friction roller 14 is rotatably installed at the bottom of the lifting body 6, and a motor 15 is installed on the outer side of the bottom of the lifting body 6. The motor 15 is used to drive the friction roller 14 to rotate.

[0029] Specifically, during workpiece inspection, the workpiece thins due to prolonged friction. Multiple springs 13 installed inside the rectangular cylinder 5 push the lifting body 6 downwards, ensuring the friction roller 14 maintains constant contact with the arc-shaped surface for friction. The inner wall of the rectangular cylinder 5 has multiple vertical guide grooves, each with a sliding block. Each sliding block is mounted on the outside of the lifting body 6, thus restricting its movement. Figure 3 You can tell.

[0030] Furthermore, the lifting assembly includes a first electric push rod 4, which is vertically installed at the top of the frame 3, and a rectangular tube 5 is installed at the output end of the first electric push rod 4.

[0031] Specifically, when it is necessary to bring the friction roller 14 to a position close to the top of the C-shaped body 2, the first electric push rod 4 is activated to drive the rectangular cylinder 5 and its auxiliary components to move downward. By moving the friction roller 14 down to contact the top of the arc-shaped workpiece, the workpiece can be inspected.

[0032] Furthermore, connecting plates 8 are horizontally installed on both sides of the outer side of the rectangular tube 5, and guide rods 7 slide through the connecting plates 8. The top of the guide rods 7 is fixedly installed to the top of the frame 3.

[0033] Specifically, during the up-and-down movement of the rectangular tube 5, the connecting plates 8 installed on both sides of the rectangular tube 5 are slidably connected to the guide rod 7, thereby improving the stability of the up-and-down movement of the rectangular tube 5 and ensuring the stability of the detection.

[0034] Furthermore, the fixing assembly includes a mounting bracket 9, a second electric push rod 10, and a fixing plate 11. Mounting brackets 9 are installed at both ends of the C-shaped body 2, and the second electric push rod 10 is installed inside the mounting bracket 9. The output end of the second electric push rod 10 is installed with a fixing plate 11, and the fixing plate 11 slides through the C-shaped body 2.

[0035] Specifically, after the arc-shaped workpiece is placed into the receiving groove at the top of the C-shaped body 2, the second electric push rod 10 is activated to drive the fixing plates 11 to move closer to each other. The workpiece is then moved to the top two ends of the arc-shaped workpiece by the fixing plates 11, and the workpiece is fixed on the C-shaped body 2 by the fixing plates 11, making it convenient to inspect.

[0036] Furthermore, guide posts 12 are symmetrically installed on the outer side of the fixing plate 11, and the guide posts 12 slide through the mounting frame 9.

[0037] Specifically, after the fixing plates 11 are brought close together to fix the workpiece, the guide posts 12 installed on the fixing plates 11 slide through the mounting bracket 9, thereby improving the stability of the fixing plates 11 and the stability of the fixation.

[0038] The working principle and usage process of this utility model are as follows: When inspecting a workpiece, the workpiece will become thinner due to long-term friction. At this time, multiple springs 13 installed inside the rectangular tube 5 can push the lifting body 6 to move down. After the arc-shaped workpiece is placed into the receiving groove at the top of the C-shaped body 2, the second electric push rod 10 is activated to drive the fixing plates 11 to move closer to each other. The workpiece is transported to the top two ends of the arc-shaped workpiece through the fixing plates 11. The fixing plates 11 clamp out half of the workpiece thickness, thereby fixing the workpiece on the C-shaped body 2 for easy inspection.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
