Description
Technical Field
[0001] The utility model relates to the technical field of bearing processing, in particular to a powder metallurgy oil-containing bearing inner hole processing device. Background Art
[0002] Powder metallurgy oil-containing bearings, also known as porous oil-containing bearings or self-lubricating bearings, are a type of bearing material with special structure and performance. They are mainly made by mixing metal powders and other lubricants, pressing them, and then sintering them into parts with a certain porosity. These pores can store lubricating oil and continuously release it during operation, thereby reducing friction, reducing wear, and improving the wear resistance and service life of the bearings. However, due to the characteristics of the powder metallurgy process, the inner hole dimensional accuracy of the directly sintered oil-containing bearings is often not high, and the surface roughness is large, which cannot meet the strict requirements of some precision machinery for the inner diameter dimensional accuracy and surface quality of the bearings. In addition, there may also be deviations in the shape of the inner hole, which affects the matching accuracy and rotational stability of the bearing and the shaft. Traditional processing methods, such as punch extrusion, although they can achieve the processing of the inner hole, may cause cracks, brittle fractures and other problems when processing oil-containing bearings with stepped end faces, which will seriously affect the service life and performance of the bearings. In addition, traditional processing methods usually require manual operation by workers, which not only has high labor costs but also low efficiency. In addition, the inner hole error of the oil-containing bearing may be large during the manufacturing process, which does not meet production requirements, so precise inner hole processing is required. Therefore, a device specifically for subsequent fine processing of the inner hole of the powder metallurgy oil-containing bearing is needed to improve the inner hole size accuracy, improve the surface roughness, and ensure the overall performance and service life of the bearing, so as to achieve efficient and accurate processing of the inner hole of the oil-containing bearing to meet the needs of different application scenarios.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0016] like Figure 1 and Figure 2As shown, a powder metallurgy oil-containing bearing inner hole processing device, the powder metallurgy oil-containing bearing inner hole processing device specifically includes a workbench 1, an extrusion assembly and a bearing moving assembly. The bearing moving assembly is arranged on the side of the workbench 1 through a fixed seat 2. The bearing moving assembly includes a bearing positioning table 3, a moving seat 4, a slide rail 5 and a first motor 6. The bearing positioning table 3 is arranged on the moving seat 4. The moving seat 4 cooperates with the slide rail 5 for movement connection. The slide rail 5 is fixed on the fixed seat 2. The first motor 6 is connected to the moving seat 4. The extrusion assembly includes an extrusion seat 7, a connecting arm 8, an extrusion head 9, a drive shaft 10, a second motor 11 and a lifting assembly. The extrusion seat 7 is arranged on the workbench 1, the connecting arm 8 is arranged on the extrusion seat 7, the lifting assembly is fixed on the connecting arm 8, and a connecting drive shaft 10 is arranged under the lifting assembly. The output shaft of the second motor 11 is connected to the drive shaft 10. A reamer assembly is arranged on the side of the connecting arm 8. During implementation, the workbench 1 has high stability and provides a stable foundation for the entire processing device, ensuring the accuracy and stability during the processing. It can withstand various forces and vibrations generated during the processing to ensure the smooth progress of the processing. The bearing positioning platform 3 on the bearing moving assembly accurately positions the bearing to ensure the stability of the bearing during the processing and improve the processing accuracy. The moving seat 4 cooperates with the slide rail 5 to move and connect to achieve fast and smooth movement of the bearing, thereby improving the processing efficiency. The first motor 6 drives the moving seat 4 to move, thereby realizing automatic transportation of the bearing and reducing the manual operation cost. The extrusion seat 7 and the connecting arm 8 on the extrusion assembly provide stable support for the extrusion head to ensure the accuracy of the extrusion process. The second motor 11 drives the drive shaft 10, thereby driving the extrusion head 9 to perform the extrusion operation to achieve precise processing of the inner hole of the bearing.
[0017] like Figure 1 As shown, on the basis of the above method, the lifting assembly includes a mounting plate 12, a lifting cylinder 13 and a telescopic rod 14. The mounting plate 12 is connected to the connecting arm 8, the lifting cylinder 13 is installed on the side of the mounting plate 12, the telescopic rod 14 is installed at the bottom of the lifting cylinder 13, and the extrusion head 9 is arranged at the end of the telescopic rod 14. In the implementation, the mounting plate 12 is firmly connected to the connecting arm 8, providing a stable support foundation for the entire lifting assembly. This stability ensures that the lifting cylinder 13 and the telescopic rod 14 will not shake or deviate during operation, thereby ensuring the precise position of the extrusion head 9. The lifting cylinder 13 accurately controls the height of the extrusion head 9 through the telescopic rod 14. This high-precision adjustment capability enables the extrusion head 9 to accurately locate the inner hole position of the bearing, thereby achieving precise inner hole processing.
[0018] like Figure 3As shown, further on the basis of the above method, the reamer assembly includes a reamer body 15, a transmission shaft 16, a guide sleeve 17 and a detachable buckle 18. The guide sleeve 17 is arranged on one side of the connecting arm 8 through the detachable buckle 18. The transmission shaft 16 is connected to the guide sleeve 17, and the reamer body 15 is installed at one end, and the other end is connected to the third motor 19. In the implementation, the guide sleeve 17 ensures the stable operation of the transmission shaft 16 to prevent it from offsetting or shaking during the working process. The detachable buckle 18 facilitates the disassembly and installation of the reamer assembly, and is convenient for maintenance and replacement. The third motor 19 provides power for the reamer body 15 to achieve fine processing of the inner hole of the bearing. The design of the detachable buckle 18 makes the disassembly and installation of the guide sleeve 17 and the reamer body 15 convenient and quick. When the reamer assembly needs to be replaced or repaired, the disassembly work can be easily completed by simply loosening the buckle, which reduces the maintenance cost and time cost.
[0019] like Figure 1 As shown, on the basis of the above method, a bearing input channel 20 is further provided on one side of the bearing positioning platform 3, the bearing input channel 20 is higher than the bearing positioning platform 2, and the surface of the bearing input channel 20 is inclined and concave. During implementation, the surface of the bearing input channel 20 is inclined and concave, which facilitates the automatic sliding of the bearing and reduces manual operation. The bearing can smoothly enter the bearing positioning platform 3, thereby improving the efficiency of the entire processing process.
[0020] like Figure 1 As shown, on the basis of the above method, a discharge box 21 is further arranged on the side of the workbench 1. During implementation, the bearings processed in the discharge box 21 can automatically fall into the discharge box 21, thereby reducing the workload of manual handling, avoiding the accumulation of processed bearings on the workbench, and keeping the working area clean and orderly.
[0021] like Figure 1 As shown, on the basis of the above method, a dust suction fan 22 is further arranged on the side of the bearing positioning platform 3. During implementation, the dust suction fan 22 effectively removes the dust and debris generated in the processing process, keeps the working environment clean, prevents dust from polluting or damaging the equipment and bearings, and extends the service life of the equipment and bearings.
[0022] In the specific working process of the processing device of the inner hole of the novel powder metallurgy oil-containing bearing, first, the bearing to be processed is placed on the bearing input channel 20. Since the surface of the bearing input channel 20 is inclined and concave, the bearing can automatically slide onto the bearing positioning platform 3 to realize the automatic positioning and fixing of the bearing. The precise design of the bearing positioning platform 3 ensures the stability of the bearing during the processing and improves the processing accuracy. Next, the first motor 6 is started to drive the moving seat 4 to move on the slide rail 5, thereby driving the bearing on the bearing positioning platform 3 to move to the processing position. This step realizes the rapid and smooth movement of the bearing and improves the processing efficiency. After the bearing reaches the processing position, the lifting assembly starts to work. The lifting cylinder 13 drives the telescopic rod 14 to perform lifting and lowering movements, thereby driving the extrusion head 9 to accurately align with the inner hole position of the bearing. In this process, the mounting plate 12 provides a stable support foundation for the lifting assembly, ensuring the precise position of the extrusion head 9. Subsequently, the second motor 11 is started to drive the drive shaft 10 to rotate, thereby driving the extrusion head 9 to perform the extrusion operation. The extrusion head 9 performs precise processing in the inner hole of the bearing to realize the forming of the inner hole of the bearing. While the extrusion operation is in progress, the reamer assembly also starts working. The third motor 19 drives the transmission shaft 16 to rotate, thereby driving the reamer body 15 to perform fine processing on the inner hole of the bearing. The reamer body 15 is stably mounted on the connecting arm 8 through the guide sleeve 17 and the detachable buckle 18, ensuring the stability and accuracy of the processing process. After the processing is completed, the movable seat 4 moves again on the slide rail 5 to move the processed bearing to the position of the unloading box 21. The bearing automatically falls into the unloading box 21, completing the entire processing process. During the entire processing process, the dust suction fan 22 continues to work, effectively removing the dust and debris generated during the processing process, and keeping the working environment clean. Through the working process of the new powder metallurgy oil-containing bearing inner hole processing device, the automatic and precise processing of the bearing inner hole is realized, the processing efficiency and processing quality are improved, and the manual operation cost is reduced.
