Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an automotive drive shaft processing platform. Background Technology

[0002] The driveshaft is a key component of the automotive powertrain system. Its function is to efficiently and smoothly transmit the torque output from the engine or transmission to the drive axle. The driveshaft is usually welded or assembled from components such as shaft tube, universal joint fork, and sliding spline. Its processing involves multiple key steps such as blanking, cutting, welding, heat treatment, dynamic balancing, and surface treatment. The driveshaft processing platform is the specialized equipment or integrated work area that supports and realizes these steps. Its rational design, completeness of functions, and ease of operation directly determine the processing accuracy, production efficiency, and final product quality of the driveshaft. An efficient and reliable processing platform is crucial for ensuring the performance and lifespan of the driveshaft, as well as the safety and comfort of the entire vehicle operation.

[0003] However, in the manufacturing process of drive shafts, especially before welding, heat treatment, or spraying, thorough cleaning of the inner and outer surfaces of the shaft tube and the welding area is a key prerequisite for ensuring the quality of subsequent processes and the reliability of the product. Existing machining platforms or their associated cleaning processes generally suffer from incomplete cleaning: on the one hand, traditional manual cleaning methods (such as manual grinding and blowing) are inefficient and cannot guarantee cleanliness, especially for removing residues (such as oxide scale, welding slag, oil, and dust) inside the shaft tube, in welding dead corners, and in complex contour areas; on the other hand, even when using automated cleaning equipment, the cleaning effect is often unstable and there are missed areas due to low integration with the machining platform, unreasonable cleaning station design, incomplete coverage of cleaning media (such as airflow and abrasive), or inaccurate parameter control.

[0004] Therefore, how to provide a machining platform for automotive drive shafts is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide an automotive driveshaft processing platform, which solves the problems mentioned in the background art.

[0006] An automotive drive shaft processing platform according to an embodiment of the present invention includes a placement frame and a shaft body. A shaft mounting component is provided on the inner side of the placement frame. Both ends of the shaft body are movably engaged with one end of the shaft mounting component. A reciprocating lead screw is rotatably connected to the inner side of the placement frame. A guide rod parallel to the reciprocating lead screw is also fixedly connected to the inner side of the placement frame. A reciprocating movable seat is movably sleeved on the surface of both the guide rod and the reciprocating lead screw. A positioning ring is fixedly connected to the end face of the reciprocating movable seat. The positioning ring is movably sleeved on the surface of the shaft body. A cleaning component is provided inside the positioning ring. The inner wall of the cleaning component is movably connected to the surface of the shaft body.

[0007] The shaft mounting component includes a positioning shaft, a positioning block, a threaded knob, and a positioning cone. The positioning shaft is fixedly installed on the inner side of the placement frame, the positioning block is fixedly connected to the surface of the positioning shaft, the positioning cone is movably sleeved on the surface of the positioning shaft through the positioning block, the threaded knob is threadedly sleeved on the surface of the positioning shaft, and one side of the positioning cone is movably connected to one side of the threaded knob. The end face of the positioning cone is movably engaged with the end face of the shaft.

[0008] The diameter of the positioning cone is smaller than the diameter of the cleaning component but larger than that of the shaft.

[0009] The cleaning component includes a rotating ring, an arc-shaped through groove, a cleaning ring, and an annular tooth. The rotating ring is rotatably connected to the inner wall of the positioning ring, the cleaning ring is fixedly installed on the inner side of the rotating ring, the inner side of the cleaning ring is movably connected to the surface of the shaft, the annular tooth opens and closes on the side of the rotating ring, and the arc-shaped through groove is formed on the surface of the positioning ring.

[0010] The guide rod has a row of toothed grooves on its surface. One side of the positioning ring is rotatably connected to a first rotating shaft via a first positioning seat. One end of the first rotating shaft is fixedly connected to a transmission gear. The transmission gear passes through an arc-shaped through groove and meshes with a ring tooth. The other end of the first rotating shaft is fixedly connected to a first bevel gear. A second bevel gear meshes with the first bevel gear. One side of the second bevel gear is fixedly connected to a second rotating shaft. The second rotating shaft is rotatably connected to the surface of the reciprocating movable seat via a second mounting seat. The other end of the second rotating shaft is fixedly connected to a movable gear. The movable gear meshes with the row of toothed grooves.

[0011] A drive motor is fixedly installed on the side of the placement rack, and the output shaft of the drive motor is fixedly connected to the end face of the reciprocating lead screw.

[0012] The beneficial effects of this utility model are:

[0013] During the machining of the drive shaft, the cleaning ring rotates synchronously with the reciprocating motion, continuously and automatically cleaning the surface of the shaft, removing debris, oil stains and other impurities generated during machining, significantly improving cleaning efficiency and effectiveness, reducing manual intervention and downtime, and improving machining quality and efficiency.

[0014] The shaft mounting components (locating shaft, locating block, threaded knob, locating cone) are uniquely designed. By turning the threaded knob, the position of the locating cone on the locating shaft can be flexibly adjusted, allowing it to precisely engage and clamp the end face center of shafts of different sizes (such as spline ends), providing stable and reliable clamping force and strong adaptability. The diameter design of the locating cone (smaller than the diameter of the cleaning part but larger than the diameter of the shaft) ensures that it will not extend into the working area of ​​the cleaning part when clamping the shaft end, avoiding obstruction or damage to the cleaning action.

[0015] The rotational power of the cleaning component does not come from an additional motor, but rather from a cleverly designed gear transmission mechanism (moving gear, continuous toothed groove, bevel gear set, transmission gear, and ring gear) that automatically converts the linear motion of the reciprocating seat along the guide rod into the rotational motion of the cleaning ring. This design makes full use of the existing reciprocating motion, eliminates the need for an additional power source, simplifies the structure, and reduces cost and energy consumption.

The threaded knob 11 is threadedly sleeved on the surface of the positioning shaft 9, and one side of the positioning cone 12 is movably connected to one side of the threaded knob 11. The end face of the positioning cone 12 is movably engaged with the end face of the shaft 2. The diameter of the positioning cone 12 is smaller than the diameter of the cleaning component 8 but larger than the diameter of the shaft 2.

[0024] refer to Figure 1-4 In this embodiment, the two ends of the shaft 2 are respectively movably engaged with one end of the shaft mounting component 3. The inner side of the placement frame 1 is rotatably connected to the reciprocating lead screw 4. The inner side of the placement frame 1 is also fixedly connected to the guide rod 5 parallel to the reciprocating lead screw 4. The surfaces of the guide rod 5 and the reciprocating lead screw 4 are movably sleeved with reciprocating movable seats 6. The end face of the reciprocating movable seat 6 is fixedly connected to the positioning ring 7. The positioning ring 7 is movably sleeved on the surface of the shaft 2. The cleaning component 8 includes a rotating ring 13, an arc-shaped through groove 14, a cleaning ring 15, and an annular tooth 16. The rotating ring 13 is rotatably connected to the inner wall of the positioning ring 7. The cleaning ring 15 is fixedly installed on the inner side of the rotating ring 13. The inner side of the cleaning ring 15 is movably connected to the surface of the shaft 2. The annular tooth 16 opens and closes on the side of the rotating ring 13. The arc-shaped through groove 14 is opened on the surface of the positioning ring 7.

[0025] refer to Figure 1-4 In this embodiment, a cleaning component 8 is provided inside the positioning ring 7. The inner wall of the cleaning component 8 is movably connected to the surface of the shaft 2. A drive motor 21 is fixedly installed on the side of the placement frame 1. The output shaft of the drive motor 21 is fixedly connected to the end face of the reciprocating lead screw 4.

[0026] refer to Figure 1-4In this embodiment, the surface of the guide rod 5 is provided with a row of toothed grooves 17. One side of the positioning ring 7 is rotatably connected to a first rotating shaft through a first positioning seat. One end of the first rotating shaft is fixedly connected to a transmission gear 18. The transmission gear 18 passes through the arc-shaped through groove 14 and meshes with the ring gear 16. The other end of the first rotating shaft is fixedly connected to a first bevel gear 19. A second bevel gear 20 meshes with the first bevel gear 19. One side of the second bevel gear 20 is fixedly connected to a second rotating shaft. The second rotating shaft is rotatably connected to the surface of the reciprocating movable seat 6 through a second mounting seat. The other end of the second rotating shaft is fixedly connected to a movable gear 22. The movable gear 22 meshes with the row of toothed grooves 17.

[0027] The working principle of this utility model is as follows:

[0028] Both ends of the shaft 2 are movably engaged with the positioning cones 12 of the two side shaft mounting parts 3 through the center of their end faces. By turning the threaded knob 11, the positioning cones 12 can be moved along the positioning shaft 9, thereby clamping or loosening the ends of the shaft 2 to achieve a stable clamping. During processing, the drive motor 21 drives the reciprocating movable seat 6 on its surface through the rotation of the reciprocating lead screw 4. At the same time, the guide rod 5 guides the reciprocating movable seat 6 to make linear reciprocating motion in a direction parallel to the shaft 2. The positioning ring 7 fixed on the reciprocating movable seat 6 moves accordingly, and the cleaning ring 15 sleeved on the surface of the shaft 2 also moves synchronously. During the reciprocating motion, the movable gear 22 fixed on the reciprocating movable seat 6 meshes with the row of toothed grooves 17 opened on the surface of the guide rod 5, which will move the shaft 2 towards the reciprocating position. The linear motion of the reciprocating seat 6 is converted into the forward and reverse rotational motion of the movable gear 22. This rotational motion is transmitted to the second bevel gear 20 through the second rotating shaft, and then to the first rotating shaft through the first bevel gear 19 that meshes with it. Finally, it drives the transmission gear 18 to rotate. The transmission gear 18 passes through the arc-shaped through groove 14 on the positioning ring 7 and meshes with the ring tooth 16 on the side of the rotating ring 13 of the cleaning component 8. This causes the rotating ring 13 and the cleaning ring 15 inside it to rotate around the surface of the shaft 2. Therefore, during the entire processing, the cleaning ring 15 not only moves back and forth along the length of the shaft 2 with the reciprocating seat 6, but also rotates continuously, achieving 360-degree dynamic cleaning of the surface of the shaft 2 without dead angles.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
