[0066] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application.

In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0067] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0068] In the automotive industry, the transmission is a core component of the vehicle's drivetrain, and its assembly quality directly affects the vehicle's overall performance, reliability, and service life.

[0069] The assembly process of a transmission involves several complex and critical steps, especially the assembly of the six-shaft system in the middle housing (including but not limited to the differential, input shaft, clutch, and intermediate shaft), which places extremely high demands on assembly precision. The precise installation of these shafts not only affects the transmission efficiency of the transmission but also directly relates to various aspects such as vehicle ride smoothness, noise control, and fuel economy.

[0070] Traditionally, the assembly of the six-shaft system in the gearbox housing has been mainly done manually.

[0071] The specific process includes: First, the operator must manually remove the middle housing and place it stably on the assembly base; then, they must sequentially remove each shaft component, such as the differential, input shaft, clutch, and intermediate shaft, and place them one by one into their corresponding positions on the middle housing based on personal experience and intuition. During this process, the accuracy of the assembly depends almost entirely on the operator's skill level and subjective judgment, lacking objective and quantifiable assembly standards.

[0072] However, this manual assembly method has many drawbacks:

[0073] Low level of automation: The entire assembly process relies heavily on manual labor, with low levels of mechanization and automation, making it difficult to meet the demands of modern automotive manufacturing for efficient and precise production. Difficulty in guaranteeing assembly precision and accuracy: Due to the subjectivity and uncertainty of manual operation, assembly quality can vary significantly between different operators, and maintaining consistent assembly precision over a long period is difficult. Furthermore, the limitations of human perception can easily lead to inaccurate assembly positions, thus affecting the smooth progress of subsequent assembly processes.

[0074] Adjustment is time-consuming: If the shaft position is found to be inaccurate during assembly, manual adjustment is required. This process is not only time-consuming and labor-intensive, but it is also difficult to guarantee that each adjustment will achieve the desired assembly effect.

[0075] High labor costs: The assembly process of the six-axis system of the gearbox housing often requires the collaboration of multiple engineers, which not only increases labor costs, but also places high demands on the professional skills and teamwork ability of the operators.

[0076] In conclusion, traditional manual assembly methods are no longer sufficient to meet the high standards of precision, efficiency, and cost control required for gearbox assembly in the modern automotive manufacturing industry. Therefore, developing a fully automated six-axis assembly and changeover mechanism for the gearbox housing that features high automation, high assembly precision, strong compatibility, and significant reduction in labor costs has important practical significance and application value.

[0077] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0078] like Figures 1-13 As shown, a six-axis assembly system for a gearbox housing includes:

[0079] Truss 1;

[0080] Shaft box fixture changing table 2 is installed on the truss 1 and is used to change fixtures to meet the assembly requirements of different products;

[0081] The middle shell placement platform 3 is located in the middle of the truss 1 and is used to place the middle shell to be assembled;

[0082] A shaft gripping and box-entry device is movably connected to the truss 1 and is used to grip and place the shaft to a designated position.

[0083] Turntable 6, located on one side of the truss 1, is used to provide a loading and transfer position for the shaft system;

[0084] The shaft system tray 7 is installed on the other side of the truss 1 and is used to adjust and fix the shaft system to the assembly position of the corresponding product.

[0085] Truss 1 serves as the skeleton of the entire assembly system, providing stable support and a moving track. It comprises the main frame of Truss 1 and a lateral lifting assembly. The lateral lifting assembly is connected to the main frame of Truss 1 via guide rails and sliders, enabling the horizontal and vertical movement of the shaft gripping and box-entry device. The high rigidity and precise guide rail and slider design of Truss 1 ensure the stability and accuracy of the shaft gripping and box-entry device during movement, providing a foundation for high-precision assembly.

[0086] The shaft assembly clamp changing table 2 is mounted on the truss 1 and includes a changing table main frame 25, a transfer guide slider 26, a transfer plate 27, and a shaft assembly clamp 4 changing tray 32. By moving the transfer guide slider 26 and the transfer plate 27, different shaft assembly clamps 4 can be quickly changed to meet the assembly requirements of different products. This device enables rapid clamp change, significantly improving the flexibility and compatibility of the assembly system, meeting the assembly requirements of various gearbox products, and reducing downtime and costs caused by product changeovers.

[0087] The intermediate housing placement platform 3 is located in the middle of the truss 1 and includes the main frame 29 and the intermediate housing tray 30. The operator places the intermediate housing to be assembled on the intermediate housing tray 30. The tray 30 is fixed in position and easily accessible, facilitating subsequent assembly operations. The design of the intermediate housing placement platform 3 simplifies the positioning and fixing process of the intermediate housing, improves the initial accuracy of assembly, and ensures the precise assembly of the subsequent shaft system.

[0088] The shaft gripping and box-loading device is movably connected to the truss 1, including a shaft gripping mechanism 5 and a shaft box-loading gripper 4. The shaft gripping mechanism 5 grips the shaft from the turntable 6 and then places it onto the shaft box-loading tray 7 via the movement of the truss 1. The shaft box-loading gripper 4 then grips the shaft from the tray 32 and presses it into a designated position within the middle housing. This device achieves automatic shaft gripping and precise box-loading, greatly improving assembly efficiency and accuracy. Simultaneously, the use of precision control components such as the servo press 15 and cylinders ensures more accurate and reliable pressure and position control during the assembly process.

[0089] The turntable 6, located on one side of the truss 1, includes a base 33, a lifting and rotating mechanism 31, and a tray 32. Operators place the shafts to be assembled onto the tray 32. The lifting and rotating mechanism 31, through rotation and lifting actions, moves the shafts to the designated position, facilitating their gripping by the shaft-grabbing and loading device. The turntable 6 automates the loading and transfer of shafts, reducing manual intervention and improving the continuity and efficiency of the assembly process. Simultaneously, its precise rotation and lifting control ensures the accuracy of the shaft positioning.

[0090] The shaft system loading tray 7 is installed on the other side of the truss 1 and includes a loading main frame 71, a transfer guide slider 26, a transfer plate 27, and a six-axis loading tray 74. The six-axis loading tray 74 is equipped with adjustable shaft mounting seats 76 and engaging guide sliders 77, etc., for adjusting and fixing the shaft system to the corresponding product's assembly position. This device, through the adjustable shaft mounting seats 76 and engaging guide sliders 77, achieves precise adjustment and fixing of the shaft system position, ensuring that each shaft system can be accurately assembled into the designated position in the middle housing. At the same time, its strong compatibility allows the device to adapt to the assembly needs of various different products.

[0091] Two transverse lifting components are connected to the main frame of truss 1 via guide rail sliders, and the transverse movement is completed through truss 1. The two transverse lifting components have similar structures and functions. Through assembly with the shaft system loading gripper 4 and shaft system grasping mechanism 5, the mechanism achieves gripping and loading operations at different positions. The following will describe the shaft system loading transverse lifting component 10:

[0092] like Figures 2-3 As shown, the shaft system box entry transverse lifting assembly 10 includes a transverse frame 11, a lifting fixing plate 12, a lifting square tube 13, a lifting guide rail slider 14, a servo press 15, a lifting cylinder 16, a mounting plate 17, a motor 18, a bearing seat 19, a first rotating shaft 20, a guide sleeve 21, a connecting rod 22, a sleeve 23, and a quick change plate 24. The transverse frame 11 is mounted on the guide rail slider of the truss 1, serving as the base for transverse movement. A lifting and fixing plate 12 is installed below it. The lifting and fixing plate 12 is connected to two lifting square tubes 13 through two sets of lifting guide rail sliders 14, serving as the fixed base for lifting. The two lifting square tubes 13 are connected to the mounting plate 17. The mounting plate 17 is equipped with a servo press 15 and a lifting cylinder 16. The servo press 15 and the lifting cylinder 16 realize the lifting of the shaft system entering the box transverse movement lifting assembly 10. A quick-change plate 24 is installed below the mounting plate 17 to realize quick change of the gripper. Two sets of motors 18 are installed above the mounting plate 17. Two sets of bearing seats 19, a first rotating shaft 20, a guide sleeve 21, a connecting rod 22, and a sleeve 23 are installed below the motors 18 in sequence. The input shaft entering the box gripper 56 and the differential shaft entering the box gripper 58 are connected below the two motors 18 to provide the power for rotational engagement of the input shaft and the differential shaft.

[0093] likeFigure 4 As shown, the shaft system loading clamp changing table 2 includes a changing table main frame 25, a transfer guide slider 26, a transfer plate 27, and a shaft system loading clamp 4 changing tray 32. The changing table main frame 25 is installed on the lower left of the truss 1 main frame, serving as the base of the changing table. Two sets of transfer plates 27 are installed on the changing table main frame 25 via the transfer guide slider 26. A set of shaft system loading clamp 4 changing trays 32 is installed above each of the two sets of transfer plates 27 to hold the clamps that need to be replaced. Their initial default positions are on both sides of the changing table main frame 25. When product replacement requires changing the loading clamps, they move to the middle buffer position, and the shaft system loading transverse lifting assembly 10 carries the shaft system loading clamp 4 through the quick-change plate 24 for rapid replacement. The shaft system loading clamp changing table 2 is compatible with the assembly needs of different products by changing the clamps, offering a wide assembly range.

[0094] like Figure 5 As shown, there are two sets of middle shell placement platform 3, including main frame 29 and middle shell tray 30. The main frame 29 is installed in the middle of the lower part of the main frame of truss 1. The middle shell placement platform 3 is the place where the middle shell to be put into the box is placed, and it is also the box entry position of the six shafts and the material picking position after assembly.

[0095] like Figure 6 As shown, the turntable 6 includes a lifting and rotating mechanism 31, a tray 32, and a base 33. The base 33 is the base of the entire mechanism, on which the lifting and rotating mechanism 31 is installed; the tray 32 is placed on the lifting and rotating mechanism 31, and the six axes are lifted by the rotation of the lifting and rotating mechanism 31 to reach the position to be grasped.

[0096] like Figure 7 As shown, the lifting and rotating mechanism 31 includes a lifting base 34, a guide shaft and guide sleeve 35, a lifting plate 36, a slewing bearing base 37, a slewing bearing 38, a rotating bracket 39, a lifting cylinder 40, a rotary motor 41, and a lifting fixture 42. The lifting base 34 and the slewing bearing base 37 are mounted on a base 33. The guide shaft and guide sleeve 35 are mounted above the lifting base 34, serving to guide and support the lifting operation. Each pallet 32 ​​has four sets of these components, making the entire lifting process more stable. The lifting plate 36 is mounted above the guide shaft, and the lifting fixture 42 is mounted above the lifting plate 36. The lifting cylinder 40 drives the lifting fixture 42 to rise and fall. The slewing bearing 38 is mounted above the slewing bearing base 37, and the rotating bracket 39 is connected to the slewing bearing. The slewing bearing 38 drives the rotating bracket 39 to complete the rotation of the lifting and rotating mechanism 31. The use of the slewing bearing 38 ensures the stability and efficiency of the rotation operation. The lifting and rotating mechanism 31 continuously sends the six shafts to different process positions through rotation, ensuring the continuity of assembly work.

[0097] like Figure 8As shown, the pallet 32 ​​includes a pallet base plate 43 and a six-axis support block 44. When the pallet base plate 43 is not lifted, it is placed on the rotating bracket 39. When the rotating bracket 39 rotates the pallet 32 ​​into position, the lifting and rotating mechanism 31 lifts the pallet 32 ​​to the assembly position.

[0098] like Figures 9-11 As shown, the shaft entry jaw 4 is driven by the shaft entry transverse lifting assembly 10, which includes a quick change disc 24 tool side, a main mounting plate 46, a spring 47, a limit post 48, a limit pin 49, a second rotating shaft 50, a main synchronous pulley 51, an idler pulley 52, a jaw mounting plate 53, a synchronous belt 54, a P1 shaft entry jaw 55, an input shaft entry jaw 56, a clutch shaft entry jaw 57, a differential shaft entry jaw 58, an intermediate shaft entry jaw 59, a P3 shaft entry jaw 60, and a driven synchronous pulley 61. The tool side of the quick-change disc 24 works in conjunction with the tool side to achieve quick clamp changes. The tool side of the quick-change disc 24 is connected to the main mounting plate 46. Four sets of springs 47 are installed below the main mounting plate 46. The function of the springs 47 is to buffer and prevent overpressure, so as to avoid damage to the workpiece. Four sets of limiting posts 48 are also installed below the main mounting plate 46. The other end of the spring 47 is connected to the gripper mounting plate 53. Four sets of limiting pins 49 are installed on the gripper mounting plate 53, which work in conjunction with the limiting posts 48 to limit the compression distance of the spring 47. Two sets of second rotating shafts 50 are installed above the gripper mounting plate 53. The hexagonal ends of both shafts are connected to sleeves 23. The other end of one set of second rotating shafts 50 is connected to the main synchronous pulley 51. The main synchronous pulley 51 drives the slave synchronous pulley through the synchronous belt 54. 61 rotates; an idler pulley 52 is also installed between the two synchronous pulleys to mesh with the synchronous belt 54. Its function is to prevent the synchronous belt 54 from loosening and affecting operation after the mechanism has been in operation for a long time; below the synchronous pulley 61 is the input shaft gearbox gripper 56, which verifies whether the shafts can mesh normally by rotating the input shaft; below another set of second rotating shafts 50 is the differential shaft gearbox gripper 58, which verifies whether the differential can mesh normally by rotating; below the gripper mounting plate 53, the P1 shaft gearbox gripper 55, the input shaft gearbox gripper 56, the clutch shaft gearbox gripper 57, the differential shaft gearbox gripper 58, the intermediate shaft gearbox gripper 59, and the P3 shaft gearbox gripper 60 are installed in the required positions to grip the six shafts.

[0099] The shaft gripping mechanism 5 is driven by the shaft gripping lateral lifting assembly 9, and includes a mechanism mounting plate 62, guide pillars 63, gripping jaw mounting plate 64, P-axis jaw, input shaft jaw 66, clutch shaft jaw 67, differential shaft jaw 68, intermediate shaft jaw 69, and P-axis jaw. Four sets of guide pillars 63 are mounted below the mechanism mounting plate 62; the other end of the guide pillars 63 is connected to the gripping jaw mounting plate 64. The P-axis jaw, input shaft jaw 66, clutch shaft jaw 67, differential shaft jaw 68, intermediate shaft jaw 69, and P-axis jaw are installed below the gripping jaw mounting plate 64 in the required positions, gripping six shafts.

[0100] like Figures 12-13 As shown, the shaft system loading tray 7 includes a loading main frame 71, a loading transplant guide slider 72, a loading transplant plate 73, and a six-axis loading tray 74. The main frame 71 for loading into the box is installed on the lower right side of the main frame of the truss 1, serving as the base for the loading platform. Two sets of loading and transplanting plates 73 are installed on the main frame 71 via loading and transplanting guide rail sliders 72. A set of six-axis loading trays 74 are installed above the two sets of loading and transplanting plates 73 to hold six axes. Their initial default positions are on both sides of the main frame 71. When the axis gripping mechanism 5 reaches the top and needs to hold six axes, it moves to the middle buffer position. The axis gripping lateral lifting assembly 9, along with the axis gripping mechanism 5, grips the six axes from the turntable 6 and places them on the six-axis loading trays 74. Then, the axis loading lateral lifting assembly 10, along with the axis loading grippers 4, grips the six axes that have already engaged on the six-axis loading trays 74 and places them into the middle shell at the middle shell placement platform 3.

[0101] The six-axis inlet pallet 74 includes a pallet base plate 43, an axle mounting seat 76, an engagement guide rail slider 77, an engagement moving plate 78, an engagement cylinder 79, a limit assembly 80, a mounting bracket 81, a positioning cylinder 82, a positioning block 83, and a center point 84. The base plate 43 is equipped with shaft mounting seats 76 for the differential shaft and input shaft. These two shafts serve as references and their positions are immovable. The base plate 43 is equipped with four sets of adjustable components, including a meshing guide slider 77, a meshing moving plate 78, a meshing cylinder 79, a limit component 80, a mounting bracket 81, a positioning cylinder 82, a positioning block 83, and a center 84. Each adjustable component is equipped with a shaft whose direction is the same as the meshing direction of the differential shaft and input shaft. The shaft is moved to achieve the meshing state. The adjustable design is compatible with the positions corresponding to different products. The center 84 can reach the middle position of the shaft through the positioning cylinder 82. Its function is to position both ends during the drive of the shaft system to prevent the shaft system from tilting and affecting the meshing of the gears.
