[0002] A "mechanical transmission system" generally refers to a system that transmits power and motion mechanically. It can transfer power from one component to another, achieving coordinated movement between different components. Mechanical transmission systems typically include various transmission methods such as gear drives, belt drives, and chain drives. Each of these transmission methods has its own characteristics and can be selected according to different application requirements. For example, gear drives are suitable for high-precision, high-torque transmission applications; belt drives are suitable for long-distance, low-torque transmission applications. In short, mechanical transmission systems play a crucial role in various mechanical equipment and are a key component for realizing mechanical motion and power transmission.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 5 The image shows an embodiment of this utility model, relating to a bidirectional hydraulically driven assembly device, including a device body 10. The device body 10 includes a base 11, a hydraulic drive module 20, a movable assembly module 30, a pulley positioning frame 40, and a fixed assembly module 50. An assembly platform 12 is provided above the base 11, and an assembly station 13 is provided above the assembly platform 12. One end of the hydraulic drive module 20 faces the assembly station 13 and is used to provide axial thrust to press the pulley 14, bearing (not shown in the figure), and shaft (not shown in the figure). (As shown); the movable assembly module 30 is connected to the hydraulic drive module 20; the pulley positioning frame 40 is located on one side of the movable assembly module 30 to limit the axial displacement of the pulley 14; the fixed assembly module 50 is fixedly connected to the side of the assembly station 13 away from the pulley positioning frame 40; the hydraulic drive module 20, the movable assembly module 30, the pulley positioning frame 40, and the fixed assembly module 50 form a coaxial assembly path on the assembly station 13, so that the hydraulic drive module 20 pushes the bearing (not shown in the figure) to press along the axis of the rotating shaft (not shown in the figure).

[0029] Furthermore, the coaxial assembly path ensures that the pulley 14, bearing (not shown in the figure), and shaft (not shown in the figure) are strictly aligned during press-fitting, reducing assembly deviations and improving overall assembly accuracy; the bidirectional hydraulic drive mode can act on both ends of the component simultaneously, which is more efficient than unidirectional assembly and better suited to the needs of automated production.

[0030] Furthermore, the hydraulic drive module 20 includes a hydraulic cylinder 21 and a support platform 22; the output end of the hydraulic cylinder 21 is connected to the movable assembly module 30; the support platform 22 is fixed to one side above the assembly station 13. Specifically, in the hydraulic drive module 20, the support platform 22 provides a stable mounting base for the hydraulic cylinder 21, reducing vibration and offset during operation and ensuring the stability of the thrust output; the hydraulic cylinder 21, as a power source, can precisely control the thrust magnitude and stroke, which can meet different assembly force requirements, and avoid damage to components due to excessive pressure or incomplete assembly due to insufficient pressure, ensuring controllable press-fit quality.

[0031] Furthermore, the movable assembly module 30 includes a movable platform 31 and a movable pressing cylinder 60; the movable platform 31 is located below the movable pressing cylinder 60; a first clearance groove 61 is provided through the interior of the movable pressing cylinder 60, and a first pressure plate 62 is provided on the side of the movable pressing cylinder 60 near the pulley positioning frame 40, the center of the first pressure plate 62 being connected to the first clearance groove 61. Specifically, in the movable assembly module 30, the first clearance groove 61 of the movable pressing cylinder 60 provides clearance space for the rotating shaft (not shown in the figure), avoiding interference with the rotating shaft (not shown in the figure) during pressing; the contact area between the first pressure plate 62 and the bearing (not shown in the figure) is optimized, which can uniformly transmit hydraulic driving force, push the bearing (not shown in the figure) to be precisely pressed onto the rotating shaft (not shown in the figure) along a preset axis, prevent the bearing (not shown in the figure) from tilting, and improve the coaxiality of the bearing (not shown in the figure) and the rotating shaft (not shown in the figure).

[0032] Furthermore, the pulley positioning frame 40 includes a base 41 and an inclined limiting frame 42. The base 41 is used to fix the inclined limiting frame 42. Two inclined limiting frames 42 are provided, each inclined and fixed to one side of the base 41. An axial limiting area 43, adapted to the shape of the pulley 14, is formed between the two inclined limiting frames 42. Specifically, the pulley positioning frame 40, through the two inclined limiting frames 42, forms an axial limiting area 43 adapted to the shape of the pulley 14, which can precisely limit the axial displacement of the pulley 14 during assembly. It provides a stable positioning reference for the pulley 14 during assembly, preventing subsequent bearings (not shown in the figure) and shafts (not shown in the figure) from deviating from their preset positions due to pulley 14 movement, thus ensuring assembly accuracy from the source. In some embodiments, the pulley positioning frame 40 also includes a locking component for locking the pulley 14 or fixing it to the inclined limiting frame 42 with straps to prevent displacement during assembly.

[0033] Further, the fixed assembly module 50 includes a fixed platform 51, a fixed pressing cylinder 70, and a top plate 52; the fixed platform 51 is located below the fixed pressing cylinder 70; a second clearance groove 71 is provided through the interior of the fixed pressing cylinder 70, and a second pressure plate 72 is provided on the side of the fixed pressing cylinder 70 near the pulley positioning frame 40, the center of the second pressure plate 72 being connected to the second clearance groove 71; the top plate 52 is connected to one end of the fixed pressing cylinder 70. Specifically, in the fixed assembly module 50, the second clearance groove 71 of the fixed pressing cylinder 70 provides clearance space for the rotating shaft (not shown in the figure) to avoid pressing interference; the second pressure plate 72 cooperates with the movable end first pressure plate 62 to realize bidirectional positioning pressing of the double-end bearing (not shown in the figure); the top plate 52 enhances the structural strength of the fixed pressing cylinder 70, prevents module deformation during pressing, ensures accurate pressing position of the fixed end bearing (not shown in the figure), and maintains the stability of the overall assembly structure.

[0034] Furthermore, a guide rail assembly 15 is provided above the assembly platform 12, and the guide rail assembly 15 is slidably connected to the movable platform 31 and the base 41. Specifically, the guide rail assembly 15 includes multiple sets of guide rails. Firstly, during the pressing process, the movable platform 31 and the base 41 can move smoothly along the guide rails through the sliding connection with the guide rails, reducing movement resistance and making it smoother for the hydraulic drive module 20 to push the movable assembly module 30 for pressing, avoiding the pressing position deviation caused by jamming, and ensuring the stability and accuracy of the pressing action. Secondly, by adjusting the position of the base 41 on the guide rails, the spacing or position of the pulley positioning frame 40 can be flexibly adjusted to accurately adapt to the assembly requirements of pulleys 14 of different sizes and specifications. Whether dealing with changes in the diameter of the pulley 14 or differences in the axial installation position, the guide rail can be adjusted for quick positioning, improving the equipment's adaptability to various pulleys 14, expanding the equipment's application range, and ensuring the positioning accuracy of the pulley 14 on the assembly station 13, laying the foundation for the coaxial press-fitting of the bearing (not shown in the figure) and the shaft (not shown in the figure) in the subsequent process.

[0035] Furthermore, the device body 10 also includes a hydraulic station 80, which is connected to the hydraulic drive module 20. The hydraulic station 80 is used to control the extension and retraction movements and thrust of the hydraulic drive module 20. Specifically, the hydraulic station 80, as the control core of the hydraulic drive module 20, can precisely adjust the extension and retraction speed and thrust of the hydraulic cylinder 21. For components of different materials and specifications, optimal pressing parameters can be set to avoid damage to components due to overpressure or assembly failure due to insufficient pressure, achieving precise control of the pressing process and improving assembly quality and reliability.

[0036] Furthermore, the hydraulic station 80 is electrically connected to an electrical control box 81, which is fixedly installed on one side of the support platform 22. Specifically, the electrical control box 81 is electrically connected to the hydraulic station 80 and integrates control circuitry, facilitating operators to set parameters, start or stop the equipment, and perform other operations. The electrical control box 81 enables automated operation of the assembly process, facilitating real-time monitoring and adjustment, and improving the equipment's intelligence and ease of operation. The hydraulic station 80 adopts a conventional structure in the field, including components such as an oil pump, control valve group, and oil tank; its specific structure and working principle will not be described in detail here.

[0037] Furthermore, a base 82 is connected to the bottom of the hydraulic station 80, and the base 82 is located on one side of the assembly platform 12. Specifically, the base 82 increases the support area of ​​the hydraulic station 80, lowers the center of gravity of the equipment, and effectively reduces the vibration and displacement of the hydraulic station 80 during operation. This ensures the stability of the hydraulic system, extends the service life of the equipment, and reduces the impact of the vibration of the hydraulic station 80 on the assembly accuracy.

[0038] Furthermore, two bearings (not shown in the figure) are provided, and the two bearings (not shown in the figure) are respectively connected to both ends of the rotating shaft (not shown in the figure). The two bearings (not shown in the figure) abut against the first pressure plate 62 and the second pressure plate 72 respectively; the rotating shaft (not shown in the figure) is sleeved in the center hole of the pulley 14. Specifically, the abutment relationship between the two bearings (not shown in the figure) and the two pressure plates is clearly defined, as well as the assembly method between the rotating shaft (not shown in the figure) and the pulley 14; the two bearings (not shown in the figure) are synchronously driven and pressed by the two pressure plates to ensure that the force on both ends of the rotating shaft (not shown in the figure) is uniform. After assembly, the rotating shaft (not shown in the figure) has high coaxiality and runs more smoothly; the clear design of component connection relationship ensures the rationality of the assembly structure and ultimately improves the overall operating performance of the equipment.

[0039] The working principle of this utility model is as follows:

[0040] First, the double bearings (not shown in the figure) are respectively fitted onto both ends of the rotating shaft (not shown in the figure), and the rotating shaft (not shown in the figure) is coaxially inserted into the center hole of the pulley 14. The pulley 14 is then placed and fixed on the pulley positioning frame 40. Subsequently, the equipment is started, and the hydraulic station 80 outputs thrust through the hydraulic cylinder 21 of the hydraulic drive module 20, pushing the movable pressing cylinder 60 of the movable assembly module 30 to move towards the assembly station 13. The first pressure plate 62 inside the movable pressing cylinder 60 pushes one end of the bearing (not shown in the figure) to press along the axis of the rotating shaft (not shown in the figure). At the same time, the second pressure plate 72 of the fixed assembly module 50 provides reverse support and positioning for the other end of the bearing (not shown in the figure). The pulley positioning frame 40 restricts the axial displacement of the pulley 14 to ensure its fixed position. Finally, the bidirectional hydraulic drive makes the bearing (not shown in the figure) precisely press onto the rotating shaft (not shown in the figure) along the coaxial path. After the assembly is completed, the hydraulic cylinder 21 retracts, and the assembled part is removed.

[0041] This invention utilizes a hydraulic drive module 20, a movable assembly module 30, a pulley positioning frame 40, and a fixed assembly module 50 to achieve synchronous press-fitting of dual bearings and multi-specification compatibility, significantly improving assembly accuracy and efficiency. Simultaneously, the integrated control of the hydraulic station 80 and the electrical control box 81 ensures that press-fitting parameters can be precisely set, avoiding manual intervention and meeting the demands of industrial production for high-quality, high-reliability assembly.

[0042] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
