Description

TECHNICAL FIELD

[0002] In the machining and manufacturing process of a speed reducer, a bearing needs to be installed on a gear product. Since interference fit is required between the gear and the bearing, a press fitting process is needed for bearing installation. Nowadays, a digital display hydraulic press is usually used to complete the operation, and the specific operation steps are as follows: a worker puts a planetary gear into a press fitting mold with one hand and takes a bearing to put into the press fitting mold with the other hand, then presses the hydraulic press double control switch with both hands at the same time, the hydraulic pressure automatically completes the bearing press fitting, the press fitted gear pops out of the press fitting mold, and finally the worker takes the press fitted speed reducer starter planetary gear bearing and repeats the operation, and this reciprocating cycle is repeated. The traditional press fitting process cannot be applied to a more efficient production line machining. If the traditional press fitting equipment is directly installed on a line body with conveying function, stamping force will be generated on the line body during the press fitting process, which will cause damage to the line body under stress after long-term use. At the same time, the existing press fitting machine has a single use scene and cannot flexibly adjust a more matched press fitting head according to the specifications and sizes of the machined products, so the device has poor universality, which leads to corresponding limitations in the use process of the device, and therefore further improvement is needed.

[0029] In addition, it also needs to be explained that, in the description of the application, unless otherwise explicitly specified and limited, the terms "mounting", "setting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be directly connected, or indirectly connected through intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0030] Embodiment 1: As shown in the figure, the utility model includes a press-fitting mechanism on one side of the wire body 3, the press-fitting mechanism includes a support frame 1, a press-fitting electric cylinder 5 mounted above the support frame 1, a press-fitting plate 6 connected below the press-fitting electric cylinder 5, a press-fitting head 7 below the press-fitting plate 6 and a jacking assembly 4 arranged below the support frame 1, the side of the support frame 1 is provided with a sliding rail, and one side of the press-fitting plate 6 is slidably connected with the sliding rail. The wire body 3 is placed on a tool plate 2, and the jacking assembly 4 can drive the tool plate 2 to move reciprocatingly along the longitudinal direction, so that the tool plate 2 is separated from the wire body 3 or placed on the wire body 3.

[0031] Among them, the jacking assembly 4 includes a positioning plate 15 fixedly connected below the support frame 1, a jacking air cylinder 11 fixedly connected on one side of the positioning plate 15, and a floating bottom plate 13 matched with the jacking air cylinder 11, the positioning plate 15 is provided with a guide rail 14 arranged along the longitudinal direction on the upper side, the floating bottom plate 13 is slidably connected with the guide rail 14, and the jacking air cylinder 11 can drive the floating bottom plate 13 to move reciprocatingly along the longitudinal direction. In the specific implementation process, the jacking air cylinder 11 can be connected with the floating bottom plate 13, during the press-fitting process, the jacking air cylinder 11 pushes the floating bottom plate 13 to lift the tool plate 2 and separate from the wire body 3, so that the wire body 3 is not stressed, avoiding the impact force and continuous pressure during the press-fitting process directly acting on the wire body 3, after the press-fitting is completed, the jacking air cylinder 11 is retracted, the floating bottom plate 13 is lowered, the tool plate 2 is reconnected with the wire body 3, and continues to move with the wire body 3.

[0032] Example 2: Based on Example 1 above, the cooperation between the lifting cylinder 11 and the floating base plate 13 in the lifting assembly 4 can also be achieved in the following way: the lifting cylinder 11 is connected to a drive plate 12, which is slidably connected to the positioning plate 15. When the drive plate 12 moves reciprocally in the horizontal direction, it can drive the floating base plate 13 to move reciprocally in the longitudinal direction. Specifically, a wavy inclined surface 16 is provided at the connection position of the floating base plate 13 and the drive plate 12. When the drive plate 12 moves reciprocally in the horizontal direction, the floating base plate 13 and the drive plate 12, through the cooperation of the wavy inclined surface 16, drive the floating base plate 13 to move reciprocally in the longitudinal direction. With the above-mentioned structure in place, the lifting cylinder 11 pushes the drive plate 12 forward. The drive plate 12 and the floating bottom plate 13 are connected by the wave-shaped inclined surface 16, which can push the floating bottom plate 13 to move upward, thereby lifting the tooling plate 2. After the pressing is completed, the lifting cylinder 11 retracts, the floating bottom plate 13 descends, and the tooling plate 2 is placed back on the line body 3.

[0033] In addition, the bottom surface of the tooling plate 2 in this example is also provided with a positioning groove or positioning pin 17, and the surface of the floating base plate 13 is provided with positioning pin 17 or positioning groove that cooperates with the bottom surface of the tooling plate 2, so that the floating base plate 13 locks itself in position while supporting the tooling plate 2, ensuring concentricity and positional consistency during the pressing process, and reducing external vibration and displacement interference with the pressing effect.

[0034] Example 3: Based on the above example, a pressure head carrier plate can be rotatably connected below the pressure plate 6. Multiple sets of pressure heads 7 are fixedly connected circumferentially below the pressure head carrier plate, and the pressure head carrier plate rotates via a drive motor. In this example, two sets of pressure heads of different models (pressure head a18 and pressure head b19) are arranged circumferentially below the pressure head carrier plate, and the two sets of pressure heads are spaced apart. This allows the rotation to be controlled by the drive motor according to the product model requirements, aligning the appropriate pressure head with the pressure-fitting position of the gear bearing. This provides better compatibility and can be applied to the pressure-fitting needs of gears of different specifications and sizes.

[0035] Furthermore, in this example, a servo motor 9 is preferably used as the drive motor, mounted on the pressing plate 6. The output shaft of the servo motor 9 is connected to a drive gear 10, and a driven gear 8 that meshes with the drive gear 10 is rotatably connected below the pressing plate 6. The pressing head carrier plate is connected to the driven gear 8. The two gears mesh with each other, which can accurately position the pressing position. At the same time, after adjustment, the servo motor 9 stops working. The meshing relationship ensures that the pressing head carrier plate connected to the driven gear 8 does not deflect, ensuring the stability of the pressing process.

[0036] In summary, this invention works in conjunction with the production line during the pressing process. During pressing, the lifting component lifts the tooling plate and detaches it from the production line. After pressing, the tooling plate re-engages with the production line and continues to move with it, achieving asynchronous pressing and conveying operations. This ensures continuous operation of the device and improves overall production efficiency. Simultaneously, during pressing, the lifting component detaches the tooling plate from the production line, which only performs the conveying function. This avoids the impact and continuous pressure during pressing directly acting on the production line, preventing deformation or fatigue damage caused by long-term stress. Furthermore, different types of pressing heads can be installed on the pressing head carrier plate. By rotating, the appropriate pressing head is aligned with the pressing position of the gear bearing. This allows for pressing between different types of gear bearings according to product requirements, demonstrating strong adaptability. It can be used as a standard part in multiple scenarios and has high application and promotion value.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
