[0066] As Figure 1 shown, Figure 1 is a schematic diagram of a planetary carrier inner and outer ring riveting and pressing system in a small space according to an embodiment of the present invention. The riveting and pressing system includes a fixing plate 1, a lifting slide table mechanism 2, a lifting and rotating mechanism 3, a workpiece pressing mechanism 4, and a floating pressing mechanism 5. Among them, the lifting slide table mechanism 2 is fixedly connected to the fixing plate 1 and is used to drive the riveting and pressing system to perform lifting motion; the lifting and rotating mechanism 3 is arranged between the lifting slide table mechanism 2 and the workbench 6 and is used to fix the workbench 6 and drive the workbench 6 to rotate; the workpiece pressing mechanism 4 is arranged above the workbench 6 and is used to press the workpiece; the floating pressing mechanism 5 is arranged between the lifting slide table mechanism 2 and the lifting and rotating mechanism 3 and is used for pressing the workpiece. As Figure 1 and Figure 2As shown, in this utility model, after the workpiece reaches the workbench 6, the lifting and rotating mechanism 3 is driven by the lifting slide mechanism 2 to move upward, so that the lifting and rotating mechanism 3 is positioned with the workbench 6. The upward movement of the lifting and rotating mechanism 3 causes the workbench 6 to disengage from the turntable 7. The floating press-fitting mechanism 5 rises to the working position inside the workpiece cavity. At this working position, the lifting and rotating mechanism 3 is positioned, and the workpiece pressing mechanism 4 presses the workpiece downward to complete one workpiece press-fitting process. Then, the lifting slide mechanism 2 moves downward, driving the workbench 6 of the workpiece to fall back onto the turntable 7 again. At this position, the workpiece that has been press-fitted will rotate to the next press-fitting position to perform the press-fitting process at the next position. Until all positions have been press-fitted, the lifting and rotating mechanism 3 descends, causing the workbench 6 to fall onto the turntable 7.

[0067] In this embodiment, the structure of the lifting and rotating mechanism 3 can be various structures known to those skilled in the art. In one embodiment of the present utility model, as Figure 3 shown, the lifting and rotating mechanism 3 includes a first fixed bracket 31, a rotating table 32, a positioning pin 33, and a pin positioning block 34. Among them, the rotating table 32 is arranged on the first fixed bracket 31 and is used to drive the workbench 6 to rotate. At least two fixed blocks 35 are arranged on the rotating table 32; the positioning pin 33 is arranged on at least two fixed blocks 35 and is used to position the workbench; the pin positioning block 34 is arranged on one side of the first fixed bracket 31 and is used to fix the rotating table 32. The lifting and rotating mechanism 3 is driven upward by the lifting slide mechanism 2. After the fixed block 35 and the positioning pin 33 position the workbench, the lifting and rotating mechanism 3 lifts upward, causing the workbench 6 to disengage from the turntable 7 until the working position. After reaching the working position, the pin positioning block 34 performs secondary positioning on the workbench 6 to eliminate the clearance of the tooth system. After completing the press-fitting at this position at the working position, this workbench will rotate to the next press-fitting position until all positions have been press-fitted. The lifting and rotating mechanism 3 descends, causing the workbench 6 to fall back onto the turntable 7.

[0068] In this embodiment, the driving motion mechanism of the lifting and rotating mechanism 3 can be various known to those skilled in the art. In one embodiment of the present utility model, the lifting and rotating mechanism 3 further includes a servo drive assembly 36 and a pin positioning cylinder 37. The servo drive assembly 36 is arranged on the other side of the first fixed bracket 31 and is used to rotate the workpiece that has been press-fitted to the next press-fitting position; the pin positioning cylinder 37 is arranged below the pin positioning block 34. After the positioning pin 33 performs primary positioning with the workbench 6, the pin positioning cylinder 37 drives the pin positioning block 34 to perform secondary positioning with the workbench 6.

[0069] In this embodiment, the structure of the lifting slide mechanism 2 can be various structures known to those skilled in the art. In one embodiment of the present utility model, as Figure 4As shown in the figure, the lifting and sliding table mechanism 2 includes: a second fixed bracket 21, a first guide rail slider 22, a lifting and sliding table 23, and a limit dead stop 24. Among them, the bottom of the second fixed bracket 21 is connected to the fixed plate 1, and a first guide rail 25 is provided on the side of the second fixed bracket 21 close to the workbench 6; the first guide rail slider 22 is slidably arranged on the first guide rail 25; the lifting and sliding table 23 is connected to the first guide rail slider 22; the limit dead stop 24 is arranged above the side of the second fixed bracket 21 close to the workbench 6 for adjusting the rising speed of the lifting and sliding table 23. The first guide rail 25 is a linear guide rail, and the lifting and sliding table 23 can move vertically on the first guide rail 25. The first guide rail 25 ensures the accuracy of the running direction of the lifting and sliding table 23. The limit dead stop 24 is composed of a hydraulic buffer and a mechanical stop block, and by adjusting the limit dead stop 24, the rising speed of the lifting and sliding table 23 can be ensured.

[0070] In this embodiment, for the driving motion mechanism of the lifting and sliding table mechanism 2, there can be various types known to those skilled in the art. The driving motion mechanism of the lifting and sliding table mechanism 2 includes a lifting cylinder 26 and a balance cylinder 27. Among them, the lifting cylinder 26 is arranged on the side of the second fixed bracket 21 away from the workbench 6 for driving the lifting and sliding table 23 to perform lifting motion; the balance cylinder 27 is arranged on the side of the second fixed bracket 21 close to the workbench 6 for fixing the lifting and sliding table 23. The lifting cylinder 26 drives the lifting and sliding table 23 to move vertically on the first guide rail 25; the locked balance cylinder 27 ensures that in the case of air cut-off, the riveting and pressing system can still be fixed on the first guide rail 25, eliminating the hidden danger of the free fall of the lifting and sliding table 23.

[0071] In this embodiment, for the structure of the workpiece pressing mechanism 4, there can be various structures known to those skilled in the art. In an embodiment of the present invention, as Figure 5 shown, the workpiece pressing mechanism 4 includes a third fixed bracket 41, a pressing block 42, and a pressing cylinder 43. Among them, the third fixed bracket 41 is connected to the fixed plate 1; the pressing block 42 is arranged at one end of the third fixed bracket 41 close to the workbench 6 for pressing the workpiece; the pressing cylinder 43 is arranged above the pressing block 42 and is connected to the pressing block 42 for driving the pressing block 42 to press the workpiece. When the workpiece is at the working position, the pressing cylinder 43 extends to press the pressing block 42 against the workpiece so that the workpiece will not move during the pressing process.

[0072] In this embodiment, for the structure of the floating pressing mechanism 5, there can be various structures known to those skilled in the art. In an embodiment of the present invention, as Figure 6As shown, the floating press-fitting mechanism 5 includes a floating press-fitting body 51, a second guide rail 52, a second guide rail slider 53, a servo press-fitting assembly 54, and a floating assembly 55. Among them, the floating press-fitting body 51 is arranged between the lifting and slewing mechanism 3 and the lifting slide table mechanism 2, and is elastically connected to the lifting slide table mechanism 2. A press head 56 is provided at the end of the floating press-fitting body 51 close to the workbench for press-fitting workpieces. The second guide rail 52 is arranged on one side of the floating press-fitting body 51 close to the lifting and slewing mechanism 3. The second guide rail slider 53 is slidably arranged on the second guide rail 52. The servo press-fitting assembly 54 is fixedly connected to the second guide rail slider 53 and is used to cooperate with the press head 56 to clamp the workpiece. The floating assembly 55 is arranged to slide relative to the floating press-fitting body 51, and the floating assembly 55 is fixedly connected to the lifting slide table mechanism 2. Through the floating assembly 55, relative sliding is generated between the floating press-fitting mechanism 5 and the lifting slide table 23, so that the press head can move and clamp the workpiece during press-fitting.

[0073] In this embodiment, the floating press-fitting mechanism 5 further includes a spring assembly 57 for connecting the floating press-fitting body 51 and the floating assembly 55. As Figure 7 and Figure 8 shown, the spring assembly 57 is a return spring. The entire floating press-fitting mechanism 5 moves along with the lifting slide table mechanism 2. At the initial position, the spring assembly 57 is in a compressed state. When providing a thrust to the floating press-fitting body 51, the floating press-fitting body 51 moves to the limit dead point on the second guide rail 52. At this time, the center of the press head 56 is offset from the center of the workpiece, so that the press head 56 can smoothly enter the cavity of the workpiece during the lifting process. At the working position, when the press head 56 presses on the workpiece, due to the action of the reverse force, the floating press-fitting body 51 will drive the press head 56 to move in the reverse direction on the second guide rail 52, and the press head 56 inside the workpiece will move to the working position to clamp the workpiece. At this time, the spring assembly 57 continues to be compressed. After the workpiece at the working position is press-fitted, the spring assembly 57 releases its elastic force and drives the floating press-fitting body 51 to move. At this time, the press head 56 disengages from the workpiece, and the center of the press head 56 is offset from the center of the workpiece, which can ensure that it does not interfere with the workpiece when descending.

[0074] Through the above technical solution, after the workpiece reaches the workbench 6, the lifting and rotating mechanism 3 is driven by the lifting slide mechanism 2 to move upward, so that the lifting and rotating mechanism 3 is positioned with the workbench 6. The upward movement of the lifting and rotating mechanism 3 causes the workbench 6 to disengage from the turntable 7. The floating press-fitting mechanism 5 rises to the working position inside the workpiece cavity. At this working position, the lifting and rotating mechanism 3 is positioned, and the workpiece pressing mechanism 4 presses the workpiece downward to complete a workpiece press-fitting process. Then, the lifting slide mechanism 2 moves downward, driving the workbench 6 of the workpiece to fall back onto the turntable 7 again. At this position, the workpiece that has completed the press-fitting will rotate to the next press-fitting position to perform the press-fitting process at the next position. Until all the press-fittings at all positions are completed, the lifting and rotating mechanism 3 descends, causing the workbench 6 to fall onto the turntable 7.

However, the implementation manners of the present invention are not limited to the specific details in the above implementation manners. Within the technical concept scope of the implementation manners of the present invention, various simple modifications can be made to the technical solutions of the implementation manners of the present invention, and these simple modifications all belong to the protection scope of the implementation manners of the present invention.

[0076] In addition, it should be noted that, among the various specific technical features described in the above specific implementation manners, they can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention implementation manners will not separately describe various possible combination manners.

[0077] Furthermore, any combination can be made among the various different implementation manners of the present invention implementation manners, as long as it does not violate the idea of the present invention implementation manners, and it should also be regarded as the content disclosed by the present invention implementation manners.
