For the mounting base for installing the planetary gear reducer, through the setting of the fixing device, after the staff initially fixes the reducer housing, the staff can complete the operations of moving the reducer housing forward and backward and rotating it by pulling the movable plate and rotating the rotating seat, so that the reducer housing can move and rotate to a certain extent while being fixed, which is convenient for the staff to adjust its position during the installation process, reduces the operation of the staff carrying the reducer housing, and improves the work efficiency while reducing the labor intensity of the staff.

[0026] 2. The mounting base for installing the planetary gear reducer enables workers to place three planetary gears in three conduits at one time through the setting of the pressing device.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figures 1 - 4A mounting base for mounting a planetary gear reducer comprises: an operating table 1, a mounting frame 2 is mounted on the operating table 1, a hydraulic cylinder 3 is mounted on the mounting frame 2, and a tool box 8 is mounted on the operating table 1; a pressing device 4 is used to press parts into a reducer housing, the pressing device 4 is arranged on the hydraulic cylinder 3, the pressing device 4 comprises a mounting cylinder 41, the mounting cylinder 41 is mounted on the bottom of the hydraulic cylinder 3, a plurality of rebound telescopic rods 42 are mounted on the bottom of the mounting cylinder 41, a plurality of rebound telescopic rods 42 are connected to a lower pressing cylinder 43 at the bottom, when the staff needs to press the internal parts of the reducer housing, the hydraulic cylinder 3 is started, the hydraulic cylinder 3 drives the mounting cylinder 41 to move downward, the mounting cylinder 41 drives the lower pressing cylinder 43 to move downward through the plurality of rebound telescopic rods 42, the lower pressing cylinder 43 contacts the parts and applies downward pressure to the parts during the downward movement, and the inner of the mounting cylinder 41 is pressed downward by the plurality of rebound telescopic rods 42. Three rubber columns 44 are slidably installed on the lower part, three slide seats 410 are installed inside the pressing cylinder 43, three sliding rings 411 are slidably installed on the three slide seats 410, and three guide tubes 45 are respectively installed on the three sliding rings 411. When the staff needs to install the planetary gear, the planetary gear is placed in the three guide tubes 45 respectively. Due to the certain friction between the guide tubes 45 and the planetary gears, the planetary gears cannot fall out of the guide tubes 45 without being affected by external forces. The three guide tubes 45 are respectively located below the three rubber columns 44. When the installation cylinder 41 moves downward, it drives the three rubber columns 44 to move downward. When the rubber columns 44 move downward, they contact the planetary gears in the guide tubes 45 and push the planetary gears downward, so that the new gears are separated from the guide tubes 45 and pressed down to the installation position by the rubber columns 44, thereby completing the installation of the planetary gears.

[0042] For further information, see Figures 2 - 4 The lower pressure cylinder 43 is internally rotatably installed with a chute turntable 46, on which three arc-shaped chute plates are provided, and three sliding rings 411 are respectively slidably connected with the three arc-shaped chute plates on the chute turntable 46 through rollers, and an adjusting gear 48 is internally rotatably installed with the lower pressure cylinder 43, and a gear ring 47 is installed on the outer wall of the chute turntable 46, and the gear ring 47 is meshed with the adjusting gear 48, and a lever 49 is connected to the adjusting gear 48. The staff manually shifts the lever 49, and the lever 49 drives the adjusting gear 48 to rotate, and the adjusting gear 48 When rotating, the gear ring 47 drives the slide turntable 46 to rotate. When the slide turntable 46 rotates, the three arc-shaped slide grooves on its surface drive the three sliding rings 411 to slide on the three slide seats 410. When the sliding rings 411 slide, they drive the catheter 45 to move synchronously. Since the three sliding rings 411 are arranged in a circular array, the distance of each movement of the three sliding rings 411 is equal. The staff can adjust the center distance of the three sliding rings 411 by toggling the lever 49, thereby realizing the adjustment of the center distance of the three catheters 45.

[0043] With the setting of the pressing device 4, the staff can place three planetary gears in the three conduits 45 at one time, and complete the installation of the three planetary gears by pressing down the three rubber columns 44. Since the installation of three planetary gears can be completed at one time, the work efficiency is improved, and it is avoided that the staff accidentally injure their hands by hitting the planetary gears with a rubber hammer; through the settings of the chute turntable 46, the adjusting gear 48, the chute seat 410, and the sliding ring 411, the staff can adjust the center distance of the conduit 45 according to the planetary gears with different center distances, so as to meet the installation of planetary gears of various specifications of the reducer.

[0044] In this embodiment, the fixing device 5 is used to fix the reducer housing.

[0045] Please refer to Figure 5 , the fixing device 5 is arranged on the operating table 1. The fixing device 5 includes a movable plate 51 which is slidably installed at the bottom of the operating table 1. The staff can complete the adjustment of the front and rear positions of the reducer housing by pulling the movable plate 51. A rotating seat 52 is rotatably installed on the movable plate 51. Since the rotating seat 52 can rotate, the staff can rotate the reducer housing at any time according to the needs. Two damping rods 53 are slidably installed on the rotating seat 52. There is a certain frictional force at the connection between the damping rods 53 and the rotating seat 52, so that the two damping rods 53 simply fix the reducer housing. The staff places the reducer housing to be installed on the rotating seat 52 and manually adjusts the two damping rods 53 to clamp the reducer housing with the two damping rods 53.

[0046] With the setting of the fixing device 5, after the staff initially fixes the reducer housing, they can complete the operations of moving the reducer housing forward and backward and rotating it by pulling the movable plate 51 and rotating the rotating seat 52, so that the reducer housing can move and rotate to a certain extent while being fixed, which is convenient for the staff to adjust its position during the installation process, reduces the operation of the staff carrying the reducer housing, and improves the work efficiency while reducing the labor intensity of the staff.

[0047] Furthermore, please refer to Figures 6 - 7, a centering device 6 for keeping the reducer housing centered; the centering device 6 is arranged on the operating table 1. The centering device 6 includes two force transmission rods 61. Both of the two force transmission rods 61 are slidably installed on the mounting bracket 2. Both of the two force transmission rods 61 are connected to the mounting cylinder 41. A connecting rod 62 is hinged to the bottom of the force transmission rod 61. One end of the connecting rod 62 away from the force transmission rod 61 is hinged to a mounting seat 63. The mounting seat 63 is slidably connected to the operating table 1. A plurality of springs 64 are installed on the mounting seat 63. Two mounting plates 65 are respectively connected to the plurality of springs 64. When the mounting cylinder 41 moves downward, the mounting cylinder 41 drives the two force transmission rods 61 to move downward. The two force transmission rods 61 respectively drive the two mounting seats 63 to move towards each other through the two connecting rods 62. When the mounting seat 63 moves, it drives the two mounting plates 65 to move through the plurality of springs 64. Two curved rods 66 are hinged to the mounting plates 65. Two guide wheels 67 are installed on the curved rods 66. The two mounting seats 63 are arranged in a mirror image. The guide wheels 67 contact the housing of the reducer and apply a certain thrust to the housing of the reducer. Through the cooperation of the four mounting plates 65 and the plurality of springs 64, the eight curved rods 66 and the sixteen guide wheels 67 can apply the same thrust to the four sides of the housing of the reducer, and the mounting plates 65 can adjust their own angles according to the radian of the housing of the reducer.

[0048] Through the arrangement of the centering device 6, before the pressing device 4 contacts the reducer, the four mounting plates 65 clamp the reducer stably through the eight curved rods 66 and the sixteen guide wheels 67, and keep the reducer in the centered position through the same thrust in multiple directions, avoiding the influence on the installation operation caused by the shaking or deviation of the reducer after the pressing device 4 contacts the reducer. Moreover, the four mounting plates 65 can adjust their own angles according to the outer wall shapes of different reducers, increasing the applicability of the centering device 6.

[0049] In this embodiment, a dust cleaning device 7 is used for storing some accessories and cleaning the dust on the accessories.

[0050] Please refer to Figures 8 - 9, the dust cleaning device 7 is arranged on the operation table 1. The dust cleaning device 7 includes a storage seat 71 which is installed on the operation table 1. A plurality of gear racks 72 and a plurality of bearing racks 73 are installed on the storage seat 71. Staff can place the bearings and planetary gears to be installed on the plurality of bearing racks 73 and gear racks 72 on the storage seat 71 in advance. An air bag 74 is installed on the operation table 1. A jet seat 76 is slidably installed on the mounting frame 2. A plurality of nozzles 77 are installed on the jet seat 76. An air inlet pipe 75 is installed on the air bag 74. A one-way valve is arranged inside the air inlet pipe 75. One end of the air inlet pipe 75 far away from the air bag 74 is connected to the jet seat 76. Two ejector rods 78 are hinged on the jet seat 76. One end of each of the two ejector rods 78 far away from the jet seat 76 is hinged to one of the mounting seats 63. The mounting seat 63 can drive the jet seat 76 to move in the vertical direction on the mounting frame 2 through the two ejector rods 78. A pressing block 79 is installed on one of the force transmission rods 61. The air bag 74 is located on the movement track of the pressing block 79. When the force transmission rod 61 installed with the pressing block 79 moves downward, the force transmission rod 61 drives the pressing block 79 to move downward. During the downward movement of the pressing block 79, it contacts the air bag 74 and applies a downward pressure to the air bag 74. After being squeezed, the air bag 74 fills the air inside it into the jet seat 76 through the air inlet pipe 75. The jet seat 76 sprays the air onto the plurality of gear racks 72 and bearing racks 73 through the plurality of nozzles 77.

[0051] Through the arrangement of the dust cleaning device 7, staff can place the bearings and planetary gears on the plurality of bearing racks 73 and gear racks 72 in advance, which is convenient for taking. While the pressing device 4 starts to work, the plurality of nozzles 77 can clean the bearings and planetary gears on the bearing racks 73 and gear racks 72 by jetting air, avoiding a large amount of dust adhering to the surfaces of the bearings and planetary gears after long-term placement. After installation, the dust may cause certain wear to the internal parts of the reducer and reduce the service life of the reducer; through the arrangement of the two ejector rods 78, the jet seat 76 can drive the nozzles 77 to move when the nozzles 77 jet air. By moving the jetting air, the cleaning effect is further improved.

[0052] Working principle: The staff places the reducer housing to be installed on the rotating seat 52 and manually adjusts the two damping rods 53 to clamp the reducer housing with the two damping rods 53. Due to the certain friction at the connection between the damping rod 53 and the rotating seat 52, the two damping rods 53 simply fix the reducer housing. The staff can complete the adjustment of the front and rear positions of the reducer housing by pulling the movable plate 51. Since the rotating seat 52 can rotate, the staff can rotate the reducer housing at any time according to the needs, which is convenient for installation. Through the setting of the fixing device 5, after the staff initially fixes the reducer housing, they can complete the operations of moving the reducer housing forward and backward and rotating it by pulling the movable plate 51 and rotating the rotating seat 52, enabling the reducer housing to move and rotate to a certain extent while being fixed, which is convenient for the staff to adjust its position during the installation process, reducing the operation of the staff carrying the reducer housing, and improving the work efficiency while reducing the labor intensity of the staff.

[0053] When the staff needs to press the internal parts of the reducer housing, the hydraulic cylinder 3 is started. The hydraulic cylinder 3 drives the installation cylinder 41 to move downward. The installation cylinder 41 drives the pressing cylinder 43 to move downward through a plurality of resilient telescopic rods 42. During the downward movement of the pressing cylinder 43, it contacts the parts and applies a downward pressure on the parts. When the staff needs to install the planetary gears, the planetary gears are respectively placed into the three conduits 45. Due to the certain frictional force between the conduits 45 and the planetary gears, the planetary gears cannot fall out of the conduits 45 without being affected by external forces. The hydraulic cylinder 3 is started. The hydraulic cylinder 3 drives the pressing cylinder 43 to move downward through the installation cylinder 41 and a plurality of resilient telescopic rods 42. When the pressing cylinder 43 contacts the parts of the reducer, the pressing cylinder 43 stops moving, and the installation cylinder 41 continues to move downward. When the installation cylinder 41 moves downward, it drives the three rubber columns 44 to move downward. When the rubber columns 44 move downward, they contact the planetary gears in the conduits 45 and push the planetary gears downward, so that the new gears are separated from the conduits 45 and are pressed downward by the rubber columns 44 to the installation position, thus completing the installation of the planetary gears. The installation cylinder 41 can be detachably divided into two parts. There are multiple sets of its lower half part and the connected rubber columns 44, the pressing cylinder 43 and its internal parts. The staff can replace them according to different specifications of the reducer to meet the assembly requirements. When the staff installs planetary gears with different center distances, the staff manually toggles the lever 49. The lever 49 drives the adjusting gear 48 to rotate. When the adjusting gear 48 rotates, it drives the sliding groove turntable 46 to rotate through the gear ring 47. When the sliding groove turntable 46 rotates, it drives the three sliding rings 411 to slide on the three sliding groove seats 410 through the three arc-shaped sliding grooves on its surface. When the sliding rings 411 slide, they drive the conduits 45 to move synchronously. Since the three sliding rings 411 are arranged in a circumferential array, the distance of each movement of the three sliding rings 411 is equal. The staff can adjust the center distance of the three sliding rings 411 by toggling the lever 49, so as to realize the adjustment of the center distance of the three conduits 45. The staff can manually adjust the positions of the three rubber columns 44. When the rubber columns 44 move into the conduits 45, the rubber columns 44 are adjusted to the corresponding positions by the reaction force of the conduits 45, making the positions of the rubber columns 44 more accurate. Through the setting of the pressing device 4, the staff can place the three planetary gears into the three conduits 45 at one time, and complete the installation of the three planetary gears by the downward pressing of the three rubber columns 44. Since the installation of the three planetary gears can be completed at one time, the work efficiency is improved, and it is avoided that the staff accidentally injures their hands by hitting the planetary gears with a rubber hammer. Through the setting of the sliding groove turntable 46, the adjusting gear 48, the sliding groove seats 410 and the sliding rings 411, the staff can adjust the center distance of the conduits 45 according to the planetary gears with different center distances, so as to meet the installation of planetary gears of various specifications of reducers.

[0054] When the installation cylinder 41 moves downward, the installation cylinder 41 drives the two force transmission rods 61 to move downward. The two force transmission rods 61 respectively drive the two mounting seats 63 to move towards each other through the two connecting rods 62. When the mounting seats 63 move, they drive the two mounting plates 65 to move through the multiple springs 64. The mounting plates 65 drive the two curved rods 66 to move. When the curved rods 66 move, the two guide wheels 67 above them contact the housing of the speed reducer and apply a certain thrust to the housing of the speed reducer. Through the cooperation of the four mounting plates 65 and the multiple springs 64, the eight curved rods 66 and the sixteen guide wheels 67 can apply the same thrust to the four sides of the housing of the speed reducer, and the mounting plates 65 can adjust their own angles according to the curvature of the housing of the speed reducer. Through the setting of the centering device 6, before the pressing device 4 contacts the speed reducer, the four mounting plates 65 clamp the speed reducer stably through the eight curved rods 66 and the sixteen guide wheels 67, and keep the speed reducer in the centered position through the same thrust in multiple directions, avoiding affecting the installation operation due to the shaking or deviation of the speed reducer after the pressing device 4 contacts the speed reducer. And the four mounting plates 65 can adjust their own angles according to the outer wall shapes of different speed reducers, increasing the applicability of the centering device 6.

[0055] The staff can place the bearings and planetary gears to be installed on the multiple bearing racks 73 and gear racks 72 on the storage seat 71 in advance, and place the installation tools in the tool box 8 on the operation table 1 for easy taking and placing during the installation process. When the force transmission rod 61 with the pressing block 79 moves downward, the force transmission rod 61 drives the pressing block 79 to move downward. During the downward movement of the pressing block 79, it contacts the airbag 74 and applies a downward pressure to the airbag 74. After being squeezed, the airbag 74 fills the air inside it into the jet seat 76 through the air inlet pipe 75. The jet seat 76 sprays the air onto the multiple gear racks 72 and bearing racks 73 through the multiple nozzles 77, blowing away the dust attached to the surfaces of the bearings and planetary gears on the gear racks 72 and bearing racks 73; when the mounting seat 63 with the ejector rod 78 moves, the mounting seat 63 drives the jet seat 76 to move vertically on the mounting frame 2 through the two ejector rods 78, so that the multiple nozzles 77 on the jet seat 76 can spray air during the movement for cleaning. Through the setting of the dust cleaning device 7, the staff can place the bearings and planetary gears on the multiple bearing racks 73 and gear racks 72 in advance for easy taking. At the same time when the pressing device 4 starts to operate, the multiple nozzles 77 can clean the bearings and planetary gears on the bearing racks 73 and gear racks 72 by jetting air, avoiding a large amount of dust adhering to the surfaces of the bearings and planetary gears after long-term placement. After the installation is completed, the dust may cause certain wear to the internal parts of the speed reducer and reduce the service life of the speed reducer; through the setting of the two ejector rods 78, the jet seat 76 can drive the nozzles 77 to move when the nozzles 77 spray air, and through the way of moving jetting, the cleaning effect is further improved.
