Description

Technical Field

[0001] The present invention relates to the technical field of gear assembly of a reducer, and more specifically, to a gear continuous assembly device for a reducer and a working method thereof. Background Art

[0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. It can reduce the speed of the electric motor, internal combustion engine or other high-speed power source, and increase the output torque to meet various work requirements. The reducer gear is assembled in the gearbox and is the core transmission component of the reducer. Through the meshing of gears with different numbers of teeth, the input high-speed and low-torque power is converted into the output low-speed and high-torque power.

[0003] At present, there are two main ways to assemble the gears of reducers: manual assembly and automated assembly. The automated assembly method relies on the gripper technology, which clamps the gears and rotates them to achieve automatic positioning and assembly. This process is efficient and accurate. The other method is the traditional manual installation of gears, which relies on the skills and experience of the operator to complete.

[0004] The method of automatic gear installation is mainly suitable for gearboxes with relatively spacious space. For those gearboxes with relatively narrow space, manual installation has to be relied upon. If manual installation is used, the efficiency and operability of gear assembly will be greatly limited. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a gear continuous assembly device for a reducer and a working method thereof.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gear continuous assembly device for a reducer, comprising a conveying component and a processing component and a positioning component installed on the top of the conveying component, the conveying component comprising a base, and the positioning component is arranged above the base.

[0007] A fixing seat is arranged above the base, and a first fixing component and two groups of second fixing components are arranged on the top surface of the fixing seat.

[0008] The processing assembly includes a lifting electric slide rail installed on the top of the base and a lifting platform slidably connected to one side of the lifting electric slide rail, and a driving mechanism is arranged on one side of the lifting platform.

[0009] An assembly component is arranged at the output end of the driving mechanism, and the assembly component includes a ring body penetrating the output end of the driving mechanism, and two conical blocks are arranged at one end of the ring body, and the outer side walls of the two conical blocks are provided with sliding grooves, and the inside of the sliding groove is slidably connected with a slider, and a three-jaw chuck is concentrically installed on the side wall of the output end of the driving mechanism away from the ring body.

[0011] By adopting the above technical solution, after the first set of gears is assembled, the second set of gears is clamped by a three-jaw chuck, the conical block clamps the rotating shaft, the slider spacing is adjusted to be the same as the gear tooth spacing, and the processing component drives it close to the housing. During this period, the driving mechanism causes the ring body and the tube body to rotate slightly forward and reverse, and the conical block drives the gears and the rotating shaft to rotate, first fitting with the first set of gear teeth, and then the two sliders are aligned. After alignment, the driving mechanism stops, and the extrusion cylinder pushes the extrusion rod to connect with the rotating shaft and push the second set of gears and the rotating shaft to move, completing the meshing with the first set of gears. This operation is suitable for automatic assembly of small space gearboxes.

[0013] By adopting the above technical solution, the fixing plate is used to place the main part of the gear box housing, and the locking mechanism fixes the main part of the housing. The locking mechanism is composed of a screw, a nut, and a clamping component. The staff manually rotates the screw, and the clamping component moves along the screw, thereby clamping or releasing the main part of the housing. The lifting cylinder is used to push the fixing plate and the main part of the housing up and down, thereby adjusting the height of the main part of the housing to meet the assembly conditions.

[0014] The present invention is further configured such that two groups of the second fixing components are respectively arranged on both sides of the first fixing component, and the two groups of the second fixing components each include a sliding table slidably connected to the top of the track and a bracket installed on the top of the corresponding sliding table, a driving motor is horizontally installed on one side of the bracket, the output end of the driving motor is connected to a connecting rod, and the outer side wall of the connecting rod is installed with a flip plate for positioning the gear box housing.

[0015] By adopting the above technical solution, after the gear assembly is completed, one group of the second fixing components drives the end cover to swing to a vertical state and approach the direction of the first fixing component, thereby completing the assembly of one end cover and the outer shell body, and then the positioning component is separated from the outer shell body, and the other end cover is also swung to a vertical state and assembled with the outer shell body.

[0016] The present invention is further configured such that the positioning assembly includes a positioning electric slide rail installed on the top of the platform, the extension direction of the positioning electric slide rail is the same as the extension direction of the first electric slide rail, the top of the positioning electric slide rail is slidably connected with a positioning seat, the top of the positioning seat is horizontally installed with a positioning cylinder, the extension direction of the positioning cylinder piston rod is the same as the extension direction of the second electric slide rail, a vertical plate is vertically installed at the end of the piston rod of the positioning cylinder, and a positioning plate is installed on one side of the vertical plate.

[0017] The present invention is further configured such that a plurality of through holes are opened on one side of the positioning plate, and an aperture clamping mechanism is installed on the side wall of the positioning plate and at a position corresponding to each through hole.

[0018] The present invention is further configured such that a rotating cylinder is installed on one side of the lifting platform, the output end of the rotating cylinder is connected to the driving mechanism, the assembly component also includes an extrusion cylinder installed on the side wall of the driving mechanism, the piston rod end of the extrusion cylinder is connected to an extrusion rod, and the extrusion rod is coaxially arranged with the ring body.

[0019] The present invention is further configured such that a tube body is provided between the ring body and the three-jaw chuck, a mounting plate is connected between the tube body and the ring body, the top and bottom of the mounting plate are swingably connected with swing arms, the swing arms are respectively hinged to the relative end positions of the ring body and the tube body, and the hinge points are connected to torsion springs, the two swing arms are arranged corresponding to the two conical blocks, and the ends of the swing arms are connected to the corresponding conical blocks.

[0020] The present invention is further configured such that a telescopic rod is installed on one side of the mounting plate close to the conical block, the end of the telescopic rod passes through the mounting plate and is connected to a guide rail, two guide blocks are slidably connected to the side walls of the guide rail, the two swing arms are arranged corresponding to the two guide blocks, and one end of the swing arm away from the conical block is hinged to the end of the corresponding guide block.

[0021] By adopting the above technical solution, the gears are assembled continuously with the help of the processing components and the assembly components. When assembling the second set of gears, the two conical blocks are pre-aligned with the first set of gears. After completion, the telescopic rod is retracted, driving the guide rail and the guide block to move, squeezing the swing arm to make it swing, and then the conical block is separated and moved between the ring body and the tube body. Subsequently, the second set of gears is pushed by the squeezing rod and meshed with the first set of gears. This method can realize automatic assembly, and the conical block is detachable and does not interfere with the end cover.

[0022] By setting the positioning assembly, the positioning electric slide rail drives the positioning seat, positioning cylinder, vertical plate and positioning plate to approach the shell body. Then, the positioning cylinder pushes the vertical plate and positioning plate to make the positioning plate fit one side of the shell body. At this time, the first set of gear rotating shafts are aligned with the through holes on the side wall of the positioning plate. Then the extrusion cylinder pushes the extrusion rod to move the first set of rotating shafts and gears. The shafts are inserted into the corresponding through holes and fixed by the aperture clamping mechanism. The second set of gears and rotating shafts are also positioned with the positioning plate after assembly. This not only ensures the stability of the gear assembly when the end cover is not installed, but also further prevents interference from the conical block because the shell body is through.

[0023] A method for continuously assembling gears for a reducer, using the above-mentioned continuous assembly device for gears for a reducer, comprises the following steps:

[0024] S1. The main part and two end cover parts of the gear box housing are respectively placed on the first fixing component and two groups of second fixing components and fixed by the housing transfer robot. Then the two groups of second fixing components respectively drive the corresponding end covers to swing to a horizontal state. At the same time, the first fixing component drives the housing body to rise to a certain height. During this process, the gear transfer robot passes the first group of gears with rotating shafts through the interior of the ring body, and the rotating shafts are clamped by a three-jaw chuck.

[0025] S2. After the preparation work is completed, the conveying component drives the shell body and the end cover to move synchronously to the assembly position, and the lifting electric slide rail drives the lifting platform to move downward, causing the gear to move to the side wall position of the shell body, and then the positioning component is fitted with one side of the shell body, and the first set of gears and the rotating shaft are aligned with the positioning component and the shell body to complete the placement.

[0026] S3. The processing assembly is then reset, and the gear transfer robot places the second set of gears and clamps them through the three-jaw chuck. At this time, the two conical blocks clamp the rotating shaft, and the spacing between the two sliders is adjusted to the same position as the spacing between the gear teeth. Then the processing assembly drives the second set of gears and the rotating shaft to approach the main body of the shell again. In this process, the driving mechanism is first used to drive the ring body and the tube body to rotate slightly forward and backward. The conical surfaces of the two conical blocks first fit with the first set of gear teeth inside the main body of the shell, and then the two sliders gradually align with the first set of gear teeth. After the alignment is completed, the driving mechanism stops rotating, and the second set of gears enters the main body of the shell.

[0027] S4. Then the two conical blocks are separated, the processing assembly is reset, the gear transfer robot places the third set of gears again and clamps them through the three-jaw chuck, and the next alignment assembly is completed through the step of S3.

[0028] S5. After the gear assembly is completed, one set of the second fixing components drives the end cover to swing to a vertical state and approaches the direction of the first fixing component, thereby completing the assembly of one end cover and the shell body. Subsequently, the positioning component is separated from the shell body, and the other end cover is also swung to a vertical state and assembled with the shell body.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] (1) By setting a conical block, after the first set of gears is assembled, the second set of gears is clamped by a three-claw chuck, the conical block clamps the rotating shaft, the slider spacing is adjusted to the same as the gear tooth spacing, and the processing assembly drives it close to the housing. During this period, the driving mechanism causes the ring body and the tube body to rotate slightly forward and backward. The conical block drives the gear and the rotating shaft to rotate, first fitting with the first set of gear teeth, and the two sliders are aligned in the assembly movement direction. After alignment, the driving mechanism stops, the extrusion cylinder pushes the extrusion rod to connect with the rotating shaft and pushes the second set of gears and the rotating shaft to move, completing the meshing with the first set of gears. This operation is suitable for automatic assembly of small space gearboxes.

[0031] (2) The gears are assembled continuously with the help of processing components and assembly components. When assembling the second set of gears, the two conical blocks are pre-aligned with the first set of gears in the assembly moving direction. After completion, the telescopic rod is retracted, driving the guide rail and the guide block to move, squeezing the swing arm to make it swing, and then the conical block is separated and moved between the ring body and the tube body. Subsequently, the second set of gears is pushed by the squeezing rod and meshed with the first set of gears for assembly. This method can realize automatic assembly, and the conical block is detachable and does not interfere with the end cover.

[0032] (3) By setting the positioning assembly, the positioning electric slide rail drives the positioning seat, positioning cylinder, vertical plate and positioning plate to approach the shell body. Then, the positioning cylinder pushes the vertical plate and positioning plate to make the positioning plate fit the side of the shell body. At this time, the first set of gear rotating shafts are aligned with the through holes on the side wall of the positioning plate. Then, the extrusion cylinder pushes the extrusion rod to move the first set of rotating shafts and gears. The shafts are inserted into the corresponding through holes and fixed by the aperture clamping mechanism. The second set of gears and rotating shafts are also positioned with the positioning plate after assembly. This not only ensures the stability of the gear assembly when the end cover is not installed, but also further prevents interference from the conical block because the shell body is through.

[0050] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0051] See also Figure 1-9 , the present invention provides the following technical solutions:

[0052] Embodiment 1, a gear continuous assembly device for a reducer, comprises a conveying assembly 1 and a processing assembly 2 and a positioning assembly 3 installed on the top of the conveying assembly 1, the conveying assembly 1 is used to position the gear box of the reducer, the processing assembly 2 is used to clamp and transfer the gear, when the gear and the gear box are assembled, the positioning assembly 3 is used to assist in positioning the assembled gear rotating shaft, the specific structure of the conveying assembly 1 is as follows:

[0053] See also Figure 1 The conveying assembly 1 includes a base 11 and a first electric slide rail 12 installed on the top of the base 11. The top of the first electric slide rail 12 is slidably connected to the second electric slide rail 13. The first electric slide rail 12 and the second electric slide rail 13 are arranged alternately. The top of the second electric slide rail 13 is slidably connected to the platform 14. The first electric slide rail 12 and the second electric slide rail 13 can be a stepper motor linear guide slide module, which is not specifically limited here. The second electric slide rail 13 is connected to the slide seat of the first electric slide rail 12. The first electric slide rail 12 can use the corresponding slide seat to drive the second electric slide rail 13 to move. The platform 14 is connected to the slide seat of the second electric slide rail 13. When the second electric slide rail 13 is running, the slide seat of the second electric slide rail 13 can drive the platform 14 to move synchronously.

[0054] See also Figure 1 , Figure 6 and Figure 7 The processing component 2 includes a lifting electric slide rail 21 installed on the top of the base 11 and a lifting platform 22 slidably connected to one side of the lifting electric slide rail 21. A driving mechanism 24 is arranged on one side of the lifting platform 22. The lifting electric slide rail 21 can be a stepper motor linear guide slide module, which is not specifically limited here. The lifting platform 22 is connected to the slide seat of the lifting electric slide rail 21. The lifting electric slide rail 21 can use the corresponding slide seat to drive the lifting platform 22 to slide in the vertical direction. A rotating cylinder 23 is installed on one side of the lifting platform 22. The output end of the rotating cylinder 23 is connected to the driving mechanism 24. When sliding, the lifting platform 22 can drive the rotating cylinder 23 and the driving mechanism 24 to move up and down synchronously. At the same time, the rotating cylinder 23 can drive the driving mechanism 24 to rotate, thereby adjusting the direction of the driving mechanism 24.

[0055] Specifically, when the gears need to be assembled, the staff first places the gear box housing on the platform 14, and then places the gears on the output end of the driving mechanism 24. The processing component 2 and the conveying component 1 are then moved in coordination to adjust the gear box housing and the gears to a suitable assembly angle. The gears are then assembled into the interior of the gear box, and the movement is repeated to load multiple gears into the interior of the gear box.

[0056] Embodiment 2: Currently, the method of automatic gear installation is mainly applicable to gear boxes with relatively spacious space, while for those gear boxes with relatively narrow space, manual installation has to be relied upon. If manual installation is adopted, the efficiency and operability of gear assembly will be greatly limited.

[0057] For this purpose, an assembly component 8 is provided at the output end of the driving mechanism 24 , and the assembly component 8 is used to grab the gear driving the rotating shaft that needs to be assembled, and assemble the gear driving the rotating shaft inside the gear box.

[0058] See also Figure 6-Figure 9 The assembly component 8 includes a ring body 84 that passes through the output end of the driving mechanism 24. A three-jaw chuck 83 is concentrically installed on the side wall of the output end of the driving mechanism 24 away from the ring body 84. A tube body 802 is arranged between the ring body 84 and the three-jaw chuck 83. The three-jaw chuck 83 is used to clamp the rotating shaft in the middle of the gear, so that the rotating shaft and the gear can maintain a coaxial state with the ring body 84 and the tube body 802. The tube body 802 is used to connect with the output end of the driving mechanism 24. The driving mechanism 24 is composed of a driving box and a servo motor, and the output end of the servo motor extends to the inside of the driving box, and the output end of the servo motor is connected to the tube body 802 through a belt transmission structure, so that the tube body 802 can be driven to rotate by the driving mechanism 24.

[0059] See also Figure 6-Figure 9 A mounting plate 88 is connected between the tube body 802 and the ring body 84. When the tube body 802 rotates, the ring body 84 uses the mounting plate 88 to maintain synchronous rotation with the tube body 802. Two conical blocks 85 are provided at one end of the ring body 84. The top and bottom of the mounting plate 88 are swingably connected with swing arms 89. The swing arms 89 are respectively hinged to the opposite end positions of the ring body 84 and the tube body 802, and the hinge points are connected with torsion springs, that is, one end of the torsion spring is connected to the swing arm 89, and the other end of the torsion spring is connected to the ring body 84 or the tube body 802. The two swing arms 89 are arranged corresponding to the two conical blocks 85, and the ends of the swing arms 89 are connected to the opposite ends. The conical block 85 should be connected, and a telescopic rod is installed on the side of the mounting plate 88 close to the conical block 85. The end of the telescopic rod passes through the mounting plate 88 and is connected to the guide rail 801. Two guide blocks are slidably connected to the side wall of the guide rail 801. Two swing arms 89 are arranged corresponding to the two guide blocks. One end of the swing arm 89 away from the conical block 85 is hinged to the end of the corresponding guide block. The telescopic rod is extended and retracted, thereby driving the guide rail 801 and the two guide blocks to move, causing the guide rail 801 and the two guide blocks to squeeze or pull the two swing arms 89. The swing arms 89 swing under the drive of squeezing or pulling, thereby driving the two conical blocks 85 to move.

[0060] See also Figure 8 The outer walls of the two conical blocks 85 are each provided with a slide groove 86, and a slider 87 is slidably connected inside the slide groove 86. The slider 87 can slide inside the corresponding slide groove 86 to adapt to the spacing of the gear teeth. Before assembling the gear, the staff first adjusts the spacing of the slider 87, and there is no need to adjust it again when the gear is continuously assembled.

[0061] Specifically, the gear transfer robot passes the first set of gears with rotating shafts through the ring body 84 and the inside of the tube body 802 , and the gears are located inside the tube body 802 , and the rotating shafts are clamped and limited by the three-jaw chuck 83 .

[0062] See also Figure 7 The assembly component 8 also includes an extrusion cylinder 81 installed on the side wall of the driving mechanism 24. The end of the piston rod of the extrusion cylinder 81 is connected to an extrusion rod 82. The extrusion rod 82 is coaxially arranged with the ring body 84. The extrusion cylinder 81 is used to drive the extrusion rod 82 to move. A groove is arranged at the end of the extrusion rod 82. The diameter of the groove is the same as the diameter of the rotating shaft in the gear, and an electromagnetic block is arranged inside the groove. When the gear needs to be assembled into the gear box, the extrusion rod 82 is used to displace the rotating shaft limited on the three-jaw chuck 83, that is, the rotating shaft is inserted into the groove, and the electromagnetic block is used to adsorb the rotating shaft. At the same time, the extrusion rod 82 squeezes the rotating shaft when moving, so that the rotating shaft and the gear move synchronously to the position of the gear box, thereby realizing the assembly of the gear.

[0063] See also Figure 1-Figure 3A fixing seat 4 is arranged on the top of the platform 14, and a positioning assembly 3 is installed on the top of the platform 14. The gear box is composed of a housing main body and two end cover parts. Both sides of the housing main body are connected. Before the gear is assembled, the positioning assembly 3 is first used to limit one side of the main body of the gear box. During the gear assembly process, the positioning assembly 3 is first used to limit the assembled gear. The specific structure of the positioning assembly 3 is as follows:

[0064] The positioning assembly 3 includes a positioning electric slide 31 installed on the top of the platform 14. The extension direction of the positioning electric slide 31 is the same as the extension direction of the first electric slide 12. The top of the positioning electric slide 31 is slidably connected with a positioning seat 32. A positioning cylinder 33 is horizontally installed on the top of the positioning seat 32. The extension direction of the piston rod of the positioning cylinder 33 is the same as the extension direction of the second electric slide 13. A vertical plate 34 is vertically installed at the end of the piston rod of the positioning cylinder 33. A positioning plate 35 is installed on one side of the vertical plate 34. The positioning electric slide 31 can be a stepper motor linear guide slide module, which is not specifically limited here. The positioning electric slide 31 is used to drive the positioning seat 32 and the positioning The cylinder 33, the vertical plate 34 and the positioning plate 35 move synchronously, so that the positioning plate 35 can be moved away from the side wall of the shell main part or approach the side wall of the shell main part. The positioning cylinder 33 is used to push the vertical plate 34 and the positioning plate 35 to move, so that the positioning plate 35 can be attached to the side wall of the shell main part or separated from the attached state of the side wall of the shell main part. A plurality of through holes are opened on one side of the positioning plate 35, and an aperture clamping mechanism 36 is installed on the side wall of the positioning plate 35 and at the corresponding position of each through hole. The aperture clamping mechanism 36 changes the size of the central circular aperture by the clutch of a plurality of overlapping arc-shaped metal blades, thereby realizing the clamping function.

[0065] Specifically, the first electric slide rail 12 and the second electric slide rail 13 cooperate to move, so that the main body of the shell and the end cover part move synchronously to the assembly position, and the lifting electric slide rail 21 drives the lifting platform 22 to move downward, and the rotating cylinder 23 drives the driving mechanism 24 to swing to a horizontal state, so that the first group of gears move to the side wall position of the main body of the shell, and then the positioning electric slide rail 31 drives the positioning seat 32, the positioning cylinder 33, the vertical plate 34 and the positioning plate 35 to approach the main body of the shell, and then the positioning cylinder 33 pushes the vertical plate 34 and the positioning plate 35 to move, so that the positioning plate 35 is in contact with one side of the main body of the shell. After the positioning plate 35 is in contact with the main body of the shell, the rotating shaft of the first group of gears is aligned with one of the through holes on the side wall of the positioning plate 35, and then the extrusion cylinder 81 pushes the extrusion rod 82 to move, and the extrusion rod 82 pushes the first group of rotating shafts and the gears to move at the same time, so that the first group of rotating shafts are inserted into the corresponding through holes, and the corresponding aperture clamping mechanism 36 clamps and fixes them.

[0066] Then the processing assembly 2 is reset, and the gear transfer manipulator places the second set of gears and clamps them through the three-jaw chuck 83. At this time, the two conical blocks 85 clamp the rotating shaft, and the spacing between the two sliders 87 is adjusted to the same position as the spacing of the gear teeth. Then the processing assembly 2 drives the second set of gears and the rotating shaft to approach the main body of the shell again. In this process, the driving mechanism 24 is first used to drive the ring body 84 and the tube body 802 to rotate slightly forward and backward. In this state, the two conical blocks 85 drive the second set of gears and the rotating shaft to rotate slightly forward and backward. The conical surfaces of the two conical blocks 85 first fit with the first set of gear teeth inside the main body of the shell, and then the two sliders 87 gradually align with the first set of gear teeth. After the alignment is completed, the driving mechanism 24 stops rotating, and the extrusion cylinder 81 pushes the extrusion rod 82 to move and clamp the rotating shaft of the second set of gears. The extrusion rod 82 pushes the second set of gears and the rotating shaft that remain axially stationary to move, and the second set of gears enters the main body of the shell, and the pre-alignment of the two sliders 87 is used to complete the meshing state with the first set of gears. This operation can realize the pre-alignment and meshing assembly of gears in a gearbox with a small space, that is, meet the purpose of automatic assembly of gears in a small space gearbox.

[0067] Embodiment 3, however, in order to achieve a stable position of the shaft and the gear during assembly, generally one side of the gear box will first be installed with an end cover, and when the gear is installed, the shaft will be inserted into the hole of the end cover to achieve the purpose of positioning. However, after the conical block 85 is provided to realize automated installation, the conical block 85 cannot be removed, that is, the conical block 85 and the end cover will interfere with each other.

[0068] For this purpose, see Figure 1-Figure 2 A first fixing assembly 6 and two sets of second fixing assemblies 7 are arranged on the top surface of the fixing seat 4. The first fixing assembly 6 and the two sets of second fixing assemblies 7 are used to fix the main part of the gearbox housing and the two end cover parts respectively. The specific structure of the first fixing assembly 6 is as follows:

[0069] See also Figure 2 and Figure 4Two sets of rails 5 are installed on the top of the fixed seat 4. The first fixing component 6 includes a connecting platform 61 installed on the top of the positioning component 3. The two sets of rails 5 are arranged through the connecting platform 61. A U-shaped frame 62 is installed on the top of the connecting platform 61. A lifting cylinder 63 is installed vertically upward inside the U-shaped frame 62. The piston rod of the lifting cylinder 63 passes through the top of the U-shaped frame 62 and is connected to a fixing plate 64. Both sides of the fixing plate 64 are provided with locking mechanisms 65 for fixing the gear box housing. The fixing plate 64 is used to place the main part of the gear box housing, and the locking mechanism 65 fixes the main part of the housing. The locking mechanism 65 is composed of a screw rod, a nut, and a clamping component. The staff manually rotates the screw rod, and the clamping component moves along the screw rod, thereby clamping or releasing the main part of the housing. The lifting cylinder 63 is used to push the fixing plate 64 and the main part of the housing up and down, thereby adjusting the height of the main part of the housing to meet the assembly conditions.

[0070] See also Figure 5 , two groups of second fixing components 7 are respectively arranged on both sides of the first fixing component 6, and the two groups of second fixing components 7 include a sliding table 71 slidably connected to the top of the track 5 and a bracket 72 installed on the top of the corresponding sliding table 71. A driving motor 73 is horizontally installed on one side of the bracket 72, and a connecting rod 74 is connected to the output end of the driving motor 73. A flip plate 75 for positioning the gear box housing is installed on the outer wall of the connecting rod 74. The flip plate 75 is used to position the end cover part of the gear box housing, and the connecting rod 74 is driven to rotate by the driving motor 73, so that the connecting rod 74 drives the flip plate 75 and the housing end cover part to swing, thereby adjusting the angle and state of the housing end cover part, and the sliding table 71 is used to drive the corresponding group of second fixing components 7 to slide on the track 5 as a whole, thereby adjusting the spacing between the housing end cover part and the housing main body part, which is convenient for the subsequent docking operation of the end cover part and the main body part.

[0071] Specifically, the main body and two end cover parts of the gear box housing are transferred by the housing transfer manipulator, the housing body is placed on the top of the fixed plate 64, the two locking mechanisms 65 fix the fixed plate 64, and the two end covers are fixed on the flip plates 75 respectively. Then, the driving motors 73 on the two sets of second fixing components 7 drive the corresponding connecting rods 74 to rotate, and the connecting rods 74 drive the corresponding flip plates 75 and end covers to swing to a horizontal state for standby use. Then, the gears are continuously assembled using the processing component 2 and the assembly component 8. When assembling the second set of gears, the two conical blocks 85 need to be first assembled with the first A group of gears are pre-aligned in the assembly movement direction. After the pre-alignment is completed, the telescopic rod contracts and drives the guide rail 801 and the two guide blocks to move, causing the guide rail 801 and the two guide blocks to squeeze the two swing arms 89. The swing arms 89 swing under the drive of squeezing, and then drive the two conical blocks 85 to move and separate, and the two conical blocks 85 move between the ring body 84 and the tube body 802. After that, the second group of gears continues to be pushed and moved by the squeezing rod 82 to mesh with the first group of gears for assembly. In this state, automatic assembly can be achieved, and the conical blocks 85 can be disassembled without interference with the end covers.

[0072] In order to ensure the assembly stability of the gears when the end covers are not installed, the positioning assembly 3 is used to stably clamp the assembled gears. After all the gears are assembled, the end covers are installed one by one, and when the shell body is in a through state, interference with the conical block 85 is further prevented.

[0073] Embodiment 4, a method for continuously assembling gears for a reducer, using the above-mentioned continuous assembly device for gears for a reducer, comprises the following steps:

[0074] S1. The main part and two end cover parts of the gear box housing are respectively placed on the first fixing component 6 and two groups of second fixing components 7 through the housing transfer robot, and then the two groups of second fixing components 7 respectively drive the corresponding end covers to swing to a horizontal state, and at the same time the first fixing component 6 drives the housing body to rise to a certain height. During this process, the gear transfer robot passes the first group of gears with rotating shafts through the interior of the ring body 84, and the rotating shafts are clamped by the three-jaw chuck 83.

[0075] The more specific steps of S1 are:

[0076] S11. The main body and two end cover parts of the gear box housing are transferred by the housing transfer robot. The housing body is placed on the top of the fixed plate 64. Two locking mechanisms 65 fix the fixed plate 64. The two end covers are respectively fixed on the flip plates 75. Then, the driving motors 73 on the two groups of second fixed components 7 drive the corresponding connecting rods 74 to rotate, and the connecting rods 74 drive the corresponding flip plates 75 and end covers to swing to a horizontal state for standby use.

[0077] S12. During this process, the gear transfer robot passes the first set of gears with rotating shafts through the ring body 84 and the inside of the tube body 802, and the gears are inside the tube body 802, and the rotating shafts are clamped by the three-jaw chuck 83.

[0078] S2. After the preparation work is completed, the conveying component 1 drives the main body of the shell and the end cover part to move synchronously to the assembly position, and the lifting electric slide rail 21 drives the lifting platform 22 to move downward, causing the gear to move to the side wall position of the main body of the shell, and then the positioning component 3 is fitted with one side of the main body of the shell, and the first group of gears and the rotating shaft are aligned with the positioning component 3 and the main body of the shell to complete the placement.

[0079] The more specific steps of S2 are:

[0080] S21. After the preparation work is completed, the first electric slide rail 12 and the second electric slide rail 13 move in coordination, so that the main part of the shell and the end cover part move synchronously to the assembly position, and the lifting electric slide rail 21 drives the lifting platform 22 to move downward, and the rotating cylinder 23 drives the driving mechanism 24 to swing to a horizontal state, so that the first set of gears moves to the side wall position of the main part of the shell.

[0081] S22, the positioning electric slide rail 31 then drives the positioning seat 32, the positioning cylinder 33, the vertical plate 34 and the positioning plate 35 to approach the main part of the shell, and then the positioning cylinder 33 pushes the vertical plate 34 and the positioning plate 35 to move, so that the positioning plate 35 fits with one side of the main part of the shell.

[0082] S23, after the positioning plate 35 is fitted with the main part of the shell, the rotating shaft of the first group of gears is aligned with one of the through holes on the side wall of the positioning plate 35, and then the extrusion cylinder 81 pushes the extrusion rod 82 to move, and the extrusion rod 82 pushes the first group of rotating shafts and the gears to move at the same time, causing the first group of rotating shafts to be inserted into the corresponding through holes, and the corresponding aperture clamping mechanism 36 clamps and fixes it.

[0083] S3. Then the processing component 2 is reset, and the gear transfer robot places the second group of gears and clamps them through the three-jaw chuck 83. At this time, the two conical blocks 85 clamp the rotating shaft, and the spacing between the two sliders 87 is adjusted to the same position as the spacing between the gear teeth. Then the processing component 2 drives the second group of gears and the rotating shaft to approach the main body of the shell again. In this process, the driving mechanism 24 is first used to drive the ring body 84 and the tube body 802 to rotate slightly forward and backward. The conical surfaces of the two conical blocks 85 first fit with the first group of gear teeth inside the main body of the shell, and then the two sliders 87 gradually align with the first group of gear teeth. After the alignment is completed, the driving mechanism 24 stops rotating, and the second group of gears enters the main body of the shell.

[0084] The more specific steps of S3 are:

[0085] S31. Then the processing component 2 is reset, and the gear transfer robot places the second group of gears and clamps them through the three-jaw chuck 83. At this time, the two conical blocks 85 clamp the rotating shaft, and the spacing between the two sliders 87 is adjusted to the same position as the spacing between the gear teeth. Then the processing component 2 drives the second group of gears and the rotating shaft to approach the main body of the shell again. In this process, the driving mechanism 24 is first used to drive the ring body 84 and the tube body 802 to rotate slightly forward and backward. The conical surfaces of the two conical blocks 85 first fit with the first group of gear teeth inside the main body of the shell, and then the two sliders 87 gradually align with the first group of gear teeth. After the alignment is completed, the driving mechanism 24 stops rotating, and the extrusion cylinder 81 pushes the extrusion rod 82 to move and clamp the rotating shaft of the second group of gears. The extrusion rod 82 pushes the second group of gears and the rotating shaft that remain axially stationary to move, and the second group of gears enters the main body of the shell.

[0086] S4, then the two conical blocks 85 are separated, and the second set of gears are assembled with the first set of gears, and the third set of gears is assembled through the steps of S3 in a reciprocating manner.

[0087] The more specific steps of S4 are:

[0088] S41, the telescopic rod contracts and drives the guide rail 801 and the two guide blocks to move, causing the guide rail 801 and the two guide blocks to squeeze the two swing arms 89. The swing arms 89 swing under the drive of squeezing, and then drive the two conical blocks 85 to move and separate, and the two conical blocks 85 move out from between the ring body 84 and the tube body 802. After that, the second set of gears continues to be pushed and moved by the squeezing rod 82 to mesh with the first set of gears for assembly.

[0089] S42, the processing assembly 2 is reset, the gear transfer robot places the third set of gears again and clamps them through the three-jaw chuck 83, and completes the next alignment assembly through the step of S3.

[0090] S5. After the gear assembly is completed, one group of second fixing components 7 drives the end cover to swing to a vertical state and approaches the direction of the first fixing component 6, thereby completing the assembly of one end cover and the shell body. Subsequently, the positioning component 3 is separated from the shell body, and the other end cover is also swung to a vertical state and assembled with the shell body.

[0091] The more specific steps of S5 are:

[0092] S51. After the gear assembly is completed, the driving motor 73 in one group of the second fixed components 7 drives the connecting rod 74 to rotate, causing the corresponding flip plate 75 and the end cover to swing to a vertical state and approach the direction of the first fixed component 6, thereby completing the assembly of one end cover and the shell body. Subsequently, the aperture clamping mechanism 36 releases the corresponding rotating shaft, and then uses the positioning electric slide rail 31 and the positioning cylinder 33 to drive the positioning plate 35 away from the shell body, and then the other end cover also swings to a vertical state and completes the assembly with the shell body.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
