Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing equipment technology, and in particular to a rapid assembly device for a three-phase motor housing. Background Technology

[0002] Three-phase motors are widely used power equipment in industrial production. In the motor manufacturing process, the splicing of the motor housing and the top cover is an important assembly step. Currently, the splicing of three-phase motor housings is mostly done manually or semi-automatically. Operators first manually place the housing body on the workbench, then manually remove the top cover body to close it, and finally use electric screwdrivers and manual tools to tighten the fixing screws one by one. This highly manual operation method not only leads to low assembly efficiency, but also makes it difficult to ensure the consistency of screw tightening torque and splicing quality in mass production.

[0003] To improve efficiency, some semi-automated workstations, independent top-covering workstations, and automatic locking workstations have emerged in the industry. However, these workstations have limited functions and are scattered. After the top cover is completed, the workpiece still needs to be picked up and moved to the lower locking workstation manually. After locking, it still needs to be manually moved to the finished product area for collection.

[0004] This production model, which separates the capping, locking, and collection processes, results in a disjointed assembly process with a very low level of automation. The transfer of workpieces between different workstations not only wastes a lot of time but also increases the labor intensity of workers, failing to achieve truly rapid and continuous operation and severely restricting the overall production efficiency of motor housings.

[0005] Therefore, this utility model proposes a rapid assembly device for three-phase motor housings to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems of dispersed workstations, low automation, reliance on manual transfer of workpieces between different processes, and low overall splicing efficiency in existing rapid splicing equipment for three-phase motor housings, this utility model aims to provide a rapidly splicing equipment for three-phase motor housings with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a rapid assembly device for a three-phase motor housing, comprising: a base frame, an assembly platform disposed on the top of the base frame, a top cover placement platform fixed to the rear side of the top of the assembly platform, and a fixing column fixed to the right side of the top of the assembly platform. A drive motor is fixed inside the assembly platform. The drive motor is connected to the turntable via a belt, a rotating shaft, and a transmission gearbox. The turntable is mounted on the assembly platform and is used to support the rotation of the outer casing. Furthermore, the top cover placement platform is positioned above the rotation path of the turntable, and a front-push cylinder is fixed to the rear side of the top cover placement platform.

[0008] The top of the fixed column is fixed with a positioning cylinder, which in turn fixes a pressing cylinder. The pressing cylinder drives the installation drill, which is also positioned above the rotation path of the turntable.

[0009] It also includes a fixed platform and a slide. The fixed platform is fixed to the top of the variable box and has a drop hole. The slide is located at the bottom of the drop hole and is used to collect the assembled outer shell that falls when the turntable rotates to the position of the drop hole.

[0010] Preferably, the bottom of the base frame is fixed with feet and casters.

[0011] Preferably, the output end of the drive motor is rotatably connected to the belt, and the other end of the belt is rotatably connected to the rotating shaft.

[0012] Preferably, the rotating shaft drives the turntable to rotate via the variable gearbox.

[0013] Preferably, the output end of the positioning cylinder is fixed to the pressing cylinder.

[0014] Preferably, the top cover placement platform is used to accommodate the top cover body, and the forward push cylinder is used to push the top cover body to the front side of the top cover placement platform so that it can fall on top of the outer shell body.

[0015] Preferably, the fixed platform is stationary, and the slide is fixed to the bottom of the drop hole opened on the fixed platform.

[0016] Preferably, the positioning cylinder is used to determine the installation position, and the pressing cylinder is used to drive the mounting drill to fix the screw.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of dispersed workstations, reliance on manual handling and step-by-step operation, and difficulty in achieving continuous automated operation in the prior art by setting up a turntable driven by a drive motor and arranging a top cover placement platform for automatic cover installation, an installation drill for automatic locking, and a slide for automatic collection of finished products in sequence around the rotation path of the turntable. It achieves the integration of cover installation, screw fastening and finished product collection into one unit, realizing rapid assembly line splicing.

[0018] 2. This utility model uses a front-push cylinder to automatically lower the top cover onto the outer shell, followed by a combination of a positioning cylinder and a pressing cylinder to drive the installation drill for automatic locking. This solves the problems of manual operation, slow speed, inaccurate positioning, and high labor intensity in the existing technology for the top cover and locking process. It achieves a high degree of automation, tight action connection, and precise and reliable splicing, effectively ensuring the consistency of product quality. Attached Figure Description

[0032] As another preferred implementation method, for the purpose of automatic collection of finished products, please refer to... Figure 1 and Figure 3The fixed platform 10 is fixed on the top of the variable box 8 and remains stationary. The drop hole opened on the fixed platform 10 corresponds to the unloading station on the rotation path of the turntable 9. The slide 11 is fixed at the bottom of the drop hole opened on the fixed platform 10 and is used to guide the assembled shell to slide out of the equipment.

[0033] Working principle: During equipment initialization, the operator places the outer shell body 18 to be assembled onto the turntable 9. The turntable 9 is mounted on the assembly table 2 and is used to support and rotate the outer shell body 18. When the operator starts the equipment, the drive motor 5 fixed inside the assembly table 2 starts to work. The output end of the drive motor 5 is rotatably connected to the belt 6. The belt 6 is wrapped around the output shaft and the rotating shaft 7 of the drive motor 5. The other end of the belt 6 is rotatably connected to the rotating shaft 7. The rotation of the rotating shaft 7 transmits power to the variable box 8. The variable box 8 is fixed inside the assembly table 2. The output end of the variable box 8 extends upward and is fixedly connected to the turntable 9. The variable box 8 acts as a deceleration and steering mechanism to drive the turntable 9 to rotate according to the preset program. Turntable 9 carries the outer shell body 18 and rotates along a preset rotation path. When the outer shell body 18 moves directly below the top cover placement platform 16, the turntable 9 stops rotating. The top cover placement platform 16 is fixed to the top rear side of the assembly platform 2. The outlet of the top cover placement platform 16 is located above the rotation path of the turntable 9. At this time, the front push cylinder 17 fixed to the rear side of the top cover placement platform 16 is activated. The push rod of the front push cylinder 17 pushes the top cover body 19. The top cover body 19 was previously housed inside the top cover placement platform 16. The front push cylinder 17 pushes the top cover body 19 to move along the guide rail inside the top cover placement platform 16 to the outlet on the front side of the top cover placement platform 16. After the top cover body 19 is separated from the top cover placement platform 16, it falls on the top of the outer shell body 18 on the turntable 9 directly below under the action of gravity, completing the automatic cover-up action. After the top cover is completed, the drive motor 5 starts again, driving the turntable 9 to continue rotating via the belt 6, the rotating shaft 7 and the change box 8. This transports the outer shell body 18, which has been covered with the top cover body 19, to the area directly below the mounting drill 15. This is the screw tightening station. The mounting drill 15 is also positioned above the rotation path of the turntable 9. The mounting drill 15 is connected to the positioning cylinder 13 via the pressing cylinder 14. The positioning cylinder 13 is fixed to the top of the fixing column 12, which is fixed to the top right side of the assembly table 2. When the workpiece is in place, the turntable 9 pauses again. The positioning cylinder 13 starts first. The positioning cylinder 13 is used to accurately determine the installation position in the horizontal direction, ensuring that the mounting drill 15 is aligned with the screw hole. After the positioning cylinder 13 is positioned, the pressing cylinder 14, which is fixed to the output end of the positioning cylinder 13, starts. The pressing cylinder 14 drives the mounting drill 15 to move vertically downward. The mounting drill 15 starts to rotate and tightens the screw, thereby firmly fixing and splicing the outer shell body 18 and the top cover body 19 together, completing the splicing of the outer shell. After the screws are tightened, the drive motor 5 starts for the third time, driving the turntable 9 to continue rotating via the belt 6, the rotating shaft 7 and the variable box 8, transporting the assembled shell to the unloading station. The unloading station corresponds to the drop hole opened in the fixed platform 10. The fixed platform 10 is fixed on the top of the variable box 8 and remains stationary while the turntable 9 rotates. When the assembled shell rotates to directly above the drop hole, because the fixed platform 10 is stationary and the drop hole is opened on the top, the assembled shell will fall off the turntable 9 under the action of gravity, pass through the drop hole, and fall onto the slide 11 at the bottom of the drop hole. The slide 11 is fixed at the bottom of the drop hole opened in the fixed platform 10. The assembled shell slides out of the equipment along the slide 11, completing the automatic collection. When it is necessary to move and fix the equipment, the equipment can be pushed by the casters 4 at the bottom of the base frame 1. After reaching the designated position, the feet 3 fixed at the bottom of the base frame 1 can be adjusted so that the feet 3 extend and contact the ground, and the casters 4 can be lifted to fix the entire equipment. The rotation of the turntable 9 drives the outer shell 18 to automatically pass through the top cover station, the locking station and the unloading station in sequence, realizing the continuous automated splicing of the three-phase motor shell, replacing the traditional manual and scattered operation, and solving the problems of low splicing efficiency and slow speed.
