Description

Technical Field

[0001] This utility model belongs to the field of motor assembly technology, and specifically relates to a motor assembly mechanism. Background Technology

[0002] Motor assembly is the process of precisely combining motor stator, rotor, housing, bearings and other components into a complete motor according to design requirements and process specifications. It requires operations such as positioning, pressing and fixing to ensure the positional accuracy and fit of each component. After debugging and testing, the motor can realize functions such as electromagnetic induction rotation and output of specified torque. It includes manual or automated assembly methods and directly affects the motor performance, reliability and production efficiency. It is a key link in the transformation of parts into finished products.

[0003] However, during motor assembly, various components such as stator, rotor, and housing need to be precisely assembled. This requires reliable fixing of the motor housing. However, traditional fixing methods have obvious limitations. They cannot easily adjust the height and angle of the motor housing according to the assembly process requirements. This results in frequent manual handling or the use of additional tooling to adjust the posture during operations such as press-fitting bearings and stator positioning. This not only increases assembly time but may also affect the positioning accuracy of components due to repeated displacement, making it difficult to meet the requirements of automated production lines for efficiency and flexibility.

[0004] To address the aforementioned problems, this application proposes a motor assembly mechanism. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figure 1-7 The present invention provides the following technical solution: a motor assembly mechanism, including a base plate 1, a collar 2 fixedly connected to the upper surface of the base plate 1, a rotating ring 3 rotatably connected inside the collar 2, a controller 4 fixedly connected to the front of the base plate 1, a first brake motor 8 arranged below the base plate 1, the power output end of the first brake motor 8 passing through the base plate 1 and the collar 2 in sequence and fixedly connected to the bottom surface of the rotating ring 3, two slot frames 10 arranged above the rotating ring 3, a sliding frame 11 slidably connected inside each slot frame 10, a first electric push rod 12 fixedly connected to the inner bottom wall of each slot frame 10, and the telescopic end of each first electric push rod 12 fixedly connected to the bottom surface of the sliding frame 11;

[0028] Each sliding frame 11 has a rotating sleeve 17 fixedly connected to its inner wall, a second electric push rod 13 fixedly connected to the inner wall of the inner tube of each rotating sleeve 17, a toothed ring 14 fixedly connected to the outer surface of the inner tube of each rotating sleeve 17, a second brake motor 16 set above each sliding frame 11, a gear 15 fixedly connected to the power output end of each second brake motor 16, each gear 15 meshing with the toothed ring 14, a pressure sensor 21 set at the telescopic end of each second electric push rod 13, and a clamping plate 22 fixedly connected to the sensing end of each pressure sensor 21.

[0029] In this embodiment, the controller 4 adopts a programmable logic controller (PLC), which is a digital computing electronic system designed specifically for industrial environments. It stores instructions through a programmable memory and can control various machines and production processes through digital or analog input / output interfaces. Meanwhile, the first brake motor 8 and the second brake motor 16 are both drive motors with integrated braking devices, consisting of a motor body and an electromagnetic brake mechanism. Its core feature is that when the motor is powered off, the brake device can act quickly, stopping the motor shaft immediately and keeping it stationary through mechanical braking, effectively preventing the load from being displaced due to gravity or inertia. In addition, the pressure sensor 21 is a device that can convert physical pressure signals into measurable electrical signals.

[0030] Specifically, the bottom surface of the base plate 1 is fixedly connected to two sets of support frames 5, with two support frames 5 in each set. Each support frame 5 has two fixing pins 6 inside. In this embodiment, the two sets of support frames 5 form a stable support for the structure, ensuring that the base plate 1 and the upper components remain horizontal and stable during assembly. The fixing pins 6 can pass through the preset mounting holes of the support frame 5 and the ground or workbench, so as to achieve a firm fixation of the entire mechanism and avoid the positioning accuracy being affected by the shaking of the equipment during the assembly process.

[0031] Specifically, a connecting seat 7 is fixedly connected to the left side of the first brake motor 8. The upper surface of the connecting seat 7 is fixedly connected to the bottom surface of the base plate 1. In this embodiment, the first brake motor 8 is rigidly connected to the base plate 1 through the connecting seat 7, which not only ensures the stability of the motor during operation, but also ensures that the motor output shaft is precisely aligned with the mounting holes of the base plate 1 and the collar 2 through the structural design of the connecting seat 7, thus ensuring the coaxiality of the power transmission and reducing vibration and noise during operation.

[0032] Specifically, each slot frame 10 has a fixed plate 9 fixedly connected to its bottom surface, and the bottom surface of each fixed plate 9 is fixedly connected to the upper surface of the rotating ring 3. In this embodiment, the fixed plate 9 increases the connection area between the slot frame 10 and the rotating ring 3, improves the connection strength, and makes the slot frame 10 less prone to deformation or loosening when bearing the weight of the sliding frame 11 and the upper components, thus ensuring the stability of the lifting and adjustment process.

[0033] Specifically, each second brake motor 16 has a support base 18 fixedly connected to its bottom surface, and the bottom surface of each support base 18 is fixedly connected to the upper surface of the sliding frame 11. In this embodiment, the support base 18 provides stable support for the second brake motor 16, while ensuring that the gear 15 on the motor output shaft and the gear ring 14 on the outer surface of the rotating sleeve 17 maintain a precise meshing state, ensuring power transmission efficiency and avoiding excessive meshing clearance or tooth breakage of the gear 15 due to unstable motor installation.

[0034] Specifically, each of the telescopic ends of the second electric push rod 13 is fixedly connected to a support ring 19. The sides of the two support rings 19 that are close to each other are fixedly connected to the sides of the two pressure sensors 21 that are far from each other. In this embodiment, the support rings 19 achieve a rigid connection between the second electric push rod 13 and the pressure sensor 21, which not only ensures the stable transmission of the thrust, but also provides an installation reference for the pressure sensor 21, ensuring that it can accurately monitor the reaction force on the clamping plate 22.

[0035] Specifically, two sets of telescopic rods 20 are fixedly connected to the sides of the two support rings 19 that are close to each other. The telescopic ends of the two sets of telescopic rods 20 are fixedly connected to the sides of the two clamping plates 22 that are far from each other. In this embodiment, the telescopic rods 20 form auxiliary support for the clamping plates 22. When the second electric push rod 13 drives the clamping plates 22 to move, it restricts them to move only in the horizontal direction to avoid tilting due to uneven force and ensure that the contact surface between the clamping plates 22 and the motor housing remains parallel.

[0036] Specifically, protective pads 23 are fixedly connected to the sides of the two clamping plates 22 that are close to each other. Each protective pad 23 is made of rubber. In this embodiment, the rubber protective pads 23 directly contact the motor housing. The elasticity of the rubber buffers the clamping force, avoiding the rigid collision between the clamping plates 22 and the housing, which could cause scratches or indentations. At the same time, the high coefficient of friction of the rubber can enhance the clamping stability and prevent the housing from sliding during the adjustment process.

[0037] The working principle and usage process of this utility model are as follows: In use, the mechanism is first fixed to the workbench via the support frame 5 and the fixed pin 6 on the bottom surface of the base plate 1, ensuring the base plate 1 is horizontal and stable. Then, the power supply to the controller 4 and each power component is connected. The adjustment parameters for the motor housing are preset on the controller 4's operating interface, including horizontal rotation angle, lifting height, tilt range, and clamping force threshold. The controller 4 automatically calls the corresponding parameter group according to the preset program to adapt to different models of motor housings. When the motor needs to be assembled, the operator places the housing between the two clamping plates 22 and activates the second electric push rod 13 via the controller 4. The second electric push rod 13 pushes the clamping plate 22 to move horizontally through the support ring 19, and the rubber protective pad 23 contacts the housing surface. At this time, the pressure sensor 21 monitors the clamping force in real time. When the value reaches the preset threshold, the controller 4 automatically controls the second electric push rod 13 to stop, completing the housing fixation. If the horizontal angle of the housing needs to be adjusted, the controller 4 drives the first brake motor 8 to operate. The motor shaft passes through the base plate 1 and the collar 2, driving the rotating ring 3 to rotate within the collar 2, thereby causing the upper slot frame 10 and the sliding frame to... The 11 and clamping components rotate synchronously to achieve radial adjustment. If height adjustment is required, the first electric push rod 12 extends and retracts to push the sliding frame 11 up and down within the slot frame 10, precisely controlling the vertical position of the outer shell. If tilt adjustment is required, the second brake motor 16 starts, and its gear 15 meshes with the gear ring 14 outside the rotating sleeve 17, driving the rotating sleeve 17 to rotate and tilt the outer shell. When switching assembly processes, the controller 4 links each component according to preset logic. For example, when switching from bearing press fitting to stator positioning, the first brake motor 8 first rotates the outer shell to align with the work position, then the first electric push rod 12 adjusts the height, and finally the second brake motor 16 tilts the outer shell to align the interface. When all assembly processes are completed, the motor is powered off, the electromagnetic brake immediately brakes and locks the position, and at the same time, the controller 4 controls the second electric push rod 13 to retract and release the clamp, and the mechanism resets to wait for the next workpiece. Throughout the process, the pressure sensor 21 continuously feeds back clamping force data. If there is an abnormality, an alarm is triggered to stop the machine, ensuring equipment safety. This mechanism, through multi-dimensional automatic adjustment, greatly reduces manual intervention, improves assembly efficiency and positioning accuracy, and is suitable for the needs of automated production lines.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
