Description

Technical Field

[0001] This utility model relates to motor assembly equipment, specifically a motor assembly line. Background Technology

[0002] Currently, ordinary permanent magnet motors typically consist of components such as a stator, rotor, front cover, rear cover, fan, and rear cover. During assembly, the front end is usually fixed to the stator first, then the rotor is installed, followed by the rear cover. The coaxiality of the rotor and stator is particularly important for the reliability and stability of the motor during assembly. Finally, the fan and rear cover are assembled. Currently, the installation steps involve installing the rear cover and rotor separately, which can easily cause deviations in the coaxiality of the rotor and stator, increasing the assembly difficulty. In addition, after the existing assembly line is completed, it is necessary to conduct a power-on test in the next process to ensure that the product can operate normally before it is considered to have passed the test. Utility Model Content

[0003] The purpose of this utility model is to provide a motor assembly line that combines the assembly of the rotor and the rear end cover. At the same time, an electrical testing station is set up on the assembly line, and the motor assembly and electrical testing are completed simultaneously on the assembly line, ensuring assembly quality and improving production efficiency.

[0004] To achieve the above objectives, the following technical solution is adopted:

[0005] A motor assembly line includes a base and an upper frame. The upper frame is mounted on the base. Two parallel conveyor channels are arranged along the length of the base on the top of the base. The two conveyor channels are connected on both sides by a transmission device. The upper frame is located between the two parallel conveyor channels, isolating them. The line is characterized in that: several conveyor positioning plates are placed within the conveyor channels, each with a clearance hole at its center. Stator and front end cover assembly parts are placed on the conveyor positioning plates, with the stator axially coaxial with the clearance hole. Several workstations are arranged on the conveyor channels, each with a blocking device. At least one workstation has an integrated rotor and rear end cover assembly device. An electrical testing chamber is located on one side of the integrated rotor and rear end cover assembly device, and the conveyor channel passes through the electrical testing chamber.

[0006] The power-on testing chamber is an enclosed space, and a lifting door is installed at the position of the power-on testing chamber corresponding to the transmission path of the transmission channel.

[0007] The rotor and rear end cover integrated assembly device includes a base, with an overhang located directly above the conveying channel on the upper part of the base. A pressing mechanism is provided at the bottom of the overhang. The pressing mechanism includes a pressing seat, on which a guide rod and a screw are provided. The guide rod cooperates with a guide sleeve on the overhang, and the screw is threadedly engaged with a nut sleeve on the overhang. The nut sleeve is pivotally connected to the pivot seat of the overhang and is driven by a lifting motor.

[0008] The press-fitting base includes a clamping base and an end cap positioning sleeve. The end cap positioning sleeve is fixed to the bottom of the clamping base. A spindle clamp is provided on the clamping base. The spindle clamp has a clamping opening, which is connected to and coaxially arranged with the center hole of the end cap positioning sleeve.

[0009] This invention integrates the rotor and rear end cover into a single assembly using a press-fitting mechanism. Simultaneous assembly of the rotor and rear end cover ensures better concentricity between the rotor and stator. Furthermore, this invention adds an electrical testing chamber to the production line. Once the stator and rotor are assembled, they immediately enter the electrical testing chamber for testing. Any problems found are promptly returned to the production line, saving time and improving efficiency. Attached Figure Description

[0016] like Figure 1-6As shown, a motor assembly line includes a base 1 and an upper frame 2. The upper frame 2 is mounted on the base 1. Two parallel conveyor channels 3 are arranged along the length of the base 1 on its top. The two sides of the two conveyor channels 3 are connected by a transmission device 4. The upper frame 2 is located between the two parallel conveyor channels 3, isolating them. Several conveyor positioning plates 5 are placed inside the conveyor channels 3. The conveyor positioning plates 5 have clearance holes 51 in their centers. The stator 61 and the front end cover 62 are placed on the conveyor positioning plates 5. The stator 61 is axially coaxial with the clearance holes 51. Several workstations are arranged on the conveyor channels 3. Each workstation is also equipped with a blocking device 50. At least one workstation is equipped with a pressing mechanism 7 for the integrated assembly of the rotor 63 and the rear end cover 64. The pressing device 7 includes a base 71, with an extension 72 located directly above the conveying channel on the upper part of the base 71. A pressing mechanism is provided at the bottom of the extension 72. The pressing mechanism includes a pressing seat 9, on which a guide rod 73 and a screw 74 are provided. The guide rod 73 cooperates with a guide sleeve 75 on the extension 72, and the screw 74 is threadedly engaged with a nut sleeve 76 on the extension 72. The nut sleeve 76 is pivotally connected to the pivot seat of the extension 72 and is driven by a lifting motor 77. The pressing seat 9 includes a clamping seat 91 and an end cap positioning sleeve 92. The end cap positioning sleeve 92 is fixed to the bottom of the clamping seat 91. A main shaft clamp 93 is provided on the clamping seat 91. The main shaft clamp 93 has a clamping port 94, which communicates with and is coaxially arranged with the center hole 95 of the end cap positioning sleeve 92.

[0017] An electrical testing chamber 8 is also provided on one side of the pressing mechanism 7, and the conveying channel 3 passes through the electrical testing chamber 8; the electrical testing chamber 8 is a closed space, and a lifting door 81 is provided at the position of the electrical testing chamber 8 corresponding to the conveying path of the conveying channel 3.

[0018] This invention first assembles the stator 61 and the front cover 62, then places the assembly onto the conveyor positioning plate 5. The width of the conveyor positioning plate 5 matches the conveyor channel 3 to ensure that rotation does not occur during the conveying process. A blocking device 50 is installed at each station of the conveyor channel 3. The blocking device 50 can be raised or lowered via a control button. When the blocking device 50 is raised, it blocks the conveyor positioning plate 5, thus positioning it. At this time, the clearance hole 51 is aligned axially with the pressing mechanism 7 and the pressing base 9. The worker then aligns the lower end of the rotor 63's shaft with the center hole of the front cover 62, then places the rear cover 64 onto the upper end of the shaft, and finally starts the pressing mechanism 7. The clamping seat 91 at the bottom of the mechanism 7 clamps the shaft of the rotor 63 to ensure that the shaft is coaxial with the front cover 62. The driving pressing seat 9 of the pressing mechanism 7 presses down to make the rotor 63 accurately enter the stator 61 and remain coaxial with the stator 61 and the front cover 62. After the rotor 63 is in place, the clamping seat 91 releases the clamping force. At this time, the pressing seat 9 continues to press down so that the end cover positioning sleeve 92 cooperates with the rear cover 64. Since the bottom of the end cover positioning sleeve 92 is provided with a positioning groove that matches the shape of the rear cover 64, the rear cover 64 is accurately positioned. When the rear cover 64 is pressed down to the positioning upper port, the pressing mechanism 7 resets. Then, the worker uses a special tool to fix the rear cover 64 to the stator 61 and completes the assembly of the rotor and the rear cover.

[0019] After the rear end cover 64 and stator 61 are assembled, the lifting door 81 of the power-on test chamber 8 is opened, and the assembled motor enters the power-on test chamber 8 through the conveyor channel 3. After passing the power-on test requirements in the power-on test chamber 8, the fan and rear cover are assembled in the subsequent workstation, and then the subsequent quality inspection and packaging are carried out. If the power-on test fails, the motor is immediately returned to the production line for repair.

[0020] This invention integrates the rotor and the rear end cover into a single assembly. Simultaneous assembly of the rotor and the rear end cover better ensures the concentricity of the rotor and stator, improving assembly quality and efficiency. In addition, this invention places the power-on testing chamber on the production line. After the stator and rotor are assembled, they immediately enter the power-on testing chamber for testing. If any problems are found, they are promptly returned to the production line, saving processes and further improving efficiency.
