Description

Technical Field

[0001] This invention relates to the field of motor stator and rotor fitting equipment, and particularly to an online new energy motor stator and rotor fitting equipment and fitting method. Background Technology

[0002] With the rapid development of the new energy industry, large and medium-sized new energy motors are increasingly widely used in industrial production, transportation and other fields. Since the safety and reliability of large and medium-sized motors directly affect the stable operation of the entire production system, extremely high requirements are required for the overall quality of large and medium-sized motors. This leads to more stringent standards for the stator and rotor assembly process in the motor assembly stage: not only must the assembly accuracy of the stator and rotor be guaranteed to avoid problems such as stator and rotor scratching and eccentricity, but production efficiency must also be improved to meet the needs of the large-scale market.

[0003] Therefore, in the existing technology, automatic stator and rotor assembly machines are gradually replacing traditional manual operation. However, the existing automatic assembly equipment still has obvious shortcomings: on the one hand, some equipment relies on manual assistance for loading and unloading or moving heavy motor housings and rotors, which is labor-intensive and has low operating efficiency, making it difficult to adapt to the weight requirements of large and medium-sized motors; on the other hand, the centering and fitting mechanism of the existing assembly equipment is prone to positioning deviations and tilting problems during the rotor assembly process, which in turn affects the coaxiality of the stator and rotor fitting and reduces the product yield. Therefore, it is necessary to improve the existing automatic stator and rotor assembly equipment to improve the assembly accuracy and increase the operating efficiency. Summary of the Invention

[0015] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an online new energy motor stator-rotor fitting method, using an online new energy motor stator-rotor fitting device as described in any of the above technical solutions, comprising: Step 1: The chain conveyor line sequentially transports the tray assembly carrying the rotor and stator housing to the handling station.

Step 4: The stator and rotor conveying assembly moves the assembled motor into the material box assembly. Then, the lifting assembly drives the material tray assembly to descend, and the chain conveyor outputs the material tray assembly carrying the assembled motor.

[0016] In summary, the present invention has the following beneficial effects: 1. A chain conveyor line for conveying the tray assembly is installed on the base, and a lifting and positioning component is installed on the chain conveyor line. Simultaneously, a stator-rotor transfer component and a stator-rotor handling component are respectively installed on the base to clamp and convey the stator housing and rotor from the tray assembly to the stator-rotor transfer component. The tray assembly carrying the rotor and stator housing is sequentially conveyed to the handling station via the chain conveyor line. The lifting and positioning component sequentially lifts the tray assembly carrying the rotor and stator housing. Subsequently, the stator-rotor handling component sequentially transports the rotor and stator housing from the tray assembly to the stator-rotor transfer component. The stator and rotor are positioned on the transfer assembly, and finally, the stator housing and rotor are assembled by the cooperation of the rotor synchronous pressing assembly and the stator and rotor transfer assembly. After the motor is assembled, the stator and rotor transport assembly transports the assembled motor to the material box assembly. Then, the lifting assembly drives the material tray assembly to descend, and the chain conveyor outputs the material tray assembly carrying the assembled motor, thus completing the automatic mating assembly of the motor stator and rotor. There is no need to rely on manual assistance for loading and unloading or carrying heavy motor housings and rotors, which greatly reduces labor intensity and improves the efficiency of motor stator and rotor mating assembly. 2. The rotor synchronous support assembly is vertically connected to the base via a screw-based lifting assembly. It consists of a support rod that abuts against the bottom of the rotor to lift it upwards. A lower pressure seat is mounted on the lower pressure seat, and several positioning pins with circumferentially fixed positioning holes are also present on the lower pressure seat. A clamping assembly is symmetrically fixed to the base to engage the rotor after it rises to the installation position. During the rotor lifting and assembly process, the support rod and the lower pressure seat synchronously press against the rotor from its upper and lower ends, respectively. The positioning pins on the lower pressure seat insert into the rotor mounting holes, further confining the rotor. The circumferential positioning ensures the stability of the rotor posture during the fitting process, preventing the rotor from tilting during assembly and guaranteeing the coaxiality of the rotor and stator housing during fitting. Simultaneously, an elastic pressure measuring component is installed between the telescopic end of the lowering cylinder and the lowering seat to monitor the lowering pressure. The pressure sensor in the elastic pressure measuring component monitors the fitting pressure in real time, and a buffer spring compensates for minor coaxiality deviations during fitting, preventing deformation of the stator and rotor walls due to excessive pressure or insecure fitting due to insufficient pressure, thus ensuring the accuracy of the motor stator and rotor fitting process.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: refer to Figure 1An online stator-rotor fitting device for new energy motors includes a base 1 and a chain conveyor 2 fixedly connected to the base 1 for conveying a tray assembly 7 carrying a stator housing or rotor. A lifting and positioning component 3 is fixedly connected to the chain conveyor 2 for lifting the tray assembly 7 for positioning. When the tray assembly 7 carrying the stator housing or rotor is conveyed to the handling and loading station via the chain conveyor 2, the lifting and positioning component 3 lifts the tray assembly 7 so that it detaches from the chain conveyor 2. When unloading is required, the lifting and positioning component 3 lowers the tray assembly 7, allowing it to be conveyed and unloaded along with the chain conveyor 2. A stator-rotor transfer component 4 for transferring the stator housing and rotor are fixedly connected to the base 1, as are a stator-rotor handling component 5 for clamping and conveying the stator housing and rotor from the tray assembly 7 to the stator-rotor transfer component 4. The stator and rotor transfer assembly 4 can simultaneously support the stator housing and the rotor, and can transfer the stator and rotor to the fitting station. At the fitting station of the base 1, there is also a rotor synchronous pressing assembly 6 for synchronously pressing the rotor to lift the rotor a second time, thereby realizing the stator and rotor. When fitting assembly is required, the stator and rotor transfer assembly 4 first moves the rotor to the fitting station, and then the rotor synchronous pressing assembly 6 drives the rotor to rise to a set height and stops. The set height needs to ensure that the stator housing can be moved to the underside of the rotor through the stator and rotor transfer assembly 4 and that the gap between the bottom of the rotor and the top of the stator housing is as small as possible. Then, the stator and rotor transfer assembly 4 transfers the stator housing to the bottom of the rotor located at the fitting station and makes the axis of the stator housing coincide with that of the rotor. Then, the rotor synchronous pressing assembly 6 drives the rotor to descend, thereby positioning and fitting the rotor into the stator housing to complete the assembly.

A center positioning seat 74 for positioning the center of the stator housing or rotor and a side wall positioning seat 75 for positioning the outer shaft wall of the center of the stator housing or rotor are fixedly connected to the quick-release mounting seat 73. Several support blocks 76 for supporting and positioning the bottom of the stator housing or rotor are evenly fixedly connected to the quick-release mounting seat 73 around the center positioning seat 74. The center positioning seat 74 and the side wall positioning seats 75 cooperate to achieve the positioning of the stator housing or rotor, and the support blocks 76 support the stator housing or rotor to maintain stability. Simultaneously, rotating the quick-release knob 72 allows for quick replacement of the quick-release mounting seat 73 to adapt to the feeding requirements of stator housings and rotors of different specifications. Symmetrically fixed on the tray conveyor seat 71 are provided for feeding the stator housing... Alternatively, the rotor can be clamped and fixed on the quick-release mounting base 73. The clamping and fixing assembly 77 includes a clamping and fixing seat 771 fixedly connected to the material tray conveyor seat 71 along the horizontal direction and a cam sliding block 773 slidably connected to the clamping and fixing seat 771 based on the first horizontal guide rail 772. A cam groove 774 is provided on the cam sliding block 773. A clamping guide seat 775 is fixedly connected to the clamping and fixing seat 771. A clamping abutment block 776 is slidably connected in the clamping guide seat 775 for abutting against the stator housing or rotor side wall to achieve clamping and fixing. A cam block is provided on the clamping abutment block 776 and slidably connected in the cam groove 774. Based on the sliding cam sliding block 773, the cam structure formed by the cam groove 774 and the cam block drives the clamping abutment block 776 to slide in the clamping guide seat 775, thereby controlling the extension and retraction of the clamping abutment block 776, and thus achieving the clamping and fixing of the stator housing or rotor.

A lifting pulley 34 is rotatably connected to the bottom of the lifting seat 33 near the lifting fixed seat 31. A sliding lifting block 36 is slidably connected to the lifting fixed seat 31 based on a second horizontal guide rail 35. A lifting inclined surface 37 is provided on the sliding lifting block 36 for the lifting pulley 34 to slide. A sliding lifting cylinder 38 is fixedly connected to the lifting fixed seat 31 to drive the sliding lifting block 36 to slide. The sliding lifting cylinder 38 extends and retracts to drive the sliding lifting block 36 to slide. The lifting inclined surface 37 abuts against the lifting pulley 34, thereby driving the lifting seat 33 to rise and fall, thus achieving stability of the lifting seat 33 during the lifting process while having a large load-bearing capacity.

Positioning abutment blocks 44 for abutting against the sidewalls of the stator housing are symmetrically slidably connected to both sides of the stator bearing positioning seat 42 along the sliding direction. A drive positioning abutment block 44 is fixedly connected to the stator bearing positioning seat 42. The positioning and abutting cylinder 45, which slides along the connecting block 44, drives the positioning and abutting seat to extend and retract, thereby abutting both ends of the stator housing and achieving stability during the transfer of the stator housing. An elastic positioning telescopic rod 46 for positioning the mounting holes on the rotor is fixedly connected vertically to the rotor bearing positioning seat 43.

A spring is provided between the hollow rod body and the positioning rod. The top of the positioning rod has a tapered structure for better... To facilitate positioning, when the stator and rotor transport assembly 5 transports the rotor to the rotor bearing positioning seat 43, the positioning rod is inserted into a mounting hole of the rotor to complete the positioning and fixing of the rotor. A lead screw transfer assembly 47, which drives the stator bearing positioning seat 42 and the rotor bearing positioning seat 43 to rotate, is fixedly connected to the base 1. The lead screw transfer assembly 47 includes a lead screw seat 471 fixedly connected to the base 1 and a drive lead screw shaft 472 rotatably connected to the lead screw seat 471, with its axis arranged parallel to the direction of the third horizontal guide rail 41.

A lead screw drive motor 474 that drives the drive lead screw shaft 472 to rotate is fixedly connected to the base 1. When it is necessary to transfer the stator housing and the rotor to the fitting station, the lead screw drive motor 474 drives the drive lead screw shaft 472 to rotate, thereby causing the lead screw nut 473 to slide, and then driving the stator bearing positioning seat 42 and the rotor bearing positioning seat 43 to be transferred along the third horizontal guide rail 41.

When it is necessary to move the horizontal conveying base 53 horizontally, the horizontal conveying drive motor 55 drives the first drive gear 56 to rotate. Through the engagement of the first drive gear 56 with the horizontal sliding rack 54, the horizontal conveying base 53 is moved along the fourth horizontal guide rail.

A second drive gear that meshes with the vertical lifting rack 59 is concentrically fixedly connected to the rotating shaft of the vertical transport drive motor 510. When the vertical transport seat 58 needs to move along the vertical direction, the vertical transport drive motor 510 drives the second drive gear to rotate. The second drive gear meshes with the vertical lifting rack 59, thereby driving the vertical lifting seat to move up and down along the first vertical guide rail 57. Transport blocks 512 are symmetrically slidably connected to both ends of the bottom of the vertical transport seat 58 along the horizontal sliding direction. Clamping and transporting cylinders 513 that drive the transport blocks 512 to slide are symmetrically fixedly connected to the vertical transport seat 58.

A lower pressure electric cylinder 67 is fixedly connected to the lower pressure fixing seat 63 along the vertical direction. During the rotor lifting and assembly process, the support rod 62 and the lower pressure seat 65 simultaneously press against the rotor from the upper and lower end faces respectively. The positioning pins 66 on the lower pressure seat 65 are inserted into the rotor mounting holes, further defining the circumferential position of the rotor, ensuring the stability of the rotor posture during the assembly process, avoiding the problem of rotor tilting during assembly, and ensuring the coaxiality of the rotor and stator housing during the assembly process.

The clamping component 69 includes a clamping fixing seat 691 fixedly connected to the base 1 and a horizontal clamping plate 692 slidably connected to the clamping fixing seat 691 along the horizontal direction.

During the fitting process, the pressing cylinder 67 drives the pressing base 65 to press down, thereby pressing the rotor into the stator housing.

Step 2: The stator and rotor transfer assembly 4 transfers and transports the rotor to the fitting station. The rotor synchronous pressing and supporting assembly 6 synchronously presses against the upper and lower end faces of the rotor and lifts the rotor to move upward to the set height and then stops. Step 3: The stator and rotor transfer assembly 4 transfers and transports the stator housing to the bottom of the rotor located at the fitting station, making the stator housing coincide with the axis of the rotor. Then, the rotor synchronous pressing assembly 6 drives the rotor to descend, thereby positioning and fitting the rotor into the stator housing to complete the assembly. Step 4: The stator and rotor conveying assembly 5 transports the assembled motor into the material box assembly.
