Description

Technical Field

[0001] This utility model relates to the technical field of automotive motor assembly equipment, and in particular to an automatic pressing equipment for automotive motor rotors and stators. Background Technology

[0002] The drive motor of a new energy vehicle consists of a rotor, a stator, and a housing.

[0003] In the existing technology, when assembling the rotor and stator, the rotor is usually lifted by a truss lifting device and then moved to the top of the housing on which the stator is installed. Then, the rotor is slowly lowered by a person supporting the lifting device and fitted into the stator. Finally, the stator is pressed into the locating pin on the housing by a hydraulic cylinder to complete the installation.

[0004] In the current installation process, especially when the rotor is manually hoisted into the stator, the rotor's strong magnetism attracts the stator, which can easily cause scratches on the stator's edges, leading to internal damage to the motor and affecting the yield. Moreover, the current method of manually inserting the rotor into the housing is inefficient. Utility Model Content

[0005] To address the aforementioned issues, this application provides a structurally sound automatic press-fitting device for automotive motor rotors and stators, thereby achieving automated and rapid installation and effectively ensuring installation efficiency and results.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An automatic pressing device for automotive motor rotors and stators includes a frame, a conveyor line running through the middle of the frame, and a transfer device supporting and conveying stator assemblies via the conveyor line; a pressing mechanism is installed on the frame above the conveyor line, and a gripping mechanism for gripping rotor assemblies is installed on the bottom surface of the pressing mechanism; multiple guide rods are installed on the bottom surface of the pressing mechanism inside the gripping mechanism, facing downwards, and abutting against the top surface of the rotor assembly; a lifting mechanism is installed on the frame below the conveyor line, directly below the pressing mechanism, and an upper push rod in the lifting mechanism passes upwards through the stator assembly and abuts against the bottom surface of the rotor assembly.

[0008] As a further improvement to the above technical solution:

[0009] Multiple clamping mechanisms are installed on the frames located on both sides of the conveyor line. The rotary cylinders in the clamping mechanisms work to press the clamping blocks downwards onto the stator assembly of the conveyor line.

[0010] The pressing mechanism includes a lifting seat mounted on the frame and moving up and down via a lifting guide rail. A press is mounted on the top surface of the frame, with the output end of the press connected to the lifting seat facing downwards. The gripping mechanism and the guide rod are mounted on the bottom surface of the lifting seat.

[0011] The top surface of the frame is also equipped with a lifting and balancing component, which is a single-acting cylinder with the output end facing downwards. The output end of the lifting and balancing component is connected to the top surface of the lifting seat.

[0012] The guide rod includes an abutment column, an elastic column, and a center column installed on the lifting seat. The elastic column and the center column are elastically installed on the lifting seat along the axial direction. The lifting seat is equipped with a pneumatic clamping device that fixes the elastic column and the center column axially. The bottom end of the center column abuts against the center of the top surface of the rotor assembly. The center column is located directly above the upper push rod in the axial direction. The bottom surface of the lifting seat is also equipped with a positioning pin facing downwards.

[0013] The gripping mechanism includes two sets of gripping mechanisms arranged opposite each other on both sides of the rotor assembly. One side of the gripping mechanism moves horizontally toward or away from the rotor assembly via a linear translational power. The structure of the gripping mechanism is as follows: it includes a linear gripping power source, a gripper rotatably mounted at the output end of the linear gripping power source, and a connecting rod. One end of the connecting rod is rotatably mounted in the middle of the gripper, and the other end of the connecting rod is rotatably mounted on the housing of the linear gripping power source. The gripper is driven by the linear gripping power source to grip the rotor assembly from below.

[0014] The lifting mechanism has the following structure: it includes a support mounted on the frame, a lifting seat supported above the support by a lifting guide assembly, and the lifting seat is driven by a lifting power to move up and down relative to the support; a reaction force support assembly is also installed between the support and the lifting seat, and after the lifting seat is lifted by the lifting power, the lifting seat supporting the stator assembly is supported by the reaction force support assembly.

[0015] The structure of the reaction support assembly is as follows: it includes a reaction support power installed on the support, and a reaction column is installed at the output end of the reaction support power via a moving block; a protruding column is installed with the bottom surface of the lifting seat facing downwards, and the reaction column is moved relative to the support by the reaction support power. The axial support of the reaction column is located directly below the protruding column or the reaction column and the protruding column are axially offset and far away from each other.

[0016] The support extends downward to the bottom surface and is equipped with a vertical base. An upward lifting power is installed on the vertical base. An upper lifting seat is installed at the downward output end of the upward lifting power. The upper lifting seat is slidably installed on the vertical base via an upper lifting guide rail. An upper lifting rod is installed on the upper lifting seat.

[0017] The frame is equipped with a transfer module arranged in a direction perpendicular to the conveyor line. The transfer module is equipped with a transfer seat that carries the rotor assembly. The transfer module transfers the rotor assembly to the area below the pressing mechanism.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model uses a gripping mechanism to grip the rotor assembly, so that the guide rod abuts against the top surface of the rotor assembly. The lifting mechanism lifts the stator assembly, and the upper lifting rod moves upward to abut against the bottom surface of the rotor assembly. The gripping mechanism releases, and combined with the downward pressing mechanism, the rotor assembly is reliably installed into the stator assembly, realizing automated and rapid installation, effectively ensuring installation efficiency and effect.

[0020] This utility model also has the following advantages:

[0021] During the downward pressing of the rotor assembly, the rotor assembly is relatively fixed and limited by the guide rod and the upper push rod. It moves down synchronously with the operation of the press in the pressing mechanism, while the stator assembly is fixed by the clamping mechanism. This effectively prevents the rotor assembly from being damaged by the strong magnetism, and effectively ensures the smooth installation process.

[0022] The lifting balance component is designed to balance the weight of the lifting seat and the rotor assembly held below it, especially to prevent the lifting seat from falling due to an unexpected power outage of the press. The lifting balance component can effectively and stably maintain the position of the lifting seat and rotor assembly. Attached Figure Description

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, an automatic pressing device for automotive motor rotors and stators in this embodiment includes a frame 1. A conveyor line 2 is arranged across the middle of the frame 1. The conveyor line 2 supports and conveys a stator assembly 20 via a transfer device 30. A pressing mechanism 5 is installed on the frame 1 above the conveyor line 2. A gripping mechanism 6 for gripping the rotor assembly 10 is installed on the bottom surface of the pressing mechanism 5. Multiple guide rods that abut against the top surface of the rotor assembly 10 are installed on the pressing mechanism 5 with the bottom surface facing downward inside the gripping mechanism 6. A lifting mechanism 3 is installed on the frame 1 below the conveyor line 2. The lifting mechanism 3 is located directly below the pressing mechanism 5. The upper push rod 35 of the lifting mechanism 3 passes upward through the stator assembly 20 and abuts against the bottom surface of the rotor assembly 10.

[0037] In use, the gripping mechanism 6 grips the rotor assembly 10, causing the guide rod to abut against the top surface of the rotor assembly 10. The lifting mechanism 3 lifts the stator assembly 20, and the upper push rod 35 moves upward to abut against the bottom surface of the rotor assembly 10. The gripping mechanism 6 releases, and combined with the downward pressing mechanism 5, the rotor assembly 10 is reliably installed into the stator assembly 20.

[0038] Multiple sets of clamping mechanisms 7 are installed on the frame 1 located on both sides of the conveyor line 2. The rotary cylinder in the clamping mechanism 7 works to press the clamping block down onto the stator assembly 20 of the conveyor line 2.

[0039] In this embodiment, when the rotor assembly 10 is pressed down, the rotor assembly 10 is relatively fixed and limited by the guide rod and the upper push rod 35. It moves down synchronously with the operation of the press 52 in the pressing mechanism 5. The stator assembly 20 is fixed by the clamping mechanism 7, thereby effectively preventing the rotor assembly 10 from being damaged by collision due to strong magnetism, and effectively ensuring the smooth installation process.

[0040] The pressing mechanism 5 includes a lifting seat 53 that is mounted on the frame 1 and moves up and down via a lifting guide rail 54. A press 52 is mounted on the top surface of the frame 1, and the output end of the press 52 is connected and mounted on the lifting seat 53 with its downward facing end. A gripping mechanism 6 and a guide rod are mounted on the bottom surface of the lifting seat 53. Through the operation of the press 52, the lifting seat 53 is driven to move down, thereby pressing the rotor assembly 10 below the guide rod into the stator assembly 20.

[0041] The top surface of the frame 1 is also equipped with a lifting balance component 51. The lifting balance component 51 is a single-acting cylinder with the output end facing downward. The output end of the lifting balance component 51 is connected to the top surface of the lifting seat 53.

[0042] In this embodiment, the lifting balance component 51 is used to balance the weight of the lifting seat 53 and the rotor assembly 10 clamped below it, especially to prevent the lifting seat 53 from falling due to an unexpected power failure of the press 52. The lifting balance component 51 can effectively and stably maintain the position of the lifting seat 53 and the rotor assembly 10.

[0043] In actual use, air is filled into the lower cavity of the single-acting cylinder, causing the single-acting cylinder to retract and pull the lifting seat 53 upward; under the pulling action of the single-acting cylinder, the press 52 is activated.

[0044] like Figure 2 and Figure 4 As shown, the guide rod includes an abutment post 55, an elastic post 56, and a center post 58 mounted on the lifting seat 53. The elastic post 56 and the center post 58 are elastically mounted on the lifting seat 53 along the axial direction. The lifting seat 53 is equipped with a pneumatic clamping member 59 that fixes the elastic post 56 and the center post 58 axially. The bottom end of the center post 58 abuts against the center of the top surface of the rotor assembly 10. The center post 58 is located directly above the upper push rod 35 in the axial direction, effectively ensuring the suspension balance of the rotor assembly 10. The bottom surface of the lifting seat 53 is also equipped with a positioning pin 57 facing downwards. The conical bottom end of the positioning pin 57 is fitted downwards with the rotor assembly 10 to form accurate positioning.

[0045] like Figure 5As shown, the elastic column 56 is movably mounted on the lifting seat 53 via the bushing 50. An elastic element is installed between the elastic column 56 and the bottom surface of the lifting seat 53. The top end of the elastic column 56 passes upward through the lifting seat 53 and is equipped with a pneumatic clamping element 59. In use, the elastic element ensures that the bottom end of the elastic column 56 abuts against the top surface of the rotor assembly 10. After the gripping mechanism 6 clamps the rotor assembly 10, the pneumatic clamping element 59 actuates to clamp the elastic column 56 to maintain its current length.

[0046] Similarly, after the center column 58 passes upward through the lifting seat 53, a pneumatic clamping component 59 is installed. Elastic components are installed between the center column 58 and the lifting seat 53, and between the positioning pin 57 and the lifting seat 53, to effectively ensure contact or fitting with the rotor assembly 10.

[0047] In this embodiment, the pneumatic clamping component 59 can be a commercially available standard product, such as the clamping unit of Festo KPE series, which can hold the corresponding elastic column 56 and central column 58 in the circumferential direction to maintain the current height.

[0048] The gripping mechanism 6 includes two sets arranged opposite each other on both sides of the rotor assembly 10. One side of the gripping mechanism 6 moves horizontally toward or away from the rotor assembly 10 via a linear translational power 61, allowing for spatial avoidance when the press 52 is activated; for example... Figure 3 As shown, the gripping mechanism 6 has the following structure: it includes a gripping linear power 62, a gripper 64 is rotatably mounted on the output end of the gripping linear power 62, and a connecting rod 63. One end of the connecting rod 63 is rotatably mounted on the middle of the gripper 64, and the other end of the connecting rod 63 is rotatably mounted on the housing of the gripping linear power 62. The gripping linear power 62 drives the gripper 64 to grip the rotor assembly 10 from below.

[0049] In this embodiment, the grasping linear power 62 can be a cylinder or electric cylinder, etc., capable of outputting downward linear motion, which pushes the gripper 64 downward to... Figure 3 The rotor rotates counterclockwise upwards, thereby holding the rotor assembly 10 from below by the gripper 64.

[0050] like Figure 6 and Figure 7 As shown, the structure of the lifting mechanism 3 is as follows: it includes a support 31 mounted on the frame 1, and a lifting seat 32 is mounted on the support 31 via a lifting guide assembly 37. The lifting seat 32 is driven by the lifting power 34 to move up and down relative to the support 31. A reaction force support assembly is also installed between the support 31 and the lifting seat 32. After the lifting seat 32 is lifted by the lifting power 34, the lifting seat 32, which supports the stator assembly 20, is supported by the reaction force support assembly.

[0051] In this embodiment, the lifting power 34 is arranged on both sides of the lifting seat 32, and the reaction force support assembly is arranged on the other two sides of the lifting seat 32, thereby effectively ensuring the stability of lifting and supporting the lifting seat 32.

[0052] In this embodiment, the reaction force support component effectively ensures the lifting support for the lifting seat 32, the transfer carrier 30, and the stator assembly 20, reducing or even avoiding the force on the lifting power 34 when the press 52 moves downward.

[0053] In this embodiment, the lifting power 34 can be one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, or other mechanisms that can provide up-and-down movement power for the lifting seat 32.

[0054] The structure of the reaction support assembly is as follows: it includes a reaction support power 36 installed on the support 31, and a reaction column 361 is installed at the output end of the reaction support power 36 via a moving block; a protruding column 38 is installed on the bottom surface of the lifting seat 32, and the reaction column 361 is moved relative to the support 31 by the reaction support power 36. The axial support of the reaction column 361 is located directly below the protruding column 38 or the reaction column 361 and the protruding column 38 are axially offset and far away.

[0055] In this embodiment, during the lifting process, the lifting power 34 first lifts the lifting seat 32 relative to the support 31 to a preset height. Then, the reaction support power 36 moves the reaction column 361 to face the protrusion 38 directly below it. The lifting seat 32 then moves slightly downward and is supported on the reaction column 361 via the protrusion 38.

[0056] A support 31 extends downwards to form a vertical base, on which an upward lifting power 353 is mounted. An upward lifting seat 351 is mounted on the downward-facing output end of the upward lifting power 353. The upward lifting seat 351 is slidably mounted on the vertical base via an upward lifting guide rail 352. An upward lifting rod 35 is mounted on the upward lifting seat 351. The action of the upward lifting power 353 drives the upward lifting rod 35 to move upwards or downwards.

[0057] In this embodiment, the upward force 353 can be one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, or other mechanisms that can provide the upward and downward movement power for the upward rod 35.

[0058] In this embodiment, after the upper push rod 35 moves upward and abuts against the bottom surface of the rotor assembly 10, the gripping mechanism 6 retracts its grip on the rotor assembly 10, and the upper push rod 35 temporarily supports the rotor assembly 10; the combination between the upper push rod 35 and the guide rod realizes the temporary suspension of the rotor assembly 10.

[0059] In this embodiment, a stop assembly 33 can also be installed on the support 31. The stop assembly is driven to move up and down by the action of the stop cylinder, thereby limiting and stopping the moving transfer device 30 on the conveyor line 2 at a preset position.

[0060] A transfer module 40 is arranged inside the frame 1 along a direction perpendicular to the conveyor line 2. A transfer seat 4 for carrying the rotor assembly 10 is installed on the transfer module 40. The transfer module 40 transfers the rotor assembly 10 to the area below the pressing mechanism 5.

[0061] In this embodiment, the support of the transfer seat 4 for the rotor assembly 10 and the support of the transfer device 20 for the stator assembly 20 can both be achieved by combining support blocks and positioning pins to achieve stable support.

[0062] In this embodiment, the stator assembly 20 can be a simple stator assembly or a housing pre-installed with the stator assembly 20, depending on the actual assembly requirements.

[0063] The method of using this utility model is as follows:

[0064] The transfer module 40 is activated, and the rotor assembly 10 is transferred to the lower pressing mechanism 5 via the transfer seat 4. The gripping mechanism 6 moves downward and grips the rotor assembly 10. The pneumatic clamping component 59 clamps the guide rod, and the transfer seat 4 retracts. At the same time, the stator assembly 20, which is carried on the transfer carrier 30, moves to the lower pressing mechanism 5 via the conveyor line 2. The lifting power 34 in the lifting mechanism 3 is activated, and the transfer carrier 30 is lifted upward via the lifting seat 32. Then, the reaction force support 36 lifts the transfer carrier 30 upward via the lifting seat 32. The support and clamping mechanism 7 operates to limit and clamp the stator assembly 20; the upper lifting power 353 operates, causing the upper lifting rod 35 to move upward through the stator assembly 20 and abut against the bottom surface of the rotor assembly 10; the gripping mechanism 6 releases its grip on the rotor assembly 10, causing the rotor assembly 10 to temporarily suspend between the upper lifting rod 35 and the guide rod; the middle press 52 of the lower pressing mechanism 5 operates, driving the lifting seat 53, the guide rod, the rotor assembly 10, and the upper lifting rod 35 to move downward synchronously until the rotor assembly 10 is pressed down and fitted into the stator assembly 20.

[0065] This invention enables automated and rapid installation of the stator and rotor in automotive motors, effectively ensuring installation efficiency and results.

[0066] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
