[0003] The patent with the patent announcement number CN208386381U discloses a housing assembly device for a rare earth permanent magnet motor for automobiles, including a base. An installation device is provided on the top of the base. The installation device includes an installation plate, the installation plate is fixedly connected to the base. An installation groove is provided on the top of the installation plate, and a machine base is provided inside the installation groove. A rare earth permanent magnet motor main body is provided on the top of the machine base. A first sliding groove is provided on one side of the machine base, and a first pulley is provided inside the first sliding groove. The first pulley is slidably connected to the first sliding groove, and a first sliding plate is provided on the top of the first pulley. By providing the installation device, the first hydraulic rod and the second hydraulic rod respectively push the first sliding plate and the second sliding plate, and then the end cover on the end cover fixing mold and the wind cover on the wind cover fixing mold are respectively clamped on the rare earth permanent magnet motor main body, which is beneficial to improving the installation speed of the end cover and the wind cover, enhancing the accuracy of assembling the end cover and the wind cover on the rare earth permanent magnet motor main body, and improving the assembly efficiency.

[0004] However, there are still deficiencies in the current device: Although the device can improve the installation speed of the motor cover, when there is dirt attached to the inner wall of the cover during the installation process, it is easy to cause the non-parallel and regular posture between the motor main body and the cover, resulting in an inclined installation between the cover and the motor main body, thereby reducing the connection tightness between the cover and the motor main body. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a housing assembly device and method for a rare earth permanent magnet motor for automobiles, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a housing assembly device for a rare earth permanent magnet motor for an automobile, comprising an assembly table, a fixing frame is arranged at the center of the top of the assembly table, a motor body is arranged on the inner wall of the fixing frame, two electric slide rails are arranged on the top of the assembly table, the two electric slide rails are symmetrically distributed with the fixing frame as the center, and the two electric slide rails are independently operated, a sliding column is slidably installed inside the electric slide rail, a U-groove sliding frame is fixedly installed on the top of the sliding column, an L-shaped support plate is slidably installed on the bottom of the inner wall of the U-groove sliding frame, the top outer wall of the L-shaped support plate movably passes through the inside of the U-groove sliding frame, and the L The U-shaped support plate is fixedly installed with an arc clamping plate on one side near the center of the U-slot sliding frame, and an arc-shaped rubber pad is fixedly installed inside the arc clamping plate, and an arc guide plate is fixedly installed on the outer wall of the arc clamping plate, and a screw rod is rotatably installed on the outer wall of the screw rod, and the outer wall of the screw rod movably passes through the inside of the U-slot sliding frame, and a plurality of elastic telescopic rods are fixedly installed on the outer wall of the screw rod away from the center of the U-slot sliding frame, and a collision block is fixedly installed on the telescopic end of the elastic telescopic rod, and a plurality of hollow vibration columns are equidistantly and fixedly installed on the outer wall of the U-slot sliding frame. The motor body is placed inside the fixed frame, and the fixed frame is limited by the assembly table to ensure the stability of the motor body and other components during assembly. When the assembly of the machine front cover and the motor rear cover begins, the electric slide rail is started. The electric slide rails on the left and right sides of the top of the assembly table operate independently and do not have to be synchronized. The electric slide rail drives the sliding column to slide or reset in the direction close to the fixed frame inside itself, and the sliding column drives the U-groove sliding frame to move synchronously. When the motor front cover is placed in the U-groove sliding frame on the left side of the top of the assembly table, the outer wall of the motor front cover first contacts the arc surface of the arc guide plate close to the center of the U-groove sliding frame to generate a resistance force. At this time, the arc guide plate moves away from the center of the U-groove sliding frame through the resistance force. When the motor front cover falls below the outer wall of the arc guide plate, it is guided and resisted by the round surface of the arc guide plate to avoid blockage. At the same time, the arc guide plate drives the arc clamping plate to move synchronously away from the center of the U-groove sliding frame, and the arc clamping plate drives the arc rubber pad to move synchronously. When the motor front cover completely enters the arc clamping plate, the concave surface of the inner wall of the arc rubber pad contacts and fits with the outer wall of the motor front cover, and the arc clamping plate drives the L-shaped support plate to move synchronously along the bottom of the inner wall of the U-groove sliding frame. When the L-shaped support plate slides, the spring deforms synchronously, and then the L-shaped support plate is reset by the spring elastic force. At this time, the sliding column drives the arc clamping plate and the motor front cover to move toward the left end of the motor body until the motor front cover coincides with the left end of the motor body. The assembler fixes the two to complete the assembly work, and the same is true for the motor rear cover;When the L-shaped support plate moves away from the center of the U-groove sliding frame, it drives the screw rod to move synchronously. When the screw rod slides inside the U-groove sliding frame, it is limited by its own spiral groove, and the built-in block of the U-groove sliding frame constantly contacts the inner wall of the screw rod spiral groove, causing the screw rod to start rotating. The screw rod drives the elastic telescopic rod to rotate. During the process of the elastic telescopic rod driving the impact block to rotate, the arc surface of the outer wall of the impact block contacts and collides with the outer wall of the hollow vibration column, and a resistance force is generated. At this time, the hollow vibration column and the impact block vibrate through the impact force, and the arc splint drives the arc rubber pad to vibrate synchronously through the transmission of force. At the same time, the impact block relies on its own arc surface and the arc surface of the hollow vibration column to guide, so that the impact block drives the telescopic end of the elastic telescopic rod to shrink toward the inside of the fixed end, ensuring that the elastic telescopic end drives the impact block to cross the hollow vibration column. ;

[0007] According to the above technical solution, a spring is fixedly installed between the outer wall of the L-shaped support plate and the inner wall of the U-groove sliding frame, the bottom of the arc guide plate close to the center of the U-groove sliding frame is designed as a round surface, a number of the elastic telescopic rods are equidistantly distributed on the outer wall of the screw rod, the outer wall of the hollow vibration column is located on the arc motion trajectory of the impact block, and the U-groove sliding frame is provided with an anti-misalignment device close to the fixed frame to facilitate the installation personnel to observe the orientation when installing the motor body and the motor front cover and rear cover.

[0008] According to the above technical solution, the anti-dislocation device includes a cross bar, a receiving ring, an arc-shaped guard plate, a telescopic plate and a hinged plate. The end of the cross bar away from the outer wall of the fixed frame is fixedly installed on the outer wall of the U-groove sliding frame, the receiving ring is fixedly installed on the side away from the outer wall of the fixed frame, and the end of the cross bar close to the outer wall of the fixed frame is fixedly installed. The side of the arc-shaped guard plate away from the outer wall of the fixed frame is fixedly installed on the outer wall of the U-groove sliding frame, and the side of the telescopic plate close to the outer wall of the electric slide rail is fixedly installed on the outer wall of the receiving ring. The hinged plate is hinged on the telescopic frame through a torsion spring. The U-groove sliding frame drives the cross bar to move synchronously, and the cross bar drives the receiving ring to move synchronously. The U-groove sliding frame drives the arc guard plate to move synchronously, and the arc guard plate shares the gravity of the receiving ring. At the same time, the receiving ring drives the telescopic plate to move synchronously, and the telescopic end of the telescopic plate drives the hinged plate to move synchronously. The hinge axis between the hinged plate and the telescopic plate begins to rotate after being subjected to external force. At this time, the hinged plate pushes the telescopic end of the telescopic plate to extend away from the outer wall of the receiving ring with its own hinge axis as the axis.

[0009] According to the above technical solution, the concave surface of the inner wall of the arc-shaped guard plate is fixedly connected to the outer wall of the receiving ring, the fixed end and the telescopic end of the telescopic plate are both provided with scale grooves, and the inside of the receiving ring is provided with an anti-deviation device for ensuring stable installation of the front cover and the rear cover of the motor.

[0010] According to the above technical scheme, the anti-misalignment device also includes a kinetic energy ring and a plurality of mirror panels. The kinetic energy ring penetrates through and is slidably installed inside the receiving ring on the side away from the outer wall of the fixed frame. A spring is arranged between the kinetic energy ring and the receiving ring. The side of the plurality of mirror panels away from the outer wall of the fixed frame is hinged to the outer wall of the kinetic energy ring through a torsion spring. The side of the mirror panel away from the kinetic energy ring contacts the upper part of the outer wall of the motor body. At the same time, the receiving ring drives the kinetic energy ring to move synchronously, and the kinetic energy ring drives the mirror panel to move synchronously. When the bottom of the mirror panel contacts the outer wall of the motor body to generate a resistance force, the hinge axis of the mirror panel starts to rotate, prompting the mirror panel to rotate in an arc shape with its own hinge axis as the axis, that is, the mirror panel gradually rotates from the inclined surface to a direction parallel to the outer wall of the motor body.

[0011] According to the above technical scheme, the anti-deviation device includes an articulated rod, a swing plate, a rotating rod and a rubber wheel, the top of the articulated rod is hinged at the inner wall of the kinetic energy ring through a torsion spring, the side of the swing plate away from the center of the kinetic energy ring is hinged at the inner wall of the receiving ring through a torsion spring, both ends of the rotating rod are rotatably installed on the inner wall of the U-shaped groove of the swing plate, the rubber wheel penetrates inside and is fixedly installed on the outer wall of the rotating rod, and when the kinetic energy ring contracts toward the inside of the receiving ring, the articulated rod is driven to move synchronously, and the hinge shaft between the bottom end of the articulated rod and the swing plate begins to rotate through thrust, prompting the swing plate to start rotating in a direction away from the outer wall of the fixed frame with the articulated shaft between itself and the receiving ring as the axis, prompting the swing plate to be distributed in an inclined posture, and in the process of connecting the motor housing and the motor body, the outer wall of the motor housing contacts the outer wall of the rubber wheel to generate friction, and the rubber wheel generates a rotational force through friction and drives the rotating rod to rotate along the inner wall of the U-shaped groove of the swing plate, and the swing plate is restricted by the articulated rod to prompt the outer wall of the rubber wheel to always be in close contact with the motor housing.

[0012] According to the above technical solution, the swing plate is hinged to the bottom of the hinge rod at one side close to the outer wall of the fixing frame, a U-shaped groove is provided at one end of the swing plate close to the center of the receiving ring, and an arc groove is provided on the outer wall of the rotating rod.

[0013] According to the above technical scheme, the anti-deviation device also includes a sliding rod, a sliding ring, a limiting plate and a plurality of resistance rods, wherein the sliding rod is slidably installed at one end close to the center of the rubber wheel inside the arc groove of the rotating rod, the inner wall of the sliding ring is fixedly installed at the end of the sliding rod away from the center of the rubber wheel, the limiting plate is fixedly installed between the outer wall of the sliding ring and the top of the inner wall of the U-shaped groove of the swing plate, and the plurality of resistance rods are equidistant and fixedly installed on the side of the sliding ring close to the rubber wheel, and the end of the resistance rod close to the center of the swing plate contacts the outer wall of the rubber wheel. When the rotating rod rotates, the arc groove restricts the sliding rod, so that the sliding rod can slide left and right along the inside of the arc groove of the rotating rod, the sliding rod drives the sliding ring to move synchronously, and the sliding ring drives the limiting plate to slide synchronously along the inner wall of the U-shaped groove of the swing plate, and at the same time, when the sliding ring moves to the left, it drives the resistance rod to resist the rubber wheel to deform.

[0014] A method for using a housing assembly device for a rare earth permanent magnet motor for an automobile comprises the following steps: S1: Place the motor body inside the fixing frame, and use the assembly table to limit the fixing frame to ensure the stability of the motor body and other parts during assembly. When the motor front cover and the motor rear cover are assembled, start the electric slide rail. The electric slide rails on the left and right sides of the top of the assembly table operate independently and do not have to be synchronized. The electric slide rail drives the sliding column to slide or reset in the direction close to the fixing frame; S2: The sliding column drives the U-groove sliding frame to move synchronously. When the motor front cover is placed inside the U-groove sliding frame on the left side of the top of the assembly table, the outer wall of the motor front cover first contacts the arc surface of the arc guide plate close to the center of the U-groove sliding frame to generate a resistance force. At this time, the arc guide plate moves away from the center of the U-groove sliding frame due to the resistance force. S3: When the motor front cover falls below the outer wall of the arc guide plate, the circular surface of the arc guide plate is used for guiding and resisting to avoid blocking. At the same time, the arc guide plate drives the arc clamping plate to move synchronously away from the center of the U-groove sliding frame, and the arc clamping plate drives the arc rubber pad to move synchronously. When the motor front cover completely enters the arc clamping plate, the concave surface of the inner wall of the arc rubber pad contacts and fits with the outer wall of the motor front cover, and the arc clamping plate drives the L-shaped support plate to move synchronously along the bottom of the inner wall of the U-groove sliding frame. When the L-shaped support plate slides, the spring is deformed synchronously, and then the L-shaped support plate is reset by the elastic force of the spring; S4: At this time, the sliding column drives the arc-shaped clamping plate and the motor front cover to move toward the left end of the motor body until the motor front cover overlaps with the left end of the motor body. The assembler fixes the two to complete the assembly work, and the same is true for the motor rear cover; S5: When the L-shaped support plate moves away from the center of the U-groove sliding frame, it drives the screw rod to move synchronously. When the screw rod slides inside the U-groove sliding frame, it is restricted by its own spiral groove, and the built-in block of the U-groove sliding frame continuously contacts the inner wall of the screw rod's spiral groove, causing the screw rod to start rotating. The screw rod drives the elastic telescopic rod to rotate. During the process of the elastic telescopic rod driving the impact block to rotate, the arc surface of the outer wall of the impact block contacts and collides with the outer wall of the hollow vibration column, and a resistance force is generated. At this time, the hollow vibration column and the impact block vibrate through the impact force, and the transmission of force causes the arc splint to drive the arc rubber pad to vibrate synchronously. At the same time, the impact block relies on its own arc surface and the arc surface of the hollow vibration column to guide, so that the impact block drives the telescopic end of the elastic telescopic rod to shrink toward the inside of the fixed end, ensuring that the telescopic end of the elastic telescopic rod drives the impact block to cross the hollow vibration column.

[0015] The present invention provides a housing assembly device and method for a rare earth permanent magnet motor for automobiles, which has the following beneficial effects: (1) The present invention realizes the rapid and adaptive adjustment of the motor housing into the arc clamping plate by cooperating with the sliding column, U-groove sliding frame, L-shaped support plate, arc clamping plate, arc rubber pad, arc guide plate, screw rod, elastic telescopic rod, impact block and hollow vibration column, so as to reduce manual intervention, enable the arc clamping plate to clamp motor housings of different sizes, and increase the friction between the arc clamping plate and the motor housing by the arc rubber pad, thereby enhancing the clamping stability and ensuring good stability during the assembly process of the housing and the motor body; and realizes that the arc rubber pad is closely fitted with the irregular outer wall of the motor housing by relying on the vibration force without hindering the movement trajectory of the elastic telescopic rod, thereby reducing the clamping gap, and at the same time relying on the vibration force to shake off the solid dirt inside the housing, so as to avoid the solid dirt causing the motor body and the housing to be installed in an inclined posture, thereby avoiding the reduction of the connection tightness between the housing and the motor body.

[0016] (2) The present invention sets an anti-misalignment device, and cooperates with a U-groove sliding frame, a cross bar, a receiving ring, an arc-shaped guard plate, a telescopic plate, a hinged plate, a kinetic energy ring and a mirror plate. The receiving ring protects and supports the motor housing, thereby preventing the housing from falling and damaging the electric slide rail due to installation errors. At the same time, as the motor body and the housing gradually approach each other, the extension range of the telescopic plate gradually increases. The scale groove on the outer wall of the telescopic plate facilitates the staff to make timely judgments on whether the housing is located at the center of the receiving ring, that is, whether it is facing the connection end of the motor body. At the same time, the mirror plate can map the connection scene when the housing and the motor body are installed, which facilitates the installers to determine the installation hole positions of the two, ensures that the fixing screw enters the installation hole position horizontally, avoids the occurrence of connection misalignment caused by installation misalignment, and saves installation alignment time.

[0017] (3) The present invention provides an anti-deviating device, and cooperates with a kinetic energy ring, a hinged rod, a swing plate, a rotating rod, a rubber wheel, a sliding rod, a sliding ring, a limit plate and a resistance rod to enable the motor housing to be centrally extruded and guided by the rubber wheel during the installation process with the motor body, thereby preventing the housing from being slightly displaced due to equipment vibration or external force interference during the installation process; at the same time, the reciprocating deformation of a plurality of circularly distributed rubber wheels effectively centered the motor housing, thereby correcting the position of the motor housing that deviates from the center position of the arc-shaped clamping plate, ensuring that the motor housing and the motor body are always in a central installation position during the installation process, and ensuring that the installation holes of the motor housing and the motor body are always aligned and not offset.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Please refer to Figures 1 - 8, an embodiment of the present invention is: a housing assembly device for a rare earth permanent magnet motor for automobiles, including an assembly table 1. At the center of the top of the assembly table 1, a fixing frame 2 is provided. Inside the inner wall of the fixing frame 2, a motor main body 3 is arranged. On the top of the assembly table 1, two electric sliding rails 31 are provided. The two electric sliding rails 31 are symmetrically distributed with the fixing frame 2 as the center, and the two electric sliding rails 31 operate independently. Inside the electric sliding rail 31, a sliding column 6 is slidably installed. At the top of the sliding column 6, a U-groove sliding frame 7 is fixedly installed. At the bottom of the inner wall of the U-groove sliding frame 7, an L-shaped support plate 8 is slidably installed. The top outer wall of the L-shaped support plate 8 movably penetrates inside the U-groove sliding frame 7. On one side of the L-shaped support plate 8 close to the center of the U-groove sliding frame 7, an arc-shaped clamping plate 9 is fixedly installed. Inside the arc-shaped clamping plate 9, an arc-shaped rubber pad 10 is fixedly installed. On the outer wall of the arc-shaped clamping plate 9, an arc-shaped guide plate 11 is fixedly installed. On the outer wall of the arc-shaped clamping plate 9, a lead screw 12 is rotatably installed. The outer wall of the lead screw 12 movably penetrates inside the U-groove sliding frame 7. At one end of the lead screw 12 away from the center of the U-groove sliding frame 7, a number of elastic telescopic rods 13 are fixedly installed on the outer wall. At the telescopic end of the elastic telescopic rod 13, an impact block 14 is fixedly installed. On the outer wall of the U-groove sliding frame 7, a number of hollow vibration columns 15 are fixedly installed at equal intervals. Through the above cooperation, the motor housing can be quickly and adaptively adjusted to be placed inside the arc-shaped clamping plate 9, reducing manual participation, enabling the arc-shaped clamping plate 9 to clamp motor housings with different diameters, and increasing the friction between the arc-shaped clamping plate 9 and the motor housing through the arc-shaped rubber pad 10, thereby enhancing the clamping stability and ensuring good stability during the assembly process of the housing and the motor main body 3; through the above cooperation, while not interfering with the movement trajectory of the elastic telescopic rod 13, the arc-shaped rubber pad 10 is urged to closely fit the non-regular outer wall of the motor housing by the vibration force, reducing the clamping gap, and at the same time, the solid dirt inside the housing is shaken off by the vibration force, preventing the solid dirt from causing the motor main body 3 and the housing to be installed in an inclined posture and avoiding a reduction in the connection tightness between the housing and the motor main body 3.

[0022] A spring is fixedly installed between the outer wall of the L-shaped support plate 8 and the inner wall of the U-groove sliding frame 7. The bottom on one side of the arc-shaped guide plate 11 close to the center of the U-groove sliding frame 7 is designed as a circular surface. The number of elastic telescopic rods 13 is equally distributed on the outer wall of the lead screw 12. The outer wall of the hollow vibration column 15 is located on the arc-shaped movement trajectory of the impact block 14. On one side of the U-groove sliding frame 7 close to the fixing frame 2, an anti-misalignment device 4 is provided to facilitate the installer to observe the orientation during the installation of the motor main body 3, the motor front cover, and the rear cover.

[0023] When in use, the motor body 3 is placed inside the fixing frame 2, and the fixing frame 2 is limited by the assembly table 1 to ensure the stability of the motor body 3 and other components during assembly. When the motor front cover and the motor rear cover are assembled, the electric slide rail 31 is started. The electric slide rails 31 on the left and right sides of the top of the assembly table 1 operate independently and do not have to be synchronized. The electric slide rail 31 drives the sliding column 6 to slide or reset in the direction close to the fixing frame 2 inside itself, and the sliding column 6 drives the U-groove sliding frame 7 to move synchronously. When the motor front cover is placed inside the U-groove sliding frame 7 on the left side of the top of the assembly table 1, the outer wall of the motor front cover first contacts with the arc surface of the arc guide plate 11 close to the center of the U-groove sliding frame 7 to generate a resistance force. At this time, the arc guide plate 11 moves away from the center of the U-groove sliding frame 7 through the resistance force. When the motor front cover falls below the outer wall of the arc guide plate 11, it is guided and resisted by the round surface of the arc guide plate 11 to avoid obstruction. At the same time, the arc guide plate 11 drives the arc clamping plate 9 to move synchronously away from the center of the U-groove sliding frame 7 When the motor cover is completely inserted into the arc clamping plate 9, the concave surface of the inner wall of the arc rubber pad 10 contacts and fits with the outer wall of the motor cover, and the arc clamping plate 9 drives the L-shaped support plate 8 to move synchronously along the bottom of the inner wall of the U-groove sliding frame 7. When the L-shaped support plate 8 slides, it resists the spring and deforms synchronously. Then, the L-shaped support plate 8 is reset by the spring elastic force. At this time, the sliding column 6 drives the arc clamping plate 9 and the motor front cover to move toward the left end of the motor body 3 until the motor front cover coincides with the left end of the motor body 3. The assembler fixes the two to complete the assembly work. The same is true for the motor rear cover. Through the above cooperation, the motor housing is quickly and adaptively adjusted to be placed in the arc clamping plate 9 to reduce manual participation, so that the arc clamping plate 9 can clamp motor housings of different diameters, and the friction between the arc clamping plate 9 and the motor housing is increased by the arc rubber pad 10, thereby enhancing the clamping stability and ensuring the good stability of the housing and the motor body 3 during the assembly process.When the L-shaped support plate 8 moves away from the center direction of the U-groove sliding frame 7, it drives the screw rod 12 to move synchronously. When the screw rod 12 slides inside the U-groove sliding frame 7, it is restricted by its own spiral groove, and the built-in block of the U-groove sliding frame 7 continuously contacts the inner wall of the spiral groove of the screw rod 12, causing the screw rod 12 to start rotating. The screw rod 12 drives the elastic telescopic rod 13 to rotate. During the process of the elastic telescopic rod 13 driving the impact block 14 to rotate, the arc surface of the outer wall of the impact block 14 contacts and collides with the outer wall of the hollow vibration column 15, and a resistance force is generated. At this time, the hollow vibration column 15 and the impact block 14 vibrate through the impact force, and the arc splint 9 drives the arc rubber pad 10 synchronously through the transmission of force. Vibration, while the impact block 14 relies on its own arc surface and the arc surface of the hollow vibration column 15 to guide, so that the impact block 14 drives the telescopic end of the elastic telescopic rod 13 to shrink inside the fixed end, ensuring that the telescopic end of the elastic telescopic rod 13 drives the impact block 14 to cross the hollow vibration column 15. Through the above cooperation, it is realized that the movement trajectory of the elastic telescopic rod 13 is not hindered, and the arc rubber pad 10 is closely fitted with the irregular outer wall of the motor housing by relying on the vibration force to reduce the clamping gap. At the same time, the solid dirt inside the housing is shaken off by relying on the vibration force, so as to avoid the solid dirt causing the motor body 3 and the housing to be installed in an inclined posture, and to avoid the connection tightness between the housing and the motor body 3 is reduced. ;

The plate 45 is hinged between the side of the telescopic plate 44 away from the U-slot sliding frame 7 and the outer wall of the fixed frame 2 through a torsion spring. Through the above cooperation, the motor housing is protected and supported by the receiving ring 42 to avoid the housing from falling and damaging the electric slide rail 31 due to installation errors. At the same time, as the motor body 3 and the housing gradually approach each other, the extension range of the telescopic plate 44 gradually increases. Relying on the scale groove on the outer wall of the telescopic plate 44, the staff can make timely judgments on whether the housing is located in the center of the receiving ring 42, that is, whether it is facing the connecting end of the motor body 3.

[0025] The concave surface of the inner wall of the arc-shaped guard plate 43 is fixedly connected to the outer wall of the receiving ring 42. The fixed end and the telescopic end of the telescopic plate 44 are both provided with scale grooves. The receiving ring 42 is provided with an anti-deviating device 5 for ensuring the stable installation of the front cover and the rear cover of the motor.

A spring is provided between the kinetic energy ring 46 and the receiving ring 42. One side of the plurality of mirror panels 47 away from the outer wall of the fixed frame 2 is hinged to the outer wall of the kinetic energy ring 46 through a torsion spring. One side of the mirror panel 47 away from the kinetic energy ring 46 contacts the upper part of the outer wall of the motor main body 3. Through the above cooperation, the mirror panel 47 can map the connection situation during the installation of the housing and the motor main body 3, facilitating the installer to determine the installation holes of the two, ensuring that the fixing screw enters the installation hole horizontally to avoid connection misalignment caused by installation misalignment, and saving the installation alignment time.

[0027] During use, the U-groove sliding frame 7 drives the cross bar 41 to move synchronously. The cross bar 41 drives the receiving ring 42 to move synchronously. The U-groove sliding frame 7 drives the arc-shaped guard plate 43 to move synchronously. The arc-shaped guard plate 43 shares the gravity of the receiving ring 42. At the same time, the receiving ring 42 drives the telescopic plate 44 to move synchronously. The telescopic end of the telescopic plate 44 drives the hinge plate 45 to move synchronously. The hinge shaft between the hinge plate 45 and the telescopic plate 44 starts to rotate under an external force. At this time, the hinge plate 45 pushes the telescopic end of the telescopic plate 44 to extend away from the outer wall of the receiving ring 42 with its own hinge shaft as the axis. Through the above cooperation, the motor housing is protected and received by relying on the receiving ring 42 to avoid damage to the electric slide rail 31 caused by the falling of the housing due to installation mistakes. At the same time, as the motor main body 3 and the housing gradually approach, the extension range of the telescopic plate 44 gradually increases. The scale groove on the outer wall of the telescopic plate 44 facilitates the staff to timely judge whether the housing is at the center of the receiving ring 42, that is, whether it is directly opposite the connection end of the motor main body 3. At the same time, the receiving ring 42 drives the kinetic energy ring 46 to move synchronously. The kinetic energy ring 46 drives the mirror panel 47 to move synchronously. When the bottom of the mirror panel 47 contacts the main body of the outer wall of the motor main body 3 and generates a contact force, the hinge shaft of the mirror panel 47 starts to rotate, causing the mirror panel 47 to rotate in an arc with its own hinge shaft as the axis, that is, the mirror panel 47 gradually rotates from an inclined surface to a direction parallel to the outer wall of the motor main body 3. Through the above cooperation, the mirror panel 47 can map the connection situation during the installation of the housing and the motor main body 3, facilitating the installer to determine the installation holes of the two, ensuring that the fixing screw enters the installation hole horizontally to avoid connection misalignment caused by installation misalignment, and saving the installation alignment time.

[0028] Please refer to Figures 1 - 8 , on the basis of the above embodiment, another embodiment of the present invention further includes an anti-offset device 5; The anti-offset device 5 includes a hinge rod 51, a swing plate 52, a rotating rod 53 and a rubber wheel 54. The top of the hinge rod 51 is hinged to the inner wall of the kinetic energy ring 46 through a torsion spring. One side of the swing plate 52 away from the center of the kinetic energy ring 46 is hinged to the inner wall of the receiving ring 42 through a torsion spring. Both ends of the rotating rod 53 are rotatably installed on the inner wall of the U-shaped groove of the swing plate 52. The rubber wheel 54 penetrates and is fixedly installed on the outer wall of the rotating rod 53. Through the above cooperation, during the installation process of the motor housing and the motor main body 3, the rubber wheel 54 is used to center and squeeze the motor housing, preventing the housing from being slightly displaced due to equipment vibration or external interference during the installation movement process.

[0029] One side of the swing plate 52 close to the outer wall of the fixed frame 2 is hinged to the bottom of the hinge rod 51. One end of the swing plate 52 close to the center of the receiving ring 42 is provided with a U-shaped groove. The outer wall of the rotating rod 53 is provided with an arc-shaped groove.

[0030] The anti-offset device 5 further includes a sliding rod 55, a sliding ring 56, a limiting plate 57 and a plurality of abutting rods 58. One end of the sliding rod 55 close to the center of the rubber wheel 54 is slidably installed inside the arc-shaped groove of the rotating rod 53. The inner wall of the sliding ring 56 is fixedly installed at one end of the sliding rod 55 away from the center of the rubber wheel 54. The limiting plate 57 is fixedly installed between the outer wall of the sliding ring 56 and the top of the inner wall of the U-shaped groove of the swing plate 52. A plurality of abutting rods 58 are equidistantly and fixedly installed on one side of the sliding ring 56 close to the rubber wheel 54. One end of the abutting rod 58 close to the center of the swing plate 52 contacts the outer wall of the rubber wheel 54. Through the above cooperation, the reciprocating deformation of the plurality of rubber wheels 54 distributed in a circular shape is effectively used to well center and squeeze the motor housing, thereby correcting the orientation of the motor housing deviated from the center orientation of the arc-shaped clamping plate 9, ensuring that the motor housing and the motor main body 3 are always in the centered installation orientation during the installation process, and ensuring that the installation holes of the motor housing and the motor main body 3 are always directly opposite and do not deviate.

[0031] When in use, the kinetic energy ring 46 contracts toward the inside of the receiving ring 42, driving the hinge rod 51 to move synchronously, and the hinge shaft between the bottom end of the hinge rod 51 and the swing plate 52 begins to rotate through the thrust, causing the swing plate 52 to start rotating with the hinge shaft between itself and the receiving ring 42 as the axis in the direction away from the outer wall of the fixing frame 2, causing the swing plate 52 to be distributed in an inclined posture. In the process of connecting the motor housing and the motor body 3, the outer wall of the motor housing contacts the outer wall of the rubber wheel 54 to generate friction. The rubber wheel 54 generates a rotational force through the friction and drives the rotating rod 53 to rotate along the inner wall of the U-shaped groove of the swing plate 52, and the swing plate 52 is restricted by the hinge rod 51, causing the outer wall of the rubber wheel 54 to always be in close contact with the motor housing. Through the above cooperation, the motor housing is forced to rely on the rubber wheel 54 to squeeze and guide the motor housing in the center during the installation process with the motor body 3 to prevent the shell from being The body may be slightly offset during the installation movement due to equipment vibration or external force interference; when the rotating rod 53 rotates, the arc groove restricts the sliding rod 55, so that the sliding rod 55 can slide left and right along the inside of the arc groove of the rotating rod 53, and the sliding rod 55 drives the sliding ring 56 to move synchronously, and the sliding ring 56 drives the limiting plate 57 to slide synchronously along the inner wall of the U-shaped groove of the swing plate 52. At the same time, when the sliding ring 56 moves to the left, it drives the resistance rod 58 to resist the rubber wheel 54 to deform. Through the above cooperation, the reciprocating deformation of multiple circularly distributed rubber wheels 54 effectively squeezes the motor housing in a good center, thereby correcting the position of the motor housing that deviates from the center position of the arc clamping plate 9, ensuring that the motor housing and the motor body 3 are always in the center installation position during the installation process, and ensuring that the mounting holes of the motor housing and the motor body 3 are always directly opposite and not offset.

[0032] A method for using a housing assembly device for a rare earth permanent magnet motor for an automobile comprises the following steps: S1: The motor body 3 is placed inside the fixing frame 2, and the fixing frame 2 is limited by the assembly table 1 to ensure the stability of the motor body 3 and other components during assembly. When the motor front cover and the motor rear cover are assembled, the electric slide rail 31 is started. The electric slide rails 31 on the left and right sides of the top of the assembly table 1 operate independently and do not have to be synchronized. The electric slide rails 31 drive the sliding column 6 to slide or reset in the direction close to the fixing frame 2; S2: The sliding column 6 drives the U-groove sliding frame 7 to move synchronously. When the motor front cover is placed inside the U-groove sliding frame 7 on the left side of the top of the assembly table 1, the outer wall of the motor front cover first contacts the arc surface of the arc guide plate 11 close to the center of the U-groove sliding frame 7 to generate a resistance force. At this time, the arc guide plate 11 moves away from the center of the U-groove sliding frame 7 due to the resistance force. S3: When the motor front cover falls below the outer wall of the arc guide plate 11, the circular surface of the arc guide plate 11 is used for guiding and resisting to avoid blocking. At the same time, the arc guide plate 11 drives the arc clamping plate 9 to move synchronously away from the center of the U-groove sliding frame 7, and the arc clamping plate 9 drives the arc rubber pad 10 to move synchronously. When the motor front cover completely enters the arc clamping plate 9, the concave surface of the inner wall of the arc rubber pad 10 contacts and fits with the outer wall of the motor front cover, and the arc clamping plate 9 drives the L-shaped support plate 8 to move synchronously along the bottom of the inner wall of the U-groove sliding frame 7. When the L-shaped support plate 8 slides, the spring resists and deforms synchronously, and then the L-shaped support plate 8 is reset by the elastic force of the spring. S4: At this time, the sliding column 6 drives the arc-shaped clamping plate 9 and the motor front cover to move toward the left end of the motor body 3 until the motor front cover overlaps with the left end of the motor body 3. The assembler fixes the two to complete the assembly work, and the same is true for the motor rear cover; S5: When the L-shaped support plate 8 moves away from the center direction of the U-groove sliding frame 7, it drives the screw rod 12 to move synchronously. When the screw rod 12 slides inside the U-groove sliding frame 7, it is restricted by its own spiral groove, and the built-in block of the U-groove sliding frame 7 continuously contacts the inner wall of the spiral groove of the screw rod 12, causing the screw rod 12 to start rotating. The screw rod 12 drives the elastic telescopic rod 13 to rotate. During the process of the elastic telescopic rod 13 driving the impact block 14 to rotate, the arc surface of the outer wall of the impact block 14 contacts and collides with the outer wall of the hollow vibration column 15, and a resistance force is generated. At this time, the hollow vibration column 15 and the impact block 14 vibrate through the impact force, and the transmission of force causes the arc splint 9 to drive the arc rubber pad 10 to vibrate synchronously. At the same time, the impact block 14 relies on its own arc surface and the arc surface of the hollow vibration column 15 to guide, so that the impact block 14 drives the telescopic end of the elastic telescopic rod 13 to retract toward the inside of the fixed end, ensuring that the telescopic end of the elastic telescopic rod 13 drives the impact block 14 to cross the hollow vibration column 15.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

9. A method of using an outer shell assembly device for a rare earth permanent magnet motor for an automobile, which uses the outer shell assembly device for a rare earth permanent magnet motor for an automobile described in claim 8, characterized in that, It includes the following steps: S1: Place the motor main body (3) inside the fixed frame (2). The assembly table (1) limits the fixed frame (2) to ensure the stability during the assembly of components such as the motor main body (3). When the assembly work of the motor front cover and the motor rear cover starts, start the electric slide rail (31). The electric slide rails (31) on the left and right sides of the top of the assembly table (1) operate independently and do not have to be synchronized. The electric slide rail (31) drives the sliding column (6) to slide or reset in its own interior towards the direction close to the fixed frame (2). S2: The sliding column (6) drives the U-groove sliding frame (7) to move synchronously. When the motor front cover is placed inside the U-groove sliding frame (7) on the left side of the top of the assembly table (1), the outer wall of the motor front cover first contacts the arc surface of the arc surface guide plate (11) close to the center of the U-groove sliding frame (7) to generate a contact force. At this time, the arc surface guide plate (11) moves away from the center of the U-groove sliding frame (7) through the contact force. S3: When the front motor cover drops to below the outer wall of the arc-shaped guide plate (11), it is guided and resisted through the circular surface of the arc-shaped guide plate (11) to avoid blockage. At the same time, the arc-shaped guide plate (11) drives the arc-shaped clamping plate (9) to move synchronously in a direction away from the center of the U-groove sliding frame (7). The arc-shaped clamping plate (9) drives the arc-shaped rubber pad (10) to move synchronously. After the front motor cover completely enters the inside of the arc-shaped clamping plate (9), the concave surface of the inner wall of the arc-shaped rubber pad (10) contacts and fits with the outer wall of the front motor cover. And the arc-shaped clamping plate (9) drives the L-shaped support plate (8) to move synchronously along the bottom of the inner wall of the U-groove sliding frame (7). When the L-shaped support plate (8) slides, the contact spring deforms synchronously. Then the L-shaped support plate (8) returns to its original position by the elastic force of the spring; S4: At this time, the sliding column (6) drives the arc-shaped clamping plate (9) and the front motor cover to move towards the left end of the motor body (3). When the front motor cover coincides with the left end of the motor body (3), the assembler fixes the two to complete the assembly work. The same applies to the rear motor cover; S5: When the L-shaped support plate (8) moves in a direction away from the center of the U-groove sliding frame (7), it drives the lead screw (12) to move synchronously. When the lead screw (12) slides inside the U-groove sliding frame (7), due to the limitation of its own spiral groove and the continuous contact between the built-in block of the U-groove sliding frame (7) and the inner wall of the spiral groove of the lead screw (12), the force that causes the lead screw (12) to rotate starts to rotate. The lead screw (12) drives the elastic telescopic rod (13) to rotate. During the process that the elastic telescopic rod (13) drives the impact block (14) to rotate, the arc surface of the outer wall of the impact block (14) contacts and impacts the outer wall of the hollow vibration column (15) while generating a resistance force. At this time, the hollow vibration column (15) and the impact block (14) vibrate due to the impact force. Through the transmission of force, the arc-shaped clamping plate (9) drives the arc-shaped rubber pad (10) to vibrate synchronously. At the same time, relying on the arc surface of its own and the arc surface of the hollow vibration column (15), the impact block (14) makes the telescopic end of the elastic telescopic rod (13) contract towards the fixed end, ensuring that the telescopic end of the elastic telescopic rod (13) drives the impact block (14) to be able to cross over the hollow vibration column (15).
