Description

Technical Field

[0001] This invention relates to the field of motor housing manufacturing technology, and in particular to an automatic pressing device for double outer rings of a new energy motor housing. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the demand for new energy motors has increased significantly. As important components of the new energy motor housing, the differential outer ring and counter outer ring need to be precisely pressed into the designated position of the motor housing using an interference fit. In the existing technology, some technicians in related fields have provided technical solutions for the automatic pressing of motor housing components. For example, Chinese patent CN116038294A discloses an automatic pressing device for the outer ring of a transmission tapered bearing. It achieves automatic pressing of the bearing outer ring by using a servo press in conjunction with multiple sets of cylinders, which improves the pressing efficiency to a certain extent. However, it requires the outer ring to be placed on the housing first, or positioned on the housing before placing the outer ring on the housing. Therefore, it cannot automatically place the outer ring, making it difficult to ensure accurate placement. Moreover, it requires frequent machine stops during production to place the outer ring, affecting work efficiency. If the outer ring is placed manually, the operator must enter the core working area of ​​the equipment, making it impossible to separate the operator from the machine and posing a significant safety hazard of mechanical injury.

[0003] In addition, Chinese patent CN118046191A discloses an automatic material handling device for a bearing outer ring press. Although the bearing outer ring can be gripped by a three-jaw structure that moves down and flips, the three-jaw structure only grips the side wall of the bearing outer ring, resulting in the bearing outer ring lacking bottom support. This makes it easy for the bearing outer ring to slip when the three-jaw structure grips the bearing outer ring and flips, thus lacking material handling stability.

[0004] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing outer-ring pressing methods. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automatic pressing device for double outer rings of a new energy motor housing. The device is characterized by comprising: an outer ring feeding mechanism, a housing bearing mechanism, and a material handling mechanism. The outer ring feeding mechanism is used to stack and sequentially supply the outer rings to be taken; The housing support mechanism is used to position and place the motor housing to be press-fitted; The material handling mechanism is used to take material from the outer ring feeding mechanism, transfer the outer ring, and press it into the motor housing; The material handling mechanism is equipped with a gripper unit that can hold the outer ring. The gripper unit has an outer ring lifting mechanism and a telescopic receiving plate. After the gripper unit holds the uppermost outer ring of the outer ring feeding mechanism, the outer ring is lifted upward by the outer ring lifting mechanism, so that a clearance gap is formed between the lifted outer ring and the adjacent outer ring below. The receiving plate can extend into the clearance gap to provide bottom support for the lifted outer ring.

[0006] Preferably, the gripper unit includes a connecting plate, an abutment platform, a clamping plate, and a diameter adjustment assembly for driving the clamping plate to open and close; The connecting plate is installed on the drive output end of the material handling mechanism. The bottom of the connecting plate is fixedly connected to the abutment platform. The inner side of the abutment platform is arranged with a clamping plate that can be opened and closed relative to each other. The abutment platform and the clamping plate together form a clamping end that fits against the outer ring side wall.

[0007] Preferably, a fixing frame is fixedly provided at the lower end of the connecting plate, and the receiving plate is horizontally slidably assembled on the fixing frame; A return spring is provided between the receiving plate and the fixed frame. Under normal conditions, the return spring causes the receiving plate to retract and avoid the outer ring. The connecting plate is equipped with a retractable cylinder and a steel wire rope. The steel wire rope is pulled by the retractable cylinder, and at the same time, the outer ring lifting mechanism is driven to lift and the receiving plate slides radially inward along the outer ring. The stroke difference realizes the action of first lifting to form a clearance gap, and then the receiving plate inserting into the clearance gap.

[0008] Preferably, an installation groove is provided on the inner side of the abutment platform; The outer ring lifting mechanism includes a lifting block that is slidably disposed in the mounting groove. A connecting rod that slides through the abutment platform is installed between the upper end of the lifting block and the output end of the retracting cylinder. A steel wire rope is connected to the bottom of the lifting block. The retractable cylinder drives the lifting block to rise and raise the outer ring, forming a clearance gap; the other end of the steel wire rope is bent outward and connected to an L-shaped receiving plate, which is used to pull the receiving plate inward and slide it into the clearance gap.

[0009] Preferably, the diameter adjustment assembly includes a protrusion disposed on the outer side of the clamping plate, the protrusion having a sliding groove, and a force-bearing block being slidably assembled in the sliding groove; The connecting plate is fixed with a positioning frame and a support frame along the front-to-back direction. The rectangular strip slides through the support frame and is hinged to the force-bearing block. The rectangular strip is threaded with the lead screw. The two lead screws on the same side are connected by a belt drive. One of the lead screws is driven by a drive motor to rotate and drive the clamp to open and close, adapting to outer rings of different outer diameters.

[0010] Preferably, the material handling mechanism further includes an orthogonal movement module, a hydraulic cylinder, and a visual inspection camera; The orthogonal moving module drives the gripper unit to move in the plane, and the hydraulic cylinder drives the gripper unit to lift and lower as a whole to complete the material picking and pressing. The visual inspection camera is installed at the output end of the hydraulic cylinder. The visual inspection camera moves synchronously with the gripper unit to collect images of the outer ring's appearance and placement posture, thereby realizing the identification of outer ring appearance defects and the determination of positive and negative posture.

[0011] Preferably, the outer ring feeding mechanism includes at least two feeding zones. Each feeding zone is provided with a material rod for stacking and mounting the outer ring, a displacement driving unit for moving the material rod, and a lifting and supply unit for lifting and supporting the outer ring. The lower end of the material rod is provided with a clearance structure for the lifting and supply unit to support the bottom of the outer ring.

[0012] Preferably, the displacement driving unit includes a displacement table, and a first material rod and a second material rod for supporting the double outer rings are installed on the upper end of the displacement table to meet the simultaneous feeding of the double outer rings; The lifting and supply unit includes a transverse module. The transverse module has a vertical frame that can be moved and adjusted between two displacement platforms. The vertical frame has a lifting fork that is slidably installed on its side wall to lift the outer rings on the first and second material rods upwards for easy retrieval.

[0013] Preferably, the housing support mechanism includes a housing tray, parallel guide rails, and an electric slide table slidably mounted on the guide rails. The housing tray is mounted on the electric slide table, and the guide rails are provided with an origin stop block for positioning the electric slide table. The electric slide table drives the housing tray to slide back and forth along the guide rail, so that the motor housing switches positions between the loading station and the pressing station.

[0014] Preferably, the attitude adjustment mechanism includes a rotary cylinder, the output end of which is equipped with a third electric slider via an auxiliary block, and the output end of the third electric slider is equipped with a chuck. The third electric slider is installed in pairs on the auxiliary block and drives the jaws to open and close to clamp the outer ring. The rotary cylinder drives the jaws and the clamped outer ring to rotate as a whole through the auxiliary block, thereby correcting the posture of the outer ring.

[0015] In summary, this application includes the following beneficial technical effects: I. This invention uses a lifting fork to lift the double outer rings on the outer walls of the first and second material rods upwards, thereby achieving timely supply of the double outer rings and avoiding the time wasted when picking up the outer rings. Furthermore, the alternating use of the two feeding zones further achieves continuous material supply, thereby improving the overall efficiency of pressing the double outer rings. In addition, by alternating the supply of materials in the two feeding zones, it is possible to effectively achieve separation of man and machine, and significantly reduce the occurrence of safety accidents in production.

[0016] II. This invention uses a gripper unit to pick up the outer ring, during which a visual inspection camera monitors the outer ring in real time and transmits the monitoring images to a controller for comparison and analysis. If the controller analyzes that the outer ring has defects such as deformation or damage, the unqualified outer ring is placed in a recycling box. If the outer ring's posture does not meet the installation requirements, i.e., the upper and lower end faces are inverted, the outer ring is placed in the posture adjustment mechanism for flipping and adjustment. If the outer ring has no appearance defects, it is pressed into the designated position on the motor housing. Thus, the combination of visual inspection, defective product recycling, and outer ring flipping technologies ensures the accuracy of pressing the outer ring into the motor housing, preventing defective products from being pressed into the motor housing and affecting the normal operation of the motor.

[0017] Third, this invention controls the force block to drive the clamping plate to rotate towards one side of the outer ring axis or to rotate outward and open. It can adaptively adjust according to the diameter of the outer ring. After adjustment, the abutment platform and the two clamping plates can abut against the side wall of the outer ring, thereby increasing the contact area between the clamping end and the outer ring, improving the stability when clamping the outer ring, and avoiding the deformation and damage caused by the outer ring falling due to unstable clamping.

[0018] Fourth, the present invention can lift the outer ring upward while clamping it, so that a gap is created between the outer ring and the next outer ring. Then, the receiving plate is controlled to be inserted into the gap to receive the lifted outer ring, so that the outer ring is fixed at the bottom while being clamped and limited, further ensuring the stability during the process of picking up the outer ring.

[0019] Fifth, this invention uses a chuck to grip the inverted outer ring with its upper and lower end faces facing up, and then flips the outer ring 180°. Through monitoring and adjustment technology, the inverted outer ring can be flipped and adjusted in a timely manner, avoiding the adverse effects caused by the inverted outer ring being pressed in.

[0033] The following is in conjunction with the appendix Figures 1-11 The embodiments of the present invention will be described in detail below.

[0034] This application discloses an automatic double outer ring pressing device for a new energy motor housing. It should be noted that this device is mainly used in the process of pressing the differential outer ring 200 and the counter outer ring 300 onto the motor housing 100. Technically, it enables timely supply of the double outer rings, and the alternating use of two feeding zones further ensures continuous material supply. The alternating material supply effectively separates the operator from the machine, significantly reducing the occurrence of safety accidents during production. In particular, when picking up the outer rings, it can monitor them in real time, recycle defective outer rings, and flip and adjust outer rings with inverted upper and lower end faces to ensure the accuracy of pressing the outer rings into the motor housing 100. Furthermore, this automatic double outer ring pressing device can also support and fix the bottom of the outer ring while clamping it, ensuring stability during the outer ring picking process.

[0035] Reference Figure 1 and Figure 2 As shown, an automatic double outer ring pressing device for a new energy motor housing 100 includes a workbench 1, with a housing tray 41 for placing the motor housing 100 on the upper end of the workbench 1, and a housing support mechanism 4 installed between the workbench 1 and the housing tray 41; an outer ring feeding mechanism 2, installed on the upper end of the workbench 1, for supplying the differential outer ring 200 and the counter outer ring 300 to the motor housing 100, and the outer ring feeding mechanism 2 includes a first feed rod 23 and a second feed rod 24 for placing the differential outer ring 200 and the counter outer ring 300.

[0036] Furthermore, it also includes a frame 3, which is set on the upper end of the workbench 1. The frame 3 is set outside the housing tray 41, the housing support mechanism 4 and the outer ring feeding mechanism 2. The frame 3 is equipped with a material picking mechanism 5 for picking up the differential outer ring 200 and the counter outer ring 300.

[0037] Furthermore, it also includes an attitude adjustment mechanism 6, which is set on the frame 3. After the material picking mechanism 5 picks up the differential outer ring 200 or the counter outer ring 300, it checks whether the positions of the two outer rings are correctly placed, and places the incorrectly placed two outer rings at the attitude adjustment mechanism 6. The attitude adjustment mechanism 6 flips and adjusts the two outer rings to ensure that the differential outer ring 200 and the counter outer ring 300 are accurately pressed into the motor housing 100 in the specified posture. The controller (not shown in the figure) is set on the outside of the worktable 1 and is electrically connected to the housing support mechanism 4, the outer ring feeding mechanism 2 and the attitude adjustment mechanism 6. It is used to transmit commands to the housing support mechanism 4, the outer ring feeding mechanism 2 and the attitude adjustment mechanism 6.

[0038] In the specific implementation process, firstly, the differential outer ring 200 and the counter outer ring 300 are placed in designated positions. Then, the controller transmits commands to the housing support mechanism 4, the outer ring feeding mechanism 2, and the attitude adjustment mechanism 6. The housing support mechanism 4 transports the housing tray 41 to the edge of the worktable 1 to facilitate placing the motor housing 100 on the housing tray 41. Next, the housing support mechanism 4 transports the motor housing 100 to the designated position where it is pressed into the differential outer ring 200 and the counter outer ring 300. Then, through the cooperation of the material handling mechanism 5, the gripper unit 51, and the outer ring feeding mechanism 2, the differential outer ring 200 and the counter outer ring 300 are sequentially picked up, and... The differential outer ring 200 and the counter outer ring 300 are visually inspected and rotated and adjusted by the attitude adjustment mechanism 6. Finally, the adjusted differential outer ring 200 and counter outer ring 300 are pressed into the designated positions on the motor housing 100 by the material picking mechanism 5. This enables the automatic picking and pressing of the differential outer ring 200 and counter outer ring 300, which is beneficial to improving processing efficiency. After the double outer rings are pressed in, the housing support mechanism 4 transports the motor housing 100 to the edge of the worktable 1, so that the motor housing 100 after the double outer rings are installed can be removed. The motor housing 100 to be pressed into the double outer rings is then placed on the housing tray 41 for double outer ring installation.

[0039] Reference Figure 2 As shown, in order to facilitate the automatic and accurate delivery of the motor housing 100 to the pressing station, in this embodiment, the housing support mechanism 4 includes a housing tray 41, a guide rail 42 arranged in parallel and installed on the upper end of the workbench 1, and an electric slide table 43 slidably mounted on the guide rail 42. The housing tray 41 is installed on the electric slide table 43. The guide rail 42 is provided with an origin stop block 44 for positioning the electric slide table 43. The electric slide table 43 drives the housing tray 41 to slide back and forth along the guide rail 42, so that the motor housing 100 switches positions between the loading station and the pressing station.

[0040] In the specific implementation process, when the motor housing 100 is placed, the controller transmits a command to the electric slide table 43, causing the electric slide table 43 to move the housing tray 41 to the edge of the workbench 1 to the loading station. After the motor housing 100 is placed, the controller causes the electric slide table 43 and the housing tray 41 to move the motor housing 100 in the opposite direction. During this period, the origin stop block 44 can provide a coordinate reference for the electric slide table 43, ensuring that the electric slide table 43 moves the motor housing 100 accurately to the pressing station, so as to facilitate the precise pressing of the double outer rings.

[0041] Reference Figure 3 and Figure 4As shown, in order to continuously supply the differential outer ring 200 and the counter outer ring 300, and to achieve continuous pressing of the double outer rings of the motor housing 100, the outer ring feeding mechanism 2 in this embodiment includes at least two feeding zones. Each feeding zone is equipped with a sliding displacement table 22. The upper end of the displacement table 22 is equipped with a first material rod 23 and a second material rod 24 that support the double outer rings, to meet the simultaneous feeding of the double outer rings. The upper end of the worktable 1 is also equipped with two servo cylinders 25 that drive the displacement table 22 to move. The outer ring feeding mechanism 2 also includes a transverse module 26. The transverse module 26 has a vertical frame 27 that slides and adjusts between the two displacement tables 22 on its side wall. The side wall of the vertical frame 27 has a first electric slider (not shown in the figure) that is electrically connected to the controller. The side wall of the first electric slider is equipped with a lifting fork 29, which lifts the outer rings on the first material rod 23 and the second material rod 24 upwards for easy handling. In the initial state... Below, the first material rod 23 and the second material rod 24 are respectively located at the opening of the lifting fork 29 corresponding to their positions, and the differential outer ring 200 and the counter outer ring 300 at the upper end of the first material rod 23 and the second material rod 24 are stacked on the upper end of the lifting fork 29. Two infrared detectors 20 for monitoring the lifting height of the double outer rings are provided on the frame 3. The infrared detectors 20 are electrically connected to the controller. It should be noted that a circular block 231 is installed at the lower end of the first material rod 23 and the second material rod 24. Two planar clearance grooves 232 are opened on the outer wall of the circular block 231. When the double outer rings are fitted on the outer wall of the first material rod 23 and the second material rod 24, the double outer rings can be placed on the circular block 231, while the outer side of the double outer rings is exposed outside the planar clearance grooves 232. Therefore, the circular block 231 can not only lift the stacked double outer rings upward, but also allow the lifting fork 29 to smoothly insert into the planar clearance grooves 232, ensuring that the lifting fork 29 lifts the double outer rings from the bottom upward.

[0042] In the specific implementation process, the controller first transmits a command to the servo cylinder 25, causing the servo cylinder 25 to drive the displacement table 22, the positioning plate 21, the first material rod 23 and the second material rod 24 to move as a whole towards the edge of the worktable 1, so that the double outer rings can be stacked outside the first material rod 23 and the second material rod 24. Then, the servo cylinder 25 drives the displacement table 22 to move in the opposite direction and reset. At this time, the lifting fork 29 is in the lowest position, so the first material rod 23 and the second material rod 24 are smoothly moved to the opening of the lifting fork 29, and the double outer rings stacked on the outer wall of the first material rod 23 and the second material rod 24 are both located above the lifting fork 29.

[0043] Infrared detector 20 monitors the height of the double outer rings on the outer walls of the first material rod 23 and the second material rod 24 in real time, and transmits the monitoring information to the controller for real-time analysis. When the differential outer ring 200 or the counter outer ring 300 is picked up by the material picking mechanism 5, infrared detector 20 detects that the height of the differential outer ring 200 or the counter outer ring 300 has decreased. At this time, the controller transmits a command to the first electric slider corresponding to the outer ring. The first electric slider drives the outer ring to move upward through the lifting fork 29, so as to realize the timely supply of the double outer rings and avoid wasting time when picking up the outer rings.

[0044] In addition, the two feeding zones can be used alternately. After the double outer rings in one feeding zone are retrieved, the controller transmits a command to the servo cylinder 25 of that feeding zone. The servo cylinder 25 drives the displacement table 22, the first material rod 23, and the second material rod 24 to retract from the lifting fork 29. Then, the controller transmits a command to the lateral movement module 26, causing the lateral movement module 26 to move the lifting fork 29 horizontally to the other feeding zone. Subsequently, the controller causes the servo cylinder 25 of the other feeding zone to move the first material rod 23 and the second material rod 24, which are fully loaded with the double outer rings, to the opening of the lifting fork 29. This further realizes the continuous supply of materials, thereby improving the overall efficiency of pressing the double outer rings. In addition, by alternating the supply of materials between the two feeding zones, the separation of man and machine can be effectively realized, greatly reducing the occurrence of safety accidents in production.

[0045] Reference Figure 5 As shown, in order to facilitate the precise placement of the double outer rings at the designated position on the motor housing 100, a corresponding material handling mechanism 5 is also provided in this embodiment. Specifically, the material handling mechanism 5 also includes an orthogonal moving module 53 installed on the upper end of the frame 3. A lowering column 56 is installed on the orthogonal moving module 53, and a hydraulic cylinder 54 is installed on the lowering column 56. A linkage block 57 is provided at the bottom of the telescopic end of the hydraulic cylinder 54. Two moving plates 59 are slidably arranged at the lower end of the linkage block 57 through the second electric slider 58. A gripper unit 51 is provided at the lower end of the moving plate 59 through the extension rod 591, and a vision inspection camera 55 is installed on the linkage block 57 through the positioning strip. The orthogonal moving module 53, the hydraulic cylinder 54, the second electric slider 58 and the vision inspection camera 55 are all electrically connected to the controller. A recycling box 50 for holding defective products is also provided on the frame 3.

[0046] In the specific implementation process, the controller transmits instructions to the orthogonal movement module 53, which drives the lowering column 56, hydraulic cylinder 54, linkage block 57 and gripper unit 51 to move as a whole to above the outer ring 200 of the differential or the outer ring 300 of the counter to be picked up, so that the axis of the gripper unit 51 coincides with the axis of the corresponding outer ring. Then the controller transmits instructions to the hydraulic cylinder 54, which drives the linkage block 57 and gripper unit 51 to move down to the uppermost outer ring. Then the controller transmits instructions to the second electric slider 58, which drives the two gripper units 51 to move closer to each other and abut against the side wall of the outer ring through the extension rod 591 to grip the corresponding outer ring. Then the hydraulic cylinder 54 drives the linkage block 57, gripper unit 51 and the gripped outer ring to move up.

[0047] During this period, the visual inspection camera 55 captures images of the outer ring's appearance and placement posture, enabling the identification of defects in the outer ring's appearance and the determination of its forward and reverse posture. The monitoring images are then transmitted to the controller for comparative analysis. If the controller analyzes that the outer ring has defects such as deformation or damage, the controller drives the lowering column 56 to move above the recycling box 50 via the orthogonal movement module 53. Then, the second electric slider 58 drives the gripper unit 51 to move away from each other, which is used to put the unqualified outer ring into the recycling box 50. If the posture of the gripped outer ring does not meet the installation requirements, i.e., the upper and lower end faces are inverted, the controller drives the lowering column 56 to move to the posture adjustment mechanism 6 via the orthogonal movement module 53, so as to flip and adjust the outer ring to ensure that the outer ring is pressed into the motor housing 100 according to the specified requirements, preventing improper installation from affecting the motor performance.

[0048] If the outer ring being gripped has no visible defects, the controller drives the lowering column 56 to move above the corresponding installation position on the motor housing 100 via the orthogonal movement module 53. Then, the hydraulic cylinder 54 drives the linkage block 57, the gripper unit 51, and the outer ring to move downwards as a whole, pressing the outer ring into the designated position on the motor housing 100. Then, the second electric slider 58 moves the two gripper units 51 away from each other, releasing the gripping effect on the outer ring. Repeating the above steps will press the differential outer ring 200 and the counter outer ring 300 into the motor housing 100 in sequence. Thus, through the combination of visual inspection, defective product recycling, and outer ring flipping techniques, the accuracy of pressing the outer ring into the motor housing 100 can be guaranteed, avoiding defective products from being pressed into the motor housing 100 and affecting the normal operation of the motor.

[0049] In addition, the controller can drive the lowering column 56 to move to different feeding areas to pick up the outer ring through the orthogonal movement module 53, thereby adaptively adjusting according to the feeding area that can provide materials.

[0050] Reference Figure 6 and Figure 7As shown, since different models of differential outer ring 200 and counter outer ring 300 need to be installed on different models of motor housing 100, the diameters of the double outer rings of different models are different. In order to stably pick up double outer rings of different diameters, in this embodiment, the gripper unit 51 includes a connecting plate 511 installed at the lower end of the extension rod 591. The two connecting plates 511 are provided with abutment platforms 512 on opposite sides. Two clamping plates 513 are symmetrically rotatably installed on the outer wall of the abutment platform 512. The abutment platform 512 and the two clamping plates 513 constitute a gripping end that abuts against the side wall of the outer ring. The gripper unit 51 also includes a diameter adjustment component 514 for driving the clamping plates 513 to open and close.

[0051] Furthermore, the diameter adjustment assembly 514 includes a protrusion 522 disposed on the side of the clamping plate 513 away from its clamping outer ring. A sliding groove 523 is formed on the protrusion 522, and a force-bearing block 524 is slidably disposed within the sliding groove 523. Two sets of support members corresponding to the positions of the protrusion 522 are disposed at the lower end of the connecting plate 511. The support members include a positioning frame 525 and a support frame 526. A rectangular strip 527 is slidably passed through the support frame 526. The rectangular strip 527 is hinged to the force-bearing block 524. The side of the rectangular strip 527 away from the force-bearing block 524 is connected via... A lead screw 528 is threaded through the positioning frame 525. When the lead screw 528 rotates, it applies a driving force to the rectangular bar 527. The rectangular bar 527 cannot rotate under the action of the support frame 526. Therefore, the rectangular bar 527 moves along the axis of the lead screw 528. The two lead screws 528 on the same connecting plate 511 are connected by belt drive. A drive motor 529 connected to the lead screw 528 is installed on any positioning frame 525 through a motor base. The drive motor 529 is electrically connected to the controller.

[0052] In practical implementation, when it is necessary to replace different models of motor housing 100, differential outer ring 200, and counter outer ring 300, the controller transmits a command to the drive motor 529, causing the drive motor 529 to drive the lead screw 528 to rotate. The lead screw 528 drives the rectangular bar 527 to move along its axis. While the rectangular bar 527 moves, it drives the clamping plate 513 to rotate towards one side of the outer ring axis or rotate outward through the force block 524, which can adaptively adjust according to the diameter of the outer ring. During this process, the force block 524 adaptively moves within the sliding groove 523. Sliding avoids interference, so the adjusted abutment platform 512 and the two clamping plates 513 can abut against the side wall of the outer ring, thereby increasing the contact area between the clamping end and the outer ring, improving the stability when clamping the outer ring, and avoiding defects such as deformation and damage caused by unstable clamping leading to the outer ring falling off; pressure plates are installed on opposite sides of the two abutment platforms 512, so after the outer ring is placed in the designated position of the motor housing 100, the gripper unit 51 continues to move down, thereby pressing the outer ring smoothly into the motor housing 100 in an interference fit through the pressure plates.

[0053] Reference Figure 8 As shown in the figure, in order to further ensure the stability when clamping the outer ring, in this embodiment, a fixing frame 518 is installed at the lower end of the connecting plate 511, and a receiving plate 52 is slidably arranged at the lower end of the fixing frame 518. A return spring 519 is installed between the side of the receiving plate 52 away from the abutment platform 512 and the fixing frame 518. The return spring 519 always applies a driving force to the receiving plate 52 in the direction away from the abutment platform 512, so that the receiving plate 52 retracts to the bottom of the abutment platform 512 in the initial state (shown in Figure 8).

[0054] Furthermore, in this embodiment, a mounting post is provided at the upper end of the connecting plate 511, and a retractable cylinder 520 electrically connected to the controller is provided on the side wall of the mounting post. A mounting groove 515 is provided in the middle of the side of the abutment platform 512 away from the connecting plate 511. A lifting block 516 is slidably provided inside the mounting groove 515. Under the limiting action of the mounting groove 515, the lifting block 516 can only slide up and down and cannot move in other directions. An elastic rubber pad is provided on the contact surface between the lifting block 516 and the outer ring. The elastic rubber pad can increase the friction between the lifting block 516 and the outer ring. The bottom of the telescopic end of the retractable cylinder 520 is fixedly connected to the lifting block 516 through a connecting rod 517. A steel wire rope 521 is installed between the lower end of the lifting block 516 and the receiving plate 52. A guide wheel is rotatably installed inside the abutment platform 512, which abuts against the bend of the steel wire rope 521 to prevent the bend of the steel wire rope 521 from being worn.

[0055] In the specific implementation process, when the outer ring is taken from the first material rod 23 and the second material rod 24, the abutment platform 512 and the clamping plate 513 abut against the side wall of the outer ring, and the elastic rubber pad on the side wall of the lifting block 516 abuts against the side wall of the outer ring. The controller transmits a command to the retraction cylinder 520, and the telescopic end of the retraction cylinder 520 retracts and drives the connecting rod 517, the lifting block 516, the elastic rubber pad and the outer ring to move upward as a whole. The upward movement distance of the outer ring is the distance between the lifting block 516 and the inner top wall of the mounting groove 515. At the same time, the lifting block 516 applies tension to the wire rope 521, and the wire rope 521 drives the receiving plate 52 to move towards the side closer to the outer ring. However, the receiving plate 52 does not pass the abutment platform 512 at the first moment. That is, when the outer ring is lifted upward, the receiving plate 52 has not yet inserted into the gap to avoid the receiving plate 52 abutting against the side wall of the outer ring and causing interference.

[0056] After the lifting block 516 raises the outer ring upwards, a gap is created between the outer ring and the next outer ring. Then, the retracting cylinder 520 continues to pull the steel wire rope 521 through the connecting rod 517 and the lifting block 516. After the lifting block 516 moves up to its limit position, it can no longer move up. At the same time, the steel wire rope 521 pulls the receiving plate 52 to insert into the gap between the two outer rings to receive the raised outer ring. This allows the outer ring to be fixed at the bottom while being clamped and limited, further ensuring the stability during the process of picking up the outer ring.

[0057] When the outer ring needs to be pressed into the motor housing 100, the telescopic end of the retraction cylinder 520 extends and drives the lifting block 516 to move down and reset via the connecting rod 517. The receiving plate 52 resets under the action of the reset spring 519 and stretches the wire rope 521 to reset, which is used to release the bottom receiving limit of the outer ring. Then the hydraulic cylinder 54 drives the extension rod 591 and the clamping plate 513 to move down, which is used to press the outer ring into the motor housing 100.

[0058] Reference Figure 10 and Figure 11 As shown, in order to facilitate the flipping and adjustment of the outer ring with its upper and lower end faces inverted, in this embodiment, the attitude adjustment mechanism 6 includes a positioning column 65 installed on the upper end of the worktable 1. A rotary cylinder 61 is provided on one side of the positioning column 65 via a mounting platform 66. An auxiliary block 62 is provided on the output shaft of the rotary cylinder 61. Two third electric sliders 63 are symmetrically arranged on the side of the auxiliary block 62 away from the rotary cylinder 61. The rotary cylinder 61 and the third electric sliders 63 are both electrically connected to the controller. A pawl 64 is installed on the side of the third electric slider 63 away from the auxiliary block 62. Baffles 67 are provided at both the upper and lower ends of the pawl 64, forming horizontal rolled edges at the upper and lower ends of the pawl 64. When the pawl 64 abuts against the side wall of the outer ring, the baffles 67 are located at the upper and lower ends of the outer ring to limit the outer ring and prevent it from falling off due to lack of limit when flipping the outer ring.

[0059] In the specific implementation process, the controller analyzes the monitoring image of the visual inspection camera 55. If the upper and lower end faces of the outer ring are inverted, the orthogonal movement module 53 moves the outer ring above the jaw 64. Then, the hydraulic cylinder 54 drives the jaw unit 51 and the outer ring to move down to the same height as the jaw 64. Next, the controller transmits a command to the third electric slider 63, causing the third electric slider 63 to drive the jaw 64 to clamp the outer ring. Then, the hydraulic cylinder 54 drives the jaw unit 51 to move up to outside the rotation range of the jaw 64. Then, the controller transmits a command to the rotary cylinder 61, causing the rotary cylinder 61 to drive the jaw 64 and the outer ring to rotate 180° to flip and adjust the inverted outer ring. Then, the hydraulic cylinder 54 drives the jaw unit 51 to move down to clamp the adjusted outer ring and press the outer ring into the designated position of the motor housing 100. Thus, through the technical cooperation of monitoring and adjustment, the inverted outer ring can be flipped and adjusted in time, avoiding adverse effects caused by the inverted outer ring being pressed in.

[0060] During operation: First, the outer ring 200 of the differential and the outer ring 300 of the counter are stacked on the outer walls of the first material bar 23 and the second material bar 24. The double outer rings of the outer walls of the first material bar 23 and the second material bar 24 are both located above the lifting fork 29. Next, the electric slide 43 drives the housing tray 41 to move towards the edge of the worktable 1 to facilitate the placement of the motor housing 100. Then, the controller causes the electric slide 43 and the housing tray 41 to drive the motor housing 100 to move in the opposite direction to the designated position.

[0061] The orthogonal movement module 53 moves the lowering column 56, hydraulic cylinder 54, linkage block 57, and gripper unit 51 together to above the outer ring 200 of the differential or the outer ring 300 of the counter to be retrieved. Then, the hydraulic cylinder 54 moves the linkage block 57 and gripper unit 51 down to the uppermost outer ring. Next, the controller transmits a command to the second electric slider 58, causing the second electric slider 58 to move the two gripper units 51 closer together via the extension rod 591, so that the abutment platform 512 and the clamping plate 513 abut against the side wall of the outer ring, and the lifting block 516 moves to the side... The elastic pad of the wall abuts against the side wall of the outer ring. Then, the telescopic end of the retraction cylinder 520 retracts and drives the connecting rod 517, the lifting block 516, the elastic pad and the outer ring to move upward as a whole. A gap is created between the outer ring and the next outer ring. At the same time, the wire rope 521 pulls the receiving plate 52 to one side of the outer ring and inserts it into the gap to receive the raised outer ring. This allows the outer ring to be fixed at the bottom while being clamped and limited. Then, the hydraulic cylinder 54 drives the linkage block 57, the gripper unit 51 and the gripped outer ring to move upward.

[0062] After the outer ring is clamped, the visual inspection camera 55 monitors the outer ring in real time and transmits the monitoring image to the controller for comparison and analysis. If the controller analyzes that the outer ring has defects such as deformation or damage, the orthogonal movement module 53 drives the lowering column 56 to move above the recycling box 50, so that the unqualified outer ring can be put into the recycling box 50.

[0063] If the upper and lower ends of the outer ring are inverted, the controller drives the lowering column 56 to move above the jaw 64 via the orthogonal movement module 53. Then, the hydraulic cylinder 54 drives the jaw unit 51 and the outer ring to move down to the same height as the jaw 64. Next, the jaw 64 grips the outer ring. The hydraulic cylinder 54 drives the jaw unit 51 to move up to outside the rotation range of the jaw 64. The rotary cylinder 61 drives the jaw 64 and the outer ring to rotate 180°. Then, the hydraulic cylinder 54 drives the jaw unit 51 to move down to grip the adjusted outer ring and press the outer ring into the designated position of the motor housing 100. Through the technical cooperation of monitoring and adjustment, the inverted outer ring can be flipped and adjusted in time to avoid adverse effects caused by the inverted outer ring being pressed in.

[0064] If the outer ring gripped by the gripper unit 51 has no appearance defects, the orthogonal movement module 53 drives the lowering column 56 to move above the corresponding installation position on the motor housing 100. Then, the hydraulic cylinder 54 drives the linkage block 57, the gripper unit 51 and the outer ring to move down as a whole. The gripper unit 51 drives the pressure plate to move down and presses the outer ring into the motor housing 100 smoothly with an interference fit. Repeating the above steps will press the differential outer ring 200 and the counter outer ring 300 into the motor housing 100 in sequence.
