Description

Technical Field

[0001] This utility model relates to the field of motor equipment technology, and more specifically, to a quick press-fitting device for the housing of an automotive swing door motor. Background Technology

[0002] As the core drive component of the automotive electric door system, the automotive swing door motor typically consists of an integrally molded shaft mounting part and a motor mounting part. The top of the shaft mounting part has a first recess with a vertical opening, and a first shaft hole for assembling the shaft system is coaxially arranged inside it. The laterally extending motor mounting part has a second recess with a horizontal opening, and a second shaft hole that cooperates with the transmission mechanism is provided inside the cavity.

[0003] In the existing production process, the bearing press-fitting operation needs to be carried out in steps: the operator must first place the housing on the pressure base, fix the top hole of the rotating shaft mounting part facing upward, manually place the first bearing into the first shaft hole, and then use a press to complete the bearing press-fitting in the first shaft hole; then the fixation needs to be released and the housing position readjusted, fix the side hole of the motor mounting part facing upward, and then manually place the second bearing again and press-fit the bearing into the second shaft hole.

[0004] This traditional operating mode has significant drawbacks: First, the housing requires repeated positioning and clamping during the two pressing processes, which not only wastes time but also easily affects assembly accuracy due to positioning errors. Second, the manual placement of bearings has an efficiency bottleneck and is difficult to match the pace of modern production. Third, existing general-purpose pressing equipment lacks specialized tooling for multi-directional pressing of irregularly shaped housings, making it impossible to achieve synchronous operation at two workstations. These technical shortcomings directly restrict production efficiency and product consistency. Especially in mass production scenarios, the quality fluctuations and time losses caused by manual intervention are more prominent, necessitating the development of specialized equipment with multi-directional synchronous pressing capabilities to overcome existing technical bottlenecks. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the prior art and provide a rapid pressing equipment for automotive swing door motor housings that can achieve synchronous and rapid pressing of bearings in the top and side holes of the motor housing, automated feeding, and positioning.

[0006] To address the aforementioned problems, this utility model provides a rapid pressing device for automotive swing door motor housings, comprising a worktable and a pressure-bearing base fixed to the top of the worktable. The pressure-bearing base is equipped with a locking mechanism. The worktable also includes a top hole pressing mechanism, a side hole pressing mechanism, a first bearing supply mechanism, a second bearing supply mechanism, and a feeding mechanism. A portal frame with both ends fixed to the worktable spans directly above the pressure-bearing base. The top hole pressing mechanism includes a first pressing head that is vertically mounted on the portal frame, and a mechanism fixed to the portal frame for driving the first pressing head to move horizontally between the first bearing supply mechanism and the pressure-bearing base. The device includes a translational drive and a lifting drive fixed to the output end of the translational drive for driving the first pressure head to move up and down directly above the pressure base. The end of the first pressure head is magnetic and used to magnetically attract the first bearing of the first bearing supply mechanism. The side hole pressing mechanism includes a second pressure head located on the side of the pressure base and a translational drive for driving the second pressure head to move closer to or away from the pressure base. The feeding mechanism is located between the second bearing supply mechanism and the second pressure head, and its execution end is provided with a gripper assembly. The gripper assembly is used to grip the second bearing of the second bearing supply mechanism and transfer it to the second pressure head.

[0007] Compared with existing technologies, this invention has the following advantages: By coordinating the top-hole pressing mechanism and the side-hole pressing mechanism, and in conjunction with the automated feeding system of the first bearing supply mechanism, the second bearing supply mechanism, and the feeding mechanism, this invention achieves synchronous pressing of dual-hole bearings on the motor housing. Specifically, the first pressing head, through magnetic adsorption and the cooperation of a translational drive component, precisely grips the first bearing and completes vertical pressing; the side-hole pressing mechanism, through the translational drive mechanism, pushes the second pressing head horizontally, and combined with the bearing transfer function of the feeding mechanism's gripper assembly, achieves automatic positioning and pressing of the lateral bearing. This dual-station synchronous operation mode eliminates the need for repetitive housing positioning, and the entire equipment achieves full automation of the bearing pressing process, effectively solving the technical problems of low efficiency and high reliance on manual labor in traditional operations.

[0008] As an improvement, the end of the first pressure head radially contracts to form a first coaxial positioning boss, and the end of the second pressure head radially contracts to form a second coaxial positioning boss. With this structure, the radial contraction of the first and second coaxial positioning bosses creates a clearance fit with the bearing's inner bore during press-fitting, ensuring rapid alignment and positioning of the pressure head and bearing. The self-centering function is achieved by utilizing the tolerance fit between the outer diameter of the boss and the inner bore of the bearing, significantly improving the coaxiality accuracy of the press-fitting process.

[0009] Specifically, the first bearing supply mechanism includes a first vibratory feeder for storing and conveying the first bearing, and a first support located at the end of the conveying track of the first vibratory feeder. The first support is fixed to the workbench and located on one side of the pressure base, below the horizontal movement path of the first pressure head. The top edge of the first support has a semi-circular first limiting groove with an opening facing the end of the conveying track. The first limiting groove is used to receive and position the first bearing for magnetic pickup by the first pressure head. With this structure, the first vibratory feeder achieves automatic posture correction of the first bearing through directional vibration. Combined with the circumferential constraint of the bearing's outer circle by the semi-circular first limiting groove, it ensures that the first bearing stops at the pickup station in a predetermined posture. The magnetic pressure head can achieve precise adsorption by vertically moving downwards, solving the posture error problem when manually placing bearings and realizing automated continuous feeding of bearings in the vertical direction.

[0010] Specifically, the translation drive mechanism includes a support rail extending outward from the other side of the pressure base, a slide movably mounted on the support rail, and front and rear drive cylinders that drive the slide to slide back and forth. The support rail is fixed to the worktable, and the front and rear drive cylinders are fixed to the worktable and located at the extended end of the support rail. The output end of the front and rear drive cylinders is fixedly connected to one end of the slide, and the second pressure head is fixed to the other end of the slide and faces the pressure base. With this structure, the sliding fit between the support rail and the slide provides a highly rigid horizontal movement guide for the second pressure head. The front and rear drive cylinders drive the slide to precise positioning via a linear push-pull method. The design of the cylinder fixed at the extended end of the support rail optimizes the torque transmission path, effectively reducing mechanism deformation during the pressing process and ensuring the straightness accuracy of the lateral pressing feed.

[0011] Specifically, the second bearing supply mechanism includes a second vibratory feeder for storing and transporting the second bearing, a second support fixed to the worktable, and an extension seat fixed to the front end of the second support and extending to the end of the conveying track of the second vibratory feeder. The top edge of the extension seat has a semi-circular second limiting groove with an opening facing the end of the conveying track. The bottom of the second limiting groove has a through hole with a diameter larger than the central shaft hole of the second bearing but smaller than the outer diameter of the second bearing. Below the extension seat is a lifting cylinder fixed to the second support. A push rod, its lower end fixed to the piston rod of the lifting cylinder, passes through the through hole. The lifting cylinder drives the push rod to move upward, lifting the second bearing, which is positioned in the second limiting groove. With this structure, the combination of the second limiting groove and the through hole in the extension seat achieves temporary positioning and lifting separation of the second bearing. After the lifting cylinder vertically lifts the bearing using the push rod, it is freed from the constraint of the limiting groove, creating unobstructed space for the gripper assembly to grasp it. The diameter difference design ensures effective support of the bearing by the push rod while preventing the bearing from slipping during lifting, achieving precise separation and transfer of the bearing in the horizontal direction.

[0012] As an improvement, a slider-rail assembly is provided between the extension seat and the lifting cylinder. The slide rail of the slider-rail assembly is vertically fixed to the second support. The upper end of the slider of the slider-rail assembly is fixed to the lower end of the push rod, and the lower end of the slider of the slider-rail assembly is fixed to the piston rod of the lifting cylinder. With this structure, the slider-rail assembly provides rigid vertical guidance for the lifting movement. The precise fit between the slide rail and the slider eliminates radial offset during the lifting process of the push rod, ensuring that the axis of the push rod always remains coaxial with the through hole. At the same time, the radial load of the piston rod of the lifting cylinder is transferred to the slide rail, extending the service life of the cylinder.

[0013] Specifically, the feeding mechanism includes a horizontal frame that spans across the support rail and is vertically fixed to the worktable at both ends, a horizontal drive linear module that is horizontally fixed to the horizontal frame, a vertical drive linear module that is vertically fixed to the movable block of the horizontal drive linear module, and a rotary cylinder that is fixed to the lifting block of the vertical drive linear module. The gripper assembly is fixed to the rotary output end of the rotary cylinder. The horizontal frame extends from the support rail toward the second support. The horizontal drive linear module drives the vertical drive linear module to move horizontally along the horizontal frame, and the vertical drive linear module drives the rotary cylinder to move vertically. When the rotary cylinder picks up the second bearing, it drives the gripper assembly to align coaxially with the second limiting groove and the through hole. When placing the bearing, it drives the gripper assembly to align coaxially with the second coaxial positioning boss of the second pressure head. After applying this structure, the combination of the horizontal drive linear module and the vertical drive linear module realizes the three-dimensional spatial precise positioning of the gripper assembly. The rotary cylinder adjusts the end posture to make the gripper assembly coaxially aligned with the second limit groove when picking up and coaxially aligned with the second pressure head when placing. The closed-loop control of the dual linear modules, combined with rotation angle compensation, ensures the spatial orientation accuracy of the bearing during the transfer process and solves the alignment deviation problem when manually transferring the bearing.

[0014] Specifically, the locking and fixing mechanism includes a first contour positioning groove and a second contour positioning groove that are spaced apart vertically and horizontally offset on the pressure-bearing base. The shape of the first contour positioning groove matches the contour of the shaft mounting part of the motor housing, and the shape of the second contour positioning groove matches the contour of the motor mounting part of the motor housing. A placement step is formed between the first and second contour positioning grooves to accommodate the connection between the shaft mounting part and the motor mounting part. With this structure, the vertically offset first and second contour positioning grooves form surface contact constraints with the irregular contours of the shaft mounting part and the motor mounting part of the housing, respectively, preventing the housing from shifting on the pressure-bearing base during press-fitting and ensuring press-fitting accuracy.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 7As shown, a rapid pressing device for automotive swing door motor housing includes a worktable 1 and a pressure-bearing base 2 fixed to the top of the worktable 1. The pressure-bearing base 2 is provided with a locking and fixing mechanism. The worktable 1 is also provided with a top hole pressing mechanism 3, a side hole pressing mechanism 4, a first bearing supply mechanism 5, a second bearing supply mechanism 6, and a feeding mechanism 7. A portal frame 11 with both ends fixed to the worktable 1 is spanned directly above the pressure-bearing base 2. The top hole pressing mechanism 3 includes a first pressing head 31 that is lifted and lowered on the portal frame 11, a translation drive component 32 fixed on the portal frame 11 for driving the first pressing head 31 to move horizontally between the first bearing supply mechanism 5 and the pressure-bearing base 2, and an output end fixed to the translation drive component 32 for driving. The first pressure head 31 is a lifting drive 33 that moves up and down directly above the pressure base 2. The translation drive 32 and the lifting drive 33 are usually cylinders, oil cylinders, electric cylinders or other drive components with linear output function. The end of the first pressure head 31 is magnetic and used to magnetically attract the first bearing of the first bearing supply mechanism 5. The side hole pressing mechanism 4 includes a second pressure head 42 located on the side of the pressure base 2 and a translation drive mechanism 41 for driving the second pressure head 42 to approach or move away from the pressure base 2. The feeding mechanism 7 is located between the second bearing supply mechanism 6 and the second pressure head 42 and its execution end is provided with a gripper assembly 71. The gripper assembly 71 is used to grip the second bearing of the second bearing supply mechanism 6 and transfer it to the second pressure head 42.

[0027] This embodiment achieves synchronous pressing of dual-hole bearings in motor housings through the coordinated layout of the top hole pressing mechanism 3 and the side hole pressing mechanism 4, along with the automated feeding system of the first bearing supply mechanism 5, the second bearing supply mechanism 6, and the feeding mechanism 7. Specifically, the first pressing head 31, through magnetic adsorption and the cooperation of the translational drive component 32, precisely grips the first bearing and completes vertical pressing; the side hole pressing mechanism 4, through the translational drive mechanism 41, pushes the second pressing head 42 horizontally, and combined with the bearing transfer function of the gripper assembly 71 of the feeding mechanism 7, achieves automatic positioning and pressing of the lateral bearings. The dual-station synchronous operation mode eliminates the need for repetitive housing positioning, and the entire equipment achieves full automation of the bearing pressing process, effectively solving the technical problems of low efficiency and high reliance on manual labor in traditional operations.

[0028] like Figure 3 and Figure 7 As shown, the end of the first pressure head 31 radially contracts to form a first coaxial positioning boss 310, and the end of the second pressure head 42 radially contracts to form a second coaxial positioning boss 420. With this structure, the radial contraction of the first coaxial positioning boss 310 and the second coaxial positioning boss 420 creates a clearance fit with the bearing inner hole during press-fitting, ensuring rapid alignment and positioning of the pressure head and bearing. The self-centering function is achieved by utilizing the tolerance fit between the outer diameter of the boss and the inner hole of the bearing, significantly improving the coaxiality accuracy of the press-fitting.

[0029] like Figure 2 and Figure 3 As shown, the first bearing supply mechanism 5 includes a first vibratory feeder 51 for storing and conveying the first bearing, and a first support 52 disposed at the end of the conveying track of the first vibratory feeder 51. The first support 52 is fixed on the workbench 1 and located on one side of the pressure base 2, and below the horizontal movement path of the first pressure head 31. The top edge of the first support 52 has a semi-circular first limiting groove 520 with an opening facing the end of the conveying track. The first limiting groove 520 is used to receive and position the first bearing for magnetic pickup by the first pressure head 31. With this structure, the first vibratory feeder 51 achieves automatic posture correction of the first bearing through directional vibration. Combined with the circumferential constraint of the bearing's outer circle by the semi-circular first limiting groove 520, it ensures that the first bearing stops at the pickup station in a predetermined posture. The magnetic pressure head can achieve precise adsorption by vertically moving downward, solving the posture error problem when manually placing bearings and realizing automated continuous feeding of bearings in the vertical direction.

[0030] like Figure 4 and Figure 6 As shown, the translation drive mechanism 41 includes a support rail 411 extending outward from the other side of the pressure base 2, a slide 412 movably mounted on the support rail 411, and a front and rear drive cylinder 413 that drives the slide 412 to slide back and forth. The support rail 411 is fixed to the worktable 1, and the front and rear drive cylinder 413 is fixed to the worktable 1 and located at the extended end of the support rail 411. The output end of the front and rear drive cylinder 413 is fixedly connected to one end of the slide 412, and the second pressure head 42 is fixed to the other end of the slide 412 and faces the pressure base 2. With this structure, the sliding fit between the support rail 411 and the slide 412 provides a highly rigid horizontal movement guide for the second pressure head 42. The front and rear drive cylinder 413 drives the slide 412 to be precisely positioned by a linear push-pull method. The design of fixing the cylinder at the extended end of the support rail 411 optimizes the torque transmission path, effectively reduces the deformation of the mechanism during the pressing process, and ensures the straightness accuracy of the lateral pressing feed.

[0031] like Figure 6 and Figure 7As shown, the second bearing supply mechanism 6 includes a second vibratory plate 61 for storing and conveying the second bearing, a second support 62 fixed on the worktable 1, and an extension seat 63 fixed to the front end of the second support 62 and extending to the end of the conveying track of the second vibratory plate 61. The top edge of the extension seat 63 is provided with a semi-circular second limiting groove 630 with an opening facing the end of the conveying track. The bottom of the second limiting groove 630 is provided with a through hole 631 with a diameter larger than the central shaft hole of the second bearing and smaller than the outer diameter of the second bearing. Below the extension seat 63 is a lifting cylinder 64 fixed on the second support 62. A push rod 65 with its lower end fixed on the piston rod of the lifting cylinder 64 is inserted into the through hole 631. The lifting cylinder 64 is used to drive the push rod 65 to move upward and lift the second bearing that is placed in the second limiting groove 630 upward. After applying this structure, the combination of the second limiting groove 630 and the through hole 631 of the extension seat 63 realizes the temporary positioning and lifting separation of the second bearing. The lifting cylinder 64 lifts the bearing vertically through the push rod 65 and then breaks away from the constraint of the limiting groove, creating an unobstructed space for the gripper assembly 71 to grasp. The diameter difference design not only ensures the effective support of the push rod 65 for the bearing, but also avoids the bearing slipping during the lifting process, realizing the precise separation and transfer of the bearing in the horizontal direction.

[0032] like Figure 7 As shown, a slider-rail assembly 66 is provided between the extension seat 63 and the lifting cylinder 64. The slide rail of the slider-rail assembly 66 is vertically fixed on the second support 62. The upper end of the slider of the slider-rail assembly 66 is fixed to the lower end of the push rod 65, and the lower end of the slider of the slider-rail assembly 66 is fixed to the piston rod of the lifting cylinder 64. With this structure, the slider-rail assembly 66 provides a rigid vertical guide for the lifting movement. The precise fit between the slide rail and the slider eliminates the radial offset of the push rod 65 during the lifting process, ensuring that the axis of the push rod 65 remains coaxial with the through hole 631. At the same time, the radial load of the piston rod of the lifting cylinder 64 is transferred to the slide rail, extending the service life of the cylinder.

[0033] like Figure 4 and Figure 5As shown, the feeding mechanism 7 includes a crossbeam 72 that spans horizontally above the support rail 411 and is vertically fixed at both ends to the worktable 1; a horizontally fixed horizontal drive linear module 73; a vertically fixed vertical drive linear module 74 on the movable block of the horizontal drive linear module 73; and a rotary cylinder 75 fixed on the lifting block of the vertical drive linear module 74. The gripper assembly 71 includes a finger cylinder fixed to the rotary output end of the rotary cylinder 75 and a gripping end fixed to the finger cylinder. A pair of gripping arms; a crossbeam 72 extends from the support rail 411 towards the second support 62. A horizontal drive linear module 73 drives a vertical drive linear module 74 to move horizontally along the crossbeam 72, and a vertical drive linear module 74 drives a rotary cylinder 75 to move vertically. When picking up the second bearing, the rotary cylinder 75 drives the gripper assembly 71 to align coaxially with the second limiting groove 630 and the through hole 631. When placing the bearing, it drives the gripper assembly 71 to align coaxially with the second coaxial positioning boss 420 of the second pressure head 42. With this structure, the combination of the horizontal drive linear module 73 and the vertical drive linear module 74 achieves precise three-dimensional spatial positioning of the gripper assembly 71. The rotary cylinder 75 adjusts the end posture to ensure that the gripper assembly 71 is coaxially aligned with the second limiting groove 630 when picking up and with the second pressure head 42 when placing the bearing. The closed-loop control of the dual linear modules, combined with rotation angle compensation, ensures the spatial orientation accuracy of the bearing during the transfer process and solves the alignment deviation problem when manually transferring bearings.

[0034] like Figure 8 As shown, the locking and fixing mechanism includes a first contour positioning groove 21 and a second contour positioning groove 22, which are spaced vertically and horizontally offset on the pressure-bearing base 2. The shape of the first contour positioning groove 21 matches the contour of the rotating shaft mounting part of the motor housing, and the shape of the second contour positioning groove 22 matches the contour of the motor mounting part of the motor housing. A placement step 23 is formed between the first contour positioning groove 21 and the second contour positioning groove 22 to accommodate the connection between the rotating shaft mounting part and the motor mounting part. With this structure, the vertically offset first contour positioning groove 21 and second contour positioning groove 22 form surface contact constraints with the irregular contours of the rotating shaft mounting part and the motor mounting part of the housing, respectively, preventing the housing from moving on the pressure-bearing base 2 during press-fitting and ensuring press-fitting accuracy.

[0035] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
