Description

Technical Field

[0001] This invention relates to the field of parking actuator assembly, and more specifically to a parking actuator motor assembly press-fitting device. Background Technology

[0002] During the assembly of the parking actuator, the parking actuator motor assembly needs to be installed into the parking actuator housing 5, such as... Figures 2-3 As shown, the parking actuator motor assembly includes a worm gear, motor body, and other structures. Its structure is relatively unique. If conventional clamping components are used to hold the parking actuator motor assembly for transfer, issues such as insecure clamping, inaccurate positioning, and damage to the worm gear threads can easily occur. Furthermore, the parking actuator motor body has a connector plate at its rear end, and... Figure 8 As shown, the PCB board inside the parking actuator housing 5 is provided with irregularly shaped connectors. The connectors need to be accurately embedded in the corresponding irregularly shaped connectors. However, in the prior art, during the process of pressing the parking actuator motor assembly into the housing, due to reasons such as insufficient positioning accuracy, the motor assembly often deforms the irregularly shaped connectors, resulting in assembly failure. Summary of the Invention

[0003] The purpose of this invention is to provide a parking actuator motor assembly press-fitting device that can ensure the assembly quality of the parking actuator motor assembly and improve assembly efficiency.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A parking actuator motor assembly press-fitting device includes a drive mechanism, a motor clamping mechanism, and a connector support assembly. The motor clamping mechanism is mounted on the moving end of the drive mechanism, and the parking actuator motor assembly is clamped by the motor clamping mechanism. The connector support assembly has a lifting seat, and a fixed plate and a movable push plate are sequentially arranged from front to back on the lower side of the lifting seat. The lower end of the fixed plate has a guide block with a through hole, and the lower end of the movable push plate has a support rod, which is inserted into the through hole on the corresponding guide block. The front end has a cross hole, the rear end of the parking actuator motor assembly has a plug plate, and the parking actuator housing has a special-shaped plug piece. During press-fitting, the lifting seat first descends and the upper end of the special-shaped plug piece enters the horizontal hole of the cross hole at the front end of the corresponding guide block. Then, the support rod is moved by the moving push plate, and the front end of the support rod enters the corresponding horizontal hole and is inserted into the corresponding hole on the corresponding special-shaped plug piece. Then, the parking actuator motor assembly is driven to press down by the drive mechanism, and the plug plate enters the corresponding special-shaped plug piece through the vertical hole of the corresponding cross hole.

[0006] The drive mechanism is a three-axis translation mechanism with X and Y-axis degrees of automation and Z-axis degrees of freedom for lifting.

[0007] The motor clamping mechanism includes a first clamping assembly, an intermediate clamping assembly, and a second clamping assembly arranged sequentially. The parking actuator motor assembly includes a motor body and a worm gear located at the front of the motor body. The front end of the worm gear is provided with a worm gear positioning member, which is clamped by the first clamping assembly. The rear end of the worm gear is clamped by the intermediate clamping assembly. The motor body is clamped by the second clamping assembly. The gripper fingers of the intermediate clamping assembly open and close radially along the worm gear, while the grippers of the first clamping assembly and the grippers of the second clamping assembly open and close axially along the worm gear.

[0008] The first clamping assembly includes a first guide cylinder, a first movable jaw, and a first fixed jaw, wherein the first movable jaw is driven by the first guide cylinder to move along the worm gear axis and engage with the first fixed jaw.

[0009] The second clamping assembly includes a second guide cylinder, a second movable jaw, and a second fixed jaw, wherein the second movable jaw is driven by the second guide cylinder to move along the worm gear axis and engage with the second fixed jaw.

[0010] The intermediate clamping assembly includes an intermediate gripper cylinder and gripper fingers that are driven to open and close radially along the worm gear by the intermediate gripper cylinder.

[0011] The connector support assembly includes a lifting cylinder, a lifting seat, a movable push plate, and a movable push plate cylinder. The lifting seat is connected to the lifting cylinder. The fixed plate is provided on the lower front side of the lifting seat. The movable push plate cylinder and a displacement sensor are provided on the lower rear side of the lifting seat. The movable push plate is located on the lower side of the lifting seat and is driven to move by the movable push plate cylinder.

[0012] The drive mechanism, connector support assembly, and parking actuator housing are all mounted on a base. A bracket is provided on one side of the base, and the connector support assembly is provided at the end of the bracket. A support frame supporting the drive mechanism is provided on the other side of the base, and the parking actuator housing is located between the bracket and the support frame.

[0013] The advantages and positive effects of this invention are as follows:

[0014] 1. This invention utilizes the support rod, guide block, and movable push plate in the connector support assembly to achieve accurate support and positioning of irregularly shaped connectors. Furthermore, the longitudinal hole of the cross hole at the front end of the guide block guides the connector plate at the rear end of the parking actuator motor assembly to accurately enter and install into the corresponding irregularly shaped connector, preventing deformation of the irregularly shaped connector, ensuring assembly quality, and improving assembly efficiency.

[0015] 2. The motor clamping mechanism of the present invention, in conjunction with the structural features of the parking actuator motor assembly, is equipped with multiple sets of clamping components for clamping different parts of the motor assembly, ensuring reliable clamping. At the same time, the gripper fingers of the middle clamping component open and close radially along the worm, while the grippers of the first and second clamping components open and close axially along the worm, thereby achieving clamping of the parking actuator motor assembly from both horizontal X and Y directions, ensuring accurate assembly positioning and preventing axial displacement of the motor assembly.

Figure 8 As shown, the PCB board inside the parking actuator housing 5 is equipped with a non-standard connector 7. During press-fitting, the lifting seat 4023 first descends to the set height, and as shown... Figure 5 As shown, the upper end of the irregularly shaped connector 7 moves relative to the horizontal hole 4072 of the corresponding cross hole 407, and then the support rod 405 is driven by the moving push plate 403 to move along the corresponding through hole 408, and as shown... Figure 8As shown, the front end of the support rod 405 enters the horizontal hole 4072 of the cross hole 407 and is inserted into the corresponding hole on the irregular plug-in 7, thereby achieving the purpose of using the support rod 405 to position and support the irregular plug-in 7. Then, the parking actuator motor assembly 3 is driven to press down and install by the drive mechanism 1, and the plug-in plate 301 at the rear end of the parking actuator motor assembly 3 enters the corresponding irregular plug-in 7 through the vertical hole 4071 of the corresponding cross hole 407.

[0027] like Figure 1 As shown, in this embodiment, the drive mechanism 1 is a three-axis translation mechanism, which has X and Y direction movement auto-degrees and Z direction lifting freedom.

[0028] like Figure 1 As shown, in this embodiment, the drive mechanism 1 includes a support frame, an X-axis moving component 101, a Y-axis moving component 102, and a Z-axis lifting component 103. Each of the X-axis moving component 101, Y-axis moving component 102, and Z-axis lifting component 103 includes a moving seat and a drive cylinder. The X-axis moving seat is slidably connected to the support frame and driven to move by an X-axis drive cylinder located on the upper end of the support frame. The Y-axis moving seat is slidably connected to the X-axis moving seat and driven to move by a Y-axis drive cylinder located on the X-axis moving seat. The Z-axis moving seat is slidably connected to the Y-axis moving seat and driven to lift and lower by a Z-axis drive cylinder located on the Y-axis moving seat. The lower end of the Z-axis moving seat is fixedly connected to the motor clamping mechanism 2. The drive cylinder is a technology known in the art and is a commercially available product.

[0029] like Figure 3 As shown, in this embodiment, the motor clamping mechanism 2 includes a mounting plate 208 and multiple sets of clamping components disposed on the lower side of the mounting plate 208. The mounting plate 208 is fixedly connected to the lower end of the Z-direction moving seat of the drive mechanism 1, thereby driving the entire motor clamping mechanism 2 to move.

[0030] like Figure 3 As shown, the mounting plate 208 has a first clamping assembly, an intermediate clamping assembly, and a second clamping assembly arranged sequentially on its lower side. The parking actuator motor assembly 3 includes a motor body and a worm gear located on the front side of the motor body. The front end of the worm gear has a worm gear positioning member, which is clamped by the first clamping assembly. The rear end of the worm gear is clamped by the intermediate clamping assembly, and the motor body is clamped by the second clamping assembly. The first clamping assembly and the intermediate clamping assembly clamp the two ends of the worm gear respectively without affecting the worm gear thread.

[0031] like Figure 3As shown, in this embodiment, the first clamping assembly includes a first guide cylinder 201, a first movable gripper 202, and a first fixed gripper 203. The first guide cylinder 201 and the first fixed gripper 203 are both located on the lower side of the mounting plate 208. The first movable gripper 202 is driven by the first guide cylinder 201 to move along the worm gear axis and cooperates with the first fixed gripper 203 to clamp the worm gear positioning component.

[0032] like Figure 3 As shown, the second clamping assembly includes a second guide cylinder 206, a second movable gripper 205, and a second fixed gripper 204. The second guide cylinder 206 and the second fixed gripper 204 are both located on the lower side of the mounting plate 208. The second movable gripper 205 is driven by the second guide cylinder 206 to move along the worm gear axis and cooperates with the second fixed gripper 204 to clamp the motor body.

[0033] like Figure 3 As shown, the intermediate clamping assembly includes an intermediate gripper cylinder 207 and gripper fingers 209 that are driven to open and close radially along the worm gear by the intermediate gripper cylinder 207.

[0034] like Figures 4-8 As shown, in this embodiment, the connector support assembly 4 includes a lifting cylinder 401, a lifting seat 4023, a movable push plate 403, and a movable push plate cylinder 404. The lifting seat 4023 is connected to the cylinder rod end of the lifting cylinder 401. The lower front end of the lifting seat 4023 is provided with the fixed plate 4022. The lower rear end of the lifting seat 4023 is provided with the movable push plate cylinder 404 and a displacement sensor 406. The movable push plate 403 is located on the lower side of the lifting seat 4023 and is driven to move by the movable push plate cylinder 404. The displacement sensor 406 is used to detect the displacement of the movable push plate 403 in real time, thereby controlling the displacement of the support rod 405.

[0035] like Figure 1 As shown, the drive mechanism 1, the connector support assembly 4, and the parking actuator housing 5 are all mounted on a base 6. One side of the base 6 is provided with an inverted L-shaped bracket 601, and the end of the bracket 601 is provided with the connector support assembly 4. The other side of the base 6 is provided with a support frame for the drive mechanism 1. The parking actuator housing 5 is mounted on a support seat between the bracket 601 and the support frame.

[0036] The working principle of this invention is as follows:

[0037] When this invention is in operation, the motor clamping mechanism 2 clamps the parking actuator motor assembly 3 to be installed from other workstations, and drives it to be transported to the assembly station on the base 6 via the drive mechanism 1, wherein... Figure 3As shown, the motor clamping mechanism 2 is configured with a first clamping component, an intermediate clamping component, and a second clamping component according to the structural characteristics of the parking actuator motor assembly 3. The worm positioning component at the front end of the worm of the parking actuator motor assembly 3 is clamped by the first clamping component, the rear end of the worm is clamped by the intermediate clamping component, and the motor body is clamped by the second clamping component. The gripper fingers 209 of the intermediate clamping component open and close radially along the worm, and the grippers of the first clamping component and the grippers of the second clamping component open and close axially along the worm, thereby achieving clamping of the parking actuator motor assembly 3 in both horizontal X and Y directions, ensuring reliable clamping while also ensuring accurate assembly positioning.

[0038] After the parking actuator motor assembly 3 is moved to the assembly station above the base 6, the connector support assembly 4 is activated to support the irregular connector 7. The lifting cylinder 401 of the connector support assembly 4 first drives the lifting seat 4023 to descend to a set height. At this time, the upper end of the irregular connector 7 moves relative to the horizontal hole 4072 of the cross hole 407 at the front end of the corresponding guide block 4021. Then, the moving push plate cylinder 404 of the connector support assembly 4 is activated to drive the moving push plate 403 forward. The moving push plate 403 drives the support rod 405 to move along the through hole 408 on the corresponding guide block 4021. Furthermore, the front end of the support rod 405 enters the corresponding hole on the irregular plug-in 7 in the corresponding horizontal hole 4072, thereby achieving the support and positioning of the irregular plug-in 7. Then, the Z-axis lifting component 103 in the drive mechanism 1 starts to drive the parking actuator motor assembly 3 to press down for installation. During the pressing process, the plug-in plate 301 at the rear end of the parking actuator motor assembly 3 enters the corresponding irregular plug-in 7 through the longitudinal hole 4071 of the cross hole 407 at the front end of the corresponding guide block 4021, thereby achieving the installation of the motor assembly in place. This prevents the irregular plug-in 7 from being deformed, ensuring assembly quality while also improving assembly efficiency.
