Description

Technical Field

[0001] This utility model relates to the field of steering system technology, specifically to a mounting and clamping mechanism for a steering gear servo motor ECU. Background Technology

[0002] Currently, in the field of steering gear servo motor unit assembly, the application of different assembly processes for ECUs of different product models has greatly improved production efficiency and flexibility. Traditional ECU assembly gripper fixtures typically rely on air pipes and wiring harness identification to connect the fixture to the robot equipment for assembly and operation. During the assembly process, the robot gripper fixture needs to firmly grasp the ECU product and rotate it 360° to achieve precise transport from the pallet on the main track of the equipment to the cleaning station for 360° rotational plasma cleaning, and then to the glue injection station for 360° rotational glue injection. After the glue injection is completed, the gripper needs to firmly grasp the product again from the glue injection station and rotate it up and down with 6 degrees of freedom, finally placing it accurately on the moving work platform of the pressing equipment.

[0003] However, in actual production, different models require different ECU gripping fixture mechanisms, necessitating the connection of air hoses and sensor harnesses with different functions. Furthermore, under a 30-second cycle time, due to the large rotation angle and significant operational fluctuations, loose or poorly connected signal harnesses and air hoses often cause intermittent signal interruptions in the ECU gripper fixture, leading to equipment shutdowns. Unstable servo motor ECU assembly positioning also results in assembly pass rate issues. Furthermore, intermittent signal interruptions in the ECU gripper fixture can cause it to detach, posing safety risks. This not only affects production efficiency but also ECU gripping accuracy, requiring adjustments to the robot's trajectory and replacement of gripper fixture cylinder components, which is very expensive and increases maintenance costs and safety hazards. Summary of the Invention

Four first pin holes and four second bolt holes are evenly distributed in the center of the bottom of the circular groove, and the four first pin holes and four second bolt holes are arranged alternately.

[0007] The connecting plate is positioned and connected to the central axis of the robot arm via 4 locating pins and 12 screws.

The upper part of the torque support rod is a U-shaped module structure, and a protruding structure is provided on the lower side of the U-shaped module structure. Two third screw holes are provided on the lower side of the U-shaped module structure. The lower part of the torque support rod is a cylindrical structure.

[0009] The top of the rotating slip ring is provided with a protruding structure that matches the circular groove of the connecting plate, and the top of the rotating slip ring is rotatably connected to the robot arm via the connecting plate.

[0010] The sides of the rotating slip ring are respectively connected to the communication harness and the air passage.

Torque support rod 2 precisely positions and mates with the rotary slip ring 3, ensuring the stability of the communication harness and air source during the rotation driven by the central axis of the robot arm 6, and is secured with two screws. Quick-change plate 4 precisely mates with the rotary slip ring 3 in a symmetrical manner along the central axis, and is secured with four locating pins and six screws. RFID wireless module 5 precisely mates with quick-change plate 4, and is secured with two screws.

[0028] The connecting plate 1 is provided with a first circular groove 1-1. Eight first screw holes 1-2 are evenly distributed on the outer circumference of the bottom of the first circular groove 1-1. Four first pin holes 1-3 and four second bolt holes 1-4 are evenly distributed in the center of the bottom of the circular groove, and the four first pin holes 1-3 and four second bolt holes 1-4 are arranged in an alternating manner.

[0029] The connecting plate 1 is positioned and connected to the central axis of the robot arm 6 by 4 locating pins and 12 screws.

[0030] The connecting plate 1 uses four locating pins and twelve screws to position the central axis of the rotating slip ring 3 and the robot arm 6, ensuring a precise and tight connection. This guarantees the concentricity of the robot arm 6's axis and the rotating slip ring 3's axis, and also ensures the robot's stability during the servo motor ECU assembly process. Structural improvements have been made to address issues such as unstable positioning and low assembly pass rate during servo motor ECU assembly. Furthermore, the superior stability contributes to extending the robot's lifespan.

[0031] The torque support rod 2 has a Y-shaped module structure. The upper part of the torque support rod 2 has a U-shaped module structure, and a protruding structure 2-1 is provided on the lower side of the U-shaped module structure. Two third screw holes 2-2 are provided on the lower side of the U-shaped module structure. The lower part of the torque support rod 2 has a cylindrical structure.

[0032] The torque support rod 2 and the rotating slip ring 3 are precisely positioned and matched to ensure the stability of the robot arm 6 during the axial rotation of the robot arm 6 during the assembly process of the communication harness and air source, which are locked and positioned by two screws.

[0036] The quick-change plate 4 has an oblong shape. A second circular groove 4-1 is located in the middle of the quick-change plate 4. Six fourth screw holes 4-2 are located on the outer side of the second circular groove 4-1, and four second pin holes 4-3 are located on the inner side of the second circular groove 4-1.

[0037] The quick-change disc 4 is positioned and connected to the central axis of the rotating slip ring 3 by 4 locating pins and 6 screws.

[0038] The quick-change plate 4 and the rotary slip ring 3 are precisely assembled in a symmetrical manner along the central axis. They are locked in place by four locating pins and six screws, and are compatible with different models of servo motor ECU assembly tooling for automatic change-up and installation positioning.

[0039] The RFID wireless module 5 is locked and positioned to the side of the quick-change plate 4 by two screws.

[0040] The wireless module 5 and the quick-change plate 4 are precisely matched and locked in place by two screws. It is compatible with the signal data transmission of different models of servo motor ECU assembly tooling. The stability of signal transmission can eliminate signal interruption and shutdown faults, as well as safety issues caused by the ECU gripper tooling falling off.

Therefore, this technological improvement in the steering gear servo motor ECU mounting and clamping mechanism has broad application prospects and significant promotional value in industrial production.
