Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a robot wrist joint steering structure. Background Technology

[0002] The robotic arm is a crucial component at the robot's joints. Existing robotic arms typically rotate their wrists in the same way as human wrists, allowing only lateral rotation and preventing reverse rotation. This significantly reduces operational efficiency in scenarios requiring rapid direction changes or obstacle avoidance. To address this, we propose a robotic wrist joint steering structure to facilitate reverse rotation of the robotic arm's wrist joint, thereby improving the robot's operational efficiency. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a robot wrist joint steering structure.

[0004] The technical solution adopted by this utility model to solve its technical problem is a robot wrist joint steering structure, including a robotic arm body. Two symmetrical L-shaped plates are fixedly connected to one end of the robotic arm body by bolts. A connecting plate is installed at one end of the robotic arm body by bolts. A dual-head motor is installed at the other end of the connecting plate. The output end of the dual-head motor is fixedly connected to the wall of a concave frame. A robotic forearm is connected to the wall of the concave frame by bolts.

[0005] By adopting the above technical solution, when the robot's wrist joint is rotated in the reverse direction, the main body of the robotic arm is connected to the dual-head motor through the I-shaped connecting plate. Since the output end of the dual-head motor is fixedly connected to the wall of the concave frame, the dual-head motor can drive the concave frame to rotate. Since the concave frame is located between the L-shaped plates and is connected to one end of the robotic forearm, when the dual-head motor rotates in the forward direction, the dual-head motor drives the concave frame to rotate in the forward direction. When the dual-head motor rotates in the reverse direction, the concave frame rotates in the reverse direction between the walls of the L-shaped plates. Thus, the main body of the robotic arm drives the robotic forearm to rotate in the reverse direction, and the robotic forearm drives the robotic hand to rotate. This improves the operating efficiency in scenarios where the robotic arm can quickly switch directions or bypass obstacles.

[0006] Specifically, the output end of the dual-head motor is rotatably connected to the wall of the L-shaped plate via a bearing.

[0007] By adopting the above technical solution, the output end of the dual-head motor rotates on the wall of the L-shaped plate.

[0008] Specifically, a rotary motor is bolted to the other end of the robotic arm, and a disc is mounted on the output end of the rotary motor. The disc wall is bolted to one end of the robotic arm.

[0009] By adopting the above technical solution, a rotary motor drives a disc at its output end. Since the disc is connected to the robot arm, the rotary motor drives the robot arm to rotate.

[0010] Specifically, the other end of the main body of the robotic arm is provided with a connecting rod, and the other end of the connecting rod is welded with a connecting plate, and a through hole is opened in the wall of the connecting plate.

[0011] By adopting the above technical solution, the external bolt is connected to the robot through the through hole, thereby connecting the disk to the robot.

[0012] Specifically, the connecting plate is in the shape of an I-beam.

[0013] By adopting the above technical solution, the connecting plate, which is shaped like an I-beam, facilitates the connection between the main body of the robotic arm and the dual-head motor.

[0014] The beneficial effects of this utility model are:

[0015] (1) The robot wrist joint steering structure described in this utility model, when the robot wrist joint is rotated in the reverse direction, the main body of the robotic arm is connected to the dual-head motor through the I-shaped connecting plate. Since the output end of the dual-head motor is fixedly connected to the wall of the concave frame, the dual-head motor can drive the concave frame to rotate. Since the concave frame is located between the L-shaped plates, the concave frame is connected to one end of the robotic forearm. Thus, when the dual-head motor rotates in the forward direction, the dual-head motor drives the concave frame to rotate in the forward direction. When the dual-head motor rotates in the reverse direction, the concave frame rotates in the reverse direction between the walls of the L-shaped plates. Thus, the main body of the robotic arm drives the robotic forearm to rotate in the reverse direction, and the robotic forearm drives the robotic hand to rotate. This improves the operating efficiency in scenarios where the robotic arm can quickly switch directions or bypass obstacles.

[0016] (2) The robot wrist joint steering structure described in this utility model has a dual-head motor output end connected to an L-shaped plate. The output end of the dual-head motor rotates on the wall of the L-shaped plate. The output end of the motor drives the disc at its output end through a rotary motor. Since the disc is connected to the robot arm, the rotary motor drives the robot arm to rotate. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the robot wrist joint steering structure of this utility model includes a robotic arm body 1. Two symmetrical L-shaped plates 2 are fixedly connected to one end of the robotic arm body 1 by bolts. A connecting plate 9 is installed at one end of the robotic arm body 1 by bolts. A dual-head motor 8 is installed at the other end of the connecting plate 9. The output end of the dual-head motor 8 is fixedly connected to the wall of the concave frame 4. A robotic forearm 3 is connected to the wall of the concave frame 4 by bolts.

[0024] In use, when the robot's wrist joint is rotated in the reverse direction, the main body 1 of the robotic arm is connected to the dual-head motor 8 through the I-shaped connecting plate 9. Since the output end of the dual-head motor 8 is fixedly connected to the wall of the concave frame 4, the dual-head motor 8 can drive the concave frame 4 to rotate. Since the concave frame 4 is located between the L-shaped plates 2, and the concave frame 4 is connected to one end of the robotic forearm 3, when the dual-head motor 8 rotates in the forward direction, the dual-head motor 8 drives the concave frame 4 to rotate in the forward direction. When the dual-head motor 8 rotates in the reverse direction, the concave frame 4 rotates in the reverse direction between the plates of the L-shaped plates 2. Thus, the main body of the robotic arm 1 drives the robotic forearm 3 to rotate in the reverse direction, and the robotic forearm 3 drives the robotic hand 7 to rotate. This improves the operating efficiency in scenarios where the robotic arm can quickly switch directions or bypass obstacles.

[0025] like Figure 1 and Figure 2 As shown, the output end of the dual-head motor 8 is rotatably connected to the wall of the L-shaped plate 2 via a bearing.

[0026] During use, the output end of the dual-head motor 8 rotates on the wall of the L-shaped plate 2.

[0027] like Figure 2 and Figure 3As shown, a rotary motor 6 is bolted to the other end of the robotic arm 3, and a disc 10 is mounted on the output end of the rotary motor 6. The disc wall of the disc 10 is bolted to one end of the robotic arm 7.

[0028] In use, the rotary motor 6 drives the disk 10 at its output end. Since the disk 10 is connected to the robot arm 7, the rotary motor 6 drives the robot arm 7 to rotate.

[0029] like Figure 2 As shown, the other end of the main body 1 of the robotic arm is provided with a connecting rod 11, and the other end of the connecting rod 11 is welded with a connecting plate 5. A through hole 12 is provided on the wall of the connecting plate 5.

[0030] In use, the external bolt is inserted through the through hole 12 to connect the external bolt to the robot, thereby connecting the disk 10 to the robot.

[0031] like Figure 1 As shown, the connecting plate 9 is in the shape of an I-beam.

[0032] In use, the robotic arm body 1 and the dual-head motor 8 can be easily connected through the I-shaped connecting plate 9.

[0033] In use, when the robot's wrist joint is rotated in the reverse direction, the main body 1 of the robotic arm is connected to the dual-head motor 8 via the I-shaped connecting plate 9. Since the output end of the dual-head motor 8 is fixedly connected to the wall of the concave frame 4, the dual-head motor 8 can drive the concave frame 4 to rotate. Because the concave frame 4 is located between the L-shaped plates 2 and is connected to one end of the robotic forearm 3, when the dual-head motor 8 rotates in the forward direction, it drives the concave frame 4 to rotate in the forward direction; when the dual-head motor 8 rotates in the reverse direction... When the concave frame 4 rotates in the opposite direction between the walls of the L-shaped plate 2, the main body 1 of the robotic arm drives the robotic arm 3 to rotate in reverse, and the robotic arm 3 drives the robotic hand 7 to rotate, thereby improving the operation efficiency in scenarios where the robotic arm can quickly switch directions or bypass obstacles. The output end of the dual-head motor 8 is connected to the L-shaped plate 2, and the output end of the dual-head motor 8 rotates on the wall of the L-shaped plate 2. The output end of the dual-head motor 8 drives the disk 10 at its output end through the rotary motor 6. Since the disk 10 is connected to the robotic hand 7, the rotary motor 6 drives the robotic hand 7 to rotate.
