Description

Technical Field

[0001] This utility model relates to the field of industrial robot robotic arm technology, and in particular to a lightweight robotic arm structure for industrial robots. Background Technology

[0002] Industrial robots are a common type of industrial equipment. They can perform industrial processing and control, thereby saving manpower. Industrial robots have a wide range of applications. Existing industrial robots typically include a robot arm body, a robotic arm, and a base. The base supports the robot, and the robotic arm is located on the robot arm body. The robotic arm can typically perform gripping, moving, or other operations on workpieces. The length of the robotic arm is usually mechanically set according to requirements.

[0003] Currently, robotic arms are equipped with mechanical grippers for grasping objects. When using a robotic arm robot, the gripper is usually needed to move the object. Since the robotic arm robot may use the gripper to grasp objects of different heights and sizes, the operator usually needs to change the gripper when the object's height and size are different. Because most existing lightweight robotic arms have the gripper and robotic arm fixedly installed, it is inconvenient for operators to disassemble and replace the gripper. In addition, the size of the gripper is usually fixed and cannot be adjusted, which affects the convenience of the robotic arm robot in grasping objects of different heights and sizes, reduces the applicability of the robotic arm robot, and reduces its practicality. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a lightweight robotic arm structure for industrial robots. This structure can solve the problem that the size of the robotic gripper is usually fixed and cannot be adjusted, which affects the convenience of the robotic arm robot in grasping objects of different heights and sizes, reduces the applicability of the robotic arm robot, and reduces the practicality of the robotic arm robot.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight robotic arm structure for industrial robots, comprising a mechanical base and a mechanical gripper adjustment device; a rotating arm is mounted on the top of the mechanical base, a rotating rod is rotatably mounted on the rotating arm, a fixed box is fixedly connected to the lower end of the rotating rod, a groove is provided at the bottom of the fixed box, and two cross-shaped sliders are slidably connected inside the groove; the mechanical gripper adjustment device comprises two movable plates, mechanical grippers, T-shaped sliders and bolts, the two movable plates are respectively fixedly connected to the bottom of the two cross-shaped sliders, the mechanical grippers are fixedly connected to the bottom of the movable plates, five mechanical grippers are linearly and equidistantly distributed at the bottom of the movable plates, a T-shaped groove is provided at the bottom of the mechanical grippers, and the T-shaped sliders are slidably connected inside the T-shaped groove.

[0006] Preferably, the surfaces of both cross-shaped sliders are rotatably connected to a rotating shaft, and the surfaces of both rotating shafts are rotatably connected to a supporting inclined rod.

[0007] Preferably, a hydraulic lift is fixedly mounted on the surface of the rotating rod, and two protrusions are fixedly mounted on the output end of the hydraulic lift.

[0008] Preferably, the upper ends of the two supporting diagonal rods are rotatably connected to the inside of the two protrusions.

[0009] Preferably, the surface of the T-shaped slider is provided with fixing holes, which are linearly and equidistantly distributed on the surface of the T-shaped slider.

[0010] Preferably, the bolt is installed at the lower end of the mechanical gripper, with one end of the bolt located inside the fixing hole.

[0011] Preferably, the five mechanical grippers have the same internal structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This lightweight robotic arm structure for industrial robots can grip and move objects of different heights and sizes using mechanical grippers and T-shaped sliders. When gripping objects of smaller heights, the T-shaped slider can be moved out of the mechanical grippers, reducing the overall weight of the robotic arm structure, lowering energy consumption, and saving power. By fixing the T-shaped slider inside the mechanical grippers, the robotic arm robot's ability to grip objects of different heights and sizes is improved, increasing its applicability and practicality.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a lightweight robotic arm structure for industrial robots, including a mechanical base 1 and a mechanical gripper adjustment device. A rotating arm 2 is installed on the top of the mechanical base 1, and a rotating rod 3 is rotatably installed on the rotating arm 2. A fixed box 4 is fixedly connected to the lower end of the rotating rod 3. A slide groove 5 is opened at the bottom of the fixed box 4. Two cross-shaped sliders 6 are slidably connected inside the slide groove 5. A rotating shaft 7 is rotatably connected to the surface of each of the two cross-shaped sliders 6. A support rod 8 is rotatably connected to the surface of each of the two rotating shafts 7. A hydraulic lift 9 is fixedly installed on the surface of the rotating rod 3. Two protrusions 10 are fixedly installed at the output end of the hydraulic lift 9. The upper ends of the two support rods 8 are rotatably connected to the inside of the two protrusions 10 respectively.

[0025] The mechanical gripper adjustment device includes two movable plates 11, mechanical grippers 12, T-shaped sliders 14, and bolts 16. The two movable plates 11 are fixedly connected to the bottom of the two cross-shaped sliders 6, and the mechanical grippers 12 are fixedly connected to the bottom of the movable plates 11. The five mechanical grippers 12 are linearly and equidistantly distributed on the bottom of the movable plates 11. The bottom of the mechanical grippers 12 is provided with a T-shaped groove 13, and the T-shaped sliders 14 are slidably connected inside the T-shaped grooves 13. The surface of the T-shaped sliders 14 is provided with fixing holes 15, which are linearly and equidistantly distributed on the surface of the T-shaped sliders 14. The bolts 16 are installed at the lower end of the mechanical grippers 12, and one end of the bolts 16 is opened inside the fixing holes 15. The five mechanical grippers 12 have the same internal structure.

[0026] The rotating arm 2 can rotate on the mechanical base 1 and drive the rotating rod 3 to move to the position of the object. The rotating rod 3 rotates and drives the fixed box 4 to rotate to the lower position. At this time, the mechanical gripper 12 is perpendicular to the ground. Finally, the mechanical grippers 12 on the left and right sides are moved downward and moved to the left and right sides of the object. Finally, after starting the hydraulic lift 9, the output end of the hydraulic lift 9 slides upward and drives the two protrusions 10 to slide upward. The two protrusions 10 slide upward and drive the two support rods 8 to rotate. The two support rods 8 rotate and drive the two rotating shafts 7 to slide relative to each other. The two rotating shafts 7 slide relative to each other and drive the two cross-shaped sliders 6 and the two moving plates 11 to slide relative to each other. The two moving plates 11 slide relative to each other and drive the mechanical grippers 12 on the left and right sides to slide relative to each other and clamp on the left and right sides of the object. Finally, the rotating arm 2 can drive the object to move its position through the mechanical grippers 12.

[0027] When a worker needs to grip objects of different heights, they can remove the T-shaped slider 14 and slide it into the T-shaped groove 13. Then, the worker rotates the bolt 16 with a wrench, causing it to rotate and engage with the fixing hole 15. This fixes the T-shaped slider 14 inside the mechanical gripper 12. The surface of the T-shaped slider 14 has four fixing holes 15, allowing the worker to adjust the length of the T-shaped slider 14 extending out of the mechanical gripper 12 according to the object's height. Thus, objects of different heights can be gripped and moved using the mechanical gripper 12 and the T-shaped slider 14. When gripping smaller objects, the T-shaped slider 14 can be moved out of the mechanical gripper 12, reducing the overall weight of the robotic arm structure, lowering energy consumption, and saving power. By fixing the T-shaped slider 14 inside the mechanical gripper 12, the convenience of gripping objects of different heights is improved, increasing the robotic arm's applicability and practicality.
