Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to a working arm for industrial robots. Background Technology

[0002] In the field of industrial automation, industrial robots are widely used in production processes such as material handling, assembly, welding, and sorting. The robotic arm, as the core component for performing operations, directly affects the robot's flexibility, precision, and applicability. Traditional industrial robot arms typically consist of multi-section links and drive mechanisms, achieving spatial positioning through multiple degrees of freedom. However, their gripping components often use fixed or bolted connections, making it difficult to quickly change grippers and resulting in poor adaptability to materials of different sizes or shapes. Furthermore, some existing structures lack high-precision support designs at rotary joints, affecting overall motion stability and positioning accuracy, failing to meet the demands of efficient and high-precision modern intelligent manufacturing. Therefore, there is a need for an industrial robot arm with a reasonable structure, flexible gripping, easy gripper replacement, and high-precision control capabilities.

[0003] In the existing technology, the grippers of traditional industrial robots are usually installed by bolt fixing. When it is necessary to clamp materials of different sizes, it is often necessary to replace the corresponding grippers. However, this bolt fixing installation method usually requires the use of special tools during disassembly and installation, and the operation steps are cumbersome. This makes the gripper replacement process complicated and time-consuming, which affects the efficiency and flexibility of the equipment. Utility Model Content

[0026] Example

[0027] Reference Figures 1-4 This is an embodiment of the present invention, which provides a working arm for an industrial robot, comprising:

[0028] The support mechanism 100 includes a base 101, a first motor 102 adapted to be installed at the bottom of the base 101, a first connecting rod 103 fixedly connected to the output end of the first motor 102 via a coupling, and a fixing plate 104 fixedly connected to the outer end face of the first connecting rod 103.

[0029] The drive mechanism 200 includes a second motor 201 adapted to be installed on the outer surface of the fixed plate 104, a guide plate 202 fixedly connected to the output end of the second motor 201, a third motor 203 adapted to be installed on the outer surface of the guide plate 202, an adjustment plate 204 fixedly connected to the output end of the third motor 203, a clamping assembly 205 for fixing materials, and a quick-release assembly 206 for disassembling the clamp.

[0030] The clamping assembly 205 includes a fourth motor 205a adapted to be installed on the outer surface of the adjusting plate 204, a second connecting rod 205b fixedly connected to the output end of the fourth motor 205a via a coupling, a fixed post 205c fixedly connected to the outer end face of the second connecting rod 205b, an arc-shaped guide plate 205d rotatably connected to both sides of the outer end face of the fixed post 205c, and a slider 205e rotatably connected to the outer end face of the arc-shaped guide plate 205d.

[0031] The first motor 102 is used to control the overall rotation angle of the bearing mechanism 100, thereby adjusting the orientation of the working arm in the horizontal plane. The second motor 201 is used to drive the guide plate 202 to move, thereby controlling the longitudinal angle change of the robotic arm, that is, adjusting the posture of the driving mechanism 200 in the vertical direction. The third motor 203 is used to control the horizontal angle of the adjustment plate 204, thereby improving the spatial positioning accuracy and adaptability of the clamping assembly 205.

[0032] Specifically, the quick-release assembly 206 includes a fixing block 206a fixedly installed on the outer surface of the slider 205e, a positioning block 206b fixedly installed on the inner surface of the fixing block 206a, a spring 206c fixedly connected to both sides of the outer surface of the positioning block 206b, a sliding post 206d fixedly connected to the other end of the spring 206c, a sliding groove 206e opened on the inner surface of the fixing block 206a and used in conjunction with the sliding post 206d, a limiting post 206f fixedly installed on both sides of the outer surface of the sliding post 206d, a limiting groove 206g opened on the outer surface of the fixing block 206a and used in conjunction with the limiting post 206f, and a mounting member 206h provided on the outer surface of the fixing block 206a.

[0033] Furthermore, the mounting component 206h includes a mounting block 206h-1 that is attached to the surface of the fixing block 206a, a limiting block 206h-2 that is fixedly mounted on the outer surface of the mounting block 206h-1 and used in conjunction with the limiting post 206f, and a gripper 206h-3 that is fixedly mounted on the outer surface of the mounting block 206h-1.

[0034] When it is necessary to change the clamps of different specifications according to the material size, the sliding columns 206d on both sides of the fixed block 206a can be pressed. At this time, the sliding columns 206d apply pressure to the spring 206c and drive the limiting column 206f to move from one end of the limiting groove 206g to the other end, thereby releasing the contact state between the limiting column 206f and the limiting block 206h-2. Then the mounting block 206h-1 can be easily removed from the fixed block 206a, realizing the quick replacement of the gripper 206h-3 to adapt to the gripping needs of materials of different sizes.

[0035] Furthermore, the first connecting rod 103 penetrates the outer surface of the base 101 and a bearing sleeve for rotation is fixedly installed at the penetration point, and the output end of the third motor 203 penetrates the outer surface of the guide plate 202 and a bearing sleeve for rotation is installed at the penetration point.

[0036] Furthermore, the second connecting rod 205b penetrates the outer surface of the adjusting plate 204 and a bearing sleeve for rotation is installed at the penetration point. The arc-shaped guide plate 205d is rotatably connected to the slider 205e. Bearing sleeves for rotation are installed at both ends of the arc-shaped guide plate 205d where it connects to the fixed column 205c and the slider 205e. The inner surface of the slider 205e slides in contact with the outer surface of the adjusting plate 204.

[0037] Preferably, the outer surface of the sliding post 206d slides in contact with the inner surface of the sliding groove 206e, and the surface of the limiting post 206f is in contact with the surface of the limiting groove 206g.

[0038] It should be noted that the mounting block 206h-1 is in contact with the surface of the fixing block 206a, and the limiting block 206h-2 is in contact with the surface of the limiting post 206f.

[0039] In use, the industrial robot's working arm achieves precise gripping and flexible operation of materials through the coordinated cooperation of the support mechanism 100, drive mechanism 200, gripping assembly 205, and quick-release assembly 206. The support mechanism 100 includes a base 101, a first motor 102 mounted on the bottom of the base 101, a first connecting rod 103 fixedly connected to the output end of the first motor 102 via a coupling, and a fixing plate 104 fixedly connected to the outer end face of the first connecting rod 103. The first connecting rod 103 penetrates the outer surface of the base 101, and a bearing sleeve for rotational support is provided at its penetration point, thereby ensuring the smooth rotation of the first connecting rod 103 under the drive of the first motor 102, and thus controlling the orientation adjustment of the entire working arm in the horizontal plane. The drive mechanism 200 includes a second motor 201, a guide plate 202 fixed to the output end of the second motor 201, a third motor 203 mounted on the guide plate 202, and a connection to the output end of the third motor 203. The system includes an adjustment plate 204, a clamping assembly 205, and a quick-release assembly 206. The second motor 201 drives the guide plate 202 to adjust its longitudinal angle, thus adjusting the robot arm's vertical posture. The output end of the third motor 203 passes through the guide plate 202 and is equipped with a bearing sleeve to ensure its rotational stability and accuracy. It drives the adjustment plate 204 to adjust its horizontal angle, further enhancing the spatial positioning capability of the clamping assembly 205. When different clamps need to be replaced according to material size, quick replacement can be achieved through the quick-release assembly 206. When replacing a clamp, the user only needs to press the sliding posts 206d on both sides of the fixed block 206a. At this time, the sliding posts 206d compress the spring 206c and drive the limiting post 206f to move along the sliding groove 206e, from one end of the limiting groove 206g to the other, releasing the contact between the limiting post 206f and the limiting block 206h-2, allowing the mounting block 206h-1 to be easily removed from the fixed block 206a. Then, the required gripper 206h-3 can be replaced, and the new mounting block 206h-1 can be inserted into the fixing block 206a. After the sliding column 206d is released, the limiting column 206f will automatically reset and re-lock into the limiting groove 206g under the action of the spring 206c, thus completing the quick replacement of the clamp.

[0040] In summary, by designing the quick-release assembly 206, including components such as the fixing block 206a, sliding post 206d, and limiting post 206f, the clamp 206h-3 can be quickly disassembled and assembled without tools. Users only need to press the sliding posts 206d on both sides to move the limiting post 206f from one end of the limiting groove 206g to the other end, releasing the contact state with the limiting block 206h-2, thereby easily removing the mounting block 206h-1, simplifying the clamp replacement process, and improving work efficiency and flexibility.
