[0002] Industrial robotic arms are mechanical electronic devices that mimic the functions of human arms, wrists, and hands. They are often used to clamp welding tongs or welding guns, or to carry die-cast or stamped parts or components, as well as perform operations such as laser cutting and spraying. Industrial robotic arms effectively improve production efficiency.

[0003] Existing industrial robotic arms are generally installed and fixed at one working point. Since they cannot be moved, it is inconvenient to perform processing operations on larger components.

However, large pipes are large in size, which makes them inconvenient to move and consumes a lot of energy.

[0004] Therefore, it is particularly important to design a robotic arm motion adjustment mechanism to solve the above-mentioned defects. Utility Model Content

[0023] Example:

[0024] See also Figures 1-4 , the utility model provides a technical solution:

[0025] A robotic arm motion adjustment mechanism includes a mobile base 1, a mobile plate 2 is fixedly installed at the four corners of the bottom of the mobile base 1, a sliding plate 3 is slidably connected to the top of the mobile base 1, a mobile mechanism 4 is fixedly installed between the sliding plate 3 and the mobile base 1, a mounting seat 5 is fixedly installed on the top of the sliding plate 3, a scissor-type folding frame 6 is movably installed on the top of the mounting seat 5, a lifting mechanism 7 is fixedly installed on the bottom end of the scissor-type folding frame 6, a protective cover 8 is fixedly installed on the top of the sliding plate 3 and on the outside of the scissor-type folding frame 6, a lifting platform 9 is movably installed on the top of the scissor-type folding frame 6, and a robotic arm body 10 is fixedly installed on the top of the lifting platform 9.

[0026] First, the bottoms of the multiple sets of moving plates 2 are all rotatably connected to moving wheels 201, and the bottoms of the multiple sets of moving plates 2 and the outer sides of the moving wheels 201 are all threadedly connected to support feet 202. The multiple sets of moving wheels 201 can drive the moving plates 2 to move, so that they can be moved according to the working point of the robot arm body 10. When the working point is reached, the multiple sets of support feet 202 are rotated downward, and then the multiple sets of support feet 202 are fixed to the ground to ensure the stability of the robot arm body 10.

[0027] Furthermore, guide rails 301 are fixedly installed on the front and rear ends of the top of the movable base 1, and the front and rear ends of the bottom of the sliding plate 3 are slidingly connected to the guide rails 301 through the slide 302. When the robot arm body 10 performs processing operations on larger components, the moving mechanism 4 can be used to drive the sliding plate 3 to move left and right. The sliding plate 3 slides on the guide rail 301 under the connection of the slide 302, thereby stably driving the robot arm body 10 to move left and right, and thus there is no need to move the processing components to avoid the problem of high movement energy consumption, thereby further improving the applicability of the robot arm body 10.

[0028] Then, the moving mechanism 4 includes a first motor 401 fixedly installed on the right end of the moving base 1, and a first threaded rod 402 is fixedly installed on the driving end of the first motor 401. The left end of the first threaded rod 402 is rotatably connected to the moving base 1 through a first bearing seat 403. The outer side of the first threaded rod 402 is threadedly connected to a connecting seat 404, and the top of the connecting seat 404 is fixedly connected to the sliding plate 3. When the robotic arm body 10 is working, the first motor 401 is started to drive the first threaded rod 402 to rotate, and under the connection of the connecting seat 404, the sliding plate 3 is driven to move left and right, thereby driving the robotic arm body 10 to move left and right to perform processing operations on larger components.

[0029] Furthermore, the upper and lower ends of the scissor-type folding frame 6 are rotatably connected to the mounting seat 5 and the lifting platform 9 respectively through the connecting head 601, and the upper and lower ends of the scissor-type folding frame 6 are slidingly connected to the mounting seat 5 and the lifting platform 9 respectively through the limiting slide groove 602. The lifting mechanism 7 is used to control the extension and contraction state of the scissor-type folding frame 6, thereby adjusting the height of the lifting platform 9, and then adjusting the height of the robot arm body 10 when processing larger components, further improving the applicability of the robot arm body 10.

[0030] Secondly, the lifting mechanism 7 includes a second motor 701 fixedly mounted on the left end of the mounting seat 5, and a second threaded rod 702 is fixedly mounted on the driving end of the second motor 701 and on the inner side of the scissor-type folding frame 6. The left and right ends of the second threaded rod 702 are rotatably connected to the mounting seat 5 through a second bearing seat 703. The outer side of the second threaded rod 702 is threadedly connected to a connecting frame 704, and the left and right ends of the connecting frame 704 are fixedly connected to the scissor-type folding frame 6. When the height of the robotic arm body 10 is adjusted, the second motor 701 is started to drive the second threaded rod 702 to rotate, and under the connection of the connecting frame 704, one end of the bottom of the scissor-type folding frame 6 is driven to move, thereby controlling the extension and contraction state of the scissor-type folding frame 6, and then adjusting the height of the robotic arm body 10 on the top of the lifting platform 9.

[0031] Finally, the right end of the second threaded rod 702 is fixedly installed with a fixed gear 705, and the right end of the mounting seat 5 and the rear of the fixed gear 705 are slidably connected with a pull rod 706. The front end of the pull rod 706 is meshed with the fixed gear 705 through a fixed tooth block 707. A spring 708 is sleeved on the outer side of the pull rod 706. The upper and lower ends of the fixed tooth block 707 are slidably connected to the mounting seat 5 through a slide rod 709. A latch 710 is passed through the rear end of the pull rod 706, and a fixing hole 711 is opened at the position corresponding to the latch 710 at the right end of the mounting seat 5. When adjusting the height of the robotic arm body 10, first pull the pull rod 706 to move the latch 710 to the position of the fixing hole 711, and then the latch is 710 is inserted into the fixing hole 711 to fix the pull rod 706, thereby controlling the fixed tooth block 707 to release the fixation of the fixed gear 705, so that the second threaded rod 702 can be rotated to adjust the height of the robot arm body 10. After the height adjustment of the robot arm body 10 is completed, the pin 710 is pulled out to release the fixation of the fixing hole 711, and the fixed tooth block 707 fixes the fixed gear 705 under the reset of the spring 708, thereby avoiding the second threaded rod 702 rotating when the robot arm body 10 is working and causing a safety accident. At the same time, during the operation, the protective cover 8 is used to protect the outer side of the scissor-type folding frame 6, further ensuring the safety of the operation of the robot arm body 10.

When the robot arm body 10 performs processing operations on larger components, the moving mechanism 4 can be used to drive the sliding plate 3 to move left and right. The sliding plate 3 slides on the guide rail 301 under the connection of the slide seat 302, thereby stably driving the robot arm body 10 to move left and right, and then there is no need to move the processing components to avoid the problem of high energy consumption in movement. When adjusting the height of the robot arm body 10, first pull the pull rod 706 to move the pin 710 to the position of the fixing hole 711, and then insert the pin 710 into the fixing hole 711 to fix the pull rod 706, thereby controlling the fixed tooth block 707 to release the fixation of the fixed gear 705, and start the second motor 701 to drive the second threaded rod 702 to rotate. Under the connection of the connecting frame 704, one end of the bottom of the scissor-type folding frame 6 is driven to move, thereby controlling the extension and contraction state of the scissor-type folding frame 6, and then adjusting the height of the mechanical arm body 10 on the top of the lifting platform 9. After the height adjustment of the mechanical arm body 10 is completed, the pin 710 is pulled out to release the fixation of the fixing hole 711, and the fixed gear block 707 is fixed to the fixed gear 705 under the reset of the spring 708, thereby avoiding the second threaded rod 702 rotating when the mechanical arm body 10 is working and causing a safety accident. At the same time, the outer side of the scissor-type folding frame 6 is protected by the protective cover 8 during the working process. The entire operation process is simple and convenient. The utility model can be moved according to the working point through design. When processing larger components, the mechanical arm can adjust the working position left and right and up and down, thereby improving the applicability of the mechanical arm and ensuring the safety of the mechanical arm.
