Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a multi-directional adjustable robotic arm equipped with a torque protector. Background Technology

[0002] A robotic arm is a mechanical device composed of multiple joints and links that can achieve multi-degree-of-freedom movement through motors, sensors, and control systems, simulating the flexible operation of a human arm. There are many types of robotic arms, including multi-directional adjustable robotic arms that can install bolts on large tires.

[0003] When using the existing multi-directional adjustable robotic arm, the user pulls the screw connector by hand, causing the screw connector to move downward through the flexible joint of the robotic arm. This allows the user to use the robotic arm to install bolts on large tires using the screw connector. When the robotic arm is not in use, it is in a drooping state. However, when the lower end of the robotic arm is drooping for a long time, the upper end of the robotic arm is subjected to excessive pressure due to the weight of the lower end. Therefore, it is necessary to propose a robotic arm that can assist in supporting the lower end to reduce the weight and pressure on the upper end of the robotic arm. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-4 As shown, this utility model is a multi-directional adjustable robotic arm with a torque protector, comprising:

[0030] A multi-directional adjustment mechanism, comprising a support frame 11 and a screw connector 15;

[0031] The multi-directional adjustment mechanical assembly also includes a connector 12, a rotating frame 13, and a connecting frame 14; the connector 12 is fixed to one side of the top of the support frame 11, the rotating frame 13 is movably connected to the top of the connector 12, the connecting frame 14 is movably connected to the bottom of the rotating frame 13, and the screw connector 15 is located at the bottom of the connecting frame 14.

[0032] The support frame 11 is used for the connection of the connector 12, which is a torque protector. The connector 12 is used for the connection between the support frame 11 and the rotating frame 13. The rotating frame 13 is used for the connection and rotation of the connecting frame 14. The connecting frame 14 is used for the connection of the screw connector 15. The screw connector 15 is used for the installation of bolts for large-size tires.

[0033] The auxiliary support assembly includes a fixed ring 22, a rotating ring 23, a connecting rod 24, and a support table 25. The fixed ring 22 is located on the lower periphery of the support frame 11, the rotating ring 23 is rotatably connected to the outside of the fixed ring 22, the connecting rod 24 is fixed to both sides of one end of the rotating ring 23, the support table 25 is fixed between the outer ends of the connecting rod 24, and the screw connector 15 is located above the support table 25.

[0034] The fixed ring 22 is used for connecting and rotating the rotating ring 23. The rotating ring 23 is used for connecting the connecting rod 24. The connecting rod 24 is used for connecting the rotating ring 23 and the support table 25. The support table 25 is used to provide auxiliary support for the drooping screw connector 15 and the lower end of the robotic arm.

[0035] A fixing rod 21 is fixedly connected between the inner side of the fixing ring 22 and the four sides below the support frame 11. The fixing ring 22 has a groove 27 at the connection with the rotating ring 23.

[0036] The top four corners of the support table 25 are provided with docking grooves 29, and docking rods 28 are inserted into the inner side of the docking grooves 29.

[0037] A soft pad 26 is fixedly connected between the top ends of the connecting rods 28, and the top end of the soft pad 26 is in contact with the bottom end of the screw connector 15;

[0038] The fixing rod 21 is used to connect the fixing ring 22 and the support frame 11. The groove 27 is used to connect the rotating ring 23 and the fixing ring 22. Pushing the connecting rod 24 causes the rotating ring 23 to rotate in the groove 27. The mating groove 29 and the mating rod 28 are used to connect the soft pad 26 and the top of the support table 25. The soft pad 26 is used to protect the bottom of the screw connector 15. The mating rod 28 is inserted into the mating groove 29 so that the soft pad 26 is connected to the top of the support table 25 through the mating rod 28, which makes it easy to replace the soft pad 26.

[0039] Working principle: When the component is not in use, the support table 25 is located on the outside right side of the fixed ring 22. When the component is in use, the positioning pin 36 is removed by hand and the support table 25 is pushed. The support table 25 pushes the rotating ring 23 through the connecting rod 24, so that the rotating ring 23 rotates in the groove 27, causing the support table 25 to rotate to the other side of the support frame 11 through the rotating ring 23. Then the robotic arm drives the screw connector 15 to rotate above the soft pad 26 and places the screw connector 15 above the soft pad 26, so that the support table 25 provides auxiliary support for the screw connector 15 and the lower end of the robotic arm, thereby reducing the gravity and pressure on the upper end of the robotic arm.

[0040] Please see Figures 1-2 , Figures 5-6 As shown, this embodiment, based on the above embodiment, further includes:

[0041] Limiting components;

[0042] The limiting assembly includes a mounting rod 31, a connecting plate 32, and a magnetic block 33; the mounting rod 31 is provided in two sets and is fixed to both sides of the fixing ring 22 respectively; the connecting plate 32 is fixed between the outer ends of the mounting rod 31; and the magnetic block 33 is embedded in the middle of one side of the connecting plate 32.

[0043] Mounting rod 31 is used to connect to connecting plate 32. Each set of mounting rods 31 is located above and below rotating ring 23. Connecting plate 32 is used to connect to magnetic block 33. Magnetic block 33 is used to limit the rotation of connecting rod 24. Magnetic block 33 attracts connecting rod 24 with magnetic force, thereby limiting the rotation of support table 25.

[0044] The magnetic block 33 is attracted to the connecting rod 24. A limit hole 34 is opened on the surface of the magnetic block 33, and a positioning hole 35 is opened on one side of the connecting rod 24.

[0045] The limiting hole 34 and the positioning hole 35 are aligned, and the inner sides of the two are threadedly connected by a positioning pin 36.

[0046] The limiting hole 34 and the positioning hole 35 are used together for the insertion of the positioning pin 36. The positioning pin 36 limits the rotation of the connecting rod 24 and the support table 25. When the connecting rod 24 rotates through the rotating ring 23, it causes the connecting rod 24 to come into contact with one side of the connecting plate 32, and causes the connecting rod 24 to be attracted to the magnetic block 33, so that the limiting hole 34 and the positioning hole 35 on the surface of the two are aligned. Thus, the positioning pin 36 can be inserted into the two, thereby limiting the rotation of the support table 25 and preventing the support table 25 from rotating arbitrarily through the rotating ring 23.

[0047] Working principle: When the component is not in use, the support table 25 is located on the left side of the support frame 11. After the support table 25 is used, the left positioning pin 36 is removed by hand, so that the positioning pin 36 is separated from the limiting hole 34 and the positioning hole 35 through the thread. Then push the support table 25, so that the support table 25 rotates to the right through the connecting rod 24 and the rotating ring 23, so that the connecting rod 24 is in contact with the right side of the connecting plate 32, so that the connecting rod 24 and the magnetic block 33 are attracted by magnetic force, so that the limiting hole 34 and the positioning hole 35 on the surface of the two are aligned. The positioning pin 36 is inserted into the two by hand, thereby limiting the unused support table 25.
