However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0022] Embodiment 1: As Figure 1 - Figure 4 shown, the present utility model provides an auxiliary device for replacing a tool at the end of a robotic arm, including a housing 1. A sleeve 8 is slidably connected inside the housing 1. A first threaded hole 9 is opened at the upper end of the sleeve 8. An adjusting assembly 20 is threadedly connected inside the first threaded hole 9. A top cover 10 is arranged at the upper end of the adjusting assembly 20. A support plate 14 is arranged below the middle inside the housing 1. On both sides of the middle of the upper end of the support plate 14, first limiting frames 16 are fixedly connected. An electric telescopic rod 17 is installed inside the first limiting frames 16. On both sides of the middle of the lower end inside the sleeve 8, second limiting frames 18 are fixedly connected. The output end of the electric telescopic rod 17 is inserted into the second limiting frames 18.
[0023] The specific settings and functions of this embodiment will be described in detail below. Through the settings of the adjusting assembly 20 and the electric telescopic rod 17, due to the differences in the tools at the end of the robotic arm, the adjusting assembly 20 is connected to the first threaded holes 9 at different positions. By rotating, the connection height between the adjusting assembly 20 and the first threaded hole 9 is adjusted, so that the position of the upper end of the top cover 10 is moved, and the tool at the end of the robotic arm can be supported. In this way, after the tool at the end of the robotic arm to be replaced is disassembled, the tool to be used is placed between the top covers 10 and supported by the top covers 10. The housing 1 is moved below the robotic arm, the electric telescopic rod 17 is extended, and the position of the housing 1 is adjusted until the connection between the tool and the robotic arm is made. Subsequently, the tool is fixed to the robotic arm. Using it in this way does not require manual support, reducing the installation difficulty and labor use.
[0024] Embodiment 2: As Figure 1 - Figure 4As shown in the figure, a bottom cavity 19 is opened below the middle inside the outer shell 1. A power supply battery 12 is installed inside the bottom cavity 19. The power supply battery 12 is electrically connected to the electric telescopic rod 17. A limiting snap ring 13 is clamped at the upper end of the bottom cavity 19. The support plate 14 is lapped above the limiting snap ring 13. The lower surface of the limiting snap ring 13 is attached to the upper surface of the power supply battery 12. A reinforcing rib 15 is fixedly connected to the lower end of the support plate 14. Universal wheels 4 are fixedly connected to the four corners at the lower end of the outer shell 1. A charging port 2 and a control button 3 are arranged on one side of the outer shell 1. The control button 3 and the charging port 2 are both electrically connected to the power supply battery 12. A limiting groove 22 is opened at the outer edge of the upper end of the adjusting component 20. A rubber sleeve 11 is sleeved outside the limiting groove 22. A second threaded hole 21 is opened in the middle of the upper end of the adjusting component 20. A threaded rod 23 is threadedly connected inside the second threaded hole 21. The threaded rod 23 is fixedly connected to the top cover 10. Card slots 7 are opened at the four corners of the upper end of the sleeve holder 8. Corner brackets 6 are clamped inside the card slots 7. A limiting support frame 5 is fixedly connected between the upper ends of the four corner brackets 6.
[0025] The effect achieved by the entire embodiment is that through the setting of the limiting snap ring 13, it is used to limit the position of the power supply battery 12 to ensure the stability of the power supply battery 12 during use. The support plate 14 and the limiting snap ring 13 adopt a separate design, which can prevent the power supply battery 12 from being squeezed when the support plate 14 is deformed. The position of the electric telescopic rod 17 is located at the edge, thus further preventing the occurrence of deformation. Through the setting of the limiting support frame 5, when adjusting the position of the top cover 10, the tool at the end of the robotic arm can be placed on the limiting support frame 5, and the tool is limited by the limiting support frame 5. After the adjustment is completed, the limiting support frame 5 is taken out to avoid interfering with the installation of the tool. Through the split setting of the top cover 10 and the adjusting component 20, according to different tools to be installed at the end of the robotic arm, different-sized top covers 10 can be replaced for use, so as to adapt to different-sized tools. Through the setting of the rubber sleeve 11, it is used to reduce the wear on the fingers and is more convenient for rotational adjustment.
[0026] The usage method and working principle of this device: When in use, connect the corner bracket 6 with the card slot 7, then place the tool to be installed at the end of the robotic arm on the limiting support frame 5, and press the tool to ensure its stability. Then rotate the adjusting component 20 in different first threaded holes 9 to adjust the position of the top cover 10 until the upper end of the top cover 10 contacts the tool, thus completing the adjustment. Then take out the tool and the limiting support frame 5, place the tool between the top covers 10, push the outer shell 1 to move, move the tool to the side of the robotic arm, disassemble the tool on the robotic arm, and then install the replaced tool at the end of the robotic arm. During this period, by controlling the telescopic movement of the electric telescopic rod 17 and adjusting the position of the outer shell 1, the connection part of the tool is brought into contact connection with the end of the robotic arm. Then retract the electric telescopic rod 17 to the bottom end and move out the outer shell 1.
