The mechanical arm positioning system in the prior art mostly adopts fixed supports or manual adjustment mode, the adjustment accuracy is not high, and manual operation is required, which leads to low efficiency. For example, in some traditional positioning systems, workers need to manually adjust the position of the support or the mechanical arm, which is time-consuming and laborious and prone to errors. This not only affects the work efficiency, but also increases the complexity of operation. In addition, the traditional mechanical arm installation and disassembly method is usually complex, involving multiple steps and tools, and requires a long preparation and adjustment time. This installation method not only has low efficiency, but also greatly limits the flexibility of the equipment for production lines that need to frequently change tasks.

The mechanical hand main body 1 is the core part of the whole device, is responsible for performing specific task operations such as grabbing, carrying and assembling, and can accurately and efficiently complete these tasks through the positioning auxiliary device. The workbench 6 is used for providing a stable support platform, and the mechanical hand relies on the support of the workbench 6 during the working process, a plurality of parts are installed on the top of the workbench 6, and the slide rail 7 and the scale mark 2 are fixedly connected, so as to realize the positioning of the mechanical hand main body 1 and ensure the accuracy during work. The slide rail 7 is used for providing a smooth sliding path, so that the base 10 can accurately move in a specific direction on the workbench 6. The base 10 is a moving support part of the whole device, is carried and slides on the slide rail 7. The positioning mechanism is installed outside the base 10 and is used for adjusting the position of the mechanical hand, a plurality of fixed blocks 9 are fixedly connected on the top of the base 10, so as to ensure the stable connection of the fixed blocks 9 and the mechanical hand. The fixed blocks 9 are used for stabilizing and fixing the base 10, are arranged in a ring shape and provide accurate positioning of the mechanical hand, so that the mechanical hand main body 1 can be accurately installed on the base 10, and the locking mechanism is arranged in the two symmetrical fixed blocks 9, and is used for fixing the T-shaped plug block 8. The T-shaped plug block 8 is connected to the outside of the mechanical hand main body 1 and is used for cooperating with the insertion slot in the fixed block 9, so that the mechanical hand main body 1 can be fixed on the base 10 through the fixed block 9, and the mechanical hand main body 1 is convenient to install or disassemble. The extension plate 4 increases the action range of the workbench 6, provides installation support for the cylinder 5, adjusts the movement of the base 10 through the control of the cylinder 5, provides a larger operation space and enhances the flexibility of the device.

[0034] Reference Figure 3 and Figure 4The locking mechanism comprises a shell 16 fixedly connected inside the fixed block 9, an inner shell 15 fixedly connected inside the shell 16, a bolt 14 slidably connected inside the inner shell 15, a spring 21 sleeved outside the bolt 14, a self-locking assembly provided outside the bolt 14, the bolt 14 inserted into the T-shaped plug block 8, and a pull ring fixedly connected to the end of the bolt 14 away from the fixed block 9. The shell 16 is used for bearing various parts inside it to ensure normal operation. The inner shell 15 is used for providing a sliding track for the bolt 14 to ensure that the bolt 14 can be smoothly inserted into the T-shaped plug block 8, thereby achieving the installation and fixation of the manipulator main body 1. The self-locking assembly is used for temporarily locking the bolt 14 after the bolt 14 is pulled out, without having to continuously pull the bolt 14. The pull ring is used for conveniently pulling the bolt 14.

[0035] With reference to Figure 3 and Figure 4 The self-locking assembly comprises an arc-shaped groove 17 and an L-shaped groove 18. The L-shaped groove 18 is formed on the outer side of the inner shell 15, and the arc-shaped groove 17 is formed on the side of the shell 16 away from the fixed block 9. The bolt 14 is fixedly connected with a backing plate 13, the backing plate 13 is fixedly connected with an L-shaped rod 19, one end of the spring 21 is fixedly connected to one side of the backing plate 13, the other end of the spring 21 abuts against the inner wall of the inner shell 15, the L-shaped rod 19 is slidably connected inside the L-shaped groove 18, the L-shaped rod 19 is slidably connected inside the arc-shaped groove 17, and the backing plate 13 is slidably connected inside the inner shell 15. The backing plate 13 is used for fixing the L-shaped rod 19 and bearing the spring 21, and the elastic force of the spring 21 is transmitted to the bolt 14. After the bolt 14 is pulled out, the L-shaped rod 19 is clamped in the L-shaped groove 18 by rotating the bolt 14, thereby achieving temporary locking of the bolt 14, without having to continuously pull the bolt 14, which facilitates the installation or disassembly of the manipulator main body 1. The arc-shaped groove 17 is used for providing a sliding track for the L-shaped rod 19 when the bolt 14 is rotated. The spring 21 is used for preventing the bolt 14 from moving without external force, thereby ensuring that the bolt 14 is tightly inserted into the T-shaped plug block 8.

[0036] Working principle: First, when the manipulator main body 1 is installed on the base 10, the bolt 14 is pulled out and rotated, so that the L-shaped rod 19 on the bolt 14 is clamped into the L-shaped groove 18, thereby achieving temporary locking of the bolt 14 without continuously pulling the bolt 14. Then, the T-shaped plug block 8 on the outer side of the manipulator main body 1 is inserted into the fixed block 9, and then the bolt 14 is reversely rotated so that the L-shaped rod 19 freely slides in the L-shaped groove 18. Finally, the bolt 14 is released, and under the action of the spring 21, the bolt 14 is automatically inserted into the T-shaped plug block 8, thereby completing the installation and fixation of the manipulator main body 1. If the manipulator main body 1 needs to be disassembled, the bolt 14 is pulled out from the T-shaped plug block 8 by pulling the pull ring, and the bolt 14 is temporarily locked by rotating it, so that the manipulator main body 1 can be easily disassembled.

[0037] When the manipulator main body 1 needs to be positioned, the base 10 will slide along the slide rail 7 by starting the air cylinder 5. The cooperation of the limiting block 11 and the sliding groove 12 ensures the smooth sliding of the base 10. During the sliding process, the pointer 3 and the scale mark 2 on the workbench 6 can be combined to accurately move and position the manipulator main body 1, thereby improving the stability of the manipulator main body 1 in work and greatly improving the work efficiency.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
