[0003] High-torque intelligent servo tightening shafts are key equipment in modern intelligent manufacturing. Through the perfect combination of servo motors, high-precision sensors, and intelligent algorithms, they achieve a unity of "power and precision," upgrading the traditional "feel-based" tightening operation to a digital, controllable, and traceable precision process. This significantly improves product quality and production efficiency, making it a standard configuration for smart factories in the Industry 4.0 era. The servo motor receives commands from the controller, outputs rotational power, increases torque through a reducer, and transmits it to the bolt / nut through the tightening shaft to achieve fastening.

However, this requires the use of professional disassembly and assembly tools to disassemble and assemble the screws, and then disassemble and replace the flexible coupling, making the replacement process quite cumbersome. Therefore, a fixed intelligent tightening shaft is proposed to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figures 1-3This utility model provides an embodiment of a fixed intelligent tightening shaft, including a servo motor 1 and a reducer 3. The reducer 3 is fixedly connected to the bottom outer wall of the servo motor 1. The servo motor 1 is an imported Japanese Yaskawa servo motor 1, ensuring higher power output and more mature control. The reducer 3 uses a high-speed precision planetary reducer APEX-AB type, which has better stability and service life, providing effective assurance for tightening quality. A sensor outlet 4 is fixedly connected to the left outer wall of the reducer 3. A force sensor 5 is fixedly connected to the bottom inside of the reducer 3. The force sensor 5 has a high resolution of 0.001NM and a range of up to 5000NM. A power output square shaft 6 is fixedly connected to the output end of the servo motor 1. The power output square shaft 6 is made of high-strength alloy steel, providing more stable operation and a longer service life. It also supports flexible assembly and use with various specifications of couplings, with quick disassembly and assembly and stable operation. The side outer wall of the power output square shaft 6 contacts an elastic coupling 7, which can improve... The system provides flexible couplings 7 in various specifications, models, and sizes. An assembly mechanism 8 is provided on the reducer 3, and an adjustment mechanism 9 is provided on the servo motor 1. The assembly mechanism 8 includes an inner groove 81, which is located on the front inner wall of the reducer 3. A movable plate 82 is slidably connected to the front inner wall of the inner groove 81. A clamping plate 83 is fixedly connected to the left outer wall of the movable plate 82. The clamping plate 83 engages with a positioning frame 84 to fix and limit the flexible coupling 7, preventing axial displacement or detachment during tightening. A positioning frame 84 is clamped to the side outer wall of the clamping plate 83. A concave-convex plate 85 is fixedly connected to the top outer wall of the movable plate 82. An indicator mark 86 is fixedly connected to the top outer wall of the concave-convex plate 85. The indicator mark 86 clearly indicates the pushing direction of the movable plate 82 through a prominent display coating, helping operators quickly master the operating procedures, reducing misoperation, and further improving the replacement efficiency of the flexible coupling 7. A compression spring 87 is fixedly connected to the right outer wall of the movable plate 82.
[0019] Reference Figures 2-4 The power output square shaft 6 passes through the bottom inner wall of the reducer 3. The positioning frame 84 is fixedly connected to the top outer wall of the elastic coupling 7. The positioning frame 84 passes through the bottom outer wall of the force sensor 5. A frosted sleeve is fixedly connected to the side outer wall of the concave-convex plate 85. The frosted sleeve fixedly connected to the side outer wall of the concave-convex plate 85 further increases the friction during operation and prevents the hand from slipping. The end of the compression spring 87 away from the movable plate 82 is fixedly connected to the right inner wall of the inner groove 81. A display coating is fixedly connected to the front outer wall of the indicator mark 86. The display coating, such as a fluorescent coating, can enhance the visibility of the indicator mark 86, so that the operator can quickly identify it even in a dimly lit working environment.
[0020] Reference Figures 3-4The adjustment mechanism 9 includes a cable combing frame 91, which is fixedly connected to the left outer wall of the servo motor 1. A combing opening 92 is provided on the top inner wall of the cable combing frame 91, extending through the upper and lower outer walls of the cable combing frame 91. This opening is used to centrally accommodate the data cables of components such as the servo motor 1 and the force sensor 5, preventing cables from being scattered around the equipment and reducing the risk of cable tangling. Sliding grooves 93 are provided on the left and right inner walls of the combing opening 92, and closing plates 94 are slidably connected to the left and right inner walls of the sliding grooves 93. The combing port 92 can be opened and closed by sliding along the groove 93. When closed, it can fix and limit the cable in the combing port 92 to prevent the cable from coming out of the combing port 92. The silicone sleeve on the side can buffer the contact pressure between the closing plate 94 and the cable. The combing port 92 passes through the bottom outer wall of the cable combing frame 91. The silicone sleeve is fixedly connected to the side outer wall of the closing plate 94. The left outer wall of the closing plate 94 is fixedly connected to the directional mark 95. The directional mark 95 indicates the sliding direction of the closing plate 94 and helps the operator to quickly complete the opening and closing operation of the combing port 92.
[0021] Working principle: When the flexible coupling 7 needs to be replaced, the convex-concave plate 85 is moved by observing the indicator mark 86. The movement of the convex-concave plate 85 drives the movable plate 82 to move, which in turn drives the clamping plate 83 to move. The clamping plate 83 moves and separates from the positioning frame 84. Then, the flexible coupling 7 is pulled to pull the positioning frame 84 out from the bottom inner wall of the force sensor 5. Then, the positioning frame 84 on the new specification flexible coupling 7 is inserted into the inner wall of the force sensor 5, so that the positioning frame 84 and the clamping plate 83 are engaged with each other, quickly completing the disassembly and assembly operation, saving replacement time and improving efficiency. At the same time, the data lines of each sensor are placed in the combing port 92. Then, the closing plate 94 is inserted into the slide groove 93 to organize the multiple lines and prevent them from being scattered around, which would affect the operation of the flexible coupling 7.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
