As shown in fig. 1 to 7, the present invention provides an automatic fastening device for a high-speed brake disc and a flange bolt, which includes a fixed rail system 1, a suspension system 2 suspended below the fixed rail system 1 and capable of moving along the fixed rail system 1, and a servo tightening system 3 connected to a lower end portion of the suspension system 2, wherein the servo tightening system 3 includes a box 301, a servo transmission module 302 disposed inside the box 301, a tightening shaft module 303 connected to the servo transmission module 302, a control touch screen module disposed outside the box 301, and an operating handle 305, the box 301 is provided at both ends thereof with inner end caps 3011, the inner end caps 3011 are provided with adjustable slide rails 3012, the servo transmission module 302 includes a servo motor 3021, the tightening shaft module 303 includes a nut sleeve rod 3031 connected to a motor output shaft of the servo motor 3021, and a connecting bolt 3032 connected to the nut sleeve rod 3031, and the servo transmission module 302 and the nut sleeve rod 3031 can slide along the adjustable slide rails 3012 through a slider 3016 to be capable of adapting to high-speed brake discs and flange bolts of different diameters.
The servo tightening system can be used for tightening bolts on a high-speed brake disc and a flange disc by adopting the servo tightening system 3, the working position and the working direction of the servo tightening system 3 are adjusted by the fixed track system 1 and the suspension system 2 connected with the fixed track system 1 before tightening, and the operation is more flexible. Meanwhile, it is conceivable that the high-speed brake disc and the flange disc are formed in a disc structure or a disc-like structure, the diameters of which are not completely uniform but are controlled within a certain range, and therefore, it is conceivable that the inner end covers 3011 at both ends of the casing 301 of the servo tightening system 3 of the present invention are provided with adjustable slide rails 3012, and the sliders 3016 are slidably connected along the adjustable slide rails 3012, so that the interconnected servo transmission module 302 and tightening shaft module 303 can be moved along the adjustable slide rails 3012, i.e., the central axis of each of the servo transmission module 302 and tightening shaft module 303 can be moved around the radial direction of the casing 3013. In the moving process, the diameter of a circle formed by enclosing the central axes of the servo transmission module 302 and the tightening shaft module 303 can be adjusted within a certain range, and after the adjustment is carried out according to actual use requirements, more use requirements can be met. The servo transmission modules 302 and the tightening shaft modules 303 can be arranged in a linkage relationship, that is, when one set of the servo transmission modules 302 and the tightening shaft modules 303 is adjusted, and the rest of the servo transmission modules 302 and the tightening shaft modules 303 move outwards or inwards correspondingly by the same distance, the servo transmission modules 302 and the tightening shaft modules 303 enclose circles with different diameters. If the servo transmission modules 302 and the tightening shaft module 303 are not in linkage relation and the tightening positions of the servo transmission modules 302 and the tightening shaft module 303 are separately arranged, the bolt tightening requirements of the special-shaped structure can be met, namely, the tightening requirements can be met when the bolts on the high-speed brake disc and the flange disc are enclosed into a non-circular structure. The servo tightening system 3 is also connected with a control touch screen module, controls the magnitude of the fastening torque value and feeds the fastening torque value back to the control touch screen module. When the servo tightening system 3 is installed at the lower end of the suspension system 2, the servo tightening system 3 can rotate, and the rotation angle of the servo tightening system 3 can be fed back to the control system.
Also, the servo transmission module 302 in the servo tightening system 3 is controllable and adjustable for the torque value applied to the tightening shaft module 303, and the applied torque value can also be fed back to the control system so that the applied torque value can be displayed and stored in a specific value. When the numerical value on each servo tightening system 3 is abnormal, the numerical value can be timely known by an operator, and the known torque value can be analyzed. Compared with a manual torque wrench, the servo tightening system 3 provided by the invention has the advantages that the force applied by the servo transmission module 302 is controllable through the control system, a feedback mechanism is formed on the applied torque value, and the applied torque value is stored, so that the requirements of tightening bolts with different thread diameters on different parts can be met, data during tightening of various bolts can be summarized, the different parts are tightened through the optimal torque value during tightening of the bolts, and the tightening effect is further improved.
The invention can adapt to circles with different diameters surrounded by the bolts, and the diameters of the circles surrounded by the installed bolts are different, so that the invention can adapt to the high-speed brake discs and the flange discs with different diameters.

The torque sensor 3022 is capable of transmitting an analog amount of the torque signal to the control system in real time. The servo motor 3021 is controlled by converting an electric pulse signal into an angular displacement or a linear displacement, and the servo motor normally operates at a high speed or a low speed without generating any vibration.

It is contemplated that the length of the support risers and the travel of the height adjustment mechanism 202 can affect the particular position of the suspension system 2 in the up-down direction during actual use.
More specifically, the height adjustment mechanism 202 is a cylinder or an oil cylinder. Of course, the height adjustment mechanism 202 of the present invention may be configured in other configurations, and the height adjustment mechanism can be configured to be height-adjustable for the servo tightening system 3, which falls within the protection scope of the present invention.
