[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please refer to Figures 1-5. This invention provides a technical solution: an automatic disassembly and assembly device for work roll bearing seats, including a trolley base 10. A trolley linear guide rail 9 is provided on the upper surface of the trolley base 10. A roll traversing carriage 3 is slidably arranged on the trolley linear guide rail 9. A work roll 1 is placed on the roll traversing carriage 3. Work roll bearing seats 2 are installed at both ends of the work roll 1. A trolley drive mechanism is installed on the trolley base 10 to drive the roll traversing carriage 3 to move along the trolley linear guide rail 9. Automatic disassembly and assembly structures for disassembling and assembling the work roll bearing seats 2 are symmetrically arranged on both sides of the trolley base 10. Driven by the trolley drive mechanism, the roll traversing carriage 3 moves on the trolley base 10, moving the work roll 1 to the automatic disassembly and assembly structure. The automatic disassembly and assembly structure disassembles and assembles the work roll bearing seats 2, replacing the traditional manual disassembly and assembly work, reducing the labor intensity of workers, greatly improving the efficiency of disassembling and assembling bearing seats, reducing the workload, and eliminating the installation hazards in the manual disassembly and assembly process, thus ensuring production safety.

[0022] One specific technical solution involves a trolley drive mechanism comprising a trolley servo motor reducer 4 mounted on the side surface of the trolley base 10. The output shaft axis of the trolley servo motor reducer 4 is parallel to the trolley linear guide rail 9. Three fixed frames are evenly arranged on the trolley base 10. The trolley servo motor reducer 4 is mounted on the side surface of one of the fixed frames. The output shaft of the trolley servo motor reducer 4 passes through this fixed frame and is connected to the trolley ball screw 8 via a coupling. An intermediate bearing seat 11 is mounted on the middle fixed frame, and a trolley bearing seat 5 is respectively mounted on the fixed frames at both ends. The trolley ball screw 8 is connected to the intermediate bearing seat 11 and the trolley bearing seat 5 respectively. Forks are respectively mounted on the trolley ball screw 8. Head I7 and fork II12 are respectively located on both sides of the intermediate bearing seat 11, and each fork I7 and fork II12 is provided with a ball screw nut I6 that is threadedly connected to the main carriage ball screw 8. The roll traversing carriage 3 is fixedly installed between fork I7 and fork II12. The main carriage servo motor reducer 4 drives the main carriage ball screw 8 to rotate, thereby causing the two ball screw nuts I6 to drive fork I7 and fork II12 to move along the main carriage ball screw 8, and then drive the roll traversing carriage 3 to move along the X-axis direction, moving the work roll 1 to the disassembly and assembly station for automatic disassembly and assembly. The system adopts servo motor and ball screw transmission, and the centering method uses servo motor control, which is simple to operate and precise to control.

[0023] One specific technical solution is that the automatic disassembly and assembly structure includes trolley bases 26 symmetrically arranged on both sides of the main carriage base 10 and disassembly and assembly trolleys 19 arranged on the trolley bases 26. The trolley bases 26 are provided with disassembly and assembly trolley linear guide rails 16, and the disassembly and assembly trolleys 19 are slidably arranged on the disassembly and assembly trolley linear guide rails 16. The disassembly and assembly trolley linear guide rails 16 are perpendicular to the main carriage linear guide rails 9. The trolley bases 26 are provided with trolley drive mechanisms. Each of the four corners of the upper surface of the disassembly and assembly trolley 19 is provided with a sleeve 20, and a guide rod 21 is slidably arranged inside the sleeve 20. The top of the guide rod 21 is provided with an upper cover plate 25. The four sleeves 20 and the guide rods 21 are used to support and balance the upper cover plate 25 and keep it horizontal, so as to prevent it from tilting during the disassembly and assembly of the work roller bearing seat 2, which would make it difficult to disassemble or misaligned during installation.

[0024] The upper surface of the disassembly and assembly trolley 19 is equipped with a ball bearing lifter 22 and a disassembly and assembly trolley servo motor 23 connected to the ball bearing lifter 22. The upper surface of the upper cover plate 25 is provided with a positioning pin 24 corresponding to the work roller bearing seat 2. The ball bearing lifter 22 and the disassembly and assembly trolley servo motor 23 drive the upper cover plate 25 to move up and down in the Y-axis direction, thereby completing the vertical alignment of the work roller and the bearing seat, so that the positioning pin 24 cooperates with the positioning hole on the work roller bearing seat 2, thereby completing the disassembly or assembly of the work roller bearing seat 2.

[0025] In a preferred embodiment, four or more sets of trolley bases 26 and disassembly / assembly trolleys 19 are provided. Two or more sets of trolley bases 26 and disassembly / assembly trolleys 19 are provided on both sides of the main trolley base 10. The spacing between adjacent sets of trolley bases 26 and disassembly / assembly trolleys 19 is the same as the spacing placed on the roll transverse carriage 3, thereby enabling the simultaneous disassembly and assembly of work roll bearing seats 2 on multiple work rolls 1, further improving work efficiency.

[0026] One specific technical solution involves a trolley drive mechanism comprising a trolley servo motor reducer 13 mounted on a trolley base 26. The output shaft of the trolley servo motor reducer 13 is parallel to the linear guide rail 16 of the disassembly / assembly trolley. Two trolley bearing seats 14 are symmetrically mounted on the trolley base 26. The output shaft of the trolley servo motor reducer 13 is connected to a disassembly / assembly trolley lead screw 15 via a coupling. The disassembly / assembly trolley lead screw 15 is rotatably positioned between the two trolley bearing seats 14, and two disassembly / assembly forks 18 are mounted on the disassembly / assembly trolley lead screw 15. Each of the disassembly and assembly fork heads 18 is provided with a ball screw nut II 17 threadedly connected to a disassembly and assembly trolley screw 15. The disassembly and assembly trolley 19 is fixedly installed between the two disassembly and assembly fork heads 18. The trolley servo motor decelerator 13 drives the disassembly and assembly trolley screw 15 to rotate, thereby causing the two ball screw nuts II 17 to drive the two disassembly and assembly fork heads 18 to move along the disassembly and assembly trolley screw 15, so that the disassembly and assembly trolley 19 moves in the Z-axis direction, so as to move and install the work roller bearing seat 2 on the upper cover plate 25 onto the work roller 1 or remove the work roller bearing seat 2 that needs to be replaced from the work roller 1.

[0027] In a preferred embodiment, a fixed base 27 is installed on the outer surface of the trolley base 10. A linear guide module 28 is provided on the fixed base 27. A displacement sensor 29 for detecting the center height of the work roller 1 is installed on the movable end of the linear guide module 28. The center height of the work roller can be detected by the displacement sensor 29, thereby automatically and accurately controlling the lifting height of the upper cover plate 25 by an external controller, further improving the automation level of the disassembly and assembly of the work roller bearing seat 2.

[0028] In a further preferred embodiment, three displacement sensors 29 are provided, and the three displacement sensors 29 are arranged at equal distances. The two displacement sensors 29 on both sides are symmetrically arranged on both sides of the middle displacement sensor 29. When detecting the center height of the work roller, since the work roller is cylindrical, it is not easy to accurately detect its center position. Therefore, three displacement sensors 29 are set for detection. During the detection process, when the heights detected by the two displacement sensors 29 on both sides are consistent, it can be determined that the position of the middle displacement sensor 29 is at the center of the work roller, which can further improve the accuracy and precision of the disassembly and assembly work.

[0029] An optional technical solution is that several sets of V-shaped frames are symmetrically arranged on both sides of the upper surface of the roll transverse carriage 3. The working roll 1 is placed on the V-shaped frame, and the axis of the working roll 1 is perpendicular to the linear guide rail 9 of the trolley. The V-shaped frame is made of rigid polyurethane board (nylon board) to avoid damage to the roll during disassembly and assembly.

[0030] Furthermore, the inner surface of the V-shaped frame is provided with a buffer pad, which can be made of rubber or the like. The buffer pad can provide buffer protection for the work roller 1 and increase friction, making the work roller 1 more stable during the assembly and disassembly of the work roller bearing seat 2.

[0031] All parts not disclosed in this invention are prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
