Description

Technical Field

[0001] This utility model relates to the field of expansion sleeve disassembly technology, specifically to a disassembly device for expansion sleeves. Background Technology

[0002] After the expansion sleeve is installed on the bearing, it can tightly clamp the bearing and the rotating shaft together. Since the central shaft is long and the bearing cannot be placed horizontally or vertically, it is not convenient to disassemble manually. Thus, the use of disassembly equipment gradually developed.

[0003] In existing technology, disassembling the expansion sleeve involves holding the bearing with one hand and using a hex wrench with the other to loosen its screws, then sliding it off. However, manually removing the disassembly device is not only time-consuming but also causes oil stains from the bearing to stick to one's clothes. Therefore, this invention proposes a disassembly device for the expansion sleeve to solve the above problems. Utility Model Content

[0023] Example 1

[0024] Please see Figure 1 , Figure 2 and Figure 5 This utility model provides a technical solution: a disassembly device for a tightening sleeve, comprising: a base plate 1, a robotic arm device 2 and a fixing device 3 disposed on the upper part of the base plate 1, a mechanical handle for disassembling screws, and a fixing device 3 for fixing components before disassembly. The robotic arm device 2 includes a base 4, a robotic arm 5, a mounting box 8, a camera 7, a first motor 9, and a wrench assembly 6. The base 4 is fixedly mounted on the upper surface of the base plate 1. The base 4 has a complex mechanical structure and an integrated circuit board inside. The integrated circuit inside the base 4 has a main control chip that controls the entire workflow of the device. Multiple robotic arms 5 are disposed above the base 4. The mechanical handles can rotate freely in all directions. The mounting box 8 is disposed at one end of the uppermost mechanical wall. The mounting box 8 has a vision processing module and a certain mechanical structure inside. Two cameras 7 are disposed on the lower surface of the mounting box 8. The cameras 7 are used to capture images and determine positions. The first motor 9 is disposed on the upper surface of the mounting box 8. The output end of the first motor 9 passes through the mounting box 8 and is rotatably connected to it. The wrench assembly 6 is disposed at the output end of the first motor 9 and is mainly used for disassembling screws.

[0025] The wrench assembly 6 includes a connecting post 29 and a hexagonal wrench 32. The connecting post 29 is fixedly installed at the output end of the motor and mainly serves as a transmission and connection mechanism. The connecting post 29 is a hexagonal prism with a hexagonal groove 30 at its bottom. The hexagonal wrench 32 is slidably connected within the hexagonal groove 30. Thus, rotation of the connecting post 29 will drive rotation of the hexagonal wrench 32. A spring 31 is fixedly installed on the upper surface of the hexagonal wrench 32. One end of the spring 31 is fixedly connected to the upper surface of the hexagonal wrench 32, and the other end of the spring 31 is fixedly connected to the top wall of the hexagonal groove 30. The spring 31 allows the hexagonal wrench 32 to extend and retract within the hexagonal groove 30.

[0026] Once the robotic arm visually identifies the screw, it can clearly recognize the hexagonal hole. This allows for the accurate insertion of a hex wrench into the hole. During the insertion of the hex wrench 32, the spring 31 is slightly compressed. Then, the first motor 9 is activated, which drives the connecting post 29 to rotate. The connecting post 29, in turn, drives the hex wrench 32 to rotate, which in turn causes the screw to rotate. During this rotation, the spring 31 is compressed, thus disengaging the screw from its original hole.

[0027] Example 2

[0028] Please see Figures 1-4 Based on Embodiment 1, the fixing device 3 includes a fixing block 10, a driving device 11, a first push rod 18, a lifting column 16, and a clamping dish 12. The fixing block 10 is fixedly installed on the upper surface of the base plate 1. The driving device 11 is disposed on the fixing block 10 and embedded in the fixing block 10. Several first push rods 18 are respectively disposed on each side of the fixing block 10. The output end of the electric push rod extends through the fixing block 10 and is slidably connected to it. Several lifting columns 16 are fixedly installed on the output ends of several first push rods 18, that is, each electric push rod output end is equipped with a lifting column 16. The top of several lifting columns 16 is fixedly installed with a clamping dish 12. Thus, the lifting and lowering of the output end of the first push rod 18 can drive the lifting and lowering of the clamping dish 12.

[0029] The driving device 11 includes a second motor 28, a rotating column 20, a second push rod 21, and a lifting dish 22. The rotating column 20 is embedded in and rotatably connected to the fixed block 10, and can rotate within the fixed block 10. The second motor 28 is located below the rotating column 20 and is also embedded in the fixed block 10. The output end of the second motor 28 can drive the rotating column 20 to rotate. The second push rod 21 is embedded in the rotating column 20. The lifting dish 22 is fixedly installed at the output end of the second push rod 21, and the central rotating shaft can be fixed within the lifting dish 22. Thus, the lifting and lowering of the output end of the second push rod 21 can drive the lifting and lowering of the lifting dish 22, and at the same time, can drive the lifting and lowering of the central rotating shaft to be disassembled.

[0030] A second annular block 25 is slidably connected inside the lifting dish 22, and a first annular block 24 is slidably connected inside the second annular block 25. The upper surfaces of the first annular block 24, the second annular block 25, and the lifting dish 22 are flush. The side walls of the lifting dish 22, the first annular block 24, and the second annular block 25 are all provided with second through holes 26. The second through holes 26 of the three are aligned. A threaded pin passes through multiple second through holes 26 and is threadedly connected to them. The threaded pin can be inserted into the center of the first annular block 24, the center of the second annular block 25, or the center post inside the lifting dish 22. In this way, the bearing and the expansion sleeve can be horizontally fixed inside the clamping dish 12. A first through hole 15 is provided at the bottom of the clamping dish 12. The size of the first through hole 15 is the same as the outer diameter of the second annular block 25. Multiple first screws 13 are provided on the side wall of the clamping dish 12. The multiple first screws 13 can fix the bearing that is horizontally placed inside the clamping dish 12, thus fixing it.

[0031] In actual use, the expansion sleeve with bearing and central shaft needs to be fixed. One end of the central shaft is inserted into the first through hole 15. Then, the second push rod 21 is activated to place the central shaft in the lifting dish 22. The appropriate first annular block 24 or second annular block 25 is selected according to its diameter. Then, the output end of the second push rod 21 is lowered and the output end of the first push rod 18 is raised until the central column and the bottom of the lifting dish 22 have almost no pressure. When the bearing and expansion block are placed horizontally in the clamping dish 12, the central shaft in the lifting dish 22 is fixed with screws. Then, the bearing in the clamping dish 12 is fixed. Then, the robotic arm 5 is activated to disassemble through visual processing. During the disassembly process, the second motor 28 will rotate to prevent the robotic arm 5 from touching the central shaft.

[0032] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
