[0052] Example 2:
[0053] A method for disassembling a tie rod, wherein the disassembly method is implemented using the aforementioned disassembly fixture, includes the following steps:
[0054] Step 1, fixing the tip 22 of the pull rod:
[0055] Based on the position and basic dimensions of the pull rod tip 22 of the pull rod to be disassembled, the position of the lower clamp 6 between the upright plates 7 is initially adjusted and fixed. Then, the pull rod tip 22 is placed on the lower clamp 6, and the upper clamp 8 is fixedly installed. The positioning bolt is passed through the insertion holes 10 on the upper clamp 8 and the lower clamp 6, and at the same time through the pull rod through hole 27, thereby fixing the angle of the pull rod tip 22.
[0056] Step 2, Installation of Jack 13:
[0057] Load jack 13 onto jack mounting base 14;
[0058] Step 3, fixing the pull rod body 28:
[0059] Based on the position of the jack 13, determine the installation position of the lever clamp mechanism, then fix the lever clamp mechanism on the lever body 28, and ensure that the piston rod of the jack 13 is in contact with the second flat jaw clamp 18 of the lever clamp mechanism.
[0060] Step 4, disassembly of the pull rod body 28:
[0061] Start the jack 13, and push the second flat jaw clamp 18 of the lever clamp mechanism through the piston rod of the jack 13. Then, the lever clamp mechanism drives the lever body 28 to rotate, thereby causing the lever body 28 and the lever tip 22 to rotate relative to each other, and finally achieving the disassembly of the two.
[0062] Step 5, disassembly of the lever clamp mechanism:
[0063] After the pull rod tip 22 and the pull rod body 28 have been completely disassembled, the corresponding pull rod clamp mechanism is disassembled and the pull rod body 28 is removed.
[0064] Step 6, disassembly of the tip 22 of the pull rod:
[0065] After the tip 22 of the pull rod is disassembled, remove the positioning bolt, upper clamp 8 and lower clamp 6, and then disassemble the tip 22 of the pull rod.
