Description

Technical Field

[0001] The utility model relates to the technical field of disassemblers, in particular to a disassembler for press-fit connection parts. Background Art

[0002] In order to increase the connection stability between the two mating parts, it is often necessary to press the two mating parts together with an interference fit to obtain greater fatigue resistance and increase the service life of the mating parts. However, during later maintenance and repairs, maintenance personnel have to spend a long time and energy to disassemble the equipment when repairing it.

[0003] The prior art publication number CN218476629U discloses a disassembler for press-fit connection parts, including a support rod, characterized in that a block adjustment rod is plugged into one end of the support rod through an opening, a limiting block 1 is welded to the bottom end of the block adjustment rod, a block is vertically plugged into the bottom end of the limiting block 1, a push rod adjustment rod is plugged into the other end of the support rod through an opening, a limiting block 2 is welded to the bottom end of the push rod adjustment rod, and a push rod is inserted through a thread at the bottom end of the limiting block 2;

[0004] When in use, the position of the block and the push rod can be adjusted by vertically installing the block adjusting rod and the push rod adjusting rod on the support rod respectively, so as to facilitate placing the push rod in the center of the press fitting and reduce the loss of force applied during separation. However, the block adjusting rod and the push rod adjusting rod are adjusted and positioned by cooperation of the positioning screws and positioning holes, and there is a certain distance between adjacent positioning holes, that is, the position of the block and the push rod cannot be accurately adjusted. In this way, there may be position errors during disassembly, which reduces the disassembly effect. Therefore, it is necessary to design a disassembler for press-fit connection parts to solve the above problems. Utility Model Content
