In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
The disassembly tool of the coupling of fig. 1 comprises: cover plate 10, oil chamber steel jacket 20, expansion outer ring 30, a plurality of top blocks 40, a plurality of first pads 50, tooling bottom plate 70, second pads 80, and retaining ring 60. The oil cavity steel sleeve 20 is of a stepped annular structure, the expansion outer ring 30 is of an annular structure with a C-shaped cross section, the expansion outer ring 30 is sleeved on the oil cavity steel sleeve 20, the expansion outer ring 30 and the oil cavity steel sleeve 20 form an annular cylinder structure and form an oiling cavity, the positioning ring 60 is sleeved on the oil cavity steel sleeve 20, the plurality of top blocks 40 are sequentially connected and encircle the oil cavity steel sleeve 20, and the positioning ring 60 is abutted with the top blocks 40 and supports the top blocks 40; the cover plate 10 is covered on the oil cavity steel sleeve 20 and the expansion outer ring 30, and the cover plate 10 is connected with the oil cavity steel sleeve 20. The first pads 50 are placed around the upper end surface of the positioning ring 60 one by one to supplement the height of the positioning ring 60.
The tool bottom plate 70 is connected with the positioning ring 60 and supports the positioning ring 60, and the second cushion block 80 is placed around the tool bottom plate 70 and used for supporting a coupling.
An oil filling hole is formed in the oil cavity steel sleeve 20 and is communicated with the oil filling cavity; an oil guide hole is formed in the cover plate 10, and the oil guide hole is communicated with the oil injection hole. The wall thickness D2 of the oil cavity steel sleeve 20 is 10-100 times of the wall thickness D1 of the expansion outer ring 30 so as to prevent cracking under high pressure; the thickness D3 of the cover plate 10 is 10-100 times the wall thickness D1 of the expansion outer ring 30 to protect the expansion outer ring 30 and prevent oil leakage. Specifically, the wall thickness D1 of the oil chamber steel sleeve 20 refers to the wall thickness of the portion of the oil chamber steel sleeve 20 sleeved with the expansion outer ring 30, and this portion of the oil chamber steel sleeve is connected with the expansion outer ring and forms the oil filling cavity, so that high pressure oil directly acts on this portion of the oil chamber steel sleeve and causes the oil chamber steel sleeve to expand. As shown in fig. 1, when the wall thickness D2 of the oil chamber steel sleeve 20 is several times the wall thickness D1 of the expansion outer ring 30, the expansion deformation of the oil chamber steel sleeve is far smaller than the deformation of the expansion outer ring under the same pressure, so that the expansion of the whole coupling towards the axial line outwards can be ensured.
The section of the positioning ring 60 is a step-shaped cylinder in a shape of a Chinese character 'yang', and the oil cavity steel sleeve 20 is sleeved in the positioning ring 60 and is abutted against the step surface of the positioning ring 60.
The top block 40 is a column with a convex section, and the top surface and the bottom surface of the convex column are both arc surfaces; the two "male" shaped top blocks 40 are joined and have a recess formed in the middle for receiving the spring plate 92 of the coupling.

The high-pressure pump is connected with the oil guide hole, high-pressure oil is led into the oil guide hole, and then the high-pressure oil flows through the oil guide hole from the oil guide hole and finally enters the oil injection cavity. The high-pressure oil is continuously pressurized to continuously increase the oil pressure in the oil injection cavity, the oil pressure is increased to expand the expansion outer ring 30 and the oil cavity steel sleeve 20, the wall thickness of the expansion outer ring 30 is thinner, and the expansion amount is obviously larger than that of the oil cavity steel sleeve 20; during the expansion of the expansion outer ring 30, the cover plate 10 presses the expansion outer ring 30 and prevents oil in the expansion outer ring 30 from leaking. The expansion outer ring 30 expands and deforms and presses the top block 40 to expand, and the top block 40 expands to expand the fixing block 94. The fixed block 94 expands, eventually expanding the outer ring 91 of the coupling, so that the whole coupling (except the spring piece) is expanded out of round, and the whole coupling swells. In the expansion process, the spring piece 92 is not deformed, so that the spring piece 92 is easily taken out through magnetic attraction, and the taken-out spring piece 92 is complete and can be reused.
In the whole hydraulic expansion process, the centering accuracy of the structure is kept, so that the pressure intensity in all directions along the axial line is consistent, and the stress of each fixed block 94 is balanced; and the centering effect therein is greatly dependent on the placement of the retaining ring 60.
The disassembly tool for the coupling can ensure that the spring piece 92 is not deformed or damaged when the coupling is disassembled, and the integrity of the spring piece 92 is ensured to a greater extent. And the disassembly process is simple, and the coupling is convenient to connect with the disassembly tool.
The disassembly method of the coupling is characterized in that the disassembly tool of the coupling is arranged;
the plurality of top blocks 40 are placed on the outer wall of the expansion outer ring 30 one by one, the coupling is sleeved on an annular structure surrounded by the plurality of top blocks 40, and the positioning ring 60 is placed between the expansion outer ring 30 and the coupling, and the positioning ring 60 is used for guaranteeing the centering of the coupling;
high-pressure oil is injected into the oil injection cavity through the oil injection hole, the pressurization is continued, the top block 40 expands, the fixed block 94 is expanded greatly by the convex part of the top block 40, and a sufficient gap is left in the concave part of the top block 40 and the spring piece 92 is not contacted during expansion.
When the fixed block 94 is inflated to generate a certain gap between the fixed block 94 and the spring piece 92 and the gap reaches 1 mm-1.5 mm, the pressurizing in the oiling cavity is stopped; the spring plate 92 is then removed by magnetic attraction. The expansion outer ring 30 is depressurized after the spring plate 92 is removed.
The disassembly method of the coupling can be completed by using the disassembly tool, so that the disassembly safety and the structural integrity during disassembly are improved.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
