Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
A copper bush mounting tool as shown in fig. 1-3, comprising a base 1, a bolt 2 and a positioning block 3;
the base 1 includes a bottom plate 11, a side wall 12 and a center pillar 13,
the bottom plate 11 is a circular plate, the side wall 12 surrounds the circular edge of the bottom plate 11 and is perpendicular to the bottom plate 11, the center pillar 13 is located at the center of the bottom plate 11, and a circular groove space 100 is formed among the bottom plate 11, the side wall 12 and the center pillar 13;
the side wall 12 is provided with a plurality of threaded holes 121; the bolt 2 is matched with the threaded hole 121, and the bolt 2 is divided into an extrusion end 21, a threaded section 22 and a force application end 23; the extrusion end 21 is located on the inner side of the side wall 12, the thread section 22 is matched with the threaded hole 121, the force application end 23 is located on the outer side of the side wall 12, and the force application end 23 is provided with a structure capable of bearing the action of external force;
the positioning block 3 is located on the bottom plate 11, and is a component protruding from the bottom plate 11 for positioning.
Referring to fig. 1, the mounting ring 4 is nested on the center pillar 1, the copper bush 5 to be assembled is nested on the piston 6, the piston 6 is inserted into the mounting hole 42 of the mounting ring 4, because the mounting hole 42 of the mounting ring 4 is aligned with the bolt 2 after the limiting hole 41 of the mounting ring 4 is engaged with the positioning block 3, and the copper bush 5 can be embedded into the mounting ring 4 by rotating the bolt 2. As shown in fig. 1, when the copper bush 5 is pushed against the center pillar 1, the copper bush 5 is fitted in place. Because the copper bush 5 is evenly stressed in the whole process, obvious deformation cannot be generated, and the product quality is not influenced. The installation depth of the copper sleeves 5 is limited by the central column 1, and the embedding depth of all the copper sleeves 5 is guaranteed to be consistent. Because the distance between each grade of screw tooth of screw is very little, can be fine hold copper sheathing 5 have or not appear off-centre inlaying the in-process, can repeatedly look over moreover whether smooth and easy with the cooperation between copper sheathing 5 and piston 6.
More specifically, the bottom plate 11 is provided with a screw hole 111, and the positioning block 3 is screwed with the screw hole of the bottom plate 11 and fixed on the bottom plate 11.
After the mounting ring 4 is mounted on the base 1, the mounting ring 4 is tightly fitted with the positioning block 3 due to possible tolerance of the workpiece, so that the assembled mounting ring 4 is inconvenient to take out. At this time, the positioning block 3 is pulled out from the bottom plate 11, and the mounting ring 4 can be easily taken out.
To explain further, the center pillar 1 is screw-mounted on the upper side of the bottom plate 11.
The king-post 1 can be replaced to accommodate mounting rings 4 of different inner diameters.
In a further illustration, the force application end 23 is a hexagonal nut or a square nut or a torsion bar.
The great force required to squeeze the copper bush 5 into the mounting ring 4, and the hexagonal nut shown in fig. 5 can provide a force application point, which facilitates the installation of the copper bush 5 by other external forces.
The method for using the copper bush installation tool comprises the following steps:
the method comprises the following steps: nesting a mounting ring 4 on the center post 13, placing the mounting ring in the slot space 100, aligning the mounting ring with the locating block 3, and ensuring that the mounting holes 42 of the mounting ring 4 are aligned with each threaded hole 121;
step two: mounting the bolt 2 to the threaded hole 121;
step three: the piston 6 is nested into the copper sleeve 5 to be assembled. The piston 6 comprises a plug-in end 61, a clamping ring 62 and a tail end 63, wherein the clamping ring 62 surrounds the joint of the plug-in end 61 and the tail end 63, the clamping ring 62 is of an annular structure with the outer diameter larger than that of the copper bush 5 and can be clamped at one end of the copper bush 5, and the outer diameter of the plug-in end 61 is smaller than the inner diameter of the copper bush 5;
step four: aligning the piston 6 and the copper sleeve 5 nested together with the mounting hole 42 on the mounting ring 4, and plugging the plugging end 61 into the mounting hole 42;
step five: the bolt 2 is rotated so that the pressing end 21 of the bolt 2 abuts against the rear end 63 of the piston 6, and the insertion end 61 of the piston 6 is pushed until the center pillar 1 cannot advance.
Aligning the mounting hole 42 of the mounting ring 4 with the threaded hole 121 ensures that the bolt 2 is used to push the copper bush 5 into the mounting ring 4 centrally. When the bolt 2 is used for pushing the copper sleeve 5, the tail end 63 is stressed, and meanwhile, the clamping ring 62 is clamped at one end of the copper sleeve 5, so that the copper sleeve 5 is driven to enter the mounting hole 42 of the mounting ring 4 together. In the piston 6 without the snap ring 62, the cylindrical copper bush 5 does not receive the force receiving surface of the bolt 2, and cannot be pushed into the mounting hole 42 of the mounting ring 4 by the bolt 2. The plugging end 61 of the piston 6 is pushed until the center pillar 1 can not advance, thereby ensuring that all the installed copper sleeves 5 have the same depth.
In a further elaboration, the piston 6 has a plug-in end 61 that protrudes beyond the copper jacket 5.
Because the outer diameter of the plugging end 61 of the piston 6 is smaller than that of the copper bush 5, the piston 6 is easier to plug into the mounting hole 42, and the plugging end 61, which is longer than the copper bush 5, of the piston 6 can be plugged into the mounting hole 42 to temporarily fix the piston 6 and the copper bush 5 in the mounting hole 42, so that the bolt 2 can exert force to push the piston 6 into the mounting hole 42.
In further illustration, the stuffing end 61 of the piston 6 is ellipsoidal.
The tucking end 61 of the piston 6 as shown in fig. 7 is ellipsoidal and therefore more easily fits into a circular hole, facilitating the tucking of the piston 6 into the mounting hole 42 in the mounting ring 4 and also facilitating the nesting of the piston 6 into the copper shell 5.
Stated further, the piston 6 is in close fit with the copper sleeve 5.
The piston 6 and the copper bush 5 which are tightly matched can be tightly wedged together, and the phenomenon that a gap exists between the piston 6 and the copper bush 5 due to machining errors is prevented.
In a further description, in the third step, when the piston 6 and the copper bush 5 are eccentric, the bolt 2 stops rotating, the piston 6 is adjusted, and the bolt 2 continues to rotate.
Because if the copper bush 5 becomes eccentric during the advancing process, the copper bush 5 will be damaged by the further advancing. The position of the piston 6 is adjusted in time to ensure the centering of the piston, and the damage of the copper sleeve 5 and the piston gas ring 4 can be effectively avoided.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be taken in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
