[0019] Referring to Figures 1-4 The utility model provides an embodiment: a kind of outer ring press fitting tool for triple joint processing, including support table 1, installation frame 4 is equipped on the support table 1, and hydraulic jack 3 is equipped in the installation frame 4;The hydraulic jack 3 is connected with the hydraulic station 2 equipped in the bottom of the support table 1 by oil pipeline;One side of the support table 1 is also equipped with mounting seat 9, and the mounting seat 9 is movably installed on the support table 1;The working end of the hydraulic jack 3 is connected with the top pipe 8 equipped by being equipped with first stud 10.

[0020] As described above, since the hydraulic jack 3 promotes the movement of the outer ring to the directional shaft of the triple joint, firstly, the press fitting of the outer ring does not require manual knocking, and the installation frame 4 guides the movement of the outer ring, so that the phenomenon of falling off between the outer ring and the directional shaft during installation can be effectively solved;Secondly, the pushing force of the hydraulic jack 3 is large, and the movement speed is relatively stable, so that the outer ring can be stably and directionally moved to the directional shaft, so that the phenomenon of misassembly caused by uneven manual knocking force can be solved, especially, the hydraulic jack 3 can stably promote the movement of the outer ring, so that the smooth assembly of the outer ring and the directional shaft can be ensured, and the assembly efficiency of the outer ring can be improved.

[0021] In addition, since the top pipe 8 is pushed on the outer ring, and then the top pipe 8 is connected with the first stud 10, so that the distance between the top pipe 8 can be selected according to the diameter of the outer ring. At the same time, the mounting seat 9 is movably installed on the support table 1, so that the replacement of the mounting seat 9 is simple and convenient, and then different sizes of mounting seat 9 are replaced to adapt to the size change of the triple joint.

[0022] Specifically, the mounting seat 9 comprises a support part 91; the upper portion of the support part 91 is inserted into the three-pronged joint through the provided stand column 90, and the lower portion of the support part 91 is connected with the provided first nut 14 through the provided screw rod 92 after passing through the support table 1. Therefore, the mounting seat 9 and the support table 1 can be disassembled by disassembling the first nut 14, and vice versa, the mounting seat 9 can be fixed on the support table 1, and the stand column 90 is inserted into the three-pronged joint to improve the stability of the three-pronged joint during the pressure process.

[0023] Further, the support part 91 is further provided with a limiting part 93, and the limiting part 93 is connected with the limiting groove 7 provided on the support table 1. Specifically, the limiting groove 7 is consistent with the cross section of the limiting part 93; wherein the cross section of the limiting part 93 is rectangular, and the thickness of the limiting part 93 is less than or equal to the thickness of the surface of the support table 1.

[0024] Therefore, the limiting groove 7 and the limiting part 93 are matched to avoid the axial rotation of the mounting seat 9 during work.

[0025] On the basis of the above-mentioned scheme, the inside of the mounting frame 4 is provided with a bracket 6, and the bracket 6 is connected with the provided pressure ring 11 to fix the hydraulic jack 3 in the mounting frame 4. Further, the bottom of the hydraulic jack 3 is threadedly matched with the provided second nut 12 after passing through the mounting frame 4 through the provided second stud 13.

[0026] Therefore, the hydraulic jack 3 can be taken down by disassembling the second nut 12 and the pressure ring 11, and vice versa, the position of the hydraulic jack 3 can be locked by the second nut 12 and the pressure ring 11. Therefore, the assembly of the outer ring and the directional shaft can be affected by the displacement of the hydraulic jack 3 during work.

[0027] In addition, since the support table 1 is further provided with the control box 5, the extension or shortening of the hydraulic jack 3 can be realized through the control box 5, for example, when the opening button on the control box 5 is pressed, the hydraulic station 2 pumps the hydraulic oil from the bottom of the hydraulic jack 3 to make the hydraulic jack 3 extend; when the closing button is pressed, the hydraulic station 2 pumps the hydraulic oil from the upper portion of the hydraulic jack 3 to make the hydraulic jack 3 shorten. Therefore, the user can realize the extension or shortening of the hydraulic jack 3 through the control box 5, which facilitates the smooth assembly of the outer ring and improves the assembly efficiency of the outer ring.

[0028] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments.
