Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, and in particular to a retaining ring mounting device. Background Technology

[0002] A discontinuous labyrinth ring is a sealing ring that utilizes multiple annular sealing teeth to form a discontinuous, tortuous path, thereby reducing media leakage. For example... Figure 2 As shown, the labyrinth ring (pressed-in part 20) has a shaft hole 201, and the retaining ring 10 needs to be pressed into the shaft hole 201 after the O-ring rubber pad is installed on the outside.

[0003] The existing assembly method relies on manual adjustment. Due to insufficient pressing force and uneven frictional resistance of the O-ring rubber pad, the retaining ring is prone to tilting after assembly, which in turn poses a risk of shearing and breaking of the retaining ring. Utility Model Content

[0004] The purpose of this utility model is to provide a retaining ring installation device that increases the pressing force during the pressing process and prevents the retaining ring from tilting after assembly.

[0005] The technical solution of this utility model is: a retaining ring mounting device, including a support, a pressure rod, a base, and a sliding rod. One end of the pressure rod is hinged to the support, and the other end of the pressure rod forms a force-bearing end. A platform is horizontally provided on the support. One end of the sliding rod is hinged to the pressure rod, and the other end of the sliding rod is provided with a first mounting end for placing the retaining ring. The base is located directly below the sliding rod, and the sliding rod is slidably connected to the platform, so that the first mounting end is vertically displaced relative to the base. The upper end of the base forms a second mounting end for placing the pressed-in part.

[0006] In the above solution, by setting a pressure bar with a force-bearing end, a support for providing support, and a slide bar for placing the retaining ring, it is only necessary to apply downward pressure to the force-bearing end to drive the first mounting end on the slide bar to move vertically downward, so that the retaining ring can be easily pressed in, increasing the pressing force during the pressing process, so that the O-ring rubber pad is compressed as a whole, and preventing the retaining ring from tilting after assembly.

[0007] Preferably, the support includes a base plate and a vertical plate connected to the base plate, the platform is horizontally connected to the vertical plate, the platform is located above the base plate, the slide rod is slidably connected to the platform, and the pressure rod is hinged to the vertical plate.

[0008] Preferably, the pressure rod includes a handle and a support rod hinged to the handle. One end of the handle is hinged to the support, the other end of the handle forms the force-bearing end, and the end of the support rod away from the handle is hinged to the slide rod.

[0009] Preferably, the slide bar includes a first shaft portion and a second shaft portion arranged sequentially. The first shaft portion is slidably connected to the support, the upper end of the first shaft portion is hinged to the pressure rod, and the outer surface of the second shaft portion forms a first mounting end.

[0010] Preferably, the diameter of the second shaft portion is larger than the diameter of the first shaft portion.

[0011] Preferably, the slide bar further includes a third shaft portion connected to the second shaft portion, the third shaft portion being disposed away from the first shaft portion, and the base having an inner hole adapted to the third shaft portion.

[0012] Preferably, the diameter of the third shaft portion is smaller than the diameter of the second shaft portion.

[0013] Compared with related technologies, the beneficial effects of this utility model are as follows: I. This utility model, by setting a pressure rod with a force-bearing end, a support for providing support, and a slide rod for placing the retaining ring, only requires applying downward pressure to the force-bearing end to drive the first mounting end on the slide rod to move down, which can easily press the retaining ring in, increase the pressing force during the pressing process, so that the O-ring rubber pad is pressed as a whole, and avoid the retaining ring tilting after assembly. Second, the sliding connection between the slide rod and the support in this utility model can ensure that the movement of the slide rod always remains vertical and that the retaining ring is accurately assembled. Third, the pressure bar of this utility model adopts a lever structure formed by the hinge of the handle and the support rod, which increases the force during the pressing process; Fourth, a third shaft is provided on the slide rod, and an inner hole is provided in the base. When assembling the retaining ring, the third shaft is first inserted into the inner hole to achieve center positioning and play a guiding role. Attached Figure Description

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0017] like Figure 1 , Figure 2 As shown, the retaining ring installation device provided in this embodiment includes a support 1, a slide rod 4, a base 5, and a pressure rod 6.

[0018] The support 1 includes a base plate 11, a vertical plate 12 connected to the base plate 11, and a platform 13 connected to the vertical plate 12, with the platform 13 located above the base plate 11.

[0019] The slide bar 4 includes a first shaft portion 41, a second shaft portion 42, and a third shaft portion 43 arranged sequentially. The diameter of the second shaft portion 42 is larger than the diameter of the first shaft portion 41. The diameter of the third shaft portion 43 is smaller than the diameter of the second shaft portion 42.

[0020] The pressure rod 6 includes a handle 2 and a support rod 3 hinged to the handle 2. One end of the handle 2 is hinged to the upper end of the upright plate 12, and the other end of the handle 2 forms the force-bearing end. The end of the support rod 3 away from the handle 2 is hinged to the upper end of the first shaft portion 41. The first shaft portion 41 is slidably connected to the platform 13. The outer surface of the second shaft portion 42 forms a first mounting end.

[0021] The base 5 is mounted on the base plate 11. The base 5 has an inner hole 51 that is adapted to the third shaft portion 43. The upper end of the third shaft portion 43 forms a second mounting end. The inner hole 51 is a stepped hole, and the third shaft portion 43 is a stepped shaft.

[0022] In use, the press-in part 20 is first heated to a set temperature, increasing the size of the shaft hole 201. Then, the heated shaft hole 201 of the press-in part 20 is fitted onto the second mounting end of the third shaft portion 43, with a clearance fit of 0.05–0.2 mm. The retaining ring 10, after installing the O-ring rubber pad, is placed on the first mounting end. Pressure is applied to the force-bearing end of the handle 2, driving the slide bar 4 downwards via the support rod 3. The third shaft portion 43 extends into the inner hole 51, followed by the second shaft portion 42 extending into the shaft hole 201, pressing the retaining ring 10 into the shaft hole 201. After the press-in part 20 cools, the retaining ring 10 and shaft hole 201 are in an interference fit, compressing the O-ring rubber pad. The slide bar 4 is then removed, completing the assembly.
