Description

Technical Field

[0001] The utility model relates to the technical field of oil seal installation, in particular to an oil seal press-fitting device. Background Art

[0002] Oil seal is a sealing element used in mechanical parts. It is mainly used to prevent liquids (such as lubricating oil, hydraulic oil, etc.) from leaking from one area to another. It can also prevent dust, impurities, etc. from invading the inside of the parts that need to be protected from the outside. It is widely used in various machines and equipment, especially those systems containing rotating shafts or reciprocating parts, such as automobile engines, gearboxes, hydraulic systems and pumps.

[0003] Oil seals are common sealing components in mechanical equipment. Their installation usually requires precise size control to ensure the sealing effect. The traditional manual installation method of oil seals is not only inefficient, but also difficult to ensure installation accuracy, especially when installing oil seals inside narrow or deep well-shaped pipes. Therefore, there is an urgent need in the market for a device that can efficiently and accurately compress and install oil seals. Utility Model Content

[0004] The utility model aims to provide an oil seal pressing device, aiming to solve the problem that the traditional manual oil seal installation method in the prior art is not only inefficient but also difficult to ensure installation accuracy, especially when installing the oil seal inside a narrow or deep well-shaped pipe.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an oil seal pressing device, comprising two symmetrically arranged connecting plates, a connecting rod is rotatably arranged between the two connecting plates, and the two connecting plates are hingedly connected by the connecting rod, each of the connecting plates is provided with a through groove, a first positioning column is slidably arranged inside each through groove, two rows of threaded holes are symmetrically arranged on the connecting plates, and are respectively located on both sides of the through groove, a mounting plate is arranged above the through groove, and the mounting plate is connected to the first positioning column, a bolt is arranged on the mounting plate, and the bolt passes through the mounting plate and is threadedly installed in the threaded hole, and a second positioning column is arranged at one end of one of the connecting plates.

[0006] Preferably, a limiting ring is disposed at the lower end of each of the first positioning column and the second positioning column.

[0007] Preferably, an anti-slip sleeve is provided at one end of each connecting plate away from the connecting rod.

[0008] Preferably, the three limiting rings are located at the same height.

[0009] Preferably, a limiting block is provided on one of the connecting plates.

[0010] The beneficial effects of the utility model are:

[0011] 1. When the utility model is in use, the two first positioning columns are conveniently installed and disassembled by providing bolts and threaded holes, thereby facilitating adjustment of the distance between the two first positioning columns, thereby adapting to oil seals of different specifications.

[0012] 2. When the utility model is in use, by controlling the two connecting plates to rotate, the position between the two first positioning columns and the second positioning columns changes, thereby pulling the oil seal to deform and reduce the volume of the oil seal, thereby facilitating the installation of the oil seal into the interior of the pipe.

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-3 As shown, a press-fitting device for an oil seal 8 comprises two symmetrically arranged connecting plates 1, a connecting rod 2 is rotatably arranged between the two connecting plates 1, and the two connecting plates 1 are hingedly connected by the connecting rod 2, a through slot 3 is opened on each connecting plate 1, a first positioning column 4 is slidably arranged inside each through slot 3, two rows of threaded holes 7 are symmetrically arranged on the connecting plate 1, and are respectively located on both sides of the through slot 3, a mounting plate 5 is arranged above the through slot 3, and the mounting plate 5 is connected to the first positioning column 4, a bolt 6 is arranged on the mounting plate 5, and the bolt 6 penetrates the mounting plate 5 and is threadedly installed in the threaded hole 7, and a second positioning column 10 is arranged at one end of one of the connecting plates 1.

[0019] In this embodiment, the bolts 6 and the threaded holes 7 are provided to facilitate the installation and disassembly of the two first positioning columns 4, thereby facilitating the adjustment of the distance between the two first positioning columns 4 to accommodate oil seals 8 of different specifications. When the built-in oil seal 8 of the pipe is installed, the oil seal 8 is sleeved between the two first positioning columns 4, and the oil seal 8 is located behind the first positioning columns 4 to support the oil seal 8. When the two connecting plates 1 are controlled to rotate, the position between the two first positioning columns 4 and the second positioning columns 10 changes, thereby pulling the oil seal 8 to deform and reduce the volume of the oil seal 8, thereby facilitating the installation of the oil seal 8 inside the pipe.

[0020] like Figure 2 As shown, the lower ends of the first positioning column 4 and the second positioning column 10 are both provided with limiting rings 9 .

[0021] In this embodiment, a limiting ring 9 is provided to prevent the oil seal 8 from falling off from the first positioning column 4 and the second positioning column 10 when the two connecting plates 1 are rotated.

[0022] like Figure 1 As shown, an anti-slip sleeve 11 is provided at one end of each connecting plate 1 away from the connecting rod 2 .

[0023] In this embodiment, the anti-slip cover 11 is provided to facilitate people's grip.

[0024] like Figure 1 As shown, a limit block 12 is provided on one of the connecting plates 1 .

[0025] In this embodiment, the rotation angle of the two connecting plates 1 is limited by providing a limit block 12 .

[0026] Working principle: By setting the bolts 6 and the threaded holes 7, it is convenient to install and disassemble the two first positioning columns 4, so as to facilitate the adjustment of the distance between the two first positioning columns 4, so as to adapt to oil seals 8 of different specifications. When installing the built-in oil seal 8 in the pipe fitting, the oil seal 8 is sleeved between the two first positioning columns 4, and the oil seal 8 is located behind the first positioning columns 4 to support the oil seal 8. When the two connecting plates 1 are controlled to rotate, the position between the two first positioning columns 4 and the second positioning columns 10 changes, thereby pulling the oil seal 8 to deform and reduce the volume of the oil seal 8, so as to facilitate the installation of the oil seal 8 into the pipe fitting.
