Description

Technical Field

[0001] This utility model belongs to the field of tooling components technology, specifically relating to a disassembly device for a self-sealing valve of an oil receiving plug. Background Technology

[0002] The oil receiving plug consists of a contact assembly, a housing assembly, and a self-sealing valve assembly (including the valve, spring seat, spring, and washer). During disassembly of the oil receiving plug's self-sealing valve, the self-sealing valve spring must be compressed before the spring seat can be removed, and then disassembly can continue down to the individual components. Current disassembly methods involve using a set of separate retaining rings to press against the spring. While holding the retaining rings, one end of the oil receiving plug is placed on a cylindrical mounting base. The plug is then placed on a press platform, where the press compresses the spring against the retaining rings, allowing the self-sealing valve spring seat to be removed for disassembly (see...). Figure 1 This disassembly method is particularly dangerous. First, it can easily pinch hands during the pressing of the retaining ring and spring in the press, and the spring can also easily pop out and cause injury. Second, indentations often appear at the contact point between the cylindrical mounting base and the oil receiving plug, which can easily damage the oil receiving plug. The disassembly quality and efficiency are both very low. To improve the safety of oil receiving plug disassembly, as well as improve the quality and efficiency of disassembly, it is necessary to design a tool for installing and disassembling the self-sealing valve of the oil receiving plug to safely disassemble the self-sealing valve. Utility Model Content

[0003] The purpose of this utility model is to provide an installation and disassembly fixture for the safe disassembly of the self-sealing valve of the oil receiving plug, solving the problem of hand injury from spring clamps and injury from ejection during the disassembly process, while avoiding damage to the oil receiving plug by the fixture during the disassembly process, thus improving the quality and efficiency of disassembly.

[0004] This utility model provides a disassembly device for a self-sealing valve with an oil receiving plug, comprising an installation support, a disassembly clamping seat, and a press. The installation support is placed on the press table, and the oil receiving plug to be disassembled is installed on the installation support. The bottom of the disassembly clamping seat is located in the groove of the spring seat of the self-sealing valve to be disassembled, and the top of the disassembly clamping seat is placed under the press.

[0005] The mounting support includes an upper support, a lower support, an annular felt, and a support rod; the support rod is fixed on the lower support, and the upper support is fixed to the upper end of the support rod; the upper support is hollow in the middle, and an annular felt is fixed on the hollow surface, so that the oil receiving plug self-sealing valve does not directly contact the upper support when disassembled and under pressure, thus protecting the oil receiving plug from damage.

[0006] The disassembly clamping seat is a hollow cylindrical structure, integrally welded. The bottom of the disassembly clamping seat has four claw structures, which cooperate with the groove of the self-sealing valve spring seat to be disassembled, so as to achieve safe and convenient disassembly.

[0007] The shape of the mounting support is matched with the outer surface of the oil receiving plug housing. The hollow surface in the middle of the upper support is an inclined surface with an angle of 10 degrees, so that the oil receiving plug housing can fit completely with the mounting support, ensuring that the oil receiving plug is stable and the force is evenly distributed when it is installed in the mounting support.

[0008] Furthermore, the lower support base and the support rod, and the upper support base and the support rod are fixed together by nuts and washers.

[0009] Furthermore, the annular felt pad is glued to the upper support base.

[0010] Furthermore, the side of the disassembly clamping seat is provided with four annular windows.

[0011] The beneficial effects of this utility model are as follows: The disassembly method of the self-sealing valve of the oil receiving plug is optimized by adopting a felt-covered mounting support. The mounting support's shape, which matches the surface profile of the oil receiving plug housing, better protects the oil receiving plug from damage during disassembly. The disassembly clamping seat can directly engage with the self-sealing valve spring seat groove without manual assistance, pressing down on the gasket to compress the spring and achieve safe and convenient disassembly. This significantly reduces the risks of hand injuries or spring-induced injuries caused by manual disassembly. Therefore, this utility model solves the problem of damage to the oil receiving plug housing surface during disassembly of the self-sealing valve, eliminates the safety hazards of spring-induced injuries and hand pinches, saves costs, and improves the disassembly quality and efficiency of the self-sealing valve.

[0020] The disassembly device of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] The structure of the oil receiving plug to be disassembled according to this utility model includes a contact assembly, a housing assembly, and a self-sealing valve assembly (including a valve, a spring seat, a spring, and a washer).

[0022] like Figure 2 As shown, a disassembly device for a self-sealing valve with an oil receiving plug includes an installation support 1, a disassembly clamping seat 2, and a press 3; the installation support is placed on the press table, and the oil receiving plug to be disassembled is installed on the installation support; the bottom of the disassembly clamping seat is located in the groove of the spring seat of the self-sealing valve to be disassembled, and the top of the disassembly clamping seat is placed under the press.

[0023] like Figure 3 As shown, the mounting support 1 includes an upper support 11, a lower support 12, an annular felt 13, and a support rod 14. A support rod is fixed to the lower support, and the upper support is fixed to the upper end of the support rod. The upper support is hollow in the middle, and an annular felt is fixed to the hollow surface to prevent the oil receiving plug housing from directly contacting the upper support during disassembly and under pressure, thus protecting the oil receiving plug housing from damage. The hollow surface of the upper support is a 10-degree inclined plane that mates with the outer surface of the oil receiving plug housing.

[0024] like Figure 4 As shown, the disassembly clamping seat 2 is a hollow cylindrical structure, which is integrally welded. The bottom of the disassembly clamping seat has four claw structures. The claws cooperate with the groove of the self-sealing valve spring seat to be disassembled, so as to achieve safe and convenient disassembly.

[0025] The side of the disassembly clamping seat described in this utility model is provided with four annular windows, which make it easy to observe whether the spring is compressed to the point where the self-sealing valve spring seat can be disassembled, and also make it easy to remove the spring seat by hand.

[0026] like Figure 5As shown, place the mounting support 1 on the press machine 3 table, then install the oil receiving plug to be disassembled onto the mounting support 1, so that the housing of the oil receiving plug to be disassembled is snapped into the upper support 11 and fits against the annular felt 13. Install the disassembly clamping seat 2 onto the spring seat of the self-sealing valve, so that the four claws at the bottom of the disassembly clamping seat 2 are precisely engaged in the four slots of the self-sealing valve spring seat, contacting the washer of the self-sealing valve of the oil receiving plug. Then, by rotating the press machine downwards to contact the top of the disassembly clamping seat 2, slowly apply downward pressure by rotating the press machine handle. The disassembly clamping seat 2 presses the washer downwards, compressing the self-sealing valve spring. When it descends to the point where the self-sealing valve spring seat can be disassembled, stop pressing, remove the self-sealing valve spring seat, rotate the press machine handle back to the natural state, remove the disassembly clamping seat 2, remove the washer and self-sealing valve spring, and proceed with subsequent disassembly.
