Description

Technical Field

[0001] This utility model relates to the field of air compressor maintenance tooling technology, and in particular to a disassembly tooling for an air compressor oil-water separator. Background Technology

[0002] Air compressors, as a key piece of equipment specifically designed for compressing gases, share a similar construction principle with water pumps. Among the many types of air compressors, reciprocating piston, rotary vane, and rotary screw types dominate the market.

[0003] Taking the CR300AF EMU as an example, there are strict regulations for the maintenance of its main air compressor: when the operating mileage reaches 400,000 kilometers or the operating time reaches 360 days, the filter element of the oil-water separator must be replaced. In the traditional filter element replacement operation process, the staff usually use a belt wrench to disassemble the outer shell of the air compressor oil-water separator.

[0004] However, in practical applications, the installation interface of the oil-water separator adopts a concave-convex fit structure, which is inherently difficult to disassemble. Secondly, long-term operation causes the grease that seeps into the interface to solidify, significantly increasing the torque required for disassembly. More importantly, due to the limited contact area, ordinary belt wrenches are prone to slippage when applying excessive torque, ultimately preventing the oil-water filter from being disassembled properly, which seriously affects the disassembly efficiency and quality of the air compressor oil-water separator. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing method of using a belt wrench to disassemble the outer shell of an air compressor oil-water separator is not only laborious but also prone to slippage, thus reducing maintenance efficiency. Therefore, this utility model proposes a disassembly tool for an air compressor oil-water separator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A disassembly fixture for an air compressor oil-water separator includes a first clamping arm and a first clamping ring fixedly connected to the first clamping arm. The first clamping ring has a first serrated groove on its inner arc surface and a hinge at one end away from the first clamping arm. A second clamping ring is rotatably connected to the first clamping ring via the hinge. The second clamping ring has a second serrated groove on its inner arc surface. The second clamping ring has a second clamping arm fixedly connected to one end away from the hinge. When the second clamping arm moves in the opposite direction to the first clamping arm, the first clamping ring and the second clamping ring tend to unfold relative to each other.

[0007] In order to adjust the opening and closing of the first clamping ring and the second clamping ring, preferably, the hinge includes a fixed frame fixedly connected to the first clamping ring, a pin is rotatably connected to the fixed frame, and a limiting frame fixedly sleeved on the pin and fixedly connected to the second clamping ring.

[0008] To further guide and limit the positioning frame, the fixed frame is provided with an arc-shaped guide surface, and the side of the positioning frame closest to the fixed frame abuts against the arc-shaped guide surface.

[0009] For the purpose of protecting the housing, preferably, a first protective pad is fixedly bonded to the inner arc surface of the first clamping ring.

[0010] To further enhance the limiting effect while providing protection, the first protective pad is made of vulcanized rubber.

[0011] To protect the oil-water separator housing, preferably, a second protective pad is fixedly bonded to the inner arc surface of the second clamping ring.

[0012] To further enhance the anti-slip effect during protection, the second protective pad is made of vulcanized rubber.

[0013] Compared with the prior art, this utility model provides a disassembly fixture for an air compressor oil-water separator, which has the following advantages: 1. The disassembly fixture for the air compressor oil-water separator, through the setting of the hinge, can realize the opening and closing adjustment of the first clamping ring and the second clamping ring, which can be adapted to the housing of different sizes and improve the versatility of the fixture. 2. The disassembly fixture for the air compressor oil-water separator, through the first protective pad made of vulcanized rubber, can prevent damage to the housing when the first serrated groove bites into it, thereby improving its protective effect. 3. The disassembly fixture for the air compressor oil-water separator, through the second protective pad made of vulcanized rubber, can prevent damage to the housing when the second serrated groove bites into it, thus significantly improving the protective effect of the fixture.

[0014] All parts of the device not described herein are the same as or can be implemented using existing technology. This utility model uses the cooperation of the first clamping ring and the second clamping ring to cause the first and second serrated grooves to mesh on the oil-water separator housing, increasing friction, preventing slippage, and further improving the stability of disassembly. In addition, the use of the first clamping arm and the second clamping arm to form a lever system can reduce the required force intensity, thereby improving the disassembly efficiency of the housing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0019] Example: Reference Figures 1-4 A disassembly fixture for an air compressor oil-water separator includes a first clamping arm 1 made of metal, and a first clamping ring 2 fixedly connected to the first clamping arm 1. The first clamping ring 2 has a first serrated groove 3 on its inner arc surface, which allows it to engage with the oil-water separator housing. A hinge is provided at the end of the first clamping ring 2 away from the first clamping arm 1. A second clamping ring 5 is rotatably connected to the first clamping ring 2 via the hinge. The second clamping ring 5 has a second serrated groove 6 on its inner arc surface, which also allows it to engage with the oil-water separator housing. A second clamping arm 7 is fixedly connected at the end of the second clamping ring 5 away from the hinge. When the second clamping arm 7 moves in the opposite direction to the first clamping arm 1, the first clamping ring 2 and the second clamping ring 5 tend to open relative to each other. The maximum opening angle between the first clamping ring 2 and the second clamping ring 5 is 120 degrees, further improving the applicability of the disassembly fixture.

[0020] Specifically, by cooperating with the first clamping ring 2 and the second clamping ring 5, the first serrated groove 3 and the second serrated groove 6 are made to mesh on the oil-water separator housing, increasing friction, preventing slippage, and further improving the stability of disassembly. In addition, by using the first clamping arm 1 and the second clamping arm 7 to form a lever system, the required force intensity can be reduced, thereby improving the disassembly efficiency of the housing.

[0021] The hinge includes a fixed frame 4 fixedly connected to the first clamping ring 2, a pin 41 rotatably connected to the fixed frame 4, a limiting frame 42 fixedly sleeved on the pin 41 and fixedly connected to the second clamping ring 5, the fixed frame 4 has an arc-shaped guide surface, and the side of the limiting frame 42 close to the fixed frame 4 abuts against the arc-shaped guide surface to limit the limiting frame 42.

[0022] Specifically, the hinge mechanism enables the opening and closing adjustment of the first clamping ring 2 and the second clamping ring 5, which can be adapted to housings of different sizes and improve the versatility of the tooling.

[0023] A first protective pad 8 is fixedly bonded to the inner arc surface of the first clamping ring 2. The first protective pad 8 is made of vulcanized rubber.

[0024] Specifically, the first protective pad 8 made of vulcanized rubber can prevent damage to the shell when the first serrated groove 3 engages with the shell, thereby improving its protective effect.

[0025] A second protective pad 9 is fixedly bonded to the inner arc surface of the second clamping ring 5. The second protective pad 9 is made of vulcanized rubber.

[0026] Specifically, the second protective pad 9 made of vulcanized rubber can prevent damage to the housing when the second serrated groove 6 engages with the housing, thus significantly improving the protective effect of the tooling.

[0027] Working principle: When disassembling the oil-water separator housing of the air compressor, a reverse force is first applied to the free ends of the first clamping arm 1 and the second clamping arm 7 to cause relative displacement, thereby causing the first clamping ring 2 and the second clamping ring 5 to unfold. Then, the unfolded first clamping ring 2 and the second clamping ring 5 are fitted onto the outside of the housing, and the first clamping arm 1 and the second clamping arm 7 are moved in opposite directions to achieve the closing and locking of the first clamping ring 2 and the second clamping ring 5. During this process, the first serrated groove 3 and the second serrated groove 6 set on the inner arc surface of the first clamping ring 2 and the second clamping ring 5 form a tight engagement with the surface of the housing, ensuring the reliability and stability of the tooling positioning and effectively preventing relative sliding during the disassembly process.

[0028] To enhance the protective performance of the disassembly fixture, the inner surfaces of the first clamping ring 2 and the second clamping ring 5 are specially provided with a first protective pad 8 and a second protective pad 9 made of vulcanized rubber. This design ensures the clamping force while avoiding mechanical damage to the shell surface that may be caused by the serrated structure, thus significantly improving the protective effect of the fixture.

[0029] After the tooling is fixed, the operator applies pushing and pulling force to the first clamping arm 1 and the second clamping arm 7, using the clamping points on the housing as fulcrums to form an efficient lever transmission system. This mechanical design can significantly reduce the force required for operation, realize labor-saving operation, and thus significantly improve the work efficiency of disassembly.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
