Description

Technical Field

[0001] This utility model relates to the field of fuel pump assembly technology, specifically to an O-ring assembly device. Background Technology

[0002] The fuel pump is one of the core components of a car's fuel system. Its main function is to draw fuel from the fuel tank and deliver it to the engine's fuel injectors at a certain pressure. In this process, the fuel pump not only needs to ensure a stable fuel supply to meet the engine's needs under different conditions, but it also needs to withstand high temperatures, high pressures, and corrosive liquids. Therefore, the pre-installation of the sealing steel ball of its core component, the pressure valve, is particularly important.

[0003] Because O-rings are made of relatively soft material, they are prone to slipping during traditional hand assembly, making the process inconvenient. For face seals, a certain amount of pressure is required to secure the O-ring in the groove; pressing by hand often fails to tighten it, easily causing the O-ring to detach and preventing a proper seal. Manual assembly of O-rings is inefficient and cannot guarantee installation quality. Utility Model Content

[0004] To solve the above problems, this utility model provides an O-ring assembly device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an O-ring assembly device, comprising a guide sleeve and a pressure head, wherein the size of the guide sleeve matches the size of the O-ring, and the guide sleeve is used to fit the O-ring; the pressure head cooperates with the guide sleeve, and the pressure head is used to press the O-ring fitted on the guide sleeve onto the workpiece; a press head is provided above the pressure head; the press head is used to connect to a press.

[0006] As a preferred technical solution of this utility model: the press head is connected to the press head through a press head pad block.

[0007] As a preferred technical solution of this utility model, the pressure head is made of PEEK material.

[0008] As a preferred technical solution of this utility model: the pressure head is provided with at least one set of ventilation grooves.

[0009] As a preferred technical solution of this utility model: the pressure head is provided with a set of ventilation grooves.

[0010] As a preferred technical solution of this utility model: the upper part of the guide sleeve is frustum-shaped.

[0011] This utility model has the following beneficial effects:

[0012] 1. When installing O-rings, workers simply need to place the O-ring onto the guide sleeve, which is easy to do. Using a press, the O-ring can be fixed in the groove with a certain pressure, resulting in good sealing effect and high installation quality.

[0013] 2. The guide sleeve is designed to be coaxial with the workpiece, automatically aligning when the guide sleeve is placed, saving manpower and resources.

[0014] 3. Press head: The press head is made of PEEK material, which ensures that the O-ring will not be deformed during the pressing process and will not be damaged. It has good waterproof, oil-proof, wear-resistant and corrosion-resistant properties.

[0015] 4. The design of the venting groove ensures that the air in the groove can be discharged during pressing. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-2As shown, this embodiment of the utility model provides an O-ring assembly device, including a guide sleeve 1 and a pressure head 2. The size of the guide sleeve 1 matches the size of the O-ring 3. The guide sleeve 1 is used to fit the O-ring 3. The guide sleeve 1 is coaxial with the workpiece 7 and automatically centers when the guide sleeve 1 is placed. The pressure head 2 cooperates with the guide sleeve 1 and is used to press the O-ring 3 fitted on the guide sleeve 1 onto the workpiece 7. A press head 4 is provided above the pressure head 2. The guide sleeve 1 is placed on the workpiece 7, the O-ring 3 is fitted on the guide sleeve 1, and the pressure head 2 is placed above the guide sleeve 1. After the equipment is started, the press automatically presses down through the press head 4. The press head 4 is configured so that the pressing force and displacement can be monitored to ensure controllable assembly process. The press head 4 presses the O-ring 3 downward along the guide sleeve 1 into place. During the pressing process, it moves downward along the cylindrical guide surface to ensure assembly direction and position. When installing the O-ring 3, the worker only needs to put the O-ring 3 on the guide sleeve 1, which is convenient for operation. By using the press to press down, a certain pressing force can be used to fix the O-ring 3 in the groove, resulting in good sealing effect and high installation quality.

[0024] To prevent the press head 4 from being damaged during use, the press head 4 is connected to the press head 2 via a press head pad 5. The press head 2 is preferably made of PEEK material, ensuring that it does not deform during the pressing process and does not damage the O-ring seal 3. It also has good waterproof, oil-proof, wear-resistant, and corrosion-resistant properties. To prevent air from being trapped inside the groove after the O-ring seal 3 is pressed in, the press head is provided with at least one set of venting grooves 6; in this embodiment, one set of venting grooves 6 is preferred. The upper part of the guide sleeve 1 is frustum-shaped, facilitating the installation of the O-ring seal 3 onto the guide sleeve 1.
