Description

Technical Field

[0001] This utility model belongs to the field of precision coating technology, and specifically relates to an auxiliary device for accurately positioning and applying adhesive / oil to a sealing ring in an installation groove. More specifically, it is a sealing ring positioning and oiling mechanism. Background Technology

[0002] In industrial production, especially in precision instruments, automotive parts, electronic equipment, and medical devices, applying adhesive or oil to sealing rings is a crucial process for ensuring product sealing performance. Currently, most adhesive and oil application mechanisms on the market use a top-down direct coating method, lacking effective sealing ring positioning devices. Because sealing rings are inherently elastic and relatively small, especially those with an inner diameter of 5mm or less, they are prone to displacement or deformation within the mounting groove, leading to inaccurate adhesive application and uneven adhesive coverage. Utility Model Content

[0003] In view of the above-mentioned defects in the existing technology, the present invention aims to solve the problem that "the sealing ring is prone to displacement or deformation in the installation groove due to the lack of effective positioning during the sealing ring oiling process, resulting in inaccurate oiling position and uneven oil coverage".

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A sealing ring positioning and oiling mechanism, comprising, Oiling components are used to supply coating media (grease, adhesive, etc.) to the sealing rings; Also includes: A limiting component is configured to move in coordination with the oiling component; the limiting component is configured to abut and press against the sealing ring before or simultaneously with the oiling component applying the sealing ring, thereby limiting the displacement of the sealing ring within its mounting groove.

[0005] This invention introduces an active limiting mechanism, which fundamentally ensures coating accuracy by fixing the sealing ring before or during oiling. Before or simultaneously with oiling, the oiling component abuts against and presses against the upper surface of the sealing ring, thereby limiting any displacement of the sealing ring within its mounting groove and creating a stable coating environment.

[0006] Furthermore, the limiting component includes a guide portion; the guide portion can be an inclined surface or a conical surface. The guide portion is configured to guide the sealing ring to tend to move axially when the limiting component abuts against the sealing ring. This pressure causes the sealing ring to fit more tightly against the bottom of the mounting groove, further enhancing the stability and reliability of the positioning.

[0007] Furthermore, the guide portion can guide and force the sealing ring to move downwards, making it more tightly embedded in the bottom of the mounting groove.

[0008] Furthermore, the oiling component is positioned with its outlet facing the limiting component, preferably with its outlet tilted upwards. This design allows the oil to be sprayed more precisely onto the sealing ring that has been pressed and fixed by the limiting component, ensuring the coating effect.

[0009] Furthermore, the central axis of the limiting component and the central axis of the oiling component are located in the same vertical plane.

[0010] Furthermore, the end of the limiting component and the end of the oiling component are spaced apart in the horizontal direction, so that when moving towards the sealing ring, the limiting component contacts and presses against the sealing ring before the oiling component. This non-flush end design spatially ensures the "positioning first, then gluing" action sequence, thereby more reliably realizing the limiting function.

[0011] Furthermore, the limiting component is located above the oiling component.

[0012] Furthermore, the limiting component is arranged in a horizontal direction.

[0013] Furthermore, an acute angle α is formed between the central axis of the limiting component and the central axis of the oiling component, with the angle α ranging from 5° to 45°. If the angle is too small (<5°), the liquid outlet direction is too horizontal, the oil spray trajectory may be poor, making it difficult to accurately control the coating point, and the downward guiding effect of the limiting component will be weakened; if the angle is too large (>45°), the liquid outlet direction is too vertical, and the liquid outlet end may interfere with the limiting component or the workpiece, making it impossible to guarantee the "limiting component contacts first" action sequence, thus defeating the original design purpose. The range of 5°-45° ensures, on the one hand, that the limiting component can effectively contact and press down on the sealing ring first, and on the other hand, that the oiling component has an ideal tilt angle, which can accurately apply the oil to the already compressed and fixed sealing ring, avoiding interference.

[0014] Furthermore, the oiling component is an oiling needle, the end of which is used to connect to an oiling device.

[0015] This utility model may also include an automated execution platform, which includes a base, a stand slidably mounted on the base, and a drive component. The oiling component and the limiting component are mounted on the stand, and the drive component provides power to drive the stand to slide as a whole, thereby realizing the automatic feeding and retraction of the mechanism and improving production efficiency and consistency.

[0016] Compared with the prior art, the present invention has the following significant advantages: 1. High coating precision and stable quality: Through the active pressing and positioning function of the limiting component, the problem of displacement of the sealing ring during the oiling process is completely solved, ensuring that the oil is 100% accurately and evenly coated on the designated position of the sealing ring, which greatly improves product consistency and sealing reliability. 2. High versatility, especially suitable for small sealing rings: This mechanism has been optimized for small-sized sealing rings that are difficult to handle, effectively solving the industry pain points of easy deformation and difficulty in fixing, and expanding the application range of the equipment; 3. High degree of automation and improved production efficiency: The entire mechanism can be integrated into an automation platform to achieve precise reciprocating motion, reduce manual intervention, lower the difficulty of operation, and significantly improve production efficiency and yield.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Reference Figure 1 and Figure 2A sealing ring positioning and oiling mechanism includes an automated execution platform, an oiling component 1, and a limiting component 2. The automated execution platform includes a base 6 and a stand 7 slidably mounted on the base 6. The base 6 is a rectangular plate, horizontally oriented, with a pair of linear guide rails 61 fixedly mounted on its top surface along its length. The stand 7 includes a base plate, a vertical plate, an L-shaped connecting arm, and a mounting block. The base plate is fixedly connected to a slider of the linear guide rails 61; the vertical plate is vertically fixed to the top surface of the base plate; a triangular rib is fixed between the vertical plate and the base plate; one end of the L-shaped connecting arm is fixed to the vertical plate, and the other end is connected to the mounting block. Both the oiling component 1 and the limiting component 2 are mounted on the stand 7 via the mounting block.

[0021] Reference Figure 1 and Figure 2 The base 6 has a driving component 8 at one end and a hydraulic buffer 9 at the other end, located on opposite sides of the upright 7. In this embodiment, the driving component 8 is a hydraulic cylinder, with its movable end connected to the upright 7. The driving component 8 provides pushing and pulling power to drive the upright 7 to slide along the linear guide pair 61. In other embodiments, a pneumatic cylinder, an electric cylinder, or a servo motor can also be used as the driving component 8. The hydraulic buffer 9 is installed at the end of the linear guide pair 61 to prevent the upright 7 from experiencing a hard collision at the end of its stroke.

[0022] Reference Figure 2 and Figure 3 The oiling component 1 is used to supply a coating medium (such as grease or adhesive) to the sealing ring 3. In this embodiment, the oiling component 1 includes an oiling needle 11 mounted on the stand 7 via a mounting block, and its end is connected to a spray valve 12. The spray valve 12 is provided with an inlet pipe connector 121 for connecting to an external oiling device (not shown in the figure), such as an oil pump, via a pipeline.

[0023] Reference Figure 2 and Figure 3 The limiting component 2 is also fixedly mounted on the stand 7 via a mounting block, allowing the limiting component 2 and the oiling component 1 to move collaboratively. The limiting component 2 is configured to abut and press against the upper end face of the sealing ring 3 before the oiling component 1 applies the oil, thereby limiting the displacement of the sealing ring 3 within its product mounting groove 41. In this embodiment, the limiting component 2 is rod-shaped, comprising a head section, a middle section, and a tail section. The tail section is used to connect with the mounting block; the middle section is a circular rod with a gradually decreasing diameter, positioned horizontally; the head section is hemispherical, forming a guide portion 21 with a spherical arc surface, and there is a smooth transition between the head section and the middle section. In other embodiments, the guide portion 21 may also be of other shapes, such as a pyramid shape with an inclined guide surface.

[0024] Reference Figure 2 and Figure 3In this embodiment, the liquid outlet of the oiling needle 11 is inclined upwards, and its liquid outlet direction is towards the limiting component 2. The central axis of the limiting component 2 and the central axis of the oiling needle 11 are located in the same vertical plane, and the limiting component 2 is located above the oiling needle 11.

[0025] Reference Figure 2 and Figure 3 To ensure that the limiting component 2 performs its positioning function before the oiling component 1, the end of the limiting component 2 and the end of the oiling component 11 are spaced apart by a distance D in the horizontal direction. This design spatially ensures a reliable timing sequence of "positioning first, then oiling". An acute angle α is formed between the central axis of the limiting component 2 and the central axis of the oiling needle 11. After repeated verification, the optimal range of angle α is between 5° and 45°. For example, in this embodiment, the angle α is 30°. This angle ensures the limiting component takes priority while obtaining the optimal oiling trajectory and avoiding interference between components.

[0026] Working principle: Reference Figure 2 , Figure 3 and Figure 4 During operation, the drive component 8 pushes the stand 7 towards the workpiece 4. First, the guide part 21 of the limiting component 2 contacts and presses against the sealing ring 3. The spherical arc surface of the guide part 21 guides and forces the sealing ring 3 to move downwards, making it more tightly embedded in the bottom of the mounting groove 41 and stabilizing it within the mounting groove 41. Subsequently, the oiling needle 11 reaches the working position and precisely applies oil to the fixed sealing ring 3. After completion, the drive component 8 pulls the mechanism back, completing one work cycle.
