Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, specifically relating to an O-ring oiling and feeding mechanism. Background Technology

[0002] O-rings are a very common sealing element. Due to their advantages such as simple structure, low cost and good sealing performance, they are widely used in various mechanical equipment, such as the pipe connection parts of automotive cooling water systems.

[0003] To ensure O-rings provide a good seal and extend their service life during actual use, applying oil to the O-rings before assembly is an essential step. Oiling effectively reduces friction during installation, preventing damage from excessive friction, and also enhances their sealing performance, preventing media leakage.

[0004] However, traditional O-ring lubrication and feeding methods have many drawbacks. Early on, many production scenarios used manual lubrication, with workers manually applying oil to the O-ring surface using brushes or other tools. This method was not only extremely inefficient and unsuitable for large-scale production, but the evenness of the lubrication also depended entirely on the worker's experience and skill level, easily leading to uneven application. Some companies attempted to assist lubrication with simple fixtures, such as placing the O-rings in a grease-filled container and then using a scraper to smooth the grease surface and allow the O-rings to absorb the grease. However, this method was not only cumbersome to operate manually, but the scraper also tended to carry grease to one side of the movement direction while smoothing the grease surface, resulting in grease waste and requiring frequent replenishment, increasing production costs and operational complexity.

[0005] With the development of automation technology, some automated oiling equipment has emerged. However, existing automated oiling equipment is often complex in structure and expensive, requiring significant investment and maintenance costs. While some equipment can perform the oiling function, it lacks efficient and precise design in the O-ring feeding process, failing to seamlessly integrate with subsequent assembly steps. This results in an inefficient production flow, hindering further improvements in production efficiency. Utility Model Content

[0019] like Figure 1 As shown, the O-ring oiling and feeding mechanism includes a frame 1, an O-ring gripper, and an oiling mechanism. The frame 1 is equipped with an O-ring feeding station 2, and an O-ring assembly station is located on one side of the frame 1.

[0020] The O-ring gripper includes an insertion rod 3 and an O-ring ejector tube 4. One end of the insertion rod 3 is located inside the O-ring ejector tube 4 and is coaxially designed with the O-ring ejector tube 4. The O-ring ejector tube 4 is driven to move up and down by an ejector drive mechanism. The insertion rod 3 is driven to move up and down by a lifting drive mechanism. The insertion rod 3 is driven to move back and forth between the O-ring loading station 2 and the O-ring assembly station by a longitudinal translation drive mechanism.

[0021] The oiling mechanism includes a left clamping plate 5 and a right clamping plate 6, located above the O-ring loading station 2. The inner sides of the left clamping plate 5 and the right clamping plate 6 are respectively provided with arc-shaped clamping grooves 7, and oil grooves 8 are provided inside the arc-shaped clamping grooves 7. Oil supply pipes are connected to the left clamping plate 5 and the right clamping plate 6, respectively, and these pipes are connected to the corresponding oil grooves 8. The left clamping plate 5 and the right clamping plate 6 are driven to separate or close by an opening and closing drive mechanism. The insertion rod 3 rises to a certain height, positioning the O-ring between the left clamping plate 5 and the right clamping plate 6. The left clamping plate 5 and the right clamping plate 6 close, placing the O-ring around its perimeter in the arc-shaped clamping grooves 7 and contacting the oil in the oil grooves 8, thus completing the oiling process. Then, the left clamping plate 5 and the right clamping plate 6 open, the insertion rod 3 rises, and moves to the O-ring assembly station under the drive of a longitudinal translation drive mechanism.

[0022] Furthermore, the frame 1 has two O-ring feeding stations 2, two sets of O-ring grippers, and two sets of oiling mechanisms. This dual-station design improves the efficiency of O-ring oiling, feeding, and assembly.

[0023] Furthermore, the opening and closing drive mechanism includes a pneumatic gripper 9, which is mounted on the frame 1. The two gripping fingers of the pneumatic gripper 9 are fixedly connected to the left clamping plate 5 and the right clamping plate 6, respectively, and the opening and closing of the left clamping plate 5 and the right clamping plate 6 are controlled by the pneumatic gripper 9.

[0024] Furthermore, the translation drive mechanism includes a translation drive cylinder 10, a longitudinal translation slide rail 11 on the frame 1, a longitudinal translation slide plate 12 on the longitudinal translation slide rail 11, the longitudinal translation drive cylinder 10 drives the longitudinal translation slide plate 12 to move on the longitudinal translation slide rail 11, a vertical slide rail 13 on the longitudinal translation slide plate 12, a vertical slide plate 14 on the vertical slide rail 13, a lifting drive mechanism lifting cylinder 15, the lifting cylinder 15 drives the vertical slide plate 14 to move on the vertical slide rail 13, a horizontal mounting plate 16 is fixedly connected to the vertical slide plate 14, and the insertion rod 3 is fixedly connected to the horizontal mounting plate 16.

[0025] Furthermore, the ejection drive mechanism includes an ejection cylinder 17 mounted on the horizontal mounting plate 16, with the output shaft of the ejection cylinder 17 fixedly connected to the O-ring ejection tube 4. At the O-ring assembly station, the insertion rod 3 descends, carrying the O-ring, and inserts it into the workpiece to be assembled (e.g., a quick connector). Then, the ejection cylinder 17 drives the O-ring ejection tube 4 to descend, ejecting the O-ring fitted on the insertion rod 3, completing the O-ring assembly. Finally, the O-ring ejection tube 4 rises, and the insertion rod 3 rises.

[0026] Furthermore, the frame 1 is equipped with a transverse sliding rail 18, and a transverse moving slide plate 19 is provided on the transverse sliding rail 18. The transverse moving slide plate 19 is driven by a switching cylinder 20 to move on the transverse sliding rail 18. The transverse moving slide plate 19 has two grooves 21 arranged sequentially along the direction of the transverse sliding rail 18. A through hole is provided in the middle of the groove 21. The O-ring feeding station 2 is located in the groove 21. A connecting plate 23 is provided on one side of the transverse sliding rail 18. The connecting plate 23 is fixedly connected to the frame 1. The connecting plate 23 has two connecting ports 24. A connecting port 25 is provided on the side of the groove 21 near the connecting plate 23. The connecting port 25 corresponds to the connecting port 24. When the connecting port 25 is connected to the corresponding connecting port 24, the O-ring passes through the connecting port 24 and the corresponding connecting port 25 and enters the O-ring feeding station 2. The groove 21 positions the O-ring. Then the transverse moving slide plate 19 moves, so that the O-ring feeding station 2 is transferred to the area below the corresponding oiling mechanism.

[0027] Furthermore, a sensor 26 is provided on one side of the O-ring loading station 2 to detect the O-rings on the O-ring loading station 2. After the sensor 26 detects that there are O-rings on the O-ring loading station 2, it sends a feedback signal. The O-ring gripper then performs subsequent actions such as insertion, oiling, lifting, lateral movement, and descent based on the feedback signal.

[0028] Furthermore, the connection port 24 is connected to a vibrating feeder. The vibrating feeder delivers the O-rings one by one to the connection port 24.
