[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] The following is combined Figures 1 to 5 The embodiments of this utility model are described below.

[0031] This utility model embodiment provides a ball pin oiling mechanism, including:

[0032] The base plate 100 has upwardly extending support plates 101 on its left and right sides, and an upwardly extending guide rod 102 in the middle of the base plate 100.

[0033] Ball pin support assembly 200, which is movably mounted on the guide rod 102, is used to support ball pin 700;

[0034] The guide assembly includes a guide rail plate 301 and a slider 302. The two guide rail plates 301 are disposed on the front and rear sides of the support plate 101. The guide rail plate 301 is provided with a guide groove 3011, which passes through the guide rail plate 301 along the front-rear direction of the base plate 100 and extends along the left-right direction of the base plate 100. The slider 302 is movably disposed between the two guide rail plates 301. The slider 302 is connected to the ball pin bearing assembly 200 through a linkage mechanism.

[0035] The coating mechanism includes an oiling sponge 401 and a smoothing sponge 402. The oiling sponge 401 is disposed on one side of the slider 302, and the smoothing sponge 402 is disposed on the other side of the slider 302. The oiling sponge 401 and the smoothing sponge 402 are respectively disposed on opposite sides of the two sliders 302. When the ball pin bearing assembly 200 carries the ball pin 700 and moves downward under pressure, the two sliders 302 move towards each other along the guide groove 3011. The oiling sponge 401 and the smoothing sponge 402 are respectively driven by the sliders 302 to the oiling surface 701 of the ball pin 700. The surface of the oiling sponge 401 is wetted with lubricating oil. The oiling sponge 401 is used to coat the ball pin 700 carried by the ball pin bearing assembly 200 with lubricating oil, and the smoothing sponge 402 is used to evenly smooth the lubricating oil coated on the ball pin 700.

[0036] The operation process of the ball pin oiling mechanism in this embodiment is as follows: The operator needs to apply an appropriate amount of lubricating oil to the surface of the oiling sponge 401 using a dropper or similar tool, according to the oiling requirements, to fully wet the sponge 401; the ball pin 700 is placed on the ball pin bearing assembly 200, and the ball pin 700 is pressed down; under pressure, the ball pin bearing assembly 200 moves downward along the guide rod 102, and through the linkage mechanism, drives the two side sliders 302 to slide towards each other along the guide groove 3011 of the guide rail plate 301; as... As the slider 302 moves, the oiling sponge 401 and the smoothing sponge 402 are moved to the oiling surface 701 of the ball pin 700. At this time, the lubricating oil wetted on the surface of the oiling sponge 401 begins to be applied to the oiling surface 701 of the ball pin. The operator holds the ball pin 700 and rotates it once on the ball pin bearing assembly to make the lubricating oil evenly cover the entire oiling surface 701. At the same time, the smoothing sponge 402 further smooths the applied lubricating oil to ensure that the lubricating oil is evenly distributed and to avoid oil accumulation or uneven application.

[0037] Compared to traditional manual oiling methods, the ball pin oiling mechanism in this embodiment replaces manual multi-tool operation with a simple mechanical linkage structure, simplifying the oiling process and improving oiling efficiency. Through the cooperative design of the oiling sponge 401 and the smoothing sponge 402, the lubricant is ensured to be applied evenly, avoiding the problem of uneven thickness caused by manual application, improving the oiling quality, and ensuring the lubrication effect of the ball pin.

[0038] In this embodiment, the oiling sponge 401 and the smoothing sponge 402 are fixed to the opposite sides of the two sliders 302 by adhesive bonding. In other embodiments, screw fastening can be used, with the screw passing through the sponge and threaded into the pre-drilled threaded hole on the side of the slider 302; alternatively, a snap-fit ​​structure can be used, with a slot provided on the side of the slider 302 to hold the sponge in the slot.

[0039] Furthermore, the oiling sponge 401 is an oleophilic and hydrophobic sponge, and the smoothing sponge 402 is a hydrophilic and oleophobic sponge.

[0040] This embodiment combines two sponges with different properties. The oiling sponge 401 is an oleophilic and hydrophobic sponge that can quickly absorb lubricating oil and retain it strongly due to its own properties, effectively reducing the dripping and waste of lubricating oil during the coating process. Moreover, due to its strong affinity for lubricating oil, it can ensure that the oiled surface 701 receives sufficient and uniform lubrication coverage. On the other hand, the smoothing sponge 402 is a hydrophilic and oleophobic sponge that repels lubricating oil and will not take away the coated lubricating oil during the smoothing process.

[0041] Furthermore, the ball pin bearing assembly 200 includes a sliding seat 201 and a positioning seat 202. The sliding seat 201 has a limiting groove that matches the guide rod 102. The sliding seat 201 is movably sleeved on the guide rod 102 through the limiting groove. The positioning seat 202 is detachably mounted on the sliding seat 201. The positioning seat 202 has an upwardly open ball pin placement groove 2021 that matches the shape of the ball pin 700.

[0042] In this embodiment, the upper limit groove of the sliding seat 201 and the guide rod 102 cooperate to ensure the stability of the ball pin bearing assembly 200 in its up and down movement; the detachable positioning seat 202 design makes it easy to replace the appropriate positioning seat 202 according to different specifications of ball pins, which improves the versatility of the ball pin oiling mechanism; the ball pin placement groove 2021 on the positioning seat 202 matches the shape of the ball pin 700, which can provide precise positioning, prevent the ball pin 700 from shaking or shifting during the oiling process, and improve the oiling accuracy.

[0043] Further, the linkage mechanism includes a first link 501, a second link 502, a pin 503, a third link 504, a fourth link 505, a first guide rod 506, and a second guide rod 507. The first link 501 is fixedly connected to the sliding seat 201, and the first link 501 and the pin 503 are hinged through the second link 502. The first guide rod 506 is located on the side of the guide groove 3011 away from the sliding seat 201 and is fixed to the support plate 101. The second guide rod 507 slides along the guide groove 3011, and the slider 302 is fixed to the second guide rod 507. The third link 504 is located away from the sliding seat 201. One end of the movable seat 201 is hinged to the first guide rod 506. The end of the third connecting rod 504 adjacent to the sliding seat 201 is rotatably connected to the pin 503. The end of the fourth connecting rod 505 adjacent to the sliding seat 201 is hinged to the second guide rod 507. The end of the fourth connecting rod 505 away from the sliding seat 201 is hinged to the pin 503. When the ball pin bearing assembly 200 carries the ball pin 700 and moves downward under pressure, the sliding seat 201 drives the slider 302 to move toward the sliding seat 201 through the first connecting rod 501, the second connecting rod 502, the pin 503, the third connecting rod 504, and the fourth connecting rod 505.

[0044] In this embodiment, the linkage system consisting of the first link 501, the second link 502, the pin 503, the third link 504, the fourth link 505, the first guide rod 506, and the second guide rod 507 in the linkage mechanism can convert the linear motion of the sliding seat 201 into the opposing motion of the two sliders 302. This design enables the synchronous and precise movement of the oiling sponge 401 and the smoothing sponge 402, ensuring that both form uniform pressure on the oiling surface 701 and improving the quality of lubricant coating.

[0045] Furthermore, the guide assembly also includes a third guide rod 303, which slides along the guide groove 3011, and the slider 302 is fixedly connected to the second guide rod 507 and the third guide rod 303 respectively.

[0046] Compared to the slider 302 being connected to a single guide rod, in this embodiment the slider 302 is connected to two guide rods, which can prevent the slider 302 from accidentally rotating along a single guide rod during movement and improve the stability when the two sliders 302 move towards each other.

[0047] Furthermore, limiting nuts 304 are respectively fitted at both ends of the third guide rod 303, and the limiting nuts 304 are used to limit the displacement of the slider 302 in the front-back direction.

[0048] In this embodiment, limiting nuts 304 are provided at both ends of the third guide rod 303, which can prevent the two sliders 302 from shifting back and forth when they move in opposite directions, and ensure that the oiling sponge 401 and the smoothing sponge 402 contact the ball pin 700 in the optimal working position.

[0049] Furthermore, the guide assembly also includes an elastic reset mechanism for causing the slider 302 to tend to move away from the slide seat 201.

[0050] After the ball pin 700 is oiled and removed, the ball pin bearing assembly 200 is no longer pressed downward. At this time, the elastic reset mechanism in this embodiment moves the two sliders 302 away from the sliding seat 201 to achieve reset. At the same time, the sliders 302 drive the sliding seat 201 to move upward through the fourth link 505, the third link 504, the pin 503, the second link 502 and the first link 501 to achieve reset of the ball pin bearing assembly 200, preparing for the next ball pin oiling operation. There is no need to manually move the two sliders 302, which improves the operation efficiency.

[0051] Furthermore, the elastic reset mechanism is a spring 305, one end of which is connected to the first guide rod 506, and the other end of which is connected to the second guide rod 507.

[0052] In this embodiment, the elastic reset mechanism is a spring 305, which has advantages such as simple structure, low cost, and convenient maintenance. The two ends of the spring 305 are respectively connected to a fixed first guide rod 506 and a sliding second guide rod 507. When the slider 302 moves (moves towards the sliding seat 201), it generates elastic deformation and stores energy. After the downward pressure of the sliding seat 201 is released, the spring 305 releases energy to reset the slider 302 (moves away from the sliding seat 201).

[0053] Furthermore, the ball pin bearing assembly 200 also includes a first fixing pin, a first positioning hole is provided on the sliding seat 201, the first positioning hole penetrates the sliding seat 201 in the vertical direction, a first fixing hole is provided on the bottom surface of the positioning seat 202, and the first fixing pin passes through the first positioning hole and is threadedly connected to the first fixing hole.

[0054] This embodiment facilitates quick disassembly and replacement of the positioning seat 202 through the threaded connection of the first fixing pin, improving maintenance efficiency. At the same time, it ensures a firm connection between the positioning seat 202 and the sliding seat 201, guaranteeing the stability of the ball pin 700.

[0055] Furthermore, the ball pin oiling mechanism also includes a second fixing pin 601. The guide plate 301 has a second positioning hole, and the support plate 101 has second fixing holes on its front and rear sides respectively. The second fixing pin 601 passes through the second positioning hole and is threadedly connected to the second fixing hole.

[0056] In this embodiment, the guide plate 301 is firmly fixed to the support plate 101 by the second fixing nail 601, thereby ensuring the reliability of the movement of the slider 302 and improving the oiling quality of the ball pin.

[0057] The preferred embodiments of the present invention have been described in detail above, but the present disclosure is not limited to the embodiments described.
