Description

Technical Field

[0001] The present invention relates to the field of oil stain treatment on the surface of brake pads, and specifically to an oil liquid immersion device for the iron palm surface of automotive brake pads. Background Art

[0002] The iron palm of an automotive brake pad is arc-shaped. After being processed and formed, a friction gasket needs to be pasted on the inner side of the iron palm. The displacement of the iron palm presses the friction gasket onto the brake pad, thereby performing a braking operation on the vehicle. After the iron palm is processed, a large amount of industrial oil liquid remains on its surface, that is, there is an oil film on the surface. If this oil film is not completely removed, it will affect the pasting effect of the friction gasket. Therefore, before installing the friction gasket, the oil film on the surface of the iron palm needs to be removed.

[0003] A Chinese published document (CN114622215B) records an oil liquid immersion device for the iron palm surface in the production of automotive brake pads. In this document, the iron palm is clamped by a special-shaped rotating placement rack and immersed in a degreasing agent. The iron palm can also be rotated in the degreasing agent by the iron palm shaking component, which drives the rotating placement rack to rotate, so that the bubbles attached to the surface of the iron palm can be separated and float upward, avoiding the influence of bubbles on the effect of removing oil stains on the iron palm surface. However, the method of simply clamping and limiting the iron palm by the rotating placement rack is not stable. If the speed of the iron palm rotating in the degreasing agent is increased to ensure that the bubbles attached to the surface of the iron palm immersed in the degreasing agent can be quickly removed, the iron palm is likely to fall from above the rotating placement rack when the speed is too fast (because when the iron palm rotates in the degreasing agent, it will be affected by the resistance of the liquid and cause the position of the iron palm to change). If the rotation speed is slow, it cannot be ensured that the bubbles attached to the surface of the iron palm are completely removed, so it cannot be ensured that the surface of the iron palm can be completely adhered to by the degreasing agent, and the oil liquid adhered to the surface of the iron palm cannot be completely removed.

The driving unit is arranged at the bottom of the cylinder body 1.

[0020] The immersion unit includes a column 5 inside the cylinder body 1, and the column 5 is coaxially arranged with the cylinder body 1. At least one receiving plate 6 is fixedly sleeved on the outer surface of the column 5, and a plurality of arc-shaped bearing frames 15 distributed at equal circumferential intervals are fixedly embedded inside the receiving plate 6. Each arc-shaped bearing frame 15 is in a hollow shape. A plurality of arc-shaped strips 16 distributed at equal intervals are fixedly provided on the maximum arc surface inside each arc-shaped bearing frame 15. A plurality of rollers 17 distributed at equal intervals are rotatably assembled at the inner bottom of the arc-shaped bearing frame 15. The rollers 17 are used to carry the iron palm. The top of the arc-shaped bearing frame 15 is elastically rotatably assembled with a limit handle 18 through a torsion spring and a pin shaft. A spherical sleeve block 19 is rotatably assembled at the movable end of the limit handle 18. The limit handle 18 and the arc-shaped strip 16 are oppositely distributed. A lifting component is arranged between the top of the column 5 and the bottom of the sealing cover plate 3. When the sealing cover plate 3 swings, the column 5 can be moved up and down through the lifting component. The iron palm to be degreased is placed inside the arc-shaped bearing frame 15, and the spherical sleeve block 19 can be abutted against the upper end surface of the arc-shaped bearing frame 15 to prevent the iron palm from falling off the inside of the arc-shaped bearing frame 15.

[0021] The driving unit includes an extended cylinder column 2 fixedly and communicatively arranged at the bottom of the cylinder body 1, and the bottom of the extended cylinder column 2 is closed. A motor 14 is fixedly installed at the bottom of the extended cylinder column 2. The output end of the motor 14 is rotatably fitted inside the extended cylinder column 2. A telescopic member is arranged between the bottom of the column 5 and the output end of the motor 14. The output end of the motor 14 drives the column 5 to rotate through the telescopic member. A detachable sealing plug is arranged on the outer surface of the bottom of the extended cylinder column 2. Through the sealing plug, the liquid inside the cylinder body 1 and the extended cylinder column 2 can be discharged. Among them, the telescopic member can be telescopically adjusted inside the extended cylinder column 2 and the cylinder body 1 according to the position change of the column 5.

[0022] The telescopic member includes a second arc-shaped column piece 12 fixed to the output end of the motor 14, and a first arc-shaped column piece 11 fixed to the bottom of the column 5. The first arc-shaped column piece 11 and the second arc-shaped column piece 12 are arranged coaxially. The number of the first arc-shaped column pieces 11 and the second arc-shaped column pieces 12 is two each, and the two first arc-shaped column pieces 11 and the two second arc-shaped column pieces 12 are arranged in an interleaved butt joint. A first spring 13 is also placed inside the first arc-shaped column piece 11 and the second arc-shaped column piece 12, and both ends of the first spring 13 are fixed between the bottom of the column 5 and the output end of the motor 14. When the column 5 descends, the first spring 13 can be pressed and compressed. When the sealing cover plate 3 is opened and drives the column 5 to rise, the reaction elastic force generated by the first spring 13 can also assist the column 5 to drive the receiving tray 6 to rise stably.

[0023] The connecting member includes a connecting block 21 located at the hinged part of the sealing cover plate 3 and the cylinder body 1. The connecting block 21 is in an "H" shape. The connecting block 21 is hingedly assembled with the sealing cover plate 3, and one end of the connecting block 21 away from the sealing cover plate 3 is hinged to the movable end of the telescopic member 4. The telescopic member 4 is an electric push rod or a pneumatic cylinder push rod. A docking plate 22 is fixedly arranged on the upper end surface of the sealing cover plate 3, and the docking plate 22 is located on the side close to the connecting block 21. An arc-shaped second spring 23 is also fixedly arranged between the docking plate 22 and the connecting block 21, and the elastic stiffness of the second spring 23 is greater than that of the first spring 13. When the telescopic member 4 extends to push the sealing cover plate 3 and makes the sealing cover plate 3 cover the upper part of the cylinder body 1, the second spring 23 will not undergo elastic deformation, and it can directly compress the first spring 13. Only when the sealing cover plate 3 completely covers the upper end surface of the cylinder body 1, under the continuous extension of the telescopic member 4, the connecting block 21 will be bent, and at this time the second spring 23 begins to be elastically compressed.

[0024] The defoaming unit includes a sealing cylinder 32 fixed to the upper end face of the sealing cover plate 3. A piston block 34 is slidably assembled inside the sealing cylinder 32. One end of the piston block 34 close to the connecting block 21 is fixedly provided with a piston rod 33 that slidably penetrates through the sealing cylinder 32. A gas pipe 35 is fixedly connected and communicated between the end of the sealing cylinder 32 far from the connecting block 21 and the bottom of the sealing cover plate 3. Several air holes are provided at the end of the sealing cylinder 32 close to the connecting block 21. A triggering component is also provided between the connecting block 21 and the piston rod 33. When the sealing cover plate 3 and the cylinder body 1 are closed, the continuous upward flipping of the connecting block 21 will push the triggering component, causing the piston block 34 to move towards the connecting block 21, and the gas inside the cylinder body 1 can be sucked into the sealing cylinder 32, making the air pressure inside the cylinder body 1 less than the external air pressure. A return spring can also be assembled between the end of the piston block 34 close to the connecting block 21 and the sealing cylinder 32 to assist the later reset movement of the piston block 34. Embodiment 2: Please refer to Figure 2 and Figure 5 , this embodiment is a further description of Embodiment 1. The lifting component includes a rotary joint column 7 rotatably assembled at the top of the column 5. A curved rod 8 is fixedly provided on the upper end face of the rotary joint column 7. A limiting frame strip 9 is fixedly provided at the bottom of the sealing cover plate 3. A positioning column 10 is fixedly provided at the end of the curved rod 8 far from the rotary joint column 7 and is slidably fitted inside the limiting frame strip 9. The number of limiting frame strips 9 is two, and the top of the curved rod 8 is slidably fitted between the two limiting frame strips 9. The positioning column 10 can only move linearly inside the limiting frame strip 9. Coupled with the fact that the column 5 can only move up and down or rotate, when the sealing cover plate 3 is opened or closed, the column 5 can be moved up and down inside the cylinder body 1 by the curved rod 8. Embodiment 3: Please refer to Figures 6 - 8, This embodiment is a further illustration of other embodiments. The actuating component includes a slide bar 24 that slidably penetrates through the docking plate 22. One end of the slide bar 24 away from the center of the sealing cover plate 3 is fixedly provided with a push rod 25. One end of the slide bar 24 close to the sealing cylinder 32 is fixedly provided with a first rack 26. One end of the piston rod 33 close to the connecting block 21 is fixedly provided with a second rack 31. The first rack 26 and the second rack 31 are vertically distributed. A limiting sleeve frame 27 is fixedly erected on the upper end of the sealing cover plate 3. Both the first rack 26 and the second rack 31 are slidably assembled inside the limiting sleeve frame 27. A rotating shaft 28 is rotatably assembled inside the limiting sleeve frame 27, and the rotating shaft 28 is perpendicular to the first rack 26 and the second rack 31. A first gear 29 meshing with the first rack 26 is fixedly sleeved on the outer surface of the rotating shaft 28. Two second gears 30 meshing with the second rack 31 are also fixedly sleeved on the outer surface of the rotating shaft 28. The first gear 29 and the first rack 26 are between the two second gears 30. When the first rack 26 moves towards the sealing cylinder 32, the rotation of the rotating shaft 28 will cause the second rack 31 to drive the piston rod 33 and the piston block 34 to move towards the connecting block 21, thereby sucking the air inside the cylinder body 1 into the sealing cylinder 32.

[0025] The outer diameter of the second gear 30 is greater than that of the first gear 29. When the rotating shaft 28 rotates, the moving stroke of the second rack 31 is much greater than that of the first rack 26, thereby increasing the moving stroke of the piston block 34 inside the sealing cylinder 32.

[0026] The connection part between the slide bar 24 and the push rod 25 is curved, which facilitates the connecting block 21 to push the slide bar 24 through the push rod 25. Working principle: The electric motor 14 does not have a self-locking function, that is, when the electric motor 14 is not running, the output end of the electric motor 14 can be manually rotated. When the sealing cover plate 3 is in the open state, the staff adds the degreasing agent into the cylinder body 1, and then places the iron palm to be degreased into the interior of each arc-shaped bearing frame 15. During the placement process, the spherical sleeve block 19 needs to elastically press on the upper end surface of the iron palm. After the iron palm is placed, the telescopic member 4 extends to gradually cover the sealing cover plate 3 on the upper end surface of the cylinder body 1. During the covering process of the sealing cover plate 3, it can press the column 5 downward through the sliding fit of the limiting frame strip 9 and the positioning column 10, reducing the distance between the first arc-shaped column piece 11 and the second arc-shaped column piece 12, that is, making the receiving tray 6 with the arc-shaped bearing frame 15 immersed in the degreasing agent, allowing the iron palm to be fully soaked in the degreasing agent.

[0027] After the cover plate 3 and the cylinder body 1 are completely closed, the continuous extension of the telescopic member 4 will compress the second spring 23, causing the connecting block 21 to push the slide bar 24 through the push rod 25. After the first rack 26 is displaced, through the meshing of the second gear 30 and the second rack 31, the second rack 31 can pull the piston rod 33 and the piston block 34, so that the piston block 34 sucks the air inside the cylinder body 1 into the inside of the sealing cylinder 32. At this time, the air pressure inside the cylinder body 1 is less than the external atmospheric pressure, and the bubbles attached to the surface immersed in the degreasing agent will begin to expand until they burst, that is, through the action of negative pressure suction, the bubbles attached to the surface of the iron palm can be completely eliminated, avoiding the influence of bubbles on the contact area between the degreasing agent and the iron palm.

[0028] After that, the motor 14 drives the column 5 to drive the receiving tray 6 to rotate clockwise for a period of time and then counterclockwise for a period of time. During the rotation of the receiving tray 6 with the arc-shaped bearing frame 15, due to the influence of centrifugal force, the iron palm will be pressed against the outer surface of several arc-shaped strips 16. Moreover, when the iron palm rotates, it will be affected by the resistance exerted by the degreasing agent, causing the iron palm to shift in the opposite direction of the rotation direction inside the arc-shaped bearing frame 15, that is, the iron palm will slide along the arc-shaped strip 16. By switching between clockwise rotation and counterclockwise rotation, the iron palm can move back and forth inside the arc-shaped bearing frame 15, so that all parts of the iron palm can effectively contact the degreasing agent, enabling the degreasing agent to fully react with the oil adhered to the surface of the iron palm and eliminate the oil.

[0029] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
