Description

Technical Field

[0001] The invention relates to the field of brake pad surface oil pollution treatment, in particular to an oil immersion device for the iron palm surface of an automobile brake pad. Background Art

[0002] The metal collar of a car brake pad is arc-shaped. After being machined and formed, a friction pad is attached to the inside of the collar. The displacement of the collar presses the friction pad against the brake pad, thereby applying the brakes to the car. After machining, a large amount of industrial oil remains on the surface of the collar, forming an oil film. If this oil film is not cleaned, it will affect the adhesion of the friction pad. Therefore, the oil film on the surface of the collar needs to be removed before installing the friction pad.

[0003] The Chinese open document (CN114622215B) describes an oil-immersing device for the surface of an iron palm used in the production of automobile brake pads. In this document, the iron palm is clamped by a special-shaped rotating placement frame and immersed in the degreaser with the iron palm. The iron palm swinging component can also be used to allow the rotating placement frame to rotate with the iron palm in the degreaser, so that bubbles attached to the surface of the iron palm are separated and floated up, thereby preventing the bubbles from affecting the effect of removing oil stains on the surface of the iron palm. However, the method of simply clamping the iron palm by the rotating placement frame is not stable. If the bubbles attached to the surface of the iron palm immersed in the degreaser are to be quickly removed, the speed of the iron palm rotation in the degreaser must be increased. However, if the speed is too fast, the iron palm is likely to fall from the top of the rotating placement frame (because the iron palm will be affected by the resistance of the liquid when rotating in the degreaser, causing the iron palm to change position). If the rotation speed is slow, it is impossible to ensure that the bubbles attached to the surface of the iron palm are completely removed, and it is impossible to ensure that the surface of the iron palm is completely adhered to the degreaser, and the oil attached to the surface of the iron palm cannot be completely removed.

[0036] The telescopic component 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.

When the column 5 descends, the first spring 13 can be pressed to compress it. When the covering plate 3 opens and lifts the column 5, the reaction elastic force generated by the first spring 13 can also assist the column 5 to rise stably with the receiving plate 6.

[0037] The connecting member includes a connecting block 21 located at the hinged portion of the covering plate 3 and the cylinder 1, and the connecting block 21 is "H"-shaped. The connecting block 21 and the covering plate 3 are hingedly assembled, and the end of the connecting block 21 away from the covering plate 3 is hinged to the movable end of the telescopic member 4. The telescopic member 4 is an electric push rod or a cylinder push rod.

A second spring 23 in the shape of an arc is also fixedly provided between the docking plate 22 and the connecting block 21, and the elastic stiffness of the second spring 23 is greater than the elastic stiffness of the first spring 13. When the telescopic member 4 extends to push the covering plate 3, so that the covering plate 3 is covered on the top of the cylinder 1, the second spring 23 will not undergo elastic deformation, but can also directly compress the first spring 13. Only when the covering plate 3 is completely covered on the upper end surface of the cylinder 1, the connecting block 21 will be bent under the continuous extension of the telescopic member 4, and the second spring 23 will begin to be elastically compressed.

[0039] Example 2: Please refer to Figure 2 and Figure 5 The present embodiment is a further explanation of the first embodiment. The lifting component includes a screw-on column 7 rotatably assembled on the top of the column 5, and a bent rod 8 is fixedly provided on the upper end surface of the screw-on column 7. A limit frame strip 9 is fixedly provided on the bottom of the covering plate 3. A positioning column 10 slidably mounted inside the limit frame strip 9 is fixedly provided on the end of the bent rod 8 away from the screw-on column 7. There are two limit frame strips 9, and the top of the bent rod 8 is slidably mounted between the two limit frame strips 9. The positioning column 10 can only perform linear motion inside the limit frame strips 9. In addition, the column 5 can only move up and down or rotate. Therefore, when the covering plate 3 is opened or closed, the column 5 can be moved up and down inside the cylinder 1 through the bent rod 8.

[0040] Example 3: Please refer to Figure 6-Figure 8This embodiment is a further explanation of other embodiments. The trigger component includes a sliding rod 24 that slides through the docking plate 22, and a push rod 25 is fixedly provided at one end of the sliding rod 24 away from the center of the covering plate 3. A first rack 26 is fixedly provided at one end of the sliding rod 24 close to the sealing cylinder 32, and a second rack 31 is fixedly provided at one end of the piston rod 33 close to the connecting block 21. The first rack 26 and the second rack 31 are distributed up and down. A limiting sleeve 27 is fixedly mounted on the upper end of the covering plate 3, and the first rack 26 and the second rack 31 are both slidably assembled inside the limiting sleeve 27. The interior of the limiting sleeve 27 is rotatably assembled with a rotating gear. The shaft 28 is provided with a first gear 29 meshing with the first rack 26 and the second rack 31, and the outer surface of the shaft 28 is fixedly provided with two second gears 30 meshing with the second rack 31. The first gear 29 and the first rack 26 are located between the two second gears 30. When the first rack 26 moves toward the sealing cylinder 32, the rotation of the shaft 28 will cause the second rack 31 to move with the piston rod 33 and the piston block 34 toward the direction of the connecting block 21, thereby sucking the air inside the cylinder 1 into the inside of the sealing cylinder 32.

[0041] The outer diameter of the second gear 30 is greater than that of the first gear 29 . When the shaft 28 rotates, the movement stroke of the second rack 31 is much greater than that of the first rack 26 , thereby increasing the movement stroke of the piston block 34 inside the sealing cylinder 32 .

[0042] The connection between the slide rod 24 and the push rod 25 is curved, so that the connection block 21 can push the slide rod 24 through the push rod 25 .

[0043] Working principle: the motor 14 does not have a self-locking function, that is, when the motor 14 is not running, the output end of the motor 14 can be manually rotated. When the covering plate 3 is in the open state, the staff adds the degreasing agent into the interior of the cylinder 1, and then puts the iron palm that needs to be degreased into the interior of each arc bearing frame 15. During the placement process, the spherical sleeve 19 needs to be elastically pressed on the upper end face of the iron palm. After the iron palm is placed, the covering plate 3 is gradually covered on the upper end face of the cylinder 1 through the extension of the telescopic part 4. During the covering process, the covering plate 3 can press the column 5 downward through the sliding engagement of the limit frame strip 9 and the positioning column 10, so that the distance between the first arc column piece 11 and the second arc column piece 12 is reduced, that is, the receiving plate 6 is immersed in the interior of the degreasing agent with the arc bearing frame 15, so that the iron palm is fully soaked in the degreasing agent.

[0044] After the covering plate 3 and the cylinder 1 are completely closed, the continuous extension of the telescopic part 4 will compress the second spring 23, so that the connecting block 21 pushes the sliding rod 24 through the push rod 25. When the first rack 26 is displaced, the second gear 30 is engaged with the second rack 31, so that 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 1 into the inside of the sealing cylinder 32. At this time, the air pressure inside the cylinder 1 is lower than the external atmospheric pressure, and the bubbles attached to the surface immersed in the degreaser will begin to expand until they burst. That is, the bubbles attached to the surface of the iron palm can be completely eliminated by the effect of negative pressure suction, so as to prevent the bubbles from affecting the contact area between the degreaser and the iron palm.

[0045] Afterwards, the motor 14 drives the column 5 to carry the receiving plate 6 to rotate clockwise for a period of time and counterclockwise for a period of time. During the rotation of the receiving plate 6 with the arc bearing frame 15, the iron palm will be pressed against the outer surface of several arc bars 16 due to the influence of centrifugal force. In addition, when the iron palm follows the rotation, it will be subjected to the resistance exerted by the degreasing agent, causing the iron palm to deviate in the opposite direction of rotation inside the arc bearing frame 15, that is, the iron palm will slip along the arc bar 16. By switching between clockwise and counterclockwise rotation, the iron palm can move back and forth inside the arc bearing frame 15, so that all parts of the iron palm can effectively contact the degreasing agent, allowing the degreasing agent to fully react with the oil adhered to the surface of the iron palm and eliminate the oil.
