It controls the extension and contraction of the cylinder to achieve the transmission of force and motion to support the car body, adjust the height of the car body, control the hardness of the suspension system, and perform other actions that require precise control. Before assembling the car cylinder, in order to improve its sealing performance and meet the precision requirements, its inner surface needs to be polished to remove burrs, scratches, etc.

The lower part of the collecting bucket 26 is fixedly connected to the collecting bucket 26, and the transmission rod 8 passes through the collecting bucket 26 and is rotatably connected to the collecting bucket 26. The collecting bucket 26 can collect the debris falling from the inside of the automobile cylinder generated during the grinding process to prevent the debris from falling everywhere.

[0053] Working principle: When in use, the automobile cylinder is placed vertically between the two clamping plates 7, so that the multiple grinding blocks 9 and the scraper 10 are located inside the automobile cylinder and in contact with the inner surface of the automobile cylinder, and then the two electric push rods 6 are started, and the two clamping plates 7 are driven to move relative to each other through the extension of the two electric push rods 6 to clamp the automobile cylinder, and then the first motor 18 is started, the first motor 18 drives the first gear 20 to rotate, the first gear 20 drives the second gear 21 to rotate, and the second gear 21 drives the transmission rod 8 to rotate, and the transmission rod 8 drives the multiple grinding blocks 9 and the scraper 10 to rotate, and the multiple grinding blocks 9 rotate to grind the inner surface of the automobile cylinder, and the scraper 10 moves along the inner surface of the automobile cylinder to scrape the debris generated by the grinding of the inner surface of the cylinder, and the multiple first air holes 13 are located in front of the rotation direction of the scraper 10, and at the same time, the air pump 25 is started, and the air pump 25 extracts the air inside the transmission rod 8 through the second air inlet pipe 42, so that a negative pressure environment is formed inside the transmission rod 8.

[0054] When the transmission rod 8 rotates, the first guide cylinder 33 is driven to rotate, and the lower end inclined surface of the first guide cylinder 33 rotates along the upper end inclined surface of the second guide cylinder 34, so that the first guide cylinder 33 moves upward, and under the action of the second elastic member 37, the first guide cylinder 33 is reset, driving the first guide cylinder 33 to continuously move up and down, and the first guide cylinder 33 drives the piston 30 to move horizontally in the first connecting pipe 23 through the pull rope 44. When the piston 30 moves toward the direction of the transmission rod 8, air flows into the jet chamber through the first one-way valve 40. When the piston 30 moves to the first connecting pipe 23, the air flows into the jet chamber through the first one-way valve 40. When moving in the direction of the scraper 10, the air in the jet chamber flows into the first channel 15 through the second one-way valve 43 and is ejected through the multiple first air holes 13, and the air flow is intermittently ejected through the multiple first air holes 13 in this reciprocating manner, which produces an oscillating effect on the debris, causing the debris to fluctuate near the inner surface of the automobile cylinder, so that most of the debris on the inner surface of the automobile cylinder is blown up and fluctuates first, and then the scraper 10 scrapes up the remaining debris attached to the inner surface of the automobile cylinder and mixes it with the fluctuating debris, thereby increasing the oscillating effect of the fluctuating debris.

[0055] At the same time, when a negative pressure environment is formed inside the transmission rod 8, the air inside the second channel 16 is extracted through the two second connecting pipes 24, so that the multiple second air holes 14 generate suction, sucking up and down floating debris near the inner surface of the automobile cylinder, and allowing the debris to enter the collection box 38 through the transmission rod 8 and the second air intake pipe 42.
