[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 As shown,

[0017] A device for cleaning the inner wall of a hydraulic cylinder barrel, characterized in that it comprises a frame 2, a wastewater collection box 3 is fixedly connected to the frame 2, a placement frame 4 is provided on the wastewater collection box 3, clamping components are provided on both sides of the frame 2, a first push rod motor 5 is fixedly connected to the upper end of the frame 2, a support frame 6 is fixedly connected to the push rod of the first push rod motor 5, a turntable 7 is rotatably connected to the lower end of the support frame 6, two sliders 8 are symmetrically slidably provided at the lower end of the turntable 7, and a cleaning brush 9 is provided on the slider 8. A plurality of water outlet holes 10 are also provided on the slider 8. A second push rod motor 11 is fixedly connected to the upper end of the turntable 7. An extrusion block 12 is fixedly connected to the push rod of the second push rod motor 11. A first guide slope is provided on the extrusion block 12. The first guide slope abuts against the slider 8. A water tank 13 is also provided on the turntable 7. A water pipe 14 is provided at the lower end of the water tank 13. The water pipe 14 passes through the turntable 7 and is connected to the water outlet hole 10. A driving motor 15 for driving the turntable 7 to rotate is provided on the support frame 6.

[0018] In this embodiment, the cylinder to be cleaned is placed on the placement rack 4 and clamped by the clamping assembly. Then the first push rod motor 5 drives the support frame 6 to descend, so that the slider 8 extends into the cylinder. According to the size of the cylinder, the second push rod motor 11 drives the extrusion block 12 to descend, and the extrusion slider 8 moves to both sides until the bristles are against the inner wall of the cylinder. Then the water tank 13 sprays water through the water pipe 14 and sprays it onto the inner wall of the cylinder from the water outlet 10. At this time, the driving motor 15 drives the turntable 7 to rotate, so that the cleaning bristles 9 scrub the inner wall of the cylinder. The waste water generated by the scrubbing passes through the placement rack 4 and falls into the waste water collection tank 3. After the cylinder is cleaned, the water tank 13 sprays water through the water pipe 14 again to rinse the cleaning bristles 9 to ensure the cleaning power of the cleaning bristles 9.

[0019] In this embodiment, the clamping assembly includes two third push rod motors 16, which are fixedly connected to both sides of the frame 2, and arc-shaped clamping blocks 17 are fixedly connected to the push rods of the third push rod motors 16. After the cylinder to be cleaned is placed on the placement rack 4, the third push rod motor 16 drives the arc-shaped clamping blocks 17 to clamp both sides of the cylinder.
