[0035] When the lifting bending arm 6 needs to be adjusted to move close to the front and back of the engine cylinder body in this embodiment, the orientation angle of the lifting bending arm 6 can be adjusted by the movable rotating shaft 531, so that the lifting bending arm 6 is rotated to face the lateral position of the engine cylinder body, and then the hydraulic jack 61 and the anti-skid suction cup 62 are locked at the bottom of the engine cylinder body again, so that the front and back of the engine cylinder body are exposed, and the front and back of the engine cylinder body are polished and processed by the operator.

[0036] The top frame 2 is provided with an engine cylinder lifting anti-shaking unit at the bottom area.

[0037] The engine cylinder lifting anti-shaking unit comprises vertical guide rails 42, the surface of the vertical frame 4 is provided with vertical grooves 41, the vertical guide rails 42 are installed inside the vertical grooves 41, the vertical guide rails 42 are arranged in several groups, the moving pressing plate 43 is installed at the moving end of the vertical guide rail 42, the positioning plug rod 44 is installed at the bottom of the moving pressing plate 43, the positioning plug hole 54 is arranged at the surface edge area of the lifting platform 5, and the positioning plug rod 44 is movably inserted into the inside of the positioning plug hole 54.

[0038] In this embodiment, by driving the vertical guide rail 42 to descend, the moving end of the vertical guide rail 42 drives the moving pressing plate 43, and the moving pressing plate 43 drives the positioning plug rod 44 to descend and insert into the positioning plug hole 54 area on the surface of the lifting platform 5, and follows the movement in the lifting process of the lifting platform 5, so as to ensure the multi-point positioning of the lifting platform 5, reduce the shaking of the lifting platform 5 area, and ensure the locking lifting effect of the engine cylinder.

[0039] Working principle: in the process of using the device, the operator first places the engine cylinder to be processed on the surface of the heightening frame 11 at the top of the cylinder frame 1. Due to the arrangement of the heightening frame 11, the surface of the engine cylinder can maintain a lifting height from the ground. Then the operator can drive the two groups of winding rollers 31 to rotate and release. The rotation of the winding roller 31 will continuously release the winding chain 32 wound on the surface of the winding roller 31. After the winding chain 32 is released, the lifting platform 5 connected at the bottom of the winding chain 32 will be lowered and released. The lifting bending arm 6 at the bottom of the lifting platform 5 will move close to the bottom area of the engine cylinder. Then the movable rotating shaft 531 is driven to rotate the lifting bending arm 6. After the lifting bending arm 6 rotates, the anti-skid suction cup 62 arranged in the area of the lifting bending arm 6 will rotate to the edge area of the bottom of the engine cylinder. Then the hydraulic jack 61 at the bottom of the anti-skid suction cup 62 is driven, so that the anti-skid suction cup 62 is tightly pressed on the bottom of the engine cylinder, thereby completing the locking of the bottom of the engine cylinder. Then the operator drives the winding roller 31 to reset and wind the winding chain 32, so as to lift the engine cylinder by the lifting platform 5 and the lifting bending arm 6, and facilitate the surface suspension processing of the engine cylinder.

[0040] When the operator area processes the two side areas of the engine cylinder body, the operator can loosen the two groups of hydraulic jacks 61 and anti-skid suction cups 62 clamped on the side of the engine cylinder body, and then the engine cylinder body is suspended and stabilized by the remaining two groups of hydraulic jacks 61 and anti-skid suction cups 62 clamped on the front and back of the engine cylinder body. Then drive the moving guide rail 55 at the top of the lifting bending arm 6 that needs to be adjusted in position. When the moving guide rail 55 moves, it will drive the sliding sleeve block 53 to slide on the surface of the sliding square tube 52. When the sliding sleeve block 53 slides, it can drive the movable shaft 531 at the bottom and the lifting bending arm 6 to adjust the position. When the lifting bending arm 6 that needs to be adjusted is moved close to the front and back of the engine cylinder body, the orientation angle of the lifting bending arm 6 can be adjusted through the movable shaft 531, so that the lifting bending arm 6 rotates towards the front and back of the engine cylinder body. Then lock the bottom of the engine cylinder body by driving the hydraulic jacks 61 and anti-skid suction cups 62 again, so that there is no clamping obstruction on the side of the engine cylinder body, which facilitates the effective processing of the side of the engine cylinder body by the operator.

[0041] When the operator area processes the front and back areas of the engine cylinder body, the operator can loosen the two groups of hydraulic jacks 61 and anti-skid suction cups 62 clamped on the front and back of the engine cylinder body. Then the engine cylinder body is suspended and stabilized by the remaining two groups of hydraulic jacks 61 and anti-skid suction cups 62 clamped on the lateral area of the engine cylinder body. Then drive the moving guide rail 55 at the top of the lifting bending arm 6 originally located in the front and back areas of the engine cylinder body to move. When the moving guide rail 55 moves, it will drive the sliding sleeve block 53 to slide on the surface of the sliding square tube 52. When the sliding sleeve block 53 slides, it can drive the movable shaft 531 at the bottom and the lifting bending arm 6 to adjust the position. When the lifting bending arm 6 that needs to be adjusted is moved close to the front and back of the engine cylinder body, the orientation angle of the lifting bending arm 6 can be adjusted through the movable shaft 531, so that the lifting bending arm 6 rotates towards the lateral position of the engine cylinder body. Then lock the bottom of the engine cylinder body by driving the hydraulic jacks 61 and anti-skid suction cups 62 again, so that the front and back of the engine cylinder body are exposed, which facilitates the polishing and polishing processing of the front and back of the engine cylinder body by the operator.

[0042] After the display and adjustment of the front, back and lateral machining areas of the engine cylinder block, and while the engine cylinder block is lifted by the lifting platform 5 through the winding and unwinding control of the hoisting chain 32, in order to reduce the excessive shaking of the hoisting bending arm 6 at the bottom of the lifting platform 5 and the engine cylinder block during the lifting process, and to avoid the problem of the engine cylinder block falling off the hoisting bending arm 6, the lowering of the vertical guide rail 42 can be driven, the moving pressing plate 43 at the moving end of the vertical guide rail 42 is driven to move, the positioning inserting rod 44 is driven by the moving pressing plate 43 to lower and insert into the positioning inserting hole 54 area on the surface of the lifting platform 5, and to follow the movement during the lifting process of the lifting platform 5, so as to ensure the multi-point limiting of the lifting platform 5, reduce the shaking of the lifting platform 5 area, and ensure the locking and lifting effect of the engine cylinder block.
