[0005] The utility model aims to provide an engine cylinder flip clamping device to solve the problem that the clamping mechanism of the existing engine cylinder is fixed during the detection and processing process, so it is inconvenient to inspect and repair different positions of the engine.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An engine cylinder flipping clamping device comprises a lifting base, a clamping platform and a flipping frame which are arranged in sequence from bottom to top. The flipping frame is slidably arranged on both sides of the top surface of the clamping platform through a sliding connection structure, and a rotating clamping mechanism is provided on the upper part of the flipping frame.

[0008] By rotating the clamping mechanism, not only can the engine cylinder be clamped, but also the longitudinal rotation of the cylinder can be achieved, which makes it easy to inspect and repair different positions of the engine.

[0009] As a further preferred embodiment of the utility model, the lifting platform includes a base and a lifting frame, the lifting frame is arranged on the top of the base, one end of the lifting frame is rotatably connected to the base through a rotating shaft frame, the bottom end of the lifting frame is connected to a guide rail slider, and one side of the guide rail slider is connected to a thrust cylinder, and the other side of the guide rail slider is connected to a lifting cylinder.

[0010] Through the cooperation of the thrust cylinder and the lifting cylinder, the lifting frame can be flipped, which makes it easy to flip the cylinder clamped on the rotating clamping mechanism 90 degrees horizontally, making it easier to inspect and repair different positions of the engine.

[0011] As a further preferred embodiment of the present invention, the guide rail sliders are slidably matched with both sides of the bottom surface of the lifting frame, and the guide rail sliders are movably connected to the thrust cylinder and the lifting cylinder respectively.

The bottom surface of the flip frame is connected to the frame seat. The clamping cylinder is also arranged in the slide groove. The clamping cylinder is located on the outside of the frame seat. The cylinder rod of the clamping cylinder is connected to the frame seat.

[0014] Under the push of the clamping cylinder, the frame seat can move in the slide groove, and the flip frame can also move with the frame seat. Pushing the flip frame inward can clamp the cylinder, and pushing the flip frame outward can release the cylinder.
