[0025] The rotating structure includes a base 4, which is fixedly mounted on the outer surface of the flip hanger 1, and a limited slide bar 401 is slidably mounted inside the base 4, and a rack 402 for controlling the rotation of the engine cylinder head is fixedly mounted on the upper surface of the limited slide bar 401, and a gear 403 is meshed at the top of the rack 402, and the gear 403 is fixedly connected to the rotating rod 3 through a limiting structure installed inside to prevent the engine cylinder head from flipping over autonomously;

[0026] Specifically, the limit slide bar 401 is connected to the rack 402 to move, driving the gear 403 to connect the rotating rod 3 to control the engine cylinder head to flip, thereby saving manpower, ensuring that the engine cylinder head is rotated to a required angle, avoiding the randomness caused by manual rotation, and maintaining the accuracy of the engine cylinder head flipping;

[0027] More specifically, a limiting sliding groove is provided inside the base 4 for providing sliding of the rack 402, and the limiting slide bar 401 is located in the limiting slide bar, the inner walls on both sides of the limiting slide bar are inclined toward the center of the limiting slide bar, and the side of the limiting slide bar 401 close to the inner wall of the limiting slide bar is provided with an inclined surface parallel to the inner wall of the limiting slide bar, and the rack 402 can be limited by the mutual cooperation of the limiting slide bar 401 and the limiting slide bar to prevent the rack 402 from disengaging from the limiting slide bar during the sliding process.

[0028] In one embodiment, if Figure 2 and Figure 3 As shown, a connecting block 404 for driving the rack 402 to slide is fixedly installed on one side of the rack 402, a cylinder 405 for providing sliding power for the limit slide 401 is installed on one side of the base 4, and a push plate 406 is fixedly installed on the output end of the cylinder 405, and the push plate 406 and the connecting block 404 are slidably connected to each other;

[0029] Specifically, a mounting seat 407 for fixing the cylinder 405 is fixedly installed at one end of the cylinder 405 away from the push plate 406, and the mounting seat 407 is fixedly installed on the outer surface of the base 4, and the cylinder 405 is connected to the push plate 406 to drive the connecting block 404 to control the limiting slide bar 401 to slide inside the base 4;

Specifically, the push plate 406 drives the connecting block 404 to pull the limit slide 401 and the rack 402 to move so that the moving rod 408 The sliding range of the limit slide 401 is controlled along the moving groove. When the limit slide 401 moves to the bottom of the moving groove, the connecting block 404 moves downward along the pushing plate 406, and the cylinder 405 retracts, pulling the limit slide 401 to move in the opposite direction, and under the action of the spring 410 and the top block 409, the moving rod 408 and the limit slide 401 are pushed back to the initial position to avoid the restriction of the limiting structure on the gear 403, which causes the gear 403 to only rotate to one side, thereby affecting the resetting of the rack 402.

[0031] In another embodiment, if Figure 5 As shown, the limiting structure includes a fixed rod 5, which is installed inside the gear 403 and is fixedly connected to the rotating rod 3.

[0032] Specifically, the spring sheet 503 is installed at the lower end of the rotating plate 504, so that the spring sheet 503 always pushes the rotating plate 504 upward to fit with the ratchet ring 505. The spring sheet 503 drives the rotating plate 504 to abut against the ratchet ring 505, so that the ratchet ring 505 can only rotate in one direction, effectively preventing the engine cylinder head from flipping randomly due to its own gravity.

[0033] A deep groove ball bearing 6 for reducing friction is fixedly installed on the outer wall of the rotating rod 3, and the deep groove ball bearing 6 is fixedly installed inside a group of flip hangers 1. The deep groove ball bearing 6 is driven by the rotating rod 3 to rotate inside the flip hanger 1, and the deep groove ball bearing 6 is used to reduce the friction between the rotating rod 3 and the flip hanger 1, thereby extending the service life of the device.

[0036] Furthermore, if Figure 1 , Figure 7As shown, a lifting structure is installed at the top of the connecting frame 2, and the lifting structure includes a top frame 8, the top frame 8 is located at the top of the connecting member 2, a motor 9 is fixedly installed at the bottom end of the top frame 8, a transmission rod 10 is fixedly installed at the output end of the motor 9, a winding drum 11 is fixedly installed on one side of the transmission rod 10, and a rope 12 is wound around the outer surface of the winding drum 11, and the rope 12 is fixedly connected to the upper surface of the connecting frame 2 through a pull ring 13 fixedly installed at the bottom end thereof; specifically, the winding drum 11 is fixedly installed at the bottom end of the top frame 8 through connecting members installed on both sides thereof.

[0037] The working principle of the utility model is:

[0038] First, start the motor 9 to connect the transmission rod 10 to drive the winding drum 11 to rotate, and connect the rope 12 to release the whole device downward, so that the clamping plate 7 fits the two sides of the engine cylinder head, and then start the drive motor 702, so that the output end of the drive motor 702 drives the rotating shaft 701 to rotate, so that the two sets of clamping plates 7 are synchronously close to the engine cylinder head along the rotating shaft 701, so as to clamp and fix the engine cylinder head, and then rotate the winding drum 11 in the opposite direction, pull the rope 12 and the engine cylinder head to rise, and after lifting, start the cylinder 405 to connect the push plate 406 to drive the connecting block 404 to pull the limit slide bar 401 and the moving rod 408 to move along the moving groove, so that the gear The bar 402 connects to the gear 403 to drive the rotating rod 3 to rotate, thereby driving the connecting frame 2 and the engine cylinder head to flip over, so as to facilitate multi-angle processing operations. At the same time, during the rotation of the gear 403, the spring sheet 503 arranged therein pushes the rotating plate 504 upward to abut against the ratchet ring 505 installed on the inner wall of the gear 403, so that the gear 403 can only rotate in one direction, thereby preventing the engine cylinder head from rotating in the opposite direction and swinging back and forth. In addition, the moving rod 408 slides around the moving groove, and with the action of the retraction of the cylinder 405 and the spring 410 pushing the top block 409 upward, the auxiliary limiting slide bar 401 is reset for subsequent use.
