[0037] As shown in Figures 1 to 8 The present application provides an engine turnover mechanism which can be applied to different models of engine disassembly and maintenance requirements.

[0038] As shown in Figure 1 The engine turnover mechanism includes a support 11, a turnover structure 12 and a connecting structure 2. The turnover structure 12 is installed on the support 11 to be supported and fixed by the support 11. The connecting structure 2 includes a connecting disc 21 and a plurality of connecting arms 22. The turnover structure 12 is connected with the connecting disc 21 and drives the connecting disc 21 to rotate. The connecting arm 22 is connected with the connecting disc 21 through a locking piece 4 to enable the connecting arm 22 to selectively rotate or be fixed relative to the connecting disc 21. The plurality of connecting arms 22 are arranged on the same side of the connecting disc 21. The connecting arm 22 has an elongated hole 221, the length direction of the elongated hole 221 is in the same direction as the extension direction of the connecting arm 22, and the connecting arm 22 is connected with the engine body 100 through a fastener 200 passing through the elongated hole 221.

[0039] The turnover structure 12 is connected with the connecting disc 21 to drive the connecting disc 21 to rotate. After the connecting arm 22 is connected with the engine body 100, the turnover structure 12 can rotate the engine body 100 to the required angle to meet the maintenance requirements. The connecting arm 22 is connected with the connecting disc 21 through the locking piece 4, and the locking piece 4 can rotate or fix the connecting arm 22 relative to the connecting disc 21, so that the position of the connecting arm 22 can be adjusted. The arrangement of the elongated hole 221 can enable the fastener 200 to be located at different positions, thereby meeting the connection requirements of different engine bodies 100.

[0040] In some embodiments, the turnover structure 12 includes a rotating assembly 121 and a rotating plate 122. The output end of the rotating assembly 121 is fixedly connected with the rotating plate 122 to drive the rotating plate 122 to rotate. The connecting disc 21 is clamped with the rotating plate 122. The output end of the rotating assembly 121 can drive the rotating plate 122 to rotate to enable the connecting disc 21 clamped with the rotating plate 122 to rotate with the turnover structure 12, so as to rotate the engine body 100 to the required angle.

[0041] As shown in Figures 1 to 5As shown, specifically, the connecting disc 21 is fixedly connected with a clamping hook 211, and the connecting disc 21 is clamped with the rotating plate 122 through the clamping hook 211. For example, the number of the clamping hook 211 is at least two, and the connecting disc 21 is clamped with the rotating plate 122 through the clamping hook 211 to connect the connecting disc 21 with the rotating plate 122, facilitating the connection of the connecting disc 21 with the rotating plate 122. When the engine body 100 needs to be repaired, the connecting disc 21 is first disassembled from the rotating plate 122, and then the connecting arm 22 on the connecting disc 21 is fixedly connected with the engine body 100 (see Figure 8 and Figure 9 ). After the connecting disc 21 is connected with the engine body 100 through the connecting arm 22, the engine body 100 is moved to the rotating plate 122 to clamp the connecting disc 21 with the rotating plate 122, thereby completing the installation of the engine body 100 on the engine turnover mechanism.

[0042] In order to avoid the position movement of the connecting disc 21 relative to the rotating plate 122 during rotation, the rotating plate 122 is provided with a limiting groove 123, and the clamping hook 211 is located in the limiting groove 123. The limiting groove 123 can avoid the position movement of the clamping hook 211 relative to the rotating plate 122, thereby ensuring the stability of the engine body 100.

[0043] For example, the number of the clamping hook 211 is at least two, and the number of the limiting groove 123 is one. Both of the clamping hooks 211 are located in the limiting groove 123, and one of the side walls of the two clamping hooks 211 located at the edge is arranged in abutment with the side wall of the limiting groove 123. In this way, the movement of the connecting disc 21 relative to the rotating plate 122 during the rotation of the turnover structure 12 can be avoided, thereby improving the stability of the engine body 100.

[0044] For example, the rotating assembly 121 includes a first rotating shaft, a first bevel gear, a second bevel gear, and a second rotating shaft. The first rotating shaft is fixedly connected with the first bevel gear, the second bevel gear is fixedly connected with the second rotating shaft, the first bevel gear is engaged with the second bevel gear, and the first rotating shaft is fixedly connected with the rotating plate 122. The rotation of the second bevel gear can be driven after the second rotating shaft is rotated. Since the second bevel gear is engaged with the first bevel gear, the first bevel gear rotates with the second bevel gear, thereby rotating the first rotating shaft. The first rotating shaft is connected with the rotating plate 122 to drive the rotating plate 122 to rotate, thereby adjusting the rotation of the engine body 100 to meet the position requirement of the engine body 100.

[0045] In order to facilitate the rotation of the second rotating shaft, the rotating assembly 121 further includes a bearing and a bearing support. The bearing is embedded in the bearing support, and the second rotating shaft is arranged in the bearing to be supported by the bearing support. The bearing can facilitate the rotation of the second rotating shaft, thereby reducing the acting force of rotation.

[0046] In order to facilitate the rotation of the second rotation axis, in some embodiments, as shown in Figure 1 and Figure 3 , the rotating assembly 121 further comprises a handle 124 fixedly connected with the second rotation axis. In order to realize the locking purpose after the rotation of the second rotation axis, in some embodiments, the rotating assembly 121 further comprises a locking member, and a support plate is fixed on the support 11. For example, the locking member comprises a first electromagnetic attraction member fixed on the second rotation axis and a second electromagnetic attraction member arranged on the support plate, wherein the first electromagnetic attraction member is arranged opposite to the second electromagnetic attraction member, and the first electromagnetic attraction member and the second electromagnetic attraction member are attracted to each other after being electrified to realize the locking of the second rotation axis.

[0047] In some embodiments, the bottom of the support 11 is provided with sliding wheels 3. The sliding wheels 3 can drive the support 11 to move, so as to facilitate the movement of the engine turnover mechanism as a whole and realize the purpose of labor saving. At least one of the sliding wheels 3 is a self-locking wheel, and the structure of the self-locking wheel is a prior art which will not be described here.

[0048] In order to increase the connection points of the engine body 100 and the connecting arm 22 to improve the stability of the engine after connection, as shown in Figure 5 , the number of connecting arms 22 is four, and the four connecting arms 22 are arranged in a matrix. It should be noted that the four connecting arms 22 can be selectively rotated or fixed relative to the connecting disc 21.

[0049] In order to facilitate the connection of the fastener 200 through the long strip-shaped hole 221 with the engine body 100, as shown in Figure 1 , Figure 3 , Figure 4 and Figure 6 , the connecting disc 21 is provided with an avoiding hole 212. The fastener 200 can pass through the avoiding hole 212 to connect the connecting arm 22 and the engine body 100, so as to ensure that the threaded hole of the engine body 100 is connected with the fastener 200. For example, the number of avoiding holes 212 is two, and the avoiding holes 212 also play the purpose of weight reduction.

[0050] The side of the connecting disc 21 facing the rotating plate 122 is provided with an avoiding groove 213, and the locking member 4 is located in the avoiding groove 213. The avoiding groove 213 can ensure that the locking member 4 for fixing the engine body 100 does not interfere with the rotating plate 122. The connecting disc 21 is provided with a connecting hole 214, and the connecting hole 214 is arranged at the groove bottom of the avoiding groove 213.

[0051] The side of the connecting arm 22 facing the connecting disc 21 is provided with a connecting stud 222, and the locking member 4 is a nut. After the threaded rod passes through the connecting disc 21, it is threadedly connected with the nut, so as to realize the purpose of rotating or fixing the connecting arm 22 relative to the connecting disc 21.

[0052] As Figure 7 shown, for example, the fastener 200 connecting the engine block 100 and the connecting arm 22 is a bolt or screw.

[0053] The engine turnover mechanism provided by the utility model has the connecting arm 22 with the long strip-shaped hole 221, and the engine block of various engines can be fixed to the engine turnover mechanism, so that the maintenance of the engine block 100 is facilitated, and the corresponding engine turnover mechanism purchased for the maintenance of various engine models is reduced.

[0054] The connecting arm 22 can be adjusted in angle relative to the connecting disc 21, so that the bolt passing through the long strip-shaped hole 221 can be always tightened to the engine block 100.

[0055] In addition, the above are only the preferred embodiments of the utility model and the applied technical principles. Those skilled in the art will understand that the utility model is not limited to the specific embodiments described herein, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the utility model. Therefore, although the utility model is described in more detail through the above embodiments, the utility model is not limited to the above embodiments, and more other equivalent embodiments can be included without departing from the utility model concept, and the scope of the utility model is determined by the appended claims.
