Description

Technical Field

[0001] The utility model belongs to the technical field of engine manufacturing equipment, and particularly relates to an engine body turnover device. Background Art

[0002] During the engine assembly and fault disassembly and inspection processes, it is necessary to rotate the engine by 360° to achieve the rapid installation and removal of parts such as piston connecting rods.

[0003] In the prior art, the common practices are generally divided into two types. One is to lift the engine in the air with an electric hoist. The problem with this approach is that the engine cannot be freely stopped at any angle for disassembly, inspection, and assembly. In order to perform maintenance operations on the engine suspended in mid-air, the operator has to adjust their body posture to repair specific components of the engine, which is time-consuming and laborious. The engine suspended in mid-air is in an unstable state and is likely to swing, shake, or vibrate due to external interference or improper operation. As a result, the engine is very likely to collide with the head or other body parts of the operator standing beside, causing injury to the person.

[0004] The other is to place the engine on a support frame customized according to the shape characteristics of the specified engine, and the personnel are responsible for the engine assembly and fault disassembly and inspection. The shape of the support frame is fixed and cannot be applied to multiple engine models. Therefore, the applicable range of the support frame customized according to the shape characteristics of the specified engine has great limitations. Content of the Utility Model

[0040] Referring to Figures 1 - 3 , an engine body flipping device includes a first support frame 10 and a second support frame 11 which are oppositely arranged. There is an installation area for installing the engine body between the first support frame 10 and the second support frame 11. A first installation component is rotatably connected to the first support frame 10. One end of the first installation component close to the installation area is provided with a first installation part for fixing the engine body.

[0041] Those skilled in the art can understand that when assembling an automotive engine, it is necessary to fix the engine housing and install the internal components of the engine and the bolts outside the housing. Specifically, the staff hoist the engine body to the installation area through a hoisting device, and fixedly connect the two opposite side walls of the engine body shell to the first installation part and the second installation part respectively. After the engine housing is fixed, the first support frame 10 and the second support frame 11 support the engine housing to the support height convenient for the staff to carry out installation operations, so that the staff can install the engine components in a normal standing state. The first installation component and the second installation component are designed to be rotatable. The staff can rotate the first installation component, the second installation component or the engine housing to realize the rotational adjustment of the installation surface of the engine housing. The staff can complete the installation of the entire engine without moving positions, improving the work efficiency of engine installation.

[0042] The first installation component and the second installation component are telescopic structures. By controlling the telescopic lengths of the first installation component and / or the second installation component, the distance between the first installation part and the second installation part can be adjusted to adapt to engine housings of different models and body lengths.

By hydraulically driving the first telescopic end of the first hydraulic telescopic rod 20 to extend, the first fixed end moves towards the second fixed end, and the installation area between the first fixed end and the second fixed end becomes narrower; conversely, by hydraulically driving the first telescopic end of the first hydraulic telescopic rod 20 to retract, the first telescopic end drives the first fixed end to move away from the second fixed end, and the installation area between the first fixed end and the second fixed end becomes wider.

[0044] As a specific implementation of the first installation group components, refer to Figures 1 - 3 , the second installation component includes a second hydraulic telescopic rod 21, the second hydraulic telescopic rod 21 has a second telescopic end and a second fixed end, the second fixed end is rotatably connected to the second support frame 11, and the second installation part is fixedly connected to the second telescopic end. The working principle of the second hydraulic telescopic rod 21 is basically the same as that of the first hydraulic telescopic rod 20. The second telescopic end of the second hydraulic telescopic rod 21 and the first telescopic end of the first hydraulic telescopic rod 20 can extend or retract simultaneously, so as to maximize the adjustment range of the distance between the first installation part and the second installation part, and further enable the distance between the first installation part and the second installation part to be adapted to more models of engine casings.

[0047] When it is necessary to rotate the engine housing installed between the first mounting plate 30 and the second mounting plate 31, the driving motor 40 is turned on to drive the driving sprocket 41 to rotate. The driving sprocket 41 drives the first fixed end to rotate through the chain and the driven sprocket 201. It should be noted that the driving motor 40 is preferably a reversible motor that can achieve the forward and reverse functions. Specifically, a reversible motor with the model 90YR120GY38 can be used, but it is not limited to this type of motor. By controlling the forward and reverse rotation of the driving motor 40, the position of the mounting surface of the engine housing is adjusted, which is convenient for the quick installation of the engine.

[0048] The driving motor 40 is a self-locking motor. After the driving motor 40 stops rotating, it will be in a locked state.

[0051] Furthermore, a plurality of second limiting rods 61 are fixedly connected to the second mounting plate 31. The second limiting rods 61 penetrate through the second mounting plate 31 and are slidably connected to the second mounting plate 31. The setting of the second limiting rods 61 facilitates the limitation of the sliding process of the second mounting plate 31. At the same time, the second limiting rods 61 cooperate with the second protective plate 51 to increase the compressive capacity of the second mounting plate 31.

[0052] As a preferred example of the first support frame 10 and the second support frame 11, refer toFigure 1 and Figure 2 Both the bottom of the first support frame 10 and the bottom of the second support frame 11 are provided with support plates 12, and stiffening plates 13 are fixedly connected between the support plates 12 and the side walls of the first support frame 10 and / or the second support frame 11.
