Description

Technical Field

[0001] The utility model relates to the technical field of engine maintenance, in particular to a high-strength engine body turning device. Background Art

[0002] The engine flip stand is widely used in the installation and maintenance of vehicle engines. The engine can be flipped 360° on the flip stand, which is convenient for disassembling and assembling parts on the engine. In addition, since the engine body needs to be independently suspended and supported, certain requirements are placed on the strength of the column components of the flip device.

[0003] In order to ensure that the engine has sufficient turning space, some of the current engine turning devices need to install the mounting plate structure connected to the body at a certain height. Therefore, when installing and connecting the body and the mounting plate, it is necessary to use some lifting equipment to lift and move the body. The turning device cannot independently install the engine, and there is room for improvement in practicality. Although some turning frames have lifting effects through structures such as screw rods, they are simply supported by the surface threads of the screw rods, and the engine itself is extremely heavy, and the supporting strength needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a high-strength engine body turning device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-strength engine body flipping device comprises a device base, a lifting structure is fixedly installed on the rear edge of the upper surface of the device base, a body support seat is rotatably installed on the upper end of the lifting structure, the lifting structure comprises a bottom hinged seat, a No. 1 folding rod is hinged at both ends of one side of the bottom hinged seat, and a No. 2 folding rod is hinged at both ends of the other side of the bottom hinged seat, the upper ends of the No. 1 folding rod and the No. 2 folding rod are intersected with the top hinged seat, a No. 1 hinge shaft is rotatably installed between two groups of the No. 1 folding rods, and a No. 2 hinge shaft is rotatably installed between two groups of the No. 2 folding rods, the No. 1 hinge shaft is rotatably connected to one end of the screw rod, and the screw rod is screwed and sleeved with the No. 2 hinge shaft.

[0007] Furthermore, the device base includes a base plate, the four corners of the bottom side of the base plate are fixedly mounted with supporting feet, the upper surface of the base plate is provided with an oil pan placement slot, the oil pan is movably connected to the oil pan placement slot, and lifting handles are fixedly mounted on the edges of both sides of the oil pan.

[0008] Furthermore, a connecting column is fixedly installed in the middle of the upper surface of the top hinge seat, and a locking slot is opened on one side edge of the upper surface of the top hinge seat.

[0009] Furthermore, a handle No. 1 is fixedly mounted on one end of the screw rod.

[0010] Furthermore, the body support seat includes a support seat body, a column connecting groove is opened at the bottom of the support seat body, a spring pin is slidably installed on one side of the support seat body, a flip shaft is rotatably installed through a bearing in the front and rear directions of the support seat body, a worm wheel is fixedly installed in the middle of the flip shaft, a body connecting plate is fixedly installed at the front end of the flip shaft, a worm is rotatably installed through a bearing on both sides of the support seat body, the worm is meshed with the bottom side of the worm wheel, and a No. 2 handle is fixedly installed at one end of the worm.

[0011] Furthermore, the bottom hinge seat is fixedly installed on the rear edge of the upper surface of the base plate.

[0012] Furthermore, the connecting column is rotatably connected to the column connecting groove via a bearing.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the engine is transported to the side of the overall device for installation, the screw is rotated to push the No. 2 hinge shaft, so that the two groups of No. 1 folding rods and the middle of the No. 2 folding rods are bent in opposite directions along the screw surface, so that the No. 1 folding rod and the No. 2 folding rod are gradually folded from the vertical state, and then the body support seat is lowered, which facilitates the direct connection between the body support seat and the engine body. The column part of the traditional engine turning device is optimized to imitate the structure of the mechanical jack for optimization design, ensuring the support strength while giving the body support seat the effect of autonomous lifting, eliminating the need for additional lifting and handling equipment required to install the engine on the body support seat, thereby improving practicality.

[0015] 2. The support seat body and the top hinge seat are designed to be rotatably connected. When the support seat body is lowered to connect the machine body and the machine body connecting plate to each other, the support seat body can be rotated to make the machine body connecting plate point to a suitable direction to connect with the machine body, so as to avoid the existence of the substrate hindering the installation process of the machine body. After the engine is lifted by the lifting structure, the spring bayonet can be inserted into the locking slot to limit the support seat body. In order to prevent the entire flip device from tipping over due to the shift of the center of gravity during the lifting process, the support foot can be fixedly connected to the ground where the entire structure is placed, or the base plate can be pressed with other heavy objects first. The specific method of balancing the center of gravity depends on the working environment. When working, the worm is rotated by the No. 2 handle, and then the worm wheel is rubbed to rotate the flip shaft to flip the engine connected to the machine body connecting plate. The self-locking property of the worm and worm wheel can be used to lock the position of the engine after flipping. BRIEF DESCRIPTION OF THE DRAWINGS

The No. 1 hinge shaft 206 is rotatably connected to one end of a screw rod 208, and the screw rod 208 is screwed and sleeved with the No. 2 hinge shaft 207.

[0024] Specifically, when the engine is transported to the side of the overall device for installation, the screw 208 is rotated to push the No. 2 hinge shaft 207, so that the two groups of No. 1 folding rods 202 and No. 2 folding rods 203 are bent in opposite directions along the surface of the screw 208, so that the No. 1 folding rod 202 and the No. 2 folding rod 203 are gradually folded from the vertical state, and then the body support 3 is lowered, so that the body support 3 and the engine body are directly connected to each other. The column part of the traditional engine flipping device is optimized and designed to imitate the structure of a mechanical jack, which ensures the support strength while giving the body support 3 the effect of autonomous lifting, eliminating the need for additional lifting and handling equipment required to install the engine on the body support 3, thereby improving practicality.

[0025] Embodiment 1

[0026] like Figure 2 As shown, in this embodiment, the device base 1 includes a substrate 101, and support legs 102 are fixedly installed at the four corners of the bottom side of the substrate 101. An oil pan placement slot 103 is opened on the upper surface of the substrate 101. An oil receiving pan 104 is movably connected in the oil pan placement slot 103, and lifting handles 105 are fixedly installed on the edges of both sides of the oil receiving pan 104.

[0027] In this embodiment, the oil receiving pan 104 is used to receive and temporarily store the engine oil and lubricating oil leaked during the disassembly and assembly of the engine body, thereby ensuring the cleanliness of the working environment around the overall structure and avoiding contamination by the leaked engine oil.

[0028] like Figure 1 , 3 As shown, in this embodiment, a handle 209 is fixedly mounted at one end of the screw rod 208 .

[0029] During specific implementation, the No. 1 handle 209 applies force to the screw rod 208 to make it rotate, thereby controlling the folding and unfolding of the two groups of No. 1 folding rods 202 and No. 2 folding rods 203 .

[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to supplement the overall structure which is not mentioned in the first embodiment, it is specifically described how to flip the installed engine body.

[0032] like Figure 1-5As shown, in this embodiment, a connecting column 205 is fixedly installed in the middle of the upper surface of the top hinge seat 204, and a locking slot 210 is provided at an edge of one side of the upper surface of the top hinge seat 204; the body support seat 3 includes a support seat body 301, a column connecting groove 302 is provided at the bottom of the support seat body 301, a spring latch 303 is slidably installed on one side of the support seat body 301, a flip shaft 304 is rotatably inserted and installed through a bearing in the front and rear directions of the support seat body 301, a worm gear 305 is fixedly installed in the middle of the flip shaft 304, and a body connecting disk 306 is fixedly installed at the front end of the flip shaft 304, and a worm 307 is rotatably inserted and installed through a bearing on both sides of the support seat body 301, the worm 307 is meshed with the bottom side of the worm gear 305, and a No. 2 handle 308 is fixedly installed at one end of the worm 307; the bottom hinge seat 201 is fixedly installed on the rear edge of the upper surface of the substrate 101; the connecting column 205 is rotatably connected to the column connecting groove 302 through a bearing.

[0033] In specific implementation, the support seat body 301 and the top hinge seat 204 are designed to be rotatably connected. When the support seat body 301 is lowered to connect the machine body and the machine body connecting plate 306 to each other, the support seat body 301 can be rotated to make the machine body connecting plate 306 point to a suitable direction to connect with the machine body, so as to avoid the existence of the base plate 101 hindering the installation process of the machine body. After the engine is lifted by the lifting structure 2, the spring bayonet 303 can be inserted into the locking slot 210 to limit and lock the support seat body 301, and lift it. In order to prevent the entire flipping device from tipping over due to the shift of the center of gravity during the process, the support leg 102 can be fixedly connected to the ground where the entire structure is placed, or the base plate 101 can be pressed with other heavy objects first.
