[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 3 As shown, an engine turning frame for vehicle maintenance comprises a base 1, a cylinder 9 and a protective shell 6 sleeved on the outside of the cylinder 9 are fixedly installed on the left upper end of the base 1, a moving box 10 is fixedly installed on the output end of the cylinder 9, a connecting plate 15 is fixedly installed on the front bottom and the rear bottom of the moving box 10, and the two connecting plates 15 extend to the outside of the moving box 10 away from the side of the moving box 10, a transmission rod 11 and a transmission rod 2 13 are rotatably connected to the inside of the moving box 10, a worm wheel 12 and a worm 14 are fixedly installed on the outer surfaces of the transmission rod 11 and the transmission rod 2 13, and the worm 14 is meshed with the worm wheel 12, one side of the transmission rod 2 13 extends to the outside of the protective shell 6 and is fixedly installed with a turntable, and one side of the transmission rod 11 extends to the outside of the moving box 10 and is fixedly installed with a fixing plate for fixing the engine;

[0026] A lifting plate 2 and a supporting plate 8 are provided on the upper side of the base 1. The right part of the supporting plate 8 is an open structure without a right side wall. The lifting plate 2 and the supporting plate 8 are provided with an adjustment mechanism 3 for supporting the supporting plate 8 on the side close to each other. The adjustment mechanism 3 is composed of four lifting components 31 and a positioning component 32 for limiting the position of the lifting components 31. Two connecting rods 5 are fixedly installed on the left part of the upper end of the lifting plate 2, and the two connecting rods 5 are respectively fixedly connected to the connecting plate 15 located on the same side;

[0027] As can be seen from the above, the engine is first placed on the support plate 8, and then the engine is connected to the fixed plate with bolts. After that, the cylinder 9 is extended to control the engine to move up to a height suitable for the staff to inspect. During the disassembly and assembly of the engine, the turntable can be rotated to accurately control the rotation angle of the engine by using the worm gear 12 and the worm 14 to reduce the visual blind spot, and the one-way transmission characteristics of the worm gear 12 and the transmission rod 13 can be used to prevent the engine from rotating, thereby facilitating the staff to disassemble and repair the engine.

[0028] Furthermore, a through groove 7 is provided on the left portion of the bottom wall of the support plate 28, which vertically penetrates the side wall of the support plate 28. A conduit for discharging waste oil is fixedly installed on the left portion of the lower end of the support plate 28. In order to prevent the residual oil in the engine from accumulating in the support plate 28, affecting the staff's maintenance of the engine, or directly flowing on the ground and polluting the environment, the through groove 7 and the conduit are provided to discharge the spilled residual oil, thereby reducing the cleaning burden of the staff and improving the environmental protection of the device.

[0029] Furthermore, the inner bottom wall of the supporting plate 2 8 is an inclined surface with a lower left side and a higher right side, so as to promote the flow of oil and accelerate the discharge of oil.

[0030] The four lifting components 31 are respectively located at the four corners of the lower end of the supporting plate 2 8. For the convenience of description, only one of the lifting components 31 is described below. Figure 4 As shown, the lifting assembly 31 includes a screw rod 312 fixedly connected to the lower end of the supporting plate 2 8 and a rotating wheel 311 rotatably connected to the upper end of the lifting plate 2. The pitch of the screw rod 312 surface is relatively large, so that the screw rod 312 can move up under the action of the strong spring 313 after moving down. The lower end of the screw rod 312 passes through the side wall of the lifting plate 2 and extends to the lower side of the lifting plate 2. The rotating wheel 311 is sleeved on the outer side of the screw rod 312 and is threadedly connected to the screw rod 312. A strong spring 313 wound around the outer side of the screw rod 312 is provided between the upper end of the rotating wheel 311 and the lower end of the supporting plate 2 8.

[0031] Since the shape of the engine is irregular, in order to prevent the supporting plate 28 from affecting the rotation of the engine, a lifting assembly 31 is provided so that the supporting plate 28 can support the engine and reduce the force on the fixed plate, thereby improving the structural stability of the device;

[0032] As can be seen from the above, when the engine needs to be flipped, the support plate 28 is first pressed down to expand the distance between the engine and the support plate 28 to provide space for the engine to flip. After the engine is flipped, the support plate 28 is moved up under the action of the strong spring 313 to re-support the engine. Finally, the lifting assembly 31 in the current state is fixed by the positioning assembly 32 to improve the supporting effect of the support plate 28, thereby improving the structural stability of the device.

[0033] Furthermore, the middle portion of the outer surface of the rotating wheel 311 is a polygonal column structure for easy locking, so as to limit the rotation of the rotating wheel 311 by clamping.

[0034] Specifically, Figure 5 As shown, the positioning assembly 32 includes two groups of mobile card groups, and the mobile card groups are composed of two mobile rods 321, and the two mobile rods 321 are respectively located at the front and rear sides of the rotating wheel 311, and the ends of the two mobile rods 321 close to each other are fixedly installed with staggered racks 323, and the ends of the two mobile rods 321 close to each other are provided with storage grooves 322 for storing the racks 323, and the storage grooves 322 on any mobile rod 321 are used to store the racks 323 on the other mobile rod 321 in the same group. 23. The upper end of the lifting plate 2 is rotatably connected with a gear 2 325 and two gears 1 324. The gear 2 325 is located between the two gears 1 324. The two gears 1 324 are respectively located between the two moving rods 321 in the same group. The gear 1 324 is meshed with two racks 1 323 located on the same side. The two moving rods 321 located in the middle of the four moving rods 321 are fixedly installed with staggered racks 2 326 at their ends close to each other, and the two racks 2 326 are meshed with the gear 2 325.

[0035] It can be seen that when the current state of the lifting component 31 needs to be fixed, one of the moving rods 321 is pushed to move in the direction of the rotating wheel 311, and then the moving rod 321 will control the other moving rod 321 in the same group to move in the direction of the rotating wheel 311 through the rack 1 323 and the gear 1 324. When one of the moving card groups starts to move, the gear 2 325 and the rack 2 326 will control the other moving card group to move together, clamp the other two rotating wheels 311, and prevent the rotating wheels 311 from rotating, thereby limiting the current state of the lifting component 31, thereby improving the structural stability of the device.

[0036] Further, such as Figure 1 and Figure 6 As shown, the right part of the supporting plate 2 8 is rotatably connected to the supporting plate 1 4, and the right part of the front side wall and the right part of the rear side wall of the supporting plate 2 8 are both provided with a moving groove, and the inner side of the moving groove is horizontally slidably connected with an L-shaped stopper 16 for supporting the supporting plate 1 4;

[0037] It can be seen that initially, the support plate 1 4 can be tilted to act as a guide rail bracket, making it convenient for the staff to place the engine on the support plate 2 8;

[0038] During operation, the support plate 4 can be placed horizontally and then fixed by an L-shaped stopper 16, so that the support plate 4 serves as a temporary workbench, which is convenient for workers to place tools and structural parts removed from the engine.

[0039] Therefore, the specific working mode of the present invention is:

[0040] First, the engine is placed on the supporting plate 2 8 by tilting the supporting plate 1 4, and then the engine is connected to the fixed plate with bolts. After that, the cylinder 9 is extended to control the engine to move up to a height suitable for maintenance by the staff. When the engine rotation is controlled by the turntable, worm wheel 12 and worm 14 and other structures, the supporting plate 2 8 is pressed down to expand the distance between the engine and the supporting plate 2 8 to provide space for the engine to flip. After the engine flips, the supporting plate 2 8 is moved up again under the action of the strong spring 313 to re-contact the engine, and then one of the moving rods 321 is pushed toward the rotating wheel 311. When the lifting assembly 310 is in the state of being moved in the first direction, the moving rod 321 will control another moving rod 321 in the same group to move toward the direction of the rotating wheel 311 through the rack 1 323 and the gear 1 324. When one of the moving card groups starts to move, the gear 2 325 and the rack 2 326 will control the other moving card group to move together, clamping the other two rotating wheels 311 to prevent the rotating wheels 311 from rotating, thereby limiting the current state of the lifting assembly 31, enabling the support plate 2 8 to stably support the engine and disperse the force on the fixed plate, thereby improving the structural stability of the device and further increasing the service life of the device.

[0041] It should be noted that the specific installation method, circuit connection method and control method of the cylinder 9 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
