[0033] Specifically, the fixing frame 2 is fixedly arranged at the front of the base 1, and is used to support and fix the engine 4 in the hybrid powertrain, that is, the engine 4 can be fixed on the fixing frame 2, the translation plate 3 is arranged at the rear of the base 1, and is used to support and fix the motor housing 5 in the hybrid powertrain, that is, the motor housing 5 can be fixed on the translation plate 3, the base 1 is provided with a slide rail 7, the slide rail 7 extends along the axial direction of the hybrid powertrain, and a slider 8 cooperating with the slide rail 7 is arranged below the translation plate 3, and the first driving assembly is arranged between the translation plate 3 and the base 1, and is used to drive the translation plate 3 to slide along the direction of the slide rail 7. Among them, the number of the slide rails is at least two, so that the stable support of the translation plate can be achieved.

[0034] It should be noted that in the hybrid powertrain, the crankshaft of the engine is fixedly connected to the motor rotor, and the motor stator is fixed in the motor housing. When the engine and the motor housing are assembled and separated, the motor stator and the motor rotor can be assembled and separated.

[0035] The working principle of the disassembly and assembly tool in this embodiment is:

[0036] When the engine 4 and the motor housing 5 are to be disassembled and separated, the engine 4 is first fixed on the fixing frame 2, and the motor housing 5 is fixed on the translation plate 3, and then the first driving component drives the translation plate 3 to move away from the fixing frame 2, so that the motor rotor 6 is disengaged from the motor housing 5, thereby realizing the separation of the engine 4 and the motor housing 5. When the engine 4 and the motor housing 5 are to be assembled, it is only necessary to drive the translation plate 3 to move toward the fixing frame 2 through the first driving component, so that the motor rotor 6 is inserted into the motor housing 5, thereby realizing the assembly of the engine 4 and the motor housing 5.

[0037] In summary, the disassembly and assembly tool of this embodiment can realize the automatic disassembly of the motor rotor and the motor stator, the operation is simpler and more convenient, the disassembly and assembly efficiency of the hybrid powertrain is improved, and the disassembly and assembly tool can also be used to disassemble and assemble the motor while it is powered.

[0038] In this embodiment, if Figures 1 to 3 As shown, the first driving assembly includes a first screw 9 , a first nut 10 and a first hand wheel 11 .

[0039] The first lead screw 9 is arranged along the length direction of the slide rail 7 and is fixedly connected to the base 1 through the first bearing. The first hand wheel 11 is coaxially arranged at the rear end of the first lead screw 9. The first nut 10 is sleeved on the first lead screw 9 and is fixedly connected to the translation plate 3. In this way, the first lead screw 9 is driven to rotate by shaking the first hand wheel 11, and then the translation plate 3 is driven to move along the slide rail 7, which makes the operation simpler.

[0040] Among them, the first screw 9 is a self-locking screw, and the first nut 10 is a self-locking nut. When the first hand wheel 11 is not shaken, the first nut 10 and the first screw 9 will not move relative to each other, and the translation plate 3 will not move on the slide rail 7, thereby achieving the movement and positioning of the translation plate 3.

[0041] In this embodiment, if Figures 1 to 3 As shown, the disassembly and assembly tool of the hybrid powertrain further includes a lifting plate 12 and a second drive assembly.

[0042] Specifically, the lifting plate 12 is fixedly arranged on the translation plate 3, and is used to support and fix the motor housing 5, that is, the motor housing 5 is fixed on the translation plate 3 through the lifting plate 12, and the second driving assembly is arranged between the lifting plate 12 and the translation plate 3, and is used to drive the lifting plate 12 to move in the vertical direction relative to the translation plate 3. When the engine 4 is fixed by the fixing frame 2, the height of the lifting plate 12 can be adjusted by the second driving assembly, so that the lifting plate 12 can be fixedly connected with the housing of the engine 4 of different models; in addition, through the adjustment of the second driving assembly, the motor housing 5 can be made to be at the same height as the axis center line of the motor rotor 6, thereby facilitating the disassembly and assembly of the motor rotor 6 and the motor stator.

[0043] Furthermore, if Figures 1 to 3 As shown, the second driving assembly includes a second lead screw 13 , a second nut 14 and a second hand wheel 15 .

The second hand wheel 15 is arranged at the upper end of the second lead screw 13. The second nut 14 is sleeved on the second lead screw 13 and connected to the lifting plate 12. In this way, the second lead screw 13 can be driven to rotate by shaking the second hand wheel 15, thereby driving the lifting plate 12 to move vertically relative to the translation plate 3, and the operation is simpler.

[0045] Among them, the second screw 13 is a self-locking screw, and the second nut 14 is a self-locking nut. When the second hand wheel 15 is not shaken, the second nut 14 and the second screw 13 will not move relative to each other, and the lifting plate 12 will not move in the vertical direction, thereby enabling the lifting plate 12 to be moved and positioned.

[0046] Furthermore, there are four second drive assemblies, which are respectively disposed at four corners of the lifting plate 12 , thereby enabling stable support and movement of the lifting plate 12 .

The second support seat 18 is fixedly connected to the rear end of the motor housing 5 through the second pin hole and the pin, thereby achieving support and fixation of the rear end of the motor housing 5. Of course, in other embodiments, the first support seat and the second support seat can also be an integrated structure.

[0049] In addition, the number of the first pin holes is two, and the number of the second pin hole is one; the hole on the motor housing 5 corresponding to the second pin hole is a waist-shaped hole, and the length direction of the corresponding hole is arranged along the axial direction of the hybrid powertrain. When fixing the motor housing 5, the front end of the motor housing 5 is first fixed to the first support seat 17 through the first pin hole and the pin, and then the rear end of the motor housing 5 is fixed to the second support seat 18 through the second pin hole and the pin, so that the stress generated when the motor housing 5 is fixedly connected to the first support seat 17 and the second support seat 18 respectively can be reduced.

In this way, the horizontal height of the support arm 19 can be adjusted by adjusting the different positions of the bolt in the third fixing hole 20, so that it is suitable for supporting and fixing engines 4 of different models.

[0053] Furthermore, a limiter 21 is provided on the base 1 at the front side of the translation plate 3, and the limiter 21 limits the position of the translation plate 3 when moving on the slide rail 7 to prevent the translation plate 3 from excessively moving toward the front side of the disassembly and assembly tooling.
