Finally, align the engine holes with the engine frame and fix them, thus completing the installation; during disassembly, first rotate the rocker arm 2, the rocker arm 2 drives the first gear 3 to rotate, the first gear 3 drives the rack 4 to lift, the rack 4 drives the fixed fixture 5 to lift to a suitable position. Then open the fixed fixture 5 so that the engine is located in the fixed fixture 5 and lock the fixed fixture 5. Finally, remove the screws of the engine frame, thus completing the disassembly; in summary, the engine disassembly and assembly fixture of the present application facilitates the disassembly and assembly of the engine to be completed by only one person, thus facilitating the reduction of labor costs, and also equivalent to realizing semi-automatic disassembly and assembly, facilitating the increase of disassembly and assembly efficiency, and at the same time improving the disassembly and assembly accuracy. Among them, the frame body 1 is used to carry the rocker arm 2, the rack 4, etc.; the rocker arm 2 is used to drive the first gear 3 to rotate. In order to increase the rotation performance, the rocker arm 2 and the frame body 1 can be specifically rotatably connected through a bearing; the first gear 3 and the rack 4 mesh, facilitating the lifting of the fixed fixture 5 along the frame body 1.

[0040] Furthermore, asFigure 1 The fixing fixture 5 includes: a base 53 rotatably connected to the rack 4; a first fixture 51 connected to the base 53; a second fixture 52, one end of the second fixture 52 is rotatably connected to one end of the first fixture 51; a locking unit 54, the other end of the first fixture 51 and the other end of the second fixture 52 are locked and connected through the locking unit 54.

[0041] Specifically, the base 53 is used to carry the first fixture 51; the first fixture 51 and the second fixture 52 cooperate to fix the engine. In order to facilitate the increase of the automatic closing performance, one end of the first fixture 51 and one end of the second fixture 52 are preferably rotatably connected through a plurality of torsion springs, and the radial cross-sectional shapes of the first fixture 51 and the second fixture 52 are both preferably semi-circular; the specific structure of the locking unit 54 is not limited, and it can be a plug and a slot, a lock, etc. that cooperate with each other.

[0042] Furthermore, as Figure 1 shown, the fixing fixture 5 further includes two handles 55 respectively connected to both ends of the base 53, and the two handles 55 are axially symmetrically arranged with respect to the base 53. Specifically, the two handles 55 are convenient for the staff to hold, so as to facilitate the rotation of the base 53 around the frame 1; the axially symmetric arrangement is convenient for increasing the distribution uniformity of the two handles 55, so as to facilitate increasing the error tolerance rate of the staff's holding.

[0043] Furthermore, as Figure 1 shown, it further includes an adapter table 6, one end of the adapter table 6 is fixedly connected to the rack 4, and the other end of the adapter table 6 is rotatably connected to the base 53.

[0044] Furthermore, as Figures 1 - 2 shown, it further includes: a lifting plate 71 movably cooperating with the frame 1, the rack 4 is connected inside the lifting plate 71; a mounting plate 72 connected to the lifting plate 71, and the fixing fixture 5 is rotatably connected to the mounting plate 72. Specifically, the lifting plate 71 is carried by the frame 1 and is used to carry the rack 4 and the mounting plate 72; the mounting plate 72 is used to carry the fixing fixture 5, so as to facilitate the fixing fixture 5 to rotate around the mounting plate 72 through the adapter table 6.

[0045] Furthermore, as Figures 1 - 2 shown, it further includes a guide plate 73 connected to the frame 1, and the lifting plate 71 movably cooperates with the guide plate 73. Specifically, the guide plate 73 is carried by the frame 1 and is used to guide the lifting plate 71, so as to facilitate the lifting plate 71 to lift smoothly along the guide plate 73.

Then release the rocker arm 2. Under the gravity of the rack 4, the fixed fixture 5, etc., the second gear 82 drives the card 81 to have a tendency to rotate counterclockwise. Due to the presence of the limiting block 84, the second gear 82 is prevented from driving the card 81 to rotate counterclockwise, thereby preventing the rack 4, the fixed fixture 5, etc. from descending, and generating a good fastening effect; when it is necessary to descend, first pull out the card 81 in a direction away from the frame 1, rotate the rocker arm 2 counterclockwise, and the rocker arm 2 drives the second gear 82 to rotate counterclockwise until the rack 4, the fixed fixture 5, etc. are lowered to a preset position. Then reinstall the card 81 and the frame 1, and make one end of the card 81 abut against the other end of the elastic member 83, and the other end of the card 81 abut against the limiting block 84. Under the gravity of the rack 4, the fixed fixture 5, etc., the second gear 82 drives the card 81 to have a tendency to rotate counterclockwise. Due to the presence of the limiting block 84, the second gear 82 is prevented from driving the card 81 to rotate counterclockwise, thereby preventing the rack 4, the fixed fixture 5, etc. from continuing to descend, and generating a good fastening effect.
