The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0021] Embodiments of the present utility model: As Figure 1 and Figure 2 shown, a transmission disassembly and assembly device includes a base 1, a column 2 is fixedly provided on the top of the base 1, a turnover machine 3 is mounted at the upper end of the column 2, a back plate 4 is fixedly connected to the rotating shaft of the turnover machine 3, and a first part mounting plate 5 and a second part mounting plate 6 are movably mounted on the back plate 4.

[0022] The flipping machine 3 is a prior art and can be directly purchased. By operating the handwheel on the flipping machine 3, the back plate can be rotated 360°, facilitating the assembly and disassembly of the transmission assembly and improving work efficiency.

[0023] In a specific embodiment, two parallel guide rods 7 are provided on the back plate 4. Both guide rods 7 are arranged along the length direction of the back plate 4, and the two guide rods 7 are respectively fixed to the back plate 4 through three fixing seats 8.

[0024] Fixing the guide rod 7 through three fixing seats 8 can, on the one hand, ensure the stability of the guide rod 7 and prevent the guide rod 7 from falling off the back plate 4.

The first moving plate 9 is also slidably connected to the two guide rods 7 through sliders.

[0026] The first moving plate 9 is slidably connected to the guide rod 7 through two sliders, enabling the first moving plate 9 to move along the length direction of the back plate 4 along the guide rod 7. Through the threaded cooperation between the first lead screw 25 and the first nut, when the first lead screw 25 rotates, the first nut moves on the first lead screw 25, thereby realizing the adjustment of the position of the first moving plate 9.

[0027] A first mounting tube is provided on the first moving plate 9. The first mounting tube is coaxial with the first lead screw 25. The first part mounting plate 5 is rotatably installed on the first mounting tube through a bearing. The upper end of the first lead screw 25 penetrates through the first mounting tube and extends above the first part mounting plate 5.

[0028] Through the rotational cooperation between the first part mounting plate 5 and the first mounting tube, the first part mounting plate 5 can not only move along the length direction of the back plate 4 but also rotate around the first mounting tube, facilitating the installation of the parts of the transmission onto the second part mounting plate 6.

[0029] A first positioning pin mounting tube 10 is provided on the first part mounting plate 5. A first positioning pin mounting seat 11 is provided on the first moving plate 9. One end of the first positioning pin 12 penetrates through the first positioning pin mounting tube 10 and is threadedly connected to the first positioning pin mounting seat 11.

[0030] After the first positioning pin 12 is installed on the first positioning pin installation pipe 10 and the first positioning pin installation seat 11, the first part mounting plate 5 faces the second part mounting plate 6. At this time, the first part mounting plate 5 cannot rotate around the first installation pipe, and the first part mounting plate 5 can only rotate around the first installation pipe when the first positioning pin 12 is removed.

[0031] The first part mounting plate 5 is provided with a circular alignment hole 13. A circle of part fixing holes 14 is opened around the circular alignment hole 13 on the first part mounting plate 5. A horizontal bubble 15 is arranged on the first part mounting plate 5.

[0032] Furthermore, a second height adjustment mechanism is provided on the second part mounting plate 6. The second height adjustment mechanism includes a second lead screw 16, a second nut, and a second moving plate 17. The second lead screw 16 is located between the two guide rods 7, and the second lead screw 16 is coaxial with the first lead screw 25. The second lead screw 16 is rotatably installed on the back plate 4 through two bearing seats. The second lead screw 16 is parallel to the two guide rods 7. The second nut is fixedly arranged on the second moving plate 17, and the second nut is also installed on the second lead screw 16, and the two are in threaded connection. The second moving plate 17 is also slidably connected to the two guide rods 7 through sliders. In order to facilitate the rotation of the first lead screw 25 and the second lead screw 16, the ends of the two are designed as square rods.

[0033] The second moving plate 17 is provided with a second installation pipe. The second installation pipe is coaxial with the second lead screw 16. The second part mounting plate 6 is rotatably installed on the second installation pipe through a bearing.

[0034] A second positioning pin installation pipe 18 is opened on the second part mounting plate 6. A second positioning pin installation seat 19 is provided on the second moving plate 17. One end of the second positioning pin 20 passes through the second positioning pin installation pipe 18 and is threadedly connected to the second positioning pin installation seat 19.

[0035] The height adjustment principle of the second part mounting plate 6 is the same as that of the first part mounting plate 5. When the second positioning pin 20 is removed, the second part mounting plate 6 can rotate around the second installation pipe.

[0036] A shaft positioning hole 21 is opened on the second part mounting plate 6. A U-shaped groove 22 is opened at the end of the second part mounting plate 6. A plug end 23 is installed at the end of the second part mounting plate 6. A U-shaped limit block 24 is provided at the upper end of the plug end 23.

[0037] Since the gears on some transmissions are helical gears, in order to facilitate the assembly of the gears, a U-shaped groove 22 is opened at the end of the second part mounting plate 6, so that the helical gears can be installed from the side, solving the problem of difficult assembly of the helical gears. The sealing end 23 and the end of the second part mounting plate 6 are detachably connected by bolts.

[0038] The working principle of the present utility model: Before assembling the transmission, observe the horizontal bubble 15. If it is not level, level it by operating the turning machine 3. Then use the turning machine to turn the back plate 4 by 180° and observe again whether the horizontal bubble is balanced. At this time, the second part mounting plate 6 is located above the first part mounting plate 5. Then the handwheel of the turning machine can be disassembled and installed at the end of the second lead screw 16. Rotate the second lead screw 16 through the handwheel to raise the second part mounting plate 6. Of course, a pneumatic air gun can also be used in cooperation with a socket to rotate the second lead screw 16. Then remove the second positioning pin 20 and rotate the second part mounting plate 6 by 180°; at this time, the housing of the transmission can be installed on the first part mounting plate 5 and fixed with a bolt assembly. During installation, rapid alignment is achieved through the circular alignment holes 13 on the first part mounting plate 5; then restore the second part mounting plate 6 and install the second positioning pin 20 properly. Operate the turning machine 3 to rotate the back plate 4 by 180°. At this time, the first part mounting plate 5 and the transmission housing are located above the second part mounting plate 6; raise the first part mounting plate 5 and the transmission housing by rotating the first lead screw 25. Then remove the first positioning pin 12 and rotate the first part mounting plate 5 and the transmission by a certain angle to facilitate the installation of components such as the gear shaft onto the second part mounting plate 6. After installation, restore the first part mounting plate 5 and lock it with the first positioning pin 12. Complete the assembly of the transmission housing and components such as the gear shaft by adjusting the height of the first part mounting plate 5.
