[0026] The present utility model will be further described below in conjunction with the accompanying drawings.

[0027] As Figure 1 shown, the gearbox disassembly and assembly device of an embodiment of the present utility model includes an adjusting member 5, a sliding member 7 and a fixing member 8. As Figure 2 shown, the fixing member 8 includes a supporting portion 82 and a first clamping portion 81 provided on the supporting portion 82. The sliding member 7 is slidably arranged on the supporting portion 82 and is opposite to the first clamping portion 81. The adjusting member 5 is arranged on the supporting portion 82 and is connected to the sliding member 7. The adjusting member 5 moves the sliding member 7 on the supporting portion 82 to change the distance between the first clamping portion 81 and the sliding member 7.

[0028] The supporting portion 82 on the fixing member 8 can carry the gearbox 1. The distance between the first clamping portion 81 on the fixing member 8 and the sliding member 7 is adjusted by the adjusting member 5, so as to match the size of the gearbox 1. By changing the position of the sliding member 7, the gearbox 1 can be clamped between the first clamping portion 81 and the sliding member 7, which can conveniently clamp and fix the outer shell of the gearbox 1 and reduce the disassembly difficulty of the gearbox 1. When the gearbox 1 needs to be installed, the gearbox disassembly and assembly device of this embodiment can also be used to clamp and fix the gearbox 1.

[0029] As Figure 3 shown, further, the sliding member 7 includes a slide block 73 and a second clamping portion 71 provided on the slide block 73. The second clamping portion 71 is arranged opposite to the first clamping portion 81. A chute 83 is provided on the supporting portion 82, and the slide block 73 is arranged in the chute 83. The slide block 73 is arranged in the chute 83, which can make the sliding member 7 move stably on the fixing member 8. The first clamping portion 81 and the second clamping portion 71 can jointly clamp the gearbox 1 placed on the supporting portion 82.

[0030] Further, the sliding member 7 further includes a connecting portion 74. Both the slide block 73 and the adjusting member 5 are connected to the connecting portion 74. The adjusting member 5 is connected to the connecting portion 74 to move the whole sliding member 7 on the fixing member 8. In this embodiment, the number of both the slide block 73 and the second clamping portion 71 is two, and the connecting portion 74 connects the two slide blocks 73 into one body, so that the two slide blocks 73 can move synchronously.

[0031] As Figure 1 and Figure 3As shown, the gearbox disassembly and assembly device further includes a mounting base 6. The adjusting member 5 includes a screw rod 52. The mounting base 6 is fixedly connected to the supporting portion 82. The screw rod 52 is threadedly connected to the mounting base 6. The screw rod 52 passes through the mounting base 6 and is connected to the connecting portion 74. The screw rod 52 is parallel to the sliding groove 83. By rotating the screw rod 52, the screw rod 52 will move on the mounting base 6, thus contacting the connecting portion 74 of the sliding member 7 and pushing the entire sliding member 7 to move, thereby changing the distance between the first clamping portion 81 and the second clamping portion 71.

[0032] As Figure 3 shown, the adjusting member 5 further includes a bearing 51. The bearing 51 is arranged between the screw rod 52 and the connecting portion 74. The bearing 51 is a thrust bearing. One side of it is connected to the screw rod 52, and the other side is connected to the connecting portion 74. The bearing 51 can conduct the acting force applied by the screw rod 52 to the connecting portion 74 and prevent the rotating screw rod 52 from directly rubbing against the connecting portion 74, greatly reducing the frictional force, saving effort and protecting the screw rod 52 and the connecting portion 74 at the same time.

[0033] As Figure 3 shown, the adjusting member 5 further includes a handle 53. The handle 53 is arranged at the end of the screw rod 52 away from the connecting portion 74. The handle 53 is for the operator to hold, so that the screw rod 52 can be rotated conveniently and with less effort.

[0034] As Figure 3 shown, the sliding member 7 further includes a backing plate 72. The backing plate 72 is arranged on the surface of the second clamping portion 71 and is opposite to the first clamping portion 81. The backing plate 72 can contact the gearbox 1 directly instead of the second clamping portion 71. The backing plate 72 is made of an elastic material, such as rubber or silica gel, which can prevent the surface of the gearbox 1 from being scratched during the clamping process, and can firmly clamp the gearbox 1 more stably through a certain degree of deformation, avoiding the loosening of the gearbox 1.

[0035] As Figure 1 shown, the gearbox disassembly and assembly device further includes a base 2 and a lifting mechanism 4. The fixing member 8 is arranged on the top surface of the base 2. The lifting mechanism 4 is connected to the bottom surface of the base 2. By adjusting the lifting mechanism 4, the base 2 and the fixing member 8 can be adjusted to a suitable height, enabling the gearbox 1 to be at a height convenient for the staff to operate, and also facilitating the transfer of the gearbox 1, such as transferring it to a repair tabletop.

[0036] As Figure 4 shown, the gearbox disassembly and assembly device further includes a bottom plate 3 and rollers 9. The lifting mechanism 4 is arranged on the top surface of the bottom plate 3. The rollers 9 are arranged on the bottom surface of the bottom plate 3, enabling the gearbox disassembly and assembly device to move as a whole. When the gearbox 1 is disassembled, it can be conveniently transported to the target location, saving time and effort.

[0037] Although the present utility model has been described with reference to the preferred embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any manner. The present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
