[0002] Transmission boxes with larger specifications are often used in the travel systems of large vehicles. For example, the travel system of a tracked tank is completed by the drive wheel driving the track through the serrations on the edge of the wheel. However, there is an important transmission component inside the drive wheel, which is the side transmission box. The drive wheel of the tank has a large output torque, so the side transmission box is large in size, heavy in weight, and has a complex structure. When assembling the side transmission box, it is often necessary to flip it between the two postures of "lying flat" and "standing up". In the past, the method used was mostly to use a crane to drag obliquely and workers use tools such as crowbars to flip it. This flipping method has great safety hazards and is easy to damage the outer surface of the shell. Therefore, it is urgent to provide a flipping machine to realize the flipping of the side transmission box, so as to ensure that the flipping process of the side transmission box is safe and reliable.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0024] like Figure 1-Figure 4 As shown, a turning machine for a side transmission box disclosed in the present application comprises a stand 1, a channel steel support 2 is provided in the middle position of the stand 1, the upper side of the channel steel support 2 is an open structure, and the shape of this side of the channel steel support 2 matches the contour of the outer side of the side transmission box, and the side transmission box can be placed on the channel steel support 2 from the open part of the channel steel support 2; a rotating shaft 3 is fixedly connected to the two sides of the channel steel support 2 facing each other in width, and a support unit 4 is movably sleeved on the rotating shaft 3, and the support unit 4 is installed on the side plate of the corresponding side stand 1; a driving assembly 5 is provided on the side of the support unit 4 on one side away from the channel steel support 2, and the driving assembly 5 is connected to the rotating shaft 3 on this side.

[0025] In the above embodiments, Figure 1 As shown, the bench 1 of the present application is a support frame for the side transmission box assembly test process. The channel steel support 2 installed in the middle of the bench 1 is a channel-shaped structure, and its upper end is an outward-expanding open structure, which makes it convenient to place the side transmission box on the channel steel support 2. Figure 2 As shown, taking the side transmission box of a tank among heavy vehicles as an example, the general outline of the outside of the side transmission box is composed of multiple cylinders of different diameters. The shape of the open side of the channel steel support 2 of the present application matches the shape of the outer outline of the transmission box. In this way, after the side transmission box is placed on the channel steel support 2, the side transmission box just fits with the channel steel support 2. During the assembly test process, the position of the side transmission box can be relatively stable and will not shake easily. In the actual production process, there are usually various mounting holes on the outer shell of the side transmission box. In order to further improve the stability of the side transmission box, holes can be drilled at positions corresponding to the adjacent mounting holes on the channel steel support 2. In this way, the side transmission box and the channel steel support 2 can be temporarily fixed by bolts and nuts. In this way, during the rotation of the channel steel support 2, it will be more stable and safe.

[0026] The driving assembly 5 of the present application is connected to the rotating shaft 3. The driving assembly 5 can drive the channel steel support 2 to rotate with the side transmission box through the rotating shaft 3, so as to realize the requirements of different states of the side transmission box in the assembly process. Compared with the method of flipping the side transmission box by a crane and a crowbar in the prior art, after the side transmission box is placed on the channel steel support 2 on the present application, if the side transmission box is to be rotated, it is only necessary to drive the channel steel support 2 to rotate around the axis of the rotating shaft 3 through the driving assembly 5, thereby avoiding repeated dragging of the side transmission box by the crane and repeated contact of the side transmission box by the workers with the crowbar, thereby effectively avoiding damage to the surface of the side transmission box, and also avoiding reducing the safety problems caused by inadequate coordination or operational errors when the workers use the crowbar and the crane to flip the side transmission box.

[0027] Furthermore, if Figure 3 As shown, the support unit 4 includes a side partition 41, the lower end of the side partition 41 is fixedly connected to the top of the side plate adjacent to the side stand 1, an ear plate 42 is respectively provided on the opposite side in the length direction of the side partition 41, the two ear plates 42 are fixedly connected to the side partition 41, a support bearing 43 is provided between the two ear plates 42, and the support bearing 43 is fixedly installed on the side partition 41 by bolts; the rotating shaft 3 on the same side of the side partition 41 passes through the side partition 41 and the support bearing 43 in turn, and the rotating shaft 3 is movably connected to the side partition 41 and the support bearing 43.

[0028] In the above embodiments, the ear plates 42 on both sides of the side partition 41 can make the side partition 41 more solid and firm during use, and the support bearings 43 installed on the side partition 41 can not only provide necessary supporting force for the rotating shaft 3, but also ensure that the rotating shaft 3 is sufficiently smooth during rotation.

[0029] Furthermore, if Figure 3 and Figure 4 As shown, the driving assembly 5 includes a reducer 51, the shell of the reducer 51 is installed on the stand 1, the power output end of the reducer 51 is fixedly connected to one of the rotating shafts 3, the power input end of the reducer 51 is fixedly connected to the output shaft of the driving motor 52, and the shell of the driving motor 52 is fixedly connected to the shell of the reducer 51.

[0030] In the above embodiments, the reducer 51 is an independent component composed of a gear transmission, a worm transmission, and a gear-worm transmission enclosed in a rigid housing, and is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the rotation speed and transmitting the torque between the prime mover and the working machine or the actuator. The power input end of the reducer 51 of the present application is connected to the output shaft of the drive motor 52. It can increase the torque by reducing the rotation speed of the drive motor 52, so that the rotating shaft 3 connected to the reducer 51 can have enough power to drive the channel steel support 2 to rotate. The worker can control the rotation angle of the side transmission box by controlling the direction and rotation duration of the drive motor 52, which is simple and convenient to operate.

[0031] Furthermore, if Figure 1 and Figure 4 As shown, a mounting plate 6 is provided at the front end of the channel steel support 2, and an adjusting screw 7 is penetrated through the mounting plate 6. A fastening nut 8 is threadedly connected to the upper part of the adjusting screw 7 and the lower part of the mounting plate 6, and an adjustable support block 9 is installed on the top of the adjusting screw 7.

[0032] In the above embodiment, the adjusting screw 7 provided on the mounting plate 6 of the present application can freely move in the vertical direction after loosening the fastening nut 8 thereon. After the side transmission box is placed on the channel steel support 2, the adjusting screw 7 is used to adjust the adjustable support block 9 to contact the lower side of the large cylindrical shell at the front end of the side transmission box, and the position of the adjusting screw 7 is fixed with the fastening nut 8, so that the overall placement of the side transmission box can be more stable.

[0033] Furthermore, if Figure 4 As shown, a closed baffle 10 is fixedly mounted on one end of the channel steel support 2 away from the adjustable support block 9 .

[0034] In the above embodiments, the closed baffle 10 can play a certain supporting and protecting role when the side transmission box is rotated to a vertical state. When the side transmission box is placed in the channel steel support 2 in the early stage, the closed baffle 10 can also play a certain positioning role, so that the side transmission box can be quickly placed at the corresponding position on the channel steel support 2. Some holes can also be added in the area corresponding to the reserved holes on the end of the closed baffle 10 close to the side transmission box, so that after the side transmission box is placed on the channel steel support 2, the reserved holes on the side transmission box and the holes on the closed baffle 10 can be used to temporarily bolt them together, so that it will be safer and more stable during the process of rotating the side transmission box.

[0035] Furthermore, the reducer 51 is a two-stage worm gear reducer 51 .

[0036] In the above embodiments, the reducer 51 of the present application uses a two-stage worm gear reducer 51, mainly because the main feature of the worm gear reducer 51 is that it has a reverse self-locking function, so that after the worker adjusts the angle of the side transmission box and stops the power output, the worm gear reducer 51 can be automatically locked, thereby keeping the side transmission box in a specific position. In addition, the worm gear reducer 51 has a large reduction ratio, and the input shaft and the output shaft are not on the same axis or on the same plane, which makes it convenient to arrange the drive motor 52 of the present application upward, thereby reducing the demand for space on the stand 1.

[0037] If the total transmission ratio of the reducer 51 of the present application is 1:400, the input end of the drive motor 52 rotates 100 times, and the shaft 3 with the channel steel support 2 and the side transmission box can be turned 90° through the reducer 51. The drive motor 52 of the present application can use a 1.5KW four-stage brake motor, the speed of which is 1400 rpm. The motor can accurately locate, accurately stop, and accurately and quickly reverse. Its brake function uses the power-off brake principle. When the power supply is stopped, it will immediately lock, and the reaction time is less than 0.001 seconds. In combination with the above-mentioned reducer 51, the adjustment angle of the side transmission box can be accurate and stable. In actual use, a limit switch is also installed at the position corresponding to the horizontal state and vertical state of the channel steel support 2 on the stand 1, so that when the side transmission box is turned to the specified position, the turning machine as a whole can automatically stop, making the present application more convenient to use. The above-mentioned parts of these models are all prior art, and their specific principles and use conditions are not repeated here.

[0038] Furthermore, if Figure 1 and Figure 4 As shown, a control cabinet 11 is provided on one side of the stand 1 where the driving assembly 5 is installed. The control cabinet 11 is electrically connected to the driving motor 52 and the reducer 51 .

[0039] In the above embodiment, workers can control the start, stop and direction of the drive motor 52 through the control cabinet 11. The status and some parameters of the reducer 51 and the drive motor 52 can also be displayed through the display panel on the control cabinet 11, so that workers can operate the equipment more conveniently.

[0040] Furthermore, the surfaces of the channel steel support 2 and the adjustable support block 9 that are in contact with the side transmission box are both provided with soft non-metallic materials.

[0041] In the above embodiments, the soft non-metallic material provided on the channel steel support 2 and the adjustable support block 9 of the present application may be a nylon plate or a rubber plate, so that the channel steel support 2 and the adjustable support block 9 will not easily damage the surface of the side transmission box due to friction at the contact portion with the side transmission box.

[0042] The implementation principle of this embodiment is: after the side transmission box is placed on the channel steel support 2 by a crane, during the subsequent assembly process, if the state of the side transmission box needs to be adjusted, the worker can start the drive motor 52 through the button on the control cabinet 11. The drive motor 52 can reduce its speed and increase its torque through the reducer 51, and then rotate the side transmission box through the rotating shaft 3 and the channel steel support 2. When the side transmission box rotates to a suitable position, turn off the drive motor 52, and the side transmission box can stay in the ideal position. Compared with the prior art, the turning machine of this application can not only improve the turning efficiency of the side transmission box, but also only needs one person to operate, which reduces the work intensity, saves costs, and is safer to use.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
