Description

TECHNICAL FIELD

[0001] The application relates to a transmission device, in particular to a transmission device of a conveying device in aluminum alloy wheel rim preparation, and belongs to the technical field of transmission devices. BACKGROUND

[0002] A hub, also known as a wheel rim, is a cylindrical part used to support a tire and is centrally fitted on a shaft. Common hubs include steel hubs and aluminum alloy hubs. Steel rims have high strength and are often used in large load-bearing vehicles, but are gradually being replaced by aluminum alloy rims due to their heavy weight and single outer shape. In the preparation process of aluminum alloy rims, multiple processes are often required to form the final product. In order to improve work efficiency, preset conveying devices are often used to convey the rims to be processed between multiple processes. The transmission device is the driving part of the entire conveying device, which can transmit power from the power device to the working mechanism. Reducers are often used as transmission devices in conveying devices to reduce the speed of the motor, increase the output torque, and reduce the load.

[0003] Since the reducer reduces the speed of the motor by rotating the large gear and the small gear inside during operation, the large gear and the small gear need to be lubricated to ensure smooth rotation. However, the existing method for supplementing lubricating oil to the reducer is to unscrew the oil plug of the oil inlet, manually add lubricating oil through a funnel, and manually hold the funnel with one hand and pour oil into the funnel with the other hand. While pouring oil into the funnel, the operator must also pay attention to the oil injection situation of the oil inlet. If not careful, the funnel and the oil inlet may be separated, causing oil leakage, which is not convenient for single-person operation. If the reducer is damaged during operation, it will directly affect the entire wheel rim production line. SUMMARY

The side close to each of the plurality of second electric sliding blocks 23 is provided with a rotating seat 24, and each of the plurality of first electric telescopic rods 25 is hingedly connected to the rotating seat 24 close to it through a rotating block arranged at the bottom end. The plurality of first electric telescopic rods 25 can support the funnel during oil filling work, facilitating single-person oil filling work of the worker.

[0041] As a technical optimization scheme of the present application, the side close to each of the two rotating plates 4 is provided with a rubber pad 16, and the side away from the two rotating plates 4 of the fixed frame 3 is provided with a rectangular plate 15, and the bottom of the rectangular plate 15 is provided with a sponge pad 18. The rubber pad 16 can be arranged to block the oil inlet 7 by rotating the two rotating plates 4 downward after the oil filling work is completed; the sponge pad 18 can be arranged to wipe the top of the filter plate 10 after the steel wire brush 19 cleans the impurities on the top of the filter plate 10, thereby improving the cleanliness of the top of the filter plate 10.

[0042] As a technical optimization scheme of the present application, the auxiliary connecting mechanism includes two second electric telescopic rods 26, and each of the two second electric telescopic rods 26 is arranged on the outer wall of the speed reducer body 1 close to the first connecting shaft 5. The extending end of each of the two second electric telescopic rods 26 is provided with an arc-shaped clamping block 6.

[0043] As a technical optimization scheme of the present application, the side away from the second electric telescopic rod 26 of each of the two arc-shaped clamping blocks 6 is provided with a movable slot, and two movable blocks are slidingly arranged in each of the two movable slots. One end of each of the plurality of movable blocks away from the arc-shaped clamping block 6 is provided with two connecting plates 27 that cooperate with each other, and the upper and lower ends of each of the two connecting plates 27 are threadedly connected through a bolt 28. The auxiliary connecting mechanism can be arranged to connect the first connecting shaft 5 of the speed reducer body 1 and the output end of the motor through the two connecting plates 27 and the two bolts 28 without a shaft coupling, thereby facilitating connection between the speed reducer body 1 and the motor.

[0044] When the staff finds that the lubricating oil inside the decelerator body 1 is used up and needs to add lubricating oil to the inside of the decelerator body 1, at this time, the rotation of the rotating shaft 9 can be controlled to drive the mounting plate 8, the filter plate 10 and the circular plate 11 to rotate together, and after the filter plate 10 is rotated to the top of the oil inlet 7, according to the size of the funnel used for adding lubricating oil, the two first electric sliding blocks 20 are controlled to move in the first sliding groove 17 towards the approaching or moving away direction, driving the position of the two mounting seats 21 and the rotating plate 4 inside to adjust, after adjusting the position of the two mounting seats 21, control the two rotating plates 4 to rotate upwards to a vertical state, then adjust the length of the two mounting seats 21 and the rotating plate 4, after adjusting the length of the two mounting seats 21 and the rotating plate 4, control the extension of the extension end of the plurality of first electric telescopic rods 25 upwards, until the extension end of the plurality of first electric telescopic rods 25 contacts with the outer wall of the funnel body, at this time, the plurality of first electric telescopic rods 25 can assist in supporting the funnel, facilitating the staff to add lubricating oil alone, without the need for other personnel to hold the funnel or one hand to hold the funnel and the other hand to add oil, improving the efficiency of adding lubricating oil, and the extension length of the plurality of first electric telescopic rods 25 is adjustable, which can be suitable for supporting funnels of different lengths.

[0045] When the funnel used by the staff to add lubricating oil is too short and the plurality of first electric telescopic rods 25 cannot support it, the distance between the two rotating plates 4 can be adjusted according to the size of the funnel, then the plurality of first electric telescopic rods 25 can be controlled to rotate downwards to a horizontal state in the rotating seat 24 through the rotating block at the bottom end, and at the same time, the plurality of second electric sliding blocks 23 are controlled to move in the corresponding second sliding groove 22 towards each other, driving the plurality of first electric telescopic rods 25 in a horizontal state to also move towards each other, which can clamp and fix the bottom tubular outer wall of the funnel. Since the funnel is located between the two rotating plates 4, the rubber pad 16 on the side of the two rotating plates 4 approaching each other can clamp and fix the outer wall of the funnel, so that the upper and lower ends of the funnel are clamped and fixed, thereby facilitating the staff to add oil.

[0046] After the oiling inside the reducer body 1 is completed using the funnel, the auxiliary supporting mechanism can be controlled to continue supporting the funnel, facilitating oil control treatment of the funnel, so that the lubricating oil attached to the inner wall of the funnel can drip downward to the inside of the reducer body 1 in the oil control process, avoiding waste; after oil control, a small amount of lubricating oil will still be attached inside the funnel, at which time the mounting plate 8, filter plate 10 and circular plate 11 can be rotated together by the rotating shaft 9, the circular plate 11 is controlled to rotate to the top of the oil inlet 7, and then the inflatable air bag 12 installed inside the circular plate 11 is inflated and elongated upward, so that the inflatable air bag 12 extends into the tubular inner wall of the funnel. Since the outer wall of the inflatable air bag 12 is attached with oil-absorbing cotton, the oil-absorbing cotton can absorb and collect the lubricating oil attached to the tubular inner wall of the funnel during contact between the outer wall of the inflatable air bag 12 and the tubular inner wall of the funnel, and during the resetting of the inflatable air bag 12, the lubricating oil absorbed by the oil-absorbing cotton is squeezed and discharged into the groove inside the circular plate 11, and finally through the oil outlet 14 opened at the bottom of the circular plate 11, it is introduced into the oil inlet 7. On the one hand, this part of the lubricating oil can be avoided to be wasted, on the other hand, the lubricating oil attached to the tubular inner wall of the funnel can be cleaned, without the need for subsequent staff to spend a lot of time cleaning the tubular inner wall of the funnel, facilitating the subsequent use of the funnel.

[0047] After the oiling of the reducer body 1 is completed, if there are impurities in the lubricating oil, the impurities will remain on the top of the filter plate 10. The filter plate 10 can be rotated while rubbing against the steel wire brush 19 arranged at the bottom of the two mounting seats 21, so that the steel wire brush 19 can automatically clean the impurities on the top of the filter plate 10. When the filter plate 10 is rotated to below the rectangular plate 15, the sponge pad 18 installed at the bottom of the rectangular plate 15 can also wipe the impurities and a small amount of lubricating oil that are not completely cleaned on the top of the filter plate 10, facilitating subsequent positioning of the filter plate 10 at the top of the oil inlet 7. When the reducer body 1 is cooled and exhausted through the oil inlet 7, dust and other impurities outside are not easy to attach to the top of the filter plate 10; when the filter plate 10 is positioned at the top of the oil inlet 7 to prevent dust or other impurities from entering the inside of the reducer body 1, dust accumulated on the top of the filter plate 10 can also be controlled to rotate the filter plate 10 with the rotating shaft 9 to rub against the steel wire brush 19 to clean the dust accumulated on the top of the filter plate 10.

[0048] And when the oil inlet 7 is not used, the two rotating plates 4 can be controlled to rotate downward to the horizontal state, so that the two rotating plates 4 drive the two rubber pads 16 to block the oil inlet 7, at this time the two rotating plates 4 can be used as blocking cover plate, and cooperate with the filter plate 10, when the reducer body 1 needs to exhaust, the two rotating plates 4 can be controlled to open the exhaust, and at this time the round plate 11 at the other end of the mounting plate 8 is located below the rectangular plate 15, the rectangular plate 15 and the sponge pad 18 at the bottom can seal the top of the round plate 11, avoid the internal recess of the round plate 11 from easily attaching dust when not in use, so that the dust in the recess flows into the inside of the reducer body 1 with the cleaned lubricating oil, affecting the gear rotation of the reducer body 1.

The preferred embodiments do not describe all the details and limit the application to the specific embodiments described. Obviously, according to the content of the specification, many modifications and changes can be made.
