Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway vehicle production and maintenance technology, specifically a bearing press-fitting machine and gantry robot used in the wheelset temperature pressing chamber. Background Technology
[0002] Currently, in the wheel and axle workshops of railway vehicle depots or rolling stock plants, the "entry" and "exit" of wheelsets in the same-temperature pressing chamber are achieved manually by pushing the wheelsets forward on the ground track. The ground track serves as the carrier for transporting wheelsets, the route for wheelset operations, and also has a certain dynamic storage function for wheelsets. This means that wheelsets cannot be staggered, intersected, or densely arranged when buffered in the same-temperature pressing chamber. Its biggest drawback is that the ground track occupies a large amount of production area, resulting in high labor intensity for workers and low work efficiency. Summary of the Invention
[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a bearing press-fitting machine and gantry robot for wheelset pressing in a same-temperature pressing chamber, so as to solve the problems mentioned in the background art.

The bearing pressing machine 3 includes pressing station 3A, exit position 3C, and conveyor 3D. The conveying of wheelsets 1A without bearings from storage position 1B to storage position 4A and from storage position 4A to pressing station 3A is completed by gantry robot 5. The conveying from pressing station 3A to exit position 3C is completed by conveyor 3D.

[0006] As a further embodiment of the present invention: the conveyor 3D includes a two-station inclined rail conveyor 6, which includes a two-station inclined rail 6A and a two-station stopper 6B; the high position and the low position of the two-station inclined rail 6A are located at the pressing position 3A and the exit position 3C, respectively, and the two-station stopper 6B is located between the pressing position 3A and the exit position 3C; when the two-station stopper 6B retracts, the wheelset 1A that has completed its work at the pressing position 3A rolls to the exit position 3C.
[0007] As a further embodiment of the present invention: the pressing station 3A includes a buffer station 3A1 and a pressing station 3A2, and the conveyor 3D includes a three-station inclined rail conveyor 7, which includes a three-station inclined rail 7A, a rear stopper 7B, and a front stopper 7C; the high and low positions of the three-station inclined rail 7A are located at the buffer station 3A1 and the exit station 3C, respectively; the rear stopper 7B is located between the buffer station 3A1 and the pressing station 3A2, and the front stopper 7C is located between the pressing station 3A2 and the exit station 3C; when the rear stopper 7B retracts, the wheelset 1A waiting to be worked on the buffer station 3A1 rolls to the pressing station 3A2; when the front stopper 7C retracts, the wheelset 1A that has completed its work on the pressing station 3A2 rolls to the exit station 3C.
[0008] As a further aspect of the present invention: the conveyor 3D includes a lifting device 8 located on the pressing station 3A, which lifts and adjusts the height of the wheelset 1A to complete the positioning of the wheelset 1A on the bearing pressing machine 3.
[0009] In summary, compared with traditional technologies, the transportation of wheelsets in the same-temperature pressing room is completed by gantry robots, which eliminates the need for ground tracks. Furthermore, wheelsets can be staggered, crossed, and densely stored, resulting in a smaller production footprint, lower labor intensity for workers, higher operational efficiency, and a higher degree of automation.
