Description

Technical Field

[0001] This utility model relates to the field of flexible side bearing assembly and disassembly technology, specifically to a flexible side bearing assembly and disassembly clamp. Background Technology

[0002] Currently, the disassembly, assembly, and maintenance of components such as brake beams, elastic side bearings, bolster springs, and wedges on railway freight car bogies mainly rely on manual operation. This results in high labor intensity, low work efficiency, high safety hazards, and severe noise and dust pollution. Since freight car bogies mainly come in four common models (K6, K2, K5, and K4, arranged in descending order of maintenance frequency), their structural composition, spatial dimensions, and number of parts differ significantly. This leads to marked differences in manual disassembly and assembly methods, tools used, work procedures, and operation time, especially the disassembly and assembly of bolster springs and wedges, which are particularly complex.

[0003] In recent years, only a few manufacturers have been engaged in the design and development of automated maintenance robots for railway freight car bogies. Only some railway depots have applied industrial robots and machine vision technology to the maintenance of bogie brake beams, bearing saddles, bolster springs, and wedge assembly / disassembly. Automated disassembly and assembly of elastic side bearings has not yet been achieved. Therefore, this utility model proposes a clamping structure for the automated disassembly and assembly of elastic side bearings. Summary of the Invention

[0004] In order to improve the mechanization and automation of railway freight car bogie maintenance, this utility model provides a flexible side bearing disassembly and assembly fixture, which solves the problems of high labor intensity and low work efficiency in the existing bogie flexible side bearing disassembly and assembly process.

[0005] The technical solution adopted in this utility model is: a flexible side bearing assembly / disassembly fixture, characterized in that it includes an electromagnet core, a coil winding, a machine vision camera, and a fixing plate. Both the electromagnet core and the machine vision camera are fixed to the fixing plate. The coil winding is located within the magnetic pole column of the electromagnet core. The machine vision camera collects the size and position information of the positioning boss of the flexible side bearing and controls the energization of the coil winding. The magnetic pole surface of the electromagnet core magnetically attracts the positioning boss of the flexible side bearing. After collecting the size and position information of the positioning boss of the flexible side bearing, the machine vision camera controls the energization of the coil winding, thereby achieving automatic clamping or releasing of the positioning boss of the flexible side bearing by the electromagnet core, further enabling automatic assembly / disassembly of the flexible side bearing in conjunction with an industrial robot.

[0006] Preferably, the electromagnet core has a U-shaped structure, including two magnetic pole posts, each with a coil winding mounted on it. This design is simple in structure and provides a strong magnetic attraction.

[0007] Preferably, the magnetic pole face of the electromagnet core is configured as a cylindrical structure, which can magnetically attract elastic side bearings of different types.

[0008] Preferably, the machine vision camera is mounted directly above the electromagnet core, maintaining a perpendicular viewing angle to the electromagnet core to avoid obstruction and to obtain better field of view for acquiring the size and position information of the positioning boss of the elastic side bearing.

[0009] Preferably, the electromagnet core has four threaded mounting holes at its rear end, through which bolts are used to fix the electromagnet core to the fixing plate. This design features a simple structure, reliable fixing, and convenient assembly and disassembly.

[0010] Preferably, the fixing plate has a mechanical interface that can be precisely connected to the end of the joint of an industrial robot, so that the disassembly and assembly fixture can cooperate with the industrial robot to realize the automatic disassembly and assembly of the elastic side bearing.

[0011] The beneficial effects of this utility model are: after collecting the size and position information of the positioning boss of the elastic side bearing by the machine vision camera, the power on and off of the coil winding is controlled, thereby realizing the automatic clamping or loosening of the positioning boss of the elastic side bearing by the electromagnet core, and further cooperating with industrial robots to realize the automatic disassembly and assembly of the elastic side bearing.

Both the electromagnet core 1101 and the machine vision camera 1103 are fixed to the fixing plate 1104. The coil winding 1102 is located within the magnetic pole column of the electromagnet core 1101. The machine vision camera 1103 collects the size and position information of the positioning boss of the flexible side bearing and controls the energization of the coil winding 1102. The magnetic pole surface of the electromagnet core 1101 magnetically attracts the positioning boss of the flexible side bearing. After the machine vision camera 1103 collects the size and position information of the positioning boss of the flexible side bearing, it controls the energization of the coil winding 1102, thereby achieving automatic clamping or releasing of the flexible side bearing by the electromagnet core 1101, further enabling automatic assembly / disassembly of the flexible side bearing in conjunction with an industrial robot.

[0016] In this embodiment, the magnetic pole surface of the electromagnet core 1101 is set as a cylindrical structure, which can magnetically attract elastic side bearings of different types.

[0017] In this embodiment, the machine vision camera 1103 is installed directly above the electromagnet core 1101, maintaining a perpendicular viewing angle to the electromagnet core 1101 to avoid obstruction, and can have a better field of view to collect the size and position information of the positioning boss of the elastic side bearing.

[0018] In this embodiment, the electromagnet core 1101 has four threaded mounting holes at its rear end. Bolts are used to fix the electromagnet core 1101 to the fixing plate 1104 through the threaded mounting holes. The structure is simple, the fixing is reliable, and the disassembly and assembly are convenient.

[0019] In this embodiment, the fixing plate 1104 has a mechanical interface that can be precisely connected to the end of the joint of the industrial robot, so that the disassembly and assembly fixture can cooperate with the industrial robot to realize the automatic disassembly and assembly of the elastic side bearing.
