Description

Technical Field

[0001] The utility model belongs to the technical field of automatic guided transport vehicles, and in particular relates to a double-rotation assembled AGV. Background Art

[0002] The existing engine assembly line AGV has only a single rotation and lifting mechanism. Since operators usually only perform assembly work on the left and right sides of the AGV, it is not convenient to assemble the front and rear sides of the engine (along the direction of travel of the AGV). Therefore, this part of the assembly work needs to be completed on other equipment, which has great limitations.

[0003] In the prior art, the AGV body is designed as a welded structure, which has poor economy and convenience in subsequent maintenance.

[0004] For example, a Chinese utility model patent with authorization announcement number CN219689249U discloses an assembly-type AGV, which lifts or rotates materials by means of the provided lifting components and rotating components, and can find a suitable assembly position when assembling materials, thus facilitating assembly operations. However, its disadvantages are that it has only one slewing mechanism, so it can only perform assembly operations on the left and right sides of the AGV, resulting in low equipment utilization and long cross-process transfer time. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a double-rotation assembled AGV.

[0006] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0007] A double-rotating assembled AGV includes a chassis, an upper frame is assembled and connected to the chassis, a driving member is arranged at the bottom of the chassis, a front slewing mechanism is arranged on the side of the upper frame, and a rear slewing mechanism for rotating and changing the position of a workpiece is arranged at the upper end of the chassis. The rear slewing mechanism includes a base plate connected to the chassis, a slewing support installed on the base plate, a pinion gear meshing with the inner ring of the slewing support, and a motor reducer assembly installed at the lower end of the base plate, and the pinion gear is connected to the output shaft of the motor reducer assembly.

[0008] Preferably, a front cover plate assembly, a left side plate assembly and a right side plate assembly are provided on the side surface of the upper frame, and an upper cover plate assembly is provided on the upper end surface.

[0009] Preferably, a rear traction seat for coupling with a material trolley is provided at the rear of the chassis.

[0010] Preferably, a material box for placing assembly tools is provided at one end of the chassis.

[0011] Preferably, the driving member comprises a driving wheel and a bearing wheel.

[0012] Preferably, the load-bearing wheels are arranged at four locations, respectively at the four corners of the chassis.

[0013] Preferably, the chassis is assembled and connected to the upper frame by bolts.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting a front slewing mechanism on the side of the upper rack and a rear slewing mechanism on the upper end of the chassis, the assembly process on the front and rear sides of the engine (along the AGV travel direction) can be completed on one set of slewing mechanisms, which increases the equipment utilization rate and reduces the cross-process transportation time;

[0016] 2. The front cover assembly, left side plate assembly, right side plate assembly and upper cover assembly equipped on the side and upper end of the upper frame not only provide solid external protection for the AGV, but also facilitate the maintenance and repair of internal components, while ensuring the overall sealing, effectively preventing dust and moisture from intruding, and extending the service life of the equipment;

[0017] 3. The design of the tail traction seat enables the AGV to be easily docked with the material cart, greatly expanding its application scenarios, especially in scenarios such as automated warehouses and production line material distribution, which can achieve seamless integration and improve the level of logistics automation and material flow efficiency;

[0018] 4. The material box installed on the chassis integrates the function of carrying assembly tools for AGV, such as automatically delivering tools to designated workstations, reducing manual intervention and improving the continuity and automation of the production process;

[0019] 5. The drive parts include the configuration of drive wheels and load-bearing wheels, especially the load-bearing wheels are distributed at the four corners of the chassis, which ensures that the AGV can still maintain good stability and ground adhesion under load, improves driving safety, and at the same time disperses the load and protects the ground from damage;

[0020] 6. The chassis and upper frame are assembled by bolt connection, which not only simplifies the assembly process and reduces the assembly cost, but also facilitates the rapid adjustment or replacement of parts on site, thus improving the convenience of maintenance;

[0021] In summary, the front slewing mechanism and the rear slewing mechanism of the utility model complement each other in function, which increases the utilization rate of the equipment and reduces the time of cross-process transportation. At the same time, the main body of the AGV is designed as an assembled structure, which is convenient for the later replacement of accessories and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
